Application January 29, 1953, Serial No. 334,051 12 Claims. (Cl. 101-69) This invention relates to vending machines and more particularly to machines for vending tickets such as are used by railroads.

Objects of this invention are to provide a ticket vending machine which is particularly adapted for issuing tickets such as are used by railroads, which does not need an attendant, which cannot be operated by unauthorized persons, which can be located away from the station, which keeps a record of its transactions, which punches both the record and the ticket for use with punch card equipment, which will issue return trip stubs, which can be adapted for use with reserved or Pullman space, and which advances the art generally.

A ticket machine according to the invention comprises feeding means such as a plurality of rolls for moving Webs of paper or a like sheet material along a pathway past means for impressing or applying selected information, for example, the names of the originating and a selected destination station, upon the webs of paper. Preferably the information impressing means comprises a rotatable drum having a plurality of plates mounted on the inner surface of the drum so that the plates can be brought adjacent the web of paper. Upon the opposite side of the paper from the selected plate is provided solenoid-operated means such as a platen for forcibly bringing the paper into contact with the plate so that the information upon the plate is transferred to the paper either by embossing, by means of an inked ribbon or otherwise. A second set of auxiliary plates is mounted upon the inner surface of the drum adjacent the abovementioned first set of plates. Each auxiliary plate bears return trip information which is correlated with the station information on the first plate of each pair. The selected auxiliary plate is brought into forcible contact with the paper by separately operable solenoid means. The plate also preferably includes punches whereby the web of paper is pierced according to a code for punch card equipment. A slide is provided for inserting in the machine a customers token preferably in the form of a rectangular plate having at least one of its edges notched according to a code so that solenoid means including spring loaded punches will pierce the web of paper in positions corresponding to the code notches.

These and other objects and aspects will be apparent from the following description of a specific embodiment of the invention which refers to drawings, wherein:

The ticket vendor chosen for the purposes of illustration is particularly adapted for installation in business offices and public places such as hotel lobbies or in small stations where it is impractical to maintain a station agent, or in large stations to relieve congestion at the ticket windows. As is shown in Fig. l, the vendor comprises a horizontally disposed rotatable hollow drum 10 which is enclosed in a sheet metal housing 12. The front end of drum is open and is provided with a flange 14 whose periphery is knurled so that the drum, which is journaled in bearings (not shown) can be manually rotated. On the outer surface of the drum are a plurality of name plates, such as 16, each bearing the name of a destination railroad station other than that at which the vendor is located. Rotating ofthe drum 10 selectively causes these name-plates 16 to appear at a window 18 located in the top of the housing 12. A spring biased locking pin 20 is used to index the drum 10 exactly so that a ticket to a destination point corresponding to the name-plate 16 disposed at the window 18 can be printed as described below.

Around the inner surface of the drum 10 are secured a plurality of destination plates 22 each corresponding respectively to one of the name-plates 16. As is best shown in Figs. 2 and 3, each destination plate 22 has embossed thereupon in raised characters 23 names of a destination station and the originating station at which the machine is located. Each destination plate may also carry an insert having raised characters showing the cost of the ticket and tax, and such insert may be replaceable to accommodate changes in rates which may be made from time to. time. Each of the plates 22 also has a plurality of punches 24 located according to code for a punch card machine corresponding to the stations so that a record can be made in the well-known manner for statistical purposes. In the corners of each of the plates .22 are tapered aligning pins 26 for registering with corresponding apertures in a movable platen 28 with a grid of perforations for receiving the punches 24 of the plate 22 that has been located in the adjacent effective position by the rotation of the drum 16 as described above.

The perforated platen 28 is carried upon a yoke 30 "which is connected with the armature of an electromagnet 32 (Fig. 1) so that energization of the electromagnet forces the platen against the destination plate 22 thus causing the punches 24 to pierce the two adjacent webs .of paper Pt and Pr threaded therebetween as will be described below. The embossed characters 23 of the plate 22 simultaneously stamp the names of the stations upon the upper web of paper Pt, for example, by deformation of the paper or by punching holes similar to the characters (not shown) used to cancel a bank check. An inked ribbon may also be used if desired.

Immediately to the rear of the first set of destination plates 22 is a set of corresponding auxiliary return trip plates 34 each ofwhich is similar to the adjacent destination plate except for the legend it bears and the different code arrangement of the punches. The forward edge of the return trip plate 34 is provided with a serrated knife 35 (Fig. 1) for making transverse perforations in the web Pt when a movable platen 36 is brought into token, such as the credit plate T shown in Fig. 5. With the slide in the pushed in" position shown in Fig. 6, the credit plate is immediately above a block 44 which carries a plurality of spring loaded punches 46 in recesses in its upper face. When the punch is moved upwardly by an electromagnet 48 (Fig. l), the particular punches 46, aligned with the slots or notches 49 (Fig. in the opposite longitudinal edges of the credit plate, pass through the paper webs Pt and Pr into aligned apertures in the top paper guide 59. The remaining punches 46 not aligned with the credit plate slots 49 are blocked by the body of the credit plate T so that the paper webs Pt and Pr are punched only with a code corresponding to the slots in the opposite edges of the credit plate. The arrangement of the notches 49 in every credit plate issued is different so that either the ticket formed from the web Ft or the record web Pr can be used in an automatic tabulating machine of the conventional type to charge the ticket to the purchasers account. Carried by the inner face of guide 50 is a switch S1 positioned to be operated by the token T as hereinafter explained.

The webs Pt and Pr then pass over a backing plate 52 and beneath a horizontal extension 54 of the casing which has a slot or window 55 therein so that the operator can sign his name with a grounded electric stylus W (Fig. 7) which forms one recording electrode. The backing plate 52 is insulated from the casing extension 54 to form the other electrode so that a current flows through the paper webs Pt and Pr which are of any of the well-known electrosensitive recording papers that change color to form a permanent record upon the passage of an electric current therethrough. The web Pr then passes around an idler roll 56 to a power driven take-up reel 58 (Fig. 1). The other web Pt passes between two power driven feed rolls 6!) and 62 and out through an aperture 59 in the front edge of the casing, the top edge of which is serrated to permit the ticket to be torn off by the purchaser.

Operation The credit plate T such as is shown in Fig, 5 isinserted in the aperture in the slide 42. In order to prevent old credit plates from being used, the end notches 63 of the credit plate must fit keys in the slide aperture or the plate will strike the top guide 50 preventing the slide 42 from being pushed in all the way. By changing the key arrangement of the slide 42 periodically and at the same time issuing new credit plates a periodic check is maintained whereby old plates (such as are lost or belong to bad credit risks) cannot be used. If a proper up-to-date plate is used and the slide 42 pushed all the way in, as shown in Fig. 6, the actuator of switch s1 is operated to transfer the switch contacts so as to energize the machine. To prevent operation of the switch s1 if the slide 42 is pushed in without a credit plate inserted in the aperture therein, the switch is located to one side of the slide where it will not interfere with the action of the code punches 46, but where the end of the switch actuator arm will contact one edge of the credit plate so that without a credit plate in the slide aperture, theswitch actuator arm is not depressed and the switch contacts are not closed. To prevent juggling of the slide so that the inner end thereof will operate the switch, a longitudinal slot (not shown) is cut in the end of the slide adjacent the switch actuator arm.

As can be seen from the wiring diagram in Fig. 7, the closing of the contacts of the switch s1, as above described, completes a circuit energizing the electromagnets 32 and 48 from the terminals t1 and 12 of a power supply (not shown) so that destination plate 22 and the block 44 impress the punches and characters of the station, price, tax and customer codes, respectively, upon the webs Pt and Pr as has been described above. If the manually operated return trip switch s2, which is located upon the front of the machine, is closed, switch s1 also energizes the clcctromagnet so that the return trip plate 34 also is operated. The operation of switch s1 also energizes the reset solenoid L1 of a stepping relay R to reset the moving contact of the relay to the No. l stationary contact. The relay R is of the type wherein the moving contact is transferred or stepped to a sequential stationary contact each time the actuating solenoid L2 is energized. During the stepping action it is necessary that the circuit made by the movable relay contact with any stationary contact is not broken until after contact is made with the following stationary contact.

After the slide 42 has closed the normally open contacts of the switch s1 to initiate the above described actions, the purchaser uses the stylus W to write his name upon the portion of the paper web Pf which is exposed at the window 55 in the casing extension 51 so that when the ticket is presented to the conductor a comparison can be made by him with the signature impressed upon the web by the credit plate T when the web Pt is forced against the plate by the block 44, thereby affording a check to make certain the person using the plate is the same person to whom it was issued. The signature inscribed by means of the special metal stylus W (shown in Fig. 7) is electrically linked with the terminal 11 so that a recording current flows through the two webs Pt and Pr of paper to the backing plate 52. As mentioned above, the paper of both the webs Pt and Pr is electrosensitive so that the passage of an electric current therethrough causes a chemical action which results in a permanent change in color so that the signature is visible. The circuit of the stylus W also includes the solenoid L3 of a sensitive holding relay which is connected in series therewith so that as soon as the stylus is applied to the paper the relay is energized through a circuit including the terminal t1, the normally open contacts of the switch s1 closed by the insertion of the credit plate T as mentioned above, the stylus W, the backing plate 52, the holding relay solenoid L3 and the contacts of the stepping relay R to the terminal t2.

The energization of the holding relay solenoid L3 closes the contacts s3 to complete a holding circuit in parallel with the stylus W and plate 52 so that the relay does not fall out when the stylus is removed from the paper. The energization of the holding relay solenoid L3 also closes the relay contacts s4 so that the contacts of the slideoperated switch s1 return to their normal position shown in Fig. 6 when the purchaser pulls out the slide 42 to get his credit plate T, whereupon a motor M is energized from the terminals t1 and t2 by a circuit including the normally closed contacts of the switch s1, the relay holding contacts s4 and the No. 1 contact of the stepping relay R. The takeup reel 58 (Fig. 1) for the web of paper Pr, which forms the permanent record of the transactions and which is retained in the apparatus, and also the rolls 60 and 62, which feed the Web of paper Pt through the slot in the front wall of the housing as shown in Fig. 6, are operated by the motor M through a chain drive or other suitable means (not shown).

The motor M also operates a commutator C which every half revolution completes a circuit between the terminals t1 and t2 which includes the switch s1, the holding relay contacts s4, the commutator C and the actuating solenoid L2 of the stepping relay R so that for every half revolution of the motor shaft, the moving contact advances one step until the stationary contact No. 10-

is reached. If the switch s5, which is mechanically linked with switch s2 and whose purpose is described below, is open, the circuit to the motor M is interrupted when the moving contact reaches the stationary contact No. 10 so that the paper feed is stopped. The diameter of the feed rolls 60 and 62 is correlated with the number of relay steps so that when the motor M is stopped, the paper web Pt has been advanced sufficiently so that an amount equal to the length of a one-way ticket extends beyond the housing extension 54 and the purchaser removes it from the remainder web Pt by tearing it offalong the serrated edge which forms the top of the housing slot.

if a return trip ticket is to be urchased, the switch s5 is closed conjointly with the operation of the switch 52 by the mechanical link so as electrically to connect the stationary contacts and 11 in parallel with contacts l to 9 of the stepping relay R so that the motor M makes two additional half revolutions to feed the additional paper required for the return trip stub before the power supply to the motor is interrupted by the movement of the moving contact to the open contact 12. In either case when the stepping relay R opens the energizing circuit of the motor M, it also opens the circuit of the holding relay solenoid L3 so that the relay drops out and the machine is ready to print the next ticket.

The above described vending machine may be adapted for the sale of reserved or Pullman tickets by providing a telephone (not shown) so that the purchaser can call a reservation clerk either by means of a direct telephone line or through the public telephone system. The purchaser gives the clerk the number of the vending machine from which he is calling and the type of accommodation desired. The clerk confirms the reservation verbally. This information is also printed upon the ticket by means of the printing wheels 7t) which are mounted to rotate separately upon a common shaft 71, as is shown in Fig. 8. The periphery of each Wheel bears appropriate numerals or letters so that by the rotating thereof, as described below, an appropriate legend can be impressed upon ticket to identify the train, date, the reservation, and the price of the ticket and tax. Formed integrally with each of the wheels 70 is a gear 72 which engages the teeth of an associated rack 74 so that a punch 76 extending upwardly from one end of the respective racks is moved as the correlated wheel is rotated. The wheels 70 are positioned beneath the paper webs between the electromagnets 32 and 48 (Fig. 1), the axis of the supporting shaft 71 being disposed in the direction of movement of the paper webs so that the punches 76 are moved transversely of the webs as the respective wheels 70 are rotated.

As is shown in Figs. 8 and 10, the mechanism for rotating each of the respective wheels 70 comprises an electromagnet such as the solenoid 78 at the end of whose armature is carried a spring loaded pawl 80 which engages the teeth upon the correlated gear 72 so that each time the solenoid is energized, the corresponding wheel is moved one step to bring the succeeding numeral or letter to the uppermost position on the periphery of the wheel. The rack is conjointly moved so that the punch 76 assumes a relative position transversely of the paper webs corresponding to the uppermost numeral of letter.

The supporting shaft 71 for the wheels 70 and the solenoids '78 are mounted upon a plate 81 (Fig. 10) which is raised by the energization of a solenoid L6 to impress the legend of the Wheels 70 upon the paper webs and conjointly causing the punches 76 to pierce the paper webs thereby to code the ticket for an automatic accounting machine. The paper Webs are preferably backed by a platen 84 having a plurality of perforations 86 therein which are arranged in aligned rows to re, ceive the punches 76.

The above described solenoids '78 are energized by the reservation clerk to position the printing wheels 70 and the punches 76 by means of the control circuit shown in Fig. 9, wherein the normally open contacts s6 are similar to those used in an automatic telephone, being closed any selected number of times by means of a manually rotatable dial. The dial controlled contacts s6 are located in the office of the reservation clerk and electrically interconnected with the remaining circuit elements by means of wires w which may be the telephone line used for calling the clerk.

Each closing of the contacts of the switch s6 by the first operation of the dial by the reservation clerk completes a circuit between the terminals t1 and ll of the 6 power source for operating the vending machine which circuit also includes the first solenoid '78 and the time opening contacts s7 of a time delay relay L4 thereby successively to energize the solenoid a plurality of times corresponding to the selected aperture in the contact operating dial. Each time the solenoid 78 is energized the wheel 79 is advanced one step by the pawl 80 so that by selecting of the dial aperture a corresponding character is positioned by the wheel and punch 76. The first closing of the contacts s6 also completes a circuit through the normally closed contacts s8 of a holding relay L5 energizing the operating solenoid thereof to close a normally open contact s9 before the contacts s8 are opened. The closing of the contacts s9 completes a holding circuit directly linking the relay solenoid with the power supply terminal t1, so that the solenoid remains energized subsequent to the electrical isolation thereof from the dial contacts s6 by the opening of the contacts s8. The operation of the holding relay L5 also closes the normally open contacts s10 to energize the solenoid of the time delay relay L4 from the terminals t1 and t2 start the timing period thereof.

The time delay relay L4 is set to transfer its s7 and s11 after an elapse of a time period which is slightly longer than is required for the closing of the contacts s6 the maximum number of times permitted by one operation of the dial. After the end of such period the contact .57 opens isolating the solenoid 78 and conjointly closes the contacts .911 so that the second operation of the dial closes the contacts s6 causing the second solenoid, which is designated 78 in Fig. 9, to be energized a number of times corresponding to the selected closings of the contacts thus moving the second wheel 70 into the desired position. The holding relay L5 and the time delay relay L4 operate similarly to the relays L5 and L4 as described in detail heretofore so that the solenoid (not shown) controlling the third wheel 76 is energized by third operation of the dial contacts s6. The remaining wheels 70 required to designate the reservation train,

date and other information desired, are operated by similar solenoids and relays of which only the last solenoid 78 and associated relays L4 and L5" are shown (the others being interposed at x), are positioned by successive operations of the dial controlling the contacts s6.

The closing of the contacts 51111 of the last time delay relay L4 energizes the printing solenoid L6 raising the wheels 70 and the punches 76 into contact with the paper webs, the circuit energizing the solenoid being interrupted by the opening of the contacts of a limit switch s12 which is tripped by the supporting plate 81 at the uppermost limit of its travel. Connected in parallel with the solenoid L6 and the switch s12 is the operating solenoid of a time delay relay L7 which after the elapse of a time period suificiently long to complete the printing movement of the wheels 70, closes the relay contacts s13 to energize a resetting solenoid L8 from the power supply terminals t1 and t2.

The armature of the solenoid L8 is connected to one end of a lever 88 (Fig. 7) whose fulcrum is at 96. The other end of the lever is slotted, slidingly to engage the pin 92 extending through one end of a push rod 94. At the other end of the rod 94 is a transverse member 96 which engages the ends of the racks 74 to return them to their original positions when the solenoid L8 is energized as described heretofore. As the transverse member 96 reaches the end of its travel wherein the racks 74 are returned to their original position, the member actuates a switch s14 (Fig. 9) whose normally closed contacts open momentarily to de-energize all the solenoids and relays so that the various switches and contacts return to their original positions.

The device may be adapted to the issue on credit of off line tickets, i. e., tickets covering passage to a destination not a through train of the originating carrier.

For this purpose the passenger calls the clerk at the terminal by use of the telephone hereinbefore described. The clerk thereupon inserts a prepared rectangular disc suitably perforated to actuate a remote controlled printing device of any well known type contained in the machine at the customers position. This printing device actuates and imprints the customers token (which he inserts at the proper point) upon one web of the roll of paper, the date, a serial number and the ticket for the journey in a continuous strip divided into sections for the carrier involved in such order so that the first coupon is at the end first to be detached, and the imprint of the customers token, is at the other end of the strip for a one Way ticket, or in the center in case of a round trip ticket.

The printing device in the machine also reproduces on a tape by perforations or electronic impressions, the record of the ticket sold, similarly divided, so that the charges may be apportioned among the carriers, and for this purpose a clearing house arrangement is recommended.

While I have shown and described desirable embodiments of the invention, it is to be understood that this disclosure is for the purpose of illustration and that various changes and modifications may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
