The present invention relates generally to electrically. operated fare boxes which, in response to insertion of a coin of predetermined denomination actuate a coin counting register and issue a ticket receipt.

It is a broad object of the present invention toprovide an improved electrically operated fare box.

It is a further broad object of the invention to provide an improved electrically operated fare box which, in response to insertion of a coin, actuates a register and issues a. ticket receipt.

It is a further object of the invention to provide an electrically operated coin controlled fare box which is responsive in its operations to a plurality of coins simultaneously inserted in the machine, to operate a counting register once for each of the coins, and to issue a ticket receipt for each of the coins.

It is another object of the present invention to provide a device which, in response to the insertion of a coin, initiates a cycle of operations including ticket feed, ticket separation by means of a cutting operation, counting, and deposit of the coin in a suitable receptacle, after which the device is readied for a succeeding similar operation in response to a further coin, deposited simultaneously with the first coin, or at any time thereafter.

Another object of the invention resides in the provision of a coin controlled fare box which is reliable in operation and economical of construction, and which readily lends itself to maintenance.

The above and still further objects, features and advantages of the present invention. will become apparent uponv consideration of the following detailed description of a specific embodiment of the invention especially when taken. in conjunction with the accompanying drawings wherein:

Figure 1 is a plan view of a fare box in ac:- cordance with the present invention;

Figure 2 is an elevational side view ofv the structure of Figure l, with chassis plates removed;

Figure 3 is a view of the structureof Figure 1 in front elevation;

Figure .4 is a viewin rear elevation, corresponding generally with the structure illustrated in Figures 1 and 2; and v Figure 5 is an elevational. view of a mechanical detail to the structure.

Brieflydescribed the; present invention is a coi p ed dev ce h c s driven by an electric motor. The latter is energized in response to insertion of a coin into the apparatus, and when. energized executes successive forward rota tions and reverse rotations of predetermined extent. Energization of the motor occurs in re sponse to insertion of the coin into the apparatus, by virtue of the fact that the coin when inserted bridges a pair of contacts which are in series with the motor and with a power supply line for the motor. In the course of a cycle of operations of the motor, consisting of one forward and one reverse rotation, the coin is released from icetween the contacts, terminating the cycle in the absence of a further coin in the coin chute. Should such a further coin have been deposited in the coin chute either simultaneously with. the first coin, or during the cycle of operations, the second coin again bridges the contacts, and the motor executes a further cycle of operations. Should no further coins exist in the coin chute the motor becomes deenergized.

During forward rotation of the motor a ticket actuating drum is driven by the motor shaft through a uni-directional clutch mechanism for a distance sufficient to eject one ticket from the machine from a. continuous strip of such tickets. On reverse motion of the motor the clutch slips, so that the ticket feeding drum is not actuated. However, on such reverse motion a knife blade actuating arm engages one of a pair of knife blades and drives the knife blades into shearing engagement. The ticket having been fed between the knife blades during the feeding operation on the forward rotation of the motor, is severed. As the moving knife blade reaches its top position it raises the arm of a ratchet type counter, and thereby registers 0r counts the operation. At the same time the moving knife blade actuates one of the contacts which are bridged by the coin in such sense as to separate the, contacts and permit the coin to drop into a receptacle. The moving knife blade is then released, and very rapidly returns to its original position in response to force supplied by a spring, and in so doing. releases the contacts so that they return totheir original position. in response to a bias spring.

Should two coins have been inserted in the coin chute simultaneously, the movement of the contacts will be. sufiiciently rapid to engage the second, of the coins after dropping the first of the coins, so that the contacts will again be bridged and a further cycle of operations will occur. Should no further coin exist in the coin 3 chute the operation of the device will be terminated.

Referring now more specifically to the drawings the reference numeral I identifies an electric motor, which when energized executes forward and reverse motions of predetermined extent in succession until dc-energized. Motors of this character are descirbed in the U. 8. Patents to H. R. Stuart, #1,821,123 issued September 1, 1931 and B. B. Holmes, #l,708,093 issued April 9, 1929. Electric motors of this type are well known in the art and accordingly, the details of the electric motor have not been illustrated and 'are not herein described. The electric motor I is supplied with a shaft 2, provided with a pulley 3. Secured to the pulley 3 is a pulley arm 4 which extends generally radially of the pulley 3, and

4 of the shaft 2, which is clockwise as seen in Figure 2 of the accompanying drawings, the pin I5 rides on the cam surface of the toothed cam I3, while engagement of the arm I9 with a tooth of the cam I8 prevents rotation of the feed drum I2. On forward rotation, which is counter-clockwise as seen in Figure 2 of the drawings, a tooth of the toothed cam I3 engages the pin I5 and drives the feed drum I2, the end of the blocking arm I9 then riding on a cam surface of the locking direction on forward rotation of the motor I.

which is so mounted with respect to the pulley 3 as to be rigid during reverse rotation of the electric motor I, and to be resilient or to give during forward rotation of the'electric motor I. The desired properties of the pulley arm 4 may be accomplished in various known ways, the preferred way being illustrated in Figure 5 of the drawings, and described hereinafter. It is the function of the pulley arm 4, when actuated during reverse rotation of the electric motor I, to raise a movable knife blade 5, which is pivotably mounted on a pin 6, against the counter force exerted by a coil spring I, the knife blade 5 at the top of its stroke as seen in Figure 3, actuating the arm 8 of a conventional counter 9, to insert therein a single digit, and further entering into shearing engagement with a stationary knife blade ID, for cutting a ticket from a ticket roll or strip H. After the moving knife blade 5 has reached the top of its stroke'and accomplished its counter actuating and ticket cutting functions, the pulley arm 4 passes above the end of the knife blade 5 and out of engagement therewith, whereupon the spring 'I very rapidly returns the knife blade 5 to its initial position, as illustrated in Figure 3 of the drawings.

On forward rotation of the electric motor I the pulley arm 4 is driven into contact with the upper edge of the knife blade 5, as seen in Figure 3 of the drawings, and by reason of its resilience is enabled to ride over the knife blade 5, to a position adjacent its underside, as illustrated in Figure 3 of the drawings, in readiness for a ticket cutting operation.

Further secured to the motor shaft 2 is a ticket actuating drum l2, which is driven from the shaft 2 via a one way clutch on forward rotation of the motor- I. The one way clutch comprises a cam I3 which is rigidly secured to the shaft 2, and which rides in an axial aperture l4 provided in the drum I 2. Additionally, the clutch comprises a pin I5, mounted in a radial aperture IS in the drum I 2 and extending into the axial aperture I4 by virtue of pressure exerted by a spring l'l'located behind pin I5 in radial aperture I6. The pin I 5 constitutes a driven member of a one way clutch, which is driven by the toothed, cam it, the latter operating as the driving member of the clutch. 7

A further toothed cam I8 is provided, which is secured to the feed drum I 2 in any convenient fashion, and which cooperates with a resilient blocking lever IS, secured to a pin at one end, and the other end of which rides on the cam I8 during forward rotation of the feed drum I2. The teeth of toothed cam I 8 engage the other end of the lockinglever IS on reverse rotation of the shaft 2. Accordingly, on rearward rota on .The ticket strip I I may be fed from a roll (not illustrated), and there are provided a number of guide rolls 23 and guide pins 24 for guiding the ticket strip to and over the drive drum I2 and thence to an opening in the machine adjacent knife blade III, to which each ticket may be fed, and from which each ticket may be removed after it has been severed.

A coin chute 25 is provided, the side walls 26 of which may b fabricated of plastic or other insulating material, and at the edges of which. may be provided a pair of contacts 21, 28, fabri-- cated of superposed metal sheets, 27 21 and 28 28 respectively which are resilient in nature. The distance between the contacts is such that upon insertion of a coin into the coin chute the coin bridges the contacts 21, 28, completing an electrical circuit (not shown) for the electric motor I. One of the contacts 2'! is normally rigidly secured within the coin chute 25, while the other of the contacts 28, is secured to one arm 29 of a. pivotably mounted bell crank lever 30. which is normally biased by means of a coil spring 3| into its position within the coin chute. The other arm 32 of the bell crank levertil is arranged to be engaged by an end of the moving knife 5, when the latter reaches its uppermost position, thus pivoting the bell crank about its pivot point in such sense that the contact 28 is separated sufliciently from the contact 21 to permit the coin to drop into a suitable receptacle.

It is precisely at this moment that the knife blade arm 5 is released by the pulley arm 5, and moves rapidly down, releasing the bell crank as. The latter then is pivoted in response to its biasing coil spring 3| in such sense that the contact 28 is again thrust toward contact 21. The action takes place with sufficient rapidity that should several coins have been inserted in the coin chute during the ticket issuing and counting operation, one coin will be released by contacts 21, 28, but the next succeeding coin will be trapped thereby,

and accordingly the circuit for the electric motor will be again completed and the latter will then proceed through a further cycle of operations in response to the second coin.

Parallel plates'33 and 34 form supports, for the mechanism of the present invention, between which are mounted the guide rolls 23 and the pins 24 which guide the paper strip II, as well as the feed drum I2 and its associated one way clutch. Extending at right angles from the plate 34, is a bracket 35, to which is secured the pin 6, which supports theknife blades 5 and it, and on which knife blade 5 pivots. Extending outwardly and at right angles to the plate 33 is a further bracket 3B, to which is secured the register or counter 9, and the coin chute 25. The motor shaft 2 extends between the. plates 33 and 314.. the. motor I being; mounted. outsidethe plate: 33.

Reference is made to- Figureb of the accompanying drawings which. illustrates certain details: of the. pulley arm- 4,. which is shownas con.- sisting. of two arm segments, 4a,. 41), one. of which, do, is secured to the pulley 3,. and. the. other of which, 4b. is pivotably mounted on a. pin 31,. extending from segment 4a,. and is urged by means of a coil spring 38 into. colinearity with the. arm segment. 4a.. The arm segment 4c is. provided with a stop. 39. which prevents counter-clockwise rotation of the arm segment. 411 about the pin. 31, Whenthe. arm segment ib is colinear with the. arm segment.- 411. On the other hand clockwise. rotation of the arm segment 41) about the. pin 37 is not prevented, but takes. place against the. bias force exerted by the coil spring 38.. Accordingly, on. forward rotation of the motor. shaft 2,. the arm segments. 4a and 4b rotate counter-clockwise, as seen in. Figure 5, and. when. the arm segment 4?) rests on the upper surface of. the movable knife. 5, the arm segmentllb pivots. about the point 3.! until the arm. segment 41) slips over the top of the movable knife blade 5, and attains a position under the knife blade- On reverse rotation of the motor shaft 2 on the. other hand, the arm segments 4a and 4b. act as a rigid single member, by virtue of the stop 39 which prevents counterclockwise rotation of the arm segment 42) about the pin 31. Accordingly, the arm 4, raises the movable knife blade 5 until such time as the outward. end of the arm segment 41). slips from under the movable knife blade 5, the latter action taking placev by reason of the fact that the end of the arm segment 41). describes an arc of a circle.

Describing now briefly the operationv of the mechanisms and structures above described in detail, one or more coins may be inserted in the coin chute 25, the lowermost of the coins bridging the contacts 21 and 28, which have a normal separation such as to prevent passage of any coin. When the contacts are bridged an electric circult is completed for an electric motor I, which proceeds to execute forward and reverse. rotations of predetermined extent so long as the circuit. is energized. Upon forward rotation of the electric motor 5: a ticket feeding drum i2 is actuated, through a one Way clutch comprising a toothed cam l3 secured to the shaft 2' of the electric motor I and a pin l5 secured to the ticket feeding drum :2, and extending into the path of the teeth of the tooth cam I3. The ticket feeding drumaccordingly feeds a predetermined length of ticket to a cutting station immediately beneath a stationary knife blade II).

On reverse rotation of the electric motor I the one way clutch which drives the ticketfeeding drum [2 in response to forward rotation of the electric: motor I, slips,v so that the. ticket feeding drum [2 remains stationary. Positive means are provided to prevent reverse rotation of drum I2.

The pulley arm. 4, which is located under the movable knife blade 5, raises the movable knife blade 5, on reverse rotation of the electric motor I, until the knife blade 5 reaches shearing engagement with the stationary knife blade I 0 and cuts 01f one ticket. On still further movement of the pulley arm 4 the latter is disengaged from the movable knife arm 5, and the latter, which is spring biased downwardly by means of a coil spring, rapidly returns to its original or unactu, ated condition.

Substantially simultaneously with. the. ticket cutting-operation or slightly thereafter, the .movable knife blade 5 actuatcs the. bell crank. 3ll-,,-on which is mounted one of the. coin holding con.- tacts 28,. and separates the, coin holding contacts 21 and 2B,, permitting the.- coin to fall. into areceptalclev provided for that. purpose. When the movable knife blade 5 is returned to its original position .the bell crank 30 is rapidly returned to its. original or unactuated position in response to bias provided by coil spring 3.1.. This action takes. place with sufilc'ient. rapidityso that should a plurality of coins have been inserted simultaneously in the coin chute 25; one of the coins will be dropped and the contacts 21,. 28 turned to their unactuated or normal position, in time to retain the succeeding coi'mthereby again completing a circuit for the electric motor I, and enforcing, a succeeding cycle of operations of. the machine.

Due to the provision of the superposed, resilient leaf contacts 21 21 ,28 28 ,;on the contact members 21, 28 respectively, it. is insured that the metallic coin closes the motor circuit at. all times. For, as will be apparent from an inspection of Figure 4c of the drawing, the coin when dropped in the chute will be. contacted on each side thereof at two places by the. ends of the resilient leaf contacts. Even if a poor contact exists at one spot-say adjacent member 21 by reason of the presence of rust, etc on the coin, a good electrical contact is. likely to be made at the other spot, .i. e. when the member z'l touch'es the coin. Further, each coin, in descending to a position of rest on contact members 2.1),, 28, is rubbed by the resilient leaf contacts, and thereby tends, to be cleaned, so that a, good electrical contact may be made therewith. I

Primary reliance for establishing a circuit. for the. electric motor I is. placed in contact between the coin and resilient leaf contacts 21 21 2.8 28 and accordingly contact members 21, 28 may or may not be electrically conductive, as. desired. Suitable insulating mountings must. be. utilised (not shown) for insulating the. electrical contacts from thebody of. the machine, or if preferred, the body of the. machine may be. utilized as a ground for the electric motor 1, in. which case only one set of the contacts need be insulatedly mounted, as will be clear to those skilled in the art.

It, will be noted that. utilization. of a. reversing motor, which executes periodic forward and; reverse rotations, or which drives a shaft in predetermined". forward. and reverse rotations, results simplification of apparatus: of the character herein described. The severance of a. ticket, for example. may be. arranged to. take place at any time during reverse rotation. and the release of a coin from the coin chute may likewise take place at any time during reverse rotationfollowing ticket severance and registration or counting. Should a reverse rotation of motor shaft 2 not have been completed when a coin is released this will prove of no importance, since completion will take-place in response to a succeeding coin, and thereafter a further cycle of operations will take place, of ticket feed, registration, ticket severance, and coin release. The timing cycle is, accordingly, by no means critical, and cverrunning of. the electric motor, after its energizing circuit has been broken, of no effect.
