UNITED STATES WILLIAM E. CRANDALL, OF NEV YORK, N. Y.

ROCKING-HORSE.

SPECIFICATION forming part of Letters Patent No. 326,721, dated September 22, 1885.

Application filed January 24, 1885.

To all whom it may concern:

Be it known that I, WILLIAM E. CRAnDALL, a resident of New York city, in the county and State of New York, have invented an Improved Rocking-Horse, ofwhich the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which- Figurel is a side View, partly in section, of my improved rockinghorse. Fig. 2 is a crosssection of the same on the line x x,Fig.l. Fig. 3 is a longitudinal section on an enlarged scale of the parts that connect with the spring. Fig. 4 is an enlarged face View, and Fig. 5 an enlarged side view, of the spring holding clamps.

This invention relates to a new rockinghorse in which a coiled spring is placed directly beneath the center of the rocker to normally hold the horse in the middle posi tion, thereby greatly facilitating the use of the toy.

The invention consists in combining a rocking-horse or rocking toy with a coiled spring, which is placed directly beneath the center of the rocker-frame, and with certain holders for securing thereto the ends of the spring, as hereinafter more fully specified.

In the drawings, the letter A represents a suitable rocking-horse or other contrivance that is placed on rockers B B, which rest on the side rails a of a stationary frame, C. At the middle the two rockers B B are united by a cross-bar, D, beneath which is a crossbar, E, which unites the two rails a of t-he stationary frame C.

F is a coiled spring, which is interposed be tween the two cross-bars D and E and attached to them in manner hereinafter described, and which, when the parts are in the position shown by full lines in Fig. l, is in its normal condition-that is to say, the tension of the spring is such as to draw the cross-bar D and hold the same directly over the crossbar E. When the person on the rockinghorse leans the same forward or backward,as the case may be, the spring F is immediately distended, as indicated by dotted lines in Fig. 1, and being so distended tends to swing the (No model.)

horse back to its central position, theimpetus carrying the rockers over the central position, when the spring is again distended, serving thus to keep the rocker in motion. It will be seen, therefore, that by using the single central spring,when the same is so constructed that it will be distended whenever the horse is rocked, the labor of bringing the horse back to its central position will be almost wholly assumed by the spring and taken oif the rider.

In Figs. 3, 4, and 5 I have shown in detail the means of securing the ends of the spring F. For this purpose I employ two circular plates,b and d,one for the upper and the other for the lower end ofsaid spring. Each of these plates has on its outer periphery a spiral thread for receiving part ofthe coiled spring F. This spiral thread is clearly shown at e, in Fig. 5. The plate b is riveted to a plate, f, which in turn is riveted or bolted to the under side of the crossbar D, and the plate d is riveted to a plate, g, which in turn is bolted or otherwise fastened to the upper side of the crossbar E. By this connection the ends of the spring are securely held in place,and theplates b d, by engaging the terminal coils of the spring, hold the spring in proper tension, as they prevent it from contracting or expanding longitudinally.

In order to keep the rocker B in position on the frame C, said frame is on its outer sides provided with cheelcpieces h IL that iiank the sides of the rocker, as shown in Fig. 2, and assist also in preventing the single coiled spring from twisting out of shape.

I claim nothing that is shown in Letters Patent Nos. 214,871, 304205, and 222,398.

I claim- The combination of the coiled spring F with the spirally-threaded circular plate b, plate f, spirally-threaded circular plate d, plate g, and cross-bars D E, substantially as herein shown and described.

WILLIAM E. CRANDALL.
