(Cl. lob-93) Claims.

I and a related spot being representative of the value or nature of the character.

Another object of the present invention is the provision of an indicating device controlled by a printed record made as an incident to the regular operation ofa key set machine.

A feature of the present invention is the pro duction of character recordings on a strip of transparent material, and the provision of optical devicescooperating with said strip for projecting an image of said printed characters. Associated with the transparent strip carrying the printed characters is a source of light which is directed through the strip to carry an image thereof by reflection along by a series of mirrors and through lenses to a translucent screen to reveal an enlarged, upright reproduction of the characters selected by operation of the machine. The screen is mounted in a recessed box to darken it and emphasize the lighted image.

Another further object-of the present invention is the provision of a series of spot printing slides geared directly to printing wheels so that adjustment of the wheels to character printing positions is communicated directly to said slides.

A still further object of the invention is the provision in a cash register of strip printing means for recording the data set up by the keys of said machine and then, later in each cycle, projecting an image of the data on the strip and maintaining said projected image until the machine is again operated.

Another object of the present invention. is the provision of a pair of transparent strips and controls associated therewith for recording and indicating impressions of classified data set up on a keyboard. The one strip which may be called an indicating strip has imprinted thereon all data set up in the form of characters and numbers which are then projected on an indicating screen. The other strip in the form of a code record only receives certain classes of data which appear thereon as characters and also as diflerentially located indicia or coded spots representative of the classified data. The operating transaction keys are divided into classified groups, only certain of which render effective the printing and feeding devices associated with the code strip. For example. cash," received on account, and "deposit keys may call for a code representation, while charge, C. O. D.," no sale and paid out" keys prevent printing on the code strip and feeding thereof. The indicating strip is line spaced on each cycle, while the code strip requires a long feed operation which is effected se-= lectively only after the code printing devices are operated.

An object of the invention is the provision of clutch mechanism between a code strip printer and feeder and a driver therefor; said clutch being operable selectively by certain transaction keys of a plurality of transaction keys of different classes.

Another feature of note is the provision of feeding devices for moving an indicating strip back and forth, from print receiving position to indicating position by a long feed operation and then back from indicating position to a position one line'space short of the printing position to receive another line of print.

A further object of the invention is the provision of a platen printing hammer operated by a double spring release for effecting an impression by an overthrown movement of the hammer. One spring impels a mover for the hammer, and another spring between said mover and hammer connects the two so that when the former is stopped suddenly, the inertia of the hammer car rles it further to strike, but said other spring instantly retracts it to allow strip feeding to take place.

An object of the invention is the provision of means for recording data by coded spot representations and related true numeral and letter representations. The true printed representations are of utility in indicating the amount and nature of the transaction that has been entered into the machine, and also as direct interpretations of the coded marks on the transparent strip wherethey both appear. The coded spot impressions are of utility in controlling other statistical machines to effect the punching of record cards or the making of other accounting records.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

Fig. 12 discloses examples of an indication strip and an associated code strip.

The cash register shown in connection with the present improvements is for illustrative purposes only as any other form of item entry accountnine digit keys, of which only one bank is shown in Fig. 2. These keys are indicated by reference numeral l6 and are depressed against the tension of their springs H to determine the difier ential movement of operating actuators l2. The keys ID are arranged with the 1 key near the bottom and the others progressing in value up to the 9 key at the top. The operation of any of these keys Ill in a bank elevates an associated arcuate detent 13 to release an actuator for operation. The actuators l2 are all dour-- naled loosely on a main shaft l4 and are provided with slidable looking or latching plates IS. The actuators I2 carry pivoted levers i band trip pawls 9 which are adapted to engage and be stopped by the inner end of any depressed key iii.

Slidably mounted on shaft ll are a series of latches 25, one for each detent it, Each detent holds a latch to the left with a hook 27 thereon engaging a flattened stud 28 on lever it. Whenever a key is depressed and the associated detent i3 is raised, latch 25 is released and moved to the right by spring 36 whereupon hook 2? is moved away from stud 28 and lever it which then permits latch plate l5 to move inward to hook a point 31 thereon with shoulder 35 and 75 thus connect actuator 92 to drive segment 23 for difierential movement. Restoring cams 38 fastened to shaft l5 cooperate with studs 39 on latches 25 to restore them near the end of the operating cycle.

When the trip pawl 9 abuts against a depressed key, the lever it and plate 15 is moved thereby,

outward and into one of a series of notches l1 of a plate i8, thereby locking the actuator l2 in a differentially adjusted position.

The main shaft I4 is arranged to be oscillated at each operation by a crank arm I9 connected through a link 26 to a second crank arm 28 rigidly mounted on an operating shaft 22 of the machine. Rigid on shaft I4 is a series of segments 23 one for each actuator I2 which together with depending projections serve to move the actuators i2 in opposite directions in a well known manner. It will be understood that although this mechanism is shown in connection with only one bank of keys, there will be an actuator l2 and a cooperating mechanism for each bank. The actuators l2 each carry a rack 26 which is adapted to control the setting of the usual totalizer element 28 and the printing devices of the present invention.

The operating handle 29 (Fig. l) of the cash register is provided with a. pinion 30 which meshes with a gear 3| which in turn' meshes with a gear 32. The gear 32 is secured to one end of a transverse shaft 33 and meshes with a gear 34 secured to the transverse shaft 22.

A change is made in the operating cycle of the cash register to allow more time for operation of the printing and indicating devices of the present invention. As arranged in Patent 580,378, the actuators l2 are restored in thefirst half cycle and then set differentially in the second half of the operating cycle according to the key settings. This is changed so that in the present disclosure the actuators l2 are set early in the cycle, and then restored in the second half of the cycle. The change is made by advancing the pinion 36 (Fig. 1) through degrees of movement and then reassembling the handle 2! thereto to make the midpoint of the usual cycle. the starting point of operations as presently disclosed.

It may be noted that when the segments 23 are in the normal home position, Fig. 2, they are lowered so that shoulders 35 formed on the segments will be engaged by the slides I5 of the banks in which keys have been depressed, so that the actuators l2 carrying the trip pawls 9 of the levers N3 of the banks in which keys are depressed, will be carried rearwardly distances determined by the values of the depressed keys which are abutted by pawls 9 when shaft I4 is rocked in a clockwisedirection.

Upon counterclockwise.rotationofishaft 22 by the handle 29 (Fig. '1) and gear" train 30. ill, 32 and 34, the segments 23, Fig. 2, are moved clockwise, carrying along therewith all released actuators l2 until the latch plates 15 thereon are opposite depressed keys I, at which time the plates l5 are moved into a related notch l1 and away from the drive shoulders 35. Thus, the actuators l2 and connected racks 26 are set difierentially in the first part of the operating cycle.

In the second half of the operating. cycle, shaft 22 is moved further in a counterclockwise direction, and arm 2! thereon is moved upward on the right side of shaft 22. Link 20 is drawn upward towards the home position, and the prosame reason, projections 24 move back slightly it).

away from the restored actuators i2.

Another change made in the actuating mechanism to suit the present requirements is the reversal of cams 38 and the placement of the studs 3! on the top of latches 25 rather than at'the bottom as shown in Patent 580,378. This is done to enable restoration of' latches 25 by a counterclockwise movement of shaft l4 near the end of the cycle, instead of restoration by a clockwise movement as in the patent. This change in restoration does not aflect the detenting action ofthe latches which are effective as in the usual construction.

From the foregoing, it may be gathered that the amount representing racks 2! are moved clockwise diflerential extents during the first half of the cycle, and then restored during the second half of the operation. It will now be explained how the movement of said racks is communicated to numeral and spot printing devices early in each cycle, so that printing may be effected on a transparent record 42, Fig. 5, at about the midpoint of the cycle, said transparent record then being fed to an indication projecting position while the racks are being reset late in each cycle. 7

Referring to the plan view in Fig. 4, it is seen that four amount racks 26 are spaced between a pair of main side frames 43 and H. These side frames carry a pair of shafts 45 and 48 on which there are pivoted four denominational gears l1, ll, 48 and 50 meshing with the units, tens, hundreds and thousands racks 2., respectively. These gears are connected by tubing to pinions 5|, 52, I3 and 54, each meshing with an idler gear 55 engaging a related pinion 55 on one of four numeral type wheels II. The printing devices are assembled as a unit on a pair of intermediate side frames 53 and it between which extend a shaft it on which the idler gears 55 turn, and a shaft II which supports the type wheels 51.

The type wheels are formed with ten equally spaced type faces bearing embossed digit -numeral configurations. Normally, the type is in horizontal alignment with the center of shaft 6|, Fig. 2, and facing the rear towards a flat platen 84. Any differential movement of racks ll causes a corresponding setting of the type wheels 51 into positions representative of the keys operated. In Fig. 3 the parts are shown in an operated position with the wheels positioned ready to print the amount 05.74.

Associated with the four type wheels 51, Fig. 3, are four spot printing bars N. These bars are slidably mounted in a comb guide OI which is fastened between frames 58 and 59 and formed with four recesses in which there are vertical ribs IT for engaging in a long notch in the bars to guide them vertically and hold them in place. Each bar 6! is formedwith a depending rack ll having teeth meshing with the pinion I! on a related type wheel 51. As a wheel is turned counterclockwise, Fig. 2, and set differentially,

an embossed spot printing type face ",Pig. 3,

thereon is positioned above the numeral printing line, a distance commensurate with the value of the numeral which is selected to be printed and indicated. For example, in Fig. 3 it is seen that with the highest order wheel at 0, the highest order spot printing bar is in its lowest position; and with the hundreds order wheel at "5" the related spot bar is raised with the circular marking face '0 five steps above the spot face at the right; and since the tens numeral is 7, the tens bar 6! is raised two steps above the size of the numeral. Because the strip 42 is printed while held in an upside down and reversed position, when the strip is viewed as seen in Fig. 5, the ink marks are on the back of the transparent material, and the spots are below the numerals with which they are associated. The portion II is a complete frame or picture of the amount 29.61 represented numerically and graphically on the film strip.

Since the spot printing bars 65 are in constant engagement with the type wheel plnions 5|, when these wheels are restored to zero at the end of each cycle, the bars are also brought down to the normal zero position.

Between the transparent strip 42, Fig. 4, and the printing wheels and bars, there is placed an inking ribbon II. This ribbon is a wide continuous band which is so arranged that it follows a substantially square path in a vertical plane across the rear of the printer. Two brackets I! are fastened to the outside of frames II and II, and the ribbon is fed around the beveled edges II and N, Fig. 3, of the extending part of each bracket. Extensions II and I. are formed ontelach bracket to confine the ribbon in a fixed D The ribbon I I, Fig. 1, is fed early in each cycle by being pinched and shifted between an extensionll'on a rotating rubber cylinder 1! and a roller ll. Cylinder I! is fastened to a gear 8| which is pivoted on stud 88 and in mesh with a gear" connected with drive gear II, and thus the cylinder is given a complete turn in a clockwise direction on each cycle. Roller 8| is pivoted on a segmental plate .2 which is fulcrumed at 83 on the right side frame 58, said sectorbeing adjustabiy held by a screw and slot fastening ll so that the roller it may be set in variable positions in the path of the yielding extension ll to vary the extent of the feed.

Roller ll projects through an opening ll, Fig. 3, in the left bracket I2 and presses part of the ribbon forward towards the feed extension ll. As viewed in Fig. 3, the ribbon is fed in a counterclockwise direction with the eflective lower horizontal part of the ribbon moving towards the right, then up and around the beveled comers 13 and 1| and across horizontally towards the left and then down past the feeding means.

After the type wheels I! and spot bars ll are set differentially, a printing impression is taken therefrom. The platen N is in effect a printing hammer, because in the middle of each cycle it is.

- thrown against the transparent strip 42 to press it against the ribbon and numeral type 51 and spot faces I behind the ribbon. A backing plate II to which the platen is fastened, is fixed to a pinion It raises rack It and bar I sothat 1s tube H which slides within another tube 08. The

two tubes are connected by a spring 5 which holds plate 88 normally pressed against the front of outer tube 88. This outer tube is supported by a casting 89 fixed between side frames 58 and 59. A horizontal cylindrical hole is formed in the centerof casting 89, and the tubes are slidable back and forth therein to effect printing; A compression spring 90 presses between a fixed cross bar 9! and a flange 92 on the end of tube 88 and tends to move the platen towards the printing position. Such movement is normally prevented by a tripping arm 93 pivoted at 94 and extending upward through an opening in casting $9 and through a slot in the bottom of the tube 88. The arm abuts against the rear edge of the slot and holds tube 88 and platen 04 normally retracted against the pressure of spring 90.

Movement of tripping arm 93 is governed by a cam 98 which cooperates with a lug 99 on the arm to first rock it in a clockwise direction and then at the middle of the cycle, when the type have been set differentially, lug 99 is suddenly permitted to drop off the high point on the cam, and spring 90 is then free to push the tubes and the platen toward the impression making position. It will be noted that during the first part of each cycle, cam 98 moves arm 93 gradually in a clockwise direction, and the arm pushes tube 88 toward the rear to retract it beyond the normal retracted position. Spring 95 causes the.

inner tube 87 and the connected platen 6 3 to follow the outer tube towards the rear. I

When the trip arm 33 is released by cam 90 and the tube 88 is permitted to fiy forward, the

movement of this outer tube is not sufiicient to bring the platen against the type. However, the inertia of the moving platen, plate and inner tube is persistent enough to stretch the inner spring 95 and move the inner tube and connected platen forward momentarily with respect to the outer.- Thus the platen 63 is thrown forward to tube. efiect a rinting impression and then spring 95 moves the platen back to free the record strip at for a feeding operation.

It may be noted that at the bottom of tube ill the slot encircling'the end of arm 93 is longer than the slot in the outer tube 88. This extra length permits relative movement between the tubes. The slots not only cooperate with arm as for restoration of the tubes, but they also act as keying means for preventing the tubes from tuming in the casting 89.

Cam 9% is attached to a shaft llll which is turned by a gear I52, Fig. 1. This gear 502 is rotated in a clockwise direction by a train of gearing comprising idler gears E03, l and I105, the latter ofwhich meshes with gear ti. I82 and gear 30 are of the same size so that one complete rotation of shaft MI is effected on each operating cycle. Gears I03, Hi l and H35 pivot loosely on studs extending from right frame 58.

The margins of the transparent record or film 62, Fig. 5, are formed with lines of feed perforations I00 which engage teeth on pairs of sprocket wheels I07 and H08, Fig. 2, attached to shafts m9 and l I0 pivoted in the intermediate side frames 53 and 59. The film is drawn from a supply reel H3 pivoted loosely at H t; and then it is caught on the guide sprockets I 07, passed between ribbon H and platen 6 5, down around feed sprockets I08 and finally wound on a storage reel l I fastened to a shaft Hi5.

The shaft M0, to which the feed sprockets W3 are attached, extends out of right frame 53, Fig. i, and has fixed thereon a pinion iii and an in- Gear 4 8,8437, ll @Q termittent locking plate I83. Cooperating with pinion iii and plate Ila are a partial gear II! and a locking disk E20 on a gear I2i in mesh withthe idler gear l03. Gear I2I turns freely on a stud H2 and is proportioned to turn gear 1 I 9 and disk I20 one complete revolution in a clockwise direction every time the handle 29 is turned. For more than half of each cycle, pinion II1 remains stationary and the record strip 42 is held still as the periphery of. disk I20 slides along one of the two arcuate indentations in plate II 0. It is only after printing has been effected that the cutout part of disk E20 is opposite the plate H8 so that the plate is unlocked when the teeth of the partial gear IIQ engage pinion II! and turn it and shaft H0 a half revolution in a counterclockwise direction. This movement of shaft 0 is suflicient to turn sprockets I 08, Fig. 2, and draw down strip 42 the distance of one printed frame, i. e., a space indicated by the bracket I0 in Fig. 5.

The slack in the advanced strip 42 is taken up on the storage reel II5 by an arrangement for automatically turning the reel as the sprockets I08 rotate. Fastened to shaft H0 is a pulley I22, Fig. 4, around which is drawn a belt M3 the other end of which passes around another pulley I24 fixed on the end of the storage reel shaft IIG.

Thus, reel I I0 is turned counterclockwise on each feeding operation. Any tendency of the reel II! to draw an excessive amount of film is compen-' sated for by the slippage of the belt I 23.

Devices are provided for indicating the amount "set up on the keyboard and impressed as printed numerals on the transparent record strip 42. The printed numerals on the transparent record are displayed by being reflected on a translucent screen I27, Fig. 2, mounted in a recessed shielded box I28 set into the upper part of the casin I25 with an opening 830 facing toward the front of the machine. The light defining the numerals on the screen I2! is projected through the record 42 and a series of lenses and mirrors before line of numeral type wheels 51 equal to the length of one frame on the record film 42, i. e., a distance equal to the length of feed 70, Fig. 5. Therefore, after each printing and feeding operation, the transparent record is positioned to bring the last line of printed numerals thereon opposite the slot I37, Fig. 2. Since the numerals on the record are quite small and since they are printed upside down, the light rays from the record are directed through enlarging lenses I39 and reflected on mirrors I40 and III before reaching the screen I27 where they define the printed numerals right side up. The rectangular lenses i539 are mounted in a holder I and lens H35 is held in holder I43, said holders being fixed between the side frames. Mirror I40 is attached to a cross bar M5 fastened tothe inner walls of the casing are, and mirror in is mounted in a similar fashion onbar I56.

Since the transparent record 42 remains in the advanced position after each operating cycle, and

since the light of lamp I34 is radiated as long as a main switch is closed, the indicated amount remains displayed on screen I21 until the machine is again operated to print other numerals on the record.

The foregoing portion of the description is concerned mainly with the production and use of a single transparent record strip 42 as set forth in Figs. 1 to 5. A modification dsclosed in Figs. 6 to 12 provides for the production of two transparent record strips I42 and I50, Fig. 12. Code strip I42 is similar to the strip 42, Fig. 5, except that transaction data is recorded thereon in addition to amount data.

Only certain kinds of transactions are recorded on the strip I42 for when other transactions are selected, the strip does not receive any printed impressions, nor is it fed. The other transparent strip I50 is used for indicating or display purposes, because on it are recorded all transactions and all amounts set up on the keyboard. In Fig. 12 it may be noted that only cashv receiving transactions are recorded on strip I42, but all transactions are printed on strip I50.

The keyboard of the modification, Fig. 6, is the same as that of Fig. l in three amount banks, but a bank of transaction keys I5I, I52 are provided in which the four upper keys I5I, identified as Credit, Deposit, Received on account and Cash keys, relate to money receiving transactions; while the five lower keys I52, identified as Charge, C. O. D.," No sale," Paid out and Refund keys, are concerned with outlaying transactions. The banks of amount keys and the transaction keys of Fig. 6 control the setting of the differential actuators I2 and operating racks 26 in the same manner as set forth hereinbefore.

In Fig. 10 it is seen that the racks 26 are geared to a set of three numeral print wheels 51 and a transaction print wheel 511, by means of the gearing 49, 50, 53, 54, 55 and pinions 56 such as the gearing previously described. However, the four print wheels 51 and 51T which are operated directly are not alone on shaft 6I, but this shaft is extended beyond frame 59 into another frame 59M, and a second set of printer wheels I51, I51T are provided to print on the transparent indication strip I50, Fig. 12, while wheels 51 and 51T print on the code strip I42. Wheels I51 and I51T are connected to related wheels 51 and 51T by means of a set of four telescopic tubes I54 so that any movement imparted to any of the wheels at the right of the machine may be communicated directly and positively to the related wheel at the left. Of course, the extra set of wheels I51, I51T, at the right in Fig. 9, are reversed in order with the transaction wheel I51T at the left, near the other transaction wheel 51T which is at the right of its related numeral wheels. These positions are made congruent by reversing the type faces so that the type on wheels I51, I51T appear erect from the rear, Fig. 9, while the type on wheels 51 and 511 are upside down.

The inking ribbon 1IM used with the type wheels of the modification in Fig. 9 is supported and operated in the same fashion as the ribbon 1I described hereinbefore, except for its greater length and the mounting of bracket 12 on frame 53M instead of frame 53 so that the horizontal portion of the ribbon is wide enough to pass behind all eight of the type wheels.

The spot printing bars 65, Fig. 9, are geared to type wheel pinions 53 in the usual way and supported in guide 68. The highest order bar 65 in stead of representing amounts, prints a spot which is representative of the transaction related to the amount recorded by the other three bars.

From observation of the views in Figs. 9 and 10 it is seen that the code strip I42 is printed by wheels and impression devices at the right side of the machine between frames 58 and 59. And the feeding of the code strip is governed by devices outside the right side frame 58. The other strip I50 is marked by wheels and impression devices at the left side, between frames 58 and 59M. Movement of this indicator strip I50 is controlled by mechanism supported outside the left frame 59M. The controls over the printing and feeding of the two strips are exercised separately, because non-printing control is effected at times in connection with strip I42, and the strips are fed different distances.

The impression effecting devices and feeding devices cooperating with the code strip I42 are the same as those described hereinbefore in reference to strip 42, and they are operated the same with the exception of a break in the driving connections leading to these two devices. Reference to Fig. '1 makes it clear that the drive gearing leading to the printer operating shaft IM and the feed operating shaft I III is the same with the exception of a normally disconnected clutch which is placed between drive gears I03 and I05. This clutch is operated to be connected for effecting printing and feeding of the transparent code strip I42 only when one of the four top transaction keys I 51, Fig. 6, is depressed.

In Fig. 6, it is noted that a. slide I53 is formed with two slots I55 and I56 which cooperate with a stud I56 and shaft I4, respectively, to guide the slide for downward movement at an angle. The top of the slide is widened and provided with a shoulder at I53 to lie in the path of spring pins I60 extending from the sides of four upper cash receiving transaction keys I5I. Depression of any of these four keys I5I serves to push slide I53 downward and rock an arm IGI counterclockwise, said arm being articulated with the slide by pivot I62 and fastened to a clutch operating shaft I63. Since the depressed keys I5I are locked down during a substantial part of each operating cycle, the operated slide I53 and arm I6I will also be held in a depressed position. A spring I41 restores the slide I53 and its connections as soon as the depressed key is unlocked.

In Fig. 7, It is seen. that the clutch operating shaft I63 carries a clutch closing lever I61 outside the right frame 58. Fastened to this frame is a fixed cylindrical clutch housing I68 which is formed with an opening I69 in alignment with the end of lever I61. Outside the housing I68, Fig. 9, are two gears I10 and HI loosely mounted on a stud I12 fixed on frame 58 and centralized with respect to the concentric inner wall of the housing. Gear I10 is the driven gear in mesh with pinion I05, and gear III is the gear to be driven so that its motion may be communicated to gear I03 which drives the printer and tape feed shafts.

Attached to the outer gear H0 is a tube I13, Fig. 7, which extends inward through gear HI and into the housing I66 wherein a notched clutch disk I14 is fastened to the end of the tube. Pivoted at I15 on the inner wall of gear I" is a clutch dog I16 with a hammer shaped projecting end I11 one side of which is aligned with the notch in disk I14, and the outer proiectin: side normally protrudes through the opening I69 in housing I68 and abuts against the end of lever I81 where it is urged by a spring I18 between the dog and a pin on gear I11.

Normally gear I10 and disk I14 tum freely without engaging dog I16 and gear "I. However, when one of the four upper keys II Fig. 6, are depressed, slide I53 is lowered, arm I'BI and lever I61, Fig. '1, are rocked counterclockwise, and the end of lever I61 pushes the end I11 of dog I16 into engagement with the notch in disk I14. When the operating handle is turned, gear I and disk I14 are rotated clockwise and carry the engaged dog I16 and drive gear I1I along therewith. In the initial part of the engaged clutch movement, the end I11 of dog I16 is moved away from the housing opening I69 and thereafter the end rides on the inner surface of housing I68 and is thus held in engagement with the disk. Gear I10 is proportioned to make two revolutions for each operating cycle. When the clutch is engaged and gears I10 and HI have turned through one revolution, the end I11 of the do passes opposite opening I69, but it cannot fall into the opening because the lever end remains lifted to close the opening until the keys I5I are released later in the cycle. Therefore the clutch remains engaged for the second revolution at the end of which, as end I11 approaches the opening I69 it is then clear and the dog is latched therein by spring I18, the dog then dropping away from the disk I'M which is stopped with gear I10 in the normal position.

Whenever gear III is driven, it operates gear I08 meshing with operating gears I02 and IZI; gear I02 turns the printer shaft I III to effect an impression of spots and numerals on the code strip, and gear I 2i operates the intermittent gearing to turn shaft lid for a strip feeding operation. t

The depression of any of the five bottom transaction keys I52, Fig. 6, relating to cash outgoing or charging transactions, along with depression of bail I86 and the rear bail, serves to hold the front bail retracted against the cross bar I85 of the middle bail I81. I

When shaft IOIM is turned in a clockwise direction, the rising edge of cam I98 cooperates with bar I99 to rock the entire impression assembly rearward against the tension of spring I90. Bail I81 is rocked clockwise because it is connected by link I94 to'the rear bail which is moved directly by the cam. The platen holder 186 is also rocked clockwise because it is urged by spring I95 to follow bail I81.

At printing time, the shoulder on cam I98 arrives opposite bar I99 and suddenly the entire assembly is released for movement to the left under the tension of spring I90. The two rear balls are stopped abruptly by a stop stud I89, but front bail I88 and platen I64 are carried on further by inertia to strike the record strip I50 and impress it against the ribbon and the adjusted type wheels I51 and I51T. As the platen strikes, spring I95is stretched to move the platen ball away from cross bar I85, but immediately thereafter the spring takes effect to draw the platen back away from tape I50 so that it may be fed.

of amount keys, causes adjustment of both sets of typewheels, but since clutch H6, H6 then remains disengaged, the code strip I62 is not pressed against the type, neither is it advanced. The other strip I50, however, is impressed against its adjusted type and shifted on every cycle, regardless of the nature of the transaction.

The devices for efiecting the printing impression on the transparent indicator strip I are shown in Figs. 6 and 10. Referring to the view in. Fig. 6 it is seen that a bar shaped platen I68 is held on a bail I86 comprising side arms loosely pivoted on a shaft I96 held in frames 68 and 59M. Behind platen bail I86 is another bail with side arms I8? loosely pivoted at I91 and formed with a cross bar I85 contacting the rear edge of arms, I86. The top of this second bail is connected by a link I83 to the top of a third bail composed of side arms I68 and I85 pivoted loosely on a shaft 90. Cross bar I98, Fig. 10, of the third bail cooperates with an operating cam I98 fastened to an operating shaft IOIM. This shaft is coaxially mounted with respect to shaft I III, but is not connected therewith or operated thereby. Shaft IOIM is operated by separate connections located outside the left frame 59M, and these connections are described more fully hereinafter.

Returning to consideration of the three impression controlling bails, Fig. 6, it is noted that the rear bail is urged into constant cooperation with cam I98 by means of a spring I90 which is connected to the top of arm I88. Another The connections for driving the printing control shaft IOIM are revealed in Fig. 8. There it is seen that a gear 34M is fixed to the operatingshaft 22 that is turned one revolution in a clockwise direction in each operating cycle. The drive from gear 34M to a gear 202 attached to shaft IOIM, passes through a train of idler gears I-8I, 205, 204 and 203. Since gear 202 is the same size as gear 34M, shaft IOIM and cam I98, Fig. 6, are turned one revolution every time the machine is operated.

Although the lines of print on the transparent indicator strip I50, Fig. 12, are spaced apart at regular intervals. the feeding devices cooperating with this strip must do more than line space the strip. An unusual movement of strip I50 is necessary because an impressed line of print must be moved down from a position opposite platen I68, Fig. 6, down opposite an indicator sight opening I3'IM, late in one cycle; and then, early in the next cycle, the strip must be moved upward to bring the line of print one line space or one frame below the printing line so that a new impression may be effected directly above the previous recording.

Strip I50 is guided and moved by pairs of sprocket wheels 201 and 208 fastened on an upper shaft 209 and lower shaft IIOM, respectively. A supply reel 2I3 holds the unused portion of strip I50 on a shaft 2I4; the printed part of the strip is wound on a storage reel 2I5 fixed to a shaft 2I8. Motion of shaft OM is communicated to shaft 2I6 by means of a belt 223 which passes around a pulley 222 on shaft IIOM and a pulley 224 on shaft-2H5. The supply reel 2I3 is also connected for movement in synchronism with the strip feed sprockets. In Fig. 8 it is seen that a belt I19 runs with a pulley I80 on supply shaft 2 and a pulley I82 on sprocket shaft 209.

Although feed shaft IIOM, Fig. 9, is coaxial with shaft IIO they arenot connected. Shaft H0 is supported in a bushing I83 on one side of spring I85, connected between a stud on the top II! rection and then in the other direction, the indicator strip I50 is raised and lowered from indication position to print receiving position and vice versa. The pinions are operated by a common rack slide 200 which is formed with a rack section 2I0 meshing with pinion I9I and another rack section 2 adapted to mesh with pinion I92. The rack slide is lowered and raised by means of a drive pin 2I2 mounted eccentrically on a cam disk 2" loosely pivoted on a stud 2I8 on frame 59M. Attached to disk 2" is a gear 2 I9 in mesh with a gear 220 fastened to the printer drive gear 202. Through the connections mentioned, disk 2" is turned one revolution in a clockwise direction on every operating cycle, and pin 2I2 thereon cooperates with a horizontal slot 22I in slide 200 to move the slide down in the first half cycle, and then upward in the second half of each operaticn.

Slide 200 is formed with vertical slots 225 and 225 through which there extend rollers 221 and 228 on bell cranks 229 and 230 that not only guide the slide in its vertical movement, but also tip the slide so that it engages alternately with the pinions I9I and I92.

Bell crank 229 is pivoted on a stud 23I on frame 88M and this crank is formed with an extending foot 232 which is struck by a shoulder 233 on cam disk 2I1 late in each cycle to rock the crank and roller 221 to the right, meshing rack section 2I0 with pinion I9I. The rack slide 200 remains engaged with pinion I9I during the first half cycle while said slide is being moved downward, said engagement being maintained because foot 232 rides upon the raised part of the periphery of disk 2I1. clockwise and strip I50 is raised to print receiving position. At the half stroke position, foot 232 drops off the raised part of the disk, and crank 229 rocks clockwise to disengage rack section 2I0.

The other bell crank 230 is pivoted on a raised center 235 on a bracket 238 fastened to frame 59M. An extending cam portion 231 on crank 230 rides on a low part .238 of the periphery of disk 2I1 until the midpoint of the operation, at which time, shoulder 233 strikes cam 231 and rocks crank 230 and roller 228 to the right, meshing rack section 2 with pinion I92. The rack slide 200 remains engaged with pinion I92 during the second half of each cycle while said Slide is being moved upward, said engagement being maintained because cam portion 231 rides on the raised part of the periphery of disk 2". In this way pinion I92 is turned clockwise and strip I50 is lowered to indicating position. Late in each cycle, cam 231 on crank 230 drops off a shoulder 239 on disk 2I1 and the crank rocks clockwise to disengage rack section 2 from pinion I92.

A link 240 is connected loosely on studs 242 and 243 on the ends of the arms of cranks 229 and 230 at the opposite sides of pivots 23I and 235. Through this link connection, movement of one crank to mesh slide 200 with one pinion will automatically swing the other crank to disengage the slide from the other pinion.

Although rack slide 200 moves equal distances downward and upward, the feed movements imparted from the gears I9I I92 to the two sprocket shafts 209 and IIOM differ because the top sprockets 201, Fig. 6, are smaller in diameter than the lower sprockets 208. The proportions are such that when sprockets 208 turn counterclockwise to lower the strip I50, it is fed the longer distance from the printing line to opening I31M; and when sprockets 201 turn clockwise to raise Thus the pinion I9I is turned counterthe strip, it is lifted through a shorter distance from opening I31M to one line space or frame length short of the printing line. Therefore the difference in extent of feed is equal to the length 24 I Fig. 12, of one frame on strip I50.

An indication is exhibited on the translucent screen I21, Fig. 6 in somewhat the same fashion as the indication already described with reference to Fig. 2. However there are some differences because the transparent strip used for indicating is the character bearing strip I50, Fig. 12, rather than the code strip I42. Reference to the type wheels I51, I51T, Fig. 9, reveals that the impression imparted thereby on the indication strip I50, appear in a left to right order from the rear and are in the correct erect position. Before exhibiting the characters so they read correctly when observed from the front of the machine, they must be reversed in the left to right order. This is done by means of a pair of slanted mirrors 2453 and 245L, Fig. 11, which catch the refiection of the characters on the strip I50 after the image passes through the enlarging optical device I44. The reversed image is reflected from mirror 2453 to mirrors I40 and HI and then against the translucent screen I21. The source of light is provided in the usual way by rays from lamp I34, Fig. 6, which pass through lens I43, against mirror I35 and through opening I31M, behind which appears the frame of characters printed on the transparent strip I50.
