Definitions

  • This invention relates to punching or perforating machines and more particularly to machines of the type in which the punching may be controlled either manually or by a previously punched card.
  • a general object of the invention is to provide an improved and simplified machine of the type specified.
  • column cut-out bars have been provided with notches along one edge thereof located in accordance with the columns of the controlling record which it is desired to reproduce.
  • a socalled skip bar has also been customarily provided with notches along one edge thereof arranged in accordance with the columns of the blank card which it is desired to skip.
  • These column cutout bars and skip bars have a permanent configuration which is in accordance with the arrangement of data on the associated record cards and it has been necessary to provide a set of such bars for each different arrangement of data on the cards which may be used in the machine.
  • the main object of the present invention is to obviate the necessity for these mechanical bars and to provide a flexible electrically controlled device which may be pre-set to cause duplicating or spacing operations to occur automatically in any desired columns of the record cards.
  • a flexible plugging arrangement is provided whereby the duplicating and spacing positions in the machine may be readily altered to conform to any desired arrangement of data on the record cards.
  • a modification of the invention provides for a plurality of switches of which there is one provided for each column of the record card.
  • a switch associated with any column of the card when in one position may cause data to be duplicated or punched in that column; when in a second position, may cause the column to be automatically skipped; and when in a third position, may permit the manual punching of data in that column.
  • Fig. 1 represents a circuit diagram of the electric circuits of the punch including the card carrying mechanism in perspective outline.
  • Fig. 2 is a section of the essential operating mechanism of the punch.
  • Fig. 3 is a detail of the punch carriage escapement mechanism.
  • Fig. 4 is a detail of a punch magnet operating contact mechanism.
  • Fig. 5 is a sectional view of the analyzing mech-- anism for analyzing the master or pattern card.
  • Fig. 6 is a detail of a modified form' of switch controlled contact device. 6
  • the punching machine is generally of the form shown in the Lee and Phillips Patent No. 1,772,186, granted August 5, 1930 and the description thereof will be limited to the features essential to an understanding of the present invention.
  • punch selecting magnets I 0 are provided, there being one for eachindex point position of the record card. Energization of magnet ill will attract its armature to rock an arm II in a counterclockwise direction about its pivot l2, thus moving key l3 downwardly to rock a bell crank I4 which has connection with an interposer l5 which is suitably mounted for horizontal reciprocation. The forward end of interposer I5 is suitably guided between an operating bar l6 and the upper end of a punch l1.
  • ] in the interposer cooperates with a bail 2
  • contacts 23 complete a circuit through the punch magnet 24 causing it to attract its armature 25 and through linkage, generally designated 26, draw downwardly on the bar l6 to cause depression of the selected punch. 46 Depression of key I 3 may, of course, be effected independently of the. operation of the magnet in for the purpose of manually controlling punching operations.
  • the escapement mechanism comprises a holding pawl 30 pivoted at 3! to the frame of the machine and a stepping pawl 32 loosely pivoted on rod 28 and normally urged by a spring 33 into en gagement with the teeth 34 on the upper edge of the carriage rack 35.
  • 5 will lower pawl 38 into engagement with a tooth 34 to hold the rack 35 in position while punching is being effected.
  • This action at the same time raises pawl 32 out of engagement with teeth 34 and by virtue of its loose connection with rod 28 it will move slightly toward the right in readiness to intercept the next tooth 34 when the rod 28 is returned to its original position.
  • a pair of contacts 35 is provided which is so associated with the pawl 32 that the contacts are open when the pawl is in its raised position and closed when it is in engagement with a notch .or tooth 34.
  • a bell crank 31 pivoted at 38 to the frame of the machine carries a pin 39 underlying pawl 32. Energization of a magnet 45 will rock the bell crank in a clockwise direction whereby pin 39 will raise pawl 32 out of notch 34 to release the bar 35 from control of the escapement mechanism, thus permitting it to move rapidly toward the left with a continuous motion.
  • the rack 35 is suitably mounted for horizontal movement in the frame of the machine and may be manually moved toward the right to the position shown wherein a record card I9 is placed in position with the first column thereof in line with the punches
  • Gear teeth out on the underside of the rack cooperate with suitable gearing 4
  • Rack 35 is provided with extensions 43 and 44 between which a pattern or master card 45 is positioned and which is adapted to be moved back and forth with the rack.
  • An arm 45 carried by the rack 35 is provided for cooperation with the card I9 to move it column by column past the punches l1.
  • a contact roller 41 Positioned above the pattern card 45 is a contact roller 41 (see also Fig. 5)
  • a brush carrier 53 provided with electrically connected brushes 54 and 55, brush 54 being designed to cooperate with a common conducting strip 55 and the brushes 55 being designed to cooperate with individual con-' ducting blocks 51.
  • the strip 55 and blocks 51 are mounted in a block of insulating material 58 which is suitably secured to the frame of the machine.
  • One block 51 is provided for each card column of the record card and one of the brushes.
  • Each block 51 is electrically connected to a plugs 59 of the selected columns and a correthose columns in which it is desired to control the punching of data under control of the master card 45.
  • a special socket 54 is provided which, when connected to one of the sockets 59 by a suitable connection 55, will cause release of the card carriage for uninterrupted movement thereof toward the left.
  • plug connections 52 are made between the 20 spending number of sockets 53, and in those columns in which automatic spacing is desired, connections 50 are made between sockets 59 and a corresponding number'of sockets 5
  • switch 55 is closed to supply current to lines 51 5 and 58.
  • a plug connection 52 inserted in the first plug socket as shown, a circuit will immediately be completed from line 51, magnet 58, brush 59, contact roller 41, brush 10, to plug sockets 53, thence through connection 52 to the first 40 socket 59, brush 55, brush 54, strip 55, contact 35, wire 1
  • Magnet 50 is thereby energized to elevate the brushes 48 into contact with the pattern card 45, following which v the usual circuit or circuits will be completed 45 through the punch selecting magnets to duplicate the data perforated in column of the pattern card on the same column of the blank card l9.
  • These circuits may be traced from line 51, magnet 58, brush 59, common roller 41, perforations in 5 the pattern card, corresponding brushes 48, cable 12, punch selecting magnets l0, wire 13, to other side of line 58.
  • duplicating operation will 65 be repeated for as many columns as there are plug connections 52, contact 35 acting as a circuit breaker between columns.
  • magnet 40 will raise the pawl 32 out of engagement with the teeth 34 of rack 35 and the rack will there upon be urged rapidly toward the left under the influence of the spring barrel 42. This movement is sufilciently rapid to prevent the dropping of pawl -32 into engagement with teeth 34 until the rack 35 has reached the extremity of its movement toward the left.
  • the residual magnetism of magnet 40 will effect a delaying action upon forations bell crank 31,'-thus aifording assurance that the rack will reach the extremity of its movement toward the left before pawl 32 again drops into engagement therewith.
  • Fig. 6 is shown a modified form of setting arrangement in which each of the segments 51 is connected to the armof a switch 11 which, when set in the position indicated in the first orderv toward the right, connects the segment 51 to a socket 18.
  • switch I1 When switch I1 is moved to its central position as indicated in the second column from the right segment 51 is connected to a line 19 which corresponds to the common connection of the duplicating sockets 63.
  • switch 11 When the switch 11 is positioned as indicated by the third column from the right, connection is made to the segment 5! and a. line 80, which correspondsto the common connection 14, of the space sockets 5
  • the socket 18 may be connected to the socket 64 by the plug connection 65 for operation of the carriage release mechanism.
