WINDOW GLASS CHANNEL LINING Filed March 14, 1956 ipr M Patented Oct. 27, 1936 UNITED STATES PATENT -OFFlCE 3 Claims.

This invention relates to certain improvements in weather strips or linings for window glass channels of the general type shown in my pending application Serial No. 60,783, filed January 25, 1936, which are employed to cushion and guide the glass at the sides of a deep channel, in which an edge guide for the glass, if employed at all, is separate from the guiding means which engage the sides of the glass.

When weather strips or linings of this type are installed, it is frequently necessary to cut the strip at an oblique angle, and an objection to the type of strip shown in my said application is to the effect that the tongues of the core, when out from the continuous edge portion, are liable to become disconnected from the wire, or bead to which their ends are connected, and because they are unsupported at both ends, are liable to become a source of noise in a moving automobile.

The objects of my invention are to provide a form of weather strip of the type above referred to, in which no metal parts are exposed, or required to provide an ornamental finish, and in which a metal core is provided which is not notched, or slotted, but may nevertheless be bent sufiiciently to conform to the curvature of the window frame in which it is to be installed, without appreciable distortion.

I accomplish these objects by providing a core 'consistingof narrow strip of thin sheet metal, the edge portions of which are bent reversely onto the back side thereof, covering the face side there-- of with a strip of suitable cushioning fabric, the edge portions of which are extended about the reversely bent portions of the core and clamped between the edges thereof and the adjacent side of the core, the intermediate portion of the core being bent in transversely concave formation on its face side, and a cushioning. shim strip being preferably provided in the cavity thus formed between the fabric and the core.

For a more complete disclosure of the invention reference is made to the following specification in connection with the accompanying drawing, in which:

Fig. 1 is a combined cross-sectional and perspective view, on an enlarged scale, of a channel lining embodying my invention.

Fig. 2 is a cross sectional view of a window channel in which the lining is installed and Fig. 3 is a view, similar to Fig. 1, showing the lining strip in bent formation.

In the drawing, a common form of window frame a is indicated having a deep channel therein to the sides of which an embodiment of my invention is applied.

According to my invention I provide a core I), which consists of a narrow strip of thin sheet metal of uniform width, both edge portions 0, c of which are bent, or rolled reversely in cylindrical form onto the back side of the strip and the middle portion of which between said edge portions is bent in transversely concave form, at its face side, the reversely bent portions being slightly off set to form a sharp bend or angle between the cylindrical portion and the concave middle portion, as indicated at d, d.

A cushioning strip e, of suitable fabric, such as plush, or velvet, having a pile of suitable length, is arranged on the face side of the core and its edge portions are extended about the reversely bent portions 0, c and between the edges of said portions and the back side of the strip, at the apex of each angular portion d, d, and the fabric is securely clamped therebetween and stretched tightly between the rounded surfaces of the portions c, c. On account of the formation of the core above described, there is a substantial space, or longitudinal groove, between the inner side of the fabric and the concave side of the core, in which a reinforcing cushioning strip or shim strip 1 is preferably located, although the use thereof is not essential, as the fabric may be drawn from one edge of the core to the other sufficiently tightly to provide the desired cushioning effect, which depends principally on the height and strength of the pile of the fabric. If the shim strip is employed a less expensive fabric usually may be employed and when the shim strip is employed the longitudinal cavity in the core will hold' the strip in position without other securing means.

The concave-convex formation of the core is advantageous for several reasons. It increases the rigidity of the strip in resisting bending in directions perpendicular to the plane of the strip, so that when the strip is bent edgewise to conform to the curvature of a window frame, it is much less likely to become distorted. Also this formation enables the edgewise bending to be more easily performed, as there is practically no flat surface in the plane of bending. When the strip is bent, the concavity of the core is slightly increased and the width of the core is corespondingly reduced.

By providing the relatively sharp angular portions in the core against which the fabric is clamped by the edge of the core the effectiveness of the clamping action on the fabric is increased. If the strip is secured in position by rivets passing through the middle of the strip the heads of the rivets may be depressed well below the surface of the fabric, so that possibility of chattering against the glass will be avoided.

I claim:

1. A window glass channel lining comprising a core consisting of a narrow strip of sheet metal of uniform width having both of its longitudinal edge portions bent reversely onto its back side and a strip of cushioning fabric on the face side of saidcore having its corresponding edge portions extending about said reversely bent portions and clamped between the edges thereof and the back side of the core, the face side of said core between said reversely bent portions being transversely concave, forming a longitudinal recess over which said fabric is tightly drawn, the lining strip thus formed being adapted to be bent in having its corresponding edge portions extending about said reversely bent portions and clamped between the edges thereof and the back side of the core, the face side of the core between its reversely bent portions being transversely concave, forming a longitudinal recess, and a strip of cushioning material disposed in said recess beneath the fabric, the lining strip thus formed being bendable in curved formation in the plane of its sides.

3. A window glass channel lining comprising a core consisting of a sheet metal strip of uniform width having both of its edge portions bent reversely in cylindrical formation with the edges thereof in proximity to its back side, said edge portions being ofl-set with relation to the middle portion of the strip to provide a relatively sharp angular portion therebetween and a cushioning strip on the face side of said-core having its edge portions extended about said core edge portions and clamped between the edges of the latter and the apex of the corresponding angular portion at the back side of the core.
