Y., A CORYORATIONDF DELAWARE COMBINED TYPEWRITING AND CARD PEREORATING MACHINE Original No. 1,680,813, dated August 14, 1928,8eria1 No. 103,220, filed April 20, 1828. Reissue-No. 17,634, dated April 1, 1930, Serial No. 335,728, filed January 28,1923. This application for reissue filed MQIGIIQ, 1931. Serial N0. 520,125;

-' denominationally and a key-controlled backspacing mechanism usable for correcting a wrong denominational positioning' of the a carriage.

Means for denominationally positioning a especially useful when the perforator by suitable coupling means is operated jointly with a typewriting machine in which denominational positioning of the typewriter-carriage is practiced fora counting work.

.Such joint operation is for the purpose of producing perforated record-cards corresponding to data simultaneously typed on a. work-sheet in. the typewriter. As is well known, the record-cards are subsequently ,used in many Ways for statistical analyses, reports, groupings, etc. A line of data written on the typewriter may include portions which need not be punched in the record- 23 card, and while such portions are being typed.

the perforator must be inactive.

Heretofore suspension and resumption of jointoperation were effected by pressing or releasing a foot pedal which opened or closed a coupling circuit by means of which the two machines were coupled for joint operation- By improper or inopportune use of this pedal mistakes are liable to occur. A

further object of-this invention, therefore,

"' is the provision of'means for automatically controlling suspension and resumption of oint operation of the two machines, and particularly to provlde such controlling means as shall be readily settable or adjustable a d adaptable to such machines in whicht e carriages are not mechanically coupled.

Another object of' the present invention is the provision of means adaptable to such machines in which the carriages are not mechanically coupled, whereby "thestarting of the usual power-driven means for return of the typewriter-carriage automatically causes a. machine cycle of the card-perforatorto be initiated. During such a cycle the card is punched according to the data written on the typewriter. Toward the end of the cycle after the punching is completed'the perforator-carriage is also returned.

The automatic cycle-initiating means are so devised as to be operable irrespective of whether the. typewriter-carriage-return movement is initiated automatically, by the movement of the typewriter-carriage as it reaches the end of a line or manually by pressing the usual carrlage-return-key. Ianually controllable means are provided to make said automatic cycle-initiating means inoperative at will. Heretofore, in combined typewriting and perforating machines it was necessary to operate two keys at the end of every typewritten line. One key was operated to return the typewriter-carriage and another key was operated to initiate a machine cycleof the card-perforating machine. By the aforesaid means of the present invention, both functions may be accomplished by depressing only thecarriage-return-key, or, if the carriage-return movement is automatically initiated at the endof a typewritten line, no key need be depressed.

The invention is herein illustrated as applied to a combined typewriting and cardperforating machine embodying the wel known Underwood-Hanson bookkeeping machine and the Powers key-punch. The Powers key-punch, hereinafter called the cardperforator, is substantially of the type shown in the patent to V. W. Lasker, No. 1,287,706, dated December 17, 1918. The Underwood-Hanson bookkeeping machine, hereinafter called the typewriter, is substantially of the type shown in the patent to Frederick A. Hart, No. 1,27 0,411, dated June tional tabulating mechanism controlled by applicationof Alfred G. F. Kurowski, Se-

rial No. 48,723. filed August T. 1925 (now patent No. 1,683,97 9, dated September 11,1928), the operation of the typewriter-keys to print also actuatesthe punch-selecting mechanism,

so that punches for subsequently punching holes corresponding to the characters typed are selected. This selection is effected, as

Y each key is struck, by depressing and locking a pin over the punch or punches corresponding to said key. The card at the proper time is raised and those punches which have .not been selected rise with the card. The selected vpunches, held down by the locked pins, penetrate and punch therard by cooperating with a die-plate underneath the card. said die-plate having a hole for each punch.-

The card is raised and presented against the punches by means of a frame which includes the die-plate. This frame is raised and loweredduring a machine cycle of the perforator, which is initiated after the punches have been selected by operation of the typewriter-keys. Toward the end of this cycle'the punched card is ejected from said frame and replaced by a blank card. In the operation of the punch-selecting mechanism, the pcrforator-carriage carrying a row of twelve'pin-setting plungers actuated by the aforesaid electromagnets traverses the field of settable pins,.of which there is, as stated, one over each punch. There are forty-five columns of twelve punches each in the pcrforator shown herein. The perforator-carriage' moves in steps from column to column. At each step a punch or punches may be selected. It will be understood that operation of a type-writer-key may cause two punches to be selected if the corresponding character is designated by two holes in the same column of the card.

Since the punches are caused to be-selected by operation of the typewriter-keys, it follows that theyperforator-carri age tra-vel's step. by step in unison with the typewritercarriage, on account of the simultaneous actuation of their respective escapement mechanisms.

Heretofore, in combined typewriting, and

card-perforating machines in which the respective carriages are not mechanically cou-' led, no means have-been rovided for cf ecting denominational tabu ation of the perforator-carriage corelatively with denominationaltabulation of the typewriter-carriage.

In this invention, novel mechanism 15 disv.closed for causing a remote controlled perforator-carriage to move automatically at one step a distance greaterthan a unit feed ol the perforator-carriage, 0 t P a Punch tions on the card) may be called" by any names, that is, not only by the decimal names, units, tens, hundreds, ctc., but, for example,

by the names 1, 2, 3, ctc., or the names a,

b, 0, etc., or. in fact, by any denominational names that are assigned to them in a predetermined system.

4 Such means are provided in the present invention, which, in its preferred form, uses the mechanism usually )rovided in the illustrated card-perforator or efl'ecting so-called column tabulation. Said means, as a supplement to this mechanism, consist of novel well as for the typewriter-carriage, it is possible to tabulate both carriages to the same devices means of which denominational denomination in corresponding zones. It is also feasible, inasmuch as each of the car,- riages moves by a'ndunder the control of its 'own spring-motor and escapement-mechanism, that the carriages may be 'corelatively positioned or tabulated in corresponding zones of dissentaneous extents. For example, a card-zone for which the perforator carriage is tabulated may include only four denominational columns, while the corree sponding typewriter-worksheet-zone may have sa eight columns, the number of typewriter-.one-columns usually exceeding the number of columns in the corresponding card-zone inorder to provide for footing up a total of all the items in the typewriterzone. Furthermore, the corresponding zones on the typewriter-worksheetand the card may be. in .dissentaneous locations. For example, two'zones on the work-sheet for which there are corresponding zones on the card may be separated by one or more inter-' mediate zones for which there are nocorresponding zones on the card. While the typewriter is being operated for the intermediate; zones, the perfor ator-carriage may be caused; to -remain idle and stationary by means hereinafter explained. Then, when the work-sheet-zone for which thereis a cor,-

responding zone on the card is reached, operation of the denominational tabulating mechanisms will cause their respective carlated are in dissentaneous locations, the locations being dissentaneous in respect to the number of zones through'which each carriage has moved.

The usual column-tabulating mechanism of the card-perforator includes a key-controlled electromagnet, which, through the usual means, operatesa'nd sets a lever to release the carriage from the control of its escapement mechanism. The escapemen't mechanism, including an escapement-wheel and pallets, is mounted with said lever on the perforator-carriage. In effecting this release, the operation and setting of the lever disengage the holding pallet from the escapement-Wheel. A latch on the end of the lever is caught andheld'by suitable means when the lever is set, thereby sustaining the lever'in its set position. In the ensuing tabulating movement ofthe perforator-carriage,

' the latch, moving with'the carriage, encoun- 'ters a stationary but settable counter-stop and is tripped thereby. The holding pallet thereupon re-engages' the escapement-wheel, thereby arresting the carriage and stopping the tabulatin g movement thereof.

To denominationally position the carriage in the column predetermined by the position of the counter-stop, afseries of denominational stops, one for every denominational tabulating key on the typewriter, is provided. The denominational stops are selectively movable for interception .by the counterstops, and are supported in a structure on the perforator carriage. Said structure is mounted so that it' mov'eslongitudinal y and relatively of. said-carriage when a denominational stop is intercepted by a counter-stop. A tappet on said structure, as it thus moves, strikes and trips the aforesaid latch..

The counter-stop, which is usually one of a plurality of such stops, is settable along the usual stationary member which, however,

is shifted from its regular position in order that the tapnet presenting structure supporting the denominational stops may be interposed between said counter-stops andthc aforesaid latch.

Means controlled by keys, which{ in the illustrated form of "the invention. are the denominational tabulating keys of the type writer, are provided to select and move a denominat onal stop orresponding to the operated key. Suitable circuit-closing devices underlying the tabulating keys are provided and are actuable by said keys to close electric circuits, by means of which'electro- .ment of the perforator. not move with thecarriage but are stationary I magnets are energized to operate the denominational stop-selecting means. The operation of any tabulatmg key also actuates a supplemetary circuit-closing device, which is connected to the usual universal bar operated by the typewriter denominational stops, and is therefore common to all keys. This supplmentary circuit-closing device,

for reasons tobe explained later, is, by'suitable means, closed during the first and greater part of the tabulating' key-stroke, but,is

' open at the end of said stroke. Upon operation of any tabulating key said supplementary device closes a circuit toe'nergize the electromagnet which releases the perforator-' carriage fora tabulating movement, which, as stated, is terminated by means of the denominational" stop selected by operation of said key. 1

An electromagnet may be provided for each stop to actuate means to select said stop. Like the electromagnets for the pin-setting plungers, these e;ectromagnets are solenoids gregate that tent s to impede the free move- The magnets do relatively thereto.

' In the preferred form of the present invention, means for selecting a denominational stop are provided whereby the number of operating magnets and related pushwires is substantially less than the number i of denominational stops. 'The typewriter herein illustrated has 'nine tabul ating keys, and nine corresponding denominational. stops are provided on the card-perforators carriage. These stops are in the form of tabs upstanding from arms suitably spaced in parallel array and pivotallysupported in the previously-mentioned structure, so that the edges of the arms of said stops over-- lie. a number of stop-selectors alsosupported in said structureand slidable transversely of and under said edges. A spring on the end of .each armurges rotation of the stops about a common fulcrum shaft, so that the stops tendto move into a position for interception by a counter-stop;

The stop-selectors have'formations which normally oppose and prevent such rotation.

These formations on each selector are so coordinated to the formations on the other selectors as to leave an opening for the arm of a denominational stop, whichmay then rotate'only if a corresponding arrangement ofthe relative positions of the selectors is effected. To effect this arrangement the selectors are relatively moved.

ing their normalpositions, if for each arrangement one or two selectors areshlfted from normal. Thus only four solenoids, one

for each stop-selector, need be provided to effect the selection ofany one of'ten'de- I nominational stops. A group of five selectors affords fifteen different combinations if no more than two selectors are shifted. Each .selector is caused to bemoved, by energizing a corresponding solenoid, to the plunger of which it is connected by means of-one of the aforesaid push-wires.

The arms of the denominational stops being spring-pressedand normally bearing on the opposing formations of the stop-selectors,-

means are provided to hold said arms clear of the stop-selectors while they are beingshifted. Said arm-holding means are operatively connected to the usual universal member on the perforator-carriage and actuable either movement.

are operated by a magnet, which, as already forator-carriage.

-by the typewriter-key-controlled punch-- selecting means or by the means that release the perforator-carrlage for a tabulatlng Said carriage-releas ng means explained,- is energized during onlya part of the tabulating key-stroke. At the end of said stroke, the arm-holding means have re- "assumed their normal positions, allowing the arm of the selected denominational stop to fall into the opening presented by the stopselectors that were caused to be shifted during'said stroke. The arm of the selected stop remains in this opening until either a printingkey or another tabulating key is operated. Operation of a printing key causes the arms of all the denominational stops to be held clear of the stop-selectors,which,beingspring pressed, reassume their normal positions.

. Means for: back-spacing the perforatorcarriage include a longitudinal member having teeth or-notches spaced according to the Said -lon-' steps of the ,perforator-carriage. gitudinal member is mounted so that it may first be moved to engage one of its tooth or notch formations with a suitable, projection on the perforator-earriage, and then further moved to effect a back-spacing step of the per- The back spacing movement of the longitudinal member is limited by a. stop, which, in conjunction with proper formation of the teeth or notches on said member, substantially prevents overthrow of the pe'rforator-carriage in back-spacing.

To impart'the aforesaid movements to the longitudinal member, means operated by an electromagnet are provided. This electromagnet by'means of a suitable circuit-closing device is caused to be energized by operation of the usual back-space key of the typewriter. Full depression of said back-space key causes a slight excess of movement inthe resulting back-spacing step of the type writer-carriage, and it is that part of the backspace key stroke, incidental to said excess movement, during which the circuit-closmg device for the perforator-carriage backspacing solenoid is operated. Thus the typewriter-carriage has completed its back-spacing step before a back-spacing movement is imparted to the perforator-carriage. This is a necessary condition if means controlled by the position and movements of the typewriter-carriage are used'to automatically 511spend and resume joint operation ofthe two machines.

In the present invention the coupling means between the typewriter and the cardperforator include a main coupling circuit. For suspending and resuming joint operation between the typewriter and card-perforator,

a clrcuit-opening device normally closed 1s provided and placed near the type-writer- (Carriage, and is connected in the main coupling circuit. To cause said device to be open while the typewriter-carriage is passing through predetermined zones in which joint operation is suspended, there is provided on the typewriter-carriage a member having notches into which different stops may be set in the same manner as tabulating stops are set. These stops have edges or surfaces which, as the typewriter-carriage moves into and through said zones, open and hold open the circuit-opening device. The extent of said surfaces which hold the circuit-opening device open depends on the extent of the zone in which joint operation is suspended. One of.

said surfaces becomes an edge if suspension and resumption of joint operation occur in two consecutive steps of the typewriter-can riage.

Included in the coupling circuit is the solenoid that operates the back-spacing means for the perforator-earriage. When the main coupling circuit is broken during suspension of joint operation, the perforator-carriage will not be back-spaced when the typewritercarriage is back-spaced. At the end of the step in which ,the typewriter-carriage passes from a zone in which joint operation was suspended, the main coupling circuit is again closed. If at this stage it is necessary to backspace the typewriter-carriage, the main circuit must be broken before, the back-spacing solenoid is energized, or else both carsaid stage of the riages will be back-spaced. Therefore, as explained, the typewriter-carriage is backspaced and the main circuit is broken before.

the completion of the back-space key-stroke, and, since it is during the completion of said stroke thatthe back-space solenoid is ordinarily energized, the perforator-carriage at typewriter-carriage will not be back-spaced.

The typewriter and card-perforator may be used under circumstances requiring a frequent change of the setting of the aforesaid stops, whereby joint operation-is suspended, and a large variety in the kind of work done may require a large assortment of stops, owing to the different lengths of actuating surfaces required. There is therefore also shown herein means whereby uniform stops may be used. Such uniform stops are also settable on the typewriter-carriage, and,

I when said carriage moves into and out of a zone of suspended o1nt operat1on,-are.eflective to rotate a pinion provided for this purpose. A commutator switchspanning a pair of brush-like contacts bearing thereon is connected to and actuated by said pinion. Said pinion has a limited number of teeth, so that a stop may, in one letter-feeding step of the typewriter-carriage, engage an rotate said pinion and escape therefrom. The segments of the commutator are arranged to alternate- 1y open and close the circuit inwhich the contacts are connected in successive steps of the pinion. Thus a stop, formed to act as a tappet to rotate said pinion, may be set of a zone of suspended joint operation, and these stops will, respectively, open and close said circuit to cause suspension and resumption of said joint operation at the beginning and end of said zone, the stops being set apart a distance corresponding to the extent of said zone.

other suitable It will be understood that means to suspend and resume joint operation may be used in connection with a pair of uniform stops for each of said zones, the invention, as related to this feature, residing mainly in the use of uniform stops, irrespective of the actuated thereby.

The Underwood-Hanson bookkeeping machine (Figure 5) includes the well-known Underwood typewriter mounted upon an 23 to print against a platen 24. The platen is mounted in a carriage which moves to and fro upon

rails

26 and 27 supported in a typewr1ter-frame28. A work-sheet 29 may be fed around the platen by the usual feed rolls 30.

In its advance movement the carriage 25 is pulled by a spring motor 31 and moves in.

letter-feeding steps controlled by an escapement mechanism actuated by a universal bar l 32, Figure 6, which in turn is actuated b the heel 33 of any operatedtype-bar. i rearward extension 34 of the universal bar engages a dog-rocker 35, which has a fixed dog 36 and a loose dog 37 controlling an escapement-wheel' 38 that is connected in the 4 usual way to a pinion 39, meshing with a letter-feeding rack 40. Operation of any typeke causes the dog-rocker to vibrate. about a fu crum 41, and in this mannerflactuates the escapement mechanism. Operation of a space-bar 42 similarly actuates the escapement mechanism by means of an arm 43,'fastened to the space-bar rock-shaft 44 actuated by the space-bar levers 44*. Said arm 43 engages an arm 45 fastenedto the cross-piece 47 connecting levers 46, which support and are actuates the dog-rocker.

actuated by the rearward extension of the universal bar. Said arm 43, in this manner, The cross-piece 47 is pivoted at its ends.

The usual Underwood denominational tabulating mechanism includes a plurality of denominational tabuating keys 48 on key-levers 49, pivoted on a common fulcrum rod 50. When a tabulating key is depressed, the rear arm 51 of the corresponding key-lever is raised and a denominational stop 52 is thereby elevated, so that its upper end 53lies in the path of tabulating counter-stops 54. Said counter-stopsare settable in a bar 55 mounted between brackets 56 projecting from the typewriter-carriage 25. In a typewriter combined with a computing mechanism the brackets 56. have upwardly-extending sides 57 spanned by. rods 58 and 59. Settable along said rods and supported thereon is a computing selector-dog 60 having a tappet 61, which, as the typewriter-carriage moves along, may en- Y. gage denominational jacks 62, which are -part of the Underwood-Hanson computing mechanism, more fully described in the aforesaid patent to Hart. Said jacks 62 are successively operated by said tappet as the typewriter-carriage moves step. 'by step through'a computingzone. The selector-dog 60 is located and set on said rods 58 and 59 to operate said jacks in said computing zone. The denominational jack when operated Said bellcauses a pin-bar, not shown, tobe positioned so that itmay-be indexed according to the numeral-key depressed. Said pin-bar sub sequently registers the amount indexed therein 1117a computing wheel 63, by means fully described in said patent, Underlying the key-levers 18 and operable thereby, by means of plunger-s .64, is a plurality of contact devices 65 supported on a plate 66, supported in the typewritor-frame 2S.

Leading from said contact devices are wires, which, with Wires from other contact devices to be described, are gathered in a cable 67, which extends toward the cardperforatorto form coupling circuits between said card-perforator and the typewriter. Included in said circuits areelectromagnets in the form of solenoids 68 (see Figure 9), which, when energized, operate the punchselecting mechanismof the card-perforator. Thus, whenever a typewriter-key is operated, a corresponding contact device 65is closed and one or more solenoids are energized.

The punch-selecting mechanism of the perforator includes a carriage 70 movable in hole-spacing steps upon guide-railsT'l and 72. The carriage is guided upon said rails by means of upper rollers 73 and lower rollers 74. Operation of any typewriter-key causes one or two of twelve plunger-s 45,.

carried by said carriage, tobe depressed by means of bell-cranks 76 operated by 'pushwires 77 encased in flexible sheaths 78, said push-wires being connected to themovable cores or plunger-s 79 of thesolenoids (see Figure 9) contained within a case 80. The perforator-carriage is pulled in a hole-spacing direction by a spring-motor 81. connected to the perforator-carriage by a strap An" escapement mechanism controls the movements of the perforator-carriage in its holespacing steps, andconsists of an escapement wheel 83 which, as the perforator-carriage moves, is caused to rotate by a pinion 84 to which it, is connected, said pnnon rolling along a stationary rack 85. The escapementwheel and its pinion are mounted on the perforator-carriage at 86. The escapementwheel 83 has teeth of apitch suitable to space the perforator-carriage.in steps of hole-spacing extent. A holding pallet 87 normally 87, but capable of moving the holding pallet by means of a pin90 which engages an extension 91 ofthe holding. pallet. The stepping pallet 89 is fastened to one end of the shaft 88. Said shaft'has its bearing in the perforator-carri age, and upon the other end holds the carriage stationary against the pull thereof isfastened a lever 92 having a cam slot 93. A pin 95 on the end of an arm 96, which extends from one side 97 of a bail mem- 'ever one of the 'punches .efi'ected by operation of the t writer-keys in the manner described.

her which includes a universal bar 98, vibrates said lever 92 when said universal bar is actuated. Said universal bar, l'ing against the bell-cranks 76, is moved w enplungers 7 5 is operated to select a punch, and consequently aetuates the escapementmechanism to hole-space the carriage every time apunch selection is made by operation of a typewriter-key. Selection of the punches is effected by means of pins 99. Wherever a punch is to be selected, one of said pins 99 is depressed by its corresponding plunger and held in its depressed position bya latch-bar 100 against thereaction of a spring 101, which restores the pin to its normal position when the latchbar is released or when another pin related to said latch-bar is depressed. There is a latchbar for each column of twelve pins. The pin 99 when depressed opposes the upward movement of its corresponding punch, said punch being one of a plurality of punches 102 supported inan upwardly-movable frame which includes a die-plate 103 and another plate 104 that guides the lower ends of the punches. The die-plate 103 and the plate 104 are separated by a gap 105,'which receives the card to be perforated. The perforating is effected by moving said' frame upward. Those punches over which a pin was not depressed and latched move upwardly with the frame and its card, while those punches opposed by the ends of depressed pins penetrate and perforate the card. This performtion is done in a machine-cycle of the pe forator subsequently to the selection of the yP After perforation, the card is ejected by. means of rollers, not shown, and deposited in a receptacle 106, while a new card isbeing simultaneously fed also by meansof rollers into ment by terminating usual tabulating place under the punches.

Regular column tabulation on the card perforator herein shown is done by releasmg its, carriage from the control of its escapement mechanism for a tabulating movement and terminating said tabulating movesaid release. This is accomplished by the usual means, which include a, lever 107 pivoted at 108 upon the perforator-carriage. Said lever has .a pin 109 which projects toward and underlies a pin 110 in the holding pallet 87. The lever 107 is rotated about its pivotby a bell-crank 111 similar to the bellcranks 76 and mounted on the same shaft 112 upon which said bellcranks 76 are mounted. The bell-crank111 has an extension 113 which overlies an arm 114 on the lever 107. The bell-crank 111 is actuated by means of a push-wire 115 connected to a plunger 116 of a solenoid 118, which, in the regular card-perforator, is energized by closing contacts underlying the key of the perforator.

In the present invention these contacts are replaced by other contacts 119. Said con tacts 119 are mounted ina suitable case 120 supported by means of a bracket 121 from the the rear of the typewriter (see Figure 5). These contacts are required to be closed whenever any one of the typewriter denominational tabulating keys 48 is operated, and there is mounted on a shaft 117, which carries the usual universal bar 117; that is actuated by the typewriter denominational steps 52, an arm 122 extending rearwardly toward the case 120. Said case has formed upon one side an upwardly-extending portion 123, upon which is pivoted a bell-crank 124, which, when rotated, will, by means of a roller 125 made of insulating material, close the contacts 119. Said contacts are normally open and mounted upon the usual resilient strips 119*. This rotation is effected by the arm 122 as it moves upwardly whenever a tabulating key is depressed. In its upward movement the end 126 of said arm, after the contacts 119 have been closed, overrides and dircctionas the end 126 of the arm again but contrariwise overrides and passes the tip 127 of the bell-crank.

In this manner operation of any tabulating key closes for a moment the contacts 119 to close a circuit to energize the solenoid 118, causing the bell-crank 111 to operate the lever 107, and consequently releasing the esscapement-wheel 83 from the holding pallet 87. The wires 129 connect said contacts in said circuit. The lever 107 is sustained in position to hold said holding pallet out of engagement with the escapeme'nt-wheel by means of a latch 130 pivoted on a tab 131 of the lever '107, said latch being caught upon a plate 132 and held thereby until the end of the tabulating movement. The universal bar 98 is also actuated by the bell-crank 111, so that when said bell-crank is operated the stepping pallet 89 engages the escapementwheel and delays the start of the tabulatmg movement of the carriageuntil the bell- In the regular card-perforator the tabulat- 7 ing movement of the carriage is terminated when a counter-stop 133 intercepts and trips 122 has passed the latch 130, thereby causing the lever 107 to reassume its normal position and the holding pallet 87 'to re-engage the escapementriage.

wheel 83. Supplementing the counter-stops 133, the present invention provides denominational stops by'meansof which the perforator-carriage is denoininationally positioned in any column predetermined by one of the counter-stops 133. Said counterstops, the same as those heretofore prov ded,

are mounted on the usual notched bar 134,

having notches spaced in hole-spacing steps.

Said bar is mounted upon the frame 135 of the perforator. The .bar 134 in the present invention has been, by means of extensions 136 (Figure 1), moved upwardly, so that there may be interposed between the counterstops 133 and the latch 130 the denomina-- Said devices include a plurality of denominational stops 137 spaced tional stop devices,

in a structure 138 which is mounted upon a bracket139 supported by the perforator-car- The structure 138 is slidable on said bracket by means of slots 140, through which pass shoulder screws 141 fastened into and supporting the structure 138. A sprin 142 normally keeps the structure toward the 5 right.

The denominational stops 137, spaced by suitable means according to hole-spacing steps of the perforator-carriage, are pivoted upon a rod 143 mounted in the structure, 138.

The stops 137 have arms 144 which extend rearwardly and are notched at the'ends for applying springs 146 anchored to a springplate 147 fastened to said structure. Said spring 146 on the stop and its arm 144 about the rod 143', so that the stop 137 tends to assume a position in which it may be intercepted by a counter-stop as the car-. 0 riage moves. Four stop-selectors 149, un-

derlying the lower edges of the arms 144 and extending transversely thereof, have formations-148, which, in the normal positions of said selectors, oppose said rotation. Said formations on each selector are so co-ordihated to the formations on the other selectors that, when a'propercombination of the relative positions ofthe stop-selectors is effected, an opcningis presented that will permit the arm 144 and consequently the stop 137to rotate. To provide such an opening either one or two of the selectors are shifted from nor mal position. A group of four selectors affords ten different combinations of their relative positions by shifting one or two selectors and in each of these combinations the formations on the selectors afford an opening for the rotation of a corresponding denominational stop.

In Figure 8 the denominational stops 137 I are designated by numerals from 1 to 9, inelusive, and the four stop-selectors 149 are designated by the letters A, B, C and D.

The stop-selectors are held in normal positions by springs 149. Each selector, slidably mounted in the structure 138, is shiftable by means which include a slug 149"fas tened to oneend of a push-wire 150 connected at its other end to a plunger 151 of a solenoid 152 contained in the case 152.

The push-wires 150 are encased in flexible The arms 144 bear upon the stop-selectors 149 through the tension of the springs 146, and means must be provided to hold said arms clear of the selectors while said selectors are being shifted by operation of-a tabulating key. As already explained, the bellc'rank 111 disengages the holding pallet 87 from the escapement-wheel 83 when a tabulating key is operated. Said bell-crank also One or two of said solenoids are energized whenever oneof the tabulating operates the universal-bar 98, which, by

153, which may raise a rod 154 supported by arms 155 fastened to the rod 143, about which the denominational stops 137 rotate. Said lever raises said rod 154 by engaging an extension ,156 of one of the arms 155. The bell-crank 111 and consequently the universal bar 98are held in operated position for the greater part of the tabulating keystroke or until the contacts 119 open'toward the end of said .stroke. In this operated position, by means of said link 159, lever 153 and rod 154, the arms 144 are held clear of the stop-selectors while they are being shifted. Toward and at the end of the stroke of the tabulating key, the rod 154,

when the contacts 119'open, reassumes its normal position by means of a spring 154,

allowing" the arm of the selected stop' to fall into the opening afforded by the formations of the shifted stop-selectors. In the meantime a. tabulating movement of the perforator-carriage has been initiated, andthe selected step 137, now moved into effective means of a link 159, is connected to a lever position, isintercepted by one of the counter-stops 133. This interception, followed by a continued movement of the perforatorcarriage, causes a relative movement between the structure 138 and its supporting bracket 139, which, in efiect, is a relative movement between said structure and the perforator-carriage. This relative movement causes a tappet 158 to' strike and trip the latch 130. Said relative movement of the structure occurs against the tension of the spring 142. The tripping of the latch 130 permits the holding pallet 87 to reengage the escapement-wheel and thereby end the tabulating'movement. Said tappet 158 is pivoted at 158 so that it may be swung upward if the latch is underneath it during a carriagereleasing movement of the lever 107. e

, The Underwood back-spacing mechanism includes a back-spacekey 160 on a leverstud 165. When the bee -space key is operated and the draw-link 163 pulled downwardly thereby, said bell-crank rotates about its pivot, and the end 168 thereof, toward the end of the back-space key-stroke, closes contacts 169. Said end 168 is in the form of a roller or button made of insulating material. Said contacts 169 close a circuit to energize a solenoid 170. Fig. 7. to operate means for back-spacing the perforator-carriage. Said contacts 169 are. mounted on the a bracket 166 and suit-ablv insulated therefrom.

Pivotally connected to the plunger 171 of said solenoid 170 is one end of a link 172. The other end of said link is pivotally connected to a bell-crank lever 173 pivoted upon abracket 174 fastened to the perforatorframe. By means of a spring 175, said bellcrank 173 is held in normal position against a pin 176 driven. into said bracket. Said bellcrank 173 when rotated by the solenoid 170 causes a toothed-bar 177 to rotate about a' longitudinal axis. so that teeth 178 on'said j bar engage a' projecting member 179 on the perforator-carriage. Said tooth d bar when thusengaged is then given a longitudinal movement to effect a back-spacing step of the perforator-carriage. The bar thus has a double movement.first. to engage said projecting member. and then to move. in a backspacing direction. To accomplish said double movement, the bar is provided with trun,

nions 180 bearing in brackets 181' and 182 fastened to the perforator-frame. Said mm.

nions are also slidable longitudinally in' said brackets so that the bar may move in a backspacing direction. A shoulder 184 of the trunnions stops against the side of the bracket 182, and thereby limits the backspacing movement of the bar. With proper formation of the teeth 17 8 and the endwise movement of the bar thus limited, overthrow of the perforat-or-carriage in backspacing is substantially prevented. In order that the bell-crank 173 may swing the toothed bar 177 into engagement with the projecting member 179, one trunnion member of said bar is provided with a cam-block 183 engageable by the rounded edge 185 of an arm 186 of the bell-crank 173. Said edge 185,

working against a suitably-inclined camsurface of said block, causes the bar to Totate about its trunnions until one of the teeth 178 engages the projecting member 179, as shown in Figure 19. A further movement of the bell-crank, at the beginning of which the edge 185 has encountered ashoulder 187 of the cam-block, causes a back-spacing movement ofthe bar which is transmitted to the carriage and 'is completed, as shown in Figure 20. Figure 18 shows the toothed bar 177 in its normal position in which it is held by an obliquely-pulling spring 188, the pull of which has two components,-onebeing I eifective to swing the. bar about its trunnions and disengage it from the projecting memher, and the other component being efiective to restore the bar after a back-spacing movement by sliding it along the trunnions 180. Figure 21 shows an alternative construction of a toothed back-s acing bar 190. An advantage of this form of bar is that the disengagement of the teeth from the-projecting member is facilitated by a more direct recession of said teeth Y from said member I when the bar is disengaged. The teeth in any form of bar are spaced accordingto the hole-spacing steps of the perforator-carriage.

Included in the main circuit supplying the solenoids, by means of which the card-perforator and typewriter are coupled, is a contact device 191 normally closed and connected in said circuit, by means of wires 192. Said contact device is supported by a bracket 193 fastened to acasing 194, which forms part of the computing mechanism. Bearingin said'b racket is a plunger 195. which bears upon an insulated, extension 196 of a resilient member 197 of. the contact device. When i said plunger is in depressed position, the contacts 198 are open and the'main circuit thereby broken. When said circuit is broken. joint operation between the typewriter and the card-perforator is suspended. This suspension of joint operation is necessary while writing certain portions of a line of data on while said portions are being writtien.

To automatically predetermine brackets 201 fastened to the upstanding sides -57 of the brackets 56. Said stops 199 have surfaces 202 of varying lengths correspond-.. mg to the extent 0 the zones in which joint operation is to be. suspended. If joint operation is to be suspended for one step of the typewriter-carriage and resumed in the following step, one of said surfaces must be an edge 203, see Fi re 4. Inclined camming I edges 204 facilitate the depression of the plunger 195. V v y In the step in which the typewriter-carriagemoves from a zone in which'j'oint. operation; was suspended, the surface or edge passes from the plunger 195, permittin the I typewriter-carriage alone moves. If, at the 3 contacts close, so that the next .stro e of a t pewriter-key also 0 erates the cardper orator mechanism. 11 said step the end of said step, the typewriter-carriage is to back spaced by operating the back space (key 160, the contacts 198 must beopened before the stroke of the back-space key can close the contacts 169,;or'else' the rforator-carriage will be'back-spaced also. i

t isfor this reason that the contacts 169 are closed only atthe end 'of the back-spacing key-stroke, so that,,when the typewriter-carriage is lbaek-spaced-intoa zone of. sussaid main circuit is open. A fu 1 pended joint operation, the contacts 198 are opened before the ,eontacts 169 close. Said.

7 The well-known Underwood carriage-re.

turn mechanism as applied tovth'e Underwood-Hanson bookkeeping machine is driven by the motor, not shown, of said bookkeeping mahine. A belt 205 runsfrom said motor to a pulley 206 fastened toone end o a shaft bracket 208 sup orted' on" theltypewriterframe Keye' to said shaft is aclutchmember 209 engageable by another clutch- 207, which has its bearing in a :member 210 which is slidable on said shaft 207. Said other clutch-memberhas pinion teeth 211 which mesh with and drive a rack 212 fastened to the typewriter-carriage 25. The clutch-member 210 is slid into engagement with the clutch-member 209 by means of a lever'213 fastened to a shaft 214., The engagement of said clutch-members may be effected automatically as the carriage moves in the last letter-feeding step which terminates a line of writing. In said last step a link 215 is caused to be thrust downwardly by means shown in the patent to .Richard F. Hoyt,,N 0. 1,238,919, dated September 4, 1917. As said link is thrust downwardly, it depresses one end of a lever 216 mounted on a pivot 217 fastened in the typewriter-frame 28. The other end of said leveras it rises encounters a pin 218 fastened in the side of a link 219, and thereby raises said link 219, so

that a notch 220 on said link escapes from its holding edge in a'plate 221.. The link 219 thus freed is pulled rearwardly by a spring 222, and, by means of an arm 223, rotates a shaft 224. Said shaft 224, by means of an' arm 225 and a link 226, rotates the shaft 214 to 'efl'ectengagement of the clutch-members. In this manner the clutch-members are automatically engaged after the carriage has taken its last letter-feeding step, and the carriage is then returned to its. starting place.

At the end of the carriage-return movement, means, shown insaid patent to Hoyt,

rotate a shaft 227 and said rotation, by means of links 228. and 229, is transmitted to the shaft 214 to effect disengagement of the clutch-members. 3 a

A carriage-return movement may be also initiated by depressing a carriage-return key 230, which is mounted upon a lever 231 pivoted to the typewriter-frame 28 at 232. An arm 233 of said lever as it vibrates raises and frees the link 219 to actuate the train of parts described. Simultaneously with the engagement of the clutch-members 209 aiidf 210, contacts within a case 234 are caused to be closed by the rearward movement of a bar 235 connected to the shaft 224.

Means whereby initiation of a carriagereturn movement also causes a cycle of .the perforating machine-to'be initiated are pro: vide'd. 'Said. perforating cycle isnusually initiated by a perforator trip-key 238 at the typewriter keyboard, which, when operated, closes'contacts 239, see' Figure 9, to close a circuit to energize .the usual solenoid 240, Said solenoid 240 when energized'releases a clutch-member 241' (Figure 17 on the per-' forating machine. Said clutch-member 241 when released couples a main driving shaft 242 of the perforator to a driving disk 243 geared to a shaft 244 of amotor generator" 245.- Said'main driving shaft has a commutator 246 which, toward the end of one revolution of said shaft, bridgesj'contacts- 247 to effect the return 0 to close a circuit to energize another solenoid 248 (not shown in Figure 9). Said solenoid 248 when energized trips a clutch-releas1ng 'member 248 to engage a clutch 249 by means is held in normal position by a spring 255 which normally pulls in a line passing through the pivot center ofthe bell-crank, so that said spring is effective to return the bellcrank to its normal position, irrespective of the direction of rotation of the bell-crank.

' As the bell-crank is rotated by the rearward sweep of the extension 250, a roller 256 there on, made of insulatingmaterial closes for a moment the contacts 257. Said contacts 257,

as already stated, bridge the contacts usually actuated by the regular pertorator trip-key 238. A switch 259 may be provided an conneeted in a bridging circuit 260. Then said switch is open the contacts 257 are inefiective to energize the solenoid 240, and consequent,

1y, when a typewriter carriage-return movement is initiated, sald solenoid Wlll not be energlzed when said switch is open.

All solenoids herein mentioned are referably designed to operate on a low-v0 tage direct current, which may be supplied by the motor generator 245.

Figure 22 shows means whereby the main circuit may be opened and closed to auto matically suspend and resume joint operations, said means being one way of enabling the use of uniform stops. There may be provided accordingly a bar 265 which would replace the bar 200, and, on said bar, uniform stops 266 may be set-in positions cor responding. to the beginning and end of a 'zone of suspendedjoint operation. -A bracket 267 may be iastened' to the casing 194 in place of the bracket 193.- Said bracket 267 forms a bearing for a shaft 268. upon one end of which is formed a six-tooth pinion 269. Said stops 266 have tappet formations 270, whereby, as the typewriter-carriage moves, said pinion'may be rotated.

. The number of teeth of said pinion 269 is limited preferably to six, so that, in one letter-feeding step of the typewriter-carriage, said tappetformations may engage and rotate said pinion one step and escape therefrom. A" spring-pressed. detent 271 lightly presses between adjacent teeth of the pinion'and locates said pinion at each step.

- into a zone 0 a commutator havin se ents 2720f conducting material, eac i 9 which may bridge insulated from one another and from the The commutator should be made as light as possible to'prcvent overt-brow due to inertia. Said contacts are connected in the main circuit by means of wires 274. Itwill be seen from Figure 22 that said main circuit may be alternately opened and closed by successive steps in the rotation of the pinion 269. Thus a stop 266 properly set will, in the ste in which the carriage moves i suspended operation, rotate said pinion and cause the circuit through said contacts and one of said segments 272 to be opened as said segment272 is rotated away from said contacts. In the step in which thecarriage moves out of said zone of suspended oint operatlon', another stop, properly set,

will rotate the pinion 269 through another step, bringing the succeeding segment under the contacts. The stops 266 are set ,apart a distance corresponding to the extent of the zone in which joint operation is to be sus pended, a pair of stops being used to define the beginning and end'of each zone.

The space-bar 42 of the typewriter, when operated, closes contacts 277 to energize a solenoid 278 (Figure 9) Said solenoid,by

means of a push-wire 279 (Figure 3), actuates the universal bar 98 to effect a spacing 'step of the perforator-carriage 70.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

1. The combination with a typewriter having a letter-feeding carriage, a card-perforator having a hole-spacing carriage, a denominational tabulating mechanism on said typewritencontrolled by a plurality of denominational keys, and electric coupling means whereby said typewriter and cardperforator may be jointly operated, and wherebj the perforaton-carriage is caused to mm in unison with the typewriter-carriage uring the type-key operations, of means whereby operation of said denominational keys to position the typewriter-carriage may also cause said erforator-carriage to be co-relatively but issentaneously positioned.

2. In a combined typewriting and cardperforating machine, the combination with a steps, and a denominational tabulatin mechanism controlled by denominationa keys for tabulat ng said typewriter-carriage,
