vReferring to Figs. 1, 2 and 4a, the cards i are stacked in a magazine 2 and are fed one at a time from the bottom of the stack toward the left, into position between the perforation sensing brushes 3 and cooperating contact plates or strips 4,' 4a. 15

f/l. In this position, if there is a perforation through the card in a position corresponding to one of the brushes, that brush will reach through 20 the perforation and engage the strip 4- on the opposite side and thus close an electric circuit for Y controlling the operation of the machine.

As shown in Fig. 3, there are twelve brushes in a row so that when a particular column on` the 25 card is in registration with the column of brushes, eachbrush will engage one of the index positions on the card. A single 'such column of. brushes may be employed in the machine and the cards fed column by column to the brushes 30 to be analyzed, or as shown in Figs. 4 and 4a, several columns of brushes may be employed. In the present instance', five columns are shown.

lHere, the columns of brushes may be arranged in 'sixteen step by step analyzing operations the 45 entire card will be analyzed. With this arrangement, the printing of the data represented will be simultaneously effected in ve different positions. f f l Feeding mechanism The feeding of the cards from the magazine 2 4is eiected by a card picker or pusher 5. on an arm E xed to a rack 1 (see Figs. 4 and 4a). This rack meshes with the gear 8 loosely carried on a 55 shaft s. Fixed on this' shaft is a ratchet when III. Also fixed on shaft 9 is a worm wheel II meshing with a worm I2 xed on shaft I3 of a motor I4. Fixed to the gear 8 isa. disk I5 carrying a pawl I8 having a tooth I1 adapted to cooperate with the ratchet I0. The pawl I8 is pivoted at I8 on the disk I5 and is adapted to be actuated by a spring I 9 into cooperation with the ratchet A pin 20 fixed to the pawl I8, rests on the upper edge of one arm 2| of a toggle member which holds the pawlfy normally out of mesh with ratchet I Il. Arm 2| is connected by a link 22 to the second arm 23 of the toggle. Arm 2| is pivoted at I8 with the pawl I6, while arm 23 is pivoted at 24 to the disk I5. A spring 25 cooperates with the free end of the arm 23 and is adapted to hold it in its upper position as shown in Fig. 4a when moved to this position, and also to hold it in its lower position when moved downwardly. An arm 26 reaches over a pin 21 fixed in arm 2|. The arm 26 is fixed to rod 28 which is adapted to be rocked clockwise in Figs. 4a and 5 by the armature 29 of an electromagnet 3U. When the' magnet isenergized, it will cause the arm 26 to be depressed and this will move the toggle arms 2| and 23 downwardly where theyy will then be held by the spring 25. This, in turn, will permit the pawl I6 to move into engagement with the ratchet l0. The turning of the ratchet I0 will now cause the gear 8 to turn counterclockwise to move the rack 1 toward the left. This will carry the card I from the stack in Fig. 4a to the dotted line position la, with the first column ofperforations in register with the first column, 3a, of sensing brushes.

'I'he other columns of sensing brushes 3b," 3c,\ etc. will register with the 17th, 33rd, etc. columns of the card. From this dotted line position 1a, the card will be fed one column at a time toward the left as the 'analyzing and printing takes place. 'Ihat is, if the card is in the position Ia, .the brushes 3a will sense the perforations in the first column and effect printing under control thereof, the brushes I3b will analyze the perforations lin column |1 and also control printing, etc. As soon as these operation have been completed, the card will move one column to the left so that the row of brushes 3a will re'gister with column 2 to sense the perforation or per- 4 toward the right where it will grip the left end.v

of the card in the position la.

As the gripper reaches the position with its jaws open over the card, an arm 48 will engage a projection 41 to cause the jaws to close upon the card. At this time, the pawl I6 and toggle arm 2|, turning counterclockwise about shaft 9, will engage a stop member 48 and will be turned about their axis |8 (see Figs. 2 and 4a). This will lift the pawl tooth I1 out of ratchet 21 and at the same time positively stop the turning of gear 8. Gear 8 which is now free, will be returned in a clockwise direction by a spring drum 49 in which energy was stored during the counterclockwise rotation of the gear.

will then cause gear 8 to turn in a clockwise# 'I'his spring drum A when the rack 1 reaches its home position, lug

44 (Fig. 6) will engage the pin 45 on arm 4| and will cause the pawl 38 to be moved out of the i path of the clutch member 40 so that the shaft forations in that column and to control printing, while the row of brushes 3b will register tions and control printing; the rows of

brushes

3c, 3d and 3e operating in their columns in like manner. l

'I'he feeding of the card step by step is effected by a card gripper 3| comprising upper and lower jaws 3|a, 3|b. 'I'he card gripper is carried by a rack bar 32 provided with rack teeth 3 3 meshing with a gear 34 iixed on shaft 35, on which is loosely mounted a gear 36 meshingy with the up.- per teeth 1b of rack 1. Fixed to shaft 35 is a member 31 (Fig. 6) carrying a clutch pawl 38 actuated by spring 39 Afor` cooperation with a clutch tooth 40 xed to the gear 35. A cam arm 4| pivotally attached at 42 to a fixed part of the machine, cooperates with a roller 43 on the clutch pawl 38 and holds the latter out of cooperative position with respect to the clutch tooth 48 when rack 1 is in extreme right hand position as in Fig. 4a. As the rack 1 begins to move to the left with a card, it will cause the gear 36 to rotate clockwise and will also move the abutment stop 44 out of cooperation with a stud 45 carried by the member 4|.` This will permit the member 4I t0 35 may now turn in a counterclockwise direction.

Meshing with the rack bar 32 is a gear 5| (Fig. 4a) associated with a spring drum 52 and a governor 52a; the latter serving to control the speed of the rack when released `to jump long distances. i

When the grippers 3| grip the card in the position Ia. the parts will be held in this position against the tendency of spring drum 52 to return them toward lthe left, by an escapement device 53. The operation ofthe rocking member 54 mounted on the rod 55 fixed to armature 56 of the electromagnet 51, will 'operate the escapement device to permit the rack 32 with the card grippers 3|,.to move one step or one card column to the left. This will move the card one column with respect to the analyzing brushes 3a, 3b, etc.,

card feeding devices may be brought about by the closing of electric contacts 9| (Fig. 5) which will be held in closed position by the latch 92. Just as the gear 8 is reaching the end of its counterclockwise rotation, an adjustable Vstop member 93 carried by the gear, will engage a projection y94 on the latch 92 and will release the contacts 9| so that they may open to break the circuit through the operating motor I4.

The printing device In Fig. 7, a card is shown with several columns of perforations. As this card is fed column by column through the machine as described, the brushes 3a, etc., upon sensing the perforations, will cause theprinting of the characters represented by the perforations, at the head of each column as shown at 58. The mechanism for printing these characters is shown in Fig. 3 and comprises type elements 59 mounted in a rotating type carrier 60 xedly mounted on a shaft 6I. The type elements are held by springs 62 in normal retracted position and are adapted to be actuated by a hammer 63 to impel them against an inking ribbon 64 to print through an opening 65 ou the contact strip 4a. This will cause printing in the particular column on the card "directly under the contact strip 4a.

As shown in Figs. 4 and 4a, where several rows of brushes 3a, 3b, etc., are employed, there will be as many type wheels or carriers 60 as there are rows of sensing brushes.

The type Wheels 60 are constantly rotated and the type elements are struck by the hammer 63 the moment that the desired type element is passing the printing position. The operation is so rapid that the printing may be eected without stopping the type elements. The type hammers are pivoted at 66 and held in their upper position by springs 61. Parallel motion arms 68 are connected to an actuating latch member 69 having a tooth adapted to-cooperate with the ratchet wheel 1| which is also constantly turning in a clockwise direction. ets 1| which are fixed on shaft 12 is effected by a motor 13 having a worm 14 meshing with a worm wheel 15 on shaft 16. This shaft is pro- 'vided with a bevel gear 11 meshing with a bevel gear 18 on shaft 12. Also xed on shaft 12 (Fig. l) is a gear 19 meshing with a gear 80 which in turn meshes with a gear 8| xed on the shaft 6| which carries the type wheels 60. The

latching member 69 (Fig. 3) is normally held' out of cooperation with the ratchet 1| by spring 61. Adjacent to the latch 69 is a bell crank member 82 having a spring 83 tending to rock the bell crank 82 against the latch 69 to cause the latter to move into cooperation with the ratchet 1 I. A latch 84 normally holds thebell crank 62 from actuating latching member 69. 'Ihe armature 85 of an electromagnet 86 when attracted, rocks about pivot 81 and through link 88, lifts the latch 84 to release the bell crank 82. The bell crank will then be actuated by its spring to mlove the latch 69 into cooperation with ratchet 1 I a A projection 89 on latch 84 mayalso impart a slight movement to the bell crank 82 to positively move the latter into cooperation with the actuating ratchet. The ratchet 1| will then lift the latch 69, rocking the parallel arms 68 to lmpel the hammer 63 against the type element 59. The upper end of tne latch 69 is adapted to cooperate with a camming surface to be moved out of cooperation with-the ratchet 1|. 'I'his will move the ben crank s2 back to its norma position with respect to latch 84 which by now has been released by the magnet 86 and it will be restoredv to latching position by spring 83. The pressure of the bell crank 82 against the projection 89, undery the influence of the cam 90, will positively insure latching of the bell crank 82, and will also insure a positive knock on of armature 85.

As we have stated, if but one row of sensing brushes'3 is employed in the machine, it will take as many step by step operations to analyze the' The operation of the ratchscribed.

iiuence upon the escapement mechanism 53. But as the bar moves to the" left with the rack 32, if a raised portion 98 engages the arm 96, it will lift the latter and this, in turn, will lift the escapement pawls out of cooperation with the rack 32 and permit the latter to move to the left until the arm 96 drops into another notch or depressed portion of the bar 95.

In the disclosure of Figs. 4 and 4a, where several rows of sensing brushes 3a, 3b, etc. are employed, it will be recognized that after the carriage has moved say |6 steps to the left, the entire card will have been analyzed, and printing eected. In other words, the carriage will have moved only |6 steps to the left to effect the complete analyzing operation. The carriage may then be released at this point and permitted to escape the rest of the distance to the left. For this purpose, the bai 95 corresponding to the travel of the carriage over the 16 columns on the card, at which time the arm 96 will be raised at 9.8 by the bar 95 torelease the carriage. When the card carriage reaches the end of its travel to the left, the arm,`

This key, when depressed, rocks-a lever |02 and lifts the holding pawl 53a of the escapement without causing the stepping pawl to take hold, so that the carriage moves freely under the power of spring 52 and controlled by governor 52a.

Wiring diagram. l

Referring to Figs. 4 and 4a, it will be seen that when `there are cards in the supply magazine, these cards will depress a lever |0|a to close contacts |02a. Also when the rack 1 is in its normal position to the right, it will close contactsl03, and when the rack bar 32 and card grippers 3| may have a notch 91' |00.- The grippers will remain open until are in their normal position to the left, they will close contacts |04. This is the position of the parts before, the machine is started.

Referring to Fig. ll. closure of the switch |01 will cause the motor 13 to operate and this will cause the type wheels 60 to rotate continuously. By reason of the closed condition of contacts |04, the electromagnet |08 willv be energized and will close the lower contacts I 09 and also contacts I0. The closed condition of contacts |03 in like man.- ner causes energization of electromagnet I|| to close contacts ||2 and contacts H3. Now if the operator depresses the start key I I4 to close contacts I|5 this will complete the following circuit: from the left side of the line H6, through wire ||1, electromagnet H8, wire II9, contacts H5, contacts |09, contacts ||2, wire |20, back to the other side of the line 2|.

Thelenergization of magnet H8 closes contacts |22 to shunt-the circuit away from contacts ||5, around through contacts |22, stop keyv contacts |23, contacts |02a, now closed, to the line |2|. Magnet I|8 also closes contacts |24 to close a circuit through electromagnet 30, contacts CCB which are closed by a cam at this time (see Fig.'

12) contacts |25 now closed,`wire |25, contacts |24, to line |2|. We have seen that the armature 29 of this magnet 30 operates arm 26 to throw in the clutch pawl I1. The armature also actuates a second arm 26a. The clockwise rotation of arm 26a will close contacts 9| which will e be locked in this position by the latch 92. Closing of contacts 9| now causes the motor i4 to operate. This will cause the shaft 9 to turn and through the clutch members l1, 21, will cause the feeding of the card from the supply magazine into operating position with respect to the analyzing brushes 3. We are assuming that there is only one row of analyzing

brushes

3, 1. e., the row 3a and that the

brushes

3b, 3c, 3d and 3e are omitted or not in operation. We are also assuming that there is only one printing wheel 60, i. e. the one farthest to the left in Fig. 4 and associated with the column or row of brushes 3a.

The movement of the rack to the left will open contacts 03 and, when ,it reaches its extreme position to the left, will close contacts |06. Closure of contacts |06 will cause energization of electromagnet |21 to open contacts |25 and close contacts |28 and |29. Magnet 30 is now deenerjust been fed in and these parts remain in thisI position, held by the escapement pawl 53a.

The machine will now proceed to analyze the first column, which is under the brushes 3a, and to control printing by the type elements 59 carried by the corresponding type wheel 60. The type wheel is shown as having 36 type elements 59. Corresponding to these 36 type elements are 36 contact segments |30 on a distributing commutato r |3|. As shown in Fig. 13, 'the segments 30 aredivided into several groups corresponding to the index positions in a column on the record card.

It may be stated here, that if a.A perforation appears in one of the indexpositions ranging from to 9 and no other perforation appears in thatl column, the perforation will represent the particular numeral. If, in addition to a perforation in one of the numeral positions, there isan additional perforation in the X or R or O position, the combination of these perforations will represent one of the characters of the alphabet.

The type elements on the wheel 60 are divided into four groups. The commutator |3| turns synchronously with the operation of the type wheel 60 so that as each'type element 59 is passing through the printing .position over the ribbon 64, a corresponding one of the segments |30 will be passing overV the brush |32. When the particular type element 59 corresponding to the character or value represented by the perforation or combination of perforations in the column is passing through printing position, a circuit will be closed through the printing magnet 86 under control of the distributing commutator |3| to actuate the printing'hammer 63 to effect printing of the character. As shown in Fig. 13, all of the four segments corresponding to the index position 9 on the card (one in each group) are connected to each other by bus wires |33 and are, in turn, connected by a wire |34 td a contact ring |35. In like manner, all of the segments |30 corresponding to the index position 8 on the card are interconnected and are connected by wire |36 to another of the contact rings |35. In this manner, all of the segments |39 representing a particular index position on the column of the cardare interconnected and connected to one of the several contact rings |35. A separate brush |31 cooperates With each of the contact rings |35. Each of the brushes |31 is connected to a separate one of the analyzing brushes 3 associated with the index'positions l, 2, etc. to 9 on the card.

Referring to the card in Fig. 7, the rst column is shown as having perforations in the position and in the R position. f

With the card in position for reading and the carriage rack 'l in its restored position, contacts |03 are again closed and magnet reenergized to close contacts Y||2 and ||3. Also with the rack bar 32 standing in position at the right and being lheld by. the escapement pawl 53a, which pawl ywhen in such position permits contacts |38 to close, (see also Fig. 4a). -The following circuit will now be closed: from the left side of the line H6, through electromagnet |39, contacts CCI which according to the timing diagram (Fig. 12) are closed at the beginning of an analyzing cycle, contacts |30 which are closed when the rack 32 is standing still, upper contacts |09, which are closed as long as the rack 32 is out of its home position at the left, contacts ||2, now closed, wire |20, back to the line |2|.

f/qthe sensing brush 3a which is in register with the R index position on the card which as we have seen in Fig. 7, is perforated in column Current then passes through magnet R, Wire |43, Wire |44 and back to the line |2|. The energization of magnet R closes contacts |45 to permit closure of the circuit through the printing magnet 86 and through the second perforation in the particular column on the card at a time depending upon the condition of the contacts CCI, and alsoV the closing of the circuit through -the particular segment 30. For instance, ac-A cording to the timing diagram, contacts CCI are closed during thatvportion of the sensing and printing cycle, when the rst nine type elements are passing through printing position.

During this portion of the cycle, as each type element passes the printing position, a corresponding one of the segments 30 will be passing over brush |32. According to the timing diagram, the segment |30 connected to the 9 posi,- tion on the card, rst passes over the brush |32, then the segment representing the 8 position passes-the brush and so on. In the present instance, when the segment |30 corresponding to position on the card passes over the brush |32, a circuitwill be completed fromthe line H6, through contacts |40, contacts CC|0, wire |42, brush |32, the particular segment |30, and, through the interconnection shown in Fig. 13, across to the contact ring |35 corresponding to the position on the card, then through the corresponding brush |31, sensing brush 3az which is in register with the perforation in the card, then through contact plate 4, wire |46, printing l magnet 86, contacts |45, contacts CCI, wire |44, back to the line |2|. 'I'he energization of the printing magnet 86 at this moment, will as we have seen, referring to Fig. 3, cause the printing hammer 63 to actuate the particular type element v59 to print the character represented by the particular combination of perforations which, in the present instance, is the alphabetic character A.

After the completion of the printing and at the end of the first zone portion of the printing cycle, contacts CCI open as shown in Fig. 12. Now during the second zone portion of the cycle another one of the segments |30 associated with the I index position will cooperate with brush |32 but will not close a circuit through the printing magnet, as the magnet -X has not been energized and has not caused closure of contacts |41, although contacts CC2 are now closed. Similarly, during the third zoning portion of the cycle, the magnet O has not been energized and contacts |48 are open, so that although contacts `CO3 are now closed, the current cannot pass through the printing magnet.

However, during the fourth zone, when the contacts CC4 are closed, the current would pass through the printing magnet 86 to print the numeral in the absence of provision to prevent this. In the present instance, the operation of,

the printing magnet under control of any one of the zoning magnets R, X or O will, by operation of the parallel arms 68 in operating the printing hammer 63, close the normally open contacts |49. This is done by the projection |50 carried by the arms 68 (see Fig. 3). The closing of contacts |49 in Fig. 11 closes a circuit through electromagnet |5| as follows: from line ||6, wire ||1, wire |52, magnet |5|, contacts |49, back to the line |2|. Contacts |49 are closed momentarily during lthe printing operation and the circuit through magnet |5| will be held after contacts |49 open, by a shunt circuit which passes through contacts |53 and contacts CC5 which latter are closed throughout the printing cycle. The energization of magnet |5| open contacts |54 so that now when contacts C04 are closed for the fourth zone portion of the printing cycle and the sensing brush 3a2 would otherwise tend to close a circuit through the segment |30 to energize magnet 86, the open condition of contacts |54 prevents this and thus prevents printing of the numeral l.

After the completion of the printing under 4control of the perforations in the first column on the card, the escapement 53 will operate to release the rack 32 to permit the card to be fed one column to the left to bring the second column into cooperation with the analyzing brushes 3a. The escapement is effected by energization of magnet 51 as we have seen. This magnet is energized by the closing of contacts CCS which in Fig. 12 takes place at the end of the cycle, and after the completion of printing. This permits energization of magnet 51 throughthe following circuit: from the line ||6, through magnet 51, contacts CC9, contacts |4| which are still closed, wire`l42', contacts CC8 which are still closed, wire |20 back to the line |2|.

While the escapement is taking placeunder' control of magnet 51, contacts |38 are open and are no-t closed again until the carriage has moved and brought the next column into register with the analyzing brushes/."5-l In Fig. 11, it will be seen that contacts |38 are in series with contacts CC1. Contacts CC1 according to the diagram (Fig. 1,2) close for a short period just before the nextprinting cycle commences. If the. escapement has not been completed before contacts CC1 close, then mence, analyzing of the the printing control circuit through magnet |38 will not be reestablished forr that cycle. If, on the other hand, the escapement has been completed and contacts |38 have reclosed, then closure of contacts CC1 will reestablish the circuit throughv CC1, if the escapement has not been completed, then the 4analyzing and printing cannot commence during the following printing cycle but must skip that cycle and commence in the next cycle later. Having escaped to the second column now, we ind a perforation in the R position and in the 3 position. The R perforation will again energize magnet R (Fig. 11) and the' perforation in the 3 position will close the circuit as before through the printing magnet 86 at a time with respect to the'operation of the type wheel 60, to print the alphabetic character C. After the next escapement, to place the third column in analyzing position, we nd that the zoning perforation is in the X position. A

This will close a circuit through the magnet X as follows: from the line I6, through contacts |40, contacts CCIU, wire |42, sensing brush 3a3, zoning magnet X, lines |43, |44, back to the line |2|.

Magnet X closes contacts |41. Now, during the first zone portion of the printing cycle, no printing circuit will be closed but during the second zoning portion, contacts CC2 will close so that the print- -ing circuit will be closed through contacts |40,y

CC|0, brush |32, the particular segment |30 corresponding to the 4 index position, then through 4contact ring |35 also correspondingy to the 4 index position, the brush |31, corresponding sensing brush 3a, contact strip 4, wire |46, printing magnet 86, contacts |41, contacts CC2, wire |44, back to the line. 'I'his energization of magnet 86 takes place in time to effect the operation of the type element 59 representing the alphabetic character'M to print this character.

If there is'a perforation in one of the numeral index positions on the card but none in either the X or R or O positions, then none of the contacts |45, |41, |48 will be closed and the circuit through the printing magnet 86 will not be closed until sometime during the fourth zone portion of the printing cycle. During this portion of the cycle, contacts CC4 are in closed position and when the particular segment |30 corresponding to the position of the perforation reaches brush |32, a circuit will be closed through the corresponding one of contact rings |35, contact strip 4, magnet 86, contacts |54, contacts CC4 to the other side of the line. This will print the vnumeral.

If a perforation appears in the 0 index positions on the card, the resultant energlzation of electromagnet O will close zone contacts |48, and also contacts |55. Referring to Fig. 13 it will be seen that there is only one O segment |30 which is'the last segment on the commutator. Now when this segment reaches brush |32, the circuit through the segment to the O contact ring |35 will pass through contact |55, wire |46, magnet A86, contactsV |54, contacts CO4, to the other side Therefore, by providing contacts |38 and contactsv operation will cause the contacts |54 to be opened so that when the fourth zone portion of the'cycle is reached, no printing can take place.

If there is no perforation at all in a column, y

for instance, between the end'of al word and the beginning of another word, escapement of the card carriage will take place as usual when the contacts CC9 close.

This will go on column by column until all of the columns on the card have been analyzed and printing effected at the heads of such columns.

If several columns are to be skipped, a skip bar,

95 (Fig.'4) will bring this about as has been described.

After the card has been completely analyzed and the last escapement takes place, the rack bar 32 will cause closure of contacts |04. At the same time, card grippers 3| will be opened as described to allow the card to drop into the receiving hopper |00. The closure of contacts |04 reenergizes magnet |08, opening the upper contacts |09 so as to interrupt the circuit through contacts |38 and CC1 and magnet |39. This will prevent analyzing and printing operations during the next cycle of the machine while the new card is vbeing fed in. Contacts ||0 are also closed byk magnet |08 so that as soon as contacts C06 close,

' a circuit through magnet 30 will be reestablished through contacts |28 which are being held closed by magnet |21, then through contacts ||3 which are closed by reason of the energlzation of magnet through contacts |03 now in closed position under control of the rack 1, then through contacts ||0 which have just closed as we have seen, then through contacts |24, which are held` closed by magnet 8, then back to the line |2|. The energization of magnet 30 at this time will again close contacts 9| to energize motor |'4 and also to cause operation of the clutches I1, 21 to cause the next card to be fed to the machine, and

the movement of the rack bar 32 to the'right where the grippers 3| will grip the new card as before. After the rack 1'hasf delivered its card and returned to its normal position to the right,

analyzing of the rst column on the card will commence as previously described and themachine will again proceed column by column to analyze the perforations and effect printing.

If it is desired to stop the machine at any time, this may be done by depressing the stop key |56 to open contacts |23. This will break the circuit through electromagnet ||8`and permit the contacts |24 to open. This, in turn, breaks the holding circuit through magnet |21 so that when contacts CO6 again close, no circuit will be closed )through magnet 30. Motor i4 will therefore not be energized to operate the feeding rack 1 orfthe rack 32. If the supply magazine 2 becomes empty, releasing card lever 0|, convcolumn until work upon that card has been completed, at which time the rack bar 32 has reached the end ofits movement toward the left where it will close contacts |04 and the 4card which has been carried.` out will be deposited inthe receiving hopper |00. Motor 13, of course, continues to operate until the switch |01 is manually opened.

'I'he opening of contacts |24l upon deenergization of magnet ||8, and the resultant deenergization of the holding magnet |21 causes contacts |28, |29 to open and contacts |23 to close.

To restartthe card feeding operation now, the

start key ||4 will be'depressed closing contacts ||5 and reestablishing the circuit through the magnet ||8 to close contacts |24. Now, when contacts CCG are closed, the magnet 30 will bey come energized as previously describedA to cause operation of the motor I4 and closing offthe clutch l1, 21.

Figs. 10 and 10a show the wiring diagram of the machine arranged to operate with the ilve rows of sensing brushes 3a, 3b, etc. shown in Figs. 4 and' 4a. The general control of the machine is the same as disclosed in connection with Fig. l1. For instance, the machine is started by closing switch |01 (Fig. 10a) This causes the motor 13 to operate. With the rack bar 32 standing in the position of Fig. 4 with contacts |04 closed, a circuit will be I,completed through magnet |08 to close contacts ||0 and the lower set of contacts |09. Contacts |03 (Fig. 4a) are also closed so that magnet is energized to close contacts ||2and ||3. 'I'he start key ||4 will now be depressed toclose contacts 5 and this will close a circuit through magnet ||8 as previously described and the circuit throughnthis magnet will be held through contacts |22. Now' when contacts CCS close, magnet 30 will be energized and will cause a card to be fed to the sensing brushes as described.

Assuming now that a card is in position to be throughout .the analyzing portion of the cycle, l, then through wire |42 to commutator brush |32, 1 and also branching over to the contact strips 4a associated with the five rows of brushes. If there is a hole in the O or X or R positions in the card in the first column. the current willpass through the particular brush cooperating with that hole and through the particular magnet Ra or Xa.

or oa, and thrugh wires |43, m, back to 'the other side of the line |2|.l

If there is a perforation in one of these three index positions in column |1. then the particular brush 3b cooperating with that perforation will close a circuit through its magnet Rb or Xb or Ob. This is so also for the brushes' of rows 3c.

'3d andl 3e and their respective vmagnets Ric,

Xe, Oc, etc.

In Figl0, the printing magnets 86a. 86h, 86e,

86d, 80e are normally disconnected from wires |46a, etc., whereas in Fig. 1l magnet 86 is shown permanently connected to wire |46. In Fig. l0 magnet 86e is connected to wire |46e by a plug connection, |51. To associate printing magnet 86el with its corresponding sensing brushes 3e as is the case in Fig. 11, a plug connection |58 may be used. The return circuit for magnet 86e is through contacts |54e, contacts |45e or |41e or |48e, through the cam contacts CC3, or CC2. or CCI. In Fig. 7 the first column on the card is shown as being perforated in the R and positions. Assuming that the column on the card which is cooperating with the row of brushes 3e is punched in these same positions, it willbe recognized that the circuit which was traced to the several contact strips 4a will pass through the sensing brush corresponding to the R position, then through magnet Re and back through wires |43 and |44 to the other side of the line. This will close contacts |45e.

We have seen that contacts CCI are closed for the first zone portion of the sensing and printing cycle according to the timing diagram of Fig.

12, so that-now'as the commutator |3| and conf tact rings |35 turn synchronously with the operation ofthe several printing wheels 60, the circuit which we traced as far as brush |32 will pass through the segment corresponding to the .index position; (there are, of course, four such segments and as the contacts CCI are closed in the first zone portion of the printing cycle the rst of thesegments will carry the current from brush |32 across to the contactring |35 of the i,

index position) from here the current passes through the corresponding brush |31, to the analyzing brush 3e, contact strip 4, wire |46e,-

plug connection |51, printing magnet 86e, plug connection |58, plug connections |66,'|61 and contacts |54e, contacts |45e, contacts CCI, to the other side of the line. This will control printing by the particular type element 59 on type carrier 60e, to print the particular character which in the present instance would be the alphabetic character A. This will go on for each successive column on the card in the manner described in connection 'with Fig. 11.

With the plug connections |51, |58, the printing of a character will be effected at the top of the column containing the perforations. However, the printing magnets 86e, etc. may be connected with other sets of sensing brushes 3a, 3b, etc. so that where one set of sensing brushes 3a, etc. analyze perforations in a particular column, the printing of the character represented by the perforations may be effected in some other column,

that is, referring to FigsA and 4a, the brushes 3a Aeffect printing from the wheel 60e. This plugconnection comprises a plug wire |59 connected vfrom the plug socket |60 to plug socket |6| associated with printing magnet 66e. Plug socket |62 also associated with printing. magnet 86e is plugged'to socket` |63. This will effect printing in the manner shown in Fig. 8. There the perforations are shown in the columns which will be analyzed by the row of brushes 3a, while the printing of` the data represented is effected at the top of the columns associated with the printing wheel 60h. In Fig. 10, the plugging is such that the data represented by perforations in the columns which will be analyzed by the row of brushes 3d willv be printed at'the tops' of the columns associated sensing brush 3d, through magnet Rd and back to the other side of the line. This will close contact |45d. Now when the rst segment |30 associated with the index position registers 'with brush |32, the current will pass over into the corresponding contact xing |35, brush |31, corresponding brush 3d, contact strip 4, wire |46d, plugV connection |59, printing magnet 86e, plug connection |62d, plug connection |10,' contacts |54c, plug connection 1|, contacts |45d, which are now closed by reason of the energization of magnet Rd, then through contacts CCI to the other side of the line. i

This then, energizes magnet 86o to actuate the printing hammer associated with printing wheel 60o at the proper time in th'e cycle to eiect print- Ving of the particular alphabetic character which in the present instance is the letter A. In connection with Fig. 11, we have seen that it is necessary to prevent operation of the printing magnet later inthe printing cycle under control of the perforation through the numeral index position, ,(in the present instance the position) which would normally cause printing of the numeral in the fourth zone portion of the printing cycle when the contacts CC4 are closed. In Fig. l1, this is effected by the energization of magnet |5| when the rst printing operation is effected to open contacts |54 so that later inthe cycle,

when contacts CC4 close, the printing circuit cang not be closed. In connection with the printing which we have assumed under control of the plugging |51, |58 in Fig. 10, this'prevention of therepeat printing is effected by the opening of contacts |54c.

In the present instance, the operation of the printing magnet 86e and printing from a corresponding type wheel 60e will eiect closure of contacts 49e (Fig. 10a) in the same manner lthat contacts..|49 were closed ln Fig. 3. This energizes magnet |5|e through a circuit from the left side of the line through'wire-I52, magnet |5| e, wire |64, contacts |49e, wire |65, wire |44 and back to thc other side of ,the line 2|. Magnet |5|e then causes contacts 54e to open as soon as any printing is effected by energization of magnet 86e. Since magnet 86e is connected by plugging |51, |58 with the sensing brushes 3e, the contacts |54c will be plugged by plug connections |66, |61. But `where the printing under control of brushes 3d when printing is effected from the type wheel 60e as we are assuming it is,-the contacts |49c will close to energize magnet |5|c which, in turn, will open contacts |54c. been effected throughu'nagnet 86C, when contacts CC4 close,l the circuit cannot again be closed through lthe printing magnets 86a during the fourth zone portion of the printing cycle because 'of the open condition of contacts |54c. If there had not been any other perforation in the coliunn than the perforation then, of course, printing would not have been effected to print the letter A and as the printing wheel.6,0c is operating through the fourth zone portion of the cycle, the circuit through the particular segment |30 4will energize the printing magnet 86c through plug connection |62d, socketll63, socket |68, plug con- Thus, after printing has tacts CC4. The circuitthrough contacts CC4 is `through contacts |40, magnet |91, contacts CC4 to line I2 I v i It will, of course, be recognized that instead of plugging to the printing magnet 86e, any other of the printing magnets could be plugged in to In Fig. 9, a card is shown in which a perforavtion is shown in the X position in the first column. 'Ihe setting of the machine by plugging is such that the printing of the data represented by the perforations inthe next succeeding columns is printed at the tops of different columns as shown. If it is desired to print the data represented bythe perforations, at the top of the4 corresponding columns, then there would not be the X perforation alone in the first column, This column then could, of course, be used for ordinary data by having either a single perforation in one of the numeral positions or a perforation in either the O or X or.R position along with a perforation in one of the numeral positions.

AIn the diagram of Figs. 10 and lOa, the sensing brushes 3b are shown so' plugged as to effect printing through the printing magnet 86h and printing wheelv 60h, that is, at the tops oi' the corresponding columns, or through magnet 86a and printing wheel a, that is, at the tops of different columns.

The selective printing, is controlled through switches |13a, I13b, |13c, etc., which are con` trolled by electromagnets I14a, |14b, |14c, etc. (Fig. 10a). A switch blade I13a-is permanently connected to plug socket |1311 and is normally in contact with contact I13a2. Energization of magnet |14a will move the blade into cooperation with contact I13a3.

If the X position alone is not punched in the first column, then the datarepresented by the perforations will be printed at the tops of the columns containing the perforations. is punched in the first column, then the printing will take place in some other position on the card depending upon which of the printing magnets 80 is Aassociated by plugging with the analyzing brushes. f

Contact4 |41b (Fig. k10) is connected by plug connection |15 to wire |16. If the printing is to be controlled alternatively by magnets -8Iib and 86a, then these two magnets will be connected by plugging to the switches |13b as shown in Figs. l0 and 10a., The corresponding contacts |54b and |54a will also be connected by plugging as shown to certain of the switches |13b; Now

if the first column of the several columnsl which are to be analyzed by brushes 3b has an X perforation only, asin the case of the rst column (Fig. 9), that perforation win be sensed by the X brush cooperating with the strip 4a to energize magnet Xb in the usual manner: 'This magnet will close contacts |41b' so that when, during that cycle, contacts CCI I close at\the time shown in Fig. 12, a circuit will be closed through. mag

net |14b, from the left side of the line, through If an X alone wire |52, magnet |14b, wire |11, contacts I54b',

4wire |18, plug connection |15, contacts |41b',

wire |18, contacts CCII to the. right side of the line. Magnet |14b will shift all of the switchesV `line through wire |52, magnet |14b, contacts |14b2, wire |19, contacts |09a, back to the right side of the line. This circuit `will be held until contacts |09a open after the completion of the printing operations upon the card. As the columns of the card are now successively analyzed,

a perforation in any one of the positions R, X or O will, in the usual manner, close their respective contacts |45b, |41b, |48b to determine which zone portion of the analyzing cycle is to be effective for printing.

In order to prevent a possiblerepetition of the operation of the printing hammer during a subsequent zone portion of the same printing cycle, the respective control contacts |54b, 54a will be connected by plugging to switches |13b to provide the circuit which we have just traced.

y If there has been printing in the first or'second or third zone portion of the printing cycle, then contacts |54a will have opened prior to the beginning of the fourth zone under control of magnet |5|a in the manner previously described.

But if no printing had been effected inthe first or second or third zone portions of the printing cycle, then during the fourth portion of the cycle, when contacts CC4 have closed, causing closure of contacts |9Iia, |96b, etc. the current will( pass through switch |54a, then by way of plugv connection |88 to the side of its respective switch |13b which as we haveseen has been closed then through plug connection |89, back to wire |a, and through contacts |8617 to the other side ,of the line.v Such a circuit will effect printing of a numeral during the fourth .zone portion of the printing cycle.

y Assuming now that the first column analyzed by the brushes 3b does not have a perforation in the X position alone, but has a perforation in any 'one of the positions R, X and O and also a perforation in one of the numeral positions, then, 'although -the contacts H112' may have closed, the

0r, if there is no perforation in one 'of positions R, X or O then, during the fourth portion of the printing cycle, the current upon reaching the plug socket |84 will pass through wire m5, plug connection |86, the respective switch |131, plug connection |93 to one side of contacts |5412', through said contacts to plug connection i913 to the respective switch |1311 and back by plug connection it@ to and through contacts ittb now closed under control of contacts CCd to the other tions.

Sometimes, because of code arrangements, the X position is not available to determine whether printing shall be effected on one part of the card or another. For this reason, the system'is capable .of employing either the X or the R position to effect this selective printing position control. If the control is to be effected through a perforation in the R. position alone, then, instead of making the plug connection |15 between contact point |41b and wire |16, this plugging would be effected between contact |45b' and wire |16. Now, if the rst column to be analyzed by the brushes 3b contains a perforation in the R position only, contacts |4512' will be closed instead of contacts |l1b as previously assumed. Now, when contacts CC|| close a circuit through the particular magnet ma, mb, etc. will be ciosea as described in connection with the X position hole.

If printing is not to be shifted under control of an X perforation only or an R. perforation only, and the first column analyzed contains an X position perforation in addition to a perforation in one of the numeral positions, the printing of the corresponding alphabetic character will take place during the second portieri of the printing cycle and, since this causes closure of contacts Ilsb, the Icontacts |54b', will be opened by magnet |15|b so that when contacts CCI close during the third portion of the printing cycle, as indicated in Fig. 12, the circuit through magnet |1lb will be open aosaocs at the point |5412' so that the switches |131 cannot be shifted. t v

In Fig. l0, where five sets of sensing brushes 3a,. 3b, etc. are employed, it will be noted thatthere 4 are ve corresponding zero rings |35 which are of insulating material throughout their circumferences excepting at certain timed segmental spots O which cooperate with the zero brushes |31 at the time in the cycle that the zero spot |30 is in cooperation with brush |32. These five spots O' are wiredtogether and connect to the zero segment |30. Each zero printing` control circuit extending to a brush |31 is provided with a separate contact |55a., |55b, etc. operated by its respective zone magnet Oa, Ob, etc.

It will be seen that by appropriate plugging, any one of the rows of brushes 3a, 3b, etc. may be connected to any one of the five of the printing magnets 06a, 86h, etc. to effect printing upon any desired portion of the card.

As shown in Fig. 1, the plug connections are made on the plugboard |95.
