This invention relates to window guide channels and more particularly of the type as used in automobile bodies where the edge oflthe glass pane is guided in suitable chan- 5 ne s.

An object of the present invention is to provide a channel guide of this character I y that is inexpensive in construction and will grip the edges of the glass panel with sufiicient spring tension to keep the same from rattling while still permitting vertical movement to be imparted thereto.

Another object of the present-invention is to provide a guide channel consisting of a resilient, one-piece sheet metal body portion i having throughout its entire length integral tongues extending therefrom either enerally parallel or at an angle toward eac other and suitable glass-engaging cushioning means, such as a rubber strip on one face of the sheet metal portion having the edges thereof bent around -the ends of the tongues of the metal body portion, the two faces of the rubber strip adhering together where they come in contact betweenthe tongues, and a fabric strip cemented to the rubber strip for engaging the sides and the vertical edges of the glass pane. 'f

Another object of the invention is to provide a device of this character in which the sides of the channel not only have sufficient resiliency to engage glass panes'of varying thicknesses to prevent the same from rattling, but also, have suliicient flexibility or yieldability topermit of twisting or bending of the channel, whereby said channel is enabled to meet rather extreme demands, such as use, for example, in a window frame groove which is not in a straight line.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and preferredl forms of construction by vwhich these objects are attained are shown in the accompanying drawing in which- Fig.` 1 is a sectional perspective view of one form of my improved guide channel en gaging a glass pane. i

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

` Fig. 3 is a detail plan view of one end of the sheet metal backing -strip of the channel of Figs. 1 and 2.

Figs. 4 and 5 are detail views similar t'o Fig. 3 showing modified forms of backing. 55 strips.

Referring now tothe drawing wherein like reference characters designate like parts vthroughout the several views, the sheet metal backing strip 1 of the present channel com- 60 prises a solid central portion 2 having tongues 3 extending from both edges of the central portion 2, said tongues being provided or formed by slotting or notching the sides of said strip, as will be readily understood.

As will be noted from Fig. 3 the transversely disposed 4tongues 3 are longitudinally spaced apart-fora rubber-adhering purpose to be later described, as well as for purposes of general flexibility or yieldability ofl the channel. It is to be understood that the metal backin strip may be constructed in a variety of di erent forms some of which are shown in Figs. 4 and 5. In Fig. 4 the 'tongues 3 are made wider at their outer -or free ends 75 than they are at their inner ends where they connect to the-central portion 2. As shown in Fig. 5, the metal baclnng strip may be perforated as indicated at 5 and if desired the outer edges thereof may be split centrall of the apertures 5 as indicated at 6. As st illustrated in Figs. 1 and 2, the sheet metal backing strip is adapted to be bent into generally channel shape, the strip central por-l tion 2 forming-the base of the channel and 85 the tongues3 forming the side flanges thereof, all as will be readily understood. If desired and as shown, the tongues 3 may be bentin toward each other as indicated at 7. The outer or free ends of the tongues 3, which may constitute the outer or free edges of the channel side flanges, are spaced from each other to lform a vertically extending opening 8 for receiving the sides of the sliding glass 9 therebetween. Forcushioning purposes, the metal backing strip is herev shown as provided with a rubber stri 10 secured to the face thereof nearest thee ge of the pane 9. The longitudinal edge portions of said rubber strip are then bent around the ends of 10 ber strip 10 is cemented to the inner face of the rubber strip, that is, the face or surface nearest the pane of glass 9. The edge of the glass pane 9 will slide against the fabric strip 12 at a point in line with the center line of the central portion2 of the backing strip 1, while the fabric material that is bent around the ends of the tongues-3 willv engage the sides of the pane of glass 9 near its outer edges to keep the same from rattling due either to motion of the vehicle or the kpressure of the wind exerted thereon. It will be understood that the metal backing strip 1 and the fabric strip 12 and the rubber strip 10 may all be united together to form one strip and then said resulting strip bent into generally channel shape or the backing strip 1 may be first formed in the generally channel shapev as indicated in Fig. 1, and then the fabric and rubber applied lto it. It will be understood also that other forms of cushioning means may be provided, the form here shown in Figs. 1 and 2 and herein described being illustrative merely of one embodiment of the present invention. It will thus be seen that I have provided a guide channel of inexpensive construction and Which may be quickly and easily assembled and that the guide channel will allow free sliding movement of the pane of glass while still keeping the same from vibration.

1t will also be. seen that inasmuch as the rubber and fabric strips are compressible to a certain extent, different variations in the widtli of the glass inserted in the guide channel will be compensated for and also the resilient metal tongues 3 being of sufficient fiexibility will permit the insertion of different thicknesses of glass in the guide channel, and Will also permit twisting and bending of the channel, all as will be readily understood.

Having thus fully described my invention, its utility and mode of' operation, what claim and desire to secure by Letters Patent of the United States is- 1. A guide channel, including a generally l ends of the tongues of both of said side flanges, and a fabric strip secured to said rubber strip and having itslongitudinal edge portions overlying the longitudinal edge portions of said rubber strip.
