Application filed January 2, 1339- Serial No. 295.137. (No model.) 7
To all whom it may concern:
Be it known that I, JEROME J. WEBSTER, a subject of Victoria, Queen of the United Kingdom of Great- Britain and Ireland, residing at Somerville, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and usefullmprovement in Cash Indicators and Registers, of which the following is a specification.
My invention relates to cash indicators and registers; and it consists in the devices and combinations hereinafter described and claimed, and which have for their object to indicate on both sides of the machine the amount registered by a single operation of the machine, to retain the indicating-numbers exposed to view after any operation of the machine until the next operation thereof, to prevent the simultaneous depression of two or more keys, to prevent a partially -depressed key from returning to its normal position until after its complete depression, and to indicate bythe depression of asinglekey units on one indicating-wheel and tens on another-indicatingwheel; also, in a series of registering-wheels, each adapted to register ten and to cause by a esmplete revolution of any Wheel the wheel registering numbers of the next highest denomination to make one-tenth of a revolution, to enable in such a series of registering-wheels each of said wheels to be operated independently to register numbers of its own denomination and also to operate the Wheel that registers numbers of the next higher denomination and to retard the operation of the registering-wheel of the higher denomination due to the action of the registering-wheel of the next 10 wer denomination until its independent operation has been completed, to keep the drawer normally locked and to prevent it from being opened except by the operation of the keys, and to prevent the keys and the indicating and registering mechanism from being operated when the drawer is open.

' The case A consists of a lower rectangular part a, in which slides a till or drawer D, the table a or top of the part a, supporting the operating mechanism of the indicator and register, and an upper portion a which conceals said operative mechanism. The drawer when released is caused to protrude from the case by a drawer-opening spring cl, the abovenamed parts being of any usual construction, except that the upper part of the case is preferably shaped to conform partially to the actual requirements of the space occupied by the operating mechanism. The keys K turn upon a fulcrum-rod 70, supported by two or more brackets or posts secured to the table to of the case A in substantially the usual manner.
The keys, as in other indicating-machines, may be arranged in convenient groups, one to be employed in registering and indicating cents, another group to be used in registering and indicating dimes or dollars, and so on,the keys being numbered to correspond to signals which are brought into view by the depression of the keys. The keys K all have a uniform range of motion and in the drawings are numbered from 5 to 95 in multiples of five, the key K at the extreme right being intended not for registeringpurposes, but merely to unlock the drawer, sound the alarm, and return the signals to 0, as hereinafter more fully explained. Every other key K (beginning at the right and excluding the non-indicating key K) is marked 5 or some number represented in part by a 5 in the units-place, and the alternate keys are marked 10 or some multiple thereof.
The rocking plate P is provided with arms 19, through which the fulcrum-rod is passed, the plate extending over all the keys of the group and in its normal position being ar ranged just above the keys of said group, so that the depression of any key to its fullest extent will cause said rocking plate to turn upon the fulcrum-rod 7t,a spring 19 restoring the rocking plate to its normal position when the key has returned to its position.
On the under side of the rocking plate P,in brackets 13 11 one of said brackets 19 being a rib which extends along the left side of said rocking plate, slide nine actuating and stop bolts p arranged in a common plane, said bolts being parallel both with the top of said rocking plate and with the fulcrum-rod 7c, the left ends of these bolts p being held flush with the left side of said plate P by springs p attached to said bolts and to the under side of said plate, and by stops or shoulders 19 on said bolts, which limit the motion of said bolts to the right. Although, as above stated, the complete depression of any key one of which is marked by a number, which is 10 or a multiple thereof, and the other by a number greater than said multiple by five, as 10 and 20 and 25, or
90 and 95, the inclines 11 19 being so arranged that the depression of either of the keys of such pair and the raising of the rear arm of said key against one of the inclines will cause the bolt to which said inclines are secured to project from the left of the rocking plate an equal distance, and one of the bolts 19 will thus be caused to project from the rocking plate by the depression of any key numbered higher than five. Each of the bolts 11 projected enters a horizontal slot Zin the right side of a registering-lever L, arranged at right angles to said bolts and turning upon a horizontal fulcrum parallel to the fulcrum-rod back of said keys, said slot being long enough to admit the ends of all of said bolts at a time and wide enough vertically to admit them freely, but without allowing them any vertical play therein. It will be seen that slightly depressing two nonadjacent keys will cause two bolts to enter the slot Z in the registering-lever L; but, the rocking plate and registering-lever having their fulcrums at some distance from each other and rising in opposite directions and the bolts lying in the same horizontal plane and fitting said slot, it is evident that neither the rocking plate nor the registering-lever can be raised when two bolts are in the slot Z, and therefore two corresponding keys arranged under the rocking plate cannot be completely depressed. It follows that only two keys of the same pair-that is, two keys whichoperate the same bolt-can be simultaneously depressed to their fullest extent and two keys of the same pair cannot be depressed, except by intention, because, as will be seen in Fig. 3, every two keys of the same pair are arranged in different ranks, the keys denoting 10 and multiples thereof being in the front rank and the keys denoting 5 and odd multiples thereof being in the rear rank, and the buttons of the two ranks are some distance apart. It will appear hereinafter that when two keys of the same pair are depressed the indication and registration due to the key bearing the higher number only will be accomplished. For anything that appears thus far the depression of either of the keys of the same pair would accomplish the same results, and so far as their action upon the registering-lever is concerned this is true, the keys of each pair from right to left moving the registering-lever through a greater are than the keys of the pair next to the right thereof, because the bolt operated by the keys of the lower pair is nearest to the fulcrum of the rocking plate, and therefore swings through the smallest arcand also acts upon the registering-lever at a greater distance from the fulcrum of said lever, the bolts operated by the successive pairs of keys being placed at greater distances from the fulcrum-rod as the successive pairs are farther from the right of the rocking plate, as shown in Fig. 8.
The indication and registration due to the movement of the registering-lever are always 10 or multiples thereof, other means, hereinafter described, being used to indicate and register 5 and odd multiples thereof.
To the registering-lever L, concentric there with, is secured a toothed are or segmental gear Z which engages a mutilated pinion Z turning loosely on a stationary horizontal shaft Z (see Figs. 1, 4, 10 to 14, 18 to 20, and 22 to 24) and secured to a transfer wheel or gear Z A pawl Z ispivoted on the side of the transfer-wheel Z and engages the tooth 't' of a single-toothed ratchet-wheel t", which, together with the mutilated or long-toothed ratchet-wheel 2' and the cam-wheelt' ,is rigidly secured on the hub of the indicating-wheel I, so that depressing a key and raising the registering-lever causes all said wheels I t i 2' to be rotated together.
The indicating-wheel I is provided on its face with two sets of figures i, from 0 to 9, inclusive, (see Figs. 2 and 3,) the same figures of the two sets being diametrically opposite each other-that is, one 0 is opposite the other 0 and one 9 is opposite the other 9, and so of the intermediate figuresand said wheel I in its normal position, or before the machine is operated, displays through each of the windows 0, a in the case -A the figure O at the front and back of said case. When any key numbered 10 or more is depressed the indicating-wheel I is turned to display at said Windows a figure which is the same as the figure which occupies the tensplace on said key. Thus if the 10 or 15 key is completely depressed the figure 1 appears at the windows; if the or key is depressed the figure 8 is displayed, and said indicating-wheel is held from returning to its normal or 0 position by a pawl i which being pressed by the spring i engages the proper tooth of the ten teeth of the muti lated or long-toothed ratchet-wheel 2' the pawl Z, the transfer-wheel Z which carries it, and the pinion Z returning to their normal position when the key is let go and the rocking plate and registering-lever return to position.
lhe units-indicating wheel 1 consists in effect of two opposite sectors t of a wheel, the face of each sector showing a O and a 5, the diametrically-opposite figures being alike, and 0 being normally displayed at each of the windows a (L6 in the front and back of the case.
Sliding in brackets or ribs 19 p at the op- IIO posite sides of the rocking plate is a unitsbolt 19, provided with as many inclines or cams p as there are keys denoting odd multiples of five, these in clinesp being arranged over said keys, so that when any such key is depressed and its rear arm strikes said incline said units-bolt is moved, preferably, in a direction opposite to that of the bolts 1)", above described, in order to equalize the pressure of the inclines 19 29 on the keys. The units-bolt p is provided with a backward projection 19, which when said boltis moved, as above described, is brought under a lever i pivoted at its front end at i to the frame of the machine and at its rear end connected by a link 1' to the units-indicating wheel back of its center, so that when the rocking plate is raised by the complete depression of a key marked with any odd multiple of five the projection 19 strikes the lever i and turns the units-indicating wheel far enough to display the 5 marked thereon. Thus when the key marked 85 is depressed the S is shown on the tens-indicating wheel I and the 5 in the units-wheel I. The tens-indicating wheel I is prevented from turning too far and thereby showing too high a number by a bell-crank lever i which turns on a horizontal pivot W, the upper end of said lever i having a backwardly-projecting tooth 2', which enters one of a series of notches 2' in the face of said wheel when the rocking plate strikes the lower arm of said lever and is disengaged from said notch i when said plate falls by a spring 1', wound around said pivot and pressing upon said lower arm, there being as many notches i as there are figures on one-half of said wheel Ithat is, ten notches.
The indicating-wheels I I continue to show the indicatingfigures after the same are once displayed until another depression of the same or another key. The first effect of such second depression is to allow both of said indicating-wheels to return to their normal positionthat is, to the position in which is indicated at each of the windows. Until the tens-indicating wheel I is so restored to the 0 position, the registering-lever L is prevented from operating by the unlockinglever "6 which turns on the horizontal rod 1' supported on the frame of the machine, the lower end of said unlocking-lever being forced by the spring Z backward over a lateral projection Z whenever the registering-lever is in its lowest position; but when said tens-indicating wheel is in the O posit-ion a cam proj ection on the cam-wheel 2 (said cam-wheel being, as above stated, secured to the hub of the tens-indicating wheel) presses against the upper arm of said unlocking-lever and turns the lower end of said unlocking-lever forward out of the way of the projection Z and allows the registering-lever to rise.
The retaining of the indicating-wheels in the indicating position is accomplished by means of pawls 11 one of which engages the teeth of the long-toothed ratchet-wheel 2*, as above stated, (see Fig. 12,) and the other i of which engages a two-toothed ratchet i secured to the hub of the units-indicating wheel Z, these pawls '6 being held in engagement with their respective ratchets by a spring i, (shown in Fig. 14,) supported on the frame and pressing agai nst both of said pawls. The pawls 1' 1' are pivoted on the abovenamed rod t, which also serves as a fulcrum for the pawl-lever t and unites both of said pawls i to said pawl-lever, by a rule-joint such that a forward motion of the lower end of said pawl-lever causes the upper ends of both of said pawls to be thrown out of engagement with the teeth of their respective ratchets, and said pawls are held out of such engagement by lateral projections 1 1 on said pawls, respectively passing over ribs 1? 2' on the free ends of spring-latches 6 i supported on a bracket 1' secured on the frame of the machine and supporting the rod 2', until said pawls are again thrown into such engagement by the long teeth of their respective ratchets when the indicating-wheels are returned to their 0 indicating positions, said long teeth being too long to pass by said pawls, and thereby preventing the indicating wheels when returning to position from passing their O-indicating positions.
The rear end of each key K K is provided with a projecting finger 70 which when the key is depressed rises against a releasingplate J, (or a series of rigidly-connected fingers, one for each key, would accomplish the same purpose,) rigidly secured to the releasing-rod j which extends back of all the keys and turns in brackets j, secured to the table a, there being secured to said releasing-rodj a lever J, bearing a leaf-spring j, which curves upward and backward and has at its upper end a lateral earj', (see Figs. 1, 2, 4t, 12, and 12%) which strikes a horizontal stud 2' projecting from the lower end of said pawl-lever i and throws said lower end forward and allows said indicating-wheels I I to be returned to their normal positions by coiled springs 71 1' secured to said wheels, respectively, and to the shaft on which they turn, the long teeth of the ratchet striking the pawls i and preventing said wheels from passing the 0 points in their return motions. As soon as the ear j of the spring j passes above the stud 1' the pawl-lever is free to be swung backward to position and against a stop 2 by a leaf-spring r secured to the frame of the machine. (See Fig. 9 The post j on the lever J is merely to support the upper end of the springj when said spring is pressed up against the stud 2' said spring being quite light to allow said stud 1' to move it aside when the releasing-plate and said lever J are returned to position. A T-shaped lever J 2 is secured to the releasing-rod j (see Figs. 1, 1, and 4:) and turns with it, and a spring 7' supported from the inside of the back of the upper part a of the case A, is
provided with a catch j, which when said releasing-plate is raised by the depression of a key to its greatest height reaches over the top of said lever J 2 and holds said releasingrod 7' from returning to position until an arm 19*, projecting downward from the rocking plate P, in being restored to position strikes an arm 7' which projects from said releasingrod below said arm p".
The registering is accomplished simultaneously with the indicating, the registering of tens by the transfer-wheel Z engaging an intermediate gear 1", which engages the registering-gear r, the latter carrying a pawl r which is kept by the spring 7' in engagement with a ten-toothed ratchet r concentric with said registering-gear r and with the tensregistering wheel R and rigidly secured to the latter, the ten figures of registration to 9 being marked on the face r of said registering-wheel R, which, together with the units-registering wheel R, is concealed by the case, which can be opened only by a key carried by the proprietor or some trusted person. ,(See Figs. 1, 2 to 4, and 18 to M.)
The units-registering wheel R is similar to the tens-registering wheel R in having secured to its hub a concentric ratchet rflwhich, as shown in Fig. 15, has, however, only four teeth (but may have a larger even number of teeth) and has on its face only the figures O and 5, (half as many of each as there are teeth in the ratchet-,) alternating with each other, the units-registering wheel being actuated by a pawl r carried by a plate or disk r concentric with said wheel R, and ratchet W, said awl r bein held in en a ement with said ratchet r by a spring 0" also secured to said plate, and said plate 1' being rotated at each movement of the units-indicating wheel an angular distance equal to the angular distance measured by a single tooth of the ratchet r thatis, asthese parts are represented in the drawings, ninety degreesa stud on the pawl-plate 1' being connected by a link 0" to one of the arms of the units-indicating wheel I, the pawl 7' drawing back over the teeth when said unitsindicating wheel returns to 0 from and at each forward movement of said units-indicating wheel from 0 to 5, turning the ratchet r and unitsregistering wheel one tooth. WVhen the unitsregistering wheel moves the angular distance measured by two teeth of the ratchet r 10 must be registered, and this is accomplished by rotating the tens-registering wheel B onetenth of its circumference at every alternate forward movement of the units-registering wheel R. A cam-wheel r Figs. 2, 3, 17, 24C, and 25,is secured to the left end of the unitsregistering wheel or cast in one piece with it and concentric therewith, said cam-wheel having two cam-surfaces r 7", each extending half-way around said cam-wheel and dropping suddenly to the other cam-surface thereof. A cam-lever r is rigidly secured at its lower end to a rod 4", extending from the left side of the units-registering wheel to the left side of the tens-registering wheel and supported and turning in a bracket 0', Fig. 1, secured to the inside of the back of the case A, and said cam-lever r is provided with a projection 0, which bears against the face of the cam-wheel r being held thereto by a spring r, so that at each half-revolution of said cam-wheel T, or, in other words, at every other time the units-registering wheel makes a forward movement, said projection r runs off the end of one of the cam-surfaces of said cam-wheel and allows said cam-lever r and a pawl-lever r also secured to the rod r and a pawl 7- pivoted to the upper end of said pawl-lever r and engaging a tentoothed ratchet r secured to the tens-registering wheel concentrically therewith, to move forward a sufficient distance to rotate said tens-registering wheel one-tenth of a revolution; but obviously this is not all that is required, because, to illustrate, if the unitsregistering wheel already registered 5 and it were desired to register 85 the sum-total of the two registrations should be 90that is, after the second registration the units-registering wheel should show a 0 and the tens-registering wheel should show a 9; but without other mechanism than that above described the complete depression of the eighty-five-cent key would cause the tens-registering wheel to register 8, and, moving the unitsregisterin g wheel the value of one tooth, would cause said units-registering wheel to register 0, so that the sums of the two registrations would appear to be SO instead of 90, owing to the fact that the action of the units-registering wheel on the tens-registering wheel would be simultaneous with the independent action. of said tens registering wheel due to the action of the registeringpawl r and gear 0". The S is therefore registered simultaneously with the movement of the units-registering wheel from 5 to O, and the action of the pawl r and the pawl-lever r is delayed until these registrations have been made, said cam-lever 9 being provided with a spring-arm r which in the forward movement of said cam-lever and pawl-lever strikes against an annular flange r of the registering-gearr, and thereby prevents said pawl 1 from operating the tensregistering wheel R until said tens-registering gear 0" isrestored to position by the dropping of the registering-lever L, said flange r having a slot r which when said registering-gear is so restored to position allows said spring-arm r to pass within the flange and the pawl-lever r to be drawn forward by a spring 7' above named, and by its pawl r to turn the tens-registering wheel one-tenth of a revolution. The sides of the slot r are rounded to allow the spring-arm to enter the slot more readily. The inner edge of the flange r is beveled, as well as the adjacent surface of the free end of the spring-arm W, as shown at the left of Fig. 24:, where the registering-wheel R represents a registeringwheel adapted to register hundreds or dollars, but which is a more duplicate of the wheel R, r representing the flange on the dollar or hundreds registering gear 1' and r representing the corresponding spring-arm, and said last-named flange and spring being represented partly in section to show their beveled surfaces above referred to. In the way indicated the registering devices maybe duplicated indefinitely and the excess of ten be carried from one registering-wheel to the registering-wheel of the next place above.
To compel a complete depression of the keys K, and therefore a full indication and registration of the proper amount, each key is provided with an upward projection 79, having on its rear edge a rack 76*, the teeth of which point downward and engage a swinging pawl k or wing, Figsl, 1, 2, and 3, which extends back of all the keys of the machine and is pivoted at about its lower edge on opposite sides at k and has downhanging arms which each rest upon a leaf-spring k supported at its rear end on the base or table a and bent transversely upward into a V-shaped rib 70*, so that when the lower edges of said arms are back of the rib k the upper edge of the pawl k is thrown forward to en gagetherackslc and when the lower ends of said arms are in front of said rib 70 said pawl is held out of engagement with said racks. The pawl is thrown out of engagement with the racks by the backwardly-projecting ends of the downhanging armsp of the rocking plate P striking the pawl 70 when the key is fully depressed and thrown into position for engagement again by said projecting ends striking the lower arms of said pawl R The pawl 70 is also provided with a notch 7c which when the keys and rocking plate are in their normal position reaches over the rear edge of said rocking plate and prevents the rising of the same, the upper ends of the projections it being cut away at 70 to allow the pawl to fall forward far enough for this purpose. Vhen any key is first depressed, therefore, it throws out a bolt into the slot Z of the lever L, as above described, and does not throw back the pawl k until the concentrically-curved part 70 has risen above the top of the pawl, by which time the bolt has been projected to its greatest extent. The rocking of the plate P also releases the drawer and allows the spring (1' to throw the drawer D open. A bell-crank lever 61 is pivoted to a bracket (1 secured to the under side of the top of the lower part a of the case A, and its lower nearly-horizontal arm d is provided with a hook (1 adapted to reach over a catch d, secured to the top of the drawer or to a partition therein, said catch and hook being beveled, as shown, to allow the catch to be shoved under said hook and to be retained by the hook dropping down in front of said catch. The nearly-vertical arm 61 of said lever reaches up through the top of the part a of the case and terminates in a hook d and beveled end d, said hook being adapted to be engaged by the hook 1), secured to the rocking plate 'P and reaching down (see Fig. 1) below the top of the hook d when, the drawer being open, the horizontal. arm (1* of the lever 61 is thrown downward and the upper arm of said lever is thrown forward. Then the drawer is closed, the hooks are disengaged, and the lower end of the hook p when the rocking plate rises strikes the curved part d of the lever (Z above the hook d and raises the horizontal arm of said lever and releases the drawer. hen the rocking plate falls, the drawer being open, the hook engages the lever and prevents the rocking plate from rising, and therefore pre vents the keys from being operated. The hook 19 is adj nstable laterallyin a slot 19 in the rocking plate P to allow said hook p to be moved out of range of the hook (i of thelever (Z and to allow the keys and rocking plate to be operated when the drawer is open, said hook 19 being held by a shoulder 19 on said hook p and a thumb-nut p turning on the upper end of said hook above said rockingplate, so that loosening said thumb-nut allows the hook p to be, adjusted as above stated.
WVhen the rocking plate P is raised to highest position, an alarm is sounded simultaneously with the opening of the drawer D. A bracket b is secured to therod l and supports a gong or small bell B, and pivoted below the bell B, at N, is a lever b, in such a position that the free front end of said lever 11' will be raised by the rising of the rocking plate, but will slip off from said rocking plate about the time when said rocking plate reaches its highest position and will be carried down again by a spring I), hereinafter described, (see Fig. 2,) until the rear arm strikes against a stop If, projecting laterally from said bracket 1). A bell-hammer lever 6 having an elastic wire arm b and striker b, is pivoted on the same pivot b with the lever b and has a laterally-projecting stop b, which is held by a spring Z2 (which, as shown in Fig. 2, surrounds and is secured to said pawl and at its free end bears against the under side of said lever b against the under side of the rear arm of the lover 1). Hence when the front end of the lever b is raised by the rocking plate the bell-hammer lever b is moved with it, carrying the striker b away from the bell B, and when said front end of said lover I) slips off from said rocking plate both levers are restored to their normal position by said spring I), and, being suddenly checked by the lever Z) striking the stop if, the momentum of the striker Z)" carries it against the bell, the elastic arm b yielding for that purpose and immediately after drawing the striker away from the bell. WVhen the rocking plate falls, the front arm of thelever 1) yields to allow said plate to pass said lever, and is then restored to position by the spring which is weaker than the spring Z2 and at one end is secured to said pivot b and surrounds the same and with its other end reaches under the front arm of said lever 19.
