, IMPlRVEMEN'i IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 173,834, dated February 22, 1876; application led January 4, 1876. i

4 To all whom tmay concern Be it known that I, HARRY K. WATER- HOUSE, of San Francisco city and county, State of California, have provements in Carriage-Springs; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

My invention relates to that class of carriage springs which have devices for equalizing t-heir action 5 and it consists of a combination of semi-elliptic springs with C-springs and a crank-rod connection, as hereinafter more fully described.

My improvements are fully described in the following specification, and represented in the accompanying drawings, in which- Figure l is a perspective view of my carriage.

Let A represent the front and B the rear bolster of a buggy or other vehicle, and C U the reaches which connect them. D D are C- springs, which I secure "in the usual way at the ends of the bolsters. The pair of C-springs at each end of the buggy or carriage I connect by a strong rod or bar, E, which has a crank, f, formed at each end. The ends of the rods outside of the cranks are secured loosely on the ends ofthe C-springs by coiling the springs around them, or by other equivalent means, by which the ends of the rods are journaled in the ends of the springs. A nut, g, is then screwed tn the ends ot' the rods outside of the spring, thus giving the rod also the character of a brace to prevent the Csprings from spreading. F F are the semie1liptic si 'e-sprin gs, whicliare secured at theirmiddles to the middle of the body G. The ends of these side-springs are secured loosely to the rods E E at each end of the buggy or carriage, inside of the cranks f, so that the rods can turn in the ends `of the springs. It will thus be seen that the body Gr is suspended from the crank-rods E, and will have a longitudinal motion equal to the throw of the cranks, and that the sidesprings can lengthen when depressed, without being cramped by rigid fastenings at the ends.

The combination ot' the side and C-springs gives an easy vertical action, while the motion of the crank-rods will relieve the stiffness or rigidity of that motion and give an easy swing to the body. The side-springs could be attached in the same manner to rigid standards or jacks so as to produce the same effect, instead of connecting them with C-springs. This arrangement also connects the action of the side-springs so as to producean equalizing effect, as the extending of one of the side-springs by a Weight placed upon one side ofthe buggy-body will cause `the erank-rods to swing outward and thus depress-the opposite spring, thus obviating the disagreeable e'ect of tipping the body to theside which supports the greatest weight.

Having thus describedmy invention or improvement, what I claim, and desire to secure by Letters Patent, is-

In a compensating vehicle-spring device the i semi-elliptic side-springs F F and crank-rods E E in combination with C-springs D D, as set forth.
