SIDE-SPRING BUGGY-GEAR.

SPECIFICATION forming part of Letters Patent No. 236,919, dated January 25, 1881.

Application filed August 16, 1860. (ModeL) To all whom it may concern:

Be it known that we, GEO. W. F. THOMP- SON and FRANK A.'HAYWARD, of Omro, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Side-Spring Buggy-Gear; and we 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 accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a top view of the reach and axle. Fig. 2 is a detail perspective View of the reach, axle, and brace, and the spring-supporting shackle, showing the mode of attachment of the shackle to the axle and reach. Fig. 3 is a perspective view of the enlarged rear end of the brace. Fig. 4 is a perspective view of the strap or staple. Fig. 5 is a similar view of the bearing to which the shackle is hung. Fig. 6 is a perspective view of the shackle.

The same letter indicates the same part wherever it occurs in the drawings.

Our invention relates to improvements in the running-gear of side-spring buggies, having for their object increased strength of reach and axle, an improved mode of coupling the side springs, and increased facility in adjustin g the track of the vehicle.

It consists. in bending the reaches inward in arcs which touch about midway between the axles, continuing them back to unite with the hind axle to form its stock, attaching the axle, reach, and spring-shackle together by means of the staple, brace, and screw-nuts, and uniting the forward ends of the braces to the reaches by screw-bolts, all in the manner hereinafter more specifically set forth.

In the drawings, A marks the hind axletree, which is of ironjB B, the braces; R R, the reaches, and H the head-block.

ThereachesRare made of any suitable tough wood, bent by steaming into the bow shape represented in Fig. 1. Their rear ends lie on top of the axleA, and serve as hind-axle stocks. The reaches come together at the point where the forward ends of the braces B B are attached to them by the screw-bolts b b. The

brace B is enlarged at its rear end (see a a, Figs. 2 and 3) to get a good bearing on top of the reach, and it is provided with holes h h, which receive the screw-tapped ends 8 s of the broad strap or staple D, which binds the reach and axle together. strap passes around the bearing E, having the shape shown in Fig. 5, the lugs e 6 serving to embrace the lower side of the axle, and the groove d receiving the upper round bar, 0, of the shackle G, which is suspended to the hearing E and swings in it. The lower bar, 0 of the shackle receives the end of the side spring of the vehicle, which is attached to it in the ordinary way.

The reach and axle having been placed in proper juxtaposition, the shackle O is placed in its bearing E, and this is adjusted to the lower side of the axle A and confined there by the strap D, the tapped ends of which pass through the holes h h in the enlarged end of brace B, and receive the nuts 12 n, which bind the whole structure firmly together without the use of mortise or tenon or any hole through either axle or reach.

Before bolting the forward ends of the braces to the reaches these may be slightly moved upon each other to adjust the tracking of the vehicle. When this is accomplished the nuts are screwed up to secure the reaches together and brace the hind axle.

The shackles for the forward ends of the side springs are attached to the head-block H in the same manner as the rear ones to the hind axle; but no braces run from the couplings to the reaches, as in case of the rear attachments. The shackles depending from the middle line of the under side of the iron axle, all strain upon the reaches is prevented.

It will be observed that from the peculiar shape of the reach it serves at the same time as reach, brace, and axle-stock, giving unity, strength, and lightness to the whole structure.

The side springs are not represented, as they may be made, arranged, and hung to the shackles in any ordinary manner, their construction constituting no part of our present invention.

What we claim, and desire to secure by Letters Patent, is-

1. In a four-wheeled vehicle, the reaches The middle portion of the RR, bent as described, and united with the our own inv ention we affix our signatures in hind axle to form axle-stock, substantially in presence of two witnesses. the manner set forth.

2. The combination of the reach R, brace B, 5 strap 1), bearing E, and shackle C, all constructed and united in the manner and for the purposes specified.

In testimony that we claim the foregoing as Witnesses GEO. W. F. THOMPSON. FRANK A. HAYWARD.
