STIGKNEY, F HILLSIDE, NEW JERSEY, ASSIGNORTO ELLIOTT-FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF- DELAWARE oomnmnn rrrnwmrme Ann Annnve fihonmn Application filed August 11, 1922. Serial No. 581,051.

, This invention relates to adding machines, especially those which are combined with typew'ritlng machines, and is illustrated in connection with a machine of the Hanson type, or the well-known Underwood bookkeeping. machine.

In such machines, the typewriting mechanism is positioned above the adding mechanism. The digit-keys of the typewriting mechanism operate indexing devices of the adding mechanism, and, after the typing of a number is completed, a general operator is used for running the number into the dialwheels of the register. The indexing devices usually consist of a set of pins, and each digit-key is capable of setting a pin in any denomination. The denominations are selected by the typewriter-carriage, one after another, as the carriage progresses. The

the denomination-selecting mechanism.

The indexing pins are arranged in denominations and are mounted upon bars,

these denominational pin-bars being connected, by individual trains to a set of denomination jaoks, which are displaced one after another by means of a dog mounted upon the typewriter-carriage. Displacing' of the denominational pin-bars bring the pins thereon into position to be set by the digit-keys.

Usually in an Underwood machine having two or more registers, a complete system of denominational trains, including the jacks, is provided for each register. The registers are simultaneously operated, and the carriage must set jacks for all the registers simultaneously, thus putting considerable load on. the driving spring which propels the typewriter-carriage. One of the objects of this invention is to reduce this load, and to simplify the means whereby the carriage may set denominational pin-bars simultaneously for a plurality of registers.

To this end, each register is provided with its set of indexable computing bars, and connections are provided from a single set of jacks to set pin-bars in all of the registers simultaneously, each jack being arranged to operate a rock-shaft, these rock-shafts expresent improvements relate principally to tending transversely of the machine, and

each rock-shaft having arms thereon for displacing all of the pin-bars of the same denomination for the various registers.

In the preferred manner of practicing the invention, all of said pin-bars are normally out of reach of the jack trains or denomination-selecting mechanism, and the pinbars of each register are brought into coaction with the jack trains by means of an individual cam operable by the typewritercarriage, this cam being held depressed and the pin-bars accordingly functioning so long as the carriage is traversing the typing zone which is involved. While the carriage is out of said zone, such set of pin-bars is out of co-action with the jack trains.

Two or more sets of pin-bars may be brought simultaneously into use for co-operation with the jack trains by the use of individual cams for each set of pin-bars, so that computation may proceed in several registers simultaneously.

Said cams may be'carried upon blocks mounted on the carriage and the same blocks may carry the denominational selecting provided for each machine a plurality of blocks; each block having one, two or three cams. Thus, the mechanism and operation of setting the machine up for a avariety of work is greatly simplified. Saidfblocks may be formed with column stops,""and may be adjustable along a rack for arresting the carriage at the tabulating operation.

The provision of the transverse rock-shafts in the jack trains permits the placing of a register mechanism at the extreme right or the extremeleft portion of the machine, while the jacks remain at the middle of the machine, and this is an advantage whether or not additional registers are employed.

As the typewriter-carriage travels from right to left, the denominational selecting dog acts first upon the right-hand jack which must, therefore, be included in the right-hand wheel in the register is a units wheel, a transposition device is usually em-- parts and reduce cost, and also conduce to greater ease and certainty of operation. To this end, rods are connected at their lower ends to arms on the transverse rock-shafts of appropriate denominations and extend directly up to the denominational jacks, so

that a denominational train com rises only the jack, the rod, the rock-sha and the pin-bar.

Other features and advantages will hereinafter appear.

In the accompanying drawin Fi re 1 is a side elevation of? block adjusta le on the carriage and carrying a denomination-selecting dog, and also one ormore cams for controlling the selection of registers. This block also serves as a column stop for the tabulating' operation of the carrialge.

i re 2 is a sectional elevation taken at the line 22 of Figure 1. Figure 3 is a sectional elevation taken at about theline 3-3 of Figure 4 of an Underwood bookkeeping machine embodying the present improvements in one form.

Figure '4 is a rear elevation of the machine, showing .particularly the denomination-selecting and. register-selecting devices.

Figure 5 is a sectional lan of the rear portion of the machine, s owing the sets of indexing pin-bars and their relationship to the denominational jack trains,

The typewriting mechanism comprises alphabet type-keys and digit type-keys 11, all mounted on levers 12, wh1ch,'by means of bell-cranks 13, drive type-bars 14 up to strike against a platen 15, the latter mounted on a carriage 16 which runs along front-and rear guide-rails 17, .18, and is driven by a spring, not shown. For controlling its letter-feeding movements, the carriage'has a releasable rack 19, which meshes with a pinion 20, the latter connected to an escapement-wheel 21'. which is controlled by dogs 22 and 23. Vibrating movements of the dogs are effected by a curved universal bar 24, which is operated 'by the type-bars and has a frame portion 25 which engages directly with the dogrocker.'

Fromeach of the digit type-keys 11 depends a stem 27, which, when depressed, engages at its lower end an arm 28 on-a rock-shaft 29, there being one rock-shaft for each key 11. These rock-shafts 29 individually operate linkages 30, which are connected to arms 31 on the rock-shafts, and lower links or di 't bars 32, which are also connected, throng linkages 30, to the arms 31 and are depressed thereby for the purpose of depressing indexing pins 33, the latter being carried upon orwardl and rearwardly extending denominational computing elements or pin-bars 34. After a number is typed and its corresponding number pins are set, a general operator 35 is' operated, which may be ower driven, butis illustrated as operated by a handle 36 connected to a rock-shaft 37 the latterhaving sectors 38 meshing with idle pinions 39, and the latter meshing with racks 40 forming part of the general oplerator and having a transverse bar 41, whic as it moves forward, enga s the depressed pins 33, and, by means 0 racks 34" on the forward ends of the pin-bars, drives the register dials accordingl The pins 33 are all normally out of t e paths of the digit bars 32, but

each file ofpins may be brought into said paths b displacing forwardly the in-ba-r 34 which carries sald ins. One of t e features .of the present improvements relates to the manner of effecting such forward displacement of the pin-bars.

At its r'ear; end, each of the pin-bars 34 carries a pin 42, w hereby it may be set or displaced forwardly. These ins may be in the paths of arms 43 extending upwardly from a series of horizontal transverse rockshafts 44, so that, when any shaft is rocked, its arm 43 is rocked and lts corresponding pin-bar is displaced forwardly to bring its index pins 33 into the paths of the igit bars or links 32. The rock-shafts 44 are mounted on brackets 44" fixed to the machine frame, and are normally pulled by springs, 44 in a clockwise direction, as seen in Figure 3, to cause stops 44 on the shafts to engage with stops 44 on one of the brackets to thus hold said shafts in their normal positions. Each of the rock-shafts 44 is provided with a controlling arm 45 to a which is pivoted the lower end of a rod 46, the rods extending upwardly and being suitably ided in a plate 47 near their upper mi; To depress the rods 46, there is provided a set of acks 48 pivoted between their ends, the forward ends 49 of the 'acks each having a tooth 50, and these teet being engageable by a dog 51' upon the typewriter-carriage to lift the jacks one after another as the carriage is passing through the computing zone, that is, while typing is being done 1n the column for which computation is to be effected. These jacks ma be.

all substantially of the usual t pe, an as the front end of any jack is li ed, its rear end is depressed, thereby pressing down its rod 46 and rotating the connected rock-shaft 44. By means of these jack trains the pinbars 34 may be-properly advanced or displacedone set after another as the typewriter-carriage proceeds step by step through the computing zone.

Each of the transposing rock-shafts 44 ends out of reach, or range ,of the arms 43- carries an arm 43 to drive the corresponding pin-bar 34 in every register set, of which .three are illustrated, so that indexing pins may be set simultaneously in' all the regis-' ters by the use of only one set of jacks or jack trains.

In order to adapt the machine to operate in each single register or only two registers or all three registers at will when typing in any zone, means is provided for disconnecting any one or more sets of pin-bars 34 from the jack trains. Preferably, the connection and disconnection are effected automatically,

although the invention is not limited to an automatic operation. To this end, all of the sets of denominational bars may be held normally up with the pins 42 at their rear leg 60 of this lever pivotally supports at its up by said mlddle a yoke 61,"having a rectangular opening through which the pin-bars 34 of the middle register pass. In its normally raised position this slide 53 is efiiective, through the connections described, to hold the pm-bars 34 of the middle register in raised position, with their pins 42 above the path of movement of the arms 43 on the rock-shafts. The other slides 53 are pivoted at their lower ends to separate bell-crank levers 62, which levers are pivoted upon the shaft 57 between the legs of the lever 56%.

These bell-cranks are connected through the links 63 to operate bell-cranks 64. mounted on the machine frame. The respective bellcranks 64 pivotally support yokes 61 surrounding the pin-bars 34 of the outer registers for normally holding these bars out of the paths of movement of the arms 43. When all of the pin-bars 34 are thus held springs no computation can take place.

Upon the carriage will be provided three cams 65, one for each of the vertical slides 53 to depress it against the tensionof the springs 56, thereby lowering the connected yoke 61 and bringini the pin-bars 34 into position to co-act wit the jack trains while the carriage is in the computing zone. These cams ma all be provided upon a single control bloc 66 when all of the registers are to be effective simultaneously. Each block 66 carries a denomination-selecting dog151, previously mentioned. The block 66 as jaws 70, whereby it may be set 'to any desired columnar position upon the rack 71 provided upon the typewriter for the tabulating mechanism.

Upon the lower part of the block may be formed a column stop 72 to co-operate in the-- usual manner with the usual denominationstops 73 'of the tabulator.

' At the upper end of each of the slides 53 f I is mounted a cam 74, pivoted between its ends to the slide and having a beveled upper face extending above the upper end of the slide. A sprin 75, connected to the lower end of the cam %4-and to the slide, normally tends to force the lower end of the cam to its limit of movement in one direction, which limit is determined by engagement with a pin 76 on the slide. When the carria e is entering a computing zone, the beveled aces of the cams upon the control blocks 66 strike the beveled top faces of the cams 74, causing them and consequently the slides 53 to be thrust bodily downward. They are held down by the horizontal edges or dwells on the cams 65 until the carriage passes out of the computing zone. Upon the return of the carriage, the vertical end faces of the cams 65 strikeagainst the upper portions of the cams 7 4, which are swung about their pivots against the pressure of the springs 7 5 and are restored thereby to normal vertical positions after the cams have passed.

While, as thus described, all three registers may be in use simultaneously in the computing zone of a selected control block 66, the invention may be practiced by omitting any one or any two cams from the control block, so that, while the machine is.

being operated in the zone controlled by said block, any one or any two registers will be effective. It will thus be seen that there are several possible modes of operation of the three registers in any computing zone, because of the ran e of selection of control blocks afforde by the difierent cam arrangements, among these arrangements being, any one of the three cams individually, three possible combinations of two cams, and one combination of all three cams.

There may be provided upon the carriage a series of control blocks 66, as shown in Fi ure 4. Since the block inserted in any 0 the positions shown may control the registers in any one of seven different ways, according to the cam or cams upon it, the possible modes of operation of the entire machine will be seven raised to the nth power, where' n represents the number of control blocks actually employed. It will, therefore, be seen that the machine is adapted to be set up in any way desired for difficult classes of work by the use of a" simple, inexpensive device, readily ap lied and easily used. The dwell. portions 0 the other. While the pin-bars 34 are lengthened rearwardly, as illustrated at Figures '3- and 5, the invention is not limited to the use of extended bars nor to the specific arrangement of jack trains and connection-' efiectin trains and control blocks.

At Figure 5 it will be seen that the first denominational jack train includes the rearmost rock-shaft 44 whose arms drive the left-hand pin-bars 34, these being the bars of highest denomination. The next jack train'to be operated by the carriage as it proceeds fromright to left includes the next forward rock-shaft which operates the pin-bars of the nextto the highest denommation and so on, the last jack train including the front rock-shaft which operates the denominational. pin-bars of lowest denomination. Thus. the use of interposed transposition mechanism in the j ack trains is rendered unnecessary; and so far as this feature of the inventi n is concerned, it is noted that it is applicable to machines in which a separate set- 'ofj-acks is provided for each register, inasmuch as the use of the rock-shafts ermits the above-explained simplicity of construction and o eration whether or not the rock-shafts or one register are extended to operate the pinbars or one or more additional registers.

It will be understood, of course, that the invention is not limited in its application to machines having three registers, and that additional registers may be employed by increasing the number of cams on the control blocks and roviding suitable connecting mechanism tween the additional cams and the pin-bars of the registers which the are to control.

ariations maybe used within the scope of the invention, and portions of the improvements may be used without others.
