' 3 Claims. I (01. ass-44.5

My present invention relates to window frames and the mounting of sashes therein and more particularly to such window frames as are used in automobiles where a usually unframed plate glass constitutes the window and slides in guides in the frame, and the invention has for its object to provide a simple and eflicient textile lining for the window guide which will reduce friction and render it quiet in its movements but which will be capable of being manufactured at a low cost. The improvements are directed in part toward increasing the wearing qualities of the lining and promoting the ease with which it may be applied to the guide. To ,these and other ends, the invention resides in certain improvements and combinations of parts,.'all as will be hereinafter more fully described, the novelfeatures being pointed out in the claims at the end of this specification.

In the drawings:

, Fig. 1 is a perspective view of a fragment of a fabricated guide lining in the fiat state made in accordance with and illustrating one embodiment of my invention;

Fig. 2 is a transverse section therethrough;

Fig. 3 is a fragmentary enlargement of the section of Fig. 2 to illustrate the weave;

Fig. 4 is a section on the line di of Fig. 3;

Fig. 5 is a transverse section through a fragment of a window and window frame having my Fig.1 illustrative of the manner in which the lining strip is assembled;

Fig. 7 is another similar view of the assembly illustrating a further step, and s Fig. 8 is a side elevation of a section of lining conformed to the curvature of a window frame.

Similar reference numerals throughout the several views indicate the same parts.

Referring first to Fig. 5, I indicates the window frame, 2 the guiding groove therein and 3 the sash or window glass running slidably in the guide. The problem is to line this guide with a soft and friction-reducing and sound-absorbing material, preferably assembled or fabricated as a unit exteriorly and then slipped into the guide and fastened'in some way. In the practice of my invention, I provide a strip of textile material comprising a relatively coarse body fabric 4, what we will call the back or reverse side of which is shown uppermost in Fig. 6. On its face or under side in that figure, it is provided near its lateral edges with two longitudinally extending mats or cushions 5 which project from the surface and the nature of which will be later'described, such cushions being illustrated in Figs. 1, 6 and? in a conventional manner. In the assembly and as 5 shown in Fig. 6, there is laid centrally and longitudinally of the body fabric a metal stiffening strip 6 and on top of that a zig-zag or transversely looped pliable stiffening wire I with straight wires 8 at each side thereof. The free y edges carrying the cushions 5 are then folded over toward the center on the axis of the wire 8 so that they cover the loops of wire i, as shown in Fig.7. The folded and contacting parts are all cemented tightly together with a tenacious in cement in these positions,

The structure is completed by finally applying another strip of fabric 9 to the center of the strip between the folded edges W of the body i and cementing it down securely to constitute a 2 continuation of such portions l0 and completely concealing and embedding the stiffening elements t and i. This strip 9 is also provided with I a cushioning mat ii. p v

My lining is now complete except for forming it to fit the guide channel of the frame, which is done by running it through mill rolls that bend it into the U-shape form shown in Fig. 5. In other words, it is bent angularlyalong the seamsbetween the portions 5 and .9 and toward them and pushed into the channel 2,'as shown in the said figure, so that the portions to become the side walls and the portion 9 the bottom wall with suitable securing devices If extending through the latter, including the stiffening plate ii. The wire '5 supports these side walls as well as the bottom wall and holds-the lining. snugly in place. It is further pointed out that the back or outside of the formed: lining is unbrokenly smooth and continuous without seams or doubled a0 portions so that it fits the guide 2 accurately and slips easily into place therein. The window glass or sash 3 is held between the cushions 5 which support its oppositesides for smooth running while its edges engage the cushion l I at the bottom of the guide. The wires 8 reenforce the slightly projecting edges of the lining, the bend of the fabric about them being further reenforced and being given a finish by split metal tubes l3 that encase them.

With all of the pliable strengthening and stiffening devices described, the formed fabric lining may be easily bent to conform to the rounded corners of a window frame, as-shown in Fig. 8, though it is desirable to notch the tubular finish- 5'5 indicated at H, to facilitate. menu14cm larger radius. 1 I demons [and]! may be of the {'Stlfflcture, in someinstances,
