CASH-REGISTER.

Specification of Letters Patent. Patented June 27, 19] l Application filed September 4, 1809. Serial No. 516,301.

To all whom it may concern:

Be it known that I, \Vmnmn SUMNER, a subject of the King of Great Britain, and resident. of Liverpool, England, have invented certain Improvenuants in Cash-Registers, of which the following is a specification.

The present invention relates to certain improvements in cash registers, and comprises certain devices for setting the mechanism in position to make the desired record; by means of levers or handles, means for communicating the motions of such setting devices to the printing wheels and totalizers, means for exhibiting tablets'for indicating to the cashier and customer the amount f the sale recorded, means for controlling the till, and means for causing the several devices above referred to, to cooperate with one another.

Referring to the drawings; Figure 1 is a front: elevation of the machine, showin" the setting handles and drums, portions the casing being removed. Fig. 2 is a front elovatim. showing the operating lever-frame, portions of the casing and of the mechanism being removed. Fig. 3 is a sectional end view, showing the schcn'ie of chains by which the motions of the setting drums and the operating lcvcr-fran1e are transmitted to the several devices of the machine. Fig. 4 is a rear elevation of the machine. Fig. 5 is at sectional end view, showing the paper record printing device, and Fig. (3 is a plan of this device. Fig. 7 is a sectional end view, showiug the setting drum locking device, the till locking device. and. device for fccdin forward the totalizcr. Fig. 8 is an end view of the machine, showing a check action for controlling the movements of the operating lever. Fig. 2) is ascctional detail of the totalizcr train. l ig. '10 is a front view of tliiijadvcrtising mechanism employed on the nnchinc, Fig. 11 an end view, Flglfl 12 a fl.( it view, of the outer casing of the niachii'ie. Fig. 13 is an end view and Figfill a rear view of the casing.

The setting devices comprise two drums, 1. can-h rcm'csenting different denominationsot' Milli, such as pence and shillings. To these drums are coupled the lpvers 2. projecting through slots in the machine casing. the setting being ctlertcd by moving these lovers in their slots. Suchmovcmcnt of the setting drums is conununit-atcd or is permitted to be communicated to the several devices of the machine by means of chains, as hereinafter described. After the several devices of the machine have been set to afford a record, the operation is completed by what may he termed the operatmg lever, 3, as will be doscribed. The drums 1 arefixed on sleeves 4-. Also fixed on the sleeves 4 are pulleys 5, 13.

From these drums and pulleys chains are led to the several devices of the machine. The operating lever 3 is attached to the rocking shaft 7. Fast on shaft 7 are cranks 8. From the ends of cranks 8 the frame-bars 9 load to bar 10, the ends of the latter traveling in slots 11 in the end plates 12.

The paper record mechanism is a scparable unit, comprising the plate 13 carrying the paper spools 14. The plate 13 is attached to the pillar 15 on. sleeve 16 by the catch. 17, and is supported by the trunnion 18 on the bearer bar 19, one end of this bar being attached to sleeve 16 while its other cud rests upon the cross-piece 20 of the frame-bars 9. The trunnion 18 is located under the sockebpiece 21 on the bar.19. By undoing the catch 17 the paper record device may be removed as a whole, through the door 136, for examination and removal of the printed record. The impression of the printing-wheels 22 is taken by the paper strip :23 at each depression of the 0 rating lever '3, the platen 24 being fixe to the plate 13. The bearer-bar 19 follows the downward movement of the cross-piece 20 until the paper and platen rest upon the printing wheels, the impression being made )y the terminal downward motion of the cross-piece 20 heingcommunicated to the bar 1!) by the spring 25. As the paper record device rises again, its ratchet wheel 26cmages the pawl 27 so that the paper strip 23 is fed forward tor the next record. The wheels 22 are inked by rollers 28 carried on the rocker 29, which latter is linked to an arm 30 on sleeve 16. The printing wheels are respectively carried on two sleeves 31. which also carry pulleys 32. From the pulto s 32 chains 38 lead to the drums 1, to which they are attached, and thence to the pulleys 34 of the totalizer. The printing wheels are returned to zero by chains 35 and springs 36 attached to pulleys 6.

The numeral disks 37 for indicating through apertures 38, the, position in 'which the drums 1 are set, are rotated by chains 39 attached to alleys 6, springs 40 serving to return the he 37 to zero.

The totalizer comprises four numeral disks, 41, 42, 43, 44, representing pence, shillings, pounds, and increments of twenty pounds, respectively. The disks 41, 42 rotate ull spindle 45, the disks 43, 44 rotating on the hollow shaft 46 carried in bracket 47 which is fixed to the sta rods 47. The pawl arms 48 which turn t 1e pence and shilings' disks are carried on sleeves 49, on which the pulleys 34 are fixed. The pins 51 of the pawls 52 are normally out of gear with the lesser ring of teeth on the disks 41, 42, so that after the pulleys 34 are turned by the sleeves 49 and chains 134, the pawls and pins 51 move freely backward over said teeth. Said pins are brought into gear with the teeth of the disks by the links 53 connecting such pawls with sleeves 54. From sleeves 54 the slack chains 55 lead to nipples 56 on cross-piece 20.

In operation, when the drums 1 are set as required, the chains 134 and sprin s 135 rotate the sleeves 4t), and the paw arms 48 travel. backward over the teeth of the disks 41, 42 each to the required tooth. In this action the arms 48 have-by the links 53- also turned the sleeves 54, so that the latter have each wound up a portion of the slack chains 55. The operating lever 3 is then dopressed, the cross-piece 20 descends, the chains 55 tighten and then turn the sleeves 54, until the amount of slack chain wound thereon is unwound,-and in so turning the sleeves 54 the links 53 draw the pins of the pawls 52 into gear with the teeth of the disks 41, 42. The pawl-arms 48 are thus, during the downward movement of the lever 3, turned forward the same distance which they were turned backward by the drums 1, and in this forward n'iovemrnt of the pawl arms they carry with them the disks 41, 42, and so add the amount to the total sn'm.

The carrying forward of a shilling from the pence disk tl. to the shillings disk 4-2 il effected by the trip lever 57 on the loose sleeve 58. pawl 59 on (his lover gears with the larger ring of teeth on disk 42. the other end, (it), of the lever, being connected by a spring (51 with the bar U2." The lever end 60 is also engaged by the detent (33, which is influenced by sprii'ig 11;") attached to sleeve 116. At each revolution of disk 41 a projection (54 thereon presses the detent. Gil on of contact with the lever 57, allowing the latter to be canted to the stop piece 50 byits spring 61, so that its pawl 55) is drawn backward over one tooth on the disk 42. As the lever 3 rises, a strut (if) on bearer-bar it) raises the lever 57, so that the latter rotates the disk '42 one tooth and also retingages itself with the detent 63. At. each revolution of the disk 42, the disk 43 is fed forward. one tooth by a projection or, on the disk 42 an aging a tap'pet rod 67 on the sleeve (58. A so on the sleeve 68 which is seated on the shaft. (38 is the pawlarm 69 gearin with the teeth of the disk 43, a s ring 70 e ecting the forward movement 0 such pawl-arm. (1on1 lete revolutions of the disk 43 are trans nitted to the disk 44 by the tappet 71, pawharm 72 and spring 73,

113 are non-return pawls, and the disks are caused to recoil thereto by the bent springs 114.

The totalizcr may be read 0H through the doorway 137.

The tablets 74 by which the amount of the sale is exhibited through a ertures 75, are as follows. The ence tab ets are twentythree in number, caring numerals indicating from id. to 114d. while the shillings tablets are twenty in number. These tablets are pivoted on pins 76 and rest upon pins 77. The tablets are canted upward into their. visible osition as follows. From the pulleys 5, c wins 78 pass to blocks 79 which slide upon pins 80 carried in the bar 62, that is the blocks are drawn forward by the chains 7 8 against the springs 81. Above the blocks 7%) are similar .blocks 82 sliding on square rods 83 in the upper ends of the frame-bars 84. The bars 84 are slotted and possess vertical movement upon the pins 80, 85, this vertical movement being due to the rise and fall of the bar 10, the set-pins 86 in the ad j ustabl'e ends 87 of the bars 84 resting on the bar 10. The blocks 79 are connected to the blocks 82 by springs 88. Fork-pins 80 rise from the blocks 79 to limit the travel of the blocks 82. The blocks 82 carry lifter 100 arms 90 by which the tablets are raised to their visible position, as follows. \Vhen the blocks 79 are drawn outward by the chains .78 a distance proportional to the movement of the drums 1, the blocks 82 cannot immediately follow, because their lifter arms 90 are behind the rearmost tablet or are beta een two tablets, aecordingl as they were last left. Consequently the plus 83 carrying the blocks 82 must be lowered to allow the lifter arms 90 toescape from and )ass bencath the tablets, and this is efiecte by the depression of the lever 3, allowing the bars 84. to fall and carry with them the rods 83 and blocks 82. The blocks 82 then follow the blocks 7!) until arrested by the forks 89 of the blocks 79, when the lifter arms 90 will be inonediatcly under the specific tablets which indicate 'the sum to be recorded. \Vhen the lever B rises, the bars 84 are raised by the bar 10, carrying with them the rods 83 and blocks 82, so thatthe lifter arms 90 raise the tablets and hold them against the abutment bar 91 until the next depression oi lever 3. The lifter arms 90 are elastic and keep the tablets against. the bar 91, this clasticity serving-when the blocks 82 are lowcred-to tip the tablets so that they fall by gravity into their horizontal positron.

To lock the drums 1 in theirset ipdsitions, 139

their sleeves 4 move lengthwise on the spindles 92. '1 0 afford this movement the levers 2 are tulcrumed on the spindles 92 and coupled to the drums 1 by studs 93. A sto piece 94 abuts against the bar 97. Eac drum 1 possesses perforations 95 corresponding in number with the setting motions of the drums. When the drums are moved sidewise the detents 96 on the bar 97 enter these perforations, and the drums are held in this locked position by the inclined bars 98namely as the lever descends the, bars 98 push the drums sidewise so that one of their respective perforations 95 engages in the detents 96. These bars 98 are secured to bars 9 and are carried downward by the cranks 8 by means of the lever 51; and the sleeves 4 being \slidable on shafts 92, are ].)res-'ed into normal position relative to said shafts by means of said bars 98, by which means'said drums are secured in engagement with the detents 96 when the lever 3 is de- 'u-essed; the normal position of the arms being retained by springs 90. The drums 1 may be unlocked from the detents by moving lever 3 laterally when the lever 3 is raised, whereupon the drums return to zero and to their normal position of the shaft 92, by means of the springs 99, attached to pulleys t]. The drums are adapted to be unlocked, by the cams 100 on the shaft 101, when the cash drawer is withdrawn, by contact of said cams with the outer flange of the drum. p, On the shaft 101 is the arm 102, against which the back of the drawer 103 abuts, the shaft 101 being turned by springs 10% which connect the arm 105 with the bar 106. W'lzen the drawer is closed the cams 100 are clear of the drums 1, allowing free movementof the latter lengthwise of the shaft 92, when the drawer is withdrawn the cams 100 engage the drums tomove them in the direction of their axes and retain them against rotation until the drawer is closed. The drums 1 cannot therefore return to zero while the drawer is open or while the lever is depressed.

The bars 9 and'98,the cross piece 20, and the bar 10 constitute the operating frame. which is actuated vertically by the lever 3,

through the.1nedium" l5f the shaft 7 and cranks 8.

The cash drawer 103 is released by the descent of the bar 10, the latter striking the end of detent lever 107 fnlcrumed on the bar 106, the other end of this lever engaging striking plates 108 on the drawer 103.

To insure complete downward and lipward. movementsof the lever 3, when once initiated, a spindle 109 is pivoted on the. and of bar 10, and passes through a eylin drical aperture in the end of check-lever 110, the other end of this lever being controlled by the bow-spriru 111. The lever 1.10 is tippedfinto eitheco? the two positions shown, by the stop pieces 112 on the spindle 109'. The effect is, that the angle of the check-lever relatively to, the axis of the spindle 109 determines whether the latter passes freely through the vlindrieal aperture in the check-lever or is gripped thereby. The recovery or upward movement of the lever 3 is assisted by thespring 138.

An advertising device is moved at each operation of the lever handle 3, as follows. The advertisements are set forth on a sheet of linen or the like, 117, arranged to wind on and off rollers 118, 110 jourrialcd in the plate 120. The advertisements are exhibited through the window 121 in the back of the reister case. The roller 11% is a spring ro ler of the usual type, and the roller 119 is rotated step by step by the pawl 122 which gears the ratchet 123 and is carried on the pawl arm 124, the latter lieing coupled by a chain 125 with the crank 126 on one end of the shaft 7. The sheet 117 is wound up on the spring roller 118 and is drawn therefrom by the roller 119, and when the sheet has been wound on the roller 119 the latter is released-as hereinafter described-so that the sheet is again woun on to the spring roller 118, and the stepby step unwinding motion again commenced." A detent pawl 127 is frictioi'ially mounted on its pivot, so that it will remain in whichever position it is placed in. This detent 127 is pressed into engagement with the ratchet 123 at each movement of the lever 124 by the spring 128. on the latter, and is pressed out of engagement by the rotation of the ratchet. In order that the detent 127 may he held clear of the ratchet, to allow ofthe sheet 117 being wound back upon the spring roller 118. a. pinion 129 upon the said ratchet gears with a messenger wheel 131), and fixed in this wheel is a pin 131, which, when the sheet is -wound upon .the roller 11 8, engages the detent 127 and holds it away from the ratchet. As the pawl aim 12-1 has now returned to its position of rest, its spiking 128 no longer presses upon the detent 127, so that the roller 118, pinion 129 and messenger wheel 130 are ..free to recoil while the s" ring roller 118 is winding up the sheet 11 i \Vhen the sheet 117 is re-wound on the richer 118, a pawl 132 drops into a. notch 133 in the roller 11!) ,1 which has been uncoverediby the unwindin sheet, and so serves as a limit to the rewin in of the sheet on the roller 118.
