14 Claims. (01. 164+ v This invention relates to improvements in ticket issuing machines of the type in which one or more tickets are selectively issued and cut from a strip of tickets.

Mechanically controlled machines are commercially available. An example of a mechanically controlled ticket issuing machine is found in U. S. Patent 2,321, which issued to Carl Dodegge on June 8, 1943. The machine disclosed in the Dodegge patent will issue a selected number of tickets, will cut the issued tickets from the strip, will operate throughout only one cycle in the absence of a subsequent selection, and will not operate in the event of a discontinuity in the strip of tickets. These operational steps and controls require a complicated mechanical system, which is expensive to make and to service. Moreover, the mechanical elements are apt to jam or to operate sluggishly and are subject to wear.

An object of the present invention i to provide an improved strip ticket issuing machine in which the operational steps are controlled mainly by electromagnetic means. Another object is to provide an improved ticket issuing machime in which selector buttons are arranged to apply electric power to selector magnets and in which the selector magnets control-stops for disconnecting the driving motor from the power supply. Another object is to provide a"strip ticket issuing machine in which discontinuities in the ticket supply operate a microswitch'which disconnects the power supply. An additional object is to provide an improved strip ticket issuing machine in which the issued tickets are severed from the strip by means of a knife controlled by electric means. A further object is to provide an improved strip ticket issuing machine in which electrical controls are-used to stop and to start the machine and to limit the operation-to a single cycle after each selector operation. i g

Theinvention will be described by referring to the accompanying drawings in which Figure 1 is an elevational view of the ticket issuing machine of theinvention; Figure 2 is a view partly in sectiontaken along the line II-II; Figure 3 is a sectional viewof the magnetically'controlled stops taken along the line-III-III; Figure 4 is a sectional view of the ticket guide taken along the line IV IV; Figure 5 is a sectional view of the sele'ctor'solenoids and their "supporting. plate taken along the lineV-V;'Figures 6 and 7 are views of the ticket severing means; and Figure 8 is a schematic wirstrip ticket issuing,

* includes a ticket feed tioned within the feed wheel tion to the plate Referring to Figs. 1 and 2, the ticket issuing mechanism of the invention is housed within a case Ill which includes a door I I through which the ticket magazine I2 may be inserted and the mechanism may be serviced. The mechanism wheel l3. The feed wheel I3 is provided with projections M which engage apertures in the strip of tickets IS. The ticket strip is guided along the feed wheel by a guide member H3 in which the slot l1 provides clear ance for the projections I 4. The guide member may be supported by a suitable bracket IS. The strips of tickets are fed to an issuing guide IS, an electrically controlled knife or severing means 20, and a trap door 2|, all hereinafter described.

The feed wheel I 3 is mounted on a shaft 22 which is journaled in bearings 23. The feed wheel I3 is driven by a motor 24. The motor is coupled by suitable means to a shaft 25, and througha worm gear 26 and pinion gear 2'! to the ticket feed wheel. The worm and pinion gear arrange? ment is irreversible so that a pull on the ticket strip I5 will not turn the feed wheel.

As shown in Figs. 1 and 3, netically controlled stops 28 are slidably posiand preferably, although not necessarily, so that the axes of the stops are parallel to the axis of the wheel. A locking means may be provided for the stops. The locking means may consist of a recessed portion 29 which provides shoulders. When the stops are at the extreme left or right; the shoulders engage the end of a screw 30 which may also secure the ticket engaging projections I 4. To prevent displacement due to vibration, a small sprin 3! may be arranged to engage the feed wheel. l l

e The ticket strip [5 is fed through the issuing guide l9, through the aperture 32 in the plate 33 in the ticket severing mechanism (see Figs. 6 and 7), and through the aperture 34 in the ticket severing knife 35. The strip I5 is finally pushed through the trap door 2| in the top of the case I 0. The severing mechanism consists, in addi- 33 and knife 35, of a solenoid 36 and biasing spring 31.- The severing knife is held in position and is guided by a slot 38 and rivet severing force i obtained from the biasing spr1ng.- The force is stored by the solenoid acting on the magnetic core 40, and the force is released when the energy in the sole- .noid is released.

Stop actuating solenoids 4|, 42, 43, flgarerespectively arranged on one-side of the feed wheel a plurality of magare diagrammatically illustrated in Fig. 8.

2 l3 opposite successive stops 28. The solenoids are disposed on a plate 45. A starting solenoid 46 is mounted'on a plate 41 on the opposite side of the feed wheel. The starting solenoid is arranged to retract the magnetic core which has engaged a motor control switch 48 and a selector cycle control switch 48a. The motor and selector control witches 48 and 48a may be mounted on the plate 45 which supports the stop actuating solenoids. If desired, a counter 49 may be arranged to engage pins 50 on the feed wheel to count the tickets as they are issued.

If the tickets are to issued, it is desirable to provide means, such as a microswitch 5|, for interrupting the operation of the microswitch in the event of a discontinuity be counted as they are in the ticket strip. The'microswitchoperating member may be made to bear upon the ticket strip, which may be backed by studs or rollers 52. In the event of abreak in'the. strip, the microswitch operating member will be released, thereby opening the switch and the power cir cult.

In the foregoing description, no attempt. has been made to include the electrical circuits, which In Fig. 8, a suitable power source 53 is connected to the microswitch 5t so that, in the absence of a supply of tickets, the power source is disconnected, One branch of the power source is connected by a pair of leads 54 through the. stop switch 48 to the motor 24 and the knife operating solenoid 3B. The push buttons l, 2, 3 and 4 are respectively connected to the selector control switch 48a and to the stop actuating solenoids 4|, 42, 43 and 44, and through the starting solenoid to the power source, thus forming the second branch-of the electrical circuit. The switches l, 2, etc., are provided with a switch interlock 55, represented by dash lines, and illustrated in U. S. Patent 2,235,768, which issued to D. G. (3. Luck on March 18, 1941. While the switch interlock'may be omitted, it is preferable to include an interlock so that an operator can actuate but one It is also desirable to provide impulse type switches which form a single, short contact when actuated. One suitable switch mechanism is illustrated in U. S. Patent 1,927,761, which issued to G. Tauschek on September 19, 1933.

The mode of operation of the device is as follows: If the operator wishes to issue four tickets, switch 4 is actuated. The actuation of switch 4 applies power simultaneously to solenoids 44 Solenoid 44 will attract the magnetic core stop 28, which will be projected to the left as shown in Fig. 2. At the same time, solenoid 45 will attract the magnetic core 28 which has opened the switch 48 and has closed the selector control switch 48a. As the switch operated core is retracted to the right, switch 48 will complete the {power circuit to the motor 24 and to the knife operating solenoid 35 and will open the selector control switch 48a to limit the operation to a single cycle. The motor will immediately start to rotate, thereby driving the ticket wheel l3 in a clockwise direction, as shown in Fig. I.

As the motor is energized, the solenoid 36 is also energized, t-lereby actuating the magnetic core 45, and hence the severing knife 35. As the knife is moved toward the right, the biasing spring 31 is compressed and the aperture 32 is opened. Ihe strip of tickets 15 then issues through the aperture 32 and through: the trap 1 cycle may issue door 2| until four tickets have been issued. At that time the stop 28 reaches the switch 48, which is thereby opened, shutting oil the motor 24. At the same time, power is removed from the knife operating solenoid whereby the biasing spring 31 urges the ticket severing knife toward the left, thus severing the issued ticketsfrom the ticket'strip. At the instant the stop switch 48 is opened, the selector control switch 48a is closed, so that the machine has completed one cycle and is ready to begin another. The next from one to four tickets, depending upon the switch I, 2, etc., actuated by the operator.

Thus the invention has been described as a ticket issuing machine in which a predetermined number of strip tickets may be issued selectively. The mechanism includes a ticket feed wheel which is controlled by electrical means. The controlling means include a series of stops which are actuated by solenoids. An additional solenoid is used to actuate the ticket severing knife. An electrical control disconnects the power supply in the event of a discontinuity in the supply of tickets. Another electrical control limits the operation to single cycles. The relative timing of the several operational steps may be controlled by the relative positions of the solenoids or by relative adjustment of the time constants of the electrical controls. In a similar manner, the length of engagement between the stop 28 and the stop switch 48 may be increased if the motor shows a tendency to coast past the stop position.
