TvVith the foregoing and other objects in view, the invention consists of the novel construction.I combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modiications can be resorted to which come within the scope of the claims hereunto appended.

ln the drawings wherein like reference characters denote corresponding parts throughout the several views Figure l, is an elevation of an electric shockingl machine in accordance with this invention.

Figures 2 and 3 are sectional elevations.

Figure il, is a top plan broken away.

Referring to the drawings in detail the mechanism ot' the machine is supported by a pair of frame plates l, 2, and between which the electromagnets 3, 4 are secured. @ne of the magnets is positioned between the frame plates at one end and the other between said plates at the other end. Operatively arranged between 'the frame plates l, 2 and also between the magnets 3, i is a four pole permanent magnet rotor 5, and which revolves freely within the pole shocks of the electromagnets 3, casing 6, is provided to enclose the mechanism of the machine and which is provided with a terminal cap 7, and 'the latter is insulated from the body of the casing or machine proper by a plate 8, of insulation. rl`he plate 8 is provided with an opening 8 for a purpose to be referred to.

rEhe electromagnets 3, l, include coils gtlt, connected in series, and with one end of the winding lgrounded to the machine, as at G, and tie other end connected to the short-circuit breaker 9, as at C. The breaker 9, is positioned at the outer side of the plate 2, connected therewith, by a pair of holddevices 9', insulated from the plate f2. i inner end of the breaker 9, is reduced, as at 9 and which forms a spring acting on a ratchet 5', to be presently referred to. to short circuit coils 3, et and to break the short circuit at predetermined periods. The shaft of the rotor, is indicated at 5 and the ratchet 5 is secured to one end of the shaft 5 at the outside of the plate The shaft 5 is mounted in the plates l, 2 and projects .from each of them. The ratchet 5 is scoured on the rotor shaft in a position with relation vided with a ratchet gear 5' arranged outside of the plate 1, and which employ/'ed for the purposel of revolving the shaft 5, so as to revolve the rotor The gear 5' is operated by a right and left ratchet fork 10, which is operatively connected to an operating lever 11, by a hinge joint 10. The friction of the joint 10 being so adjusted as to prevent movement between the lever and the fork only when the fork 10 is in contact with the ratchet 5', or during the power stroke or strokes, and in this connection it will bc stated, that on a forward motion ofthe lever l1, the lower leg of the fork 10 is thrown in mesh with the gear 5', while a rearward or backward motion of the lever 11, the upper leg of the fork 10 is thrown in mesh with the gear or ratchet 5. lVhen the motion of the fork 10 is slower than the gear 5', the fork is thrown out of mesh and to a central or neutral position, by the ratchet gear 5', but a. motion of the lever` in either direction, will again throw the fork into mesh, and revolve the rotor. The power stroke is in both directions, while the movement of the rotor is continuous in one direction.

The lever 11, is in the form of an inverted yoke, and the leg 12, is of greater length than the leg 13 thereof. The legs of the lever 11 are mounted on the pivot 14, which is seated in the plates 1, 2. The lower end of the leg 12 is rounded and is mounted in the seat formed in the fork 10 and which provides the hinge joint. 10. The legs of the lever 11. are arranged at the outside of the plates 1, 2' and the leg 13 has a curved spring bearing against the lower end thereof. The curved spring is indicated at 11 and acts against the lever 11 to hold it in the position shown` The top of the lever 11 provides a thumb piece and the lever is actuated by the thumb of the hand in which is holding the machine. As the backward motion of the thumb is the weakest. the spring 11 assists the thumb in returning the lever on the back stroke. as well as securing a more equal thrust on both strokes and less fluctuation rotation. at the same time securing the position of the lever when the magneto is not in operation.

The entire mechanism is enclosed in the casing 6, the latter is formed from conducting, but not magnetic material, and which forms the grounded terminal of the machine.

The plate S is secured to the end of the machine or rather casing or case 6, and the cap 7 is secured against the plate 8, by a holdfast device 147, which is mounted at the inner end of a. threaded socket l5, in the cap, and engages with the extension of the brake spring l. 'lhe extension of the break spring 9, is imlicated at 16, and is bent to extend forwardly of the platev 8, so that it can be readily engaged by the hold fast device 14. The threaded socket is employed to enable the attaching to the cap of a conductor (not shown) so that the shocking operation can be had at points removed from the device. The manner of setting up the break spring S, or rather the extension 16, provides a contact with the cap 7, thus the cap T and case 6 form terminals for the machine. The bottom of the case 6, is corrugated, as at 17, to facilitate holding of the machine.

The manner in which the machine is operated is as follows The machine is held in the hand with the -ap 7 projecting beyond the hand. An oscillatory motion is imparted to the lever 11, by the thumb of the hand holding the machine, causing thereby the rotor to revolve between the poles of the electromagnets 3, 4 and setting up an alternating current in the Windings, and which is periodically interrupted by the break spring 9, which is so adjusted to break or open the short circuit of the windings at a time when the current phase is highest, causing a physiological shock in the external circuit formed by the body. The frequency of the impulses is Within the control of the operator, the higher speed giving the higher frequency and corresponding shock.
