(01. 164-113) This invention relates to recording apparatus, and. more particularly to amapparatus for inscribing information in statistical cards for use in tabulating systems.

It is an object of the present invention to provide a simple and economically constructed recording machine capableof operation at a high rate of speed.

In accordance with one embodiment, the invention contemplates the provision of a perforating apparatus for inscribing information in statistical record sheets wherein a group of keys having numbers corresponding to the value of the perforations in each row or column of a statistical record card is provided for setting up information to be perforated in the card. These keys are adapted to store information in a plurality of groups of relays and each key upon being operated automatically associates the entire group of keys with a' succeeding group of relays.

There is provided one group of relays for each column of the record card and each group consists of a relay for each possible hole in that column. After the keys have been operated a number of times corresponding to the number of columns of the record card, a punch controlling key may be actuated and the information stored in the relays Means is also provided for setting up information in the device which will automatically be perforated in all succeeding cards until said means is rendered ineffective manually.

This

sired to have perforated, thereby providing flexibility of operation.

Fig. 10 is a circuit diagram showing schematically the electrical connections between the various parts of the apparatus;

Fig. 11 is an enlarged plan view of a combined alphabetical and numerical keyboard, a portion of which appearsin Fig. 1 and which may be used when it is desired to perforate combinations of perforations in a row or rows of astatistical card to represent printed matter, and 40 Fig. 12 is a circuit schematic of the electrical connections running from the keys shown in Fig. 11 and when placed to the right of Fig. 10 with the lower portion of Fig. 12 adjacent the upper'portion of Fig. 10 and when considered in from the top of which extend I5 keys having imprinted thereon reference characters indicating the particular function of the keys. These keys are designated P, S, BS and 8, I, 2, 3, 4, 5, 6, I, 8, 8, II and I2. The keys I to 8, 8, II and I2 are all exactly the same in construction and each of them upon being operated, will close an electrical circuit between three contacts individual thereto. The keys having the characters P, S, I2, II, 8, I, 2 and 3 control the operation of contact springs mounted upon the right side (Fig. 8) of the key box I2 and thekeys having the characters BS, 4, 5, 6, 1, 8 and 9 control the operation of contact springs mounted on the left side (Fig. 8) of the key box I2. Since the construction and operation of all of the keys bearing numerals are exactly the same, only one of them will be described, namely the key associated with the numeral I2 which has been assigned reference numeral I3, and is shown in full in Fig. 8 positioned at the right of the figure. The key comprises a button I4, having a stud I5 fixed thereto which is slidable in an aperture I6 formed in a top plate I1 of the key box I 2. The lower end of the key I3 is slidably positioned in an intermediate plate I8 and has a pin I 8 extending through it which normally engages the underside of the intermediate plate I8 to prevent upward movement of the key beyond a predetermined position, a spring 28 being positioned between the button and the top plate I1 and surrounding the stud I5 for normally urging the key upwardly. The stud I5 has formed integral therewith a laterally extending contact actuating lug 26 which, upon depression of the key, will engage a contact spring 21 suitably mounted in an insulating block 28 to complete an electrical circuit between the spring 21 and a pair of cooperating contact springs 29 and 38, for controlling the operation of the mechanism. The key I3 is provided with a reduced portion 3| which normally enters an aperture 32 in a shiftable plate 33 slidably mounted in the key box I2. The shiftable plate 33.is normally urged to the left (Fig. 8) by a contractile spring 34, through a link 35 fixed to 9. lug 36 extending downwardly from the plate 33. However, under circumstances to be described hereinafter, plate 33 may be moved to the right (Fig. 8) due to the energiza- .tion of an electromagnet 31, armature 38 of which is pivotally secured to the link 35, and will prevent the depression of the key I3 due to the moving of the aperture of the shiftable plate 33 out of registration with the reduced portion 3| of the key.

As pointed out hereinbefore, all of the keys are constructed in exactlythe same manner and the shiftable plate 33 is common" to all of the keys except the keys indicated by the letters P, S and BS which do not have the reduced portion 3I and which, upon their operation actuate only one electrical contact spring for completing an electrical circuit between itself and another contact spring mounted in a manner similar to the contact springs associated with the key I3 which has been described in detail. From the foregoing, it will be apparent that when the electromagnet 31 is energized, none of the keys bearing numerals can be depressed. The purpose of this arrangement will become apparent as the description progresses.

The keys in the key box I2 associated with the numbers and letters I2, II, 8, I, 2, 3, 4, 5, 6, 1, 8, 9, P, S, BS, have been assigned the reference numerals I3 and 43 to 56, respectively.

Referring to Fig. 10, it will be seen that the right hand contacts of keys I3, 43, 44, 45, 46, 41, 48, 48, 58, 5|, 52, 53 and 56 are connected through conductors 51,- 59, GI, 63, 65, 61, 69, II, l3, I5,

' ductor 83 to one side of the winding of an 'elec- 10 tromagnet 84. The left hand contacts of keys I3 and 43 to 53, inclusive, 55 and 56 are connected through a conductor to ground at 86. The purpose of these circuit connections will become apparent as the description progresses. l5 The brushes 58, 68, 62, 64, 66, 68, 18, 12, 14, 16, 18, 88 and 82 together with a brush I88 (Figs. 1, 4 and 10) are mounted upon a cross bar ml of insulating material forming a part of a relay distributor carriage I82 comprising thecross bar 20 and a bracket I83. Rotatably mounted in each end of the bracket I83 (Fig. 4) is a pair of grooved rollers I84 and I85 which ride upon two tracks I86 and I81 extending upwardly from brackets I88 and I89, respectively, mounted upon plate 25 supporting side members H8 and III, respectively, extending upwardly from the base II. A pair of small U-shaped brackets H8 and H8 are provided normally to hold the grooved rollers I84 and I85 in place upon the tracks I86 and I81. 30

From the foregoing it will be apparent that the carriage I82 may be moved to the right or left (Fig. 1) on the tracks I86 and I81 to move the brushes 58, 68, 62, 64, 66, 68, 18, 12, 14, 16, 18, 88, 82 and I88, in unison over a contact plate I28 35 mounted on the plate supporting side members H8 and III.

The embodiment of the machine being described in detail is of the type adapted to perforate a record card having 45 columns of 12 holes each 40' it being understood, however, that by simply increasing the number of the various parts of the apparatus hereinbefore described and to be'described hereinafter, a card having any desired number of columns and any desired number of 45' possible perforations per column, could be perforated. Since a perforating mechanism adapted to perforate a 45 column card has been selected for illustration, the plate I28 which is formed of insulating material has embedded therein 45 50 columns of contact pins I2I there being a pin in each column for cooperation with each of the brushes 58, 68, 62, 64, 66, 63, 18, 12, 14, 16, 16, 38, 82 and I88 and the brushes, in being moved in unison across the contact plate I28 will engage the 55 contact pins I2I associated therewith.

A driving bar I22 (Figs. 2, 4 and 7) is secured to a downwardly extending portion of the bracket I83 and upon being actuated by mechanism hereinafter described, will advance the relay distribu- B0 tor carriage I82 step-by-step across the contact plate I28 to bring the brushes supported thereby successively into engagement with all of the contact pins I2I associated therewith.

Referring now to Fig.,10, it will be seen that .eachof the contact pins I2I with the exception of open-s11.

pointed-out hereinbefore, one associated with each contact'I2I on the contact plate I22, except the strips of-insulating material I22 for connectionto other parts of the apparatus and the plates I21 horizontal rows of contacts I2I associated with the brushes 22 and I22. Extending upwardly from the sub-base plate I22 are a plurality of metallic bars I22 which support the relays. The relays I22 are mounted on either side of the metallic bar I22 and are arranged in rows along the sides of the bar so that some of the parts which make up the separate relays are common to two of therelays directly opposite each other on the bar I22.

Since there are 45 columns of contacts on the contact plate I22, there will be"45 columns of re-' lays supported upon 23 metallic bars I22. For the sake of simplifying the disclosure, only two rows of relays will be des ribed.

Mounted upon opposite sides of the metallic bar I22 is a pair of platgs I21 extending the length of bar I22 which have upwardly extending projections I22. There are two projections for each relay and since there are I2 relays in each of the 22 columns, there willbe 24 projections I22formed on the plate I21, one of which will act as the core of the relay winding and the fixed contact of the engagement with the fixed contacts on the projections I22 upon energization of a winding (I20 of the relay. The windings I22 are insulated from the bars I22 by sheets of insulating material I2I I and m which are suitably apertured to permit I the positioning thereof upon the upwardly extending projections I22 of the plates I21. The T-shaped contact members I22 are provided with terminals I22 at theirlower extremities whereby they may be connected in the electrical circuit, anduponenergization of any relay winding I22 the movable contact member I22 will be attracted to complete a circuit from the movable contact member I22 through the projection I22 which serves as a cor of the relay,'and through the plate I21tothe bar I22. Insulated conductors I22 and magnet 22 of'an'y-keyinthe keybox I2 willheenergiaeth" Energization of the magnet 22 will attract its armature II to which there isattached a link I21;

the other end of which is pivoted to a T-shaped -is lever I22. The electro-magnet 22 is mounted on a depending portion I22 of the track- I21, and its armature I22 is also pivoted to this' portion of the track as shown in Fig. 2. The T-shaped lever I22 is normally urged to the right (Fig. 2)- about a pivot pin I22 secured to'the track I21 by a coil spring I22 secured to a second downwardly extending portion I2I of the track IIII. Also oscillatable about the pivot pin I22, is an escapement cam I22 having a pin I22 secured thereto and 12' extending into an. aperture I22 in the T-shaped' lever I 22. A coil spring I22 secured to a down wardly extending portion of the escapement cam I22 normally urges the cam in a counterclockwise direction into engagement 'with notches I21 "formed on the underside of the driving bar I22 which isnormally urged to the left (Fig. 2) by aspiral spring I22 secured to the right end of the driving bar I22 at I22. The spiral spring 122 is enclosed in a housing I12 and is mounted upon 22 a bracket "I, the support for which will be described hereinafter. The left arm (Fig. 2) of the T-shaped lever I22 has a slot I11 formed therein in which a pin I12 secured-to an oscillatable stop.

member I12 is slidable, the oscillatable stop member I12 being pinned to the track I21 11.17122.-v A pair of contact springs I2I and I22 are lasso-F ciated with the stop member I12 and when the I stop member is in normal position as shown in Fig.

2, contact will be made between the contact 25 'At the same time stop-member I12-will be moved 22 I22 are connected to opposite ends of the windings I22 at the lower'sheet I22 of insulating material and passed through apertures I21 in the are connected to ground at I22 (Fig. 10). The conductors I22 connect one side of the winding of each of the relaysjfl 'ig. 10) to the contacts I2I associated therewith, and theconductors I22 are connected to a common conductor I22 (Fig. 10).

taneously'connect ground through the conductor 22 tonne side 'ofi the winding of the electromagnet 22 (Figs. 2 and 10) the other side of the winding of which is connected through conductors [22 .and m to a fixed contact I22 which will be en- 'gaged by a movable contact I22 while information is being put into the machine due to the op-- eration of a part of the mechanism to be described hereinafter and since the movable contact I22 is a connected to grounded battery at I 22 the electroup into one of the notches I21 to prevent the driving bar I22 'from moving until the 'key ,op-i erated is released. As the stop a member I12 moves upwardly it will break the electrical cir-:. cult between 'the contacts Ill and I22. i Whenthe key which. has been operated is released, the electromagnet will be deenergized and the driving bar I22 will be permitted to move one step to the left due to the fact that the stop. member I12 will be removed from the notch with which it is associated just .before the edge of the pawl I22 passes the lower edge of the notches I21 to enter the notch adjoining the one from which it was removed upon ener'gization of the electromagnet 22. .6 In order to permit the operation of the driving bar I22 in a reverse direction in the .event that a' wrong number has been set up on the keys bear ing numerals, the back space key is provided. This key differs from the other keys in'the group in that it is connected a flexible connection I22 commonly known asa-Bowden W e L back space pawl I22 to move the pawl in "a-f counterclockwise direction around a pivot' pin I22, upon which it is pivoted, which pin is-se- 7 cured to an oscillatable lever I 21 which is"nor-" mally urged in a counterclockwise direction about" a pivot I22 by a spring I22. Upon-the depression of the back space key 22 the flexible connection which is connected directly hereto, will first ro- 22"- tate the back space pawl I95 about its pivot I95, and continued downward movement of the key will force the oscillatable lever I91 in a clockwise direction about its pivot I99 to step the actuating bar to the right (Fig. 2) one notch.

Each time a numeral bearing key in the key box I2 is operated, it will be apparent from the description thus far that the relay distributor carriage I02 will be stepped one space to the left (Figs. 1 and 2) after energizing a relay I29 associated with the key operated through one of the contacts I2I and the brush associated with the particular key actuated. Thus, upon the keys in the key box I2 being actuated manually, the relay distributor carriage will step across the face of the contact plate I20 energizing the relays associated with the keys operated in all of the columns until the keys have been operated 45 times (this being the number of holes which it is desired to perforate in the card) when the relay distributor carriage will have passed over all of the columns of contacts to store in the relays the information which it is desired to per-' forate into a record card. From the description of the circuit connections, it will be apparent that when the space key 55 is operated the electromagnet 94 will be energized to advance the relay distributor carriage I02 one space without storing any information in the relays I29 associated with the row of contacts I2I with which the brushes of the relay distributor are at that time associated since the space key is not connected to any of the brushes associated with the contacts I2I.

Movable with the relay distributor carriage I02 and mounted upon the extreme left end of the driving bar I22 (Figs. 1 and,2) is a contact operating mechanism I95 which comprises a plunger I99 slidable in an aperture I91 formed in a block I99 and engaging the lower end (Fig. 1,) of a lever I99 pivoted intermediate its ends upon a pin 200 mounted in the driving bar I22. The lever I99 carries at its rear end (Fig. l) a contact operating roller 20I for engaging a group of contacts designated generally by the numeral 202 (Figs. 1 and 10) in such a manner as to cause a contact 209 to engage a contact 204 when the lever I99 is moved in a counterclockwise direction (Fig. 1), to overcome the resiliency of the contact spring 209. The contact operating mechanism I95 moves with the relay distributor carriage I02 and upon the relay distributor carriage reaching its extreme left position, the plunger I95 will engage an abutment 201 on a punch distributor carriage 209, whereupon the lever I99 will be rocked upon its pivot to move the contact 209 into engagement with its associated contact 204 (Fig. 10). A portion of the relay carriage I02 together with the contact operating mechanism I95 is shown in dotted lines in Fig. 1 in the extreme left position of the relay distributor carriage I02.

The punch distributor carriage 209 as shown in Figs. 1, 3 and 4, comprises a bracket 209 carrying at its ends grooved rollers 2H and 2I2. The rollers 2i I and 2 I2 are mounted upon the bracket 209 in the same manner that the rollers I04 and I05 are mounted upon the bracket I09, and the roller 2 travels upon the track I05 together with the roller I04, whereas the roller 2I2 travels upon a track 2I9 the construction of which is exactly the same as that of the track I01, a U- shaped bracket 2 being provided to maintain the roller 2I2 in position upon the track 2I9. A

punch distributor driving bar 2291s provided for movingthe punch distributor carriage 209 to the right orthe left in a manner similar to the movements of the relay distributor carriage I02 for moving a set of brushes-'2 over the contacts 5 I2I to take the information stored in the relays associated with the contacts I21 therefrom and control the operation of a punching mechanism in accordance with that information. i

The plunger I95 and the abutment 201 are so 10 positioned that when the brushes on the relay distributor carriage I02 and the brushes on the punch distributor carriage are in a position upon the contact plate I 20 where they are spaced apart less thanv the distance between two rows of con- 15 tacts Hi, the plunger I99 will be actuated to move the contact 209 into engagement with the contact 204.

The driving bar 220 for actuating the punch distributor carriage 209 is provided, as shown in 2 Figs. 1 and 3, with teeth 222 upon its upper surface and 'notches 229 upon its lower surface and supports, adjacent its right end Fig. 3, the bracket I1I upon which is mounted the spiral spring I59 (Figs. 2, 3, and 7). surface of the punch distributor driving bar mesh 1 with a gear 224 for driving the punch distributor driving bar to the right (Figs. 1 and 3), a spring motor 225 of a well known type being provided for normally tending to drive the punch distribu 3o tor driving bar to the right. The spring motor 225 is mounted upon a side plate 225 of the punch mechanism which is indicated generally in Figs. 1 and 4 by the numeral 221.

The punching mechanism 221 comprises a 35 group of I2 perforating pins 295 (Figs. 1, 4 and 5) mounted in guide plates 295 and 291 secured between side plates 299 and 299. The perfoiating pins 295 are slidable vertically in the guide plates 299 and 291 and each pin has associated 4o therewith an interposer bar 240 which has its left end (Fig. 5) supported on the head of the perforating pin and its right end slidable in a cross member I mounted between the side plates 299 and 299, the interposer bars being provided with pins 242 to prevent movement thereof in a horizontal plane beyond a predetermined distance, and the cross member 2 being slotted at 249 so that it will support the interposer bars 240 but will permit a slight rocking movement thereof. Mounted upon suitable supports 244 extending between the side plates 299 and 299 and arranged in staggered relation are a plurality of electromagnets 245, (Figs. 1, 5, 6 and 10) one of which is associated with each of the interposer bars 240. Each of the interposer bars 240 is provided with a lug 240 adapted to enter an aperture in an armature 241 of its associated electromagnet 245,

so that upon energization of the electromagnet 245 associated with any interposer bar, that bar on will be released for movement to the left (Fig. 5) the bars as shown in Figs. 1 and 5 being in their normal or extreme right hand position.

Each of the interposer bars 240 has a notch 259 out in the left end thereof (Fig. 5) to permit the A ,5 downward movement of a punch actuating ram 254 without operating the perforator pin 295 associated withthe interposer bar 240 when the associated therewith to move the interposer bar into position to be driven downwardly by the 7 The teeth 222 on the upper 25 cessive keys in the key box as shown in Figs.

However, the spring has its inner end secured to a shaft 258 and will tend to resiliently drive the bar to the right or the left with the shaft 258 which at predetermined points in the cycle of operation of the punch is rotated in opposite directions (see Fig. 6).

In Figs. 1, and 6 there are shown the cams for operating the punch actuating ram 254 and the shaft 258. The ram 254 is common to all of the perforating pins 235 and their interposer bars 248 and extends across the space enclosed by the side plates 238 and 239 to which it is pivoted as shown at 251 (Fig.5) and is operated by a link 258 pivoted to the right end of the ram and having its other end pivoted to an oscillatable cam lever 259.

The shaft 28! carries a second cam 218 (Fig. 6) having a cam groove 21! formed therein in which rides a cam roller 212 positioned upon the end of a cam lever 213 .pinnedto the shaft 256. The cam grooves 263 (Fig. 5) and 2'11 (Fig. 6) are so formed that their associated cam levers will be moved through the following cycle each time the shaft 28! is rotated. Simultaneously, the cam lever 213 will be rocked in an anti-clockwise direction to store energy in the springs 255 tending to advance the interposer bars 248 to the left, and one of the electromagnets 245 actuated, the interposer bar 248 associated with that particular electromagnet will be advanced to the left by its spring 255, and shortly after the arrival of one of the interposer bars over its associated punch, the cam 262 will actuate the cam lever 259 to drive the punch actuating ram 254 downwardly and then upwardly. After the punch actuating ram 254 reaches its uppermost position the shaft 256 will be rocked by the mm 218 in a clockwise direction and any interposer bar which has been advanced to the left will be retracted to the position shown in Fig. 5..

Secured to the underside of the ram 254 is a perforator pin stripping plate 218 which moves with the ram and will retract any perforating pin, which has been driven downwardly, back to its normal position as shown in Fig. 5 when the ram is elevated.

After all of the information to be perforated in a record card has been set up by operating suc- !2, the punch key 54 may be operated to cause the brushes 22! on the punch distributor carriage 288 to be associated with the contacts !2! for controlling the operation of the electromagnets 245. The operation of the punch key 54 (Fig. 10) will connect ground at 219 through the contacts of the key, a conductor 288 (Fig. 10) to one side of the windings of an electromagnet 28 I ,7 the other side of the winding of which is connected to grounded battery at 282, and from the conductor 28!) through a branch conductor 283 to a front contact 284 and to one side of the winding of a relay 285, the other side of the windings of which are connected to grounded battery at !54. The electromagnet 28! 3 and 10 will attract its armature 286 which has pivoted thereto a link 281. The electromagnet 28! is mounted upon a depending portion 292 of the track 2 l3, and the link tractlle spring 293, one end of which is secured cam lever 259 may be' 281 is normally urged to the left (Fig. 3) by a conto the depending portion 292, and the other end of which is fixed to a projection 294 formed on the. link 281.

An escapement mechanism comprising a pair of pawls 295 and 296 is provided for advancing the 5- punoh distributor driving bar 228 to move the punch distributor carriage 288 across the face of the contact plate I28. The pawl 295 is pivoted on the depending portion 292 of track 2 !3 at 291 and is normally urged about its pivot in a clockwise my direction by a contractile spring 298, and the pawl 296 is pivoted on an oscillating lever 299 at 388 in the manner shown in Figs. 3 and 9, the pawl 296 being normally urged to rotate about its pivot in a clockwise direction by a contractile spring 38!. The pawls 295 and 298 are provided with cam slots 382 and 383 adapted to be engaged by cam ming pins 384 and 385 mounted upon cam levers 381 and 388, respectively. The cam levers 381 and 388 arepivoted upon small stud shafts 389 and 3l8 secured in the depending portion 292 and are pivoted at their lower end to pivot pins 3!! and 3l2, respectively, on the link 281, so that when the electromagnet 28! is energized to attract its armature 286, the camming levers 381 and 388 will be rocked about their pivots 389 and 3!8, respectively, to cam the pawls 295 and 296 out of engageme t with the punch distributor driving bar 228 to permit it to be driven to the right by the spring motor 225. 30 The oscillating lever 299 (Figs. 3 and 9) is pinned to a stud shaft 3l3 journaled in the depending portion 292 of the track 2!3 and the shaft 3!3 has pinned to the opposite end thereof a cam vlever 3!4 carryinga cam roller 3!5 adapted to be driven by a cam 3!6 keyed'to the shaft 28!.

The punch distributor driving bar 228 has a pin 32! positioned thereon which, when the punch distributor driving bar is moved to its normal position as shown in Figs. 1 and 3 will engage a slide bar 322, slidably mounted upon supporting pins 323 positioned upon plates 324 supported by the track 2!3, and will move the slide bar to the position shown. The slide bar when moved to the .position shown in Fig. 3 will be maintained in that position by a spring pressed center stop 325', mounted on the left hand plate 324', engaging a notch 328 in the lower edge of the slide bar.

When the electromagnet 28! is energized to permit the spring motor 225 to drive the punch distributor driving bar 228 to the right, (Fig. 3) the slide bar 322 will remain in the position shown untillthe driving bar nears the end of its travel to the right, at which time the pin 32! will engage an arm 321 of the slide bar to shift the bar to a position where the center stop 325 will engage a notch 328 to hold the bar stationary until it is engaged by the pin 32! near the end of the travel of the pin to the left (Fig. 3). r

The slide bar 322 carries a pair of pins 329 and 338 of insulating material, which when the slide bar is moved to the right engage contact springs 33! and 332, respectively, to move them to the right and to cause the spring 33! to engage a cooperating contact spring 333 and to cause the spring 332 to disengage from a cooperating con tact spring 335. The contact springs 33! and 333 are mounted in a block 334 of insulating material positioned on a downwardly'extending portion of the track 2 l3 and the contact springs 332 and 335 are positioned in a second block 338 of insulating material also mounted on a portion of the track 2 3.

The contact springs 33! and 333 are normally out of engagement and the contact springs 332 the contacts-35l and I the electromagnet and 335 are normally in engagement with each other so that when the slide bar 322 is moved to its right hand position (Fig. 3) a circuit will be made between contacts 33I and 333 and a circuit will be broken between contacts 332 and 335. When the slide bar is in its left hand or normal position, the contacts 332 and 335 will connect ground at 331 to a back contact 339 of relay 285. Thus when 28I is momentarily energized, the relay 285 will also be energized and the punch distributor driving bar right due to the completion of the locking circuit of relay 285 through back contact 339 until contact springs 332 and 335 are disengaged at the end. of the travel of the driving bar to the right (Fig. 3) at which time the pin 321 will engage the arm 321 to shift the slide bar 322 to the right and break the locking circuit by moving the contact spring 332 out of engagement with contact spring 335.

Simultaneously with the breaking of the locking circuit to the electromagnet 28I, the contact spring 33I will be moved into engagement with contact spring 333 which is connected to one side of a motor 356 which drives the shaft 26 I. The other side of the motor 356 is connected to one side of a current supply line through a conductor 351 and the contact spring 33I is connected through a conductor 358 to the other side of the current supply line.

A contact actuating pin 348 is mounted upon the punch distributor driving bar 228 in a'position where it will not engage the upwardly extending portions of the slide bar 322, but when the driving bar 228 is moved to its extreme right hand position (Fig. 3) the pin 348 will assume the position shown in dotted lines (Fig. 3) where it will engage a pivoted lever 349, pivoted to the track 2 I3 at 358 and normally held in its upward position by the tension of contact springs 351 and 352 (Figs. 3 and 10).

The contact springs 35I and 352 are mounted in a block 353 of insulating material and are normally out of engagement with their cooperating contact springs 354 and 355, respectively, also positioned in the insulating block 353 which is secured to thetrack'2l3. The pivot lever 349 is so formed (Fig. 3) and the pin 348 is so positio'ned upon\ the punch distributor driving bar 228 that 352 will be held out of engagement with the associated contacts 354 and 355 at all times except when the punch distributor driving bar is in a position where the brushes carried by the'punch distributor driving bar are in engagement with the last three columns of contacts I2I at the right hand side (Fig. 1) of the contact plate I28. connected to'ground at 36I. The contact 354 is connected through a conductor 362 to the conductor 83 running to the electromagnet 84. The contact 352 is connected to grounded battery at 363 -and the contact spring 355 is connected through a conductor 364 to the conductor I58.

A card supporting table 318 (Fig. 1) adapted to receive'a (card to be perforated is supported between the side plates 238 and 239, and after information has been stored in the relays I23, the card may be positioned upon the table 318 where it will, upon operation of the punch key, have its right hand edge engaged by a card feed lever 3" (Figs. 5 and '7) pivoted upon a bracket 312 at 313, and normally urged downwardly, being of resilient material. The .bracket 312 travels with the punch distributing bar 228 to which it is (Fig. 10) through a conductor 338,

228 will be moved to the tact plate I28, only The contact 35I (Fig. 10) is secured, and moves the card .i'eed lever 3" across the card supporting table 318 wherein there is provided a groove 314 (Figs. 1 and 7) in which the card feed lever 31I travels and into which the card feed lever tends to move upon passing over the right hand edge of the card (Fig. 1). When the card is positioned upon the card supporting table 318 and the punch distributordrlw ing bar moves to the right (Fig. 1) the card feed lever 31I will meet the left end of the card and slide over it until the card feed lever reaches its extreme right position where it will drop off the card into the groove and as the punch distributor driving bar is driven to the left will advance the card under the punches 235 in a step-by-step motion. The card supporting table is provided will be perforated as it moves step-by-step thereunder.

In the event that it is desired to perforate constant information in predetermined columns of a plurality of record cards, there has been provided a group of gang punching keys 388 (Fig. 1) for controlling such an operation. There is provided one gang punch key 388 for each column of perforations on the record card, and these keys which may be of any known type that will lock in either their' actuated or unactuated positions are provided with two pairs of electrical contacts 38I and 382, and 383 and 384 (Fig. 10). 4

Since all of the keys 388 are of exactly the same construction and are connected in a similar manner to their respective contacts I 2| on the con- I one key will be described. The contact 38I is connected through a conductor 385 to its associated contact I2I in the top row of contacts; the contact 382 is connected through a conductor 386 to contact 383 is connected through a conductor 388 to grounded battery at 389,

through a conductor 398 to a fixed normally made contact 39I associated with a relay 392.

There is provided one relay 392 for each group of relays I23. The relays 392 are of a construction similar to that of the relays I23 in that they are mounted upon the common plates I21 and additional projections I28 that their armatures 394 do not serve as contacts, but actuate contacts 393 breaking contact between the contacts 393 and the fixed contacts 39I uponenergization of their associated relays 392. The conductor 398 is also connected to the common conductor I39 so that any relay I23 which is operated in a row in which a key 388 is operated will have grounded battery connected to one side of its winding until the key 388 is moved to its inoperative position. Each of the relays 392 has its contact 393 connected to one side of its windingand the same side of the winding of'therelay is connected to grounded battery at 395, whereas the other side of the winding of the relay is connected through a conductor 396 to the contact I2I associated with the I 2I is longer the other brushes 22 I, and when the brushes associated with the upper rows of contacts are engaging the extreme left hand row v of contacts, the bottom brush will be engaging the next to the last row of contacts to the left (Fig. 1). This bottom brush is connected through a conductor 40I to a right hand back contact 402 of the relay 285 which contact is normally in engagement with a right hand movable 1 contact 403 connected to ground at I54. A movable contact 404 of the relay 235 is connected to grounded battery at I54, and normally engages a fixed contact 405 which is connected through a common conductor 405 to one side of the windings of all of the electromagnets 245, the other side of the windings of which are connected through a plurality of conductors 401 to the brushes 22I on the punch distributor carriage 203.

It is believed that a clearer understanding of the invention will be had from a detailed description of the mode of operation of the various elements heretofore described. To facilitate the description of the operation of the mechanism an explanation thereof will be given in connection with the perforating of a record card into which it is desired to perforate certain information and it will be assumed that it is desired to perforate in the first to the twelfth column of the record card the perforations representing the numerals I2, II, 0, I, 2, 3, 4, 5, 3, 9, 8, 1 respectively, to leave unperforated the thirteenth to twenty-fifth columns of the record card and to set the numbers 3, 4, 8 and 9 in the twenty-sixth, twenty-seventh, twenty-eighth and twenty-ninth columns respectively, not only of the first card to be perforated but of a group of succeeding cards, and that it is desired to leave the thirtieth to forty-fifth rows, inclusive, of the card unperforated. In order to accomplish this the machine should be brought to normal as shown in Fig. 1 and then keys I3, 43, 44, 45, 45, 41, 48, 49, 50, 53, 52, and should be operated in succession and in the order named and thereupon the space key 55 should be operated thirteen times. After the space key 55 has been operated thirteen times, the keys 41, 48, 52, and 53 should be operated and the keys 330 associated with the twenty-sixth, twenty-seventh, twenty-eighth and twenty-ninth columns should be operated at any time prior to the operation of the punch key 54, and the space key 55 should then be operated sixteen times in succession.

When the key I3 is operated it will complete a circuit from ground at 03 through the conductor 35, contact 30, contact 29, conductor 33 to the winding of the electromagnet 34, which will be energized due to thefact that the other side of its winding is connected through the conductors I50 and I5I, contacts I52 and I53 to grounded battery at I54. Ground will also be connected from contact 21 to conductor 51 and brush '53 to contact I2I in the second row from the top (Figs.

1 and 10) of the contact ,plate I20 and thence through conductor I35 to the winding of relay I23 associated with the digit I2 to energize the relay since the other side of its winding is connected through conductors I39 and 390, and contacts 39I and 393 to grounded battery at 395. Thus the relay I23 associated with the digit I2 will attract its armature to complete a holding circuit from grounded battery at 395, contacts 333 and 39I, conductor 390, common conductor I33 through the windings of the relay to its armature, and thence through the projections I28 to the plate I21 which is connected to ground at I33. The relay I23 associated with the number pleted for each of the keys I3 and 43m 53 as 5 they are actuated in the order named hereinbefore; that is, as hereinbefore described the relay associated with the number I2 will be locked up for he first row of contacts I2l at the right hand side of the contact plate I20 10 simultaneously with the energization of the electromagnet 84. Theelectromagnet 84 which is slower to act than the relays I23 upon being energized over the hereinbefore described circuit will attract its armature I55, causing the pawl I03 to be drawn out of engagement with the notch I31 with'which it is associated, and will permit the spring I58 to move the relay distributor driving bar I22 to the left (Fig. 2) one notch since the pawl I19 will also be moved up- (Figs. 1 and 2) will bring the brushes mounted upon the bar into engagement with the second 25 row of contacts I2I on the contact plate I20. When the key 43 is operated, similar circuits will be completed to lockup the relay I23 associated with the number II in the second row of con-, tacts I2I on the plate I20. As the keys 44, 45, 46, 41, 43, 49, 50, 53,52 and 5| are operated in the order named the relay distributor carriage I02 will be stepped across the contact plate I20 from right to left (Fig. 1) to bring the brushes mounted thereon successively into association with the columns of contacts I2I, and will lock up the relays representing the numbers carried by the keys I3 and 43 to 53 in the order in which the keys were enumerated hereinbefore.

Since it is desired to leave the card imperforate in the 13th to 25th inclusive rows of possible card holes, the space key will be operated thirteen times and upon its operation will complete the following circuit: from ground at 86 over conductor 35 through the contacts of the key 55, conductor 33 to the windings of the magnet 54, which will be energized thirteen successive times and will move the relay distributor carriage I02 and associated brushes over the contacts I2I in the 13th maybe moved to their actuated positions where they will complete circuits from ground at 331 60 through the contacts 382 and "I, conductors 335 to the contacts I2I on the contact plate I20 associated with the 26th, 27th, 28th and 29th rows, and circuits will be completed from grounded battery at 389 through the conductor 338, contacts 333 and 384, conductors 390 to the common conductors I39 associated with the relays I23 which are associated with the contacts in the 26th, 27th, 28th and 29th rows of contacts III on the contact plate I20, thereby to hold ener- 79 gized any relays which have previously been energized. In the problem selected for illustration, there are the relays associated with the digits 3,

-4, 8 and 9, over circuits independent from those energized in a group associated with an operated ganspunch key 380 will not be deenergized during the punching operation. Similar circuits will be completed upon operation of any of the gang punch keys 380, and these keys maybe operated immediately after'the keys in the key box I2, but preferably are operated after information for an entire record card has been set up.

If in the particular group of cards which are to be perforated, the 30th to the 45th rows inelusive, are to have no perforations therein, the gang. punch keys 330 for those rows may be moved to their actuated positions, thus to cause the relay' distributor carriage I02 to skip over these rows automat'rmme operation or any gang punch kQor group of gang punch keys 330 will' complete a circuit from ground at 381 through the contacts 382 and 33I, conductor 385; contact I2I associated with that particular gang punch key 380-, brush I00, a conductor 400 interconnecting '.brush I and the contact I 8|, through thecontacts HI and I82,the windings of electromagnet 34, conductors I53, II, contacts I52 and I53 to grounded battery I54, thereby to cause the operation of the electromagnet 84 each time the brush I33 engages a contact I2I which has been grounded due to the operation of its associated gang punch key 380. This operation will be caused due to the fact that the pawl I19 in returning to normal position will move the contact -I3I into engagement with the contact I32, and

since the pawl I19 returns to the position shown in Fig. 2, after each operation of the electromagnet 84, if gang punch keys 380 associated with successive rows of contacts I2I are in their actuated position, the electromagnet 84 will be operated a number of times in succession to permit the relay distributor carriage I02 to move its brushes rapidly overthe columns of contacts I2I where the"condition just outlined exists.

From the description of operation thus far, it will be apparent that the relay I23 associated with the first row of contacts at the right of the contact plateI and representing the digit 12 has been locked up to hold ground on its associated contact. In like manner relay I 23 associated with the contact I2I' in the second row of contacts from the right of the contact plate I20, representing the digit 11 has been locked up to connect ground to its associated contact I2 I, the

relays I 23 representing the digits 0, 1, 2, 3, 4, 5, 6, 9, 8 and 7, and connected to the contacts in the 3rd to 12th rows inclusive of the contacts I2I, have also been locked up, no relay associated with the 13th to th rows of contacts on the contact plate,l20 has been locked up, the relay I23 as sociated with the digits 3, 4, 8 and 9 in the 26th,

27th, 28th and 29th rows of contacts respectively have been locked up to place around on their associ'ated contacts, and no relays I23 associated 'with the 30th to th rows of contacts I2-I havebeen energized. However, the relay distributor carriage I32 will have-been advanced over the contact plate I20 toacarry all of the brushes mounted thereon past the extreme left hand row of contacts I2I on the contact plate I23 and in moving to this position will have caused the plunger I93 to engage the abutment 201 and thereby to make contact between the contacts 233 and 234 to prevent the operation of any key in the key box I2 due to the completion of the circuit from ground through the contacts 234 v and 233 to,.the windings of the electromagnet 31,

the other side of the windings of which are connected to grounded battery. The closure of these 'tributor carriage 203 to prevent the operation of any of the keys in the key box I2 when the '5 punches are close enough together to cause a possible error in the setting up of a problem to be perforated.

If a wrong number has been set into the relays I23, the back space key 56 may be operated to 1b mechanically drive the relay distributor carriage backward through the operation of the back space pawl I85 which will first be moved into engagement with the notches I6I on the relay distributor driving bar I22, and will thereafter be moved I! to the right (Fig. 2) to step to carriage back one space. Simultaneously with this mechanical movement of the carriage to the right (Figs. 1 and 2) the back space key will complete a circuit through its contacts from ground at 86 (Fig. 10) 20 through brush 82, and the contact I2I with which the brush is associated 'to the relay 392 associated with the row in which the wrong information has been stored, thereby to momentarily actuate the relay 392, causing a break between the 20 contacts 39I and 393 which will automatically release any actuated relay I23 due to removal of grounded battery" from one side of the winding thereof by the breaking of contact between contacts 39I and 393.

A card in which it is desired to perforate the information stored in the relays I23, may now be placed upon the table 310 from which it will be picked up and advanced step-by-step under the perforating pins 235 by the card feed lever In order to start the punching operati'on','the key 54 should be operated. The operation of key 54 will connect ground from 279 through the contacts of the key, conductor 280, to the wind- 40 ing of electromagnet 23I, the other side 'of the winding of which is connected to grounded battery at 282, and ground will also be connected from the contacts of the key through the conductor 280, a branch conductor 233 to the winding 15" of relay 285, the other side of the winding of which is connected to grounded battery at I54. The energization ofthe electromagnet 23I over the circuit just described will cause it to attract its armature, thereby to remove the pawls 295 and 296 from the notches formed on the under side of the punch distributor driving bar 223, allowing the spring motor 225 to drive the punch distributor driving bar 220 and the relay distributor driving bar in to the right (Figs. 1, 2 and a) since the coil spring I83 will have moved the relay distributor bar to the left to bring the plunger I93 into engagement with the abutment 231, and the abutment will serve to drive the relay distributor driving bar to the rightwith the punch distributor driving bar. The operation of relay 235 will disconnect grounded battery at I54 from one side of the winding of the electromagnet 84 ,due to the disengagement of contacts I52 and I53 and will also break thegrounded battery coi1- engages the bottom row of contacts I2I on the contact plate I23. Furthermore, the momentary energization of the relay 235 in its, energized position due will lock the relay to the'completion of the circuit from grounded battery at I54 through the winding of the relay, contacts 214 1 ground at 331. This circuit will be "maintained through the contacts 332 and 335 until the punch distributor driving bar 220 reaches a position where the brushes on the punch distributor carriage 209 are in engagement with the extreme right hand row (Fig. 1) of contacts I2I on the contact plate I20. The energization of the relay 235 thereby prevents the operation of the electro- 10':-

magnet 34 and also prevents the release of any of the relays 123 which are locked up due to the removal of the ground connection'from the brush 22I. As the punch distributor carriage 200 reaches the end of its travel to the right (Figs. 1 and 3), the contact between contacts 332 and 335 will be broken due to the pin 32I-(Fig. 3) moving the slide bar tothe right (Fig. 3) and the pin 329 will engage the contact spring 33I, thereby to move it into engagement with the consprlng 333 (Figs. 3 and 9). When the contact 33I engages the contact 333, it will complete a circuit through the motor 355, and the disengagement of contact spring 332 from contact spring 335 will remove ground from relayv 285,

' .thereby deenergizing it as the drive motor 353 rotates to drive the shaft 25I for the 45 punching cycles required.

The punch distributor driving her 220, upon reachingthe end of its stroke to the right (Figs.

and 5) will carry the card feed lever 3" to the right beyond the right edge .of a card placed upon the card supporting table 3I0 permitting the card feed lever 3' to drop behind the edge of the card, and when the motor 355 starts to drive theshaft 26l', the card will be advanced by the card feed lever 3'. The shaft 25I upon being rotated by the motor 350 will reciprocate the pawl as through the cam m to drive the punch distributor carriage 200 'step-by-step' across the contact plate I20 (Figs. 3-and 9) and through the cam 210 will oscillate the shaft 256 to alternately store tension in the springs 255 in'opposite directions. The punch distributor driving bar 220 as it carried the brushes on the punch distributor carriage 209 onto the third column oi contacts i2I from the right of plate I20 (Fig. l) in the movement of the distributor bar to the right, caused the contact 35I to lng bar I22 which has the notches cut away at this point, so that when the punch distributor carriage 230 starts to travel to the left due to the operation of the driving pawl 296, the relay distributor carriage I02 will follow it until the *brushes carried by the relay distributor carriage are in. engagement with the first column of contacts'at the right hand side (Fig. 1) ofthe contact plate I20, at which time the pin 349 wili disengage from the lever 3.49 and the contact between contacts m and an, and m and as respectively will be broken.

' When the brushes 22I engage the first column of contacts at the right side of contact plate I20, the upper brush 22I, (Figs. 1 and 10) will be connected to ground since the relay I23 representing the digit 12 in that row has been locked up to connect ground through the conductor I35 to its associated contact and ground will therefore be transmitted through the conductor 401, associated with the I2 contact in the first column, to 5 one side of the winding of the electromagnet 245 representing the digit 12, the other side of the winding of which is connected through the conductor 406, contacts 405 and 404 to grounded battery at I54, whereupon the electromagnet 245 10 representing the digit 12 will be energized to release its interposer bar 240 and since all of the interposer bars are at that time being urged to the left (Fig. 5) by their springs 255, the bar 240 associated with the digit 12 being released by its 15 electromagnet 245 will be moved to the left, whereupon-the cam 252 will drive the actuating ram 254 downwardly to drive the perforating pin 235 which is positioned under the interposer bar 240 associated with the digit 12 through the record card. Shortly after the actuating ram 254 has been driven downwardly it is retracted to its normal positionas shown in Fig. 5 and carries with it theperforating pin 235 which was driven downwardly. In moving upwardly the actuating ram 254 will release the interposer bar 240, and since the spring 255 has had tension stored therein in the opposite direction by the cam 210, the interposer bar will be drawn back to its normal position. The electromagnet 245 associated with the retracted interposer bar'wiil b'e deenergized .due to the advancement of the brushes 22I out of engagement with the contacts I2I .in the first column of contacts at the right side (Fig. 1) of the contact plate I20 and the interposer bar; will 1 be latched in its retracted position as shown in Fig. 5. Continued rotation of the shaft 26I will advance the record card to be perforated step-bystep underthe perforating pins" 235 and will perforate it in accordance with the information stored in the relays I23. I

The lower brush (Figs. 1 and 10) mounted on the\punch distributor carriage 208, will engage the lower row of contacts in each column successively, one row back of the rest of the brushes 22I, and in so doing will operate the relay 392 (Fig. 10) associated with each row as the brush engages the contact I2I of that row due to the completion of the following circuit: From ground at I54 through contacts 403 and'402, conductor 40I to the bottom brush 22I, through the contact I2I, conductor 395 to the winding of relay 392 which is connected to grounded battery at 395. I Energization of the relay 392 will cause its armature 394 to be attracted, thereby breaking the circuit through contacts 393 and 39 I, and removing ounded battery at 395 from one side of the windings of all of the relays I 23 in that particular row. However, if a gang punch key 380 associated with one of the rows has been operated, the grounded battery at 389 will be connected through the contacts 383 and 384, conductor 390, through the-common conductor I39 so that in a row where a gang punch key 380 has been operated the operation of the relay 392 will not affect'the'relays I23 in that row since they will be connected through the contacts of the key 380 to grounded'battery until the key 380 has been moved to inoperative position. Thus the punch to be used for listing or like operations where it ceive a second problem.

After the punch key 54 has been operated, the operator may immediately start to put a new set .of information into the relays I23, while the punch distributor carriage is completing its travel across the contact plate I25, thereby expediting greatly the operation of the machine. As previously described, the keys I3 and 43 to 55 inclusive will be locked in the inoperated position by plate 33 if and whenever the relay distributor brushes approach within two columns on plate I of the punch distributor brushes.

In order to permit the perforation of alphabetical information in record cards which are is desired to control printing mechanisms to print other than numerical data, there is provided an alphabetical key board 4| I! for controlling applicants perforator in a manner such that combinations of holes may be punched in each column of a record card. This keyboard is provided with a key 4| I for each letter of the alphabet and for each of the digits 1 to 9 and the .numbers 5, II and I2 as well as keys H2, H3 and M4 for controlling spacing, punching and backspacing respectively.

The alphabetical key board 4I|I is mounted at the front edge of the base II and may be used .interchangeably with the key board heretofore described for the perforation of holes representing numbers. Thekeys 4 are similar to the keys I3, 43, 44, etc., the difference being that the keys 4 representing the letters B, C, D, E, F,

H, J, K, L, M, N, P, Q, R, T, U, V, W, X and Y are each provided with an extra contact and control the setting up of information in two relays I23 in each row associated with the keys at the time they are operated. The keys 4| I representing the letters A, G, I, O, S and Z control the same relays I23 as do the keys 43, 55, 45, 44, 52 and I3, respectively, and have their contacts connected in parallel with the contacts of the keys 43, 55, 45, 44, 52 and I3, since when cards are to be used for printing control a perforation in the position allotted to the number I I will cause an A" to be printed a hole in the I2 position will cause a Z to be printed and the same printing characters are used for the letters G, I, O, and S as are used for the digits 6, 1, 0 and 8, respectively. In like manner the keys 4| I representing the numbers I2, 0, I, 2, 3, 4, 5, 5, 1, 8 and 9 are connectedin parallel with keys I3, 43, 44, etc. representing the numbers I2, II, n, I, 2, 3, 4, 5, 5,1,8 and 9, respectively, and the contacts of the punch key 4|3, the space key 2 and the backspace key 4|4 are con- I nected in parallel with thepunch key 54, the space key 55 and the backspace key 55, respectively.

The construction of the keys 4 is such that upon operation of a key all of the contacts of the key will be interconnected and one contact of each key is connected to the conductor 55 leading to ground at 85 and another contact of each key is connected to the conductor 93. The keys 4 representing the letters B, C, D, E, F, H, J, K, L, M, N, P, Q, R, T, U, V, W, X and Y have their other two contacts connected to conductors 59 and 5|, 59 and 53, 59 and 55, 59 and 51, 59 and 59, 59 and 1|, 59 and 13, 59v and 15, 59 and 11, 59 and 19, 51 and 5|, 51 and 53, 51 and 55,51 and 51, 51 and 59, 51 and 1|, 51 and 13, 51 and 15, 51 and 11, and 51 and 19, respectively.

From the foregoing it will be apparent that the keys B, C, D etc. will cause two relays I23 to be locked up in a row of relays each time one of them is operated and that the keys 4| I representing the letters B, C, ,D, E, F, H, J, K, L, M, ,N, P, Q, R, T, U, V, W, X, Y will cause the punching of perforationsinthe II and 0, II and I, II and 2, II and 3,

and 9, Hand 0, I2 and |,'|2 and 2, I2 and 3, I2 and 4, I2 and 5, I2 and 5, I2 and 1, I2 and 8, and I2 and 9, hole positions in the, rows in which the keys are associated at the time of their operation.
