COMBINED .TYBEWRITING AND COMPUTING MACHINE.

T0 allauhomit concern Be it known that I, -GLIFTON B. CQRELL, a citizen of the "United States, residing in New Yorkcity, in the'county ofNew York and State of New York, have inventedcer-' tain new'anduseful Improvements in Combined Typewriting and Computing Ma chines, of which the following is a speci fication.

This invention relates to combined typewriting and computing machines, and is herein disclosed a's'appliedto a machine of the Underwood Addendagraph type having not only a :typewriting carriage but also a cross-adding carriage, and means for con-e necting thetwo carriages atadjustable predetermined positions. Y

In such machines,=one form of which is disclosed in application of Henry L. Pit.- man, No. 186,098, filed August 1 1, 1917, there is usually provided a rack bar having settable column-stops thereon, and a second rack bar having settable dogs thereon, the latter rack bar being-adapted to pick up by its set dogs the cross adding carriage. In the form of the machine disclosed in said applicatiolnthere are provided two setting arms,'one to set the stops or dogs on each rack bar.

According to the present invention, a single device mayserve as'a finger-piece for setting the stops or dogs on either of the rack bars, the way in which the finger-piece is manipulated determining on which rack bar the setting maytake place. To effect this, it has been found advantageous to pro vide a single shaft which may be rocked in one direction to 'set the column-stop on one rack bar, and in the other direction to set the stop or dog on the other rack bar. For

rocking this shaft, the :fingenpiece may advantageously take the form'of a lever at the side of the machine adapted to be rocked either forwardly or backwardly.

Other features and advantages will hereinafter appear.

Alphabet keys 15 and numeral keys 16,

when'depressed,swing key-levers 17 to roclr' bell cralnks 18 about a fulcrum rod 19, to

swing type-bars 2O upwardly and rear wardly about a fulcrum 21, to cause types 22 to strike against the 'frontside of a rotatable platen 23. The platen 23 is mounted for line-spacing movements, of a worksheet, not shown, on a carriage 24, which travels back and forth on a front rail 25 and'a'rear rail 26. T V

For itsletter-feedi'ng movements,the carriage 24: is provided with a feed-rack 27 which meshes with a pinion 28 to rotate the latter. The pinion28 isconnectedto rotate an escapement wheel 29 by the usual oneway acting pawls 30. The escapement wheel 29 is provided with teeth 31, which alternatelyengage with a loose dog 32 and a fixed dog 33 on a dog-rocker34t when the latter is vibrated by a universal bar 35, engaged by heels 36 of the type-bars 20 when the latter approach the printing point. The

upper end'of the dog-rocker is returned to' its forward or normal position, as in'the Underwood typewriter, by the usual spring (not shown)- j The carriage 2 1may be rapidly moved to bring any denominational position of a column on the platen to the printing point. To do this, there is provided a series of tabulator-keys 37, any one of which, when depressed, swings an associated lever 38 to move a plunger 39 to bring the upper end thereof, comprising a denominational "stop 4.0, into the path of effectively-set column-. I

stops 41 on a stop-bar 42 secured to the typewriter carriage by brackets 43. The

usual rack-releasing means including the short universal bar l tmay be actuated by the usual heels't'5, so that the plungers 39' will draw down the usual link 16, and there by rock the lever 17 to lift the'rack 27 out of *the pinion 28. This lifting of the rack 27' frees the carriage from the escapement wheel 29 and permits the usual spring'drum her itselt on any l8 to draw the carriage along to the left until it is arrested by the said stop ll.

Computing may be accomplished by the numeral keys 16, each being provided with a differential or indexing cam 4L9, which, through connections, not shown herein, but similar to the connections in the aboreunentioned application of Henry L. litman, Serial No, 186,098, may turn the usual mastor-wheel 50, so that as the carriage feeds along the computiiig wheels 51 in the totalizer 52, they will. be engaged and turned scria-fim by the master-wheel. 50. in order to cause the sari/"Kim engagement oi the computing wheels 01 with the master-wheel, the totalizer 52 l orms part of an adding can riage 53 connected by a bracl' t 5i to the typewriter carriage A, i trated in Fig. 2, there may be a plurality of totalizcers 52 on the adding carriage 52:3, aeapted to be adjustably positioned thereon.

In addition to the totalizers 52, there is provided a totalizer 55 adapted to effect cross-adding, and operated by a masterwheel 56 which is adapted to engage scriatim the computing wheels 57 in the totalizer To operate the master-wheel 56, there may be provided any usual or suitable gearing from the master-wheel 50, said gearing comprising, as herein illustrated, a horizontal shaft 58 and a vertical shaft 59 connected. by suitable gears 60. In order to enable the numbers computed in the totalizerq 52 to be cross-computed in the totalizer there is provided a separate or supplemental. adding carriage ($1 on which the totalizer is adapted to be adjustably mounted, said carriage til. comprising a rack (32 meshing with a pinion G3, which latter is adapted to he turned by the travel. of the typewriter carriage. To effect this turning, the pinion (53 fast on the front end of a shaft (Slhaving at its rear end a pinion 65 meshing with a segment (36 which is adjustably attached to a second segment 67, the latter constantly in mesh with the rack 68 which is adapted to be picked up intermittently by the typewriter carriage.

To effect this lIltQI'D'lllltGHl} picking up, the rack 68 has pivoted thereon a pick-up mem 69 having a notch 70 which may seat one of a plurality of suitable devices, as stops or dogs 71. These dogs are shown as mounted in a rack-bar 72 on the typewriter carriage, there being a separate dog 71 for substantially every lettcrspace travel of the typewriter carriage.

The dogs are normally held, in an ineffective position, as illustrated in Figs. 2 and 4:, and are adapted to be set from that position to the effective position shown in '13 1g. 3, in which position they stand, with their path intersecting a notch 70 on the pick-up member 69, with the result that as the typewriter carriage travels along, a cam 13 will depress the pick-up member (39 against the tension of the spring 7-]: when struck by the said dog 71. Continued travel of the typewriter carriage will bring the dog 71 over the notch 70 with the result that the spring T l will raise the pick-up member 69, so that the notch 70 seats itself on the said dog 71 and the carriage (31 travels along step by step with the type writer carriage. \Vhen the typewriter carriage has carried the secondary carriage (31 to the point at which the totalizer 55 clears the master-wheel 56, the pickup member 69 releases itself from the notch 70, because a pin 75 on the pick-up member (59 strikes a cam 76 adapted to depress the pick-up member (39 sutliciently to cause the cam 73 to be clear of the notch 70. This permits the usual spring 77 to return the secondary or sup ilemenlial carriage 61 to its normal position. T he spring Tel is not effective directly on the pick-up member (it), but lifts the pi -kup member through the lever 78 to which it is attached, said lever comprising a follower 79 which bears against the bottom surface 80 of the pick-up member (39. In order to keep the pick-up member (39 clear of the dogs while the secondary carriage, and con.- sequently the pick-up member, is returning to its normal position, there is provided a stop Sol effective on the lever 78 to limit its throw by the spring 74.

Both the steps 11 and the dogs Tl are adapted to be held in their set positions by means of detent balls 82 which are pressed by springs 83 into notches 84L formed in the dogs 71 and the stops 41.

Tu order to set the stops 451 there is provided a stop-setting arm or link 86 which is adapted to be depressed by drawing 'lorward a finger-piece 85, with the result that the stop-setting member will cause its set-- ting lug 87 to depress the stop l1 which is beneath itat the moment. ()n the release of the stop-setting member, the stop is retained in set position by the detent ball 82'. The connections between the finger-piece S5 and the member 86 include a link 88 pivotally attached to the linger-piece between the handle 89 thereof, and its pivot 90, said link extending rearwardly and slidable at its rear end in a plate 91 screwed to the frame of the machine and provided with an opening 92 which serves as a guide for the link 88. This link moves the stopsetting member because it rocks forwardly the lett-hand end 93 of a lever pivoted at 94, so that the right-hand end 95 of the lever will push rearwardly a rock arm 96, fast on a shaft 97, so that a second rock arm 98 on said shaft will pull down the stop-setting member 86 by engaging a heel. 99 at the lower end thereof.

The lever end 93 has a very small movement and may engage the link 88 by merely resting in a notch 100 therein which it fits fairly closely,'the right-handend 95 forming a sort of pin-and-slot connection with the rock arm 96. The shaft 97 may be journaled in ears 101 projecting from the usual ta-bulator-stop frame 102. To guide the stop-setting member 86 vertically, its upper end may ride in a fork formed 'by a pair of lugs 10% at the top of the tabulator-stop frame, and to prevent it from rocking backwardly, the member may be provided with a slot 101 by l which it straddles a fixed shaft 105. Theshaft 105 may include collars 105 to hold the member in the proper. vertical plane. In'order to hold the stopsetting member normally clear of the stops 11, it is provided with a spring 106 which draws on the end of the slot 1041 and may be anchored in any suitable place, as in one of the lugs or ears 103. The lever 93, 95 has its pivot 9 1 in a bracket 107 fast to thetypewriter frame.

If it is desired to set a dog 71, the fingerpiece 85 is moved rearwardly with the result that it rocks forwardly a dog-setting arm 108 pivoted at 109 on an car 110 projecting from the stop-frame. The connections for operating the dog-setting arm 108 include a pendant-link 111 connected by a pivot 112 to the forward end of thedownwardly-extending arm .113 of the setting arm 108, said pendant being provided with a heel 11:4: which is adapted to be struck by a third rock arm 115 on the shaft 97 when the finger-piecej85 is moved rearwardly. The two rock arms 98 and 115 may be formed as a single piece. The link 1,11 may normally .hold the dog-setting arm 108 in its rearward or ineffective position, and to accomplish this, the link is provided with a lug 110 to which is attached a spring 117 anchored in the tabulator frame and normally drawing the lug 1.16 upward. To guide the dog-setting arm 108, it may pass through an opening 118 in the tabulator? stop frame.

Since it is almostalways desirable to set a stop 11 whenever a dog 71 is set, there may be provided a connection wherebythe dogsetting arm will always operate the stopsetting arm 86. As herein disclosed, the connection includes a lug 119 on the link 111 which overlies a lug 120 on the stopsetting member 86. In order to set the stop .11 and the dog 71 at the proper letter-space, the setting members therefor are set near the center of the machine, and the fingerpiece 85., for convenience, is pla'ced at the end of the machine,-the lever 93, 95 and the shaft 97 serving to transmit motion from the end to the center of the machine.

I Forthe purpose of resetting the stops 11,

there isprovided a resetting slide 121 comprising diagonal, camshaped .openlngs 122 engaging screws or p ns 123'on the stopbar, so that mere pushing of the slide 121 endwisewill reset the stops. The dogs 71 are adapted to be resetby a similar slide 124chaving cam openings 125 engagingpins 1.26. As a furthermeans forsteadying the Variations maybe resorted to withinthe scope of the invention, andportions of the improvements may be used without others.
