DUPLICATING PUNCH George F. Daly, Johnson City, and Gunne Lowkrantr, Endicott, N. Y., assignorl, by memo assignments, to International Business Machines Corporation, New York, N. Y.', a corporation of New York Application January 19, 1933, Serial No. 852,500

9 Claim.

This invention relates to punching machines or perforating machines and more particularly relates to machines of the type wherein the punching may be controlled either manually or by a previously punched card.

The machine of the instant invention is adapted to be used in connection with a duplicating punching machine of the type disclosed in Letters Patent of the United States No. 1,772,186, issued August 5, 1930, to F. L. Lee et al. Such a punching machine, when operated as set forth in said patent, is adapted to punch data-representing holes in a blank card under the control of a pattern card, under the control of manually operated keys or both. The purpose of punching under the control of two sources was that in punching a number of cards certain data were to be punched on all of the cards. Stated otherwise, certain data were fixed for all of the cards to be punched and certain other data were variable for each 1 card. In operating the machine disclosed in the above mentioned patent, the fixed data are first punched in a pattern card and this card placed in the machine in the proper position. The machine is then operated to punch the fixed data in the blank card after which the variable data are punched manually, or vice versa the variable data are first punched manually and then the machine automatically punches the fixed data.

The machine disclosed in the above mentioned patent is flexible in that data may be punched manually before or after punching data under the control of a pattern card, or both before and after. But greater flexibility is desired in that in certain systems large numbers of cards are punched in groups. That is to say all of the cards are to have certain fixed data punched in a given field.

Other data to be punched in another field are peculiar to each group of, for instance, 250 cards. Finally other information peculiar to each card is to be recorded. The fixed data may be punched in all of the cards under the control of a pattern or master card. The data, which varies with each card may be punched manually by suitable keys, however, a more expeditious manner of punching the data which varies with each group, than is ofiered by the pattern card or the manually set punches is desired. The provision of means to accomplish this result forms the sub- Ject matter of and the chief object of the instant invention.

Another object is to provide in a machine of the type indicated a device on which data may be semi-permanently set to control entering mechanism.

A further object of the instant invention is the provision of novel and convenient means for setting up alphabetical descriptions forthe purpose of controlling a punching machine to punch said descriptions in suitable tabulating cards.

Various other objects and advantages of our invention will become apparent from the following description of the preferred form or embodiment of the invention or from an examination of the drawings which accompany and form a part of this specification.

Fig. 7 is a top plan view of the duplicating punch. For convenience the present invention will be described with reference to a machine of the type disclosed in the patent to Lee et al. No. 1,772,186, and it is desired here to point out that it is not limited to use with such a machine but it may be used in connection with other machines with equal facility.

A pattern card I is placed upon a reading table 2 and is held between rearwardly extending arms 3 attached to a card carriage 4 (Fig. 6) so that step-by-step movement of the carriage will feed the card I toward the left (Fig. 7). During this movement of the card I the perforations in the columns of the cardare read by I! contacts I1 illustrated diagrammatically in Fig. 4, said contacts cooperating with an insulated contact roll it rotatably mounted in a housing 5. The thirteenth contact Ila engages the roll i8 to one side of the card and serves to connect the latter to the duplicator circuits.

There are as many contacts i'l as there are index points in the card columns and each contact is connected to punch selecting magnets 25 associated with punches III for the corresponding index positions.

The punches iii are supported for vertical r eciprocating movement in the machine frame and are normally urged upwardly by springs l I which press the upper ends of the punches against the lower side of horizontally reciprocable interposer go bars II. There is one interposer II for eachpunchand the left hand ends of said interposers l2 are adapted to be interposed between their associated punches and an operating bail I 3 so that, upon operation of said ball, the selected punch will be operated to perforate a blank card .6 inserted between the punches and a die bar l4.

In order to selectively thrust the interposers |2 leftwardly between the punches and the operating bail |3 a pluralityof manually operable keys I5 is provided. Bell cranks |6 couple the stems of the keys l5 with the corresponding interposers in such a manner that, upon depression of a particular key, the corresponding interposer I2 is thrust leftward for the purpose set forth above.

The keys |5 may be operated either manually or by the magnet 25 under the control of the pattern card I (Fig. 7). It will be understood that when a magnet 25 is energized it will attract its armature 23 and rock counterclockwise a lever 29 and thus effect depression of the corresponding key IS.

The selected punch is operated by magnets 3| (Figs. 3 and 4) which are normally deenergized. These magnets are adapted to be energized through the agency of the displaced interposer l2 in the following described manner:

A pivoted bar 32 (Figs. 3 and 3a) extends across beneath all of the interposers l2 and a spring 34 constantly presses the bar 22 against the right hand walls of notches 33 in the interposers. The left hand wall of a notch 35 in the lower edge of a link 36 is held in contact with the bar 32 by the inherent spring tension of a switch blade 31 carrying one of a pair of contacts 38.

When any one of the interposers I2 is shifted leftwardly to its effective position, it rocks the bar 32 counterclockwise drawing the link 36 therewith to close the contacts 38. This establishes a circuit from the source l9 (Fig. 4) through the punch magnets 3|, contacts 33 back to source thus energizing the magnets 3|.

Energization of the magnet 3| attracts and rocks their armature 39 counterclockwise. A link 40 couples the armature 39 to a bell crank 4|, the bell crank being connected to the punch operating bail l3 by a link 42, thus transmitting the movement of the armature 39 to the bail l3 which is rocked downwardly to operate the selected punch through its interposer bar I2. A pair of toggle links 41 (Fig. 3) is provided to limit the counterclockwise travel of the armature 39 to prevent said armature from striking the'cores of its magnets. Near the end of the punching stroke of the bail l3, an oppositely extending arm 43 thereof raises the left hand end of the link 36 sumciently to permit said link to escape the bar 32 whereupon the inherent tension of the switch blade 31 shifts the link toward the right to normal position, thus opening the contacts 38 and deenergiz'ing the punch magnets 3|.

A block of insulating material 44 (Fig. 3a) suitably mounted on the link 36 near the left hand end thereof, is carried upwardly with said link, serving to open the contacts 26 (Figs. 3a and 4) thus opening the circuits to the key operating or duplicating magnets 25 as soon as the selected punch has been operated.

The contacts 2|, 22 and 23 illustrated in the circuit diagram (Fig. 4) are provided for the following special purposes: The contacts 2| are adapted to open as soon as the last column on the card has been perforated thus openingthe duplicator circuit. The contacts 22 are arranged to openafter the last selected column in the card has been automatically duplicated, and the contacts 23 are provided to open the duplicator circuits when the card picker 96 is out of its fully retracted position. 5

A suitable escapement device including pawls 45 (Fig. 3) and 46 suitably mounted in the machine is adapted to be operated under the control of the punching mechanism. This escapement device is preferably of the type disclosed in the patent to J. T. Schaafl 0. 1,426,223, issued Aug. 15, 1922, and is ada ed to permit a step-by-step advancement of the pattern card past the sensing means H in synchronism with the passage of the blank card, that is, the card 15 being punched, past the punches III.

This escapement mechanism is operated by the selected interposer |2 when operated by the punch operating bail l3. When the bail l3 is operated as set forth above, the left hand end of the selected interposer I2 is moved downwardly therewith to operate the punch. The downward movement of the interposer rocks a bail (Fig. 3) counterclockwise to raise the escapement dog 45 (see also Fig. 6) and to lower the locking dog 48 into engagement with an escapement rack 9| secured-to the pattern card carriage.

The relative movements of the escapement dog 45 and the locking dog 46 are such that the locking dog 46 engages a tooth in the rack 9| 30 before the dog 45 is fully disengaged therefrom. The dog 45 is pivotally mounted on an extended end of the shaft 92 supporting the bail 90 and has a slot (not shown) the end of which abuts said shaft 92. The dog 45 is also provided with 35 an opening 93 into which projects a pin 94 carried by a short arm secured to the shaft 92, said am being normally urged in a counterclockwise direction by a spring tensioned between a fixed part of the frame and a tail formed on 4 the dog.

When the shaft 92 is rocked by the bail 90, the arm fixed on said shaft, which arm carries thepin 94, is rocked clockwise (Fig. 6) to raise the dog 45 and disengage the nose of said dog 45 clear of the tooth of the rack, the spring 95 draws the dog 45 toward the left (Fig. 6) so that the nose of said dog overlies the space interjacent the teeth to the left (Fig. 5) of the space in which the nose of dog 45 formerly rested.

50 When the punch magnets 3| are deenergized,

' in the manner described above, the bail 90 rocks clockwise to its normal position (Fig. 3) and the dog 46 is raised to release the carriage rack 9|, whereupon the carriage and its rack move 55 one step or space toward the left (Fig. 3) or toward the right (Fig. 6). Since, at this time, the dog 45 overlies the space between the next two teeth to the left (Fig. 6) this dog, upon advancement of the rack 9|, rides into said space 60 to prevent the carriage from escaping more than a single tooth space, which space corresponds to the inter-columnar distance on the record card and pattern cards.

Thus it can be seen thateach time the conan invariable extent manually by means of a handle 99 (Fig. 7) to bring the first column on the left of said card beneath the punches III. At the same time by means of a gear I66, shaft IOI and gear I62 as is fully disclosed in the above mentioned patent, the pattern card carriage 4 is shifted toward the right to bring the corresponding column on the pattern card beneath the contacts II. The pattern card I and the blank card 6 are then fed in unison step-by-step past the contacts l1 and the punches respectively.

As the blank card 6 is carried leftwardly by the picker 96, it passes beneath a finger I 63 carried by an arm I64 secured on the pattern card carriage. This finger drops down behind the card 6 and, as the carriage 4 is advanced step-by-step, carries the card 6 therewith.

It is not thought necessary to burden the specification with a full detail description of the machine in connection with which our invention is adapted to be used. For a complete understanding thereof reference may be had to the above mentioned patent to F. L. Lee et al., #l,772,186, and to the patent to J. T. 'Schaaif #1,426,223.

The above briefly described punching device effects punching of invariable data on all of the cards under the control of the pattern card and effects punching of data which varies with each individual card under the control of the manually operated keys.

By using our improved punch control device in connection with a duplicating punch machine of the above mentioned type data set on said device may be punched in each card of a group after which the set-up may be changed and other data punched on the cards of a succeeding group in conjunction with the invariable data punched in the cards of the first group under the control of the pattern card, and in addition the data which varies for each individual card may be punched under the control of the keys.

The device on which data may be set manually, but temporarily, to control the selection of punches for a plurality of columns to punch the data set on said device in the corresponding columns of a plurality of cards comprising a group, includes a main frame i (Figs. 1 and 2). Mounted to slide horizontally in the frame 5i is a plurality of slides 52, each slide being supported by a pair of plates 53 from which project studs 54. These studs fit within longitudinal grooves in the sides of the slides 52 to guide said slides in their reciprocatory movement. The plates 53 are tied together by rods 55, the lower corners of the plates being supported in projections of the frame 5|. The ends of the rods 55 are secured in end plates 56 (only one being shown herein) which are held against upward displacement by the heads of screws 51 in bosses 56 projecting from the frame 5|, which bosses also serve to support the end plates 56.

Spring aliners 59, secured to the underside of cover 60 cooperate with aiining notches H in the upper edges of the slides 52 to retain said slides in their set positions. Index plates 62 are secured on top of the slides 52 and are adapted to be read through a sight opening including a plate 63 of glass or other suitable transparent material, upon which glass are engraved or otherwise suitably marked index lines to enable the operator properly to set the slides.

A contact arm 64, having two fingers 65 and 66, is mounted on a block of insulating material 61 cured to the main frame by any convenient 5 means. As the finger 66 successively comes into contact with the contacts 66, the finger 66 is in constant contact with a conductor II (see also Fig. 4) All of the contacts 66 of like digital value,

for instance, allof the 9" contacts are connected together, all of the 8 contacts are similarly connected, etc. These contacts 68 are also connected by wires I2, which wires may be convenientiy gathered into a cable, to the corresponding wires 24 thus connecting the contacts 68 to the corresponding duplicator magnets 25.

Each of the conductors II (Fig. 4) is connected by a wire I3 to a corresponding columnar contact 14 spaced along a dielectric bar I5 (see also Fig. 3) secured to the casing I6 of the punch mechanism. It is to be understood that there is provided for each column on the card to be punched, a slide 52 and a corresponding'contact I4.

Obviously any one or all of the slides may be set to control punching in their corresponding columns. Those slides 52 which it is not desired to use may be shifted to their extreme left hand position (Fig. 2) carrying the fingers 65 out of contact with the extreme left hand contacts 66 (as shown in Fig. 2) thus opening the duplicator magnet circuits for those particular columns.

Extending upwardly from the left hand end of the pattern card carriage 4 is a bar I6 (Fig. 3) carrying near its upper end a two pronged wiper blade I9. The lower prong 66 of this blade is 85 adapted successively to engage the columnar contacts I4 as the carriage TI is fed leftward stepby-step. The upper prong 6i of the blade I6 wipes along a conductor 62 extending the length of all of the contacts I4. The conductor 62 is connected by a wire 63 (Fig. 4) and the wire 26 to one side of source I9. This completes a circuit from the source I9, wire 63, conductor 62, wiper contact I9 to the selected columnar contact I4, thence by the wire I3 to the conductor strip II, 5 fingers 65 and 66 to the selected contact 68, wires I2 and 24 to the particular magnet 25, contacts 26 and back to source through wire 21.

As soon as the wiper contacts I9 move onto a contact I4 whose corresponding slide 52 is set, the circuit just described is completed and the selected magnet 25 is energized to operate the corre-- sponding key I5 thus, as above set forth, shifting the interposer I2 toward the left (Fig. 3).

Near the end of its leftward movement, the interposer I2, acting through the universal bar 32 and the link 36, closes the contacts 38, energizing the punch magnets 3| to operate the bar I3 thus punching a hole in the column corresponding to the particular slide 52, and in the index position corresponding to the setting of said slide.

The downward movement of the interposers I2 under the influence of the bar I3 effects an escapement to permit thecarriage to move to the next column, carrying the contacts I9 therewith into (35 contact with the next succeeding columnar contact I4. This closes the circuit for this column and energizes the magnet 25 in accordance with the setting of the slide 52 for this column.

It will be noted, by reference to Figs. 1 and 5, 70 that the letters in the index positions on the slides 52 and on the card are not arranged in any regular order or sequence. For instance, in the first alphabetical column on the left the twelfth, eleventh and zero positions respectively are represented by the letters "3, "0 and D whereas the corresponding positions in the next column to" the right are represented by the letters A, B and C. The reason for arrangingthe letters of the alphabet in this fashion is that these letters, when read of! from the card on which they are punched, are adapted to control a printing mechanism to print the names or alphabetical descriptions of the various articles handled by, for

, the example illustrated in Figure 1, the fifth and sixth slides from the left are set to bring the numerals 5 and 4 respectively to the index positions. The seventh slide is set to a blank position while the eighth and ninth slides are set respectively to and LB. The tenth, eleventh and twelfth slides are set to blank positions. The thirteenth to twentieth slides inclusive are set to spell the word cleanser.

After this data is set on the slides 52 the punching machine is operated in the usual manner whereupon, in addition to the data punched under the control of the pattern card I (Fig. '7) and the keys I5 (Fig. 3), the data set on the slides 52 are punched in the proper columns.

Referring now to Figure 5, which represents a facsimile card punched with the above described data, it can be seen that holes are punched in the proper columns to represent the data set on the slides 52. These data represent 54 LB cleanser and will be punched on all cards so long as the setting of the slides 52 is not disturbed. In the columns to the left of and also to the right of these data additional numerical data may-be punched either under the control of a pattern card or by the keys i5.

Therefore, in addition to permitting the setting up of suflicient letters to spell complete words our invention provides for the control of a punching machine to punch alphabetical values on control cards, which, when passed through a tabulating machine preferably of the type disclosed in the patent to Carroll No. 1,726,539, issued September 3, 1929, or in application for Letters Patent Serial No. 579,136 filed Dec. 5, 1931, by G. F. Daly et al-., controls such tabulating machine to print the words or names in the proper columnar position on the record material.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, 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.
