SASI-I GUIDE.

Application filed May 12,

This invention has to do with sash guides of the detachable side wall type developed by me and disclosed in my pending application, Serial N o. 106,841 tiled May 5, 1926.

The primary object ofthe invention is to provide an improved sash guide of the type described, in which the detachable side wall is caused to bear resiliently against the associated sash by a spring which acts against such side wall.

Other objects and advantages will be evident to those skilled in the art upon a :t'ull understanding of the improved sash guide.

Three diit'erent forms of the invention are presented herein by Way of illustration, but it will be appreciated, of course, that the invention may be embodied in other forms coming equally within the comprehensive scope ot' the claims.

In the drawing:

Fig. 1 is a fragmentary side view of a sash associated with the improved guide;

F ig. 2 is a transverse section through the guide, with the sashV removed;

Fig. 3 is a similar section, with the sash in position;

Fig. 4 is a perspective view of the retaining strip willen constitutes the detachable side wall of the guide;

Fig. 5 is a transverse 'section through a double sash guide, showing the invention in a slightly modified form.

ig. 6 is a transverse section through a guide embodying another slightly modified form of the invention;

Fig. 7 is a similar section, sash in position; and

Fig. 8 is a perspective view of the retainin strip shown in Figs. 6 and 7.

he sash guide illustrated in Figs. l to 4 inclusive consists ot a fixed strip 10 and a detachable strip 11. The strip 10 is adapted to be attached to the jamb of a window frame by .screws or other suitable means, and is provided, at one side, with a groove 12, and, at the other side, with a lixed side wall 13. If it is desired to have a guide in which the sash may be removed from either side, the fixed side wall 13 may be dispensed with, and another groove, corresponding to the roove 12, may be provided at that side of te strip in lieu of the fixed side wall. The strip 10 is made of sheet metal, and is bent in such a way as toform the groove 12, the fixed Vside wall.13 and an intervening showing the 1927. Serial No. 190,709.

`vide the portions described. The strip 11 constitutes a removable side Wall opposite the fixed side wall 13, and is seated within the groove 12. The portion of the strip 11 within the groove is provided with a spring strip 15, which is soldered or secured in any suitable fashion to the inner edge ot the strip and extendsa't an angle from the same.

When the strip 11 is vseated in the groove .12 in the strip 10, Without any sash being in association with the guide, it will assume thecanted position shown in Fig. 2, but when a, sash 16 is in place in the guide, with one side wall 17 oi the sash side wall 13 ot' the strip 10, the strip 11, upon being inserted in the groove in the stri will be held out by the side Wall 18 of the sash in a position generally parallel to the lined side wall 13 of the strip 10, as shown in Fig. 3, and will be pressed resiliently against the side wall 18 of the sash by the spring action of the strip 15.

The groove 12 is preferably a little V- shaped in cross section, in order to provide ample space into which the portion of the strip 11 within the groove may move as the projecting portion of the strip opposite the Xed side wall 13 approaches that side wall in moving Iinto engagement with the side Wall 18 of the sash. y

The strip 11 may be held in position in the groove 12 by any suitable means. Preferably it is held in position by providing bayonet slots 19 at intervals in the strip, which slots are adapted to interlock with rivets or screws 20 which extend at corresponding intervals across the groove. After the strip 11 has been shifted into interlo'cked engagement with the members 20, the strip may be held against further movement by means of ascrew 21 which extends across the groove and passes through an aperture 22 in the strip.

The strip 11 may be provided. intermediate its edges, with an offsetting portion 23, which, when the strip is seated in the groove 12. practically covers the open face of the groove.

The sash guide illustrated in Fig. 5 is of double as distinguished from single construction. and is designed to recelve two sashes 24 and hold the same in spaced relation to each other-which is the sash aragainst the fixed lll) rangement generally employed in railway car window construction. The portion of the guide cooperating with each sash is provided with two grooves 25, one at each side of the sash, and such grooves are adapted to receive detachable retaining strips 26 which permit either sash to be removed in either direction. The two outside grooves in the guide are produced by bending the margins 27 of the fixed strip 28, and the two inside grooves are produced by attaching a supplemental strip 29 of U-shaped cross section to the intermediate portion of the strip 28.

The strips 26 are provided with spring strips 30, and the strips 26 are bent upon themselves in such a way as to clamp the strlps 30 securely in position without the necessity of using solder or other securing means. The strips 26 are fulcrumed against the sides of the grooves 25 at 31, and the spring strips 30 press against the side walls of the grooves adjacent the bottoms thereof and tend to press the outer edges of the strips 26 resiliently against the side walls of the sashes. At those points where the strips 26 fulcrum against the side walls of.

the grooves, the side walls may be slightly bowed in order to interlock frictionally with correspondingly bowed portions of the strips 26, thereby dispensing with the necessity of using any additional positioning means for the strips.'

In the sash guide illustrated in Figs. 6 to 8 inclusive, the spring strip 32, instead. of being soldered to the removable strip 33 as shown in Figs. l to 4 inclusive, is clamped against a portion of the same in a locking groove 34 of a reversely bent and correspondingly grooved fiange 35 along the outer edge of the strip. From the groove 34 the strip 32 extends inwardly `to the inner edge of the strip 33, where it is folded back about such edge and projects at an angle to the strip 33 in spring-pressed engagement with the opposing si'de wall of the groove 36 in the ixed strip 37.

In all three forms of the invention described, the improved spring mounting of the detachable side wall or walls of the guide serves to hold the sash resiliently in position in the guide, and serves to afford a Weatherproof closure throughout the length of the same, both along the line of contact of the detachable side wall with the sash and along the line of contact of the spring strip with the side wall of the groove. When a guide embodying the invention is employed as a sash mounting, removal of the sash from the guide for any reason, such as re-glazing or repairing, is an exceedingly simple matter.
