NUMBERING MECHANISM FOR TICKET-PRINTING MACHINES.

Application filed. June 4, 1924.

To all whom it may concern:

Be it known that we, JOHN ALWYN KEL- LER, a resident of Bay Shore, in the county 01 Suitolk and State of New York, and Crmrrns S1.LEL]\IANN, a resident of Richmond Hill, in the county of Queens and State of New York, both citizens of the United States, have invented certain new and useful Improvements in Numbering Mechanisms for 'licket-Printing Machines, of which the following is a specification.

This invention relates to numbering mech anisms for ticket-printing machines, and it has particular relation to an improved mechanism for imprinting successive numbers upon the respective successive ticket units of a continuous ticket-strip as the latter is fed through the machine, the mechanism being operatively adapted to automatically adjust the imprinting numbers in successive order at certain steps during the continuous operation of the machine, whereby the successive identifying numerical data is imprinted without manual adjustment.

The improved mechanism is adapted for use not only in printing successive numbers upon the ticket units of a continuous ticketstrip, such as clothing tickets which are to be attached to garments or other analogous ticket-units for various purposes, but also for imprinting successive numbers in any adapted variable circumstances and requirements for use.

The object of our invention is to provide an improved mechanism of the character set forth, which will possess advantages in point of convenience, positive automatic action, simplicity of construction, effectiveness and general efficiency.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring to the drawings, 14 designates a suitable frame-work for carrying the operating mechanism. A main revoluble shaft, 15, has its hearing, as at 16, in said frame, and is mounted in projective position therefrom and adapted to be operated by any suitable power connection. Said shaft carries a hub or collar. 17, fixed thereto, preterably by a set-screw, as at 18, and at its outer end said hub is provided with a circun'iferential flange forming an end disc. 19, preferably constituted by a circular disc plate secured against the end of the hub 17 by screws, as at 20, and having a central opening corresponding to the bore of the hub.

21 designates an outer disc plate having a central opening or bore by which it is mounted upon the main shaft 15. This outer disc-plate constitutes the main typewheel, and together with the hub-disc 19 forms a boxing within which the supplementary general printing and control mechanism is operatively mounted and carried between said discs 21 and 19. Said discs are locked in fixed connection, and the locked connection is preferably afforded by set-screws, asv at 22, entering from the pe-- riphery of the hub-disc 19 and engaging the ends of stationary stub-shafts, 23, projecting from the inner face of the outer disc 21 into corresponding opening in the hub-disc 19, the discs 19 and 21 being thus in fixed connection with an intervening space, as at 24.

The stationary stub-shafts 23, carried by the outer type-disc 21, are equi-distantly arranged in circular series concentric to the axis of the main revoluble shaft and disc 21 which moves therewith, and in the numercial arrangement of the imprinting I type-numbers as comprised in the improved mechanism as herein shown in the presentembodiment of the invention ten of such stub-shafts are provided. The periphery of the main type-disc 21 is provided with a circumferential series of equi-distant'typenumbers, as at 25, which series, in said present numerical arrangement, runs consecutively from the numeral 1 to the numeral O,-said type-numbers being respectively in the plane of the center of the respective stub-shafts 23.

Upon each of said stationary stub-shafts is revolubly mounted a typewheel, as at 26, said type-wheels thus being in a circular equi-distant series concentric to the axis of the discs 21 and 19 which move with the main shaft 15. Said type-wheels 26 revolve between the discs 21 and 19 in the intervening boxingspace 24, and each of said wheels comprises a body-disc, as at 27, adjacent the outer main type-disc 21,

. and a circular geardisc, as at 28, carried at the inner face of said body-disc. The type-wheels 26, in their body-disc and gear. are each of uniform diameter, and their body-discs are respectively provided at their periphery with a circumferential series of equi-distant type-numbers, as at 29, which are respectively adapted to come into alignment with the respective type-numbers 25 of the main disc 21 as said type-wheels are revolved independent of the main typedisc 21. Thus, each type-number 25 of the main disc 21 has a respective typewheel 26, the type-numbers of which latter are brought successively into alignment with the respective type-numbers 25.

One of said type-wheels 26 constitutes the automatic-trip type-wheel whereby the complete circular series of Wheels are ac 'tuated in simultaneous step movement. This trip-wheel is indicated at 30, (see Fig. 7), and carries a circular trip-gear, 31, extending beyond its main actuatin gear-disc 28 in the longitudinal plane of its axis, said trip-gear being projectively accommoarrangement, the trip-gear 31 has eight step-cogs respectively in alignment with the peripheral type-numbers 29 of its typewheel 30-2 The series of type-numbers 29 of all the type-wheels 26, except the wheel which is diametrically opposite the main trip typewheel (2630), run, in the present numerical arrangement, consecutively from the numeral 1 to the numeral 7 with a clear peripheral space, as at 34,- in compensation for the equi-distant succession of the type numbers, between the numerals 1 and 7, whereby the numerals 1 to 7 will be equi-distantly spaced and the clear double space 34 existing between 1 and 7 will be equivalent-to the spaced positionof an other numeral such as if 8 were employed. The type-wheel, indicated at 35, which is diametrically opposite the main trip typewheel (2630) is provided with the numeral 8, its series of numerals running consecutively from 1 to 8, without the clear peripheral space 34 as on the other type-wheels.

To effect the uniform operation of all the circular series of type-wheels 26 in a ooincident step movement, under action-of the trip-wheel 2630, a circular gear-disc, 36, is mounted in common to the entire train of type-wheel 26 and revolves upon an internal hub, 37 centrally carried at the inner face of the disc-plate constituting the main type-wheel 21, its geared periphery being in mesh with the gear-discs 28 of the entire train of type-wheels 26 which are in concentric series with relation to said main gear-disc 36.

The step-movements of the train of typewheels 26 and the main gear-disc 36 "are controlled by a pawl andratchet mechanism comprising a circular ratchet-plate, 38, carried at the face of the main gear-disc 36 towards the main disc type-wheel 21 and engaged by a spring-controlled pawl, 39, pivotally mounted upon the inner faceof said disc type-wheel 21.

Said pawl and ratchet mechanism is thus pawl 39, to enable the insert-ion of an instrument into engagement with the pawl to retain the same from engagement with its ratchet under conditions of adjustment of the type-wheels 26 in the set of their peripheral type-numbers with relation to the typenumbers of the main disc type-wheel 21.

Projectively mounted upon the framework 14 is an arm, 43, adapted to engage the peripheral step-cogs of the trip-gear 31 of the trip type-wheel 26-30, to actuate the latter in a step movement co-incident with one complete revolution of the main disc type-wheel 21. Said arm is provided with a lateral finger, as at 44, at its terminal outer end, which is positionally )roiective with relation to the step cogs of said gear 31. The operative position of said trip-arm is fixed, but inasmuch as the arm will serve to actuate the trip-gear 31 in either direction, so that the numbering mechanism can be operated in a reverse directionv under such circumstances as may be desired, the arm is preferably adjustably mounted upon the frame-work for positioning either in. forward movement or backward movement. The preferred construction for turning and fixing the arm in said reverse operative position comprises a cylindrical bore, 45, in the frame-work 14, in which bore the arm is lurnably mounted and secured by a setscrew, 46, carried by the frame and entering said bore into engagement with the arm. The trip-arm also preferably carries a laterally projective finger, 47, serving as a pointer the end of which moves with relation to a segmental scale-line, 48, upon the face of the frame-work and having at one terminal the letter F indicating set for "torward movement and at the other terminal the letter B indicating set for backward movement. The pointer-finger 47 is preferably detachably mounted upon the trip-arm 43 by a body-eye receiving the arm and carrying a set-screw, 49, engaging the arm.

It will be understood that the ticket-strip or other data to be numbered is fed beneath the type-wheels between the peripheral numbers thereof and a suitable underlying platen or bed, as indicated at 50.

The extension stub-shaft 23 of the trip type-wheel 26-30 is preferably detachably secured to the main disc type-wheel 21, for purposes of strength, by having its outer end passing through a shouldered opening, 51, in the latter and secured by a nut, 52, set against the outer face of the disc 21.

The operation and advantages of our invention will be readily understood by those skilled in the art to which the improved mechanism relates. In the numerical arrangement herein shown in the present embodiment of the invention, the mechanism is adapted to imprint numbers consecutively from 1 to the initial position of the type-wheels being such that the peripheral numeral 5 of the main disc typewheel 21 is at the top and its peripheral numeral 0 is at the bottom, it being understood that the trip type-wheel 26-30 is carried in alignment with said numeral 5 and the diametrically-opposite typewheel 26-35 having the numeral 8 as hereinbefore described is carried opposite said numeral 0 In such initial position, the complete train of ten co-acting type-wheel 26, except the bottom wheel 26-35, have their clear peripheral space 34 in alignment with the peripheral numbers 25 of the main disc type-wheel 21, while the numeral 8 of said bottom type-wheel 26-35 is in alignment with the numeral 0 of said discwheel 21. Then, in the revolution of the complete mechanism carried by the main shaft 15, the main disc type-wheel 21 in one complete revolution will imprint the numbers 1 to 9 successively, starting with the numeral 1 the trip-arm 43 being out of engagement with the trip-gear 31 of the top trip type-wheel 26-30 at the commencement of the revolution of the main disc typewheel 21 and the complete train of ten typewheels 26 remaining stationary during said imprinting action of the disc type-wheel 21. Then, when the initial revolution of the main disc type-wheel 21 brings its peripheral numeral 0 to the point of printing, and just before the imprinting action of said numeral 0, the trip type-wheel 26-30 will have arrived at the top of the mechanism and the trip-arm 43 will actuate the trip-gear of said wheel 26-30 in one step movement in which each of the train of ten type-wheels 26 will be automatically moved simultaneously, under actuation by the geardisc 36 which is in gear connection common to said train, to bring their respective peripheral numerals 1 in alignment with the respective peripheral numerals of the main disc type-wheel 21. The next number then imprinted will be 10, and in the ensuing revolution of the imprinting mechanism constituted by the main disc type-wheel 21 and the train of type-wheels 26 the numbers 11 to 19 will be imprinted before the trip-arm 43 again operates to cause simultaneous movement of the train of typewheels 26 to bring their respective numerals 2 in alignment with the respective peripheral numerals of the main disc typewheel 21. Thus, in the successive step movements of the mechanism the numbers 1 to 80 will be imprinted, the final step movement of the train of type-wheels 26 bringing the peripheral numeral 8 of the bottom type-wheel 26-35 in alignment with the peripheral numeral O of the disc typewheel 21, while the clear peripheral spaces 34 between the numerals 1 and 7 of the remaining nine type-wheels 26 of the train will be in alignment with the respective remaining peripheral numerals 1 to 9 of the main disc type-wheel 21.

When the imprint action to the number 8O is completed, the main disc type-wheel 21 and the train of type wheels 26 will again be in the initial position as before described, for imprinting the numbers 1 to 9 successively before the'trip-arm 43 again e-n-- gages the trip-gear 81 of the top trip typewheel 26-30 for the ensuing step movement of the train of wheels 26, under continued revoluble movement of the main shaft 15. Thus, the improved mechanism, in the numerical arrangement herein shown, will imprint the numbers 1 to in successive sets under automatic action in the continued revolution of the main shaft.

It will be understood that othernnmerical arrangements may be employed, as

adapted to the relative action of themain type-wheel 21 and train of type-wheels 26, according to desired conditions and circumstances of use.

For a reverse movement in imprinting the succession of numbers provided by the mechanism, it is only necessary to set the trip-arm 43 at the backward point B on the scale 18, when the engagement of its trip-finger 44 with the trip-gear 31 of the trip type-wheel 26 230, under reverse revolution of the main shaft 15, will cause a simultaneous step movement. of the train of type-wheels 26 in a reverse direction rela-V tive to the reverse movement of the main disc type-whee1 21 which is carried by the main shaft. I

The improved mechanism is exceedingly compact and affordscertain and direct auto-' matic action for continuous and successive imprinting of numbers within the range of itsnumerical arrangement without manual adjustment, and the positive inter-gear of the step-moving printing elements precludes any liability to disarrangement. The step-moving elements are also compactly enclosed and protected within the boxing or housing formed by and between the main discs 21 and 19 which are interlocked and carried by the revoluble main shaft, and it will be noted that in the details of construction as herein shown the various parts are separably so connected that the mechanism can be convenientlytaken apart when desired, for purposes of substitution or inspection or other requirements.

We do not desire to be understood as limiting ourselves to the detail features of construction and arrangement asherein shown and described, as it is manifest that variations and modifications therein may be resorted to, in the adaptation of our invention to varying conditions of use, without departing from the spirit and scope of the invention and improvements.
