959 935. Specification of Letters Patent. Patented lIay 31, 1910.

Application filed August 1, 1908. Serial No. 446,469.

This section is taken in the plane of the dotted line 14, 14, of Fig. 13.

I will now proceed to describe my invention in detail.

The usual headblock plate 1 is present.

T 0 all whom "it may concern:

This extension iron 2 from the of the perch extensions shown in Fig. 13. l point- E at a distance to the right of where it crosses the fifth wheel rearward is thicle ened into a strong body of metal, forming the part 3, which latter preferably extends to the rear side of the fifth wheel. There are usually two of such perch front extension irons 2, and both are symmetrical, being made substantially as hereinbefore described. Each of these front extensions 2, 2 are braced as follows: From the rear por tion of the upper fifth wheel, a lug B extends forward and this lug B is connected by a bolt 18 to the adjacent strong portion 8 of the front perch extension 2. Thus each of said extensions 2 is connected to its own and separate lug B from the upper half of the fifth wheel. To the under side of the portion 3 of each front extension 2 is con nected a brace B, and this brace is connected to the said extension 2 by a bolt and preferably the bolt B aforesaid is made to extend down through the lug B and through the portion 3 of the said perch extension 2,

and through the under brace B and is there provided with a nut B or the lower end of this bolt is there provided with a rivet head in place of the nut. Said rivet head being a well known equivalent of the nut, a sketch of it is omitted from the drawing. The two braces B, one from each perch extension 2, extend downward and forward and are preferably united at their front ends in the part B which latter constitutes an eye or sleeve through which the king bolt 16 passes. This king bolt may be riveted in place below the eye B", but it is preferably provided with the nut 18. Thus this fifth wheel structure is made strong and durable, and can be produced economically. The important fea tures of this portion of my invention consist of four characteristics, viz: First, the changing of the locations of the upper brace and of the lower brace so that they shall both meet the front perch extension forward of the fifth wheel; secondly, so that they shall meet at substantially the same vertical line respectively above and below this perch extension, and thirdly, that the front perch extension shall be made heavier here, namely: at part 3 where they are to join it, and fourthly, as a preferable mode of uniting these braces and the said front perch extension iron, a single bolt therethrough. This changing of the place where the lugs and other braces make connection with the fifth wheel from the outside to the inside of the said wheel concentrates all strains arising from their connections with the fifth wheel to a point where I easily provide a larger body of metal. This concentration of strain, as specified, is not only obviously advantageous but by this change I allow more scope for the free action of the perch back of the said fifth wheel, and also greatly increase the strength of the combined structure of the fifth wheel. The presence of a twisting and the single bolt B to connect a perch extension to the fifth wheel by the lug B above and to the brace B below by the same lug B through this enlarged portion 3 of the extension 2, said enlarged portion located as described relative to the parts heretofore mentioned, is also a feature of my improved construction. The rear free ends of these front perch extensions 2, 2 may be formed to receive perches of various shapes and constructions. In the present illustrative drawings, I have shown a novel and useful formation of these rear ends of the front perch extensions 2, 2, adapted to receive and most successfully hold together perches of which the one hereinafter described is generally typical, without damage to any one of the parts entering into this union by the cutting or breakage of any of the said parts. A description of this perch will be hereinafter presented.

The front end portion of the part 4 has centrally formed thereon a downwardly ex tending centrally located flange 8, and preferably ascending from the highest central point up in each direction of its length until it loses itself in this perch extension 2 proper. The rear portion of each part 4 of such extension 2 is beveled or cut away, preferably on the under side as shown.

I have found by experience that the perch extension irons are vey liable to break at their junction with the perch proper, at the front end of the perch and also at the rear end of the perch. The side thrust and the vertical thrust of the vehicle gear caused in traveling over a rough road wrench the perch and the perch extension in both of their directions, but as, on account of the inequality of the road, the axle of the hind wheel is often in a different plane relative to the horizontal from what the axle of the front wheel is, there is a twisting strain imparted to the perch and to its front and rear connections. To provide against this strain, I locate the bolt horizontally in connecting the perch to its extension iron. I preferably employ but a single bolt, and I strengthen the perch extension iron at and before and behind where this hole for the bolt goes through the extension by a reinforcement, preferably of the peculiar form shown, lo cated beneath the extension and indicated by the numeral 8. I also provide a construction of the combination of the perch, perch extension and bolt, so that these several strains, namely: the vertical, the side, the oscillatory, to which the connection between the perch and the perch connection is subject, shall prevent breakage of the parts at this connection, and shall prevent the perch from shearing in two the connecting bolt of these parts. To this end, I form a horizontal hole 6 through the perch extension. In this hole next where the head 23 of the bolt 22 comes, I countersink this hole thus forming the countersunk portion 7. I form a hole, one through each side of the perch H, viz: a hole 19 through that side of the perch H next the bolt head 23, and a hole 20 in the other side of the perch. I countersink the edge of the hole 19, thereby forming the countersunk portion 21. This countersunk portion 21 I adapt in manufacture to enter the countersunk portion 7 of the perch extension 4.

The perch extension iron is located within the perch iron II; the adjacent end of the perch comes to line 25, where there is preferably a shoulder formed on the perch extension. Against this shoulder 25 the end of the perch abuts. The holes 19 and 20 of the perch register with the hole 6 of the perch. The countersink 21 of the perch is now formed and extends into the counter sunk part 7 of the perch extension. The bolt 2 is now inserted here through the perch and the extension. The bevel of the bolt head 23 fits and rests in the countersink 21 of the perch. The other end of the bolt projects at the other outer side of the perch and its threaded end receives the nut Of course this end of the bolt may have a rivet formation, not shown because well understood, but the nut is preferable. One of the obvious advantages of this formation that I will here repeat, consists of the fact that the presence of that countersunk portion 21 of the perch which is inserted in the countersunk recess 7 of the perch extension, resists tensile strain and prevents a shearing action that would operate to cut the bolt. This single bolt at the same time constitutes a pivot for the vibratory action of the perch.

It will be understood that all of that portion of the perch extension between the free end or tip T and the shoulder 25 is preferably used as a part of the rear perch extension.

The rear perch extension is provided with a portion 26. In this part 26 is a recess 30, adapted to receive the rear axle, the latter in practice there resting upon the part 26. Hole 28 is formed through part 26 at one side of the recess 30 and hole 32 through the part 26 at the other side of the recess 30. hen the rear axle is in place a clip embraces its upper portion. The legs of the clip pass down one on each side of the axle, and respectively pass through the adjacent holes 28 and 32 of the rear perch extension, and each leg is secured by nuts, screwed onto its lower end. As this axle and these clips and the mode of securing them are old, all illustration of them and further description of them is omitted.

IVhen the perch has a metal bottom piece which fits the shell 14 of the perch, such bottom piece will preferably stop at that i i ii end of the reinforcement 8 which is nearest to it, said bottom.

The interior of the perch will usually be filled with a wooden or equivalent filler L, and the part 4, 5, of the perch extension will extend into the metal shell 14 of the perch and along side of, that is, preferably on top of the wooden filler, the latter being formed with an inclined face, to fit the extension 4, 5, substantially as shown in Fig. 10.

In the perch presented, a very strong construction is illustrated. It consists of the shell solid on three sides and provided on its fourth or under side with the reentering parts or edge flanges 15, 15.

The bottom K of the perch is a sheet of metal corrugated in the direction of its length, and having the convex central corrugation 17 and the concave corrugations 16, 16, one on each side of the central corrugations 17. Each concave corrugation extends into a downwardly extending flange 18. Each of these flanges 18 overlaps and rests upon the adjacent edge flange 15 of the main shell I-I. Thus the shell H and the bottom K embracing the wood L, constitute a very strong and elastic reach, and which can withstand much torsional as well as transverse and longitudinal strain. This perch H, L, K is presented in an application for Letters Patent of the United States for swiveled running gear, filed October 19, 1907, Serial Number 398,206, but the novel and efficient mode of combining it with perch extensions, and also with perch extensions of the novel form before described in this present specification are absent from said application Serial Number 398,206. hen the adjacent shell H of the perch is fitted onto the end of the perch extension iron M, it does, as mentioned, go over and on this iron up to the shoulder 25. In this connection it should be noted that the recesses 34, 34, one on each side of the perch reinforcement 8, each receives one of the curved flanges 15, 15 of the perch. Likewise the depressions 33, 33 of this perch extension iron respectively receive the curved portions 16, 16 of the bottom of the perch. Thus the union of these parts is close and compact. The vertical reinforcement 8 strengthens the perch extension at the point where the strain of the union of the perch and the extension, (namely: at and near the bolt 22) occurs.

It will be understood that those portions of the perch extension which include an enlarged portion 3 in the front perch extension and 26 in the rear perch extension, and include the portion 4, beveled at 5, and countersunk with the hole at 6, 7, and reinforced at 8 and provided with shoulder 25 are equally applicable as the front perch extension or as the rear perch extension. When used as a rear perch extension, the

&

top portion of part 3 is transversely grooved at 30, as shown, to receive the rear axle. The combinations shown in Fig. 7 and in Fig. 10 are also equally applicable to the perch extension at front and rear.

If desired to adapt the invention to the various running gear or portions thereof on the market, changes may be resorted to without departing from the spirit of this invention.

Obviously some features of this invention may be used without others.

It should be mentioned that in the fifth wheel shown on the drawings, the upper half B of the fifth wheel has at its rear a lug B extending forward. The lower half C of the fifth wheel carries at rear a brace having a vertical port-ion B and a bottom portion 13. This latter is connected to the said lower half C of the fifth wheel by a screw 13. A bolt B having a head B secures the lug B to the brace B 13. But as this lug 13 and the brace B B screw B and bolt B are old and form no part of this invention, I have not given any further description of them.
