SCHUMAN, of Louisville, .in the co inty of J efierson and State of Kentucky, have invented certain new and useful Improvements in Calculating-Machines; the following is" a full, clear, and exact description of the same, reference being had to the accompanyin drawings, which form part of this s eci cation.

This invention is an improvement'in calculating machines; and its objects are to provide a machine capable of performin operations in addition with accuracy and rapidity,

to, provide improved registering to provide novel key mechanism, to provide novel mechanism for ar resting or detaining the registering levers when no keys rtaining thereto are pressed, to provlde novel carry-over mechanism, to provide mechanism to provide a novel mechanism for indicating the last item recorded so that the operator'can always see machine what. was the last. item recorded without having to inspect theprinted record, to provide novel printingmechanism for recording the items and totals, to provide a novel type-hamm r-locking mechanpe alinmg mec rovide a novel totaling mechanmay be ascertained and printed at any time, to-provide a novel mechanism for indicating on the record whenever a total has been taken or the ma-- chine .reset to zero, to provide novelpaper carriers, to provide novelv repeating mechanism whereb items ma be repeated without resetting t e keys an to provlde a novel error-keywherebythe'keys may be released without operating the machine 1n case an error has been the keys. Y l

The invention will be clearly understood from the following descri tion, and the features and combinations 0 parts made in depressing desired are summarized in the claims; following the description of the machine as illustrated in the accompanying drawings, in

The machine embodies-a plurality of adding ;mechanisms arranged side by side and each constructed substantially alike and arcarries over at the tenth unit to the tens-wheel and so 'on up to. the total capacity such mechanisms for each denomination in themachinqwhich can sired capacity by simply adding additional duplicate mechanisms.

-The registering mechanism.-.-The regisistering-wheel is constructed with a m'ultip e of ten teeth-as shown, each has fifty teeth- -so that for each fifth of a revolution of the wheel ten numerals of its denomination will be counted and at every fifth of a revolution of a registering wheel 'of' lower denomination, mechanism is actuated to carry over or move the wheel of next higher denomination one tooth.

d as usual so that the units-wheel of the machine. There is one set of ,l j 8.

the decimal notation up' to the capacity-of be made of, any dea :tering-wheels 1 are loosely mounted side by side on a' shaft 1, journaled in the sides of frame of the machine; Each re r The levers are thrown backward by springs .1 when, the levers are released from control of the resetting arm, hereinafter described. The springs 1 mounted on shaft 1, as shown. The upper end of each lever- 1 is provided with a laterally projecting finger 1?, which moves in an are when thelever is oscillated parallel with and beneath a related row of keys3, and if any keyin such row be depressed it will arrest the backward movement of such lever. a

Each lever '1" carries a pawl 1 which is normally held in engagement with the teeth of the registering wheel by a spring 1, the pawl being pivoted on a pm or screw 1 attached to the lever. 'Pivoted on said pin 1 is a second pawll which extends in a I direction opposite pawl 19 and its tail engages a pin 1 on pawl 1, so that when one pawl is in engagement with the wheel 1 the other is out of engagement. Pawl 1 is conother on pin 1 so thattrolled by a spring 1 hun on the screw g 1 with one end bearlng on pawl 1 and the the spring 1 does not oppose thes pring l which normally holds pawl 1 in engagement with the wheel 1.

r The tail of pawl 1 projects beyond and above pawl l and is'provided with a pin 1 which at the proper times is engaged and depressed by suitable devices, hereinafter explained, to throw pawl ment with the wheel 1.

The levers l, are normally held in forward position against the action of springs 1 by means of a pusher 1', attached to shaftl, said pusher,'as shown, being in the 1 into engage- X form of a bail shaped bar. I Thepusher 1' -keyed on shaft 1,

. frame parallel with is adapted to engage projections I on le-. vers 1, as shown, so as not to interfere with the pawls.

The shaft 1 is controlled by suitable springs, so as to normally throw the pusher forward.

As shown in Fig. 2, a segmental gear 1, meshes with a segmental gear 2,-on a shaft 2, journaled in the main shaft 1. Shaft 2 is provided with a hand lever 2 on its outer End, by which it canbe rocked forwardly; ut

when'the lever is released the shaft is a'rocked" backward and normally held in attached to an arm 2 gaged by a plunger attached to a rod 2,

rearmost position by means of a stout spring 2, attached to an'arm 2. on shaft2 and to a suitable point on the main frame, as shown injFlg. 2.' As shaft 1 is geared to shaft 2, it is .gbvious that the normal position' of shaft I is that shown in Fig. 2, with the pusher 1' holding all the levers 1 in their: foremost position. [If desired, the re-- turn spring-impelled movement of shafts 2 and l may be cushioned by a dash pot 2" on shaft 2 and enare conveniently able ,ing plate 3 outward,

pivotally connected to the frame, as shown in F ig, 2. 4

The key boardr As shown, there are nine keys ineach row- (one row for each denomination). These keys 3 are-vertically movable, and their stems are mounted in slotted plates 3, attached to the frame, as shown.

The lower ends of the first eight key stems are curved so that their extremities will coincide with the arc traversed bv the finger 1 on the related lever l and will be equ1- distant, so that the space lever 1 in moving next will just sufiice traversed by the from one .key to the is normally upheld by-means of a suitable spring 3*, attached to the key and toa suit: point on the upper plate 3, as shown in Fig. 2. Each key stem has a ratchet tooth 3 on its side, which when the key is depressed catches under a swingingcatch plate 3 hung from the upper slotted plate 3* and normally swung inward toward the stems by a spring 3, pressed key until after the registration has been efi'ected,'when it is automatically disengaged from the key, as hereinafter described. This plate 3 moreover, prevents more than one key being locked down successively in any one row, and only the lastkey depressed will remain down, for if the wrong key is depressed and locked the op- 'erator merely has to push down the right key, which as it descends swings the lockreleasing the previously depressed key, while the last depressed key is held down. Thus if the operator discovers an error in his keyboard before actuating the hand lever 2 he can instantly correct it by merely depressing the proper keys without having any errors in computation arise. 7 7 j Preferably the stem of the ninth key is short, and when 9 is in its rearward movement until it strikes a stop bar 3 which is permanently fastened at the rearmost limit of movement of the levers 1 and-serves as a common ninth stop for all. thelevers 1 l The registering Zeoer detdinen-Jn order to, prevent the lever 1" moving rearward when no keys have been depressed in its related row, although it is released by the rearward movement of the pusher 1", I pro vide a retainer finger 3'", which is attached to the forward end of the related catch plate to move the registering-wheel l-one notch or tooth. Each key to be added on any one wheel the lever 1 meets no obstruct-ion so as to lock any de- 3 and depends just in front of the lever 1 when the latteris in'foremost position, Fig. 2t When' any key in such rowis 'depressed, however, the catch plate 3 outward, so as to move the detainer 3" out of-the path of finger 1 of the lever-1F, and as the catch plate cannot swing back to inis swung segment 1 said plate bein engage on its return movement (1f the detainer has swung back to operative POSI- tlon) and push the detainerout of the way,

so it will not be injured.

The key release-After each registering operation it is necessary to release thekeys' and this is priorto setting the next item, done as follows (see Fig. 2). Arranged at the front of the key board and extending past. the forward ends of the several catch plates 3 is a slide bar 4", which is suitably supported, so that it can be reciprocated longitudinally. This bar has a-series of inwardly projecting pins '4', which project near the adjacent ends of the catch plates 3, but lie normall out of contact there with. Bar 4 (see ig 1) is pivotally connected to one arm of a bell-crank lever'4 pivoted on the frame withits free arm lying below the keyboard in position to be struck by the free end of a vibrating lever 4, 'pivoted at 4" to the side of the frame.

Lever 4 has a depending arm 4", which extends downward towarda segmental gear 1 on shaft". On the lower end of arm 4 is pivoted a dog 4', which has a tooth dcpf/nding beside segment 1 and adapted to engaged by a pin 1 thereon. When rotates backwardly, pin 1 tilts the dog and passes thereunder without osoillatin lever 4; but .on the return movement 0 the segment pin 1 engages the dog,

and the latter being locked against a stop 4 on arm 4" said arm is swung forward,

raising lever 4 and causing its upper end to strike lever 4 and cause it to move bar 4 so that pins 4 thereon-engage the catchplates 3 and swing them outward or'away from the key stems, thus releasing all the keys. The pin 1 moves forward sufficiently to clear. dog 4, whereupon arm 4 and lever 4fare returned to normal position by a spring and bar 4 is also returned to normal position by a springA.

The carry-overr-k laterally projecting pin 1' is attached to the side of each wheel 1 adjacent'each tenth tooth. (In the. drawings there are five such'pins on each-registermg wheel.) This pin is adapted g1 one arm of a bell crank trip 5, ivoted on a swinging lever 5, hung on she t 1 beside the registering wheel and having its 1 lower end guided in a slotted plate 5, the

trip being controlled by a spring 5". The lower arm of trip 5 lies above a plate 5, loosely mounted on a. transverse rod 5, upheld by a springb", and a tooth 5 on p ate 5Pengages a notch 5' on a projection of the-next adjacent lever 5 without aifecting the shaft 5.

Now whena pin 1' on a wheel 1 of lower ment of the wheel to en-- pertaining to the wheel of next higher denomination and locks this lever in rearmost position, as indicated in Figs. 2, 3, 4 a ainst the tension of a sprin 5 which a ways tends to swing lever 5 orward. The lever 5 adjacent each wheel of higher denomination carries a pivoted dog 5 which is yieldingly held in engagement with the teeth of such registering-wheel by a spring 5. This dogwill trail on the wheel when the lever 5 is swung outward, but will move the wheel when the lever is swung inward. Anyreleased lever 5 will be moved back ward at the proper time by means of a bail 5".', attached to a rock-shaft 5, which is provided with an arm 5, carrying a dog 5', controlled by a spring 5, (see Fig. 2) said dog projecting into the path of a pin'l' on segment 1, so that when said segment is rocked by the forward movement ofhand-,

lever 2 the-pin 1 will engage the dog and rock shaft 5, so as to cause'the bail 5" to push the lever 5 rearwarduntil they are 5, and on V the return movement of the segment the dog 4 locked by the engaging plates will yield and allow the pin 1 to pass it denomination engages and actuates the related trip 5? cent catch-plate 5 the .lever 5 of the and causes it wheel of next higher denominaticn whereupon the said .lever is thrown forward by its spring 5." Then when the hand lever 2 is drawn forward shaft 5 is rocked, as described, and bail 5" pushes the released lever 5' inward sufficiently to cause its dog 5 to turn its registering wheel one tooth, and thus effects the carry-over operation. If the wheel of higher denomination just referred to 'happened to stand at the ninth tooth at the time its lever 5 was released by the moveof lower denomination, -obviously a pin 1 on suchwheel would in such case be in the path of the trip 5? on its related lever 5, so t at when said lever was swung backward by thereon would be rocked by the pin-; 1 on the stationary wheel and cause the'next j.

-catch-plate to release the lever 5 of the next wheel of higher denomination, so that when shaft 5 was rocked both wheels of higher denomination would be actuated and the carry-overs effected.

Rod 6* is moved carrying bars 7, each of in position to bring pinions 6 in mesh with the registering wheels 1 by means of an arm 6 attached to one of the hangers 6 and extending inward toward the segment 1 see Fig. 2) which'engages the inner end of :irm 6 when the segment is rocked by the'for- Ward movement of hand lever 2 and raises said arm, thereby swinging rod 6* inward and causing pinions 6 to mesh with wheels 1 before the latter are rotated.

Thus the leave the machine at any time and always can see at a glance what was the looks before again 2. The I printing mechaniem.The machine alinement,

rest ready for the t is provided with mechanism to print each ltemadded on the machine as follows: Attached to the levers 1 which carries tentype characters, (numerals 0 to 9 inelusive). Each type-character 7 is radially. movable in the bar and is held in position by aspring 7 which may be threaded through the several type, as shown, and permits each type to' be projected outward at the printingpoint' when struck by a hammer 7 as hereinaftcr explained- The type-carriers 7 are arranged close together, so that impressions from the type thereon will be properly related. Each type hammer 7 is mounted pivoted on a shaft 7",

hammer is cocked, a spring 7 connected to said arm and a point on the frame, being adapted to actuate the hammer. The arms 7 are engaged and moved inward to set the hammers by a push-plate 7 mounted on abail 7 attached to shaft 7 plate 7 lying behind arms 7 and being normally held by a spring 7 at such an angle that when bail 7 is swung in-, ward plate .7 will engage arms 7 and push them inward, setting the hammers against the resistance of springs 7*. After the type are in position to print, plate 7 which continues to move inward, is tripped by means of a finger 7 engaging a stop 7 Figs. 3 and 4, and caused to release arms 7, whereupon springs '7 throw the hammers against the type, and the latter are forced outward and make an impression on the paper carried by the paper carriage, hereinafter described. The shaft 7" is rocked so as tomove plate 7 as described, by means of a crank arm 7, connected by a link 7 witha pin 7 on segment 2 (See Fig. 2).

and 4, which is loosely andis provided with i are curved typeat the proper time,

The type alz'm'ng devi0e.Above shaft7 is a shaft.7, on which are arms 7 that ex tend toward the'hammers 7, belowthe tops thereof. To these arms 7 is pivoted a bail shaped bar 7 which is adapted-to come underneath a row of alined types, preferably in a row beneath those at the printing point, and is then rocked so as to engage such types and bring them into exact "so that the printed record will appear perfect. The bail 7 is moved rearward after the type-carriers have come to printing operation means of a cam-s1ot7 in a plate 7' attached to. shaft '7 and actuated thereby, said slot 7 being engaged by a pin 7 attached to shaft-7', so as to impart a p opeigrocking motion to shaft '7' then hold said shaft momentarily at rest, a suitable dwell being provided in slot 7 for this purpose.

but terminate at the'proper time and While bail 7? is thus held in its rearmost position a forwardly extending on the bail is engaged by the pusher ts catch 8 on arm .7 attached tos aft 7', so-

rearmost position, and bail 7 is elevated slightly so as to engage the type, as describe and hold them momentarily. in alinement while the hammers strike them. Then as pusher l moves back thejbail is released, andthe bail drops back out of the way as the shaft 7' returns to. normal position. In order to aline the"0 type on such carriers as have not been moved, Ipr'o vide apin '7 on the inner end of each carrier (see Fig.4) which willbe engaged by bail 7 during the alining operation; if such carrier has notbeen displaced.

The type hammer loch-In order to prevent the hammers printing ciphers to the left in cases where wheels of higher denomination have not been moved, I provide devices for locking such hammers when cocked,

as follows; -On a bar 8, in front of and SH htly above the hammers, is a slide 8,

which is. rovided with a depending part 8",

that is a apted to pass in rear of the up 1' ends of t he hammers after they are coc ed and will prevent the hammers springing back when released b plate '7'. As only the left-hand hammers s ould be locked, the inward movement of slide 8 is automatically controlled b the type-carriers, said. late bein prov'i 'ed with a bayonet shape finge r which projects in rear of the ham-., mers see Fig.- 5)-and is adapted to contact with t 'e type-carrier of the wheel of highest denominationthat has been shifted and arrest the slide, sothat it onlylocks the hammers to the left of such carrier. usewill operate as above described. Then after bail 7 has returned to its normal. position,

' .Fig. 4, the slide 8 is moved back out of the w'ay,.soa.s not to interfere with the next setting operation of the hammers, and the re- I leased hammers fly back, but they are arrest-- ed by bail 7' before they can-engage the type. Slide. 8' is .moved inward at the roper time by means of a link 8, connected to an arm 8 on a vertical rock shaft 8, a spring 8 drawing the slide inward (when permitted) until itis arrested by. finger 8 strikin a -type carrier, as above explained. The 5 dc is positively moved out of the way at the prbper time and held out. of the way until 1 the plate 7' cocks the hanimers by means of a pin- Son shaft 8 which is en aged by a i that when-the shaft? is rocked backward loc the latter .in the position to which it has been drawn b catch'S (see Fig. 2) and hold it while sha 7' and catch 8' rock forward and until a pin 8 on link 7 strikes the upstanding arm of the detent and causes it to disengage pin 8, whereupon spring 8 throws the slide into locking position until-it is arrested by finger 8 striking a type carrier, as indicated in Fig. 5.

The totaling mechanism.-In orderto print the total amount which has been added at,any time, I providethe followin devices (see Fig. 3). 'A key stem 10 1s arranged atone side of the machine and is pivotallyconnected at its lower end to an arm 10 on a shaft 10", which shaft has a series of fingers 10,extending inwardly and normallyoverlyi'ng; the pawls 5 (see Fig. 4)- so that when the ey is depressed said fin-v gers will disengage said pawls .5 from the wheels 1. The stem 10 is also pivotally connected to an arm 10 on a shaft 10,Fig. 3,

to which is attached a series of curved arms 10, which extend over the awls 1' and are adapted (when stem 10' is epressed) to engage pins 1 on the tails of pawls 1: and

throw said awls' out of engagement with wheels 1 and at same time cause'pawls" 1 to engage with said wheels, thearms 10 being long enough to hold the pawls in this condition during the entire movement of levers 1", the pawls 1 trailing under the curved arms. Arm 10 is connected by a link 10 with a bell crank 10*, pivotally connected to the bar 4", so that. when arm 10 is depressed said bar 4" is shifted so as to swing the catch plates 3and move detents 3' out of the way of lever's 1 and hold them so as long as key 10 is depressed. On shaft 10" is a pin 10, .Fig. 2, which is adapted to engage a lug 5' so as to disengage finger 5} allow rod 6" to swing pinions .6 out of mesh with the wheels 1, as above described. All these operations bein performed on the depression of stem 10, t e operator then draws levers 1? from pusher 1', whereupon said, levers 1"" hand-lever 2" forward, freeing are. thrown backward by their. individual springs, and as pawls 1 are then in mesh with wheels 1- said wheels will be rotated backward until their "pins 1 come against the rear side of the trip 5, Fig. 4, whereby the wheels are I arrested with the small ,wheels at 0, and the" proper type will 'then be arrested at the printing point, and

thetotal is printed immediately thereafter before the hand'lever completesits forward strokes If the stem 10 be held down while the-hand lever 2 is making its return stroke,

thenumeral disksv 1' will remain reset tozero; but if the stem 10 be released before the hand lever is returned-pawls 1' will enon shaft 5 and rock said shaft,

from pin 6 and gage thewheels 1, -andr the wheels 1 and the tions they had before the total key was depressed. i .-'.The..tot'als and Subtotals may be printed numeral disks will'assume the same posiin a distinguishing ink, as hereinafter ex plained.

In order to prevent the total key being depressed accidentally or to prevent said; 5 key from springing up to normal position,

operation and the machine reset to zero, the fact will be automatically indicated on the printed record by the following mechanism whenthe first item in a new transaction is printed. On the shaft 7 beside the bail 7 is loosely mounted a type lever 17, carrying on its'upper end a single type character '17, preferably an asterisk or other peculiar character which lies in position to print on the paper alinedwith the other type atany printing operation when said type lever 17 is permitted "to operate. This lever 17 is controlled by a spring 17". The lower end of'the lever projects below the shaft 7, and on this lower-end is a pin 17 whichnormally contacts with one ofthe members of bail '7 which rocks the lever 17 as it vibrates and ordinarily keeps the type-lever 17 from printing. Below lever 17, but adja cent its lower end, is a bell crank catch lever 17, pivoted on a stud '17 and controlled by aspring"-17 One arm of this lever projects toward" pin 17 and is adapted, if raised, to engage said pin and prevent the lever 17 returning 'to normal position after being moved backward by bail 7 The lever 17 normally lies below the path of pin 17; but it is connected by a spring 17 and link 17 to an arm 17 on shaft 10,

lever 17is lifted against pin 17 placing spring'17 under tension, and when bail 7 is drawn forward the'pin' 17 will move down, allowing 'the catch lever 17 to be drawn forward by spring 17, so that if the total key is held down during the entire oscillating mover'nentfofhand-lever .2" the catch lever 17-;wil1 remain in front of pin 17 in position to engage said pin'and to lock lever 17 when total-key is released, (see Fig. 4'), but at-the next printing operation of the machine (preceding which plate 7 is swunginward to cook the type hammers) as above described, about the time that plate 7 is tripped to release the type-hammers, the -lever 17, is tripped, 'so as to release typelev'er17 and allow it to make an impression Ion-the paper lever 17 being tripped at the proper time by means of. a fing"er 17 on e5 bail :7 (See Figs. Land 4). The asterisk so that when the stem 10 is depressed the bar 9 maybe retracted by a spring 9 By .normal position and'will not'lock lever 17,

and at the next printing operation of the machine type lever 17 will not make an impression on the paper.

The paper 0arm'er.At the rear of the machine is a platen roller 9 and coacting feed roller-s9 9 which are journaled in brackets 9 and 9 mounted on a frame 9 which frame is slidably supported on a rod 9', attached tothe main frame (see Fig. 3.) The platen frame9 is provided with a rearwardly extending finger 9 which can be engaged with any one of a series of notches 9 in a transverse plate 9 attached to the main frame, and which will hold the carriage .in-an'y position to which it is adjusted by hand, the platen carriage being raised or tilted by hand so as to disengage finger 9' from any notch andthen the carriage moved right or left until the finger is under the desired notch, when the carriage may be released and remains in such position until again shifted by hand. The platen roller 9 is provided with the usual finger manipulating button 9 on one end, also with a ratchet 9 which' is engaged by a pawl 9 pivotally mounted on a swingin plate 9", to which is attached a longitudmally disposed bar 9, that extends the length of the roller 9. When the platen carriage is lowered, this bar 9 lies in front of. an oscillating 'lever 9, which is loosely mounted on shaft 7 and vibrated by means of a link 9", attachedto arm 5 on the shaft-5. (See Fig. 2), Lever 9 oscillates bar 9, so as to Totate platen 9 and turn the paper forward one line after. each printing operation. The

this construction a series of columns may be printed on the same sheet of paper at successive operations, the paper carriage being shiftedby hand from one notch 9 'to an other after' each column is finished. The inking ribbon is passed between the type and platen, as indicated in Figs. 2 and 3. Preferably I employ a two-color ribbon, and the ribbon spools 9 are slidably keyed on rotatable rods 9 -(see Fig..' 5)

which spools are yieldingly upheld by s rings 9. The rods have ratchets' 9 on t 'eir lower ends engaged by oscillating dogs 9-, whichare shifted by any suitable means so as to-enable the ribbon to be wound or unwound from. one spool to the other at will.

The ordinary item printing'may be done on the lower side .of the ribbon, which, for example, may be blue, while the total and. subtotal printing maybe effected from theuprise and sprin per part of the ribbon which is, for example, red. In order to shift the ribbon spools at the proper time, curved fingers 10 are at tached to shaft 10", and when the total key is depressed, as above explained, saidtingers 10 contact with and depress the ribbon spools 9", so that the red part of the ribbon is between the type and paper, and held there while the total orsubtotal is printed. When the item 10 is released fingers 10 9 raise the ribbon-spools so as to bring t e blue ribbon into place for making the ordinary item-records.

The repeat sires to repeatthe same item a number of times, he can-do so without setting the keys but once by means of the repeating key 14, the stem 14 of which normally lies just above the tail of the trip pawl 4 on-the arm 4" of key releasedever 4. When key 14 is depressed, its stem en ages the tail of dog 4' (see Fig; 2) and W111 hold said dog out of the pat of in 1 so that the key release lever 4 wi 1 not be operated, and the item may be printed-a number of times in succession by holding key 14 down an osout of the way,

cillating. hand lever 2", as above described. Stem 14 may be provided with a notch 14 which can be enga ed with the upper guide plate to lock the ey depressed by simply pushing the key 14 toone side after it is depressed. When the key 14 is released, it is thrown upward by a spring 14 and remains and the lever 4 then causes the release-of the keys as above described.

E'rror-key.-If at any time the operator should set up a wrong item on' the keyboard anddiscover his error before printing it, he can correct it b depressing a key 13, whose stem 13' exten s into close proximity to arearward extension 4 of Iever 4, (see Fig. 2) and by depressing this key lever 4. is oscillated and caused to shift release-bar 4", and all the keys-are released and may be reset. 1
