HAND PERFORATOR.

Application iled May 3l,

To all whom t may concern Eo it known that l, HJALMAR SWANsoN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a neu'and useful Improvement in Hand Perorators, of which the following is a specification.

This invention relates to hand perforators, and has for its object to provide a simply constructed though .highly eiiicient device of this character which may be carried aroundupon the person of the operator, and which embodies, among other features, provision for punching data that is changed automatically at each operation of the periorator, the changeable data being preterably punched in combination with the punching of non-changeable data. By the invention, a salesman, for example, or other operator, may punch on successive slips of paper, such as sales tickets, different data on each ticket, as successive numbers which are changed automatically at each punching operation, the successive numbers indicating successive sales and being peferably combined With the punching of fixed dalla on each sales ticket to indicate the particular salesman making the sale. lVhen employed in the manner above set forth, the invention provides perforating equipment that is especially suitable for large sales organizations7 such as department stores, in that the use of the improved hand perforator will furnish a practically unalterablc record of the sales made by each individual salesman.

l'n addition to the general objects recited above, the invention has foriurther objects such other improvements and advantages 'in construction and operation as may be found to obtain in the structures and devices hereinafter described or claimed.

The same characters of reference designa-te the same parts in each of the scve al views of the drawings. y i

In the illustrated embodiment of the invention, the hand perforator is especially designed for being used in the manner and for the purposes above specified and, for

convenience, the present description Will be confined to this use of the invention.

Features of construction of the hand perforator are, however, capable of other applications; hence, the scope oi' the invention is not confined to the specific use and specific embodiment herein described as an illustrative example.

Referring to the drawings: The hand peri'orator embodies in its construction a pair of movable jaw members 11 and 12irespectively provided, at one end With

handle grips

13 and 14, and pivoted together, at the opposite end at 15. A spring 16, the opposite ends of which seat in

sockets

17 and 18,

provided in the

members

11 and 12, maintain said members normally apart from each other.l a position in which the several punches are retracted from the dies. The sheet or sheets or paper to be punched are inserted in an open slot 19, extending longitudinally in the jaw member 12. Situated in said member 12 at the bottom of the slot 19 is a die plate 20, the dies of which communicate with an opening 21 below the die plate for the discharge oi the punched articles of paper.

In the present instance, the die plate 20 is provided with two series ot dies A and B, the former co-operating with a punches for periorating the fixed data and the latter col-operating with a series o punches for peri'orating the changeable data. The fixed data dies A are furthermore divided into two groups aand a tor co-operation with corresponding' groups of iixed data, punches, each said group ot punchescoacting with its corresponding group or dies to perforate a character ot the iixed data, such as a digit ci a two digit number' designati-ng, or example, the particular person operating the punch. rthe changeable data dies are also sub-divided into two groups 7) and b, each group co-oierating with a corresponding group oi the change able data punches to perforate a character.

The punches 22 are divided into tivo ser A and B', and the series rif, B are respec tively subdivided into groups of punches 0:? and a3 and Z22 and 3; the groups c2 and z3 co-operating respectively with the groups or" dies a and a, and the groups and 3 co-operating respectively with the groups dies and in the manner above stated. Both series'of punches i-i and l" extend into a chamber 23 pro ,d in the jaw member l2, and the lower ends of said punches, when in advanced position with respect to their corresponding dies extend through perfor-ate. guide plate 2d located below the chamber 23 and forming the top of the pa per receiving slot 19. Willen in the retracted position, the upper ends off 'the )anches cxtend through a top guide plate 25, which forms the top of the chamhe The punches 22 are further guided in their advancing' or retracting movement, by a soit metal filling 26 located above the lower guia e plate 24.

p The punches A of the xed data series are operated by a fixed or non-adjustable matrix 27, which preferably consists of a plate iixed to the lower face or" the jaw member 11 and movable to advance the fixed data punches A into their coresponding dies A, during the operation oit squeezing together the handle grips 13 and 111- oi the two

jaw inembers

11 and 12. In the form shown, the matrix 27 is reversely socketed for each group of punches a2 n?, so that it will series ot Leraars not operate those punches ot the groups which are not required for perforating the particular characters desired. During the operative movement of the matrix 27, the punches not required pass idly through the reverse sockets in the iixed matrix and only hose punches which are required for punching the characters desired are engaged by the face of the matrix and advanced into co-operation withtheir respective dies.

The changeable data punches B are operated by adjustable or revoluble matrices 29, there being one matrix for each group 52 and 3 oisaid punches B. The adjustable matrices 29 are preferably constituted of rings which revolve upon a fixed arbor 30 secured in the bifurcated portion 32 of the jaw member 13.. Each matrix ring 29 is preferably provided with a series of matrix faces 31, preferably ten in number, one for each of the 9 digits and one for O, the matrix faces 81 being also reversely soclreted, so that they will not operate those punches ci' the groupV which are not required i'or printing` the particular character desired. The matrix rings 29 are held in proper position for the operation orn each oi their matrix faces by positioning` members 28 which are moved by springs 33 into one of a series of sockets 34 formed in the inner circumferential portion of each matrix ring. When the positioning members 32 are seated within sockets 34 of their respective matrix rings, a matrix face 31 oiE each ring is in proper position for operating its correspond ing group or changeable data punches.

ln accordance with the invention, provision is made for changing the data punched by the series of punches B on each operation oit the peritorator. In the present embodt ment or' the invention, which employs two matrix rings 29, one of said matrix rings functions to punch digits of the units order, and the other functions to punch digits of the tens order. Consequently the tens order matrix ring is advanced one numeral space at each complete revolution of the units order matrix ring, that is to say,-when ever the units matrix ringis passing from 9 to 0. To accomplish this result, provision is also made for transmitting carrying impulses to the higher order matrix ring each time the lower order matrix ring passes from 9 to (l. Secured to each matrix ring 29 is a ratchet 35 having ten teeth 36, respectively companion to the digital matrix faces ot their respective matrix rings. The ratchets 35 are prevented from rotating reversely by means of back stop pawls 37. As shown in Figs. 10 and 11 the tooth 37, opposite the 9 matrix face of thel units order matrix ring is cut deeper than Jthe other teeth 37 of said units order matrix ring, the purpose of this construction appearing hereafter. Secured to the lower Vil lil() .jaw member 12 is an upright 38, which supports at its upper end a slideway 39. l/Vorlr` ing within'said slideivay 39, is a slide pawl 40, that is yicldingly urged toward the ratchets by a spring 41 bearing against said pawl. The pawl 40 is provided at its forward end with a relatively long detent 42 for engagement with the teeth of the ratchet ot the units order matrix ring and With a relatively short detent 43 for engagementfwith a tooth ot the tens order matrix ring whenever a carry is to go over from the units to the tens arder. The detent 42 is made long enough to engage a, tooth of the units order ratchet at all times, and such engagement is eifective to advance the units order matrix ring, onev matrix tacegat the beginning oit the operation of squeezing together the

handle members

13 and 14 ot' the perforator. The other detent 43 of the` pawl is, however, made too short to engage a tooth oi the tens order ratchet, except when the tooth 37a of the units order ratchet is positioned to receive the detent 42, which 4happens when the 9 matrix face of the units order ring is positioned for cci-operation with the punches B. The greater movement allowed the pawl 40 by such positioning of the tooth 37a, brings the detent 43 forwardly into position for engaging and operating the ratchet of the tens orner matrixcring, during the next operation of the perforator, thereby transmitting a carrying impluse to the tens order matrix ring. The completion of the carrying impluse, is accompanied by a movement ot the tooth 37a away from the detent 42, with the result that the detent 43 is again retracted into inoperative position, until a further complete rotation of the units order matrix ring has been yeffected to require the transfer of another carrying imp-luso. During the retracting movement of the

jaws

11, 12 of the perforator, the detent or detents of the paWl 40 pass idly over the ratchet teeth 37.

Provision is alsomade for locking the hand perforator against further operation, when it has been operated to the limit ot its capacity. Formed in the face of each matrix ring 29 is a transverse slot V44, the slots 44 ot the respective rings being in alignment with each other, when the matrix faces are in position for punching the highest number that may be punched by the pci-iterator, in the present instance, the numbei' 99. Supported ina chamber in the upright 38 Ais a spring pressed stop pawl 45 which moves into the aligned slots 44 and prevents further rotation of the rings 29, as soon as` said rings have arrived at the above designated punching position. The locking of the rings by the pawl 45 prevents setting ot the perforator to begin another series ot punching operations. rRelease of said rings is eiected by means or a releasing rod 4G rotatably mountcdin the pper jan' member 11 anil provided'with a ug 7,

member 49 secured to the side :tace oi the upper Jaw member 11.. .An ordinary padlock may be inserted into tno holes of the locking

members

48 and 49 te prevent the release ot the pawls 45 and re* setting of the matrix rings, except by one having the authority to do so.

ln order to prevent accidental operation of the hand pertorator, when carried about on the person et the operator, there is provided means for maintaining the

jaw mein bers

11 and 12 normally in their retracted inoperative position. Pivotally secured to the lower handlegrip 14 is an arm 51 which passes upwardly througl'i a slot 527m the upper handle grip 13. Near its upper end the arm 50 is provided with a shoulder 53 adapted to engage a. lug 54 carried by thc upper handle grip 13 for the purpose of maintaining the handle grips 13 and 14 and the

jaws

11 and 12 normally retracted from. each other. A spring 55 maintains the shoulder 53 normally in vengagement with the lugs 54. Whenever it isdesired to operate the punch, the operator may by the movement ot his thumb tilt the arm 50 for ward slightly, so as to disengage the shoulder 53 from the lug 54, with the result that the arm 50 will pass freely through the slot 52 in the upper handle grip 13.

When pressure is released from the

handles

13 and 14 of the jaw .

members

11 and 12, the spring 16 restores said jaw members to their retracted position. The move ment of the members 1l andk 12 to such retracted position is accompanied by a concurrent restoration ot the previously oper ated punches ot both series A and B to their normal position. For this purpose, each punch 22 is provided with a fixed collar 56, adapted Yto be enga ed by the upper face of a perforate plate 5r, through which the several punches extend. The plate 57 supported by side members 58 carried by the jaw member 11, and, as the latter moves away from the other jaw member 12, the plate 57 engages the collars 56 of the several previously operated punches and restores them to their normal. retracted position.

The invention as hereinabove set forth is embodied in a particular form of construetion but may be variously embodied within the scope of the claims hereinafter made.
