To all whom it. may concern,"-

.Be it known that i, HARRY LANDsninnL, a citizen of the United States, residingat Cincinnati, in thecou'ntyo'f Hamilton and State of Ohio, have invented certain new and usegtul Improvements in Shuttle Carriage Mechanisni for Adding Machines, of Which the tollowingis a specification. I

The mechanism of the present. invention is' particularly designed for use in connection with adding machines Whi'chare intended to perm t the recording of itenis' n par-..

allel vertical coliimns, one of the columns, as for example the left hand column, containing-items WlllCll are ordinarily employed as identifying numbers or symbols,'and the fee '. listed, Without either adding-the item or ro-- tating the platen; lVith the parts-thuspoother I column containing amounts which are intended to be-added into the machine. Thus, for example, in using the machine for-the purpose of listing and recording the contents'of a number of freight cars, the, left hand column would be utilized,

for the purpose of listing the numbers of the cars While the right hand column fivould'be employed for recording the contents of each the total result. I

In a machine of this character, it isde'sirable to provide mechanism for automatically andaddin the items of contents to secure shifting the carriage transversely after each designating item has been listed, so that the corresponding amountmay be recorded and added in the same horizontal line; This necessitates the use of mechanism, actuated by the handle pull for shifting-the carriage to the left after a designating'iten'i has been sitioned to record anum'eral item, the mech anism is-entrained for the next succeeding handle pull to add in the item last recorded, to feed the platen, andito restore the platen to the right hand position prior to the next operation. It is 'evidentthat on the taking of a total or 'subtotah'only the'righthand c'olunni items will be included.

The inventiont'urther relates to thcmleans provided for disengaging the special shuttle.

. mechanism so as t-o .;r e'store the machine to its normal mode of operation The invention s an improvement over the one shown I and described-intheLandsiedel Patent h'o.

corresponding 1n the. patent mentioned, the means for disabling .the adding mechanism are controlled bythelateral movement of the paper carriage, While-in the construction of the present invention said -means are includedas a part of'thel device for shuttling" the paper carriage. e r I v The present invention also includes an improved method for. disabling the linespacing mechanism and other improvements Which will be apparent fro'm the fOllOWlDg ClQSCrip tionz I In the drawings:

In the drawings, the device has been ap-. plied to a Daltonadding machine Which in eludes a lateral stop carriage 1, type carit is not deemed necessary toenter into a detailed description thereof, save in so far as may be needtul to a full understanding of. the features comprising] the shuttling carriage --tion.

The platen 9 journalcd at its ends through end plates 11 which are secured to the ends of a traveling carriage frame l21vhich embraces and-is guided upon. a fixed frame 13'secui'ed beview: illustrating the Fig; is a fragmentary front view of the mechanism of the present invenis mounted upon a shaft 10 Fig. at is a plan. view of'tlie mechanism and tween the main side frames of the machine,

anti-triction devices beingprovided to r en'- able the platen carriage as a .Whole to travelbar 16, which is secured to and forms a part of the carriage frame 12, as shown in Fi g. 2. The'swinging arm 14 is pivoted at its rear end to the pivotpin 17,. and the rear end 18 of the arm is downturned through the flange 19 which carries the stud and is engaged by movement of the handle, so that one coma spring 20. Sufiicient clearance isaiforded between the arm 14 and the head of the stud 17 to permit the forward end of the arm 14 to be depressed against spring tension'suiiicientlyto disengage a selected notch for the purpose of readjusting the platen carriage to a different lateral position. This enables various portions of the paper carried by the platen to be brought to position to have columns of figures imprinted there-- It is obvious from the above description that asthe arm 14 is swung back and forth within the limits of its operation, it will shift the platen alternately to the right and left. The means provided for controlling the swinging movements of the arm 14, in conformity with the movements of the operating handle will now be described.

The arm 1% has pivoted thereto -a link 21, the outer end otwhich is pivoted eccentrically to a disk 22, which, during the operation of the machine, will be rotated intermittently in the same direction, being moved a half rotation with each return plate oscillation of the handle will serve to throw the arm, and with it the platen carriage to the left, and the next succeeding operation will throw the parts to the right.

The disk 22 is mounted upon a cross arm 23 rigidly mounted upon a vertical shaft 2 1 journaled at its upper end through a bracket 25, and has its lower end through a bracket The shaft near its lower end is provided with a small pinion 2? which meshes with a large gear 28 rotatably mounted upon a stud 29 upstanding from the bracket 26. The gear 28 carries a ratchet plate 30 provided with notches 31 adapted to 'co-act with a dog pivoted at its outer end to an arm 83, which latter at its inner end is pivoted upon a stud 29. The dog and arm are connected by means of a spring 3 1 which serves to hold the dog in spring contact with the edge of the ratchet plate. 3y swinging the outer end of the'arm back and forth, intermittent rotation will be imparted to the gear and parts associated thcrewitln The outer end of the arm 33 has mounted thereon a roller which is engaged by a.

notch 36 in the plate or, which plate is secured to the inner end of areciprocating slide bar 38. provided with guide slots .39 and 40 wh ch engage guide pins 41 and 42 respectively, as lndicated in Fig, 2.

Reciprocations are imparted to the slide bar 38 by means of a link 13 which is pivoted at its rear end to the slide bar 38 at. the point 4 1. The link atits forward end terminates in a hook 15 which engages a pin 16 carried by the upper arm of a bell crank lever 1 7 which is pivoted to the stud 18 upon the side frame of the machine.

The lower arm of the bell-crank lever is engaged by a link it) which at its lower end is pivoted to a "segn'ient carried by the main handle control shaft 6, so that with each -forward pull of the handle, the slide bar 38 will be moved rcarwardly and the dog retracted in position to engage the next succeeding. notch on'the ratchet plate. lVith m the parts thus adjusted, the return movement of the handle will actuate the gearingand impart a-swinging movement to the arm which controls the shuttling of the platen carriage.

lVhen it is'desired to normalize the-operation of the machine, by disabling the shuttling mechanism. this result is secured by the action of a. disablinglevcr 51 which is iub crumcd upon a cross bar 52. The rear end of the disabling lever lies under a stud 53 inwardly extending from the hooked'link 43, and the forward end 5-1: of the. disabling lever is liiit'urcated to receive the inturned end 55 of a beltcrank lever 56 which. is pivoted at its elbow to a stud 57 carried by a bracket 58 secured to the front wall of the machine, as shown in Figs. 2 and 3. The bell crank lever is adapted to be swung back and forth by means ct an outwardlj, protruding finger piece 59 which engages a pivoted spring controlled detent ($0 contigured-in its upper edge to hold the bell crank lever in either position of. adjustnient. By a lateral movement oi the linger piece 52), the outer end oi? the bell crank will be raised and lowered, thereby in'ipar'ting a like movc ment to the forward end otthe disabling lVhen the forward end of the dis- The mechanism for disabling the line spacing mechanism of the paper carriage will now be described. The lower end of the vertical shaft 24 carries a cam plate 1 hav ing a fiat side and an elevated side. Associated with the cam is roller (3-3 mounted upon the rear'cnd of a slide bar (3 provided on its upper edge with a cain'elevation (H. This cam elevation (3-1 co-acls with a roller (35 mounted upon. a swinging bracket 66 freely pivoted upon the cross bar 52, which bracket carries an arm 67. The forward movements of the slide bar 63 will serve to thus elevate the arm 67, and this arm when elevated will engage with an arm 68 mounted,

upon a squared line spacing shaft 69, which shaft also carries a finger 70 having a pawl 71 pivoted thereto, which pawl co-acts with the usual ratchet wheel 72. These parts are actuated by a ,spring73 when the operating lever ispulled forward and restored to their normal positions by-a positive cam action,

' (not shown) on the return stroke in a manner common in the-construction of adding machines. VVhen,.however, the arm 67 1s lifted, it will-be noted that the arm 68 will be blocked. against itsno'rinal forward. movemerit,- so that. the line spacing mechanism will be disabled, and since these movements arecontro-lled by means of the cam 6-1 on the verticalshaft 24:, and since this shaft makes a half rotation with each h'andle reciprocation,.it is evident that the line spacing mechanism will be disabled'on alternate operations of-the handle, and that line spacing will occur only when the platen carriage is ,in its left hand positiomthat is to say, after a numerical item has been introduced into the righthand column.

Means for disabling'the adding mechanism during the printing of an item in the left hand column will now be described. lt-

is essential that the line spacing.mechanism and the adding mechanism be hotlrdisabled at the same time, and the slide bar 63 is likewisc relied upon to effect a disabling of the adding mechanism as well as the line spacing mechanism. 1 This bar is provided on its under edge with a depending linger 74; which engages a stud 75 on the upper arm of a bell crank lever 7 6 which is pivoted on I a cross rod 77. The lower arm of the'bell crank lever is provided with a stud 7 8 which is adapted to control the movements of a wipe pawl 79 which is pivotedto the usual v segment 50 carried by the handle operated main shaft 6, a spring 81 being provided to normally hold the rear or acting end of the wipe pawl in an elevated position. The wipe pawl co-acts with the usualmechanism provided for lifting the bank of adding wheels-intoinesh with the usual adding racks 3 on the return stroke thereof. This mecha nisin, is old and comprises a 'cam 82 and a;

plate 83 provided witli'studs' 84 The cam 82 is rigid on the shaft 85 and when the latter is rotated by engagement of the rear end of the wipe pawl-79 with one of the studs 84, the cam will berotated and the addingwheels lifted into meshwith the racks in the usual HllIHDGYGXCQPt when the wipe pawl is thrown out of commission by the, disabling mechanism herein specially provided.

lVith the stud 78, in the depressed posiwhen the slide bar 63 is moved to itsrear motion, as indicated in 2.

tion shown Fig. 1, theforward end of the wipe pawl, as it is swung forwardly with the forward pull ofthe handle, will engage and ride over the stud thereby throwing down the rear end of the wipe pawl to an inoperative position, so that upon the return movementof the handle and the segment no actuation of the. addingwheel lifting devices willloe effected. On the contrary,

position, and the stud 78 is lifted through the pull of the spring 86, the wipe pawl will occupy its normal position and upon its return. stroke will engage the stud 84: on the addmg wheel actuating series, there by permitting a movement,- upon the back order to readjust the platen carriage to a different position laterally for the. purpose of recording numbers upon a different lateral section of the paper. Pivoted tc the upper. section of the fixed ball rail frame A .13 on the rear sidethereof is a tabulator latch 8 provided' with an i'ipstanding tongue 88 whicn normally extends upwardlyandohliqucly therefrom in' a rearward .di-

The tonue occupies a position in roxib i mate relation to .a pair of spaced transversely extending bars QOwhich are connected their ends between a pair of end plates 91 pivotally niounted between the carriage frames 11, one of said endplateslceing provided with a handle 92, so that the two bars may be rocked 'ortilted in unison. These bars normally present their edges in parallel relation to the slotted tongue 88, which edges are PIOYl'ClGCl at closely spaced intervals with notches 93. Corresponding notches in the upper and lower plates furnish points of engagement for a plurality of yoke plates 94 (see Fig. 8).

The lateral edges 9430f the tabulator latch tongue 88 are bent back to present a beveled front acting surface, and the latch as-a whole. is pivetally mounted for a rocking movement on the screw studs 96 which-con 5 meet the latch with a lug 9 7 011 the rear upper rail of the fixed ball'casting. To bet- .ter maintain the latch in pos tion, a pair of end tongues 98 lying within the slots 99 in the lug are provided and a spring 100 is connected at itsouter end to a tongue 101 and'ati .its inner end to a fixed plate 102, tlierebyserving to normally hold the: latch forwardly, in which position the tongue 88 will. engage with. the edge of one of the yoke plates 94 when brought into register therewith.

engag'e1ne11t of the shuttling bar can be Integral with the latch is'a' rearwardly extending detent 103 which occupies a position immediately above the pivot which connects the link 21 with the shuttling arm 14:, which latter, as previously explained, is loosely pivoted on the stud 17, so that its end may be slightly depressed. The arrangement is such that when'the finger lever 92 is-depressed the notched bars are rocked or tilted causing the rear lower corner of the yoke plate 94: to bear against the latch tongue 88 in such a way to rock the latch and depress the detent 108 which bears down onthe shuttling arm and permits a disengagement thereof from the notch in the tabulator bar. r

The yokes 94 are so located as to occupy positions .at or near the terminal points of movement of the shuttling arm, so that when the latter is brought to rest in' eitherof its terminal positions, it will lie in proximate relation to the detent 103, .so th'ata dismade and a repositioning of the platen carriage effected.

the link 21' with the disk sion of numerous notches in the compamon bars 90, permit the yoke plates to be located at positions corresponding to the movements of the shuttling bar.

In operation, after an indicating'number has been set up in the usual stop carriage of 'themachine, with the platen, in its right hand position, and with the paper disposed to receive an impression in the left hand or non-adding column, the handle will be pulled.

andthe figures printed .in the usual'manner. -With the parts adjusted forthis operation,

the adding mechanism and the line spacing mechanism will both be disabled, so that the only operation special to the present invention, which takes place "on the return movement of the handle will be the shuttling of the carriage tothe left to bring the paper into position to receive a numerical item in the right hand column and on the same hori- Zontal line with the designating item last iniprinted. After the numerical item has been set up, the handle is again pu'lled',.but onthis occasion, the parts are in such position that on the return stroke of the handle the adding wheels willbe in mesh with the racks, so that the item will be accumulated, and simultaneously the line spacing mechanism will operate to turn the platen sufficiently to line space the paper in preparation for the imprinting of another designating item in the left hand column.

By adjusting the stud 59, all of the mechanism, special to the present invention. is disentrained from the handle shaft, so that the machine as a whole may readily be re stored to operation as a regular adding nia forward I The shuttling The throw of the shuttling arm can be amplified or decreased by ra-- dially changing thepoint of attachment of and the provi chine, in which case, of cause, the platen will operate continuously in one position, and the line spacing mechanism will operate with each oscillation of the handle instead of with alternate oscillations as in the case when the shuttling devices are in service. I features ot-this invention are of such a nature that they can be readily appliedto adding machines'of standard construction without-in any way changing or modifying the general structure of the machine as a whole, since these devices. are fitted to occupy spacenot otherwise occupied and are adapted to function without interference with thememainmg mechanisms.
