Upon operin part. ation of the machine, mechanism becomes effective to return the registration indicator from non-registered to registered position, whereupon the latch mechanism becomes effective to retain said indicator in registered position.

Near the end of a machine operation, mechanism becomes effective to release the latch mechanism which retains the cash drawer in closed position, thus freeing said cash drawer to the action of a spring, which immediately opens said cash drawer.

Conveniently located on the right-hand side of the machine cabinet is a cashiers lock, which controls the operation of the machine, the reading of the totalizer and the removal of the machine cabinet. The possessor of the key to the cashiers lock may position the lock to any one of its: three positions. When the lock is in its #1 or normal position, the machine cabinet is locked against removal, a shielding mechanism obstructs the view of the totalizer wheels and the machine operating mechanism is unlocked. When the cashiers lock is in its #2position, the cabinet is unlocked for removal, the totalizer shield is moved to ineffective position, so that the wheels of the totalizer may be viewed, and the machine operating mechanism is unlocked. Moving the cashiers lock to #3 position locks the cabinet against removal, moves the shield to effective position to obstruct view of the totalizer wheels and locks the operating mechanism.

The machine embodying the instant invention has two lines of type wheels, one of which prints upon an issuing receipt and the other upon a detail strip, which is retained in the machine and may be removed at the end of a certain business period. Each of the type wheel lines has an amount type wheel for each of the amount levers, which wheels are connected to and positioned by said levers as explained earlier herein.

In addition to the amount type wheels, the receipt type wheel line has a plurality of consecutive number type wheels, which are automatically advanced one step each machine operation. The consecutive number wheels and the wheels of the totalizer may be reset to zero position at will by any authorized person having possession of the reset wrench for these wheels.

A settable lever, similar to the amount levers, located on the left-hand side of the keyboard, positions a clerks indicator and two clerks type wheels, one on each of the type wheel lines, to indicate and record a letter identifying the clerk making the transaction. A plurality of manually'positionable date wheels are provided for printing the date upon the issuing receipt.

An electro printing device is provided for printing various data of a descriptive or advertising nature upon the face of the issuing receipt. The type wheels are inked by an endless ribbon supported by a removable frame, which may be easily and quickly removed from the machine when it is desired to change or adjust the inking ribbon. The electro printing and the receipt feeding mechanism may be disabled when desired by means of a manipulative device located on the left-hand side of the machine.

The mechanism pertinent to the present invention will now be described in detail.

Dnmmnn Dnscmr'rion Framework The mechanism of the present machine is supported by a right frame 20 (Fig. 6) and a left frame 2 1, connected by various cross-rods, shafts and frames, and by a base plate 22, secured to the top of a drawer cabinet 23. The mechanism of the machine is enclosed by a suitable cabinet 24 secured to the machine framework by means of screws (not shown) and by means of a rod 25 (Fig. 1), in cooperation with notches in two lugs 26 attached to the cabinet 24.

A main shaft 21 (Figs. 1, 3 and 6) journaled in the frames 28 and 2|, is operated by means of a crank 28, loose on a stud in the frame 20, and geared to said shaft by means of an idler gear l8 loose on a stud in the frame 28 and a co-acting gear 59 fast on the right end of the shaft 21. Two clockwise revolutions of the crank 28 drive the shaft 21 one revolution in a clockwise direction to effect an operation of the machine. A stop device (not shown) obstructs movement of said main shaft 2'! after it has completed one revolution of movement and before the shaft can again be rotated it is necessary to back up the crank 28 and the shaft 21 a slight distance to release the stop mechanism. As this type of stop mechanism is well known in the art it is thought unnecessary to illustrate and further describe such mechanism.

Amount differential mechanism Loose on the shaft 2i (Figs. 1, 6, 8 and 9) is an amount lever 29, for each denominational order, an upward extension of which terminates in a fingerpiece 39, which protrudes through a corresponding arcuate opening in the cabinet 2d. Numbers from zero to nine, corresponding to the different positions of the levers 29, are engraved upon the cabinet 25, opposite the openings for the finger pieces 38. A bent-over portion of the finger piece 39 (Fig. 9) has an aperture therein through which the numbers are visible when the levers 29 are moved from one position to another position corresponding to this particular number.

Each of the levers 29 has a plurality of V- shaped notches 3i cut in a segmental portion thereof. Said notches correspond to the different positions of the levers and are adapted to cooperate with their respective rollers 32, each of which is mounted upon a corresponding lever 33, loose on ashaft 34 supported by the frames 20 and 2|. A spring 35 urges the levers 33 clockwise to maintain the rollers 32 in engagement with the notches 3i thereby providing a means for locating and retaining the amount levers 29 in set positions. Each of the levers 29 is connected by a link 36 to a corresponding gear sector 31, loose on the rod 34 and having teeth which mesh with the teeth of a corresponding gear 38 integral with a front roller type indicator 39 supported by a shaft 40 journaled in the frames 29 and 2i. The lowest order front indicator 3!) (Figs. 1 and 6) is secured on the shaft 4i), as also is the lowest order rear indicator ii, while the higher order front indicators areconnected by nested tubes to their corresponding higher order rear indicators, said nested tubes being rotatably supported upon the shaft 30.

Each of the settable levers 29 has a segmental portion-of gear teeth 42, which mesh with a corresponding drive gear 43. The lowest order drive gear 43 (Figs. 1 and 6) is secured on a shaft 44, journaled in the frames 20 and 2i, as also is a corresponding type wheel drive gear 46, while the higher order drive gears 43 are connected by corresponding nested tubes 45, supported by the shaft 44, to their corresponding type wheel drive gears 46. The type wheel drive gears 36 mesh with corresponding amount type wheels 41 of an upper or receipt type wheel line and with corresponding amount type wheels 48 of a lower or detail strip type wheel line. The receipt type wheels l? rotatably mounted upon a stud 49 secured in the frame 2! and the detail type wheels 38 are rotatably mounted on a stud 50 also secured in the frame 2i.

It is therefore obvious from the foregoing description that positioning the amount lever 29 also positions the corresponchng front and back indicators 3?) and ll and the corresponding type wheels ii and is in proportion to the position of said levers.

A olerks lever 5i (Fig. 6), similar in every respect to the amount levers 29, positions clerks front and back indicators 52 and 53 and clerks type wheels 5 and 55 to letters of the alphabet used to identify the clerk making the transaction.

Each of the amount levers 29 (Figs. 1 and 4) carries a stud 55 which cooperates with a corre sponding arm 5i loose on the shaft 21, which is connected by a link 58 to an arm of a segmental gear or totalizer driving member 59 loose on a rod liil supported by similar plates 6i and iii! loose on a shaft 53, journaled in. the frames 2% and ill. The plates 5! and 62 are held in rigid relation to each other by the rod and by a similar rod t extending between rearward extensions of said plates, the entire assembly forming a roclrable frame adapted to rock the teeth of the segments. 59 into engagement with similar teeth of a corresponding totalizer gear 55 loose on a shaft 66 supported by the frames 2!) and l. The, gears mesh with pinions integral with corresponding totalizer wheels Bl free on a shaft supported by the frames 28 and 2!. A spring 'i t tensioned between each of the segments 59 and the levers 29 urges said segments and the arms 5? counter-clockwise as viewed in l to normally maintain said arms 5! in contact with the studs 55. It is therefore evident from the foregoing description that positioning the levers 2Q also positions the corresponding segments 5% to similar positions.

Each of the plates (ii and b2 (Figs. 1, 6, and 8) carries rollers 68 and 69, adapted to cooperate their respective companion plate cams if! and H fast on the main shaft El. As previously explained, rotating the main shaft Zl one clockwise revolution, by means of the crank 23, completes an operation of the machine. Initial movein nt of the shaft 21 causes the cams l6 and l l, in cooperat n with the rollers 68 and 69, to rock the fra Ile fi/Clk composed of the plates 6! and G2 counterclockwise to engage the teeth of the segments as with their corresponding totalizer gears 65. After the-segments 55 have been engaged with the gears 65, continued movement of the main shaft 2'! causes a cam F2 for each denominational order, secured on said main. shaft El, to engage corresponding rollers l3 mounted on the links and return the segments 59 from set positions clockwise to zero or normal position. This rotates the totalizer wheels 61 proportionate to the amount set up on the amount levers 29 to enter said amount in said totalizer wheels. A dwelling portion on the peripheries of the cams (2 causes the segments 59 to remain in zero position until further rotation of the shaft 2? causes the cams ill and "ii to rock the segment frame clockwise to disengage the segments 59 from the totalizer gears 65, whereupon the declining surfaces on the cams i2 permit the springs i i to return the segments 59 and their associated links 58 and arms. 57 counter-clockwise to their set positions, which positions are determined by the arms 51 contacting the studs 56.

Transfer mechanism The transfer mechanism used in the totalizer is of the Well known type shown in the United States patent to Marr, No. 570,178, which issued on October 27, 1896. Inasmuch as this type of transfer mechanism is old and well known, only a brief description will be given herein. Each totalizer wheel ril is provided with a pin 75, which, when the wheel is rotated through Zero, engages a projection of a latch it to rock said latch coLmter-clockwise against the action of a spring to disengage a shoulder on the forward end thereof from a projection on a transfer pawl 51 for the next higher order totalizer wheel El. This permits the tooth of the pawl "ll to engage the teeth. of a ratchet wheel integral with the corresponding totalizer wheel Bl. The main shaft 2f (Figs. 3 and 6) is operatively connected to the shaft 63 by means of an idler gear "is, loose on a stud in the frame 2i], which meshes with the gear 48 and a gear 86 secured on the right end of said shaft 63. Through the gearing just described, one clockwise revolution of the main shaft 2? drives the shaft 63 (Fig. 1) one revolution in a counter-clockwise direction causing a plurality of helically arranged transfer cams 8i, integral with said shaft, in cooperation with rollers 32 on their respective levers loose on a shaft B l supported by the frames 2d and ii to rock said levers 83 clockwise against the action of their respective torsion springs 85.

There is a lever 83 for each denominational order except the lowest order, and secured on the forward end of each of these levers is the corresponding transfer pawl l'l. It is therefore apparent that clockwise movement of the levers 83 carry the transfer pawls ill in unison therewith, causing all tripped transfer pawls to engage the ratchets of their corresponding totalizer wheels 6? to advance said wheels one position to transfer thereto amounts from the lower orders. the totalizer wheels 6'11 causes the bent-over ears on the pawls Tr to be raised above the shoulder on the transfer latches l6, thereby permitting said latches to be spring-returned into engagement with said ears torestore the transfer mech anism to untripped position before the end of a machine operation.

When any of the transfer latches it are not tripped, they move clockwise in unison with their respective transfer pawls Ti and hold the teeth of said pawls above the ratchets on their corresponding totalizer wheels to prevent the advancing of said totalizer wheels. The helical arrangement of the cams 8i (Fig. 1) causes the transfer mechanism for each denomination to be operated progressively from the lowest to highest denomination, thereby making for ease of opera tion and less strain upon the mechanism.

Initial movement counter-clockwise of the frame, composed of the plates 6i and 9t (Figs. 1 and 6), to engage the segments 59 with their corresponding gears moves the rod into the path of a foot-shaped projection 83 on the levers 33 to lock the settable levers connected mechanism against displacement while the totaliser is being actuated by the segments Return movement clockwise of the segment irame moves the rod 6:. out of the path of the projections 86 of the. levers 33.

The camming action of the ratchets on Drawer opening mechanism The drawer cabinet 23 encloses a cash drawer 81, which is opened near the end of machine operations in the following manner: The cam I2 (Figs. 1 and 6) for the units of dollars denomination carries a stud 88, which, near the end of machine operations, engages a downward extension 39 of a lever 99 loose on a rod 9| extending between the frames 29 and 2|, to rock said lever counter-clockwise as viewed in Fig. 1. Counter-clockwise movement of the lever by means of a link 92, connecting said lever to a drawer latch 93 loose on the shaft 63, lifts a shoulder 99 of said latch out of engagement with a latch plate secured to the drawer 81. This releases the drawer ill to the action of a cone shaped spiral spring 95, which immediately opens said drawer.

When the stud 88 moves beyond the extension 89 a spring 91, one end of which is connected to the link 92, immediately returns said link, the lever 99 and the latch 93 clockwise to normal position, which position is determined by a downward projection 99 on the lever 90, in cooperation with a collar on the rod 3 5. Return of the drawer latch 93 to normal position moves the shoulder 94 into the path of the locking plate 95 and closing the drawer 8? causes said plate 95 to by-pass the shoulder 99, which immediately moves into the path of said plate to latch the drawer 81 in closed position.

Signal device The present machine is provided with a signal device for visibly indicating when an amount, set up on the levers 29, has been registered or has not been registered.

A bail 99 (Figs. 1, 2 and 6) of a yoke composed of said bail and supporting arms I90 and IIJI, loose on the shaft 34, transverses all the alining levers 33, and is retained in resilient engagement with said levers by springs I93, extending between extensions of the arms I99 and IUI and the rod 9!. Moving any of the levers 29 causes the notches BI, in cooperation with the roller 32, to rock the corresponding lever 33 first counterclockwise as viewed in Fig. 1. This counterclockwise movement of the lever 33 imparts similar counter-clockwise movement to the bail 99 and the arms I99 and IUI. Counter-clockwise movement of the arm IIlI moves a projecting tooth I94 thereon out of engagement with a bentover ear I 95 on a bar I96, the upper end of which is pivotally connected to an arm I97 journaled on the shaft 49, and adapted to support a rear indicator I98 and a front indicator I99. The lower end of the bar I96 is bifurcated to straddle a stud I I9 in one arm of a bell crankl II rotatably mounted on the rod 9I. Disengaging the tooth I94 from the ear I05 releases the bar I 96 and connected parts to the action of a spring II 2 which urges said bar downwardly to turn the arm I 9'! and the indicators I 98 and I99 in a clockwise direction, as viewed in Fig. 1. The indicators I93 and I09 have printed thereon the legends Registered and Not registered, which are visible through windows H3 and II 4 in the cabinet 29, and clockwise movement of said indicators causes the legend, Not registered, to become alined with the windows II 3 and I I I.

The cam 12 (Figs. 2 and 6) for the hundred dollar order, carries a stud II5, which near the end of machine operations engages a downwardly extending arm of the bell crank III to rock said bell crank counter-clockwise. Counter-clockwise movement of the bell crank III' restores the tar I06 upwardly, causing the ear I05 to move beyond the tooth I94, whereupon said tooth is springreturned into the path of said ear to retain the bar I 96 and associated parts in restored position. Restoring the bar I96 upwardly returns the arm I91 and the indicators I08 and I99 counter-clockwise to cause the legend Registered? to be visible through the windows H3 and H4.

The amount indicators II (Fig. 6) and the clerks indicator 53 are visible through the rear window I I 3 and the amount indicators 39 and the clerks indicator 52 are visible through the front window IM.

Control lock The machine of the instant invention is provided with a control lock, which controls the operation of the machine, the reading of the totalizer wheels, and the removal of the cabinet. The control lock has three positions. When in its #1 position, as shown in Fig. 3, the cabinet is locked against removal and a shielding device obscures the totalizer wheels from view. When the control lock is in its #2 position the machine is locked against operation, the cabinet locking mechanism is moved to ineffective position, and the totalizer wheels are uncovered for reading. When the control lock is in its #3 position the machine is locked against operation, the cabinet is locked against removal, and the shielding device obscures the wheels of the totalizer against reading.

The control lock is mounted on the right frame 29 (Fig. 3) and the rotatable barrel thereof has integral therewith a disk IIB, carrying a stud II! which extends through an angular slot II8 in a lever I I9 fulcrumed on a stud I29in the frame 20. The lever I I 9 is connected by a link I2I to a locking pawl I22 pivoted on a stud I 23 in the frame 20 and is urged counter-clockwise by a spring I24. The stud III also extends through an irregular slot I25 in a cabinet locking lever I26 pivoted on a stud I2? in the frame 29. A locking projection I28 of the lever I29 cooperates with an annular groove in the rod 25, which, it will be recalled, in cooperation with the cabinet lugs 23, secures the cabinet 24 against removal. The lever I26 is connected by a link I29 to an arm I39, loose on the shaft 63, and the arm I30 is in turn connected by a link I 3I to a crank I32 secured on a short shaft I33 journaled in the frame 29. Also secured on the shaft I33 is an arm I34 connected by a link I35 to a totalizer wheel obscuring shield I39, rotatably mounted upon the shaft that supports the totalizer wheels 67.

The position of the barrel of the control lock may be changed by the possessor of a key I31. When the key I31 is in a vertical or #1 position, the stud I I'I is positioned as here shown and positions the lever I I9 toretain the tooth of the pawl I22 out of engagement with the gear I9 on the main shaft 21. The stud II! also positions the lever I26 to retain the locking projection I28 in the groove in the rod 25 to prevent the shifting of said rod, and thereby locking the cabinet 24 against removal. In this case the lever I 29, by means of the link I29 and associated parts, positions the shield I 36 (Figs. 1 and 3) between the totalizer wheels and a reading aperture I38 in the cabinet 24 to prevent the reading of said totalizer Wheels. The shield I39 when in position to prevent reading of the totalizer also, by means of an extension thereof (not shown). obstructs the opening for the totalizer reset wrench and there- 75 by prevents turning the totalizer wheels to zero at this time.

Turning the key I3'I ninety degrees clockwise from vertical or #1 position to #2 position rocks the lever HS clockwise to permit the spring I24 to engage the tooth of the pawl I22 with the teeth of the gear i9 to lock the main shaft 2? against rotation. Turning the key I31 to #2 position also rocks the lever I25 counter-clockwise to remove the locking projection 28 from engagement with the annular groove in the rod 25 and the lever E25, by means of the link I25 and associated parts, rocks the shield I36 clockwise to a position where it will not obstruct View of the totalizer wheels 6? through the aperture I 38.

Turning the key I3l ninety degrees counterclockwise, from its vertical position to position #3, causes the stud II'II in cooperation with the slot in the lever I E9 to rock said lever clockwise to permit the tooth of the pawl E22 to engage the gear it to lock the machine against operation. Turning the key if? to #3 position causes the stud I ll to ride in the arcuate portion of the slot 125 in the lever 525 thus imparting no movement to said lever I26, which remains in the position shown in Fi 3 to lock the cabinet against removal. In this case the link E29 and associated parts retain the shield i353 in the position shown in Figs. 1 and 3, to obstruct View of the totalizer wheels through the aperture I38.

Printer mechanism The upper amount type wheels 41 (Figs. 6 and 7) and the clerks wheel 54, in cooperation with an inking ribbon M2 and a platen block E43 of an upper printing hammer 9-34, are adapted to make imp ints on an issuing receipt, the web hit'of which is unwound from a supply roll Hi6, supported on a stud in the frame 2|, is threaded around various studs and between the type wheels 4?, 54, and 65 i and the platen I43, and then is guided into the opening of a chute I4l' secured to the frame 2I. After imprinting is completed, a receipt feeding mechanism, later to be described, advances the web 145 of the receipt material to feed the printed portion of said receipt web through the opening in the chute I47 so that said printed receipt may be severed from the web by means of a knife M8 secured to the chute I47.

The lower amount type wheels 48 and the 'clerks wheel in cooperation with the inking ribbon I42 and a platen block I49 of a lower printing hammer 558, are adapted to make imprints upon a detail strip I5I, which is unwound from a supply roll I52 supported on a stud in the frame 2i, threaded around various rolls which guide the detail strip between the type wheels and the impression hammer I50, and said detail strip is finally Wound onto a receiving roll I53. The receiving roll I53 is automatically rotated each machine operation to line-space the detail strip E52. The inking ribbon I42 is of the endless variety and is supported by a framework which may be easily and quickly removed from the machine when it is desired to change or adjust the ribbon.

In addition to the amount type wheels 4! and the clerks wheel 54, the stud 49 supports a plurality of consecutive number type wheels I54 (Figs. 6 and 7) having teeth therein which cooperate with similar teeth in drive gears 155, integral with ratchets I593 turnably mounted upon rod i t. The teeth of the ratchets I56 cooperate with the graduated tines of a feed pawl l5! pivoted on a stud I58 carried by a yoke 159', the

arms of which straddle the ratchets I56 and gears I55, and are rotatably supported by the rod 44. A spring ltd urges the yoke 55 counterclockwise into contact with a stationary stud it! in the frame 2!. An extension of the yoke I59 carries a stud I52 which cooper-ates with the periphery of a cam i63 secured on the main shaft 2?. Counter-clockwise rotation of the main shaft 2?, as here viewed, causes the high point of the periphery of the cam 563 to engage the stud N52 to rock the yoke !59 clockwise to advance the consecutive number type wheels I54 one step each machine operation. The feeding of the consecutive number type wheels I54 occurs after the hammer i 34 has completed its printing stroke. A plurality of manually set date wheels $54, in cooperation with a platen block H65 carried by the hammer M r, record the date on the web I45 of the receipt, at the same time the amount and consecutive number are being recorded. The hammer I44 is pivoted on the forward arm of a bell crank H56 loose on a stud it? in the left frame 2 I and said bell crank M38 is urged counterclockwise by a spring its to normally maintain a roller I68 mounted on a downward arm thereof in contact with the periphery of a cam I59 secured to the shaft 21.

When the machine is at rest, the high portion of the periphery of the cam I59, in cooperation with a stud Ilil in an arm Ill, loose on a stud H2 in the frame 2|, maintains a bent-over ear N3 of said arm in the path of a projection 54 on the bell crank I66. This obstructs clockwise or printing movement of the bell crank and the hammer M4, thereby preventing the platen blocks I43 and 55 from being inadvertently moved into contact with the receipt material with the resulting erroneous entry or smudging of said receipt material.

Initial main shaft 21 moves the high portion of the cam I69 out of the path of the stud lit to permit a spring H5 to rock the arm l'II counter-clockwise to move the ear H3 out of the path of the projection H4. Continued counter-clockwise movement of the shaft 2i and cam I69 causes the high portion of said cam, in cooperation with the roller I58, to rock the bell crank I68 and the hammer I 44 clockwise to imprint the amount, the clerks letter, the consecutive number and the date upon the receipt material.

Receipt feeding and electromechanisms After the impression has been completed, the receipt web is fed forwardly through the opening in the chute I41, and while said receipt web is being fed, an electro device prints various data of a descriptive or advertising nature on the face of the succeeding receipt. The receipt feeding and electromechanism will. now be described.

Referring to Figs. 5 and '7, secured on the shaft 21 is a partial gear I15, the teeth of which cooperate with the teeth in a gear I'I'I loose on the stud I12, and said gear I'I'I meshes with a gear I78 loose on the stud 49. The gear I78 meshes with a gear I19 rotatably supported by a stud I8Il, secured in the frame 2!, said stud also supporting the date wheels I54. Integral with the gear I79 is a receipt feeding disk I 90, which, in cooperation with a pressure roller I8I, is adapted to feed the receipt material. The pressure roller l8I- is rotatably supported by a stud I82 in an arm I83, pivoted on a stud I84 in the frame 2|. Said stud I84, in cooperation with a vertical slot in the hammer I44, also maintains the platen movement counter-clockwise of the blocks I43 and H55 in alinement with' their respective type wheels. The forward end of a pitman I is pivotally connected to the arm I83, while the rearward end of said pitman is slotted to receive a stud I86 in an arm I8'I loose on a stud I88 in the frame 2I. A spring I89, tensioned between the pitman I85 and the stud I86, urges the arm I89 and the pressure roller I8I clockwise to normally maintain said pressure roller in resilient engagement with the periphery of the feed disk I90. The periphery of a segment I9I secured to the gear I19 (Fig. 5), in cooperation with a cutaway portion I92 of the gear ITI, maintains the gears in proper relationship when the toothless portion of the gear I18 is opposite the gear Ill. The cutaway portion of the gear I16 causes the gear Ill and associated gears to remain stationary during initial movement of said gear I16 and the shaft 21.

Thus it is apparent that an electroprinting segment I93, integral with the gear Ill, and the i receipt feeding disk I remain stationary during initial movement of the shaft 21 and until the hammer I44 has completed its printing stroke. Continued rotation of the shaft 2'! causes the toothed portion of the gear I10 to engage the gear In to rotate the disk I90, which in cooperation with the pressure roller I8I feeds the web I45 of the receipt material, which is gripped between said pressure roller I8I and said feeding disk I90, through the opening of the chute I41. The receipt may then be grasped by the operator and severed from the web by means of the knife I48.

Inasmuch as one revolution of the feeding disk I90 (Fig. 5) is more than is'necessary to feed the desired length of receipt material, an undercut portion of the disk I90 suspends feeding of the receipt material at the beginning of rotation of said disk in order to obtain the desired length, of receipt. In addition to the cutaway portion of the feeding disk E90, a cam I94, integral with said "disk and the gear. I19, in cooperation with a flange I95 of the pressure roller I8I, lifts said pressure roller out of contact with the periphery of the feeding disk I90 when the cutaway portion of said disk is opposite said pressure roller. 7

During the feeding of the receipt, the gear I" (Figs. 5 and 7) and the electro I93 make one clockwise revolution, and during this revolution the electro I93, in cooperation with a pressure roller I96 supported between an extension of the arm I81 and an'arm I97, connected by a yoke I98 to said arm I81, prints various data upon the web I 45 of the receipt material. The electro printing mechanism works after the amount, clerks letter, consecutive number and date printing mechanism has functioned. Consequently, the data being recorded by the electro printing mechanism is not for the receipt being issued in this particular operation but is for the receipt of the succeeding operation.

Manual means is provided for disabling the electro printing mechanism and the receipt feeding mechanism and such mechanism will now be described. An arm I99 (Fig. 7) loose on the stud I88, has a bent-over portion which supports a set screw 2I2, which in cooperation with the yoke I 98 adjusts the pressure roller I99 in relation to the electro I93. A bent-over car 200 of the arm I99 cooperates with a shoulder on a latch 20 I' fulcrumed'on a stud 202 in the frame 2I. A spring 203, tensioned between the latch 20I and ,the arm I91, urges the shoulder of the latch 20I into contact with the bent-over car 208 and urges the pressure roller I96 away from the electro I93. When the shoulder of the latch 20I, in co-' operation with the ear .200, retains the arm I98 in the position here shown, the roller I96 is held in printing relationship with the electro I93. Manipulating the latch 20I disengages the shoulder thereof from the ear 209, to release the arm I99 and the yoke formed by the arms I81 and I9'I to the action of the spring 208, which immediately rocks the pressure roller I96 out of printing relationship with the electro I98. Counter-clockwise movement of the arm I81, upon disengagement of the latch 20I, causes the stud I86, in cooperation with the slot in the pitman I85, to shift said pitman rearwardly to rock the arm I83 counter-clockwise to move the pressure roller I8I for the receipt out of cooperative relationship with the feeding disk I 90. It is therefore obvious that this disables the electro printing and the receipt feeding mechanisms.

Amount type wheel aliner mechwm'sm Before the hammer I44 makes its printing stroke, a cam 204 fast on the main shaft 21, in cooperation with an upturned extension 205 of an aliner 208 loose on a stud 207 in the frame 2!, rocks said aliner clockwise against the action of a torsion spring 208 and engages said aliner with the teeth of the gears 46 which drive the amount type wheels, to lock said type wheels against movement during printing movement of the hammer I44. After the impression. has been completed, the contour of the cam 204 permits the spring 208 to disengage the aliner 208 from the gears 46.

Detail strip mechanism,

' At approximately the same time that the hammer I44 is functioning, clockwise movement of the shaft 93 (Fig. 7) causes a cam 209 secured thereon, in cooperation with a stud 2 I 0 carried by the hammer I50, to rock said hammer counterclockwise upon its pivot 29? against the action of the spring 208. Counter-clockwise movement of the hammer causes the platen I49 carried thereby to carry the web of the detail strip I5! and the inking ribbon I42 into contact with the lower amount type wheels 48 and the clerks wheel 55 to record the amount and the clerks letter upon the detail strip. After the impression has been completed, the receiving reel I 53, for the detail strip, is rotated counter-clockwise by mechanism not shown, to line space the detail strip. When the machine is at rest the high portion or the cam 209, in cooperation with a stud 2 in a downward extension of the hammer I50, retains the hammer I50 in ineffectiveposition to prevent said hammer from being inadvertently or accidentally moved to printing position and thereby making an erroneous entry or smudging the detail strip I5I.
