BENJAMIN S. PORTER AND CLARENCE W. PORTER, OF RED OAK, IOWA.

TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 375,381, dated December 27, 1887.

' Application filed May 11, 1887.

To all whom it may concern:

Be it known that we, BENJAMIN S. PORTER and CLARENCE W. PORTER, citizens of the United States, residing at Red Oak, in the county of Montgomery and State of Iowa, have invented certain new and useful Improvements in Road-Carts; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention and is a bottom View. Fig. 2 is a vertical section. Fig. 3 is a detail and a perspective view of the spring.

This invention has relation to two-wheel vehicles; and it consists in the construction and novel combination of parts, as hereinafter set forth.

In the accompanying drawings, the letter A designates the shaft-bars, and B the seat-bars connected to the shaft'barsin front of the seat, as indicated at O. The shaft-bars are properly braced across by a bar or bars, D, and by the axle to which they are connected. The seat-bars are of less width near the seat than the shaft-bars and are provided with eyes or bearings E.

I F indicates a pair of torsion-springs of obtuse angular form adapted to support the seat from the shafts, one on each side. The main length and horizontal portion of each spring F (indicated at G) is seated in clips or bearings H, which serve to secure the springs to the shaft-bar and also allow it torsional mo- Serial No. 237,870. (No model.)

tion. I In front of the forward bearing H the front end of the spring is set transversely in the form of a short arm, I, which engages the shaft-bar and acts in opposition to the movement of rotation which the spring would other wise have in the bearings H, so that torsional elasticity is secured. The rear arm, K, of each spring extends upward and rearward obliquely from the horizontal portion G, forming an ob tuse angle therewith, as indicated, and at its extremity this arm is set rearwardly, as at L, to enter the eye or bearing E of the seat-bar and engage the same, playing back and forth therein as the seat vibrates down or up under the weight imposed when the vehicle is in motion.

Having described this invention, what we claim, and desire to secure by Letters Patent, 1s-

1. The combination,with the shaft-bars and seat bars connected thereto, of the obtuseangled torsion-springs F F, having their horizontal portions connected to the shaft-bars by bearings, the forward ends engaging the shaftbars and the rear ends set rearwardly and engaging bearings of the seat-bar, substantially as specified.

2. The side torsional springs, F, having the short terminal transverse arm and the oblique arm K, forming an obtuse angle with the horizontal portion G, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
