10 Claims.

This invention relates to a ticket issuing ma? chine designed to issue one or more tickets in a single cycle of operation.

It is the object of the invention to provide a gether by springs after some tripping operations.

Where anything of this sort is involved, the machine is necessarily noisy. In accordance with the present invention any spring.actuation of parts in this fashion is avoided with only a few exceptions, even in the case of which the engagement of the parts is ofa cushioned character so that noise is avoided.

'Rapidity of operation is achieved by causing the issue of tickets to occurin the first half of a cycle of operation, which cycle is determined by a single revolution of a main shaft controlling all of the parts.

The above and subsidiary objects of the inven-. tion will be apparent from the following'description read in conjunction with the accompanying drawings, in which:

Fig. 1 is a vertical section taken through the apparatus adjacent the left-hand side thereof and showingthe major operating parts, which are located closely adjacent one of the side plates;

Fig. 2 is a similar section but taken further to the right than Fig. 1 and showing the parts to the right of an intermediate supporting plate;

Fig. 3 is a substantially vertical section taken onthe surface, a trace of which is indicated at 3-3 in Fig. 1; and

Fig. 4 is a fragmentary sectional view showing the switch construction.

The machine unit comprises a pair of side.

plates 2-.-2 suitably connected by cross members in a general fashion common to this art. A plurality of units are intended to be arranged side by sidev within a casing (as indicated in Fig. 3) to issue tickets of various denominations. Between the side plates there is located an intermediate supporting plate 4 which carries or aids in the support vof various operating elements. Suitable guiding means for the ticket strip are provided, including members 5 forming a channel approaching the feeding pinwheel and a fixed member I and movable member 9 adjacent the pinwheel designed to maintain the ticket strip in engagement with thepins and lead it past the severing knives. The details of the frame arrangement are of minor importance, and being substantially conventional, need ,not be described in detail.

Extending across the various units so as to be common to all of them, there is a shaft 6 carrying a' number of pinion-s 8 equal to the assembled units. The shaft 6 is driven through a suitable reduction means, either gearing or belting, from a motor which is carried by the housing for the units. Each of the pinions 8 engages a gear ID in the corresponding unit and through such engagement effects the drive of the unit.

The gear I!) is journalled on a pin H extending between the side plates 2 and has securedto it a toothed clutch member indicated at' l2.-. The teeth of the member l2 are designed to engage the laterally turned end Id of a bell crank l6 which is pivoted at I'll upon a cam member H4 and urged in a counter-clockwise direction as viewed in the figures by a spring I8 to bring its turned end M into the path of the teeth of the member l2. When the machine is in its stationary condition illustrated in the figures, a pin 20 on one of the arms of the lever I6 is engaged with the end of a lever 22 having a nose 2% under which there is engaged the end of a latching lever '26 pivoted upon a pin 28 extending between the side frame members. The lever 26 is provided with a cam following extension indicated at 30. The units may be individually locked by means of a lever 32 which, when in the position indicated in Fig. 2, will prevent counter-clockwise move- -ment of the latching lever 26 and hence will prevent any engagement of the clutch. The lever 32, however, may be thrown to a counter-clockwise position in which it clears the lever 26 so that the unit may be operated.

The latching lever 26 carries an arm 34 which underlies a plate 36pivoted in the frame at one side as indicated in Fig. 3. Above the plate 36 and guided through slots in various frame members there are a plurality of key rods, one of which is indicated in the drawings at 38. The others are of similar type, being suitably offset at their upper ends to provide any desired arrangement of the keys. In all cases these keys are constrained to move vertically in contact with the right-hand arm of a U-shaped member 64.

Each of the key rods is provided with an opening 40 through which therenormally projects an ear 42 formed on a corresponding selector mem -ber 44. Assuming that five tickets are to be issued as the maximum in a cycle of operation, there willhe flvekey rods and five selector members 4E pivoted upon the pin 46 and individually urged in a counter-clockwise direction as viewed in Fig. 3 by springs 68. Each of the selector members is provided with a camming projection 50 designed to be projected through a corresponding' slot 52 in the left-hand arm of the U-shaped member 54, which is spaced from the left-hand side plate 2 to provide a channel 56. When any of the keys is operated by being depressed, its engagement with the car t; of the corresponding selector member 84 will rock that selector member in a clockwise direction, projecting the camming' projection 50 across the channel 56. After this action occurs, the key will be moved further downwardly and a solid portion of the key bar will be opposite the ear 42, effectively locking the selector member 5 3 in its new position. It will accordingly retain such position until the key is raised.

Returning now to the drive, there is secured to the cam M 3 an eccentric 58 which operates within an elongated slot in a yoke Sb pivoted at 62 to the left-hand side plate. The yoke at its upper end is connected by a link Ed witha pin $6 which is guided for rectilinear movements within a slot 68 formed in the left-hand side plate. Pivoted on the pin 66 is a bar it which is provided with a bevelled forward end it? designed to engage and ride up the camrning projection Sid of any of the selecting members which happens to be in its clockwise position due to key actuation. The bar Ill carries a roller M arranged to be engaged by a lever 86 along the upper edge of which it may roll. A spring l8 urgesv the lever it in a.counter-clockwise -direction about its pivot l1 so as to initially bring a nose 80 thereof within'one of a series of slots (in the present case five) in a member 82 which is pivoted upon a pin 8 and which is secured to a pinwheel 85 having five pins 88 arranged to engage perforations in a ticket strip to advance the same in the delivery operation. A pinion 90 also secured to the pinwheel and member 82 meshes with a gear 92 pivoted upon a pin 84 and carrying a toothed member 96 designed to be engaged by a nose I04 of a detent member I02 pivoted at I08 to the frame and urged in a counter-clockwise direction by a spring I06.

The detent'member I02 carries a cam following roller 0 arranged to ride upon and be actuated by a cam II2 secured to the cam H4. The bar 10 is provided with a-series of teeth 98 designed to engage the teeth of the pinion 96. The bar I0 is' normally held, when the machine is stationary, in the position illustrated so that,

upon lengthwise movement of the bar it, the teeth 98 would clear the teeth of the pinion 96.

A conventional counter (not shown) may be driven by the gear I00 connected to-thepinwheel 86 in order to indicate the number oftickets issued.

The cam H4 to which reference has been heretofore made is designed to act on thepair of follower rollers H6 and 8 carried by a lever' plate I38 underlying the-arm 34. Each of these the right-hand side plate an ear Mil. In the case of the left-hand unit the ear Mil overlaps the plate I36 of the unit to its right (see Fig. 3) and so on until, in the case of the most right-hand unit, the ear I40 overlaps a pin M2 controlling a switch within a housing M4. The pin is urged upwardly by a spring shown at H86 eflective to hold contacts I41 away from contacts I49 when no unit is operating and thus open the motor circuit. When the pin M2 is lowered by depression of the plate 036, the switch is closed and actuates the motor, serving to drive the assembled units. overlapping of the successive plates l36 by the ears Md the depression of a key in any of a series of assembled units will effect closure of the switch and starting of the driving motor. A lever M8 pivoted on the same pin 23 as carries the lever 25 is provided with an end 3559 designed to engage a tail portion of the plate E35 for the purpose hereafter described. The lever I48 is provided with a follower extension 552 arranged to be engaged by the cam iii. The cam M2 performs a triple function, acting upon the roller H0 and the follower ends 333 and H52 of the respective levers 26 and M8. I

Assuming that a.single ticket is to be issued, the operator will depress the most forwardkey, which is the one shown in the figures. This will rock its' corresponding selector member M to cause the projection 5b thereof to extend across the channel 56. The depression of the key beyond the position causing the opening :30 to clear the car 42 will lock the selector member in such position to cause. it to resist a mechanical thrust to whichit is later subjected. The depression of the key will also depress the arm 35, causing the latching lever 22% to move out from beneath the end of the lever 2 5 and thus release the pin 2% on the clutch lever it. As aresult, the end M of this lever will be moved into the path of the teeth of the member l2 by the action of the spring I8. The parts are arranged so that during the action just mentioned the movements of the elements are obtained without a snapping action so that noise is avoided.

As the arm 34 moves downwardly, it depresses the plate I36 to bring its tail above the lever end H50 and either directly or through intermediate plates I36 closes the switch I by depressing the pin I42 against the action of spring I46, which is a light spring incapable of moving the key upwardly because of the substantial friction It will be obvious that due to the V involved due to the pressure of the selector member v 44 upon it because of the action of its spring 48. The parts so far moved, therefore, unless additional pressure is applied, will retain the positions indicated. Upward movement is further resisted by the fact that the end of the latch lever 26 will now lie to the left of the nose 24 oflever 22, which will prevent its clockwise movement until substantial force is applied.

The motor will now drive the shaft 6 and consequently the clutch l2, imparting counterclockwise rotary movement, to the cams H2 and H4 and the eccentric 58. The cam II2 immediately acts upon the roller 0 to withdraw the projection I84 of the detent lever I02 from between the teeth of the pinion '00, thereby releasing this pinion for movement. The eccentric 58 also begins the counter-clockwise movement of I the yoke 88, thereby driving the bar 10 toward the left. During the initial portion of such movement, the rack teeth 88 are held out of position to engage the teeth of thepinion 86. The movement just described takes place without engagement of the rack and pinion until the bevelled end I2 of the bar I engages .the projection 50 of the selector member 44 which has been actuated. The left-hand end of the bar is then cammed upwardly and the bar is caused to swing about its pivot pin 66, which is being guided within the slot 68, with the result that the roller ll will force downwardly the lever I6, disengaging its end 80 from the slot in the member 82 into which it projected. At the same time the rack '98 is moved downwardly to engage the teeth of the pinion 98. The downward movement of the end 80 releases the pinwheel 86 and the parts geared thereto, including the pinion 96, so that the rack during the further leftward movement of the bar I0 will drive the pinion and rotate the pinwheel 88 to feed the ticket strip. In the case just described, when a single ticket is issued the left-hand movement of the bar continues only sufliciently to move the pinwheel through a peripheral extent corresponding to the length of a determined by the delay before the rack engages the pinion, which delay is determined by the position of the selector member which has been actuated, If five tickets are to be issued, for example, the rack is engaged with the pinion almost immediately after the forward movement of the bar I0 begins, while intermediate numbers of tickets involve suitable delays prior to the engagement. In any event, the total number of tickets to be issued will be projected past the knives I30 and I32 during the left-hand movement of the bar I0.

Adjacent the left-hand dead center pos tion a substantial rotation of the eccentric 58 will take place without any appreciable movement of the bar I0 when lost motion is considered. During this periodthe cam H2 will'engage successivelv the follower ends I52 and 30 of the levers I48 and 26. Engagement with the first causes the projection I50 to engage below the tail of the plate I36 so as to prevent its rising even though the arm '34 is raised, thus maintaining the switch closed and the motor operating. The cam II2 engaging the follower end 30 of lever 26 will cause arm 34 to be forcibly raised. moving the plate 36 upwardly .and raising the depressed key bar and permitting the selector member 44 to again assume its counter-clockwise position with the ear 42 projecting through the hole 40.- .As a consequence of this action, the forward end of the bar I0 is released by the.projecti on 50 of the selector member 44. /This action preferably occurs just prior to the dead center position of the eccentric 58, and in order to avoid noise and eifect also accurate positioning of the pinwheel,

there is prevented the immediate upward movement of the bar I0 by reason of the fact that the projection 80 of the lever I6 is riding upon the periphery of the member 82 and consequent- 1y will not. raise the bar I0 immediately. However, as soon as sufficient further movement takes place to bring one of the notches in the member 82 adjacent the projection 80,.the projection will fall into such notch and the bar I0 will be rocked counter-clockwise under the action of the lever 16, disengaging the teeth 90 from .the pinion 96.

After this occurs, the roller 0 is released by the cam H2 and the pinion 96 is locked in fixed position by the detent I02. The detent I02 is provided so that the cam action between I04 and the teeth 96 may accurately align the ticket strip to bring the portion to be out into alignment with.

the knives.

The clockwise movement of the lever 26 may take place because of the fact that its end applies a thrust to the end 24 of the lever 22 in a direction laterally of the pivot of lever 22, which is thereby caused to be rocked clockwise against the action of its spring to bring its lower end into the path of the pin 20 on the clutch lever 66 to ultimately disengage the clutch and stop the operation.

The reverse movement of the bar I0 now occurs. The rack teeth 90 move rearwardly, clearing the pinion 96. During this reverse movement the cam H4 acts upon the rollers H6 and I I8 toimpart first a cutting movement to the knife I and then a retracting movement to clear a passage for the next advance of the ticket strip, It will be seen that when a purality of tickets is issued the cutting will take place at the end of the series, so that the plurality will be issued in a single strip. As the end of the cycle of rotation is reached, the levers 25 and I48 are released by the cam I I2. The release of the lever 26 merely permits it to be later rocked by a key actuation. The release of the lever I48 withdraws the projection I50 from beneath the plate I36 so that the spring I46 can lift this plate I36 and .the associated plates and also open the motor circuit. At the same time the pin 20 will be engaged by the lower end of the lever 22, causing the end I4 of the lever I6 to rock out of the path of the teeth of the clutch member I2. The engagement of the pin 20 with the end of the lever 22 determines the initial position of the parts. 7
