This invention relates to cash registers, and particularly to improvements in the type of machine shown in applicants Letters Patent of the United States, No. 1,555,534

granted September 29, 1925.

One of the objects of this invention is to provide novel means adapted to be operated as a preliminary to an operation of the machine, to place the machine in condition to rere ceive the entry of items and print the same, or to print a sub-total or a grand total; and to provide an interlocking mechanism to prevent movement of the novel means out of its position of adjustment during either a subtotal or total printing operation.

Another object of this invention is to provide counting devices to count the number of times totals and sub-totals are printed.

It is also an object to provide a record strip wide enough to receive, in addition to the printed items and totals, written memoranda, such record strip being mounted upon a movable carrier which brings the last printed item into view.

Another object is to provide interlocking mechanism which prevents an operation of the total printing mechanism and the count ing devices during an operation of the item entering me ans.

Another object is to provide locking means controlling the reading and resetting of the totalizer.

Still another object is to provide means for oscillating the record strip carrier by either the item entering means or the total printing means and independent of each other.

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form or embodiment of which is hereinafter described with reference to the drawings F which accompany and form part of this specification.

The machine to which the present invention is applied, includes the usual amount keys, means for indicating the amount set up by the keys, means for entering said amount in a totalizer and for printing the same, and means for printing the total of the amounts entered. To such a machine mechanism is provided for counting the number of times the totalizer is read and also reset, for controlling read and reset operations of the totalizer, and for moving the paper for displaying the last printed record.

Referring to Figs. 1 and 2, the amount keys '25, arranged in denominational groups as usual, are pivoted on a transverse rod 26 car ried by the side frames of the machine, and at their rear ends are notched to cooperate witha lip on a key coupler 27 for purposes well known in the art.

The rear ends of the re s are extended to cooperate with indicators 28, and also with pivoted key stops 29 which prevent a simultaneous depression of a plurality of keys in a single denominational group.

Differentially notched arms 30 connected to the rear ends of the keys, are provided with notches 31 for engagi rods 32 carried by registering frames 33 sipported on a shaft 3 1. There is a registering frame for each denominational group of lreys 25, and each of the frames nas operatively connected to it aregis ering segment These segments are grouped as shown in Fig. 1 with the right hand one directly attached to the frame and the othe connected with their respec tive frames by the heft 3i and pinions 86 and 3? securef to shafts 3S and respectively. The notohe; in the 80 are locate t'ansmit amounts of movement to the actuators n'oportionate to the number of units represented by the keys to which the acne are connected.

The registerin segments or total-zer actuators 35 are normally in mesh with gears 10 which are operativeiy connected with the item type wheels 41 (Figs 1 and 6) by a tube line 4-2 to set up the amounts represented by the keys depressed. Referring to Figs. '7, 8 and 9, securol to the right hand end of the tube line -12 are 43 which mesh with pinions 14 mounted on rods 15 carried by plates 49, each provided with a hub supported by the right hand side frame of the machine and a printer frame 66. These pinions 1 1 are sleeved to companion pinions 16 which mesh with 17 secured to the left hand end of atube line 18 to the right hand end of which the type wheels 4:1 are attached.

The autographic record strip 67 sup ported on an oscillatin frame 71 (Figs. 1 and 6) pivoted on a st id 7 2 projecting from the side frame of the machine. This osci lating frame is moved first clockwise to placthe next impression receiving portion of th paper in alinemcnt with the type wheels to receive an impression "dierefron1 and then counterclocl;wise to place the last received impression in position to be read through the opening in the casing 73 In item printing operations the oscillating frame 71 is operted by the key coupler which is pro ider; on ht hand end. with a trunnion 7-1 (Fig. through the printer frame.

PA g:

an arm 83 and cause the arm in unison with the arm 80. This arm is seemed to a sleeve Set to which is secured the paper supporting frame 71. The pin 82 is carried. by a pitnian S5 actuated by the total printing mecl n to disconnect the uaper supporting frame operating mechanism from the item ei'itering mechanism during a total printing operation which will hereinafter be described.

The paper 67 (Fig. 0) is fed from a supply roll over the top of the supporting .'frame 71 and on to a receiving roller 101. When an item is printed the paper is fed forwardly by a pawl 102 engaging a ratchet wheel 103 as the siu'iporting frme 71 moves clocltw'se. The usual spring actuated pawl 10% prevents a retrograde movement of the receiving;

roller. The pawl 102 is pivotally mounted on a lever 105 which is provided with a slot engaging a stud 106 support-ed in the prime 1 frame 66. The upper end of the le' 105 carries a pin 10'? which ent bracket 108. 'llhe paper car be fed independently of an operation of the machine by moving the lever 105 in a counter-clockwiso dir action with the pin 107 ti aveling in the slot 196 in the bracket 108. By this feeding oper ation the printed total is brought into reading position. A spring; tension plate 109 bearin against the supply roll 100 maintains the proper tension on the paper to keep it taut.

An inking ribbon passes between the type carriers and the paper, over guide pins and partly around a feed roller 116'which is rotated by the usual pawl and ratchet device. The ribbon feed pawl 117 is carried on an oscillating lever 118, connected by a link 119 to the paper supporting frame 71. The ribbon has cooperating therewith the usual tension roller 120 which is well known in the art.

The amounts represented by the keys depressed are also entered in a totalizer mounted in a frame 121 (Figs. 2 and 3) pivotally supported on pins 122 mounted in brackets projecting rearwardly from a front cross bar 123 secured to the side frames.

- The totalizer elements (Figs. 2 and 3) include pinions 124 rigid with gear wheels 125 and ratchets 126 supported on a turn-to-Zero shaft 127. The shaft is provided with a groove to cooperate with spring-pressed pawls on the totalizer elements to turn the totalizer to zero in the usual manner.

The totalizer pinions 124 are normally held disengaged from the actuators 35. by a cam 128 on the cam shaft 59, which cooperates with rollers 129 on a lever 130 mounted on a pivot pin 131 on the totalizer frame. The end of the lever 130 contacts a'pin 132 on the totalizer frame 121 to rock said frame to engage the pinions 124 with the actuators 35. One of the pins 122 projects through the lever 130 and acts as a means for holding said lever immovable relative to the frame 121, so that said frame may be rocked by the lever 130 to disengage the pinions 124 from the actuators 35. When a key is depressed the cam is rotated clockwise and the totalizer pinions 124 are moved into mesh with the actuators and out of mesh therefrom in a manner well known in the art, and disclosed in United States Letters Patent, Nos. 718,565 and 773,060, granted January 13, 1906, and October 25, 1904, respectively, to Joseph P. Cleal.

For the purpose of effecting transfers each totalizer wheel is provided with a transfer disk having a trip nose 136 adapted to engage a nose on a transfer trip pawl 137 to move the same out of supporting relation with respect to a transfer pawl 138 which may then move into engagement with the ratchet 126. This pawl is pivotally supported on a transfer lever 139 which is rocked usual by cams (not shown) on the cam shaft 59, during each item entering operation of the machine.

The amount accumulated in the totalizer is ascertained by a printing operation. For this purpose, mechanism is provided for set ting up total type wheels 141 (Fig. 6) to print the amount in the totalizer which has stepped disks 142 (Figs. 2 and 3) rigid with gear wheels 143 mounted on a rod in the totalizer frame 121 and meshing with the gears 125 rigid with the totalizer pinions 124.

The total type wheels 14]. (Fig. 6) are located to the right of the printer frame 66 and are suitably supported by said frame and a supplemental frame 144. These wheels are connected by a tube line 145 with gears 146 (Fig. 10) in mesh with segments 147 rigidly connected with segment 148 in mesh with segments 149 connected by a tube line 150 (Figs. 1 and 10) with feeler arms 151 adapted to be moved into engagement with the steps on the disks 142 of the totalizer. The tube line is supported by a rod 152 supported in t1 e orinter frame and in a bracket 153 mounted on the front cross bar 123. The steps on the stepped disks 142 are so located that the type wheels will be set in accoreance with the amount in the totalizer when the feeler arms 151 are moved into contact with said. disks.

Also integral with the segments148 are other segments 154 (Fig. 10) which mesh with segmental gear levers 155 provided with hooks 156 supporting the upper ends of tension springs 157 which are also attached to a lever 153. The springs are normally restrained against moving the arms 151 and total. type wheels by a lever 159 connected by a ii .1; 160 to said lever 158 and having a bar 1 lever 158 is rocked first clockwise and then counter-clockwise by cams 161 secured on a driving shaft 162 driven by a gear 163 (Fig. 14) in mesh with a gear 164 driven by a crank 165 6) or any suitable means. As the lever 156 is moved clockwise the bar 166 is removed from the lovers 155 and the springs 157 are permitted to function to set up the total type wheels in accordance with the amount in the totalizer in the manner described in the previously mentioned Von Pein patent, No. 1,555,534.

The driving shaft 162 makes one rotation for each total printing operation, being stopped at the end of the rotation by a notched block 170, (Fig. 14) secured to the gear 163, engaging an arm 171 freely mounted on a pin 172 supported by the printer frame 66. Before the shaft 162 can move cou'nter-clock wise it must be given slight clockwise movement by a reverse movement of the operating crank which permits the arm 171 to be moved counter-clockwise by a spring 173 assisted by a plate 174 engaging an arm 175. Projecting laterally from the arm 175 and through an opening in the arm 171 is a pin 176 to which one end of the spring 173 is attached. the shaft rotates counter-clockwise the plate 174 is brought into engagement with the lower side of the arm 175 thereby moving the arm clockwise and through the pin 176 cooperating with the upper side of the opening in the arm 171 to cause the arm to move clockwise and engage the notched block to stop the shaft 162 at the end of a complete rotation thereof.

Impressions from the total type wheels are made upon the autographic strip 67 re ferred to, by an arm 1'79 (Fig. 0) which carries a platen to print the total shown at the top of the strip in Fig. 1. The arm 179 is pivoted on a stud 180 supported in the print er frame 66 and carries a roller at lower end cooperating with a cam 182 formed in the side of the gear 163.

The paper supporting frame 71 is oscillated during a total printing operation by a cam 1553 (Figs. 11 and 12) secured to the driving shaft 162. Cooperating with the cam is a roller 18% carried on a pitman 185 one end of which is connected by a stud to an arm 18% secured to the paper supporting frame. The cam is provided with a slot 187 into which the roll 184; moves when the paper supporting frame is oscillated by the item entering means previously described.

The pin 82 (Fig. 6) which couples the arm with the arm 83 to oscillate the paper supporting frame during an item entering operation as previously described, is moved out of the notch in the arm during the total printing operation, by a cam 199 (Figs. Sand 11) secured to the driving shaft 162 and cooperating with a roller carried on the pitman 85.

During a total printing operation the ratchet and pawl paper feeding mechanism 102103 is disabled by a earn 192 (Figs. 10 and 11) secured to the driving shaft 162 and and cooperating with a roller carried on a pitman 193 the forward end of which has a slot 194 engaging a pin 195 mounted in the lower end of a downwardly extending arm of the pawl 102 (Fig. 6). The pawl is moved counter-clockwise on its pivot by the arm 192 and pitman 198 so as not to engage the ratchet 108 when the frame '71 oscillates.

The printed total is moved into View after a total printing operation by manually feeding the paper by moving the pin 107 (Figs. 1 and 6) downwardly in the slot 196 formed in the bracket 108. This causes the pawl 102 to engage a tooth in the ratchet 103 and to move the paper receiving roller 101 counter clockwise. This operation is repeated until the printed total is visible through the openin in the casing 73.

llileans are provided for printing reading or sub totals and reset or final totals. In printing reading totals the amount accumulated upon the totalizer is printed upon the autographic strip without resetting the totalizer to zero, while in printing reset totals the totalizer is simultaneously reset to zero.

The total printing is under the control of a slide 197 (Figs. 1 and 6) which has a normal position for entering items on the totalizer, a rear position for reading the total, and a forward position for resetting the tctalizer. A handle 198 projecting upwardly from the slide 197 and through a slot in a cover 199 constitutes a manipulative means for positioning the slide. The manipulation of this slide is under the control of locks 200 and 201 supported in a casing 190 (Fig. 10) carried by a bracket 191 secured to the printer frame 66.

ecured to the handle 198 is a bracket 202 (Figs. 1 and 6) which normally projects be tween the lock bolts 208 and 20 1 of the locks 200 and 201 respectively when both lock bolts are in their locked positions, as shown in F ig. 1, thus locking the slide 197 in the normal item entering position, thus locking the total printing mechanism, as will hereinafter be described. Unlocking the lock 200 withdraws the lock bolt 203 permitting the moving of the slide 197 to the read position which permits an operation of the total printing mechanism to print on the autographic strip a total of the items accumulated in the totalizer without resetting the totalizer to zero. By unlocking the'lock 201 the slide 197 may be moved forwardly to the reset position so that a total may be printed and in addition the totalizer automatically reset at Zero.

The slide 197 (Figs. 1 and 6) is provided with a downwardly extending arm 205 having a bifurcated end engaging a pin 206 carried by a type carrier similar to the type carrier 1&1. This type carrier contains two type characters to designate a read total and a reset total. The total shown in Fig. 1 is a reset total designated by the letter Z. Any other character may be used to distinguish the different totals.

The slide 197 is supported by pins 210 and 211 projecting laterally from the printer frame 66. Secured to the right hand end of the slide is a curved plate 212, which, when the slide is in normal position, is underneath a flat sided pin 213 (Figs. 5 and 6) projecting from the link 160, to prevent the operation of the total printing mechanism.

Moving the slide to the right or into the read position will move the plate 212 away from the pin 213 and permit an operation of the total printing mechanism, and at the same time will disengage a latch 21 1 (Figs. 5 and 6) from a segment lever 215. This latch is pivoted to the link 160 by a screw stud and has a laterally projecting pin 216 engaging a curved slot 21.7 formed in the slide 197. A notch 218 in the latch 21% normally engages a pin 219 carried by the segment lever 215.

The plate 212 is so shaped that as the link 160 moves downwardly during the reading operation, the pin 213 travels along the front edge 22 1 of the plate, thus locking the slide 197 in the read position until the operation has been completed.

The segment lever 215 meshes with a partial gear 220 secured to a shaft 221 (Fig. 6). This gear carries a pin 222 which enters a notch 223 in the slide 197 to retain the gear and segment lever in their normal positions when the'latch 214 is disengaged from the pin 219.

Moving the slide to the left or into the reset position, withdraws the notch 223 from the pin 222 but maintains engagement of latch 214 with the pin 219 in the segment lever 215. T is movement of the slide 197 to the left also moves the plate 212 to the left and away from the pin 213 permitting operation of the total printing mechanism together with the operation of the totalizer resetting mechanism.

As thelink 160 moves downwardly during the reset operation, the pin 213 travels along the rear edge 225 of the plate 212, thus locking the slide 197 in the reset position until the operation has been completed.

Resetting of the totaliz er to zero is effected by actuation of the segment lever 215 which meshes with the partial gear 220 secured to the shaft 221 which freely supports the segmerits 147, 148 and 154 (Fig. 10). Secured to theshaft 221 on the left side of the printer frame is a segment 226 which meshes with a gear 227 carrying a spring-pressed pawl 228 cooperating with a ratchet 229 integral with a gear 230 in mesh with a gear 231. The gear 231 is secured to a shaft 232 connected by a universal short shaft coupling 233 (Fig. 1) with the turn-to-zero shaft 127 (Fig. '3) of the totalizer. The shaft 127 carries a cam 234 (Fig. 1) which cooperates with an arm 235 connected to a shaft carry ing arms 236 (Fig. 3) to raise the transfer pawls 138 during turn-to-zero operations. By means of this mechanism the totalizer is turned to zero during the latter part of the total reset operation.

For the purpose of counting the number of times a read or a reset operation is made,

counting devices are provided to be actuated during these operations. These counting devices are the regular step by step counters and are supported by the bracket 191 (Flgs. 6 and 10) and are inoperable when the slide 197 is in its normal position.

Counter 237 is actuated during a read operation by a lever 238 (Figs. 6 and 10) pivoted on a stud 239 mounted in the slide 197, and having a slot 240 engaging apin 241 projecting from an oscillating arm 242 secured to the counter actuating shaft. This lever is normally held in contact with a pin 243 pro- .jecting laterally from thebracket 191 (Figs. 6 and 10) by a spring 244. The lever 233 is moved clockwise during the total printing operationby a pin 245, carried by the lever 159, engaging a foot 246 on the lever 233, thus operatingthe arm 242 (Fig. 6) to add 1 on the read counter.

-The reset counter 247 is actuated by a lever248 (Fig. 10) pivoted on the stud 239 and normally held in contact with the pin 243 by a spring 249. A slot 250 in the lever 248 engages a pin 251 projecting from an oscillating arm 252 (Fig. 6) secured to the counter isters with provision for memoranda in connection with the item printing. Read and reset operations of the totalizer being controlled by locks, are ordinarily not available to the operator, the keys for the locks being in the possession of the proprietor or some authorized person.
