June 19, 1933,V Serial No. In Canada'April .15, 1933 Application v 4 claims.'

This invention relates to lwindow channels such,

as may be used to support and guide a movable window pane or glass in automobiles, aeroplanes,

or othervvehicles, or as a mounting for an immovable or set window pane or sash in such vehicles.

An object of the invention is to provide a generally improved or more satisfactory window channel of this character, which can be easily and yinexpensively manufactured, and yet which will retain itsshape and be satisfactory in use.

Another objectof the invention is to provide at minimum expense a window channel having a sumciently soft and resilient cushioning action on the window, together with reinforcing means which will hold the channel in proper position and eissiwlich will enable the channel to be bent as e re certain improvements and combinations of channel illustrating it bent around a corner.

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

Referring rst to Figs. 1 and 2, there is shown a body of suitable fabric which is suiiiciently thick and sufllciently resilient in a direction through this thickness so that iti provides a substantial cushioning support relatively long stii pile as disclosed in Schlegel Patent No. 1,847,700, issued March 1, 1932, or by providing it with` other suit-'- f able cushioning means such as shown, for instance in Schlegel Patent No. 1,895,688, issued January 31,/ 1933, or in copending Schlegel applif cation Serial No. 595,352, filed February 26, 1932;

Inthe preferred form the fabric has a textile body I woven from non-metallic threads or strandsl such as cotton or linen, and the cushioning resilience is secured by providing relatively vlong still pile on those portions 'of the body I 0 which constitute the inner surfaces of the, side and bottom walls of the body when itis bent into the channel shape illustrated'in Fig. 1. For example, this rel-A ativelylong stiff pile on one of the side Walls is indicated diagrammatically at Il; that' 'qnt-,he

and weak non-resilient so that tending lengthwise of UNITED STATES PATENT oFFlca assigner to Company, Bochopposite side 'wall is indicated at I2; and that on the bottom wall is indicated at I3.

As may be seen from Figs. 1 and 2, this pile need not cover theventire inner surface of the walls of the channel member, but preferably occurs in longitudinally extending strips of sumcient width to support and cushion adequately the glass or sash, which is indicated diagrammatically in dotted lines at I5. 'I'he pile, being preferably long an'd stiff as distinguished from the relatively short pile ordinarily found in velvet, for example, will hold the window I5 away from the main side and bottom walls of the body I0 of the.

channel member and will provide an adequate resilient cushioning support for the window and body I0 may-be made of' relatively light material which would not of itself be suillciently stiif tobe self-supporting in use. and exible reinforcing means is provided for holding the body suillciently stiiily in proper position while still'allowing it to be attened out transversely substantially into a plane or erected .into channel form and to be bent around corners in the plane oi' the window embraced by the channel. 'Ihis reinforcing means is also substantially A it tends to remain substantially in a position to which it is bent or formed, holding the sides of the channel normally in parallel relation to each other at `all times irrespective of movements of the glass embraced by the channel. It does not tend to press the sides of vthe channel tightly against the glass, nor to move the sides of the channel toward each other to close -up the channel when the glass is removed or withdrawn.

The reinforcing means is preferably in the form of a flexible non-resilientwire arranged in zig? zag fashion on the outer or exterior the side and bottom walls of as indicated at 20 in the drawing.. The wire is looped back and forth, extending diagonally around the channel, as best4 shown in Figs. 3 and 4, and the ends of the loops are arranged close to the free edges of the -side'walls of the channel member and are bent back relatively sharply upon themselves as at 22, so that the wire does not extend in longitudinal direction along the channel for any material distance. It will be noted also that the successive loops or corners 22 ofthe wire are spaced a. substantial distance from each other. 'I'his fact of substantial spacing of successive adjacent loops, together with the fact that the loops are formed with sharp bendswithout exthe channel through any material distance, permits the channel to be bent smoothly and evenly aroundcorners in the plane ,surface of of the window embraced bythe channel, as

Also if successive loops bracing'and secured to said fabric body to hold were closely adjacent each other, they might the side walls of said body in substantially parallel Y come into contact with each other and interfere relationship to each other, said wire reinforcing with proper bending of the channel around cormeans including wire portions extending in a l ners.
