Abstract: 189,802. Lindh, J. Dec. 3, 1921, [Convention date]. Exercising-apparatus.-Relates to a mechanical horse to be used as an exercising-apparatus, and consists in mounting the horse on a frame in such a manner that the front and rear ends of the horse's body are moved separately so as to impart a curvilinear movement to the saddle. As shown in Figs. 1 and 2, the rear end of the horse is provided with an eccentric sheave 10 adjustably secured by means of a strap 19 on a crank 9 mounted in bearings 2 on the frame 1. The crank is rotated by means of worm and chain gearing from a motor 13 and imparts a circular motion to the rear end of the frame 7, the extent of the motion being adjusted by turning the sheave 10 about the crank 9, nuts 20 being used to secure the sheave. The front end of the frame 7 is mounted on a pin 12 in a frame 6 which is pivotally mounted in a pedestal 4, either hanging as shown in Fig. 1, or upright, as shown in Fig. 4. A reciprocating movement is thus imparted to the front end of the frame 7 by the rotation of the crank 9. Springs 21, 22, connected at their outer ends to the frame 1 and at their inner ends to a spring 23, assist in the upward movement of the frame 7, the spring 23 being connected to a downward extension 24 of the frame 7. The tension of the springs 21, 22, 23 is so adjusted that at the end of the upward movement the springs 21, 22 are horizontal, while at the end of the downward movement the angle between the springs is approximately 120‹. The distance between the inner ends of the springs 21, 22 may be adjustable and means may be provided to adjust the distance between the connections of the springs to the frame 1. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also means whereby the path of the saddle and the speed may be controlled by the, rider, as shown in Fig. 1 (Cancelled). The rear end of the frame 3 is secured to the strap 9 of an eccentric 8 that is rotatable. on a crank 7 on a shaft 4. The eccentric 8 is connected to the crank 7 by a differential gear controlled by brake-bands 31 connected to reins 33. By pulling one or other of the reins, the eccentric can be caused to rotate backwards or forwards relatively to the crank shaft and the movement of the body is varied accordingly. The socket arm 5, carrying the front end of the frame 3 is similarly mounted on an eccentric 39 pivoted on a shaft 6, which is fixed, and the centre of oscillation can be adjusted, to vary the reciprocating movement of the front end of the body, by rotating the eccentric. This is done by the rider pulling a cord 43 which causes a pawl 41 to engage a ratchet wheel 40 secured to the eccentric, so that the oscillation of the arm 5 causes rotation of the eccentric. The speed of the motor is regulated by a rheostat 62 controlled by reins 55. By pulling one of these reins repeatedly, the rider may increase the speed of the motor, and by pulling the other, a pawl is disengaged, which allows a spring to stop the motor. The rebound springs 49 may be adjusted by a right and left handed screw. This subjectmatter does not appear in the Specification as accepted.
