VEHICLE-SPRENG.

SPECIFICATION forming part of Letters Patent No. 306,770, dated October 21, 1884.

Application filed June 2, 188-1.

To all whom it may concern.-

Be it known that I, LEVI PENTZ, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Vehicle-Springs; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which- Figure 1 shows the general construction and arrangement of my invention. Fig. 2 is an under side view. Fig. 3 is a side view. Fig. at is a side view showing the position of the different parts when sprung. Fig. 5 is a detached view of a different form of lever. Fig. 6 is a detached view of a different form of jack or bearing for levers.

This invention has relation to that class of vehicle-springs known as side-bar springs; and the objects thereof are to construct the springs and connect them to the side bars of the vehicle in such a manner that the friction is greatly reduced, and the springs allowed to operate without strain on the bars, and at the same time will have an elliptic motion.

To such ends the invention consists in the combination of devices hereinafter described and claimed.

In the accompanying drawings, A represents the springs, which are substantially of the form shown in the drawings, and may be composed of any desired number of leaves, the leaves being held together bythe c1amping-bolt a. Two or more bolts may be used, if desired. Said bolt or bolts a pass through the cross bars or frames, as shown in Fig. 3. The springs A are rigidly held to the cross bars or fllln(S B by means of the clips b,which embrace the springs at their outer ends and a portion of the cross bars or frames. A metallic plate, 0, is provided for the purpose of protecting the cross bars or frames B. The springs A are formed so that their inner ends will come a short distance below the cross bars or frames, as seen Figs. 1 and 2.

To the inner ends of the springs A are at tached the levers D, by means of the arms d,

(No model.)

and are attached so as to form a hinge or To the bottom or under side of the cross bars or frames B are attached the cushions F, which may be made of rubber or any other suitable elastic material, and are for the purpose of preventing the levers D from striking violently against the cross bars or frames B.

The outer ends of the levers D are attached to the side bars of the vehicle by means of suit-- able clips in the ordinary manner.

It will be seen that by attaching the springs A as shown in the drawings I am enabled to produce a spring that will have what is known as an ellipticmotion, and at the same time am enabled to provide a spring which will be strong and well adapted for the purpose designed. It will also be seen that byattaching the levers D to the cross bars or frames B, as shown in Fig. 2, I am enabled to provide a compound leverage for the movements of the springs proper.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is I The combination of the cross bar or frame 13, the springs A, secured at one end thereto, the lever D, hinged at one end to the free ends of springs A, and extended toward the opposite ends of said springs, and secured at a point intermediate of its ends to said cross bar or frame, and the cushions F, interposed between the cross bar or frame and the levers, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

LEVI IENTZ.

In presence of ROBERT D. KUIIN, E. S. Earns.
