CASH-REGISTER.

YSEEGIFICATION forming part of Letters Patent No. 4 19,2455, dated March 31, 1891. Application filed August 15, 1890. Serial filo-362,061. (No model) To (47/) 10. 1.0111, (it 711.10g comm/71..-

Be it known that I, ROBERT E. Nnnsox, .lr., of Columbia, county of Fluvanna, and State of Yirginia, have invented a new and useful Improvement in CaslvHegisters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to w hich it appertains to make and use it, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to an improvement in cash-registers; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

The object of my invention is to construct a cash-register wherein First. The adding and indicating mechanism is normally locked and can only be unlocked by the movement of a key, which in so doing must add and indicate its full value under-all conditions, thus effectually preventing' any tampering with the interna parts should access to them be obtained.

Second. \Yherein over-registration due to momentum of the addingwheels cannot take place, nor can under-registration. It a key be operated quickly or slowly, it is not possible to add a greater or less amount than the value of the key, nor is it possible to indicate a greater or less amount than the amountto beadded. This prevents all errors due to pui'nping" the keys up and down, and also all errors due to a sudden and violent operation of a high-valued key.

Third. .Vherein any number of keys may be actuated simultaneously and the full value of all will be correctly added and indicated. This feature renders all l l0},"-lOCl(S or other devices to prevent two or more keys being operated at the same time unnecessary.

Fourth. llherein if the key is only partially operated the full value will still be correctly added and indicated to the customer. This renders all devices unnecessary which compel a full stroke of a parthilly-operated key.

Fifth. 'W herein the values of all the keys are counted on a single register and indicated at a single opening, so that no addition of the separate amounts at the close of a days business is necessary, nor does the customer have to look at different parts of the machine to see the value of his purchaseindicated. IE$D.9G are indicated, it appears at a single opening in large figures, ($9.96,) and the sum is added at a single opening on the register to the amount previously sold.

A further object of my invention is to so construct the mechanism that when a key is depressed it will be arrested for a brief interval of time previous tothe registration and indication, so that the operator has time to think whether he has depressed the key intended.'

Further objects of my invention will hereinafter appear, and be specifically pointed out in the claims.

Fig. 2 is a vertical transverse sectional view of the same, taken on the line :0 0c of Fig. Fig. 3 is a top plan view of the same, the registering-disks being removed to disclose the subjacent mechanism. Fig. l is a front elevat-ion showing the arrangement of the indicatingalisk. Fig. 5 is a detail side elevation of the registering mechanism. Fig. 6 is a detail view of the trip mechanism. Fig. 7 is a rear elevation showing the indicator-disks. Fig. 8 is a detailviewot' the yoke or lever 26 and the parts coacting' therewith.

The inclosing case A is of any suitable shape and has a drawer B in its bottom provided at its outer side with a knob. A spring 0 is secured to the rear side of the case and bears against the rear side of the drawer to start the latter when the indicating mechanism, presently to be described, is operated.

A longitudinal shaft D is arranged in the case near the front side thereof. This shaft is fixed, and on the same is mounted a series of escapement-wheels 1 l 2 2 3 3 a at 5 5 6 G 7 7 S 8. The

wheels

1, 2, 3, 5, 6, and 7 have each one hundred teeth; the wheels 1., 3, 5, and '7 have each fifty teeth; the wheels 2 6 have each sixly teeth; the wheels 4 8 have each forty teeth, and the wheels 4. 8 have each twenty teeth; also, loose on the shaft D and mounted midway between the respective pairs of escz-tpement-wheels are gear-wheels 1 2' 3 t" 5 (3" 7 8". In each of the said gear-wheels at a suitable distance from its center is mounted an orbital wheel 1 2 3 4 5 6 7 8 respectively, the shafts of the said orbital wheels being arranged radially in the said gear-wheels, and said orbital wheels suitably gearing with spur-teeth a on the pairs of escapement-wheels.

Each escapement-wheel is provided with an escapement-pallet b, pivoted on a support 0 in the case, and having an extended arm (I. A series of finger-keys I are loosely sleeved on the shaftD and arranged on the outer sides of the escapement-wheels, respectively. These finger-keys vary in value from, say, one cent to fifty dollars, as shown in Fig. 3, and have extended counterweighted arms f at their inner ends; or a spring may be substituted. The finger-keys are further provided with tappets 9, adapted to operate their escapementpallets after the keys have been depressed a certain distance, as will hereinafter appear.

The pairs of wheels, the intermediate gears, and the orbital wheels on the shaft D constitute the primary summation-gears. A shaft E is arranged parallel with shaft D and is likewise fixed. A series of pinions 1 2 3 4 5 6 7 b are loosely mounted on the shaftE and mesh with the respective gears 1 2 850., on a shaft D. Pairs of gears 1 2 3 4 5 6 7 8 are loosely mounted on shaft E and connected each to the proximate pinion by a sleeve, as shown in Fig. 3. Gears 1, 2 3, and 4 are loosely mounted on shaft E midway between the pairs of gears aforesaid, and in each of said gears 1 2 3 4. is journaled an orbital wheel 2', which engages the respective pairs of gears. The said pairs of gears,

intermediate gears, and orbital wheels con-' stit-ute the secondary summation-gears.

On a rigid shaft F, parallel with shaft E, are loosely mounted two pairs of gears 1 2 3 4*. Midway between the said pairs of gears are loosely-mounted gears 1 2, carrying orbital wheels m, which mesh with the aforesaid pairs of gears; also, loose on shaft F are pinions 1 2 3 4, which mesh with the gears 1 2 3 49, respectively. Sleeves connect the said pinions to the proximate members of the pairs of gears, as'shown in Fig. 3. The said pairs of gears, together with their intermediate gears and orbital wheel on shaft F, constitute the tertiary summation-gears. On a rigid shaft G, parallel with shaft F, are mounted a pair of gears 1 2, and midway between them is mounted a gear 1 having an orbital wheel 1 which engages said pairs of gears. The latter, the intermediate gear, and its orbital wheel constitute the quaternary summation-gear. A sleeve connects the gear 1 with a pinion 1 that engages the gear 1 and on said sleeve is a miter-wheel 1, having also spur-teeth. A similar sleeve connects the gear 2 with a. pinion 2 that engages the gear2,and on said sleeve is a miterwheel 2, having also spur-teeth. I Apair of horizontal shafts H I at right angles to shaft G extend to the back of the case and are geared to the miter-wheels 1 :2 by miter-wheels 1 2, respectively. A dollarsdisk K is attached to the rear end of shaft H, and a cents-disk L is loosely mounted on said shaft by a sleeve M, which is connected to shaft I by gears N. A cord 0 is coiled on shaft I and has a weight P, the function of which is to return the cents-disk, as will be understood. The dollars-shaft has a similar cord and weight. Clutches R, having serrated crown-teeth, are fixed on the shafts H I, and loosely fitted on said shafts are sliding clutches b, likewise provided with crown-teeth and normally interlocked with the clutches R. The sliding clutches S are provided with peripheral flanges, between which flanges are fitted the endless strap or belt T, which connects said sliding clutches and moves with them in their sliding movements. From the front side of this endless belt or strap projects an arm U, having a depending spur V, with which engages the upper end .of a vertical lever Y.

A trip-bar W is arranged under the fingerkeys, and connected at its ends and center to sleeves on the shaft D by means of arms W. An arm -depends at right angles from the center arm and has a slot W to which is eonnected the front end ofa trip-rod X by a pin X working in the slot. A trip-lever Y, pivoted at y to a suitable support, has its lower end pivoted to the rear end of the trip-rod, and its upper end normally engages the spur V. A tappety is on the lower side of the trip-rod, and a spring-tappet is on the upper side of said rod.

On the upper side of the drawer is a rack 9, which engages a spur-wheel 10, loose on shaft E. A spur-wheel '11 is connected to wheel 10 by a sleeve, and said wheel 11 has an annulus 12 on one side, with a'space or notch 13, adapted to be engaged by the spring tappet y A wheel 15, Fig, 2, is loose on shaft F, near the wheel 14, and inside the rim of wheel 17, and is connected by means'of a sleeve .to a spur-wheel 16, that meshes with the wheel 1 of the quaternary snmma'tiom gear.

A wheel 17, loosely mounted on the shaft F, between the wheels 14 15, has an annular rim 18, that projects laterally over the wheel 15, so that the latter is concealed. On the inner side of this rim are serrated teeth 19, engaged by a spring-pressed pawl 20 on the wheel 15. This enables both wheels to move together in one direction, and enables one to move independently of the other in the reverse direction. The wheel 17 has a-tooth 21 on one side,adapted to be engaged by a springpressed pawl 22, pivoted to'the wheel 14.

A cord 23 is coiled on the rim of the wheel 17, Figs. 2 and 3, and from the free'end of the cord depends a weight 24. This wheel 17 being connected by pawl 20, wheel 15, and wheel 16 to the quaternary summation-gear, which is connected to the tertiary summation-gears, and those in turn connected to the secondary IIO summation-gears, which mesh with the primary summation-gears. it follows that the weight tends to turn all of the escapementwheels in the direction of the arrow in Fig. 1. The escapement-pallets being normally engaged with the escapement-wheels, keep the trains of gearor transmitting mechanism normally at rest and locked.

Coiled springs 25 are fitted on the shafts H I, and they bear at one end against suitable collars or pins on the shaft, and at their opposite ends they operate against the sliding clutches S, and said springs tend to keep the sliding clutches in engagement with the fixed clutches R, which serve as stops to arrest the axial rotation of the shafts II I, and also limit the rearward movement of the sliding clutches S. The shafts H and I are broken between the clutches S and B, so that the clutches R, which are nearest the indicators, can revolve independently of the clutches S, which are nearest the keys, and this happens each time the indicators are reset to zero, as will hereinafter appear. The clutches S, which are splined on the longer parts of the shafts H I, after being moved out of engagement with the clutches R, might become caught, and after being released from the lever Y might fail to re-engage the clutches It, in which case the register would fail to revolve the indicators after being actuated. To obviate this I provide what. I term a shoving device or yoke lever26, Figs. 1, 2, and S, which consists of apivoted yke-lever having the arms 26, adapted to bear against the clutches S, the cross-bar 26", connecting the two arms 26, and the pivots 27, which may be fitted into any suitable support (not shown) attached to v the frame of the machine.

Suitably attached to the lever Y is a rod 27, working in suitable guides and provided at its end with a spring-pressed pawl 29, which can onlyturn on its pivot when rod 27 is moving toward the indicators K L. Rod 27 is also provided on its under side with a depending tappet-pin 28, Figs. 1 and 2, which takes against the cross-bar and turns the shoving device on its pivots 27, when the rod 27 is moved toward the keys. One pawl 29 is sufficient; but I prefer to use two, Fig. 6, in which case I connect them in any suitable manner, so that they may always move together. These pawls are adapted to pass through notches 30, cut through the rim or flange of the non-sliding clutches R on the short ends of the shafts II I. From this construction it will be seen that upon the depression of a key the lever Y will be turned on its pivot, carrying with it. the rod 27, the arm U, strap T, and clutches S, thus disengaging the register from the indicators. \Vheu the upper end of lever Y reaches the dotted-line position of spur V, (shown in Fig. 1,) it will become disengaged therefrom, and tappet 28 on rod 27 being so placed that it will at this point strike cross-bar 26" the yoke-levers 26 will turn on their pivots 27 and their upper ends will shove the clutches S back into engagement with the clutches R, as shown in dotted lines, Fig. 1.

It being understood that the drawing in Fig. 8 is somewhat exaggerated for clearness and that it does not show the rod 27 and pawls 20, if the clutches S should become caught the longitudinal motion of rod 27 is stopped, as is also the lever Y and bar Wand operating-key.

\Veights P are provided for automatically returning the indicators K L whenever clutches S R are disengaged. These weights are automatically rewound every time the register operates the indicator-disks. When this happens, the clutches S R are turned together, the former revolving in the strap or band T, which is kept from turning by any suitable attachment to a fixed part of the frame, (not shown)-for instance, the same part which supports the y0ke-lever or shoving device 20. Thepower for operating these parts is supplied from the heavier weight 24, which is wound up by the drawer, as previously described. When a keyis depressed and rod 27 begins to move toward the keys the pawl 29 takes against the flange of clutcli R and stops the downward motion of the key' but clutches SR being disengaged the weights P return the indicators to zero, when the pawl or pawls 29 will pass through the notches or slots 30 in said flanges and the further movement of the key and re-engagement of clutches S R takes place. The tappets g on the finger-keys are of such a length that the escapement will not be operated until just before the key completes its downward stroke and after the shoving device 26 has re-engaged the clutches S It, so that no registration can take place while said clutches or while the registers and indicators are disengaged. After the key is released all parts return to the position shown in Fig. 1 through the action of the weightsf or any other suit able means. Arm U having a slight sprin in it, lever Y automatically re-engages spuI' V. A bell-crank lever 31 is pivoted to a suitable support in the frame and has its vertical arm arranged in the path of the trip-rod. A bolt 32 is pivoted to the horizontal arm of the bell-crank lever and passes through a keeper 33 and normally engages a notch 34 in the drawer to keep the latter locked when closed. A bell 35 is mounted in the case and has a pivoted hammer 36, provided with a spring pressed tappet 37 at its upper end adapted to be engaged by the tappeton the lower side of the trip-rod when the latter is returning to its normal position, as will appear hereinafter.

A registering mechanism consisting of a series of gears is mounted on shafts 58 and 30, arranged parallel and vertically above the shaft G. This registering mechanism, Fi s. 3 and 5, consists of the wheels 1 2 QQEHITIEI respectively into the pinions R R". The pinion R is connected to the wheel R and both are loosely mounted on the shaft 38. The

shaft 39. To the pinion R is sleeved the pin-.

ion R also loosely mounted on shaft 39 and having a single teeth, which meshes with the registering-wheel R on shaft 38. The registering-wheels R and R are connected by the loosely mo'unted wheel P carrying an orbital wheel P to thepinion R which is sleeved to the single-toothed pinion R both loosely mounted on shaft 39, and the single tooth of pinion of R gearing into registering-wheel R which also gears into pinion R, which is sleeved to pinion R carrying a single tooth, which gears into registering-wheel R, which wheel R also gears into pinion R and so on, itbeing seen that the pinions and wheels are all loosely mounted on their shafts and that when the registering-wheel R makes a full revolution or half -revolution or a quarterrevolution, according to the diameters of the pinion on shaft 39, its tens will be carried to the registering wheel R and as the registering-wheel R turns it will turn the wheel P It will also be seen that the wheel 2, through register-wheel R also turns wheel P, which wheel P thus sums up correctly the angular movements of wheels 1 and 2", whether-the latter be actuated simultaneously or successively, and that the summations on the wheel P will be carried successively to the registerwheels R R 820., so that the register will inrlicate at a single opening units, tens, hundreds, thousands, duo.

The operation of my invention so far is as follows: When a finger=key, say the value of one cent, is depressed, it trips the escapementpalleton the wheel 1 and the said wheel turns through the space of one tooth by means of the weight 2& and the gears, as follows: The primary escapement-wheel 1 turns its orbital wheel 1, which, the primary wheel 1 being locked by its escapement-detent, revolves on its axis and moves on the gear attached to said wheel 1 as a track, thus turning the wheel 1 half the angular value of one tooth on wheel 1. The pinion 1 being half the diameter of wheel 1 causes wheel 1 to turn the full angular value of one tooth of wheel 1. The wheel 1 likewise turns wheel 1 half the angular value of one tooth on Wheel 1. Pinion 1, being half the diameter of wheel 1", turns wheel 1 the full value of one tooth on said primary wheel 1. Likewise through orbital wheels m, pinion 1, of half the diameter of wheel 1, the'wheel 1 is turned the full value of one tooth on said primary wheel 1. Wheel 1 is of same diameter as wheel 1, as shown, and turns, through the clutches S and gears N, the cents-indicator wheel the full angular value of one tooth on said primary wheel 1. The cents-indicator is divided into'one hundred spaces, and marked from zero to 99,the primary wheel, having one hundred teeth, the angular value of one tooth through which it has been turned will cause the indicator to show one cent. Likewise if the two-cent key should be depressed, its es- 2 Hence the motion transmitted to wheel 2 v is multiplied to three times the value of one tooth on the primary wheel 1. Hence through the train of gears described the indicator whl be turned to show three cents. In the same manner the five-cent, ten-cent, twenty-cent, twenty-five cent, fifty-cent, one-dollar, twodollar, three dollar, five dollar, ten dollar, twenty-dollar, twenty-five dollar, and fiftydollar escapementwheels and their connecting pinions are so proportioned that in each instance their indicating-disks will show the correct value of the operated key or keys. It will be seen that if both the one-cent and two-cent keys are simultaneously operated the orbital wheel t' will cause the wheel 1 to transmit to wheel 1 the full value of both keys, and if any number of keys are operated simultaneously or successively the full value'of all of such keys will be correctly transmitted to wheels 1 or 2, as the case may be; and it follows that such value will be correctly indicated on the indicatingdisk..

Wheels 1 and 2, gearing into the dollar and cents wheels of the register, as described, their full value will be registered, and it will be seen that is immaterial whether such keys are depressed simultaneously or successively, since the register is capable of summing up in either case the correct value through the transmitting mechanism just described. It will also be seen that the same part of such transmitting mechanism that operates the register also operates the indicator, so that it is not possible to indicate a greater or lesser amount than is registered. It will also be seen that said transmitting mechanism, as well as the indicator and register, is normally looked through the escapement detents, thus rendering it impossible to move the register backward or forward, except through the operation of the key, and momentum is impossible. A suitable key or zero-setting mechanism is to be used with the register to reset it to zero when desired; but such mechanism, being well known in the art, is neither shown nor described here. At the initial depression of the key the trip bar W moves with it, and the arm W forces the trip-rod Y rearward, and the trip-rod operates the bell-crank lever 31 and causes the bolt to unlock the drawer, as represented by dotted lines in Fig. 1. As the drawer moves forward, the rack 9 turns Wheel 10, and wheel 11, being connected to wheel 10 by a sleeve, also turns, and the wheel 14:, meshing with wheel 11, turns with it, the pawl 22 slipping loosely over the rim 18 of wheel 17 Inasmuch as the escapement-pallet permitted the wheel 1 to turn through only the space of one tooth, the weight and cord on wheel 17 causes the latter to turn through the angular distance equivalent to the value of the key, and the pawl 20 caused the wheel 15 to move a corresponding distance in the same direction with the wheel 17, thereby moving the stop or tooth 21 on the wheel 17 to a position equal to the value of the key. Inasmuch as the shafts II I are connected by gears to the primary gears of the indicating mechanism, the motion of the wheel 16, connected to wheel 15, was transmitted to the wheel 1 and consequently the wheel 1", retainingits engagement with wheel 2, did not affect the latter, but caused the wheel 1" to turn one space, and with it the various transmitting or summation mechanism back to primary wheel I. It will be understood that the indicator showing an amountsay $l.50 the rearward movement of the trip-rod heretotore described causes the upper end of the lever to move forward, and being in engagement with the strap T, connecting the clutches moves the latter forward out of engagement with the stops or clutches R on the disk-shafts. Hence the latter will be free to turn under the influence of their weights, back to zero positions or any other predetermined position, the said position being determined by a notch in the flange of the stops, Fig. 6, presently to be described. \Vhile the trip-lever is thus moving and before reaching the full limit of its stroke, the pawl 29 on bar 27 strikes against the flanges 30' of the stops, and thus arrests the motion of the bar TV. The contact of the pawl 29 with flange 30 continues until the notch 30 in flange 30 comes opposite pawl 29, when the pawl slips through said notch and the movement of trip-lever continues. Atthis point the pin or bar 28 strikes the yoke or pivoted lever 26, causing it to turn on the pivot, shoving the clutch back into engage ment, the trip-bar in the meantime having become disengaged from said clutches. The movement of the trip-bar continues until, through the shoving device consisting of the pin 28 and yoke-lever 26, the clutches are in engagementwith the stops. When this takes place, the drawer is released and the escape ment mechanism is operated and registration and indication takes place, after which the bell is rung. Yoke-lever 26, it being understood, operates the clutches for both indica tors, resetting them to zero. It will be seen that the arresting of the pawl 29 against flange 30 causes the key to be arrested in its (ilownward motion until the indicators are reset by their weights and the pawl can pass through the notch above described, at which time the indicators are at zero. This allows the operator time to thinkit hehas depressed the key intended, and if he has not, since no registration has taken place, the tappets on the keys being at some distance from the es capement-detents, he may depress the proper key; also, since bar 26 has insured the re-engagement of the clutches (helped by springs) l before the registration takes place, the indication is compcllcd to be correct. As the drawer opens and immediately after the registering mechanism has been operated, as hereinbefore described, the notch of the annulus wheel engages the springtappet Y of the trip-rod, and thereby restores the latter, the trip-lever, and the trip-bar \V to their initial positionsand ringing thebell. (Showninsolid lines in Figs. 1 and 2.) \Vhen the drawer is closed, the rack 0 and wheels 10 11 cause the wheel 11- to reverse its rotary motion and the pawl 22, by engaging the stop or teeth 21 of wheel 17, moves the latter wheel an angular distance corresponding to the value of the key or keys operated, and hence raises the weight to the position it formerly occupied.

From the foregoing it will be understood that whenever the d awer is closed after a key, no matter of what value, has been operated the weight will be restored to its initial position, and hence never runs down. This power mechanism being geared to the drawer, the tooth or stop 21 in wheel 17 being in err gagei'nent with pawl 22 when the drawer is closed, it will be seen thatthe action of weight is taken off said power mechanism and it is then rendered inactive, so that as long as the drawer is closed if any key were operated no power could be transmitted to the escape ment or transmitting mechanism, and hence no registration or indication could take place without first opening the drawer a predetermined distance. It will also be seen that when the keys are returned to their normal position when the drawer is open all thekeys are looked through annulus 1t and tappetzf and bar W.
