CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 289,078, dated November 27, 1883. Application filed August 29, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, Janus J. Fnrznn, of the village of Oolumbiana, in the county of Columbiana and State of Ohio, have invented a new and useful Improvement in Springs for Garriages; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My improvement relates to that class of carriages known to the trade as side bars, and it consists in the peculiar construct-ion of the to the side bars and body of the carriage, whereby a free, easy, and elastic motion is obtained for the body of the carriage, and said side bars having a vertical springing motion without undue twisting and straining action, all of which will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearlyconnected to make and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure 1 is a perspective view of a carriage (known as side bar) furnished with my improvement in springs. Fig. 2 is a top view of the springs and side bars detached from the running-gear and body of the carriage. Fig. 3 is a side view of the spring. Fig. 4 is a top view of the coupling for attaching the spring or springs A to the side bars. Fig. 5 is a side view of the same. Fig. 6 is a transverse section of the same at line y y of Fig. 5. Fig. 7 is a top viewof the coupling for the springs B. Fig. 8 is a side view of the same. Fig. 9 is a transverse section of the same at line as a: of Fig. 8.

In the construction of side-bar carriages the front and rear springs are attached at their ends rigidly to the ends of the side bars. This causes thebody of the carriage to have a short jerking vertical motion. This rigid attachment of the ends of the front and rear springs destroys much of the elasticity of said springs, and causes an undue straining and twisting of the side bars, and at the same time partially destroys the elasticity of the spring or springs interposed between the front and rear springs. By constructing the springs and attaching them to the side bars as hereinafter described,

the foregoing objections will be entirely overcome, and a more easy and elastic action obtained for the carriage.

The springs A and B may be constructed with any desired curve; but the ends of said springs should be substantially of the form common to the upper half of the ordinary elliptic springs for carriages, which ends of the springs are pivoted to the couplings O and D by means of pins e, and said couplings attached to the side bars, f, by means of clips, as shown in Fig. 1 of the accompanyingdrawings.

It will be observed by reference to Fig. 1 that the springs A and B form an elliptic spring, with the side bars interposed between them, thereby securing all theelasticity common to the elliptic spring, with the additional elasticity due to their combination with the side bars, f.

The form of the couplings and their construction are clearly shown in the accompanying drawings, and need not be further de scribed, excepting their relations to the springs A B, the couplings 0 being for the springs A, and the couplings D being for the front and rear springs, B.

By the combination of the springs, couplings, and side bars hereinbefore described, the side bars are prevented from turning inward toward the body of the carriage by ends 9 of the springs A acting against the part it of the coupling 0, and the side bars are prevented from turning outward from the body of the carriage by the endsi of the springs B acting against the part 3' of the coupling D.

Having thus described my improvement, what I claim as of my invention is- 1. The combination of the springs A B, provided with stops 9 1", and couplings C D, having stops h j, arranged and operating substantially as herein described, and for the purpose set forth.

2. The combination of the springs A B, pro- ,vided with stops 9 z, couplings G D, having stops h j, and side bars, f, arranged and operating substantially as hereinbefore described, and for the purpose set forth.
