To all whom it may concern:

Be it known that I, AMos H. SMITH, a citizen of the United States, residing in the borough of Bronx, in the city, county, and State of New York, have invented certain new 1 and useful Improvements in Numbering-Heads, of whichthe following is a specilicatiomieference being had therein to "the accompanying drawings, which form a part thereof.

and more particularly to means for preventing the accidental actuation of a digit wheel of higher denominanext lower denomination. 1 V

The main object of the invention is to provide a numbering head wherein the transfer mechanism will successively actuate the digitv type Wheels, and whereinthese wheels will be normally locked in a manner to prevent the actuation of any digit wheel resulting in the accidental actuation of an ad-' joiningdigit wheel of next higher or lower.

'- denomination, while being automatically released as the transfer mechanism becomes operative in relation thereto. 7

A further object is to provide a-locking mechanism which will be efiective to pres" vent the rotation of any digit wheel ex'cepting the units or primary wheel at all times except when the erative in relation to a particular wheel.

A still furtherobject is to provide a I ium-. boring head wherein each of the digit wheelswill be normally locked by .a mechanism under the control of the digit wheel of neat higher or lower 46 sure a timely release of the locking mechdenomination, so as to inmsm. v A still further object is to boring head wherein when any digit wheel of higher orflower denominationfshall be untime when the transfer mechanism is not about to become operative with relation thereto, there will be ositioned between said wheel and t e umt or primary locked at a 1- wheel, at least one digit wheel which will be of this characterxembodying tomatically acting mechamsmi'which will t e various digit wheels as locked'so as to prevent theaccidental actuation of the unlocked wheel. And astill further object is to provide a numbering head therein an aulock and release required, and which may. be applied to the Specification of Letterslatent.

ing with the other operative parts thereof, o'r necessltatmg a change in the design or dimensions of the head.

7 The invention consists primarily in anumberm head embod ing therein a plurality of in ependent, digit type wheels, a transfer mechanism whereby said wheels are succes sively rotated in carrying from one denomination to another, locking means normally.

holding all of said wheels excepting the unit or primary wheel against rotation, and means operative by the wheels in their sequence of operation whereby said locking means will be rendered inoperative as each wheel is actuated in its order by said transfer mechanism; and n such other novel features I of construction and combination of parts as are hereinafterset forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings :-Fi gure '1 is a plan view of a number head embodying my invention, a portion thereof being shown in section; Fig. Qis a side View of one wheel, of Fig. 1; Fig. Bisa side view of an adjoining wheeh'taken on the line 3-3 of Fig. 1; Fig. 4 is'a perspective view of the shaft; and Fig.

nation is liable to be time accidentally" actu- I atedywhile if in a descending progression a wheel of lower denomination is'liable to be thus accidentially turned.

Inasmuch as ac curacy is essential to certain lines of work,

bonds, stock certificates, not to spoil an head wherein as bank notes,. drafts, checks, etc, in order edition or series, a numbering such an accidental actuation of a wheel outv occur is desirable'- y of its order cannot In the accompanying drawings, 1 have shown my invention applied 'toa numbering head of-well knownoonstruction I In the said drawings; a indicates i reference to a machine of this type, it being understood, however, that this mechanism may be reversed to have the head print in a descending progression, as when it is desired to have the numbered articles arranged in piles with the lowest number uppermost. Each of the wheels 0, c, 0 c 0 c is provided with a ratchet d, d, d d d", d engaged by a spring pressed pawl e, 6', 6 ,6

\ e 6 and adapted to accurately position each wheel for printing and hold it against movement while the types are being inked. Each of said wheels is provided with printing type from 0 to 9, there being a ratchet for each character.

Mounted in the frame a is an impact plunger f adapted to actuate the unit or primary wheel a by means of the spring pressed pawl g cooperating with the ratchet d, and the transfer mechanismwhich will be more fully described hereinafter. Said pawl and said transfer mechanism are carried, and actuated, by an oscillatory frame 71 under the control of the plunger f.

The transfer mechanism comprises agrad-x uated series of pawls 'g' g g g which together with the pawl g are pivoted upon the frame 72, and are spring pressed toward the wheels 0 to c inclusive. All of these pawls act in unison, and are adapted to enter recesses z in each of the wheels 0 to c inclusive, the varying heights of these pawls determining the operative relation of the transfer mechanism to the wheels adapted to be actuated during the transfer operation. For instance, if the figure 9 upon the unit or primary digit wheel 0 be in the printing position, the pawl 9 will enter the recess 71 in this wheel, thus permitting, the pawl g to engage the ratchet of the wheel a, theremaining pawls g to 9 being thus'held out of engagement with their respective ratchets and prevented from assuming the operative relation to their wheels. The pawls g to g, with the continued operation of the head, will successively drop into the recess i in their respective ratchet wheels, thus causing the pawl actuating a wheel of lower denomination, to normally hold the pawls of higher denomination out of engagement Withtheir wheels, but permitting such engagement once during each rotation of such wheel of lower denomination.

my invention is capable of application. In

this type of head as now used, all of the digit wheels are capable of being simultaneously advanced independently of the transfer mechanism, as in case of the accumulation of dried ink between the wheels, and it is to obviate this condition that T'have 'developed my present invention.

In carrying out my invention, I provide the shaft Z) with a series of peripheral recesses j, one adjacent to each tooth of the ratchet of each digit wheel. 0 to c inclusive, and mount in this recess a bolt k adapted to be thrust substantially radially of the shaft 6 by means of a spring k. Preferably this bolt and spring are made of an integral strip of spring metal with an angular end acting as the bolt is, a construction which lends simplicity to the structure while at the same time affording the desired resistance to the rotation of a digit wheel locked'thereby and permitting the necessary compactness of structure. This bolt is is of a width to project across the space between two adjoining digit wheels, thus positioning it so that it will be capable of locking one of these wheels and of being released by the adjoining wheel of lower denomination. Each digit wheel 0 to inclusive upon one side thereof is provided with a plurality of angular recesses or sockets m adapted to be engaged by the bolt is to lock this wheel against rotation in either direction, a recess or socket m being provided for each character carried by the digit Wheel. It will thus be observed that when the head is set at zero throughout, every digitwheel excepting the unit or primary wheel will be locked against movement in either direction. lease of thesedigit wheels and permit the free rotation of any wheel under the control To accomplish the rep of the transfer mechanism only when it is required to carry the wheel of next higher denomination through this mechanism, T provide each of the wheels 0 to c inclusive upon the side thereof adjacent to the wheel of next higher denomination with an annu lar channel n about the shaft 1), at one point whereof determined by the figure Q-cominm to the printing position, is a cam o adapte to engage and depress the bolt k in a mannor to actuate thisbolt and release the wheel of next higher denomination. In order to secure the desired result, it is necessary that the bolt k should project from adjacent to one wheel into this channel so as to be engaged by this releasing cam,

The operation of the herein described device is substantially as follows: With each impression from the head, the plunger 7" is depressed and the name it oscillated to admatically actuated. Vi

the unit or primary wheel socket m of the wheel Vance the pawl 9 one tooth and cause its spring to bring it into'that relation to the ratchet d to cause the return oscillation of said frame to feed this wheel forward ne character. During this operation all of t e wheels 0 to a are locked by the bolts k, the wheel 0 in the head shown not being autoith the repetition of this operation, will be advanced until the figure 9 is in the printing position, whereupon the pawl y will drop into the recess i of this wheel a, permitting the pawl g to engage the ratchet 0Z of the type wheel 0 preparatory to the transfer operation from the wheel 0 to the wheel 0'. As the figure 9 approaches the printing position, the cam o of the wheel 0 will engage the bolt is controlling the digit wheel 0', which prior to this time has been seated in the channel n of that wheel, so as to permit the free rotation of the wheel 0',

and depress" it against the tension of the spring is into the recess j in the shaft 1) in a manner to cause this bolt to recede entirely from the socket m and thus release the said wheel 0. Upon the return-movement of the frame It, the wheels 0 0 will advance one figure in unison, the spring is upon the completion of this movement forcing the bolt is into the next recess or bolt 0" and locking this wheel against further movement until the next transfer operation. This operation is repeated, the wheels 0' to 0 moving to present numbers in arithmetical progression.

It will be observed that the only wheel moving under power except. during the operation of transferring from one wheel to another, is the unit or rimary wheel a, and that except when the gure 9' of any wheel is in the printing position, the wheel of next higher denomination is locked against movement. Assuming, however, that the wheel 0 in the tens place, has the figure 9 in the printing position, the wheel 0 in the hundreds place will be unlocked. But unless the wheel 0 has its figure 9 in the printing position, the wheel 0 will itself be locked against movement, so that no accidental movement of the wheel 0 can occur. In

fact, no movement of the wheel 0 can occur until the figure 9 on both wheelsc and 0 is in the printing position, whereupon w c c and 0 which, as stated, is already unlocked, will be simultaneously advanced one figure. Hence even though any wheel 0 a a or. c be unlocked, none of these can be turned so long as there is at least one wheel between it and the unit or primary wheel 0 which is locked. While the various wheels 0' to c are normally locked,

the head may be set to any desired number I by turning the wheels in sequence from the wheel a,

printing position in each.

heels so-as to bring the figure 9 tothe It is not my intention to limit my inventionto use with thestype of numbering head shown in the drawings, nor to the. precise details of construction illustrated, it being apparent that it may be used with various types of heads, and that such details may be varied without departing from the spiri and scope of the invention.
