18 Claims. (01.101-1-33) This case is a division of the application Serial No. 659,442, filed March 3, 1933.

. The invention relates to printing devices and means for feeding and ejecting'the record ma terial upon which the printed matter is impressed.

The devices are illustrated as part of a perforated card controlled tabulating machine.

An object of the invention is to provide an im-. proved form of automatic line spacing means. m Another object is to provide a simple and yet effective type of ejecting mechanism for feeding a printedform out of the carriage of the machine and picking up a new form and bringing it into position for the printing of the first item. 15 The -nechanism is constructed as a compact unit which is attached to and movable with, the

carriage frame. Wiring connections provide the means for establishing control between the regu lar tabulating mechanism and the record feeding 20 devices.

A feature of the-invention is the provision of. means for controlling the spacing of the record material before and after the printing of data. The controls may be adjusted to suppress the 5 feeding of the record material so that the data is printed in line with the last item. Other adjustments may be made so that a single or multiple line spacing operation may take place before and after the printing of the data.

30 The line spacing devices are manually adjusted to call for single, double, or triple spacing. The

effecting of such spacing is brought about under electromagnetic control and a single impulse through the magnet brings about the single or multiple spacing of the record material.

An object of the invention is to make the ejecting mechanism settable so that a variable number of items may be printed on a form before ejection. Other adjustments may be made in the control of the eject devices so that 'a form is ejected after a single printing impression under listing control. When listing, each item may be printed on a separate form.

5 Another feature of the invention is the automatic ejection of a, form when an impression is made at the bottom of the allotted printing area of such a form. This control is suppressed when the last item to be printed is the next to the last 50 item of a g oup. J

Another object of the invention is to provide a carriage with an adjustable head spacing feeding means to automatically carry the upper part of a form around to the printing line when the form is first entered into the carriage.

If the 5 form is part of a continuous strip, the automatic ejection device may be set to provide the same head spacing on all forms after the first form.

Another object of the invention is to provide an eject mechanism which starts and finishes the ejecting stroke with a, slow motion. The device is constructed so that the ejecting may occur at any point along the form and for any number of line spaces with the same type of feeding motion. The record sheet starts from rest and is gradually accelerated to the mid-point of the feeding cycle, and then during the second half of the feeding operation the sheet is gradually brought back to rest.

A feature of the invention is the automatic disabling of the detent cooperating with the platen line spacing shaft on the carriage during ejection. This eliminates the noise which would oth-. erwise attend ejection.

Another object of the invention is to provide 5 means for increasing the power of the carriage motor during ejection. This is done by automatically cutting out a resistance which is placed 'in series with the motor during operation in line spacing. I

The eject and line spacing devices are controlled by the presence of record cards in the tabulator. At the end of a run of cards the operating connections to the paper feeding mechanisms are disabled until other cards are analyzed.

Another feature of the invention is the provision of means to stop the tabulating machine during the operation of the ejecting mechanism when this mechanism is set to eject after every 40 item and for ejection at the end of a form. This is done to give the paper feeding devices time to function between the printing operations. of

' the regular tabulating machine. Devices are pro-' vided to delay the restarting of the tabulator until the eject mechanism is back in normal position.

These and other objects of the invention will be noted as the specification continues with reference to'the drawings which accompany the description and form part of the specification.

Referring to Fig. 1, it is noted that the platen 5| is mounted on the carriage unit which in turn is supported on the tabulating frame .52 in position adjacent the type bars 53. The tabulating frame 52 carries a carriage supporting frame 54 (Figs. 4 and 6) which is provided with a series of rollers 55 for guiding and supporting the movable carriage frame 56. Attached to the right end of the carriage frame 56 is the carriage side plate 51 (Figs. 1 and 7). At the other endof the frame 56 is attached a side plate 58 (Figs. 4, .15 and 19) acting as a support for the left end of the platen holding members. Swinging between the side frames is a rectangular bar 60 (Figs. 4 and 5) with ends in the form of trunnions 59 (Fig. l)

fitting in bearings on the side frames 51 and 58. It is about this bar 60 that the platen 5| is swung through an angle of about 180 degrees in a counterclockwise direction to bring the platen in position to receive the end of the record material. A bracket 6| (Fig. 19) attached to the left end of the rectangular bar 50 forms a support for one end of the platen, and the lever 62 (Figs. 2 and 7) forms the support for the platen at the other end. Parts 50, GI, and 62 form a bail which is pivotally .mounted at 59 and adapted to be swung toward the rear of the machine. with a handle 63 which may be grasped by the operator of the machine and swung in a counterclockwise direction through one half of a revolution to bring the platen in the upper position (Fig. 5).

' The lever 62 is held in normal position and the adjusted'position by a detent-ln the form of a bell The lever 62 is provided crank 54 (Fig. 2) pivoted at 65 on the carriage side plate 51. A roller 56 on the end of one arm of the crank 64 cooperates with a cam face 81 cut in the periphery of the lever 62 to hold the lever in normal position. A spring 68 attached to the bell crank holds the roller 66 in cooperation with 'the lever. i

A roll of record material 12 (Fig. 4) is suspended between a pair of brackets 13 attached to the carriage side plates 51 and II. The free end of the paper is drawn from the roll and passes over a guide I4 and then is directed at a tangent to the platen 5| (Fig. 4) and is drawn around the platen, under the feeding rollers I5 and out beneath the cutting plate I6. The paper guiding and feeding devices are moved along with the platen when it is lifted from the normal position. The paper guide I4 is mounted on side plates 11 (Fig.5) which are pivotally connected to the platen shaft 69 and to a shaft I8 suspended between the side plates TI and links I9 pivoted at 80 on the carriage side frames 51 and 58. By means of this form of toggle link connection, the paper guide is adapted to maintain the position at an angle tangent to the platen when it is in a normal feeding position (Fig. 4) and in the raised paper inserting position (Fig. 5).

The record paper is guided on the sides by guide members 8|0 in the form of bails which are sup-- ported on shaft I8 (Fig. 15). Each member is formed with two cars 8I5 encircling shaft I8. Between the ears 8I5 is another ear BIG formed as part of a bail formation ending in a handle 8|. A collar 8I'I on shaft 18 acts as a.space r between ear 8I6 and the left ear 8I5 on guide 8). Thus the handle and the guide are connected so that when handle 8| is moved along shaft I8 guide 8|0 is carried along therewith. An arc-shaped leaf spring 8I2 lies'under guide 8I0 and is held there by an extension 8I8 encircling shaft I8. The

' guide may be locked in any position by the depression of handle 8|. When the. handle is so moved, a cam extension 8| I, Fig. 5, formed on ear 8I6 presses against spring 8| 2 and flattens it against the under side of. guide 8 I 0. With ear 8 I6 and ears 8I5 pressed in opposite direction against shaft I8 they offer frictional resistance to.any attempt to move the guide along the shaft.

The pressure feed rollers I5 (Figs. 5 and '7) are supported on a shaft 82 which is held on the overturned projections 83 extending from a series of frames 84 pivoted at 85 on the rectangular bar 60. The pivot at 85 is formed by a projection on the frame 84 engaging a narrow slot cut in the rectangular bar 60.

The feed rollers I5 are normally held against the platen 5| by bow springs 86 each of which is tensioned and held between a notch 81 in frame 84 and a notch 88 cut in rectangular bar 69. The shaft 82 carrying the feed rollers I5 is provided with a. pinion 89 secured in line with a gear 90 (Fig. 7) secured to the platen shaft 69. By means of this connection the feed rollers 15 are rotated whenever the platen is turned for a record feeding operation.

A means is provided to disconnect the feed rollers from engagement with the platen when it is desired to insert or remove record material. Each of the frames 84 carrying the feed rollers is formed with a projection 9| (Fig. 5) which is alongside the lower surface of the rectangular bar 60. Between projection 9| and bar 60 is placed a shaft 92 with a. beveled side of theshaft cooperating with the end of the projection 9|. The

' shaft 92 is held in this position'by means of a groove 93 cut in the side of'rectangular bar 60 (Fi 15).

A thumb piece 94 (Fig. 2) is attached to the shaft 92 to operate the'same. When the shaft 92 is rocked, the frames 84 are moved in a clockwise direction (Fig. 5) aboutthe pivot 85 and withdraw the feed rollers I5 from the platen 5|.

Attached to the bar 60 (Fig. 7) are a series of spring members 95 pressing against the platen 5|.

A knurled knob 96 holds the member on the bar in various printing positions. The locking device 9 includes a notched bar 9'! (Fig. 3) which is secured to the underside of one of the flanges on the machine frame 54. Cooperatingwith the notches in the bar 87 is an arm 98 secured to a shaft 99 mounted in the movable carriage frame 56. A spring I90 tends to hold the arm 98 in one of the notches on bar 9?. Attached to the outer end of shaft 99 is an operating lever I 0| (Figs. 1 and 3) which may be lifted to disengage arm 98 from bar 91 and lowered to lock the carriage in position when it is located as desired by the operator.

The platen 5| may be rotated manually by means of the knob I02 (Fig.7) secured to the platen shaft 69. Anne adjustment of the line spacing may be had by rotating the knob I03 which is connected to the'platen shaft through pinion I04 and gears I05, I06.

The automatic-feeding of the platen is brought about by connections cooperating with the left .end of the platen shaft, as shown in Fig. 19.

' in the clutch plate I I I is a roller II3 mounted on a lever II4 pivoted at II5 on the bracket 8| supporting the platen. A spring I I6 urges the roller H3 into'depressions formed by teeth I12 and thus serves to locate the platen in a correct position for each line space.

When the platen is adjusted by hand, the clutch member H0 is forced to the left (Fig. 19) against the pressure of spring II! which normally holds it in engagement with the teeth on clutch plate I I I. A collar I I8 attached to the end of the platen shaft 69 forms an abutment against which the compression spring I I1 rests, theother end pressing against the clutch member I I0. The gear I08 is wide enough to maintain engagement with gear teeth I09 when it tion.

When the platen is swung to the upper position, the gear teeth I09 cooperate with the stationary gear I08 to turn the clutch member 0 in a counterclockwise direction (Fig. 6). This rotating movement is not transmittedv to the platen shaft because the shaft is held by -the cooperation between the star wheel II2 on clutch plate III and the detent II4.

On the downwardmovement of the platen there is a positive driving connection between gear I08 and the platen shaft 69 unless-the clutch member II 9 is shifted to the left 19) and disconnected from plate I I I. For this reason, lever I I9 (Figs. 6, 19, 20, and 21) is provided to shift clutch member H0. The clutch lever;is' ;,pivotecl at I20 (Figs. 20 and 21) on bracket I.2I secured to the trunnion 59 of. the rectangular bar. 60. Thus the lever is'connected to maintaina projection I22 in a slot I23 in clutch member-fl I0 as the platen is lifted or lowered into position. The clutch is out of clutching posilever I I9 is provided with a finger piece I24 (Fig. 75

'6) which may be manipulated to disconnect the clutch members when it is desired to back-space the platen.

An adjustable means is provided to control the time of ehgagement of the clutch member I I0 with the plate III as the platen is lowered, thus providing for the feeding of an inserted strip to bring any desired amount of head spacing above the printing line for the first item This is brought about by cammingthe lever II9 for a 'portion of the downward movement of the platen, and releasing the lever to permit the clutch connection to take hold during the remaining part of the motion. The cam surface I25 (Fig-'20) which cooperates with an extension I26 on the side of lever I I 9, forms an annular part of a disk I21 loosely pivoted about trunnion 59. The disk has a raised annular ring I28 which is knurled on the top face to permit circular adjustment by hand. A portion of the periphery of the disk is cut to form teeth I29 for locating and locking the disk in position. Cooperating with the teeth I29 is a locking member I30 slidably mounted on pin I3I projecting from carriage frame 58. A screw I32 may be tightened to hold member I30 against frame plate 58 after the disk I21 is brought 4 around to the desired head spacing position. As the disk I21 is moved in a counterclockwise direction '(Fig. the end I33 of the raised cam portion I is brought closer to the projection I26 on the lever .II9 when the lever is in the raised position. Then, as the lever is swung to thelower position alon with the platen, it reaches the end I33 whereupon the lever I I9 is-permitted to rock in a counterclockwise direction (Fig. 21) to shift the clutch member H0 and connect the platen so that it is driven from the time the projection I26 reaches the end I33 until the clutch lever is brought to the home position (Fig.- 6). Each of thenotches I29 represents a space of one line of head spacing. As shown in Fig. 20, the disk is adjusted to cause twelve lines of head spacing.

Another surface cooperates with extension I26 to cam lever II9 when a large range of head spacing movement is desired in rocking the platen back to normal position. This surface is presented by providing a cam 456 loosely mounted on shaft 59. The cam "is confined in its movement by a pin 456 extending from the side of disk I21. Should the disk I21 be set for a narrow head space, the extension I26 rides up' in a counterclockwise direction along the top of camface I25 and past the upper end of face I25 and over to the support furnished by the side of the top of cam 455,. The extension I26 is long enough to cooperate with the surfaces on face I25 and cam 455. If the cam .455 is not in position to act as an extended support -ated around .the platen and between the platen side plates 51 and 50-. Other automatic mechanism is provided to control rotation of the platen. This mechanism, which is about to be.

described, is compactly arranged and formed as a unit which is secured to the left side of the platen frame. The only driving connection between this automatic carriage control unit and the other carriage control mechanism is through the gear I01 (Figs. 15 and 19.).

The automatic carriage control unit is.pro-.

vided with manually -adjustable mechanical arrangements for varying the line spacing, determining whether ejection is to occur or not, setting the length of form to be printed upon and setting the number of lines to be printed before ejection. Other electrical switches may be adjusted to control the unit so that line spacing may or may not be effected by the occurrence of a total, spacing under listing and tabulating control, and spacing without cards in the tabulator. Adjustments may be made to secure ejection after every item, or ejection at the presentation of the end of a record form. A motor drives the mechanism in the iinit according to the setting of the controls mentioned. The entire unit is secured to the carriage frame and is moved along with the same to the various transverse printing positions.

The automatic carriage control mechanism is held in a' frame comprising a casting I34 (Figs. ,15 and 19) secured to the carriage side plate 58 by screws I36 (Fig: 6) and at other points by hubs between the casting and the plate. The casting frame I34 forms a support for the carriage motor CM (Figs. 1 and 8). A number of bosses project from the innerside of the casting frame and attached to some of these a riage control mechanism. A thumb screw I40 holds the cover I39 on the unit. A bracket I (Fig. 8) projecting from the carriage frame I34 forms a bearing for the shaft I42 of the carriage .motor CM. A pinion I43 on the motor shaft I42 meshes with a gear I44 pivoted at I45 on the side of the bracket MI. The gear I44 in turn meshes with another gear I46 attached to the shaft I41 which projects into the interior of the carriage control unit. A cover plate I48 (Fig. l)

is provided to conceal the gears I44, I46 and pinion I43.

The shaft I41 carries a pinion I49 (Fig. 8) which is connected to drive the line spacing and ejecting clutches in the unit. A gear I50 loosely mounted on a shaft I5I is in mesh with pinion I49 and is adapted to rotate continuously in a. counterclockwise direction as long as the motor CM is energized. Attached to the sides of gear I50 are ratchet gear I52 and a driving pinion I53. Adjacent the gear I52 is a cam' I54 (Fig. 15) loosely pivoted on shaft I5I. This cam carries a clutching pawl I55 pivoted at I56,. and a locking stud I51 for holding the cam in normal position. 'A compression spring I58 mounted in a stud I59 on cam I54 tends to engage pawl I55 with clutch gear I52, but an upwardly extending tail on the pawl is normally obstructed by-the end of a lever I60 connected to the armature I6I of the line spacing magnet IBM. The lever I60 is pivoted on a stud I62 and is urged in a clockwise direction against stop pin I63 by aspring I64. A latch I65 pivoted on stud I62 is urged into latching position by a spring .I66 .which holds it against a stop stud u -'I52, thus connecting the cam I54 to the driving '.gear I50. Asthe cam I54 rotates, it operates a lever I68 through a roller I69 on the lever in cooperation with the periphery of the cam; The lever I68 is pivoted on shaft I10 and is provided with an upwardly extending arm I1I which is cut to form three notches. A link I12, placed adjacent the lever I68, carries a pin I13 adapted to cooperate in lever I08.- The other end of link I12 is pivotally connected at I14 to a line spacing plate I15 loosely mounted on the platen feed shaft I16. The plate I15 carries a feed pawl I11 pivoted at I18 in the plate and adapted to cooperate with a ratchet-gear I19 fixed to shaft I16. This shaft is secured to gear I01 (Fig. 15) and thereby is adapted to turn-the platen.

From the connections vmentioned it may be noted that'as the cam I54 (Fig.

tion', pulling on link I12 and rocking the plate I15 so that pawl I11 advances the platen shaft one or more steps in a counterclockwise. direction. The amount of motion imparted to the platen feed shaft is determined 'by the adjustment of the end of link operates with any one-of the three notches in lever I68. If the pin cooperates with the notch nearest the pivotof the lever, the motion impart ed will amount to one line space. When the link is lifted to cooperate with the center notch the motion carried to the platen amounts to two line spaces. Lifting of the link to the highest position causes cooperation of the upper notch in lever I68 and connects the line spacing devices to produce three steps of motion. K

The manual adjustment of link I12 is brought about by'means of a manipulated arm I extending. from the side of the carriage frame I34 (Figs. 4 and 6). The arm I80 carries a knob I8I with a plunger which the operator may set to hold the arm in any one of the three positions identified on the side of the frame. -A shaft I82 (Fig. 9) is connected'to the arm I80 and has secured thereon another arm I83 cooperating with the underside of a pin I84 extending from link I12.

' By means of these connections the link I 12 is raised or lowered by arm I80. The link is held against the side of lever I85 secured to lever I68. A spring I86 attached to strip I85 urges the lever I68 in a clockwise direction and tends to hold roller I69 against wheel I provided forthe cam I54.

A spring I81 wound around stud I18 tends to move pawl I11 into cooperation with ratchet gear I19. However, in the normal position of the parts, a cam face on the lower portion of pawl I11 cooperates with a stud I88 projecting from the frame I34 in such manner that the pawl is forced away from the gear. The same stud I88 serves as a, stop for the plate I15 when it is drawn to the home position by a spring I89.

Secured to the side of ratchet gear I19 is a star purpose of normally backward movement of the line spac- -preventing v I I16. Cooperating with the star wheel ing shaft magnet LSM is enwith any one of the. notches 9) is rotated, the lever IE8 is rocked in -a counterclockwise direc- I12 so that pin I13 co- I68 by a guiding strip I90 is a pawl I9I loosely pivoted on shaft I92 and held into cooperation with the star wheel by spring I93. At certain times in the operation of the machine, the-pawl I9I is disengaged from the wheel I90 by an arm I94 secured to shaft I92 and carrying a pin I95 cooperating with the upper edge of pawl I9I, as explained hereinafter.

The view in Fig. 9 shows the line spacing deoperation of the machine when a magnet is energized for controlling such operation. The drivingpinion I53, which it is remembered is attached to gear I50, meshes with another gear I96 loosely pivoted on shaft I10. The gear carries attached thereto a ratchet gear I91. Located in alinement with ratchet I91 but normally out of engagement therewith is a ratchet pawl I98 pivoted at I99 on the side of an ejecting cam plate 200 (Figs, 13, 14 and 15) An extending tail on the pawl I98 (Fig. 8) cooperates with a lever 20I pivoted at 202 and attached to armature 203 cooperating with the ejectingcontrol magnet EM. When the magnet EM' is energized, lever MI is rocked in a clockwise direction releasing pawl I98 and clutching the ejecting cam plate 200 to the driving gear I96. The ejecting operation may be effected by a manual adjustment on the outside of the carriage control unit. .A button 204, extending out of 'the frame. I34, is connected to a link 205 which is guided bya stud 206 and formed with an abutment 201' in contact with a projection 208 extending from the bottom of lever 20I. A-

spring 209 holds the button 204 in an extended position. When the button'is depressed, the lever 20I is rocked just as though the magnet EM. were energized. 4

Before pointing out the connections for ejecting operation, it is believed well to mention that such an operation may take place at any point in the printing along the length of the record material, when initiated by the energization of ma net EM on the occurrence of a total, after a certain number of lines, or at the end of a form.

In Fig. 13 the ejecting devices are shown in the normal position. There it'is noted that a link 2I0 is articulated at 2 on side of plate 200' and at the other end is pivotally connected at 2I2 to the side of an ejecting frame 2I3 pivoted at 2 MI onthe frame of the control'unit. This rocking ejecting frame 2I3 is formed in the shape of j an arc with a series of teeth 2I4 cut in the inner side of the arc. Cooperating with these teeth (Fig. 11) is a block 2I5 formed'witha single tooth 2I6 adapted to ratchet over the teeth'2l4 and engage any one of the teeth as the link 2I1 carrying the block H5 is drawn along the inner surface of the arc during line spacing operation. The block .2I5 is loosely pivoted on link 2" by means of a stud 2I8 mounted on link 2". A washer 2I9 is secured to the stud by a screw and serves to hold the block 2I5'on the side oflink 2". -When the clutch connection comprising pawl I98 (Fig. 8) and ratchet gear I91 is made effective by the energization of themagnet EM or by pressing button 209, the plate 200 (Figs. 13 and 14) is connected'to rock in a clockwise direction 75 and moves link 2I8 and fr'ame'2I3 to theright with a gradually accelerated motion until the plate 288 has moved through an angle of ninety degrees and then the motion is retarded until the link is practicallyat rest as the plate reaches a position after 180? of motion. Then the same type of motion -is' repeated as the plate goes throughthe final 180 degrees'in arriving back to the home position after a complete revolution.

This type of motion is admirably fitted to cause the ejection of a record strip because it picksup the record material without a jerk and thus providesfor a firm grip on the material as it is started in' the feeding operation. The same type a of motion is in effect whether the sheet is ejected through a single line spacing motion or through the maximum distance possible to'eject.

Continuing now with outlining the connections of link 2I-8' to the line spacing devices for the purpose of ejection, it is noted that in its motion to. the-right (Figs. 13 and 14) the link carries along the ejecting frame 2I3 by rocking it in a clockwise direction about the pivot 2I4I. As this is done, the teeth 2 on the frame 2I3 engage the block 2I5 on the end'of link 2|] and move this link to the right. At the right end of link 2I1 there is connected a sector 228 loosely pivoted on a shaft'22l. The sector teeth are in mesh with a pinion 222 which maybe clutched to the line spacing shaft I16, which, as noted hereinbefore, seryes to space the platen through projecting from frame I34 and extending alongside thehubv on gear I81. An enlargedcollar224 on the shaft is seated in an embossed section of the center plate I38. Adjustably secured to the end of shaft I16 by a screw 226 is a'collar 226 providedwith a projection 221 adapted to cooperate with a notch 228 (Fig. 13) cut in the side of pinion 222. If the pinion 222 is held out of co-' operation with the projection 22'I ,the motion of sector 228 is not imparted to the line spacing shaft I16. The pinion 222 may be moved and held out of engag'er'nent'with the shaft I16 when it is desired to prevent ejection. The pinion is positioned byshaft 229 (Figs. 13, 14, and 15) carrying a positioning member 238 which cooperates with acircumferential slot 23I (Fig. 15) cut in the pinion 222.

An arm (new on the member m is slotted to cooperate with. a stud-24I located in the frame I38 and serving to hold the member in cooperation 'with the pinion. At the other end of the shaft 229 (Fig; 15) is mounted a knurled knob 232 attached to a positioning blank 233- cooperating with the pin 234 (Fig. 4) projectx ing from the side of frame I34. Another pin 236,

slightly higher than pin-23 4. cooperates with an elongated notch 236 out in the side ofmember 233. By meansof' the pins and the member 233.

the shaft 228 may be positioned axially in two different ways. If the knob 232 is grasped by the operator and puiled to the right (Fig. 15) and given *a coun terclockwise twist (Fig. 4) and pin 234 holds the shaft 228 in this extended position by obstructing the return movement' 'of the shaft to the left as seenin Fig.- 15. When the shaft is in this position, pinion 222 is declutched from the shaft I16 and automatic ejection is prevented.

If the operator wishes to set the devices for ejection, the knob 232 may be turned-in a clockwise direction until a notch 23'! (Fig. 4)' in member 233 coincides with pin 234. Then the shaft 229 may moveto the left (Fig. 15) carrying lever 238 "and pinion 222 to the left and engaging the pinion with the driving projection 22! on the line spacing shaft I18. A collar 238 (Fig. 15) on shaft .229 limits the motion of the shaft into engaging position. A compression spring 238 placed between lever 238 and frame I38, tends to hold the With the pinion so connected, any clockwise ejection movement of the sector 228- is transmitted through pinion 222, Fig. '19, shaft I18, gears I81 and I88, clutch member H8 and clutch III to turn theplaten shaft. and the converse is true in that if the shaft I16 is spaced in line spacing by means of the ratchet gear I19, the sector 228 will be advanced step by step in a clockwise di- '2, Figs. 11 and 12, whilemember 2I3 lies in a horizontal position. Then, at any selected point in the operation, and when tooth 2I8 is in mesh with any of the teeth 2, ejection is performed by rocking member 2I3, pushing link 2" connected thereto through tooth 2I8 and block- 2I8, rocking sector 228, turning gears 222, I81, I88, I89, H2 and the platen. I

' After sector 228 is moved in a clockwise direction (Fig. 14) it is restored by a compression spring 242. A plunger 243 pivoted at 244 on a stud in the sector plate 228 is provided with a shoulder against which one end of the compression spring presses. The other end of the 246 secured to frame plate I38 and drilled to receive the sliding end of a plunger 243. The

counterclockwise restoring movement of sector 228 under the urging of spring 242 does not effect any movement of the platen shaft. because the on member 2I3 form a perfect are about the center 246 where link 2II is secured to sector 228. The radius of the arcis substantially the same as .the length of link 21'! and thus all teeth 2 are equidistant from the center 246 in the sector 228 when it is in the extreme eject position.

The mechanism is designed in this way so that the sector 228 hever moves beyond a certain position in ejection regardlessof the-point at which ejection isstarted by the engagement of one of the teeth 2 with the toothed block 2I8 on link 2|! (Fig. 11). If, at the time ejection is initiated, the'block 2II engages a tooth 2 near the center 2I 4I, the ejection movement of sector 228 is short and the sector is rocked as far as the position shown in'Fig. 14. ,On the other hand, ifuponejection initiation the block 2-I8 engagesa tooth 2 near the end of member 2" removed from center 2I4I,'-the ejection movement of sector 228 is long, but the extreme ejection position of the sector is the same as tduring short ejection and the same as the" position shown in Fig. 14.

When the sector ,228 reaches the extreme adjusted position, Fig. 14, as result of a plurality of line spacing operations, devices are operated to prevent further line spacing operation. Line pinion m 'in engagement with the collar m.

35 compression spring rests in'a recess cut in a stud spacing at such a time would move the sector too far in a clockwise direction and demesh pinion 222. An interlock is provided to hold the armature lever I60, Fig. 8, in position to prevent the release of the spacing clutch pawl I55. The parts comprising the interlock include a bail 42I, Fig. 14, pivoted on a stud 422 extending from frame I34. An arm 423 on the bail is operated by the side 'of the sector when the sector is moved to the end as shown in Fig. 14. Another arm 424 on the bail is connected to a link 425 which slides along a pin 426 onthe frame. The end of the link abuts against an arm 421 (Fig. 8) attached to armature lever I66, preventing counterclockwise movement of the lever (Fig. 8) and keeping line'spacing pawl I55 latched out of operation.

' On the return counterclockwise motion of the mounted on the ejecting frame 2I3. A plate 241 screws secured to the casting frame.

connected to frame 2I3 by pin and slot connections 248 is formed with an arcuate slot 249 which engages the lower portion of block 2I5 (Fig. 11). When the plate is in normal position the tooth 2I6 is permitted to engage teeth 2I4. This relationship prevails as the ejecting frame member 2I3 is swung in a clockwise direction (Fig. 14). As the ejecting member is moved to the left in a counterclockwise direction, a pro jection 250 on plate 241 strikes a flipper 25I pivoted at 252 on a boss of casting I34. The

fiipper contacts against the stud. 253 which prevents clockwise motion of the flipper and causes a downward camming of the plate 241. The plate is permitted to move on the lever 2I3 by means of the pin and slot connections 248 and after moving a short distance, it is held in adjusted position by engagement of a latch 254 with a shoulder 256 on plate 241. The latch is pivoted on a stud 255 which extends from the side of eject'frame 2I3. The plate is thus held in adjusted position for most ofthe downward swing of frame 2H! until latch 254 strikes astud 251 projecting from the casting of the unit. Them-the latch is rocked in a clockwise three-'- tion to release plate 241 and allow spring 258 to draw the plate into normal position. When the plate is operated on the return motion of sector 220, the tooth 2I6 (Fig. 11) is moved out of cooperation with teeth 2I4 so that the left end of the link 2" may be moved along the slot '245 to bring the block 2I5 in position to cooperate with the teeth 2I4 at the left end of eject.

.justably varied to determine the length of the record sheet form to be printed upon in the machine.

The form may be shortened by stopping the sector 220 at any point along its travel towards the left (Fig. 12). For this purpose, a lever 259, pivoted on shaft 22I, cooperates with a stud 260 mounted on the side of sector 220. The end portion of the form length setting lever 259 is adapted to be adjusted around and held in any position along an are formed by a segment plate 26I. This segment plate is secured to the frame of the machine at 262' (Fig. 10) and 263 by On the outer edge of segment 26I are cut a series of ratchet teeth 264 each tooth representing a line space on the platen. A series of teeth in groups 1'1, and 18) representing inches of spacing are identified by numerals impressed on the side of the segment plate. An adjustable toothed member 265 'pivoted at 266 on lever 259 cooperates with the teeth 264 to hold the lever in any adjusted position. A spring 261 normally holds the toothed member 265 in engagement with the segment plate but it may be lifted and moved to the right or left to any position and locked therein to'form a stop for the return motion of sector closing of contacts to'form a completed circuit- For one form of control the contacts are closed as the printing on the record form approaches the end of the form.

These contacts 269 (Figs. 10 and 19) are-operated by plunger 210 guided by holes in studs 2 and 211 projecting from frame I38. The upper end of theplunger is contacted by an overturned shoulder on the contact operating lever 212 pivoted at 263. When the leveris rocked in a clockwise direction and the plunger is depressed, the contacts close to energize magnet EM and initiate an eject cycle of operation. The lever 212 (Fig. 10) is operated in such a manner by the striking of the pointed end'43il of a lever 213, fastened to sector 220, against a cam surface 214 projecting fromthe side of one arm of lever 212. The lever 213 is loosely pivoted adjacent the segment plate 26l on shaft 22I. The eject contact operating lever 213 is 'se-. cured to sector 220 by a screw 215 in stud 260 and may be adjusted around the sector by means of an arcuate slot 216 cooperating with the shoulder of screw 215.

In Fig. 12 the lever 213 is shown in such an adjusted position to' cause ejection before the usual time and thus provided for a larger un-" printed space at-the bottom of each record form. When aneject operation takes place, various electrical and mechanical devices in the machine must be operated to control carriage feeding, the operation of the carriage motor, the disablement of the line space latch, and the operation of the tabulating machine. The contacts are opened to cut out resistance in series with the carriage motor so that the motor may havethebeneflt of an increase in energy to carry the increased load which is presented when the platen is spaced through more than the usual distance. Other contacts are operated to cause a delay in the restarting of the tabulating driving connections during an eject operation. v v

Other disengagements must be eifected to free the line spacing shaft from .ratchet connections during ejection. These and other controls to be described hereinafter withreferene to the wiring diagram are effected by theQcam'faces formed on the periphery of plate mil which, as is noted fronn the foregoing section of the description, turnsNthrough a complete clockwise revolution during an ejecting operation.

Cooperating with the cam plate 260 is a threearmed contact operating lever 218 (Figs. 13, 14, The lever is attached to the shaft I92 already referred to in describing the mechanismin Fig. 8. The upper end of the lever 218 is lower end of link 28I (Fig. 10) is secured to a bail 283 pivotedon stud 284 and carrying an insulation block 285 which normally holds contacts 288 closed. Aspring 288 attached to bail 283 normally tends to holdthe contacts closed and the link .28I lifted with lever 218 pressing against plate 288. However, when the lever is cammed in a positive way by the plate 288,.link 28I is depressed and contacts 288' are allowed to open.

As explained-more fully hereinafter, the opening of these contacts causes the deenergization of a carriage motor relay to permit opening of contacts in series with a resistance normally decreasing the power of the carriage motor. The purpose of-these connections is to increase the power of the motor during ejection operation at which time the load is greater than when line spacing. When the relay is deenergized, other contacts are opened to prevent operation of the tabulating machine during ejection.

As the plate 288 continues to move in a clockwise direction (Fig. 14), at about the mid-point of the operation,another cam face 289 strikes the end of lever 218 and rocks it another step in a clockwise direction. When the lever is so operated, the arm I94 (Figs. 8 and 18), connected to the lever through shaft I92, acts on detent I9I (Fig. 8) to lower the sameand disconnect it from the star wheel I 98. ,This is done to permit a free return motion of the line spacing shaft I16 under control of the connections from the ejecting mechanism. v

The sector 228 (Fig. 14) ismoved in a-counterclockwise direction through link 2I1, eject frame 2I3, and link 2I8, when plate 288 is moved in a clockwise direction by ratchet gear I91. At the same time that the line space shaft is being reversed to'restore the ejecting mechanism and is freed. for such reversal by disengagement of pawl I9I, the platen shaft is held from backward motion by roller I I3 (Fig. in engagement with star wheel li2, preventing motion as the clutch collar I89 (Fig. 19) idly ratchetsover the teeth in clutch member Ill.

Near the end of the eject operation, an extending portion 298 (Fig. 14) on plate 288 strikes lever 218 and moves the same another increment of movement in a clockwise direction. This motion is used to close contacts 29I and open contacts 292 (Fig. 10). The lower end of lever 218 is formed with a projection 293 cooperating with a pin294 extending from the side of an arm 295 loosely pivoted on shaft I92.

A link 296 (Figs. 10 and 17) is articulated at one end on aim 295 and is connected at the other end by stud 291 on an arm 298 forming part of a bail 299 pivoted onstud 388 projecting from the frame I I38. The ball. 299 carries an insulation block 38I contacting the top of contacts 292. Since the lever 218 is rocked in a clockwise direction by the projection 298 (Fig. 14) arm 295 and link 298 (Fig. 18) is carried to the left to rock bail 299 ina counterclockwise direction about stud 388, releasing the pressure of insulation block 38l' from contacts 292 and allowing said contacts toopen. When the lever 218 is in normal position, the projection 293 is removed from the pin 294 so that the connections may be movedto close contacts 292. Such a movement is urged by spring 382; connected to arm 295. However, the connectionsmay be held from moving in this manner by the cooperation of an overturned portion 383 on arm 295 cooperating with the armature 384 attracted by magnet LCLM and movable about center 384i.

. This magnet is controlled by the closing of the lower card contact levers which are operated when cards are present under the lower sensing brushes in the tabulator. The magnet is energized early in each item entering cycle and attracts the armature 384, releasing arm 295 and permitting the closing of contacts 292. This condition of the contacts is maintained until a time near the end of an eject cycle when the projection 298 strikes lever 218 and, through the various connections described, restores-the linkage holding the contacts 292 closed, allowing the same to be opened. The function of the contacts in preventing paper feeding unless cards are in the tabulating machine, is explained more fully hereinafter with remarks referring to the wiring diagram.

At the same time that the lever 218 is'being rocked to its extreme clockwise position in effecting the opening of contacts 292, it also serves to operate to close contacts 29] (Fig. 18). This is done through the linkage including link 28I and bail 283 already described. The insulation block 285, after releasing contacts 286, moves to a'" neutral position as the ejecting operation takes place, and then, near the end of the operation, the block is lifted a slight amount by the clockwise motion of lever 218 to close contacts 29I. These contacts serve to initiate the automatic restarting of the tabulating machine so that cards are fed in regular operation afterth completion of an eject operation.

The automatic form ejecting mechanism is provided with means for disabling the starwheel detent on the platen shaft during ejection. 'Ihis is done to eliminate the noise which would otherwise be caused by the escaping of the roller 3 (Fig. 6) over the teeth of the star wheel II! as the platen shaft is rotated through a wide arc during ejection.

Referring now to Figs. 13 and 15, it is noted 'that a boss I384 on the end of link 2"! is adapted to cooperate with an arcuate surface on a lever 385 secured to one end of a shaft 388.-. As the ejection actuating frame 2" rocks about center 2I4I, the boss I384 strikes the lever 385 and rocks it through a short distance in a counterclockwise direction (Fig. 13) and maintains the lever in this position during the ejection stroke.

The shaft 388 (Fig. 15) is supported in the frame I34 and extends therefrom and carries a long arm 38'! (Fig. 6) which cooperates with an overturned shoulder 388 extending on the side'of line spacing detent II4. When the lever 385 is rocked during ejection, the am 381 is raised (Fig. 8) and the detent H4 is moved to position roller II 3 out 01" the path of the teeth on star wheel II2.

Beforeconsidering the wiring connections or the automatic carriage control devices, it is be- 'lieved well to outline the operation of the tabulating machine,with which the devices cooperate. The printing devioes of such a machine are illustrated in Fig. 1 and the adding, printing group control and other control devices are'shown diagrammatically in Fig. 33. Most of the matter of interest in connection with the present case is described in detail in Patent Ila-1,762,145.

, The general details of construction .of the ma- Gil chine are well known in the art and described in said patent, consequently there will be given herein only a brief explanation of such parts thereof as are necessary to an understanding of the present invention. It will be helpful in understanding the invention herein if it be noted that cam contacts identified by the letter L on the circuit diagram are operated by the tabulating mechanism through connections to the motor TM (Fig. 33) operative during listing operations, while the cam contacts identified by the letter P are operated by the resetting and total taking mechanism through the power of the motor RM.

Referring to Fig. 33, the record cards are succussively fed from a stack and advanced past the upper analyzing brushes UB and exactly one machine cycle later past the lower analyzing brushes LB. Suitable wires connect these brushes to a plugboard terminating in sockets 3l3 and 3l4 respectively. The plugboard also includes sockets 3l5 which are connected to the counter magnets AM. As the perforated cards pass the upper brushes, a card lever is engaged by the cards to cause closure of card lever contacts UCL and hold them closed as long as cards continue to feed past the upper brushes.

As the cards pass the lower brushes their index points instantaneously close circuits through the proper lower analyzing brushes LB to energize counter magnets AM. As usual, the timed energization of these magnets control mechanism for entering data corresponding to the card reading on the counter wheels. When any magnet AM is energized, it causes contacts 3I6 to close, energizing a printer magnet PM to select the type corresponding to the entered data for printing. In this fashion the accumulated or entered items may be listed.

In Fig. 1 is shown the printing mechanism through which the type bar 53 is positioned relatively to the platen 5| to bring the proper type 3|1 opposite the platen. The listing shaft 3 driven by the tabulating motor TM is provided with a cam 3 I8 cooperating with a roller 3l9 carriedby an arm 320 operatively connected to a shaft 32L As the came rotates, shaft 32! is rocked in a clockwise direction andan arm 322 secured thereto and linked. at its free end to printing crosshead 323 serves to raise the type bars 53 in synchronism with the movement of the record cards past the analyzing brushes so that the type 3H successively pass printing .position opposite platen 5|. The type bar 53 is arrested under control of printing magnet PM, which, when energized, attracts its armature 324 and through a call wire 325 releases latch member 32$. normally holding stop pawl 321.

When the pawl is so released, it is spring operated to engage the ratchet teeth 328 formed on the type bar 53 to prevent further upward movement of the type bar, thus holding a par-- ticular type 3" in printing position. The usual hammers 329 are provided to impelthe type against the platen.

During tabulating and listing operations themachine is driven by the motor TM (Fig. 33) controlled by a group of relays and contacts shown at the top of the sheet. The circuit which serves to is as follows: from left side of line 309 through motor TM, relay 330, clutch magnet 33l, motor relay 332, its contact points 333 (closed while the motor is running) wire 334, upper card lever contacts UCL, automatic control relay points maintain the motor TM in operation 335, stop key contacts 40!, wire 403, contact 405 (Fig. 32), wire 40B, switch .402, wire 401, wire 404, contacts P3 (Fig. 33) and the right side of line 3l0. This circuit maintains the motor TM in operation as long as cards continue to feed through the machine to hold contacts UCL closed.

During total taking operations the machine is driven by a reset motor RM controlled by a group of circuits, contacts and relays designated generally at 350. Shaft 3l2 (Fig. 1) is connected to be rotated by the reset motor during total taking. A cam 336 on the shaft cooperates with an arm 331 on shaft 32! to lift the type bars 53 in synchronism with the rocking of contact levers 338 (Fig. 33) These levers cooperate with the stepped cams 339 on the counter wheels and read card, brush LB, socket 3l4, connection wire 342,

socket 3l5, magnet AM, contacts 343, and wire 344 to left side of line 309.

Energization of magnet AM will cause opening of contacts 343 to interrupt this circuit and closure of contacts 3| 6 to complete the printing circuit from line 309, wire 344, contacts 3I6,print magnet PM, wire 345, contacts LP2, switches 345, 341, contacts 348, closed during listing operations, to line 3l0.

The major and minor automatic group control system used in the tabulating machine will be briefly described to bring out certain selective switching features. One form of such a control system is fully disclosed in British Patent No. 299,014. The usual automatic control magnets are shown at 43l (Fig. 33) and are provided with the usual series contacts to prevent sparking at the analyzing brushes. Each control magnet is adapted to be plugged in series between related upper and lower analyzing brushes to effect automatic control from any card col-' umn. The automatic control contacts 432 of i cards under the upper and lower analyzing brushes agree, all control contacts 432 which are properly plugged for automatic control, close 'at some time during the cycle, while when the control perforations fail to agree, one or more of the contacts fail to close.

The automatic control contacts 432 are all connected in series and a socket 433 is provided between each pair of them so that any number ofthem may be utilized and the control split into major and minor sections at any point. Under such arrangement when a group change occurs in the minor section total printing takes place under control of the counters of the tabulator and certain ones thereof are reset.

When a group change occurs in the major section, thesame procedure follows as on a minor change and in addition, totals are printed from
