Application filed manta, 1915. "seriaiNo. 17,824.

To all whom it may concern:

Be it known that I, WILLIAM SUMNER, a subject of the King of Great Britain, and a resident of Liverpool, England, have invented certain new and useful Improvements Relating to CashRegisters, of which the following is a specification.

This invention relates to improvementsin cash registers, the movement of the various devices in which, such as the sales amount totalizer, sales record printing mechanism, and sales indicating tablets, are operated by means of flexible bands coupling such devices to the main setting drums of'the machine.

According to this invention, the movement of certain of the various devices in the machine is obtained from the main setting drums by positively coupling drums or the like. on the spindles of such devices to the main setting drums by means of flexible bands or the like, the rotary movement of the devices in either direction being thus positively obtained. Further features of the invention relate to an improved arrangement and construction of the key mechanism of the machine; to means whereby the. operation of the various parts of the machine in recording a sale is effected by the action of a control key, or keys, which releases a Spring controlled cash drawer, the opening movement of which permits the main setting drums to rotate to their determined positions and so position the coordinated devices; to'

means whereby the carrying over of an increment'from one numeral disk in the totalizer to the next higher disk in value is effected on the terminal closing movement of the drawer and after the main operation of the totalizer has been eifected; and to means whereby a no sale tablet is displayed if no coin keys have been depressed and when the drawer is released by the control key, without any special no sale key being provided.

To operate the machine, the keys for the particular sale record are depressed; these act to limit the subsequent angular movement of the setting drums. Adcontrol key is then depressed, releasing the spring controlled drawer, which in opening permits the angular movement of the setting drums, and positions the various devices, displays the sale tablets, and prints the sale record, the closing of the drawer returning the setting drums, releasing the keys, operating the summing action of the totalizer, and re-setting the printing mechanism.

A cash register in accordance with this invention is illustrated diagrammatically in the accompanying drawings, in which Figure 1. is a side view, in section, of the register, Fig. 2. beingv a side View, in elevation, looked .at in thesame direction as Fig. 1, and Fig. an elevational rear view, partly in section. Fig. 3 is a fragmentary plan of the control keys. Fig. 4:. is a fragmentary side view, partly in sect-ion, showing the method of operating the increment carry-over of the totalizer and the printing release mechanism from the cash drawer. Fig. 5. is a frage mentary plan view of the totalizer train, and .Fig. 6. a cross section of Fig. 5. in the zone of the pence unit. Figs. 7. and 8. are a fragmentary plan and sectional end view of the pence unit of the totalizer, showing the trailing pawl connection. Fig. 9. is a side view of the printing mechanism, and Fig. 10. a fragmentary plan of Fig. 9., in section, showing the method ofcarrying the type faced disks from concentric sleeves on the print ing mechanismspindle. Fig. 11.is a perspective detail, to a larger scale, showing the releasing and controlling catch mechanism of the cash drawer. Fig. 12. is a fragmentary plan of the control mechanism. for preventing reversed movement of the drawer. Fig. 13. is aperspective view, illustrating the se quential arrangement of the cams for operating the totalizer. Fig. 1.4. is a section, on an enlarged scale, of a key bank showing the no sale tabletindicating mechanism, Fig. 15. being a fragmentary detail of the lower part of the keybank shown inFig. 14., and

Fig. 16. is a rear view of the lower part of one of the key banks and the inner locking plate. Fig. 17. is a rear view of thesale tablet indicating mechanism,Fig. ISQbeing a fragmentary perspective view showing the sale tablet lifting gear. Fig. 19. is a perspective view of two units of the totalizer train, illustrating the means for carrying over an increment from one unit drum to the next of higher value, and Fig. 20. is a front view of the cash register.

The setting device comprises, say, four drums 1, 2, 3, 4, for English coinage, corresponding to pounds, shillings, pence, and farthings, but for other denominations of coin the number of setting drums wouldbe varied accordingly. These setting drums are fixed to sleeves 5 mounted loosely upon a main shaft 6, which carries a. control arm 7, projections 8 on the main shaft engaging abutments 9 on the sleeves so as to provide for lost motion between the shaft 6 and the setting drums. Flexible bands 10 are led from these setting drums to corresponding drums 11 loose on the shaft 12 of the printing mechanism. Flexible bands 18 are also led, preferably from the other side of the setting drums, to corresponding drums 14 mounted loosely on the shaft 15 of the totalizer mechanism, such totalizer drums being similarly connected by bands 16 to the printing spindle drums 11 so that these three devices are positively coupled by the bands which are pinned or fixed to the setting drums, tothe totalizer drums, and the printing drums, the effect being that of a continuous band rotatively and positively coupling all three devices. Flexible bands 17 are led from the printing drums and connected to slidable guides 18 for controlling the sale tablet lifters, to which guides the bands 17 permit spring controlled positioning movement. According, therefore, to the angular movement of the setting drums 1, 2, 3, 1, so will. the printing mechanism drums 11, the totalizer drums 1st, and the sale tablet lifter guides 18 be adjusted. The setting drums are rotated on their shaft to the positions for which the keys 19 have been set, by springs 20, and are returned against the action of the springs to their initial position positively by the shaft 6, the projections 8 on which engage the abutments 9 on the drums. The rotation of the setting drum shaft 6 to permit and positively effect the rotation of the setting drums is controlled by the opening and closing of the cash drawer 21. The control arm 7 is fixed on the setting drum shaft 6, and is fitted with a roller 22 which engages a cam surface 23 on the drawer base, in. such manner, that as the drawer is released and opens, the arm 7 is freed to rotate in the direction of the arrow, permitting the setting drums to rotate and their arms 2 to posit-ion themselves against the depressed keys. Each of the setting drums is loosely mounted on the shaft 6, so that they may be capable of relatively different angular movement, according to the positions of the keys depressed in each key bank. The release of the drawer 21 is effected by depressing one of the control keys 25, 26, Figs. 2. and 20., of which several may be fitted, these control keys when operated also actuating a vertically sliding frame 27 operating the sale indicating tablets 28. The frame 27 is vertically guided in any suitable manner, say, by lugs 29, and is engaged by the outer end of a lever 30 pivoted at 31 on, say, one of the side frames 32 of the machine. One end of a spring 33 engages the lever 30, and the other end is an chored to the side frame, as shown in Fig. 2., the aetion'of this spring tending to return the frame to its normal upward position as shown infnll lines, Figs. 1. and 2. The other end of the lever 30 is pivotally connected at 84- to a bar 35, the upper end of which is in turn pivotally connected at 86 to a rocking lever 37 pivoted at 88 to the side frame. The other end of this lever 37 is fitted with a stud 39 slidablc in a curved slot 40 in the side frame, through which slot the stud 39 inwardly projects. The arms 11. of the control keys 25, 26 nor mally rest on the stud 39, so that the depression of either of the control keys 26 de presses the stud 39 and raises the bar 35,

this action pulling down the lever 30 to the position shown in dotted lines, Fig. 2., and permitting the frame to fall to the dotted position indicated in the same figure. As the bar 35 is raised an abutment 12 thereon, Fig. 11., on the interior of the side frame 32,

rides up a slot 413, the abutment clearing the end of a catch 14: pivoted on the drawer 21 and controlled by a spring When the abutment i2 clears the catch, the drawer is opened by the pull of the springs 16, and travels outward on the guide rollers i7. On the outward limit of its travel a projection 4.8 engages behind a lips?) on a spring cacth '50 pivoted at 51, and retains the drawer open until the catch 50 is raised. The outer end of the catch normally bears on a rib pro ecting through a slot 53 and carried on the foot of a bar 5 1 pivoted at 55 to the rocking lever its the control key is depressed the rib 52 passes a notch 56 in the drawer base. so that while the drawer is In order to prevent the movement of the drawer being reversed before completion after once being initiated, a lever pivoted at 57, Fig. 12., is fitted on the drawer, having an eye 58, or the like, slidably engaging a bar 59 fixed on the machine frame or base and having steps 60 at each end. The tail 61 of the pivoted lever is adapted to engage on one or other side of an abutment, such as a roller 62 mounted on a springcontrolled lever 63 pivoted at 64, so that the pivoted lever'58, 61 may take up, and be resiliently held in, one of two inclined positions accordingas to whether the drawer is opening or closing, the lever being retained in the proper inclination for permitting slidable movement on the rod by its tail 61 engaging one or other side of the roller 62 on the spring lever 63. As the drawer reaches its fully opened or fully closed position the eye 58 of the lever is en aged by the end abutments 60 of the bar 59 and the lever canted over to its oppositeinclined position, then permitting movement of the drawer in the reverse direction. The two movements of the lever are indicated in full and dotted lines.

The tablets 28 by which the amount of a sale is exhibited are arranged in banks, Figs. 1., 3., and 17., one bank for each denomination of coin to be registered. Each tablet is preferably vertically guided in a frame comprising an upper slotted plate 35 and a lower bar frame the bars 66 of which engage forked ends 67 on the tablets. The tablets are adapted to be raised to the display position above the plate by lifters 68 slidable on bars 69 beneath the tablets, such bars being carried on the vertically movable frame 27 operated by the control keys 25, 26. These lifters 68 when the frame 27 is down, are positioned beneath the tablets to be raised by the guides 18 slidable on lower fixed rods 70 on the machine framework, such guides 18 being controlled by spring 71 and permitted to move under their spring control to correctly position the tablet lifters 68 by means of the flexible bands 17, which are connected to theguides l8 and to the drums 11 on the printing mechanism spindle. Each lifter 68 is itself spring controlled by means of springs 72 connected to the lifter and its guide. If a series 0 keys be depressed and-a control key operated, the frame 27 is lowered, carrying with it the lifters 68 and bringing them into engagement in front of the forked arms 7 3 of the guides on the lower fixed rods, the guides being in their normal retracted position shown in dotted lines, Fig. 1. Further depression of the control key releases the drawer 21, which in opening retains the frame 27 in its lowered position, also operating the setting drums 1, 2, 3,4, and unwinding certainemounts of the bands 17 from the printing spindle drums 11, and allowing the control springs 71 of the guides 18 to positionthe lifter elements 68 beneath the lower edges'of the requisite tablets. On the terminal opening movement of the drawer the vertical frame is released from the position in which ithas been held during this operation, and rising under the action of the controlling spring 33 raises the tablets to thedisplay. position, the lifters 68 being raised by the bars 69 on the frame. \Vhen the drawer is closed, the tablet lifters 68 are retained behind the raised tablets by a lip 74 which remains caught behind the tabletedge, so that their controlling springs 72 cannot return them to their initial position until one of the control keys isagain depressed to operate the machine, when the frame 27 is again lowered, permitting the tablets to fall and then freeing the lifters 68 from engagement behind their respective tablets, the springs 72 returning the lifters to the normal position shown in dotted lines, Fig. 1., against theguides which had been positively returned by the bands on closing the drawer.

The printing mechanism for the sales record comprises a series of loose drums 11, one for each setting drum and coupled thereto by flexible bands 10, each printing drum 11 being integrally connected, preferably by means of concentric sleeves 75, Figs. 3. and 10., to type faced disks 76. These disks are fixed axially, a recording band 77 being arranged to travel across the disks and below a continuous inking ribbon 78, or the like. A movable platen 79 is arranged to strike the bands 77 against the type disks, the platen being mounted on a vertically movable weighted rod 80, Figs. and 9., operated by a spring controlled lever 81 impinging against a resilient stop 82 and nor- 'mally retained in its depressed position by a trigger mechanism 83 carried on a spring controlled lever 8% pivoted at 85, but re leased on the final opening movement of the drawer, and set on the final closing movement. This is effected in the following manner :-On the drawer is a bracket 86, Fig. 4., an aperture in which slides along a rod 87 fitted with a stop 88 and connected to an arm 89 on a rocker shaft 90. The rocker shaft carries a disk 9.1 fitted with a pin 92, Figs. 2. and 4., adapted to engage the end of the trigger lever 84. The other end of the rod' 87 is connected to a hanging lever 93. As the drawer opens, the bracket 86 engages the stop 88, rocking the shaft 90 and causing the pin 92 to engage the lever 84, the trigger 83 being released and the platen lever 81 raised sharply by the spring 94. As the drawer closes the bracket 86 en; gages the lever 93 and pulls the rod 87 back, rotating the disk 91 in an opposite direction and causing another pin 95 thereon to push down a forked link 96, depressing the lever 81 and enabling the spring 97 to reset the trigger 83. A ratchet wheel 98 on the takeup printing band spindle is also moved step by step'on each closing movement of the drawer, by a pawl lever 99 coupled to the disk 91 on the rocker shaft, so that as the drawer opens it retracts the pawl, causing it to engage behind the next ratchet tooth, the terminal closing movement of the drawer rotating the ratchet 98 and advancing the paper.

The angular movement of the setting drums is limited by the keys 19 when depressed. These are arranged in preferably curved banks corresponding to the denominations of coin, the keys being radially disposed. The keys are slidably mounted in fixed curved plates 100, Figs. 1. and 14., and are held in their normal outward position by springs 101. A curved locking plate 102 is mounted in any suitable manner along the face of the inner fixed plate and controlled by springs or gravity so that it tends to fall and lock the keys when depressed. The locking plate is provided with perforations 103 corresponding to the number of keys, and each key is provided with a cam face 104 and a fiat rib 105. As the key is depressed the cam face lifts the locking plate until the peak of the cam has passed the plate, when the latter falls behind the shoulder of the cam and retains the key depressed againstthe action of its spring. Two keys in one bank controlled by the same locking plate cannot be left down at the same time, the act of pressing down the second key lifting the plate and permitting the first key to fly back through its perforation under the action of the key spring. Engaging with each setting drum arm 24 is a catch 106, Fig. 14., pivoted on a shaft 107 and controlled by a spring 108. In the initial position of the drums a projection on the catch engages the arm as shown, and

' locks the setting drum against movement, if

no key has been depressed. The spring 108 tends to rotate the catches clear of the setting drum arms, but are normally prevented by the lower edge of the locking plate 102. Ifno key is depressed and the drawer opened by a control key 25 or 26, although the setting drum shaftcontrol arm 7 may oscillate, the setting drums remain stationary, the arms being held by the catches. Should a key be depressed, the locking plate is lifted and the catch of that key bank free to be pulled by its spring clear of the corresponding setting drum arm, the flat rib 105 on the key shank holding the locking plate partially raised. The catch 106 and another hook 109 are, however, prevented from being rotated by their springs 108, 111, until the drawer opens permitting a rod 113 to move in the direction of the arrow. Simultaneously with the rotation of each catch 106 clear from its set ting drum arm, the hooked arm 109 pivoted on the catch shaft engages the lower one 110 of two perforations in the raised locking plate by a spring control 111, preventing another key in that bank from being now depressed in substitution, the locking plate being held down. The rotation of the catches 106 and hooks 109 only takes place, however, as the drawer opens. Connected to the shaft 107 is an arm 112 coupled resiliently by a tie rod 113 to the lever 93, Fig.4., a spring 114 being located behind the lever 93 and retained by a nut 115. When the drawer is closed the spring 114 is partially compressed and in this condition holds the catch 106 and the hook 109, by means of projections engaging these elements, against rotation by their springs 108, 111. As the drawer opens and the spring 114 extends and its compression is reduced, the spring 108, 111 free the catch 106 and engage the hook 109. If no key in a bank is depressed the corresponding hooked arm 109 of thatbank engages the upper perforation 116, Fig. 15., and similarly locks the plate against any key being lowered in that bank after the drawer is opened. As the drawer is operated thesetting drum arms 24 rise until arrested by the depressed keys, thus permitting the setting drums to rotate. On closing the drawer the drums are positively brought back by the bands, the terminal movement of closing the drawer resiliently actuating the pull rod 113 which re-sets the catches 106 on the drum arms and frees the hooked arms 109 from the locking plate. The locking plate is also lifted on this terminal movement of the drawer to free the keys by the raising of the bar 117, pivoted on the shaft 107, which engages a projection 118 on the curved locking plate 102, and is in turn lifted by a shouldered pawl 119 pivoted at 120 on a rotary disk 121 and controlled by a spring 122, which disk is coupled by a link 123 to the lever 89 on the rocking shaft and operated by the drawer. The pawl 119 is engaged beneath the bar 117, as shown in dotted lines, on the opening movement of the drawer, the link 123 oscillating the disk 121 tothe dotted position. The final closing movement of the drawer rocks the pawl disk 121, lifting the pawl which raises the locking plate 102 and releases the keys.

The totalizer mechanism is operated from the setting drums 2 positively by means of flexible bands 13, 16, leading to the totalizer from the setting. drums and from the printing spindle drums, which in turn are positively coupled to the setting drums by bands 10. The flexible bands 13 from the setting drums pass on to drums 14 loosely mounted on the totalizer spindle. These drums are fitted with resilient pawls 124, Figs. 7. and 8., adapted to engage with a series of perforations 125 or the like in the numeral disks perforations125 in the stationary numeral disks 126 until thebackward movement of the pawl drums ceases. On closing the drawer the pawl drums rotate in a contrary direction, the pawl gears now positively rotating the numeral disks a corresponding amount to that which the pawl drums have been previously, backwardly rotated. The various amounts are thus'added to the total. The (numeral disks 126 areprovided with ratchet mechanism vl27so that they may only rotate in o'ne direction.

In order "to carry over anincrement of, say, a penny to theshillings disk, or a shilling to the pounds disk, a shaft 128 is fitted near thetotali zer spindle on which shaft are a. series Ioflev'ers 129, 130 coupledinpairs, Figs. 5.6. and 19., the levers of each pair being integrally connected by a sleeve and the 1 pair elements loosely mounted on a shaft 128 so that they may rock thereon. One lever 130Cof each pair is provided with a spring controlledpivoted catch 131 which in its normal position prevents the lever pair from falling by reason of, it engaging a fixed abutment such as a bar 132 onthe machine. A projection 133on each numeral disk 126 is so positioned that it deflects the catch when an increment is to be carried over from one disk to the next of higher value, the lever pair 129, 130 then falling a certain angular distance under'the influence of a spring 134 on to a cam shaft'135. A pawl 136 on the second lever 129 then engages behind and takes upa'nother tooth of the ratchet 127 on the next disk of higher value. In this way, at every complete rotation of a disk of one denomination,'its twin lever fitting is allowed to fall back and its pawl 136 to retreat one tooth on the ratchet of the next higher value disk. The actual forward rotation of the levers 129,130 to totalize the increment carried over .on the train is only, effected after the amount of the particular sale has been registered and totalized. Mounted below the increment levers is a cam shaft 135, the cams 137 on which engage and actuate the levers 129 only when the latter fall. Each twin lever mechanism has a separate cam, the cams of the series being sequentially advanced (see'Fig.13.)so that they come into action serz'atz'm from the lowest coin denomination drum 126 to the highest. The cam shaft 135 is actuated, Fig. 4., from the lower shaft 90, which is rocked by the terminal movements of opening and closing the drawer. A large drum 138 is mounted on the shaft 90 and coupled by a flexible band or Wire 139t0 a small drum on thecam shaft 135. A small angular rotation ofthe shaft 90 thus effects a larger rotation of the cam shaft. On the opening of the drawer the cam shaft is rotated backward and the levers 129 allowed to fall on the flats of the cams, if the catches 131 have been deflected from the bars 132, and on the closing of the drawer the cams are rotated forward and lift those levers 129 which havefallen. This terminal increment movement of the totalizer by the cam shaft is effected only after the ordinary movement of the totalizer imparted by the bands during the primary closing movement of the drawer, by arranging that, the cam surface 23 on the drawer engaging the setting drum shaft control arm shall have completed the return movement of such arm after the drawer has been partially closed, the cam 23 being then in the middle position, Fig. 1., the cam shaft being operated while the roller 22 rides along the top of the cam 23.

A no sale tablet indicating mechanism isprovided which does not require a special key for its actuation. This is fitted in, say, the far-things bank of tablets, Fig. 14. The no sale tablet 140 is so positioned that it is raised by the farthings tabletlifter 68 when the latter is not moved, and the farthings setting drum not rotated. Some provision must be made, however, in order that the no sale tablet will not be lifted when a sale not embodying a farthings quantity is recorded. slot 141, Fig. 15 is,therefore, cut in that part of thefarthings drum arm 24, engaged by the catch 106, which slot, evenwhen such catch mechanism is notreleased, as when a farthings key is not actuated, permits a slight rotation of the farthings setting drum, positioning the farthings tablet lifter in an inoperative position, shown. in dotted lines, Fig, 14., between then'o sale and the first farthings tablet 28, so that should a sale be registered not embodying a farthings quantity, the farthings lifter raises no tablet. In order, however, that such partial movement of the farthings setting drum arm shall not take place when none of the keys of the machine have been depressed, and when consequently the no sale? tablet must be lifted and when the partial movement of the farthings setting drum arm would nevertheless occur, a projection 142 is formed on the farthings drum of the totalizer train, such projection being normally engaged by a trip pawl 143 when none of the keys of any denomination havebeen depressed, the no sale tablet 140 being then displayed by reason of such trip pawl holding the farthings totalizer drum and consequently the farthings setting drum arm against making the partial movement otherwise permitted by the slot 141 in the keys are depressed to register a sale not embodying a farthings quantity, the trip pawl 143 engaging the farthings totalizer drum is released, the upward movement of the locking plate 102 of any of the key banks pushing the pivoted catch l-le which swings a pivoted bar 1&5 which in turn raises the pawl 14-3, freeing it from the projection 14:2, and permitting the drum to be partially rotated the distance allowed by the slot 141 in the farthings setting drum arm, the no sale tablet being then not lifted. By such an arrangement, the machine does not require a special key for actuating the no sale tablet as is usually required, this being a feature of considerable importance.

Where two control keys 25, 26 are fitted, one of the keys, say 26, is connected by a link 146 to a separate printing disk 147, so that when such key is depressed a different type on the disk is brought into the printing position, the record otherwise printing from the normal type on that disk.

Means may be provided for resetting the totalizer train to zero, and counter mechanisms fitted for indicating how many times the drawer has been opened, or otherwise recording the operations of the various devices of the machine.
