(CI. 52-73) This invention relates to cantilever partitions for toilet compartments or other like installations, and more particularly to a partition and bracket support assembly wherein the partition is made up of pre-formed panels of wood or ply-wood provided on their exterior surface with an ornamental and wear resisting coating.

Heretofore in toilet compartments or like installations, the partitions have been made of sheet metal panels usually embodying spaced sheet metal pans of rectangular formation interconnected together at their edges by a variety of edging constructions and supported in a variety of ways from the wall, ceiling and floor. These, due to their all metallic construction, have been expensive, of great weight and oftentimes unsightly by virtue of the exposed fasteners necessitated in their construction. Further, due to their metallic construction, the panels have achieved a most monotonous sameness in appearance affording no mean for aesthetic improvement.

It is accordingly one principal object of this invention to provide a panel construction that is made of wood or ply-wood body, the exterior surface of which has bonded or otherwise secured thereto an ornamental, wear resisting coating of a variety of materials such as plastics, ceramics, metal, plain or embossed, wood veneer, tile of any suitable material; and in fact any type of material metallic or non-metallic or any combination thereof.

It is another object of this invention to interconnect two such panels to provide a single partition with no visible fastening means.

A further object of this invention relates to a bracket arm support projecting from a wall on which a single partition is mounted and secured thereto such that the partition will be wholly supported in cantilever fashion thereby and with no support or connection to the ceiling or floor.

A still further object of this invention relates to a panel and bracket arm support construction designed to permit individual assembly on the job of each panel on the bracket arm support to form a single cantilever partition, wholly concealing the bracket arm support and secured thereto with no visible fastening means.

Another object of this invention relates to a panel and bracket arm support construction wherein the panels are preassem'bled to form a unit handled partition and slid as a unit onto the bracket arm support, wholly concealing the same and secured thereto with no Visible fastening means.

It is still another object of this invention to provide a pair of cantilever bracket arms so designed as to provide for assembly and attachment thereto and to each other of a pair of opposed panels to form a single partition, as well as to mount and have secured thereto a unit handled partition made up of two connected panels; the securement of the panels to the bracket arms in each instance being such as to be wholly concealed and contained within the partition.

A still further object of this invention is to provide: (1) a partition of uniform thickness wherein the opposed panel whether individually assembled on the job on the bracket arms or pro-assembled and connected to provide a unit handled partition to be mounted on the bracket arms are in parallel spaced relation; as well as (2) to provide a wedge-shaped partition wherein the opposed panels are inclined towards each other from rear to front and present the same finished appearance whether individually assembled on the job on the bracket arms or preassembled and connected to provide a unit handled partition to be mounted on the bracket arms.

Another object of this invention relates to the provision of lateral bracing structure disposed between the panels of the partition whether flat, i.e., parallel to each other, or wedge-shaped.

Yet another object of this invention relates to a stile construction with support arms for securing the same to the panels and/or bracket arms interiorly of the partition and including a fastener construction interconnecting the center portion of the stile to the panels interiorly of the partition.

An additional object of this invention relates to an edge filler construction for concealing the panel connecting structure and attaching members of the stile to the partition, and the individual panels and/ or partition unit to the bracket arms.

Another object of this invention is to provide a sealing and/or closure structure for the rear end of the partition permitting individual on the job assembly of the panels on the bracket arms or which may form an integral part of a unit-handled partition.

Still another object of this invention is the utilization of an adhesive to secure the panels and/or partition to a wall when mounted in position on the bracket arms, as well as to secure the panel and partition parts to each other.

A still further object of this invention relates to novel angle bar bracket supports and channel bracket supports which connect together opposed panels making up a cantilever partition and which further mount the panels and/ or partition on the bracket arms.

From the above stated objects of this invention it will be seen that it is the essential purpose of this invention to provide a cantilever partition formed of wood panels that are exteriorly covered with a coating of a variety of materials, that is of great strength and of simple and inexpensive construction, that is easily installed and secured in place, in which there are no visible fastening means and of lasting ornamental beauty.

The invention will be more fully understood, and other objects and advantages thereof will become apparent, from a consideration of the detailed description as appearing hereinafter, taken in conjunction with the accompanying drawings forming a part hereof, in which like reference characters designate like parts throughout the several views, and wherein:

In the copending application of Nathan Schooler for a Combined Floor Supported and Wall Contained Pedestal Structure and Cantilever Partition Assembly, filed February 25, 1964, Serial No. 350,629, there isdisclosed upper and lower bracket arms connected to a pedestal structure within a wall and projecting from. the wall to support a metal cantilever partition that is either of uniform thickness having parallel sides or wedge shaped having sides inclined forwardly toward the front thereof. The cantilever panel structure of this invention is supported on and secured to a bracket arm construction such as shown and described in said copending application.

Referring to the drawings, FIG. 1, a cantilever partition 10 with attached stile 12 is supported on wall 14 with its lower horizontal edge spaced from floor 16. The partition 10 forms one wall of a toilet compartment 18 (only partly shown) provided with a door 20 hingedly mounted on stile 12.

The partition 10 is formed of two parallel side panels 22, 24 of rectangular shape, interconnected and supported in a manner to be hereinafter described. In the preferred embodiment, each panel is formed of wood or plywood provided on its exterior face with a Formica coating bonded thereto, though it is to be understood that any desired ornamental coating may be applied in any desired manner to the exterior face of the panel such as stainless steel or other sheet metal (coated or otherwise), plastic, fabric, leather, ceramic or any other suitable material or combination thereof. The stile 12 is also formed of wood or plywood and in this case all the exposed visible surface is similarly provided with a Formica or other coating 25, see FIG. 4.

The panels 22, 24 by virtue of their manufacture, size and dimensions may either be individually mounted on the upper and lower projecting bracket arms 26, 28 to form the partition 10.; or may be secured together in spaced parallel relation to provide a pre-formed partition to be mounted as a unit on said bracket arms 26, 28, all in a manner as will be hereinafter described.

Thus, for individual panel assembly on the bracket arms 26, 28, each panel 22, 24 has secured to the inner side thereof upper and lower angle bracket supports 30, 32, respectively equally positioned inwardly from the upper and lower edges of the panel. The vertical legs 34 of the angle bracket supports 30, 32 extend towards each other and are seated in complementary formed grooves 36 formed in the panels such as to lie flush with the inside surface thereof, see FIGS. 5 and 6, and are secured thereto by screws 38. The horizontal legs of the angle bracket supports 30, 32 are provided with longitudinally spaced struck-out portions to form lugs 40 and recesses 42, see FIG. 4. The angle bracket supports 30, 32 extend substantially the full width of the panel and are so positioned that when the panels are placed each on one side of the bracket arms 26, 28, the lugs 40 of one angle support bracket will extend into the recess 42 of the other opposed angle support bracket, see FIG. 4, with the lugs 40 of the upper and lower angle support brackets 30, 32 respectively seating on the horizontal edge 26a of the upper bracket arm 26 and on the horizontal edge 28a of the lower bracket arm 28. As will be seen in FIG. 2, the opposed pairs of angle support brackets 30, 32 at their forward ends extend beyond the vertical terminal ends 26b, 28b of the bracket arms 26, 28 and are mitered to engage the mitered ends of vertical bracket connectors 46. 48.

The side leg 46a of bracket connector 46 is seated within a complemental recess 50 provided in the inner side of panel 24, see FIG. 2A, adjacent the front edge thereof and secured in place by screws 52. The front leg 46b is of a length greater than the thickness of the bracket arm 26, and the terminal end thereof is adapted to seat in a recess 54 formed in the front edge of opposed panel 22. The lower bracket connector 48 is similarly formed and attached to the inner side of panel 24. Provided in front leg 46b as also in the front leg 48b is a bolt receiving opening 56 adapted to receive a bolt 58 for a purpose to be hereinafter described.

Formed in each of the inner sides of the panels 22, 24 are like horizontal dove-tailed grooves 62, 64 that extend from the front edge of each panel and terminate short of the rear edge thereof, see FIG. 2 and FIG. 7. Arranged above and below the dove-tail groove 64 on the inner side of panel 24 are wood blocks 68, 70 rigidly secured thereto by an epoxy or other suitable adhesive as well as by screws 72, see FIG. 7. The wood blocks 68, 70 are of a thickness equal to the thickness of bracket arms 26, 28 with their forward edges lying flush with the forward edge of panel 24. Each wood block is provided with a dowel opening 74.

Prior to assembly of the panels 22, 24 on the bracket arms 26, 28 there is adhesively or otherwise secured to the inner side of panel 24 adjacent the rear edge thereof a wood closure strip 76, see FIG. 2, that is fiush with said rear edge and of a length to bridge the distance between the upper and lower bracket arms 26, 28. Instead of being secured to the panel 24, the closure strip 76 may be adhesively or otherwise secured in place direct to the wall 14 between bracket arms 26, 28.

The panel 24 is first placed in position on the bracket arms 26, 28, with the lugs 40 of the angle bracket supports, 30, 32, respectively engaging the horizontal edges 26a, 28a of said bracket arms, with the inner side of the panel engaging the opposed side of the bracket arms and with the rear edge of the panel abutting the wall 14. At least alternate lugs 40 of angle bracket support 30 are to be secured to the horizontal edges 26a, 28a by screws 80 which extend through elongated openings 80a therein. If desired, the rear edge of panel 24 may be secured to the wall 14 by an epoxy or other suitable adhesive. Prior to final attachment of the lugs 40 by screws 80, the panel 24 is held in contact with the wall 14 by bolts 58 which extend through openings 56 in bracket connectors 46, 48 into threaded openings 82 provided in the terminal ends of the bracket arms 26, 28; the bolts 58 further holding the panel 24 in place for placement of the screws 80. With the panel 24 thus mounted and secured in place on the bracket arms 26, 28, the opposite panel 22 is similarly placed in position. It is to be noted that the lugs 40 of the angle bracket supports 30 fixed to panel 22 will be positioned in the recesses 42 provided by the spaced lugs 40 of the opposite already secured in place angle bracket support 30, and that the lugs 40 of the latter angle bracket support will extend into the recesses 42 provided by the spaced lugs of the angle bracket support secured to panel 22 which spaced lugs are similarly to be secured to the horizontal edges 26a, 28a of the bracket arms by screws 80 extending through like elongated openings 80a. As with the panel 24, the rear edge of panel 22 may be adhesively secured to the wall 14.

With the panel 22 so placed in position, the terminal end of each front leg 46b, 48b of bracket connectors 46, 48 will seat in its respective recess 54 provided in the front edge of panel 22, and is secured to the panel by the screw 90, see FIG. 2A. With the rear edges of both panels coated with an epoxy or other adhesive, setting up of the bolts 58 will hold the panels tight against the wall while the adhesive sets. Final attachment of the partition is then effected by screwing down tight the screws 80. Preferably, the exposed sides of the wood blocks 68, 70 are secured to the inner side of panel 22 by an epoxy or other suitable adhesive as at 84, see FIG. 7.

In order to brace as well as to connect the center portions of the panels 22, 24 between the bracket arms 26, 28 to each other, bracing blocks 86 of wood formed with a dove-tail tongue 88 at each end thereof for respective mating engagement with the dove- tail grooves 62, 64 in the inner sides of panels 22, 24, see FIG. 7, are slid into positon from the front end of the panels in spaced relation to each other, as shown in FIG. 2, and secured in place by an epoxy or other suitable adhesive. It is to be noted that the length of the bracing blocks 86 (excluding dove-tail tongues 88) corresponds to the thickness of the bracket arms 26, 28 so that in the final assembly of the panels 22, 24 thereon, the panels 22, 24 will be held in firm parallel relation to each other.

Next applied to the assembled cantilever partition 10 is the stile 12. The stile 12 is of wood or ply-wood, of narrow rectangular form and of a length corresponding to the height of the partition 10. As with the panels 22, 24 the exposed surfaces of the stile 12 are provided wth a Formica coating 25, see FIG. 4. A stile support arm 94, 96 is provided adjacent the top and bottom of the stile 12 projecting therefrom normal to the inside face 12a of the stile, see FIG. 3. Each of the support arms has a vertical leg 94a, 96a, respectively, which seats within a complemental recess 98 so as to lie flush with the inside face 12a of the stile 12 and is secured in place by screws 100. Adjacent to each recess 98 is a screw head receiving recess 104 of any desired shape. At the central portion of the stile 12 are a pair of vertically spaced dowels 106 projecting outwardly from and normal to the inside face 12a. The support arms 94, 96, recesses 104 and dowels 106 all lie in a vertical medial plane normal to the stile 12. The width of each stile support arm 94, 96 is equal to the thickness of the bracket arms 26, 28 and are adapted to seat respectively on the forward lugs 40 of the upper and lower angle support brackets 30, 32. Thus, when the stile 12 is mounted on the forward end of the partition 10, the dowels 106 will enter the dowel receiving openings 74- in blocks 68, 70 and the support arms 94, 96 will snugly seat in the manner described above on the forward lugs 40 between the panels 22, 24, see FIG. 2, with the heads of bolts 58 received in recesses 104. Screws 108 that extend through a recess 42, see FIG. 4, secure the support arms 94, 96

6 to the bracket arms 26, 28, and the inside faec 12a of the stile is secured to the abutting front ends of the panels 22, 24 by an epoxy or other adhesive, as well as to the front face of the wood blocks 68, 70. Similarly the dowels 106 are adhesively secured within the openings 74 to the wood blocks 68, 70. The dowels 106 serve to anchor the vertical central portion of the stile 12 in place to insure a rigid connection as well as a complete engagement of the stile with the front end of partition 10 from top to bottom.

In some cases it may be desirable to employ only a single dowel to secure the mid portion of the stile, in which event the forward bracing block 86a, see FIG. 8, is made of increased height and is provided with a dowel receiving opening 74a, to receive the single dowel 106a carried by stile 12.

Snugly fitted between the panels 22, 24 at the top and bottom edges of the partition 10 are edging filler strips 112, see FIGS. 5, 6. The filler strips 112 are rectangular in cross section, the vertical sides thereof each engaging an inner side of a panel, with the inner side seated on the lugs 40 and the outer side 114 lying flush with the horizontal edges of the panels, as shown in FIGS. 5 and 6. The edging filler strips 112 are secured in place by an epoxy or other adhesive applied to the concealed sides thereof, and are provided on their lower side with a groove 116 to accommodate the heads of screws 81), and are further recessed at their front ends to fit over the stile support arms 94.

It is apparent from the above description that the assembly of the Formica covered panels 24, 25 with Formica covered stile 12 on the bracket arms 26, 28 will provide a cantilever partition of great strength and rigidity without any visible fastening means; and further in view of the attractive appearance of the Formica coating, the partition will have exceptional beauty and appeal. The door 20 which is also Formica coated may be hung on the stile 12 by a concealed gravity and companion hinge assembly (not shown) as described and illustrated in my Patent No. 3,210,799 dated October 12, 1965, to thereby provide a toilet compartment having no visible hardware or fastening elements.

In the event it is not desired to adhesively secure the rear edges of the panels 22, 24 to the wall 14, sealing structure may be provided to prevent the entry of dirt, water and other matter into the interior of the partition 10. Thus, in FIG. 3A, the rear edge of the panel 24a is formed with a vertical groove 120 of any desired shape in which is seated a suitable flexible and deformable sealing element 122 that is compressed to effect a positive seal when the rear edge of the panel contacts wall 14. It is to be understood that the other opposed panel of the partition is similarly provided with a groove 120 and sealing element 122.

In FIG. 3B, a channel shaped metal closure seal 124 is provided having flanged sides 126 which fit into grooves 128 formed in the rear edges of the panels 22b, 24b. The closure seal 124 extends the full height of the partition 10 with the back 130 thereof in direct contact with the wall 14. Slotted openings 132 which extend inwardly from the top and bottom edges of the closure seal are provided to allow the bracket arms 26, 28 to extend therethrough. The surface of the rear edge of each panel inwardly of its groove 128 is slightly inset as at 134 to accommodate the thickness of the back .130 is the closure seal 124 so as to preclude any gap between the rear edge of the panels and the wall 14.

FIG. 9 illustrates .a modified construction of angle bracket supports for the partition panels 220 240, wherein conventional angle bars are employed. Thus, the angle 'bars 140, a both at the top and bottom of the panels, have their vertical legs 142 each positioned within a groove 144 formed within the inner side of each of the opposed panels and with the groove in panel 22c vertically offset with relation to the other, the vertical legs being secured in place by screws 146. The horizontal leg 148 of angle bar 140 overlaps the horizontal leg 148a of the opposed angle bar 140a which latter seats on the horizontal edge of an associate-d bracket arm (the upper bracket arm 26 being illustrated). Longitudinally spaced screws 150 extend through elongated openings (similar to 80a) in the horizontal legs 148, 148a to secure the same to the bracket anrns. To conceal the angle bracket supports 140, 140a, an edging filler strip 112a is positioned and secured in place bet-ween the panels similar to edging filler strip 112. In all other respects, the partition a is similar in construction to the partition 10, FIG. 2.

The partition 10 may also be pre-assembled and mounted as a unit on the bracket arms 26, 28. In this case, in lieu of the angle support brackets 30, 32, the panels 22d, 24d of partition 1%, see FIG. 10, are interconnected along their upper and lower edge portions by a channel bracket support 150 (only the upper channel support being shown). The channel bracket support 150 has its flanges 152 directed outwardly and secured by screws 154 to the inner opposed sides of the panels to rigidly connect the same in spaced relation, the width of the channel bracket support being equal to the thickness of the bracket arm 26. In all other respects the preassembled partition 10b is structurally similar to the partition 10, FIG. 2, except that it is mounted as a unit on the bracket arms 26, 28 by sliding the same thereon towards Wall 14, the web 156 of each channel bracket support engaging the horizontal edge of an associated bracket arm. The panel 10b is secured in position on the bracket arms 26, 28 by longitudinally spaced screws 158 extending through elongated openings in the webs 156 of the channel bracket supports for threaded engagement Within threaded openings in said bracket arms. The stile 12 is then mounted in position on the partition 10b in the same manner as described above. An edging filler strip M212 is then applied to the upper and lower open edges of the partition 10b to conceal the channel bracket supports as well as to finish said edges. In the form shown in FIG. 10, the side edges of the filler strip 112]: are beveled as at 160 to mate with complemental beveled edges 162 of panels 22d, 24d and the lower side and bottom portion of the filler strip 112b are groo'ved and recessed as at 164, 166 to accommodate the heads of screws 158, 154. The filler strip 1121) is secured in place by an epoxy or other suitable adhesive.

FIG. 11 illustrates a pre-assembled partition unit 100 embodying Formica coated panels 22c, 24:: connected together by upper and lower channel bracket supports 150 (as in FIG. 10) which at their forward ends have mitered engagement with the mitered ends of a vertical channel bracket support 170 secured to the inside [front edge portions of opposed panels 22e, 24a. Fitted within each Of the upper and lower corners defined by the channel bracket supports 158, 170 is a corner wood brace block 172 secured adhesively and by screws 174 to the inner side of panel 24:2. The corner brace blocks 172 are also adhesively secured to the inner side of panel 22a. Screws 176 also secure adjacent ends of channel support bracket 1'50, 170 to corner brace block 172 thus making for a corner construction of great strength. At the front vertical center portion of the panel 100 there is provided a dowel block construction 178 similar to 68, 70 of FIG. 2 or 86a of FIG. 8 for the connecting dowels or dowel 106 or 106a of stile 12. In this embodiment a front edge filler strip 180 is positioned in the channel bracket support 170 and secured in place adhesively and by screws 182, each end of the filler strip 180 terminating short of the corresponding end of the vertical channel bracket support 170 to provide a recess 183 for a purpose to be hereinafter described. Each corner brace block 172 is provided with a horizontal bore 184 coaxial with an opening 185 provided in Web of channel bracket support 170. The partition 100, in all other respects, is constructionally similar to the partition of 'FIG. 2. The partition 10c thus provides a unit handled construction adaptable tfor application and mounting on bracket arms that extend only partly into the partition and of shorter length than those shown in FIG. 2, and as illustrated by upper bracket arm 26d. Each short bracket arm is provided with a threaded bore 188 having its outer end flared as at 190. With the partition 10c slid as a unit onto the bracket arms, in the manner as hereinabove described with reference to partition 1%, a rod 194 having a threaded end portion 196 and a bolt head 198 at its other end is passed through the bore 184 in each corner brace block 172 with its threaded end 196 threadedlyengaging within threaded bore 188 in its associated bracket arm and its bolt head 198 seated in recess 183. The threaded rods 194 thus pull the partition 10!: tight up against wall 14 and will thereby hold the partition 10c securely on its supporting bracket arms as will be readily apparent. If desired a screw 200 at the rear end of the top and bottom channel bracket supports 150 is provided to secure the same to its associated bracket arm.

So mounted and secured to the bracket arms, the partition then has attached thereto the stile 12a in the manner as hereinabove described, the stile support arm 94 (only the upper being shown) seating on web of channel bracket support and secured thereto and to the corner brace block by a screw 202; the dowel 106 being also secured in dowel block 178. To finish the partition 100, an edging filler strip 1120 is applied to each of the upper and lower open edges of the partition 10c in the manner as hereinabove described.

In FIGS. 12 to 15, inclusive, there is illustrated one embodiment of a cantilever wedge-shaped partition of the general external form as shown in the patent to Nathan Schooler, No. 2,865,476 granted December 23, 1958, utilizing upper and lower cantilever bracket arms connected to a pedestal structure as illustrated and describe-d in the above referred to copending application of Nathan Schooler, Serial No. 350,629, filed February 25, 1964.

In FIGS. 12 and 13, the wall 220 and floor 222 contains the above referred to pedestal structure (not shown) which carries, as shown in FIG. 13, upper and lower projecting cantilever bracket arms 226 and 228. Each bracket arm comprises a vertical plate member 230 having a horizontal edge portion 232, normal to the wall, on which is symmetrically positioned and rigidly secured as by welding a wedge-shaped support plate 234. The vertical plate member 230 of each bracket arm tapers towards its forward terminal end 236, with the inclined edge 238 of one in opposed relation to the inclined edge 238 of the other. The forward end 240 of the support plate is inwardly of the end 236 of the vertical plate to provide a seat 242 for a stile support arm as will be hereinafter described.

The cantilever wedge shaped partition 250 comprises two For-mica coated panels 252, 254 similar to panels 22, 24 of FIG. 1 and are assembled on the job to form the partition. Thus, each panel has secured to the inner side thereof upper and lower angle bracket supports 256, 258. The vertical leg 260, see FIG. 13A of each angle bracket support is directed respectively to an adjacent horizontal upper and lower edge of the panel, and is secured thereto by spaced screws 262 such that the horizontal legs 264 thereof are opposed to each other, parallel and spaced apart a distance equal to the distance between the horizontal edges 232 of the bracket arms for seating engagement thereon as will be hereinafter described.

A wood or ply-wood vertical support 268 is secured by screws 270 to the center portion of the inner face of panel v254, the vertical support 268 being provided with a horizontal dovetail groove 272, see FIG. 15. A

Wedge-shaped lateral brace 274 of wood or ply-wood is provided along a portion of one side edge thereof with a dove-tail tongue 276 that extends from the wide rear end 275 to a shoulder or stop 278. The forward end 300 of the lateral brace 274 terminates in the plane of the front vertical edges of the panels 252, 254, and the lateral brace 274 is of a wedge-shaped corresponding to the bracket arm support plate 234. The lateral brace 274 when attached to the vertical support 268 is secured thereto and at its forward portion to the inner side of panel 254 by an epoxy or other suitable adhesive. The opposite side edge of the lateral brace 274 is provided with a mortise 304 intermediate the ends thereof. Provided in the forward end of the lateral brace 274 is a dowel receiving opening 306. Appropriately positioned and secured by a dove-tail groove 308 and tongue 310 connection to the inner side of the opposite panel 252 is a tenon 312 of a length somewhat less than the length of the mortise 304. The dovetail groove 308 extends inwardly from the front edge of the panel 252 so as to permit attachment of the tenon 312 to the panel.

A wall engaging closure board of wood or ply-wood 316 having a flange 318 along its outer vertical edge is secured both by an adhesive and by screws 320 to the inner side of the panel 254 so that the rear side of the closure board will be flush with the rear edge of the panel, see FIG. 14. A similar closure board 316a is provided for the other panel 252 but is not secured thereto, the closure board 3 16a having in the flange 318a thereof vertically space-d dowel-receiving openings 322.

The closure boards 31'6, 316a are of a length corresponding to the vertical distance between the support plates 234 of the bracket arms. Positioned on the inner side of panel 252 adjacent its rear edge are correspondingly vertically spaced dowels 324.

In the vertical plate 230 of each bracket arm is an opening 328 for receiving therethrough a bar 330 having at each end a threaded hole in which is threadedly engaged a set screw 332 provided with a lock nut 334.

In the assembly of the panels 252, 254 on the bracket arms, the panel 254 is first positioned thereon with the horizonal legs 264 of upper and lower angle bracket supports 256, 258 seated respectively on the upper and lower bracket support plates 234 and with its attached closure board 316 abutting the wall 220. It will be noted that the lateral brace' 274 carried by panel 254 is horizontally centrally positioned between the bracket arms, see FIG. 13, and that the closure board 316 will fit between the support plates 234 of the bracket arms and abut the wall 220. Screws 338 secure the horizontal lelgs 264 of the angle support brackets 256, 258 to the support plates 234 and thus serve to rigidly connect the panel 254 to the bracket arms.

Prior to installation of the panel 254, the rear side of closure board 316 may be coated with an epoxy or other adhesive for securing the same to the wall 220. Whether or not an adhesive is employed the set screws 332, after the panel 254 is placed in position, may be adjusted to clamp the closure board 316 to the wall 220 to insure a tight engagement therewith as will be apparent. A thrust plate 336 may be positioned between the set screw 332 and the closure board 316, and the set screw is locked in position by the lock nut 334. The other closure board 316a is then placed in position, and clamped into tight engagement with the wall 220 by the set screws 33-2. The closure board 316a may or may not be adhesively secured to the wall 220, as indicated above with reference to closure board 316.

With the panel 254 thus secured in place, the opposed. panel 252 is then similarly mounted on the bracket arms by the seating engagement of the upper and lower horizontal legs 264 respectively on the upper and lower support plates 234, with the simultaneous insertion of dowels 324 into dowel openings 322 and the tenon 312 into mortise 304 in lateral brace 274, the parts of said joints being secured together by an epoxy or other adhesive in the manner Well known. Also the abutting surfaces between the inner side of panel 252 and the closure board 316a and lateral brace 274 are similarly adhesively secured. Screws 338a securely connect the upper and lower horizontal legs 264 of angle support brackets 256, 258, respectively to the support plates 234 of the bracket arms.

A stile 340 whose exterior surfaces are Formica coated (similarly to stile 12) is provided with upper and lower support arms 342, 344 and a center dowel 346. The stile 340 in its attachment to the panels 252, 254 has its support arms 342, 344 respectively seated on the ledges 242 of the bracket arms, see FIG. 13, and secured thereto by screws 350; the dowel 346 being adhesively secured in dowel opening 306. The front edges of the panels 252, 254 may be secured to the rear side of stile 340 by an epoxy or other adhesive. If desired the open front end of the connected panels 252, 254 between lateral brace 274 and the bracket arms may be adhesively joined by upper and lower vertical closure strips 352, 356, the outer surface of which lie flush with the front ends of the panels and which may also be adhesively secured to the abutting rear side of the stile 340.

With the stile 340 secured in place, the open top and bottom sides of the wedge-shaped partition are closed by Wedge-shaped filler strips 358, 360 that are secured to the bracket arm support plates 234 by screws 362. At the narrow forward end of each filler strip 358, 360, a screw 364 extends through an opening 366 in the adjacent stile support arm in threaded engagement with an aligned threaded opening 368 in the end portion of the adjacent bracket arm, see FIG. 13. If desired, the side edges of the filler strips may be adhesively secured to the inner side edge portions of the panels 252, 254.

The on-the-job assembly of the Formica covered panels 252, 254 with Formica covered stile 340 on the bracket arms 226, 228 will provide a cantilever partition of great strength and rigidity without any visible fastening means; and further in view of the attractive appearance of the Formica coating, the partition will have exceptional beauty and appeal.

In FIGS. 16 to 19 inclusive there is illustrated a preassembled cantilever wedge-shaped partition unit 380 that is formed of Formica coated panels 382, 384. The partition unit 380 is designed for mounting on bracket arms 386, 388 that extend only part way into the partition, and similar to the bracket arms 26d employed in the embodiment of FIG. 11, though it is equally as well applicable to the bracket arms 26, 28 of FIG. 2. It is to be noted that the bracket arms 386, 388 do not include the wedge-shaped support plates 234 of FIGS. 12, 13.

In this embodiment, FIGS. 16 to 19, the panels 382, 384 are connected in opposed inclined relation to provide the wedge-shape by upper and lower parallel wedgeshaped channel bracket supports 390, 392, the side flanges 394 of which are directed. respectively to the upper and lower edges of the panels, see FIGS 18, 19, and secured thereto by screws 396. The channel bracket support 392 is formed of heavy gauge sheet metal and the channel webs 398 are spaced apart a distance equal to the distance between the horizontal edges of the bracket arms. Provided on the inner side of each channel web 398 are a pair of parallel angle bars 400, spaced apart a distance equal to the thickness of the bracket arms, and serving as a guide for positioning the partition 380 on the bracket arms and for preventing lateral movement thereof. The channel bracket supports 3-90, 392 preferably extend the full length of the panels from front to rear edge thereof.

Provided interiorly at the front end of the partition 380 is a vertical wood filler strip 402 that is secured to the inner sides of the panels 382, 384 by an epoxy or other adhesive and in addition, if desired, by fastener elements such as screws (not shown), the front face 404 of the filler strip lying flush with the forward edges of the panels, see FIG. 17. The upper and lower ends of the vertical filler strip 402 are each engaged by the terminal forward end of an adjacent web 398 of a channelbracket .support which is secured thereto by a screw 406. The vertical filler strip is provided adjacent each end with a horizontal bore 408 having an enlarged recess 410 at its outer end for a purpose to be hereinafter described. Also provided in the filler strip 402 are vertically spaced dowel receiving openings 412, at least one lying in the vertical center of the filler strip.

The rear open end of the partition is provided with a rear closure strip 414 suitably secured to the inner side rear edge portion of the panels and with its rear side lying flush with the rear vertical edges of the panel for abutting engagement with wall 220. Olt-out port1ons or slots 416 are provided in the rear closure strip 414 to accommodate the bracket arms 386, 388, see FIG. 18. The panels 382, 384 are interiorly braced against lateral deflection by upper and lower horizontal wedge-shaped braces 418, 420, and an intermediate vertical brace 422, all of which are rigidly secured to each other and to the inner sides of the panels in any suitable manner as by an adhesive and fastener elements in the manner Well known.

Provided in each of the open top and bottom edges of the partition 380 are edging filler strips 426, 428, secured in place by screws 430, see FIG. 19, which threadedly extend through the channel bracket web and guide angle bars 400. The side edges of the filler strips 426, 428 are grooved as at 432 to accommodate the heads of screws 396. If desired, the edging filler strips may be additionally secured by an epoxy or other suitable adhesive both to the inner side edge portions of the panels and to the channel bracket web 398.

Thus constructed, the cantilever wedge-shaped partition 380 is mounted as a unit on the bracket arms 386, 388 by sliding the same thereon, the horizontal edge portions of the bracket arms being received Within the guide angle bars 400 whereby the partition is properly positioned. A rod 436 similar to rod 194, FIG. 11, having a threaded end 438 and a bolt head 440 is inserted through each bore 408 in the vertical filler strip 402 with its threaded end extending into a threaded opening 442 provided in the end of each associated bracket arm and having a flared entrance 444, the head 440 of the rod being seated in recess 410. By setting up on the rods 436, the rear edges of the panels and the rear side of closure strip 414 will tightly engage the surface of wall 220. If desired, the rear edges of the panels and the rear side of the closure strip may be secured to the wall by an epoxy or other suitable adhesive.

A Formica coated stile 450 is provided with vertically spaced dowels 452. At each end of stile 450 is a stile support arm 454 that seats within a complemental recess provided therefor in the outer side of each filler strip 426, see FIG. 16, and is secured thereto by a screw 456 which further functions to secure the front end of the associated filler strip in position. The dowels 452 each fit within a corresponding dowel opening 412, and the stile 450 with the dowels 452 are respectively secured to the front edges of the panels, to the front face 404 of vertical filler strip 402, and to the dowel openings 412 by an epoxy or other suitable adhesive. The described attachment of stile 450 to the partition unit 380 is of great strength and rigidity. If desired, a screw 458 extending through the rear end of each filler strip 426, 428 and through the web 398 of each channel bracket support 390, 392 into threaded engagement with a threaded opening 460 in the associated bracket arm functions additionally to secure the partition unit to the bracket arms.

In lieu of the Wood edging filler strips 426, 428 employed in the partition unit 380, there may be utilized a sheet metal closure plate 470, as shown in FIG. 21. The closure plate 470 is of wedge-shape and complemental to the dimensions of the space defined by the opposed panels 382, 384 from front to rear, and is provided along each longitudinal edge thereof with a flanged bead 472 adopted to seat, respectively, on the upper edges of the flanges 394 of the channel bracket supports 3'90, 392 (only 390 being shown). The closure plate 470 is preferably transversely bowed as shown by the dotted line 474, and is provided with longitudinally spaced screw receiver openings 476. A spacer sleeve 478 is arranged in axial registry with all or selected ones of the openings 476, and a screw 480 extends through each opening 476 and spacer sleeve 478 for threaded engagement with a corresponding threaded opening 482 in the bracket arm. Setting up on the screws 480 will deflect the closure plate 470 into flat position to cause the flanged beads 472 to tightly grip the inner sides of the panels. If desired, the spacer sleeves may be welded or otherwise secured to the inner side of the closure plate or to the web of the channel bracket support.

FIG. 22 illustrates a modified construction for mounting the stile support arms of a stile 490 on a partition unit such as 380 embodying the metal closure plate 470 and showing only the upper end of the stile, it being under stood that the lower end of the stile has the same construction. Thus, the stile 490 has secured to the inner side thereof 'by screws 492, the vertical leg 494 of a stile support arm 496. The vertical filler strip 402a is provided on its front face at its upper end with a vertical recess 498 to receive the vertical leg 494. Positioned on the top end of the filler strip 402a is an anchor member 500 of inverted U-shape, the front leg 502 with bight portion 504 being respectively seated within complemental recesses 506, 508 formed in the top and front of the filler strip. The opposed rear leg 510 engages the inner rear side of the filler strip. Screws 512 and 514 secure the anchor member 500 to the filler strip. Formed in the bight portion 504 are spaced threaded openings 516. Similar spaced screw receiving openings 518 are provided in the stile support arm 496. Corresponding openings 519 are pro vided in the web 398 of the channel support bracket 390. At the foremost end portion of the stile support arm adjaoent the inner face of stile 490 there is provided a threaded opening 520.

Thus, in attaching the stile 490 to the front end of the partition unit 380, the stile support arm 496 will seat on the front end of web 398 of the channel support bracket 390 with its openings 518 in registry with web openings 519 and threaded openings 516 in the anchor member. Screws 524 engaged in said openings secure the stile support arm 496 in locked immovable relation to the filler strip 402a and the panels of the partition unit. The forward end of closure plate 470 is provided with a countersunk opening 526. A screw 528 extending through said opening and into threaded opening 520 securely holds the front end of the closure plate 470 in position. It is apparent that the above described modified construction for attaching a stile may utilize Wood edging filler strips such as 426, 428 of FIG. 16, recessed on their inner sides at the front to accommodate the stile support arm 496, in lieu of the metal closure plates 470.

Due to the rigidity of the Formica coated panels, their sound deadening properties and the internal lateral bracmg therein the partition units need not include therein the corrugated board or other filler as customarily employed in metal panel construction. However, such fillers may be placed within the hollow interior of the panels as herein described, if the use of such be deemed desirable.

While several embodiments of the invention have been specifically shown and described herein, it will be apparent to those skilled in the art that various changes and modifications in the details of construction, arrangement of parts and general application of the invention may be made with-out departing from the spirit and scope of the invention, as set forth in the appended claims.
