15 Claims.

This invention relates to record controlled machines and more particularly to machines controlled by perforated'record cards of the Hollerith type. y

The principal obj'ectof the invention resides in the provision of anJimproved form of record card having increased data receiving capacity.

A more specic object of the inventionis to provide improved means for interpreting data representingperorations in my improved record card, said means being in the form of an attachment which can readily be utilized in connection with commercial -tabulating, printing, sorting, and like accounting machines.

A still further object of the invention is to provide means fo'r sensing and interpreting a column of a record card in which code perforations representing two characters are punched and in which the perforations may occupy any index point ,0 position orA positions in the column.

A still. further object is to provide means for sensing both entries in a column of a card during a single transit of the column by a sensing station and controlling two separate printing devices, each in accordance with a diiferent one of the two entries.

In carrying out the objects of the invention, one or all of the columns of a Hollerith record card may' be doubly punched, once to represent a letter of the alphabet or a digit, and a second time to represent another digit.

,The well known Hollerith card usually has alphabetic characters represented thereon by a ,two-hole code punching, one being made in the *0, 11, or 12 index point positions known as 3 5' the zone positions and the second in one of the digit index point positions 1 to 9.` Thus, the letter A is represented by holes in the 12 and 1 positions. If now it is desired to enter a'digit, say, 3 in the same column, a hole is punched in the 3 index point position.

For the purpose of reading this doubly punched column it is necessary to distinguish which digit hole is the companion of the 0, 11 or 12 zone hole. This is effected by providing a key hole made in the margin of the card in line with the perforated column when the digit hole alone is greater than the digit hole belonging to the letter. When thel condition is reversed, no key hole is required. A third condition, namely, that in which both digit holes are the same, as where an A and a 1 are punched in the same colunm or two Bs etc., requires a differently located key hole to identify such condition and control the machine accordingly. 55 Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of .o the accompanying drawings; and the invention also constitutes certain new and useful features of construction and combination of parts hereinafter set forth and claimed.

The invention will be described to show how it may be attached to a printing machine, but it 5 lwill be apparent that it may with equal facility be attached to other forms of accounting and statistical machines.

Fig. 10 is a section through the card feeding .30 mechanism of an accounting machine showing the special brushes for sensing the card of Fig. 9.

Fig. 11 is an enlarged detail of one of the brush sensing stations of Fig. 10.

The printing mechanism will rst be described 35 to explain the manner in which it is controlled and operated when only a single character isy entered in a card column after which it will be set forth how, with the use of the attachment constituting the invention, two characters punched in a single column may be concurrently sensed to concurrently control two separate type bars. y

The printing mechanism may be of any suitable form, but for convenience may be assumed to be substantially identical with the one del scribed in Patent No. 2,016,682, granted to A. W. Mills, October 8, 1935. It includes the usual platen I0 (Fig. 4)- and a number of vertically movable type bar assemblies including carriers 50 I2, slidably mounted on each of which are type heads I3. The purpose of this type of construction will be explained more fully hereinafter. Each type head has type elements I4 adapted to print the numerals 1 to 9 andthe letters A to Z. 55 The type elements Il are arranged in nlnegroups in the following order from top to bottom in Fig.

4: 9, I, R, Z; 8, H. Q, Y; '7, G, P, X; 6, F, O, W; 5, E, N, V; 4,'D, M, U; 3, C, L, T; 2, B, K, S; 1, A, J. Below the type elements I4 are two zero 50 type elements I4a, I4b referred to hereinafter as the numeral zero and the alphabetic zero, respectively, Which are separated from each other by a distance equal to that between centers of three successive type elements I4. 'I'he numerical type elements I4 correspond to the usual numerical type elements of a conventional Hollerith type bar, but are spaced far enough apart to make roomf for three alphabetic type elements between successive numeral type elements.

The numeral type elements are selected for a printing operation in identically the same manner as kin conventional Hollerith tabulating machines, for instance, as in Patent No. 1,822,594 under control of a perforation in one of the index point positions 1 to 9 of a record card column. The alphabetic type elements are selected under control of combinations of perforations, each of which may comprise a perforation in one of the index point positions 0, 11, and 12, with another in the remaining nine indexpoint positions; thus, the letter I of the type group is selected by the combination of a 9 perforation and a 12 perforation in one of the columns of the record card; the letter R by a 9 perforation and an 11 perforation. The entire 4code is similarly arranged and the particular combinations are as set forth in the Patent No. 2,053,243, granted Sept. 1, 1936, to A. W. Mills, Serial No. 701,444, i'lled December 8, 1933. l

The selection of the alphabetic type elements I,4 is effected by arresting each carrier I2 in the appropriate position corresponding to the value of a perforation in `index point positions 1 to 9 of the record card and by further movement of the type head I3 relative to its carrier one, two, or three steps according to whether the other perforation of the combination necessary for a selection is in the 12, 11 or 0 positions, respectively.

As a matter of convenience, the four positions of the type elements. in each group are termed zones 1, 2, 3, and- 4, the numeral type being in zone 1, the letters A to I being in zone 2, the letters J to R in zone 3, and the letters S to Z in zone 4. The 0, 1l, and 12 perforations which control the selection of the alphabetic type elements are termed zone perforations. The mechanism which effects relative movement between each carrier I2 and its type head I3 may be termed the zoning mechanism.

Each carrier I2 is provided with a series of stops I5 which represent the corresponding index point positions 0 to 9' on the record card. LAs the carrier I2 is moved upwardly, the stops I5 move in succession to pass a stopping pawl I6. The latter is held in the position of Fig. 4 by a latch I'I which has connection I8 with armature I9 of the usual printing magnet 20.

When a type carrier is used to print numerals only, it will, of course, be controlled by a single perforation in one of the index point positions 0 to 9, inclusive. In such case, each type head I3 and its carrier I2 is maintained in the relationship shown in Fig. 4, and as the card is passing the lower analyzing brushes, a circuit completed through the perforation in the card will energize the magnet 20 in a well known manner and will effect the release of pawl I6, causing it to engage the stop I5 corresponding in value to the location of the single perforation in the record card column. This operation results in bringing the corresponding numeral type element in the type head I3 to the printing line.

The carriers I2 are moved upwardly by a cam operated shaft 2I which carries arms 22 having oted at 25. Also pivoted at -25 are actuating arms 26 which are connected at their free ends to the lower extremity of carriers I2 through link connections 21. Arms 26 'are urged in a clockwise direction by springs 28 which are connected at their upper ends to a cross bar secured to arms 22. Thus, as the arms 22 and bail 24 are rocked in a clockwise direction by shaft 2|, the springs 28 will rock the arms 26 in the same direction and will cause elevation of the carriers I2.

The manner in which the type bar assemblies comprising carriers I2 and heads I3 are constructed to permit relative movement will now be explained, after which the zoning mechanism whereby such relative movement is effected will be set forth briefly.

The carrier I2 is shown in Fig. 4 as being provided with a slot 29 and al guide 30 which are adapted to receive a slotted block 3l and the lower end 32 respectively of the type head I3, the block sliding within the slot 29 and the lower end 32 sliding in the guide 30. A spring 33 whose lower end is anchored to the carrier I2 is provided at its upper end with a hooked member which engages the lower edge of an opening in the shank of the type head I3, the spring 33 tending to resiliently hold the head I3 in cooperation with the carrier I2.

Mounted upon the lower portion of each carrier I2 is a slide 36 provided with grooved blocks 31 which cooperate with suitable slots in the` carrier I2.. A spring 39 anchored at its lower end to the carrier I2 and at its upper end to the slide 36 tends to move the slide downwardly to bring a shoulder 40 in the slide into engagement with a block 4I rivetedto the carrier I2. With the parts assembled as in Fig. 4, the spring 39 draws the slide 36 downwardly and spring 33 urges the type head I3 in the same direction so Ilat the lower end 32 thereof engages the slide It is plain that if the slide 36 is moved upwardly relative to carrier I2, the head I3 will move likewise.

A spring-pressed latch 42 pivoted at the lower .end of the carrier I2 is adapted to cooperate with three shoulder stops 43 formed in the slide 36. When the slide is moved upwardly one or more steps with respect to the carrier, the latch 42 will cooperate with one of the steps 43 to hold the parts in their displaced relationship. 'Ihe manner in which such displacement is automatically effected under control oi the zone perforations in the card will now be explained.

Associated with each alphabetic type bar assembly is a vertically slidable comb 44 which is vadapted to be moved downwardly andthen upwardly during each cycle of the machine. Each comb has a series of three stops or lugs 45 which on the upward movement of the comb passes a stopping pawl 46 in synchronism with the passage of the zone perforations 0, 11 and 12 by the upper analyzing brushes of the machine. Each pawl 46 is controlled by a zone magnet 41, the energization of which operates its armature to release pawl 46, allowing the latter to be moved by its spring into engagement with one of the stops 45. By this action, further upward movement of the comb 44 is prevented for the time being. The combs '44 are moved upwardly by means of a spring. and moved downwardly by a bail 52 secured to a shaft 63. The bail engages the upper ends of the combs and moves the lat ter downwardly whenever the shaft'53 is rocked at the proper time by a suitable cam (not shown). v

'I'he comb 44 has pivoted thereto an arm 55 whose free end lies in the path of movement of the associated slider 36, and whose lower kedge rests upon a bail 56 which isfpivoted at 51. Under control of the zone perforations the pivot point of arm 55 may take one .of three positions below that of Fig. 4. In this figure the parts are shown with the comb in the position it assumes when no zone holes are present in the card; that is,

when numerals only are to be printed. When the carrier I2 is in its lowermost position, the bail 56 is rocked in a counterclockwise direction to move the arm 55 in a similar direction into engagement with the lower extremity of slide 36. It will be apparent that the distance which the free end of arm 55 is moved upwardly under control of the bail 56 depends upon the location of the pivot point of arm 55 at such time. Thus, if the pivot point is located as shown in Fig. 4, the free end of arm 55 will be moved upwardly to a position where it barely touches slide 36. A zone perforation in the index point position will result in the movement of the free end of arm 55 three steps upwardly from the position of Fig. 4. A perforation in the 11 position will cause it to move two st'eps, while .a perforation in the 12 position will cause it to move only one step above the position in Fig. 4. These steps of movement are, of course, transmitted to the slide 36 and it, in turn, will be moved upwardly one, two, or three steps in accordance with the setting of the related comb 44, the latch 42 carried by the carrier I2 serving to hold theslide at its displaced position with respect to the carrier.

Bail 56 ,is actuated through the medium of a toggle mechanism comprising links 5 8, one of which is pivoted to the bail and the other is pivoted to an arm 6 I. The point of connection of the links 58 carries an arm 62 which is also pivoted to an arm 64 secured -upon a cross shaft 65. `The shaft 65 is rocked in a counterclockwise direction once each card cycle by a suitable cam (not shown) thus tendingto straighten the toggle comprising links 58.

An arm 66 carried by a rod 61 is adapted to be the straightening of the toggle links 58. When shaft 65 is rocked in a counterclockwise direction under control of its cam, the right end of arm 6I will be engaged by arm 66 so that the pivot point of the toggle will be restrained against downward movement and subsequently straightening of the toggle will cause the bail 56 to rock in a counterclockwise direction.

It will be understood from the foregoing description and the more detailed explanation found in Patent No. 2,016,682 that' in the case where a perforation occurs in one of the 1 to 9 index point positions only, the mechanism controlled by the zone magnets 41 will not be effective to shift slide 3 6 relative to carrier I2 and the type assembly will be arrested differentially, purely by the operation of print magnet 20, as in former Hollerith tabulating machines. On the other hand, if a zone perforation also appears in the 0, 11 or 12 positions, the magnet 41 will be effective in conjunction with magnet 20 to con- Referring now to Fig. 3. the circurs involved when a column contains only a single character will now be described. A plug connection 10 is made between sockets 1I and 12 and a second connection 13 is made between sockets 14 and 15 corresponding to the same card column.

Thereafter, as the card is advanced to pass the rows of sensing brushes LB and UB, a z one selecting circuit will be completed as the 0, 11 and 12` index point positions pass the first set of brushes. This circuit is traceable as follows: from left side of line 16, common contact roller 11, 0, 11 or l2 hole in the card, brush UB, wire 18, socket 1I, connection 10, socket 12, zone selecting magnet 41, cam contacts G (closed While position 0, 11 or 12 are sensed) to right side of line 19. Later as the digit positions pass the brushes LB, a second circuit will be completed as follows: from right side of line 19, cam contacts H, wire 80, common contact roller 8|, hole in the 1 to 9 positions, Wire 82, socket 14, connection 13, socket 15, magnet 20, wire 83 to left side of line 16.

These are the usual circuits completed to select an alphabetic character as described above and in the patent referred to. If the v'column contained only a digit perforation, then, of course, no zone selecting circuit would be completed and the magnet alone would bel energized'to select the appropriate digit type for printing.

Before describing the mechanism of the invention proper, a detailed explanation will be given of the improved record card to point out the essential characteristics thereof. An example of such a card is shown in Fig. 1 and for purposes of clearness the holes shown in three different manners. The holes having no sectioning or shading relate only to the characters printed on the upper line designated 84. The holes having section lines therein relate only to the digits printed on the lower line designated 85, while the holes that are blackened relate to both upper and lower lines 84 and 85.

upper line may first be perforated in the usual manner in any or all of the eighty columns provided. If now additional numerical information is to be .entered on the card any or all of the veighty columns are punched again with the desired digit holes just as though the columns had not already received punchings. This gives rise to three distinct conditions of which the mechanism of the invention must take cognizance. The second punching may be greater than, equal to, or less in 'value than the digit hole alreadyv made. If the second hole is greater in value, a key hole 86 is made in line with that column above the leading edge of the card. If the second hole is equal in value, a key hole 81 is made in line with the column intermediate the row of lower key holes 86 and the row of 9 holes. If the second hole is less in value, no key hole is required.

It will be understood, of course, that the punching of key holes is effected only Where two separate items are punched in a column and that where only a single item is recorded, whether is corresponds to printing on line 84 or 85, no key holes are necessary. t

The several different conditions are shown in the enlarged diagram of Fig. 2. In this figure a 3 is punched in the first column and as this item stands alone, no key punching accompanies it. The second column containsthe letter A coded as a 12 and a l hole and the numeral 3. Since the 3 hole is greater in value than the 1 of letter A, the key hole 86 is made at the extremity of the column. The third column contains the letter A and a 1. Since the "1 holes coincide, key hole 81 is made. Again, in the fourth column, the numerals in both lines 84, 85 are 6 and key hole 81 is also made. Finally, in the last column a G coded as a 12 and a 7 hole and the numeral 3 are entered. Here, since the 7 is of greater value than the 3 no key hole -is required.

'I'he interspersed perforations made in accordance with the above described arrangement are to be concurrently read to cause printing on a single line as represented in Fig. 5 with the data shown in line 84 printed in any position of the sheet and the data shown in line 85 printed in any other position, either adjacent to one another or with the characters interspersed according to the manner in which connections are made as will `be described.

Referring now to Fig. 3, there is provided'for each column from which double punching is to be read a relay and commutator unit comprising a stepping relay 88, pairs of contacts 88a and 88h, a relay 89, with its contacts 89a and 89h and commutators B, C, D, and F, timed to electrically connect their related brushes as shown in Fig. 6. Each uniti-fis wired to plug sockets 90, 9|, and 92 as shown.

Considering now a single double punched card column, a plug connection 93 is made from the socket 14 of the brush LB that traverses this column and a second plug connection 94 is made from socket 92 to the socket 15 whose magnet 20 controls print selection in the position .of the record sheet wherein the character on line 84 is to be printed. A plug connection is also made between the corresponding plug sockets 1| and 12 As a preliminary it must be assumed that, as

will be later explained, contacts 88h are normally closed and contacts 88a open, and the operation will be more clearly understood by tracing through specific examples, one for each different condition.

Let it therefore be iirst assumed that the column to be sensed contains perforations 'corresponding to a G.on line 84 and a 3-on line 85 as in Fig. 2. As the 0, 11 and 12 positions pass brushes UB, the zoning magnet 41 is energized through the circuit traced above in the position in which G is to be printed. As the card passes the lower brushes and when the "7 hole is sensed, a circuit is completed as follows: from line 19, contacts H, wire 88, common contact roller 8|, 7 hole, brush LB, socket 14, connection 93, socket 90, stepping relay 88, contacts 98h, brushes of commutator C 4(now electrically bridged, see Fig. 6), socket 92, connection 94, socket 15, magnet 20, wire 83 to line 16. Energization of magnet 28 at the 7 time in conjunction with the zone selection by the 12 hole will position the selected type bar to print the letter G.

Energization of relay 88 will rock its armature 96 and raise pawl 91 to engage the next tooth of ratchet 98 which has connected to it an alternating cam 99. As the 7 hole passes brush LB the circuit just traced is broken and pawl 91 descends under the influence of its spring and advances ratchet 98 to turn cam 99 a tenth of a revolution so that one of its high points lies able as follows: from line 19, contacts H, wire 80, common contact roller 8|, 3 hole, brush LB, socket 14, connection 93, socket 90, relay 88, contacts 88a, brushes of commutator B, socket 9|,

connection 95, socket 15, magnet 28 selected to,

print from line 85, wire 83 to line 16.

Relay 88 by its inclusion in the print selecting circuit thus normally causes the first hole sensed by the lower brushes to print in the position selected to receive the item relating to line 84 and upon completion of the first circuit to effect switching so that the second circuit will con`` trol printing in the position selected to print the item relating to line 85. Incidentally, the second energization of relay 88 will cause further stepping of ca m 99 vto again close contacts 88h and open contacts 88a.

Let us consider now a second example wherein the hole relating to line 85 is greater and key hole 86 is present. Since the zoning operation under control of brushes UB is the same for all conditions, it need not be described again and the operation as regards the sensing by the lower brushes LB only will be set forth. At the moment the hole 86 is at the lower brushes, commutator F connects its brushes and permits completion of a circuit from line 19, contacts H, wire 80, common contact roller 8|, key hole 86, brush LB, socket 14, connection 93, socket 90, relay 88, contacts 89h, brushes of commutator F to line 16. Relay 88 thereupon causes shifting of contacts 88a, 88h so that now when the 3 hole arrives at the brush LB the first printing circuit will be completed through contacts 88a to energize magnet 20, related to line 85 and the lcontacts will thereafter be again shifted so the second printing circuit through'the 1 hole will be through now closed contacts 88h and the magnet 20 related to line 84 will, in cooperation with its zoning magnet, select the letter "A for printing.

For this condition, therefore, magnet 88 will have been energized three times so that contactsv 88b are open and must be returned to normal closed position before the next card is sensed. For this purpose, contacts A are provided which close at the time indicated in Fig. 6 completing a circuit from line 16, contacts A, contacts 88a (now closed), relay 88, socket 98, connection 93, socket 14, brush LB, contact roller 8| (there being no card between the brushes and roller at this time), wire 88, contacts H to line 19. Energization of relay 88 will thereupon restore its contacts 88h to normal closed position. It may be observed that closure of contacts H at this time will complete circuits to all magnets 28 connected to single item card columns through connections 13. The time of such circuit completion is, however, before the magnet armatures are mechanically restored so that this energization has no effect. A

'I'here yremains now the third condition wherein both items are represented by the same digit hole, for example, A and 1 in Fig. 2. As

this column .has its key hole 81 presented to brush LB, commutator D bridges its brushes and a circuit is completedvfrom line 19, contacts H, wire 80, roller 8|, key hole 81, brush LB, socket 14, connection 99. socket 99, relay, contacts 75 88h, brushes of commutator D, relay 89, wire |00, to line 18. Relay 89 closes its contacts 89a and 89h, the former setting up a holding circuit for the relay traceable from line 16, wire |00, relay 89, contacts 89a, contacts E to line 19. Also as a consequence relay 88 will cause closure of contacts 88a. Thereafter when the 1 hole arrives at brush LB the print selecting circuit will follow from brush LB to socket 14, connection 93, relay 88, contacts 88a, brushes of commutator B, socket 9|, connection 95 to socket 15 and magnet 20 related to line 85. The circuit will also follow a branch from the brushes of commutator B, through contacts 89h, socket 92, connection 94 to socket 15 and magnet 20 related to line 84. In

.the switch |0| is effected when cards without interspersed punching are run through the ma.

chine and eliminates the consequent idle operation of the magnets 20.

Modification A modified form of record card in which two items are recorded in a single column with interspersed perforations is shown in Fig. 9 and sensin g means therefor in Fig. 10.

In this case, the perforations related to the upper line of printing 84 are made in the normal manner. Those relating to the line 85 instead of being made in the same index point positions are punched in the positions intermediate the normal positions. In Fig. 9, the holes relating to line 85 are sectioned to better distinguish them and where in the mainform of Fig. 1 two holes coincided, they now form a single hole of double length and no key holes are required.

The only change in present machines required to sense the card of Fig. 9 is to substitute for the single line of brushes LB a double line -LB and LBa as shown in Figs. 10 and 11 each with a separate common bar |02 and 4|03 respectively. The brushes as spaced a distance apart equal to half the distance between two successive index point positions so that when brushes LB are on the 9 position related to line 84, brushes LBa will be on the intermediate 9 position related to line 85.

Plug connections |04 are then made as in Fig. 7 from sockets 14 connected to brushes LB to sockets 15 of magnets 20 that are to control printing in accordance with line 84 and connections |05 are made from sockets 14 connected to brushes LBa to sockets 15 of magnets 20 that are to control printing in accordance with line 85. Contacts K are timed as in Fig. 8 to make as each pair of like item representing holes are at their respective brushes and break between sensing positions.

If a similar double brush UB and UBa is provided, the zoningl perforations may also be doubled to permit alphabetic data to be represented on both lines 84 and 85 and the brushes connected in the same way as for the lower brushes LB and LBa.

Tracing of an example will make the simplicity of the arrangement clear. Let us consider the column of the card containing the letter A and numeral 1. When the l hole of the letter A is at brush LB, the l hole of the numeral will be at brush LBa and closure of contacts K at this time will complete a circuit from line 19 (Fig. '7), contacts K, wire |06, common |02, brush LB, socket 14, connection 04, socket 15, to magnet 20 of line 84, and wire |01 to line 16. Concurrently a circuit runs from line |06, common |03,'brush LBa, socket 14, connection |05, socket 15 and magnet 20 of line 85 and wire |01 to linejS.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to two modifications, it vwill be understood that various omissions and substitutions and changes in the forms and details of the devices illustrated and in their operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention therefore to be limited only as indicated by the scope of the following claims.
