9 Claims.

This invention relates to record controlled machines and particularly to duplicating machines like those used to reproduce wholly or in part record cards used in accounting and statistical machines like the Hollerith machine, for example.

The broad object of the present invention is to improve the construction and operation of machines referred to above, commonly known as electric duplicating key punches, wherein a suitable master card bearing data-designating control perforations is used to control the operation of a record perforating machine in accordance with the perforations appearing inthe master card, whereby certain columns or fields of the master card are duplicated in a similar card. Such machines are well known in the art and are illustrated in Patent No. 1,772,186 granted to Lee and Phillips.

It is usual to duplicate in a blank record card certain portions of the master card, skip other portions or fields in both cards, and insert in the blank card manually such additional information or data as may be desired, suppressing in the meantime control by the master card. It is common practice when it is desired to skip fields in the master card to punch an X hole as it is called in the eleventh index point position of the first column of each field which it is desired to skip and the machine is provided with mechanism which, through the control of said X hole, causes the reading devices to skip the desired columns and moves the blank card accordingly so that no perforations will be made in the portions of the blank card corresponding to the columns to be skipped in the master card.

Cards which have been punched with an X hole may subsequently be again punched with further data which may have to be inserted in the fields in which an X hole may appear, consequently it may be impossible to use said cards as master cards to duplicate the new portions of the master cards owing to the fact that the skip bar which was previously used with that particular master card has been cut with the necessary notches to control the stopping of the carriage in the desired columns. Since the X hole always appears in the column on the left of the group to be skipped and is the first perforation read by the reading devices, the X hole will become effective before any of the following data designations will be read by the reading device, consequently the machine would skip the entire field regardless of the presence of other data appearing in the field which it is desired to duplicate.

As it would be expensive to be repeatedly changing the skip bars on the machine to suit changes in the master card which may become necessary as time goes on, mechanism will be provided according to the present invention to cause the machine to disregard the X hole when it occurs in conjunction with another data designating hole in any column so that the machine, instead of skipping the field in which the hole appears, will duplicate such data as if the X hole were not present.

It is one of the broad objects of this invention to provide mechanism for causing the machine to disregard certain perforations appearing in any column of a card used as a master card, which perforations would ordinarily control the machine in a given way, said mechanism being so arranged as to cause the machine to be controlled in a way different from the ordinary way.

Various other objects, advantages, or features of the present invention will be more fully pointed out'in the following specification and claims or will be apparent after a study thereof and of the accompanying drawings.

In said drawings:

For the purpose of illustration this invention will be described as embodied in a machine similar to that shown in Letters Patent No. 1,772,186 to Lee and Phillips. Since the general details of construction of such a perforating mechanism are now well known in the art and fully shown in said patent they will be only briefly described herein.

There is provided the usual card carriage comprising a rack 10 and arms 11 extending transversely on each side of the rack between which arms a master card 12 and blank card 13 are adapted to be received and fed side by side in spaced relationship from left to right (Figs. 1 and 4) under the influence of a suitable carriage feeding spring and escapement mechanism. For this purpose the card carriage 10 is mounted in suitable guides extending transversely of the machine and is provided with anti-friction rollers 14 which permit the card carriage to move freely from left to right and vice versa.

Before punching operations are commenced a feed lever 15 (Fig. 6) on the right hand side of the machine is grasped and fed toward the left (Fig. 1) thereby feeding a blank card 13 from the magazine at the right end of the machine (Fig.1) towards the left in said figure into position to be gripped by suitable holding devices on the arms 11, during which preliminary feeding movement of the card the carriage 10 will be drawn 'to the right (Figs. 1 and 4). When the feed lever 15 has thus been operated, a series of punches 16 will be in position to perforate in the first column of the blank card while a series of reading brushes 17 will be in position to read perforations which may occur in the first column of the master card 12.

The brushes 17 are mounted on an insulating block 18 carried by a bail 19 which ball is pivoted on plates 20 loosely mounted on a cross rod 21 extending between frame plates 22. Links 23, pivoted to a fixed part of the frame and to the ends of the bail 19, serve to hold said bail erect.

Pivoted to the plates 20 are parallel integrally joined links 24 which in turn are pivoted to an armature 25. The latter is pivoted at 26 to suitable studs in the machine frame and is normally held against a fixed stop 27 by means of a spring 28 interposed between the end of said armature and the cross shaft 21. Cooperating with the armature 25 is a magnet 29.

Mounted above the brushes 17 is an insulated contact roll 30 journalled in a housing 31 pivotally mounted at 32 to the frame of the machine. Fixed to the housing 31 is a bar 33 which overlies the master card 12 throughout its length when the carriage is in its extreme lifthand position as in Fig. 4, and prevents said card from buckling. The left end of the bar 33 is held down by a spring-urged latch 34 and said bar 33 is normally spring-urged upwardlyso that when the latch 34 is released the spring will rock the bar 33 and housing 31 about 32 as a pivot thereby raising the contact roll 30. Fixed to the left end of the bar 33 is a stud 35 carrying an insulating button which holds a pair of contacts 36 closed as long as the bar 33 is latched down.

There are thirteen brushes 17 of which twelve cooperate with the usual twelve index point positions in the columns of the master card 12 while the thirteenth brush serves as a common brush to connect the contact roll 30 to the circuits of the punching mechanism. Associated with each brush 17 is a contact finger 3'1 carried by an insulating block 38 fixed to the frame. Each finger 3'7 normally presses against the side of the shank of the corresponding brush 1'7.

The contacts 36 are in series with the magnet 29 across the line 39 (Fig. 8) through contacts 40 (normally closed) which are opened when feed lever 15 is operated and also through contacts 41 (also normally closed) which are opened whenever a similar feed lever 42 at the left end of the machine is operated. The lever 42 is provided for the purpose of feeding the carriage 10 to the right (Figs. 1 and 4) whenever it is not desired to feed a blank card 13 from the magazine.

When the master card is to be placed in the machine, it is merely necessary to unlatch the bar 33 while the carriage is in its extreme leftward position as in Fig. 4 and slip the master card between the arms 11 of the carriage 10 and then press down the bar 33 until it is latched thereby closing contacts 36 and energizing magnet 29. Energization of the magnet 29 causes the latter to attract its armature 25 thereby drawing the links 24 to the left (Fig. 4), rocking plates 20 about shaft 21 in a counterclockwise direction and raising the ball 19.

Owing to the links 23 the ends of the brushes 17 will rise in substantially a straight line until said brushes press the underside of the master card 12 beneath the contact roll 30 against said contact roll. Each brush 1'! is guided in a separate slot 43 in an insulating plate 44 mounted 1m in a suitable opening in the frame beneath the contact roll 30 which slots prevent the brushes from touching or otherwise interfering with one another. The raising of the brushes 17 does not break the connection between the shanks of the 1m brushes and the contact fingers 3.7 which are arranged to bear on and hence make good contact with said shanks in both the raised and lowered positions of the brushes.

Associated with armature 25 is a pair of contacts 45 which are closed whenever the-armature is attracted to the poles of magnet 29. The purpose of the contacts 45 will be more fully explained hereinafter.

The punches 16 are arranged to be controlled either by a series of manually operable keys 46 or by the perforations appearing in the various columns of the master card through brushes 17 and magnets 47 each of which is associated with a key 46 and is adapted to operate said key through the medium of a pivoted lever 48. Said levers 48 are rockably mounted at 49 in the frame of the machine and have a pivotal connection at 50 to the stem of the associated key 46 so that the key may be depressed either manually or through energization of the appropriate magnet 47. There are twelve keys 46 corresponding to the twelve index point positions in the columns of the record card and associated with each key is a punch 16 which is designed to make a perforation in the index point position corresponding either to the appropriate key 46 or a brush 1?.

Depression of any key 46 rocks counterclockwise (Fig. 1) a bell crank 51 pivotally mounted in the frame and carrying a pin projecting through a slot in a punch interposer 52 which is moved to the left (Fig. 1) whenever the key is depressed. The left end of each interposer 52 normally overlies one of the punches 16 and is provided with a notch 53 normally underlying a rib carried by a pivoted plate 54. When the selected interposer is'moved to the left as just described, the notch 53 is moved out of cooperative relation with the rib in the plate 54 so that the solid portion of the interposer comes between said rib and the head of the punch. At the same time the interposer moves to the left, a pivoted plate 55 is rocked counterclockwise (Figs. 1 r and 5) thereby raising a hook 56 which thereupon closes a pair of contacts 57 in series with a punch operating magnet 58 thereby connecting said magnet across the line 39.

Energization of magnet 58 causes the latter to attract its armature 59 and through a system of links and a bell crank will draw down plate 54 thereby forcing the selected punch through the blank card 13.

The foregoing operation of punch magnet will cause the left end of the selected interposer 52 to be drawn downwardly thereby rocking a bail 60 in a counterclockwise direction (Fig. 1). The bail\60 is fixed to a rock shaft which extends rearwardly over the rack 10 and carries integral therewith arms which raise a dog 61 and lower a second dog 62. Normally the dog 61 engages suitable escapement teeth in the upper edge of the rack 10 while the dog 62 is normally out of engagement with said teeth. Rocking of the bail 60 in the foregoing fashion first causes the dog 62 to be moved into engagement with the teeth in rack 10 before the dog 61 clears said teeth. As soon as the dog 61 clears the teeth in rack 10 a spring 63 draws said dog 61 (Fig. 2) to the left so that the end of said dog overlies the next adjacent tooth space to the left (Fig. 2) in readiness to slip into said tooth space when the dog 62 is withdrawn from engagement with the rack 10 on the return of the bail 60 to normal position.

When the magnet 58 attracts its armature a projection 64 mounted on one of the links operated by said armature moves the hook 56 out of engagement with spring contact members 57 causing said members to break the circuit therethrough and deenergize the magnet 58 thereby permitting release of the armature 59 and restoration of bail 60 and the selected interposer 52. This operation will result in raising the dog 62 to its normal position (Fig. 2) thereby permitting the carriage to escape one tooth space to the left (Figs. 1 and 4) or to the right (Fig. 2).

When the dog 61 is raised by the rocking of bail 60 during a punchnig operation a member 65 loosely mounted on the shaft supporting'the dog 61 and ball 60 is raised by said dog and a pin 66 on said member 65 operates to break contacts 67 and close contacts 68 which are fixed in the machine frame, the contacts 67, 68 being timed so that contacts 68 close before contacts 67 break. The contacts 68 are held closed until the selected interposer has been restored to its normal position and the carriage has escaped a full column space by mechanism best illustrated in Figs. 2 and 3.

Fixed to the shaft upon which is rigidly mouned plate 55 is a T-shaped member 69 adjacent to which is loosely mounted a member 70 spring-urged clockwise (Fig. 3) relative to the T-shaped member 69. Normally the position of the parts is that shown in Fig. 2 wherein a lug formed in member 70 lies to the left (Figs. 2 and 3) of a lug 71 in the member 65. The member 70 has a bent-over portion 72 which when the parts are in normal position as in Fig. 2 abuts against one of the transverse lugs in member 69 against which it is held by a spring. When an interposer 52 is moved to the left by depression of a key 46 or energization of one of the magnets 47, the plate 55 will be rocked counterclockwise (Fig. 1) or clockwise as in Fig. 3, as described hereinbefore, thereby causing the T- shaped member 69 to rock clockwise (Fig. 3).

Since the lug in member 70 is in the path of the lug 71, the spring interposed between members .69, 70 will be merely tensioned by the rocking of member 69. When the punch magnet 58 is energized through closure of contacts 57 the dog 61 will be raised as described thereby closing con tacts 68 and at the same time moving the lug 71 out of the path of the lug in member 70 which will then through the force of its spring be forced under the lug 71 and prevent the member 65 from being restored until the plate 55 has been completely rocked back to its normal position.

Thus the contacts 68 are held closed until the interposer has reached its home position by which time the carriage will have fully escaped one column space and the machine will be in readiness for punching in the next column of the blank card. The common member of the contacts 67, 68 is connected to one side of the line 39 through the contacts 41 already mentioned. The contacts 67 are connected to the thirteenth or common brush 17 which establishes the circuit to the contact roll 30, the brushes 17 being each connected to one of the magnets 47. The contacts 68 are connected in series with the contacts 45 a skip operating magnet 73, hereinafter to be described more fully in detail, to the contacts of a relay 74 and relay contacts 75 to the right side of line 39.

Machines of the type illustrated are usually equipped with a suitable skip bar 76 (Figs. 2 and 6), the function of which is to cause the machine to automatically skip fields in which it is not desired to perforate. In order to cause the machine to skip a field, it is necessary to lift the dog 61 independently and without causing dog 62 to engage the rack 10. The skip bar 76 is removably mounted at one end on the carriage 10 and 'is designed, through suitable notches 77 cut.

therein, to control the skipping of columns, the notches 77 being provided for the purpose of arresting the carriage when the desired number of columns have been skipped. As the operation of this skip bar mechanism is fully described in the patent referred to hereinbefore, only a brief description will be given of its operation describing only the parts which are new and modify the operation described in the patent.

It is customary in perforating record cards to make a perforation in the eleventh index point position of the first card column of the field which is to be skipped, such field comprising a plurality of columns in the card. When a card that is so punched is used as a master card 12 to control the punching mechanism in duplicating operation, the reading devices will sense the presence of such perforation in the eleventh index point position, or X hole as it is called, and will control the machine to skip the entire field and bring the carriage to rest in the first column in which punching is to be resumed.

Each of the brushes 17 is connected to the magnet 47 which controls the punch for the index point position of the master card 12 which the brush is positioned to read and all of the magnets 47, except the one associated with the is connected through relay magnet '74 and contacts '75 to the right side of line 39.

a The relay magnet '79 is part of a quick acting relay and operates to close contacts '75, the magnet 79 operating fast enough to close said contacts before any of the magnets 4'7 can operate the interposers 52.

In order to lift the dog 61 without lowering the dog 62 there is provided a member 81 (see Fig. '7) which is slidably mounted in a stud 82 and is drawn by a spring 83 toward the front of the machine, that is, toward the right in Fig. 7.

The rear end of the member 81 or the left end as shown in Figs. 6 and 7, overlies the upper edge of the skip bar 76 and is loosely guided in a narrow opening in a part of the frame which permits the left end (Fig. 6) of member 81 to be raised yet prevents lateral movement axially of the skip bar '76. The left end of the member 81 where it overlies the skip bar '76 is narrowed so as to form a cam surface 84 in said member which narrowed end underlies the dog 61 (Figs. 2, 3, and '7) Normally the narrowed portion 85 occupies the position shown in Figs. 2, 3 and 6 in which position the narrowed portion adjacent cam surface 84 just clears the top edge of the skip bar '76. When the member 81 is moved to the left (Fig. 6) and held by means hereinafter described, the cam edge 84 causes said member to be cammed upwardly thereby raising the dog 61 and releasing the carriage whereupon the usual carriage feeding spring will draw the carriage to the left until one of the notches '77 (Figs. 1 and 2) comes under the edge of the member 81 which then will be released and will drop downwardly thereby permitting the dog 61 to engage one of the teeth in the rack 10 and arrest the carriage. The consequence will be that the carriage will first be released owing to the presence of a single X hole in the master card 12 and then will be arrested when the desired number of columns have been skipped as a consequence of the presence of the notch '77 which has been cut in the skip bar to correspond with the column in which punching is to be resumed.

It will be understood that the member 81 will be held in the position shown in Fig. 9 during the time the carriage is moving to skip the desired columns. The means for shifting the member 81 and holding it in shifted position during the time the carriage is moving to skip the desired columns comprises a vertically extending lever 86 pivotally mounted at 87 to a bracket 88 supported by one of the frame plates of the machine, the lower end of said member 86 extending into a notch formed in the member 81. The member 86 is secured to a bail 89 between the arms of which is secured an armature cooperating with the magnet '73 hereinbefore mentioned, the armature being secured to the inside of the bail 89 by suitable screws 90.

It'will be seen that energization of magnet '73 will cause the member 86 to be rocked clockwise (Fig. 6) and held thereby moving the member 81 to the left against the tension of spring 83 and will result in raising the dog 61 in the manner described previously.

The operation of the machine will now be described in detail with reference principally to Fig. 8. The master card to be duplicated in whole or in part is placed in the machine in the fashion hereinbefore described, by first releasing the latch 34 to permit the bar 33 and housing 30 to rise and then the card is slipped between the arms 11 of the carriage 10. The feed lever 15 is grasped and moved to the left as described before, causing the carriage to move to the right (Figs. 1 and 4) which operation will cause a blank card 13 to be fed from the magazine into position to be grasped by the gripping devices on the arms of the card carriage when the card carriage reaches its extreme rightward limit of travel and comes to position in readiness for punching operations.

It will be assumed that the first group of, say twenty columns of the master card, is to be automatically duplicated in the machine, and that the next ten columns are to be skipped, consenuently the first column of said latter group will have an X" perforated therein. It will further be assumed that previous accounting operations using the same card as the master card required the skipping of the remaining colunms so an X hole will appear in the thirty-first column to cause the machine to skip the remaining columns of the card but subsequent operations call for utilizing the remainder of the card for further data which is to be duplicated on a second card. Accordingly, the column which contains an X" hole of this latter group of columns will also contain another perforation which is part of the new data added tothe master card and is to be duplicated in the card along with the other perforations representing the new data in said columns but the X" perforation is not to be duplicated. The skip bar, of course, will have been designed for use with the former card and, with the machine like that described in the patent mentioned herein, the presence of the X hole in the first column of the last group of columns would ordinarily cause the machine to skip the entire group ofcolumns remaining in the card. The manner in which the normal effectiveness of the X" hole in the card is destroyed will now be described in detail.

As soon as the feed lever 15 is released after feeding a blank card and moving the carriage to the right as described the brushes 1'7 will encounter a perforation in the first column of the machine and, through a circuit established through said brushes through one of the magnets 4'7 will operate the appropriate key 46 to cause punching of the desired hole in the first column of the card and thereafter the carriage will automatically escape to the next column in which the process will be repeated and so on until the twenty-first column is reached. The machine is now to skip the next ten columns including the twenty-first.

When the carriage comes to rest after escaping from the twentieth to the twenty-first column, the brush 1'7 corresponding to the eleventh index point position will read the X" hole in the eleventh index point position of the'twenty-flrst column and a circuit will be established as follows: Left side of line 39, contacts 41 (closed),.

column in the manner hereinbefore described;

As soon as a circuit is established through relay magnet '74, the contacts of said relay will close and establish a circuit from right side of line through contacts and magnet 74, magnet 73, and contacts 45 and 68 (closed by dog 61 when punch magnet operates), to the left side of the line 39 thereby energizing the magnet 73 and causing the member 81 to be moved to the left (Fig. 6) as described.

Eventually the carriage 10 will move far enough to the left (Figs. 1 and 4) to bring the notch 77 corresponding to the thirty-first columns of both master card 12 and blank card 13 beneath the member 81 thereby permitting the latter to drop into said notch and release dog 61. The latter then will arrest the carriage at the thirty-first column and at the same time contacts 68 will be opened as described breaking the circuit through magnet 73 and permitting restoration of member 81 to the normal position shown in Figs. 2 and 6.

The member 81 will not raise the dog 61 since it will already have been raised by the operation of the punch magnet 58 in punching the X hole in the twenty-first column but will be cammed upwardly as described hereinbefore into position to prevent the dog from reengaging the rack teeth when the punch magnet becomes deenergized. Since contacts 68 have been closed by dog 61, the magnet 73 will remain energized thereby holding the member 81 in shifted position as long as the portion of said member to the right of the cam surface 84 (Fig. 6) rests on the upper edge of the rack as in Fig. 9.

The brushes will now read both an X hole and another hole in the thirty-first column, we will say, the 0 hole. A circuit will then be established from right side of line 39, relay magnet 79, opening contacts 75, the O magnet 47, brush 17 associated with the O magnet, contact roll 30, common brush 17, contacts 67 closed, to left side of line 39 through the contacts 41 now closed. A circuit will also be established momentarily from right side of line 39, through contacts 75, relay magnet 74, switch 80, magnet 47 associated with the eleventh index point position, brush 17 reading the X hole in the thirtyfirst column, contact roll 30, common brush 17 and contacts 67 to left side of line through contacts 41. These two circuits will be substantially simultaneously established but, before the relay magnet 74 can fully close its contacts, the magnet 79 will open contacts 75 thereby preventing the magnet 74 from completely closing its contacts so that the circuit through magnet 47 corresponding to the eleventh index point position will not be established long enough to cause its associated interposer to move forward a distance suificient to cause an X hole to be punched in a blank card as said circuit will be broken immediately after it has been established so that the circuit through the O magnet 47 will alone be effective to control the O punch.

As a consequence, a perforation will be made only in the 0 index point position of the thirtyfirst column and thereafter the carriage will escape to the thirty-second column wherein a further perforation present in said column and others in the remaining columns will cause the carriage to automatically duplicate the thirtysecond and following columns. Of course, the raising of the dog 61 in escaping from the thirtyfirst to the thirty-second column will cause the contacts 68 to close, however, the magnet 73 will not become energized owing to the fact that the circuit through magnet 74 was only momentarily established.

It will be seen that when a hole occurs in the same column with an X hole, only the first named hole will be duplicated in the blank card and the machine will not skip the following columns.

When it is desired to operate the machine without using the column skipping mechanism, the

common contact of switch 80 may be connected to the lower contacts (Fig. 8) thereby preventing operation of the skip control magnet 73 under any circumstances. With switch 80 in the foregoing position a hole appearing in the eleventh index point position of any column of master card 12 will cause a similar hole to be punched in the same column blank card 13 after which the carriage will escape a single column space.
