UNITED STATES PATENT ()FFICEQ CHARLES CUMINGS, OF CINCINNATI, OHIO.

ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 394,836, dated December 18, 1888. Application filed September 3, 1888. Serial No. 284,486. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES CUMINGS, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and use ful Improvement in Road-Carts, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a side view of the cart equipped with my improved adjustable spring. Fig. 2

a top view of the same. Fig. 3 is an enlarged sectional view of the adjustable spring; and Fig. l, a perspective view of one of the side limbs of the frame, showing the application of the metallic re-euforcing strip on the side.

The object of my invention is to provide a road-cart with adjustable springs and to construct the frame in a rigid manner; and the novelty consists in the construction of the frame and seat and in the combination of the frame and seat with the spri n and shafts, all as will now be more fully set out and described.

It first consists of a frame and seat the forward end of which is hinged. to a forwardlyprojecting spring and the rear end suspended on a hanging adjustable spring, so that the height of the seat can be regulated and the weight of the occupant of the seat adjusted; secondly, the side pieces of the frame or bed are made of wood, re-cnforced on their inner sides with metal pieces, all of which willnow be set forth in detail.

In the accompanying d rawin gs,A represents the axle having suitable wheels. The rear ends of the shafts I3 have their rear downturned ends attached rigidly to this axle at points near the hubs of the wheels. Curved cross-bars C 0 on the upper side serve to hold the shafts in proper relative positions to each other. Centrally to these the singletree D is pivoted.

Heretofore in devices of this kind the'frame for the seat and dash has been usually made of long pieces of wood bent or curved in a pcculiar manner, and the elastic action of the seat has been obtained by means of springs between the frame and shafts at a point about midwaybetween the seat proper and the front This structure has largely on the frame and in the location of the springs.

Hy invention contemplates a very rigid frame, and that the elastic motion of the seat shall be caused by the peculiar hinging of the front end of the frame and the location of the springs with relation to the seat and shafts.

The frame or bed is composed of the side pieces, I, which are suitably mitered and framed together so as to form angles for the dash F, foot-board G, and seat H, as shown in Fig. 1. By the side of these limbs is a re-enforcing metallic strip, 1, made in one piece and securely bolted to and upon all the pieces E, composing the limb, as shown in detached Fig. 4. Each forward upturned end of the bed or frame is hinged to the forward end of a slightly and downwardly curved spring, J, the rear end of which spring is bolted to the under side of the shaft-piece 15. At a point slightly to the rear of the angle K, formed by the junction of the dash and foot board, is a hook, L, and directly above this hook, on the inner side of the shaft-piece B, is a similar hook, M. To these two hooks are attached the opposite ends of the peculiarly-constructed spring, which I will now describe.

The base is composed of a circular ring, N, having on opposite sides two exteriorly-proj ectin g ears, 0, provided with holes. The ring has on its'upper side an annular flange, P, and a ledge, Q, inside of the flange. The stirrup R has each of its limbs at the lower end screwthreaded and adapted to pass through the holes in the ears 0, nuts S being screwed thereon to hold the stirrup and ring together.

The spring T is conical in shape,- and so coiled that its base, which is the larger part,

.will fit within the annular flange I" and rest on the ledge Q.

U represents a rod having at its lower end an eye, V, and its upper end screw-threaded. The upper end of this rod passes through the upper reduced end of the coiled spring, and is held therein by means of a nut, \V. The upper end of this stirrup is attached to the hook on the shaft 13, while the eye V of the rod U is attached to the hook on the limb E of the bed. The rear end of the bed and the seat are therefore suspended on the spring T,

and the forward end of the bed is also capaits disadvantages in putting the strain so ble of a slight vertical movement through the medium of the spring I. In action, the user can adjust the rod up or down in the coiled s 'n-ing' by means of the nut \V, thereby enabling the seat to be thrown higher or lower, or to emnpensate for any additi mal weight which might be plaeed on the seat. The structure of this spring" is sueh that the least opportunity is offered for lode'ment of dirt, while the flanges are an elleetiuil proteeiion to hold the spring in place.

\Vhat I elaini as new is- 1. In a road-eart, the frame eonsisting of the side pieces, E, suitably mit ered and trained to form angles for the dash, toot-board, and

seat, and seeured to metal side strips, 1, each each side of the frame and slightlytothe rear of the angle K between the dash and footboard.

An adjustable springforroad-carts,coinposed of the base-rin provided with side ears and on its upper side an annular flange suspended on a stirrup, in combination with a eonieal eoiled spring mounted on said basering, its enlarged part Within the flange oi? the ring, and a vertical rod having an eye at its lower end and sermv-threaded at its upper end, and provided with an adjusting-nut, substantially as herein set forth.

In testimony that I claim the foregoing I. have hereunto set my hand, this 145th day of l ebruary, NR8, in the presence of \vitnesses.
