Original No. 354,433, dated December 14, 1386. Application for reissue filed February 24,1891. $erial No. 382,613.
.To all whom it may concern:
Be it known that I, THOMAS MUNNELL, late of Monnt Sterling, in the county of Mont-- gomery and State of Kentucky, but now residing atBaltimore, Maryland, have invented certain Improvements in Gash-Registers, of
which the following is a specification.
In the desc'iption of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which Figure 1 is an exterior front view of the improved cash-register, and Fig. 2 a back view with a hinged dhor at {he rear open.
directly to strike Fi 3 is a vertical central section as seen fromthe side of the machine, and Fig. 4. a
horizontal section taken on the dotted line 4 4. Fig. 5 is a horizontal section taken on the dotted line 5 5, Fig. 3; Fig. i3 is a rear view of certain parts of the actuating mechanism of the cash-register, and Fig. 7 a perspectivcview of: the mechanism which serves the cashdrawer alarm-bell. Fig. 8 is a perspective view of a part of the operatingdial, as seen from its inner face;-
and Fig. 9, a similar icw of the out-er face of the same. portion of the dial and some of its immediate connections. Fig. 11 is a perspective front View of a portion'of the said actuating dial and certain parts of the mechanism which serve to operate the cash-drawer. Fig. 12 is a perspective view of the lower end of a lever which constitutes a part of the drawer-operating devices and a portion of the lid of the.
, This invention relates to cash registers; and itconsists in the use of an operating-dial,
a private registering-dial, and exposed customers dial, indicating-hands for the register- I ing and'custo'mers dials, and suitable nicely.
' anism interposed between the operating-dial and the other two dials, whereby the hand on I the customers dial will indicate each rotary movement of the operating-dial in either di rection, and the hands of the private dial will :Eiin the door 0, but is expo d t View when The door 0 has a look, so
indicate the sum total of the amounts reprebe termed the It also consists in providing the perating- Fig. 10 is an edge view of a rangedlevers,representing a series or numbers arranged in arithmetical progression, adapted to be projected from the face of said dial, and when the dial is rotated to come in contact with a stop on a fixed part of the registcr. The rotary movement of the dial will I cause to be registered and indicated. on the priva-te dial and customcrs dial, respectively, a number corresponding with the'number oi whateverlever may be projected.
It further consists in mechanism for sounding analarm and opening the cash-drawer,
which mechanism is operated by each movement of the operating-dial :in a registering direction.
Referring to the drawings, A is the case of. the cash-register, and B a hollow base for the case A, in which a stationary cash-drawer hereinafter described is situated.
D is a circular flanged plate, secured within an opening in the front wall of the caseA. Phis plate is shown in section in Figs. 3 and i.
E is a shaft, with its front end j ournaled in the plate I). The rear end of this shaft is square and adapted to fit into a sleeve b, which turns loosely in, a dial-plate F, secured to a door 0, which forms the back wall of the case A. This door has-a circular. opening (I, furnished with a glass plate 6, through which the dial F, which is termed the customer's dial, is visible.- The sleeve 1) is provided with a hand f, which, when the'door c is closed, turns with the shaft E. The front end g of the shaft E is also square and passes through asin ilarly-shaped hole in accni-ral boss 71- on the operatingdial G. It will thus be seen that the shaft E, sleeve h, and the hand f may be'turned through. the medium of the operating-dial-G.
: H II are posts projecting rcarwardly from the plate. D, which supports a bridge-piece I,
to which astationary or fixeddial-plate J, ter1ned.a.--pri vate dial, (see particularly Fig.
4 is secured. This private dial is ordinarily hidden from' view by the fixed customers dial that-doorv is open.
t-oi prevent the private dial being tampered with.;- l i I K is a loose sleeve on the shaft E, carrying a hand k. -L is a second sleeve placed loosely r dial with a series of c'ircum-ferentially -ar- (onthe sleeve K, provided with a hand I; and
M is a third sleeve, fitted to turn loosely onthe sleeve L, having a hand in, (See Fig. 3.) The'mechanism through which .motion is communicated to the hands 7c,,Z,and'mfrom the movable or operating dial G is arranged as follows An arm N, rigidly secured to the shaft E, carries a pawl n, which rests on the. edge of a spur-whecd O, fastened to the sleeve K. As the shaft E is rotated the arm N will also rotate, andwhen moving in one direction the pawl n will lock with one ofthe teeth on the spur-wheel O and cause the wheel toturn with the'shaft E; but when the shaft E is turned in the opposite direction the pawl n will slip over the teeth on the wheel 0, and
the latter will therefore not be moved. The
spur-wheel O has a pinion-P, integral with it, I
which is in gear with a spur-wheel Q, of the same diameter as the one. 0, loosely mounted on a stud o,projecting'from the bridge-piece I. This second spur Q, carries a pinion R, corresponding in size with the one 1?, which pinion R is in gearwith a spur-Wheel S, attached to the sleeve L, and this spur-wheel S carries a pinion T, which is the same size as the ones P and R and is in gear with. a fourth spur-Wheel U, placed loosely on the stud 0 and provided with a pinion V, corresponding in size vwith those before described. The pinion'V is in gear with the spur-wheel WV, integral with the sleeve M. All the'spur-wheels have one huni dred teeth each. and the pinions ten teeth.
Consequently when the movable dialG and the hands f and is make a complete revolu-. tion the hand I makes the on-hundretli part of a revolution and the hand in the one-hundreth part of that. I From the foregoing it will be seen that whil the operating-dial G,'sl1aft E, and the hand f .may be turnediu either direction the.hands k,Z, and m move in one direction only.-
' The movable dial G has twenty holes near its periphery, which are numbered from O to 95, advancing by five, and through eachhole projectsa loveroA', having an exterior knob a. The knobs a serve as finger-holds to rotate the dial G. These levers, which are bent at a right angle, are pivoted to lugs b on the inner face of the operating-dial, and the rear arm of each lever is held yieldingly-to the said inner face by means of a spring-wire 0'. (See particularly Fig.8.) p
The rear side of the operating-dial G has a lug g which, as the said dial is turned by anyone of the knobs a inthe non-register- 7 ing dircction'indicatedby thearrow in dotted lines in Fig. 1, comes incontact with a stop 9 on the plate D, andstops the said dial with the zero 0) mark at the top of the said plate, and the hand f at O or the zeropoint of the customers dial F, which has numerals co'rre spending with those on the operating-dial G. Thcbackward movement of the operatingdial G, as described, has no effect on, the "other hands k, l, and m, in view of the pawl "n clicking. over the teeth of the spur-wheel O. This backward movement-of the operatprivate dial ninety-nine.
.ing dial G is always the preliminary step to registering a sale, and when itis completed 7 theoperation' of registering a sale merely consists in turning the said operating-dialin a forward direction, as indicated by the arrow in full lines, by means of the knob indicating the amount to be registered, until the the arrow in full lines, Fig. 1) by means of either of. the knobsa the pressure on the knob will cause the attached lever to swing in its bearin s b and 'ro-ect its inner arm outwardly against the pressure of the spring 0 as shown in Fig. 10. The inner arm of each .leveiywhen so projected, is adapted to engage thestop g and thereby arrest the movement of the dialin the registering di- 'rection. From this it' will be seen that the stop g serves to arrest the rotation of the dial in either direction and serves as the starting and stoppin glpoint in each successive registration. Thepressure exerted on either of the knobs in turning; the dial iii-a non-registering direction will {not move} its attached:
lever from the normal position.
As theseries of leversrepresent a series of numbers advancing in arithmetical progression by fives, it i's'clear that only numbers divisible by five canhe' registered by a single movement of the dial br tt e-registering direction. \Vhen, ther fore, it becomesneeessary to register a number not divisible by five, the additional units anust be registered. I
by the lever opposite the zero-pointon the dial, this lever being so arranged as to move the dial a sufficient distance in a registering direction to cause the spur-gear O to fillrnthe space of one tooth before it (the lever) engages the stop '9 Oonseguently each of such 'movements of the dial by thezero-lever would register one Limit. To illustrate: Supposing the sale to be ninety-nine cents, thefJ5-knob must be employed. At the first operation ninety-five cents are registered, and then the zeroknob must be moved, as was theot-her, four times, which adds four. more units to the already-indicated ninetyfive, thus making the full number recorded by the hand k of the It will be understood that'with the train of multiplying-gearing described the hands 7;, Z, and m of the private dial indicate, respectively, cents, dollars, and hundreds of dollars, and on it the sales for any period of time are recorded by them, provided allthe said hands are placed at the zero-point at the beginning.
.In order that the train of gearing described may be held so as to have no hackwardmovemerit, a rubber or brake O is attached to a post (1, so as to engage with the periphery of a disk D, which has a rotary movement in coinmouwith the spur-wheel 0. (See Fig.- 3.} E" "1s a stationary cash -,dmwe1-,' having a sliding lid c with springs f', which have IIS the effect of forcing it out when it is not ,Inent with the lug 'i'.' The upper end of the lever g passes through a staple k projecting from the plate D, (seeFig. 11,) which limits its vibratory movement, and immediately below the staple k is an inclined projection m.
Vhen the operating-dial G is turned in ya registering direction, the projected arm of the lever used to im-pel' it will, just before it reaches the stop 9 come in contactwith the upperend of the lever g. and cause said lever to swing on its pivot h and disengage its hooked end from the lug "i' on the lid of the cash-drawer. As soonas this disengagement takes place the springs)" will. project the lid 6' forward, asindicated in dotted lines, Fig.
is pushed forward 3, thereby permitting access to the cash drawer E. As the upper end of the lever g it will ride up the inclined projection m, which will force it sidewise until it becomes disengaged from the projected arm of the lever used to impel the dial. The helical spring j will then return the lever 'g' to its normal position, ready to again lock he lid of the cash-drawer. In order that an alarm may be sounded at the beginning ofeach registering movement of the operating-dial G, a bcllF' is placed withinthe casing,together with suitable means to strike it. This striking mechanism is shown in Figs. at, 6, and '7, and it consists of a bar G, having its ends journaled in the plate D and bridge-piece I. The bar G has a longitudinal slotrm into which-the end of the arm N is adapted to enter when the op eratingdial G is turned to its limit in a non-registering direction, or to what may be termed the zero-point. The bar G carries a bell-hammer n,.adapted to strike the bell F when the bar G is forced by the spring" 0' into the position shown in dotted lines in Fig, 7. The spring 0 is bent to form aloop O and is attached at one end to one of the posts H, while its other end enters a tube Q rigidly secured to the bar r. This device operates as follows: \Vhen the operating-dial is returned to the zero-point, the arm N will enter the longitudinal slot m and carry the, bar G and the bell-hammer n" to the posi: tion shown in full lines, Fig. 7. Then, how-,1
' ever, the operating-dial begins, its movement the rotation of said bar,
in a registering direction, the arm N will par tially rotate the bar G in its bearings and the spring 0' will then operate to continue causing the bcll-ham,- mer to descend quickly and strike the belt 1 as indicate-din dotted lines, 7'. A short arm 0 proj ectingrearwa-rdly trom the bar-G, is adapted to come in contactvvith the post llfo limit therota tiou of the said hammer it in order that the resonance of the bell may not be interfered with.
The cashrregister is placed so that the rear will be in full view of the customer, in order that he may see by the customers dial that registered.
