Definitions

  • My invention relates to listing accounting machines and more particularly to means for controlling the printing and non-printing of numbers by the machine. Specifically stated the invention comprises means for preventing the printing of complementary numbers in a machine which subtracts by adding complements; or preventing the printing of all items so that the machine prints only totals; the mechanism being so designed that it can be thrown out of action if desired so that all numbers may be printed.
  • the present invention comprises a device settable to three positions in one of which, positive items will be printed but complements will not be printed, in another of which totals only will be printed and in another of which all items and totals will be printed.
  • This mechanism is especially useful in a card controlled tabulator and the invention is shown applied to such a machine where it controls the printing automatically according to the setting of the apparatus.
  • Fig. 1 is a front to rear, vertical section looking toward the left of a Powers tabulator having the invention applied thereto and Fig. 2 is a similar view on a larger scale of the head of the machine but looking toward the 7 right.
  • Fig. 3 is an'enlarged perspective view of the type hammer mechanism.
  • Fig. 4 is a similar view in the nature of a downward continuation of Fig. 3.
  • Fig. 5 is a diagram of the manually settable printing control key with explanatory legend.
  • the well known Powers tabulator which has been on the market for two decades comprises an upper or computing head section I including a plurality of computing units, an interpreter or connecting section 2 including any one of a set of interpreter boxes, and a lower or base section 3.
  • the head comprises the usual platen 4, type sectors 5 and spring and pin-in-slot connected adding sectors 6 both of which are pivoted on a cross shaft 1.
  • the type sectors are operated in one direction by the tension of individual springs i l and they are restored to normal position by a universal bail comprising a cross rod 12 and arms 53 pivoted on the shaft 1 and operated by the cam plate l4 connected by a link [5 with the usual fan shaped member l6 connected to move with the main operating rock shaft ll.
  • Each unit of the computing mechanism includes a set of accumulator wheels l8 (Fig. 2) mounted on a shaft 20 carried by pivoted arms 2 l
  • the accumulator wheels are moved into and out of mesh with the actuating racks E by means including a pair of connected cam rocking plates 23 mounted on a rock shaft 24 and having inclined cam slots which embrace the ends of the shaft 26.
  • Plates 23- are rocked by a link or pitman 25 having an upper notch 26 and a lower notch 2? for optional engagement with pins on the ends of rocking lever 28 which lever is operated through well known centralized wiper devices (not shown) by the fan it.
  • the pitman 25 is normally held in its upper adding position by a link 39 pivoted to an arm 3i on the total shaft 32 of the machine.
  • the connection between pitman 25 and arm 3i comprises the link 30, its pin-in-slot connection and the approximately parallel tension spring 34.
  • the construction is such that when the total shaft 32 is rocked counter-clockwise as shown in Fig. 2, the pitman 25 will be drawn to a lower position so that spring 34 will cause notch 2'! to engage the lower pin on arm 28 when the machine is set for taking a total.
  • the sectors 5 and 6 are controlled by stop mechanism'one form of which comprises a stop basket or frame 35 having therein a series of upwardly projecting stop pins 36 and a normally active zero stop shutter 31 cooperating with a lug 38 projecting downward from the actuator gear sector 6.
  • the zero stop shutter 31 comprises a plate extending along one side of the denominational series of significant digit stops 36, and said plate is pivoted at its lower edge and is pressed by a spring 40 into the path of the lug 38.
  • Means including a cam block are also provided controlled by the total shaft 32 for releasing all of the zero stops 3'!
  • Each of said wheels has formed thereon the usual transfer tooth 4
  • the hammer section of the machine comprises in each computing unit a set of spring urged hammers 44 pivoted on a collared spacing crossrod 45 and each is urged by its spring 46 to strike against that one of the sector carried types 4'! which is in printing position.
  • the hammers are normally held in their retracted or ineffective positions by a series of spring held latches 48 one for each hammer engaging a hook or projection 50 on the corresponding hammer 44.
  • the means for controlling the hammers includes the usual trip bars 52 each pivoted to one of the latches 48 and guided at its rear end in a comb plate 53.
  • Each of these trip bars rests at its rear end on a lever 54 pivoted on a collared spacing cross rod 55 and at its free end bearing against the edge of the type sector 5.
  • Each type sector has an incline or cam 56 which when the sector moves to bring the zero type to printing position swings the lever 54 and raises the rear end of the trip bar 52.
  • the construction is such that in the normal position of the parts as shown in the drawings the link 60 holds the bail 57 in the position shown in Fig. 2 where it engages fingers 63 of the hammers 44 and holds said hammers in their retracted positions.
  • the main shaft I! is rocked clockwise as seen in Fig. 2 during the operation of the machine and draws forward the link l5, the link 60 connected thereto rocks the bail 51 downwardly and forwardly until it strikes the trip bars 52 which may have been raised (if any) by the operation of the corresponding type sectors on levers 54.
  • trip bars are provided with the usual cross-over finger devices so that when one of them is raised it will raise all those to the right of it and thereby cause the printing of the necessary zeros.
  • bail 51 When the bail 51 reaches the extreme of its forward motion it will strike such of the trip bars 52 as have been elevated, release the latches 48,
  • trip bars 52 may be provided with optionally settable cross-overs so that only a predetermined number of trip bars to the right will be raised.
  • the connecting sE:tion*2 (Fig. 1) includes one of a set of changeable connection boxes or multiple translators 64 having in it the interpreter wires 65 which control the stops 36.
  • the base of the machine is here shown constructed substantially as described in the patent to W. W. Lasker No. 1,376,555 dated May 3, 1921.
  • the particular base illustrated contains the usual motor driven main cam shaft 86 (Fig. -1) which is connected in any desired manner (not shown) to a short rotary shaft 6! in the connecting sec- .the stack of pregrouped cards 14 from which said cards are fed, one by one, by the reciprocating picker i5 controlled by lever'76 which lever is oscil ated by a cam controlled spring pressed slide bar I1 and a cam 8
  • the picker feeds the cards to feed rollers 8
  • the card stop is mounted on the forward edge of the box 84. After the sensing operation the cards are fed by revolving rollers (not shown) into the. control of ejecting feed rolls 8! which transfer them to a suitable receptacle.
  • a cam for oscillating the bell crank 90 once for each rotation of said shaft.
  • which car- 'ries a stud 92 which is normally out of the path of a corresponding stud 89 on the bell crank 93 but will cooperate therewith under control of a total card.
  • Bell crank 93 and arm 94 are fixed totheir supporting shaft and the latter is connected by a long link 95 to an arm fast to the total shaft 32 so that the series of connected members are moved in unison when stud 92 cooperates with the stud 39 on bell crank 93.
  • a complemental item is represented by nines in the highest denominational orders.
  • the latch 48 of highest denominational order (Fig. 3) has a forwardly extending arm 5
  • interponent or trip bar 52 of highest order is in-' terposed into the path of the universal bail 51.
  • the latch 48 is rocked to release the corresponding hammer 44, but the said latch also, through link 58 and its connection to non-print bail 33, interposes the latter into the path of the hooks or projections 59 thus disabling the printing hammers When a complemental item occurs.
  • An arm of the non-print bail 33 has pivoted thereto a link 6
  • a spring pressed manipulative setting device H Pivoted at the upper end of the plate 18 is a spring pressed manipulative setting device H) which may have any one of three difierent positions which are determined by the engagement of any one of the notches identified as l, 2 and. 3 over the edge of a portion 8 of the case of the machine.
  • An arm 88 is attached to the total shaft 32 by means 01 a friction clamp shown conventionally as a grooved block attached to the arm 88 by means of screws with the total shaft 32 interposed.
  • the construction and arrangement is such that when the slot l is astride member 8, the plates 18 and 62 are rocked sufiiciently to draw the link 6
  • the arm 88 contacts with the pin 99 rigid with the link iii to rock the non-print bail to inefiective position so that totals will be printed.
  • plate 18 is held against motion by the member It] so that when arm 88 elevates link 8
  • the parts When the manipulative member 10 is in the position where the notch 2 is astride member 8, the parts are in the position shown in Figs. 3 and 4 so that all quantities such as positive items and totals which do not require the release of the highest order printing hammer will be printed. If, however, a negative item should be recorded on the accumulator wheels and the highest order printing hammer selected, the universal bail 51 will rock the non-print bail 33 into the path of the hammers 44 by the cooperation of members 52, 48, 5i and 58, as hereinbefore described. This operation is possible, regardless of the position of arm l0, due to the pin-in-slot connection between plate 62 and link 8
  • the bail 33 is moved toan ineflective position by the rotation of total shaft 32. This movement is efiected by virtue of link 6
  • Fig. 5 is a diagram of the manipulative device III which graphically indicates the character of the printing for .the different adjustments of said member I 0.
  • notch l is astride 8
  • totals only will be printed.
  • notch 2 is astride 8
  • positive items and totals will be printed, but complemental items will not be printed and when notch 3 is astride 8, all items irrespective of their complemental character and totals will be printed.
  • means for adjusting said type carriers according to the data on said cards means for printing a type of each type carrier, means for accumulating the data recorded by said cards, means for totaling and printing the accumulated data, and
  • means for printing a type totals means comprising a series of stop members under the control of a sensing mechanism for determining the positioning of said type carriers, impact means including aprinting hammer for printing an appropriate type from said type carrier, latch means for restraining the said impact means until the printing time is reached, printing hammer restoring means, auxiliary means for restraining the impact printing means,
