OPERATING MEcHANIsM FOR AMUSEMENT DEVICES Fi1ed Jan. 25, 195s 2 sheets-sheet 2 INVEN TOR. Y vof A( DHA/vo United States Patent iilice GPERATING lVlECHANISM FOR AMUSEMENT DEVICES My invention relates in general to amusement de vices and more particularly to an improved operating mechanism for a mechanical horse or the like.

In mechanical horses of the type which a person can ride, it is desirable that the movement simulate as closely as possible that of a real horse. w Accordingly, it is desirable to have an operating mechanism capable of producing different motions and different speeds in such combinations as to provide gaits similar to those of a real horse. lt is also desirable, that the rider be able to control the mechanism to produce the gait desired.

Although there are mechanisms available which have these capabilities to some extent, they possess certain disadvantages. For one thing, the mechanisms do not produce movements which simulate gaits of a real horse as closely as desirable. Also, these mechanisms are complex and expensive.

Accordingly, lit is a major object of my invention to provide an improved operating mechanism for a mechanical horse which produces movements closely similar to those of a` real horse.

lt is another object of my invention to provide a mechanism capable of producing different motions and speeds in such combinations as to closely simulate gaits of a real horse.

lt is also an object of my invention to provide such a mechanism, which will change gaits in response to the movement of reins by the rider.

It is a further Vobject of my invention to provide such a mechanism which is simple to operate and inexpensive to manufacture and maintain.

These and other objects and advantages of my invention will be apparent from the following description (thereof, and from an inspection of the accompanying drawings, in which:

Figure 1 is a partially sectioned side elevation of a preferred embodiment of my invention;

Figure 2 is an enlarged side elevation of the actuating mechanism of Figure 1, shown simulating a trotting gait;

Figure 3 is an enlarged side elevation o-f the actuating mechanism of Figure l shown simulating a gallop;

Figure 4 is an enlarged plan view of the actuating mechanism of Figure 1;

Figure 5 is an enlarged side View of the guide and cam mechanism of Figure l; and

Figure 6 is an enlarged end `view of the actuating mechanism of Figure l.

Referring now to the drawings, and particularly to Figure 1 thereof, the numeral 10 indicates generallly an amusement device having a horse shaped body 11 and a supporting base 12. The supporting base 12 has stanchions 13 which pass through openings in the bottom of the body 11 and support a stationary platform 14 located inside of the body. A frame 15, also inside of the body 11, is mounted above the platform 14 on uprights 16. These uprights are pivotally connected to `the inside end of a bit member 44.

,and backward .Fatou-ated Dec. l, 1959 the platform at a connection 17 near the forward part thereof, thus rendering the frame movable in relation to the platform. The horse body 11 is mounted on the frame on cross supports 18 and is therefore capable of `being rocked forward and backward about the supporting base i2. An operating mechanism 19 is provided to actuate this rocking movement.

ln this embodiment, the operating mechanism 19 is mounted inside of the horse body 11 on the platform 14. The mechanism comprises a drive motor 20, a set of

reduction pulleys

21 and 22, and a linal reduction pulley 23 attached to a rotating shaft 24 which drives two crank arms 25 secured to the ends thereof. The two crank arms 25 are pivotally connected at their outer ends 26 to one of the ends of two elongated links 27, which in turn are pivotally connected at their other ends 23 to the mid-portion of two actuating arms 29. The actuating arms 29 are substantially vertical in their neutral position and are pivotally attached at their upper ends to each side of the frame A15 at rearwardly positioned connections 30.

As shown in Figure 4, an axle 31 connects the lower ends of the actuating arms 29 and has twoV outer rollers '32 and a center roller 33 rotatablyrnounted thereon.

of the rearmost position of the center roller 33 (see Figures 3 and 4). The forward end of the ramp 35 has a rod 36 athxed thereto which is pivotally mounted on brackets 37. The rear or distal end 38 of the ramp is free to swing up and down about this pivotal mounting. The rod 36 has a lever arm 39 attached thereto, the lower end of which is connected to the platform 14 by a spring 4). The tension of the spring 40 acting through the lever arm 39 and the rod 36 holds the rear end 3S of the ramp in an upward position, out of engagement with the center ro-ller 33 (see Figures l and 2).

Also attached to the lever arm 39 is a linkage 41 which connects to reins 42 on the body 11. The linkage 41 includes a exible cable 43 which is attached to the lower end of the lever arm 39 and is directed by pulleys 43a into the horses head, where it connects to The bit 44 is pivotally mounted in the horses mouth and has reins 42 secured to its outside ends. When the reins are tightened they draw back on the outer ends of the bit 44. This moves the inner end of the bit forward which in turn pulls the lower end of the lever arm 39 forward by means of cable 43 and lowers the rear end 38 of the ramp 35 so that it may be engaged by the center roller 33 (see Figure 3).

In operation, the drive motor 20 rotates the two crank arms 25 through the

reduction pulleys

21, 22 and 23. These crank arms 25 in turn drive the actuating arms 29 through links 27, pendulously about the pivotal connections 30. This causes the outer rollers 32, attached to the lower ends of the actuating arms 29, to travel back and forth along the track surfaces 34. Since the track surfaces are mounted on the stationary platform 14 and the upper ends of the actuating arms 29 are connected to the frame 15, this back and forth movement of the rollers forces the rearward portion of the frame 15 up and ydown at the pivotal connections 30. This up and down action causes the frame 15 to be rocked forward about the pivotal connection 17 thus rock- 3 ing the horse body 11 with respect to its supporting base 12.

Since the maximum upward movement of the connections 3f) is reached when the outer rollers 32 are at the center point of their back and forth travel, and maximum downward movement takes place at the forward and rearward end of this travel, the horse body 11 makes two rocking cycles per revolution of the crank arm 25. This movement simulates a trotting gait.

If the reins 42 are pulled back, the distal end 38 of the ramp 35 is lowered as previously described (see Figure 3). This positions the ramp for engagement by the center roller 33 upon its next forward movement. When the actuating arms 29 are drawn forward beginning a new cycle of operation, the center roller 33 rolls up the ramp 35, lifting the outer rollers 32 off of the track surfaces 34. The ramp 35 is constructed to give the rearward pivotal connections 30 greater upward movement than effected by the trotting action, and to give the maximum upward movement at the forwardmost point of travel of the center roller. Thus, the movement of the center roller 33 on the ramp 35 gives a greater magnitude to the rocking action of the body 11 and reduces its frequency one-half; that is, one rocking cycle per revolution of the crank arm 25. By this movement, the horse simulates a gallop.

When the reins are released, the ramp 35 is returned to its normal raised position out of engagement with the center roller 33 by the tension of spring 40 and the mechanism again causes the horse to simulate a trot.

As will be apparent from the above description of my mechanism, the contours of the ramp 35 and the track surfaces 34 may be modified to give a great variety of different actions to the horse. In this particular embodiment, the ramp 35 is inclined forwardly upward and reaches its highest point a short distance before the center roller 33 reaches its forwardmost point of travel. This gives a dwell effect to the gallop action at its point of maximum rise. Even small variations of this contour will bring about significant differences in the resulting action. It has been found however, that this particular contour gives a good simulation of a horses gallop.

To prevent the ramp 35 from jamming on center with the center roller 33, should the distal end 38 of the ramp be only partially 1owered at the instant the center roller 33 engages it, a guide and cam arrangement is provided (see Figures 4 and 5). A blade-like guide 45 is attached to one side of the ramp at its distal end 38 with a sharp edge 46 of the guide extending beyond the leading edge 47 of the ramp. A triangular wedge-shaped cam 48 is attached to the axle 31 adjacent the center roller 33 with a sharp edge 49 directed toward the guide. The axle 31 does not rotate so that the cam 48 and its sharp edge 49 are held in the same position regardless of the movement of the actuating arms 29. Since the guide 45 and the cam 48 present sharp edges to each other, it is impossible for them to jam when they meet. If the ramp is in a partially lowered position when the center roller 33 starts its forward movement, the guide 45 engages the cam 48 before the roller strikes the leading edge 47 of the ramp, and the ramps distal end 38 is directed either upward or downward depending on which of the two cam surfaces joined at edge 49 is contacted by the guide edge 46. Since the ramp 35 follows the guide 45, it is positively positioned either upward or downward before the center roller 33 engages its leading edge 47. If the ramp is down, the horse gallops, if up, he trots.

Means are also provided to insure that the rollers do not raise off of the track surfaces 34 or the ramp 35. To keep the center roller 33 from raising off of the ramp during the galloping movement, a limiter 50 is provided over one outer roller 32a (see Figures 3 and 4). This limiter 50 is positioned to engage the outer roller 32a if the center roller 33 is raised from the ramp, thus restricting the upward movement of the rollers.

During the trotting movement, the under surface 51 of the ramp 35 is positioned just above the center roller 33 when the ramp is in its raised position, by a stop 52 which engages the lever arm 39. Any upward movement of the outer rollers 32 from the track surfaces 34 is therefore restricted by the center rollers engagement of this under surface 51.

Although the usual purpose of the mechanical horse such as this is for use as an amusement device, it will be readily apparent from the above description that this horse can also be used for exercising or for learning to ride horseback. The realistic trotting and galloping actions produced by my operating mechanism provide the same muscular workout as an actual horseback ride and serve as an excellent means for instructing someone to ride these gaits without the hazards presented by a live horse.

While the particular embodiment of my invention herein shown and described is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of a presently preferred form of my invention and that I do not mean to limit myself to the construction and design herein shown, other than as defined in the appended claims.
