The machine comprises punch unit A and secondary clock unit B electrically connected by wires in cable C, as shown in Fig. l.

The pimch unit A is of the type adapted to perforate the card columns one after another.

The machine has several different uses but for illustration assume it is utilized for ordinary i pay-roll recording. The card T is a tabulating card, shown in Fig. 2, and has from left to right, columns assigned to the department number, man number, the date, the start time, the finish time, and elapsed time. Each card is identified by name and number. When a workman starts work, he takes his card from a card rack and hands it to the punch unit operator who inserts it in the punch unit.

The department, man number, and date may be prepunched or the operator may manually operate the machine to punch in this data. In the present case, assume the operator depresses the keys to punch the department and man numher and that the date is automatically punched under pattern card control. When the date punching is completed, the first of the start time columns moves into punching position and the start columns are then automatically perforated, according to the time, under selective control 0! the secondary clock unit B. Following the punching of the start time,- the first of the finish time columns moves to punching position. The machine automatically skips these columns and the card is automatically moved to its last column position to be removed. The card punched with the start time may then be returned to the employee to be replaced in the card rack. When the workman finishes his job, he again hands the card to the punch operator who places it in the punch unit, depresses a finish key, and then operates the space key to feed the card to the first date column whereupon the pattern control automatically advances the card to the start column. Here mechanism comes into play to automatically skip the start columns and bring the first finish column of the card to punching position. The finish columns are then automatically time punched in code and the card moved to last column position to be removed The completed card may be retained by the punch operator to be sent to the accounting department.

The time control for selecting the punches will first be described in detail. Referring to Figs. 3

and 5 to 8, clock unit B includes the usual mag-" net I 0 which receives an impulse each minute from a time system.

When the magnet receives an impulse, it is energized to rock its armature H counterclockwise (as viewed in Fig. 5). The armature is pivotally connected to a bell crank 52 which is rocked clockwise by aforesaid action of the armature. A spring l3 connected to screw l4 fixed to hell crank 12 resists rocking of the armature and bell crank Pivoted to the bell crank at l 5 is an actuating pawl it which at its rear is connected by a light spring H to the bell crank. The forward end of the bell rank is formed with a pawl nose [8 and the forward end of pawl l6 similarly formed with a pawl nose I 9. Both these pawl noses coact with a disk 2% having sixty teeth. Also coasting with the teeth of disk 28 is a pivoted holding dog 22, constantly urged towards the disk periphery by a spring 23.

When bell crank (42 rocks clockwise, as abov described, pawl nose i8 is lifted out of engagement'with disk 28 while pawl nose EB moves upwardly and drags along the periphery of the disk 20, being held in engagement with the disk by light spring ll, until nose 1% enters the tooth notch above the one previously engaged thereby. Now when the magnet E8 is deenergized, spring l3 rocks bell crank 52 counterclockwise, causing pawl nose 19 to move disk 26 clockwise and pawl nose It to reengage the disk to prevent over-running of downwardly.

the latter beyond a single tooth space. Holding dog 22 impositively latches the disk against rotation except by downward movement of pawl nose In above' manner, disk 28 is advanced one tooth every minute. To the side of disk 20 is fixed a cam 25 having ten teeth, each representing a six minute interval. A cam follower 28 freely rotatably mounted on a shaft 21 coacts with the teeth of cam 25.

Rigidly secured to the follower 26 is a member 25' carrying a dog 28 en aged with a disk 29 having twenty teeth. Member 26' also carries a pivoted actuating pawl 30 for engaging disk 29 and which is biased towards the disk by a light spring 3| between the pawl and said member. The disk is normally locked by a tooth 32 on a pivoted arm 33 which is connected by a spring 34 to member 28'.

As cam 25 rotates, follower 28 rises against resistance of spring 34 and through member 26' lifts dog 28 out of engagement with disk 29 while dragging pawl 30 upwardly out of one tooth of the disk to engage the next higher tooth. Pawl 30 h% an inclined surface 35 which as the pawl rises engages the right side of a stud 38 (as viewed in Fig. 5) at the outer end of locking arm 33 and is cammed outwardly until it passes the stud, after whichspring 3| moves the pawl inwardly. When follower 26 drops oil apeak of cam 25, spring 34 forces the follower 26, member 26', and pawl 30 During this downward movement of the pawl, the cam surface 31 of the pawl engages the left side of the stud-36 and cams the lever 33 downwardly and away from disk 29, thus releasing tooth 32 from the disk and permitting the pawl to advance the disk one tooth space.

In above manner, cam 25 every six minutes moves twenty-tooth disk 29 one step. In onetion while the twenty-tooth disk 29 isin motion,

the high point of a tooth of cam 25 engages a lower spring blade 39 (see Fig. 3) separating it from an upper spring blade 48 to open normally closed contacts 4| carried by the blades.

This action occurs at each sixth minute impulse and the manner in which the opening of contacts 4| prevents starting of the time punching operation will be later explained in connection with the circuit diagram. When the sixth minute impulse transfer movement is completed, the high point of cam 25 moves suillciently to disengage lower contact blade 39 and thus allow contacts 4| to close. The time punching operation may then be permitted to take place.

Fixed to the side of disk 29 is a two point cam- 43. Held against thiscam by a spring 44 is a follower 45 (Figs. 6 and 8) which is fast to one end of shaft 21. Rigidly carried by shaft 21 at its opposite end is a member l6 (Figs. 6 and 7) Provided with an actuating pawl 41 coacting with a twentyfour tooth hour disk 43. In the same manner as cam 25 causes step-by-step movement of disk 29, cam 43 through follower 45, member 46, and pawl 4i causes a movement of disk 48 through one tooth space each time follower 45 drops oil a point. As disk 28 makes half a revolution each hour, cam 63 fixed to the disk 29 will traverse one of its two steps past follower 45 once per hour. Follower 35 will in turn cause hour disk 48 to advance one tooth per hour.

The mounting of disks 20, 29 and 48 is as follows: Disk 29 has'a round hub sleeve 49 rotatably mounted on a stationary shaft 58 carried by the frame. Sixty tooth disk 28 is rotatably mounted on hub sleeve 49. The round sleeve terminates in a non-circular portion 52 to nonrotatably receive a collar 53 of insulating material. To opposite sides of collar 53 are fixed brush holders 54 and 55 (see Fig. 6).

The twenty-four tooth disk 48 also has an angularhub portion 52' (Fig. 7) rotatably mounted on stationary shaft 50. On this hub portion is secured the insulating collar 53' to which is secured a pair of brush holders 58 and 51.

- Each brush holder carries a pair of brushes 58, one brush diametrically opposite the other.

Surrounding brush holder 54 is a stationary commutator having a semi-circle of ten equally spaced contacts 6| and a semi-circular metal band 62 forming a common return. During one half a revolution of brush holders 54, one of its brushes 58 is wiping the common return 62 and .the other brush 58 successively engages contacts 169 while on the other half of the revolution of holder 54, the function of the two brushes is reversed. 1 '2 Similarly brushes 58 of brush holder 55 are arranged to coact with a commutator having ten contacts 63 and a common return 84.

In a similar manner, brushes 58 of brush holder 58 coact with a commutator having a semi-circle of twelve contacts 65 and a common return 65 and brushes 58 of brush holder 51 coact with twelve contacts 61 and a common return 68.

As explained above, sixty-tooth disk 28 moves one step each minute. Under control of ten step cam 25 fixed to disk 20, the twenty-tooth disk '29 is advanced one step every six minutes. Ac-

cordingly, the brush holders 54 and 55 which rotate with disk 29 are moved one step every six minutes. Under control of two point cam 43 fixed to twenty-tooth disk 29, the twenty-four tooth disk 48 is advanced one step every hour.

Accordingly, brush holders 58 and 51 which rotate with disk 48 move one step every hour.

The brushes 58 of brush holders 54 and 55 and the coacting commutator contacts Cl and 88 form the minute punch selectors, while the brushes of holders 56 and 51 and-the contacts 85 and 81 wiped thereby form the hour punch selectors.

Reference to the circuit diagram (Fig. 9) shows how the minute and hour punch selectors are arranged for properly selecting the punches in accordance with minutes and hours.

of the minute selector, contacts 6| control the punching of the tens denomination of the minutes while contacts 63 control the punching of the units denomination of the minutes. Since the brushes coacting with these contacts step along at six minute intervals, the reading of the minutes is by six minute increments; thus, 00, 06, 12, 18, 24, 30, 36, 42, 48, and 54. At the beginning of an hour, the brushes of brush holders 54 and 55 are concurrently sensing a pair of contact .points 61 and 63, both connected to a 0" punch operating control. After six minutes have elapsed, the brushes step along in unison to the next pair of contacts 61 and 63, respectively connected to the O punch operating control and the 6 punch operating control. At the next six minute interval, the brushes step to a pair of contacts 6| and 63, respectively connected to the 1 punch control and the 2 punch control. Thus, by a combination of the contacts GI and 63 in each position of the brushes 58 of the minute selector, a selection is made of the punch controls for punching one of the six minute intervals, 00, 06, 12, 18, etc.

In a similar manner, the hour punch selector functions to select the controls for the hour punching. The hours are to be punched as 1, 2-12. Contacts 85 control the punching of the tens order and contacts 61 the punching of the units order of the hour time.

per hour and concurrently sense a pair of contacts 65 and $1 to select the punches according to the hour. Thus, at 6 oclock, the hour selector brushes feel a pair of contacts 65 and 81, respectively connected to the 0" punch control and the 6 punch control. At 10 o'clock, the brushes concurrently sense a pair of contacts 85 and 81, respectively connected to the 1 punch control and the 0 punch control.

In order to fully explain the manner in which the hour and minute punch selectors of the clock unit B coact with the punch unit A to cause the time to be perforated in the tabulating card, a brief description of the essential parts of the punch unit will be given with reference to Figs. '1, 2, and 4. The punching unit is of the type shown in Patent No. 1,914,263. Punches 15 are arranged in a single column extending transversely of the machine, as indicated in Fig. 1, with each punch corresponding to a different one of the index point positions of a column of the tabulating card T.

Depression of a key 16 rocks a connected bell crank 11 to advance an interposer bar 18 above an alined punch. When hammer 18 is depressed,

. it-engages interposer bar 18 to in turn depress erator or may, be automatically depressed by the action'of control magnets 82. Energization of a magnet 82 attracts its armature 88 to rock a lever 84 downwardly. The lever 8| is pivoted to a key 18 and the lever when rocked downwardly depresses the key to cause punching in the same manner as upon manual operation of the key.

The card feeds the width of one column space at each punching operation. The feeding means is under control of an escapement mechanism which is of the type dizcloscd in Patent No. 1,426,223. Briefly, the card rests on frame surface 85 and is engaged at the right side (as seen in Fig. 4) by a pusher 88 and at the left side is engaged by an abutment 81. Both the pusher and the abutment are carriedby a rack bar 88 mounted to slide in the frame. The pusher, abutment, and rack bar may for convenience be te-'nied the card carriage or feeder. As shown in Fig. 2, the teeth of rack bar 88 are engaged by a pair of pawls 88 and 80, the former normally free of the rack teeth 91 of the bar and the latter normally engaged with the rack teeth. A lever 82 fast to shaft 93 is connected to both pawls to operate them in reverse directions. The shaft 93 carries a bail M (Fig. 4) underlying all the interposers 18 so that depression of any of the latter upon a punching operation rocks the bail and thereby shaft 93 to cause lever 92 to lift pawl 98 out of engagement with the rack teeth 9i and to lower pawl 89 into engagement with the rack teeth. When the pawl 90 is released, it shifts un: der theinflucncc of spring 85 to a point above the next rack tooth 96.

After the hole has been punched in the card, interposer 18 and bail 9| rise and shaft 83 rocks clockwise (as viewed in Fig. 2) to release pawl 8% from the rackteeth and to rock pawl downwardly on top of said next tooth 91. A spring motor 96 now acts through its pinion 81 meshed with the teeth 98 on the lower edge of the rack bar 88 to advance the bar until it is stopped by the seating of pawl 98 in said next rack tooth 9E. The above described movement of the rack bar 88 for one tooth space advances the card transversely one column at a time.

In the present case, the card is inserted in the machine by the operator. This is done when the card feeder is in the position shown in Fig. 1

by placing the card on surface between the pusher 86 and abutment 81. A thumb piece I80 (Fig. l) on a bar I01 fast to rack bar 88 is then engaged by the operator to move the card feeder to the extreme right, the escapement pawls freely permitting retraction of the rack bar. In such movement, teeth 88 of the escapement bar operate pinion 91 to energize spring motor 96. In its' retracted position, the card feeder locates the card in the position shown in Fig. 4 with its first, or extreme left hand column under thecolumn of punches 15, each index position or hole receiving position of the card column being directly beneath a different one of the column of punches.

The punch operating means is of the type shown in Patent No. 1,878,930. Briefly, hammer 19 which depresses the punches is operated by a linkage I02 connected to the armature ill; .of punch magnet IN. The magnet is energized whenever an interposer is moved forward to operat'ive position.

For this purpose, a bail I05 engages all the interposers so that when any of the latter are advanced, the bail rocks counterclockwise (as viewed in Fig. 4) andlifts a link I88 to close a pair of contacts I01. When the'punch operating linkage .182 is actuated by the energization of the punch magnet, 9. lug i118 .on the linkage kicks the link I06 away from contacts 101 permitting the latter engagement with the rack teeth 9 I to open and break the circuit through the punch magnet.

A column selector is provided in the punchin machine. This selector includes three brushes carried by bar IOI which is fixed to the escapement rack 88. The brushes move along a stationary column commutator HI fixed to the punch machine frame. The contacts II2 of the commutator bar (see circuit diagram, Fig. 9) are spaced along the bar at distance equal to the width of a card column. Thus, when the card is fed one column space, the two upper brushes IIO will move from one contact II2 to the adjacent one. The lower brush moves along a common return bar I40. The operation of the column commutator efiects a selection of the card columns to be perforated under clock control while the minute and hour selectors control the digits to be punched in the selected column.

In addition to the digit keys '66, there is the usual key H4 operation of which causes the card. feeding means tofeed the card several columns under control of a skip bar H5 which is carried by the side of the escapement rack (Fig. 2). The primary purpose of the depression of the X key EM is to cause column skipping mechanism to take effect and incidentally to cause the punching of an X or eleventh index point position of the card column under the punches.

When the X key is depressed, in a known manner, it moves a lifter arm I I6 forwardly. The forward end of arm H8 is beveled to coact with the upper edge of skip bar I I5 to elevate the arm when it is moved forwardly. The arm passes beneathescapement pawl 90 so that the rise of the arm when moved forwardly, lifts pawl 80 out of Spring motor 96 thereupon is free to actuate the escapement bar 88 and the card feeder carried thereby to the left (as viewed in Figs. 1, 2, and 4) The card feeder advances until a depression I I 8 in the skip bar reaches the lifter arm H6 whereupon the latter drops and the pawl 90 reengages the escapement bar to stop further advance of the card. For further details of the skip mechanism, recourse may be had to Patent No. 1,426,223.

A pattern card section D of the type disclosed in Patent No. 1,878,935 is provided in the punch unit. The pattern card is fed by the escapement mechanism in unison with the feed of the card T in the punching section. The operation of the pattern card section will be briefly explained later in connection with the circuit diagram.

The punch unit is provided with a motor M adapted to automatically feed cards one at a time from supply stack I I9 and with automatic ejecting mechanism including a card flipper I20. However, for the purposes of the present invention, the automatic feeding and ejecting mechanism is not necessary and is disabled by opening certain switches.

The coaction of'the punching unit A and the clock unit B will now be brought out with reference to the circuit diagram, Fig. 9.

For the purposes of this case, motor M, automatic ejector control relay I2I, and clutch magnet I22 are to be disabled.

For this purpose, switch IR is opened to break the circuit path through ejector control relay IZI to thereby disable the ejecting'mechanism. The contacts I24 which are closed bythe action of the ejector remain open and consequently clutch magnet I22 cannot be energized. The clutch magnet when energized causes opening of normally closed contacts I25 and closing of contacts I28) Since the clutch magnet circuit is now opened, the contacts I26 remain open and prevent making of the circuit through motor M. The punch unit is thus in condition for manual and clock controlled operation without interference by the automatic feeding and ejecting mechanism.

As an example, assume that employee 225 of department 15 presents his card to the pnnch operator at 9:07.

The operator inserts the card T in the punching section and pushes finger piece It!) to the right (as viewed in Fig. l) to locate the card carriage and the card in first column position. The operator then manually depresses the proper keys F8 for punching in succession the department and man number columns of the card. Depression of a key, as previously explained, closes contacts ll'il.

A. circuit is thereupon completed as follows:

From terminal EZ'I, through punch magnet HM, contacts Mil, normally closed contacts i25, and line 29 to terminal I36.

Energization of punch magnet I84 causes the key-selected punch pin l5 to perforate an index point position of the card column then under punch column. Following the punching of the hole, the escapement mechanism functions to feed the next card column under the punches.

After the department and man items have been punched in the workmans card T by manual operation of keys E6, the first oft e date columns reaches punching position. T e date is prepunched on a pattern card P in the same columns as those of card T which are to receive the date punching. The card P feeds with respect to sensing brushes i3I in synchronism with the feed of card T with respect to the punch pins "I5. When a date-punched column of the pattern card reaches brushes I3l, one of the latter senses the date perforation and makes contact with a common contact roll I32. A circuit is then com.- pleted, without manual intervention, through the punch magnet I04, as follows:

From terminal I21, through magnet 82 connected to the brush ISI sensing a perforation in the pattern card, the latter brush, contact roll I32, common return brush I35, contacts I35, line I31, contacts I25 and line I29, to terminal .138.

Energization of the magnet 82, selected by above circuit, operates the keys [5 to cause a punching operation.

The date columns are punched under pattern card control and the card T, as a result, is automatically fed to locate the first of the start columns in punching position.

As previously assumed, the card was presented to be punched at 9:07. Consequently, at this time, the hour selector brushes 58 have moved nine steps from the 12 o'clock position and tens order hour brush 58 is engaging a commutator contact 65 hooked up to a 0 line while units order hour brush 58 is engaging a contact 61,.

marked 9. i

In the minute section of the time selector, the brushes 58 have moved one step from a- 00 minute lines I33, I34, the

thus automatically position to a 06 minute position and consequently,

tens order minute brush is engaging a commutator contact 6| connected to a 0 line while the units order minute brush is engaging a commutator contact 83 marked 6.

The time is to be punched as tens of hours, unit hours, tens of minutes, and unit minutes. Accordingly, the first of the start columns is to be controlled by tens order contacts 61, the second by units order contacts 66, the third by tens order contacts 63, and the fourth by units order contacts 6.I.

When the first of the start columns of the card reaches the punch line, one brush Illa of the column selector is engaging a contact II2-I of the column commutator III which corresponds in order to the first of the start columns. Another brush IIOb is constantly wiping a common return contact bar I40. Connections are made from each contact point II2 to sockets I of a plugboard I42. On the same plugboard are alined plug sockets I43. Plug wires I44 provide interchangeable connections between sockets MI and 1-33 so that punching of the time may be selectively located in any desired group of card columns.

The pattern card P is unperforated in the columns corresponding to the time columns of card T. Therefore circuits cannot then be formed through the sensing brushes ISI of the pattern section.

With the time selector parts in positions as described, the arrival of the first start column of the card in punching position automatically establishes the following circuit:

From terminal I21, through lines I33, I24, magnet 620, one of the lines I46, tens order hour selector contact 66 (ninth from the right), brushes 66, common return element 66, sixth minute cut out contacts 4I (see also. F18. 3) normally closed contacts I41, line I46, normally closed contacts I4la, plug socket I43, plug wire I44, plug socket I4I, contact II2-I of the column selector, brushes IIOa and b, common return bar I40, closed contacts I46, switch I60 (closed for clock control selection), line I6I, contacts I36, line I31, contacts I26, and line I29 to terminal I30.

Magnet 820 is energized by above vcircuit and the punching mechanism operated as a consequence to perforate the position of the first start column.

At this point, the purpose of the sixth minute cut out contacts 4I may be made clear. Twentytooth disk 29 moves under control of cam 26 one step every sixth minute. When disk 29 moves from the 54th to 60th minute,its cam 42 causes the hour disk 46 to move one step through follower 46, shaft 21, lever 46, and pawl 41. During either of the transfer operations from cam 26 to disk 29 and from cam 43 to disk 40, itis. ,de-

sirable to delay punching in order to prevent an incorrect punch registration of the time. For this purpose, cam 26 opens sixth minute cut out contacts M at each sixth minute in the manner previously explained. Accordingly, the circuit through higher order selector contacts 65 cannot be made and none of punch controlling magnets 02 can be energized until contacts 4| close at the end of the 6th minute interval. Since the higher order or first column of the start or finish columns cannot be punched, the card and the column selector remains stationary, and punching in the other orders is also prevented.

With sixth minute cut out. contacts 4I closed,

the above described circuith effective to cause. punching in the first start column. The card feeder then moves one columnspace, causing column selector brush I lie to engage the column selector contact "2-2. As a result, a circuit is automatically established from terminal I2l through lines I22, I24, agnet 02-0, a lead I46, units hour selector c tact 61-.4, brush 60 (now engaging this contact), the other brush 60, bar 00, normally closed contacts I64, line I66, and through the plugboard connections to column selector contact II2-2. From this point on the circuit is completed'as previously described.

The above circuit energizes magnet 62-8 to cause a 9" hole to be punched in the second start column.

In a similar manner, circuits are successively completed through the tens order minute selector contacts 6i-0 and the units order minute selector contact 631 so that the third and fourth start columns of the card successively receive 0" and 7" perforations. The first finish card column is now in punching position and column selector brush IIIIa is engaging column selector contact lI25. This contact is wired to plug socket 143a to which is connected a skip control. The circuit for the skip control is automatically completed when the first finish card column reaches punching position, as follows:

From terminal I21, through lines I33, I34, magnet 62-X, line l6'I,line I56, normallyclosed contacts I69, socket So, the plug connections to column selector contact II2--5, and from then on as in the previous circuit.

Energization of magnet 62-X results from above circuit to cause an X hole to be punched in the first finish column and also to move the skip lifter II6 forward into a depression III of the skip bar H6. The skip lifter maintains this forward position while the rack 88 advances be.- cause of the X punching operation to the next column. As a result, skip bar II6 has advanced to the left (Fig. 2) and the lifter now engages a high portion of the skip bar, thereby releasing escapement pawl 90 to cause the card carriage to move to the left. The skip bar maintains the escapement pawl 60 released until the card carriage and card reach last column position, whereupon the operator may remove the card. (The contour of the upper edge of the skip bar in relation to the card columns is indicated in Fig. 2).

Summarizing the start time punching operation; the operator places the card in the punch machine and through thumb handle I00 moves the card feeder to first column position. The department and man number are then punched in both the hour and minute selectors then automatically cause punching of the start columns,

and this is followed by an automatic X punching and a skipping of the.finish columns.

when the workman finishes the job, he presents his card to the punch operator who, as before, places it in the machine and moves it to first column position.

The operator then depresses a special finish key-l6l (see Figs. 1 and 9) which closes the following circuit:

From terminal I21, through line I6I, relays I62, I63, I64, and I65, finish key contacts I60, and lines I66 and I26 to terminal I30.

Relay I62 shifts contact-carrying blade I61 to open X-punching contacts I69 and to close first column finish time contacts I66. Relay I62 also opens first column start time contacts la and closes x-punch contacts I60.

Relay I63 opens contacts I41 and I54 and closes contacts I10 and Ill.

The effect of. opening x-punch contacts I69 and closing X-punch contacts I" is to shift (5 the X-punching circuit from the first finish column to the first start column.

The effect of opening contacts Idla and closing contacts I68 is to transfer the tens order hour selector control from the first start to the first finish column.

The effect of opening contacts IE1 and- I54 and closing contacts I10 and I'll is to transfer the tens and units orders hour selector control from the first two start columns to the first two finish columns.-

Relay I65 functions similarly to relay I63 to transfer the minute selector control from the last two start to the last two finish columns.

Relay I65 closes shunt contacts I12 to by-pass finish lgey contacts I60 permittingv the operator to release the finish key immediately after its depression.

- The holding circuit for relays I62, i63, I64, and I65 then is completed from shunt contacts I12 through line I13, last-column cut-out contacts I14, and line I15 to terminal I30.

Contacts I14 are opened by the escapement rack 88 when the latter moves to last column the plug connections to column selector contact II2-I, brushes H011 and b, and from this point on the same as the previously described X punch circuit.

As a result, magnet 82X is energized to cause the skip lifter II6 to move forward. As seen from Fig. 2, the first start column is in line with a depression I I8 of the skip bar H5. When magnet 82-); is energized, it causes an X-punching operation to occur. This in turn results in feeding the card and escapement rack one column to the left. The upper edge of the slrip bar corresponding to the next three start columns is straight, thereby elevating the advanced lifter arm II6 to cause the card carriage to advance the card until the first finish column is in punching position. In this position, skip bar II5 has a depression II8, a previously explained, causing lifter arm II6 to drop and the escapement pawl 90 to stop automatic card feed.

The time is then successively punched in the finish columns under control of the hour selectors which now function to select the punches through the upper set of contactsI10 and Ill and the minute selectors which select the punches through-the upper set of contacts in the minute section.

The operator may now depress the usual release key R. (Fig. 1) to move the card to the last column position. when the escapement bar 88 reaches this position, a lug I80 thereon (Fig. 2) rocks a lever IN to open contacts I14, thus breaking the .holding circuit through relays I62, I63, I64. and I66.

In brief, the finish time proceeds as follows:

The operator inserts the card in the machine and then depresses finish key I to close contacts I60 and energize relays I62, I63, I64, and

punching operation I65. Relay I closes contacts I12 to establish a holding circuit for said relays, permitting the operator to release the finish key.

Relay I62 transfers the X-punching and skip control circuit from the first finish to the first start column so that when the first start column reaches punching position, an X-hole is punched and the start columns automatically feed past the punching position. Relays I63 and I64 transfer the time selector controls from the start to the finish columns. The latter are automatically time punched and the card feeder moved to the last column position to open contacts I14 and break the holding circuit through relays I62, etc.

The card is then removed by the operator.
