ROAD-CART."

S PECIFICATION forming part of Letters Patent No. 416,241, dated December 3, 1889.

v Application filed September 28, 1889. Serial No. 325,440. (No model.)

To all whom it may concern.-

Be it known that LROBEET D. SCOTT, a citizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Road-Carts; and I declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to .make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention is designed to produce a roadcart in which the body is so supported that it may be adjusted to a higher or lower level, as desired; and it consists, essentially, in the provision of a series of hooks on the rear end of the shaft over which the hangers or clevises on the ends of the semi-elliptic spring are engaged. These hooks are arranged one underneath the other, but each one is beyond the vertical line of the one next below it.

My invention also consists in other novel features of construction hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of a shaft illustrating my invention. Fig. 2 is a view at right angles to Fig. 1. Fig. 3 is a rear elevation of a portion of a shaft, illustrating a variation of my invention. Fig. 4. shows a rear elevation of a portion of my cart, illustrating how the ends of the semi-elliptic spring are connected with the hooks.

In carrying out my invent-ion, A represents the shafts, B the axle, and C the semi-elliptic spring for supporting the body. This semielliptic spring is attached about its middle to the body by means of the support D and, bolts d.

of the semi-elliptic spring by the bolt g.

His a suitable link, one end engaged to the clevis, the other end engaging over the hook. Vhen the hooks are placed on the shafts, as shown in Figs. 2, 3, and at, one end of the link H must be turned at right angles to the opposite end, so that the link can properly en gage over the hooks.

It will be observed that the hook F is outside or beyond the vertical line of the hook F and that the hook F is outside or beyond the vertical line of the hook F. By thus arranging the hooks one beyond the other any interference of the link with the hook next below the one in which it is engaged is prevented, and a free and unimpeded action is insured, no matter in which one of the hooks the link is engaged. This I regard as a very material improvement, since, when the hooks are placed one beneath the other in the same vertical line, the link or loop, when engaged over the upper or top hook, would, when the cart is in motion and the body swinging more or less, strike the hook next below the one with which it. is engaged and thus prevent free act-ion.

It is of course immaterial whether the hooks be turned inward toward the shaft, as shown in Figs. 2 and 4, or whether they are turned outward, as shown in Fig. 3; but I prefer the former construction, since should the link or loop become disengaged with a hook it is caught by one of the lower hooks before it allows the body to drop entirely down. By thus supporting the semi-elliptic spring, and consequently the body, by a series of hooks, and arranging each hook successively beyond the vertical line of the one next below it, any friction or interference is prevented and a much freer action is obtained than has heretofore been accomplished. So, also, by forming the hooks in a single piece and causing them to project in at right angles from the shaft the semi-elliptic spring, when engaged to the hooks, has a free swinging motion from front to rear-a result which could not be obtained if the hooks were directly underneath the shafts.

\Vhat I claim is 1. In a road-cart, the combination, with the shafts and a semi-elliptic spring for supporting the body, of a series of hooks attached to said shafts and located Outside of a vertical line through the shafts, each successive hook projecting beyond the vertical line of theme next below it, substantially as described.

2. The combination, with the shafts and a semi-elliptic spring for supporting the body,

of a series of hooks attached to said shafts and located outside of a vertical line through I the shafts, said hooks opening toward said shafts, and each successive hook projecting beyond the vertical line of the hook next below it, substantially as described.

In a road-cart, the eombinatiomwith the shafts and a semi-elliptic spring for supporting the body, of a series of hooks attached to 10 said shafts and located outside of a Vertical line through the shafts, said hooks formed in a single casting and each successj ve hook projecting beyond the vertical line of the hook next below it, substantially as described.

In testimony whereof I sign this specifiea- I5 tion in the presence of two witnesses.
