COIN-CONTROLLED MACHINE FOR ADMINISTERING ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 492,486, dated February 28, 1893.

Application tiled August 13, 1892. Serial No. 448,064. (No model.)

To cir/ZZ whom it' may concern.-

Be it known that l, WILLIAM RILEY POPE, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Coin-Controlled Machines for Administering Electricity, of which the following is a specication.

The object of my improvement is to produce a simple and inexpensive machine of such character that upon the introduction of a coin of predetermined denomination, it would be possible to obtain a shock or current of electricity.,

I willdescribe a machine embodying my improvement and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a front view of a machine embodying my improvement, part of the case being removed. Fig. 2 is a side View thereof with the case partially removed. Fig. 3 is a view of the opposite side with the case partially removed. Fig. 4 is a detailed View of certain parts showing the co-action of one of the handles with a part employed to move the secondary of the induction coil. Fig. 5 is an end view of a coin receptacle including its appurtenances. Fig. G is an end view of a coin receptacle including its appurtenances. Fig. 7 is a diagram illustrating the circuits.

Similar letters and numerals of reference designate corresponding parts in all the ligures.

A designates an induction coil consisting of a primary tt and a secondary a2. These parts may be of ordinary or any suitable construction. The primary a is immovablyconnected to a support B in a vertical position, whereas the secondary a2 is secured to said support so as to be capable of moving vertically and lengthwise of the primary d. The support B is represented as consisting of an upright board fastened to the lower section C of a case C C2. This case C C2 may be made of sheet metal. As here represented, the lower section C is provided with a basepiece c, on which the machine may rmly rest, and the upper section C2 slides down over the cylindric portion of the section C.

The support B may be secured to the section C of the case C2 by means of screws passing through the cylindric portion of the section C and entering the support.l The two sections of the case may be secured together by means of a rod c extending up through the top of the section C2 and having a padlock fitted to its projecting extremity.

Obviously the case may be made of any ornamental conliguration.

Outside of the case of the machine are two metal handles H' H2,represented as made in the form of door knobs. The handle H passes through the cylindric portion of the section C of the case C C2 and isfastened by a nut applied to a screwthread onits inner extremity. It may be clamped in suflciently tight to prevent it from being rotated, and if this is done, it is less liable to injury by force tending to turn it. The handle H2 is affixed to a shafthextendingthrough thecylindric portion of the section C of the case C C2 and passing into the support B. On this shaft within the caseare collars h h2 h3. The collar h is adjacent to theinner surfaces of the cylindricportion of the section c of the case C C2 and prevents the handle and its shaft from being detached. The collar h3 is capable of a sliding movement lengthwise of the shaft and is held with one sidein contact with the collar h2 bya spring h4, coiled around the shaft between the collar h3 and the collar It'. The opposite sides of the collars h3 h2 are provided with ahorizontal projection and recess. There may be any number'of the projections and any number of recesses. By means of said projection and recess the collars h3 h2 are normally engaged so that the collar h3 will rotate with the shaft, but the engagement between these collars is such that if anything prevents the rotation of the collar h3, it will move lengthwise of the shaft against the resistance'of the spring h4 and become disengaged from the collar h2. From the collar h3 projects an arm h6. After the rotation of the handle H2 a certain distance, this arm h6 will come in contact with a rod k7 projecting horizontally from the lower portion of the support B, whereupon the further motion of the arm will be arrested. The arrest of the arm h6 will not, however, interfere with the continued rotation of the handle H2 and its shaft, hence any attempt to force the handle beyond the point where it is IOO intended to move will not cause injury to the machine.

From the arm h6 a band h2 passes up over a pulley h2, journaled in a bracket fastened to a block b extending horizontally from the support B. The band h2 after passing around the pulley h1 is fastened to the secondary of the induction coil. Obviously, by rotating the handle H2 in one direction, the secondary will be raised and by rotating the handle in the reverse direction, the secondary will be lowered. Preferably a spring h1() will be employed to lower the secondary to its normal position. As shown, such spring is of helical coiled wire and is fastened to a metal screw a2 extending from the secondary of the induction coil and to a metal bracket a4 extending from the support B.

The upper section O2 of the case O C2 has notches at opposite sides of its lower portion, so that it may be slid down past the handles H H2.

D designates a battery, which may be of any suitable form. It may advantageously be a dry battery. It is shown as fitted in a holder which is fastened by a screw d to the support B.

From one pole or electrode of the battery D a wire, 1, extends. This wire passes through the supportBand is secured in a metal binding screw, 2, which is mounted upon a metal bracket, 3, secured to the support B. The bracket, 3, is provided with a metal contact point, 4, here shown as made in the form of a screw engaging with the bracket, so as to be adjustable. Below the contact point, 4, is arranged a contact point, 5, consisting of a strip of metal extending horizontally from a metal bracket, G. This bracket, 6, is provided with a binding screw, 7, from which extends a wire, 8. The wire, S; is shown as passing through the support B, thence up along one side of said support and thence from the support again to the same side as that upon which the brackets 3 and 6 are mounted. The wire then connects with one extremity of the coil of the primary a of the induction coil A. The movable secondary a2 of the induction coil is provided with a tinger a, which, when the secondary is lowered toits normal position, will impinge against the contact piece, 5, and separate it from the contact piece, 4. thus breaking the circuit which includes the primary of the induction coil. Whenever the secondary is raised, the finger a rises from the contact piece, 5, allowing it to impinge against the contact point, 4, so as to complete the primary circuit. As the secondary of the induction coil is raised and lowered by means of the handle H2, the circuit, including the primary of the induction coil, is opened and closed by means of said handle. From one end of the coil constituting the primary of the induction coil a wire, 9, extends to a binding screw, 10, extending" from a plate afiixed to the block b. From this binding screw, 10, extends a metal strip, 11, forming part of a rheotome, which at its free extremity is provided .with a piece of magnetic metal, 12, located over the core of the primary of the induction coil. Above the strip, 11, is a contact piece, 13, extending from a metal bracket, 14, provided with a binding screw, 15. From the binding screw,

15, a wire, 16, extends passing aerossthe sup port B and then downward to one pole or electrode of the battery'D.

The primary ofthe induction coilAis supported from the block b and extends downwardly therefrom. The secondary is guided by rods a a1, fastened at their upper extremities in a cross-bar a2, and at their lower extremities in a cross--bar a9. One end of the coil constituting the secondary of the induction coil is fastened toa metal plate d10, which is fastened to the upper extremity of the secondary of the induction coil and is in metallic contact with the metal rods a a7. The circuit of the secondary of the induction coil is therefore extended to this plate, thence to the said rods and from thence to the bar ai. From the bar a9, it is extended bya metallic clip L11 to a metal plate @12 fastened to the support B and receiving the shaft of the handle H2 through it. This shaft,being made of metal, is in electric communication with the plate @12, and hence extends the circuit to the said handle. The plate @-12 is provided with a metal binding screw a12, whence extends a wire @14. This wire passes through the support B and extends upwardly to a binding screw @15, which is connected to a metal plate a1, fastened to the support B, and constructed to form a bracket in which is fulcrumed a metallic lever I. The lever I at one end is provided with a coin receptacle t" and at the other end with a counterbalance t2. Normally the counterbalance holds the lever I in contact with a resilient metal finger (L17, extending from a metal plate @18 fastened to the support B,and provided with a metal binding screw a1. From this binding screw d1 a wire d20 extends through the support B and to a metal screw (L21, that extends from the metal plate a4 fastened to the support B. From the screw a21, there also extends a wire Q22 and this wire passes through the support B and connects with the metal shank of the handle II. From the screw @21, the circuit is extended through the metal spring 71.10, and thence to the screw as. One extremity of the coil constituting the secondary of the induction coil is fastened to this screw, thus completin T the secondary circuit.

Owing to the normal contact of the lever I with'the spring finger G17, the secondary will be normally short-circuited from the handles, but whenever a coin is deposited in a coin receptacle t', the lever will be oscillated so as to break the short circuit and thereupon the secondary circuit with be continued to the handles.

It will be seen that the primary circuit is normally open and the secondary circuit normally short-circuited. The movement of that IOO handle which adjusts the secondary of the induction coil, and thereby varies the shock or current of electricity administered, serves to close the primary circuit of the induction coil, and the deposit of a coin of proper denomination in the coin receptacle breaks the short circuit of the secondary coil. The coin receptacle has a bottom support i3, which will only serve to sustain a coin as large as the proper denomination. The coin aperture C10 of the case C C2 should be of such a size as to prevent any coin larger than that of the proper denomination from entering the machine.

The bottom support i2 of the coin receptacle is pivoted at 4 to tbe body of the coin receptacle. Said bottom support is rigid upon the pivot 4 and the latter turns freely in the body of the coin receptacle. One extremity of the pivot is bent to form an arm 5, which by co-acting with a pin @'10 will limit the rocking movement of the bottom support` s in each direction. The other extremity of the pivot is bent to form an arm t6. An arm Tis loosely mounted upon the pivot, so as to be free to oscillate thereon. It extends over the arm i5.

The secondary of the induction coil is provided with a rack bar J, comprising a number of pins j. The arm i extends across these pins. When the secondary of the induction coil ascends after the descent of the coin receptacle, the arm @"7 will be oscillated by the pins j of the rack bar .l upon the pivot 4 without affecting the bottom support i3 of the coin receptacle. The minute that the secondary is lowered, the pins j of the rack J will oscillate the arm i7 downwardly, and, as then this arm will impinge against the arm t6, the

latter will also be oscillated downwardly. This will cause the bottom s'hpport of the coin receptacle to be oscillated upwardly, so as to permit of the passage of the coin, which will then drop in to a receptacle K located in the lower part of the case C C2.

I have shown the section C2 of the case C C2as provided with a vertical slot fitted with a piece of glass and a graduated scale, S, arranged on one edge of the support B opposite an opening c5. An index S is attached to the secondary of the induction coil and extended over the scale, hence when the secondary is raised, the index will indicate the extent of the shock or current of electricity administered.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for administering electricity, the combination of an induction coil having a iixed section and a movable section, a
