1 Claim.

The. object ofthe present/invention is to provide an inexpensive, strong and serviceable extension table of a special'type, in which a central frame is supported by a pedestal arrangement which"may-consist of leg members, the frame including longitudinal and parallel frame bars which-are held in fixedposition during the extension and retraction of table top members, in combination with two extensible table top members,each carried by a pair of metal slides which engage metallic angle bars secured to the pedestalframe and forming part thereof. Extension top members conceal, when they are closed, two

transversely extending extension leaf sections, each section carrying a skirt to conform with the skirted margin of the primary leaves of the table, and the two extension leaves being so associated with opposed cam plates carried by the pedestal as to'b'e reversely movable to upper position in line with'the primary table top members or to lower position below said members, at will.

The invention will be described with reference to the accompanying drawings, in which Fig. 1 is a plan view of a table in closed positionand embodying one form of the invention;

ward movement it will lie in the same horizontal plane as the first mentioned extension leaf section;

Fig. 6 is anisometric view of the first form of the structure in it position as shown in Fig. 4;

Fig. 7 is a view similar to Fig. 6 showing the elements in the position of Fig.

Fig. 8 is a top plan view of the first form of the invention showing the primary leaf supportingmembers .which slide directly thereon;

'Fig. 9is a bottom view of a second modified form of the invention showing the primary leaf members in spaced-apart open position preparatory to moving the extension leaf sections into operative position;

Fig. 10 is a bottom plan view of the modification of Fig. 9 but showing the primary leaf members in closed position; and

Fig 11 is a vertical sectional view taken on the line |l-|| in Fig. 10.

Referring to the drawings, I have shown, particularly in Figs. 1 to 3 inclusive, a first form of the invention comprising a table consisting of the primary leaf members I, Ix, and extension sections 2, 2x. The table is supported by a pedestal, which, in the present embodiment, consists of fourlegs 3 (two being shown in the drawing at 2) 'and thelegsi may be rigidly connected pose.

(Cl.c311--48) by cross tubing or bars 4. Thetop of the pedestal-is a frame assembly consisting of the parallel and longitudinally'extending angle bars 5, and the transverselyextending connecting bars 6.

The connecting bars '6 (hereinafter termed cam bars) are each formed with a lower cam slot Tand an upper cam slot 8, as to each cam bar 6. The lowercamslot receives the stud (indicated bydotted'lines) 9 of a'bracket arm It attached to the lower base of extension leaf section 2. The cam slot 8 of each cam bar 6 receives the stud l2 'of a bracket I3 secured to the under face of extension leaf section 21:.

Each primary table top member is secured to the opposed angle slide bars H, which, as shown particularly in Figs. 4 and 5, are inter-hooked with the bars 5 *so as to slide thereon. When the sliding movement is'continued to the position of Figs. 6 and Atheextension leafsections are "exposed.

When the primary table top or' leaf members are'in closed position,the sectional leaves 2 and 2m willbe' concealed, their position being as shown inFig. '4. 'In suchposition they are supported by brackets or studs, as described above, and also bylsupporting brackets l5, as shown in Fig. 4. In "the first movement, in order to raise and extend the extension leaf sections, section 23: is raised and moved'outwardly from the position of Fig. land Fig. 5. Thereupon the extension leaf section! is raised and moved outwardly, first to the position of Fig. 5, and then in continued outward. position untilthe leaf lies horizontally and in abutment with extension leaf 2r. In the complete outward movement of extension leaf section-'2, its inner edge is spaced from that of extension leaf section '23:. Therefore the cam slot .1, in each of the opposed cam bars 6, is formed with an inwardly directed and overhanging horizontal extension Ix. This enables extension leaf section 2- to be moved inwardly so that its studs will rest upon the horizontal lower wall of the overhanging slot area and. also the inner edge oflleaf section 2 will abut that of leaf section 2x. It will be noted that the parallel angular frame members-5 arereinforced by transversely extendingrigid connector members I8 and the table legs may besecured directly to member It as by bolts throughthe apertures indicated I9. Primarytable top members may be secured by screws or other fastening devices directly to the slides -l I, whichare apertured. as at2ll for such pur- Also, as indicated in the drawings, the transverse margins of the primary table top members may be provided with pins and sockets,

the sockets being indicated at 2| and the pins at-ZZ-fOrinter-engagement with themselves and .also with'theextension leaves which are likewise be employed.

:Referringnowto Figs. 9 to 11 inclusive, whereangle bars 33, 34.

in is shown a modified form of the invention, the reference numeral 3| indicates generally a rectangular frame comprising two spaced horizontal members 32, 32. Rigidly secured to the members 32, 32' are a pair of transverse horizontal As best shown in Fig. 11, the angle bars 33, 34 are each formed with a downwardly depending portion 33', 34 and a horizontally-extending flange portion 33", 34" respectively. A horizontally-extending brace member 35 is secured at its opposite ends to the lower portions of the downwardly depending sections 33', 34' and a pair of supporting brackets 36 (only one being visible in the drawing), similar to the supporting brackets described above with respect to the first modification, are secured at their opposite ends to the members 33, 34. It will thus be seen that the members 32, 32', bars 33, 34, and brace elements 35, 36 together comprise a rigid rectangular frame 3|.

The reference numerals 38, 39 indicate two primary table top sections. A pair of spaced horizontal slide members 40, 4| are secured at their left-hand ends to the undersurface of the table top section 38 by means of the screws 42 or other suitable means. The opposite ends of the slides 40, 4| project outwardly beyond the straight side edge 42 of the table top section 38. A second pair of slides 43, 44 are secured at their right-hand ends to the undersurface of the table top section 39 and have opposite ends projecting from the table top section 39 toward the table top section 38. The slides 40, 4|, 43, 44 are slidably mounted with respect to the members 32, 32' of the frame 3| in the same manner as described above with respect to the first modification. The ends of the bars 33, 34 are provided with slots 46 through which rivets 41 extend. The ends of the rivets 41 are secured to the slides 40, 4|. It will thus be seen that the frame 3| is slidably mounted with respect to the slides 40, 4| for limited movement in a direction parallel to the slots 46 and team extent limited by lengths of the slots 46.

The downwardly depending sections 33' 34' of the angle or cam bars 33, 34 are provided with a cam slot arrangement adapted to slidably and rotatably support the extension leaf sections 49, 50. The latter are provided with brackets 5|, 52 having studs slidably mounted within the cam slots in the same manner as described above with respect to the first modification. Adjacent the straight edge 54 of the table top section 39 and on the undersurface thereof are mounted a pair of stop members 55, 56 having downwardly depending lugs 51. The lugs 51 are adapted to abut against the upper inner surface 341: of the vertically-extending section 34.

The operation of this second modification will now be briefly described: In Fig. the table is shown in the closed position with the table top sections 38, 39 abutting at their respective straight edges 42, 54. To open or extend the table, the section 39 is grasped and moved outwardly to the right as viewed in the drawing. This will cause the slides 43, 44 to slide relative to the frame 3| and the slides 40, 4|. When the table top section 39 and the slides 43, 44 approach the outermost position shown in Fig. 9, the lugs 5'! of the stop members 55, 56' will abut against the upper inner surface 34a: of the angle bar 34 so as to move the entire frame 3| to the right along with the table top section 39 until the left-hand ends of the slots 46 abut against the bolts 41, as shown in Fig. 9. The leaf extension sections 49, 50 may then be moved outwardly and upwardly into operating position in the same manner as described above with respect to the first modification. It will be noted that the pins 58 on the left-hand edges of the leaf extensions 49, 50 will then be spaced from the straight edge 42 of the table top section 38. Similarly the pins 59 of the table top section 39 will be spaced from the right-hand edges 60 of the leaf extension sections 49, 50. After the latter have been moved upwardly into operative position so as to be in alignment with the table top sections 38, 39, the table top section 39 is then moved to the left so as to cause the pins 58 to enter sockets (not shown) provided in the straight edge 42 of the table top section 38, and also to cause the pins 59 to enter sockets provided in the right-hand edges 69 of the leaf extension sections 49, 50. The table structure will then be in completely assembled operative arrangement.

It will thus be seen that by the suitable location of the stop members 55, 56 and also the slots 46 and bolts 41, the proper spacing between the table top sections 38, 39 and the leaf extension sections 49, 50 is provided automatically by merely one simple outward movement of the table top section 39. After this spacing has been obtained and the leaf extensions moved to operative position, the table top sections 38, 39 and the leaf extensions 49, 50 may be quickly brought together into assembled abutting relation by merely sliding the table top section 39 a short distance to the left toward the table top section 38.

It will be understood that various modifications may be made in the form of arrangement of the elements constituting the embodiments herein shown and described without departing from the spirit of the invention, what I claim and desire to secure by a patent being as follows:

In extension tables the combination comprising a pair of spaced members and a pair of spaced bars secured to said members and extending transversely thereof so as to form a rigid rectangular frame, two pairs of spaced slides on and adapted to co-act with said members by sliding movement, each pair of said slides supporting a horizontal table top section, a pair of sectional leaf members, cam means for slidably and pivotally supporting said leaf members on said bars, means for limiting the relative sliding movement of the frame with respect to a first pair of said slides, and stop means fixed with respect to the second pair of the slides and cooperable with the frame for moving the latter in a direction away from the table top section supported by said first pair of slides when the second pair of slides is moved outwardly in said direction.
