'i' IQECIEICADIOZN' :forrningpart .of Letters Patent 'NO. 276,500, dated April 24, 1883.

Application filed February 10, 1883. (No model.)

.1 a l wh it conc n Beak-now h a l mins anrS. o haveinvented certain uewan-d'use u ments in Road-Carts; and I do declare the following ytO be a full clean andexact description of the invention, such as will enable oth ers skilled in the art to which itappertains to make and usethe-sa-me, refenenoe heing had to the accompanying drawings, and toiletters or figures of referencemarked thereor-,whichform a part of this specification.

Figure 1 of the drawings is a vertical sectional view of my cart. Fig. 2 is a top view; and Figs. 3, 4, and 5 are detail views.

This invention has relation to road carts;

and it consists in the construction and novel arrangementof devices, as hereinafter set forth, and pointed out in the appended claims.

In' the accompanyingdrawings, the letter 8 designates the axle, and d the side bars connected thereto. The shafts e are formed with downwardly-curved rear en'ds,which are firmly mortised into said side bars, and are braced at thejoint by means ot'angle-irons b. Each side baris formed with a forward extension, t,which is connected by brace-rod a to the shaft 0, in front of its rear bend. The shafts are connected by a cross-bar, 0. a

The body B of the vehicle is supported by springs in front, connected to the cross-bar ot' the shafts or to the side bars, and in rear by springs land joint-braces j andlr, the upper ends of which are pivoted to shackles g, on which the body rests.

To the upper and rear end of the spring I is attached a block or bearing, 6, to which the a lower ends of the joint -rods j and 7c are connected, the former being pivoted to a shackle, h, on said block. The spring-blocks are connected by the tie-brace y. The brace-rodsj extend forward and upward obliquely from the bearing 2' to the shackle g, and bear the weight of the rear portion of the body, transferring it to the springs Zthrough the spring block or hearing i. Thestay-rod Iain rear of the bracerod j, isalso pivoted to the shackle g. The stay-rod is designed to work in connection with the brace-rod j and the front spring or connection,'0. Its office is to prevent the rear por- Improve q tion of the bodyfrom swinging downward in a -G A.REN E l-fiwm enzr, I dStates,-residen atB an,

also through an qpeningor slot in the upwardly-.bent,rearendof the spring-block l, or bear- ..ingattherearendtof the spring-block, and re ceivesa .pivot -bearing, a, and a nut, 9. By

tightening or loosening the nut .p-the rear ,of

the body can be raised or lowered to suit the height of the horseor the weightoftheburden. j

The spring 1 is connected at its lower end to a shackle, q, and clip r,wherebyit is attached to f This spring extends obliquely backthe axle. ward and upward, supporting tbe spring-block. At its rear end is formed a boxing or hearing, m, for the pivot piece a, through which the stay-rod passes. The fulcrum-pivot it permits a vibratory movementof the stay-rod, preventing it from being injured. The play of the stay-rod at its lower end is also necessary to secure the full benefit of the action of the spring I.

The front connection or spring, 0, may be made in elongated and curved form, and may be connected to the cross-bar c by means of a shackle and clip. In addition to its function in supporting the front of the body, it is designed to assist the stay-rod kin preventing the downward tendency of the rear of the body and the swinging of the rear springs in a radial manner around the axle.

The transverse equalizing-connection y is designed to resistside action of the springs, and holds them in position.

W'hen the forward springs are designed to be connected to the side bars they are made in edge-curved or horseshoe form, as indicated at 0, the spring having also a vertical curvature or upward arch from its outer end,which bears on or is connected to the side bar, to its inner end, which is connected to the sill ofthe body. Usually the outer and lower end of this spring is pivoted to a shackle which is clipped to the side bar. This spring is designed not only to have the ordinary upward elasticity, but also a torsional elasticity, which renders it of especial fitness for cooperating with the stay-rod rear end of the body while supporting its front end.

A horseshoe shaped torsion spring is not broadly claimed herein.

Having described this invention, what 'I claim, and desire to secure by Letters Patent,

1. The combination, with the axle and side bars, of the rear springs extending obliquely upward and backward, the spring-blocks connected thereto, and the pivoted brace-rods and adjustable stay-rods engaging bearings of the spring-block, substantially as specified. 2. The combination, with the axle and side bars, of the rear springs, extending obliquely backward and upward from the axle, the sprin gblocks, brace-rods, stay-rods, and front springs or connections, substantially as specified.

3. The combination, with the axle, shafts, and side bars having braced connections to said shafts, of the oblique rear springs, supporting bracerods and stay-rods extending to the rear portion of the body, the transverse equalizing connection 9 and the front springs or connections supporting the front of the body, substantially as specified.

4,. In a road-cart, the combination, with oblique rearwardly-extending rear springs, supporting pivoted brace-rods extending upward to the body, of the adjustable stay-rods in rear 0 of the brace-rods, and edge curved torsionsprings supporting the front portion of the body and connected to the side bars, substantially as specified.

5. The oblique rear spring having a shackle- 3 5 bearing at its lower front end and a box-bearing at its upper rear end for a fulcrum-piece on the stay-rod, substantially as specified.

6. The combination, with the rear spring, of the spring-block, the shacklesg and h, the piv- 4o oted brace-rod, the adjustable stay-rod having its lower end threaded, the pivot-piece through which the stay-rod passes, and the nut engaging its end, substantially as specified.

In testimony whereof I affix my signature in 5 presence of two witnesses.
