D. C. BAILEY WINDOW GLASS GUIDE Nov. 10, 1936.

Filed June 14, 1955 :55 in Fig. 7.

Patented Nov. 10, 1936 UNITED STATES lATENT OFFICE 8 Claims.

This invention relates to that class of window glass guides generally used in automobile bodies, which are so constructed that they may be bent to an extent suilicient to enable them to be conformed to the curvature of the window frames in which the glass is mounted, an example of which is shown in my prior Patent No. 1,963,541 of April 1, 1933.

While the construction of said patent has been extensively employed and is satisfactory in many respects, yet there is a constant demand that costs be reduced, and, on account of the fact that some looseness must be permitted between the ends of the tongues formed in the sides of the channel and the edge beads, to permit movement of the tongues therein when the channel is bent, some difficulty has been encountered in mass production due to the fact that the edge beads sometimes become detached.

The objects of my present invention are to provide a construction of the character above referred to, which may be produced at a somewhat reduced cost, as compared with prior constructions of like character and with which the mechanical difficulty above referred to may be obviated.

I accomplish these objects by means -of the constructions hereinafter described and illustrated in the accompanying drawing, in which:

. Fig. 1 is a side elevation illustrating a form of my'invention installed in a window frame.

Fig. 2 is a view, partly in cross section and partly in perspective, showing a preferred embodiment of my invention.

: Fig. 3 is a cross sectional view of a slightly members each of which consists of a continuous edge portion l2 and a series of suitably spaced tongues I3, which are formed by providing a strip of thin metal of suitable width and cutting through the middle portion thereof in the zigrag manner indicated in Fig. 6, so that the strip is cut into two pieces, each of which is then bent to provide a rolled edge portion I4 on the continuous portion and a right angularly disposed. lip IS on the end of each tongue, as shown I also provide a base strip [6 of uniform width, each edge of which is turned up to provide a narrow flange II, as shown in Fig. 4.. I further provide a base reinforcing strip I8, both edge portions IQ of which are somewhat off-set, as shown in Fig. 5, and the :5, distance between the edges thereof being somewhat less than the distance between the inner sides of the flanges ll.

These parts are then assembled by placing the tongues [3 of the side members against the 10 inner sides of the flanges ll of the base strip 16, with the lips 15 engaged with the inner side of the latter and extending inward and then placing the reinforcing strip I 8 on the inner side of the base strip, so that the off-set portions I9 15 thereof extend over the lips l5, and then attaching the strip I8 to the base strip by spot welding, or other suitable or convenient means, the parts thus being arranged as shown in Fig.

The edge portions of the strips l6 and I8 thus provide continuous grooves or recesses into which the lips l5 extend, the latter being held in position therein by the edge flanges I1, and the parts being so arranged that, while there is no substantial looseness between the tongues of the sides and the base sections, yet a slight sliding movement of the ends of the tongues, 1ongitudinally'of the grooves in which they are located, is permitted.

The inner surface of the channel thus formed is lined with suitable cushioning material, which consists of a strip 26, which may be adhesively connected to the base strip I8, and separate side strips 2|, the edges of which are preferably clamped by the rolled-over edges M of the sides, as shown in Fig. 2. The outer surface of the sides may be partly covered by a narrow strip 22 of textile material, which is clamped by the edge l4 and extends for a short distance towards 40 the bottom of the channel, as shown in Fig. 3.

With the above described construction, when the channel, as thus formed, is bent to conform to a curvedwindow frame or casing, as shown in Fig. l, the rolled edges l4 and the base mem- 5 bers l6 and I8 may be bent sufficiently without difiiculty. Bending of the edges 14 will, however, tend to cause the tongues l3 to be swung from their parallel to radial positions, as shown in Figs.

1 and 10, the lip portions l5 being moved slightly 5 in the grooves formed between the bottom members, so that bending of the sides will be permitted without strain or buckling. The flanges II on the base section [6 are so narrow that, while they tend to prevent bending of this portion of the channel, they do not appreciably affect it. As their only function is to hold the tongues in position in the grooves, the extent to which edge portions are bent to perform this function may be less than that indicated in the drawing. The lips [5 also act to hold the sides in upright positions and after the channel is installed and the glass placed in position, the channel will function as efficiently as any other guide used in this relation.

The strip I 8 also reinforces the base strip 16, so that both may be formed from very thin metal and, as there is no waste of metal in the formation of the sides, an actual saving in metal may be made over my said prior construction.

In Figs. 8 and 9 two modifications of my invention are illustrated. In Fig. 8, a base member 25 is shown the edge portions 26 of which are rolled about reinforcing wires 21, and the side members 28 are provided with tongues 29, as before described, and the end portions 30 of said tongues are bent about the exterior of the rolled or beaded edge portions, so that they are securely held in engagement therewith, but slight-movement of the tongues on the beaded edges of the base member is permitted when the channel is bent, in substantially the same manner as before described in reference to the form shown in Fig. 2. The exterior of the sides are preferably covered with thin textile material 3|, which is adhesively secured to the strip of material before it is cut to form the tongues, as shown in Fig. 6, so that the cloth will be out between adjacent tongues and will not interfere with the bending operation. A narrow textile strip 32 may also be provided on the exterior of the sides similar to the strip 22, in Fig. 3. Cushioning material 33 may also be provided on the inner side of the channel similar to that shown in Figs. 2 and 3.

In the form shown in Fig. 9, the base member 34 is somewhat wider than the previously described constructions and its edge portions are bent inwardly to form inwardly facing grooves 35. The side members are formed as shown in Fig. '7, but, when placed in position, are placed oppositely to the position of Fig. 2, so that the lips 36 at their ends extend into the grooves 35 and are sufliciently loosely engaged therein to permit a slight movement thereof longitudinally of the grooves when the channel is bent. In this instance the base member is shown as covered with textile material 38 and a portion of the outer sides of the side members as partly covered by a narrow strip of similar material 31. Cushioning material for the interior of the channel is provided which is similar to that pre viously described, except that the material 39 on the base member is extended for the full width of the space between the tongues, to hold the latter in engaged position.

The form of channel shown in Fig. 9 is preferably secured in position by setting one of the base flanges formed by the reversely bent portions, into a groove at one side of the casing groove and securing a removable molding over the other base flange.

In both of the last described forms of my invention the action, when the channel is bent, is precisely the same as that already described in connection with the form first described, the tongues of the sides being moved to slightly radial positions with relation to the curvature of the casing, when the channel is bent to conform thereto, as shown in Fig. 10.

These forms are somewhat advantageous over the first described form in that less sheet metal is required for their construction.
