  • This machine may comprise a base I having ferred form of practicing the invention. slidabl-y mounted and guided therein a carriage
  • This preferred form consists of a set of con- 2 on which is a clip 3 adapted to carry a record trolling pins, one for each punching position of card 4, (Fig. 1).
  • Said carriage is biased to the 20- the card and a similar set of verifying pins one left by means of spring 5 attached to the base i coacting with each of the controlling pins.
  • At controlling pins and verifying pins are located the end of the carriage opposite said spring is on opposite sides of the cards.
  • a plurality of verifying pins 9 are provided, one verifying pins the latter are stopped in their pin for each index point position in a single coltravel when they encounter the card, their travel umn of the record card and spaced apart the in this case being considerably less than when same as said index point positions so that when 40 they push a controlling pin back through the acolumn is moved into proper position under said card.
  • the pins 9 are slidably mounted in the frame shown diagrammatically at 10, said pins being normally held upwardly away from the record card by means of springs I l.
  • a plurality of levers I2 pivoted at [3 on a horizontal beam member I4 abuts one end of the verifier pins at [5. The ends of said levers opposite their pivots abut a series of depressible keys l6.
  • These keys are slidably mounted in the frame of the machine diagrammatically indicated at I! and are held upwardly by springs l8.
  • Each key is provided with an indication corresponding to the indices on the record card and actuates when depressed its respective verifier pin cooperating with the index point position on the card corresponding to the key index.
  • the horizontal beam member [4 is fixed at each end to a link l9, (only one of which is shown for the sake of clearness) said links being pivoted at 20 to a boss 2
  • This beam is biased downward by the spring 22 and normally held in this position as shown in Fig. 1.
  • Below the levers l2 and running transversely of the machine is a press beam 23 rotatable about an axis 24 journalled in the frame of the machine diagrammatically shownat 25. Assume a record card is under the verifying pins, when a key 18 is depressed, its respective coacting lever I2 is moved clockwise about the pivot [3 moving downward the verifying pin 9 with which it coacts.
  • the other arm 33 of said bell crank terminates with a pawl 34 which becomes engaged with the escape sprocket 8 on the aforesaid movement of the bell crank.
  • the plunger 29 has at its lower end a fixed perpendicularly projecting arm 35 which cooperates with one arm 36 of a bell crank pivoted at 37 so that when plunger 29 and therefore arm 35 s depressed the arm 36 is moved counterclockwise about its pivot 31 disengaging a pawl 38 attached to said arm, from the escape sprocket 8.
  • said key and its respective verifying pin 9 are returned to normal position by means of the springs l8 and II respectively.
  • the press beam 23 is returned to its normal position by the plungers 28 and 29 which are biased upwardly by means of springs 39 and 40 attached to bell crank arms 3
  • the depression and release of said key l6 constitutes a complete cycle of the mechanism just described and permits the escape sprocket 8 to turn one tooth in a clockwise direction thus displacing the carriage 2 one step to the left sufficient to align the next successive column of the record card under the verifying pins inasmuch as the operation just described has verifled the fact that a perforation existed at the index point in question.
  • a casing 44 which houses a series of control pins 45 together with their operating mechanisms (Figs. 1, 2 and 3).
  • control pins 45 correspond with the number of verifying pins 9 and one control pin is located diametrically opposite each verifying pin so that when said control pin is in its upward position and said verifying pin is displaced downward the ends of said pins will abut each other.
  • the control pins 45 are slidably mounted in a frame 46 and are supported by levers 41 which pass through a slot formed in the lower part of the control pins said levers being free to slide back and forth in said slots.
  • At one end of the levers 41 is an enlarged portion containing therein an elongated hole 48 through which passes a shaft 49 common to all said levers.
  • a locking bar 51 slidably mounted in the frame is provided with a series of grooves 58 and raised portions 59.
  • a lever 60 is pivotally mounted by which said locking bar may be displaced to the right or left according to the function of the machine which will later be explained fully.
  • the grooves 58 align themselves with the levers 41 so as to permit said levers to enter said grooves when it is desired to raise the control pins 45.
  • the looking bar 51 is displaced to the left the raised portion 59 is brought opposite the levers being displaced upwardly and thus prevent the pins from being raised.
  • the push bar 52 having a lever 16 pivotally connected to one end is provided with a series of teeth 6
  • the verifying pin will be prevented from being depressed which will prevent the card from being fed in the manner already described. It will thus be seen that any error in punching the card will be indicated by the failure of the card carriage to feed.
  • a lever 60 one end of which is pivoted at 82, is pivotally attached at its opposite end to the locking bar 51. Said locking bar is biased to the left by the spring 83 attached to said lever.
  • the locking bar 51 is at the right hand limit of its travel and held in that position by the levers 41 in the grooves 58 previously explained (Fig. 2).
  • a latch member 84 Fixed to the arm 21 is a latch member 84 adapted to cooperate with a latch member 85 fixed at one end of a lever 86 pivoted at 81. Said lever is biased counterclockwise about its pivot by a spring 88. At the end of said lever is also a projecting lug 89 which overlaps the path of travel of the lever and is adapted to be moved by said lever in a clockwise direction.
  • is fixed to a rod 92 pivotally supported by bearings 93 in the frame of the machine. Said carriage lever extends at an oblique angle from the rod 92 so that the end of the carriage lever projects into the path of travel of the turned down portions of the carriages 94 and 95.
  • is so placed relative to the travel of the machine that when the carriage 2 is moved to its extreme left position the turned down portion 95 coacts with the card lever 9
  • these two last mentioned bars remain locked until the carriage has moved to the end of its travel at which time the turned down portion 94 of the carriage comes in contact with the carriage lever 9
  • These bars then remain unlocked until the carriage 2 again reaches the right hand limit of its travel.
  • a cross arm 96 At the end of the rod 92 opposite the carriage lever is fixed a cross arm 96.
  • the right end of said cross arm as viewed in Fig. 1 is formed up in an S-shaped member 91 the top left hand configuration of the S-shaped member is adapted to coact, when in its lowered position as shown in Fig. 1, with a similar, though reversely formed end 98 of a bell crank arm 99 so that the clockwise turning of the arm 96 causes the formed member 91 to cam the bell crank arm 99 pivoted at I00 in a clockwise direction about said pivot thus raising its other arm IOI out of the notch I02 in the locking bar 51 with which it is engaged when no card is under the verifying pins.
  • is biased down by the spring
  • a link I03 the upper end of which is formed into a loop through which extends the end of a lever I04 pivoted at I01.
  • Said lever is biased downward by means of a spring I05 and is adapted to engage a notch I06 to lock the restoring bar 65.
  • the lever I04 is held up by the bottom of the loop and out of engagement with the notch I05.
  • a record card 4 is placed in the card carriage 2, said carriage being now at its extreme left hand position.
  • the carriage is then moved manually to the right until the first card column to be verified, at the left end of the card is in alignment with the Verifying and control pins.
  • is turned in a clockwise direction thus unlocking the bars 51 and 65.
  • the unlocking of the bar 5'! permits the spring I! to move the push bar 52 to the right and by means of the projecting pieces to move'the locking bar 51 to the right against the tension of the spring 83 thus permitting the control pins 45 to be thrust upwards through whatever perforations exist in the column about to be verified.
  • a projection 12 on the restoring bar 65 moves the latch 4
  • the control pins 55 are again locked down by virtue of the portion 95 of the card carriage 2 coacting with the carriage lever 9
