PERPETUAL MOTION. 389 968. PERPETUAL MOTION. Alternate magnet type. The swing-ing of the outside magnets of oppositepolarity. Alternate the attraction andrepulsion of the magnets on the wheelto generate power to swing the outsidemagnets in and out of their sphere ofaction. Patented 969. PERPETUAL MOTION. Electro-magnetic type. In theengraving, A represents a frictional electrical machine ; B, a crank ; C, an electro-magnet ; D, wire con-ductors ; F, a trunnion; G, anarmature ; E, a circuit closer ; H, apitman ; I, an insulating substance ;and J, a spiral spring. The device is expected to operateas foUows: The frictional electrical machineis started, which magnetizes thetemporary magnet and draws the armature toward it. This breaksthe circuit at the point, I, E, which demagnetizes the temporary magnetand allows the spring, J, to again close the circuit. By this means acontinued motion is expected to be kept up. To those not familiar with the science of molecular physics this devicemay appear very plausible; a little reading, however, upon the subjectof the correlation of forces will serve to show its utter fallacy.
