IMPROVEMENT IN VEHICLE-SPRINGS.

Specification formingpart of Letters Patent No, 150,685, dated May 12, 1874; application filed February 7, 1874.

To all whom it may concern:

7 Be it known that I, JAGOB H. GOULD, of Rutland, in the county of Meigs and State of Ohio, have invented a new and Improved Oarriage-Spring, of which the following is a specification In. the accompanying drawing, Figure 1 represents a sectional end view of my improved carriages1')ring; and Fig. 2, a horizontal longitudinal section of the same on the line 0 c, Fig. 1. r

Similar letters of reference indicate corresponding parts.

The object of my invention is to produce a spring for vehicles of all kinds which gives great resistance and uniform elasticity to the weight pressing thereon, with less material.

'andfriction, being also less expensive in its manufacture, and, 011 account of the equalized strain, more durable and satisfactory. My invention consists of a series of spring plates or leaves, which are tapering from the center toward the ends, and of equal thickness along The leaves A are made of steel plates, of equal length and thickness throughout, either of symmetrical halves, or extending the full length from socket to socket. They are tapering in width from the central part to the end, and flat, without corrugations, to produce an equal degree of elasticity throughout their full length, and prevent thereby breakage caused by unequal strain on any part thereof. Each leaf A is attached, separately from the other, to the central blocks B and sockets, and at such distance apart that they do not come in contact with each other, however great the pressure exerted on them.

In case half leaves or plates are used, the central blocks B are recessed at the ends, for

taking up the sam e, and bound firmly together by vertical cross-bolts a.

If full plates are used, separate blocks are interposed between, for retaining the requlred distance of the plates.

The outer ends of the leaves A rest on sep arate pins 1), which are lubricated by an oiled wick, or similar substance, placed vertically in the sockets back of the pins, as shown 111 Fig. 1. The friction of the springs and wearin g out of those parts are thereby materially reduced.

For the purpose of adjusting the springpower to the weight to be supported, the intermediate or middle plates may be made detachable, and inserted or taken out, as required. The inner ends are, therefore, provided with slots (1, as shown in Fig. 2, wh ch slide onto the connecting-bolts a, resting with the outer ends loosely upon their socket-pins.

Repairs can easily be made, as any injured plate may be replaced without dispensing with the rest.

The action of the spring is uniform throughout its full length, producing thereby more agreeable movements and greater com-fort to the occupant of the vehicle.

Having thus described my invention, I clann as new and desire to secure by Letters Patent' l. The vehicle-spring composed of separate tapering leaves A, central blocks B, and lubrieating-sockets O, all combined in such manner that the plates are constantly retained at certain distance from each other, as and for the purpose described;

- 2. The detachable spring-plates A, with side slot d, in combination with the cross-bolts a, supporting-blocks B, and the lubricated socket-pins, as and for the purpose described.
