Specification of Letters Patent.

iatented July 17, 1906.

To all whom, it mag concern.-

Be it known that we, ENOCH DEMSKY and CHARLES RnnncKER, citizens of the United States, residing at St. Louis, Missouri, have invented a new and useful Vehicle-Body, of which the following is a specification.

This invention relates to the construction of vehicle-bodies; and it consists of various improvements which are fully shown in the accompanying drawings, which form part of this specification.

Previous efforts of manufacturers to produce a vehicle-body which will withstand all variations of weather conditions and maintain a smooth and unbroken surface have, so far as known, met with failure. The panels have usually been fastened in place by nails or screws or similar fastening devices, which pass through the panels, the heads of such devices usually resting in countersinks in the panels and being covered over flush with the surface of the panel by plugs of various kinds. Such expedients are ineffective for permanent smoothness, and, as is well known, therigors of climatic variations have a telling efl'ect thereon, resulting eventually in a perceptible line of cleavage or demarcation between the panel and the plug, and finally the latter may drop out. In'any event the line of demarcation is unsightly and results in a permanent defacement which destroys the artistic finish of the vehicle-body.

Other eXpedients have been resorted tosuch, for instance, as dovetailing the panels to the posts or uprights; but perfect fit is dlfficult to secure, and especially so as the l ooves and tongues for each panel must all e parallel in order to render possible the po sitioning of the panels. Therefore, in view of the well-known fact that most vehicle-bodies flare outward at the top and that the posts or uprights must also lean outward, it is in such cases impossible to make the dovetails on the posts or uprights parallel, and the inadequacy of this method of fastening the panels is evident.

V Staples or bent metal wedges are impracticable for various reasons, prominent among which is the fact that they could only bind the edges of the panel and the middle portion would war To avoid all the aforesaid diificulties an to produce a strong, durable, and

adequate fastening device, one that can be used on all shapes of vehicle-bodies, Whether flaring or not, and that efliciently binds the panel at allnecessary places without in any manner defacing the exterior surface of the panels, is the obj eot of our resent invention. In the accompanying awings, wherein our invention isillustrated, Figure 1 is a perspective View of a vehicle-body partially assembled, showing the application of our invention. Fig. 2 is a vertical section ofa panel and 1post, showing the fastening attachment in p ace Fig. 3 is a cross-section of a panel and sill with the fastening device therein. Fig. 4 is a bottom view of a vehicle-body constructed in accordance with our invention. Figs. 5, 6, and 7 are views illustrative of the various stages or steps passed through in the practice of our invention. 7

r The general principles of our invention are illustrated in Figs. 5, 6, and 7, wherein are shown two objects in the various stages from their relationas separate pieces until they are united and fastened together.- The fastoning member employed consists of a long piece of thin metal 1, provided on its edges with lateral arallel projections 2, the preferred form eing one in which the projections extend both ways, thereby forming an I-beam, which form is shown in the various figures of the drawings. The piece 3, of wood, and the piece 4, also of wood, Fig. 5, are to be fastened together. In said piece 3 a saw kerf or groove 5 is formed, and a corresponding kerf or groove 6 is formed in the piece 4, the kerfs or grooves being of substantially e ual depth and in width e ual to or slightly ess than the thickness of t e web of beam 1 and their combined depth equal to the depth of the said beam 1. A coat of glue (showing at 7 in Figs. 6 and 7 is then placed on one of the pieces, and they are then brought together so that the .two kerfs or grooves 5 and 6 register, thereby forming a single continuous passage-way as faras they run.- The pieces are then ready for the application of the fastening member comprising the flanged beam 1. Said beam is thereupon driven into the passage-way formed by said kerfs or grooves, and the flanges 2 embed themselves into the sides of said passage-way, asclearly shown in Fig. 7, thereby firmly uniting the two pieces si ts in the formation of registering kerfs or grooves in the uprights and, if desired,in the sill and the formation of registering kerfs or grooves in the panels, gluing the panels onto the uprights and sills and driving the fastening devices into the passage-ways formed by the said kerfs or grooves.

As shown, the numeral 8 indicates the sill of the frame. 9 indicates the corner posts or uprights, and 10 the uprights which are under the seat, the up er ends of the last-named uprights at each side being joined by a brace 1 1. :In the outer faces of the corner-uprights are formed kerfs or grooves 12, which may or may not extend throughout the length thereof, and similar kerfs or grooves 13 are formed in the outer faces of the uprights 10, which are longer than those at the corners. I At the ends of the panels15 kerfs or grooves 16 are formed in such position that they register with those in the corner-uprights when the panels are glued in position. Likewise kerfs or grooves 17 are formed in the inner faces of the side panels across both pieces 15 and 15*, constituting each panel, in such position that they register with the kerfs or grooves 13 in the uprights 10. At intervals along the sills 8 kerfs or grooves 18 may be formed; but these should not extend entirely across the outer face of the sills, but should leave the upper surface of the sills intact, so that moisture cannot enter. Similar registering kerfs 19 are formed in the panels. Kerfs 20 are formed in the braces 11 and similar registering kerfs 21 in the upper portions 15 of the panels.

After the various kerfs or grooves have been formed glue is placed upon the frame or upon the panels, and the panels are then placed in position. If desired or found advantageous, the panels can be clamped and so held firmly in position until the entire body is finished or as long as necessary. While so held long fastening devices 31, preferably in I-beam form, as described, are driven into the passages formed by the kerfs 12 and 16 at the ends of the panels and also into'the passages formed by the kerfs 13 and 17 at the center. The assage-ways, as heretofore described, shou d be smaller than the Ibearns, so that they will bind firmly therein. The flanges 32 embed themselves in the wood. It is preferred that the fastening devices in the uprights shall extend the full length thereof and also the full width of the panels, so that the latter will be firmly and securely held against warping; but, as indicated in dotted lines in Fig. 2, a shorter fastener may be driven into each end of the passage-Way, and if too much'space be not left such arrangement will suffice. By his system of fastening the panels it is apparent that the separate upper portions 15* will be more firmly, securely, and fixedly held in place on the main portion 15 than could possibly be by employing screws or nails or the like or even if the panels were dovetailed onto the uprights.

In the passages 18 19 short fasteners are driven, as indicated at 22 in Fig. 3. These do not extend all the way through the sills, but leave the upper surface of the sill unbroken, so that the panels fit flush against the upper edges of the sills all along, thereby forming a more perfect and an unbroken joint. In the passages 20 21 fasteners are also driven, as shown at 23 in Fig. 1, and by said fasteners 22 and 23 the edges of the side panels will be securely held. The lower edges of the end panels are also held by fasteners 22, as shown in Fig. 4. Fasteners of this character are vastly superior to nails, screws, or plugs, because there is no defacement of the finished exterior of the panels.

and for the further reason that a contlnuous bond is formed as far as the I-beams extend, and they may bemade to extend entirely across the panels transversely of the grain thereof, so that warping is absolutely impossible. No shrinkage or loosening of the panels occurs, as so frequently happens when simple dovetailing of the panels onto the uprights is the fastening method employed. All portions ofthe panels will be held with equal rigidity against the uprights, and the lower edges are firmly bound by the short fasteners there. Moreover, in the present system of screwing the panels onto the frames several days are required in which to finish a vehicle-body; but by this method of fastening the panels the entire body can be completed within a few hours, thereby hastening the manufacture and enabling the manufacturer to produce a superior article in less time and at reduced cost.

We are aware that there may be variations or modifications from the details herein described without in the least departing from the spirit and scope of the invention, and we do not wish to be understood as restricting ourselves to exact details; but,

Having described the invention, what we ITO do claim, and desire to secure by Letters Patinto said registering kerfs when said adhesive substance is pliable, the flanges of said locking member being embedded into both sides and near the bottoms of each kerf, substantially as described.

3. In a vehicle-body construction, a post and a panel, each provided with a registering kerf, and a flanged locking member I- shaped in cross-section Whose de th is substantially equalto the combine said registering kerfs, said locking member being driven into the registering ker fs, the

depths of flanges thereof forming their own seats and being embedded into both sides and at the bottom of each kerf; substantially as de- 15 scribed.

In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
