EUGENE E. BARTLETT, OF SPRINGFIELD, MASSACHUSETTS.

CASH REGISTER AND INDICATOR.

SPEGIFICATION forming part of Letters Patent N0. 470,463, dated March 8, 1892.

Application filed October 19, 1891- Serial No. 409,183. (No model.)

To all 1072,0721 it may concern:

Be it known that I, EUGENE E. BARTLETT, a citizen of the United. States, residing at Springfield, in the county of IIampden and State of Massachusetts, have invented new and useful Improvements in Cash Registers and Indicators, of which the following is a specification.

The object of this invention is to improve the construction of cash registers and indicators, whereby the machine will be comparatively simple and at the same time have a capacity for recording any amounts, as desired, within a wide range.

It is the object, furthermore, to provide a construction of register whereby the aggregate of amounts which may have been indicated from time to time may be seen on a mere inspection and without requiring any computations.

This invention consists in the construction and combination of parts and devices, all substantially as will hereinafter more fully appear, and be set forth in the claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a perspective view of the machine. Fig. 2 is a front view with the front wall of the casing removed and some of the internal parts shown as broken away for the purpose of clearness of illustration. Fig. 3 is a plan and horizontal sectional view on line 3 3 of Fig. 2, certain parts being shownin full lines. Fig. 4: is a cross-sectional elevation of the machine. Fig. 5 is a horizontal sectional view, on an enlarged scale, taken on line 5 5, Fig. 4. Fig. (i is a representation by diagram of the gearing for the register.

In this machine there are three groups of mechanism A, B, and 0, each of which is act-uated by the movement of a key to indicate a greater or smaller sum, the actuation of one of the mechanisms indicating cents, the next tens of cents, and the next dollars.

The register comprises a dial regularly graduated with a hundred divisional marks, with indicating-figures up to a hundred in a circle thereon, and there are three hands, one for indicating cents on the register, the other for indicating dollars up to hundreds, and the third for indicating by steps of hundreds of dollars up to ten thousand dollars. The mechanism A contributes to the operation of the one B, and likewise the one B to the one C, so that notifications of the registering capacity of a lower mechanism may be absorbed in a corresponding change of position for register-.

ing of the next higher mechanism. The actuation of each of the mechanisms operates the register (indicated atD) to record a corresponding sum to that indicated at such actuation, and the operation of each and any of the mechanisms for one or the other orders of cash-indication, as the case may be, while respectively having its due effect on the register, will be without effect on the indicating mechanism for a higher or lower order.

I will proceed to describe the machine more in detail. E represents a vertical supportingframe within the casing, having mounted thereon three arbors a, b, and 0. Each arbor has loosely thereon a pinion 10, with each of which respectively engages a vertically-movable rack-bar 12. Each rack-bar may be vertically moved to any extent to cause a rotational movement of the pinion which it engages to the extent of one or more of all of its teeth by means as follows: Each rack-bar rests upon the rear end of a lever 13, which is a rearwardly-extended part of oneof the stirrupframes a or 0 Each stirrup is mounted on the horizontal rod 14 and is normally held with its forward portion elevated (its rear being depressed) by the spiral spring 15.

f represents a key-lever, which has its hub adapted to slide freely on the horizontal rod 16 from end to end of the machine, the said key-lever being forwardly projected and extended through an aperture 17 in the front of the casin g. The key-lever on being depressed will depress the one or the other of the said stirrup-frames over which it may be slid, and in order that the amount of key-depression, as desired, may be determined there is in front of all of the said stirrup-frames the horizontal bar 6, which has slots 19 therein, which open to the top of the bar and which are arranged in three sets graduated as to depth, as particularly indicated in Fig. 2. If it is desired to rotate pinion on the arbor a to indicate five cents,the key is slid over the fifth slot from the right-hand end of bar 6 and then forced to the bottom of said slot, and so on.

There is provided at the rear of the machine and the shaft.

- ratchet 20, formed as one with the pinions onthe other arbors a and c, is made, a springpressed pawl being respectively provided therefor. The pawl for operating on the tooth pinion 42.

the series of rods 2', which are tobe vertically guided, each carrying at its upper end the indicating-tagj and the key-lever has a downwardly and rearwardly extended arm k, which is adapted to come under the lower end of the indicator-rod,which corresponds totheamount to be indicated and recorded when the keylever is brought to such position of engagement. Each of the rods 1' has a detent-spring m, as shown in Fig. 4, which as the rod is lifted is inwardly forced, permitting its passage by the top bar n, Which-is a horizontal member of a stirrup-like frame G, the said frame being by the vertical members n thereof intermediatelypivotally hung, as indicated at u atv the ends of the casing. The said frame is capable of a forward and backward swinging movement, being retained in its vertical position, as shown, by the spring 0. One, two, or three of the indicating-tags having been raised in succession to indicate the amount of a purchase (which may, for instance, be eight dollars and thirty three cents, as shown in the drawings) and performed by depressing the key-lever at the eighth slot of the left-hand or dollar series in the bar 6, then moving the key-lever for depression at the slot of third depth at the middle or dime series, and again at the third slot in the right-hand or cent series, and it is desired to restore them to. the lower positions in readiness for the next operation, the frame G has its upper portion forwardly swung by means of the push-rod q, extended to the front of the casing, and then the said top bar n of the-frame G will be removed from its position of support relative to the spring-detents m and the indicators will fall. Each arbor a, b, and c has, as an extended hub of the ten-tooth pinion 10, each of which is loose on the arbor, a ratchet-wheel 20. The arborb is forwardly extended through the dial and carries at its outer end the hand :n'for showing cents on the register. There is fixed on this arbor I), back of the ratchet-wheel 20, a hundred-tooth spur-gear 40, and on the hub thereof a ten-tooth pinion 45. On the face of this spur-gear 40 there is provided a spring-pawl 44, which takes into the teeth of said ratchet on the arbor b. The arbor I) also has toward its forward end and fixed. thereon the ten- The movement of the rack 12 upwardly will, owing to the engagement which it has with the pinion 10 and the medium of connection constituted by the ratchetwheel 20, fixed to the pinion, and the pawl engagement between the said ratchet-wheel and the gear 40, cause a rotation of such gear As the rack descends the ratchet-wheel may turn around free with the pinion without effecting any rotational movement of the arb0r,the ratchet-teeth then slipping past the pawl. A similar provision of ratchet which is mounted on the arbora is carried on the disk 46, which is fixed on the arbor a, while the pawl foracting on the ratchetwhich is mounted on the arbor c is carried on the face of the hundred-tooth gear 5O, which is fixed on the said arbor c.

The arbor a has toward its rear end a fixed tentooth pinion 55 and also loosely mounted on its forward end the hundred-tooth spur-gear 43, which meshes wit-h the pinion 42 on the arbor b, and the'said gear-wheel 43 has as one therewith the ten-tooth pinion 52. The pinion 52 meshes with the gear-wheel 53, which is carried on a sleeve 54, which surrounds the arbor b- The sleeve 54 has thereon next to the spur-gear 53 the pinion 56, and this pinion meshes with a hundred-tooth gear 57,

which is loosely mounted on the arbor c, and this latter gear has on its hub the ten-tooth pinion 58.

To showthe registration'by the hands onthe register-dial of the amounts of each operation of the key-lever, which are separately shown by the indicator-tags j, it will be assumed that the key-lever f is carried into the fifth slot 19, counting, from the right, when the five-tag will be thrown up and the pinion 10 on the arbor a will be rotated to the extent of five teeth, correspondingly turning the arbor a and the pinion '55. The pinion 55,

gearing into the hundred-tooth spur-wheel 40, causes this to rotate to the extent of five teeth, or one-twentieth of a rotation, when the hand w for cents will be turned five points on the dial. Should it be desired to operate the machine to show fi ty cents, the key-lever f is moved to the fifth slot in the middle series on the hand y, which shows dollars on the register-dia], will move for a distance corresponding to half that of one of the hundredth divisions on the dial. The last operation repeated would indicate another fifty cents, and

- the balance of the hundredth division would be passed, showing, of course, a dollar-registry.

In the operation last described the arbor I), being rotated to the extent of half a turn,

. causes the cents-hand 0c thereon to be carried half-way round the dial, thereby positively pointing off to be readily seen the fifty cents. To show the registration by the pointer or hand 2' of a part of one of the hundredth divisional spaces on the dial,it will be assumed that the five-dollar sale has been made and indicated by moving the key-leverto the fifth slot in the left-hand series of the bar e and .of the arbor 0.

depressed. This will insure a half a rotation The spur-wheel 50 will be turned half around, causing five rotations of the pinion 45 and also pinion 42. \Vheel 43 will be therefore caused half of a rotation, and with it pinion 52, which will cause wheel 53 and sleeve 54: on e-twentieth of a rotation, the dollar-hand y therefore moving five points on the dial to positively register five dollars. This twentieth of a rotation of wheel 53 being communicated through pinion 56 to the spurwheel 57 will cause the latter to rotate to the extent of one two-hundreth of a rotation and the spur-wheel 59 on the sleeve 60 by means of wheel 58 will have a one two-thousandth of a rotation, the hand .2 having a movement corresponding to one-twentieth of the distance of one of the hundredth divisional spaces on the dial, of which said hand indicates them as hundreds of dollars, and said one-twentieth of that divisional space will therefore correspond to the five dollars. In reading the registry at the dial each divisional space is to be counted which is at or next to the left of the point of the hand, and therefore if after the machine has been operated to make a number of sales, as, for a days business, which may amount to seven hundred and ninety-four dollars and thirty-three cents, the pointer will be to the right of the 7 0n the dial and almost up to the 8. The hand 1 will be just past the 94, being about a third of the distance beyond the 94 mark toward the 95 mark, and the hand as will point to 33. The hands, as indicated in the enlarged horizontal sectional view, Fig. 5,have sleeves, which set the one on the arbor Z) and the others on the sleeves 5i and 60, respectively, therefor by friction, so that as said sleeves or the arbor are moved the hands will move therewith and yet on desiring to set all the hands ,at zero relative to the dial to commence a new period of registry the same may be readily turned back, as common with the hands of a clock. A cash-drawer K is provided and is held closed by the pivoted latch s on the lever-arm it. As the lever-arm is upwardly swung on the depression of the key f the latch is removed from its restraining engage ment relative to the drawer, when the latter may be thrown forward by the spring r.
