OF DAYTON,- OIIIO, ASSIGNOR TO Till-I NATIONAL (JASIl REGIS'TIR COMPAXY, OF SAME PLACE SPECIFICATION forming part of Letters Patent No. 622,445, dated April 4, 1899. Application filed m 23,1897. Serial Ra. 645,743. on mini Tool/1 whom. it um concern..-

lleit known that l, JOSEPH P. CLEAL, acitizen of the United States, residing at Dayton,-

' lar form of machine.

' "My invention consists in applying indicators to this class of machine, so that the oporator can always tell if he has made a mis- 20 take by an inspection of the indicators. In

, 6 the operator presses the keys, and the indicators show instantly what amount he has reg1'stcred,-and if a mistake has been made he can detect it immediately. Afterward by z 5 the pressure of the release-key the indicators are all returned to zero position preparatory to it new registration.

Referring to the drawings, Figure 1 shows a'top'plan view of an adding-machine with my indicators applied thereto. Fig. 2 is a vertical longitudinal section on the line 2 L of Fig. 1.

The same letters of reference designate iden- ='-tieal-parts in both figures of the drawings. 5 Referring to the drawings, the letter A designates various lixed parts of the frame or case of the machine. The hey-s1 which are arranged in eight banks of nine keys each, pierce the top of the case A, and the lingerbuttons (1 are, as usual, secured upon the upper ends of the keys, which are held in nor mal position, as shown in Fig. L, by the coiled springs (1', which intervene between the linger-buttons and the top of the ease. The 5 lower ends I) of the keys are of reduced diamctcr and pierce the rcgistcringdevers C, only one oi which isshown, although the machine comprises eight, of which one coiiperates with each of the eight banks of keys. At the upper end of the reduced portion of the key is formed a shoulder It", which rests the machine, and each has a lateral flange f.

The stop-motion detents G, one of which cooperates with c ach registering-wheel, arelikewise pivoted upon a transverse shaft-g, and a link g connects the stop-motion detenta'nd the stop-lever F, as shown in Fig.'2. The lower ends of the keys are graduated in length,

as shown, for a. purpose to be presently dcseribed. If one of the keys be pressed, it moves its lever C downward and directly actuates the registering-wheel. As the key nears the limit of its downw rd movement its lower end If contacts with the stop-lever F s and depresses it, the motion being transmitted through the link y to thestop-motion detent G, which thereupon engages and locks the registering-wheel against further movement for the purpose of preventing over-registration.

The parts and their cooperation as I have thus far referred to them are old and well known, and for a more detailed description reference may be had to the Felt patent, before referred to. My invention consists, as before stated, only in applying indicating devices to such a mechanism. 0

Secured upon the top of the case A are side frames ll, supported in and extending between which is a transverse shaft I, mounted to turn upon which are the indicator-frames J, supporting the segmental indicators J. A 5 segmcnt-ratchct J is formed upon the rear end of each iiulicator-frnlne. 'lurning upon the shaft I and rigidly secured to the indi cator-frames upon the left-hand side thereof are the hubs i. ecurcd to each indicatorloo frame, upon the right-hand side thereof, and also turning upon the shaft I are the ratchet- "wheels j for a purpose to be presently described. Cooperating with each indicatorframe J is one of the series of bcltcrank levers K, which are pivoted upon the transverse shaft 7. within the case A. To the end of the horizontal arm I." of the bell-crank levcris pivoted adepend ing member Licarrying a pin I.;",\vhich has a bearing against the under side of the lateral flange c of one of the lovers C. The vertical arm of the bell-crank lever is slotted, and in this slot works a pin or stud 7;", which is fixed to the in dieator-frame. Pivoted upon a transverse shaft L, which is supported at its end in and near the ends of the side frames II, is the torwardly-cxtcnding re-' lease-lever 1, upon the front end of which is a finger-button L.- Picrcing the release-lcver and extending laterally on either side of it is a rod 7, which is carried by and moves with the release-lever for a purpose to be presently explained. The braces i turn upon the shaft L and at their forward ends are socured to the transversely-extending rod 1' to hold the latter rigid with respect to the release-lever, the release-lever, the rod 1, and the said braces thus forming a rigid frame which turns upon the shaft L. Iivotcd above and slightly in front of the rod l',upon the shaft M, are a series ofdetents m, the upper ends of which are held in engagement with the segmeut-ratchetsj' by the coiled springs m, only one of which is shown.

The lock-levcris pivoted about centrally upon the transverse shaft 7.: and its lower arm N carries a pin a, the .upper end of which bears against the under side of the flange f of the stop-lever F. The pin it is held in contact with the said flange by the coiled spring 11,, which is secured at one end to a transverse bar n. and to the upper arm N at the other. The upper end of the arm N is tooth-shaped, and when the stop-lever F is moved downward the upper end of the arm N is thrown forward into engagement with the ratchetwheel J to lock or stop the indicator J, as will be readily understood.

The practical operation of the machine with myinvention applied thereto is as follows: Ifone of the keys be pressed, the swinging end of the lever C will be moved downward and its segment-rack 0' will actuate the countor. As the key nears the lower extremity of its movement its lower end I) will contact with a flange f and move the lever 1" downward, the motion being transmitted to the stop-motiondetcnt G, which is thereby thrown into engagement with the registeringwheels to lock the latter against further movement. As the lever C moves downward it throws the vertical arm of the bell-cranklcver K for ward and the segmental indicator J will be swung upward. A series of numbers from U to 0, inclusive, are imprinted upon the convex surface of the indicators, and as the latter is swung upward the numbers sueccssively pass the sight-opening 0 of the easing 0 (shown in broken lines in Fig. 2) until amount. If so, he presses the figure corresponding with the operate key is brought in position to show throng the sight-opening, and at this time the ind cater-frame .T will be automatically steppe by mechanism which I shall now describi When the stop-lever F is moved downwar by the operated key, as above explained, tl tooth carried by the upper end N of the loci lever is thrown into engagement with tl teeth of the ratchet j, thereby bringing tl indicator-frame, and consequently the ind cater, to rest and preventing the possibilii of its being moved too far. At the san time thedetent in will spring into engag ment with the ratchet j to prevent the int eater from returning to ward normal positio When a key is pressed, the devices that have thus far described operate to move tl indicator so that its proper number will shc through the sight-opening o and to then sti and lock the indicator in this position. return the indicator to zero, it is only met sary.to press the button L, which will cl press the release-lever l, whereby the rod will be moved downward against the re: wardly-curved lower end m of the detentc whereby the detents will be thrown and he out of engagement. The springs m willi stantly return the frame J, the bell-crank ver K, and the indicator J to normal p0 tionL The transverse stop-rod P is to p vent the indicator from going past noru position on its return movement.

In. practical use the operator presses t keys B to register the desired amount. can then glance at the indicators, and be (1 tell instantly if he has registered the corn the release-key,a the indicators will then be returned to Z1 position, readyfor the next actuation of 1 keys. In banks, for example, where my vention finds a large field of usefulness, i often necessary to add the amounts of a la number of checks or notes. It a single u take is made, it may lead to serious eon qucnces, so that myinvention will be of gr utility as enabling the operator to check 11 self after each registration, thus insuring accuracy of his work.

Having thus described my invention claim as new and desire to secure by Let! Patent of the United States- 1. In a device of the class described, combination with a series of operating-ki of an operating-lever engaged by the sam pivoted indicator having a projecting s and a pivoted bell-crank lever connected one end to the operating-lever and having opposite end slotted to receive the said st 2. In a device of the class described, combination with a counter-operating 1c of a series of keys arranged to normally gage said lever and project below the sa a stopdever arranged below the operating ver so as to be engaged by the proj ectingc of said keys near the ends of their stro an indicator, means connecting the indie t0 the operating-lever, and stop means connected to the stop-lever and arranged to engage the indicator to prevent its overthrow.

3. In a device of the class described, the combination with a counter-operating lever,

t series of keys arranged to operate said le- .er, an indicator, means connecting the 0pcrating-lever and indicator, a pivoted pawl arranged to engage said indicator and hold it in its set positions, and a pivoted key-lever having a projection which engages and operates said pawl to release the indicator without operating any of the other portions of the machine.

4. In a device of the class described, the combination with the registering-wheels and the keys, of an indicator cooperating with the keys, the lever arranged to actuate the reg istering-wheels, the stop-lever, the bell-crank lever connected to the indicator at one end and to the registeractuatin g lever at the other, the ratchet-wheel carried by the indicator, the lock-lever connected to the stop-lever at one end, and bearing a tooth at the other which cooperates with the said ratchet-wheel to lock the indicator against excessive movement.

In testimony whereof I afiix my signature in presence of two witnesses.

JOSEPH P. CLEAL.
