SPECIFICATION forming part of Letters Patent No. 390.872. dated October 9, 1888.

Serial No. 267.727. (No mmlel.)

To LZZ whom, it may concern.' A

Be it known that l, TARGE G. MANDT, a citizen of the United States, and a resident of Stoughton, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Running- Gears for Vehicles; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of the under side of my improved runninggear for vehicles complete. Fig. 2 is a perspective detail view of one of the houndplates, showing the peculiar shoe whereby it is attached to the axles.

the clip on thc front axle, and Fig. 4 is a similar section through the clip on the rear axle.

Like letters of reference denote corresponding parts in the several figures.

My invention has relation to the runninggear of vehicles; and it consists in the detail, construction, and combination of parts of a running-gear, made ot'iron or steel, and adapted to be used in combination with my iniproved compound reach and tongue, which said improvements form the subject of two separate applications for patents of even ldate herewith.

In the accompanying two sheets of drawings, the letter A denotes the reach, which is preferably, though not necessarily,constructed as described in my application for patent hereinbefore referred to.

B denotes the reach-coupling for adjusting the distance between the front and hind axle, and this coupling is preferably, though not necessarily, constructed as described by me in my Letters Patent No. 194,160, bearing date of August 14, 187 7 The letters C and D denote, respectively, the front axle and the rear axle, which may be of any desired construction, and E denotes the sand-bar.

F denotes the front bolster, and G the rear bolster, all of which may be of any desired construction.

The hounds H of the front axle are constructed of angle-iron or steel, in a single piece bent into.a horseshoe shape, as shown on the drawings, their forward ends, H', projecting in front of the axle, where they are connected by means ofthe drawbolt I, upon which the tongue is hinged. The rearwardly-projecting part of the hounds bears against the friction-roller J, journaled in the under side of the reach, and the opposite sides of the horseshoeshaped hounds are locked rmly in place between the axle and the sand-bar by means of the clips K, the under side of the sand-bar being recessed to accommodate the horizontal flange of the hound, so that this flange shall be flush or even with the under side of the sand-bar. y

In order to tix the hound firmly upon the axle, I bolt or rivet upon that part of the hound which comes immediately above the axle and is to be secured thereto apeculiarlyshaped shoe, L, the shape and construction of which are illustrated in Fig. 2 ofthe drawings, and also shown in its application in Fig. 3. By reference to these figures it will be seen that this shoe consists of a plate or casting having a fiat part or plate, M, which is bolted or riveted to the downwardly-proj ectiug flange of the hound iron, and another part or plate, N, projecting at right angles therefrom, so as to overlap the horizontal houndtlange, and this projecting and overlapping part N is provided at opposite ends with downwardly-projeeting anges u a, the length of the projection N between said downwardly-projecting flan ges corresponding to the width of the axle, so that when the hound-iron is placed in position upon the same the dat part or plate N will rest against the upper side of the axle, in which position it is held in place by its downwardly-projecting Bauges n n, as will appear more clearly by reference to Fig. 3 of the drawings. The shoe having been placed in this position upon the axle, the opposite legs of the clip O (see Fig. 4) are inserted through holes bored in the horizontal flange of the hound-iron, so as to straddle the axle on 0pposite sides in the usual manner, in which p0- sition the clip is locked in place,so as to firmly bind the sand-bar, hounds, and axles by means of the usual clip plate, P, and nuts Q Q. In order to further strengthen these several parts and interlock them still more tirmly,I further employ, at each end of the axle and over each ICO clip-plate, a steel brace, R, which is bolted to the under side of the horizontal flange of the hound-iron on opposite sides ofthe axle, after it has been first bent over the under side of the axle, so as to clamp the clipplate against the axle, as shown in Fig. 4. Thus it will be seen that this brace R, of which there is one on each side, serves not only to raise and stiften both the forwardly and rearwardly projecting parts ofthe hound-iron,but also serves as an additional means for looking the clip O and clip-plate P in position, so as to firmly nnitethe sand-bar, hound-iron, and axle. In this manner I obtain `the greatest possible strength, durability, and rigidity in the front part of the running-gear without unduly increasing the weight of the same or complicating its parts.

The rear part of the running-gear, or that part which is attached to and forms a part of the rear axle,D, is constructed in subsi antially the same manner, though of course the parts are cfa dilierent shape-lhat is to say, the angle-irons which i'orm the hounds are not in a single piece, as in the case of the front hounds, but are constructed of' two separate angle-shaped steel bars, (denoted by the letters S SJ the forward ends of which are connected by the clamping device or coupling B, while their diverging rear ends are provided with shoes L', the construction and arrangement of which are in all respects similar to the shoes L,wherehy the front hounds are fastened upon the front anxle. The rear axle and its bolster are locked together by means of clips E in precisely the same manner as the front axle and sandbar; but the rear braces, R', do not extend across the under side of the rear axle, but are cut oif behind the rearmost clip-nut, as will appear by reference to Figs l and 3 of the drawings. In other respects the construction, arrangement, and combination of the rear hounds, the rear bolster, and rear axle are in all respects the same as that which has been already described in describing the con struction,arrangerneut,and combination of the front hounds, sandbar, and front axle with their clips.

In order to further sti'ien and strengthen the running-gear, as awhole, at such points where additional stiffness may be required, I employ a system of bracerods, T, the arrangement of which of course depends upon the particular type of wagon manufactured. By the peculiar construction and arrangement of the front and rear hounds and their combination with the axles, clips, and clip-plates, as hereinbefore described, I produce a running-gear which, while very light, (especially where steel is employed in the manufacture ofthe hound-irons and braces, yet possesses i m mense strength and rigidity, and, as a consequence thereof', great durability. I employ no superfluous parts, but, it will be seen, make mostof the parts of my improved running-gear serve a twofold and sometimes a threefold purpose.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a running-gear for vehicles, the combination of the following elements: the front axle, the horseshoe-shaped hounds or houndirons, made of augleiron or steel, in a single piece, the sandbar, the clips, and the braces bearing against the clip-plates and fastened to the under side of the hound-iron ou opposite sides of the axle, substantially as shown and set forth.

2. As an article of manufacture, 'the houndirons, made oi'angle-iron or steel and provided with the shoes L, adapted to bear against and interlock with the axle, substantially as shown and set forth.

3. The combination, in the running'gear of vehicles, of the axle, the hounds provided with the shoe L, and the clips, substantially as and for the purpose shown and set forth.

4. The combination of the hind axle, the honndirons S S, constructed as described, the shoes L', the clips, and the bolster, all construeted and combined substantially as and for the purpose shown and set forth.

5. The combination of the hind axle, the houndirons, constructed as described, the shoes fastened upon said irons, the clips, the bolster, and the braces R', all constructed and combined substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto at'iixed my signature in presence oi' two witnesses.

TARGE G. MANDT.
