  • the present invention has for its object a printing device particularly adapted to be used in combination with statistical, calculating and tabulating machines utilizing perforated cards.
  • the printing device is such that a wheel carrying the types is given, at the time of the printing, a rolling movement v with respect tothe surface of the-paper, so that the instantanwus absolute velocity of the point of contact with the paper maybe zero.
  • the printing device can be made as described in my U. S. Patent application Ser. No. 540,166, filed May 26, 1931, and especially as disclosed in my U. S. patent application Ser. No.
  • the object of myinvention is to provide a device of that'character in which the type to be printed, the velocity of which in a direction parallel to the paper is zero, is given, at the very time of the printing, a sudden movement toward the surface of the paper, which produces the striking of said. type-against the paper.
  • this result is obtained by means of a guiding surface of suitable outline that acts'on the carriage so 4-) that the type carrying wheel may be given, besides its rolling movement on the paper, a sudden'movement toward the surface of the paper which produces the striking of the type to be printed against said paper.
  • Another object of my invention is to provide a printing device of that kind such that each of the type carrying wheels comprises a great number of signs, thirty or more for instance, which can be printed selectively according to the loca- 50 tion of the perforations that are provided inv the columns of the cards that pass through the tabulating machine.
  • each column twelve lines capable of receiving perforations, the individual. or single, perforations which correspond to certain signs according to the rank that they occupy in the columns of the cards are completed by other perforations, forming groups in said columns, 5 Y which correspond to other signs.
  • the first lines of the card thatls those with which the contact device first comes into register, are reserved, so that a perforation made in one of said lines corresponds in itself to no sign, while in the following lines, each perforation corresponds individually to a letteror a sign. Under these conditions, a. certain number of signs can be represented by a perforation made in one of the reserved lines combined with a second per- 15 foration made in one of the following-lines.
  • each column of the card comprises twelve lines
  • the two first lines will correspond to no letter and the alphabet will begin at the third line:
  • a perfog0 ration in this'third line represents letter A, a perforation in-the fourth line letter B, and so on as far as letter J, which'will be represented by a perforation in the twelfth line.
  • the letters following letter J will be represented by the combi- 25 nation, in the same column, of a perforation in the two reserved lines with a perforation in one of the other lines.
  • K will be represented by a perforation in the first line and a perforation in the third line, L by a perforation in the first 30 line and one in the fourth line, and so on.
  • Each printing device comprises, in combination with the type carrying wheel, a selecting device' actuated by the contact device or card examining device either electrically or mechanically and 35 which determines the printing of .the character or sign of the type carrying wheel that corresponds to the rank, or ranks, of the perforation, or perforations, met by the contact device in a given column. 40
  • this selecting operation is performed as follows:
  • Thetype corresponding to a character is located on the type carrying wheel 'a given number of positions away from the character that precedes it in a standard list of said characters.
  • each letter is located a given numberof positions away from the preceding letter of the alphabet. This given number of positions is advantageously equal to three.
  • a being the first letter on the wheel, 3 is the fourth letter, C is the seventh, J is the twenty eighth.
  • K is the third character, L
  • V is the fifth
  • W is the eighth
  • the selecting mechanism operated either electrically or mechanically from the contact device that is to say the mechanism that appliw, at the proper time, a toothed sector acting as arack against one of the toothed wheels of the set of wheels of the carriage and which therefore gives the carriage and the type carrying wheel their printing displacement, comprises a cam driven synchronously with the main shaft of the machine and a lever one of the ends of which is in contact with said cam.
  • the other end of said lever forms a stop of variable position adapted to coact with a pivoting toothed lever in mesh with the toothed sector that forms the rack.
  • the toothed sector acting as a 'rack is immediately caused, through the transmission existing between the contact device and the selecting device, to come into contact with one or the toothed wheels of the movable carriage.
  • the toothed lever in mesh with said sector is prevented from moving by the lever resting on the cam. Under these conditions, the toothed sector that acts 'as a cam is fixed on its axis and the carriage immediately brings the type carrying wheel into the printing position.
  • the contact organ comes into register with a perforation of the first lines of the card (reserved lines), which perfora-- tionhas only a meaning if combined with a second perforation of one of the following lines, the toothed sector is not immediately applied against one of the toothed wheels of the carriage,
  • Figs. 1 to 4 inclusive each show a vertical diagrammatic sectional. view of a printing device cording to my invention, these respective views showing the apparatus in different positions of its operation;
  • Fig. l shows the apparatus in the position of rest
  • Fig. 2 shows the apparatus in the position that corresponds to the printing of a character of the first series, corresponding-to a single perforation of the card (in the specific example shown in Fig. .2, letter- A);
  • Fig. 3 shows the apparatus in the position corresponding to the printing of a character or sign of the second series, corresponding to two perforations one' of which is located in the first line of the card (in the drawing character K);
  • Fig. 4 is'a'similar view corresponding to the printing of a character-or sign 'of the third series, corresponding to two perforations one of which is located on the second line of the card (in the example, character U);
  • Fig.5 is a partial end view of the machine
  • Fig. 6 is a plan view of a perforated card show- The whole of'the printing devices-one of which is shown on any of the views of Figs. 1 to 4 inclusive, is driven by a-common shaft I which turns synchronously with the tabulating machine so that the type carrying wheels 1 of all the;
  • printing devices may turn one revolution foreach perforated card passing through the contact device of the machine.
  • the tabulating-machine may be either wholly mechanical or electrical. In the example that has Just". been described in the drawings, it is electrical, so that every perforation of a card admitted through'the machine produces, at the time of its passing in front'of the contact device, an electric current which is conveyed to the electro magnet that controls 'the printing device corresponding to said contact device and brings said device into action.
  • the columns ofv a statistical cardgenerally comprise only twelve lines of perforations, as shown in Fig. 6.
  • a system of perforations an example of which 'is shown in Fig. 6. The two lines of the perfo divided into three series.
  • each character is representedv by a perforation in one of the lines'foliowing the third line inclusive (line 7) reckoning in the direction in which the contact device moves relatively to the card.
  • the machine which will be described with reference to Figs. 1 to 4 corresponds to a card containing only 30 characters, that is to say, perforated according to the system shown in the left hand side of Fig. 6.
