  • the well known Powers tabulator may be conceived as divided into three main components, viz: the
  • the base component contains the card hopper l, the card feeding and picking mechanism 2, the sensing mechanism 3, the totaling mechanism 4, some of the main drive devices, the reading retaining mechanism, the change of designation mechanism, and a suitableframework for supporting the mentioned mechanisms.
  • the framework is mounted on a leg supported bed plate (shown partially in Fig. 1).
  • the intermediate component consists of an open frame 6 for separating the base and computing components, and into which may be introduced any one of a variety of combinations of multiple translators.
  • the computing component contains the mechanism for summarizing and recording the items, or data, occurring as separate entries in preselected fields on the perforated cards.
  • the computing component is ordinarily constructed with several computing units. A typical example of a computing unit is illustrated in section in Fig. 2.
  • a main drive mechanism (Fig. 1), the total shafts 1 and 8, a paper supporting platen, or carriage, with its paper feeding mechanism,
  • the term forward herein means toward the front of the machine, which is towards the left Framework
  • the machine as a whole, is mounted on suitable legs attached to a main base plate (shown partially in Fig. 1), and on said base plate is a pair of boxlike frames 9, in which are housed the principal elements of the gearing, and the cams of the base component main driving mechanism.
  • Mounted on the base l2 of the computing component is a series of intermediate frames for supporting the mechanism of the computing units.
  • the said frames are tied together near the top with suitably located tie rods, which are used for the additional purpose of forming a pivot for the type carriers and actuators, and the universals connected therewith, which will be more fully described hereinafter.
  • frames 6 carry auxiliary frames l3 for supporting the main rotation shaft I4, and for supporting the elements of the timing mechanism for the rear totalizers.
  • Mounted near the forward upper ends of the frames 6 are the printing hammer assemblies, one for each computing unit.
  • Main drive All the universal elements of the tabulator are connected to the main drive mechanism, which consists generally of a series of cam bearing shafts permanently geared together.
  • a suitable source of power such as an electric
  • the end motor (not shown) is connected by a suitable form of clutch to the rotation shaft I (Fig. 1), on which is a series of worms for driving the base main shaft 52, the totaling mechanism main shaft Iii (see also Fig. 15), and intermediate shaft 5 for the computing component.
  • Said shaft ISO is connected through suitable gearing to the card feeding rolls, as has been set forth in detail in my patent No. 2,044,119, dated June 16, 1936.
  • the base mechanism main shaft 52 carries a pair of eccentrics for reciprocating the sensing mechanism 3,. (Figs. 1 and 9) and a suitable set of cams for operating other universal mechanisms, as is fully set forth in the cited patent.
  • the intermediate shaft 5 is geared: to the computing head rotation shaft ll (Fig. 1) which is provided with discs, which are in effect cranks, at each end, which are connected by pitmans (not shown) to arms fixed to the forward oscillating shaft 19 in the computing component.

  • a fan cam 20 resiliently connected to the said oscillating shaft 59 (as shown in Fig. 2).
  • each fan cam 20 Pivoted to each fan cam 20 is an irregular link 23, extending upwardly and rearwardly to one arm 23 of a frame 2!, one side of which appears at Fig. 2 so that the said frame and fan cam always move together.
  • is provided with a cam 2
  • the lower ends of the arms of each restoring frame 22 are connected. by a universal bar 22a for controlling the movements of the type carriers and actuating racks.
  • Extending forwardly from the rear of the link 23 is an adjustable link, whose forward end is pivoted to a crank fixed to the shaft 25. Also fast to the shaft 25 is a universal hammer restoring bail (not shown) for each computing unit.
  • a stop basket Near the base of the computing unit is a stop basket (Fig. 2) in which the stops 26-are located.
  • the stop basket is substantially of the form shown in the patent to Lasker No. 1,780,621, dated Nov. 4, 1930. Therefore, an abridged description will suflice.
  • Each stop is adapted to be elevated by an individual interpreter 21 to limit the movement of the totalizer actuators 28.
  • the sector 28 when a stop 26 is elevated, the sector 28 is limited in its forward movement, an extent determined by an odd digit, but, if the stop 28 is also elevated. the pressure of the actuating spring of the sector 28 can force the projected stop 26 forwardly an extra space, so that each stop 26 may be used meat of the actuators is governed by the defixed to the auxiliary subtotal shaft I24.
  • each type carrier 82 Associated with each type carrier 82 is the usual familiar printing hammer mechanism.
  • a second actuator I1I for totalizer 34' is connected to the first mentioned actuator 28 as is diagrammatically shown in Figs. 1 and 6.
  • All totalizer actuators 28 are provided with a spring and pin-in-slot connection with the corresponding type carrier 82 for effecting transfers or carrying of tens as is well known in the art.
  • One well'known form of transfer is partially illustrated in Fig. 2.
  • This mechanism comprises a seriesof flat members I13, pivoted at one end on a stationary rod I13a.
  • the opposite end of each of said members is formed into a hook I13b as indicated by dotted lines in Fig. 2.
  • the hooks lie between the totalizer wheels and the ends thereof serve as rear stops for sectors 28, the arrangement being such that a stud 28b on said sectors contacts with the end of said hook limiting the sectorfs movement toward the rear.
  • Each wheel in the totalizer, engaged by actuator 29, is provided with a tooth of substantially double thickness, the thicker section having a fiat face which engages once each revolution of a cam on the underside of the member I13 which stops the adjacent sector 28 ofthe next higher order, raising the nose of hook, permitting the sector 28 to move backward sufliciently to advance the totalizer wheel engaged thereby one tooth, thus registering one complete revolution of the wheel of the lower" order.
  • This mechanism is old and it is believed that a more detailed explanation of the same would be superfluous.
  • the forward end of the frame 33 is provided with a universal bar 33a for rocking spring urged bell cranks 3I, to which the 'zero stops 38 are connected, by a spring and pin-in-slot connection.- It, therefore, follows that, when cam I88 rocks arm I83, the shaft I24 and all of the frames 33 will be rocked to positively rock the bell crank 3
  • 'I'heusual forward totalizing wheels 34 are rotatably mounted on a shaft 34a carried by a cradle (not shown), which is rocked by a pair of integrally connected cam arms 38 embracing the said shaft.
  • This mechanism generally speaking, is old.
  • Pivoted to one of the arms 35 is a doubly notched pitman 38, which,
  • Each pitman 38 is connected by a slotted link I15 and spring I18 to a bell crank 39, loosely pivoted on the sub-total shaft 8, and the horizontal arm of each bell crank is resiliently urged upwardly by a suitable spring 39a so that the upper notch 38a of the pitman 38 normally engages the upper pin of the rocker 31.
  • the bell crank 39 is rocked its fullest extent, as it is by the shaft 8 when set for a sub-total the pitman 38 is drawn downwardly, but the lower notch 31b may not engage the lower pin because the totalizer is usually, (always after a series of additions), in engagement with its actuators, therefore, the -lower pin of the rocker supports the pitman in an abnormal position, as shown in Fig.
  • the distance between the pins on the rocker 31 is such that the pitman 38 may have an intermediate position and, hence, not be in operative engagement with either of the pins as shown in Fig. 5.
  • each pitman is provided, at its forward end (see Fig. 5) with a pin
  • Each forward totalizer has its individual timing and control mechanism, but all rear totalizers have the principal part of their timing mechanism in common.
  • the rotation shaft l4 (Figs. 1, 2 and 8) has fixed thereto a cam 40 (Fig. 6). Behind one of the crank discs 48a and cooperating with said cam 40 is a pair of spring connected bell cranks 4
