INVENT 8W fl ATTORNEY Patented Mar. 5, 1940 UNITED STATES CARD PUNcnrNG MACHINE Edward J. Von Pein, Endicott, N. Y., assignor to International Business Machines Corporation, New York, N. Y., a corporation of New York Application April 15,

8 Claims.

This case relates to machines for punching records such as tabulating or statistical cards.

The invention has for an object the prevention of repeat punching on a record by the punching a machine. This object, in relation to a machine in which the record is inserted by hand into punching position, involves the provision of means to compel the operator to remove a record after it has been punched and to insert a new record into punching position, before the next punching operation is permitted to take place. a The object, further, is to provide for the punching operation to be controlled by and to require insertion of a record into punching position.

The punching machine with which the present invention is concerned includes power means to effect the punching operation. In this connection, the invention contemplates the provision of a manual device effective to initiate operation of the power means only if the record to be punched is properly placed in punching position. Stated in another way, this object is to initiate punching operation under the joint control of a manual initiating device and of the record to be punched. It is proposed that this joint control he inefiective after the machine has punched the controlling record and to require a new controlling record to be inserted after each punching operation in order to enable the next punching operation to occur.

The power means for operating the punching mechanism is cyclically operated and the initia-.

tion of a' cycle is effected by operation of the previously mentioned manual device; provided, however; that a new record has been properly inserted into punching position.

It may be stated, as a broad object, that the invention shall provide, in a cyclically operating recording apparatus, means to manually initiate a cycle by operation of a manual device but shall prevent such cycle even though the manual device be operated, unless a new record has been inserted in recording position.

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.

Fig. 9 is a circuit diagram, and

Fig. 10 shows a portion of the card with the I columns which are adapted to be punched by the punching mechanism.

The record or tabulating card T- (Fig. 10) has parallel columns of index positions which may be selectively punched according to the well known Hollerith code to representdigits 0 to 9. The present machine is intended to punch a number into the first two columns only, the first column from the left being the tens denominational order column and the next or second column being the units order column, so that in Fig. 10 the punching of the two columns represents the number 79'. The machine for punching these card columns may be considered as divided into three main sections. Referring to Figs. 1 and 2 these three sections are: The actuating or power section A, the designation selecting section S, and the punching section P, all mounted on a base l0 and enclosed by a case ll. The punching section (also see Fig. 3) includes a sub-frame l2 carrying a pair of guidestuds l3 and M which pass through elongated slots of punch-carrying bars lliu and l5t to guide the punch bars for slidable movement in a horizontal direction. The punch-carrying bar I5u carries the means for punching the aforesaid units order column of card Twhile the bar I51.

carries the punching means for the tens order column. The punching means carried by each bar includesa single punch pin it mounted on the'carrying bar for vertical, slidable' movement, and a coacting die opening it. Between the punch pin l6 and the die opening Iii, the punch carrying bar is formed with a horizontally elon-' ated card slot l5 to receive the card to be punched by the depression of the punch pin. Securedto the sub-frame l2 are the legs of a generally U-shaped bracket is of which the base, or upper portion joining the legs, comprises a fiat plate portion I 8' constituting a card sup- .port or card bed. Fastened to the card bed [3 are angular side guides l9 formed with horizo'ntally extending portions to overhang the sides of the card resting on the card bed. The card bed l8 and guides 19 constitute a card chuteu ignation 25 are the two punch bars 15a and lSt, and the card chute is so disposed as to align the card supporting surface with the card slots 15' of the punch bars. Thus, the leading end of the card inserted by the operator into the card chute passes through the card slots l5 and engages the front stop ill]. The rear end of the card is aged with the back stop 18a, while the sides of the card abut the side angles Ill. The card chute thus holds the card in definite position with respect to the punch-carrying bars l5u and 151., with the long dimension of the card extending at right angles and the card columns extending in the same direction as the direction of movement of the punch-carrying bars. With the card in the chute, the first or tens order column lies in the card slots l5 of the punch bar let, while the second or units order column is located in the card slot of punch bar l5u. The card slots are of sufiicient length to permit the punch bars to move with respect to the card to any one of ten differential positions, each position corresponding to one of the ten designations, 0 to 9. With a punch bar in 0 position, its punching couple Iii-l6 is in line with the 6 index position of a card column; in the 1 position, the punching couple is in line with the l index position, and so on.

The positioning of the punch bars is controlled by the designation selecting section 5. The desselecting section includes a pair of stepped disks 25a and 25t, respectively corresponding to the units and tens order. There are eight series of steps 252a on the units order disk, each series having ten steps corresponding to the digits 0 to 9, as may be understood from Fig. 2. coextensive with each of the series of steps 25s, the tens order disk 25t has a single step 25t. Since there is one tens order step for each of the eight series of units ordersteps, there are eight tens order steps, corresponding to the digits 6 to 7 of the tens order. Both the units and tens order disk are rigidly mounted on a shaft 25. Also rigidly mounted on the shaft 26 is indicator dial 2'! bearing the numbers 0 to '79 corresponding to the eighty different positions in which the selector disks 25a and 25t may be set to control punching of the numbers 0 to 79. The indicator dial 2'! is formed with a notched periphery, there being one notch for each position thereof to coact with an impositive springoperated latch 28 to maintain. the assembly on shaft 26 in adjusted position. To adjust the shaft 28, the front end thereof projects externally of casing H and is provided with a hand knob 28. The tens order steps 25? are of progessively decreasing radial height, with the 0 step being of the greatest height and the 1 step being of the least height. The units order steps 25a of each series also progressively decrease in radial height with the 0 step being at the greatest radial distance or height and the 9 step being at the least radial distance. Since the two stepped disks move rigidly together, they may be considered as a selecting unit, each peripheral portion of which represents a diiferent two order value depending on the steps 25a and 25 C disposed within the peripheral portion. The periphery of the units order disk 25a is adapted to be engaged by a feeler 30a fastened to the front end of the units order punch carrier 1 511 and the tens order disk 25t is adapted to be en aged by a similar feeler 3th fastened to the front end of the tens order punch carrier 151i. The value of the selector steps in control positions, in front of feelers Elfin and t, is indicated by the number on dial 2'! exposed through the sight opening ill. In Fig. 2, the D of dial 2? is exposed, denoting that the ll step of the tens order disk is opposite the feeler of the tens order punch carrier and that ll step of the units order selector disk is in front of the feeler 38a of the units order punch carrier. To adjust the designation selecting means to control the punching of number 79 (see Fig. 50) the operator need only turn knob 2.3 one step clockwise to bring the number 79 into view at sight window 3|. This adjustment will position the l tens order step in front of the tens order feeler 3m. and will position the 9 units order step, of the series subtended by the l tens order step, in front of the units order feeler Elm. Similarly, by adjusting the dial 2! in either direction to bring any desired number into view at the sight window, a tens order step 2575' corresponding to the digit of the tens order of the selected number will be set in front of the tens order feeler Elli and a units order step 25u corresponding to the digit in the units order of the selected number will beset in front of the units orr er feeler 3531a.

In the normal, rear, idle positions of the punch bars 157: and u, their feelers Silt and u are at clearance distance from the locus of the 0 steps of selector disks 252i and a. The punch bars are held in their idle positions by a restoring lever the upper end of which has a stud 36 abutting the depending projectionst 'l of the punch bars. Springs 35 individually connected to the punch bars tend to advance them, but are unable to do so While the lever 35 is in its initial clockwise position (Fig. 2). Lever 35 is connected, through a link 39, with a follower arm ll! pivotally carried by a shaft and which has a roller 2 engaging a cam 43 on the cam shaft M (see 4). In the home position of shaft M. cam 43, by engagement with roller *2, holds the connected parts ll), 38 and 35 in normal positions, as indicated in 2 and 4. In the normal position of lever 35, its stud 3G maintains the punch bars in rear idle positions. During the one revolution cycle of shaft M cam l-J-l permits rocker arm 'll? to move clockwise, link 39 to move to the right and lever to move counterclockwise. These parts are actuated in these directions. when permitted by cam 53. under the influence of springs 38 acting through the punch bars. their projections 37. and stud 38 of lever 35. Consequently the punch bars lEt and u are advanced by springs to follow stud 3% until the feelerstllt and u engage the selector steps 251. and 23511. which are in control positions. Assuming. for example, that the selector disks are set in t position, then the ll tens and the 0 units step, of the series subtended by the El tens step,

are in control positions in front of their respeor".

tive feelers tilt and These steps will stop the advance of the punch bars when their feelers reach the ll selector steps in control positions. This extent of advance of the punch bars is such as to position their punch. pins !6 over the D index positions of the card columns.

'Thus, a punch bar will advance its maximum distance when'a' 9 step is in control position and will locate its punch pin !8 over the 9 index position. It may be understood from the above that the selector steps 8 to 9 control differential movement of the punch bars to locate their punch pins over the index positions of the card columns corresponding to the values ofthe steps in con trolled position.

After the punch bars have been arrested in differential, selected positions by the selector stepsso that their punch pins l8 are positioned to punch the card columnswith the'selected designationsthe punch pins are pressed through the card and into their coacting die openings It to punch the selected designations. The means for depressingthe punch pins I 8 includes a punch depressing baridfi (see Figs. 2 and 3) i which is carried by the cross piece of a bail-4i. pivoted on a shaft 48 carried by the subframe l2. Connected to one of the arms of the bail 4-1 is a link 49 pivoted to one end ofa bell-crank lever 59 which is connected at the other end to a link 5%. Link 5! (see also Fig. 5) is connected to a follower arm 5.? rotatably mounted on the aforementioned shaft 4! and which isprovided with a roller 5-: following the periphery of a cam 56 on the cam shaft M. During the cycle of shaft M,

cam 5 rocks arm :32 counterclockwise (Fig. 5)

is provided near oneend with a driven clutch disk 58 which pivotally carries the clutch pawl 51,

adapted to engage with a driving ratchet 58 rigid witha gear 59; Ratchet wheel 58 and gear 59 are rotatably carriedbyshaft 4'4, and the gear is meshed with a gear 68 driven by a pinion El 'on the shaft 82 extending from the gear reduction. box 83 in which is the gearing (not shown) driven by the motor M. The clutch pawl .57 is normally held disengaged from the teeth of ratchet 58 by engagement of the rear ortail end of the pawl with a. fixed stud 84. In order to initiate a cycle of camshaft 44, the operator depresses the key 65 (see Figs. 1, 2 and 6). The lower end of key 85 has a stud 66 engagedwith'the butt end of a rocker arm 8'! which is connected to a spring 68. The spring 63 acts through the arm 81 to maintain the key 95 in normal raised position. Connected to arm 61 by link 89 is an arm 19 fastened to a shaft H to which is fast an upright arm 12. Arm. 12 has a pin 13 engaging the lower edge of a pawl 14 which is pivotally carried by arm 12 by means of a stud 15 (also see Fig. 7). A spring 18 between the pawl M and arm l2 'yieldably maintains the lower edge of pawl M engaged with pin 13. The nose of pawl 14 is latched over the horizontally bent tab ll formed at the upper end of a lever 18. The tab .1? initially abuts the top of a projection 89 of a disk 8| fastened to cam shaft M. Upon depression of key 85, the stud and the pawl nose through its engagement with tab ll rocks the lever '58 clockwise (Fig. '7) against resistance of a spring 82. As a result, the tab l! leaves the projecting lug 89 of disk 8i.

A lever'83 has a roller 84 at its free end (see Fig 1) coacting with the inclined edge of a cam disk 85 on cam shaft 44. A spring 86 connected to lever 83'urges the lever downwardly, causing its to engage a tooth of the driving ratchet 58.-

Fuither, the front of lug 88 of disk 8| has moved in front of the tab Tl temporarily to prevent return movement of the lever 'l8. Still further, the high portion of cam 88 (Fig. 6) on the cam shaft has moved away'from the lower end of a latch 89, permitting a spring 9|] connected to the latch to rock its nose above the shoulder 9! of the key slide 85 so as to maintain the key slide in its manually depressed position until a cycle of shaft 44 has been completed. The pivot 92 of leverl'8 is carried by an intermediate portion of a lever 93 which is freely mounted'on the aforementioned shaft H. When the lever 18 is in its normal position, with its tab 1! engaged by the stop of lug 89 of disk 8|, the-n the carrier lever 93 is thereby maintained in upper position.

When the lever 18 is released from lug 80, a

spring 94 (Fig. 6) connected to carrier lever 98 is permitted to rock the latter lever downwardly I causing an insulating stud 95 thereof to depress the upper spring contact blade 96 of 'a normally open switch 9'! so as to close the switch. Switch 8'! is in. the motor circuit, but its closure is not sufficient of'itself to'complete the motor circuit. In order to complete the motor circuit, it is necessary that a cardT be properly insertedin the card chute l8'--l9 to close contacts 98 in series with switch 91 (see Fig. 9). Figs." Band 8, contacts'98 are carried by spring blades 99 and I88 fastened through insulation" to the subframe 12 of the punch'section. Spring blade 99 engages a roller llll, of insulatingmaterial, which is carried by the ear l9! of a member '32. The member 192 is formed with a vertically elongated slot 92 through which a fixed pin l83pa'sses. A spring IM betWeen pin I93 and pin m5 of member I92, urges the member downwardly, while the spring leaf 99 abuts roller I9! to urge the member I82 in a clockwisedirection about the pin I93. In the normal, lowered, clockwise position of member I82, maintained by springs 99 and Hit, the front edge 32a ofthe member extends completely across the depth of the card slots I 5' of the punch bars I511. and t. In this'position of member 182, when a card T is inserted in the chute, the leading edge of the card engages the edge lliZa and forces the member I92 rearwardly-to close switch 98, as indicated in Fig. 3. Referring to Fig. 9, when both the switch 97 of the actuating section A and the contacts 98 of the punching section P have been closed, in the manner described above, a circuit is completed through motor M as follows: From the side of the supply line, through a magnet Hll, contacts 98, motor M, switch 91, andto the side of the line. This circuit energizes magnet I 81 to close contact Mild, b-y-passing contacts 98. The motor circuit will now remain closed,

, as long as switch 91 is closed. The opening of switch 9? occurs at the end of the cycle as'disk- 8! of the cam shaft moves to home position and its lug 80 engages tab 'H'to raise lever ill-and thereby to raise the switch-operating lever 93.

Referring to tion by the lug BI Of'disk 8|.

"Ihe motor, having been set in operation, the driving ratchet 58 is now rotated and, through the clutch dog 51, already engaged therewith, imparts rotation to cam shaft 44'. During rotation of the cam shaft, cam 43 causes the punches it to be set in differential positions determined by the selector disks. After this occurs, the cam 54 (Fig. 5) rocks follower arm 52 counterclockwise which, through link 5|, rocks bell crank lever 5 clockwise (Fig. 2) to lower the link 35 causing bar 46 to depress the punches It to perforate the card columns with the selected designations. The return half of cam 54 has a low point-54a (see Fig. 5) which permits the fol lower roller '53 to move further inward than its home position. When the follower roller 53 is engaged with low point Me, the link 49 of the punch operating means is raised above its home position. On link 59 is a pin I08 which is below the ear I! of member I02. Below the card-engaging front edge 902a of member I02, the member is recessed to provide an angular notch I022) which normally lies below the level of'the card slots I, as indicated in Fig. 3. When link 49 rises above its normal return position, the pin I08 thereof strikes ear lBI of member I02 to raise the member bodily until its front edge I02rz and the top of its notch I021) rise above the level of the card T in the card chute. As soon as the front edge I02a of member I 02 rises above the card surface, the member is free to rock clock wise under the influence of spring contact blade 99 until the side of notch I021) abuts the card edge, as seen in Fig. 8, meanwhile permitting contacts 98 to open.

As the cam shaft 44 completes its one-revolution cycle, the tail of clutch dog 51 rides under the fixed pin t4 (Figs. 1 and 6) which cams the nose of the clutch dog out of engagement with driving ratchet 53 (Fig. 6). Cam 88 acts to release latch 80 from key slide 65 which thereupon rises under the influence of spring 68 acting through pivoted arm 51. The return of arm 61. brings parts 'I0,,'i2, and 14 back to normal positions, enabling the nose of part M (Fig. '7) to reengage the tab TI of lever I8, which has meanwhile been returned to upper, normal posi- As the lever 18 moved upwardly, it carried lever 93 with it, causing switch 97 to open and break the holding circuit of motor M. Magnet I 01 (Fig. 9) drops its contacts Idle, and the motor circuit cannot be reestablished unless both switches 91 and 98 are again closed. The actuating section A is then in starting condition.

If the operator permits the card T to remain in the card chute after it has been punched during the cycle of operations just completed. the following depression of key 65 is ineffective to start a new cycle of operations. This is because contacts 08 (Fig. 8), which have been opened, cannot be'closed again by member I02 which now has the top of its notch I021) sitting on the card. The card cannot be moved further to the right (Fig. 8) because its leading edge is stopped by the frame lug 20 and, therefore, the member I52 cannot be moved counterclockwise to close contacts 5-38, the closure of which is required, in conjunction with the closure of switch S1, to complete the motor circuit and start a new cycle of operations. In order to start a new cycle, the operator must remove the old card from the chute and then insert a card again in the chute. The removal of the old card permits spring Ifi l to lower the member I02, positioning its edge I02a completely across the depth ofthe card slot I5 and its angular notch I02b below the card supporting surface of card bed I8. Now, upon insertion of the next card, the leading edge thereof strikes the edge I02a of member I02 to move the member rearwardly for closing the switch 98. With switch 98 closed by insertion of a new card and switch 9! closed as a result of depression of key 65, the motor circuit is again established to effect a new cycle of operations.

While there has been shown and describedand pointed out the fundamental novel features of the invention as applied to a single embodiment, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
