ISAAC A. WESSON, OF WINGO, KENTUCKY.

SULKY-SPRING.

SPECIFICATION formingpart of Letters Patent No. 275,445, dated April 10, 1883.

Application filed August 19, 1882.

To all whom it may concern:

Be it known that I, ISAAC A. WESSON, of Wingo, in the county of Graves and State of Kentucky, have invented certain new and useful Improvements in Sulky-Springs; and I do hereby 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 7 it pertains to make and use the same.

My invention relates to improvements in sulky-springs, the object of the same being to combine the seat and springs with the shafts in such amauner that the driver will not be subjected to the sudden jars usually experienced'while riding in sulkies of ordinary construction; and with these ends in view my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

The accompanying drawing represents my invention in side elevation with one wheel removed.

A represents the ordinary shafts of the sulky; B, the sulky-body, and 0 two longitudinal cleats secured to the said body on opposite sides thereof.

D are four curved springs, arranged in pairs on opposite sides of the body, and rigidly secured at their lower ends to the cleats 0. These springs can be any convenient height, and each is provided at its upper ends with a loose ring, E, through which the seat-supporting straps F pass.

G is the drivers seat, provided on its under surface, near its opposite sides, with the semi-elliptic springs G. These springs are centrally secured to the bottom of the seat, with their concavity downward, and each one is also provided on opposite ends with the rings E, through which the Seat-supporting straps F also pass. The springs D, on the same side of the sulky, are separated for a distance nearly equalto the length of the semi-elliptic spring G, on the same side thereof, so that the supporting-straps F will hang in nearly a vertical position. These supporting-straps (four in number) are made of leather or other suitable flexible material, and are provided at suitable intervals apart with perforations, through which are inserted keys afor the purpose of holding the parts together. The straps are first passed throughtheir re- (No model.)

spective rings, as shown, and then both ends of each strap are passed through the ring E. The seat is then vertically adjusted to suit the driver, and the keys at then passed through the perforations in the straps below the rings E, and form stops, on which the seat rests. The free ends of the four straps are then secured to the cleats (J by the same bolts which secure the springs D to the said cleats, or in any other suitable manner, the straps F being sufficiently slack, however, to enable the seat to move laterally and longitudinally when the wheel or wheels come in contact with obstructions or when riding over uneven ground. By securing the lower ends of the straps to the sulky-body the swinging or vibratory motion of the seat is limited. The straps F, besides performing the function of limiting the movement of the seat, also form a flexible connec tion betweenthe verticaland horizontalsprin gs, and admirably adapt the improvement for use on rough roads.

It is evident that slight changes in the construction and relative arrangement of the dil ferent parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do notlimitmys'elfto the exact construction shown and described, but consider myself at liberty to make such changes and alterations as come within the spirit and scope of my invention.

Having fully described my invention, what I claini as new, and desire to secure by Letters Patent, is-- 1. In' a vehicle, the combination, with the body, seat, and springs D and G, of the rings E and E, flexible straps l and means for adjusting the straps to raise or lower the seat, substantially as set forth.

2. The combination, with the body, seat, and springsD G, of the rings E E and flexible straps F,secured" to said rings, and at their lower ends secured to the body, substantially as set forth.

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

ISAAC A. WESSON.
