TAYLOR, OE MONTREAL, QUEBEC, CANADA, ASSIGNOR TO THE ROBERT MITCHELL COMPANY LIMITED, 'OFJMONTREAL, QUEBEC, CANADA 'SASH GUIDE son wI Nnow rRAMrs Application filed May 26,

An object of the nvention is to provide a sash assembly including means for maintain ing the meeting rails of the upper and lower sashes in such tight engagement as to elimi-' nate the need of Weatherstripping at this point.

Anotherobjec't is to provide a metal sash assemblyin which the lower sash is mounted to slidein vertical Channels comprising upper and lowersections, the lower sections being displaceable with reference-to the upper sectionsto facilitate application and removal of the sash. c A further object is to provide a sash as-, sembly in which the sections of the lower sash guide are conveniently constructed of l sheet metal and attached to a common base 20 strip to provide aself-contained unit of inexpensive construction adapted to be readily applied to a window frame or removed therefrom. h I

' .Further objects and advantages of the invention, as well as the characteristic features of the embodiments herein disclosed will be 'more readily understoodlfrom the following detailed description taken in connection with the accompanying drawings, in which '30 Figure 1 is a side elevation of a window equipped with a sash assemblyconstructed in accordance with the present invention.

A flange 13-at the upper edge" of this sash y is fastened by screws 14 to a transverse strip 15 carriedby the window frame. The side edges of sash 12 are held in placeby metal strips 16 provided with sash retaining flanges .17. The metal strips 16 are spaced from the window jamlos 18 by flanges 19 and spacing sleeves 20. Anchoring screws 20a are passed through'thestrips 16 and through the sleeves 20 into the jambs 18. V p

The side edges of the lower sash 21 are arranged to slide insuitablechannel guides attached to the jambs 18 and extending the full height of the window frame. Each chan nel guide comprises an upper stationary section 22 anda lower pivotally mounted secnel, shaped base strip, including

side flanges

27 and 27a. This base strip is arranged with its web 26' spaced from the window amb 18 by the

flanges

27 and 27a and is also provided with a further flange 28 which is preferably formed as an integral continuation of the flange 27 and disposed to project beyond the web in the opposite direction. At its lower end, the web 24 of the channel guide section 22a is secured by a pivot 29 to the web 26 of the base strip, whereby section 22a is mounted to swing into and out of alignment with the upper stationary section 22. When

sections

22 and 22a are aligned, as shown by full lines in Figure 3, the flange 28 of the base strip serves as a weatherprooflng element to preventtheentrance of air or moisture between the web 26 of the base strip and the flanges 30 formed as reverse continuations of the sash engaging flange 23a and arranged to overlap the flange 27a of the base strip. The web 26 of each base strip and the engagingv web 24 of the pivotally mounted guide section 22a are provided with normally registering openings 32 for receiving the bolt or detent (not shown) carried by one of the sash locks indicated at 33 in Figurel. When the

complementary sections

22 and 22a of each guide are aligned as shown in Figure 3, they form a continuous guide channel for the sash 21 extending from the bottom to the top of window frame 11. When sash 21 is positioned between the complementary sec tions 22a of the opposed guides and it is desired to remove the sash this is easily accomplished by swinging said sections 22a about their pivots 29 to the position shown in Figure 2. In this position of guide sections 22a, the sash 21 may be readily removed by drawing the sash upwardly and outwardly along the channels provided between the sash

engaging flanges

23 and 23a.

The

complementary sections

22 and 22a of each guide are formed with inclined meeting edges 34' and 35 adapted for abutting engagement to limit swinging movement of section 22a in the direction of section 22. Swinging movement of section 22a in the opposite direction is limited by a member 36 carried by section 22a and operating in

slots

37 and 38 formed, respectively, in the

side flanges

27 and 27a of the base strip. Member 26 carries a stop lug 39 adapted to engage a portion of the flange 27a surrounding the open- 'ing 28. The slot 37 is made larger than the slot 38 to permit free passage of the member 36v and stop lug 39 when the section22a is swung toan aligned position with reference 'to the section 22.

Web 24, r e e the Web 2.6 of the base t p when the guide sections 22 and 224; are

backed ofl' to remove the head-thereof from;

engagement with the notches 42a, the section 22a is free to swing outwardly with reference to section 22. The arrangement is such that the shank of screw 42 does not interfere with the movement of section 22a when the head of the screw is disengaged from the notches.

As shown by way of suggestion in Figure 9, each side rail of the sliding sash 21 may be provided with one or more springs 43 adapted to engage the flanges 23a; of the

guide sections

22 and 22a. These springs prevent rattling of the sash in the guides and also serve to press the upper rail of the sash 21 tightly against the lower or meeting rail of the sash 12. In order to permit the meeting rails of the

sashes

12 and 21 to be thus maintained in tight engagement with one another, the sash 12 is formed as shown to advantage in Figure 3. In this figure, it will be noted that the frame of sash 12 is made wider than the metal strip 16 engaging the side stiles of said frame. The marginal portions of the side stiles which project inwardly beyond the strips 16 are recessed as indicatedat 47 to receive the flanges 28 of the base strip and the flanges 23 of the

channel guide sections

22 and 22a. This recessing of the sash 12 and the disposal of the flanges 28 andv 23 in said recesses permits the bottom railof sash 12 to be disposed with its inner surface flush with the innersurface of the flange 23 so as to be engaged by the top rail of the lower sash 21. The engaging rails of the two sashes are. maintained in such tight engagement by the springs 43 that weatherprooflng contact is obtained without the use of weathend of the bolt 48 is bent to provide a handle portion 50 projecting outwardlyjthrough a slot 51. The other end of the bolt is'adapted' to co-operate with a notch 52 formed inthe stop member 36 carried by section 22a. When it is found desirable to provide means for holding the guide sections 22a in the outwardly swung position shown in Figure'2,

this may be conveniently accomplished bythe provision of spring fingers 54 carried by the base strip and bearing against the stop member 36, as shown to advantage in Figure 10. r

In Figures and 11 the

weatherproofing flanges

28 and 30 have not been shown as these flanges while important from aweatherproofing standpoint, may be omitted if so desired.

From the foregoing it will be manifest that my invention provides an all-metal sash mounting composed mainly of parts capable of belng produced by simple shaping opguide with reference to any type of window 'frame.
