SIDE-SPRING VEHlCLE.

SPECIFICATION forming part of Letters Patent No. 274,390, dated March 20, 1883.

Application filed June l5, 188:2. (No model.)

To all whom it may concern:

Be it known "that I, CYBUS NV. SALADEE, a citizen ofthe United States, and a resident of Torrington, in the county ot' Litcheld and State of Connecticut, have invented certain new and useful Improvements in Vehicles, of which the following is a specification.,

Mynvention consists inanew and improved mode ofconstructing and applying side springs to vehicles, as hereinafter fully described, and has for its object to admit of the vertical movement of the body without tilting, while carrying the body at 4a point directly below the cross-center of the seat.

In the drawings, Figure 1 is aside elevation of so much of a buggy as is necessary to show my invention applied.

3 is a diagram to illustrate the main points of improvement secured by my invention.

By reference to Fig. 3 it will be seen that the vertical line Ncoincides with the center of the body midway between the axles, and with the central point of attachment of the spring, and that line O coincides with the center ofthe seat. As the weight carried in these vehicles is on the seat, the line O will indicate to what extent the load must be back oi' the point of attaching the spring to the body, and shows that the spring does not support the body at that pointwhere the greatest part ot` the load is carried, and hence the liability (so common in this class of wagons) of the rear end of the body to bang or sag lower than the front end when loaded and in motion. l overcome this defect by giving to the rear halt of the spring substantially the form seen in Fig. 1, whereby to project the spring farther to the rear, and support the rear half of the body directly under the seat on the line O. The side spring is made ot' two sections, as shown, or-in one piece, and by extending the spring back of the axle and turning it to its point of suspension to the rear of the axle length is secured to insure a safe and easy spring-support. tion, l), of the spring cannot be of the same formas theu rear section, as in that case' it would be struck by the front axle as the lat- Fig. 2 is a plan viewv 'of the bottom ot' the body and gear, and Fi g.

The front sec- I ter is turned in turning the vehicle. This secf tion therefore must be of substantially the form ot' a true semi-elliptic spring. It' this latter form were duplicated for the rear half of the spring, it `would necessitate the use ot a link to' admit of the elongation of the spring under pressure; but in the, construction shown the curved end of the rear half, C, ot the spring permits the elongation of the spring and a free and easy vertical movement of the body. The front ends of the springs are jointed to irnmovable shackles on the `front bar, and the rear ends to immovable' pivots at the rear of the rear axle, thus permitting vertical motion of the body, but'no tilting thereof.

I propose sometimes to use the rear sec tions, C, Fig. 1, but with a cross-spring, D'. (Shown in dotted lines.) Said cross-spring may be of any suitable character, and applied to the side bars and bodyin the usual way. These springs are equally weil adapted to either the 'ordinary side-spring or to the side-bar77 gears now in general use, and 1 intend to use them in both classes of wagons.

I claim- 1. The combination, in a vehicle, of a body, frame,and side springs havingagreater length between their points of suspension than the distance between the bolster and axle, and connected to the body to support the same at a point nearest the rear end, with the front ends pivoted to stationary shackles and rear ends pivoted at therear of the rear axle, substantially as set forth.

2. A vehicle having side sprin gs, each in two l sections, the front sections bent to substantially true semi-elliptical form and pivoted to to this specification in the presence of two 9o OOURTNEY A. COOPER, A. E. T. HANSMANN.
