Application July 15, 1935 Serial NO. 31374 8 Claims.

This invention appertains to windows of the type'shownin the applications for patents of Jesse R. Howard, Serial Nos. 654,214 and 7,399; filed, respectively, January 30, 1933, and February 20, 1935, and is an improvement thereover.

One of the primary objects of the present invention is toprovide sliding and swinging sashes for window frames of such a character that the same can be associated with window frames of substantially standard or ordinary structure with the use of a amount of time and labor.

Another object of the invention is the provision of novel guide rails or tracks for receiving the slide plates or supports for the sashes, whereby free sliding movement of the sashes is permitted, and whereby a durable and leak-proof window will be had, the guide rails being of an integral structure, and so constructed as to be fastened to the frame as a single unit on each side thereof for receiving both the upper and lower sashes.

Another prime object of the invention is the provision of novel means for associating the sashes with the slide plates so that the sashes will have free swinging movement thereon, and whereby the sashes can be quickly connected with or entirely disconnected from the slides to permit the bodily removal of the sashes when necessary or desired.

A further object of my invention is to provide novel means for automatically locking the slide plates against sliding movement when the sashes are swung to their open or partly open position, the sashes automatically releasing the slide plates when the sashes are in their closed ,position, to permit raising and lowering of the sashes with the slide plates.

A further salient object of my invention is the provision of novel means carried by the slide plates for engaging the guide rails, so that the seeping of air and moisture between the slide plates and rails will be eliminated, novel means being also provided for forming a leak-proof connection between the sashes themselves and the guide rails.

.A still further object of my invention is to provide an improved window of the above charaoter', which will be durable and efiicient in use, one that will be simple and easy to manufacture, and one which can be placed uponthe market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described,- claimed,

and illustrated in the accompanying drawings, in which drawings:

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views,- the letter W generally indicates my improved win- "dow, which comprises a frame l5, and upper and lower sashes l6 and IT. The window frame I is of substantially conventional construction, and. includes the side stiles I8 and [9, the lintel 20, and the sill 2|; The sashes I6 and I! are also of substantially ordinary construction, and thesash l6 includes the side rails 22, the top rail 23,- and of the wear plates.

the bottom or mid-rail 24. The lower sash |1 includes the side rails 25, the bottom rail 26, and the top or mid-rail 21.

In accordance with my invention I provide novel guide tracks 28. These guide tracks are formed from the desired type of metal, and are either cast or extruded, as may be preferred. These rails are rigidly secured to the side stiles l8 and I9 of the window frame in any desired way, and extend from the sill 2| to the lintel 20. By

providing these rails I eliminate the usual stop and parting beads, but finishing strips can be utilized, as shown in Figure 3 of the drawings. Each guide rail includes spaced, parallel longitudinally extending channel portions 29 and 30 for receiving the slide plates 3| and 32 for the upper and lower sashes l6 and H. The channels 29 and 30 are connected by an integral bridge or Web piece 33, and the edges of the bridge piece are extended to provide longitudinally extending guide and stop flanges 34 and 35. The front channel 30 for the bottom sash has its opposite sides provided with inwardly directed, longitudinally extending ribs 36 and 31.

The channel 29 has the inner surface of its rear side wall provided with an integral rib 38, which extends in longitudinal alinement with the flange 34. Extending inwardly from the rear side wall of the channel 29 is a longitudinally extending angle-shaped flange 39, and it is to be noted that this flange extends beyond the web 33 and the front rib 3! of the channel 30.

The slide plates 3| and 32 for the upper and lower sashes are of a particular construction, and are shaped to conform to the configuration of the channels so as to have free sliding movement therein. The outer corners of the slide plates are rabbeted, as at 40, to receive the ribs and flanges 36, 31, 38, and 34. The upper ends of all of the slide plates are shaped to detachably receive the lower ends of the sash cords 4|, and these sash cords are provided with counter-balancing weights or springs in the ordinary way. The lower ends of all of the slide plates are provided with pivot or bearing openings 42, for a purpose which will be later set forth.

In order to prevent the seeping of air and moisture up the channels 29 and 30 past the slide plates, each of the slide plates adjacent to their opposite ends carry felt pads 43, which frictionally engage the side and rear walls of the channels. The side edges of the upper and lower sashes have rigidly secured thereto longitudinally extending metal wear plates 44. These metal wear plates have their inner edges folded back and then bent to provide guide channels 45, which are disposed in rabbets formed in the inner corners of the sashes.

By referring to Figure 3, it can be seen that when the sashes are in their vertical positions, the ribs 35 and 39 are received within the channels 44, which tend to create a leak-proof construction. In order to further give an air-tight and leak-proof window, longitudinally extending felt strips 46 are placed within the channels 44, and are secured thereby by angle iron strips 41. The angle iron strips are riveted or otherwise secured to the channels 45, and serve to hold the felt strips 46 in intimate contact with the side walls of the channels 29 and 30.

The lower side edges of the sashes Hi and I! are cut away to provide pockets 41 inwardly of the wear plates 44, and these pockets receive leaf springs 48, which normally abut the inner faces The leaf springs 48 are secured to the wear plates adjacent to their upper ends, and their lower ends carry outwardly extending pivot pins or pintles 49, which are adapted to extend through openings 50 in the wear plates. Thumb-buttons 5| are formed on the leaf springs 48 intermediate their ends, and these buttons are accessible through openings 52 formed in the wear plates so that the springs can be depressed to move the pivot pins 49 inwardly.

The slide plates 3| and 32 are associated with the channels 29 and 30 prior to the placing of the guide tracks in the frame. After the guide tracks are in place the sashes are connected with their slide plates by moving the pivot pins 49 inwardly and placing the sashes in the frame at an angle until the pins register with the bearing openings 42 in the slide plates, at which time the leaf springs 48 can be released.

,Pivot pins 49 engaging the walls of the bearing openings 42 will allow free swinging movement of the sashes, and hence sashes can be swung to a vertical closed position, or to an open angle position, as may be desired. The upper sash I5 is of a slightly less width than the lower sash I1, and

consequently the upper sash can freely swing past the web 33; The wear plates for the sashes have formed thereon, or secured thereto, stop pins 53 above the, pivot pins 49, and when the sashes are swung to an open position the pins are adapted to ride through grooves or slots 54 and 55 formed in the guide tracks 28. The slots or grooves 54 are formed in the web 33 so that the stop pin carried by the upper sash can swing therethrough. The slots 55 are formed in the ribs 31 so that the stop pins carried by the lower sash can swing therethrough. The sides of the window frame are provided with grooves 56, and these grooves may be continuations of the slots 55 formed in the guide tracks 28. This allows the stop pins to swing freely past the window frame, and by this arrangement the window sashes can be readily swung bodily into a room, to permit the cleaning of the opposite faces of the windowpanes. This position is clearly shown in Figure 6 of the drawings.

To hold .the lower sash in a partly swung open angular position for ventilating purposes, the guide tracks 28 have their ribs 31slotted, as at 51, below the slots 55. The inner faces of the stiles of the window frame are also grooved for the reception of guides 58, which are adapted to receive the stop pins 53. Obviously the sashes can be swung open by sliding the sashes forwardly until the stop pins register with the desired slots in the guide tracks.

The slide plates 3| and 32 carry spring-pressed latches 59, and these latches are adapted to snap into the slot 55 or 51, as the case may be, to hold the slide plates against sliding movement when the sashes are in their swung open position. When the sashes are in their vertical position, the stop pins 53 are adapted to engage the latches and move thesame inwardly whereby free sliding movement of the plates and sashes is provided. 1

Obviously, the sashes and the window frame can be provided with any .desired type of cooperating means for securing the sashes in a tightly closed position. Likewise, the mid-rails of the sashes and the top rail of the upper sash and the bottom rail of the lower sash can be provided with an approved type of weather strip.

Fr-om the foregoing description it can be seen ,that I have provided anexceptionally simple and desirable type of window embodying sliding and swinging sashes.
