603.051. Rocking horses. SANDERS, E., HELLIWELL, E. G., and RANSOM, J. Nov. 17, 1945, No. 30914. [Classes 136 (i), 136 (ii) and 136 (iii)] [Also in Group XV] A rocking horse a is mounted upon a wheeled support by means of a transverse pivot rod b at the apex of a triangular frame c, the base member being supported by means of brackets on an axle d on which is mounted a pair of wheels e, the said mounting of the horse being such that rocking motion is transmitted from the body by means of pivotal links and j2 coupled at their outer ends to the body forwardly-and-rearwardly at h and at their inner ends to a one-way propellant mechanism at k<SP>2</SP>, the said mechanism being disposed substantially beneath the fixed pivot b and carried on the axle d, additional supporting wheels f and g being provided forwardly and rearwardly of the wheeled support, and the transmission of the rocking motion to the one-way propellant mechanism causing the base to traverse in a forward direction. In the form shown in Fig. 3, the one-way propellant mechanism comprises a gapped disc l keyed or bolted to the axle d and surrounded by two flanged half casings k and k<SP>1</SP> bearing integral lugs k<SP>2</SP> to which the links j and j are coupled. Located in the gaps l<SP>1</SP> are balls or rollers m which constitute anti-friction one-way coupling means between the inner sides of the flanged peripheries of the casings and the bases of the gaps, the said bases being inclined to provide a wedging effect. The disc l is almost as thick as the distance between the inner surfaces of the casings, but can nevertheless move freely within them, and two series of balls are provided, each series to operate with one casing, and being separated by a locating ring. On moving the head of the horse downward, the link j<SP>1</SP> will be pulled upward, this pull transmitting a rotational movement to the half casing k<SP>1</SP> to which it is attached. This in its turn transmits a forward traverse to its series of balls and causes disc l to rotate and with it the axle upon which it is fixed, and in consequence the horse and base proceed forward. A pawl and ratchet mechanism may be substituted for the mechanism shown. Steering means may also be incorporated.
