T will now proceed to describe my invention in detail. The particular construction of the front axle bar, and of the headblock and of the king bolt and of those parts of the fifth wheel which are close to this front axle may be varied as desired. Such particular constructimi forms no portion of my invention. All that is necessary in relation to this construction is that the fifth wheel and any braces it may have shall in some proper manner be connected to the swivel connection hereinafter mentioned, which constitutes one of the features of my invention, namely: a feature which shall enable the reach to accommodate itself to the varying side thrusts and to the varying vertical thrusts to which the gear of :1 ve hicle, especially the gear of a road vehicle, is constantly subjected.

I wish it to be understood that my invention is applicable not only to a system of front and rear cross springs, as shown, but also to other descriptions of spring platforms and of other kinds of springs combined with the running gear of the vehicle.

For the purposes of the illustration of my invention, l have shown and shall dc scribe one of the various kinds of front ci'mstruction of the running gear to which my invention is applicable.

A indicates the front axle, of which one portion A is of iron and the other portion A is of wood, as is connnonly the manner in which such axles are now made.

C is a transverse cross spring mounted on the ordinary headblock D.

The fifth wheel E has the usual lower segment E and the upper segment E". The respective ends of the upper segment E are secured to the headblock D at the under side of the respective end portions, the usual frame piece F and bolts D D respectively passing through these end portions of this upper segment F1 of the fifth wheel, and through this frame piece F and through the headblock D.

The lower segn'ient FF of the fifth wheel is connected at its ends to the axle A rethe bearing L spectively by means of clips G whose respective straps G lie under the axle A. At the midlength of the axle is a piece (brace) H whose strap H passes down over the front side of the axle and is there connected to a tie piece H which extends under the axle A, and terminates in the enlarged portion H The front connection of this strap H to the tie piece}? is the nut H.

At the rear side of the axle A is the king bolt K. The upper end of this bolt is rigidly secured to the headblock D by a bolt K This king bolt K passes down through the frame piece F and through the piece H, and through the rear thickened portion H of the tie piece H and through the front end L of the forked brace L. A screw thread on the lower portion of the king bolt K below the brace L is engaged by a nut K The brace end L has an upward extension bearing L which fits a recess H in the piece H of the tie strap.

The axle A and its piece H, H tie H and piece H as one turn and revolve around the kingbolt K, the piece H rotating on As the lower segment E of the fifth wheel E is rigidly connected to the axle it also turns therewith. Thus while the headblock and the upper segment of the fifth wheel segment is stationary relative to the length of the running gear, the lower segment rotates with the front axle as the latter is moved to cause the vehicle to make a turn 011 the road. In the illus trative instance, the braces M, M, are connected at one end to the headblock D, preferably by being connected to the frame piece F aforementioned. This frame piece F is connected to the headblock by the clips C C the latter being secured to said piece by nuts C in the usual manner.

The forked brace L, from the part L already mentioned, diverges in two branches L L All the constructions relative to the front portion, and thus far described, are old and well known in the state of the art.

It has been customary to unite the braces M, M, and the forks or branches L L rigidly in some manner to the reaches of the vehicle.

One of the features of my invention consists of new and useful means connecting the front headblock through the medium of such braces and branches or their equivalent to the reaches or perches of the vehicle, whereby the front portion of the vehicle may change its horizontal plane relative to the rear portion of the vehicle, and vice versa. The means are substantially as follows:

N indicates a bolt sleeve, connected rigidly to the said braces M, M, and to the branches L L Preferably the sleeve N is integral with the braces M, M, and the branches L L are bolted to the said braces M, M. This socket N is thereby held rigidly in position with the front axle A.

P indicates another portion of a bolt sleeve. This portion P is rigidly connected to the forward end of the reaches R, R.

O is a bolt having an enlarged portion 0 and a terminal head or flange 0 posite end of the bolt is provided with a screw thread 0 When combined, the enlarged portion 0 of the bolt is located in the sleeve P, and the shank O of the bolt in the sleeve N. The shoulder 0 between the enlarged portion 0 and the smaller shank O rests against the rear end of the sleeve N. Between the socket P and the socket N is located a washer Q, to avoid the wear of the sleeve and to reduce friction. On the screw threaded portion 0 of the shank O is a nut 0 which holds the sleeve N closely to the washer Q and the sleeve P. Anannular flange P is preferably present on the sleeve P, and this flange covers the periphery of the washer Q and extends over the periphery of the adjacent portion of the sleeve N. Thus I exclude dust and dirt from the washer Q and from the joint between the sleeves P and N.

It is apparent that the reaches R, R, and the rear axle B can move in a rotatory manner, that is, in a direction around the midlength of the vehicle as an axis. This capacity for such movement obviates all torsional strain ordinarily present when the reaches are fastened rigidly in every direction to the headblock, or its intermediate rigid connections between the headblock and the reaches.

The preferred kind of reaches present and their preferred connection with the sleeve constitute other features of my invention,

and are as follows: The sleeve P is made in one with the arms P P extending out at right angles to the axis of this sleeve P. These arms P P respectively terminate in the arms P P Each of these arms connects with an adjacent portion of the adjacent reach. Each arm P tapers as shown, and is received in the shell of a reach consisting of a metal shell or shells, embracing a cen tral portion or filler S of wood. The kind of shell shown herein is that which forms the The opexterior top and sides of the reach and is indicated by the character T. The exterior bottom U of the reach is a sheet of metal corrugated in the direction of its length and having the central corrugation U and the curves U extending from the bottom edges of the central corrugation up over and outward and down, see Fig. 4. The bottom edges of the shell T respectively extend inwardly under the curved portions U of the bottom U and then upwardly forming the flanges T T Thus the shell T and bottom U embracing the wood Within constitute a very strong and elastic reach, and

which can withstand much torsional as well as transverse and longitudinal strain, although it is true, that my swiveled joint aforementioned relieves my reaches of torsional strain.

Each extension arm P of its arm P extends under the shell T and upon the wood S, and is bolted thereto by the rear one of the bolts V, V, passing through these parts, and its nut V below screwed there to said bolt. A similar bolt V and its nut V sccures the forward end of the shell T to the arm I.

The rear ends of the reaches R, B, may be connected to the rear axle B without any additional device or strengthening means, but I prefer to combine with the rear end of each reach a heel iron 7 having a shank V which so far as it is present takes the place of the wood S of the reach. A head. has shoulders 7* projecting respectively beyond the sides of the shank. These shoulders set against the shell T and regulate the distance this heel iron may be driven into the reach. l/Vhen the heel iron and the reach are united, they are combined as shown in Fig. 9. The upper side or top of the adjacent end portion of the reach is flattened, see Fig. 7, to enable it to be brought up closely against the under side of the rear axle.

A clip X, seated on the axle B, secures the heel end of the reach to the axle. One of the rods of the clips passes through the hole W of the heel iron \/V and the other rod passes through the hole T of the reach (Figs. 7 and 9) and the hole W of the heel iron IV. Nuts respectively screwed to said rods secure the latter in place, and the reach with its heel iron to the axle. The union between the heel iron WV and the reach is made stronger by providing the heel iron with the tapered extension pieces V lV constituting a fork, see Fig. 8. The wood S enters the space between the forked portions 7 7 and the latter extend along the sides of the wood within the shell.

A convenient chair or saddle piece Y having a flat bottom and a curved top Y and open ended slots Y, Y*, may be employed to adapt the top of the reach to receive the axle B, in cases where the under side of the axle is rounded in cross section. Y are preferably open ended. The axle B sets in the recess Y upon this chair. The

' chair sets on the flat end of the reach, and

the clip rods respectively pass through the slots Y Y before passing down through the holes in the heel iron and reach as aforesaid.

In the illustrative drawing, Fig. 1, the axle B is compound, consisting of an iron portion B and a wooden upper portion B A spring Z upon the axle is clipped thereto by the customary clips Z Z The rear por- The slots Y l tion of the reaches R, B, may be braced by braces B*, one for each reach, extending from the outer portion of the axle B to the reach and there united at B by a clip or other suitable fastening.

It is understood that the wood S of the reach is preferably integral from end to end, thereby adding much strength to the reach to resist transverse strains.
