10 Claims.

This invention relates to window channels such as are used for mounting a glass or sash in a vehicle, such, for example, as an automobile, aeroplane, motorboat, or the like. Under certain con-'- ditions, it is desirable to provide what may be termed a deep channel having more depth than the ordinary conventional Window channel, so that the glass or sash may have a substantial movement transversely of the channel Without actually leaving or pulling out of the channel. It is to such deep window channels that the present invention particularly relates, although many of the features of the invention are applicable also to other forms of channel.

One object of the invention is the provision of a generally improved and more satisfactory deep window channel.

' Another object is the provision of improved means for holding one or more cushioning elements in posit-ion on the Window channel.

Still another object is the provision of a deep Window channel having a sheet metal body which is relatively small in comparison to the depth of the complete channel.

' A further object is the provision, in a Window channel, of improved means for holding a cushioning element, and particularly of such means in connection with an element which is substantially in the plane of a side wall of the channel and extends outwardly to form a continuation of the side wall.

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 side elevation of a window channel constructed in accordance with one embodiment of the invention;

Fig. 2 is a transverse section taken substantially on the line 2-2 of Fig. l;

Fig. 3 is a longitudinal section substantially on the line 3-3 of Fig. 1;

Fig. 4 is a diagrammatic view on a larger scale showing part of the structure illustrated in Fig. 2;

Fig. 5 is a side elevation of a channel cons structed in accordance with another embodiment of the invention;

Fig. 6 is a view similar to Fig. 5 with one Wall of the channel broken away to show the interior construction;

Fig. 7 is a transverse section substantially on the line of Figs. 5 and 6, and

Fig. 8 is a view similar to a fragment of Fig. '7, on a larger scale, to illustrate details.

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

Referring now to the embodiment of the in- 5 vention illustrated in Figs. 1 to 4 inclusive, there is shown what might be termed a deep channel member having side walls |0 and aback and bottom wall l, all formed preferably from a single piece of suitable material, such as sheet metal. 10 This channel-shaped 'member may be wider and deeper than the usual window channel, so that a channel I2 of th-e usual size may be embraced within the deep channel member and secured thereto by any suitable means such as the rivets 3. `'I'his channel member `|2 may be of any suitable known construction, such for example as that shown in Schlegel Patent No. 1,847,700, issued March 1, 1932, orthat shown in Schlegel Patent No. 1,895,688, issued January 31, 1933, or 20 that shown in Schlegel Patent No. 1,928,574, issued September 26, 1933, to mention only a few o-f the kpossible constructions already known to those skilled in the art. In this inner channel I2 may be any suitable cushioning means indi- 25 cated diagrammatically at I5, such for example, as the cushioning means shown in any of the above mentioned prior patents. Cushioning means in the form of relatively long stil' pile such as disclosed in the above mentioned Patent 30 No. 1,847,700, is frequently preferred and is here shown diagrammatically in the drawing.

The two side walls I0 of the deep channel body preferably do not extend through the entire depth desired in the channel, but are terminated 35 somewhat short of the intended extreme outer edge of the channel and are provided with slits or slots 20 extending inwardly from the outer edge to subdivide a portion of the outer edge into a plurality of tongues 2| and 22. Alternat- 40 ing tongues, such as those designated by the numeral 2|, may be displaced laterally 'in one direction, with the intermediate tongues 22 displaced laterally in the opposite direction. 'Ihen a cushioning element is placed between' the 45 tongues 2| and 22 and held in place thereby.

The cushioning element comprises a woven body 25 which may be of flexible or semi-flexible material such as felt or a woven textile fabric of any suitable kind. Preferably it is a textile body 50 woven from weft strands 26 and warp strands 21 indicated diagramamtically in Fig. 4. Some or all of the weft strands 26 are preferably formed of metallic wire to stiften the body, while some or all of the warp strands 21 may be woven 55 of any suitable non-metallic textile material, such as cotton or linen.

The body 25, as shown, lies substantially in the plane of its associated side wall l0 of the metallic channel, and forms, in effect, an outward continuation or prolongation of the side wall. The inner edge of the cushioning element may have a binding strip 30 of suitable sheet material, such as sheet metal, wrapped around the edge as shown, and this bound edge is then clamped between the tongues 2| and 22, which are forced toward a common plane so as to clamp the edge of the cushioning element firmly between them, as is plainly apparent from Fig. 3 of the drawing.

The cushioning element body 25 may itself form 'the desired cushioning pads, or separate cushioning pads may be formed on one or both side walls of the body 25. Such cushioning pads may be in the form of the relatively long stiff pile disclosed in the above mentioned Schlegel Patent No. 1,847,700, or in the form of the cushioning pads disclosed in any of the other above mentioned Schlegel patents, or of relatively long uncut loops as disclosed in the copending application of Charles P. Schlegel, Serial No. 595,- 352, led February 26, 1932, for Window channels, or in any other form known to those skilled in the art. Preferably, however, relatively long stiff pile is used to form the cushioning pads, and this pile may be formed substantially as disclosed in the copending application of Charles P. Schlegel, Serial No. 660,402, iiled March 11, 1933, for Window channel. In this last mentioned application, long stilipile is applied to a woven base, woven in part from metallic wires, and this construction is especially suitable in the present instance The weft strands 26 shown in Fig. 4 of the present drawing may correspond, for example, to the strands 23 shown in Fig. 3 of the drawing of the last mentioned Schlegel application, these strands preferably being mostly or wholly of metal, while the non-metallic warp strands 21 of the present application may correspond to the non-metallic strands 2| the last mentioned Schlegel application. The cushioning pad may be formed, as in the Schlegel application, by relatively long sti' pile strands 3| (corresponding to the pile 30 or 3| of the Schlegel application) woven into the body or foundation strands as disclosed, for example, in said Schlegel application, and held, for example, by weft strands 32 corresponding to the strands 22 of the Schlegel application. These cushioning strands 3| may be formed on one or both sides of the body 25. If only on one side, then they preferably extend inwardly from the inner side of the body 25 toward the mid plane of the channel, to provide adequate cushioning support for a window glass indicated at 34.

One or both of the outer edges of the cushioning elements 25 may be provided with a bead 3'1 formed of any suitable sheet material, such as sheet metal, bent to a rounded cross section and embracing a portion of the outer edge of the cushioning element body 25 and running longitudinally along this edge, as shown. The edge of the cushioning element may be somewhat enlarged, if desired, in order that the bead 3`| may grip it more firmly, such enlargement being secured, for example, by the use of an enlarged warp strand 36 extending along the body 25 approximately at its edge. These beads 31 not only assist in holding the edges of the somewhat iiexible cushioning elements straight and true, but also provided a decorative finish for the outer edges of the channel when these edges are used in a position in which they are exposed to view.

The channel |2 with its cushioning means |5 provides cushioning support for the edge of the window 34 when the window is moved toward the back or base of the channel, which may be to the fully closed position of the window, and which is shown in dotted lines in Fig. 2. The cushioning pads 3| also cushion the sides of the window when it is in this position, and furthermore provide cushioning support for the window when it is moved slightly outwardly with respect to the channel, from the dotted line position to the full line position shown in Fig. 2 of the drawing. Such a movement may be made to open part of the window for Ventilating purposes or the like, as understood by those skilled in the art.

In Figs. 5 to 8, inclusive, of the drawing there is shown a modied embodiment of the invention which is preferred under some conditions. Here, the various elements of the construction may be identical with those of the construction shown in Figs. l to 4 except as hereafter noted, and corresponding elements are designated in Fig. 5 to 8 by the same reference numerals used in Figs. 1 to 4, with the addition of the letter a, Thus the cushioning element in Figs. '7 and 8 is designted 25a, while that in Fig. 2 is designated as 5.

The principal difference between the construction now being described and the previous construction, is tha-t the slits which form the tongues 2|.w and 22a., instead of being substantially parallel to each other to make substantially rectangular tongues, are at an angle to each other to make tongues which are not rectangular. The tongues 2| a are preferably approximately triangular, as shown, with relatively sharp points at their outer ends, and these points are turned over as indicated at 23 to extend in a direction substantially at right angles to the plane of the associated wall |00., so that when the tongues 2|a and 22a. are pressed toward each other to clamp the cushioning element between them, the sharp points 23 (lying preferably just beyond the edgev of the binding strip 30a) press firmly intov and partly through the cushioning element 25a and thus lock it securely in place. Also, the extreme outer edges of the other tongues 22a may extend to a point slightly beyond the edge of the binding strip 30a and may be bent down slightly over the edge! of the binding strip, as shown at 24 in Figs. 7 and 8, to assist in holding the cushioning elements securely.

With this construction, because of the secure interlock between the points 23 and the cushioning element, the Various tongues themselves need not be sosolid and rigid as in the preceding embodiment, and consequently the sheet metal or other material from which the channel member |0a is made may be considerably thinner than in the preceding case. By comparing Figs. 2 and 4 of the drawing with Figs. 7 and 8, it will be seen that the sheet metal Illa, in the latter figures is indicated as being materially thinner than sheet metal I0 in the former figures.

As previously stated, the cushioning pads may be formed on one or both sides of the cushioning elements 25, and in Fig. 7 there are shown cushioning pads 40 on the exterior surfaces of the cushioning elements 25a as well as the cushioning pads 3|a. on the interior surfaces. 'Ihese cushioning pads 4D may be formed in any suitable known manner, as disclosed, for example, in the patents and applications above mentioned, but preferably are formed from relatively long stiff pile in the manner above referred tol in connection with the pads 3|.

When the channel is placed in a groove or rabbet of the window frame of the vehicle to which it is applied, the pads 40 on the lexterior of the cushioning element provide cushioning between the channel and side walls of the groove or rabbet, and thus prevent rattling or squeaking which might be caused by direct contact of the channel with the walls. Obviously such exterior cushioning maybe applied to the form of channel shown in Fig. 2 as well as to that shown in Fig. 7.

Elli/bile 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.
