4 Claims.

This invention relates to channel members such, for example, as those used to hold and guide the sliding window sash of an automobile, and pertains more particularly to the material for linin the channel members so as to resiliently cushion the sash against vibration and to permit it to slide easily and quietly in the channel members.

One object of the invention is the provision of a new and improved channel lining of the class described which is simple in construction, inexpensive to manufacture; and effective in use.

Another object is the provision of a woven lining of this kind which is adapted for use'with materials of a relatively inexpensive nature.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more 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 transverse sectional view of a channel Fig. 5 is a view similar to Fig. 4, the warp strands of the foundation weave being broken I away for the purpose of clearness;

Fig. 6 is an enlarged fragmentary sectional view taken transversely of the channel lining illustrated in Fig. 3, showing the method of forming thick cushioning pads on opposite faces of the lining strip, and

Fig. 7 is a view similar to Fig. 6, the warp strands of the foundation weave being broken away as in Fig. 5, for the purpose of clearness.

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

Referring now to the drawing, Fig. 1 shows a channel member of substantially rigid sheet material such, for example, as sheet metal formed to'provide a bottom 11 and side walls 12, the free edges of which are reversely bent to form flanges 13 spaced from the side walls 12. A lining, preferably in the form of a strip of textile fabric, is

I arranged on the inner faces of the bottom and side walls of the channel, and is provided with spaced cushioning pads 16 and 17, hereafter dethe lining to be bent into channel form. The

pads 16 are preferably terminated short of the free edges of the strip to provide thin marginal portions 20 whichextend under and are clamped by the flanges 13.

The channel construction illustrated in Fig. 2. comprises a channel member of sheet material similar to that shown in Fig. 1, corresponding parts being designated by the same reference numerals. The channel member is provided with a lining, preferably in the form of a strip of textile material, arranged adjacent the inner faces of the bottom and side walls of the channel. The strip is provided with cushioning pads 16a and 17a, hereafter more fully described, woven on the outer face of the strip to provide cushioning means between the strip and the rigid channel member. In this embodiment, one face of the strip is adapted to engage'the sash while the pads 16:: and 17a provide cushioning means therefor, and space the sash engaging portions thereof inwardly of the rigid channel member. Breaks 190 are provided intermediate the pads to permit the lining to be bent into channel shape. The pads 16a are terminated short of the free edges of the lining to provide marginal portions 200 which extend under and are held by the flanges 13.

Fig. 3 shows still another modification in which the channel member is similar to that illustrated in Figs. 1 and 2, corresponding parts being designated by the same reference numerals. In-this embodiment, the channel lining is of textile material and is provided with pads 16c and woven on one face of the strip, and pads 16d and 17d woven on the other face in the manner hereafter described. The pads 16c and 170 are on the outer face of the strip intermediate the strip and the walls of the channel and space parts of the strip therefrom, and the pads 16d and 17d are on the inner face of the strip and extend inwardly therefrom to engage the sash and to provide a resilient support therefor. The pads are separated by breaks 19b which permit the lining to be bent into channel form for insertion in the channel member. The pads 16c and 16d are terminated short of the free edges of the strip to provide marginal portions 20b which extend under and are held by the flanges 13.

In my prior application Serial No. 233,161, now Patent No. 1,847,700, issued March 1, 1932, I have described and claimed a fabric lining formed to provide pile cushioning surfaces, and in my application Serial No. 400,125 I have described and claimed such a construction provided with an uncut pile surface to resiliently cushion the glass sash. The present invention resides in a further embodiment of the same general character; but provides a less expensive form of construction which facilitates the use of cheaper materials while accomplishing the desired result of resiliently cushioning the sash, yet permitting it to slide easily and quietly in the channel member.

Referring now to Figs. 4 and 5, there is shown an enlarged fragmentary sectional view of the strip from which the channel lining in Fig. 1 is formed. This strip comprises a relatively thin, foundation or ground weave on the surface of which the pads 16 and 17 are woven in the manner to be presently described. The foundation weave comprises a plurality of warp or longitudinal strands 25 and a plurality of weft or cross strands 26 interlocked with the warp strands in the manner well known in the art.

In the present invention, each of the pads 16 and 17 comprises a plurality of substantially parallel warp strands 30 of relatively heavy inexpensive textile material, such as cotton, which are caught at spaced points under weft strands of the foundation weave, as clearly shown at 35, Fig. 5. Intermediate these points the strands 30 extend over two or more, in the present instance three, of the adjacent weft strands 26 to provide long fiat resilient loops 36 which lie substantially on the surface of the foundation weave to provide a thick padding surface adapted to support and cushion a sliding glass sash. The loops of the adjacent strands 30 are staggered, as shown in Figs. 4 and 5, so that each loop cooperates with the loops of the adjacent strands to provide a substantially flat surface in engagement with the sash. Figs. 4 and 5 show only two of the heavy warp strands 30, but this is for the purpose of clearness only as it is understood that the number of such strands may be varied to provide pads of any desired width. The pads 16a and 17a are formed in the same manner, and are substantially the same size as the pads 16 and 17,

above described.

It may sometimes be desirable to provide a channel lining having resilient cushioning pads arranged on both the inner and the outer faces thereof. To this end, the present invention provides a lining, Figs. 6 and '1, comprising a foundation weave similar to that shown in Figs. 4 and 5 and having warp and weft strands 25c and 260 respectively. This foundation weave has pads 16c and 170 woven on the outer face, and pads 16d and 17d woven on the inner face thereof, as shown in Fig. 6. Each of the pads 16d and 17d is formed of heavy warp strands 30d, of the same material as the strands 30. which are caught at spaced points under weft strands 26c of the foundation weave, as shown at 350 Fig. '7. Intermediate these points, the strands 30d extend over two or more, in the present instance three, of the adjacent weft strands 260 to provide long fiat loops 3611 which lie on the inner face of the strip to provide resilient cushioning pads in engagement with the sash. The strands 30d are preferably smaller than the strands 30 for obvious reasons.

While the pads 16d and 17d are arranged to engage the sash, the pads 16c and 17c are disposed intermediate the lining and the walls of the rigid channel to space the sash engaging portions of the lining therefrom. Each of the pads 16c and 170 comprises a plurality of warp strands 300 of textile material preferably, although not necessarily, of smaller diameter than the strands 30d. These smaller strands are caught at spaced intervals under the weft strands 260 of the foundation fabric, as shown in Fig. '7. Intermediate these points, the strands 30c extend over two or more, in the present instance, three, adjacent weft strands to provide long flat loops 36c arranged on the outer face of the lining to provide cushioning pads or between the lining and the walls of the rigid channel member.

It is apparent from the above description, that the present invention provides a channel lining of an inexpensive construction which facilitates the use of materials of a less expensive nature, and which resiliently supports the sash against vibration and permits it to slide easily and quietly in the channel member.

While one embodiment of the invention has 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.
