Abstract: 177,930. Earle, K. J. Feb. 8, 1921. Self-driving machines and plant.-In a self-driving motor, means are provided for causing a body to travel in an elliptical or partially elliptical orbit by varying the rate of revolution of the shaft driving it, and energy is derived from a reciprocating member in contact with the moving body, part of the energy being applied to do useful work and part to maintain the body in motion.' Fig. 3 shows an example of the kind of moving body to be employed, the weights B moving in elliptical paths as the shaft D rotates with varying speed and reciprocating motion being imparted to members H in contact with the weights. Fig. 24 is an elevation and Fig. 25 a plan of mechanism for imparting varying speed to a shaft. A disc X<1> mounted on a shaft D rotating at constant speed, drives a disc W<1> mounted on an annular shaft D<2> through transmitting wheels V<1>, the axles C<2> of which are caused to oscillate between the positions shown in full and dotted lines respectively. In the position shown, the disc X<1> is driving the disc W<1> at its maximum speed: when the planes of the wheels V<1> are vertical, the discs rotate at equal speeds; and when the wheels V<1> are in the position shown by dotted lines, the disc W<1> rotates at its lowest speed. The movement of the axles C<2> of the wheels V<1> is effected by means of quadrants A<2> operated by a shaft A<1> to which a vertical reciprocating movement is imparted by cams J<2> mounted on a shaft D<3> geared to the shaft D.
