Definitions

  • the present invention relates to tabulating machines and more particularly to tabulating machines of the type which are used to record information denoted by the perforations formed in a perforated indicia bearing card.
  • the object of the present invention is to provide a tabulating machine of the above-indicated type of such a simplified nature that it will place such machines within the reach of small business enterprises.
  • the tabulating machines for recording the information denoted by perforated cards have all been extremely complicated structures which were costly to manufacture and could generally be used profitably by enterprises having a tremendous amount of tabulating to be done.
  • the machine incorporating the present invention is relatively small, and the entire operations thereof are accomplished through mechanical movements performed upon the operation of a single operating member, which member may either be operated manually or by a small power motor.
  • Another object of the present invention is to provide a tabulating machine of the above-indicated type which is extremely flexible in that the information recorded by the perforations in any column on the card may be transferred to any column on the sheet upon which the information is to be recorded. Not only can the above be accomplished, but the adjustment whereby it can be accomplished can be carried out by the user of the machine, and thus the machine can be quickly and readily interchanged to obtain a desired recording.

  • the other arm of the lever 68 engages the lower end of a lever 88 which is pivoted intermediate of its ends on a bracket 88 and has its upper end in engagement with a cam 82 also mounted on the operating shaft I8.
  • the cam 82 is also provided with a flat 84 against which the upper end ofthe lever 88 rests when the carrier is in its lowermost position, whereas upon rotation of the cam 82, the upper end of lever 88 (see Fig. 3) is pivoted in a clockwise direction to actuate bell crank 86 and move the carrier 82 vertically.
  • the flat 84 on the cam 82 is offset angularly with reference to the flat" on the cam 68 so that the raising movement of the carrier does not start until the feed bar 48 has been moved inwardly through the extent of the carrier slot 52, whereupon the perforated card will be properly positioned on the carrier.
  • the feed finger 68 Upon raising the carrier, the feed finger 68 enters a carrier slot 86 extending vertically downwardly from the horizontal slot 52, and the feed bar 48 is held inwardly thereby until the carrier is again in lowermost or feed position.
  • the uncovered perforations therein will come into alignment with the lower ends of the sensing devices 88; there being provided a number of sensing devices corresponding to the number of columns on the perforated card l8.
  • sensing devices 88 there being provided a number of sensing devices corresponding to the number of columns on the perforated card l8.
  • this number may be expanded to perform the operations for any particular set of conditions.
  • each sensing device 88 is carried by and depends from a transversely arranged operator slide 88 provided on its opposite ends with rollers I88 which guide the slide in suitable vertical grooves I82 provided 'in guide members I84 secured to the side walls 28 and- 22 of the casing.
  • each sensing device lies in a plane forwardly of the carrier 82 and includes a connector rod depending from the slide 88 and extending through a suitable guide opening in a bracket I86 for properly guiding the rod and also forming a limit stop for engaging a pin I88 carried by the rod above the bracket.

  • the rod I20 which connects the slides designated as a and b, could be shifted to connect the slide a with the type bar carrier designated as-c.
  • the interconnecting rod, I20a could be shifted to connect the slide (1 with the slide b.
  • the feed bar 48 upon rotation of the shaft I by the operating handle I8, the feed bar 48 will initially operate to move a card into position on the carrier 32. When so positioned, the carrier will then be moved vertically until the projecting ends III of the sensing fingers align with the perforation in the card and carrier, whereupon the spring I I2 will pivot the projection into such perforation. Thereafter the sensing devices will be moved to cause actuation of the slides 88, which slides in turn, through the rods I20, will cause simultaneous actuation of the slides II6 to move the bars 82. Obviously the indicia on the type bar will be raised an amount corresponding to the movement of the platen following the engagement of an operator and thus properly align same for printing onto the master sheet.
