COIN-OPERATED ELECTRIC APPARATUS.

SPECIFICATION forming part of Letters Patent No. 528,911, dated November 6, 1894. Application lecl August 30, 1889. RenewedApril 7, 1894. Serial No; 506,774. (No model.)

To all whom," it may concern:

Be it knownthat l, JOHN H; ELFERING, a citizen of the United States, and a resident of the city of Cincinnati, in the Acounty of Hamilton and State of Ohio, have invented certain new and usefullmprovements in Coin- Operated Electric Apparatus, of which the following is a specification.

The several features of my invention and the various advantages resulting therefrom, will be apparent from the following description and claims.

In the accompanying drawings making a part of this specification,-Figure 1, Sheet 1, represents a view of the apparatus embodying my invention, as seen after the rear portion of the box inclosing said apparatus is removed. This figure may be described as a rear elevation of the apparatus proper. Fig. 2, Sheet 2, is a vertical transverse section from front to rear,of the apparatus, showing one of the operating handles and its connecting levers, and novel rack and pawl combinations, whereby certain novel and advantageous results hereinafter specified are attained, Said section being taken at the line e, e', of Fig. 1, that side of the section which faces toward the left in Fig. 1 being shown. Fig. 3, Sheet 2, is a vertical transverse section of my apparatus, showing the mechanism whereby the coin dropped'into the apparatus,

unlocks the handles and permits them to be raised. This section is taken at the dotted line z, z, of Fig. l, and that side of the section shown is the one which faces toward the left in Fig. 1. Fig. 4, Sheet 2, is a top view of the spring circuit breaker of the limiting device for making orbreaking the electrical current controlled thereby. Fig. 5, Sheet 2, is a top View of the clock mechanism operating as a part of saidA limiting device. Fig. 6, Sheet 2, is a rear view of the operating tube or rack which carries the core-sheath of the coil, and of the lever for engaging a stud on the said rod when the latter reaches a certain 'elevation. Fig. 7Sheet 2, is an end elevation of the clockmechanism for operating vthe tube or rack-which carries the core-sheathof the coil. This elevation is of that end of said mechanism which is at the right hand thereof in Fig. l. InFig. 7 the cord is shown wrapped around the pulley p2, as is necessarily the case before the cord is drawn down, and before the pulley p2 has been turned. Fig. 8, Sheet 3, represents in rear elevation, means of employing electric currents in my apparatus, and also means for starting the electric current through my apparatus, and for stopping the further fiow of said current, as hereinafter fully explained. Fig. 9, Sheet 3, is a vertical transverse section 0f a portion of the apparatus shown in Fig. 8, said section being taken at the dotted line y y, and that side of the section being shown which faces toward the left in said Fig. 8. Fig. 10, Sheet 1, is an enlarged elevation of the coil and its connections, and showing by solid and dotted lines, the directions in which the primary .and induced currents move. Fig. 11, Sheet 1, is a section taken at the dotted line y, y, of Fig. 1, that face of the section which faces toward the left 4being shown, the purpose of the section being to illustrate the junction of the lever 0.2 of the operating handle, and of the rod designed to close the electrical circuitand the immediate connections of the said rod. Fig. 12, Sheet 2, is a side elevation of the oscillating pendulum arbor and its connections with the balance wheel. Fig. 13 is a side detail View of the device for positively setting free the brake wheel from the action of the brake, in readiness for allowing the de` vice for increasing the intensity of the current to be duly set in operation. Fig 14 is a vertical central section from front to rear of one of'the handles, whereby the person desiring to receive the electric shock operates the apparatus, a portion of the lever to which the handle is connected being shown in similar section, the figure illustrating the preferred mode in which electrical connection is made with the handle.

A, A, are the handles to be grasped bythe person who is to receive the electrical shock or current. Each handle A is rigidly connected to a bent lever, having portions a', a2, the lever being pivoted on a bearing a3. (See Fig. 2.) At the inner end of each lever a', a2, is pivoted at a7, a double pawl having the pawls or limbs respectively marked d5 and as, rigidly connected together. A spring rack B has two recesses, respectively marked b and b2, adapted to receive the pawl a6. This spring rack is fastened at b3 to lever a2, and accom- IOO panics the lever a2 and pawl a6 in their ascent and descent. This spring rack B exerts its elastic tendency pressing against the pawl 0.6, and the point of said pawl will be either in the recess h2 or recess b as shown. A convexly curved stationary rack Whose radius is approximately the saine as that of the curve described by the inner end of the portion d2 of lever a', n.2, has recesses c adapted to receive the pawl c5. At the foot of this rack is a fixed arm c2, located as shown, and adapted to engage the pawl 0.5 as the limb a2 of lever a', a2 descends. Theends of the two arms a2 of the levers a', a2, are connected to a rod D, thereby securing among other objects unison in the ascent and descent of the handles A. These handles therefore rise together and descend together.

Before passing to a description of the otherI portions of my apparatus, I will describe the mode in which the said handles, pawls and racks operate in connection.

When the handles are dropped, they hang down as shown in Fig. 2, and the other parts of the mechanism are in the position shown in Fig. 2. As the handles are raised, the point of the pawl a5, being held in an elevated position by reason of pawl a6 being in the depression b2 of the rack, will pass down infront of and Without touching the rack. When the handles have been raised to a horizontal position, the point of the pawl a5 will impinge against the defiecting plate 02, and be turned toward the portion a2 of the lever a', a2. As the point of said pawl is thus turned, the end of the pawl a is forced out of depression b2 and into b', the elasticity of the rack B causing the depression b to lit over the point of the pawl a6 and hold it in position. As the handles are depressed part way, as shown by dotted lines in Fig. 1, the pawl a6 will be lifted, and will successively engage the successive teeth c of the stationary rack C. By these means the handles cannot be again raised to a horizontal position until they have been dropped to their lowest position. When thus dropped all the way down, the point of the pawls a5 is moved outward from the lever a2 by means of the deecting stud or projection c3, and the point of the pawl a is consequently changed from the recess b to the recess b2 of the rack. At the same time a suitable look, which forms a part of the apparatus, prevents the handles being again raised until a coin of a designated denomination is dropped into the apparatus. The preferred description of such lock to be employed is as follows, viz:-An inclined bolt L Whose operative end points downwardly and inwardly toward the front wall W of the apparatus, slides in bearings L', L', secured to a suitable support as L6. A slit or passage Way L2 is present in the said front Wall of the apparatnsand inclines downward and inward toward the coin holder L3. The coin holder L3 is provided with a vertical slit of a size sucient to receive the coin. The coin holder is provided with a transverse notch L4. This coin holder is rigidly connected to the respective levers a', CL2, of the respective holders, by means of the bar c4. When the handles are at their lowest point of depression, the holder L8 is in the position shown in solid lines in Fig. 3. The point of the bolt L then rests against the edge of the coin holder LS as shown in Fig. 3. When no coin is in the holder L3, the eleva tion of the handles will be prevented by the point of the bolt L entering the notch L4 and engaging the upper or vertical walls thereof, as the top of the holder is moved toward the bolt by the attempt to elevate the handles. After a coin has been dropped in the holder L3 the coin indicated by L5 fills the center of the notch and presents a rounded surface to the point of the bolt L. An attempt to raise the handles A will now be successful, for the reason that as they are elevated and the coin holder turned toward the bolt, the periphery of the coin acts as a cam and raises the bolt, the point of the latter slipping over the periphery of the coin and at the same time retreating upward, sliding in its bearings. As the handles continue to be raised, the coin holder descends, and assumes the position shown by dotted lines in Fig. 3, and the coin drops out of the holder and falls into a suitable receptacle L?, in the present instance consisting of a box attached to the rear side or door M of the apparatus, shown in Fig. 1. When the door M is closed,the box is in position beneath the coin holder. When the handles A are again dropped down, the coin holder slides back under the bolt L, raising the latter by means of the beveled surface L8 onit and the beveled portion L9 of the lower end of the bolt impinging against one another, and the surface L8 of the holder acting as a wedge or cam by lifting the bolt and at the same time passing by it. Thus the coin holder is returned to place, as shown by solid lines in Flg. 3, in readiness for another coin to be dropped therein, and in the meantime the coin holder is securely locked as aforesaid and the handles prevented from descending until the insertion of another coin in the coin holder. The bolt L is at all times prevented from falling too low by means of the pin L10 fixed thereto immediately above the upper bearing L.

N indicates a battery of any suitable description, preferably located as shown on the iioor of said box containing my apparatus. From one pole of this battery, the wire l runs to the spring armature k2, with which latter it connects, being preferably connected to the stationary base of the spring armature k2 through a screw connection as k3. A wire 2 is connected at one end to a lixed stud k, and at the other end to a fixed stud t. Against this stud, presses at all timos, except when removed by human agency, the spring 3. To

the rear end of this armature 3 is connected one end of a wire 4, whose other end is con- IOO erwise termed, an induced current.

therefore depresses this stud 7c.

nected to the coil S. That portion of this wire 4, which extends from the post n', (see Fig. l0,} to the coil is shown in dotted lines. Awire 5 is at one end connected to the other lpole of battery N, and at its other end is conthen be in communication with the coil byv way of armature post n3, armature h5, post n, and wire 5%. It will be observed that the connection between said post n3 and the armature 'a5 will be usually established (as shown) by means of the screw fn" of said armature, against the end of which screw ng the armature (when not drawn to the coil) presses, the purpose of this screw beingto adjust and keep the armature nearer to or farther from the coil as desired. The coil S is constructed in any of the well known methods for use in connection with a primary current and a secondary, or as the latter is oth- One of the handles A is put into connection with wire 6, one end of said wire being fastened to handle o? and the other to the coil S, that portion of the wire 6 which extends from post 'p7 to the coil being shown in dotted lines in Fig. 10. The other of the handlesA is put into connection with wire 7, one end of said Wire being fastened to the handle 0.2, and the other end to the coil S. That portion of the wire 7 which extends from the post its to the coil S is shown by dotted lines in Fig. l0.

The elevation of the handles A depresses the vertical rod K. This rod K slides in journals as 7a4, 7.04. This rod is connected to one of the levers a', a2, of one of the handles at the point 165, by a pivotal connection. The upper end of the rod is elastic, and this accommodates itself to the curve described by the pivot 105. Farther down on the rod K, a stud k is fixed to it. Depression of the rod The latter in its descent strikes against the free end of spring armature k2, and forces the latter against the stud 7a4. In this way, an electrical circuit is immediately formed, the circuit extending through conductors l, 2, 3, Lt and coil S, and thence through the coil by wire 5% through the armature and its posts to wire 5, and thence by the latter to the battery. This circuit magnetizes the cores of the coil S,

which latter then attract the free end of armature fr, and said free end moves forward and into contact with them. When the free end of the armature is in contact with the cores of the coil, the armature has left the post ne, and being out of contact with said post ne, theV primary circuit is broken. An induced current passes through wire 6, to the adjacent handle A, thence through the operator grasping the handles, thence through the other handle A, and thence through wire 7, to the coil. In this way, the raising of the handles communicates an electrical shock to the person holding them. When the primary circuit is broken, the core is demagnetized, and the armature is permitted to again spring back to the screw rtg of the post TLG. The induced current which passes through the partial circuit formed by the wires 6, 7, and handles A, as heretofore mentioned, and the person holding the handles and completing the circuit, is induced as frequently as the armature n interrupts the primary current.

The apparatus is provided with means for automatically causing the intensity of the electric current to be increased or-diminished after the circuit through the operator has been formed. The preferred form of this mechanism is4 as follows, viz: To the rod of( connecting the handles, is connected one end of a spiral spring P. The bar at the point where the spring is thus connected, is preferably formed into acrank as shown, or eye to prevent the cord from slippingr along the bar, in either direction from its proper place. The other end of this spring is connected to the lower end of a cord p', which latter passes up and over and around a pulley p2, and the upper end of the cord is fastened to the periphery of this pulley. This pulley p2 turns loosely on its shaft p27. At the side of the pulley p2 and concentric with the latter, is a pinion p4 xed to the sleeve p3 turning on shaft p27. A pawl p5 pivoted to the loose pulley p2 engages the pinion p4, when the pulley p2 is turned (when 'looking at Fig. l) from the right over to the left, that end of the cord p', which is attached to the spring P, being subjected to a downward draft by the elevation of the handles and the depression of the rod a7. A toothed wheel p6 is fixed on the pulley 102. Al rack S2 slides vertically, its reciprocating movement being kept in a vertical line by means of a suitable' guide, which latter, in the present instance, consists of a vertical rod S3 fixed at each end to the frame of the apparatus and passing through the rack S2. The rack S2 thus slides upon the rod S3, the reciprocal movement of the rack S2 being limited by means of stops S4, S4. The rack S2 is provided at or near its upper end with an arm S', and the latter extends over a portion of the adjacent end of the core and is connected to the sheath S5, surrounding the core of the coil S. Teeth of the rack S2 engage the teeth of the wheel p6. In connection with the wheel p is a train of wheels and an escapement for regulating the rotation of the wheelp, rotated by pulley p2. One description of such train is shown and consists of gear wheel p7 fixed on sleeve p3 turning on shaft p27, pinion p8 fixed-on shaft p9, which last named shaft also carries the escape-wheel p10. The escapement pawlp11 is fixed to and suspended from the shaft or pivot p18. The shaft p12 carries a' balance wheel p16, which latter pref- IOO IIO

IZO

erably carries on its periphery a half tooth or stud p19, for the better making frictional contact with the brake rod pls. Adjacent to the wheel p16 is the balance coiled spring p17, connected and operating in a mannner common to clock Work. The pawl p11 of the escapement beyond the pointp where it is pivoted, is provided with an extension rigid with it. The end of this extension is provided with a fork p15, between the prongs of which is a pin p14, rigidly fixed in the balance. Thus the oscillation of the escapement pawl p11 in one direction, turns the balance wheel p16 against the spring p17, and this spring operates to oscillate the pawl in the opposite direction.

As the operation of the escapement pawl and its wheel p10 is well known,further mention thereof is herefrom omitted.

The brake rod p18 is pivoted at one end p23 to the clockwork frame Q. (See Fig. l.) The middle portion of the brake rod rests upon the periphery of the wheel p16. Upon the opposite, viz: the free end of the brake rod rests one end of the lever p20, pivoted at 21 tothe frame of the apparatus. The other end of this lever 1920 projects across the rack S2, and close thereto, and is subject to impingement by the stud p22 of the rack S2 as the latter rises. The manner in which this portion of my apparatus operates is as follows, viz:

As the operator lifts the handles A, A, the rod CLT of levers a', a2, is depressed, and pulls the spring P and stretches it. Vhen the handles have been raised, the circuit aforementioned is closed, and the operator receives theinduced currentas aforementioned. The spring P, being strained, pulls upon cord p and rotates the pulley 212 and wheel p6. The rotation of this is rendered slow and uniform by means of the clock work train of wheel, escapement, balance wheel and spring aforementioned. The wheel p6, by its rotation, moves the rack SL upward thereby continually increasing the intensity of the current, passing through the operator until the stud p22 on the rack S2 strikes and elevates the adjacent end of the lever p20. The other end of the latter then presses down the brake rod p18 upon the wheel p16, and thereby stops all rotation of the latter, the stud pl aiding in preventing the wheel p16 from slipping under the brake. Thus further elevation of the rack S2 is prevented, and the maximum degree of intensity of the electric current to which the operator is subjected, is reached. Vthen the rod al is elevated to the position shown in Fig. 2, all upward strain on rack S2 will have ceased, and the rack S2 will then descend to the lowest point of its movement, and reassume the position shown in Fig. l. lVhen the handles are dropped, the tension on spring P being gone, the weight of the rack S2 and the connections rigidly attached to it, causes it to descend. As it descends, it turns the pulley p2 and winds the cord p thereon. The pulley being loose on the shaft p3, and the pawl p5 sliding over the pinion p", does not, during the operation of rewinding the cord, turn the clock Work, and is not retarded by said clock work. The frontend of the shaft p3 carries at the outside of the front Wall of the machine, an index lingerpQQ, which indicates on a dial on the outside of the said wall, the intensity of the current to which the operator is subjected. The finger and dial being at the front of the machine, are in full view of the operator.

The pressure of the brake p18 on the brake wheel p16, is preferably always positively relieved at the time the apparatus is put into position for giving a fresh electrical shock. The rear end of the brake beyond the point p23 where the latter is pivoted to the frame, is provided with an arm p27. To the free end of this arm is attached the upper end of a rod or cord p28, whose lower end is connected to the outer end of the spring arm p29, the inner end of this spring arm being properly connected to the frame of the apparatus. Vhen the handles A are elevated by the operator, the free ends of levers ct', a?, and the rod a7 are depressed. The rod a7 strikes the arm p2, and thereby draws down the rod 1928,

and the arm p27 of the brake p28. Thus the brake is lifted sufficiently to be out of contact with the brake wheel, and the mechanism for increasing the intensity of the electric current is immediately free to operate.

I will now describe certain novel means for limiting the duration of the electric current.

To the bar al connecting the levers a', a2, of the handles A is connected (see Fig. l) the lower end of a spiral spring E, and the upper end of this spring is connected to one end of a cord e', which latter extends up and around a loose pulley e2, and fastened thereto at one point and down the other side thereof, and thence extends down and its other end is there connected to the weight c, sliding vertically in the guideways e7, e?, connected to the frame of the apparatus. The loose pulley c2 turns loosely on shaft c3, carrying pinion e5 fixed thereto. A pawl e4 pivoted to the pulley e2, engages with pinion e5. A suitable train of clock work, doc., regulates the rapidity and uniformity of the rotation of pulley e2, when turning in the direction in which the pawl e4 engages the pinion e5. Such a train consists as followsz-Rigidly fixed to shaft e3 is gear wheel e8, which latter meshes with pinion e9, fixed on shaft cm. To this latter shaft is also fixed gear wheel e meshing with pinion cl2 on shaft cl3, which latter also carries escape-wheel e, fixed to said last named shaft. On a pivot shaft cw oscillates the escapement pawl ew. An extension of said pawl located on the other side of said shaft e16 from where the pawl proper is located, is provided with a fork whose prongs have between them a pin e fixed in the side of the balance wheel ela, the latter being fixed on pivot shaft e2", and connected to a balance spring ew, combined and operating in the man- IOO IIO

draws with it the weight e6.

membered that the elevation of the handles ner well known to all clock Work. The manner in which this portion of my apparatus operates is as follows:

The handles being elevated and the rod a7 depressed, the spring E is stretched. The latter draws elastically upon the cord e and rotates the pulley e2 as fast as the clock work will permit. As the cord on one side of the pulley is drawn down by the spring E, it is drawn up on the other side of the pulley and It will be reclosed the circuit, and started the induced current through the operator. After a given time, the top of weight e6 will have risen to the bottom of spring circuit breaker 3. The cord c passes freely through a small opening in the end of this armature 3; but this opening is too small to allow the weight e5 to pass through it. Consequently as the weight e5 rises and strikes the bottom of the armature, it lifts the spring circuit breaker 3 off of the connecting stud t,and breaks the electrical circuit. The circuit now no longer vpasses through the apparatus, nor through the operator. For the latter to obtain a new electrical shock, he must drop the handles, whereupon theywill be locked. He must then drop in a second coin in order to unlock the handles, so that he can raise them. When the handles are raised, the strain on the spring E is withdrawn and the weight falls, the pulley rotating with it and its pinion c5 raising the pawl and slipping beneath it, the clock work standing still. The stud z" above the spring circuit breaker, 3, performs the office of a detent and prevents the weight e5 as it lifts' the spring circuit breaker, 3, from lifting the latter too high. y

By the mechanism heretofore described, the operator in order to prevent the intensity of the electrical'circuit increasing, has been obliged to cut it off altogether by dropping the handles, as shown in Fig. 2.

I will now describe a means whereby the operator, while experiencing the electrical current, can, at will, prevent the current from .increasing without breaking the electrical circuit, and can therefore enjoy any given degree of intensity of electrical force indicated on the dial during the entire time allotted by the mechanism, of which spring E, weight'e6 and spring circuit breaker 3 are elements. These means are illustrated in Figs. 8 and 9.

It may be here remarked, that the use of the means aforesaid is not to be confined to the modification of electrical circuits shown in Fig. 8, but is to be usedin connection with those circuits employed in Fig. l, or any other suitable circuits employed in the apparatus.

The mechanism shown in Fig. 9, and in elevation in Fig. 8, is in the latter gure shown in connection with said modification of electrical currents for the sake of compactness. It may be here premised that when this mechanism shown in Fig. 9 is to be einployed the mechanism consisting of rod K,

stud k', guideways 104, h4, armature 7a2, part los, and stud 7a4 will be dispensed with and the mechanism of Fig. 9, will take their place. To the frame of the apparatus is attached an upper bracket V10 and a lower bracket V5. In the upper bracket V10 is journaled one end of an arm V4, whose outer end is pivoted at V13 to the upper end of a vertical rod V5, the lower end of 'the latter being pivoted at V14 to one end of an arm V2, pivoted at V9 to the lower bracket V5. The other end of the arm V2 extends beyond the pivot V2 and toward the wall W of the apparatus. This free end of the arm V2 is continually engaged by a Spring arm rack V5, suitably attached, prefverably as shown, to the bracket V5, and having a single tooth on the lower side of which is the depression V8 of this rack.` On the upper side of the said tooth is the depression V7. The spring rack V5 continually presses outward against said free end of said arm V2. This arm V2 carries the curved downwardly projecting circuit-closer V so located, as shown, in relation to the stationary conductor V, as that when the arm V2 descends, the circuit closer V will descendv and come into contact with the conductor V and close the circuit. To the con ductorV is connected the wire .1, which latter thereby connects one pole of the battery to the said conductor. To the bracket V10 is connected the lower end of the conducting wire 2 whose upper end is connected to stud t, as aforementioned. The cross-rod a7 of levers ft2, a2, passes between the arms V4 and V2. The mode in which this portion of my apparatus operates is as follows:

When the handlesA are down as shown in Fig. 2, the position of the mechanism will be that shown in solid lines in Fig. 9, the rod a7 having lifted the parts to that position, the free end of the arm V2 being in the notch V8 of the rack V5, and the circuit closer V being elevated and out of contact with the conductor V. As the handles A are lifted, the rod a2 gradually descends. The arms V4, rod V3, arm V2, and circuit closer Vremain stationary'and do not descend with the rod a2, being held in position by thespring rack V6 which notch V8 and the free end of arm V2 continue interlocked, until as the handles A are continued to be elevated, the rod a7 in its downward descent strikes against the upper side of armV2, forcing the free end of said arm ont of the notch V5, and depresses the arms V4, V2, rod V3 and circuit closer V to the position shown by dotted lines in Fig. 9,the circuit closer resting against and in electrical contact with conductor V. This circuit closer together with arms V2, V4, and rod V5, continues to maintain this position, being held therein by the spring rack pressing against the free end of the arm V2, and pressing said free end upward. The electrical circuit is from the battery and wire 1 through the meehanism shown in Fig. 9, viz: lconductorV,ci1-cuit closer V arm V2, rod V2, arm V4, and bracket ICO IIO

V10, and thence by way of wire 2, to the coil and thence to the battery, the induced current being carried through the operator, all substantially as heretofore already shown and described in connection with Fig. l.

It is evident that for the arm in its upward movement to impinge against the arm V4, and elevate it and thus break the circuit, it, the said arm, must travel much the larger portion of the arc through which it travels when the handles are depressed. This construction of the parts thereby enables the operator, after elevating the handles and closing the circuit, to at any time once partially depress the handles and elevate rod a7 sufficiently to remove the tension from the spring arm p29 and thus allow the brake p18 to act on the brake wheel. The instant the operator does this, the rack S2 will cease to rise and all further increase of intensity in the current will be stopped. The rack S2 could be again started in its ascent, by a second partial elevation of the handles and a corresponding depression of the rod a7 and a consequent renewed release of brake-wheel, without breaking the circuit, that is, disturbinglr the position of the parts of Fig. 9, as shown in dotted lines therein, were it not for the fact that the pawl a5, after the first complete elevation of the handles necessary to close the circuit has assumed the position shown in dotted lines in Fig. 2, thereby permitting the handles to be dropped as far as desired, but preventing their elevation again, and consequent further depression of the rod al until the handles A, A, have been entirely dropped and the rod al elevated to its highest point of movement as shown in Fig. 2, and as heretofore fully specified. Thus it will be observed that the operator is thereby enabled to check the increasing intensity of the electrical current and at the same time enjoy the electric current at any of the given rates of intensity indicated on the dial, until the mechanism in which spring E and weight e6 and spring circuit breaker 3 play a part, or mechanism the equivalent thereof, after a given time, break the circuit, and cut olf the electrical current from the operator until the handles are dropped and the apparatus unlocked by the insertion of another coin.

I will now proceed to describe a modification of the electrical circuit, which modification although not as desirable as the system of circuits shown in Fig. I and heretofore described, I may yet wish at times to employ. This modification consists in attaching the wire 6 to the posta6 of the armature, and the wire 7 to the post n. In this way, a primary or galvanic current is transmitted to the person holding the handles. If I employ this modification, I do not use the secondary wire on the coil, and said secondary coil may be omitted. In such event, the coil wrapped with a single wire, in connection with the core and circuit breaker as described, transmits an intermittent primary current, theintensity of which is regulated by the sheath as in the induction coil.

While the various features of my invention are preferably employed together, one or more of said features may be employed without the remainder, and in so far as applicable, one or more of said features may be employed in connection with apparatus for similar pur poses, but of construction differing in many respects from that hereinbefore specilied.

That I claim as new and of my invention, and desire to secure by Letters Patent, is-

In a coin controlled electric device, the handles A, levers ct', a2 connected thereto, transverse bar a4 connectingr said levers, the coin receptacle L3 attached to the bar a4, and havingatransversenotchL5,tl1eslidingboltL, which when the coin receptacle is empty engages said notch when one attempts to raise the levers a', the coin receptacle L3 being provided with the vertical slit or receptacle intersecting said notch, for enabling a part of the periphery of the coin to fill said notch so far as the bolt L is concerned, and coin passage way leading from the exterior of the case to said coin receptacle, substantially as and for the purposes specified.
