lan section of aI I; have herein shown the invention as embodied in a machine capable of dealing with both decimals and English currency, but it will be evident that certain features of the invention may be employed in a machine adipted to add or record English currency, on y.

For convenience in affording an understanding of the invention I shall describe the same as applied to or embodied in the ten-key adding and listing machine disclosed in Patent No. 1,198,487 granted September 19, 1916, to Rockford Milling Machine Companynpon an application filed by Gustaf David Sundstrand, but I would have it understood that the present invention is not limited to machines of the general character illustrated in said patent. Without, therefore, intending to limit the invention to machines of any particular type or charact-er, I' have herein illustrated a machine comprising a platen 2 and a plurality of type bars. In the present instance there are ten type bars, but the number may be greater or less.

The type bar A (Figs. 1, 4 and 9) at the extreme right carries at its up er end a single type-carrying plunger 9 adapted to print a character which, when printed in red, denotes that the machine has been cleared, and, when printed in black, indicates that the item o posite which it apears has not been ad ed. The type bar A as no movement.

The second type bar from the right is marked Ax irl-Figs. 1a, 2, L@and 9 and carries twelve type plungers 9. The uppermost plunger is adapted to print a characterY (hereln the letter D) to indicate that the machine is jset to add and rint decimals. The remaining plungers on t e type-bar Ax are adapted `to print from one to eleven, respectively. The type-bar Ax is normally in position to print the character D,

The remaining type-bars are designated A1', A2, A3, A, A, A, A7 and A8 in the drawings, and each is provided with ten type-carrying plungers 9 adapted to print from naught to nine, respectively. The type-bars A1 to A8, inclusive, are normally in osition to rint ciphers.

he means or vertically moving the bars Ax to A8, inclusive, from the normal or initial position to any other selected position lll) and back again may be of any preferred character, that herein shown being generally similar to the mechanism disclosed in the before-mentioned Patent No. 1,198,487 and identical-with the mechanism shown in my copending application Serial No. 409,- 778, filed September 13, 1920 (now Patent No. 1,583,102, dated May 4, 1926). The type-bar-moving means need not, therefore, be described herein further than to say that it comprises a handle 27 and connections to the type-bars including springs 14. When the operator pulls the handle 27 forward movement is yieldingly transmitted through the springs 14 to such of the type bars A* to A8, inclusive, as are are liberty to rise. When the operator releases the handle on the completion of the forward stroke, means of any ordinary or suitable character returns thc handle to the normal position shown in dotted lines in Fig. 1.

The means for limiting the extent to which the type-bars A* to A8, inclusive, may rise and thus to determine which numerals shall be bi'ought to the printing position may be of any preferred character. That herein shown is generally like the setting-up mechanism of Patent No. 1,198,487 and coniprises a group of stops 42, each stop being .iorizontally slidable 1n a forward and back direction in a stationary guide frame 43. When moved rearwardly from the position shown in Fig. 1 the stops are in the path of movement of devices carried by the typebars Ax 'to A8, inclusive, and thereby limit the upward movement ofsaid bars. These devices consist of arms 45 ivoted to the lower portions of the typears, and pins 46 havin openings through which the arms 45 exten The pins 46 are guided for vertical movement in a slide 47 which is mounted on a stationary guide rod 48 extending transversely of the machine. The guide rod 48 is so positioned with res ect to the guide frame 43 that the slide 4 is movable to carry the piiis-46 from their normal or initial position at the left-handY side of the group of stops 42 into vertical alinenient with the columns of stops. There are eleven stops in each column.

When the machine is set for adding and printing decimals, those type-bars A* to A, inclusive, which are not needed in accumulating or printing a given item are prevented from rising when the handle 27 is pulled forward by a detent plate 48a (Fig. 13) guided to move in a horizontal plane, said plate being connected through a bar 48b to a frame 48 (Figs. 1 and 4). The frame 48n is mounted to swing on the axis of a rod 5 and is normally impelled forward by springs (not herein shown, but disclosed in said Patent No. 1,198,487).

The means for projecting the stops 42 into the vertical 'path of movement of the aeaasao pins 46 com rises a plurality of number eys 49 whic are numbered from 0 to 9, as indicated in Fig. 3. The operating eonnections extendin from the eys 49 may be of any desired:7 nature, as, for example, that shown in my said Patent No. 1,583,102. The present drawings disclose operating connections like those illustrated and described in m said patent and hence need not be describedy herein in detail. Suice it to say that each of theA keys 49 is connected to an arm 54 of a lever pivoted on the axis 55 (Fig. 4.) A contractile spring.56 (Fi 18) connected to the arm 57 of each o4 said levers serves to restore the corresponding key 49to its normal position after a depression thereof. Two levers 58 and 58 Figs. 4 and 17) are pivoted on the axis 55. "o the arms 58Il of said levers is fixed a vertical universal rod 59. A contractile spring 61 normally holds the universal rod 59 in-contact with arms 54l which are rigid with the arms 54.

A number key 49a (Figs. 2 and 3) bearing the number 10 is attached to a stein 49X which is mounted for vertical movement and which is impelled upwardly to its normal position by an expansion spring 50". A stud 5lx on the ke -stem 49x lies in contact with a cam sur ace 52* on an arm 53x which is pivoted on' the center 53. The free end of the arm 53x bears against the arm 54x (Fig. 16) of a lever similarto the levers having the arms 54. A contractile spring 56x (Fig. 16) connected to the arm 57x serves to restore the arm 54x and the arm 53x to normal position. The key 49a is .used in adding and printing 10d.

A number key 49" (Figs. 2 and 3) bearing the number 11 is afiixed to a stem 4,9y which is guided for approximately vertical movement. The lower endv of the key-stem 49y is pivoted to one arm of a lever 50y which is pivoted on the center 53". To the other arm of the lever 50y is connected a contractile spring 5P that serves to impel the key 49b upwardly to normal position, s aid position being determined by Contact of a lug 52y ou the lever 50y with a stop pin 53Y. '0n the lever 50y is a stud 54y (Fig. 17) that lies in front of a rod 55Y fixed to the levers 58 and 58'. It will be seen that when the key 49" is depressed the frame compose( of the levers 58 and 58 and the rods 55y and 59 will be swung in one direction, and that when the key 49b is released the spring 61 (Fig. 4) will restore said frame to normal position. The key 49b is employed when adding and printing an item containing 11d.

As shown in Fig. 3, the number keys and the feature, keys (i. e., the Non-print, Error, Repeat, Non-add and Total keys) are compactly grouped, the ten key 49 being located at the right of and adjacent to the nine key, and the eleven key 49" being located directly behind the ten key.

A 11i-cra 62 Figs. 4 and 13) is pivoted' on the center in icated at 63,' and carries a post 64 in which are slidably supported the rear ends of twelve ushpins (Fig. 2)'. The forward end el) the uppermost push pin is pivoted to the lever 58 and conse- Tiently will be moved when the key 49" is t epr'essed. The next lower push pin is pivoted to the al'm 54x and therefore will be moved when the key 49 is depressed, The

'remaining ten push pins are pivoted to the arms 54 and hence will be moved when the respective keys 49 are depressed. The push pins are arranged in a vertical row or column and all except' the uppermostpush pin is adapted to push the stops 42 outof the position ,shown in Fig. 1 and into the path of the upward movement of the pins 46.

The slide 47 is caused to move in unison.

Ywith the bracket 62 by means of a pin 66 (Fig. 13) associated with said bracket and` lying within the bifurcation of a lug 67 on the slide. 'As the operator sets up an item of English money on the keyboard, the slide 47 and the bracket 62 are moved from one vertical row of stops 42 to the next adjacent row as each number key 49, 49 or 49" is depressed and restored. The series of push pins 65 normally stands in front of the vertical row of stops which is farthest to the left, and is moved to successive vertical rows of stops as the setting up of the item progresses. y The series of pins 46 is moved from left to right, step by step. In adding and printing such an item as ten pounds, two shillings and ten pence. the item` would be printed as indicated in Fig. 8, where it will be seen that a space equivalent to that Aused for onenumerieal order is employed for pence, and that a space equivalent to that used for two numerical orders 1s reserved for shillings. Consequently, the series of pins 46 is moved from left to right one step for each numerical order necessary in' setting up pounds. two stepjr in setting up` any quantity of shillings, and one step in setting up any quantity of pence, thereby bringing the necessary number of pms 46 into vertical alinement with the stops 42 that have been set by the push pins 65.

In adding and printingl decimal currency the second typebar from the right (the type bar Ax) is used only to print the signal or distinguishing character D arid is not ern ployed in adding or recording digits. Therefore when adding and printing decimal currency it is necessary to impart to the slide 47 an extrav movement or step 1n order to carry the pin 46 for the typeibar Ax out of alinement with any of the set stops 42 and to carry lthe pins 46 for the type bars A1 to A8 into vertical allnement "which is pivoted on :1 vertical axis 351 on the bracket 62. The pln 66 normally stands adjacent to a lug 352 on the bracket 62. The

forward end of the lever 35() is held in contact with an adjusting member 353 by means of a torsion spring 354. The adjustmg member is generally:truste-conical in form and is vertically slidable upon a stud 355. An arm 356 engaging a grooved por- Ation of the adjusting member 353 is fixed upon a rock shaft 357. Rigidly attached to the shaft 357 is an arm 358 (Figs. 5 and 14) carrying a pin 359. A reciprocatory bar 360 (Figs. 5 and 14) is notched to provide a shoulder 361 adapted to engage the pin 359 and swing the arm 358 rearwardly to lower the adjusting member 353 and thus allow the torsion spring 354 to move the slide 47 one step to the right with relation to the bracket 62. The notch alluded to also providesa shoulder 362 adapted to engage the pin 359l and push the arm 358 for- I4svardly to r'aise the adjusting member 353 and thereby restore the slide '47 to normal relation to the bracket 62. The forward end of the bar 360 is arranged to be held up in engagement with the pin 859 by a contractile spring 363 (Fig. 5) when decimals are being added or printed. The rear end of the bar 36() ispivoted to a lever 76 fully described in my said Patent No. 1,583.102. During the early part of the forward stroke of the handle 27 the lever 7 6 is moved to draw' the bar 36() rearwardly. During the latter portion of the return stroke of the handle 2 7 said lever is moved to return the bar 360 to its initial or forward position.

lVhen English currency is being added or printed the bar 360 is held down far enough so that the shoulder 361 cannot engage the pin 359, but not too low to prevent ger piece is enlarged to fit upon the stud 367` and the linger piece engages said stud with sufficient spring pressure to hold the linger piece in place while allowing the finger piece to be pulled out whgn the casing 274 is to be removed.

The lever 364 carries a pin 368 that overlies the bar 360. lVhen the finger piece 365 is shifted to the position show n in Fig.. 14 (which is the position for adding or printing English money), the pin 368 holds the bar 360 in such position that the shoulder 361 cannot move the arm 358. The lever 364 is yieldingly locked in either otvlts two positions by a detent lever 369 (141g. 15) which is pivoted at 370 and has a V-shaped tooth 371 that is pressed against a pin 372 on the lever 361 by a contractile spring 373. The pressure of the tooth 371 against the pin 372 insures completion of movement of the lever 364 in either direction and holds the lever in adjusted position. 374 and 375 are stop pins on the lever 364 which engage parts of the machine frame to limit oscillation of said lever.

.-i.-detent lever` 376 (Fig. 14) pivoted at 370 has a notch to receive a pin 377 on the arm 358. 378 is a contractile spring that presses the dctent level' 376 against the pin 377. Said detent'lever serves to prevent accidental relative movement between the slide 47 and the bracket 62 when the machine is set for adding or printing English currency.

'l`he means whereby the handle 27 may cause. the additional or extra. relative movement between the group of stops 42 and the group of pins 46 may be termed set-up-adjusting means.

ln case the operator should shit't the setting lever to the English currency position while the handle 27 is in its forward position, the

shoulder 362 on the bar 360 will return the adjusting` member to its proper upper position during the return stroke of the handle.

A special stop is provided to hold down the type bar AX when adding or printing a decimal item or total. because the extra step imparted tothe slide 47 by the torison :p1-ing 354 carries the pin 46 of said type bar out of register with any of the set stops 42. The special sto) just referred to conssts ot a lug 379 `ig. 9) formed upon a U-shape sheet metal member 380 which is virtually a. lever pivoted to the framework by means ot' two screws 381. A headed stud 382 limits movementof said lever in one direction. A spring 383 tends to hold the lever 380 in the position shown in full lines in Fig. 8, wherein the lug 379 lies in the path of upward movement ofthe tail 384 ot' the type bar AX and thus prevents any character but the signal D from being printed by the type bar A".

The means for moving the lever 380 to carry the lug 379 out of the path of movement of the type bar Ax when English money is to be added or printed comprises a rod 385 (Figs. 9 and 15) pivoted at its forward end to the setting lever 364 and slidably supported'at its rear end to bear aga-inst the lever 380. When the setting lever 364 is moved to the position for adding or n'inting EnglishI currency, the rod 385 pushes the lower part of the lever 380 rearwardly far enough to place the lug 379 out of the way of the tail 384. The type bar A* is then tree to rise to the extent permitted by a stop 42.

The slide. 47 and the bracket 62 may be moved to the right by any preferred means, as, for example, a. contractile spring 68, the action ot' the spring being controlled by an cscapcment as described in said Patents Nos. 1,198,487 and 1,583,102, the cscapement being operated by the uppermost push pin 65. As said push pin is pivoted to the lever 58 and said lever carries the universal rod 59, the top puslrpin will be moved whenever any one of the keys 49, 49 and 49b is depressed.

rlhe slide 48 and the bracket 62 may be moved to the left into the initial position by any suitable means, as, for example, that disclosed in said Patents Nos. 1,198,487 and 1,583,102, the lever 76 forming a part of said restoring means.

The means for driving the type-carrying plungers into contact with the inkingribbon may be of any prefrred construction, that herein shown being generally similar to the hammer mechanism of the well-known Sandstrand adding machine. The means for printinoc the Clear and Non-add signal is identical with that of the Sandstrand machine, and hence its construction and operation need not be here disclosed in detail. lt is suflicient to say that when the operator depresr-es the total key 177 or the non-add key 152 and pulls the handle -27, a bumper 101 is raised into position to transmit the blow of the hammer 100 to the typecarrying plunger 9. the ribbon also being operated so that the impression shall be made in one color opposite each non-added item andl in another color opposite each final tota 4 .The hammer mechanism associated with each of the type-bars Ax to A8, inclusive, comprises a hammer 386 pivoted on the axis 387 and impelled by a contractile spring 388 to strike the type-carrying plunger that is positioned at the printing line. The hammers 386 are cocked and released by means comprising two levers 389 (Fig. 7). The levers 389 are pivoted on the axis 387. A rock shaft or pivot 390 (Fig. 1) is mounted in the levers 389. Pivoted on the shaft 390 is a frame 391 consisting of a piece of sheet metal bent to form two end pieces 392 and a connecting web 393, and two universal rods 394 and 395 are carried by the end pieces 392. The rod 394 is adapted to engage hooks 396 (Fig. l) on the hammers 386 to draw forward orcock the hammers. A contractile spring 397 (Fig. 5) connected to the rod 395 tends to swing the frame 391 Sli bars which are not concerned in the printing of the given item or total are, however, restrained by latches 398 which are pivoted on the shaft 390 and are adaptedi to engage shoulders 399 (Fig. 5) on the hammers. The latches 398 are disengaged from those hammers which are needed to print the item or total by means of controlling levers 400 pivoted on the axis 401. The inner or rear end of each lever 400 is adapted to enter a notch 402 (Fi s. v1, 2 and 8) formed in its respective type ar. The other end of the lever 400 is normally held in contact with the rod 395 by a contractile spring 403. In the forward portion of the lever 400 is formed a flaring noto/h or throatway 404 in Which movesa stud 405 (Fig. 1) on the latch 398 located at the right ot' the lever. (The .notch 404 in the extreme right-hand lever 400 has no function, as no latch is associated with that lever.) The lower wall of the notch 404 constitutes a cam surface 406 (Fig. 5,) which serves to insure that the *A latch 398 shall swing forward out ot en-y ffagement with the shoulder 399 duringthe orward and downward movement of the frame 391 it gravity docs not eii'cct such dienga'gement.

When the handle 27 is pulled forward to cause the printing of an item or a total, the levers 389 swing down, thereby lowering the universal rod 395, the springs 403 drawing the forward ends of the levers 400 down as said rod descends. Before the forward ends of the levers 400 have completed' their downward movement they come in contact with the pivot shaft 390, which' restrains said springs until said pivot shaft has passed below the forward ends of the levers, whereupon the forward ends of said levers complete their downward movement. As shown in Figs. 1 and 2, the inner ends of the levers 400 normally stand a little ldistance away from the type bars. are needed to print the item or total begin to rise before thev inner ends of the associated levers 400 can enter the notches 402 of said type bars; consequently the inner ends of said levers stop 'against the forward edges of the raised type bars, so that the continuing downward movement of the frame 391Y causes the studs 405 of the latches engage the cam surfaces 406 and be thereby The type bars which moved to release the corresponding hammers.

The levers 400 which are associated with the type bars that do notparticipate in the printing operation engage the notches g correspond to the type bars that did not rise.

When' the handle 27 commences its return -stroke,.means such asthat disclosed in said Patent No. 1,455,555 causes the frame 391 to tilt upon its axis 390, thereby disengaging the rod 394 from the hooks 396 of all of the hammers. Those hammers that correspond to the type bars that remained in the initial position are, however, restrained by the corresponding latches 398. Y l

As hereinbefore stated, the type bars A to A8, inclusive, are initially in position to print ciphers, and therefore when a cipher is to be printed there is no upward movement to be utilized in causing the corresponding hammers to print. Other means is accordingly provided to eii'ect the .release oi the hammers thatv are toprint ciphers. This means consists `of a lug 407 (Figs. 5 and 7) on each otthe controlling levers 400 corresponding to the type bars A to A8, inclusive, each of said lugs underlying a lug 408 on the lever 400 next to the right (with theexception that there is no lug on the lever 400 that corresponds to the type bar AX). Vhen any lever 400 comes in contact with 'a raised type bar, t-he lug 407 on said lever supports all the levers 400 at the right of said lug (with the exception just noted).

As previously stated, the machine herein disclosed, when printing decimals, is arranged to print the letter D opposite each item and total. Said distinguishing character is printed by the uppermost plunger 9 on the type bar AY, hence there is no u ward movement of said type bar to Ee availed of to effect actuation of the corresponding hammer. I therefore provide special means to eii'ect the desired result, whichmea'ns will now be described.

A sheet-metal member 409 (Figs. 1, 2, 4, 5, 6 and 7), which is virtually a lever, is pivoted on the axis 410 andv is provided with a finger 411 (Fig. 7) adapted to lie in the pat-h of the downward movement of a stud 412 attached to the controlling lever 400 for the type bar A. The lever 409 is connected through the medium of a link 413 (Fig. 5) to the stud 367 on the setting lever 364. inasmuch as the movement of the lever 364 is ,greater than is needed for moving the lever 409, the link 413 is formed with a loop 414 within which the stud 367 may move. A contractile spring 415 (Fig. 6)

tends to move the lever 409 in the direction to dispose the linger 411 out of the path of movement of the stud 412.

When the setting lever 364 is in the decimal position, and the handle 27 is ulled, the finger 411 holds the lever 400 or the type bar Ax in the same position .that it would occupy if the inner end of said lever 400 were in engagement with a ralsed type bar; consequent y the hammer for said type bar A will be caused to print the signal l).

The lever at the extreme right of the group of levers 400 serves only as a guide to hold the latch 398 of the hammer for the type bar Ax against lateral displacement. As a matter of convenience, said lever 400 and the one next to it may be rigidly secured to ether by means of the stud 412.

hile various forms of adding mechanism may be employed. that herein shown comprises a series of adding pinions (see Fig. 12) rotatably mounted upon a shaft 126 which 1s carried by a frame 127 (lfig. 1) pivoted at 128. The pinions (of which there is one for each of the type-bars Ax to A8, inclusive) are adapted to mesh with racks 129 Jformed in said ty e-bars. The nion 1.25K that meshes wit 1 the rack of t e pence type-bar A* has twelve teeth. The pnions 125 that mesh with. the racks of the type-bars A1 to As, inclusive, each have twenty teeth.

When an item is to be added the frame 127 is thrown forward to disengage the pinions from the racks before the type bars are raised; and said frame is swung rearwardly just before the type bars are moved down-- wardly. Addition therefore occurs in the downward stroke of the type bars, the eX- tent oi' therotation of the pinions depending, of course, upon the extent of movement of said bars. Theframe 127 is swun to carry the pinions into and out of mes with the racks by any suitable means, as, for example, that fully disclosed in the before-mentioned Patent No. 1,198,487.

lhile any preferred means for transferring or carrying from one numerical order to the next higher order may be used, that herein shown is generally similar to the carrying mechanism shown in said Patent No. 1,198,487. r1`he carrying mechanism associated with the type bars As to A, inclusive, is substantially identical with that illustrated and described in said patent.

The extent of the downward movement of the type bars A1 to A8, inclusive, is limited .(except in the carrying operation)1by contact of the shoulder 157 (Fig. 8) on said type bars with stop lugs 158. When?- an amount is to' be carried from one order to the next higher order, the stop lug 158 for the type bar belonging to such higher order is withdrawn, thereby allowing that type bar to descend to the limit of its downward movement, The extent of such descent is .just suicient to turnl the adding pinion for that type bai' through the distance of one tooth. Each sto lug is formed on a slide 159 which is guidedj for horizontal reciprocation. To each slide 159 is pivoted a dog 160 ('Figs. 1 and 2) having a tooth 161 adapted to lie in frontof afstationary locking plate 162. A spring 163 tends to hold the tooth 161 in engagement with the plate 162 and also tends to pull the dog 160 and the slide159 rearwardly. When the tooth 161 is in engagement with the front edge of the plate 162, the stop lug 158 is in position to limit the downward movement ot' the corresponding type bar. When the tooth 161 is disengaged from the edge of the plate, the spring 163 pulls the dog and the 'slide back so that tlie stop lug 158 is out of the path of movement of the typebar.

In the ease of the type bars A and A3 to A8, inclusive, the means for disengaging the tooth 161 from the plate 162 consists of two diametrically opposite lu s fixed to the pinion of the next lower ori er, as disclosed in said Patent No. 1,198,487. (ln this embodiment of the invention, two lugs are provided because each pinion yhas twenty teeth.) When the amount accumulated on a pinion reaches 9, continued rotation of the inion as the rack descends brings one of t e aforesaid lues against the end of the dog 160, thereby depressing the dog until the tooth 161 is below the front edge of the plate 162, whereupon the spring 163 pulls the dog and the slide 159 rearwardly until the lug.158 stops against the plate 162. The lug 158 is then out of the path of the rack of the next higher order, and the latter therefore moves down far enough to turn its intermeshing pinion through the distance of one `toth.

The carrying-mechanism associated with the pence type bar A* also is identical in substance with that disclosed in said Patent No. 1,198,487, the pinion 125x (Fig. 2) having twelve teeth and having attached to one side a lug 164 adapted when the pinion makes a complete revolution to depress the dog 160 and thus release the unit-Shilling type bar Atto downward movement equal to the distance of one tooth, thereby turning the pinion 125 for said type'bar A1 through the distance of one tooth, as explained in said Patent No. 1,198,487.

lhe carrying mechanism associated with thej'iinit-shilling type bar A1 for moving tlpemtenslshilling type bar A2 is like that described in said Patent No. 1,198,487.

Since there are twenty shillings in a pound sterling, the carrying mechanism for transmitting movement from the tens-Shilling type bar A to the unit-pound type bar A3 operates whenever two tens have been accumulated on the pinion 125 for the tens- Shilling type bar A2. Said pinion (which has twenty' teeth) has attached to one ofl its Sides ten tripping lugs (see Fig. 10). The two diametrically'-opposite lugs are somewhat longer than the others and are desig- When English money is being registered the dog 160 occupies a position farther forward so as to be operated by each of the lugs, and consequently is operated once for every two teeth of the tens-Shilling pinion 1211*. The means for determining the position of the dog 160 comprises a rock shaft 416 (Figs. 1 and 11), to one end of which is fixed an x11-111417. Said arm is arranged to be swung forward by the setting lever 364 through the medium of a. link 418 SF ig.

Inasmuch as the movement of the ever 864 is Agreater than the arm 416 requires, the link 418 has a loop 419 at its rear end in which the headed stud 420 on the arm 416 may slide. -A contractile spring 421 swings the arm 417 rearwardly when -the setting lever 364 is swung back to the position for adding or printing English'currency. The shaft 416 is provided with an eccentric or crank portion 422 (Figsl and 11) which engages a slotted portion of a block 423 that rests on the plate 162. A

, leaf spring 424 engaging the rear portion ci' said block holds that end of the block down on the plate162. On the forward end of the block 423 is a lug 425 that lies in a recess 426 (Fig. 11a) in the front edge of the plate 162.

1When English money is being added, the block 423 is in its down position, wherein the lug 425 fills the recess 426, the front edge of said lug being then flush with the front edge of the plate 162. The block 423 is, in the vertical plane of the transfer dog 160". -When the block 423 is down (as in Fig. 10) the tooth 161 of the dog 160a engages the front edge of theV lug 425, and therefore said dog is in position to be engaged by each of the lugs 164 and 164", as a result of which the unit-pound type bar A3 is given a carrying movement whenever two tens have been: accumulated on thel pinion 125n for the tens-shillingtype bar A2.

Vhen decimals are to be added, the operation` of the setting lever 364 causes the block 423 to be 4raised high enough so that the lug 425 is above the path of movement ofthe tooth 161, and consequently the spring 163 holds the dog 160,'w1th its tooth 161 in'contact with the rear vend wall of the recess 426, in which position the front end of the doo 160R is out of the orbit of the lugs 164b but within reach of the lugs 164x. Accordingly the type bar As will be given a carrying movement whenever ten has been accumulated on the pinion 125B 4for the typev bar A2. It will vbe seen that rthe lug 425 and the rear end wall of the recess 426 constitutes two alined stops for the transfer dog 16o,

After each carrying operation, the slide 1 59 is restored to its normal (for-ward) position by a universal rod 165 (Fig. 1) as explained in said Sandstrand Patent No. 1,198,487.

In the present embodiment of the invention, a special stop is necessary to limit up- -ward movement of the tens-Shilling type bar A2 when adding or printing an item of English currency. The pinion 125 is thrown out of mesh with said type bar before the type bar rises in printing an item; and consequently, in the absence of means to prevent such result, if through mistake twenty or more shillings were set up as such on the keyboard, the type bar A2` would rise to the extent permitted by the corresponding stop 42 and hence incorrect results would be obtained. ver 380 (Fig. 9) a shoulder or projection 427 which stands in the path of upward movement of a stud 428 on the tail 429 of. the type bar A2 (as shown in dotted lines 1n 8) when the setting lever 364 is in position for printing or adding English currency and thus prevents the rise Aoitv the type bar A2 above the position for printing $6177.

The mechanisms whereby a subtotal or a iinal total may be printed may be of any preferred character, as, for example, the mechanisms disclosed in Patent No. 1,198,487 or in Patent No. 1,588,102.

It is believed that the operation of the machine will be clear from the foregoing description, particularly when reference is made to the sample of work shown in Fig. 8". The fact that clear signals, subtotals and final totals are printed in a distinctive colorhas been indicated in Fig. 8a by representing such signals and totals in dotted lines.

The setting lever 364 being in the decimal position, operation of the handle .27 will result in the printing of the character D, as the finger 411 is in position to cause actuation of the hammer for the ty e bar A* every time the handle is operate whether in taking blank or spacing strokes or in printing an item, a subtotal or a final total. When the machine is clear, operation of the handle effects printing of the character D in the distinctive color, thus indicating that the machine is clear and set for decimal work.A

'may be printed and accumulated by depressing and releasing the ke 49" and operating the handle 27. An item of ten pence.

may then be added and printed by operating the key 49" and the handlel 27. A blank stroke et the handle being lirst taken, the

total ot the two items may, if desired, be recorded by another operation of the handle. An item of seventeen shillings may then he set up by operating the keys 49 marked l, 7 and 0 in the order stated. When the handle is operated, the item of seventeen shillings will be printed. In this printing operation, thepence type bar Ax oi courseV remains in its initial position, but the upper-l most type (D) or" said type carrier is not caused to print, because, as hcreinbcfore' stated, there in no lug 408 on the controlling lever 400 for that type bar, and the finger 411 is out of the path of the stud-- 412.

The subtotal 189 (denoting 18s., 9d.) having been taken, an item of ten pounds, two shillings, ten pence may be added and printed, the Naught key 49 being operated after setting up the pounds and before setting up the shillings.

A subtotal of the previous items, if desired, having been taken, an item ot 9 pounds may be set up by operating the keys 494 marked 9 and O, the latter key being depressed three times.

The final total 20017 (denoting 20, 1s., 7d.) may now be recorded, the imprint being accompanied by the Clear signal.

Although I have described the present embodiment of the invention in considerable detail, it is to be understood that the construction and arrangement of the various mechanisms may be modified, that the timing and relative order of operation of the various mechanisms may be changed, and that certain features may be omitted without departing from the spirit and scope of the invention as set forth in the appended claims.

it will be apparent to those skilled in the art that the rigid connection herein shown between the type carriers and their respective racks or actuators is not of the essence ot' the present invention, and that other well khown arrangements of the type carriers and racks or actuators may be employed.
