3 Claims.

This invention relates to window channels, such for example as those employed to hold and guide the sliding window of an automobile, and pertains more particularly to the channel lining which cushions the window against vibration, yet permitting it to be easily and quietly moved in the channel member.

One object of the invention is the provision of a lining of the above kind adapted for use with material of an inexpensive character.

Another object is the provision of a lining of this class capable of being manufactured at a low cost.

A further object is the provision of such a lining which is simple in construction, pleasing in appearance and effective in use.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinaftermore fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawing:

Fig. 1 is a sectional view taken transversely of a window channel constructed in accordance with one embodiment of the invention;

Fig. 2 is a sectional view of another embodiment;

Fig. 3 is a sectional view of another form of window channel;

Fig. 4 is a sectional view of still another embodiment, and

Fig. 5 is an enlarged sectional view of the strip which forms one of the cushioning pads for the channel lining illustrated in Figs. 3 and 4.

The same reference numerals throughout the several views indicated the same parts.

The present invention is embodied, in the present instance by way of illustration, in a window runway comprising a channel member of substantially rigid sheet material such, for example,

as sheet metal on the inner faces of which a suitable lining is arranged. This lining is provided with pads of resilient material stitched or otherwise secured to the lining to provide cushioning means for the window channel. This application forms a continuation in part of my copending application Serial No. 567,247, filed October 6, 1931.

Referring now to the drawing, Fig. 1 shows a sheet metal channel member formed to provide a bottom 11 and side walls 12. The free edges of the side walls are rolled or reversely bent to form flanges 13. The channel member is provided with a lining 15 the free edges 16 of which are disposed under and held by the flanges 13. This lining preferably comprises a plain or fancy woven fabric of an inexpensive character, and of a good wearing and friction reducing quality, such for example; as broadcloth, although other 'material suitable for this use will occur to those skilled in this art. This lining is adapted to support a sliding glass sash and to afforda free sliding surface therefor which is not materially affected by moisture or freezing weather conditions.

As the lining or surfacing material 15 is of relatively thin material, it is preferred to provide a pad or strip of resilient material 1'? interposed between the lining 15 and the sides 12 of the channel member, and also between the lining and the bottom 11, if desired. In the present embodiment this pad preferably comprises a single strip of cotton batting, felt, or othersimilar ma terial arranged on the inner faces of the bottom 11 and side walls 12, and held in place therein by the lining 15. The upper edges 18 of the pad preferably terminate below the flanges 13, as clearly illustrated in the drawing, to permit the endportions or free edges 16 of the lining to be inserted under and held by the flanges 13. The pad is preferably secured to the lining by means of rows of stitching 25 and 26, which extend through the portion of the lining arranged on the side and bottom ofthe channel, respectively, as clearly shown in Fig. l. I

In the embodiment shown in Fig. 2 the channel member is of the same construction as that illustrated in Fig. 1, and corresponding parts are designated by the same reference numerals.- The channel is provided with a lining 15a, preferably of the same material as the lining 15, arranged adjacent the inner faces of the channel, and having the free edges 16a thereof inserted under and held in place by the flanges l3. Cushioning pads 17a and 18a are secured to the outer face of the lining 15a, as hereafter described, intermediate the lining and the walls of the channel member to space the sash engaging portions 20a of the lining from the rigid channel member. These pads are preferably made of an inexpensive material such, forexample, as cotton, felt, paper, or other suitable material of like character. The pads 17a and 18a are preferably spaced to provide breaks 21a, intermediate the pads, which enable the lining to be bent into channel form. The pads 1811 are also preferably terminated short of the edges 16a to permit the latter to be inserted under the flanges 13a. The pads 17a and 18a are preferably secured to the outer face of the lining by any suitable means such, for example, as rows of stitching 25a and 26a, which extend through the lining 15a and the pads 18a and 17a, respectively, to secure the pads to the lining.

In the embodiment illustrated in Fig. 3, the lining 15b is preferably of the same material as the lining 15 and 15a above described, and is arranged adjacent the inner faces of the channel member with the free edges 16b thereof inserted under and held in place by the flanges 13. Resilient woven textile cushioning pads 17b and 18b, hereafter more fully described, are provided on the bottom and sides, respectively, of the channel intermediate the channel member and the lining 151), as clearly illustrated in the drawing. These pads are preferably secured to the lining 15b, as hereafter described, and space the sash engaging portions 20?) thereof inwardly of the rigid channel member. Breaks 21b are provided intermediate the pads to permit the lining to be bent into channel form for insertion in the channel member. The pads 18a are terminated short of the free edges 16?) to facilitate the insertion of the latter under the flanges 13. Rows of stitching 25b and 26b are extended through the lining 15b and the pads 18b and 17b, respectively, to secure the pads to the outer face of the lining.

From the foregoing description it is apparent that each of the above described channel constructions provides a strong rigid channel member, a resilient pad for cushioning the sash and spacing parts of the same from the rigid channel member, and a friction reducing lining overlying and secured to the pads, the lining being in turn securely held in place by the reversely bent flanges formed on the channel member. This lining provides a smooth sliding surface which is not affected by moisture or freezing weather conditions and thus enables the glass to be easily and quietly moved in the channel member, even under severe atmospheric conditions. The use of the resilient cushioning pads gives the desired body and softness to the lining of the rigid channel to prevent rattling of the sash and to cause the lining to project inwardly, as shown, to space the glass sash from the rigid flanges 13. It is evident that such an arrangement of the parts provides a channel construction which not only embodies the desirable advantages of prior constructions, such as rigidity and strength, effective cushioning qualities, and a durable friction reducing surface for contacting with the glass sash; but which may be manufactured at a greatly reduced cost.

Referring now to Fig. 4, there is shown a further modification in which the lining 150, of any suitable material, is arranged on the inner faces of the bottom 11 and side walls 12 of the channel member, and has the free edges 16c thereof disposed under-and held in place by the flanges 13. Woven cushioning pads 17c and 180, of the same construction as the pads 17b and 18b illustrated in Fig. 3 and hereafter described, are secured to the inner face of the lining 15c and extend inwardly therefrom to engage the side edge and the faces, respectively, of a sliding glass sash. The pads 17c and 180 are preferably slightly separated to provide breaks 210 which permit the lining to be bent into channel shape for insertion in the channel member. The pads 18c are preferably terminated short of the free edge 160 to facilitate the insertion of the latter under the flanges 13. The pads are secured to the inner face of the lining 150 by any suitable means such, for example, as rows of stitching 25c and 260 which extend through the lining and the pads 18c and 170, respectively, to secure the pads to the inner face of the lining.

The cushioning pads illustrated in Figs. 3 and 4 are of woven textile material formed to provide cut long pile surfaces, such as disclosed in my copending application now Patent N0. 1,847,700, issued March 1, 1932, or uncut pile surfaces as described in my copending application Serial No. 400,125, filed October 16, 1929, or relatively long loops of a heavy strand material such as disclosed in my copending application Serial 100 No. 595,352 filed February 26, 1932.

While certain embodiments of the invention have been disclosed, it is to be understood that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details described, but is intended to cover all variations and modifications thereof falling within the spirit of the invention or the scope of the appended claims.

I claim:

1. A window channel comprising a supporting channel-shaped member, textile fabric surfacing material arranged in said member for contact with the window glass, and one or more woven pads on said material between the latter and said 115 member to provide cushioning support for the glass.
