Definitions

  • the present invention relates to statistical, calculating and like machines which are operated by mechanical records such as perforatedcards, and relates more particularly to a machine of the adding-printing tabulator type operated by perforated i'ecord cards.
  • Machines of this character as heretofore constructed provide means for analyzing or sensing the perforated cards and simultaneously with such sensing operation transfer and set into operation mechanism for record-- ing the sensed data in the machine. Also in such machines a designation means has been provided as a distinct and separate 1 entity from other parts or units of the machine whereby a change of designation fromv one group of cards. to another group results in the automatic stopping of the machine. Also in such machines it is necessary to provide supplemental cards, for effecting a clearing ofthe machine and for taking a total.
  • Some of the objects of the present inven; tion are to provide means to overcome the disadvantages of machines of the character mentioned; to provide an improved tabulating'machine wherein the speed of the machine is materially increased without introducing factors of error and uncertainty of action; to
  • cards automatically causes the machine to take a total; to provide for flexibility in the use of the designation control whereby any column of a card can be employed for"'designation control, or a single column can be used for designation control from any selected field of the card or a part of such field; to provide means for automatically clearing the carry members of the machine prior to taking the total; to provide means for causing the sensing o ration and the operation of transferring t e data sensed to take lace successively; to provide a machine 0 the resent character in which the ordinary functions of the machine or some of them are continuous during the total taking; to provide means for taking a total at a higher speed than the speed of the machine while normally functioning for analyzing operation; to provide means for automatically clearing the machine after a total has been taken and prior to the transfer of items or data from the first sensed card of a group having a change of designation; to provide means for analyzing a card during one-half of the stroke of the analyzing unit and to'transfer the analyzed data on the other half-of such stroke

  • the ends of the pin box 32 are attached respectively to two depending arms 33, (Figs. 2 and 3), each of which mounts a cam roller 34 to be held in contact with a cam face 35 of a cam groove 36 in a cam 37 fast to the shaft 31.
  • Springs 38 stretched respectively between the arms 33 and fixed points ensure the rollers 34 following the contour of the cam face 35.
  • the opposite face 40 of the cam groove 36 has a portion 41 concentric with the shaft 31 and opposite to the total portion 42 of the face 35 in order that the 5 pin box 32 may have a short rest period at the end of each stroke of the pin box as long as accumulation is taking place.
  • a latch 43 is provided and pivoted to a fixed part so that the action of a spring 44 normally holds it under a lug 45 fixed to one of the arms 33 or other convenient part.
  • a latch disengaging arm 46 is pivoted to the latch pivot 47 and is arranged to engage a pin 48 on the latch 43 when rocked by a connecting link 50 during total taking. Under ordinary accumulation the latch 43 is automatically released by a cam 49.
  • each sensing or analyzing operation is transferred to certain operating adjuncts of the machine and finally appears as a printed item on the record paper 51 which is automatically fed about a platen 52 arranged to receive the impact of the type 53 as each is brought to printing position and struck by a hammer 54.
  • the paper feed and hammer mechanism are actuated in proper timed relation by any suitable mechanisms known in the art and as they form no part of the present invention no illustration is made thereof.
  • Each sector 55 (Fig. 1), carries the desired number of type 53, which generally correspond in number to the number of data points or numbers in a record card column, and is controlled by its rack sector 56 which is connected thereto by a pin and slot connection 57.
  • All the pairs of type sectors and rack sectors are pivoted upon a common rod 58 and are thrown to operati e position, when permitted, by sector actuating springs 60 respectively stretched between a fixed part and the several restoring pawls 61 which are respectively pivoted at 62 to extension arms 63 of the respective type sectors and as the actuating means therefor are similar the description will be confined for the sake of clearness to one unit and its associated par-ts.
  • a re storing bar 64 (Figs. 1, 4, 5 and 7) is provided extending transversely of the sectors and having its ends anchored in the restoring frame plates 65.
  • This restoring frame is arranged to be rocked in proper timed relation by means of a cam plate 66 having its cam slot 67 receiving a roller 68 mounted on one end of the frame plates 65. Motion is transmitted to the plate 66 by means of a link 70 which receives its reciprocating motion from a crank arm 71 under the control of suitable operating mechanism well understood in this type of machine.
  • Each restoring pawl 61 terminates in a hook 72 which normally engages over the restoring bar 64 so that on the forward or setting movement of the sector 56 the spring 60 will causethe hook 72 to follow the movement of there storing bar 64 until the sector is stopped in its difl'erential positions and hence upon the return or restoring stroke of the bar 64 it will engage'and carry the, hook 72 and its pawl back to the initial position.
  • vertically movable stops 73 are arranged in a row beneath the rack sector 56 so that any one which is projected upwardly will be set in the path of movement of a stop lug 74 on the sector 56 and which is normally held by a zero stop 75 on the movable shutter 76.
  • This shutter 76 is arran ed to be moved out of the path of the lug 4 by the upward movement of any of the stops 73.
  • the stops 73 are mounted for sliding movement in a suitable cage 77 and are arranged to be respectively actuated by extension rods 7 8, (Fig. 2), the lower ends of which are guided through a plate 80 into relatively close'proximity to the pin box 32.
  • each pin 22 has a detent 81 pivoted to it and constrained by a spring 82 to swing to a position below the extension rod 78 which its pin 22 is to control.
  • the free ends of those detents 81 not set by an analyzing operation rest against the sides of the respective extension rods, but in the lower or analyzing position any pin 22 which has passed through a perforation in the card will bring its detent 81 out of en gagement with its extension rod 78, and
  • thef present invention eompreheiids broadly-the r automatic takingof a total on a change: of designation without employing a separate or independent designation mechanism infiu enced by the change in thedesignationcoh um'nof the card.
  • the rack sectors 56 themselves are utilized to sense a change in designation and cause the proper functioning of the total taking mechanism, and while in general several sectors act as designation control but one and its partswill be here described.
  • a sector 56 functions also as a dcsignationcontrol ineludes a stepped arcuate arm 91 connected at one end to the restoring pawl 61 and hav-- ing its teeth 92 arranged to be engaged by a selecting crankpawl 93, (Figs. 1 and 5), pivoted on a rod 94.
  • a selecting crankpawl 93 (Figs. 1 and 5)
  • crank pawl 93 is held out of engagement with the arm 91 by means ofa pin 95 located in a slot. 96 of a selecting slide 97 which is normally held by a pivoted .lateh 98 against the tension of a spring 100.
  • the latch 98 is pivoted about a rod 101 and when lifted releases the slide 97 to the action of the spring 100 so that the crank pawl 93 is free, unless otherwise restrained, to swing to engagement with the teeth 92 of the arm 91.
  • a holding bar 102 is interposed in the path of the free end of the crank pawl 93, and the latter is therefore released only at the proper time in the cycle of operations.
  • an inverted ratchet sector 103 in order to retain the sector 56 in its designation control position, an inverted ratchet sector 103, common to all the sectors 56. is provided, and has its ends supported by arms,
  • dwell 110 prevents rocking of the part 103 during that period of an ordinary analyzing cycle in which the stop pins 73 are depressed.
  • the holding bar 102 is in the nature of a bail bar supported by "arms 112, pivoted on shaft 94.
  • One of these arms 112 has rigid j therewith an arm 113 to which is pivoted a link 114, the lower portionof which is guided in its lengthwise movement by a slot in said link engaging the fixed pivot 115 of a lever .116;
  • This lever has aboncentric cain slot 117, into which projects a pin 118, fasten the link 114.
  • the end of the slot has an inclined extension 119, such thatwhen the lever 116 is rocked, this incline, acting on the-pin 118', will exerta. thrust on link'll i anctswing bar 102 forward out of contact with the dogs or pawls 93.
  • the lever 116 is swung, forthis purpose, by a' spring 120 stretched between said lever and the lowerend of link 114.
  • this lever 116v is locked in its inactive pos1- tion with the spring-120 stretched by means of a latch 122 pivoted to along link123,.said
  • link 123 has pin and slot connection with-an arm' 126 fast on the main operating rock shaft 300 of the head or upper part of the machine, this rock shaft being operated at suitable times by means including a lever 127 fast on its end.
  • the link 123 does not ordinarily follow it, and the pawl 122 has an inclined tail 125 adapted to be operated atsuch times by the arm 126 so as to release the pawl 122 when arm 126 swings forward with the'result that spring 120, acting on lever 116 and link 114, moves bar 102 to its inactive position.
  • a carry clear bar 130 is pivoted at 131 to a. fixed part and is connected to an operating arm 132 which is swung on its actuating stroke by a spring 133 and returned to inoperative position by the movement of the arm 126 in which position it is normally held by a pin 135 latched against a shoulder 136 formed on the carry clearing link 123.
  • This link 123 is held in latching position by a pawl 137 arranged to drop behind a lug 138 on the link 123 and its disengagement from the pawl 137 is effected by the downward movement of a pin 140 on the link 107.
  • the link 123 is free to move to the left, (as seen in Fig. 5) under the influence of a spring141 stretched between a pin 142 and the arm 126.
  • the movement of the link 123 also frees the arm 132 so that it swings the carry clearing bar 130 into engagement with the rear of those sectors which are in carry position.
  • the movement of the carry clearing bar 130 is here used to transmit motion by way of a crank 143 to the link which releases the pin box latches 43 (Fig. 2) in order that the pin box is free to be depressed by the springs 38 until its rollers 34 are in contact with the total taking portion 42 of the cam 37.
  • the timing and operation of the main opcrating arm 127 is such that whilst for addition and for listing of a group of items it runs at one speed but in the cycle in which a change is detected, a total printed, and the first item of a new group is added, itruns at twice its forme'r speed. That is to say normally it properly follows the analyzing cycle of the pin box but when a total taking operation is taking place the arm127 has two working strokes during one revolution of the main shaft 31.
  • the lower end of the operating arm 127 is connected to a crank disc 144 fast to a bevel gear 145 (Fig.
  • a ring segment 160 is arranged concentrically with the shaft 146 and projects from a face of a hub 161 on the shaft 146.
  • the opening 162 in the ring 160 is arranged and timed so that it receives a pin 163 projecting laterall from the end of the lever 154, and hence while the pin 163 is riding on the inner face of the segment 160, the pawl 152 will be held in engagement with the shoulder 151 of the sun member 150.
  • the shaft 146 receives its motion by means of a shaft 164 driven from the main shaft 31.
  • a link 166 extends downward- 1y from the wheel frame and joins one arm 167 of a bell crank, the other-arm 168 of which carries a pin 170 which is arranged to be locked in disengaged position of the accumulator wheels 165 by a latch 171. Movement is transmitted to the arm 167 by two springs 172 and 173 acting oppositely thereon, the spring 172 being stretched between a pm 174 on the arm 167 and a pin 175 on one arm 176 of an engaging lever, the other arm 177 of which carries a roller 178.
  • the spring 17 3 is stretched between the pin 174 and a pin 180 on a fixed part of the machine frame.
  • the spring 172 is stronger than the spring 173 in order to swing the accumulator wheels 165 into mesh with the rack sector 56 when the latch 171 is displaced the arm 177 having been rocked upwardly by the travel of a cam dwell 181 under the roller 178.
  • the parts are now held with the accumulator wheels 165 in engagement with the sectors 56 by a latch 182 hooking over a pin 183 on the arm 176.
  • the latch 182 is pivoted to a fixed part and has a trip finger 184 located in the path of movement of the pin 142 on the clearing link 123 whereby the engaging lever 176 is released on the forward stroke of the link 123.
  • This mode of disengagement functions only for total taking operations, and when the wheels 165 are controlled for accumulating, the latch 182 is released by.
  • a slotted arm 185 having pin connection with a. second finger 186 of the release latch 182.
  • a cam dwell 187 is formed 011 the cam 144 in offset relaspring 196 connected to a fixed pin 197.
  • each sector56 has a separate selecting latch 98, any sector, or more than one if necessary, can be selected for designation control purposes. Furthermore, by the present anrangement, any column of the card may be taken for designation control purposes and thrown into anysector selected for such control.
  • the common ratchet sector 103 is pivotally held at this time because it is coni nected to a link 107 and lever 108, which are held by the cam 110 against return movement at this particular time, which is when the stops 73 are down and going through a new sensing operation. It should here be noted that the common ratchet sector 103, if released from the cam 110, can move on its forward stroke through a small angle when the stop lug on the sector 56 whose restoring pawl is engaged with the COIIlll'lOIl ratchet sector 103 is not, retained by any stop such as when a designation stop which originally positioned the sector fails to be lifted following the sensing of a card exhibiting a change in designation.
  • the link 50 also causes t e pin box disengaging arm 46 to release the latch 43 from the pin box lug 45, so that the pin box falls to the position determined by the The movement of the carry-clear bar 130 v radius of the total portion 42 of the main cams 37.
  • the card which has caused the foregoin sequence of operations due to its change 0 designation has been ejected immediately on the first up stroke of the pin box to withdraw the selector pins 22 from the card, but the radius of this total portion 42 of the main cams is such that the selector pin pawls 81, which were not employed to raise stops 73 after the sensing of the card just ejected, are not brought sufficiently low to swing under the lower ends ofthe push rods 78.
  • this depression of th pin box and its interconnected frame which carries the rod 78 is sufficient to allow the lifted stops 73 to clear the heels of the sectors, so that the latter are free to swing on the total taking stroke.
  • These last functions are coincident in time with the engagement of the accumulator wheels 165, and are immediately followed by the forward swing of the sectors on the total taking stroke and the completion of this stroke is followed by the printing of the total and the disengagement of the accumulator wheels 165, because the pin 142 in the carry-clear bar link 123 engages the arm 184 and releases the latch 182 so that the spring 17 3 is now unopposed by the spring 172 and results in the withdrawal of the accumulator wheels.
  • This release of the selecting crank 93 allows the load of the spring 100 to again be applied to the arm 91 to cause the hook 105 to engage and be held by common ratchet sector 103 in the position determined by the new designation of the following group of cards, and the function of change detecting is again prepared.
  • the return stroke of the sectors 56 now begins and an accumulation is rolled in.
  • the slotted link 185 trips the release timing latch 182 to release the engaging lever 17 7 so that the spring 173 pulls down the arm 167 and disengages the accumulator wheels.
  • the pawl clearing rod 83 is caused'to function the engagement of the cam 90 with the ro ler 88 of the link 85, and this takes place substantially with the action of that portion of the lowering stroke which applies the analyzing pins 22, and thus removes those pawls 81, which hadlifted the rods 78 on the previous sensing operation, so that the retractor frame 202 coupled to the pin'box depresses all rods 7 8.
  • the completion of the lowering of the pin box is accompanied by the release I ,raised by the engaged pawls 81, and coincidentally the lever 154 is released because its pin 163 comes opposite to the opening 162 of the ring 160. This release of the lever 154.
