6 Claims. 1

This invention relates to toy horses whichmay be ridden by a child and has for its object to provide a toy of this kind which will be propelled by motions of the body of the rider in simulation of riding a live horse.

An object of this invention is to provide a toy mounted on Wheels and having a crankshaft with at least one crank throw for rotation of the wheels, the connecting rods for said crankshaft being so arranged that when the rider imposes his weight on the crankshaft through his feet the wheels will be rotated through approximately 180 and when he imposes his weight on the crankshaft by seating himself the wheels will be rotated through a second 180 thereby rotat ing the crankshaft to the starting position. In other words, the rear end of the body is pivotally attached to the crank of the crankshaft so that it rises and falls with rotation of the crank and consequently may be used to drive the crank through half a rotation. A shifting of the weight of the rider from the body to a linkage connected 5 to the crank, by alternately seating himself onthe body and standing in footrests simulating stirrups on the linkage, thus causes rotation of the crank through successive half revolutions and, therefore, through continuous revolutions.

Alternate shifting of the weight of the rider fromnected to foot rests and the other two being jour nalled jointly in thebody of the horse and in rear wheels supporting and propelling the body.

Another object is to provide a crankshaft connecting the rear wheels and having a single crank throw, this single: throw being connected to a connectin'g rod which carries the weight of the body directly and to footrests which are: also connected to the crank throw through a linkage for alternateoperation of the crankshaft by the inquest tion of the weight of a rider on the body then. on;

the foot rests.

A furtherobject is to: provide a. drive, as above described, in. which the crankshaft is so related to its actuating linkages that the tendency to stop at a dead center will be minimized.

A still further object is'to provide atoy horse as above described having-a single front wheel mounted for steering movements andmeans for steering, this wheel comprising handles or reins located at. or. near the horses mouth.

Other objects and advantages will become here inafter more fully apparent as reference is bad to the accompanying drawings in which Figure l is a vertical longitudinal section ;through my improved horse showing a crankline 3-1: of Figure 1,

Figure 4 is a side elevation of the operating mechanisms shown with the stirrup in depressed position, and

Figure 5 is a view similar to Figure 4 with the stirrup shown in elevated position.

More particularly, i indicates the body of a toy horse which is hollow in the interests of lightness of construction and in order to house the linkages hereinafter described. Pivotally secured inte'riorly of the body I at an intermediate point in the height and near the front end thereof are dual main supporting members 2 which parallel each other in mutually spaced relation and which extend downwardy and rearwardly to the region of rear wheels. A crank shaft 3 having a single crank throw is journalled in the supporting members 2, the two supports being located on opposite sides of the crank throw. Two spaced rear wheels 4- are fixedly mounted on the crankshaft 3 for rotation therewith. Pivotally connected at 52 to the interior of the body I above the crankshaft 3 is an elongated connecting rod 5 which is journalled at its lower end on the throw of the crankshaft 3. It will be noted that the pivot I2 is slightly rearwardly of a vertical line which intersects the axis of the crankshaft 3.

Intermediate the length of the connecting rod 5 an actuating link or lever B is pivotally connected thereto, this lever being fulcrumed intermediate its length by a roller 1 rotatably supported by a pin 8 which connects the two supporting members 2. A retainer 9' secured to the lever 6 forms a slot for contained travel of the lever on the roller.

The lever 6 has foot restsupports Ill pivotally connected thereto andde ending therefrom, a. bar

H extending laterally from each side of the sup ports Hi serving as rests for the feet of the rider.

A single front wheel !3 has an axle i4 journalled in ayoke I5 which is secured onto a substantially vertical steering shaft it. A bearing I? carried by. the lower part of the body i as athrust bearing and a second bearing i8 vertically above andaligned: with therbearing ll support;

3 the shaft it within the body I. The shaft i6 is bent at its upper end and a cross-shaft I9 is secured transversely of the shaft it in such manner as to form steering handles. The bend of the shaft [6 is at a height such that the handles i9 will extend outwardly from a slot 20 in simulation of the mouth of the horse.

The operation is as follows: When a rider is seated astride the horse I with his feet resting lightly on the foot rests H substantially all of his weight will be applied to the pin 52, the connecting rod 5 and the crankshaft 3 which will cause the throw of the crank to find a position below the axis of the crankshaft. The pin 12 extends from one side of the interior of the body to the other and is firmly anchored therein at each end so that the weight of the rear part of the body is transferred to rods 5 by the pin l2. Whether the lowermost position is vertically below the axis of the crankshaft will depend on the relative vertical position of the pivot 52. The oft-centering effect can be varied by selec tion of its position. If the pivot 12 is vertically above the axis of the crankshaft at the end of its downward stroke then the crank throw will be vertically below it. As illustrated in Figure '3, the pivot is slightly rearwardly of this vertical line V-V, so that the axis of the crank-pin will come to rest almost vertically below the axis of the crankshaft but very slightly in front of it. When the rider then shifts his weight onto the foot-rests II the lever 6 is rocked in a clockwise direction about the pin 8 and exerts upward force on the pivot 5b in the direction of the ar row 0, as indicated in Figure '7, this arrow indieating a tangent to a circle having its center at the top of roller 8 and a radius from that point to the pivot 51). Since the pin I2 is fixed in the body this force acts to swing the bottom of the rod 5 to the left and upwardly thus rotating the crankshaft 3 over bottom dead center in a clockwise direction which will continue, with continued pressure on the stirrups H, for approximately 180.

As the rod 5 is thus elevated the rear of the body is accordingly elevated, the body being thus rocked through a vertical are having its center at the axle Id of the front wheel. The pin :2 is thus carried relatively forwardly over the axis of the crankshaft 3 so that when the rod 5 attains its uppermost position, as indicated in Figure 6, a vertical line through the axis of the crankshaft will correspond approximately with line A.--B through the center of the pin l2 and this axis, the degree of approximation depending on just how far back of the vertical the pin 12 is set in the position indicated in Figure 7.

As the stirrups l l are depressed the lever t not only rocks about the fulcrum 1 across a horizontal line through the fulcrum but also rolls on the roller 8 so that when the rod 5 attains its maximum upward position there is still a force in the lever urging the pivot 5b to the right of the line AB which will carry the rod 5 past upper dead center by an amount indicated by the angle a. Thus, when the rider again shifts his weight from the stirrups to seated position his weight is imposed on the pin i2 and the crankshaft will continue to be driven in a clockwise position until the crankshaft reaches the position shown in Figure '3'. Alternate shifting of the weight of the rider from the stirrups to the body thus causes continued rotation of the rear wheels and, hence, continued forward movement of the horse together with a rocking movement about the axle of said wheels mounted on the ends thereof for rotation therewith, a connecting rod rotatably connected to a throw of said crankshaft at one end and pivotally connected to the interior of said body at a point substantially vertically above the axis of said crankshaft whereby the imposition of the weight of the rider on said body causes rotationof said crankshaft and wheels through a portion of a revolution, foot rests intermediate the length of said body, and a linkage having one member pivotally supporting said foot rests and having another member pivotally connected to said one member and pivotally connected to said connecting rod intermediate the ends of said connecting rod, the last named member being fulcrumed intermediate its ends whereby the imposition of the weight of the rider on said foot rests rotates said crankshaft and wheels through the remainder of a revolution.
