Definitions

  • This invention relates to punching or perforating machines and more particularly :to machines of the type in which the punching may be controlled manually or by a previously punched card.
  • a previously punched card is placed in the reading or sensing section of the machine and the columns thereof successively read by electric contact devices.
  • a blank card is advanced column by-column across a row of punches which are actuated under control of the analyzing devices to perforate corresponding information in the blank card.
  • Fig. 1 represents a wiring diagram of the electric circuits of the punch, including the card carrying mechanism in perspective outline.
  • Figxla is a detail sectional view of certain circuit controlling devices.
  • Fig. 2 is a section of the essential operating mechanism of thepunch.
  • Fig. 3 is a detail of-a punch :magnet operating contact mechanism.
  • Fig. 4 is a fragment "of 'a record card which is to control the punching mechanism.
  • Fig. 5 is a fragment of a record card punched under control :of the vcard'in Fig. 4.
  • the punching mechanism is generally of the form shown in the Lee and Phillips Patent No. 1,772,186, .above'referred to, and also as shown in Patent No. 1,921,408, granted August 8, 1933 to' W. F. :Gutgesell. The description thereof will accordinglybe limited to those features essential to an understanding of the present invention.
  • punch selecting magnets H] are provided, there being one for each index point position of therecord card.
  • a .notch 20 in the interposer cooperates-with a bail 2
  • a bail 21 Disposed beneath the interposers I5 is a bail 21 which is carried by rod 28 upon one end of which is secured an arm 29 for operating the escapement mechanism.
  • Rocking of arm 29 (see Fig. 1) will lower holding pawl 30 into engagement with ratchet teeth 3
  • the rack 32 is suitably mounted for horizontal movement in the frame of the machine and may be manually moved toward the right to the position shown in Fig. 1, wherein a blank record card R2 is placed in position with the first column thereof in line with the row of punches l1.
  • Rack 32 is provided with extensions 35 and 36 between which the prepunched or controlling card RI is positioned and which is adapted to be moved to pass a row of analyzing brushes 31 as the card R2 moves by the punches I1. Brushes 31 cooperate with a contact roller 38 through the perforations in card RI.
  • the brushes are carried by a bar 39 which is normally in the position shown holding the brushes down out of engagement with the card RI.
  • the X brush 31 is connected for the purposes of the present invention through a wire 44 to the common contact blade of pairs of contacts C3 and C4.
  • switches 45, 46 and 41 are set in their dotted line positions and the X brush 31 will be connected through wire 44, contacts C3, switch 45, wire 48, X magnet I0, wire 49, contacts CI, switch 41 (in dotted line position) to wire 50 to which the other magnets II] are also connected.
  • a representative circuit may be traceable as follows, assuming a perforation present in the index point position of a column of card RI: from line through switch S, wire 5I, safety contacts 52, 53, wire 54, contact roller 38, perforation in the record card, 5 brush 31, cable 43, 5 magnet I0, wire-50, to switch S. Energization of the 5 magnet ID will advance the corresponding interposer and will also close the contacts 23, thereby energizing the punch magnet 24 to cause perforation of the card R2. Thus far, the operation of the punch is similar to that described in the patents referred to.
  • Card RI of Fig. 4 may have four separate fields each of four column capacity.
  • the numerical data in the index point position 0 to 9 is to be exactly duplicated in the record card R2 but the perforations in the X index point position are to be altered as follows:
  • the X punching in column 2 of card RI is to be omitted and X punching is to be added in column 8 of card R2, where there is no corresponding hole in card RI.
  • the perforation of column 11 of RI is to be omitted and the X perforation in column 13 is to be reproduced in the same column of the card R2.
  • the X perforation may indicate that the value perforated in the associated field is negative.
  • the first, third and fourth fields have negative amounts and the second field contains a positive amount.
  • the sign of these values has changed and it is desired to reproduce a card in which the new or changed signs will appear on the card.
  • the first and third fields are now positive, the second is negative, and the fourth has remained negative.
  • the data perforated in, let us say, the first field of card RI may represent a quantity of goods in stock and the same field of card R2 may represent the same quantity of goods taken out of stock.
  • the arm 36 has mounted thereon a brush carrier 55 provided with pairs of electrically connected brushes 56 and 51.
  • One of the brushes 56 traverses a common conducting strip 58 and the other brush traverses segments 59.
  • One of the brushes 51 traverses a common conducting strip 60 and a plurality of segments 6I.
  • a row of plug sockets 62 is provided from which plug connections 63 may be made to sockets 64 of the segments 59.
  • a second row of sockets 65 is provided from which similar plug connections 66 may be made to sockets 61 of the segments 6I.
  • a plug connection 63 is made between one of the sockets 62 and socket 64 associated with the second column.
  • a similar connection is made in the eighth position where the X perforation is to be added to card R2 and a third connection is made in the eleventh columnar position.
  • a connection 66 is made between sockets 65 and 61 associated with the thirteenth column and plugs 68 (see also Fig. 1a) are inserted from the rear of the panel 69 so that the segments 6I of the columns of this field are electrically connected to one another.
  • switches 45, 46, and 41 are thrown to their full line positions and with the cards in position to analyze and punch in the first column, this column will be reproduced as explained above and the carriage will escape to the second column in which the X punching occurs in card RI and a circuit will be immediately completed under control of the X perforation which is traceable from switch S, wire 5
  • the fourth field on the card RI may be one in which several other columns may have perforations which are to be reproduced and in such circumstances it is not desirable to make a separate plug connection 56 for each column whereby relay magnet 14 would be repeatedly energized and again deenergized between columns.
  • the connecting plugs 68 are therefore provided and inserted from the rear of the panel 69 so that one continuous electrical connection is provided between all the orders associated with this field and relay magnet I4 after energization during the analysis of the first column of the field will remain energized during the analysis of the remaining columns of the field and if such columns contain X perforations, they will be reproduced directly, in the same manner as explained for the first column of this field.
  • a perforated card reproducing machine means for analyzing a field of a record card in which a characteristic perforation may be present, means for perforating a field of another card under control of the field of the first card to reproduce all perforations other than the characteristic perforation, and automatically eifective upon analysis of the index point position of the characteristic perforation for suppressing the reproduction of a corresponding perforation if one is present in the analyzed card and for effecting a' characteristic perforation if there is none in said analyzed card.
  • means for analyzing a column of a card in which one or two index point positions may be perforated means for punching a column of another card, and means controlled by said analyzing means for causing said punching means to punch one hole in the second named card when there are two in the first and to punch two holes when only one is present in the first card.
  • a perforated card controlled machine means for analyzing a field of a record card having data representing perforations therein and in which the presence or absence of a perforation in a predetermined position indicates the arithmetical sign of the data, punching means controlled by said analyzing means to reproduce the analyzed data in another card and further means controlled by said analyzing means for changing the arithmetical sign indication of the data punched.
  • means for analyzing an index point position of a record means independent of said analyzing means for punching another position of a card column, a relay and a circuit controlled thereby for causing punching in said other position if no hole is present in the analyzed position and means controlled by said analyzing means for operating said relay to open said circuit for suppressing punching if a hole is present in the analyzed position.
  • means for analyzing an index point position of a record card a punch, controlling means, independent of said analyzing means for controlling said punch, means cooperating with said analyzing means for suppressing the operation of said punch controlling means if a hole is present in the analyzed position and for effecting an operation of said punch controlling means if no hole is present in the analyzed position.
  • means for analyzing a record column by column means for punching a second record column by column under control of said analyzing means, and set table means cooperating with said analyzing means for causing said punching means to perforate selected columns with an equal, greater or lesser number of perforations than are present in the corresponding analyzed column.
  • a punch for effecting a perforation in a corresponding index point position of 8.
