Definitions

  • This invention relates to printing mechanism and more particularly to printing mechanism of the record controlled type.
  • the invention relates particularly to mechanism for decoding and printing in true form alphabetic information which has been entered in perforated record cards in coded or condensed form.
  • alphabetic information such as names of salesmen, towns, classes of goods, and so on, are indicated by code numbers.
  • code numbers are indicated by code numbers.
  • These cards when passed through tabulating machines, are sensed and the coded information is printed on record sheets in code form. This is inconvenient where persons not familiar with the manner of coding attempt to read the printed record.
  • the present invention proposes to retain and increase the advantages of entering data on record cards in code form and to permit printing of the data in decoded or original form.
  • Fig. 1 is a view showing the essential elements of the printing mechanism of a tabulating machine.
  • Fig.2 is a detail in isometric of a print controlling commutator.
  • Fig. 3 is a detail of a further commutator.
  • Fig. 4 is a fragment of a record card.
  • Fig. 5 is a circuit diagram of the elements pertaining to the present invention.
  • Fig. 6 is a modiflcation showing anextension oi. the teachings of the invention.
  • a machine to which the present invention may be applied may be such as shown in PatentNo'. 1,926,883, granted September 12, 1933, to J. R. Peirce.
  • Fig. 4 is shown a fragment of a record card R in which a column ll may be set aside to rereceive perforations representing alphabetic information.
  • a perforation maybe made in any one of the twelve index point positions to represent any one of twelve names of persons, towns, etc.
  • the number of names which may be thus coded is limited to twelve and where a greater number of names is desired to be represented, perforations may be made in two or more positions in the same column.
  • the free end of arm 2 has link connection 25 with the type bar 21 which is suitably mounted for vertical reciprocation.
  • the bail 22 is rocked clockwise and arm 24 is urged in the same direction by spring 25, thus elevating the type bar and causing teeth 23 therein to move in succession past the toe of a pawl 29 normally held in the position shown by a latch 30.
  • Energization of printing magnet II as the type bar 21 moves upwardly will release pawl 29 so that its toe may engage one of the teeth 28 and interrupt further upward movement of the type bar.
  • the upper end of the bar carries the usual type elements 3i which move through printing position opposite platen 32. After all the type bars are positioned, printing hammers 33, provided for urging the selected type element 3
  • a commutator generally connection will be formed between brush 31, segment 36, ring 35, to the brush 38 which traverses the ring.
  • a further commutator which is disposed about shaft l2.
  • This commutator comprises a brush 39 carried by the shaft and adapted to cooperatesuccessively with segments 43 which are numbered 9, 8, 7, etc., and the timing is such that the segments are engaged as the correspondingly numbered index point positions of the record card are sensed by the analyzing brushes UB of Fig. 5.
  • any one of the magnets 43 may be energized in response to a perforation in a related index point position of the card column.
  • a pair of cam contacts close, completing the circuit from line 44', through contacts 50, relay contacts 43b (closed in the position corresponding to that of the card perforation previously sensed), a relay magnet 5
  • will close a pair of contacts 5
  • controls a group of contacts 5
  • b is connected to a plug socket 53 and the other blades are connected to wires 54 which terminate in plug sockets 55 from which plug connections 56 may be made to plug sockets 51 from which wires extend to the printing magnets II. From sockets i3, plug connections 53 may be made to groups of plug sockets 59 which are electrically connected to the brushes 31-which traverse the segments 36 on commutator 34.
  • the sockets 53 of each group are connected to sockets 53 corresponding to the letters of a selected word.
  • b are connected in Fig. 5 to the sockets 53 associated with the brushes which traverse the segments 36 corresponding to the letters in the word ALBANY.
  • the segments 35 contact with brushes 31 as the corresponding type elements approach printing position.
  • the segment 35 in the left hand column will be at its brush 31 and a circuit will be completed (if the first group of contacts 5
  • a similar circuit will be completed to energize another magnet H to interrupt the selected type bar in position to print L.
  • magnets II in other positions are energized to interrupt the corresponding type bars in the B, N, and Y positions to complete the printing of the word ALBANY.
  • the word to be printed under control of any group of contacts Si?) is determined by the manner in which sockets 53 are connected to sockets 59. Thus, for example, with connections such as made to the second group of contacts 5lb, the word TROY will be printed and if connections are made as to the third group of contacts 5lb, the word YORK will be printed.
  • occurs before the type bar begins its ascent and as it advances circuits are completed to each of the groups of printing magnets II associated with the contacts 5lb, the circuits being completed at differential times through the com.- mutator segments 35 which have been selected for operation and which correspond to the letters of the word to be printed.
  • the record card is being advanced past the usual lower analyzing brushes LB of the machine which brushes sense other perforations in the record card reiating to numerical data and control the entry of this information into suitable accumulating mechanism. While the card is passing the lower brushes, the next following card is moving past the upper brushes and a new setting is made on the relay magnets 43.
  • the "8" magnet 43 will be energized and held through its contacts 43a while the "9” magnet 5
  • -In Fig. 6 is shown a modification in which a greater number of magnets 5
  • the tracing of a specific example will serve to explain the operation of the system. Assuming a perforation in the "9 and "7 index point positions of the record card, the "9 and 7" relay magnets 43 will be energized in succession as these two positions are sensed by the brush U13 and their contacts 43a will provide holding circuits. Each of the magnets 43 controls the shifting of additional relay contacts 430 which are inter-connected as shown.
  • relay magnets 43 With relay magnets 43 in the "9 and 7 positions energized, upon the closing of cam contacts 5
  • magnet labelled 8-7- 6 will be energized when the "8", 7, and 6 positions of the column are perforated.
