IMPROVEMENT IN CARRIAGE-SPRING.

TO ALL WHOM IT MAY CONGERNz Be it known that I, JOSIAH R. LOCKE, of the city and-county of San Francisco, State of California, have invented an Improved Carriage-Spring; and I do hereby declare the following description and accompanying drawings are suflicient to enable any person skilled in the art or'science to which it most nearly appertains to make and use my said invention or improvementwithout further invention or experiment.

My invention consists in providing a light, easy, and durable spring for carriages or buggies. The spring is constructed partly of wood and partly of metal, so arranged and applied as to impart to it the greatest elasticity without impairing fits usefulness. There are two springs at each side of the wagon, attached to the bottom of the bolster at one end, and the axle-bed at the other, around which they pass in a graceful curve to the side rail of the carriage, where they separate in opposite directions by a goose-neck curve, in which position they are bolted to the side rail. Back of each of these springs is placed a small double-acting spring,'the upper portion being attached to the rail, and the lower working in a slide.

To more fully explainmy invention, reference is had to the accompanying drawings, forming a part of this specification, which shows a side view of the springs and their attachment to the frame on one side of the bugg A A represent the front and back springs, extending from the lower ends of.the reach, passing around the bolster and axle-bed to the raii or bed B of the buggy, to which they are bolted, forminggoose-neck curves D D, in opposite directions. The outer portion of the spring is steel, a, and passes around'the wood spring a, near the upper or thick end, 6, at which point the wood portion is gradually curved to a thin edge. The gooseneck springs are also constructed ofsteel, and pass down a considerable distance below the top steel spring, so that the wood spring is held between the two steel springs t9 furnish strength at the needed points. i

The wood in the curves or cs are shaved thin, so that in connection with the steel plate around it, sufficient strength and elasticity are had.-

Near the thick part of the springs A are attached slides E E, in which the double-acting springs F F work, the lower endacting on the upper steel face of the spring a, and entering the slide band. The opposite end is curved, and extends down to near the face of the spring, below the slide, so that when the buggy is heavily loaded, these curved ends will gently strike upon thesprings beneath, and the springs, one acting against another, produce the'efl'ect of a coil-spring,-which will carry double the load of the common elliptic spring of the same weight, and not affect the reaches of the wagon.

Figure 2 shows, in red, a device which'may be employed to prevent the wagon from spreading laterally.

By this combination and arrangement of springs, a wagon of great case is bad, and very simple in construction.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is 4 1. In combination with the wood and steel springs A A, the goose-neck springs D D, constructed substan- I tially as described.

2. The double-acting springs F F and the slides Edit, in which the lower ends move, or equivalent device, the whole constructed to operate substantially as described.

In witness whereof, I have hereunto set my hand and seal.
