INVENTOR ATTORN EY Patentedliem 5, 1 939 runcnmc momma Frederick L. Fuller, West Orange, N. J., assignor to International Business Machines Corporation, New York, N. Y., a corporation of New York Application August 16, 1938, Serial No. 225,084

8 Claims. (01. 164-112)- This invention relates to punching machines which are capable of perforating records such as tabulating cards to represent data pertaining to a sale. More specifically, the invention relates to machines of the manually controlled type, whereby the operator may predetermine the data to be punched upon the tabulating card, so that for each operation of the machine a card will be punched so as to be capable of controlling tabulating and statistical machines of a type now on the market.

The present machine is specifically designed for use in connection with mercantile establishments known as cooperative stores and which stores are primarily concerned with the selling of articles such as food, clothing, etc. Stores of this type dispense or sell articles which are purchased in the usual manner and distinguish from other types of stores such as independently operated stores, or chain stores, in that the profit made by a group of co-operative stores is returned as dividends to the customers in amounts commensurate with the amount of the purchases made by the respective customers. Each store has a number of customers dealing with that particular establishment and these customers are generally known as members and for each member an account number is allocated. Obviously, the amount of profit which is returned at the end of a period to the different members is based upon the amount of purchases made by that customer. It has been the practice to utilize printed or written slips in the accounting operations to determine such statistics, and if performed with the aid of customary bookkeeeping methods, it is a very laborious task entailing a great deal of time and requiring many adding machines and persons for accomplishing this procedure. This accounting operation is, of course, greatly complicated when the various members of one co-operative store trade or purchase articles in the various stores, since it is necessary that the purchases made by members be credited to the members irrespective of where the purchases are made.

The present machine, by virtue of the fact that a tabulating card is punched pertaining to each sale or transaction provides the original record for the determination of the necessary statistics. These tabulating cards are punched to represent the amount of the sale, the member number and other designations pertaining to-the transaction and by means of the member number designation they are capable of being selectively sorted so that the transactions pertaining to each memetc. the cards may be sorted into other groups for sales analysis according to other classifications.

It is, therefore, the main object of the present invention to devise an improved key-controlled 10 machine which is capable of punching a tabulatlng card and in the same operation of the machine to print a record strip and also issue a check, and to print upon the record strip and issued check data pertaining to the transaction. 15 The record strip, as is well known, is contained within the machine so as to provide'an unchangeable record of all the transactions made therein. The checks issued by the machine contain the same data as on the record strip and are 20 given to the customers as receipts of the transactions and may be utilized by them if they should question the totals of their purchases.

A further object of the invention, especially in connection with the punching mechanism, is to devise an improved means of construction of punch slides and an improved means for causing an operation of the punch pins of the punch slides and the positive retraction thereof at the termination of the punching operation.

A further object in connection with the card punching mechanism is to provide an improved form of card feeding device which will feed the cards with certainty and to accomplish eflicient card feeding operations by mechanisms which are simple to construct and positive in operation.

The last mentioned object is obtained by causing the group of tabulating cards to be punched to be resiliently urged towards a feeding roller which upon its rotation engages and feeds through the 40 punch mechanism the uppermost card of the stack.

A still further object of the invention in connection with the card feeding mechanism is the provision of means for depressing the stack of 45 tabulating cards so that the aforementioned feeding roller can feed only a single tabulating card and not accidentally feed more than one card during the same cycle .of operation of the machine.

A still further object of the invention is to provide a locking mechanism for the machine whereby the motor release bar which is operated to cause the operation of the machine cannot be 6 tion line designated 22 in Fig. 1.

the supply hopper is exhausted and (2)-.when a I card fails to feed from the supply hopper to the punching mechanism or is improperly positioned in the punching mechanism. a

The provision of the aforementioned locking and interlocking mechanism requires the proper operation of the machine and thereby insures that each transaction entered in the machine is properly recorded and represented by a punched tabulating card.

While the invention has been shown in connection with a machine of the type previously described, any one or all of the improvements described herein may be utilized in connection with a variety of machines and the present embodiment is to be considered-merely as illustrative and not restrictive.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings, whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

puhchinB slides of Figs. 26 and 2'7 are'each combined views in I The arrangement of the. keyboard of the present machine is disclosed in Fig. 1 and the keys comprise a plurality of banks of depressible keys, which are depressible by the operator prior to a I cycle of operations of the machine so as to control certain functions.

The two keys designated 20 (Fig. l) at the extreme right of the keyboard are two keys which control a printing or perforating means to designate the initials F" and D" representing the clerks operating the machine.

The numerical value entries in the present machine are preferably made in accordance with the English monetary system and the value entries are controlled by a plurality of banks of keys comprising six banks and these keys are designated by the reference numeral 2|. The three keys at the extreme right of the six banks comprise keys for controlling the entry of fractional pence The next bank of keys controls the entry of pence from the amount 1 to *11. The next two banks of keys are for controlling the entry of shillings while the remaining two banks control the entry of pounds in the English monetary system.

At the left of the machine there is provided a keyboard comprising six banks of keys and five of these banks of keys 22 are utilized for controlling the entry of the member number which comprises an account number of the customer making a purchase in the particular store in which the machine is utilized. r

The bank of six keys designated by reference numeral 23 at the extreme left are for controlling the entry of the type of transaction.

ararpor g the contacts 49 closed during the engagement llotiiae power for the mm The motive power for. the machine is derived from an electrical motor (Fi 10) which is set in operation to operate the various mechanisms by means of a motor release bar designated by reference numeral 24 (Fig. 1).

The armature shaft of the motor 25 is adapted through a speed reduction mechanism in a casing 26 (Fig. 10) to rotate a shaft 21 which carries a ratchet toothed'clutch wheel as (see also Fig.

11). Through a clutch mechanism, now to be described, a drive shaft 29 is given a singlerevolution for each operation of the machine.

Referring to Figs. 10 and 11, the stem 30 of the. motor release bar 24 is adapted by its manual depression to engage with a stud 3i carried by an arm 32 and rock said arm, and a sleeve 33 connected to said arm, in a counter-clockwise di-.

rection. To said sleeve there is secured an arm 34. Loosely mounted upon the sleeve 33 is a clutch control arm 35 which is in the plane of a clutch dog 36 pivotally mounted at 31 to a disk 48 secured to the aforesaid drive shaft 29. The arm 34 carries a stud having two diameters; 39 and 40, so that when the arm 34 is rocked the larger diameter 39 of the stud will engage a projection 4| of the clutch control arm 35 thereby rocking the clutch control arm so as to disengage its hooked end 42 from the clutch dog 36. A spring 43 will, thereupon, be effective to rock the clutch dog 36 so that a clutch tooth 44 thereof will 'engage one of the clutch teeth of the ratchet wheel 28 which is now at rest.

Upon a further rocking movement of the arm 34 the smaller diameter of the stud carried by the arm 34 will engage 'one arm 45 of a bell crank so as to rock a hooked end 46 formed on another arm 41 of the bell crank out of engagement with a notch in the disk 48 secured to the aforementioned drive shaft 29. The disengagement of the hooked end 46 of the arm 41 will thereby unlock the shaft 29 for rotation. As the arm 34 is still further rocked the arm 45 of the bell crank will cause the closure of contacts 49 to thereby electrically connect the motor 25 to the current supply S, as shown in Fig. 11. The armature shaft will thereby rotate the ratchet wheel 28 through the speed reduction mechanism just described and through the clutch connection, which was previously made between the clutch dog 36 and the ratchet wheel '28, the shaft 29 will rotate together with the disk 48 and a supplemental disk 50. The proper operation of the machine requires that the operator withdraw his hand from the motor release bar so that the latter may be elevated to normal position by means of a spring, not shown, and this will permit a spring 5i connected to the arm 34 to rock said arm back to normal position. The arm 34 is provided with an extension carrying a lug 52 and to said lug and extensions 53 and 54 of the bell crank 454'l and clutch control arm 35, respectively, there are connected individual springs 55. Obviously, when the arm 34 is rocked reversely to its normal position by means of the spring 5| the spring 55, connected between the lug 52 and the extension 54, will rock the clutch control arm 35 reversely so as to engage the extremity of the clutch dog 36 when a full revolution has been given to the shaft 29 thereby engaging the clutch dog 36 to cause it to be rocked to effect the disengagement of the clutch tooth 44 from the ratchet wheel 28 by a reverse action. It is preferred to provide means for retaining of the clutch and this is provided for by means of the disk 48.

It will be seen that when the hooked end 42 is disengaged from the notch of the disk 48 and the disk 48 thereafter rotated in a clockwise direction, the circular periphery of the disk 49 will retain the bell crank 46, 41 in rocked position thereby retaining the contacts 49 closed during the clutch engagement.

The safety disk 60 is also carried by the shaft 29 and is provided with a recess which includes an inclined cam edge 56. When the arm 34 is rocked an extension 51 of the arm 34 will enter in the notch of the safety disk but upon the initial clockwise rotation of the disk 50 the cam edge 56 will coact with the extension 51 thereby rocking the arm 34, sleeve 33, and arm 32, in a counterclockwise direction positively forcing the stem 30 of the motor release bar to normal position. The concentric edge of the safety disk 50 prevents the motor release bar from again being depressed during the operation of the machine. Hence,- the motor release bar 24 cannot be held down during the operation of the machine. Rocking of the arm 34 to normal, will, of course, through the spring 55 tend to rock the bell crank 45, 41 to normal to tend to open contacts 49 so as to open the circuit of the motor 25 but the engagement of the hooked end 46 of the arm 41 with the concentric edge of the disk 48 will keep the bell crank shifted to retain contacts 49 closed for a complete revolution of The details of construction of the keyboard will be explained and described in connection with Figs. 2 and 5 which disclose the keyboard arrangement for a single bank of keys. With the exception that the various banks of keys may vary in position and number, the construction of each bank is substantially identical.

The keys are of the usual'key-set type and comprise key stems 56 (Fig. 3) provided with key caps 59 carrying indicia, such as numerals and letters, indicating the digit or character of the particular key. Each of the key stems 58 is slidably mounted in a U-shaped support plate 60 and 6| (see Fig. 3) and each of the keys is manually depressible against the action of a spring 62 which returns the key to normal after it has been released. Each of the key stems is provided with a wedge-shaped lug 63 adapted to catch underneath a detent plate 64 so as to retain the key in depressed position. Fig. 5 shows very clearly the manner in which a key is depressed and held in depressed position, this key being the '5 key of a bank.

It is desirable that the depressed key of a particular bank and all the undepressed keys be locked against manipulation during the operation of the machine and this is provided for by the following described means. Loosely mounted upon a rod 65 (Fig. 2) is a bell crank '66 having a projection 61 cooperating with a portion 66 of a cam 69 carried by the operating shaft 29. This relationship is effected by means of a spring 10 secured to one arm of a bell crank 66, which is connected to an arm 1| secured to a rock shaft I9 (Fig. 5) by means of a link I2. Loosely mounted upon a rod-I8 is a spring pressed bail I4 and one side of bail I4 is provided with an extension I6 coacting with a cam plate I6 which is secured to the rock'shaft 5 I9. At the initial operation of the machine the cam 89 is rocked in a clockwise direction, as viewed in Fig. 2, permitting spring I to be eflective to cause the projection 61 to drop 03 the high part 68 of the cam 69 to rock the bell 1o crank 66 and to cause the link 12 to be depressed. This will rock' the shaft I9 and cam plate I6 counterclockwise causing a projection 'II thereof to strike a side arm of the bail I4 and move as shown in Fig. 5 bail I4 to-the rear of the extremity of all the detent plates 60 provided for I each of the banks of keys. Locking of the detent plates 64 in this manner will prevent accidental release of the depressed key and also prevent depression of any ofthe unoperated keys in all banks and this locking action is maintained during substantially the complete operation of the machine by virtue of the fact that the bail I4 will be maintained in its elevated 1 position (see Fig. 5). It is, of course, desirable to release the depressed keys at the completion of the operation of the machine and to effect this operation another high portion 18 of the cam 69 will, at the termination of the machine operation, rock the '30 bell crank 66 clockwise so as to elevate the link "I2 and depress the bails I4 to unlock the detent plates. Attached to the shaft I9, to which the arm 'II and cam plate I6 are connected, is a .bail 80 andsaid bail overlies a plurality of bell cranks 8|, the upward arm of which 'passes through an aperture in the related detent plate 64. By the depression of the bail 80 the bell cranks 8| will be rocked counterclockwise shifting each of the detent plates 64 rearwardly to .1 disengage the wedge-shaped lug 63 of the .de-

y pressed key from the detent plate permitting the related spring 62 to restore it to normal position.

Difierential mechanism scribed in connection with Figs. 2 and 5 and the bank of keys disclosed therein, it being under- -.stood that the construction of the remaining banks is similar. Attached to the drive shaft 29 is a pair of complementary cams 90 (Fig. 2) cooperating with follower rollers carried by an arm 9I loose on a stud 92. The arm 9I has an integral segment 93 meshing with a mutilated gear 94 secured to a rock shaft 95. To the rock shaft 95 there is'secured a pair of double arms 96, the upper extending arms carrying a rod 91, and the lower arms carrying a rod 98.

A sector or gear segment 99 is supported by the rods 91 and 98 and thereby partakes of the reciprocating movement effected by rocking the double arms 96. The teeth of each of the pair of 'gear segments 99 mesh as shown in Fig. 25 with the teeth of a related one of a pair of rack slides I00, and each rack slide I00 is provided with a longitudinal guide slot IOI receiving a fixed guide rod I02 and a longitudinal guide slot I03 receiving a fixed guide rod I04. By any suitable mounting means the pair of rack slides support and carry a transverse bar, there being provided a bar I06 for the six banks of keys at the left and by a-similar construction of arms 96. rods '98, segments 99, slides I00, a bar I0'I'(Fig. 10) is reciprocatedfor the differential mechanism of the seven banks of keys at the right (Fig. 1).

engaging slide IIO (Fig. 3) and The differential mechaism will now be de- Obviously, referring to Figs. 2 and 5 the bar I06 is reciprocated for each operation of, the machine being moved from right to left, and then left to right and for each machine operation an invariable amount. I Also slidably mounted on the guide rods I02 and I04 there is a supplemental rack slide I08,

one for each key'bank, and each of said rack slides I08 meshes with a related segment I09. Also mounted on the guide rods I02, I04 is a dis- 1 the slide, H0 is mounted adjacent'the slide I08. The slide I08 carries a pair of pins III received by slots formed in the adjacent disengaging slide IIO so that the disengaging slide II 0 may move a slight amount 1 independently of the related slide- I08, for a reason to be made clearer later, and in this instance 'a spring I I2 interposed between tongues carried by the slides I08 and II0 may be compressed. Namely, the slides I08 and H0 move as a unit.

The slide I08 carries a pin 3' which is the pivot pin of a latching pawl Ill which is provided with a hook II5 (Fig. 2) normally catching over the rear edge of the bar I06. The pawl Ill has a slot receiving a lug II6 of the disengaging slide IIO. In the normal position of the slide I08 a depending extension II I of the slide I08 receives the forward edge of the bar I06 and together with the hook II5 it will be seen that the slide II 0 is latched to. the bar I06 and thus is reciprocated by the bar I06. The compression of spring II2 acts to shift the slide IIO so as to be latched to'the bar I06 and thus is reciprocated by the bar I06. The compressionof spring II2 actsto shift the slide IIO a slight amount independent of the slide I08 thus maintaining by the lug II6 the rocking of the pawl II4 to cause the hook II5 to firmly catch over the rear edge of the bar I 06. Obviously the movement of the bar I06 to the rear will move the slides I08, II 0 correspondingly thus positively rocking the related segment I09 in a'counterclockwise direction until the slide H0 is stopped in a manner now to be set forth.

Referring to Fig. 3 it will be seen that the key stems 58 are provided with depending extensions I I8, bent into four planes and that the slide I I0 also is provided with upstanding extensions generally designated by numeral 'I I9, and also bent in four planes to be correlated with the planes of the extensions II8 of the keys This correlation is efiected so that each key extension II8 will coact with its related stop extension II9 to determine and effect the proper differential movement of the slides II 0 and I08. For example, stop extension II9 will be stopped by the extension II8 of the I key, the stop extension II 9 will be engaged by the extension II8 of the 5" key; as shown in Fig. 5, etc., the extensions being so arranged that the effective key extension II8 will coact only with the related extension of the slide IIO.

When the extension I I8 of a depressed key coacts with the related stop extension I I9 the slide I I0 will be positively stopped in its movement but latch pawl III will continue to move the slide I08, compressing the springs I I2 and at the same time rocking the pawl 4 since it is held by the lug I I6 to cause the hook I I5 to be disengaged from the bar I06 so that an extension I20 of the pawl will catch under teeth of a bar I2I, the cooperating teeth being so shaped as to maintain. this relationship effected by the compression of differentially set positions for a while to permit.

ing the slides I08 and H0 to the spring III. Bar I00 may now continueits movement to the rear. I

In this manner the keys determine thediflerential movement given to slides I08 and the driven segments such as the segment I09, for the key bank disclosed in Figs. 2 and 5.

The segments I09 are maintained in their certain operations of the machine and thereafter the rod 91 will coact with these segments and restore them to normal. The bar I08 will, of course, also engage the extensions I I1 of the slides I08 rocking the pawl H4 out of engagement with the teeth of the bar I2I, and thereafter restornormal position shown in Fig. 2.

Printing mechanism The diflerential movement communicated to the segments I09 is adapted to differentially set a series of punch pin carrying slides so as to punch a record, as well as type carriers to also print upon a record strip and an issued check. A portion of the record strip which is capable of being printed by the present machine is shown in Fig. 22 and Fig. 21 represents an issued check which is printed by the machine; it being noted that the line of data printed representing the item and other designations relating to the item entry in themachine is common for both the check and record strip and this common printing is effected by means of a sing'le set of type carriers which are differentially set by connections now to be described.

It is understood that the six banks of keys at the extreme left in Fig. 1 are capable of differentially setting their related segments I09 and these six segments I09 are shown in Fig. 10, which is a back view of the machine. Each of said segments I09 is in continuous mesh with a related pinion I25 carried by a related shaft I20, these shafts extending transversely of the machine and being also provided at their extremities with pinions I21. There is, of course, a series of six shafts I26 so as to communicate the differential movement of the operating segments I09 to the pinions I21. From Fig. 6 it will be seen that one of the pinions I21 shown in this view is in mesh with a segment I28 which is double in form in that it is provided with upper teeth I29 and lower teeth I30. A set of' six segments I28 is pro-'- vided as best shown in Fig. 10.

A corresponding form of connection (see Fig. 10) is provided for the seven operating segments I3I (which are similar to segments I09) related to the seven banks of keys at the right of the machine and these seven segments I3I have corresponding connections through shafts and pinions to a set of seven segments I32 which are shown in Fig. 10 and are similar in construction to the segments I28.

It will be understood that the upper teeth I29 of each of the segments I28 are adapted to set a corresponding type carrier and an example of such connection for one type carrier is shown in Fig. 9 wherein it will be seen that the teeth I29 are in mesh with a pinion I33 secured to a type wheel I34 having printing characters upon its periphery. In this manner, the six operating segments I28 and the seven operating segments I32 are adapted to adjust a set of thirteen type wheels to print upon a record strip and an issued check. Each of the aforementioned type wheels are provided with printing characters comprising the same indicia that are provided upon the key caps so that there may be printed upon the record strip and issued check the character designating the clerk operating the machine, which is printed in the extreme right hand column, and in the next six columns to the left the amount of the transaction is recorded in the English monetary system. The type wheels I34 controlled by the five banks of keys 22 carry type so as to print the member's account number and this is preferably printed in distinguishing characters upon the rec-. 0rd strip and issued check by small numerals, as shown in Figs. 21 and 22. The bank of transaction keys 28 causes the adjustment of a related type, wheel I34 so that the record strip, may be imprinted with alphabetical characters or abbreviations designating the type of transactionentered in the machine.

For the/ single bank of pence keys having eleven keys-I-9, I0 and II, as shown in Fig. 1, there is provided a type wheel I34 having eleven corresponding type, as shown by numerals on the type wheel I34 shown in Fig. 9. The two extra keys I0 and I are shown dotted in Fig. 2 and the extension H8 of the key designated H coacts with the stop extension H90, which prevents any appreciable movement of the slides I08, H0, and segments I09, and I28. The type II will thus be printed from. The extension H8 of the I0 key will coact with stop extension H910 to cause the movement of the related type wheel I34 one step to select the I0 type for printing.

For all the key banks having only keys I--9 the type wheels are blank in the first two positions but the type wheels are rotated two steps to select the 0 type in the absence of the depression of a key in that bank. In this case the stop extension H90 will engage an extension Bio of the bell crank 80 of the bank in which a key is not depressed; since in this instance the bell crank BI is notrocked. The keys I--9 of banks having such digit keys, or correspondingly positioned keys, control the differential movement of the type wheels 3-H steps, respectively to select the proper type for printing.

There will now be described the means for effecting the printing impression upon the issued check and upon the record strip contained in the machine, this being described in connection with Figs. 6, 9 and 12.

The record strip contained within the machine is designated in Figs. 6 and 9 by the reference numeral I35 and the record strip is drawn from a supply roll I36 and extends over a roller I31 (Fig. 9) thence over a roller I38 and to and around a roller I39, it being noted that this part of the record strip is directly beneath a platen I40. From the roller I39 the record strip extends upwardly and thence over a roller I to and around a roller I42, to a take-up roller I43. The take-up roller I43 is provided, as shown in Fig. 6, with a ratchet wheel I44 adapted to be engaged by a reciprocating pawl I45, the latter being connected at I46 to a bell crank I41. One arm of the bell crank I41 is forked to receive a stud I48 carried by a follower arm I49 (see Fig. 13) pivotally mounted at I50 and provided with follower rollers engaging complementary cams I5I secured to the drive shaft 29. The complementary cams I5I cause, at the initial operation of the machine, the rocking of the. bell crank I49 in a clockwise direction and the bell crank I41 in a counterclockwise direction thereby drawing the pawl I45 downwardly so as to engage the teeth of the ratchet wheel I44 and rotate the take-up roller I43 so as to feed the record strip the extent of one printing line. This feeding operation will space 1 the imprint next to be effected from the ceeding imprint if it has been made. After the s means may be provided. Such arrangements are common and well known in the art and for this reason'will not be described.

From Fig. 9, it will be seen that the inking ribbon I52 is disposed between the type wheels I34 and the portion of the record strip' between the rollers I38 and I39 so that when the platen I40 is depressed it will effect an impression upon.

the record strip. The platen I40 is adapted'to be reciprocated twice, once for effecting the printing upon the check paper in the manner to j be presently described, and the second time upon the record strip and this latter operation is adapted to occur as shown in the timing diagram in Fig. 24 in the period of the cycle designated as Record strip print during which time it will be seen that the type wheels I34 are also in stationary adjusted position.

The platen I40 is carried by a pair of arms I secured together by a tube I56 loosely overlying a shaft I51 (see Fig. 9). One of the arms I55 is provided with a rearward extension I58 (Figs.

. 6 and 12) provided with a pin I53 engaging a forked extension of an arm I60 pivoted at I8I. The rearward extension of the arm I60 is connected to an arm I62 by means of a link I63 and the arm I62 is secured to a rock shaft I64. To

the rock shaft I64 (Fig. 12) there is secured a follower arm I65 cooperating with complementary cams I66 secured to the drive shaft 23. By the above described connection between the platen carrying arms I55 and the comple-v mentary cams I66, the later will reciprocate the platen I40 twice during each machine operation,

and during the second reciprocation the platen I40 will force the record strip against the inking ribbon I52 so that the type wheels will effect a printing impression upon the record strip.

The check paper which is imprinted to form the check designated by reference numeral I1I series of idler gears I8I.

(Fig. 21) is drawn from a supply roll I12 and is led over a guide plate I13 and between an electro-roller I14 and a platen roller I15. The platen roller is carried by a spring pressed frame I16 (Figs. 6 and 9) and this frame is also provided with a resiliently urged inking roller I11 which inks the electro type carried by the electro roller I14. When the electro roller I14 is rotated it will feed the record strip and at the same time imprint upon the check paper the three lines of data designated by the reference numeral I18 (see Fig. 21).

Attached to the drive shaft 29 (Fig. 14) is a gear I13 adapted to drive a pinion I through 9. Attached to the gear I80 is a gear I82 which is in mesh with a gear I83 and the gear I83 has attached thereto a mutilated gear I84 and a supplemental mutilated gear I85. By the above described gear connec- .tions the gear I33 and mutilated gears I84 and I85 are given a complete rotation for each operation of the machine. The shaft I86 carryin the electro roller I 14 has secured thereto a pinion I81 (Fig. 14) which is adapted to be e gaged y sucthe teeth of the mutilated gear I84. teeth of themutilated gear I84 are disposed in 'an are designated A in Fig. 14 and are so disposed that at the initial operation of the machine,

the counterclockwise rotation of the mutilated gear I84 will cause its teeth to engage the pinion I81 thereby driving the electro roller I14 in the period of the operating cycle shown in the timing diagram in Fig. 24 and designated Check feed." This feeding of the check paper corresponding to the length of the checks occurs substantially during the time that the type wheels I34 are beingdiiferentially set ,during which time the check paper is fed so as to be disposed over the inking ribbon I 52 and beneath the record strip I35 so' that the first depression of the platen I40, in the manner previously described, will eiiect an imprint only upon the check paper.

After the imprinthas been effected, the printed check paper will be fed out of the machine be-- tween a pair of guide plates I88 and I89 (Fig. 9), it being noted that the check paper during the check feeding operation will be fed beneath a flattened portion of a check feeding roller I30 which is secured to a shaft I3I.

Referring to Fig. 14, the mutilated gear I85 is 'in the plane of an idler gear I32 which meshes with a pinion I33 secured to the shaft I 3I and the teeth of the mutilated gear I85 are provided in an are designated B in Fig. 14 and are so disposed as to engage the idler pinion I32 to rotate the pinion I33 and the shaft I9I during the operating period of the machine designated in the timing diagram as Eject.

When the check strip was fed during initial operation of the machine the leading portion was disposed beneath the flattened portion of the check feeding roller I90 and the resilient plate I89 so that the cooperation of thecircular periphery of the roller I30 with the resilient plate I89 will feed the check strip out of the machine and through an aperture I 34 (see Fig. 1) of the cabinet so that it may be grasped by the operator and withdrawn from the machine.

The machine is also provided with a cutting or severing device for severing the printed portion of the check paper from the remaining part of the roll and this is provided for by a movable knife I35 and a fixed knife blade I96 (see Fig. 9),

- it being noted that the check paper passes between these knife blades.

The movable knife blade I is carried by the forked ends of a pair of arms I31 (see Fig. 12) secured to a rock shaft I98 and to said rock shaft I98 there is secured an arm I33, it being noted that the stud I59 is also a pivotal connection between the arm I39 and the arm I60. By the above described operating means it will beseen that each time that the platen I40 is depressed the arm I39 will be rocked clockwise and the movable knife blade I35 will be depressed at the same time. It will be recalled that the platen is operated twice but during the first depression of theplaten the check strip will be severed by the movable blade I95 after which time the printed check will be ejected from the machine and out of cooperation with the movable knife blade I95 and the platen I40. The second depression of the platen I40 will' cause the printing upon the record strip, since at this time the check paper is entirely out of cooperation with the platen I40, and obviously during the second depression of the movable knife blade I35 no effective severing operation will take place.

Punching. mechanism The parts of the punching mechanism are primarily carried by a box-like frame comprising a bottom plate 201 (Fig. 16), a side plate 202, a

parallel side plate 203, and two end plates 204 singly from the top of the stack by means to be presently described. The plate 202 carries outside of the card receiving receptacle a pair of guide bars 201 (Figs. 16, 18 and 20) .and which are guide bars for rollers 208 carried by a plate 209, said plate 209 being provided with an integral transverse plate 210 to which is attached a bottom'support plate 2| I on which the stack of tabulating cards rests. In order that the stack of tabulating cards may be moved freely upward the bottom support plate 2| I is provided with rollers 212 (Fig. 18) rolling along the inside of the side plate 202. A spring 213 (Figs. 18 and 20) is con-- nected at one end to a stud 214 carried by the plate 209 and passes around a pulley 215 and the other end is attached to a fixed rod 216 and the tendency of the spring is to elevate the plate 209-210, and the bottom support plate 211 thereby continually urging the stack of tabulating cards upwardly so that the uppermost card frictionally engages the periphery of a feeding roller 211 (Fig. 18) which is secured to a shaft 218.

The driving shaft for operating most of the operating devices of the card punching mechanism is designated by reference numeral 219 (Figs. 18 and 20) and to said shaft there is connected a beveled gear 220 (Fig. 16) in mesh with the beveled gear 221 attached to the main drive shaft 29 whereby the drive shaft 219 of the punching mechanism is given a complete rotation for each machine cycle. To the shaft 219 there is connected a gear 222 (Fig. 20) in mesh with a pinion 223 attached to a larger gear 223a which is in mesh with a pinion 224 secured to a shaft 225. The pinion 224 is in mesh with a pinion 226 secured to a shaft 221. The pinion 226 drives a gear 228 through an idler pinion 229, and said gear 228 is secured to the shaft 218. Through the train of gears just described and shown in Fig. 20 the drive shaft 219 will rotate the shaft 218 thereby causing the roller 211, which is preferably formed of rubber, to rotate in a counterclockwise direction as shown in Fig. 18. By its frictional contact with the uppermost card it will feed said card to the right, as shown in Fig. 18, until said card is between the roller 211 and a roller 230 secured to the shaft 221. The'rollers 211 and 230 in cooperation with each other will feed the card further to the right until said card passes between a'roller 231 attached to the shaft 225 and spring urged rollers 232. The rollers 232, of which there is a pair, are each carried by a frame loosely pivoted upon the rod 233 and to the frame there is secured a spring 234 normally urging the roller 232 to contact the roller 231. The rollers 231' and 232 thereby feed the card to the right, as viewed in Fig. 18, until the leading edge of the card being fed passes between rollers 235 and spring urged rollers 236, the latter being arranged, constructed and supported similar to the rollers 232.

From Fig. 20 it will be seen that the gear 222 is in mesh with a pinion 231 secured to a gear 238 and said gear meshes with a pinion 239 attached to a shaft 240 to which rollers 235 (Fig. '18) are secured. The feeding of the card to theright, as viewed in Fig. 18, is terminated by means of a plate 241 which actsas a card stop and said plate is slidably mounted in a U-shaped support plate 242 and the plate 241 is apertured soas to receive a pair of arms 243 attached to a shaft 244. Attached to the drive shaft 219 is a cam plate 245 (Fig. 20) cooperating with a double arm 246 and the upper arm engages a stud 241 carried by one arm of a bell crank 240 secured to the shaft 244. The configuration of the cam 245 is arranged to rock the double arm 246 at the initial operation of the machine thereby rocking the bell crank 248 in a counterclockwise direction, andthe shaft 244 in the same direction, causing the plate 241 to be immediately depressed so asto be in the path of the card being fed. When the leading edge of the card, which is fed, abuts the stop plate 241 it will be entirely clear of the rollers .211 and 230 and 231232 but the card will still be in coaction with the cooperating rollers 235-436, and said rollers are still rotating to tend to feed the card further to the right by a frictional driving engagement but will be unable to feed the card due to the depressed position of the stop plate 241. The card is thereby held in a proper position for a punching operation to be effected by means to be later described. It will be observed that the roller 211 does not stop in its rotation during the operation of the punching mechanism of the machine, and if no means were provided the roller 211 would frictionally engage the card just beneath the one which is fed when the latter is fed clear of the roller 211. To prevent this operation, which would result in piling up of cards in the card punching mechanism, the following means is provided. Attached to a short stud 250 (Fig. 18) is an arm 251 carrying a stud 252 which is positioned in the card supply hopper so as to overlie the stack of tabulating cards to be fed. Attached to the stud 250 is a short arm 253 (Fig. 20) having a connection with a slidably mounted plate 254 which carries a roller 255 engaging a profile cam 256 secured to the drive shaft 219 of the punching machine. I

From the timing diagram, shown in Fig. 24, it will be seen that the cam 256 is so timed that after the roller 211 has frictionally fed a card so as to be firmly engaged with the roller 211 and the roller 230, the cam 258 will shift the slide 251 to the left 'Fig. 20) rocking the arm 253 and stud 250 in a'clockwise direction thereby causing the arm 251 to be depressed from the position shown in Fig. 18. The roller 252 will engage the card which is being fed forcing thestack of tabu- "lating cards downwardly and when the card which is being fed is clear of the roller 252, it will be seen that the roller 252 will now rest upon the upper surface of the card just below the one which is fed. The depression of the arm 251 will retain this card out of engagement with the roller 211 so that, even while the latter is still being rotated, it will not permit a second card feeding operation in the same machine operation. The cam 256 is arranged to retain the stack of tabulating cards depressed substantially during the rest of the machine operation after the time it is lowered. The tabulating card now having been fed to the proper punching position there will now be described the means for effecting the punching operation.

The punching mechanism is capable of punching the tabulating card, as shown in Fig. 23, so
