SPRING-VEHECLE.

SPECIFICATION forming part of Letters Patent No. 331,334, dated December 1, 1885. Application filed August 26, 1885. Serial No. 175,389. (No model.)

To all whom it may concern.-

Be it known that I, OYRUs W. SALADEE, a citizen of the United States, residing at Shelton, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Vehicles, of which the following is a specification.

My invention relates to that class of vehicles in which longitudinal springs support the body; and my invention consists in constructing and connecting the springs, as fully set forth hereinafter, so as to secure an easy elastic support, prevent side motion and the turning of the axles, and generally improve the spring-platform.

In the drawings, Figure 1 is a perspective view of the running-gear of a buggy illustrating my invention. Fig. 2 is a perspective rear view of the front axle. Fig. 3 is a plan View of the gear with the body and wheels removed. Fig. 4 is a detached side elevation of the yoke to which the front ends of the perchsprings are connected. Fig. 5 is a side elevation of the wagon. Fig. 6 is a plan view of gear, showing a modification. Fig. 7 is a side elevation of one of the side springs, showing one form that may be used.

' In carrying out my invention I use the usual front axle, J, rear axle, K, front bolster, I, two parallel springs, a a, on the same horizontal plane, constituting together the central springreach, B, and longitudinal side springs,A,each of which may be single or duplex in character, the reach and side springs being all of the same length, and curved so as to operate properly in unison. The central portions of all the longitudinal springs are rigidly connected by cross-braces O G.

In the construction shown in Figs. 1 and 2 each side spring, A, is a single spring; but in that shown in Fig. 6 each side spring, A, consists of two similar springs, 12 b, on the same horizontal plane, and D D are clips secured to the ends of the bolster and rear axle, and each provided with an eye receiving a transverse bolt, E, that supports the ends of the adjacent springs 11 I), connecting them, but preserving them at their proper distance apart. When the duplex springs are used with a rigid frame-gear, their ends may be supported by links hung to the frame. The rear end of the duplex-spring perch is carried by a bolt, E, supported by a hanger, H, pendent from the rear axle, and integral therewith or secured thereto.

S, Fig. 4, represents a yoke, to which the front end of the duplex-spring perch is connected. The yoke has an eye, H, integral with the main body of the yoke, which latter is extended and bent up to connect with the rear side of the bolster at S. The front end of the yoke is supported in relation to the bolster by a bracket or hanger, IF, the upper end of which is attached to the bolster at 8*, and its lower end passes through the yoke. A king-bolt, V, passes down through the bolster and axle and the yoke,as seen in Fig. 4..

T represents the body, which is supported by cross bars or stays resting on the side springs.

By making the side and reach springs all of the same length, and so as to act in unison with like efi'ect, which latter result is best attained by making them all of the same curvature, I prevent the vibration of the springs from causing any rotation of the axles, and by connecting all the springs at the centers I stay the body against side or tipping motion when the load is on one side.

WVhen the front and rear parts of the frame are connected by a single spring, or two springs, one above the other, centrally arranged, the spring has no effect in tending to keep the other parts in their position at right angles to it; but when two springs are arranged side by side, each connected at each end to the frame and connected centrally together, the springs act effectively to stay and brace the front and rear parts and maintain them in their required positions without the use of the ordinary axlestays. The duplex-spring perch also insures great strength, a security against accident, should one of the pair be fractured, and, in combination with the side springs, insures a soft and easy motion to the body, as well as imparts to the complete structure a finished and elegant appearance.

hen duplex springs are used for both the perch and the side springs, as shown in Fig. 6, the lateral distribution of the steel admits of thinner plates than where single springs are employed in the usual way for both the side springs and center spring-perch, and hence a softer motion is secured, while the carrying capacity remains the same in both cases; and, besides, greater security against accident is assured, since each spring is duplicated, and the one spring of each pair is a support and brace to the other as well as to the entire structure. I

It will be understood that the arrangement of duplex side springs seen in Fig. 6 of the drawings may as well be applied to vehiclegears having a rigid perch or perches connecting the axles as in combination with the spring-perch shown in the drawings.

All the springs may be semi elliptical springs, as shown in Fig. 7, or they may be of any other suitable forms.

When duplex side springs are used, the body may extend over and be bolted to the inner spring of each pair only, as shown in dotted lines, Fig. 6, thereby permitting the side springs to be placed farther from the center, securing a wider spring-platform and better support. Moreover, as the weight is increased the inside spring closes up against the bottom of the body, and thereby becomes stiffer as it is distended.

Without limiting myself to the precise construction and arrangement of parts shown, I claim--.

1. In a roadwagon, two similar springs extended to connect the axles or bolsters, said springs being arranged longitudinally side by side on the same horizontal plane throughout their entire length, and having their opposite ends carried upon a single trunnion pin or bolt supported by the frame, substantially as described.

2. In a road-wagon, a spring-perch consisting of two similar flexion-springs arranged side by side, extended to connect the axles, and having their center portion rigidly secured in respect to the bottom of the body, substantially as described.

3. The combination, with the perch consisting of similar springs arranged side by side, of side springs and central connections between the side springs and the springs of the perch, substantially as described.

4. The combination, with a duplex-spring perch consisting of two similar parallel springs side by side, of the upper side springs, A A, and. transverse connections, substantially as described. 5. The combination, with the rear axle, the suspended arm H, and rear springs, a a, of the duplex-spring perch B, substantially as described.

6. The yoke S, connected to the front bolster and interposed between the parallel springs a a, composing the spring-perch, substantially as described.

7. The eyes D D, interposed between the duplex side springs, b b, substantially as described.

8. The combination of the frame, side springs consisting each of a pair of springs arranged side by side, and a body extending over and secured above the inner spring of each pair, the outer springs being beyond the body, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
