1 Claim. (Cl. 235-450) the paper carriage to its extreme right hand position, whereupon said total is printed upon a tally tape. Means may also be provided to eject the upon storage devices and to automatically shiit is a division of application Serial No. 676,230,

filed June 17, 1933, and entitled Listing adding machine.

The invention consists in the novel construction and combination of parts as set forth in the appended claim.

In the embodiment of the invention illustrated herein, a listing calculatoris shown constructed substantially in accordance with the disclosures of U. S. patent application of Loring P. Crosman, Serial No. 607,982, filed April 28, 1932.

It has previously been proposed to automatically initiate a total taking operation upon movement of the carriage of a listing calculator to a predetermined columnar position.

. The invention herein illustrated, however, proposes, upon completion of the total taking cycle of operation, which serves to print the total upon the statement or form sheet, to store said total form sheet during the above-mentioned movement of the carriage, such means forming the subject of the copending application above referred to.

The carriage is thereafter moved automatically to its initial starting position, ready for the insertion of a new form sheet and entry of the first item therein.

The listing register to which the invention is shown as applied is of well known type.

Itwill oted thereto, and the upper arm has pivotal connection with a diiferential stop bar 615 cooperating with a bank of digit keys 215 to limit the movement of the lever 610.

Carriage positioning and operating means A tabulating program bar 1 (Figs. 2, 3

and 8) suitably supported in the frames 3 and 4 of the transversely shiftable carriage 5, is provided with a series of notches 2. Said notches are spaced in accordance with the columnar positions of a given form sheet, and adapted by engagement with a projection 6 of lever 7 to secure the carriage against lateral movement under the influence of a spring drum 8 (Fig. 8).

Lever 7 is fulcrumed at 19 upon a lever 20 iulcrumed at 21 upon the rear casing of the machine and provided with a stud 23 adapted to contact with said casing through a suitable aperture 10, thus limiting the movement of lever 20.

As shown in Fig. 3, a key 11, hereinafter termed a balance key, since the machine is particularly adapted for bank work, is pivotally ed at 12 upon the framing of the machin rearward end of key 11 extends beneath mounte. The the end 13 of lever 7 and, upon depression of said key, will rock the lever 7 to disengage projection 6 from the tabulating program bar 1.

Disengagement of the projection 6 will cause lever 7, under the influence of spring 22, to be moved toward the left, thus rocking the lever 20 to the position indicated by dotted lines, Fig. 2. Also the carriage will now be free to move toward its left, under the influence of drum 8;

spring 1 by means of hooked end 18 of the balance key.

Depression of key 11 will release bail 15 and said bail, under influence of its spring 9, will be rocked beneath the end 18 of key 11, latching said key in its depressed position, holding the projection 16 free of tabulating bar 1; and bringing projection 16 into the path of movement of pin 17.

As the right hand or total column of the form sheet comes opposite the printing position, pin 17 will engage projection 16 and restore bail 15 and key 11 to their normal positions, whereupon projection 6 will be brought under influence of spring 22, into reengagement with the bar 1.

Reengagement of projection 6 with bar 1 will cause levers 7 and 20, under influence of spring drum 8, to be restored to their normal position.

During the excursion of the lever 20 the pin 23 is adapted to operate means for engaging the clutch member 24 (Figs. 4, 5 and 6) to provide for register selection and automatic total taking as follows:

lllotor drive to the register selecting and automatic total taking mechanism As lever 20 is moved to the position indicated by the dotted lines (Fig. 2) stud 23 is carried to the right (as viewed in Fig. 4) of a trip pawl 25, pivotally mounted at 26 upon the upper arm of a latch 27, pivoted at 28 upon a bracket'29.

Upon its return movement, however, stud 23 will contact the surface 30 of trip pawl 25 and rock latch 27 against the tension of its spring 31, to free said latch from engagement with a projection 32 of a spring tensioned plate 33, pivotally mounted at 34 upon bracket 29.

The releasing of latch 27 from plate 33 will cause said plate, under influence of spring 35, to be rocked clockwise about point 34, and arm 36 of said plate will contact a pin 37, fast to one arm 38 of a cross-over bar 39 (Figs. 4 and 6) pivotally mounted upon a short shaft 40.

The cross-over bar 39 is provided with a projection 41 normally in engagement, through a suitable aperture cut in the casing 42 of the clutch 24, with a pawl 43 pivotally secured at 44 to said casing. 4

Contact of arm 36 with pin 37 will raise the cross-over bar 39, and projection 41 will be lifted free of the casing 42 and will disengage from pawl 43, whereupon said pawl, under influence of a spring '45, will be rocked into engagement with a ratchet 46. Ratchet 46 is keyed to a drive shaft 47 having connection, through gears 49, 50, 51, 52 and 53, with the motor 48 as shown in Fig. 5.

The casing 42 of clutch 24 is secured by pins 54 (Fig. 7) to a cam 55, keyed to a shaft 56 having hearings in support plate 57 and having fast to the end thereof a crank arm 58, as shown in Figs. 4 and 8.

During the previously described movement of plate 33 an arm 59 of said plate will engage projection 60 of a lever 61 (Figs. 4, 10 and 12), rocking said lever about its fulcrum 62, to cause an insulated roller 63 fast thereto to close the contact points 64 of a switch 65 interposed in the circuit of the electric motor 48.

Upon contacting of points 64, motor 48, through clutch 24 and the above-described gear train, will drive crank arm 58 in a counter-clockwise direction (as viewed in Fig. 8). The following means are provided to limit the movement of said crank arm to one complete revolution.

Near the end of the revolution of crank arm 58 a projection 201 (Figs. 4, 5 and 7) of cam 55 will contact roller 202 fast to a member 203 loosely mounted upon shaft 40, rocking said member counter-clockwise, as viewed in Fig. 4.

Member 203 has link connection 204 with the plate 33, and as said member 203 is rocked the link 204 will restore plate 33 to its normal latched position and end 36 will release pin 37, to allow projection 41 of arm 39, under influence of spring 205, to rest upon the periphery of the clutch casing 42.

At the extreme end of a revolution of shaft 56 projection 41 will disengage pawl 43 from ratchet 46 and will reengage with clutch casing 42, to secure shaft 56 and crank arm 58 in fullcycle position.

Crank arm 58 has link connection 67 with a rock arm 69, pivotally mounted at upon the right hand framing of the machine. During the above-described rotation of crank arm 58 rock arm 69 is given a reciprocatory movement about point 70.

During this movement a roller 71, secured to said arm, will engage suitable cam members (not shown) and thereby select the desired register in the manner fully set forth in the aforementioned copending application.

Secured to the rock arm 69 is a stud 68 adapted during the last portion of the return movement of rock arm 69 to cause a total printing operation to take place in the following manner:

Extending transversely and secured to the car riage 5 is a bar (Fig. 2) provided with cam shoes 196 and 245 located one toward either end of said bar.

As the carriage is shifted, under influence of spring drum 8; to the extreme left hand position, the cam shoe 196 will be brought to rest upon a roller 197 fast to an arm 198 secured to a square shaft 199 (Fig. 8).

During this movement cam surface 200 will rock roller 197 downwardly and shaft 199 will be rocked counterclockwise, as viewed in Fig. 8.

Secured to the left hand end of shaft 199 is an arm 206 having pin and slot engagement 207 with a lever 208 fulcrumed to the framing of the machine at 209. The forward end of lever 208 has engagement with the projection 210 of a pawl 211, pivotally mounted upon an arm 213, and is adapted to hold said pawl normally out of the path of movement of stud 66.

Counter-clockwise movement of shaft 199,however, will cause arm 206 to impart a clockwise movement to the lever 208 and the forward end of said lever, moving away from projection 210, will allow pawl 211, under influence of its spring 216, to fall until surface 217 rests upon stud 68.

Lever 213 is loosely mounted upon shaft 70 and has link connection 250 with an arm 251 fast to a shaft 252 normally tensioned under influence of spring 253 for clockwise rotation, as viewed in Figs. 8 and 9.

Spring 253 through toggle action of link 250 serves to hold lever 213 normally against the stud 254 fast in the framing of the machine.

During the reciprocatory movement, previously described, of rock arm 69, however, the surface 255 of pawl 211 will fall into the path of return movement of the stud 68. Lever 213 during the last portion of the return movement of said stud will thus be rocked upwardly beyond toggle center position whereupon spring 253 will act to complete the movement, imparting clockwise rotation to shaft 252 until stopped by the contact of surface 256 of lever 213 with stud 68.

Pivotally mounted at 257 (Figs. 3, 9. and 10) upon a crank arm 258, secured to the right hand end of shaft 252, is a finger 259, provided with a projection 260 normally overlying the forward end of the total key 2'78. As shaft 252 is caused to rotate finger 259 is carried downwardly, rocking the total key about its fulcrum 261 until latched in depressed position by engagement of I the hook end 262 of said key with suitable spring tensioned latching means 263.

Near the end of the rotation of shaft 252 (counterclockwise as viewed in Fig. 10) the surface 264 of finger 259 will contact the hub of crank arm 258 and cause said finger to be rocked free of the total key 278.

As set forth in the aforementioned application, Serial No. 607,982, a total is taken by releasing the differential stop bars 615 and allowing their segment racks to rotate the accumulators subtractively until suitable pins on the accumulator wheels contact with zero stop members. This will set the total (the amount subtracted from the accumulator wheels) in the type bars and the hammers will themgbs tripped to print the total.

Depression of the total key 278 is adapted to lift the column latches 214 (Fig. 1) free of the stop bars 615 in the following manner:

The rearward end of key 278, upon depression of said key will engage stud 279 to impart clockwise movement to a bail 280. Bail 280 is provided with a cross-over member 281 overlying the forward end of the column latches 214 and will therefore, when so moved, rock said latches free of the stop bars 615.

The levers 610 are then successively released from the restoring frame in the following manner:

A shaft 282, having its right hand end formed as a crank arm (Fig. 10), projects over the rearward end of the total key, and is caused to be rocked counter-clockwise upon depression of said key.

Secured to shaft 282 is an arm 283 adapted to impart clockwise movement to a latch 620, upon the above-described movement of said shaft, by engagement with a pin 284 secured to control arm 621, pivotally mounted upon said latch.

Latch 620 normally engages a lug 627 on total segment 618, preventing movement of said segment under influence of the total spring 681. Upon tripping of the latch, however, segment 618 will be rocked upwardly about its fulcrum point 628 and will impart counter-clockwise rotation, through gear 629, to a shaft 607 (Fig. 1). Shaft 607 extends transversely of the machine and is provided with a series of spirally arranged pins adapted during rotation of said shaft to trip, successively from right to left, a series of latching dogs 617, mounted upon the restoring frame and engaging pins of the levers 610.

Tripping of dogs 617 will also cause a stop When this zeroizing operation has progressed to the left hand side of the machine a stud 630 in the total segment 618 will contact with a projection 129 of a rod 130 connected at its other end to a trigger 131. Trigger 131 will thus be moved to release a latch 150, allowing said latch under influence of its spring 151 to be rocked .out of engagement with the projection 152 of a pawl 153, pivotally mounted upon the crank arm 105, causing said pawl under influence of its spring 156 to be rocked into engagement with a notched disk 168, fast to the hub 169 of gear 50 (Fig. 5), having drive connections with motor 48 as previously described.

During the above-described movement of lever the surface 170 of said lever will contact a stud 171 fast to the lever 61, and rock said lever downwardly, to cause the insulated roller 63 fast thereto to contact the points 64 of the motor switch 65 and initiate an operating cycle of the machine. The machine being put in operation the hammers will be tripped to print the total and the levers 610 and total key 278 returned to normal, as fully described in the aforementioned application.

The following means are provided, however, to hold the column latches 214 free of stop bars 615 when the other parts have been returned to normal position:

A lever 173 (Fig. 8), fulcrumed at 174 upon the left hand framing of the machine, is provided at its upper portion with a projection 175 engaging a bell lever 176, fulcrumed at 177 and having one arm formed as a hook 178. The lower portion of lever 173 is held against a pin 179 of arm 213 by means of a spring 180.

As lever 213 rises, pin 179 will contact the surface 181 of lever 173 rocking said lever clockwise about point 174 and imparting counterclockwise movement to bell lever 176.

- This will cause engagement of the hook end 178 of lever 176 with a pin 182 secured to the left hand end of the bail 280, locking said bail in the position (indicated by dotted lines) assumed upon depression of the total key 278. Thus, the column latches 214 will be held free of the stop bars 615, for the purpose hereinafter described.

Means for storing a total As shown in Fig. 3 a link 183 is eccentrically mounted upon shaft 252. The rearward end of said link is pivotally connected at 184 to a pawl 185 pivoted at 186 upon lever 187. Lever 187 is held normally in the position shown in Fig. 3 by a link connection 188 with arm 189 fast to shaft 190.

During the rotation of shaft 252 previously described link 183 will rock pawl 185 counter-clockwise about point 186. This will cause projection 191 of said pawl to rock a lever 192, fulcrumed at 193 to bail 194, into the path of movement of a pin 144 secured to a cam arm 320 fast to shaft 301.

During an operating cycle, crank arm 105, having link connection 108 with a cam 316, fast to shaft 301, will impart reciprocatory movement to said shaft and the cam arm 320.

Near the end of the forward stroke of the operating parts pin 144 will engage lever 192 and rock bail 194 counter-clockwise as viewed in Fig. 3, causing a rearwardly extending arm 145 (Figs. 3 and 11) of said bail to contact a projection 146 and rock latching pawl 158, mounted upon plate 159, out of engagement with latch arm 157. Plate 159 being thus released will be drawn rearwardly by spring pressed member (Fig. 10) and'a lug 161 of plate 159 will engage lug 162 of the link 130 connected to trigger 131, holding this trigger out of engagement with the latch 150.

During the successive release of the levers 610, previously described, a set of stops 143 (Figs. 1 and 10) yieldably engaging stop bars 615 will be set according to the amount of movement allowed in rotating the accumulators back to their zero position. 7

The stop segments 143 are then looked in this position in the following manner:

The plate 159 is provided with a pivoted extension 163 (Figs. 10 and 11) which, in the rearward movement of the plate is held under tension against the pin 164, mounted on one end of an intermediately fulcrumed lever 165. The forward arm of lever 165 operates a locking bail 166 (Figs. 1 and 10) engaging serrations of the stops 143, the lever being normally operated by a double faced cam 167 secured to arm 316 of operating shaft 301.

As arm 316 moves forward cam 167 will be carried idly to a point in front of a roller 172 fast to lever 165, while in the rearward movement of arm 316 cam 167 will rock the lever 165 to bring bail 166 into engagement with the stops 143.

As the rear end of lever 165 is lifted by cam 167, in the return movement of the parts, pin 164 will be lifted free of extension 163, whereupon said extension will immediately move under the pin, holding locking bail 166 in engaged position.

The stop bars 615 are then returned to their normal position, together with their levers 610, as previously stated.

Near the end of the total printing cycle of operation a projection 115 of crank arm 105 will latch 150. latch arm 275 will'now fall, under influence of its spring 277, and rest upon the projection 266 of plate 33, locking the latch 150 in position of engagement with pawl 153.-

Returning the carriage to its extreme right hand position Secured tothesquareshaft 199isanarm218 (Figs. 2 and 3) adapted during the previously described movement of said shaft to tension a spring 219securedtooneendofalink220. The opposite end of link 220 is pivotally connected at 221 to a latch 222, pivotally mounted upon a plate 223, pivotally secured at 62 to the bracket 29.

As shown in Fig. 3, latch 222 is held by tension of spring 219 against a roller 224, fast to a lever 327 secured to shaft 302 and having link connection 321 with the cam 316. During the forward movement of cam 316 lever 327 is also rocked forwardly, whereupon hook end 225 of latch 222 will be moved into the path of return movement of roller 224.

Upon completion of the total printing cycle of the machine roller 224, in returning to its normal position, will engage the hook end 225 of latch 222 and cause plate 223 to be rocked up:

wardly about point 62, to engage clutch means for returning the carriage, in the following manner:

Plate 223 has connection through a flexible link 226 with a clutch operating member 227, provided with projections 226 having engagement with suitable slotted indentures of a pair of disks 229 (Figs. 3, 5, 13 and 14) loosely mounted upon a sleeve 230 secured to the shaft 231 of the carriage return clutch mechanism shown in Pig. 5.

A bracket 232 (Figs. 3 and 13), suitably secured to the clutch casing. acts as a fulcrum for the clutch operating member 227 and as plate 223 is rocked upwardly, flexible coupling 226 will be tensioned, to impart a twisting movement to said operating member, and projections 228 will tend to impart lateral movement to the disks 229.

Lateral movement of the disks 229 is adapted, through suitable ball thrust bearings 233 (Fig. 5), to cause frictional engagement of plate 234, keyed to the clutch shaft 231, with a drum 235, loosely mounted upon a bearing 236 supported by the bracket 237.

During the above-described operation of plate 223 an insulated roller 238 (Fig. 12), mounted thereon, will contact the points 64 of switch 65 to close an electrical circuit to motor 48, whereupon said motor, through gears 53, 52, 51, 50, 49, shaft 47, gears 239 and 240, shaft 231 and plate 234, will rotate drum 235, whereupon tape 241, suitably secured to said drum and to the carriage will be wound upon the drum to cause return movement of said carriage.

,As the carriage is brought to its extreme right hand position the surface 243 of a cam shoe 245 (Fig. 2) will rock the roller 197 upwardly to impart counter-clockwise movement (Fig. 3) to shaft 199.

Counter-clockwise movement of shaft 199 will cause a pin 244 fast to lever 218 to move link 220 downwardly and disengage hook end 225 from roller 224 to release plate 223, and clutch operating arm 227 will release plate 234 from drum 235.

Automatically re-printina the total upon a tally im As the carriage is moved into its extreme right hand position, bringing a paper tally tape 100 opposite the type bars, pin 23 (Figs. 2 and 4) will again trip the latch 27 to cause rotation of shaft 56 and a second reciprocatory movement to rock arm 69, in the manner previously described. Also the projection 266 of plate 33 in moving upward holds latch 150 in engagement with pawl 153, while restoring latch arm 275 upon the projection 207 of latch 15o.

During this second operation of rock arm 69, pin 68 will restore arm 213 and consequently shaft 252, flnger 259, link 183, pawl 185 and lever 192 to their normal positions. Also lever 173 will move under influence of spring away from bell lever 176. A sufllcient undercut to the hook end 178 of said bell lever will, however, hold same in engagement with the pin 182 column latches 214 thus remaining free of the bars 615.

At the completion of the rotation of shaft 56 plate 33 (Fig. 4) will again be restored to normal,

in the manner previously described,'and the projection 266 of said plate will release projection 267 of latch 150 to initiate a second operating cycle of the machine.

During this operating cycle the stop bars 615 will move forwardly to feel out the stops 143 and bring the corresponding value type into printing position; the hammers are then tripped, reprinting the total upon the tally tape 100.

Near the completion of the total reprint operating cycle, lever 327 (Fig. 10) by engagement withroller 295 of pawl 296 will rock plate 297 and, through latch 298, the bail 280. Thus pin 182 (Fig. 8) will be moved free of hook 178 and bell lever 176 will be restored to normal under influence of its spring 299, whereupon column latches 214 will re-engage with stop bars 615.

During the above cycle a pin 148 in cam 316 will engage the part 149 of extension 163 and restore plate 159 to normal position, releasing the lever 165, and bail 166 under influence of spring 147 will be released from stops 143. Also the projection 161 of plate 159 will be moved free of lug 162 and as projection again wipes projection 116, to disengage the drive means, trigger 131 (under influence of suitable spring means, not shown), will re-engage and hold latch in the normal position illustrated in Fig. 10.

Upon completion of the cycle the carriage 5 is released and shifted to the first columnar position of the form sheet, by the well known tabulating means, and all parts are now in normal position.

The tally tape 100 is preferably supported in a basket 101 adjustable laterally along the support rods 102 and 103 of the carriage 5, (Fig. 2).

I claim:

In a listing adding machine having a transversely shiftable platen carriage, register wheels and type carriers; the combination with total printing means including elements for rotating the register wheels to zero and for setting the type carriers in accordance with the movement of said wheels to zero, and motor driven printing elements including a clutch; of devices difierentially settable in accordance with the type setting, means for holding said devices as set after release of the clutch, means automatically operable after the operation of said printing elements to shift the carriage transversely, and means operable upon movement of said carriage into its shifted position and cooperating with the total printing means to reengage the clutch, automatically adjust the type carriers in accordance with the setting of said differentially set devices and to effect a second operation of the printing elements.
