Be itglmown that I, C ARLES SULFER, a citizen of'the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certainnew and useful Improvements in Total-Adding Cash-Registers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference'being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

. 'This invention relates to improvements in cash registers and more particularly to a cash'register of that 'class adapted to be operated without the use of lever keys. Ofthe many cash registers heretofore devised most have been provided with levers, whereby the operator, by pressing upon the appropriate lever actuates mechanism for recording the amount of the transaction. With all such registers continued use serves to put the register levers or keys out of alinement and'it sometimes happens that a dishonest employee may be able to make the machine record incorrectly for that reason, and owing to the use of levers and the multiplicity of parts, it is not uncommon for such registers, when out of order, to record incorrectly at times without the knowledge of the operator, making it impossible to determine with certainty the-result of the days business.

With thisin view, the object of this invention is to provide a cash register operated wholly by means of rotary elements and by dials each appropriated to a single denomination of the money to be counted.

It isalso an object of the invention to provide in a device of the class described, rotary mechanism for recording the transacr tion' or purchase, and simultaneously exhibitiing in a suitable view aperture, a visible sig- I na they occur, and in which the-{registering} \rnechanisrncah be setback tolO, very qu ckly...

It is an important object "of the invention also toaflo' fdin connection-with mechanism of theiclass described, a total addingiregister,

which,-howso'ever the dials are operated, cannot falsify the record, each dial operating 111- H enlarged dependently to insure an accurate count and I the dials for lower denominations carrying the count automatically to those of a higher denomination. i" i i The invention embraces many novel fea- 6.0

As shown in the drawings: The mechanism is mounted upon a base A and within a removable casing A beneath which is the usual or any suitable money drawer A and is supported within a frame consisting of end plates a and a, which are rigidly secured to the base plate A. J ournaled centrally on said end frame members and supported upon suitable bearings, is a shaft B,

which protrudes through the front frame plate a, and is provided thereon with a dial B, having marked thereon at equal distances apart and approximately in a semi-circle near its periphery, the numerals and signs $1, $2, $3, $4, and $5, reading from the bottom upward. f course any desired number ofv dollars up to and including nine dollars may be indicated thereon.

As shown a standard B is supported on the base and affords a support for the end of said shaft B. The shaft Bis journaled near its middle portion on an upright or standard I), supported on the base-plate A, as shown in Fig. 4. Rotatively mounted on said shaft concentric therewith and extending inwardly thereon, from the front end, is a tubular shaft C, having a dial C thereon, similar to the .dial B, and rotative around the same and marked consecutively on approximately half its periphery to indicate dimes'from 10 cents to 90 cents, in elusive, and mounted to rotate on said shaft C, is an outer tubular shaft D, having a dial D, rigidly secured thereon, and marked from 1 to 9 inclusive on a semi-circle to indicate pennies. Said dial, is shaped to fit around the dialC, and all the dials are arranged with their faces in the same vertinea'th the numeral 1 on the dial D" and at the same distance therefrom, as the nu"- merals from'each other is marked No sale. As shown said numerals on each dial are marked upon a circular button (1 secured in suitable sockets in the dials and which are made of cast, or pressed metal, or any material suitable for the purpose, and a spring 01', shown in Fig. 36, normally holds the other face of said button flush with the face of the dial but permits the same to be pushed lnwardly to enable the finger to engage in the socket to rotate the dial.

Rigidly secured on the shafts B, C and D are cams or wheels, such as shown in Fig. 12, and indicated as a whole by B C, and D, for the respective shafts, these, as shown, are each provided with a single angular tooth b"- cd. The number of said cams on each shaft .is the same as the number of stations on its dial, in other distances apart in approximately a semicircumeference to correspond with the arrangement of. the numerals on the dial. Said cams are spaced a slight distance apart on the shaft, by means of a relatively thin plate a of metal engaged between adjacent cams, as shown in Fig. 4, and which are rigidly secured on their shafts by keys or by a projection suitably positioned with central bore in one of which w is shown in Fig. 12. They are'also secured in place by means of nuts d"'ic -b, threaded on the respective shafts and between which and the cams, on each shaft is rigidly secured a gear-wheel b-c-d*.

Rigidly secured to the front and rear frame plates ar- -a' by means of its downwardly bent ends H", as shown in Figs. 5, 6 and 16," is a rigid horizontal bar E which is positioned at the left of and above the dial shafts, and a central depending bracket c is secured at about the middle thereof and, extending through said bracket and the end e of said bar, is a non;rotative shaft Pivoted on said shaft e between the bracket c and the end bracket e are inwardly directed arms c -e, which extend to near and above said gears on said dial shafts, and are connected intermediate their ends by a rigid horizontal bar E on which just at the rear of the gears d and b are secured inwardiy directed rigid arms E. These are in length equal to the projection of the arm e beyond the bar E and each is provided with a downwardly directed spring controlled pawl e, at its extremity positioned to be engaged by a cam e secured on the rear side of each gear wheel, on each dial shaft, and which acts to lift all said arms simultaneously. Also secured on said shaft e and projecting forwardly over the bar E are relatively broad leaf mit the arms to swing upwardly against the tension of the spring.

Hinged on the base plate A opposite each set of cam wheels is a standard shown'more, plainly in Figs. 8 to 11 inclusive. This, as shown, comprises a projection or boss f, rigidly secured to the base plate, and on the top of which is hinged a tubular body F, as

shown in Fig. 11, in which is slidably engaged a cylindric and threaded stem f, held from turning therein by means of a'pin f, secured in said stem and extending into a longitudinal slot,

blade or plate f having its upper edge i of the leaf spring 6.

is provided near said end on its under side.

directed horizontally and longitudinally of the machine and rounded to afford a support, and of a length to extend across the face or .edge' of all the cam wheels in the set oppositewhich it is secured. Supported at their inner ends on the upper rounded edge 7" of said hinged supports, are transversely slidable pawl bars G, which equal in number the cams in each set and are positioned respectively directly above each of the cam wheels. Each is provided at itsinner' extremity with anupwardly directed projection or tooth 9, adapted to engage beneath and behind the down turned lip or detent e As shown also each with a notch having downwardly and outwardly inclined sides toward the adjacent end of the bar, and the other side therof affords a somewhat rounded shoulder 9 Directly above each cam wheel a downwardly extending tooth g is provided on each pawl bar, adapted to be engaged only by the tooth on the corresponding cam wheeh As shown also said pawl bars betwen the tooth on each, and the shoulder g are cut away to afiord an inclined face. for engagement by the teeth on the cams as the same are rotated forwardly thereby lifting the ends of the pawl bars. At its opposite end, said pawl bar is pivotally engagedand supported upon a lever G, the upper end of which projects above the top plate a As shown also a comb 9 is secured beneath the top plate, and the teeth thereof extends downwardly between the said pawl bars, holding the same positioned each directly above its actuating cam.

Arranged obliquely on the upper side of the top plate as shown in Fig. 2, is a set of bell cranks H, ten in number corresponding with the 1 number of cams on the penny shaft, D, and rods 72/, connects the forwardly directed arms h, with the upper end of the lever G, before described. The opposite arm 71;, which is directed transversely the machine, is pivota'lly engagedby a rod k which leads rearwardly,-and 1s adjust ablyconnected with a downwardly directed arm h, of a lever h which is pivotally supported at the rear "end of the frame, 1 as in said tubular body. Said stem is ad usted as to height by meansof a nut f and jam nut f,

- out contact.

ated pawl bar. passes beneath the spring shown in Fig. 4 Saidlevers extend forwardlythrough a vertical comb h, and are each'p-rovided at its forward end, with an upwardly directed arm 71.", on the upper end of which is a tablet 72?, which may be as shown of circular or any desired or suitable form and on the front and rear faces of which there is marked or indicated the numeral, sign or other representation or representations contained upon the button of the -dial from which said pawl arm is actuated. 'There are, of course, as many of said levers as there are stations on all the three dials including the No sale station. In-

asmuch as ten of said levers are appropriated to penny dial, nine to the dime dial and five to the dollar dial, there are also necessarily ten of said bell cranks in the series'H,

for pennies, nine in the series H for dimes and five in the series H for dollars, each of which when actuated by its pawl bar acts to elevate the proper tablet to afiord a visible signal in the viewaperture A, at the top of 'thecase. Inasmuch. as the tooth on the cam, correspondin meral on the dial 1t is'desired to record, is directly in front of the tooth g" onthe pawl bar said teeth on the cams engage and successively lift the pawl bars, against the tension of their springs g", shown in Figs. 6 and 16, until he completion of the forward movement or count ofthe dial. When the dial is released at the end'of the forward movement, the tooth d 'c orb on the cam, corresponding with the count to be represented and which has just'passed and is )ust in position with the nuj in advance of the tooth g on the corresponding pawl bar, immediately engages said tooth g as the dial returns to its normal position, and said pawl bar is moved lengthwise pushing the hinged support F, therewith and thereby elevating the adjacent ends of the remaining pawl bars, (owing to the inclined surface of the notch in said pawl bars in which the top of the support rests) to a height to let the remaining teeth on said cams pass beneath, with- The end of the positively actuplate '6, to be retained, elevating its tablet into view, until a dial is again actuated when the cam e engages the pawl 6 end of one of the arms 6 or E lifting the on the same and releasing the pawl bar'andpefi mitting the visible signal' to fall Of course any suitable mechanism may be provided to return the dials and'cams to position for the next count. For th s purpose,

to said standards i, are strong coiled springs i, which are wound up by rotation of the withthe gears d*.0*b* reand securedto the axle or shaft for each said gear, and

respective dial shafts when actuated by their dials, and act to quickly return the dial actuated to normal when released. v As shown in Fig. 16 means are provided to insure the dial always stopping at normal. For this purpose a stop 5 which may be integral with the cam projection e is rigidly secured on the dial shaft gear b*-c and engages the top of the appropriate standard mwhen the dial is, at normal. In the same manner the opposite end of said stop or any suitable stops may be provided on said gears to engage the standard 2' or any suitable rigid part of the machine, to limit the 5 downward movement of'the dial when actuated to make its'maximum count. As

shown, both said stops and the cam projec tion a", are formed from single plates of the proper 'size and shape rigidly secured on the rear side of each gear. The return .movement of the dial, and cams under the action of said springs, is also regulated to prevent pounding or injury to the machine. For this purpose a governor is provided comprising a shaft J, journaled on suitable standards J'J'* secured on the base plate A and gears 7' are rotatively securedthereon in-mesh with the positively driven gears I, for each dial. As shown in Figs. 6 and 28, a disk 7', is rigidly secured on each gear j and bearing against the face of said' disk is a ratchet 7' rigidly secured on said shaft J, and which is engaged by a spring controlled pawl 7' on said disk' 'j', thereby rotating the governor shaft J, as the dial returns to position. )n the rear end of said governor shaft J, is secured a ear 7' which meshes with a pinion j, secure "on the. same shaft with a gear 7', which in turn meshes 40 with a pinion 7',- which drives a centrifugal governor J of any suitable kind, and which is provided at one end ,withia friction brake wheel 7' adaptedto be en aged by ashoe 7', as shown in Fig. 5.- aid governor is of'the dials when .any one or more of the dials are actuated and acts to retard the re- Y turn movement'of the dial toprevent shock due to .violent impact of the stops 2?, on the 0 standards iflthough' of course if neces'sa said governor may be drlven when the dials are rotating in either or both directions.

Means are provided for making an audible signal and to unlock the money drawer simultaneously with the actuation of the dial. For thisi'gpurpose a pivoted spring pressed finger is, secured on each of the gears. bc d and project beyond the periphery thereof sufliciently to engage arms is, secured on a'shaft k, which extends lon= "gitudinally of the machine beneath the top plate a, and through the rear frameplate a as shown in Fig. 7. At the rear side of the end plate a, a bar-la isrigidlysecuredat its middle on the shaftk', and on one end of the bell, and as the bar returns to'normal en.-

obviously driven .on the return movement longer period is provided. F or this -pursame is provided a strong pulling spring is,

which acts .to hpld said end firmly down upon a stop la Apad which may be, of

rubber or 'other suitable material is secured on the end gf said bar to absorb the'shock of the returirbfsaid bar to normal position after actuation. A bell K. is secured on said frame plate a, and a hammer 7a., is secured on a spring rod lo, iii-position to strike said bell when actuated. As shown also a depe'ndin'g hooked arm is is pivotally engaged .on said end of said bar F, in position to engagethe protruding end of the spring rod k, beyond: the hammer ;and lift the same and av spring is, is engaged on said arm and acts to hold the same normally inward in position to engage said hammer rod. "A stop 1 k is secured on said frame platetolimit the inward swing of said arm 71", under the action of its spring, and the inner side of the arm is so shaped that when the" bar K returns to normal the hooked end of the arm, is", swings beneath and engages the hammer so that rotation of said shaft It. acts first to release the hammer, sound the signal on the ga ed the hammer on the arm 70'.
