'I'his invention relates to window channels such as are used, for example, as guideways or runways for movable windows of automobiles and other vehicles, or asA supporting and mounting channels for set or immovable windows in aeroplanes and other vehicles.r

An object of the invention is the provision of a generally improved and more satisfactory channel of this kind, which is easy and inexpensive to construct, easy to install, and effective in use.

Another object is the provision of a window channel which can be readily bent to any reasonable curvature in the plane of the glass embraced by the channel, so that it may be fitted easily around the corners of the window opening.

A further object is the provision of a channel having a body suiiiciently stiff to be substantially self-supporting under normal conditions of use, while at the same time it may be flatte'ned transversely substantially into a plane, for ease Voi? packing and transportation.

A still further object is the provision, in such a channel, of a reinforcing and iinishing member which will assist in holding the edges oi the channel in position, which will furnish a decorative finish for one or both of the edges of the channel, and which will not interfere with easy bending of the channel tomake it conform to corners of the window opening.

An additional object is the provision of a simple self-contained window channel ready for direct application to a vehicle body, which requires no iler or deadener between the channel and the vehicle body, and which may be bent readily into any shape desired'.

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.

The channel of the present invention comprises a main body of material suiciently stiflrv to be substantially self-supporting when placed in a window frame under normal conditions of use, but nevertheless sufliciently flexible so that it may be transversely flattened substantially into a plane for convenience oi'V packing and transpcrtation. The channel body is preferably of woven or textile material. It may be a heavy fabric woven from non-metallic bers, or it may and preferably does include .metallic illaments such as wires woven into the fabric to give it added stillness without interfering with the necessary amount of iiexibility.

In the embodiment illustrated in Figs. 1 to 4 inclusive, the channel comprises `a main body woven from warp strands indicated diagram@ matically at 2i and 22 and from weft strands indicated diagrammatically at 23 and 2 4. Any of these strands may be made, as desired, from either metallic or non-metallic material, so that part or all of the warp strands may be metallic and part or all of the weft. strands may be metallic.

Preferably the warp strands 2| are oi heavy cotton or linen and extend substantially straight along the material. Preferably the weft strands 2l and 24 are of metallic filaments such as wires. and part of the strands are placed in one .plane and part of the strands in another plane spaced For example, the weft strands 23 run trans versely or erosswise of the material in a plane Just above the heavy warp strands 2| when viewed as in Fig. 3, and the other weft strands 2l run from and substantially parallel to the rst plane.`

in the same direction in another plane just below the heavy warp strands 2|.A Preferably also the strands 23 and 24 alternate with each other as shown in Fig. 4, so that there will be rst a strand 23 in the plane above the strand 2|, then astrand 24 in the plane below, then another strand 23 in the plane above, and so forth. Obviously the arrangement of the strands may be altered as desired.

The other warp strands 22 are preferably likewise of non-metallic material such as cotton or linen, but may frequently be lighter than the strands 2|, and are intertwined around the warp strands 23 and 24 as best shown in Fig. 4, passing above the upper or outer weft strands 23 and below the lower or innerweft strands 24, so that these strands 22 tend to hold the strands 23 and 24 against the strands 2| and tend to pull the weft strands in the spaced planes substantially into a single plane.

In order to form lines along which the body may be readily bent transversely into channel shape, the weft strands 23 and 24 preferably cross each other at points corresponding to the corners of the channel, as clearly shown in Figs. 2 and 3, and at such points the strands may be held in crossed relation bythe corner warp strands 25, as indicated diagrammatically in the drawings.

The channel body is preferably provided with any suitable` cushioning or lining means for supporting and cushioning the sash or glass embraced by the channel, and for providing a smooth runway for the glass if it is of the sliding or movable variety. This lining means may be Yformed of pile or any other suitable cushioning material, and may be formed as part of the channel body or as a separate piece or pieces secured to the channel body, as desired. Preferably the lining comprises strips of relatively long, stiff pile woven integrally with the channel body,

the strips extending longitudinally along the inner surfaces of the side portions and of the back or bottom portion of the channel.

The pile on the bottom portion of the channel body is indicated diagrammatically at 3|), while v .is engaged around the u'pper or outer weft strands v23 and `placed between them and the warp strands 22, as indicated diagrammatically in Fig-4, for example.

It'will be understood that in all of the figures of the drawings. the weaving is shown diagrammatically and that in the actual article, the

' strands are usually greater in` number and closer art.

together so that the parts are all held rmly in a manner well understood by those skilled in the Itis also to be noted that the various de- 1 tails of weaving herein described, while preferred,

are notfto be taken in ia limiting sense, and are mentioned as examples of lsatisfactory constructions. `The details of the strands, the manner of Weaving, and so forth, may be-varied at will.

Fig. 2 illustrates the channel described above,

ras applied to a window frame 33 having a rabbet or groove therein in which the woven channel is placed and to which it is fastened as by` tacks 35 driven at intervals through the back or bottom of the channel. ported by the channel is indicated at 34, and may be either fixed or movable along the channel, as desired. As above stated, the woven channel of the present invention, while sufficiently flexible to be bent up into channel form or flattened transversely substantially into a plane, is nevertheless sufficiently stiff to be substantially selfsupporting in use. By this is meant that when the channel is bent into channel shape and placed in the groove of the frame 33 and attached to theframe as above indicated, it will maintain its shape and the side walls will stayin proper position in an effective manner Without collapsing inwardly and without the necessity of fastening the side Walls themselves directly to the frame 33. Thus it is not necessary to employ a sheet metal channel encasing and holding the woven channel, as is done according to some prior constructions. It is noted also that due to the woven construction, tacks or other fastening means may be driven through the channel member at any desired point, and it is not necessary to provide preformed apertures for the fastening means to pass through. i lPreferably the channel construction includes means running longitudinally along one or both edges of the channel to reinforce ythe edges and to provide a more decorative nish or appearance for the edges. To this end, the channel is provided with enlargements running longitudinally along one or both edges, which may be formed by warp strands 3B at the edges of the channel member which are enlarged, that is, formed of cords or Wires of somewhat larger size or diameter than the other warp strands such as 2|. These strands 36 are preferably woven right into the material and surrounded atleast to a substantial extent by the weft strands. The strands 36 may themselves form reinforcing members (especially if made of wire or the like), or preferably one or both of these enlarged edgesare embraced by the reinforcing and finishing member 31 in the form of a hollow member or bead of sheet material open at one side, as plainly shown in the drawings. This member 31 may be formed of any suitable material, such as metal, celluloid, composition, or the like. In practice, it is found that a thin sheet of metal'is satisfactory for forming the bead. l

It is to be noted that the bead 31 is sufficiently The glass or sash supstrong so that it assists in holding the edge of I the channel true and straight, but at the sameW on the channel body so that the bead may slide longitudinally along the body when the body is bent in a curve in the plane of the glass, as illus-` trated in Fig. l. Such longitudinal sliding occurs during the bending operation, to compensate for the difference in length between they bead Iand the outer edge or back of the channel when thus bent. V i.

When some or all of the weft Vstrands ofthe channel are of wire,.as above described, thefweave of the channel body is preferably suiciently loose so that this bending in the plane of the glass` may take place readily. That is to say, the weft strands are preferably spaced slightly from each other, so that the weft strands in the side portions of the bent section of the channel may move closer to each other and converge toward the center of curvature, with the result that these side portions bend smoothly and substantially without puckering.

As above set forth, the reinforcing and finishing bead 31 may be applied to one or both of the edges of the channel, being shown on both edges in Fig. 2 of the drawings. When such a bead is used, the edge of the channel may project slightly beyond the edge of the window oasing or frame 33, as shown in Fig. 2, so that the bead 31 may be visible and will lend its decorative effect to the trim of the vehicle. It will be apparent that the beads 31 may be made in various forms, styles, colors and finishes, as desired.

When a lessA expensive channel construction is desired, or whenever preferred for other reasons, the beads 31 may be entirely omitted, such a ccnstruction being illustrated in Fig. 7. When no finishing bead is employed, the edge of the window frame 33 preferably projects slightly beyond the edge of the channel member so that the channel member is largely hidden in the groove or rabbet of the Window frame, although it may project into view if preferred.

The pile 3| at the sides of the channel is preferably sufiiciently long and stiff so that it holds the sash or glass 34 spaced from the beads 31, or from the enlargements at the edges of the channel if no beads are used. Thus, if the glass is movable, it slides smoothly on the pile alone, and remains out of contact with the beads or enlargements.

A slight variation of the construction above described is illustrated in Figs. 5 and 6 of the drawings, in which a portion of the bottom or back of the channel member is cut away or apertured as indicated at 40, where the channel is curved or bent around the corner. This aperture permits the edge of the window pane or sash 4I to project out through the aperture as indicated at 42. Thus, for example, the window opening in the side of the vehicle may have rounded corners and the channel body may be conformed to this rounded configuration as illustrated in Fig. 5, while at the same ti'me the glass or sash itself may have square or substantially square corners which thus project through the aperture Ill without interference.

In Fig. 8 of the `drawings there is shown a slightly different embodiment of the invention in which the weft strands of wires or metallic iliaments do not extend entirely across the transverse dimension of the channel, but only through part of the width of the channel. For example, in this construction, the weft strands may be lof metallic filaments or wires, and may extend inwardly from the enlarged warp strands 5I to certain other warp strands 52. Other weft strands 53, of cotton or linen or other suitable non-metallic material, may furnish the weft in the central part of the channel, between the two warp strands 52. 'I'he other warp strands 5l and may be substantially the same as the warp strands 2| and 22, respectively, previously described, and the piles 56 and 51 may be placed and held in the same manner above described in connection with the piles 30 and 3|. rWhen the channel is formed or bent up from the flat form illustrated in Fig. 8 to the channel shaped cross section for use, the bends at the corners of the channel may come substantially at the warp strands 52 or at any other desired points.

With this construction, it is seen that metallic strands 50 are used in the side portions or wings of the channel, to stiien these side portions and cause them to hold their shape properly in use, but that the bottom or back portion of the channel may have few wires or none at all woven in it, thus reducing the amount of wire in the channel while still maintaining the side portions with satisfactory stiffness.

In this embodiment cf the invention, as in the embodiments previously described, reinforcing and finishing beads 58 may be employed on one or both edges if desired.

Still another embodiment of the invention isI illustrated in Figs. 9 to 11 inclusive of the drawings, to which reference is now made. Here the main body of the channel is woven entirely or substantially entirely from non-metallic textile material such as cotton, linen, or the like, and contains little or no metallic strands or fibres. The warp strands are indicated diagrammatically at 6|, and the weft strands at 62, the pile for supporting and cushioning the window sash being held in any suitable manner and indicated diagrammatically at 63. vWealrened lines may be formed longitudinally of the channel member at points corresponding to the corners of the channel for easy bending, which weakened lines, for example, may be formed by spacing the warp strands slightly farther away from each other along the corners and by using fone or more slightlysmaller warp strands 64 at the corners.

As before, the warp strands 65 at the edges of the channel may be enlarged, and the enlarged edges of the channel may be embraced by beads 66 similar to the beads 31 previously described, if desired.

As shown in Fig. 10, such a channel may be placed in a rabbet or groove in a window frame 68, and held therein in any suitable manner, such as by tacks or nails 69 driven at intervals through the base or back of the body portion, and the pile 63 serves to support and cushion a window sash or pane 10 which may be either fixed or movable as desired.

This form of channel, like the previous forms, may be readily bent through a curve in the plane of the glass, as illustrated infFlg. 9. 'I'he beads 66, if used, slide longitudinally to a slight extent along the edge of the channel during the bending operation, so as to compensate for the difference in length between the inner and outer edges of the bent portion of the channel, and the side walls of the channel may 'pucker somewhat as indicated at 1|, to accommodate themselves to the curved shape.

When such a channel is made of relatively heavy and tightly woven textile material mainly or entirely of non-metallic strands, it is found in actual practice to be sufdciently stiff so that it is satisfactory and self-supporting inuse, but nevertheless suillciently exible so that it may be readily flattened out transversely substantially into a plane, as shown in Fig. 1l, for convenienceof packing and shipping. Even when no reinforcing wires or metallic filaments are used, the sides of such a channel of relatively tightly woven non-metallic textile material, will remain in place and hold their proper shape satisfactorily under normal conditions of use, as described above in connection with the other embodiments of the forced by the beads 66.

holding means for maintaining the sides of the woven channel in place. The stiffness of the sides of the channels of the present invention is suicientso that sliding movements of the glass or sash will not displace the sides ofthe channels or cause them to buckle or bulge. At the same time, the channels may be easily bent, as by hand for example, to any desired shape, so that they may be readily and quickly applied to window openings of any shape or size, and need not be specially shaped or formed at the factory for each different size or shape of window openmg.

Furthermore, it is pointed out that the window channels of the present invention require no deadening material or filler between the channel and the vehicle frame. The woven channel body itself acts as a suilicient deadener even when placed in contact with metal frame parts. In the preferred form of construction, the nonmetallic warp strands 22 are principally in contact with the vehicle frame and keep the metallic strands 23 and 2l largely out of contact with the frame, so that there is little or no metal-tometal contact between the window channel and any metallic frame parts. 'I'hus there is pro- -vided, in the preferred form, an extremely simple, self-contained, ready-to-apply channel which is highly satisfactory in use, and which .is light and small. l

It is to be imderstood that the terms "fabric" and textile fabric and "textile material" and woven material" as used in this specification and inthe accompanying claims, are not intended to be limited to fabric or material woven fromnon-metallic strands, but are intended to to be interpreted broadly to include material in whichsome or all of the strands are of wire or metallic filaments, as well as material in which some or all of the strands are of animal or vegetable fibers.

While certain embodiments of the 'invention have been disclosed, itis 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 ininvention or the scope of' the appended claims.
