VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 349,541, dated September 21, 1886.

Application filed January 4, 1886.

To all whom it may concern.-

' Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Springs, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a front view of a pair of my improved buggy-springs. Fig. 2 is a plan view of the same, and Fig. 3 a perspective view of one of the springs detached.

In an ordinary buggy-spring as attached to side bars it is usually necessary to provide the main part of the spring with superimposed leaves in order to make it ofsufficient strength. This feature of course makes the spring very flexible.

My invention is designed to obviate this difficulty, inasmuch as I form it of a single bar of steel, the inner part of which is bent so as to form a loop, which makes it flexible, and answers all the purposes of the superimposed leaves, as in the old method, all of which will now be fully set forth.

In the accompanying drawings, A represents the cross-section of an ordinary buggybed, and B the transverse bar beneath. Attached to this bar I provide laterally-disposed Springs 0, each one of which is formed of a single bar of steel, and with usual loop-andstirrup connections, D, at their outer ends. Inwardly the ends of these pieces adjoin each other, and are bolted in position securely, as shown at E, to the said transverse bar B. Oct wardly from'these bolt-connections E, and on a horizontal line between them and the connections D, each of the bars or springs O is provided with a loop, F, therein. These loops F, as the spring operates, expand and contract,

and give the necessary flexibility to the spring.

As will be obvious, the construction of this spring is a great deal more simple than usual, and does not require any special machinery in order to construct it, and in addition the spring, when formed in this manner, can be made very much lighter than ordinarily, and at the same time still have the necessary strength. I design this form of spring to be used. with the ordinary side-bar connections; but, as will be obvious, it can be adopted in other cases, as desired.

I am aware that heretofore a vehicle-spring has been made of a. single rod with a perpendicular coil formed near its center, the projecting ends of said bar extending in the same direction, and one end fastened to the body of the carriage and the other to the side bar; also, that a spring having a loop has been placed lengthwise under the carriagebody, attached to the axle at one end and under the footboard at the other.

Having described my invention,what I claim JOSEPH VO-NDRISKA.
