BAILEY, OI AmUBY, IABSAOH'UBETTS, ABSIGNOR TO BAIL OOIPANY, INC, 0] AmUBY, IABBAOHUSBTTS, A CORPORATION 01' KASBAOHUBIT'IS WINDOW GLASS CHANNEL Application am June 1, 193a. semi Io. 615,828.

This invention relates to certain im rovements in window glass guides PliIIlB-ll y intended for use in connection with'the frameless window glass of automobile bodies and particularly to certain improvements in the specific form of guide shown in my pending application, Serial No. 467,184. I

In the construction of many automobile bodies of the closed type the window openings are curved in outline, either partly or wholly, and it is customary, in the construction of metal automobile bodies, to extend the grooves, in which the usual window glass guides are set, continuously from each side across the top of the opening, the to edge of the glass being curved to correspon to the .to curvature of the opening.

his construction necessitates a corresponding bending of the cushioning guide which is placed in the casing groove, and, while guides which do not include metal in their construction may be readily bent, guides which include a U-form metal channel are required for automobiles oi? the higher grade. Certain types of U-form metal channels may be bent by means of special apparatus, but this is usually a difiicult operation to perform, either in the factor where the guides are produced, or in the actory where they are installed. It is, moreover, particularly desirable for the guide manufacturer to be able to ship the guides in straight lengths, so that it is desirable for several reasons that the workmen who install the guides .may bend them readily into the shape desired.

While guides constructed according to the disclosure of my said application are particularly desirable for casmg grooves which are straight, such guides are not only diflicult to bend, but I do not consider it to be feasible to bend them to the. extent now required for curved window casings.

The objects of my invention are to provide a form of window glass guide which will embody the more important features of construction of the guide disclosed in my said application, and which, in addition, will be so constructed that it may be readily shaped onto a form which will correspond to the curvature of any particular window opening in which it is likely to be installed. Also to provide an im roved form of cushioning means which wi 1 be less expensive to manufacture than,and will be at least as efi'ective in its cushioning action as my said previously disclosed guide, and which willbe of nel may be readily bent, said tongues having ornamental beads mounted on the ends thereof which permit relative fiatwise movement of the tongues therein and hold the tongues in alignment under all conditions, and said channel having a textile covering on its exterior, and cushions on its inner sides for engaging the glass, both of'which are secured in position by the beads .and by fastening means passing through the spaces between the tongues.

For a more complete disclosure of the invention reference is now made to the following specification, in connection with the accompanying drawing in which Fig. 1 is a view in side elevation, partly in section, or a portion of a window casing in which an embodiment of my invention is installed.

Fig. 2 is a view on a greatly enlarged scale, partly in cross section and partly in perspective, of asection of the guide prior to installation.

-Fig. 3 is a cross sectional view of the guide on a similar scale, showing the ,glass in position therein.

Figs. 4 and 5 are detail views showing modifications of the invention.

In the drawing a indicates a section of the top portion of the window casing of an automobile body, having a groove in which the usual window glass'guide is secured, the sides of the opening merging with the top portion in a gradual curve.

Ac ording to my invention I provide a U- form channel of thin, readily bendable metal,

which comprises a bottom portion 6, and side portions, each of which comprises a rounded connecting portion 0 and a series of fiat tongues d, said tongues being formed from the sides of the channel strip by cutting out notches, as d, from each side thereof.

Said notches are shown as of approximately the same widths as the tongues, but this arrangement is'not essential to the invention, as the notches may be of less width than the tongues, and instead of the ends of the notches being of square formation, as shown in Figs. 1 and 2, they may be made rounded, or U- shaped, as shown by the notches d 'in Fig. 4, or they may be made V-sha ed, as shown by the notches d in Fig. 5, or they may be made of other shapeswhich will be suitable for the pur ose. The square formation is however pre erable for several reasons, as it enables sheet metal to be cut into strips, suitable to be bent into channel form, by the cutting operation which forms the ton ues, so that no material is wasted by reason 0 the formation of the notches in the sides of the channel, and a straight edge is provided on the end of each tongue to receive the edge bead, as hereafter described.

As best shown in Fig. 2, the end portion of each tongue d is split at the middle for a short distance and the portions thus bifurcated are bent oppositely at right angles to the sides, forming flanges e on the ends of said tongues. A U-form metal head f is then bent about the flanges e of the tongues of each side, to provide the same with continuous finished edges of ornamental material in the manner disclosed in my said application.

Before placing the bead in position, a textile covering 9 is placed about the entire exterior of the metal channel and cemented thereto, and the edge portion of said covering is extended to, and preferably over the ends of the tongues g, as shown. Also, the interior of the channel is covered with a textile lining h, which is also cemented thereto, and a cushioning packing is provided in connection, therewith, which preferably consists of two bundles of wicking z', or like material, about which the lining h is passed, and to which it is secured by means of stitches 7', or other convenient means.

While the covering 9 and lining k may be made of separate pieces of material with the edges thereof terminating beneath, or within the head 7, they are preferably formed of one continuous piece, so that the covering g, after extending over the edges of the channel will be continued about the wicking'i, and along on the inner surface of the channelto form the lining h, as shown in Figs. 2 and 3. The particular meeting point of the edges of the material which forms the covering and lining is not of special importance, but preferably is at the middle of the inner side of the base portion, as

shown. The portion of the material which is engaged by the bead f is somewhat loosely clamped, for reasons which will hereafter appear. The bundles i of wicking will thus be held against the inner sides of the channel in proximity'to the heads 7, and they are made of sufficient diameter to project well beyond the inner sides'of the beads, sov as to hold the glass X out of contact with the beads and provide a suitable cushion for the glass which is placed therebetween, as shown in Fig. 3. To counteract any tendency which the movement of the glass might have to pull the bundles of cushioning material 6 out Ward, a series of fastenings k, which may be in the form of stitches, are passed through the lining h, the notches between the tongues d and through the covering g, securely attaching the lining h to thecovering g. These fastenings may be located at any suitable or convenient points between the cushions 2' and the inner ends of the notches. A strip of felt m, or like material is also preferably secured by a suitable adhesive to the lining it over the meeting edges of the material of which the latter is formed, and in position to be engaged by the edge of the glass.

When the complete guide, as thus constructed is to be installed, it will, or may be in straight sections, and will be cut in lengths to extendthroughout the length of the sides and top of the window opening, when the opening is of the type of that indicated in Fig. 1, so that the sides and top portions are connected by curved portions, the top portions being either curved throughout or part ly curved. The guide is then bent so that its base portion is curved to correspond to the curvature of the bottom of the casing groove, before the strip is inserted, or as it is inserted, to enable the base portion to be fitted closely against the bottom. The bending action thus performed will cause the end portions of the tongues d to be swung towards each other to a slight extent, as shown in Fig. 1, this movement being permitted by the beads f, which are clamped somewhat loosely indirect engagement with the lining and covering and indirect engagement with the ends of the tongues and sides'of the channel thereby permitting a slight movement of the tongues in the beads. The beads, therefore will not be buckled or distorted by the bending action, and, moreover, in bending the channel to conform to the curvature of the casing, there is a strong tendency to cause and prevent the tongues from being bent outof line under all conditions. The beads f, therefore, have important mechanical as well as ornamental functions.

As the net result will be to shorten the length of the guide at the ends of the tongues, when it is bent, without decreasing the length of the beads, the latter will be extended beyond the ends of the guide, at the end of the bending operation, to the extent to which this portion of the guide is shortened. As the covering 9 is secured to the sides of the tongues, so that relative movement thereof is not permitted, the tendency will be to gather or wrinkle the covering to a slight extent, but the fullness or wrinkling thus caused will not detract from the appearance of the guide when installed, as only a small portion of the sides of the guide will then be exposed, and, in many instances, only the beads will be exposed. Any fullness or wrinklin of the covering will usually be received y the spaces betweenthe tongues 1 d, and the slight buckling of the cushioning material 2' will not be apparent from the outside.

When the glass is in position in the guide, it will be effectively cushioned and the cushioning means i will be securely held in position by the lining and covering 9 and h and the fastening means 70, and it will'not be displaced by the withdrawal of the glass from the guide portion which is locatedin the top portion of the window opening.

When installed the guide will present the same finished appearance as that of my said application, although it may be bent into any form which is likely to be required when in stalled.
