SPECIFICATION forming part of Reissued Letters Patent No. 12,296, dated. December 27, 18124:.

Griginal No. 630,053, and August 1, 1899.

To all whom, it may concern:

Be it known that i. HARRY H. Hnmnen, a citizen of the United States. residing at Chicage, Cool; county, Illinois. have invented new and useful improvements in Commuting-Machines, of which the following is a specification.

My invention relates to eoInputing-ma- I chines, and in particular to that class otcomputing'machines in which the figures and totale are printed upon a slip or strip of paper.

,()no object of my invention is to provide a romputing-machino which shall be of a simple and strong construction, which cannot readily get out of order and, further, to provide a device of this class which shall bone-at and compact and no upy but a small space upon a desk.

Another object is to provide a computing machine having a. series of t me-carriers to be moved to present the required figures at the printing-line. n combination with a frame carrying stops. said frame-and stops being movable to limit the movement of the typec: "icrs as reipiired when numbers are registcred Another object is to provide a computingnnichinc having a carriage and stops therein audio controlling the carriage and stops and a number of type-carriers movably mounted in the machine and devices for, movingthc carriage and type-carriers relatively, so that the steps which had b en acted upon by the keys will limit the throw of thetype'carricrs, and thereby cause the number which has been struck on the hers to be registered or presented at a given line representing the printing-linc.

A further and more particular object is to provide a computinganachine which shall operair in all-extremely easy manner. iew movements ol the hands being required.

A still further ob r-ct is to provide a marhino wherein the strip of paperand the numbrrs thereon are easily remlerod visible, a1n,l,-

further, to provide a; machine which will permit of a very rapid operation and will produce accurate and clear work even when the keys are manipulated at a high speed.

To these ends my invention cons sts gen- Application "for reissue filed Gemini 9, 1903. Serial lln. 175,40655 erally in a. coinputing-machine oi. the corn struction and combination of 'iarts. all as hereinafter described. and particularly pointed out in the claims.

'eral pin for each V snap back beneath the collar or shoulder on a ported by rollers 6, movable on a stationary track 4''. Small arms 8 are pivoted on the side of the carriage-frame to carry the toothed ratchet-bar 9. (See Fig. 52.) This ratchetbar adapted to be engaged by the doublepawl device 10, similar in operation and construction to the device for releasing a type- 1 and 2) on the The shaft 11 is supported writer carriage (see Figs. rocking shatt 11.

in the frame parts 12 and is arranged to be rocked back and forth through the use of the I lateral arm 13. connected with the depressionbar 14. (See Figs. 2 and i.) As shown in these figures, the depression-bar it has in wardly-extending arms 15. pivoted on the same shaft 16 whereon the keydevers l? are journaled. The spindles 18 of the ten keys 18 are adapted to move up and down through the guide-plate 20 and have their lower ends 1 l pivoted to the outer ends of their respective key-levers L7. These levers extend inwardly, and their inner ends are of the same length, measured from the shaft l6, and each has a broad fiat foot or end 21. adapted to engage oppositidy-positioned pins (see Fi land 2,)'and springs 22" are provided to draw back the keys after the steps have been locked in their raised position. Itrespective of arbitrary convenience characters I employ but ten keys, hearing or rep resenting the tennumerals 0, 1, 2, s3 4, 5, e, 7, a, and 9, the use of duplicates being rendered unnecessary by tho employnientof the shifting carriage 3, which by means of the stops 22 therein limits the movement of the type-carrying bars The stop-carriage 3 may be provided with any number of rows or series of stop-pins 22, each row containing nine pins, and the pins of each row being transversely opposite the key-levers 17 and keys 0 to 8, respectively. A 9 stop for all type-bars is pro vided in a fixed rib22 on the forward edge ofthe carriage; but manifestly stops may be provided for the 91s. as for the other figures or (See'Fig. 1.) The key-lever of the 9 key simply operates to release the carriage and allow it to move laterally one step. The stop-pins 22 extend through the top and bottom plates of the carriage 3 and are each provided with a shoulder or collar 23 near the lower end and are normally held down by lightsprings 24. (See Figs. 1 and 6.)

Alongside of each row of stop-pins 22 within the carriage 3 I movable locking-bar25, provided with a letstop-pin and adapted to pin when the pin is raised, The keys are operated one at a time, and the depression of a key. will raise thestop-pin which happens to be over the hue! end of its key-lever. At the same time that a key is depressed and immediately after the raising and locking of the 22 in the carriage,

provide a longitudinally-- stop-pin 22 the carriage is released by means of the rocking dog 10 and will travel one step toward the right of the machine. bringing the l next row of stop-pins over the inner ends 21 i of the key-lever 1'7. Successiveoperations of the keys 18' will therefore setup :1 single pin 22 in each row or riesof stop-pinsfus many pins being raised as there are keys depressed. except when the key 9 is struck, when the carriage is sim ply moved to th ight. Each movc mentot' the carriage 3 therefore represents a figure, and all the movements together. represent a given number. running from thousands through hundrmls, tens, units, and decimals or simply through units and decimals or through decimals only, according to the nu|ni 'ber of keys used. The numbers are then i practically set up in their proper order from to right. When the carriage is released, described, it drawn 211011;; by means of a spring 27, acting on the pivoted lever .26, connected to the carriage 3. At the end of a complete operation of the machine, the other portions of which will be hereinafter explained, the carriage is thrown back to the left or normal position by a rocking movement of the shaft 28, whereon the lever 26 is I secured, the ratchet-teeth of the bar 5') slippling back readily over the double dog 11). Yi'hcn the carriage is thus thrown back, all of the stop-pins 22 are released by the engagement of the outer ends of the locking-bars 25 with the stationary returningbz r 25), llXBll in the frame and having the beveled end or corner 30, the locking-bars 25 being thus forced back against the tension of their individual i springs 31. (See Figs. 1, 3, and 6.) l The stop-pins 22 in the carriage are employed to limit the forward thrust of the con1- bination type. and rack bars 32, of which there are as many as there are longitudinal rows or series ofstop-pins in the carriage. Each type and rack bar is provided on its upper edge with a series of tennumeral-types 33. while the lower edge of the bar'has gear-teeth 3-1, with which the adding-wheels 91 are adapted to mesh, as will be more particularlyexplained hereinafter. The bars are freely movable in longitudinal guides, and for each bar a bell-crank lever 36 is provided, the lever beingpivotcd on a transverse shaft .37 in the bottom of the casing, strong springs 38 being connected therewith. F roe movement of the bars and their levers is permitted by the employment of the slot-and-pin connections. l (Shown in Fig. 1.) The type-bars 32 are normally held back by a cross-rod 40, arranged between opposite arms 41, secured upon the main shaft 42 of the machine. (See Figs. 8

I up in the stop-carriage 3. l ver -13 has its lower end IIO shaft 42. and when the. lever is forced back the rod will obviously be swung down out of the path of the bell-cranks 36. thereby permitting the rack-bars to move forward when thus released, and when a fewer number of stop-pins are set up than there are rack-bars 1 provide a separate lock for the bars, said lock consisting in the transver Bly7H1U\&bl0 1 i1l or s'lideM, attached to the movable bars with the stop-carriage and so arranged that the first movement of the stop-carriage will carry the slide 44 beyond and out of the way of the first type-bar, the second movement beyond the second type-bar, and so on, so that just as many type-bars will be freed as there are keys operated. The type on the bars 32 and the stop-pins 22 on the carriage 3 are so arranged that whatever pins are engaged by the type-bars the type on the said bars will be in fore in each row the stop representing the 0 key will be nearest the forward end of the type-bar in the row of type-bars, so that in case two keys are struck at the same time the stop for a smaller key will cut out those representing larger numbers.

From the foregoing it is to be observed that the principle governing the cooperation of the stops 22 and the type-carriers 32 lies in the relative movements of the carriage carrying the said stops and the type-carriers, whereby the stops are moved into the path of travel of the type-carriers as required to'limit their movement irrespective of arbitrary direction of movement. \Vhile the form herein shown contains type-carriers in the formof bars which move horizontally, yet it is clear that the same principle may be adapted to any other forms of typc-carriers,whether circular, straight, arcuate, or oval, it only being necessary that-the keys operate the stops and act upon the escapement or pawl device controlling the stop-carriage, so that the latter may move or be moved to bring such of the stops 22 as had been set up into a position such that they will limit the movement of a correspondi ng num ber of type-carriers, and thereby register a number. -1 have shown the keys locatcd at the side of the machine and the stopcarriage moving parallel to the key-levers;

but other arrangements will readily suggest themselves, and no arbitrary awangement is necessary so long the relative movements desm'ibed result from the operation of the associated mechanism.

'lhoswinging movement of the erossrod 4:0, as shown in Figs. 1, .3 12, and 13, maybe employed to throw back the stop-carriage. As illustrated in Figs. 1, 2, 5, 7, and 12, the shaft 28, on which the lever 26 is secured, is provided with a beveled gear-wheel 70. A short shaft 71 is arranged transversely to the shaft 28 and has a bevel-gear 7'3. meshing with tin gear thereon. On the other end of the shaft 71 is an arm '73, connected by a pivotal link 74 with the lower end of a vertical lever 75. (See Figs. 1 nid 12.) The upper end of this lever extcni s nto the path of the moving rod 40, so that the rod is thrown back and up at the end oi the operation of the machine the lever 75 will be forced back to rotate the two shafts 28 and 71, operate the la vcr 26, and move back the carriage 3. To pre- 'vent the carriage being movedl .terally by the downward movement of the rod 4:0, I construct throwing out the clutch 78. a pull-button 79,

. connected with the clutch by a short lever 80,

being provided for the purpose. (See Figs. 12 and 13.) As a result of the stop-earl ebeing thus held stationary the stops which had been set up are not restored to idle posi tion, but remain to limit the throw of the ty e-- carriers, which may be repeatediy released by operation f the lever-t3 and opera ed by their springs, so that the same number Wlii be repeated or reprinted as many time the ver is operated, or until the clutch is set by pushing in the button 7's. wluirenp the stop-carriage will at the neat operation of the lever 43 be moved back to normal position and the stops 22 released and restored.

The total of all the numbers printed, whether repeated or not, will be accumulated by the adding-wheels, which at each operation of the type-carriers take up the number printed, as will hereinafter fully appear.

' 16 represents a paper-feeding roll arranged at the rear edge of the slot 45 and suitably supported in frame-bearings. The paperstrip 48 is carried upon the independentiy -supported roll 49 and is carried between the re" 46 and the idler-roll 50 and then out and across the slot. (See Fig. 1.) An inked ribbon 48' extends across the slot, and an advance mechanism is provided therefor.

52 represents a shaft arranged in bearings 53 and carrying as many hammers 52' as there are type-bars 32. (See Fig. 15.) 'llbese hammers 52 are loosely jonrnaled on the shaft 52, andfrom the end of the shaft an arm 54 projects down through the easing into position to be engaged by the pin or lug 55, extending from the lever 43. This arm 54 is secured too by a stationary rod 85. On the opposite ends of the rod 85 l locate similar levers 86, prothus thrust forward the pawl l7, pivoted upon the upper end of the arm and operating on paper-feeding roll il i. (See Figs. 1 and 13.) ITiRUliWlllLl movement of the roll is prevented by a springwletent rod 5!) 8X ends he tween the forward part of the arm Oi and a like arm on the other end of the shaft 532 and is parallel with the shaft 52 under the hammers 51-3, which are norn'ially upheld thereby. The hammers 52' have stop-shoulders 6 0 and are normally held against this rod'and are actuated by light springs 61, this arrangement being employed in order that the hammers may be independent from one another to strike type, which need not he of exactly the same height. itis obvious that the hammers must he released quickly at the time when the operating-lerer l3 is nearing the end of its stroke or throw and must. be held at other times, and for this purpose] provide a spring hook 63, conveniently journaled on the shaft 42 and adapted to engage an arm or lug 6i, extending fr in. the rear side of the arm 54. (See Figs. 1, 8,:n1d 13.) The hook 63 is thrown outot' engagement with the lug Ge by the pin or lug 55 on the opereting lever 43.,

. which strikes the hook 63 when the operatinglcrer is moved backward. Vr'hen thus released, the spring :36 snaps the arm backward, and thereby removes the cross-rod 59 from the shoulders 60 of the hannners 52, and the latter'arc thrown against the type by their springs (31. To raise the hammers 52 slightly oil the type after a stroke, 1 provide a small cushion-spring 65, on which the arm 54- rebounds. (See Fig. 1.) A suitable spring (56 is arranged a round the shaft 4:2 for holding the hoot: 6? forward. (See Fig. 13.) On the return of the operatingdever 43 to the posi tion shown in Figs. 1 and 13 all of the hammers will he raised and locked in a raised p0 sit-ion by the engagcnien-f of the pin 55 with the lower end of the arm 5% to swing the same up, so that the lug 6% will Catch beneath the shoulder on the hook By means of the mechanism thus far described a series. of numbers from oneto nine figures each may be printed upon the strip of paper in succession, the printing being done on the under side of the sheet, which may readily be rendered visible by simply turning back the paper.

So far the machine is complete. A machine of this class is not, however, thoroughly complete without means for addinga series of numbers and printing the total thereof, and l thereforeprovide an adding mechanism tooperate in connection with the rack-bars 32 ichin the casing I provide the two frame-standards 83, each of which is providedwith a slot 84 in its upper end.

(See. Fig. 1. f; no pziwls 97 are arranged upon the-shaft 96 extend be tween the adding-wheels 9i and are provided with the upwardly-extending and inclined lugs 98, (see Fig. 1,) adapted to he struck by the lugs 93 on the adding-wheel, tothe right thereof, the pnwls 97 controlling the action of one wheelupon thesunneeding wheel. Eaoh intermediate mechemsm is completed by a. vertical lever 10%, pivoted upon the station ary rod 85, provided with a lateral lug 102 and pivoted upon a cross rod or shaft 103, which rod is fastened to the lower forwardly-projecting ends of the parts 94 and moves therewith, as shown in Fig. 8. Springs 101 and 105 are connected with the lower ends of the levers 100 and 101, respectively, to draw the same back and throw their upper ends forward whenever released. The upper end of each lever 100 has the form of a segment of a gear to mesh with the teeth of the overlying adding-wheel 91 when the same is dropped into itslower position. (Shown in Figs. 1 and 10.) The lug 102 on the lever 101 is adapted to lie in the notch 106 in the pawl 97, and the rear edge of the lever 101 is adapted to engage the forward edge of the lever 100, in which position the lug 102 will be seated .in the notch 106 and lock both levers 100 and 101. When the pawl 97 is depressed through the engage- I ment of the lug 93 on the preceding addingwheel with the lug 98 upon the pawl, the lug 1102 disengaged from the shoulder on the pawl 97, whereupon the lever 1.01 will spring out of engagement with the lever 100, after which the pawl is held down by the lug 102. A stop 107 is preferably provided at the end of the pawl 97 to limit the movement of the lever 101. hen the lever 100 is thus released, its spring 101 will throw out its upper end, and thereby rotate the adding-wheel one tooth. The throw of the lever 100 is controlled and timed by means of a swinging cross-bar 108 to engage all of the levers 100 and itself adapted to be operated by the swinging cross-rod 10. W'hcn the latter is thrown down, the lever-arms 109 of the crossbar 108, pivoted on fixed shaft or shafts 110; will be released and be drawn up by the spring 111 to carry the cross-bar 108 up behind the levers 100. When the swinging rod 40 is restored; the cross-bar 108 will be moved be-. neath the projections on the back of the levers 100, thereby permitting the one which had been released from the lever 101, as above described, to be moved by the spring 104 to throw forward the upper end thereof and rotate the corresponding wheel 01 which is the process of carrying from a lower to a higher order. For restoring the two levers 100 and 101 a cross-rodl 12 is provided between the lower ends of the cam-levers 86, whereby as the operating levhr 43 is thrown back to raise the adding-wheels 91 with the pawls 97 and levers 101 the bar 112 will strike the lower ends of such of the levers 101 as have been previously released and move the same back against the levers 100 and thence into their normal position, in this way restoring the levers 100 and the pawls 97, While the said levers 100 are disconnected from adding wheels .11.. v i a and a second vertical lever 101,

the adding-wheels will be raised into engage ient with the teeth on the under side of the rack-bars after the bars have completed their forward movement. The shafts 96, 88, and 103 are moved vertically with the addingwheels, while the shaft 85, carrying the levers 100, remains stationary, so that when the adding-wheels are raised the teeth thereon will be disengaged from the segment-gear on the upper end of the levers 100. The addingwheels having been raised into engagement with the teeth of the rack-bars, upon moving the lever 43 forward the rod 40 will be brought into position to engage the upright levers 36, and as the lever 43 is moved still farther forward said levers 36 will be returned to their normal position, at the same time drawing therack-barS back and rotating the addingwheels that are in engagement with the teeth thereof.

Suppose the units-wheel to be rotated so that it stands at 9. It is evident that the next movement of the wheel will bring; the lug 03 into engagement with and along the inclined surface of the lug 08, thereby dcpressing the pawl 97 and unlocking the lever 101, which is thereupon operated by its spring 105 so far as the stop 107 will permit. The lever 100, which is normally held by the said lever 101, will at this time be prevented from moving by the crossbar 108 until such time as the adding-wheels have been dropped, so that the teeth of the same are in engagement with the upper end of the levers 100 and the bar 105 return movement of the rod 10 and in no case .does the rod 10 act upon the levers 109 to release the levers 100 until the adding-wheels have been dropped to their normal position When the levers 109 are moved to the position shown in Fig. 1, the levers 101 having been previously unlocked, as described above, the springs 101,, provided at the lower end of the lovers 100, will operate the same and advance the tens adding wheel one tooth.

1 Should the tens-wheel standat 1L" the movement of the rack-bar will cause the hr;- d; on the tens-wheel to depress the pawl 07 and unlock another lever 101 in the same manner as deserilmd with reference to the units-wheel. and theadding-wheels having been dropped back to their norinal position in engagrnmnt with the lovers 100 and the lever 100 being operated by the rod 10 the sprin 10%v will operate another lever 100 and advanre the hundredths-whoel one tooth.

The totals areascertained from the linal relative locations or positions of the addingwheels 01 or, more particularly, of the side lugs 93 thereon. 'llheso positions are ascertained by rotating all of the wheels in the opl positc direction from their ordinary inovement and until their lugs 03 strike the for- The tens are carried forward in the folloW-' ward sides of the lugs 08 upon the pivoted ing manner: By moving the lever 13 forward pawls 07.

As the pawls 07 rise with the wheels lug 93 coming in contact i I gae'ement therewith and the rack-bars then released. The springs 38, in connection with the rack-bars. will cause each of the same to more forward as l ar as the lug 93 upon its adding-wheel 91 will permit. The totals will then be shown upon the bars 32 by the type 33 beneath the slot 45 in the top of the easing 2 and may be printed therefrom.

Inasmuch as the backward movemcntof the rack-bars 32 is commonly employed for ro tating the adding-wheels 91 and computing the numbers from the, relative position of steps 22 in the stop-carriage 3 and as the opposite movement is employed when it is-desired to print the totals of the wheels, it is necessary to accommodate the parts of the machine to such backward or reverse movement. This I accomplish by simply chang ing the pivotal connections of the cam-lever links from above the centers of the operating-arms to equal distances below the same, so that a movement of the main lever 43 will result in reverse movements of the other parts.

Slots 114 are provided in the opposite'oper ating-arms 41, communicating between the slots 92 and the lower curved slots 115, into which the pins upon the ends of the cam-lever links 90 may be thrown by means of the pivoted adding lever or bell-crank 116, prefer ably arranged upon that side of the machine opposite the operating-lever $3 and journaled on the stud 116', as shown on Fig. 14. The

. link 90 upon this side of the machine is provided with an extension 90, pivotally connected to the lower end of the lever 116 by the link 90". The lever 116 operates against a strong spring 117, having one and secured.

to the side of the machine and its other to the extension 90. The opposite end of the link 90 is connected with the similar link 90 upon the other side of the machine by a rod 9]. (Shown in section in Fig. let.)

When it is desired to add the columns of figures printed from the respective type-bars, the lever 116 is thrown to the position indicated by dotted lines in Fig. ll, thereby raising the adding-wheels SH into engagement with the teeth 34 on the under side of the type-bars 32. and by operating the lever il each typc-| ar 32 will be allowed to moveforj ward until the adding-wheel with which it is 1 mg -lever is drawn toward the front of the in engagement is stopped by its lug 93 com ing in contact with thelug 9801 the adjacent i the upright levers 36, forcing;

pawl 97. As each adding-wheel ill had been rotated by the backward movement of the type-bar 32 as many teeth as its type-bar had been moved forward in printing the. column, it is obvious thatthe number ol teeth on each addinwwhcelill between the lug 93 and the lug 98 on the pawl 97 will rorrespoml to the number of units in the column to be added. and when ach allding-wluzel is stopped by its Ri -"the lug 08 the pe-l ar 39. beneath the slot 45 will indicate the sumot' the units printed from that particular bar plus the sum of the tens carried forward from the precednumeral shown on each ty ing bar. Further. as none of the type-bars 32 could move forward to perform the adding operation unless the locking-slide M upon the carriage was removed I provide a FOCliBl" arm or arms 118 on the rod 5 at the forward end of the machine and arrange a cross-rod ill) betweenthe ends of the rocker-arms llS, said rod being adapted to be raised by the engagement of the lever 116 with the inner end of the rocker-arm and this movement being utilized to swing or raise the ratchet-bar 9 on the carriage out of engagement with the donble pawl 1Q beneath it, so-that the carriage may move out and carry the lockingsiide 44. away from'the type-bars.

A simple arrangement for slowly moving the ink-ribbon 48' is shown in Fig. 7, wherein 120 represents spools upon which the opposite ends of the type-ribbon are turned and. 120' rolls over which the ribbon passosas the spools revolve. These spools 120 are arranged in connection with bevel-gears 120", adaptedto be engaged bybev l-pinions 12].", arranged upon a vertically-movable sleeve 121, geared to the vertical shaft 122.. The shaft 122 is permanently geared by bevel-gears 122' andv 122" to an extended end of the shaft belong.v ing to thepapenfeeding roll 46.

The direction of movement of the ribbon &8 may be altered by shifting, one or the other of the pinions on the sleeve into engagement with its spool. For shifting the sleeve'l provide a push bloclr 123, operated by-a knob 124, extending; through the side of the ens. ing 2'. v

Briefly, the operation of the machine is as follows: The operator strikes the keys and the carriage moves along to its proper position. By operating" the lever 43 the rod is moved out oltho path of the levers 36, and such rack-bars" as are not held in their normal position by the locking slide or bar is; are permitted to move forward against their 1 respective stops that are set up by the operation of the keys. During the movement of the lever -13 the hammers are released and are thrown upon the paper and cause the numerads or characters provided upon the rack-bars beneath to print thereon. l fhen the operatmachine, the rod -10 is brought/in contact with them back to their normal position, together with the raclo bars which have been previously released.

This movement also raises the hauuners to their noruuil position. The adding-wheels being raised into engagement with the reel;- bars will be rotated by the return mine-merit thereof. and should they be rotated beyond the $1 point. the lovers .ltll will be unloclieih therein permitting the levers 100 to advance the :Ulili!l; f-\\'li(i5l l one tooth when the lovers are operated by the return of the rod 40. During: the hac'iuvard movement of the rod 40 the carriage is returned to its normal position, so that the machine is in readiness to print the total or add another number, as may he desired.

From the foregoing description it will be seen that the act of carrying the tens is included in a single operation of the machine and is not in any way controlled by any subsequent movement.

It is obvious that the number of type-bars and the number ot'rows of stops in the carriage may be varied wild similar or other changes made in the construction of my machine. without departing from the spirit of my invention, and I therefore do not confine the same to the partici'ilar construction shown and described.
