DAVID WEDGEWOOD, OF PETERBORO, ONTARIO, CANADA.

COIN-CONTROLLED APPARATUS.

Specification of Letters Patent.

Patented April 7, 1908.

Application led May 29, 1906. Serial No. 319,372.

To all whom it may concern.'

Be it known that I, DAVID WEDGEwooD, a subject of the King of Great Britain, residing at Peterboro, in the Province of Ontario and Dominion of Canada, have invented new and useful Improvements in Coin-Controlled Apparatus, of which the following is a specification.

This invention relates to an improvement in coin controlled apparatus designed primarily for attachment to electric meters and adapted in use to control the operation of the meter, and therefore, the supply of current, for a predetermined time in accordance with a coin to be deposited in the apparatus.

The main object of the invention is the construction of an attachment of the class described in whicha plurality of coins may be successively introduced during, or previous to the operation of the machine, the construction providing for the automatic control of the machine by such coins in succession, whereby a number of coins of the predetermined value may be introduced into the machine and the automatic operation of the latter maintained in ratio corresponding to the cumulative amounts of the deposited coins. y Y

The invention in its preferred details of construction will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a perspective view of a device constructed in accordance with my invention. Fig. 2 is a vertical section of the same, elevation. Fig. 3 is an end view of the same, and Fig. 4 is a section on line 4-4 of Fig. 2.

Referring particularly to the drawings, my improved apparatus comprises a base 1, preferably positioned immediately adjacent the ordinary form of electric meter (not shown). The motor shaft 2, common to such meters, is extended beyond the meter casing and terminally provided with a worm gear 3, said shaft being preferably supported in a bracket 4 rising from the base 1.

Thecircuit breaker included in the apparatus is supported on the base 1, preferably including a cylindrical receptacle 5 supported directly upon the base, the bottom of the receptacle being provided with a binding post extension 6 to project through and The upper surface of the receptacle bottom is provided with contact points 7, preferably three in number and arranged in a concentric plane, as clearly shown in Fig. 4. The binding post 6 is, of course, in metallic connection with the points 7, so that said post serves in effect as an extension. of said points. The receptacle 5 is provided with a cover 8 designed to close the upper end thereof and formed with a central opening 9 to receive a gasket 10, preferably of yielding and insulating material, as rubber or the like. A plunger 11 is movable through the gasket 10, carrying at its lower end a head 12 designed when the plunger is at the limit of its lower downward movement to engage and form an electrical contact with the points 7, as will be obvious. The plunger 11 is, in effect, a binding post for the second terminal of' the brake, being for such purpose provided with an opening 13 and a set screw 14 traversing the plane of the opening, as is usual.

Bracket arms 15 extend in spaced relation from the cover 8, vpivotally supporting at their upper ends, a lever 16, hereinafter termed the contact lever. Rearwardly beyond the pivotal point, the lever is extended in the form of a rod 17, on which is adjustably mounted a counter-poise 18 designed to overbalance the forward portion of the lever and to normally maintain the rear end thereof depressed. The upper end of the plunger 11 is provided with a bifurcated bracket 19, the vertically extending arms of which are pivotally connected to the lever, in advance or forward of the pivotal point. By preference, the body of the lever comprises a rectangular block 20 in the rear end of which is secured the rod 17 while in the forward end is secured a pair of superimposed plates 21 arranged for clamping engagement through the and centrally and longitudinally provided with semi-cylindrical recesses in their approximate faces to provide for the reception of a rod 23 extending forwardly from the lever to the desired extension. While preferring this specific form of lever, it is obvious that the same is not primarily essential, and I contemplate any specific constructionof lever that may be desired. The rod 23 at some distance forward of its connection withV the lever body, is bent upwardly into U form, as at 24, to provide for the downward movement of the lever without interference with the operating parts to be later described. The forward end of the lever is bent at an medium of screws 22l angle to the main length thereof, as at 25, with the terminal of such portion bent laterally to provide an extension 26, for a Vpurpose which will hereinafter appear.

A coin chute 27 is arranged at the forward end of the base, said chute comprising the usual face plates outwardly bent at the upper end to provide a flaring mouth and including an interior space of a size to receive the predetermined coin. At the lower end, the chute is widened, as at 28, in one direction, and the interior of the chute is in open communication through an alined slot 29 in the 'base with any desired form of coin receptacle, for the storage of the coin. The plates of the chute are each provided with a centrally arranged, vertically extending slot 3() to provide an opening in the chute for the reception of the angular portion 25 of the arm 23, the lengths of the slots 3() serving to limit the respective movements of the arm. The lever arm 23 is so positioned within the opening in the ychute that the lateral extension 26 at the free end of said arm is normally disposed in advance of the forward wall of the chute and wholly to one side of the plane of the opening.

To provide for locking the contact lever in operative or contacting position, I provide a bar 31 and mount the same for sliding movement through an opening 32 formed in the chute below the slots and slightly to one side thereof. The rear end of the bar 31 is ivotally Vconnected to the lower end of a cam ever 33 pivotally supported intermediate its ends upon a bracket 34 projecting from the ibase, and bifurcated at its upper end to provide arms 35 arranged to seat within a peripheral groove 36 of a disk 37 eccentrically supported upon a rod or shaft38, so that the revolution of said disk will rock the lever 33 and thereby reciprocate the bar 31. The shaft 38, which is disposed transverse to the length of the base is supported yat one end in a bracket 39, and at the opposite end in the bracket 4, said latter end of the shaft being provided with a pinion 40 in mesh with the worm gear 3 Von the motor shaft 2 hereinbefore described. By this construction, the

operation of the motor will cause a reciprocal movement of the bar 31.

Forwardly beyond the chute, the rod 31 is provided with an angularly extending arm 41, the u per end of which is provided with a rearwardly extending pin 42, designed to operate through an o ening 43 formed in the wall of the chute, so t at in the reciprocation of said bar, the pin 42 will be projected transverse the coin space within the chute. In rear of the chute, the bar 31 is provided with a second angularly disposed arm 44 provided at its upper end with a forwardly projecting pin 45 designed to enter an opening 46 formed in the Wall of the chute, so as to arrange the pin transverse the coin opening in the operation of the bar. The

arms

41 and 44 are disposed at slightly different angular relations with the bar 31, and are of di'erent lengths. The -arm 41 'is disposed at such angle relative to the bar 31 that the pin 42 of said arm coperates with the extended ortion of the chute in alinement with one wall of the coinway in the chute above the extension, while the arm 44 is of greater length than the arm 41 and disposed at aless angle to the bar 31. The pin 45 of the bar 44, by this arrangement, cooperates with the coin chute practically at the juncture of the extension therewith, and within the plane of the coinway, so that the pin 45, when disosed transverse the coinway, is in the plane of the descending coin, while the pin 42 is slightly beyond the edge of the operative coin, as will later appear.

One of the conductors, as 47, leads from the meter unbroken to the point of application, the remaining conductor 43 being connected to a binding post 49 fixed in the base 1, from which binding post, a conductor 50 extends to the opening 13 in the plunger 11, thus arranging one contact of the circuit breaker in the circuit, a conductor 51 leading from the binding post 6 of the fixed contact to the point of application. lt is, of course, understood that the current within the meter is to be directed to a suitable resistance if desired, so as to avoid burning out of the meter.

ln the normal position of the parts, the free end of the bar 23 of the contact lever is disposed at the upper end of the slots 3() of the coin chute, being limited in movement by the upper wall of said slots. The cam disk 37 is disposed at its forward limit of throw; that is, in a position to maintain the locking bar 31 in fully retracted position. The relative disposition of the pins 42 and 43 of this bar is such that when one of said pins is within the coinway, the other is removed therefrom, tion of the parts, the pin 42 is disposed transverse the coinway, while the pin 45 is wholly withdrawn therefrom. Assuming the parts in this position, the introduction of a coin of the predetermined value into the coin chute will depress the contact lever to the limit of downward movement, causing the plunger 11 to be depressed and engage the fixed contact 7, thereby establishing or completing the circuit in an obvious manner. The motor carried by the meter being started on the completion of the circuit, revolves the shaft 2 and, through the pinion 40, operates the cam disk to project the bar 31 in a forward direction. The relative arrangement of the bar 31 with the lower wall or limit of the slots 30, angular projection of the end 25 of the contact lever, is such that in the lowered position of said lever, the lateral projection 26 so that in the normal posi- 1 in connection with the thereof is disposed slightly in advance and below the operative plane of the forward end of the locking bar 31. As this bar advances, the pin 42 is withdrawn from the coinway and the coin permitted to move laterally into the extension 28 of the coin chute and drop into the coin receptacle. The forward movement of the bar 31 also disposes the free end thereof above the lateral eX- tension 26 of the contact lever, holding said lever in lowered or contacting position. This position of the bar 31 will be maintained until the cam disk has made a complete revolution and withdrawn the end of the bar from holding position with relation to the lever, so that the contact and, therefore, the s upply of current will be maintained during a practically complete revolution of the cam disk. As the revolution of the shaft 2, and therefore the movement of the cam disk, may be regulated in accordance with the amounts of current to be supplied for the particular coin, it is obvious that an equal amount of current will, in the operation of the machine, be always supplied under the influence of the particular coin. The withdrawal of the bar 31 from holding position permits the counter-poise 18 to return the lever to normal or elevated position, thereby breaking the circuit and cutting olf the supply of current at the point of use.

The above operation has been described in the use ofthe machine with a single coin. It is highly desirable, however, in order to avoid unnecessary delay and momentary lack of power, that a number of coins of the predetermined value be deposited in the coin chute. Provision is made in the above described structure for such deposit of duplicate coins, which are so supported as to have successive operative effect upon the mechanism.

Referring particularly to Fig. ,3,v wherein is illustrated a plurality of coins, it will be noted that the lowermost or operative coin is disposed upon the free end of the contact lever with the edge resting `against the pin 42. The second coin is resting above and in contact with the operating coin, and also above the operative path of the pin 45 of the arm 44. With a number of coins arranged in the chute for successive operation, the forward movement of the bar 31 under the influence of the cam disk will withdraw the pin 42 from engagement with the operating coin and permit said coin to move intov the coin receptacle, as previously described. This movement of the bar 31' also proj ectsl the pin 45V transverse the coinway and thereby supports the second coin in elevated position. In this arrangement of the parts, the contact lever is being held inoperative position by the bar 31, the operating coin having been discharged into the coin receptacle. As the bar 31 returns to normal position, tending to permit the contact lever to moveto inoperative position, the pin 45 is gradually withdrawn from the coinway, permitting the second coin to fall on to the contact lever and hold the same in operative position until the bar 31 returns to a fully projected position and locks the lever. The coins are thus successively and automatically moved into operative relation with the lever, the locking bar 31 serving, when returned to normal position, to permit a breaking'of the circuit, to automatically release the lowermost coin and permit it to gravitate to an operative relation with the contact lever.

The device is wholly automatic, and the length of current supply is limited solely by the number of coins placed in the coin chute. As said chute may be of any size desired, it is obvious that the apparatus permits of the deposit of any number of the predetermined coins at one time, which coins are successivel'y and automatically disposed in operative position in the operation of the apparatus.

Having thus described the invention what is claimed as new, is
