IMPROVEMENT IN SPRINGLREACHES FOR'VEHICLES.

Specification forming part of Lctt( rs Patent No. 153,334, dated July 21, 1874; application tiled March 16, 1874.

To all whom fit may concern:

Beit known that I, ELLwooD GRIMsHAw, a resident ot the city ot' Minneapolis, county ot' Hennepin and State ot' Minnesota, have invented certain new and useful Improvements in Carriage and Road Wagon Springs, of which the following is a-t'ull, clear, and exact description The object of my invention is to provide an economical spring for roadwagons which will have no longitudinal motion and it consists in attaching the ends ot' sections ot ordinary ellipticalsprings to bars of wood which pass from the head-block to the rear axle and avoid the ordinary reach, the springs and connecting-bars acting in that capacity.

Figure l shows my invention as attached to a road-wagon; Figs. 2, 3, and 4 being details of the spring'.

The same letters of reference are used in the various tgures in the designation of identical parts.

Letter A, Fig. 2, shows one half ot' an ellip# tic spring, A showing another halt'. Letters B B show two wooden connecting-bars, to the ends ot' which the springs A A are attached by the clips C C. The clips O secure the lower and rear end ot' the spring, as a '1 and 2.

whole,- to the hind axle I), the clips C securing` the lower and front end ofthe spring, as a whole, to the head-block D', as shown in Figs. In the use ofthe spring the lower elongating bar B is made to take the place ot' a reach,as shown in Fig. 1. The wagon-body is attached to the upper elongating bars B by the aid of clips E, or other suitable devices, as shown in Fig. 1.

I ain aware that the ends of C-springs have been attached to wooden bars to forni a carriage-spring and laid parallel to the axles; this I do not claim.

H aving thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl The bar B, having one arm of the springs A A fastened to its ends by clips O Gf, in combination with the bar B', having the other arms of the springs A A fastened to its ends, with one end resting on the rear axle and the other end on the head-block, all constructed to operate in the manner and for the purpose s et forth.
