Original application filed May 12, 1910, Serial No. 560,927. Divided and this application filed October 15,

To U '107mm t may concern Be it known that I, lVALTnR lVnreH'r, a citizen of the United States, residing in New York, in the county of New York and State ot New York, have invented certain ew and useful Improvements in Combined l`ype-llriting and Computing Machines, of which the following is a specilication.

rlhis invention relates to an improvement in combined typewriting and computing machines vof the Underwood-lVright type, and is a division of myvapplication, Serial No. 580,92?, iiled May l2, 1910.

The present case includes certain portions et said parent. case which relate more particularly to the accumulating of a series o1 crossftotals in a plurality of individual totalizers. There may also be used one or more main totalizers, and all the totalizers may be connected 'to move with the traveling t},f'pewriter carriage, the main totalizcrs for a continuous run of the carriage, and the cross otalizers for intermittent back and iorth movements during such continuous run. The main totali-zers may be. merged into a single long totalizer capable of division or grouping in various ways.

@ther features and advantages will hereinafter appear.

Fig. 13 is a view similar to that shown in Fig. l2, except that-the hooks have been disconnected from the numeral keys.

Numeral keys l operate type-actions in a manner common to the Remington typewriter, to print digits on a work-sheet carried bya platen 2. rEhe platen 2 is mounted to rotate on a carriage 3, which travels on a frame et. Although the mechanism is shown as applied to a Remington machine, it can just as well be applied to an Underwood machine, or any other similar make. rlhe carriage Shas the usual step-by-step traveling movements to space between the writing et the digits and other characters. This movement may be controlled by any well-known escapeinent mechanism.

The numeral .keys l, in addition to typewriting the digits, are arranged to compute them by running the numbers up into totalizers 5, 6 and 7. As will be explained more fully hereinafter, the totalizer is a long totalizer, having a large number ot' computing wheels S, which may be separated into groups, to add up vertical columns of numbers, each comprising several digits, as they are typewritten. rEhe short totalizers 6 and '7 are cross-totalizers and arranged to sum up the horizontal columns of numbers as they are typewritten.

1n the present case, mechanism for adding and subtracting is'shown. In order that the numeral keys 1 may compute as well as typewrite, when any one of them is depressed., its key-lever 9 draws down on a hook 10 to rock a bell-crank 11, which is connected by a link 12 to actuate a bellcrank 13, arranged to operate a plunger or jack 14. There is one of the plungers or jacks 14 for each of the numerals from 1 to F 9 and they are arranged in a circular series, so as to set opposite ones of a series of pins 15 mounted in a pin-wheel 16.

All but one of the pins 15 normally occupy a position projecting from the side of the pin-wheel 16 next to the plungers or jacks 14, and are arranged to be projected individually to the opposite side of the pin-wheel 16, so as to determine the rotation of the pin-wheel 16. This gives an indexing or valuating movement of the pin-wheel 16, which corresponds in its extent to the'value of the particular numeral key actuated. The extent of movement 'is determined by the distance of the pin set from the pin which was previously set and maintained by the wheel 16 in a locked position subsequent to the previous computation. The pins 15 are yieldingly lock d in either of their positions by a circular spring,17, which engages alternately in sockets 18, provided in the pins 15.

The pin-wheel 16, whenv no numeral key is actuated, is locked by a star-wheel 19, engaging the last set pin, indicated specificallyy at 20, Fig. 8, which determined the extent of the just previous computation. The pinwheel 16 isnormally under a driving tendency to rotate from a motor 21, and will ro tate when released by the star-wheel 19. The driving connection includes a slipping mechanism, whereby the motor 21 can continue to rotate when the pin-wheel 16 is locked by the star-wheel 19. This driving connection includes a motor-shaft 22, having a series of spring-clutch-shoes 23 secured thereto, which are arranged to engage in a clutch-cup 24 secured to a shaft 25. The shaft 25 is provided with a beveled gear 26, which meshes with a beveled gear 27 secured to a shaft 28, having a gear 29. The gear 29 drives a. gear 30, which, in turn, drives a gear 21 on a shaft 32, to which the pin-wheel 16 is secured. Ordinarily, the pin-wheel 16 is held against rotation b-y the star-wheel 19, so that a slip takes place between the clutch element 23` and the clutch element 24. ldhen, however, the star-wheel 19 is permitted to turn so as to'permit a rotation of the pinwheel 16, the pin-whee 16 will rotate an amount correspondingto the numeral key just actuated, which rotation will be carried in a manner, presently to be described, into one or more of three totalizers 5, 6 and 7. The pin 15, which previously locked the wheel 16 against rotation, will be unset as it escapes from theA star-wheel 19 by a cam 33, lying in the path of this previously set pin.

In order to release the pin-wheel 16 at the actuation of the numeral keys from 1 to 9,7 each of the links 12 is provided with a head 34, which engages a plate 35, universal to all of the heads 34. This plate is forced backwardly at the actuation of any one of the pin-setting linkages by its numeral key, so as to rock a link 36 against the tension of a spring 37. The link 36 has connected to its other end a link 38, which operates an escapement mechanism 39 for a shaft 40, on which the locking star-wheel 19 is secured. This escapement mechanism is more fully described in the parent application, and also in mv Patent No. 1,244,397, dated October 23, 1917. The operation is such, however, that at each depression of any of the numeral keys from 1 to 9, the locking starwheel 19 is permitted to turn a quarter of a. revolution, so as to permit the escapement of the previously set pin 15, and thus permit a rotation of the valuating or indexing wheel 16 until the just set pin 15 comes into engagement with the star-wheel 19 and brings the pin-wheel 16 to a halt.

This valuating or indexing movement is transferred to the computing wheels of the totalizers 5, 6 and 7. To do this the pinwheel shaft 32 is provided with a beveled gear 41, which meshes with a beveled gear 42 secured to a shaft 43. The shaft 43 is arranged to drive a vertical shaft 44 through the intermediary of a train of gearing which permits the shaft 44 to be disconnected from the shaft 43, so that any computing, driving action of the motor 21 may not have its eect on the computing wheels of the totalizers 5, 6 and 7. Tn the parent case, this had a particular purpose in varying the driving ratio between the shaft 43 and the shaft'44, so as to eiiect multiplication and division. This train of gearing includes a gear 45; loose on the shaft 43 and meshing with a gear 46 secured to a shaft 47. The gear 46 drives a gear 48 secured to a shaft 49, on which a beveled gear 50 secured, which, in turn, meshes with and drives a beveled gear 51 secured to t-he vertical shaft 44. The gear 45 is loose on the shaft 43 and is connected thereto by means of a clutch 52, including an element 53 secured to the gear 45 and engageable by an interlocking clutch element 54, splined on the shaft 43. The clutch element 54 is normally held in mesh with the clutch element 53, by means of a spring 55. To disengage vthe clutch element 54 from the clutch ele- -ment 53, so as to interrupt the connection between the driving shaft 43 and the drive-n shaft 44, there is provided a key 56, located at the front of the machine and having a key-stein 57, projecting past a disk 58 secured to the clutch element 5t. rlhe keystem 57 is provided with a lug 59 which engages the disk 58, and, when the key 56 is operated, disconnects the clutch -l against the tension of the spring 55.

The 'shaft del is arranged to carry the indexing or valuating movements of the pin- Wh'eel 16 into the computing Wheels 8 of the totalizers 5, 6 and 7. For this purpose, there is loosely mounted on the shaft del three sets of beveled gears, indicated specifically, in F ig. 3, by the numbers 69 to 65. The beveled gears are arranged'in oppositely-facing pairs which mesh with beveled gears 66, 67 and 68 secured to master-Wheel-shafts 69, '70 and 71, respectively. Each of the master-Wheelshafts is provided with a master Wheel, indicated specifically, for the totalizers 5, 6 and 7, by the reference numerals 72, 473 and 7st, respectively. The pairs of gears 60, 61; 62, 68; and 6a, 65 are loosely mounted on the vertical shaft del and arranged to be connected in driven relation with the shaft Llei *by means of clutches '75 splined on the shaft 44, one loc-ated between each of the pairs of oppositely-facing beveled gears. Each of the clutches may be .shifted from an intermediate, disconnected, neutral position upwardly or downwardly into clutching engagement with the upper or lower beveled gear of each pairso as to secure the same in driven relation With the shaft When shifted in one direction to connect one of the beveled gears with the shaft tl., the associated master Wheel Will be driven to add, and when shifted in the opposite direc Vtion to clutch the other. beveled gea-r to the shaft 44, the associated master Wheel will be -driven to subtract.

The. computing` Wheels 8 of the totalizers have associated with them tens-carrying trains of gearing for carrying l to the next higher computing Wheel When any particular computing Wheel completes a revg elution. This tens-carrying mechanism is driven from the motor 21, and is controlled in its rotation and direction of rotation concomitantly with the control of the rotation and direction of rotation of each master wheel by the clutches 75. For this purpose, each of the totalizers 5, 6 and 7 is provided with a tens-carrying shaft carrying at its end a beveled gear 76. Each of the beveled gears 76 meshes with and may be driven by a pair of oppositely-facing gears 77, 78. The gears 77, 78 for each of the totalizers 5, 6 and 7 are loosely mounted 0n a vertical shaft 79, and are connected to the shaft 79, similarlv to the gears 60 and 65, by means of clutches 80, one individual to each of the pairs of beveled gears 77. 78. rlhe clutches 80 are splined on the shaft 79, and are shifted with the clutches 75 so as to give rotations of the tens-carrying mechanism correspending to the rotations of the master ivheels. r)The clutches 75 and 8O for each of the totalizers 5, 6 and 7 are shifted concomitantly, for the purpose just mentioned, by means of levers 81, 82 and 83 for the totalizers 5, 6 and 7, respectively. rhe shaft 79 is driven from the motor 21 by means of a train of gearing including a beveled gear 8l secured to the shaft 79 and meshing with a beveled gear 85 secured to a horizontal shaft 86. rlhe shaft 86 is connected in driven relation with the motor shaft 22 by a gear 87 secured to the shaft 86 meshing With an intermediate gear 88, vvhich is driven b v a gear 89 secured to the motor shaft The train of gearing from the motor shaft 22 to the shaft 79 is to one side of the train of gearing from the motor shaftto the master wheels. Thus, the tens carrying mechanism may be rotated independently of the particular valuat-ing movements of the master Wheels if they are connected by the clutches 80.

rEhe master vvheels 72, 73 and 7st are arranged to travel With the carriage 3, so as to come into register step by step with the computing Wheels 8 of the associated totalizers. rlhe master Wheel '72 travels continuously from left to right ivith a continuous traveling movement of the carriage 3 from right to left. The maste wheels 73 and 7l travel from left to right step by step, and then turn quickly several times for one continuous traveling movement of the carriage 3 from right to left. To effect this traveling movement of the master Wheels- With the traveling of the typewriter carriage the typewriter carriage 8 is provided at the rear thereof With a rack 90, Fig. 5, meshing vvitfh and driving a gear 91 secured to a vertical shaft 92. rlhe shaft 92 is provided ivith a gear 93 driving a gear 9d on a shaft 95, Which is provided at its forward end with a gear 96 meshing with a rack 97 secured to a master-wheel carriage rlhe train of gearing from the typeivri'er' carriage 8 to the master-Wheel carriage 98 is suoli that vrh the typewriter carriage advances step by step in letter-feeding direction from right to left, the master-Wheel carriage 98 vill advance concomitanti)v step by step from left to right.

The master Wheel 72 connected to a sleeve 99 provided on the master-'Wheel carriage 98, so that it Will travel with the carriage, and is slidingly mounted on the master-Wheel shaft 69, so that it can travel along the same. The engagement of the shaft 69 with the master ivheel 72 is angular, so that, although the master uiheel 72 travels along the master-Wheel shaft 69, it will rotate with the latter. This enables the master Wheel 72 to come into register one by one with each of the computing trains represented by the computing or dial ivheel 8 showing at the sight-opening of the totalizer The position of the master wheel 72 at any particular moment is indicated by a pointer 100 secured to the master-wheel carriage 9S and located in register with the master wheel 72. The master wheel 72 travels inside of the computing wheels, which are provided with internal gears, in a manner more particularly described in my abovementioned application and patent. This position, however, is accurately determined at any time by the'pointer 100.

To give a concomitant step-by-step movement to the master wheels 73 and 74, they are slidingly mounted on the gear shafts and 71 and connected to be traversed by sleeves 101 and 102 forming part of a master-wheel carriage 103. r1`his forces the master wheels 7 3and 71 to move in unison. The master-wheel carriage 103 is traversed from the master-wheel carriage 98 by means of a shifter 104, which is intermittently connected to the master-wheel carriage 98. For this purpose, the master-wheel carriage 98 is provided with a bar 105 having a series of openings 106 located at intervals from each other. Pick-up stops 107 may be adjustably secured along the bar 105 by means of pins 103 secured to the stops 107 and extending into the openings 106 in the bar 105. The piel;- up stops 107 are each provided with a lug 109, which is arranged to engage in a notch 110 formed between shoulders 111 and 112 provided on Athe shifter 101.

The pick-up stops 10T are adjusted along the bar 105 according to predetermined positions of the vertical columns of figures to be typewritten on the work-sheet carried by the typewriter carriage 3.

The usual starting position of the masterwheel carriage 103 for the short totalizers 6 and 7 is that shown in Fig. 1, with the master wheels 73 and 741 in register with the highest computing wheels of the totalizers 6 and 7 This position is determined by a .pring barrel 113 connected to the masterwheel carriage 103 by a clutch connection 114. Each of the pick-up stops 107 engages successively in the notch 110, so as to connect the shifter 104, and thus the masten wheel carriage 103, in traveling relation with the master-wheel carriage 9S, so that the master wheels 73 and 71 are advanced step by step, against the tension of the spring barrel 113, with the travel of the long-totalizer master-wheel carriage 98. The master-wheel carriage 103 travels for the length of the short totalizers 6 and 7 so as to have a concomitant computing action in the wheels of the short totalizers 6 and 7 with several sect-ions or groups of computing wheels of the long totalizer 5.

When the master wheels 73 and 74 have computed in the units computing wheels of the totalizers 6 and 7, the carriage 103 is disconnected from the long-totalizer masterwheel carriage 98 by withdrawing the shifter 101 from engagement with the particular pick-up stop 107 with which it happens to be connected. This is done by the disconnector 115 lying in the path of a cam 116 provided on the shifter 104. The disconnector 115 acts against the tension of a spring 117, which normally holds the shifter 10e in such position as to cause it to connect with the particular pick-up stop 107 with which it happens to be in register. Thus, the master wheels 73 and 711 are advanced step by step with the advancing movement of the master wheel 72, so "as to compute in the totalizers 6 and 7 with a concomitant Computation in the several sections of the long tota-lizer 5. The master wheels 73 and 7 L1 return after computing in the units computing wheels, so as to be ready to compute in synchronism with the computing wheels of the next section of the long totalizer o. rThis is repeated for each section of the long totalizier 5, until the end of the typewritten line and the last section of the totalizer 5 are reached.

To prevent over-return movement of the vibrating master-wheel carriage 103 with the continuous return movement of the master-wheel carriage 98 and the typewriter carriage 3, the pick-up stops 107, when they engage the shoulder 111, force a cam 118 on the shifter 101 into engagement with a disconnector 119, so as to depress the shifter 101 against the tension of the spring 117, and thus clear the shifter from the particular pick-up stop 107 in register therewith.

When the carriage 98 of the master-wheel 72 returns to the left with the movement of the typewriter carriage to the right for the purpose of beginning a new line of writing, a special lug 120 on the 'column stop bar impinges against a pin 121 secured upon the right-hand end of a rack 122. Said rack engages the upper side of a pinion 123, the lower side of which is engaged by a lower rack 125, and, therefore, moves to the right as said frame moves to the left. A spring 12st around the shaft of the pinion 123 normally moves the rack 125 to the left and the rack 122 to the right. The rack 125 has a shoulder or extension 126, which, when it is moved to the right, engages a pin 127 eX- tending from the cam 118, and therefore moves to the right with said rack the shfiter- 104 and the horizontal master-wheels 73 and 741 through the full distance of their travel to the right, and until the sloping advancing edge 116 of the shifter 10a is engaged by the disconnector 115, which thereupon depresses said shifter and detaches the pin 127 thereon from the'shoulder 126 on the rack, so that the shifter 104e returns to the left under the action of the spring barrel 113. On its return it is arrested by the projection 109 on the first of the series of column stops engaging the notch 110 on said cam 118. llVhen the carriage 9S re-commences its movement to the right the Vupper rack 122 follows its movement under the tension of the spring 124 until it reaches its normal position.

The object of the above arrangement is to permit a column of any width, from three to twelve figures7 commenced at the first writing space of the typewriter, to be computed in either or both of the horizontal computing mechanisms along with other columns of the same or greater or less width which are computed in the long totalizer. lere this mechanism not provided that result could not be obtained, for, although it would be possible to write'a column, say, of three figures wide, at the eXtreme left of the writing space, and to actuate theV first group of three wheels of the horizontal computing mechanisms in correspondence with the writing of the figures of said column, yet said wheels so actuated would not be the proper` wheels to be computed with other columns of greater width. For instance, hundreds. tens and unit-s might be added, respectively.y to hundreds of thousands, tens of thousands and thousands. By the above contrivance it is provided that, when a column of three figures or less is to be computed at the eXtreme left of the writing' line, it is only the computing. wheels on the eXtreme right of either one or both of the horizontal computing mechanisms that are actuated. 1f a. column six figures wide is written, then the six wheels on the extreme right of either or bot-h of the horizontal computing mechanisms are actuated and so on. thus assuring that in all cases the computing wheels or either or both of the horizontal computing' mechanisms will correspond in denominational value to the several figures of t-he columns.

The numeral keys 1 mav be disconnected from the valuating; orvindexing mechanism bv diserqrraging` the hooksl 10 from the brackets 128 attached to the keV-levers 9. Fig. 1, in the manner fullv disclosed in my aforesaid Patent No. 1,244,897.

l'n addition to this mechanism. there is provided means to permit the type-bars to be entirelv disconnected from the numeral keys, so thatl computing may be done wit-houttypewriting. Y For this purpose.y brackets 128a are provided on the key-'levers 9. said brackets having eyes which may be engaged hy hooks 10a connected to the links 125 which operate typebars 13. There is also provided a horizontal bar or rack 130 having at its ends slots whereby it is mounted on headed studs or screws secured to the base of' tho typewriter. said rack having a finger-piece 134. whereby it may be shifted endwise. This rack or bar has forwaidly-extending fingers, each of which may be forked or slotted al; 129 to bcstride the hook 10a to shift the same laterally. or in a direction across the key-lever system. When the rack or bar 1.23() is pulled from the position at Fig. 12 to the position at Fig. 13, where it is detained b v notch and spring' 131) the hoo-hs 10 are shifted out of engagement with the eyes in the brackets 128a7 so that the keys may be manipulated for computing purposes without writing'. Y

The device may be made to compute both vertically in several computing zones or major columns, and horizontally for cross and gross totals. The long' totalizer 5 mayT be divided into sections or groups which'compose individual computing heads. The dividing is taken care of by the positioningof the typewriter carriage for the several computing zones or columns. The stops 107 are preferably located along the bar 5 to pick up the cross and gross totalizers 6 and 7 at predetermined intervals to correspond with the grouping of the computing wheels of the long` totalizer 5. The cross and gross totalizers 0 and 7 will add horizontally the lines of numbers which are added vertically in the long totalizer Each of the totalizersI 5, 6 and T is separately controlled by thel levers S1, 82 and 83. so that various combinations of adding, subtracting and neutral of the three totalizcrs can be had. This provides interruption of the drive from the indexing or valuating' mechanism at each totalizer, so that any or all of them can be silenced. .ln additionE the drive to Jthe shaft 44, which is common to all of the totalizers, can be interrupted by shitting' the gear 4J out of mesh with the gear L16. rfhis will silence all of the totalizers. Thus. any one of the totalizers may add or subtract, or be silenced. and all of the totalizers may be silenced at a common point.

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