14 Claims.

This invention relate to windows of the swinging sash type. In a preferred form of the invention, it relates to pivoted sashes mounted in the frame by means of pivots located between the ends of the sash. A modified form of the invention includes windows having sashes mounted on pivots or hinges located adjacent one end or side of the sash.

It is an object of the invention to provide a window construction wherein standard sections may be used for the sash and frame and wherein standard sections of the sash and frame may be interchangeably adapted to engage each other from the inside and the outside of the window, depending upon the relation of the particular portion of the window to the pivot.

A further object of the invention is to provide a stay and a sliding shoe construction in which the shoe shall be mounted to slide in the sash member and provide frictional resistance to hold the window in open position.

A further object is to provide various novel shapes of frame and sash rail sections adapted to have resilient weather stripping mounted therein to insure sealing of the windows.

Referring to the drawings in detail and particularly to the construction shown in Figs. 1 through 13, a pivoted window is shown having a frame comprising header 20, sill 2i, jambs 22, A plurality of sashes may be mounted in the frame on pivots 25 which may suitably be secured in the frame in a manner to be described. The inward and outward movement of the sashes is controlled by the stays 26. It will be seen, that since the sashes are mounted on pivots, the portions of the sashes on either side of the pivot will open in opposite directions to the frame. Thus, in the form shown, referring particularly to Figs. 2 and 6, the upper portion of the sash is inwardly opening, while the lower' portion is outwardly opening. The engaging portions of sash and frame are accordingly so formed as to permit this method of window opening while insuring tight weather sealing relation.

The jambs, header, and sill are preferably formed of bars 21 of identical section which may be of any suitable material such as non-corrosive metal and may,if desired be extruded in one piece to the proper shape. For convenience the jamb member only, as shown in Fig. 4' will be described. This member comprises a base portion 28 having flanges 29 and 38 extending outwardly of the window opening, forming an outwardly facing channel, the outside flange 29 forming :a pocket for caulking 3|. The inner side of the base 28 has flanges 32 and 33 extending therefrom, each oi said flanges being set inwardly of the edges of the base 28. Intermediate said flanges 32 and 33 is situated a short rib 34. The outside flange 32 terminates in an inwardly turned lip 35 and the flange 33 has a lip 36, and offset portion 31, and a flange 38 terminating in a striking lip 48 which may suitably be of somewhat heavier gauge for strength and to provide a broader striking face.

Mounted in the frame member is a resilient V- shaped weather sealing member which may suitably be of non-corrosive metal or other suitable durable resilient material. One leg of the V comprises a base 45 which engages the lip 36 and the rib 34, the vertex 46 of the V being held under the lip 35. The other leg of the V, which is preferably somewhat longer than the base comprises a flexible tongue 41 which engages the sash in a manner to be described when the window is closed and is limited in outward movement and guarded from the ingress of dirt and moisture behind it by the striking lip 48 when the window is open. The overhanging striking lip 48 also protects the thin and flexible edge of the tongue from being injured or from causing injury. The jamb member shown in Fig. 4 is arranged to receive the outwardly opening or lower portion of the pivoted sash. To provide for the inwardly opening portion of the sash, it is only necessary to reverse the position of the flanges 32 and 33.

The jamb includes in addition to the member 21 a supporting angle 58, one leg i of which engages the base 28 of the member 21 while the other leg 52 extends laterally of the window into the building wall. In the particular construction shown. in Fig. 4 a plate 53 extends inwardly of the window from the leg 52 forming a reveal, having a guard 54 for plaster 55 and terminating in a plaster supporting flange 56. The angle iron 51 between the supporting angle and the reveal serves to insure rigidity of construction. The parts may be secured together by any convenient means and it will be understood that the interior finish described is merely optional and may be varied as circumstances may require.

The header comprising a bar 21 of the standard section may be suitably supported by an angle member 68, the member 68 being suitably secured to the lintel 62, which may be of steel or other suitable material. The member 68 includes a base portion 65 which engages the base 28 of the member 21, and a stepped portion 61 terminating in an upwardly extending flange 68. An inwardly extending reveal plate 69, having a plaster guard 18 terminating in a plaster supporting flange 'Il may be used in connection with the header.

The sill includes with the standard member 21 an angle 15, one leg 16 of which engages the base 28 of the frame member 21, the other leg 11 of which extends downwardly into the building wall, a member 18, having a portion extending inwardly of the window opening from the leg 11 of angle 15 forming a stool 19, the stool 18 having a downwardly extending portion 88, inset at 8| to provide a'securing point for attachment to the building wall by any suitable means such as screws 82. The angle 83 is attached to the angle 15 and the stool'and insures that the sill as a whole shall be rigid and strong. The angles 58, 68 and 15 which may be of steel or other strong metal are preferably welded together or otherwise united at the corners of the frame, so as to form a complete rigid outer frame or back. i

As can be seen from Figure 4, the standard frame member 21 may be directly applied to the mullion 24. Thus as many windows as are desired may be assembled in a single row in the field during application to a building without modification of the frame members. The mullion comprising a channel shaped member 85 has two lateral ofiset flanges 86 upon which are mounted the bases 28 of the members 21. The flanges at the inner edges of the member 21, extend to meet the channel member 85 and the flanges extending from the outside edges of the base. 28, may suitably be joined by the flller web 81 whereby a rigid hollow mullion is provided. The strength of the mullion may be determined according to-the height of the window by varying the depth of the inwardly extending channel 85 which is used to form the mullion.

The bottom sash rail (see Fig. 3) comprises a rectangularly shaped hollow member having pane engaging seat I88, at one side of which extends a flange I8I having an inward lip I82 at its edge adapted to engage the pane I83. At the other side of the seat I88 is an undercut flange I84 adapted to key with the putty and hold the same in place. To assist in holding the pane in place, a pane clip,

such as the clip I85 may be employed. The lip I82 has a definite use for glazing purposes; thus the recess formed by the base I88, the flange I8I and the lip I82 may first be filled with glazing compound I86, the pane I83 may then be set against the lip I82 and there will thus be a complete seal between the rail and the pane without exposing any part of the glazing compound I86 on the inside of the window. Furthermore the pane may be set exactly against the flange I82 and its position in the sash easily determined, without squeezing out all of the glazing compound on the inside of the pane as would happen in the case of a straight pane setting flange.

Extending from the pane seat in a direction away from the pane proper are the two side po'rtions I88 and I89 of the rectangular rail, which are joined near their ends by a web I I8 constituting the fourth side of the rectangle. Extending from the side I 88 is an offset downwardly extending flange III which terminates in an inwardly turned striking lip H2 adapted to strike against the outside of the flange 32 of the frame member when the window is closed. The end of the side I89 provides a striking flange I81 for engagement with the flexible tongue 41 of the weather strip and the outer surface of the side I89 provides a striking point for the striking lip 40 on the frame. Thus in the form described, the short striking flange I01 which engages the resilient tongue ll is seen to be on the insideof the sash, while the longer flange II I terminating in inwardly turned striking lip I I 2 is on the outside of the sash.

The top sash'rail is similar to the bottom rail, but reversed in position. It comprises a hollow member having a pane engaging flange I20, a putty retaining flange HI and long and short striking flanges I22 and I23. This rail differs from the bottom rail in that the long striking flange I22 is situated on the inside of the sash while the short striking flange I23 is situated on the outside thereof.

It is to be observed that where a plurality of sashes are mounted in a single frame one of the meeting rail sections I25 may be identical with the heretofore described top rail member, :the other of said meeting rail members comprising a rectangularly shaped hollow rail I30 having situated on the pane side thereof a pane engaging flange l3! terminating in an in-turned lip I32 adapted to engage the pane I03 and having on the opposite side of the rail an undercut putty retaining flange I33. The rail member also has a flange I35 terminating in an overhanging lip I36 and a longer downwardly extending offset flange I31 terminating in an inwardly turned lip I 38. Situated between the said flanges is a V-shaped resilient weather stripping member, one leg I40 of the V lying against the wall III of the rail, the vertex I42 being engaged beneath the lip I36 and the other leg I43 of the V comprising a resilient tongue which is engaged by striking flange I23 when the window is closed and limited in outward movement by the lip-i3l when the flange I23 moves out of engagement therewith.

Any suitable locking means may be provided to secure the meeting rails in tight relationship, such as the latch I which is described in our copending application Serial No. 243,935 filed December 5, 1938.

As heretofore described in connection with the lambs, the side rails of the sashes on either side of the pivot 25 must have oppositely disposed striking surfaces to provide for outward and inward opening of the sash on either side of the pivot. In Figures 9 through 12 this relation is particularly illustrated both for the jambs and the side rails. It is further seen that one of the side rail members may be identical with the above described top rail member, while the other is similar in cross section to the bottom rail member.

The result may be accomplished in the case of the rail by forming the sash rail section in one piece having flanges extending outwardly, upwardly and inwardly from either side thereof as indicated in Fig. 12 and then by removing one or the other flange as the case may be,

'or the result may be accomplished by splicing two portions of rail as shown in Fig. 12, the block I50 being preferably included to strengthen and support the splice. In the case of the jamb, a similar procedure may be used, except that where splicing is employed only one section need be provided, as by reversing this section the engaging and striking surfaces for the oppositely disposed sash are presented. It is again preferable to include supporting block I5I in the channel shaped backing of the lamb. As shown in Figs. 11 and 13, the striking flanges are cut I ment by means of the stay 26 (see Fig. 6).

application of the pivots and movement of the sash.

The pivots 25 upon which the sashes are mounted may preferably be located between the top and bottom of the sash or should it be desired to mount the sash to swing horizontally, the pivots will be located in the header and sill. As shown in Figs. 2, 6, 'I and 8 the sash is mounted to swing outwardly at the bottom and inwardly at the top about the pivots 25. Each pivot comprises a 'pin I55 rigidly mounted in the frame through the supporting block I5I and the jamb base 28. A bushing I56 is preferably rigidly mounted in the hollow sash rail. The pin may preferably be of steel or similar metal and will turn easily in the bushing. While it can be seen that advantage in opening and closing the window will accrue in locating the pivots so that the window is balanced as to upper and lower in-swinging and out-swinging portions, the pivots may, of course, be located in any convenient position.

The window may be limited in outward move- The stay is secured to the frame (see Figs. 5 and 6) by means of the block I60 to which it is pivotally attached by the screw I6I.

The stay is pivotally secured to a friction shoe I62 by means of a detachable screw I63, which may be of any convenient form to permit removal so that the window may be opened beyond the fully extended position of the stay.

The shoe I62 rides in the hollow sash rail and thus the sash rail acts as a part of the stay construction and eliminates the heretofore expensive necessity of making a separate item of the stay and mounting it on the sash.

The shoe I62 comprises a rectangularly shaped member having a notch I10 in one side thereof in which a leaf spring III is inserted. The spring I is adapted to bear against the side of the channel shaped rail member, the amount of the friction exerted between spring III and the side of the rail member being adjustable by the screw "2 which bears against it. A fiber block I13 is mounted in the shoe on the side opposite the spring to aid in making good fric tlonal contact between the shoe and the rail.

It will be observed referring to Figures 6 and 11 that the striking flange I01 which normally engages the flexible tongue 41 of the weather strip when the window is closed, is not present on the portion of the sash between the closed position of the brake shoe I62 and the end of the block I60. This is necessary to permit the stay to assume its position between the frame and the sash when the window is closed. However referring to Figure '7, it will be seen that the side of the stay 26, when in closed position, engages the tongue 41 so that there is sealing contact against the tongue for substantially the entire length of the frame.

Referringnow to Figs. 14 through 23, a modifled form of the invention is shown. This form includes, referring particularly to Fig. 14, a combination window having an upper transom panel 200, a central casement panel 20I, and a lower transom panel 202. In the upper transompanel 200 the sashes swing outwardly and upwardly, in the central panel 20I, the sashes swing outwardly on the side frame 205 and the mullions 206. In the lower transom panel 202 the sash swings inwardly and downwardly.

Referring particularly to Fig. 15, the upper transom panel includes bottom, top, and side rails which may be of identical cross section. This standard rail includes, referring to the top rail for convenience, a hollow rectangular por-.- tion 210 having a pane seating portion 2 on one side thereof with pane receiving and putty retaining flanges similar to those heretofore described. The hollow member 2I0 also includes an inside short upwardly extending flange 2l2 and a longer outside flange 2l3 which are adapted to engage striking surfaces on the header H4.

The header 2|4 includes a web 2l4a having two upwardly extending flanges H and N511, a flange 2l6 extending downwardly from the inside edge thereof terminating in an inwardly turned striking lip 2l1, which is adapted to strike against the flange 2l2 when the window is closed.

The flange 2l6 also has a shoulder 2l9 near the base thereof for a purpose to be described. Extending downwardly from the outside edge of the header member is a flange 220 having an inwardly turned lip 22I on the end thereof. Extending downwardly from the web 2l4a intermediate said flanges is a rib 222. Entrapped in the said header member is a resilient V-shaped weather sealing member, one leg of which rests on the shoulder 2H! and the rib 222, the vertex 'with the resilient tongue 223 and the engagement between the lip 2H and the side of the flange 2l2 results in a three point weather sealing engagement.

The header member is held in position in the frame by the stepped angle member 225 which is secured by any suitable means to the lintel 226. A plaster guard 221 may also be provided and may suitably be secured to the angle member The drip flange 220 may be suitably secured to the angle member 225 and form with the lintel 226 a pocket for caulking 220.

As shown in Fig. 22 the upper transom 200 may suitably be movable in the frame on the hinges 230 which have stationary leaves 23! secured to the top of the frame and movable leaves 232 secured to the top of the sash rail. The outward movement of the upper transom may preferably .be limited by stays 234, which are suitably controlled by friction shoes 235, which may be similar in construction to the shoes heretofore described in connection with the preferred form of the invention.

The transom .bar 204 includes a shaped member comparable to two of the header members, heretofore described, placed back to. back with the flange 2l5a removed, the flanges 2| 5 being and between the base portions of the sash engagingparts 'of the transom'bar may be situated a steel or other heavy reinforced member 243,

sashes of the panel 20l include a standard sash member 405 comparable to the rail 2l0 heretofore described, having striking flanges 406 and 401. The rail 408 which meets the rail 405 includes a hollow rectangular portion having pane engaging means on one side thereof and having extending from the inside edge of the opposite side a flange 4l0 terminating in a striking lip 4| l, and a flange 2 extending from the outside edge thereof having an inturned undercut portion 3. Intermediate the flanges M0 and H2 are situated flanges H5 and H6. A V-shaped resilient weather stripping member is mounted in the rail 408, one leg of the V 420 resting on the fianges4l5 and 6, the vertex 42l of the V being engaged under the in-turned lip M3 and the other leg 422 of the V forming a freely moving tongue which is limited in outward movement when the window is open by the in-turne'd lip 4H and is engaged in sealing relation by the flange 401 on the rail 405 when the window is closed.

The upper and lower sash bars of the outwardly swinging sashes of the panel 20! as well as the side rails of the panel 20! and the bar 405 for the meeting rail are identical in cross section with the sash bars 244 and 245 and the side rails of the upper transom panel 200 above described. It can accordingly be understood that considerable saving in production cost may be achieved by providing such a standard part.

It further can be seen that the jamb member 210 is identical in cross section with the header 2 I4 and accordingly a single section may be utilized for both of these frame members. mullion 212 is observed to be identical with the transom bar 204 with the exception that depending upon the height of the sash the reinforcing bar 213 is broadened'to provide 'more support.

It is thus seen that in so far as the outwardly swinging panels are concerned whether they swing outwardly and upwardly or outwardly on hinges mounted upon the jambs, a single sash rail section is necessary, a single section for header and jamb and a single section for the mullion and transom bar.

The jambs of the inwardly opening transom 202 include a channel member 250 having inwardly extending short ribs 25l and 252, and an undercut flange 253. The jamb proper 254 has a short rib 263 and is adapt ed to interfit with the ribs 25l and 252 and the flange 253 of the member 250. The member 254 includes an outside flange 256 terminating in an inwardly turned striking lip 251 and a shorter flange terminating in an inwardly turned lip 258. A resilient metallic weather strip 259 is concealed in the jamb member with the which serves to strengthen and render the construction rigid.

The meeting rails of the outwardly swinging flexible tongue 260 engaging the flange 251 when the window is open and the flange 26I of the sash when the window is closed. The sash further includes a striking flange 262 and has pane receiving means as heretofore described.

The member 254 is adapted to .be joined with a channel shape mullion web 265 to form with a supporting portion, preferably of steel or other hard metal 266, a strong rigid mullion for central support.

The mullion 265 includes two parallel portions 215 and 216 joined by the web 211. The parallel portions are identical in cross section on either side of the web 211 and include short ribs 218 Y and 219 and an.undercut lip 280. The members 288 and 282 which are observed to be identical with the jamb 254 in cross section are adapted to interflt with either side of the mullion 299 in themanner previously described in connection with the jamb 254..

The top rail 285 of the inwardly opening transom panel includes a rectangularly shaped hollow, member havingpane engaging means similar to those heretofore described on the lower side thereof and having an inner upwardly extending flange 288 on the upper side.

The transom bar 289 which separates the upper bar 298 of the inwardly opening transom panel 292 and the lower bar 245 of the outwardly opening panel 29l comprises lower and upper channel members 299 and 28L The lower member includes a base portion 295 having a downwardly extending flange 299 adjacent the outer side thereof terminating in an inwardly turned lip 291 and having a short downwardly extending flange 299, an offset portion extending outwardly therefrom having a flange 299 terminating in an inwardly turned striking lip 399 adapted to strike against the side of the hollow rail 285. Intermediate the flanges 299 and 298 is situated a short rib 391. Mounted in the member 299 is a v-shaped resilient weather sealing member having a base portion 392 engaging the ends of the flanges 298 and 39l, the vertex 394 of the V being engaged under the in-turned lip 291 and the other leg of the V forming a flexible tongue 399 which is held from outward and downward movement by the inwardly turned lip 399 when the window is open, and which is engaged by the top portion of the rail 285 when the window is closed. Extending upwardly from the base portion 295 are short flanges 3I9 and 3, the flange 3 being slightly undercut on one side thereof.

The member 291 comprises a channel shaped portion having a base 3l5 and flanges 3l9 and 3H extending downwardly from either edge thereof. The flange 3|9 terminates in an inset dove-tailed groove 3l8 adapted to engage the undercut flange 3H and the flange 311 terminates in an inset groove 3l9 which engages the rib 3l9. It can be seen that a firm connection is thus achieved between the members 289 and 299. Extending upwardly from the inner edge of the base 3l5 is a flange 325 terminating in an inwardly turned striking lip 329 and having a shoulder 321 adjacent the base 3l5. Extending upwardly from the outer edge of base 3I5 is a flange 329 which terminates in an inwardly turned lip 329. Intermediate said flanges 325 and 329 is a short upwardly extending rib 339. A resilient V-shaped weather strip is mounted in the member 291 in the manner previously described in connection with the upper and lower rails of the outwardly extending sashes of the panels 299 and 291. The weather strip and the flanges 325 and 328 are adapted to be engaged by the striking surfaces ofthe lower rail member 245 of the outwardly swinging sash panels The inswinging panel 292 includes a lower sash rail comprising the hollow generally rectangular member 335 having upwardly extending pane engaging flanges as heretofore described and having a downwardly extending flange 339 slightly offset from the inner edge thereof and a downwardly extending flange 331 slightly offset from the outer edge thereof terminating a striking lip 338. Intermediate said flanges is situated a short downwardly extending rib 339 having an outwardly turned lip 349 at the edge thereof. A V-shaped resilient metallic weather strip is entrapped in said lower sash member, one leg of the V lying, against the horizontal portion of said member, the vertex of the v being held under the lip 349 and the other leg 3 of the v extending outwardly toward the inside of the flange 331. The leg or tongue 3 is limited in outward movement relative to the V by the striking flange 338 when the window is open.

The sill engaged by the lower sash rail above described includes a downwardly extending flange 345 which forms with the building wall 349 a pocket for caulking 349. Extending inwardly and upwardly from the flange 345 is the stepped portion 349 having the riser 359 against which adapted to be engaged on its outer side by the downwardly extending striking flange 339. The

sill may suitably be supported by angles 399 and stool 39l which may be suitably secured in rigid and strong relation by the small angle 392.

It will be observed that the jamb member 219 (see Fig. 16) may suitably be adapted to form the member 259 (see Fig. 17) which is used in connection with the in-swinging transom panel and further that the mullion 212 may be adapted Fig. 17.

bers may be constructed to receive outwardly in the same manner to provide seats for the adaptor members 28l and 282 as illustrated in It is further seen that the frame memswinging panels, but if desired an adjustment may be made in the field by shortening the flanges 2l9, 229, and 222 (see Fig. 15) and applying the adaptor members 254 thereto. In like manner the mullion 212 may be transformed into the mullion 295 and the frame thereupon is adapted to receive inwardly rather than outwardly swinging panels.

In Figs. 18 through 21, is shown a cremorne bolt which is especially adapted for use in connection with the window of this invention. The bolt includes (see Fig. 18) the identical shaft members 315 and 319 having bolt heads 311 and 318 at the ends thereof which are adapted to be inserted, when the bolt is actuated, in keepers 319 and 389 situated in blocks 382 and 383 which are held in the upper and lower frame members of the panel respectively'.' The shafts 315 and 316 are inserted in sockets 395 and 389 which are integral with the rack members 381 and 388 actuated by the pinion gear 399 which in turn will be rotated by movement of the handle 39l which extends from the panel on the inner side of the window. The entire bolt, rack and pinion mechanism may be situated in one of the hollow rails of a sash member and accordingly the mechanism is applicable to the meeting rail, having no mullion therebetween. The rack members slide directly against and are guided and held in position by surfaces of the extruded shape forming the meeting rail.

Further. to aid in looking the window a latch finger 499 mounted to rotate with the pinion 399 is provided, the end 49| of the finger being adapted to engage cam surface 492 and 493 of the keeper 494, the weather strip being cut away so as to fit against the ends of the keeper.

We claim:

1. A window frame member comprising a web having inside and outside outwardly directed flanges, an outside inwardly directed striking flange having a marginal lip, a longer inside inwardly directed flange having an outwardly directed striking lip, a shoulder formed near the base of said longer inside inwardly directed flange, and a short rib formed on said web between said inwardly directed outside and inside flanges, and a.
