WINDOW Filed Jan. 16, 1940 3 Sheets-Sheet 5 Patented Aug. 17, 1943 UNITED STATES PATENT OFFICE wmnow Edwin G. Bunjes, Lcs Angeles, Calif. Application January 16, 1940, Serial No. 314,063 7 '2 Claims. (Cl. 268-21) This invention relates to windows, and. more particularly to'windows comprising a plurality of with the screens if they open outwardly. One

of the objects of the present invention is to overcome these difficulties.

Heret'ofore, French windows have been-the only'type that could easily be cleaned on both sides by a person remaining entirely on the inside of the room, an advantage that has been offset by the above mentioned complications involving curtains, drapes and screens. An additional object of the present invention is to provide a window that may be as easily cleaned as theFrench type without any of the disadvantages associated therewith. 1

Other objects of the invention herein described, are the attainment of a decorative effect simulating that of Venetian blinds; the exclusion of rain and outside air; the provision of means for opening certain of the panes for ventilation or other purposes while leaving the remainder of the panes in closed position, and of means for opening and closing all of the panes by a single control. Still other objects will appear as the specification proceeds.

In each of the three species of my invention coveredby this specification, the window comprises a series of panes Al, A2, A3, A4, and A5, substantially as shown in Fig. l, the exact number of panes being a matter of choice or design. Each of these panes is supported by a holder 13. or B followed by other indicia, as indicated in Figs. 1, 2, 6, '7, 8 and 14. By means of shafts C that are integral with the holders, these panes I are pivoted in the frame D, in a manner to be more fully described.

When ventilation only is required, it may frequently not be desirable to open all the panes, and for this reason provisions have been made whereby the upper and lower panes may be opened independently of the rest; and another control is provided for opening these intermediate panes when the upper and lower ones are already open, or for opening or closing the entire group. One form of this operating mechanism comprises a series of arms El to E5, Fig. 3, connected respectively to shafts CI to C5. The upper and lower arms El and E5 are connected at the outer ends to rod F, and the on, shaft H, journaled in plates Ja and Jb of bracket J, attached to the under side of sill K by screws L. As indicated in Fig. 4, arm EG is freely rotatable on shaft H, while arm EF is at- A bevel gear tached to the shaft by pin MI.

NF is attached to shaft H by means of pin M2, and the hub O of this gear abuts against piece lb of the bracket. Bevel gear PF meshes with gear NF, and is attached by means of pin M3 in its hub 02 to shaft QF, carrying crank wheel RF on its outer end. Shaft QF is journaled in piece Jc of bracket J, and is additionally supported by escutcheon T2, fastened to the undersill S, through which said shaft passes. Longitudinal movement of shaft QF is prevented by hub 02 and collar Ul.

Through the instrumentality of the mechanism just described, it will be obvious that the upper and lower panes may be opened and closed by the operation of crank wheel RF. The rotation of this crank to the right causes gear PF to turn in the direction indicated by the arrow thereon, causing gear NF, Fig. 4, to turn toward the operator, thus raising the operating arm EF and, through link F, arms El and E5, which rotate shafts Cl and C5 in the direction required to open panes Al and A5. These sections of the window may, of course, be closed by turning crank RF to the left.

Gear N, which freely rotates on shaft H, functions to open panes A2, A3 and A4 if the upper and lower panes are already open, or to open and close them all. This gear is provided with an arcuate opening V, Figs. 3 and 5, extending from about 90 to 180 around the center. Pins WF and WG, attached respectively to operating arms EF and EG, both protrude into slot V, but they are positioned on these arms at different radial distances from the centers so that they may pass in slot V, which is wide enough to accerrr odate them both. As shown in Fig, 4, arms and EG are located on opposite sides of gear N, with washers X intervening. Gear N mwhes w th gear P, attached to shaft Q by means of pin M4 in hub O. The other end of shaft Q carries crank wheel R. This shaft is journaled in front piece Jc of bracket J, and is given additional support by escutcheon T, attached to under-sill S. Longitud nal movement of this shaft is prevented by its hub O and collar U3. Operating arm EG rotates arms C2, C3 and C4, through the linkage system previously expla ned.

Assuming that gear N is in the position shown in F g. 5. it will be obvious that arm EF, in opening the up er and lower panes. could have been turned to the pos tion indicated by means of the mechanism previously expla ned without imparting any motion to gear N, as pin WF. on arm had free space in sl t V in which to move. If crank R is now turned to the right, as indicated by the arrow, the associated gears will also turn in the directions indicated by the respective arrows. This movement of gear N w ll cause the lower edge Y of slot V to engage pin WG, thus raising arm EG and opening panes A2, A3 and A4, through the respectively associated arms C2, C3 and C4 and the interconnecting link G.

If it is now desired to close all the w ndows, crank R is turned in the opposite direction. As the upper edge Z of slot V will nowbe a considerable distance beyond pins WF and WG, crank R with the connected gears P and N must turn a considerable distance before the lost motion is taken up and pins WF and WG engaged. Edge Z will then press on these pins and move both arms EF and EG- to their downward positions, closing all the panes. At the end of this operation, pin WG will be in the position shown in Fig. 5, but pin WF will have been turned to a position beside pin WG, and edge Z of slot V will be in engagement with both pins.

Should it now be desired to open the ventilating panes, the rotation of crank RF will cause the connected parts to move arm EF upward. Inasmuch as pin WF will be in contact with upper edge Z of slot V, this upward movement of arm EF will cause gear N to turn, but no motion will be imparted to arm EG because the lower edge Y of the arcuate slot will be a considerable distance behind pin WG and will therefore not engage it.

If the mechanism was last used to close all the windows, and it is next desired to open them all, edge Z of the slot will be found in contact with pins or lugs WF and WG, and crank R must therefore be turned until edge Y moves around to the position of pins EF and WG before the operating arms EF and EG will start to move and to open the panes,

If the upper and lower panes are open and the remainder closed, the operating arms will be in the positions shown in Fig. 5, and the position of gear N will be as indicated or somewhere between this position and one in which edge Z would be in contact with pin WF. In any of these possible positions of gear N, it is obvious that the closing of the ventilating panes and the necessary downward movement of operating arm EF and the attached pin WF, will not cause any movement of gear N, as pin WF will have free space within the slot in which to move.

The species of operating mechanism shown in Figs. 9 and 10 may at first appear radically different from the species hereinbefore explained, but the following explanation will disclose that it embodies the same invention, as broadly defined in the appended claims.

Crank RF, Fig. 10, for operating the ventilating vanes, is attached to shaft QF journaled in sides Jo and Jg of the channel shaped member J, and constrained against longitudinal movement by collars UI and U5. This shaft bears pinion PF, meshing with rack NF, an integral part of rod F, mounted for longitudinal movement in horizontal pieces Jd and Je, supported in member J. Rod F bears another rack portion 8, meshing with pinion E5 carried on shaft C5, which operates the lower pane in the manner previously described and therefore not repeated here. The upper portion of rod F has another rack section like rack portion 8, for operating the upper pane through another pinion and shaft, but as these parts are duplicates of those just referred to, they are not shown in the drawings.

Crank R is attached to shaft Q, carrying pinion P, and prevented from moving longitudinally by collars U3 and U4. Pinion P meshes with rack portion 6 on rod N, which serves the same purpose as gear N in the species previously explained. Two spaced lugs, Y and Z, are mounted on one side of rod N. Tappets WF and WG are mounted respectively on rods F and G in such a manner that they enter the paths of lugs Y and Z so as to be engaged thereby upon longitudinal movement of rod N, which is slidably supported in pieces Jd and Je. Tappets WF and WG are adapted to pass each other without interference, as will be apparent from Fig. 10. Rod G is attached to rod Ga by an intermediate member Gb, jointed by bolts, screws or other appropriate means so that rods Ga and G move rectilinearly as a unit in the supports J 11 and Je. Rod Ga has a rack portion 1, meshing with pinion E4 on shaft C4, and other identical rack portions, not

shown in the drawings, are provided for other pinions that are similarly connected to the shafts that operate the other intermediate panes.

If the rods are in the position illustrated in the drawings, the upper and lower panes will be open and the intermediate panes closed. If crank R is now turned so that shaft "Q rotates in the direction indicated by the arrow around it, rod N will be moved upward through the action of pinion P on rack section 6, and lug Y, shown in engagement with tappet WG. will raise this tappet and thus move rods G and Ga. upward, opening the center group of panes through the instrumentalities of the various associated parts already described.

After the operation just mentioned, all the windows will be open and lug Y will be in contact with both tappets WF and WG. If it is now desired to close all the panes, crank R. is turned in the opposite direction, but no movement will be imparted to rods F and the integral GGa assembly until the lost motion is taken up between lug Z and the tappets. After they have been engaged, however, the further downward movement of rod N will cause the tappets to push their associated rods downward, thus closing the panes.

If the ventilating panes are open and the remainder closed, the operating rods will, of course, be in the position shown in the drawings. It will be obvious that the downward motion of rod F to close the ventilators will not cause any movement of rod N, because tappet WF will move through the open space between lugs Z and Y.

If the last operation of the mechanism was to close all the windows, tappet WG will be in the position shown in,the drawings, but tappet WF will be beside it, with lug Z in engagement with them both. Should it now be desired to open all the panes, the rotation of crank R. will cause rod N to move up until lug Y contacts tappets WF and WG without imparting any motion to the rest of the mechanism, but after the tappets have been engaged, the further upward movement of rod N will raise both tappets and the rods to which they are attached, thus opening all the windows through the operation of the various previously described interconnected parts.

The preferred form of my operating mechanism is that shown in Figs. 12, 13 and 14. In this embodiment, which resembles the species first described, bevel gear NF and operating arm' EFI, attached so that both turn as an integral unit, are mounted on shaft CI of lower pane A5. Bevel gear PF, Figs. 12 and 14, meshes with gear NF, and is attached to shaft QF journaled in pieces Jc2 and Jg2 of bracket J, the latter piece being adapted to receive the reduced end 9 of shaft QF, which passes through the trim, or window mold, piece ll) of frame D to carry crank wheel RF on its outer end.

Bevel gear N, Figs. 12 and 13, is free to rotate on shaft C3 of the middle pane holder, but it will be understood that shafts C2 or C4 would suffice as well. Operating arm EF3 is also free to rotate on this shaft. Rod F is attached to operatin arms EF and EF3, as well as to arm EFI, this last arm EF and connection not being shown in Fig. 11 because this part of the construction is identical to that pictured in Fig. 3. Operating arm EG is attached to shaft C3 by pin M5. Gear N has an arcuate slot V like that in the corresponding gear in Figs. 3, 4 and 5, and into this slot protrude the tappet pins WF and WG attached respectively to operating arms EF3 and EG. Link or rod G is attached to operating arm EG, which operates the intermediate panes in identically the same way as does rod G in the embodiment first described. The only difference in the operation of this third species of my operating mechanism and that of the first species, lies in the fact that the independent operation of the ventilating panes is controlled from a diflferent shaft than that which moves them in conjunction with the other, or intermediate, panes;

If the bracket J of Figs. 9 and 10 is of metal, the shafts c of the pane holders may be journaled directly in the bracket on the right side of the window. On the left side, independent bearings may be provided, or a strip of metal similar to II in Fig. 12 may be used to furnish bearings for all the shafts. In the first and third species, this last bearing means is preferred, because the bearing holes may be drilled in two such strips simultaneously from a template, and these may be mounted on the outer surfaces of the stiles of the window frame, as indicated in Figs. 12, 13 and 14, in which bearing strip II is shown attached by means of screws It to stile l2. The stiles are drilled to provide holes l4, Figs. 13 and 14, for each of the pane holder shafts, and each hole has a counter-sunk or enlarged portion l5 to receive the hub l6 of the associated pane holder, into which hub the shaft is rigidly attached by pin I! or other appropriate means.

The brackets J, Figs. 12, 13 and 14, are attached to the stile by screws l8.

Each side of the pane holders B is U-shaped or channeled, as indicated in Figs. 2, 8, 13 and 15, and in the form shown in Figs. 2 and 6, it consists of three integral sides |8, l9 and 20 into which the plate of glass may be slipped and cemented. .When the holders are four-sided, as in Figs. 7 and 8, it is necessary that the fourth side 2| be made in a separate piece so that the glass may be slipped into the three-sided portion l8, l9 and 20 and then the fourth side 2| slipped over the remaining edge of the pane. This fourth side can be cemented to the glass, and then, if desired, it may be soldered, welded or otherwise attached to sides I8 and 20. It is, of course, immaterial which three sides are made in one piece, and which becomes the fourth side.

When the holders are three-sided, they articulate as shown in Fig. 2, the upper unprotected edge 23 of each plate of glass fitting against portion 22 of the lower edge of side |9 of the adjoining pane-holder above. This construction prevents wind or rain from passing the joint.

When the holders are four-sided, the upper side 2| of the frame fits against the abutment 22 on side IQ of the holder next above.

If it is desired to provide a tighter fitting joint between adjacent pane holders, this may be accomplished by attaching a piece of spring metal to portion 22 of the lower side of the holder. This spring metal strip should have a cross section similar to that shown in Fig. 15, in which pane AI is shown partly opened, with strip 24 out of contact with edge 2| of the next lower pane holder. When the pane is closed, the spring strip presses tightly against edge 2| of the holder below, causing it to take substantially the shape indi cated on holder 3:12.

It is necessary that stops or a beading be provided to liimt the angular movement of the pane holders and to close the space that would otherwise exist between their outer edges and the adjoining stiles. The stops may be made of wood, rubber, or other material, such as a plastic. Molded rubber is perhaps the best. A stop 25, Fig. 2, is provided for the lower part of each pane holder, and another stop 21 for the upper part. These stops 25 and 21 have formed portions 26 and 28 respectively to fit around the hub l6. Beading or stops of the type just described is used on both the right and left stiles of the window, with a pair of stops for each end of each pane holder. A strip of heading or moulding 29 is attached to the upper portion of the window frame for the edge 23 of pane Al to fit against in the closed position, and another similar strip 30 is provided at the bottom to close the space that would otherwise exist between sill K and the lower side l9 of pane holder B5.
