Definitions

  • This checking is at present done in two operations: squaring each stack of cards extracted from the delivery rack of the sorting machine and then lifting with the hands each stack of cards, holding it up to a light source and then sighting through the perforation to be checked to make sure that such perforation is in alignment through the entire stack of cards being checked.
  • the present invention solves the problem of making the checking of cards easier and faster by eliminating the effort involved in lifting and sighting the card stacks and doubling or even trebling the individual production because the checking is done simultaneously with the squaring of each stack of cards, an operation which is neces sary in any case.
  • these results, as well as others which will be described below, are obtained by using an instrument which comprises a flat base frame upon which is mounted a movable card holder, which can be fixed in any card column position, while two sighting devices, one of which carries a light source, are fixed to opposite sides of the base frame.
  • FIG. 1 is a perspective view of the instrument
  • FIG. 2 is a modified form of the instrument shown in FIG. 1;
  • FIG. 3 is a perspective view of the instrument illustrated in FIG. 1, with a stack of cards to be checked.
  • the instrument (FIGS. 1 and 3) carries a base table 5 of rectangular shape, to the sides of Which are attached two uprights 6 and 7 facing each other.
  • the former has a vertical slot 8 and the latter a similar slot 9, behind which is placed a light source 19 and a small reflector 11 of metal sheet, suitably curved to increase the reflecting effect.
  • a slidable angle table 13, 13' On base 5 is mounted a slidable angle table 13, 13', which can be moved lengthwise and is guided by ways 14. Parts 13 and 13' are respectively parallel and perpendicular to the base, and the latter carries on the outer face a turn button 15 fitted with a paWl which, engaging one of the notches 16 in the base of the instrument, locks angle table 13 in the desired position for the card column to be checked.
  • the angle table 1313' is eliminated and the pair of uprights 6 and 7 can slide along ways 18 in the longitudinal edges of the base plate, which is fitted with a square lip 5', uprights 6 3,134,839 Patented May 26, 1964 and 7 being attached to each other by a plate 19 which can freely slide underneath base table 5, the latter being mounted on four feet 26 which keep it spaced from the surface on which it is placed.
  • the operation of the instrument is the following:
  • the pawl of turn button 15 is engaged into one of the notches 16 in such a position as to make the perforation to be checked coincide with the alignment between upright slots 8 and 9. To this end, it will be useful to number notches 16 to match the numbers shown on the cards and indicating the ordinates of the perforations.
  • the stack 21 of the cards to be checked is then laid on table 13, which is slightly longer than the card, making sure that the front end of each card fits tightly against the edge 13'.
  • a mirror 20 shown in dotted lines in FIG. 1
  • the upright 6 it would be possible to use a mirror 20 (shown in dotted lines in FIG. 1), mounted at, for instance, 45 to the upright 6, so that the beam is deflected in a vertical direction.
  • An apparatus for checking perforations of punched cards comprising a base table, at least one upright located at one side of said base table and having an elongated vertical slot facing said base table, a source of light connected with said upright for projecting a beam of light through said slot across said base table, means located opposite said upright for receiving the projected beam of light, and card-engaging means connected with said base table, said upright and said card-engaging means being movable relatively to each other.
  • An apparatus for checking perforations of punched cards comprising a base table, at least one upright connected to one side of said base table and having an elongated vertical slot facing said base table, a source of light connected with said upright for projecting a beam of light through said slot across said base table, said base table having longitudinal guides, an angular card-supporting table movable upon said guides transversely to said upright, a mirror connected to said table and located 0pposite said upright for receiving the light beam projected through said slot, and means carried by said angular table for locking it in one of a plurality of positions pon said base table.
  • An apparatus for checking perforations of punched cards comprising a base table, an upright connected to one side of said base table and having an elongated vertical slot facing said base table, a source of light connected with said upright for projecting a beam of light through said slot across said base table, a reflector carried by said upright, another upright located opposite the first-mentioned upright and having a vertical slot alined with the first-mentioned slot, said base table having longitudinal guides, an angular card-supporting table movable upon said guides transversely to said uprights, said base table having a plurality of notches, and a pawl carried by said angular card-supporting table and adapted to engage any one of said notches for selectively locking said angular card-supporting table upon said base table.
  • An apparatus for checking perforations of punched cards comprising a base table, a plate extending under said base table and slidable longitudinally relatively to said base table, and two uprights carried by said plate and located opposite each other above said base table, said uprights having alined vertical slots, a source of light connected With one of said uprights, a reflector carried by the last-mentioned upright for reflecting light from said source, said source projecting light through the slots of the two uprights, said base table having a perpendicular end portion adapted to engage a stack of punched cards.
