UNITED STATESl PATENT OEETCEo JOSEPH MASON, OF LONDON, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 468,955, dated ma model.) Patented in England Application tiled March 14,1891. sean No. 385,115.

To all whom it may concern.-

Be it known that I, JOSEPH MASON, electrician, a subject of the Queen of Great Britain, residing at London, in the county of Middlesex, England, have vinvented a certain new .or Improved Automatic Coin-Freed Machine for Giving Electric Shocks, (for which I have previously obtained Letters Patent in Great Britain, dated January 31, 1889, No. 1,757,) of which the following is afull, clear, and exact description.

My invention relates to an improved automatic coin-freed apparatus for imparting electric shocks, and has for its object to provide simple mechanism whereby a coin dropped into a suitable receptacle will become itself a part of the electric circuit or act as a contactmaker by a mechanical action.

In order that vthe invention may be fully understood, I have hereto annexed sheets of drawings illustrative thereof, such parts only .of the apparatus being shown as are neces` sary to explain my improvements.

As ordinarily constructed the apparatus consists of a box or case for containing the batteries, dac., such box being provided with a door in front, to which are fixed the handles by means of which the shock is conveyed to the person using the machine. Asaccording to my invention the whole of the mechanismisattached to the inner surface of the door, I have not thought it necessaryto show any other portion of the box or case.

In the accompanying drawings, Figure 1 represents an interior elevation of the door with the mechanism attached thereto; Fig. 2, a plan thereof, and Fig. 3 a front view. Fig. 4 is a partial repetition of Fig. 1, showing the parts in the position which they assume when the movable handle is turned round and contact made by means of the coin. The coinbox is here 'cut away, and the coin itself is indicated in dotted lines, and it will be noticed that the bolt N is raised clear of the stop n2, thereby allowing the bar D to move forward, while the lever H2, having been raised by the periphery of the coin, is in contact with the spring J, thus rendering the electric circuit complete.

February 16, 1892. January si, 1839, No. 1,757.

Fig. 5 is a plan View of Fig. 4t and shows the inclination of rack G under forward motion of the lever F.

Fig. 6 is a cross-section of the bar D and guides D2, taken through the line was of Fig. l.

Fig. 7 is a detail, full size, of the under side of the coin-box F, lever Ff, and rack G during the return movement of the coin -box, showing how the teeth of the 'ratchet-bar operate to remove the lever outward and so increase the opening of the coin-box suiiiciently to allow the coin to pass.

A is the door of the apparatus, to which are attached the usual handles A A2. The handle A is fixed by a nut a; but the handle A2 is mounted on a spindle a and is free to revolve.

B is an ordinary induction-coil provided4 with its core or armature B and vibrating contact-maker C. for securing the necessary alterations of the current. To the core B is connected a sliding bar D, the connection being effected by means of an angular bracket D. (Shown in Fig. 5 in detail.) The bar D is capable of sliding in a dovetailed groove formed in a plate D2, which is screwed to the door. This sliding of the bar occurs when the handle A2 is turned, and is effected by means of the jointed lever E, one arm of which is fixed to the spindle a and the other to the bracket D. Attached to the bar D by means of a bracket D3 is a rectangular frame F, rcsembling an oblong box without top or bottom, the interior of the box being of sufficient dimensions to allow a penny or other specified coin to pass through freely. The opening on under side of thebox is contracted by means of a lever F, pivoted at f and kept in position by a springf, connecting the longer end of the lever with a stud f2, fixed in the Side of the box. The shorter end of the lever is beveled in one direction in order that it may pass smoothly over a ratchet-bar G as the bar D slides in the direction of the inductioncoil. As it is intended that the unbeveled edge of the lever F shall engage with the rack on the return pivoted at g to a lug formed on the plate D2,

so that it will yield as the lever F moves formovement, the latter is Ward; but, being kept in contact with the end of the lever by the spring-g', the perpendicular edges of the ratchet-teeth will engage with the unbeveled edge of the lever F on the return movement and cause this lever to turn on its axis.l In so doing the longer arm of the lever will turn `away from the box or frame F, and so enlarge the opening on the under side. On a stud H, flxedto the door, is mounted a sleeve H,'to 'the outer extremity of which is fixed a flat lever-arm H2, the free end of which reaches the nearest side of the frame or box F, but does not rest thereon, being prevented from doing so by the adj Listing-screw h, which bears on a short arm h', fixed to the inner end of the sleeve H. Fixed to the door is a flat spring J, which projects over the lever-arm H2 and nearly touches the same.

Having mentioned the most important part of the apparatus, I will now describe the action thereof. In the normal condition the electrical circuit is broken in two placesviz., where the spring .I is not in contact with the arm H2 and Where the said arm H2 is not in contact with the box or frame F. In other places the circuit is complete, as will be readily seen by tracing the course of the conducting-Wires it being presumedvthat the handles are connected through the body of the person receiving the shock. If now a penny or other` specified coin be dropped into the chute vK, (not shown in Fig-2,) it will fall into the frame F, but will not pass through by reason of the lever F contracting the open# ing on the under side. The edge of the coin thus arrested remains projecting above the top of the frame F. The handle A2 being now turned, the bar D, and with it the frame F,

is drawn forward and the coin comes in contact with the slightly-upturned edge of the lever H2, thus closing one break in the circuit. As the bar and coin continue to travel forward, the end of the lever lI-I2 rises upon the coin, and in so doing comes in contact with the spring .I and the circuit is complete. The strength of the shock of course increases the farther the handle is turned round, the coin remaining in the frame F. On the release ,of the handle A2 the sliding parts are returned to their original position by means of the spring L, and as soon as this return motion commences the end of the lever F engages with the ratchet-bar G, With the result that, as before described, the coin is released and free to fall into a receptacle provided for the purpose. Thus the current is interrupted and the circuit broken. j

In order to afford a true indication of the strength of the current, a graduated scale is fixed on the outside of the door, in which is a slot m, through which passes a pin or stud, which is fixed to the sliding bar D. The outer end .of this stud carries an index or pointer pressed, this m', which travels along the scale as the bar 'is moved forward,

In order to prevent the fraudulent use of the apparatus, I provide a locking-lever N, which is pivoted on a stud n. The longer arm of this lever rests on the bracket D3, while the shorter arm is vin insulated contact with an arm n', fixed on sleeve H. On the bracket D3 is a stoppiece n2, which prevents the bar D from being moved forward if the proper coin is not inserted. When, however, the proper coinv is inserted, the lever-arm H2 1s raised, as before described, and simultaneously the arm n', fixed to the sleeve H', is dedepression being accompanied by a correspondingV movement of `the short arm of thelever N, whereby the longer arm is elevated clear of the stop-piece n2. As it is requisite that the bar D should travel forward a short distancebefore the arm H2 can be elevated sufficiently to cause the lever N to clear the stop ln2,the requisite interval is allowed between the end of the lever and the stop to afford time for this to take place.

Having thus particularly described my invention, ywhat I claim as new, and desire to seeure by Letters Patent, is

1. In a coin-freed mechanism for giving electric shocks, the combination, with the conv' ducting-wires and the handles, of the induction-coil, its armature and contact-maker, the coin-chute, the sliding bar connected to said armature, the jointed lever connected to said sliding bar andA one of the handles, the open frame located under the coin-chute, the pivoted lever lying across said frame to control the 'size of the opening therein, the swinging ratchet-bar engaging said lever and yielding to the pressure of said lever as the lever IOO moves in one direction and turning the lever as it moves in the other direction, and a movable circuit-closer H2, actuated by the coin in the open frame to bring it int-o contact with suitable parts to complete the circuit, substantially as and for the purposes set forth.

2. In a coinefreed mechanism,the combination, with the coin-receiving frame Fvand a spring-actuated lever connected thereto and lying across said frame to control the opening therein for the passage of the coin, of a swinging rack engaging said lever, a movable bar to which said frame is connected, and a movable circuit-closer moved in one direction to complete the circuit by a coin in said coinreceiving frame and automatically returning to its normal position after said coin has .passed from its receiving-frame, substantially as and for the purposes set forth.-

3. In a coin-freed mechanism, the combination, with the sliding bar D and the circuitcloser, of a locking-lever acting on said bar to prevent its movement until the insertion of the proper coin and having a portion of said Io adjacent to said lever N to bea-r on J[he latter to move it and unlock bar D when the sleeve lH is moved, substantially as and for the purposes set forth.
