THOMSON, OF LANSDOWNE, PENNSYLVANIA, ASSIGNOR TO GLOBE TICKET COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA TICKET PRINTING AND ISSUING MACHINE Application filed February 5, 1931. Serial No. 513,505.

This invention relates to a motor driven printing machine of the type in which portions of a strip or web are printed to form tickets, the printing being effected by means of a single rotary type cylinder cooperating with means'whereby the form to be printed may be selected at the will of the operator. The improvements forming the subject matj ter of this application are particularly 1o adapted to the type of machine described in certain Aapplications .filed by Christopher Frederick lVebb, Serial Numbers 260,268, 301,843 and 480,990, filed, respectively, March 9, 1928, August 24, 1928 and September l0, 1930. It will be noted from the following description that the general operation is quite similar to the operations of the machines of these applications, and, in fact, the present machine embodies in identical form many of the features of these machines.

It is one object of the present invention to provide a machine of this general character with improved means whereby but one ticket is issued upon a single depression of a key even though the key be maintained depressed following the completion of a ticket issuing cycle. One specific feature auxiliary to the accomplishment of this object .is an improved arrangement for insuring the completion of any cycle of operation which is initiated.

Another object of the invention relates to an improvement in the strip feeding means whereby positive feed is obtained without sacrifice of ease of insertion of a new strip. An associated object is the pro vision of improved strip severing meansk having actuating means in common with the feeding means.

A further object is the provision of a simple driving arrangement which is positive and still so simple that compactness is obtained.

It is also an object of the invention to provide an arrangement whereby inking of all the operatingA type surfaces takes place prior to their use during any cycle.

Still another object concerns an arrangement whereby the type cylinder may be r0- tated freely of the other mechanisms to facilitate the replacement or cleansing of the type. This arrangement has associated with it means whereby a numbering head may be rendered inactive so ter such idle rotations.

An additional object of the invention relates to an improved switch device whereby the motor may be spun without having the machine perform a complete cycle of operation, this being particularly advantageous in effecting discharge of a ticket in case it is not properly discharged in the normal operating cycle, or in properly distributing ink upon the inking roller after a period of rest. In thepresent machine, it may be pointed out, the inker is driven directly by the motor and not parts which have only cyclical operation.

Other objects of the invention, relating particularly to details of construction will be apparent when the following description 1s read in conjunction with the accompanying drawings, in which:

Fig. 1 is a vertical section of the machine taken approximately on the plane indicated in Fig. 2, the parts being viewed in the direction of the arrows 1-1;

Fig. 2 is a generally vertical section of the machine illustrating certain of the interior parts in front elevation or partially broken away, certain parts being omitted for clearness;

Fig. 3 is a vertical section of the machine taken approximately on the same plane as Fig. 1, the parts being viewed oppositely in the direction of the arrows 3 3;

Fig. 4 is a generally 'horizontal section taken on the surface indicated by the face 4-4 in Fig. l, various parts being omitted for clearness;

Fig. 5 is a front elevation of the mechanism taken interiorly of the face plate of the casing, parts being broken away;

Fig. 6 is a side elevation of the type cylinder, shaft and associated parts;

Fig. 7 is a perspective view of details of construction; and

Fig. 8 is a sectional view of the switch arrangement.

The operating parts of the mechanism are showing details as not to registhrough those enclosed within a casing designated as a unit by 2, the casing bei` provided with a removable top plate and an interior front plate 0. rl`his casing' is adapted to surmount a suitable magazine containing a ticket strip supply of the usual roll or folde-l type, the end of the strip passing upwardly to the mechanism as indicated at S in l. lt will be obvious that the form of the particular using and its relationship to the supply are capable of wide variation and7 so fa' as the operation of the mechanism is concerned, are immaterial.

A motor S furnishes the powe necessary for the operation of the mechanism through suitable reduction gearing 10 which drives a gear 12. The gear 1Q in turn drives the large gear 1-1 carrying the ratchet wheel 1G, thevcdmbination being` journalled upon the main shaft 17 having suitable bezrings in the side plates of the frame. The nose 18 of a pawl Q0, pivoted to a member fixed to the shaft 17 and urgeil by a spring 24 in a clockwise direction viewed in -nig. 1, is adapted to engage within the openings between the teeth of the ratchet wheel. lVhen the parts are in static condition, clockwise movement of the pawl 20 is prevented by its engagement witl the i of arm 20 which at this time is located larrfeeiA a latch Q8 and a projecting portion 30 of the member rlhe type c X/'linder 3Q is `iournalled on the shaft 17 but during ope ati've condition of the mechanism is constrained to rotate therewith by reason of the fact that a slide 3l adjustable radially in member 22 by a screw 36 carries a hook 38 embracing a pin L10 between rubber shock absorbers '-l-Q, the pin and shock absorbers being carried by the type cylinder. From Fig. 2 it will be'clear that turning` of the screw 230, which is rotatably mounted in member and held against radial movement, will serve to move slide 3l radially so that its hook may be disengaged from the pin. As a result the type drinn may be rotated on the shaft independ ntly'iof other parts of the mechanism;

Members -ll carried by the periiihery of tl e cylinder provide dovetailed openi for the reception of replaceable tyr 46 which may be placed in pos tween side tlaiges i8 and then clamped by the mem rllhe type cyli ider carries a 'am drum 50 M ed cams "r2 staggered about which are locat t axially and anguarly uisiosed to corre- .l c spend with the type plates 40. At the ends of the series of ci ms 52 are transverse cams 5l and 50 having axial extents as great as that of the entire series l cams the cams 5l and 50 corresponding angularly respectirelj.' to the the n nnbering head 5S and il i i i e() eating naar, o

rllhe numberin nead 5S is adapted to be actuated upon each operating revolution of the type cylinder so as to successively number the tickets, this being effected by the oscillation of arm (32 by the eccentric strap (il surrounding the eccentric 00 journalled on shaft 17 and arranged to be normally held stationary by the engagement of an arm (3S, pivoted thereto, with a pin 72 lixed to the casing7 the arm being releasably held on the pin by a f-:pring` detent. A pin similar to pin 72 and also associated with a spring detent is carried by the cam drum. lf it is desired to turn the type cylinder for cleaning or replacement of type plates, the arm (38 may be released from pin 7; and engaged with iin 70 so that the eccentric and ty unit, without,

cylinder will turn as therefore, causing actuation of the numbering head.

An inker 7lis pr vided consisting of a well, an inling roller 7G, and suitable transfor rollers carrying inl: from the well for application to the inliing roller. The inlting roller mounted on an axle and is movable upwardly into engagement with the type ein,

surfaces on the type cylinder by arms 78,

slots in w lich receive the ends of the axle. 'lhe arms 7S are carried by a t'ansversc shaft 79 which also carries an arm S0 supporting at its outer end a pin S2 on which slides a roller :am follower Sl. the function of which will be hereafter described. A sp 'ing S0 urge the arm S0 in a counterclockwise direction as viewed in Fig. 17 normally maintaining the roller 70 in lowered position engaging the intermediate tansfer roller and out of the path of the type surfaces. To insure proper distribution of ink the intermediate roller is driven through suitable gearing by the rotation of an arm 88 by engagement with a pin 90 carried by gear 12. The inlier is mounted on a taclt 92 up which it may be slid by an operator into its active position being held therein by a suitable releasable latch. This inker is of the same gene 'al type disclosed in the ll'vebb applications referred to above or illustrated in the application of Horace D. Black, Serial Number 359,989, tiled May 2, 1929.

ln order to produce a positive, accurate of rae tic ze` strip a feed wheel 96 is iro fined, t ie wheel carrying pins 9S for eni hin perforations in the ticket vrip and thereby advancing it along the stai The pin wheel 9G is seo a shaft carrying a pinion 100 meshing with a gear 102 which carries a ratchet wheel 10i and a second holding ratchet wheel 100. A pawl 10S adapted to engage the teeth of the ratchetwheel lOl secured to shaft 17. A lever 110 pivotcd to the frame is provided at one end with a follower engaging a cam 112 on the shaft 17, and at its other end with a detent nose 11-1 adapted to engage within the spaces between the teeth of wheel 106. The follower of lever 1.10 is held in engagement with thecam 112 by a spring 116 which acts on a bar 118 ivoted to a downwardl extending` arm of the lever and passing through plate 6 where it terminates in a button which may be pressed by an operator to free detent 114 from wheel 106 and thereby permit the pin wheel to be freely rotated. This is of advantage when a new strip is to be inserted into the guide 120 since the wheel may then turn to properly engage a pin thereof into a hole in the strip. Upon release of the bar 110, the strip is manually moved until the detent snaps between a pair of teeth, thereby insuring the initial position of the strip so that it is properly located for a subsequent issuing operation. Y

A pivoted knife 122 cooperates with a suitable fixed ledger blade to sever the strip. This knife, which is of the form illustrated in Fig. 4 so that it cuts the strip both ways from the hole outwardly, is engaged by a pivoted lever 123 connected by a link to a bell crank 124. A spring 125 normally holds the bell vcrank to maintain the knife retracted to permit the free passage of the ticket strip, the knife being moved for a cutting movement by engagement of pawl 10S with the forwardly extending arm of the bell crank. It is to be noted that the pawl 108 thus serves for a double function, its normal position being as shown in Fig. 3 from which it will be obvious that it moves the pin wheel at the end of a cycle and operates the knife at the beginning of a succeeding cycle.

Pivotally mounted on a transverse rodfixed in the frame. is a member 126 carrying a continuation of the strip guide above the knife and an impression roller 128 adapted to press the ticket being printed against the type surfaces at the proper times. A curved guide 130 carried by 126 presents the ticket to the ejecting roller 132 driven by the overrun of the motor by a flexible spring belt connection to apulley carried by gear 12. The ejecting roller is carried on a cross shaft 135 and serves to discharge the ticket through a slot in the cover plate 4. l

TheY downwardly extending arm of member 126 carries a pin 136 on which is slidably mounted a roller188. A spring' 140 urges the member 126 in such direction as to bring roller 128 into engagement with stop 141 and to maintain the roller 188 in position to be engaged by cams 54 and 56 and also by one of the cams 52, the particular cam 52 depending upon the position of the roller on the pin 136. The roller is moved along the pin by its engagement y in one bifurcated end of spring element 142, the opposite end of which similarly engages the roller 84. As illustrated best in Fig. 4

yto which is pivoted the element 142 is carried by a slide 144, guided for movement transversely of the machine and carrying a p'in 146 engaged by the forked end of lever 148. This lever is normally urged in a clockwise direction, as viewed in plan, by a spring 150, being thus held in engagement with the end of a lever 152 connected to stirrup 154 journalled on a transverse shaft 156 and having a sloping upper edge 157 (Fig. 5)k engageable by arms 158 also loosely mounted on shaft 156 and held up by springs 159. A key 160 is pivoted to each arm and projects upwardly through the top of the casing so as to be manually depressible by an operator.

The mechanism associated with the keys is best illustrated in Figs. 8 and 7, yto which reference may now be made. Extending across the machine is a fixed bar 161 adapted to be engaged by hook members 162l one of which is pivoted yto each key lever 150. (The members 162 associated with the key levers illustra ed in Figs. 1 and 7 are omitted for clearness.) The hook members are so arranged that when the keys are sufliciently dep'resdy to operate the mechanism they will engage the bar 161, being moved rearwardly by suitable springs, and prevent rise of the key until the end of the cycle of operation.

Jomnalled on the shaft 156, w iich is pivoted in the side walls of the casing, is a stirrnp 168 acted upon by a spring 165 and extending beneath all of the key levers so that as they are rocked by depression of their keys the stirrup will be rocked in a. counter'- clockwise direction, as viewed in Figs. 8 and 7. Carried by the ends of shaft 156 are downwardly extending arms 164 and 164 a clearing stirrup 166 held in normal engagement with bar 161 and just fo ward of, or aligned with, its forward edge by springs 168 and 168 which also serve to urge shaft 156 in a counterclockwise direction. lhen the shaft is free to so move, its motion is limited by engagement of the arm 164 with stop 170. Also ted to arm 164 and controlled by a .ng 171 is a latch 172 having a nose 174 winch, when the machine is not operating, engagesablock 176 fixed to the casing, thereby holding shaft 156 and its associated parts against the action of spring 168.

A tripping member 178 is pivoted to the stirrup 168 and depends' therefrom, being held in engagement with latch 172 by a spring 190, engagement taking` place below a. ledge 180 formed on its rearward edge. Pivoted on the member 178 is an element 182 provided with an end 184 overlapping the ledge 180 and extending somewhat below it whenthe element is held in contact with a stop 188 on the member 178 by a spring 186. The nose 174 of the latch is of suiiicient lateral thickness to engage both 178 and 182.

lt will be noted that the arm 26 is secured to shaft 156 as is also an arm 192 engageable by a cam 19-1 carried by the shaft 17. in resume, the elements 26. 192, 161i, and 161 are fixed to the shaft; elements 152, 154, 158 and 163 and switch blade 2li-l are pivoted thereon for movements relatively thereto. rl"he switch blade 2Ol` is arranged to close the motor circuitby bridging contacts 266, being;` associzrted with elements hereafter described.

As in the macnine illustrated in the applications referred to above, members 196 are utilized to prevent the simultaneous dcpression of two or more keys.

To prevent operation of the machine upon failure of the supply of strip S, a feeler 266 is provided arranged to drop when the end of a strip passes beneath it over roller 198 and permit an arm 202 to move into the path of stirrup 163 and )revent its depre lion.

Records of the number of each kind of tickets issued and also the total munber are kept on suitable counters operated in the followingh manner. An eccentric strap 208 embraces an eccentric 2i() secured to the shaft 17. This strap pivoted at its free end to the stirrup carried by the oscillatory shaft 219. which supports a pin 217 on which are pivoted a number of levers 216, one corresponding' to ch key. Springs 21-1- normally hold these levers so that pins carried by their ends engage within the outer ends of slots in the operating;` levers 218 of the individual counters 220. YV-lhen in this condition, even though the stirrup 212 is rocked during each revolution of the main shaft, the angular movements of arms 218 are insufficient to operate the counters. On the other hand when the levers 216 are depressed by pins 222 on the key bars, the pins move to the inner portions of the slots so that the same movements of stirrup 212 will produce greater angular movements of the arms 218 sufficient to actuate the counters. .#rn arm 226 carried by shaft 213 is link connected to the operating lever of the total counter 22e which is thisoperated upon each revolution of the main shaft.

rlhe parts associated with the switch blade 261 will be clear from l" 8. frs previously stated7 the blade is pivoted on the shaft 156 through the medium of the insulating arm 800. A. spring' 802 reactingr between the arm 800 and stirrup 166 ure-es the arm forwardly against a stop member 36st ried by the arm 164, and extending' laterally. By reason of this connection the switch blade will normally move in unison with the arm 161 and may, so far as the. ordinary c vcle of operation concerned, be considered as integral therewith. The switch blade is, however. movable to close the motor circuit independently of the arm 164 by depression of an eXtra key 306 adapted to rock a lever 308 pivoted on shaft 156 and carrying` an element B10 arranged to contact with the arm 300. bviously if the circuit is closed by depression of key 806, the release of the key will eilect opening; of the circuit since the blade will be moved to normal position by spring 802.

rl`he preceding' description of the machine will make clear the operations of the sevu'al `groups ol' elements. There will now be described the general operation of the machine with particular reference to the relative timing of the operating; parts and those functions of certain parts which are not obvious upon casual inspection.

In all of the 'arious figures the parts are illustrated in those positions which are assumed when the machine is prepared to issue a ticket upon the depression of a key by an operator. Upon the normal downstroke of any key, various events occur in such rapid succession to occur almost simultaneously. The key lever 158 engages the stirrup 163 rocking it about the shaft 156 and thereb'f,Y causing 178 to move downwardly. As this occurs end 184 of member 182 engages nose 174 of latch 172 and yields upwardly against the tension of the liaht spring' 186. which is insuiicient to disenge the latch. unt" the ledge 18() engages I'e latch moving it until its nose clears ock 176. At this time the action of the ectinel mechanism has been completed, the Am 158 havin;` engaged the sloping eda'e o7 of stirrup 154; and having' thereby moved the forked member 1 l2 to carry rollers 81 and 186 into the path of the cam correspending` to the depressed key. The selecl rion is effected by the degree of movement of the lever 158 following' its engagement with stirrup 154. Since the strokes Vof the levers are the same but their contacts with the stnrup are delayed for varying periods due to slopingr eda'e 157, it is obvious that the movement of the stirrup and therefore those of the cam following' rollers will be variable dependiim` on the key selected.

As soon as the nose 171 disengaged from block 176.v the spring 168 acts to rock shaft- 156 producing; the simultaneous occurrence of several operations` The clearing' stirrup 166 moves rearwardly below bar 161 permittina` the hook 162 `:arrid by the depressed lever 158 to swing so as to engage the under side of the bar whereby the key is prevented from risingr until the end of the cycle and the cam following: rollers 84 and are retained in their adjusted positions.

As the nose 17 et moves beneath the block 176. the member 182 drops into engagement with the stop 188 whereby its end 184e will lie below the under surface of the block. T he usefulness of this action will be brought out later and is here mentioned only because of its occurrence in the sequence of operations now under discussion.

llVhen the shaft rocks, member 26 is disengaged from lever 20 and also from the ledge 30 on member 22. The shaft 17 is thus freed to rotate and pawl 18 will engage between the teeth of member 16. The type cylinder is unbalanced so that it will tend of its own weight to rotate in the direction of the arrow in F ig. 1. Since the gear 14 will generally stop so that nok opening of the wheel 16 is opposite the pawl 18, there will generally occur some angular` movement of the type cylinder and shaft 17 prior to the time when pawl 18 engages. Vhen the shaft 156 rocks it also closes the circuit through the driving motor which of course reqrires some small interval to gain speed. However the shaft 17 is already moving when it is picked up by the motor, and its unbalanced condition aids the motor, so that full motor speed is attained in a minimum of time and maintained through the cycle with a resultant considerable reduction in the time required for the completion of a ticket issuing operation as compared with the time which would be required if the design were such that the motor was obliged to start under load.

By the movement of shaft 156, the arm 192 is located in position for later engagement by cam 144.

Owing to the various events just described, the type cylinder is set into operation for the issuance of a ticket. Up to this time the knife 122 has remained retracted and above its path there projects a length of ticket strip equal to that of the desired ticket, one of the perforations in the strip lying directly in the path of the knife. The. cam 108 (F ig. 8) momentarily engages and then disengages the lever 124 producing a cutting movement of the knife to sever a ticket followed by its retraction by spring 125 to inactive position 'clearing the path of feed of the strip.

At approximately the time severing takes place, the cam 54 will engage the roller 84 thereby raising inking roller 76 into engagement with the moving type on the numbering head 58 to freshly ink the same. As soon as the nlnnbering head passes the inker, the roller 84 drops olf the cam whereupon roller 76 again drops to receive further ink from the transfer roller.

Rotation now continues bringing the numbei-ing head opposite the impression roller 128. Vhen this position is approached., the cam 54 will engage roller 138 throwing the impression roller forwardly to press the ticket against the numbering head so that printing takes place, the ticket being fed a determined distance by the type on the head. The roller 138 will ride off cam 54 immediately after this event so that spring 140 may retract the impression roller.

The cani 54 extends laterally so as to engage the rollers 84 and 138 in all their possible positions of adjustment and accordingly numbering of every issued ticket occurs. On the other hand these rollers are engaged by only one of the cams 54 so that inking of and printing by only one of the yplates 46 will occur in any cycle, the plate being determined by the selected position of the rollers. The inking and printing take place in the same fashions as described above in connection with the numbering head so that these operations need not be repeated. The ticket is fed, of course, a relatively greater distance.

similar series of events occur in connection with the dating head 60, the corresponding cam being 56 which, like 54, engages the following rollers in all positions so that every ticket is dated. The feed in this case is suiiicient to carry the ticket into engagement with ejection roller 132 which, being driven by the overrun of the motor, serves to snap the ticket out through the slot in the cover plate.

As the end of the cycle approaches, the cam 112 acts on lever 110 causing it rto free the wheels 106 and 104 and gear 102 which Amove as a unit. Immediately thereafter the pawl 108 engages a tooth of ratchet wheel 104 vmoving it to thereby feed the strip the length of one ticket. The lever 110 is released prior to the end ofthe desired movement of the wheels so that its nose may snap into a notch holding the wheels, and thereby the pin wheel 96, in a definite position. This position is defined by the location of 'a hole in the strip in alignment with the knife.

After this feeding action takes place cam 144 engages armr192 thereby rocking shaft 156 in a clockwise direction as viewed in Figs. 3 and 7. The switch is `thereby opened cutting off the supply of current to the motor. The inertia of the parts, however, produces a completion of the cycle. As the shaft rocks, the nose of member 26 is brought into the path of latch 28, lever 20 and ledge 30. It iirst cams the latch inwardly, is then engaged by the lever 20 to thereby disengage the clutch, and is last engaged by the ledge 30 to positively stop `the type cylinder. The latch 28 then snaps beneath it to prevent rebound and also to assist in maintaining the type cylinder against rotation in either direction.

It is to be noted than when the machine finally approaches its position of rest the cam 194 disengages lever 192. However' reversal of movement of shaft 156 is prevented by the latching of nose 174 with block 176, so that the member 26 will retain the position it has assumed.

by the chosen plate y If the operator has relieved the depressed key of pressure, it will rise under the action of its spring 159 as soon as the stirrup 166 clears the hook 162 from bar 161. On the other hand, even though the operator does continue to press the key, the machine will not be kept from stopping. In such case, the nose 174 engages end 18st of member 182 rocking element 178 outwardly against the tension of spring 190. Furthermore the machine cannot again be set into operation unless the key is permitted to rise suiciently so that the end 184: is above the nose 174i thereby permitting element 17 8 to again swing in .f'ardly. The parts are so designed that extensive movement of the keys must take piace thereby preventing the accidental issue of more than one ticket.

As the key rises, stirrup 15st is disengaged so that the rollers 84 and 188 may be returned to their initial positions by spring 150.

During the rotation of shaft 17, and subsequent to its printing operation, the numbering head 58 is advanced one unit by the travel of strap 6-1 about the cam 66 which held stationary by engagement of arm 68 with the tiXed pin 72. The counter 224 and that counter 220 corresponding to the depressed key are also actuated during the cycle by the rocking of stirrup Q12 by eccentric Q10.

Since the discharge roller 132 is operated directly by t-he motor, if it should fail for any reason to eject a ticket at the end of a cycle it may be rotated by depression of key 306 whereupon the motor will operate without effecting rotation of the type cylinder or otherwise disturbing any of the control elements from their stat-ic positions. This independent operation of the motor is also useful in that the inking rollers may be rotated prior to operation of the machine after a period of activity to thereby insure proper distribution of ink for the printing of the iirstticket. The key 306 may also be used as a testing key to determine whether the motor is operating properly.

The accomplishment of the various objects set forth above will be clear from the foregoing description. It will be apparent to those skilled in the art that numerous variations in details of the invention may be made without departure from the spirit thereof as defined in the following claims.
