dated August 2, 1892.

Application filed January 4, 1892. Serial No, 417,045. (No model.)

To all whom it may concern.-

Be it known that I, XVILLIAM KNICHOLS, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Improvement in Cash -Registers, of

which the following is a specification.

This invention relates to a cash-register having series of indicators, which are thrown in sight to indicate the amount of the purchase or other registration, and which contains a registering mechanism for registering the aggregate of purchases or of other registrations for any required period.

The objects of thisinvention are to provide a cash-register in which the mechanism will be simple for an apparatus of this character; which will register accurately the aggregate of a long series of transactions extending over weeks, months, or years, thereby affording a check against false entries at the close of each day or other short period; which is locked against false registration; which is permanently sealed, affording no access to the interior of the case, whereby tampering with the registering mechanism is prevented, and which is substantially perpetual or continuous in its registration, no setting back of its registering-wheels being required.

Figure l of the accompanying drawings represents a front elevation of this cash-register, the indicating-plates being thrown up to show a sale of $179.40, the total registration showing through the reading-slot being in this instance$987.et5. Fig. 2isa plan thereof, the upper casing, the key-locking mechanism, and the drawer-releasing mechanism being omitted. Fig. 3 represents a transverse section of this improved cash-register on line 3 3 of Fig. 2, a portion of the left-hand end of the dome and a portion of the bell being broken out to show the mechanism beyond. Fig. t represents a horizontal section showing the drawer compartment, the drawer therein, the mechanism for releasing and locking the drawer, and the spring for throwing it out when released, the top plate of said compartment being broken out, except at the lower right-end corner of the figure. Fig. 5 represents on an enlarged scale a diametrical section of the registering-wheels and their supporting-arbor. Fig. 6 represents an enlarged plan of one of the registering-wheels,the sleeve to which it is attached, the ratchet-wheel on said sleeve which is actuated by the keys and the ratchetavheelon said sleeve which is actuated by the adjacent registering-wheel to the right, the pawl-carrying arm actuated by the keys, its sleeve which rides upon the sleeve of the numeral-wheel between its two actuating-wheels, the arbor on which the sleeve of the numeral-wheel rides, and the flange on said numeral-wheel carrying the pawls for actuatingthe next adjacent n umeralwheel to theleft. Fig. 7 represents a perspective view, on an enlarged scale, of a segment of the periphery of one of the numeral-wheels in a modified form, and also a segment of the periphery of the actuating-wheel for the adjacent numeralwheel to the left, the dog for communicating motion from one of said wheels to the other, and the lug for depressing said dog, said lug being broken off from the case. Fig. 8 represents on an enlarged scale the dog for communicating motion from one of the numeralwheels to the other and a fragment of its supporting-spring. Fig. 9 represents on an enlarged scale a perspective view of a portion of the mechanism for lifting the bars of the indicator-plates and for holding them in position and the mechanism for releasing said indicator-bars. Fig. 10 represents a perspective view, 011 an enlarged scale, of a portion of the mechanism for actuating the registering-wheels and the device for retracting or depressing to its normal position the pawlcarrying lever of the cents-wheel, which lever is lifted by two separate arms connected with different sets of keys and engaging a pin on opposite sides of the retracting-bar. Fig. 11 represents on an enlarged scale a planet the mechanism for locking the different rows of keys. Fig. 12 represents 011 an enlarged scale a front view of said mechanism for locking the different rows of keys, a portion of the front of the casing being broken out to bring this mechanism into view. Fig. 13 represents on an enlarged scale a vertical section through anumber of keys of the same row and through the mechanism for locking different keys on the same row, one of said keys being represented as partially depressed and the others as locked. Fig. 1% represents a horizontal section of the parts represented in Fig. 13 on ICO line 14 14 of said figure. Fig. 15 representsa transverse vertical section on line 15 15 of Fig. 13 through one of the keys and the locking mechanism therefor. Fig. 16 represents an inner face View of one of the screens, a row of indicating-plates when in their normal positions, and the notched flange on said plate which serves as a guide for the rods of the indicator-plates.

Similar numerals of reference indicate corresponding parts in all the figures.

The case 20 of this improved cash-register comprises abase-plate21,a paneled frontplate 22, having a drawer-slot, a stepped plate 23 above said paneled plate for the different rows of keys, a curved central dome 24 above said stepped plate, covering the registering mechanism and being provided with a readingslot 25, closed by a transparent plate, through which the aggregate of the registrations may be read, receding curved plates 26 and 27 above said stepped plate on opposite sides of the central dome, a back plate 28, and an elevated compartment 29, surmonnting the rear portion of the case and extending longitudinally thereof. This elevated compartment is provided with windows 30 and 31 on both its front and rear faces for exhibiting the indicating-plates of the amounts registered in both directions toward the front and rear. These windows are of sufiicient vertical width to exhibit two or more indicating-plates on different planes corresponding to the different denominations of the keys of the keyboard. The top of this compartment is closed by a plate 32. A horizontal partition 33, disposed above the base-plate 21, together with said base-plate and with the end and back walls,forms a drawer-compartment in the lower part of the case.

The construction of the casing may vary more or less from that above described, and it is preferably firmly united and unprovided with any lid, door, or other opening which would afford access to the interior thereof, the object being to permanently seal the case, so as to protect the registering mechanism against tampering and to prevent false entries therefrom, as the mechanism does not require to be set back to zero and shows the aggregate amounts registering from day to day.

The drawer 40, which slides within the drawer-compartment, is provided with two teeth 41 and 42, disposed at its rear and at opposite sides thereof, which teeth are engaged by the locking mechanism, hereinafter described, for holding the drawer closed. A spring 43, attached to the inner face of the back plate of the easing,bears at its free end against the rear end of said drawer and tends to throw out the drawer when the latter is released from its locking mechanism. The elevated compartment 29 is provided on its front and rear faces, near its opposite ends, with the signs for indicating cents, disposed opposite the lower portion of the windows of said compartment where the indicating-plates representing the cents registered are displayed, and with dollar-signs on the planes in which the dollar-plates are displayed.

The particular species of drawer-locking mechanism which I consider as of myinvention will now be described. This species includes a yoke-shaped lever 50, fulcrumed on pivots 52 and 53, projecting inward from opposite ends of the case above the drawer-compartment. The front bar of this yoke-shaped lever extends longitudinally of the keyboard in position to be actuated by the keys of the front row, as hereinafter described, and it is provided with a number of longitudinal bars, as 54, 55, and 56, adapted to be actuated, respectively, by the keys of the other rows. The inner ends of this yoke-shaped lever are provided with spring- dogs 58 and 59, which engage the teeth ll and 42 on the ends of the drawer 40. The said teeth are beveled inwardly to act as latches for lifting said dogs when the drawer is pushed in. The drawerlocking lever is held in its normal position for locking the drawer and returned to said position when released from the keys by springs 60 and 61.

The mechanism for indicating the individual sums registered may be of any suitable character adapted to be actuated by the keys of this machine; but I have herein illustrated a particular species of indicating mechanism for throwing up, holding, and releasing the indicating-plates which I consider of my invention, as hereinafter pointed out in the claims. scribed. A horizontal rod extends longitudinally through the case from end to end thereof above the drawer-compartment, and a number of levers 71, corresponding with the number of keys in the machine, are fulcrumed on said rod 70 by means of sleeves 72, the ends of which abut along the rod. These levers are of substantially the same construction, excepting that they are of different lengths, terminating at their front ends under the different rows of keys. A number of vertical rods 73, corresponding with the number of cents-keys, are pivoted at their lower ends near the inner ends of those of the levers 71, which extend under and are actuated by the cents-keys. These rods are provided near their upper ends with branches 73'. Indicatingplates 74 are attached to the tops of the rod 73 and to the tops of the branches 73'. These plates 7 4 are provided on their outer faces with numerals corresponding to those on the centskeys which they respectively represent. Vertical rods 75 are connected at their lower ends withthose of thelevers 71, which are actuated through the units-dollar keys, said rods being also provided with branches 75'. These rods and their branches are provided with indicating plates 76, having numerals representing units of dollars and correspondingwith the numeralson the units-dollar keys of the keyboard. Vertical rods 77 are connected at their lower This mechanism will now be deends to those of the levers 71 which are actuated through the keys representing tens of dollars. These rods 77 are provided with indicating-plates 78, containing figures representing tens of dollars, the several plates corresponding, respectively, with the tens-dollar keys of the keyboard. The several series of vertical rods 73, 75, and 77 are connected to the levers 71 at slightly-different distances from the inner ends thereof. A guide-bar 79 extends longitudinally of the machine near the upper ends of the rods 73 and is provided with a number of holes, through which the rods 73 slide and by which they are guided and steadied in their movements. The vertical rods of the cents-plates, units dollar plates, and tens-dollar plates are of three different lengths, so as to project their respective plates into different planes opposite the windows through which said plates are-displayed when the corresponding keys are actuated. When in their normal positions, the cents-plates are below said windows.

The elevated compartment 29 is provided with two screens 80 and 81, which extend longitudinally thereof and hide the dollar-plates from the view of either window when in their normal positions, and this compartment is also provided with two screens 82 and 83, which also extend longitudinally thereof in a plane substantially above the screens 80 and 81 and in vertical planes which extend between said screens 80 and 81. These screens 82 and 83 hide the tens-d ollar plates from view through either window when said plates are in their normal positions. The screens 80 and 81 are provided with notched flanges 84, which serve as guides for steadying the rods of the units-dollar plates, and the screens 82 and 83 are provided with like flanges 84, which serve as guides for the rods of the tens-dollar plates. The cents-plates 74, attached to the rods 73, show through the front window in front of the screen 80 and the cents-plates attached to the branch rods 73 show through the rear window in front of the screen 81. The units-dollar plates 76, attached to the rods 75, show through thefront window in front of the screen 82 and above the screen 80, and the units-dollar plates attached to the branch rod 7 5 show through the rear window in front of the screen 83 and above the screen 81. The double-faced ten-dollar plates 78, attached to the rods 77, show through both the front and rear windows 30 and 31 in a plane above the display-planes of the other plates and above the screens 82 and 83. In view of this arrangement of the indicatingplates and screens the cents-keys can be arranged in complete rows,the dollarkeys in a complete row or rows, and the tens dollar keys in a complete row or rows, all the plates being thrown in sight by the same extent of upward movement, and it is impossible for the plates of one denomination to ob scure the plates of another denomination when two or more plates are elevated to their respective indicating-planes.

Means are provided for lockin g the elevated indicator-plates in their exhibiting positions for one registration until a key is struck for the next registration and for returning said plates to their normal positions when a succeedin g registration is made. The means herein shown for this purpose constitute a feature of this invention and may be employed in cash-registers in which other features differ from those herein shown. Afixed rod 91 extends longitudinally of the case, at the rear thereof, just above the drawer-compartment.

A yoke-shaped rocking frame is disposed on said rod and extends longitudinally within the case, being provided with a pivot-sleeve, as 92, abutting against the right-hand end of the case, and with a pivot-sleeve 92, abutting against a pin 93 in said rod 91, near the lefthand end of the case. The inner ends of the levers 71 rest on the rod 91 when in their nor mal positions, and when lifted they rest upon the top of the yoke-shaped frame 90. A spring 94, attached to the rear plate of the case, bears against the rocking frame 90 and tends to swing it forward. A pin 95 on the right-hand end of the case serves as a stop for said rocking frame in its forward movement and holds the same in its normal position. The longitudinal bar of this yoke-shaped frame has an inner inclined cam-face 96 extending throughout its length, and one of its end bars is provided with a pivoted dog 97 and with a stop-pin 98 above said dog. Alever 99 is pivoted on the rod 70, its sleeve abutting against the lockingpin 70 and the sleeve 72 of the left-hand lever 71. The outer end of this lever 99 extends forward and upward under the drawer-releasing lever 50 or under one of the cross-bars thereof. \Vhen a key is struck, the front end of said lever 99 is depressed and the rear end thereof elevated. In its upward movement the inner end of said lever comes in contact with the tongue of the dog 97 and swings said dog against the stop-pin 98. The lever then rides over the dog, whereby said rocking frame is swung backward a distance sufficient to release those of the levers 71 of the last registration which remained supported on the yoke. After the lever 99 has passed over said dog the yoke-shaped frame is released and returned to normal position by action of the spring 91. Then the lever 71 of the depressed key engages the cam-face 96 of said yokeshaped frame an d swings it backward. When the end of said lever 71 is elevated to a plane above the top of said frame, the spring 9; again swings said frame forward, and it latches under and supports the inner end of said lever, holding theindicator-plates thereofin elevated position until the next registration is made. After the depressed key or keys are released and returned to their normal positions the drawer-releasing lever 50 is also returned to its normal position, thereby releasing said lever 99, which is restored to its normal position byaspring 100. In its descent the inner end of said lever 99 comes in contact with IIO the tongue of the dog 97 and swings said dog out of its path. After the descent of the released lever 99 the weighted tail 101 of the dog swings said dog back to its normal position, where it is ready to be again engaged by the lever 99 when the latter is again lifted.

By this means any one or more of the indicating-plates which have been thrown up to indicate a given registration or the amount of a single purchase will remain displayed until the next registration is made.

The rocking frame is provided with a striking-arm 102, having a bell-hammer 103 at its outer end, which strikes the signal gongbell 104 whenever the rocking-plate swings forward to engage one of the levers 71. The gong-bell 104 may be supported at any convenient position within the case.

The registering mechanism herein shown will now be described. A fixed rod extends longitudinally of the dome 24, being supported in ears 117, depending from the ends 111 and 112 of said dome. This rod is provided near its opposite ends with transverse locking- pins 113 and 114. The registeringwheels are journaled on this rod between said pins. The number of these wheels varies in different machines, according to the denomitions of the keys of the keyboard. In the machine herein illustrated four registering or numeral wheels are employed, to wit: a cents-wheel 120, a units-dollar wheel to the left of the cents-wheel, a tens-dollar wheel to the left of the dollar-wheel,and afinal wheel 150, representing hundreds of dollars disposed at the left of the tens-dollar wheel and solely actuated thereby. A sleeve 121 is disposed on the rod 110, its right-hand end resting against the locking-pin 113 and its left-hand end abutting against the sleeve of the units-dollar wheel 130. This sleeve carries the cents-wheel 120 at its inner end and an actuating-disk 122 to the right of said centswheel, said wheel and disk being fixed to or cast with said sleeve. The peripheral rim of the cents-wheel is connected with the hub thereof either by spokes or a Web. In the machine shown the periphery of the centswheel has six general divisions, each division having aseries of twenty numerals from 00 to 95, arranged in multiples of five. This Wheel is provided on its left face with atlange 123,having six holes, as 148, one for each general division of the wheel. Six spring-dogs 124 are attached to springs 124, disposed on this flange, each dog having a beveled tooth 125 and a cam-face 120. The teeth of these dogs project through their respective holes in said flange and engage the actuating-disk of the units-dollar wheel for turning it one tooth whenever the cents-wheel passes from 95 to 00. A fixed pointed lug, as 149,disp0sed on the inner face of the dome 24, comes in contact with the cam-faces 126 of the dogs 124 and actuates said dogs. The ratchet-wheel 122, attached to the sleeve of the cents-wheel, has anumber of teeth corresponding to the number of numerals on said cents wheel, which in the machine shown is one hundred and twenty. A sleeve 127 is disposed on the extended sleeve of the cents-wheel between its actuating-disk 122 and the locking-pin 113. This sleeve is provided with a radial arm 128, which carries a spring pawl 129, which engages the ratchet-teeth of said actuating-disk 122 for turning said disk and actuating the cents-wheel. This radial arm is connected with a system of levers, hereinafter described, for lifting and depressing it under the action of the keys. A sleeve 131 is disposed on the rod 110, its right-hand end abutting against the sleeve of the cents-wheel and its left-hand end against the sleeve of the tens-dollar wheel. This sleeve carries a ratchet-disk 132, east with or fixed to it atits righthand end, the units-dollar wheel 130, castwith or fixed to it atits left-hand end, andasmaller actuating-disk 133, fixed on said sleeve between said units-dollar wheel and said actuating-disk. The disk 132 at the outer end of said sleeve shuts under the flange 123 of the cents-wheel and is engaged at regular intervals, as aforesaid, by one of the dogs 124, disposed on said flange. A sleeve 134 is disposed on the sleeve 131 between the two actuating-disks thereof and is provided with a radial arm 135, carrying a pawl 136, which engages the teeth of the intermediate actuating-disk 133. This radial arm is connected with a system of levers actuated by theunitsdollar keys of the keyboard, whereby said arm is lifted, turning said disk and actuating the units-dollar wheel. The periphery of said dollar-wheel is separated into twelve general divisions in the machine herein illustrated, each division having a series of ten numerals comprising all the digits arranged in order from 0 to 9, said numerals representing units of dollars, the total number of numerals shown being one hundred and twenty. The disks 132 and 133 have each anumber of teeth corresponding to the number of nu merals on said units-dollar wheel. This dollarwheel is provided on its left face with a flange 137, which carries a number of spring-dogs 124,similar to those on the flange of the centswheel and corresponding in number to the numberof general divisions on the units-dollar wheel. The teeth of these dogs pass through holes, as 148, in said flange and engage the teeth of one of the actuating-wheels connected with the tensrdollar wheel. These dogs are actuated by a lug, as 149, on the casing whenever the dollar-wheel passes from 0 to 9. A sleeve 141 is disposed on the rod 110 and abuts against the sleeve of the units-dollar wheel on its right-hand end and against the sleeve of the final numeral-wheel at its left-hand end. This sleeve carries at its righ thand end an actuating-disk 142, at its lefthand end a tens-dollar wheel 140, and between said tens-dollar wheel and disk 142 a smaller actuating-disk 143. The disk 142 at the outer end of said sleeve shuts under the flange 137 -of the units-dollar wheel and is engaged at regular intervals, as aforesaid, by one of the dogs 124, disposed on said flange. A sleeve 144 is disposed on the'sleeve 141 between the two actuating-disks thereof and is provided with a radial arm 145, carrying a pawl 146, which engages the teeth of the intermediate disk 143 for turning said disk to actuate the tens-dollar wheel. This radial arm is connected with a system of levers actuated by the tens-dollar keys of the keyboard, where by said arm is lifted, turning said disk 143, the sleeve 141 and the tens-dollar wheel 14:0 on said sleeve being rotated therewith. The periphery of this tens-dollar wheel is divided in the same manner as the periphery of the units-dollar wheel, and each of its actuatingdisks 142 and 143 has a number of teeth corresponding with the number of numerals on said wheel. This tens-dollar wheel is provided on its left face with a flange 117, which carries a number of spring-dogs 12%,the same as the dogs on the flange of the units-dollar wheel and arranged the same distances apart. These dogs are actuated in the same manner as the dogs of the units-dollar wheel by lug 149 on the casing, and the actuating-disk of the final numeral-wheel is thus turned one step whenever the tens-dollar wheel passes from 9 to 0. A sleeve 151, disposed 011 said rod 110, abuts at its right hand end against the sieeve 141 and atits left-hamlend against the locking-pin 114:. This sleeve is provided at its right-hand end with a ratchetdisk 152, similar to the ratchet-disk1t2,at its opposite end with thenumeral-wheel 150, and between said numeral-wheel and the disk 152 with a disk 153, similar to the disk 143 on the adjacent sleeve. The disk 152 shuts under the flange 147 of the tensdollar wheel and is engaged at regular intervals, as aforesaid, by one of the dogs 12 1, disposed on said flange, and is moved one tooth whenever the tensdollar wheel passesfrom 0 to 0? The periphery of this final numeral-wheel is preferably provided with one continuous series of numerals. The series illustrated extends from 0 to 110. Meansforactuating this wheel directly from the keyboard are preferably omitted when the machine is not required to register large sums at asingle registration. The flanges 123, 137, and 117 may be in the form of segments of flanges or lateral projections or pins sufficient to carry the dogs. A rod extends longitudinally from end to end of the dome 2-t, and spring check-pawls 116 are disposed on said rod opposite the several actuatingdisks 122, 133, and 143 of the cents, units-dollar, and tens-dollar wheels and opposite the disk 153 of the final numeralwheel. These eheek-pawls permanently engage said disks and preventaccidental turning of said wheels. Each of the numeral-wheels 120,130, and 110 is actuated directly from the keyboard by one or more levers, each of said levers being worked by any number of keys of the same denomination asthe wheel to which they impart rotation. In the ma chine illustrated in the drawings two separate levers and are employed for actuating the centswheel. A single lever is employed for actuating the unitsdollar wheel, and one lever is employed for actuating the tens-dollar wheel. A bent lever 200, provided with lateral studs 201, is pivoted in lugs 202 and 203, attached to the plate 33. The outer free end of this lever 200 is connected by an extended pivot-pin 204: with the lower end of a vertical rod 205, the upper end of which is connected with the radial arm 128, which carries the spring-pawl 129 for engaging the actuating-disk ot' the cents-wheel. A torsional spring 206, fastened at one end to the lug 202 and at the other end to one of the studs 201, acts torsionally to depress the inner free end of said lever 200, restoring it to its normal position and retracting the pawl 129 on the actuating-disk 122. Thelever 1601s worked bythecents-kcysfrom 5 to 30, and thelever 170 is worked by the cents-keys from 35 to 95, inclusive. Thelever 160 is yokeshaped and pivoted on one side to a stud 161 at one end of the casing and on the otherside to a stud 162, attached to a dependent arm 163, connected with the end 111 of the dome 24. The inner arm of the yokeshaped lever 160 is extended rearward past the'stud 162 to a point slightly beyond the periphery of the actuating-disk 122 of the cents-wheel. This arm is provided at its inner end with a lateral arm 161, extending toward the left at an angle to the hotly of the yoke. The inner end of this short arm terminates under the right-hand end of an extended pivot-pin 204, which connects the rod 205 with the depressing-lever 200, being thus in position to lift said rod and lover when worked by the keys, as hereinafter described. The yoke-shaped lever160is provided with a cross-bar 165, disposed in position to be worked by the ten, twenty, and thirty cents keys, the outer end of said lever being in position to be worked by the ti ve, fifteen, and twenty-live cents keys. The lever 170, also for actuating the centswheel, consists of a yoke pivoted at one end to a lug171, projecting from the arm 163, and at the other end to a lug 172 at the left-hand end of the case. The outer end of this yokeshaped lever is in position to be worked by the thirty-five, forty-five, fifty-live, sixty-five, seventy live, eighty-live, and ninety-five cents keys, and it is provided with a cross-bar 173, disposed in position to be worked by the forty, fifty, sixty, seventy, eighty, and ninety cents keys. An arm 17% extends rearward from the crossbar 173 and terminates under the lefthand end of the extended pivot-pin 201, which connects the depressing-lever 200 with the rod 205, said rod being pivoted at its upperend, as aforesaid, to the radial arm 12S, carrying the pawl 120, which actuates the disk 122 on the sleeve of the cents-wheel. Theinner end of this arm is then in position to elevate the mechanism for turning the actuating-disk of for registering the lower and higher numbers of cents. The lever 180 for actuating the units-dollar wheel is also in the form of a yoke and is pivoted at its opposite ends to the studs 181 and 182, disposed at the ends of the casing. The front of this leveris in position to be worked by the entire row of units-dollar keys, and it is provided with a rearwardlyextending arm 183, which is connected at its inner end by a vertical rod 184 with the radial arm 135, carrying the pawl 136, which engages the actuatingdisk 133 of the units-dollar wheel 130. This lever is restored to its normal position after being worked by a unitsdollar key by springs 185 and 186, attached to the end of the fulcrums 181 and 182, cugaging pairs of pins 187 and 188 on the ends of said yokeshaped lever. The lever 190 for actuating the tens-dollar wheel is also in the form of a yoke and is pivoted at its opposite ends to studs 191 and 192, disposed at the inner ends of the casing. The front of this yoke is in position to be actuated by anyof the keys of the tens-dollar row and is provided with a rearwardly-extending arm 193,which is pivoted at its inner end to a vertical rod 194, said rod 194 beingconnected at its upper end with the radial arm 145, which carries the pawl 146, which engages the ratchetdisk 143 for actuating the tens-dollar wheel 140. This lever is restored to its normal position after being depressed by one of the tens-dollar keys by means of springs 195 and 196, having their inner ends disposed in slots in said studs 191 and 192 and their outer ends placed between pairs of pins 197 and 198 in the ends of said lever. The levers 160 and 170 are bent upward and downward, as shown in Fig. 3, to avoid interfering with other mechanism hereinafter described, and the lever 180 is bent upward, as shown in said figure, to avoid interference with the levers 160 and 170.

In the machine herein shown the keyboard is arranged with four rows of keys, the first or lower row 210 representing cents in odd multiples of five from 5 to 95, the second rows of keys 220 representing cents in even multiples of ten from 10 to 90. The third row 230 represents units of dollars in all the digits from 1 to 9, and the four row 240 represents dollars in multiples of ten from 1O to 100. The several rows of keys are arranged 'on different planes, one above the other, in steps. The key-stems are an gulariu shape and extend through slots in the stepped plate 23, their lower ends projecting through and being guided by slotted bars 211,221,231, and 24l,respectively. Thestems,beingangular in cross-section, are prevented from turning in their slots. Each stem is provided at its upper end with the usual cap-plate containing the index number or character of the key. These plates are provided on their undersides with stop- collars 212, 222, 232, and 242, which come in contact with the stepped plate 23 when the keys are depressed and determine the stroke thereof. A yoke-shaped frame 250 is pivoted on interior lugs 251 and 252 at the opposite ends of the frame. Springs, as 253, are disposed in the lugs 251 and 252 and engage at their free ends pairs of pins, as 254, on said yoke. These springs tend to swing the yoke upward and hold the front bar thereof in contact with the lateral studs 213, attached to the several key-stems of the lower row of keys 210. This spring-yoke thus acts to restore any of the keys of said lower row to their normal positions after being depressed. The several stems of the lower row of keys 210 are provided with lateral pins, as 214, which extend forward from said stems at a proper elevation to engage the front bar of the drawer-releasing lever and depress said lever the requisite distance for releasing the drawer Without; interfering with the guidebars 211, 221, 231, and 241. These key-stems are also provided lateral front pins, as 215, which are disposed on their several stems in proper positions to engage the lever 160 or the lever 170, being placed at different heights in said stems, so as to depress said levers the requisite distances for registering the sums indicated on the respective keys of said lower rows. The stems of the keys 220 belonging to the next row are provided with lateral pins 223, all of which are disposed in the same plane in proper positions to engage the crossbar 54 of the drawer-releasing lever 50 and depress it a sufficient distance to release the drawer without interfering with the guideplates for guiding the lower ends of the keystems. These key-stems are provided with back pins, as 224, which are disposed in position to engage the cross-bar 165 of the lever 160 or the cross-bar 173 of the lever 170, said pins being placed at different heights on the different stems, so as to depress said levers different distances for registering sums indicated on their respective key-plates. These key-stems are restored to their normal positions, after being depressed, by springs 225, which are attached at their inner ends to a fixed bar 226, extending from end to end of the machine. These springs bear upward against pins 227 on said stems. These stems are provided with stop-pins 228, which determine the extent of their upward movements under the action of the retracting-springs. The stems of the keys 230 belonging to the third row are provided with front studs 233, disposed in the samehorizontal plane in proper position to engage the cross-bar of the drawer locking and releasing lever 50 and depress said levers the requisite distance to release the drawer without interfering with the keys of the fourth row.

lower guide-bars of the key-stems. The stems of these keys are provided with back studs, as 234, which are disposed in positions to engage thelever180foractuating theunits-dollar wheeh These back studs are also placed at ditferentheights, so as to depress said lever different distances for registering the respective sums indicated on the keys of the third row. These stems are provided with lateral studs 235, which are engaged by lifting-springs 236, attached to the cross-bar 226, said springs serving to restore any of said keys to their normal positions after being depressed. These stems are also provided with studs 237 for limiting the extent of their upward move ments when retracted by the springs 236. The stems of the fourth row of keys 240 are provided with front studs 243, disposed in position for engaging the bar 56 of the drawer locking and releasing lever 50, said studs being disposed at the proper elevation for depressing said lever a sufficient distanceto release the drawer without interfering with the guide-plates at the lower ends of the keystems. These stems are provided with back studs, as 244, disposed in positions for engaging the lever 190 for actuating the tens-dollar wheel. These studs are disposed at different heights on the different stems, so as to depress said lever ditferent distances for registering the respective sums indicated on the These keys are restored to their normal positions after depression by springs 245, attached to the fixed bar 226 and engaging lateral studs 246 on said stems. These stems are provided with stops 247 to determine the extent of their upward movements when restored to their normal positions by the action of the lifting-springs.

To avoid false registrations by the depression of two keys simultaneously, locking mechanisms are employed, which when one key is depressed cause the locking of all the other keys of the keyboard until the depressed key reaches the end of its downward stroke. These locking mechanisms, as herein shown, comprise a locking mechanism which operates upon the different rows of keys and a locking mechanism which operates upon the several keys of the respective rows. The locking mechanism for the rows of keys consists of a broad movable plate 260, extending from end to end of the keyboard and supported by upright arms 261 and 262, pivoted on studs, as 263 and 264, at the opposite ends of the case. This plate is of a width which slightly more than spans the space between the first and fourth rows of keys, and it is provided with two series of slots 265 and 266 for the passage of the stems of the keys 220 of the second row and of the stems of the keys 250 of the third row. Each of these slots is of a width to permit the stems to fit and slide therethrough, and the two series of slots 265 and 266 are of slightly-greater distance apart than the distance between the stems of the said two rows of keys. The stems of the keys of the row 210 are provided on their inner faces with notches 267. The stems of the second row are provided with rear notches 268. The stems of the third row are provided with front notches 269, and the stems of the fourth row are provided with front notches 270. The said notches are all on the same horizontal plane when the keys are in their normal positions and are approximately in the same plane with the locking-plate 260. These notches are beveled upward to permit the key-stems to slide through the slots of the locking-plate and against the sides thereof, said beveled faces serving as wedges to shift said plate when a key is depressed and swing it out of the notches of the third and fourth rows of keys and into the notches of the first and second rows of keys for locking them, or Vice versa. A locking-plate 280 extends from end to end of the keyboard between the first and second rows of keys and is of a width slightly greater than the space between the stems of the keys of said rows. Thislockingplate is supported on arms 281 and 282, pivoted on studs 283 and 284 at the ends of the case. The stems of the first row of keys are provided on their inner faces with notches 285 and the stems of the second row of keys are provided with notches 286, said notches 285 and 286 being on the same horizontal plane throughout the keyboard and in substantially the same plane as the oscillating plate 280. These notches are also beveled upward,and said plate when swung to the right engages the notches of the first row and when swung to the left engages the notches of the second row. A third locking-plate 290, similar to the plate 280, is disposed between the third and fourth rows of keys, being supported on arms 291 and 292, which are pivoted on studs 293 and 294, disposed at the inner ends of the casing. This plate also ex tends throughout the length of the keyboard and is of a width slightly greater than the space between the third and fourth rows of keys. The stemsof the keys of the third row are provided with back notches 295 and the stems of thekeys of the fourth row are provided with front notches 296, said notches 295 and 296 being in substantially the same plane with each other and with the locking-plate 290 and being beveled upward to permit the stems to pass downward. This locking-plate when rocked forward engages the notches of the stems of the third row of keys and when rocked backward engages thenotches of the stems of the fourth row of keys, locking the third row in the one position and the fourth row in the other. The stem of each key of the front row is provided with two releasing-notches 300 and 801, the notch 300 being disposed at a sufficient distance above the notch 267 to come opposite the locking-plate 260 when the key is fully depressed, whereby said plate is free to move and the several keys are released. The notch 301 is disposed in such position above the locking-plate 280 as to come opposite the edge of said plate when the key is fully depressed, thereby permitting said plate to oscillate freely, releasing the second row of keys. The stems of the second row of keys are provided w th notches 302 and 303, the notch 302 being disposed a sufficient distance above the plate 200 to come opposite said plate when the key is fully depressed, whereby the plate is free to move and the keys, which have been locked thereby during the operation of depressing the given key, are released. The lower releasing-notches 303 are disposed a sufficient distance above the locking-plate 280 to come opposite the inner edge thereof when one of said keys is fully depressed, whereby said oscillating plate is free to oscillate and the keys of the first row are unlocked. The stems of the third row of keys are provided with releasing-notches 304 and 305, the releasingnotch 30% being disposed a sufficient distance above the locking-plate 260 to come opposite the plane of said plate when the keys are fully. depressed, whereby said plate is released and the keys unlocked. The notches 305 are disposed a sufficient distance above the locking-plate 290 to come opposite the said plate when the keys are fully depressed, whereby said plate is released and the keys of the fourth row unlocked. The stems of the fourth row of keys are provided with releasingnotches 306 and 307, the former being disposed a sufficient distance above the locking-plate 290 to release said plate and unlock the keys of the third row when a key of the fourth row is fully depressed and the notch 307 being disposed a sufficient distance above the plate 260 to release said plate and unlock the first and second rows of keys when the key for the fourth row is fully depressed. All the releaslng-notches are beveled downward to permit the keys to be readily retracted. A partial depression of one of the keys of the first row 210 swings the locking-plate 260 backward and causes it to engage the locking- notches 269 and 270, whereby the third and fourth rows of keys are locked. The same depression swings the locking-plate 280 into thelocking-notches 28G, whereby the second row of keys is locked. XVhen the depression of one of the first row of keys, as aforesaid, is completed, the locking-plates are released and the several rows of keys are unlocked, as hereinbefore explained, by means of the releasing-notches on the f ully-depressed key. A partial depression of one of the keys of the second row 210 causes a backward oscillation of the locking-plate 260, whereby the third and fourth rows of keys are locked in the same manner as by the partial depression of a key of the first row, and by the action of the same key-stem the lockingplate 280 is swung forward, engaging the notches 2S5, whereby the first row of keys is locked. WVhen the given key of the second row is fully depressed, its releasingnotches unlock the keys of the other rows, as before explained. Vhen a key of the third row 230 is partially depressed,the oscillating plate 260 is thrown forward and engages the locking-notches 267 and 26S, whereby the first and second rows of keys are locked, and by the same partial depression of the same stern of the third row the locking-plate 290 is swung backward and caused to engage the notches 296, whereby the fourth row of keys is locked. \Vhen the given key of the third row of keys is depressed to its full extent, its releasingnotches release the locking-plates and unlock the other rows of keys. hen a key of the fourth row 240 is partially depressed, it moves and holds the lockingplate 260 in its forward position, whereby said plate engages the notches 267 and 268 and the first and second rows of keys are thereby locked. The same partial depression of the given key of the fourth row swings and holds the locking-plate 290 in its forward position and causes it to engage the notches 295, whereby the third row of keys is locked. When the given key of the fourth row is depressed to its full extent, its releasing-notches release the locking-plates and unlock the keys of the other rows. The locking mechanism for locking different keys of the same row is adapted to operate when one key of a row is partially depressed in such manner as to lock all the other keys of that row until the key is fully depressed. Pockets 310, 311, 312, and 313 are disposed immediately beneath the stepped plate 23 of the easing and extend longitudinally of the keyboard in planes passing through the several rows of key-stems, the said stepped plate serving as a top for the several pockets. These pockets are each provided with vertical slots 31a, through which the key-stems play. Each ofthe key-stems 320 is provided on its opposite sides near its upper end with cams 321, having downwardly-incliued faces 322 and upwardlyinclined faces 32%. Recesses 323 are formed on the key-stems between the cams and the stop-collar of the key-plate. Slides 330 are placed in each of the pockets, one between each two of the key-stems. Each slide is provided with a recess 331, through which a key-stem passes. The extreme length of each slide is equal to the distance from center to center between any two of the keys, and the length of the slide from one end thereof to the end of the recess is equal to the distance from the straight face of the cam of one key to the opposite face of a stem of the next key. When a key is depressed, as shown in Figs. 13 and 1%, the cams 321 thereof descend into one of the slots 31% and one of the inclined faces 322 enters the recess of one of the slides and the other inclined face 322 comes in contact with the straight end of the adjacent slide, said inclined faces acting as a wedge to separate said slides a sufficient distance to permit the cams 321 to descend. This separation of the slides adjacent to the depressed key presses said slides and all the other slides of the row in contact with the narrow stems of the other keys and locks said keys, there being no room for the descent of another cam until the depressed key reaches the extent of its downward stroke. In such case the recesses come opposite the plain and recessed ends of the adjacent slide. When the key is thus fully depressed, another key may be depressed for effecting a partial registration in the same row of keys. When the second key is depressed during the depression of the first key, the slides are separated in the same manner by the second key, one of said slides entering one of the recesses 323 in the first key.

The operation of this apparatus is as follows: In Fig. 1 the reading-slot shows an aggregate of registrations of $987.45, the last registration, as shown by displayed indicating-plates, being $179.40. Supposing it is desired to register eight dollars and fifty-five cents, the key of the units-dollar row having the index 8 is depressed. In its descent the lug 233 of the key-stem comes in contact with the yoke-shaped lever 50, whereby the dogs 58 and 59 are raised out of contact with the teeth 41 and 42 and the drawer released. The spring 43 then throws out the drawer. The depression of the yoke-shaped lever 50, which controls the drawer-locking mechanism, depresses the front end of the lever 99 and raises the rear end thereof. This lever 99 then swings back the rocking frame 90 by contact with its dog 97, and the levers 71, supporting the rods which carry the indicatingplates of the last registration, are released from the top bar of said rocking frame and fall into their normal positions on the rod 91. The lower end of the stem of the eight-dollar key comes in contact with its lever 71 and raises the rear end thereof until it passes the cam-face of the rocking frame 90, and said frame then swings forward and latches under said lever and holds it in an elevated position. This elevation of said lever 71 throws up into displayed position two of the indicator-plates 76, each containing the eight-dollar sign, said plates showing in opposite directions through the windows 30 and 31.

When the releasing-lever 99 passes the dog 97 and the rocking frame 90 swings forward, it causes the bell-hammer 103 to strike the bell 104. In the descent of the eight-dollar key the locking-notch 269 on the stem thereof oscillates the locking-plate 260 toward the first and second rows of keys and causes itto engage the notches 267 and 268 of said first and second rows and lock the keys thereof, and the locking-notch 295 on said stem of the eight-dollar key swings backward the lockingplate 290 into the locking-notches 296 of the fourth row of keys and locks all of said keys. In its descent this key also bythe wet ging action of its cams or broadened shank 321 slides the slides in the pocket 312 and locks the other keys of the same row. When the eight-dollar key is finally depressed, the keys of the'same row are released by the recesses 323, and the keys of the other rows are released by the releasing-notches 304 and 305 of said key-stem. The fifty-five-cents key is then depressed, the eight-dollar key being held down during such depression. The action of the fifty-fi ve-cents key upon its lever 71 throws the fifty-five-cents plate into position opposite the windows 30 and 31 in the lower plane of display, the said plates being held in displayed position by the action of the rocking frame 90, which latches under the inner end of the lever '71, actuated by the fifty-five-cents key. During the act of depressing this cents-key the keys of the other rows are locked by the action of the locking- plates 260 and 280, and the keys of the same row are likewise locked by the action of the slides of the pocket 310. This temporary locking of the other keys during the depression of one of them prevents false registrations, which might occur by the depression of two or more keys simultaneously.

The registering act-ion of the keys depressed as aforesaid will now be described. The depression of the eight-dollar key causes its pin 234 to come in contact with the lever 180 and actuates said lever a sufficient distance to turn the actuating-disk 133 on the sleeve 131 of the units-dollar wheel 130 a distance of eight teeth, thereby moving said wheel from the numeral 7 of one of its general divisions to the numeral 5 of its next general division. The units-dollar wheel during this movement passes from 9 to O, and one of the dogs 124, attached to its flange, engages the actuating-disk 142 on the sleeve of the tens-dollar wheel, whereby said wheel is actuated a distance equal to one numeral of its periphery, the 8 being carried out of the reading-slot and a 9 brought into position therein. \Vhen the fifty-five-cents key is depressed, the lateral pin 215 on the stem thereof engages the lever 170 and depresses it a sufficient distance to cause the pawl 129 to rotate the actuating-disk 122 a distance of eleven notches. This movement of the actuatingdisk causes the cents-wheel attached to the sleeve of said disk to shift the numeral from the i'eading slot and bring 00 into position therein. During this movement of the cents-wheel one of its dogs 124 comes in contact with a pointed lug, as 149, on the ease, whereby said dog is depressed and made to engage the actuating-disk 132 of the unitsdollar wheel 130 and said wheel is moved forward one notch, thereby shifting its figure in the reading-slot from 5 to 6. The aggregate registrations appearing in the readingslot will then be $996.00. After each registration in which two or more keys are used the several keys are released one at a time in succession and are restored to their normal positions by the retractirig-springs, hereinbefore described. After each registration the money-drawer is pushed in and caught by the dogs and remains locked until a key is pressed for the next registration.

The register shown in the drawings has a capacity of twelve thousand, and when this exact sum is reached the numeral-wheels are all at 0. In case the last individual registration is more than suflicient to carry the wheels past the zero-points, the excess thereof will appearin the reading-slot. It is obvious that the capacity of the machine may be varied byincreasingor diminishing the number of registering-wheels and their connecting mechanisms or by varying the divisions on said wheels.
