This invention relates to devices for automatically feeding record material. The novel devices are illustrated as an attachment for a perforated card controlled tabulating machine.

An object of the invention is to provide an improved form or automatic line spacing means.

. Another object is to provide a simple and yet effective type of ejecting mechanism for feeding a printed form out of thecarriage of the machine and picking up a new form and bringing it intopodtion for the printing of the flrstitem.

The mechanism is constructed as a compact unit which is attached to andmovable with, the carriage frame. Wiring connections provide the means for establishing control between the regular tabulating mechanism and the record feedin 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 totals.

The controls may be adjusted to suppress the feeding of .the record material so that the total is printedin line with the last item. Other Bdjustments may be made so that a single or multiple line spacing operation may takeplaoe before and after' the printing of the total.

The line spacing devices are manually adjusted I to call for single, double, or triple spacing. The .eifectingof such spacing is brought about under 5 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 settabie so that a variable number of items or totals may be printed on a form before ejection. Other adjustments may be made in the control of the eject devices so that a form ed below the usual allotted printing area on the form with theitems which preceded the total.

Another object of the invention is to provide a carriage with an adiustable head spaci feed ingmeanstoautcmaticallycarrytheupperport and printed on the following sheet. but is print- SOIIIII. (crass-m of a form around to the printing linofwhen the form is first entered into the carriage. If the 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 veject 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 forany 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 eleminatesv the noise which would otherwise attend ejection.

Another object of the invention is to provide "means for increasing the power of the carriage motor during ejection. This is done byautomatically cutting out a resistance which is placed in series with the motor during operation inline The eject and line spacing devices are eontrolled 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 item and for ejection at the end of a form. This is done to give the paper feeding devices time to function betweentheprinting operations of the regular tabulating machine. Devices are provided to delay the restarting of the tabulator until the eject mechanism is back in normal position.

Another object of the invention is to provide devices for controlling ejecting after the printing of a minor or major total. These group control devices serve to prevent line, spacing operations on occurrence of totals in listing and tabulating operation. They also serve to prevent stopping of the'tabulator and ejection when a total is to be printed below the printing end of a form.

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 I! for guiding and supporting the movable carriage frame 56. Attached to the right end of the carriage frame is the carriage side plate 51 (Figs. 1 and 7). At the other end of the frame II 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 rectanfl ar r (Figs. 4 and 5) with ends in the form of trunnions I! (Fig. 1) fitting in bearings on the side frames 51 and 58. It is about this bar 56 that the platen II is swung through an angle of about "(I 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 5| forms a support for one end of the platen, and the lever 52 (Figs. 2 and 7) forms the support for the platen at the other end. Parts 58,, and "form a bail which is pivotally mounted at I and adapted to be swung toward the rear of the machine. The lever 82 is provided with a handle '3 which may be grasped by the operator of the machine and swung in a counterclockwise directionthrough one half of a revolution to bring the platen in the upper position (Fig. 5)

The leveri! is held'in normal position and the adjusted position by a detent in the form of a bell crank 64 (Fig. 2) pivoted at 55 on the carriage side plate 51. A roller 56 on the end of one arm of the crank 64 cooperates with a cam face 61 cut in the periphery of the lever 52 ,tohold the lever in normal position. A spring 53 attached to the bell crank holds the roller 50 in cooperation with the lever.

As the lever is adjusted, a concentric surface cooperates with the roller until the-lever reaches the adjusted position, then the roller drops into a notch "I to hold the lever and the platen in the record receiving position (Fig. 5). The platen shaft 69 is carried in a bearing Ill (Figs. 2 and 7) on the lever 52 and the other end pivots in a bearing H on the bracket N (Fig. 19).

Aroll ofrecordmateriall! (Fig.4) issua- .ioeasos ing and feeding devices are moved along with the platen when it is lifted from the normal position.

The paper'guide 14 is mounted on side plates 11 (Fig. 5) which are pivotally connected to the platen shaft 60 and to a shaft II suspended between the side plates 11 and links ll pivotedat II on the carriage side frames II and It. 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 P per inserting position (Fig. 5).

The record paper is guided on the sides by guide members III in the form of balls which are supported on shaft 18 (Fig. 15) These guides may be moved along the shaft by handles OI and each guide is locked in position when a cam face III on a handle wedges a leaf spring I2 against the flat side of the guide as the handle is depressed.

The pressure feed rollers I! (Figs. 5 and 7) are supported on a shaft 82 which is held on the overturned projections l2 extending from a series of frames ll pivoted at I! on the rectangular bar I. The pivot at ll is formed by a projection on the frame 84 engaging a narrow slotcut in the rectangular bar ll.

The-feed rollers "are normally held against the platen II by how springs 06 each of which is tensioned and held between a notch 81 in frame It and a notch 22 cut in rectangular bar 8|. The *ahaft "carrying the feed rollers I! is provided with a pinion 82 secured in line with a gear DI (Fig. '7) secured to the platen shaft 09. By means of this connection the feed rollers I5 are rotated whenever the platen is turned for a zrecord feeding operation.

A means is provided to disconnect the feed rollers from engagement with the platen when it is desired to insert or removerecord 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 80. Between projection 9i and bar 80 is placed a shaft 92 with a beveled side of the shaft cooperating with the end of the projection. The shaft 22 is held in this position by means of a groove 92 cut in the side of rectangular bar (Fig. 15). a

A thumb piece ll- (Fig. 2) is attachedto the shaft 22 to operate the same. when the shaft I2 is rocked, the frames are moved in a clockwise direction (Fig.'5) about the pivot 85 and withdraw the feed rollers 15 from the platen I.

Attached to the bar mg. "1) area series of spring members I pressing againstthe-platen II. A knurled knob 96 holds the member on the bar I. The end of the member may be used as a paper aliningguide and also to hold the paper against the platen as it is fed away from printing position.

the no es on bar 91.

spring I" tends to hold the arm 20 in one of Attached to the outer end of aft I. is an operating lever IM (Figs. 1 and 3.) which may be lifted to disengage arm 92 from bar 91 and lowered to lock the carriage in position when it is located as desired by the operator.

The platen-I may be rotated manually by means of the knob I02 (Fig. '7) secured to the platen shaft 69. A fine adjustment of the line spacing may be had by rotating the knob I" which is connected to the platenshaft through pinion I and gears I", III.

The automatic feeding of the platen is brought about by connections cooperating with the left end of the platen shaft, as shownin Fig. 19. The platen driving gear IIII (the actuation of which is described hereinafter) drives an idler gear ll8 (Fig. 15) loosely mounted on the trunnion 59 ofthe rectangular bar 82. The connection continues through gear I meshing with the teeth It! (Fig.

19) cut in a clutch member IIII, which engages a clutch plate III secured to theplaten shaft 69. The 'clutch plate III is formed with teeth H2 in the form of a star wheel. (Fig. 6). Cooperating with the star wheel teeth in the clutch plate end of the platen shaft 89 forms an abutment against which the compression spring II'I rests, the other end pressing against the clutch member H0. The gear I08 is wide enough to maintain engagement with'gear teeth I09 when it is. out of clutching position.

When the platen is swung to the upper position, the gear teeth I09 cooperate with the stationary gear. III to turn the clutch member III) in a counterclockwise direction (Fig. 6). This rotating movement is ;not transmitted to the platen shaft because the shaft is held by the cooperation between the star wheel I I2 on clutch plate III and the detent Ill.

On' the downward movement of the platen there is a positive driving connection between gear Ililand the platen shaft 69 unless the clutch member H0 is shifted to the left (Fig. 19) and disconnected from plate III. For this reason, lever II! (Figs. 6, 19, 20, and 21) is provided to shift clutch member IIII. The clutch lever is pivoted at I2II (Figs. 20 and 21) on bracket I2I secured to the trunnion 59 of the rectangular bar 60. Thus the lever is connected to maintain a projection I22 in a slot I22 in clutch member H0 as the platen is lifted or lowered into position. The clutch lever III is provided with a finger piece I2 (Fig. 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 engagement of the clutch member IIII 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 camming'the lever Ii! for through a wide angle.

a portion of the downward movement of the platen, and releasing the lever to permit the clutch connection to take hold during the re maining part of the motion. The cam surface I25 (Fig. 20) which cooperates with an extension I26 on the side of lever' H5, 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 92! for locating and locking the disk in position. Cooperating with the teeth In is a locking member 130 slidably mounted on pin III projecting from carriage frame 55. A screw II! may be tightened to hold member Ill against frame plate 58 after the disk I21 is brought around to the desired head spacing position. As the disk I2'. is moved in a counterclockwise direction (Fig. 20) the end I33 of the raised cam portion I25 is brought closer to the projection 525 on the lever H9 when the lever is in the raised position.

Then, as the lever is swung to the lower position along with the platen, it reaches the end I33 whereupon the lever III is permitted to rock in a counterclockwise direction (Fig. 21) to shift the clutch member I I and connectthe platen so that it is driven from the time the projection I28 reaches the end I33 until the clutch lever is brought to the home position (Fig. 8). Each of the notches 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 I! to earn lever H9 when a large head spacing movement is desired'in rocking the platen back to normal position. This surface is presented by providing a cam 455 loosely mounted on shaft 58. The cam is confined in its movement by a pin 456 extending from the side of disk I21. -A pin 451 on the cam cooperates with the extension 126 so that the cam face I25 is in eifect extended when lever H sweeps past the end of the same, as the lever is supported The angle of movement is greater than 180, therefore cam face I cannot be extended to act throughout the entire stroke. The cam 455 acts as a telescopic extension in extending the lever supporting cam face on disk iEI for narrow head spacing. When adjusted for wide head spacing the cam 455 is moved out of the way on the clockwise motion of lever H9 when extension I26 strikes pin 451. x

The mechanism described hereinbefore' is situated around the platen and between the,

platen side plates 5I-and 55. 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 IIII (Figs. 15 and 19).

The automatic carriage control unit is provided with manually adjustable mechanical arrangements for varying the line spacing, determining whether ejec'tion 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 I a,ooo,sos

may or may not be effectedby 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, ejection according to the occurrence of minor or major group control changes, or ejection at the presentation of the end of a record form. A motor drives the mechanism in the unit 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 55 by screws 316 (Fig. 6) and at other points by hubs between the casting and the plate. The casting frame I44 forms a support for the carriage motor CM (Figs. 1 and 8). A number of bosses project from the inner side of the casting frame and attached to some of these is a center plate I" (Figs. 13 and 19) which acts as a support for many of the shafts in the unit. The mechanism projecting beyond the plate Ill -is protected by a cover I" (Fig. 19) which coincides with the contour of the frame I34 making an enclosed box-like unit of the carriage control mechanism. A thumb screw I40 holds the cover I" on the unit. A bracket I (Fig. 8)

projecting from the carriage frame I34, forms a bearing for the shaft I41 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 I. The gear meshes with another gear I46 attached to the shaft'I4I which projects into the interior of the carriage control unit. A cover plate I45 (Fig.

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

The shaft I4I carries a pinion I49 (Fig. 8) which is connected to drive the line spacing and ejecting clutches in the unit. A gear I5II 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 I55. Adjacent the-gear I52 is a .cam I54 (Fig. 15) loosely pivoted on shaft I 5 I. a clutching pawl I55 pivoted at I55, 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 conne'cted-to-the armature I SI of the line spacing magnet LSM. The lever IN is pivoted on a stud I52 and is urged in a clockwise direction against stop pin III by a spring I54. A latch I85 pivoted on stud. Iii-is urged into latching position by a spring I55 which holds it against a stop stud I51 (Fig. 15).. The shoulder on the latch cooperates with a -flat face on stud I51 and serves tohold cam I54 from rocking counterclockwise when declutched.

When the line spacing magnet LSM is energized, the lever I" (Fig. 8) is rocked in a coun I in turn.

This cam carries terclockwise direction, releasing the clutch pawl I55 whichthen engages the ratchet gear III,

thus connecting. the cam I54 to the driving gear I50. As the cam I54 rotates, it operates a lever aooaaoc an upwardly extending arm "I which is cut to form three notches. A link I12, placed adjacent the lever I". carries a pin I13 adapted to cooperate with any one of the notches in lever I. The other end of link I12 is pivotally connected at ill to a line spacing plate I15 loosely mounted 'on the platen feed shaft I". The plate I15 carone 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 I12 so that pin I13 cooperates with any one of the three notches in lever I68.

If the pin cooperates with the notch nearest the pivot of the lever, the motion imparted 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.

The manual adjustment of link I12 is brought about by means of a manipulated arm I" extending from the side of the carriage'frame I (Figs. 4 and 6). The arm Ill carries a knob m 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 tothe arm I and has secured thereon another arm I cooperating with theunderslde of a pin Ill extending from-link I12. By means of these connections the link I12 is raised or lowered by arm I. The link is held against the side of lever I by'a guiding strip I85 secured to lever I68. 'A spring!" attached to strip I85 urges the lever I68 in a clockwise direction and tends to hold roller I" against cam I H. i

"A spring I81 wound around stud I1l=tend s 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 I" projecting from the frame I 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 I".

Secured to the side of ratchet gear I18- is a star wheel I90 provided for the purpose of normally and carrying preventing backward movement of the line spacing shaft I16. Cooperating with the-star wheel I is-a pawl IOI loosely pivoted on shaft I02 and held into cooperation with the star wheel by spring I. At certain times in the operation of the machine, the pawl IOI is dise ilaged from the wheel Ilflby an arm Ill secured to shaft I92 a pin it! cooperating with the upper edge of pawl IOI, as explained hereinafter.

The view in Fig. 9 shows the line spacin d9? vices in an operated position. it is noted the manual adjustment is set n a tw 91 three lines. The lever I is. rocked by the cam so that the link is to the left and feed pawl I11 engages the ratchet 'I1l fcr" the turning of the shaft I".

'riving back to I53, which it is remembered is attached to gear a v I50, meshes with another gear I" loosely pivoted onshaft I10. The'gear carries attached thereto a ratchet gear I81. Located in alinement with ratchet I91 but normally out of engagement therewith is a ratchet pawl Ill pivoted at III on the side of an ejecting cam plate 2 (Figs. 13, 14, and 15). An extending tail on the pawl I" (Fig. 8) cooperates with a lever 2IlI pivoted at 202 and attachedto armature 202 cooperating with the ejecting control magnet EM. 'When the 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 adjustmenton the outside of the carriage control unit. A button 2, extending out of the frame I, is connected to a link which is guided by a stud 208 and formed with an abutment 201 in contact with a projection 208 extending from the bottom of lever 2. A spring 208 holds the button 2 in an extended position. When the button is depressed, the lever "I is rocked just as though the magnet EM were energized.

Before pointing out the connections for eject-- ing operation. it isbelieved 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 magnet 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 2III is articulated at 2 on side of plate 2" and at the other end is pivotally connected at 2I2 to the side of an ejecting frame 2I3 pivoted at 2III on the frame of the control unit. This rocking ejectframe 2i! is formed in the shape of an arc with a series of teeth 2 cut in the inner side'of the arc. Cooperating with these teeth (Fig. 11) is a' block 2i! formed with a single tooth 2|. adapted to ratchet over the teeth 2 and engage any one of the teeth as the link 2" ca'r- -means of a stud 2i! mounted on link 2". A

washer 2i! issecuredto thestudby a screw-and serves to hold the block 2" on the side of link- 2". When the clutch connection comprising pawl leaks-1g. a) and ratchet gear m is made eifective by the energization of the magnet ml or by pressing button-2ll, the plate 2 (Figs. v

13 and i4) is connected to-rock in a clockwisedirection and moves link 24.. and frame 2|! to the right with a v the plate 2ll-haa moved through an angleof ninety degrees and then the motion is retarded until the link is practically at. rest as the .plate reaches a position after 180 degrees of motion.

Then the same typ of motion is repeated as the plate goes through the final 180 degrees in arthe home position after a complete revolution. 7 v

This type of motion is admirably fitted to cause the ejection of a record strip because it picks up the record material without-a jerk and thus magnet EM is energized, lever 2II is mined in'a gradually motion until provides for a firm grip on the material as it is 7 inbefore, serves to space the platen through tion of the center plate I88.

'lheformmaybeshortenedbyswpl lth sector ill at any point along its travel towards ill each tooth representing a line space on the platen; A series of teeth in groups representing inches of spacing are identified by numerals impressed on the side of the segment plate. An

adjustable toothed member ill pivoted at ill on lever ill cooperates with the teeth ill to hold the lever in any adjusted position. A spring ill normally holds the toothed member ill in engagement with the segment plate but it may be lifted and moved to the right or left to anyposition and locked therein to form a stop for the return motion of sector iil, thus determining the length of the stroke for ejection on the followlng operatio'n. A stud ill on lever ill is slotted to engage the inner arcuate surface of segment plate. ill to hold the lever against the side of the plate. a

As explained hereinbefore, the ejecting operation is controlled by the energi'zation of magnet EM. This magnet is energized at various times according to the setting of the controls and the 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 ill (Figs. 10 and 19) are operated by plunger ill guided by holes in studs ill and ill projecting from frame Ill. The upper end of the plunger is contacted by an overturned shoulder on the contact operating lever ili pivoted at ill. When the lever is rocked in a.clockwlse direction and the plunger is dep. the contacts close to energize magnet EM and initiate an eject cycle of operation.

The lever'ili (Fig. 10) is operated in such a manner by the striking of the pointed end I of a lever ill, fastened to sector iil, against a cam surface ill projecting from the side of one arm r f lever ill. The leverill is loosely pivoted adlament the segment plateill on shaft ill; The eject contact operating lever ill is secured to sector 220 by a screw ill in stud ill and may be adjusted around the sector by means of an arcuate slot as cooperating with the shoulder of screw i'll.

In Fig. 12 the lever in is shown in such an adjusted position to cause ejection. before the usual time and thus provide for alarger un printed space at the bottom of each record form. When an eject operation takes place,-various' electrical and mechanical devices in "the machine must be operated'to control carriage feed-- ing, the operation of the carriage m'otorpthe disablemcnt of the line space latch, and the ow tion of the tabulatins machine. Tbe'contacts are opened .to cut out resistance in series with;

the

tance; .Other contacts are operated to cause a.

delayintherestartingof'the tabulatingdriving connections during an eject operation. Other disengagements must be effected to free the line spacing shaft from ratchet connections during "ejection. These and other controls to be described hereinafter with reference-to the wiring diagram are eilected by the cam faces formed on the periphery of plate ill, which, as is noted from the foregoing section of the description, turns through a complete clockwise revolution 7 during an ejecting operation.

Cooperating with the cam plate ill is a threearmed contact operating lever ill (Figs. 13, 14, 1'1, and 18). The lever is attached to the shaft ili already referred to in describing the mechanism in Fig. 8. Theupper end of the lever ill is formed with a projection ill which acts as a tacts ill closed. A spring ill attached to bail,

ill normally tends to hold the contacts closed against plate ill. Ho wever, when the lever is cammed in a positive way by the plate ill, link ill is depressed and contacts ill are allowed to.

and the link ill lifted with lever ill pressing 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.

When the relay is deenergized, other contacts are opened to prevent operation of the tabulating machine during ejection.

As the plate ill continues to move ina clockwise direction (Fig. 14) at about the mid-point of the operation, another cam face ill strikes the 7 end of lever ill and rocks it another step in a clockwise direction, When the lever is so operated, the arm ill (Figs. 8 and 18), connected to the lever through shaft lli, acts on detent Ill (Fig. 8) to lower the same and disconnect it from the star wheel ill. .This is done to permit a free return motion of the line spacing shaftlll under control of the connections. from the ejecting mechanism. 1

The lectd! m (m. 11) is restored in a counterclockwise direction by spring ili p back through link ill to follow elect frame ill, and link ill, when plate ill is moved past llfl'degrees in a clockwise direction by ratchet gear Ill.

Atthesametimethatthel'everfltisbeing rocked to its extreme clockwise position in eiiecting the opening oi contacts 202, it also serves to operate to close contacts "I (Fig. 10). This is done through the linkage including link I" and ball I" already described. The insulation block 2", after releasing contacts 2. moves to a neutral position as the ejecting operation takes place, and then, near the end oi the operation, the block is liited a slight amount by the clockwise motion oi lever 218 to close contacts "I. These contacts serve to initiate the automatic restarting ot the tabulating machine so that cards are fed in regular operation after the com pletion of an elect operation. a

The automatic form ejecting mechanism is provided with means for disabling thestar wheel detent on the platen shalt during election. This is done to eliminate the noise which would otherwise be caused by the escaping oi the roller ill (Pig. 6) over the teeth of thestar wheel msthe platen man is rotated throimh a wide arc during election.
