VEHICLE-SPRING.

SPECIFICATION formingpart'of Letters Patent No. 226,536, dated April 13, 1880. Application filed March 9, 1880. (No model.)

To all whom it may concern Be it known that I, OHAUNOEY M. MURCH, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a specification.

The object of this invention is to enhance the utility of the pyriform spring described in Letters Patent N 0. M9,? 77, granted to me April 14, 1874; and the first part of. the present improvements consists in constructing said spring in such a manner as to increase its elasticity and render it more secure and durable in action, as hereinafter more fully described.

The second part of my invention consists in prolonging the pyriform spring beyond the vehicle-axle, so as to afford means for a draft attachment, as hereinafter more fully described.

The third part of my invention comprises a novel method of securing the spring to the axle, as hereinafter more fully described. 4

In the annexed drawings, Figure 1 is aperspective view of the more simple form of my spring. Fig. 2 is a side elevation of the curved portion of a more complex form of the same. Fig. 3 is a vertical section, showing the preferred method of suspending a vehicle from said spring; and Fig. 4 is a vertical section of the spring at its junction with the axle of the vehicle.

Referring to Fig. 1, it will" be seen that the more simple form of my improved spring consists, essentially, of a continuous bladeor strip or plate, A B O, of steel or other suitable elastic material, of which spring the single leaf or prolongation A has an eye, a, to receive a bar or rail, D, that may be rigidly attached to the body of the vehicle in any preferred manner, said eye a being bent either up or down, as may be most convenient.

The two leaves B O are in close contact with each other at or near their junction with the axle E, and then gradually separate as they curve around to the point F, at which point they begin to approach each other, and are finally brought in contact where the eye f is formed. By this arrangement a crescentshaped opening, G, is afforded between these two leaves 13 and G, as seen in Fig. 2.

The extremity of leaf 0 is increased in thickness, so as to form a butt, H, having a shoulder, I, against which latter bears the cross-bar j of a clip or coupling, J, whose other bar, j, fits snugly against the extreme end of said butt, as more clearly seen in Fig. 4. It will thus be seen that this clip not only serves to unite the spring to the axle, but it effectually prevents the upper leaf, 0, sliding along the lower one, B. The spring may be still more securely attached to said axle by passing a rivet, K, through the butt H and leaf B.

The eye f may have engaged with it a stirrup, L, carrying a transverse bar or rail, M, upon which latter and the bar D the body of the vehicle may be suspended; but the preferred method of hanging the vehicle to the leaves of the spring is shown in Fig.3. In this illustration an angle-iron, N, is represented as secured against the under side of the vehicle-floor, and then inclinesupwardly and outwardly, and has at top an eye, n, through which and the other eye, f, is passed a pivot-bolt, O. This eye a servesto join the angle-iron N to a brace, P, which brace slopes down and is secured to the-upper side of the floor by the samecliplt that holds the angleiron N in position. An additionalb'race, S, may be employed, having one of its ends secured to a seat of the vehicle, while its other end maybe attachedito the side of the wagon or omnibus.

In the more complex form of the spring, shown in Fig. 2, extra leaves T are employed for sustaining the leaf B, and for carryingvery heavy loads both. of the curved members B C may have two or more supplementalblades fitted close to them, as seen inFigs. 3 and 4 of my old patent. Finally, the spring, whether constructed as shown in Fig. '1 or in Fig. 2, may be placed either above the axle E or below it, according to the requirements of the case.

In my old patent, previously alluded to, the spring acts simply as a suspension device, and has no provision whatever for receiving draft; but in the present instancethe prolongation or single leaf A performs this function, and as said leaf can be made very elastic, it isapparout that a vehicle supported on my new form of spring will have an unusually easy and yielding motion and will be free from any violent lateral jerks or surgin gs.

In addition to the above advantages, this device saves the weight and cost of two heavy transverse springs as ordinarily employed, it being understood that my present spring is designed to be placed on wagons, carriages, omnibuses, cabs, or any other vehicle where it can be advantageously used.

I claim as my invention- 1. The pyriform or loop spring B O G, havin g a draft prolongation, A, and two eyes, a f, the end of the leaf 0 being secured to the leaf B at or near the junction of the latter with the axle of the vehicle, as herein described.

2. The combination of leaves B O, axle E,

butt H, and rivet or bolt K, for the purpose explained.

3. In combination with leaves B O and axle 20 E, the shouldered butt H I and clip J j j, for the purpose herein described.

4. The combination of spring A a B O G f and leaves T, for the object stated.

5. The combination of leaves B O, axlevE, 25 shouldered butt I1 I, clip J j j, and rivet or bolt K, as herein described, and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
