This invention is 'a continuation in part of 'application Ser. No. 656,883, lecl March 25,A 1946, and issued July 25,- -1950,"as Patent No. 25516321. The invention relates to a compact numbering machine for printing numbers on checks, tickets or the like at high speed.

Ai feature of the invention is the provision 'of ar-numbering device-of compact, simplified construction which is easily assembled or taken apart and which is capable of operating at high speed.

Another `feaizln'e of the invention is the provision of a numbering machine of durable'con'- -Struction in 'which` the mechanism is mounted in a rugged tri-*partitecyli'ndiical structure ofrela'- tively small diameter which permits intermittent high Yspeed operation of the device.

Still another feature of the invention is a sirnpliiied arrangement in which the number wheels are mounted on a single sere'w which Ais removable from the exterior of the device to permit easy removal or installation of` the number wheel assembly. K

Other objects and features will be found in the following description given with the aid of the accompanying drawingsfof which Fig. 1 is front elevational View`r ofa preferred embodiment of the invention; and' Fig. 2 is" av longitudinal seetion taken tlieethrough.

Referring new -to` thedraw'ingsI Aecoidirig to a preferred embodiment ofthe invention a `sleeve I is driven` from a suitable source of power, which in 4the-case where the deviee is intermittently operated, will be the driven member ofV a suitable friction clutchj not sho'wri.l A sleeve II, providedwitha -large'flang'e I2 at one-end which forms one endet a recess or housing ferthe numbering mechanismffitsover sleeve IS; A gear I3 for operating a counter, not shown;`V is formed with a hub Ill, which together with sleeve II is fastened to the inner driven sleeve I9 by a screw I5. Flange I2 is formed With-oben oppositelyvdisposed slots I6 and I'I `e'zxtendi-hg in` an aitial direction shown'in.elevatiorl` in Fig.l 2 which will be referred to later on.

A .number wheel Lhousingx2ll generallyfcylindric'al in shape exceptV for an openesided recess 2| in which theA numbering vmechanism isY mountedhas. one end disposed-.against the faceof `flange I2 which forms la closure therefor. The opposite end of housing ZIJ` rests against a'relat-ively' thin circular plate 22 formed with a number of openvingsfor holding pawlr springs which will bedescribed below.

One face of ay widehub'23 fastened by pin 24 to ashaft 25 concentrically disposed with respeet to sleeve I0 rests against the opposite surface of 'plate 22. A slot 26'rined in hub 23 is in iegister with slot I'I`in iiange I2. Optionally, and forming, per se, no part of the invention, detachable printing dies such as date die 38 may be mounted in suitable recesses formed in hub123. Another die 3| for printing any desiredv matter may be detachably mounted in a recess alongside the date die.

A stop roller 32 'adapted to cooperate with a known type of stationary start-'stop mechanism is mounted between arms 33 and V34 of a detach; able stop arm'assembly. Rollei* 32 turns on the shank of .a screw 35 which is threaded intoV an opening therefor in an arm `36 formed integrally with shaft 2.5.

The vouter surface of number wheel housingv 2D is cylindrical and of the same diameter as flange I2 except that a wide deep longitudinal recess is formed therein having flat, parallel, opposed side walls 40 and 4I` A featureof the invention is the simplified arrangement for mounting the numbering wheels in the recess. Six number Wheels 42-41 are shown. in the present embodiment of the invention. EachY number wheel" has a ratehet wheel fixed thereto, the ratchet wheels beingvnumbered 49 to 54. The wheels are assembled between oscillatory end plates 55 `and 5B, and the whole assembly which ju'st nts between side walls lill'and 4I of the recess is mounted to turn on the shank of a screw 51 Which'is inserted into a countersunk opening therefor on the outside of housing 20. Screw 51 .extends aoro'ssthe recess between side Walls 40 and 4I and is held by a nut 58 disposedin a counter-bored opening' below the outer surface ofi housing 20.y

The number Wheels vary in diameter progressively from the middle wheels toward thek e'hd Wheels. The characterson the wheels are' formed on suitably bevelledsurfaces. so as-to prese-nt, jointlyi whenA in printing position a curved arrangement of characters of slight-ly greater diameter than the housing 20.

The number wheels areoperated by a'slide er plunger 60 'having-an outer portion which extends beyond and reciprocates in slot 26 in hubl 23,-` and an offset portion 6l which extends through'an opening in pla-te 22 and along the inner rearV 's'urface of thehousing, midway between the walls 40 and 4I thereof, the oppositeaend oi the'slide being-guided by the slot I'I in dang-e I2.` Slide 60 is free to move back andv forth inthe' sldts 26 and I'I withinthe limits imposed bythe engagement of a shoulder 64 on the tr edge ofthe slide,

with one surface of plate 22, and the engagement of a second shoulder 05 formed in oiset relation with shoulder 34 on the opposite edge of the slide which engages the opposite surface of plate 22. A suitable stationary cam indicated generally by reference character E05 is used to actuate slide 60 in the known manner as the assembly rotates.

Slide 60 passes through the housing behind the number wheel assembly and is used to oscillate the end plates 55 and 5B disposed on screw 5l' at opposite ends of the number wheel assembly by means now to be described.

Between end plates 55 and 56, an assembly of pawls '10, one for each ratchet wheel, is mounted on a spindle 'il riveted at opposite ends to the end plates. The pawl assembly is of a well known type in which the pawls are all fixed to a sleeve 'l2 free to turn on the spindle. A spring i3 tends to hold the noses of the pawls in engagement with :their respective ratchet wheels. A known carry-over arrangement may be used in which the noses 74 of the pawls are of progressively greater length, the eifective length of the pawl for the units wheel being the greatest. Between the digits 9 and G on the respective number wheels, except that for the highest order, the notches 'I5 between the ratchet teeth vary progressively in depth, the depth of 4the depression between the 9 and 0 teeth on the units wheel being the greatest. the units wheel is stepped along, the long nose of its ratchet pawl is eiective to prevent the noses of any of the higher order pawls from engaging and operating their ratchets. However, when the nose of the units pawl drops into the deep notch between the ratchet wheel teeth after the digit 9, the pawl assembly will turn sufficiently for the ratchet wheel of the tens wheel 43 to be engaged and advanced one step by its pawl. This same operation will occur until the tens wheel is turned past 9. Then, when the units wheel passes 9, the deep notches of both of these wheels will be lined up with the noses of `their respective pawls, and on the next operation, the pawl assembly will be turned sufficiently by its spring 'I3 to bring the pawl for the third or hundreds wheel 44 into engagement with its ratchet Eil .and advance the same one step. After the deep notch between the 9 and 0 teeth of the hundreds ratchet is reached and becomes aligned with those of the lower orders, the pawl assembly will turn Adjacent the number wheel assembly, plunger A60 has a notch 18 formed in its edge.

A sleeve 'I9 disposed between end plates 55 and 56 is po- .sitioned in the notch. The sleeve is free to turn on a long pin 80 riveted at its ends to the respective end plates. This arrangement provides a driving connection between the slide 60 and the pawl and ratchet mechanism. It will be seen from the drawings that as slide 60 is moved back and forth in its guideway that the end plates and 5E will be oscillated first in one direction and then the other on bearing screw 57 and this movement is used to operate the pawl and ratchet mechanism of the number wheels.

The slide 60 is retracted normally to the position shown in Fig. 2 where shoulder 65 of the slide rests against the surface of plate 22, by a pair of long retractile springs 8l and 82 attached to the end plates. These springs are disposed in spaced long holes drilled in hub 23. One end of each spring is connected to respective end plates With this arrangement, as

55 and 56 while the opposite ends of the springs are fastened respectively to pins 83 and 84 disposed transversely of :the holes encasing the springs.

Individual holding pawls 85 to 90 are provided for the respective ratchet wheels. The pawls are separated by suitable spacers which together with the pawls are mounted on a screw 9| which extends across the recess for the number wheel mechanism. Each pawl is provided with a pin 92 extending into one end of a compression spring 93 which extend into individual openings 94 formed in plate 22. The springs are easily mounted on assembly of the device by inserting them in their proper holes where their open ends slip over the respective pawl pins 92. The springs are compressed when the face of hub 23 is assembled to plate 22.

From the foregoing it will be understood that the structure of the invention comprises three parts, the flanged sleeve lI-I2, the number wheel housing 20 and the hub and shaft 23-25.

`These parts are held together by long screws 95,

one of which is shown in the drawings. The heads of screws 95 are disposed in counter bored recesses in ange i2 and extend through the structure in suitable openings, their ends being threaded into hub 23. With this arrangement, on removal of the screws, three such screws being usually employed, the three parts of the Vstructure may be separated, and as easily put together again. The number wheel mechanism is easily connected with operating slide 60. All

.that is necessary is to place the roller 19 in the notch 78 in the slide.

An arrangement for .punctuating the printed numerals by printing a long thin line between the respective groups of three numbers is provided. This punctuating device which is optional comprises an arm 91 having one end fastened in slot I6 in ange I2 by a taper pin 98. Arm 91 projects in an axial direction and is formed with a portion 99 which extends between number wheels 44 and 49 but clear of the same. An edge |00 of the arm extends outwardly in register with the surface of the digits on the number wheels when in printing position and therefore will .cause a narrow line to be printed between the adjacent digits.

The stationary cam |05 for operating slide 60 is not shown in detail because it is thought the operation of a relatively movable slide by a stationary cam is well known. However, it will be understood that the cam may be designed to operate the slide during a considerable part of the angular movement of the device during each revolution thereof which will permit smoother operation of the pawls than the usual arrangement where a rotating pawl operating arm is struck against a stationary stop.

While the device is designed primarily for intermittent unidirectional operation, it will be ,understood that it will operate just as well when Vused with continuously driven apparatus.
