Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed March 15, 1904:. Serial N0, 198,244-

To all whom it may concern:

Be it known that T, JOSEPH P. CLEAL, a

citizen of the United States, residing at Dayproved forms-of mechanism for the screens or the flashes which hide the indicators.

One of the particular objects of my invention is to provide a novel arrangement of indicator-tablets which shall be compactly situated to indicate at a series of sight-openings, one sight-opening for each bank orgroup of keys, whereby the correct indication of the amount of registration may be correctly and easily read through said sightopenings in the manner in which said amounts would ordinarily be written or printed, and I have also provided means for indicating in this manner both at the front and at the rear of the machine.

Another one of the objects of my inven: tion is .to provide improved screen or flash mechanism whereby to conceal all the indicating characters which are not necessary for the proper reading of the indication-such, for example, as superfluous indications in the banks of higher denomination which are not used in any particular amount'registration.

With these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form. of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

()fsaid drawings, Figure 1 represents a rear elevation of my machine. Fig. 2 represents a cross-section on the line 2 2 of Fig. 1. Fig. 3 represents a detail elevation of the rack-bar for rotating the main operating-shaft,showing the key-coupler sectionalized. Fig. 4 represents a detail front elevation of one of the indirzator-yflates. Fig. 5 represents a front ele vation of the upper portion of the machine,

showing the indicator mechanism with certain of the registering portions of the machine removed for the sake of clearness; and Fig. 6 represents a top plan view of that portion of the machine which contains the indicatorplates, which portion is shown in Fig. 5.

T have herein shown my improvements as applied to the type of register described in Letters Patent to Thomas Carney, No. 497,860, dated May 23, 1893; but it is of course to be understood that I do not for any reason wish to be limited to this construction of cash-register, since my improvements are equally well adapted to various other forms of cash-registers. I shall describe only so much of this style of machine as is necessary for a clear understanding of my invention and forthe general operation of the machine,

and for a more detailed descri tion of this kind of machine reference may e had to the aforesaid patent.

Referring to the accompanying drawings,-

a series of keys 10 are pivoted u on a transverse shaft 11 and are arrange in various banks or groups of values graded in denominations from units of cents to tens of cents rocking of the key-coupler reeiprocates said bar '17. This rac bar is slotted at its lower portion 18 to straddle a pin 19, plliojecting from the mam frame of the mac ne, an

said lower portion is normally drawn rearward by means of a spring 20. By means of a lug 21, formed on the rack-bar 17, and a stationary lug 22, formed on the main frame of the machine, on the upward reciprocation of the rack-bar 17 the one set of the teeth of the rack-bar 17 engages with a pinion 23, fast upon the main operating-shaft 24 of the machine, and upon the downward reci rocation of the rack-bar 17 its other set of teeth engages with the same pinion 23, so that upon the complete upward and downward movement of the key-coupler upon the depression. of any key this main operatingshaft 24 is given one complete revolution. Attached to the rearward end of each key is a lifter-plate 25, and these lifter-plates are formed with notches 26, arranged at graduated vertical distances above the lower ends of the keys and arranged to engage atransverse shaft 27 of the registering-frames 28 at different points in the depression of the key, whereby to transmit to said registeringframe a variable rocking movement commensurate with the value of the key depressed, and this variable rocking movement of said registering-frame 28 may be transmitted to any suitable counting devices. (Not shown herein.) All of this mechanism heretofore described is old and is set forth in detail in the aforesaid patent.

Resting upon the rear end of each key is a vertical indicator-operating rod 30, which corresponds with the stems of the tablet-indicators described in the aforesaid patent, but having the tablets upon the upper ends of these stems removed and cooperating with another form of indicating mechanism to be described. Th se rods 30 are arranged to slide vertically in suitable slots formed'in the transverse bars 31 and 32, extending between the side frames of the machine. Each of these rods 30 is formed with a horizontal rearwardlyeprojecting arm 33, which is bent lat-- orally at its rearward end to form a wing 34, (see Fig. 1,) and these wings 34 are arranged to cooperate with antifriction-rollers 35 and 36, (see Figs. 1 and 5,) formed u on the down wardly-extending arms 37 of be l-crank levers 38, pivoted at 39 to a cross-bar 39, extending between the side frames of the machine. The upper arms 40 of these bell-crank levers 38 are formed with slots 41, which engage pins 42, projecting from a series of sliding indieator-plates 43. These indicator-plates 43 are mounted side by side, as shown in Fig. 2, there bein one of these plates for each of the aforesaid bell-crank levers 38, and it will be apparent that in order to have this arrangement of the indicator-plates 43 side by side, each connected with one of said bell-crank levers, these bellcrank levers must be displaced laterally one from the other, as shown in Fig. 2, being arranged in gradual lateral displacement from the rear of the machine toward the front of the machine, beginning with the cents-bank of keys. Likewise in order to have the aforesaid wings 34 in position to cooperate with the beveled rollers 35 and 36 upon these laterally-displaced bellcrank levers the arms 33, carrying said wings '34, will also have to be of graduated lengths from the cents-bank to the dollar-bank, being of such length as to bring the wings 34 into the path of the said rollers 35 and 36 for their respective'bell-crank levers.

I have arranged the cents -bank of my machine with nine keys from one cent to nine cents; but I have arranged said keys to act in pairs upon the bell-cranks 38that is, the one-cent and two-cent keys both act upon the bell-crank lever farthermost to the right, (see Fig. 5,) the wing 34 on the oneeent key being normally in line with the antifrietion-roller 36 on said bell-crank lever and the wing 34 of the two-cent key being normally in line with the antifriction-roller 35 on this same bell-crank lever. Thus it will be observed that since in'the normal position of rest of said keys said wings 34 are all at "the same height the depression of the one-cent key will raise its rod 30 and cause its wing 34 to contact with the roller 36 and rock the bell-crank lever 33 about its pivot 39, whereas the depression of the two-cent key will raise its rod 30 and cause its wing 34 to contact with the roller 35 at an earlier point in the stroke of the key, thereby moving the bell-crank lever 38 to a greater extent for the purpose to be described. Similarly the three-cent key and the four-cent key act upon the same bell-crank lever, being next from the farthest to the right, (see Fig. 5,) to give said bell-crank lever a graduated movement, the four-cent key moving the same to a greater extent than the three-cont key. Likewise the remaining cent-keys arc arranged in pairs to operate upon their respective bell-crank levers to give the same graduated movements, there being one lever for each air; but of course for the nine-cent key t ere can only be one bell-crank lever, and consequently there is no roller corresponding to the roller 35 upon this bell-crank lever, but simply a single roller 36, which eooperates with the wing 34 of the nine-cent key to move the bell-crank lever and its attached indicator-plate, as will be seen in Fig. 5, upon the fifth bell-crank lever,eounting from the right-hand end of the machine. This arrangement of bell-crank levers one for each pair of keys, with a single nine-cent ke aeti-n upon the corresponding nine-cent. be l-cran lever, is duplicated in the bank of keys for the units pf tens of cents and for the bank of keys for the units of dollars, and it will be apparent that where two keys act upon the same bell-crank lever the rearwardly-ext ending arms 33 of the aforesaid rods 30 may he graduated in length by pairs, so as to be in correct lateral alinemcnt with the graduated lateral displacement of the bellcrank lovers. The usual form of pendent back hangers 48, cooperating with the rear ends 49 of the keys, serve to prevent the operation of more than one key at a time in any bank, all of which is well known in the art and is not described here in detail, since it constitutes no part of my present invention.

I will now describe the connections hetween the aforesaid indicator-plates 43 and their respective indicating-tablets, which are tration.

character, which in this case'is one of the numerals corresponding to the value keys. (See Fig. 4.) Since, as heretofore explained, I have arranged to give these indicatorplates 43 a variable movement according to which one of a pair of keys is depressed, I may thus mark upon the aforesaid tablets 53 as many indicating characters as there are separate variable positions of the aforesaid indicator-plates '43, which in this case for all the first eight keys of each group comprises two separate indicating positions that is, in the cents-bank I may mark upon the tablet attached to the first indicatorplate both the figures 1 and 2 and upon the tablet of the next indicator-plate the figures 3 and 4, and so on, and upon the indicator-plate for the nine-cen-tkey, of course only a single numeral would be placed, being the 9, and this arrangement is duplicated for the other banks.

, At the top of the machine I have provided two cross-strips 54 (see Figs. 5 and 6) to conceal these indicator-tablets from the front and from the rear of the machine; but these strips 54 are formed with three sight-openings 55, one for each group of keys, throughwhich the indication may be read when the indicator-tablets are moved into position in the manner to be described. A similar series of sight-openings 56'is-provided at the rear of the machine, as shown in Fig. 1, in order to display the indication at the rear of the machine, also by means of mechanism to be described. The normal relation between the aforesaid tablets 53 and the sight-openings 55 at the front of the machine is such that no tablets are visible through these sight-openings except certain tablets bearing a zero indication, the purpose of which will be set forth later. When, however, upon the operation of any key the bell-crank-lever corresponding thereto is rocked in the manner previously described, the indicator-plate 43 attached thereto is shifted to the left, (see Fig. 5,) thereby carrying into indicatingposition one of the lndicating characters u on the tablet 53, the correct display depen ing upon the extent of movement of said indidicator-plate, as will be obvious from the description of the mechanism heretoforegiven. Thus when the one-cent key is depressed the indicating-plate corresponding thereto is given a certain extent of move ment enough to carry the figure 1 into' view at the right-hand sight-opening 55, (see Fig. 5,) whereas if the two-cent key is depressed this same indicator-plate 43 is given a greater extent of movement and the figure 2 upon the same tablet 53 is brought into view at the sight-opening 55. The duplication of this arrangement throughout will be I apparent.

In order toprovide a zero indication in the case in which no key in the cent-bank is depressed, I have made the tablet 53 of the indicator-plate for the one-cent and two-cent keys of slightly greater width than the ordinary tablets for the purpose of having marked thereon a zero, and in the normal position of this tablet'this zero stands directly opposite the sight-opening for the cent-bank,

so that if no key in the cents-b ank is operated this zero will show through said opening. When either the one-cent or'two-cent key is operated, it will of course be apparent that this zero will be moved out of indicating po- -.Sition' with the movement of the tabletupon which it is carried. When any of the other keys in this cents-bank are operated, this zero-mark of course still remains opposite the sight-opening 55; but since the indicatorplate 43 for the one-cent and the two-cent keys is the farthest toward the rear of the machine in order to connect with its corre sponding bell-crank lever, which is also the farthest to the rear of the machine, as heretofore explained, it will thus be-obvious that the indicator-plates 43 for the other keys of the cents-bank will be in front of the indicator-plate for the one-cent and two-cent keys so that when shifted to the left uponthe operation of an such keys their tablets will move into in icating position in front of the zero-mark upon the one-cent and twocent tablet, thus obscuring this zero-mark from view until these subsequently-operated tablets are returned to normal position in the manner to be described. In the bank of tens 'of cent-keys I have provided a different arrangement for the zero-indicator, comprising a separate and distinct tablet 56, (see Fig. 5,) upon whichis marked a zero, said tablet being mounted upon a sliding frame. 57, which is normally drawn to the right by means of a spring 58, whichholds the zeroindicator normally in view through the si htopening 55. -This frame 57 has forme on its lower side an arm 59, which projects from the front to the rear of the machine across the path of all of the upwardly-extending arms 52 of the tablets of the ten-cent bank, so that when any of said tablets are moved into indicating position their respective arms 52 will contact with said rearwardly-extending arm 59 and force the frame 57 to the left against the'tension of the spring 58, thereby carrying the zero indicator out of indicating position and allowing the other tab- LIL &

let to move into indicating position. it will of course be obvious that no zero indication is necessary upon the dollar-bank. From this construction it will be apparent that if only a key in the dollar-bank is operated its corresponding numeral will be shown at the dollar sight-opening and the two zero-indicators will be shown at the ten sight-opening and the unit sight-opening in the manner shown in Fig. 5 and if only a key in the tensbank is operated nothing will be indicated at the dollar sight-opening. The proper nuineral will be indicated at the ten sight-opening, and the zero of the c nt sight-opening will complete the proper indicaticnj Likewise if only a key in the cents-ha k is operated its corresponding numeral .ill be indicated at the cents sight-opening and a zero would be in position to indicate in the tens sight-opening; but by means of the screen mechanism, to belater described, both this zero and the sight-opening for the dollar hank are obscured, so that only the indication of the cents-numeral remains exposed.

In order to hold the indicator-plates 4 in tne position tp which they are moved, 1 nave provided latching mechanism, as follows: Each of the indicator-plates is' formed with two upwardly-extending projections 60, adapted to be engaged by the nose 61 of the latch 62, fast upon'a shaft 63, suitably journaled in plates extending from the side frames of the machine. This latch is the shape of a bail extending transversely across all of the indicator-plates 43, so that upon the movement of any one of said indicator-plates to the left it will be latched in either one of its indicating positions by means of the engagement of one of the projections 60 with the nose 61 of the latch 62, and a spring 64, engaging an upwardly-extending arm 65, fast to the latch 62, normally tends to hold said latch in engagement with the projection 60. Fast upon the forward outer end of the shaft 63 is a crank-arm 66, to which is attached a downwardly-extending link 67, (see Figs. 2 and 5,) and the lower end of this link 67 is pivoted to a curved lever 68, pivoted to the main frame at 69 and having a rearwardlyextending arm which is drawn downward by a spring 70 and a forwardly-extending arm provided with a nose 72, which engages a cam-disk 73, fast upon the main revolutionshaft 24. It will thus be evident that upon the operation of any key and the consequent rotation of the shaft 24 in the direction of the arrow shown in Fig. 2 the disk 73 will cam the forward arm of the lever 68 downward, thereby operating, through the link 67, to rock the shaft 63, withdraw the nose 61 of the latch 62 from engagement with the projections 60 of any previously-operated indicator-plate, and thus allow said indicator-plates to return to normal position under the spring tension of returning devices to be described, and as soon as the cam-disk 7 3 has rotated far enough to allow the lever 68 to return to normal position the newly-displaced indicatonplates 43 are now in position to have their projections 60 engaged by the latch 62, so that these newly-displaced indicator-plates will now remain in indicating position until the next operation of a key, and, of course, in the manner usual with this class ofmachines, a key in each bank may be simultaneously operated so as to display the complete indication, and all of the indicator-plates will be held latched in this indicating position.

The means for effecting the return of the indicating-plates to normal position when released from the aforesaid latch 62 is shown in 1. At the rear of each group of the afore said bell-crank levers 38 there is mounted upon the upper side of the cross-strip 39 a sliding plate 80, which has extending upward iirofml it a series of projections 81, engaging pins 82, formed on the rear side of the upper arms 40 of the aforesaid bell-crank levers. These plates are formed with slots 80 (in dicated by dotted lines in Fig. 1,) engaged by pins 83, which serve to guide said plates 80 in their lateral shifting movements. Springs 84, one for each plate 86, normally draw said plates toward the right-hand side of the machine, (the left in Fig. 1,) sons to keep the projections 81 in contact with the pins 82. it results from this construction that when any bell-crank lever is rocked in the manner heretofore described to carry its indicatingplate into position to expose its indicatingtablet the pin 82, acting upon the projections 81, will displace the plate 80 laterally against the tension of its spring 84, so that upon the release of the indicator-plate 43 from the latch 62, as heretofore described, the pressure of the projections 81 on the pin 82 causes the return of the bell-crank lever to its normal position, and thereby also carries the indicator-plate 43 to normal position. This arrangement of the plate 80 is of course duplicated for each group of bell-crank levers; but in the dollar-bank in order to return the bell-crank lever correspondin to the nine dollar key I have attachedat the pivotal axis 39 of said bell-crank lever an upwardly-extending L-shaped arm 87, which is bent forward at its outer end 88 in such manner as to bring this outer end into engagement with the projection 81, extending upward from the plate 80 for this bank, whereby upon the rocking of the bell-crank lever of the ninedollar key the L-shaped arm 87 will also rock, and the bent portion 88, acting against the projection 81, and thereby laterally displace the plate 80 against the tension of its spring just as the pins 82 do in the case of the other bell-crap k levers, and thereby effecting the return of the nine-dollar indicating-plate to normal position. This L-shaped arm 87 is used for the nii'ie-dollar key instead of using a projection such as 81 for the other keys on account of the lack of room due to the proximity of the side frame.

Since it is desirable to indicate at the sight openings 56 at the rear of the machine, as well as at the sight-openings 55 at the front of the machine, I have provided mechanism which I shall now describe for effecting this.

' Each of the indicator-plates 43, corresponding to the bank of cents-keys, is provided with two of the tablet-supporting arms previously referred to, one of these arms 52 carrying the tablet with the indicating characters arranged to be exposed at the front sight-opening 55 and the other arm 52 carrying a similar tablet for indicating at the sight-opening 56 at the rear of the machine, and of course at the opposite end of the machine, in order to have the correct order of figures from left to right. The indicatorplate 43 for the one-cent and two-cent keys of the cents-bank is shown in detail in Fig. 4, and it will be observed that the tablet for the front indication bears the zero-mark, as heretofore explained, whereas the tablet for the rear indication bears no zero-mark, the zeromark for this indication being carried upon the 9 tablet for a reason to be explained. As will-be observed also from Figs. 2 and 4, certain of these arms 52 and 52'' do not extend straight upward from the indicatorplate 43, but near their lower ends are bent horizontally at right angles and then again bent upward at right angles. The purpose of this in the cents-bank is to bring the tablets nearer the front sight-opening 55 and also'to permit the insertion back ofthese cents-tablets of the series of dollartablets,whichare of course connected with the upwardlyextending arm 52 of the indicator-plates 43 for the dollar-bank and obviously must be arranged to indicate at the rear opening 56, which is directly opposite the front opening 55 of the cents indication, so as to have the correct indication at the rear from left to right. Since the indicator-plates 43 for the dollar-bank are thus nearest the front of the machine, their respective arms 52 for the back indication are likewise bent laterally, as shown in Fig. 5, so as to bring their respective indicator-tablets near the rear opening 56 and at the same "time slide free of and in the rear of the centsmachine the zero-markmust be placed upon the 9 tablet, which is consequently widened for that purpose, so that the move ment of the cents-tab ets for any amount below nine may bring this tablet in front of the zero-markon the 9 tablet, which of course could not occur if the zero-mark were upon the one-cent and two-cent tablet, as in the case of the front indication, since the one-cent and two-cent tablet is the one which is nearestthe rear of the machine.

In the case of the indication for the tencent bank it will at once be apparent that the same numerals may be used at the back'as at the front of the machine, there being no necessity of any reversal of position, as in the case of the cents or the dollars. Therefore 1 have simply provided my tablets for the tencent bank with duplicate numerals on the front and on the back, the front numerals of course indicating at the front sight-openings 55 and the rear numerals indicating at the rear sight-opening 56. Likewise the zeroindicator for this ten-cent bank, which has been previously described, has a zero-mark upon its rear to show azero-humeral at the rear of the machine.

I will now describe my flash mechanism, the purpose of which is to conceal the indicators upon the initial movement of any of the keys and after the o eration of the key to expose only such of t e indicators as is necessary for a correct reading of the same without the display of unnecessary zeros. This mechanism is shown in Fig. l and domprises separate screen-plates 90, 91, and 92 for each of the three sight-o enings 56 at the rear of the machine-name y, the cents, the dimes, and the dollar openings, respectively. These screen-plates are mounted to slide upon the vertical cross-plate 54, and the plates 90 and 91 have at their tops laterally- \extending arms 93 for the purpose of abutting against the screen-plates next them, and it will thus be obvious that the movement of the screei plate 90 to the left into screening position over the sight-opening 56 will by means of its arm 93 also move the screenplate 91 over its sight-o ening, and the movement of this plate 91 W1 1 by means of its arm 93also move the screen 92 over its sightofpening, and, conversely, the movement of t e screen 92'to reveal its sight-opening will likewise cause the movement of the screens 90 and 91 to reveal their sight-openings; but the movement of the dollar-screen 92 to the left may take place independently of the other two screens and the movement of the screen 91 to the left may take place independently of the screen 90., but will carry with it the screen 92. The screen 90 has attached to its lower side a lever 94, pivoted to the cross-strip 95 at 96, and the lower end of the cross-stri 39 at 104 and a s irin 105 tends to draw the same to the left in such manner as to carry the screen over its corresponding sight-opening. The screen-plate 91 has connected to it a iever 103,-pivoted to connects this lever with the plate 80, which returns the hell-crank levers of the dimeshank to normal position. The screenplate 92 has connected to it a lever 106, pivoted to the cross-strip 39 at 107, and an interme diate portion of this lever there pivoted a bar 108, which is supported by a 100, projecting -from the cross-strip 05, and by means of a slot 110 may have a lateral movement under the influence of a spring 111, the righthand end of which is attached to he plate 80, which returns the hell-crank lovers of the dollar-hank to normal position. rem this construction it results that when cents-hanl-1 is operated and its co ing plate 80 is forced to the rigi'it erring to Fig. l) the spring is put in tension, and obviously through the lever the 1111K 97 and the lever 04; moves the so: to the right, exposing the indie cents-hank. This moveme against the tension. ct s tends to return the screen A ing position. Therefore the spr essarily of greater strength tha; 102. i i hen a key in the dimes erated, the movement or co' plate 80 acts, through the sprim iever 103, and thereby carries 91 to the right, thus er; osing toe noication in the dimes oank, this rnoveine oi the lever 103 being against e tension ci a spring 112, which tends to return said ove the left, so asto carry the screen e 91 normally into screening position. co the movement of the screen-plate 1e right in this manner also moves the con-plate '90 to the right, it results that the spring 105 must be of greater strength tlan the comhined strength of the springs and 112, so as to reveal the indication at both the dimes and the cents hanks. if a key in We dollarbank is operated, the movement oi its corresponding plate 80 acts upon the spring 1 i 1 to pull to the right the bar 108, and thereby pull the lever 106 to the right, thus moving the screen-plate 92 to the right and exposing the dollar indication, and of course the movementv of the screen-plate 92 to right moves both the screen-plates 90 a id to the right, thus exposing their sighwcpenings, and since such movement is the tensionoi both springs 102 and 112 t e spring 111 must also be of greater strengtu than the former two springs combined. nice, as heretofore explained, upon the is: opera explained.

tion, such return of the plates 80 to normal position will release the tension of their res ective springs 101, 105, and 1]. in case tliey have previously been put under tension by the operation of a key in any one of the respective banks, and thereby the springs 102 and 112 will act upon the indicator-plates J0 and 91 to draw the same into concealing position, thereby also moving the screen-plate 92 into concealing position. It will thus he apparent from this construction that at the beginning of operation of any key any of the screen-plates which they have moved into position to reveal its corresponding indicator will he returned to normal screening position. Furthermore, if a lrey in the cents-hank is operated only the screen-plate 90 will be moved into exposing position, the other two screen plates 91 and remaining in concealing position, so that the only figure which shows is thcamount of the cents registration without any confusion fro the presence of superfluous a key in the dimes-hank alone is the screen-plate 91 will he moved into exposing position, as herei the dimes-bank, will of course give the correct indication for the amount of registration; but in such case the screen-plate 02 re mains in concealing position, as heretofore In case a key in the dollar-hank alone is operated its corresponding numeral will he exposed at the dollar-opening by the movement of the screen-piate 92 to the right, which movement carries both the screenplates 00 and 9 1 to the right, thus revealing the zero indications looth in the centshank and in the dimes-hank, making a correct indication the number of dollars registered in the manner in which the figures would ordinarily he written. Of course if a key in each of the several banks is operated simultaneously all of the indicators will be exposed simultaneously in the manner above described with the figures exposed in the correct order and in the manner in which they would ordinarily he written.

in order to provide for the screening and exposing of the indicators at the front of the machine, I have provided a duplicate set of screen-plates 120, 121, and 122 (see Fi s. 5 and 6) for he sight-openings at the tront of the machine, covering the cents-indicators, the dinies, and the dollar indicators, respectively, and in order that the screen-plate 90 may move its corresponding screenirate 120 I have provided a link 123, which connects the horizontal arms 12 1, which extend in- .ward from the screen-plates 90 and 120 and over the rows of indicator-tablets. Like wise oy means or a link 125 the screen-plates ssaszc 92 and 122 are connected to move simultaneously, and by means of a cross-strip 126 the screen-plates 91 and 12]. for the (limes indication are also connected, it being evident that these cross connections are such that upon the movement of any of the rear screen plates into concealing position it will likewise carry in concealing position its corresponding screen-,plate at the front sightopenings.

While the form of mechanism here shown and described is admirablyadapted to fulfil the objects primarily stated, it is to be un-. derstood that I do not care to confine myself to any one form of embodiment of the inven tion here disclosed, for it is-susceptibl'e of em bodiment in various forms all coming within the scope of the claims which follow.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cash-register, the combination with a series ofkeys, of a plurality of indicatingplates therefor, a certain portion of each of which plates bears a plurality of indicating characters; and means connected with the keys for moving into one and the same indicating position common to the entire group of plates the character corresponding to the key depressed.
