Definitions

  • FIGS 53 F
  • point perforations may e indicated by print- Ying upon a record strip, and, in addition thereto, such printing mechanisms are alsol employedto represent the result ofsome'couiputation, such as a total of a series of items. It frequently happens that it is desirable to identify the printed items or computations by printed words, abbreviations or the like,
  • the preferred means com rises a type carrying member providedv with) a. pluralityof groups offtype, one group for example, meral type, the second, letters of the alphabet and the last, if so desired, other letters of the alphabet.
  • the numeral group ⁇ of type are normally presented to the rinting point so that as the usual card per with the analyzing brushes differentially selected. If a perforation should register with an upper or the type will be controlling brush the corresponding group of alphabetical characters will be selected prior to the differential selection of the ty e as controlled bythe usual index oint perfporations. In this manner the car controlling columns may differentially control a number of type tomake up, for example, either a er, word, or abbreviation.
  • Fig. Y 1 is a transverse sectional view through the printing mechanism illustrating a single embodiment of the invention
  • Fig. 2 is a view similar to Fig. 1 illustrating the position of the parts for differentially selecting a type of the upper or alphabet group of type;
  • Fig. 3 is a view similar to Figs. 1 and 2 ⁇ illustrating the position of the parts for dif- Y ferentially selecting a type of the lower or second group of alphabet type;
  • Fig. 4 is a circuit diagram of the machine to which the present improvements are applied;
  • FIG. '5 is a fragmentary representation of a L part of a regular Hollerith card illustrated as punched for selecting either numerals or letters by means of the present invention.
  • drive shaft driven by the tabulating motor T. M. (Fig. 4) carries a box cam 27 the race of which reciprocates a bell crank lever 28 one endof which is attached by a link 29 to a reciprocating cross head 30.
  • a pair of levers 28 is provided to carry the cross head, the latter carrying a series of clutch pawls 31 adapted to engage with angular notches 32 formed in slidably mounted plates 33, one being provided for each printing order.
  • the spacing of notches 36 corresponds with the spacing of type bars 37 constituting, for example, numeral type bars of group A. It will be clear that as plate 33 rises differentially a rack portion 38 thereof will roll a pinion 39 counterclockwise over the rack teeth 41 of an impositively held plate 42. Pinion 39 is pivotally carried by the lower end of a slidably mounted plate 43 which carries at ⁇ its upper end the set of numeral type 37 constituting group A. lThe movement of plate 43 is, therefore, synchronous with the differential movement of plate 33 bringingl the desired type bar 37 in correspondence with a printing platen 44. The movement of plate 33 is also synchronous with the movement of perforated cards 45 (Fig.
  • the plate 33 may be stopped prior to the time that the cross head 30 completes its upward movement in which case pawl 31 merely rides out of engagement with the related notch 32 permitting an upward independent movement of the cross head 30. As the cross head is moved reversely downwardly the pawl 31 will re-enter the notch 32 to positively restore the plate 33 to its normal position.
  • Any suitable means may be provided for impelling the selected type against the platen 44 to perform the printing function, and may constitute hammers-46 each of which -impels an associated plunger 47 against the s electcd type.
  • the hammers are adapted to be struck by a bail 48 lhaving suitable connections to the operating parts of the machine. Since the hammer details form no part of the present invention they are not shown or described in detail herein and for details of a preferred construction, reference may be had to the application of C. D. Lake, Serial No. 541,347,
  • any of the numerals may be selected for printing, the particular one selected depending upon the position of the index point in the card column. It is desirable, at times, to print letters to form words, abbreviations or the like and to this end plate 43 carries two other sets of alphabet type, the alphabet group B being arranged above the numeral group A while the alphabet group C is arranged below the numeral group A.
  • the group of type B are selected for printing by an index omt in the R position (see Fig. 5) while tiie group of type C are selected for printing by an index point in the X position.
  • the type in the particular group selected are selected. for printing by th'e usual index points in the card column.
  • the preferred means employed to position plate 42 downwardly to select the alphabet type of group B comprises a cam slide 53 the lower cam surface of which coacts with a stud 54 carried by plate 42 so that as slide 53 moves to the left its coaction with stud 54 will cause plate 42 to.be cammed downwardly to the position shown in Fig. 2.
  • Slide 53 is provided with rack teeth 54 normally out of engagement but adapted to engage the teeth of a mutilated gear 55 which l carries a clutch pawl 56 associated with a sequently driving. slide 53 to the left by the gear 55 and against the tension of a restoring spring 63.
  • a straight edge or dwell 64 coacts with stud 54 during which time printing from the selected type is effected.
  • a similar device is provided for selecting the type bars constituting fthe lowermost or group C, which are also preferably alphabetical character bearing type.
  • the C group of type are selected by an index point appearing 1n the so-called X position, which is the eleventh index point position on the card.
  • the desired type in group C selected for printing is controlled in accordance with the usual index points appearing in the same column as the X index point.
  • a slide 73 coacting with stud 54 is provided for the purpose of elevating plate 42 to select group C type for operation, since it will be apparent that as plate 42 risesthe rack teeth 41 will cause pinion 39 to roll clockwise over the rack teeth 38 to elevate plate 43 bringing the type of groulp C in correspondence with the printing p aten 44, (see Fig.
  • a mutilated gear 7 5V (Fig. 1) whose teeth are adapted to subse uently mesh with rack teeth 76 of slide 73.
  • T e mutilated gear carries the usual clutch pawl 77 adapted to engage a notch 78 in the constantly rotated shaft 66, the effective action of the clutch pawl being established when a latching pawl 79 is operated bythe energization of magnet 80.
  • Magnet'SGis energized when an index point appears in the X position.
  • Slide 73 type of group C for 1s restored to normal by the usual spring 81' while a cam 82 (Fig.
  • a card column controlling numeral printing does not contain the perforations X or R, and has only theusual index point perforation for differentially selecting a particular numeral type bar of the group A. These perfor-'ations are sensed by the lower brushes 85.
  • the machine .circuits are, as usual, energized from a source of energy indicated at 86 connected to line Wires 88 and 89 by a double pole switch 87.
  • the upper brushes 90 which search the record cards for perforations at the X or R positions are energized through cam contacts 110 which close during the feeding of cards and open between successive card feeding cycles.
  • Brushes 90 are, of course, electrically connected in some suitable'manncr to sockets 111 connecting the pairs of magnets 62, 80, and in the present instance this connection is exemplified by the jumperconnections 112 thus electrically ,connecting a brush 90 and one of a pair of magnets 62 or 80, depending upon the perforation presented t0 the upper analyzing brush.
  • the commutator arrangement preferably provided for selectively controlling the energization of magnets 62 or 80 comprises a 'ver 28 is elevating plate 33.
  • magnet 62 is ⁇ momentarily energized to cause the clutching action between notch 58 and pawl 56 that a flat spring 122 (Fig. 1) is provided to restore latching pawl to-normal prior to the completion of the cardfeeding cycle in which the tripping action occurs.
  • a flat spring 122 Fig. 1
  • a relatively important phase of the invention is that the particular means provided for controlling group selection is active during -a different card cycle than that in which type selection occurs. This permits the upper brushes to be used for performing the a plurality of ⁇ groups of type,
