'10 Claims. 1
The invention relates to the paper .feed mecha nismof accounting and'like machines and more especially to the 'long feed mechanism for imparting occasional feeds to the paper of greater extents than the ordinary line spacing.
It is the principal object of the .invention to improve apparatus of the indicated class in several respects which will be apparent from the following description and claims. The general organization of the mechanism has been improved, and provision .is made for some operations not obtainable with prior devices of a similar type.
Also some of the functions are accomplished by improved means, :and provision is made for more flexibility in adapting or setting .the mechanism'to meet the various requirements of differ- 'ent pieces of work.
To the above and other ends, the invention consists in certain .features of construction and combinations and 'arrangmen'ts of -parts, all of which will be "fully described "herein and particularly pointed out in the claims.
By way of illustration, the "novel mechanism is shown applied to the machine known commercially as the Powers alphabetic and numeric tabula'tor.

The .tabulating machine In the drawings, the invention is shown as applied to a Powers No. 3 alphabetic and numeric 'tabulating machine, of which Fig. 1 is a partial and more or .less schematic illustration in .section as viewed from the right. For brevity, this machine will be referred to herein as the instant machine. It is described in the patent to Las'ker 8: Mueller No. 2,323,816, and in the patent to John Mueller No. 2,381,361, August 7, 1945. It comprises 'a base "section having side frames 50, on which rest the side frames 5| of the head section. A power driven wormshaft 52, indicated by a dot-dash line, drives the main base shaft '53 by a worm wheel 54. The shaft 52 also, through miter gears '55, upright shaft 56, miter ears 51 and worm shaft 58, drives the worm wheels and '61, respectively, of a front head power shaft "62 and rear head power shaft 63.
An upward extension 64 of the shaft 56, also drives the paper feed machanism of the present the eccentric 65, which reciprocates the sensing pin box 84, is at its upper dead center.
Punched cards are fed by a picker 66 (Figs. 1 and 14) and feed rolls 6'! from a hopper 68 into a sensing chamber 10, and thence by feed rolls II into a receptacle I2. The picker is reciprocated by a cam I3 on the base shaft 53, through a follower I4, arm 15, link 16, arm TI, spring 18, i The cards are shaft 80, arm BI and link82. sensed by sensing pins 83 in a reciprocating pin box 84, and such of said pins as find holes, push upward set pins 85, whose motion is communicated by Bowden wires 86 in a translator 81, to code or permutation bars 88, which control a set of stops 90. In each denomination the stops 90 arrest a bracket 9| on a differential type bar 92, which slides on guide rods 93 and carries a set of numeric and alphabetic types 94. Said type bars are pushed up by springs and are restored by a restoring bar 95. Hammers 96 drive the types against the paper on the platen 97, mounted in the carriage I00. All of the mechanism above briefly mentioned is the same as is described in the Patent No. 2,323,816 and in the Mueller Patent No. 2,381,361.
The paper carriage I of the Powers machine, comprises a main bar IOI (Fig. 2), having secured thereto rails I02, grooved to slide on a fixed rail bar I03, which is mounted at its ends on a left hand frame bracket I04 (Fig. 6) of the usual kind, and a right hand frame bracket I05 (Fig. 3) here constituting a portion of the framing of the long feed mechanism.
Framing Most of the driving mechanism of the long feed, is contained in a detachable unit, a plan View of whose frame is shown in Fig. 24 where it is viewed from the rear of the machine. See also Figs. 2 and 3. The casting I05 is the right hand frame-piece, and another casting I 06 is the left hand frame-piece. The piece I05 has a front portion I 05I to which the carriage rail I03 is secured by a screw I051, and from which the vertical web extends rightward at I052 and thence rearward, to form the main portion of the frame piece. Said piece also has a projecting vertical wall I053 (Fig. 6)., which supports the worm shaft 64, as will presently appear. The member I06 has a vertical web with the usual bosses, and a forward projection I66I (Fig. 2) secured to the rail I 03 by a screw I062. At their bottom portions, the castings I 05, I06 have, respectively, horizontal walls I054 and I064 which overlap and are secured rigidly together by bolts I065. This frame may be removed from the machine as a unit, by removing the screws I058, I05! and I062.
The driving gear train The driving gearing of the paper feed, comprises a worm II6 (Fig.6) on an upper section of the shaft 64, which is journaled in blocks III bolted to the vertical wall portion I053 of casting I05. Said worm drives a worm wheel II2 (Figs. 1, 7. and 10) which has a bearing on a stub shaft II3 secured by a nut to a bracket II4 (Fig.
24) fastened by screws to the blocks III. The worm wheel II2 makes one turn per machine cycle, and it drives, directly or indirectly, three shafts, viz. the main paper feed shaft II5, the main cam shaft I I6 and a counter-shaft I I1 (Figs. 7 and 10). The counter-shaft II'I makes one rotation per machine cycle and the main shaft H5 in somewhat less than a machine cycle. These velocities may be obtained by any suitable gearing; but in the particular instance illustrated, they are produced by a rather roundabout arrangement, adopted here for certain technical reasons. The main shaft I I5 is journaled in the frame-pieces I05 and I06 co-axially with the stub-shaft II3, whose end is adjacent to that of the main shaft. A sleeve I I8 journaled on the two shafts, is rotatably coupled to the worm wheel II2 by a pin I20, and at its other end carries fast thereon a gear I2I, meshing with a gear I22 fast on a sleeve I23 which is journaled in the frame piece. I 05 and in which the right hand end of the cam shaft I I6 is journaled. The sleeve I23 is free on the shaft I I6. Inside the frame I05, said sleeve carries a gear I24, meshing with a gear I25 fast on the main feed shaft II5. These two gears have, in the present instance, a ratio of six to five, so that the shaft I I5 makes a rotation of 300 of machine cycle.
The cam shaft II 6 is driven through the counter-shaft II I. The latter has bearings in the frame-pieces I05 and I06, and also in a block I26 fast on the frame bracket II4. It is driven by a pair of gears I 21 and I28, fast, respectively, on the worm wheel H2 and the shaft I I1. Said shaft has thereon a gear I30, meshing with a gear I3I which has riveted thereto another gear I32, the ears I3I and I32 being free. on the shaft H5 and differing slightly in size. The gear I32 meshes with a gear I33, keyed on the cam shaft H6. The gear-pair I3I,. I32, stands between a collar I34 pinned to the shaft H5, and a collar I35 secured to said shaft by a set screw. The shafts II5 and .6 are timed shafts and it is important that they occupy, initially, fairly exact relative angular positions, and, as it is difficult to secure such exact positions by tightening a set screw, the form of gearing described, greatly facilitates the required initial adjustment. The gears I30 and I3I therefore have 36 teeth each, and the gears I32 and I33, 39 teeth each, of the same pitch. In assembling the mechanism, the shafts II 5 and H6 are first adjusted exactly to their correct relative positions with the gear pair I3 I, I 32 out of mesh. Said pair is then slid along the shaft II5 into mesh. The teeth will probably collide on the first trial, but by turning the pairs of gears slightly, an angular position will be found where they slide into mesh easily. They are then secured by tightening the set screw in the collar I35. Keyed on the shaft II5 (Fig. 1 0) is the long hub I36 of a five-notched clutch disk I31; and journaled on the left end of said hub is a drive disk I40 which (Figs. 7, 11 and 12) carries the co-operating clutch pawl I4I. This disk is normally at rest in an angular position determined by a detent consisting of an arm I42 (Fig. 2) carrying a roller I43, spring pressed into a notch in the disk; and whenever a long feed of the paper is required, the clutch pawl I 4| is caused to engage the disk I31 and impart one rotation to the disk I40. The projecting left hand end of the shaft II5 carries a sleeve I44 (Fig. 10) held on by a nut I45, which sleeve is in effect a part of 1 1 3 h f "Loose on said'shaft (or on said sleeve) is a unit herein called the drum, designated generally I46. It is built up of a hub or sleeve I41 having keyed thereon several notched disks I48, I50, II and I52, a gear wheel I53 and certain other devices to ,be mentioned hereinafter. By means to be described, a rotation of disk I40 imparts differential extents of rotation to this drum. The gear I53 meshes with a gear I54 (Fig. 7) on a horizontal-shaft I55 which, by miter gears I56, inclined shaft I51, and miter gears I58, rotates the shaft I60 of the paper cylinder .or platen 91. Vice versa, any rotation of the platen, as by hand or other means, is communicated to the drum I46. The miter gears I56 and I58 and the shaft I51 are covered respectively by housings I56I, I58I, and I51I (Fig. 6). In the instant apparatus the cylinder 91 and its pressure rolls are the means that immediately propel the paper, though it is now more common, in these machines, to do that by more accurate sprocketlike devices, also geared to the drum I46, the cylinder 91 acting merely as a platen.
The drum I46 is removable .and replaceable by merely sliding it off of or onto the shaft 5, it being retained in position by a latch IBI (Figs. 6and pivoted to the gear I53 and engaging in an annular groove I62 in the shaft. The gear I54 is not mounted directly .on the shaft I55, but
is mounted fast on a sleeve or hollow shaft I63 (Fig. 10) which has a bearing in the frame casting I06. The shaft I55 is polygonal in cross section and passes through a polygonal axial open.- ing in the sleeve I63, whereby the sleeve is in effect splined on the shaft, so that the latter can be slid lengthwise throughthe sleeve. Said shaft at its right hand end is journaled in a bracket I64 (Fig. 6) which is secured to the main bar IOI of the carriage. Theconstruction is such that the. carriage may be slid lengthwise to different positions onits fixed rail I03, and the shaft will slide with it, moving through the sleeve I63 without affecting its geared connection with the drum gear I53.
The gear ratio between the gears I53 and I54 is usually made such that one complete rotation of the former feeds the paper the length of a form. In a common case, the gearing is adapted to forms of a length of eight and one half inches, or 51 single line spaces. One rotation of the platen of the Powers machine feeds the paper 30 spaces, and the gears I53 and I54 are accordingly made in the ratio of 51 to 30. If the gear I 53 was made with 51 teeth and the gear I54 with 30 teeth, then each tooth of the gear I53 would correspond to a line on the paper.
In Fig. 10, three spur gears of different diameters are shown mounted on the sleeve or hollow shaft I63, of which the smallest is gear I54, which is of a diameter to feed the paper 51.single spaces to one revolution of the drum I46, the second gear, I54I, is of a diameter to mesh with a gear on the drum smaller than the gear I53, so as to afford a 1:1 ratio between the drum and the shaft I63. This would feed the paper 30 spaces per revolution of the drum. The
third wheel I542 would similarly afford a feed of 21 spaces per drum revolution, and, therefore, be suitable for forms of that length. The illustrated arrangement would be adapted for a customer who used forms of the three difierent lengths mentioned. The drum for the 30 line (five inch) forms would have its gear mounted on the drum in the plane of the gear I54I; and the drum for the 21 line (three and one half inch) forms would have its gear in the plane of the gear I542.
The line finding drum and its drive pawls space 6 on the paper, (Fig. 26) the first item on' line I4, and the total at the bottom of the form' on line 42, then one of the disks would have'a notch to bring the paper to line 6, another disk would have its notch arranged behind the first an angular distance equal to eight fifty firsts of its circumference, to bring the paper to the first item line I4 and a third disk would have a notch spaced 36 tooth spaces behind the first, to bring the paper to the bottom line, line 42.. This ar-' rangement will be understood from the following description. In general, a drum is made up of the required number of line finding disks, whichin the process of assembling, are turned to bring their notches into the relative angular positions required by the work in hand, and the whole is secured rigidly together by rivets I59 (Fig. 10) passing through the disks and through a flange on the sleeve I41.
The means whereby the disk I40, when rotated, drives the drum I46, including the gear I53, will now be described. Said disk has several posts or studs projecting from its face over the disks NIB-I52 of said drum. On the stud I65 there are pivoted four pairs of pawls, I66 and I61, one pair in the plane of each of said disks; each pawl being drawn toward its disk by ,a spring I68. In Fig. 2 the proximate pair are broken away to show the pair behind them. On a stud I10 there are pivoted spring pressed latches I1I, one normally engaging each of the pawls I66 to hold the latter out of engagement with its disk. In each pair a stud I12 on pawl I66 holds the pawll61 out of engagement until the former itself moves in. The pawl I66 has its tooth I13 abrupt on its advancing edge, topush the disk around, and the pawl I61 has its tooth I14 abrupt on its opposite edge to prevent overthrow of the disk when the pawls are arrested. In operation, a long feed is initiated by tripping one of the pawls Ill and closing the clutch. Usually, the notch is not in the stop position shown in Fig. 2, but may be anywhere in the circumference of the disk. The pawl teeth I13 and I14 will then ride idly on the surface of the disk until they reach and snap into the notch. They will then turn the drum the balance of a rotation, always arresting it in the position shown. When any notch is in that stop position, the paper is in the line space position for which that notch was set in making up the drum.
The pawls I1I aretripped by several tripping levers I15, one for each such pawl, said levers pivoted on a fixed stud I16, (Figs. 11 and 12) and rocked to normal position by springs I18. Each tripping lever has a stud I18 which, when the lever is fully operated, rocks the associated latch I1I to release the line pawl I66.
The tripping levers I15 may be operated selectively at times appropriate to the Work in hand and by means depending on the machine to which the invention is applied. One may be operated before the printing of a total in order to print the total at the bottom .of a form, or just after total printing in order to feed the paper to the next form, or after printing on the last line of the form, or, when desired, after the sensing of a control hole in a card; or'at other times, as required. The mechanism is thus readily adaptable to a variety of situationsand of uses.
The mechanism thus fardescribed is, in principle, sustantially the same as that described and claimed in the prior application for Letters Patentfiled February 17, 1944, by John Mueller and Joseph M. McDonnell, Serial No. 522,720, which issued April 26, 949 as Patent No. 2,468,341, though it differs somewhat in detail and design.
Means to operate the tripping levers and clutch The means to control the tripping levers I 15 and the clutch are of novel and improved construction. Said levers have three positions. They stand normally as shown in Fig. 2 and in full lines in Fig. 11. To initiate a long feed, the selected one of them is first set that is to say, it is rocked to the broken line position of Fig. 11, after which, at the propertime in thecycle, it is swung further to its effective tripping position shown in Fig. 12; and at the same time it trips the clutch to start the feeding operation. The clutch pawl I II is normally held away from the disk I31 in the usual way by a lever or clutch dog I80 (Fig. 11) pivoted on a fixed stud I8I and having a spring I82. Said dog or pawl has a post I83 projecting across all of the tripping levers I15. Each of said levers has a curved arm I84 with an abrupt end edge I85. A universal operating bar I86 extends across the rear of the row of tripping levers, said bar being carried by an arm I81 fast on a rock shaft I88 journaled in the frame casting I06. Inside said casting, the rock shaft has an arm I90 carrying a follower roller I9I controlled (Fig. 3) by a cam I92 on the cam shaft H6, and by a spring I93. During the major part of a machine cycle, the bar I86 stands as shown in Fig. 2, but in the mid part of each cycle, it is oscillated clockwise and back moving over the tops of the arms I84. of the unset tripping levers. When, however, one of said levers hts been set, the bar I86 will contact the edge I85 of that lever, and swing the lever to its effective position shown in Fig. 12, the stud I19 on the lever then tripping the associate latch Ill and freeing the associate drive pawl I66 for operation. When the tripping lever I15 moves to its dotted line position of Fig. 11, its curved arm I84 encounters or approaches the post I83 on the clutch dog I80; and when said lever receives its final movement from the bar I86, this arm I84 rocks the lever I80 to trip the clutch. It will be seen that the clutch is tripped by the tripping lever I15, and will not be operated unless one of said levers is set. Also, that any tripping lever may be set at any time while the bar I86 is at rest, and then, at the proper instant in the machine cycle, the line-finding pawl will be released and the clutch tripped by the action of the tripping bar I 86. When the bar I86 swings forward, it moves over the arms I84 of un-set tripping levers and prevents them from being set at that time. A prolongation of the bar I86 normally lies just beneath an arm I94 of the clutch dog I80 (Figs. 2 and 11) and positively prevents the tripping of the clutch when said bar is in its normal position.
The mechanism above described for tripping the feed pawls and the clutch, is an improvement over that described in the prior application Serial No. 522,720.
Restoring the drive pawls In order to restore the drive pawls I66 and I61 after anoperation thereof, a rock shaft. I (Figs. 2 and 25) journaled in the frame casting I06, has, justoutside said casting, an arm I96 from which a post I 91 (Fig. 25) projects and stands in front of the upright arms of all of the pawls I66. At the proper time in the cycle, this arm and post are rocked clockwise by a cam I98 (Fig. 3) on the cam shaft II6, acting on a follower roller 200 on an arm 20I fast on the shaft I95 inside the casting I06.
Means to set the tripping levers The tripping levers I15 may be set by a variety of means depending on the machine to which the mechanism is applied and on the particular job to be done. Several such means will be described herein. As shown inFigs. 2 and. 6,. four rockshafts herein called "tripping shafts, 202, 203,
204,, and 205, arranged in a vertical tier, have each an arm 206 to which is pivoted a push rod- 201 whose upper end lies beneath an ear formed off from an arm of one of the tripping levers, so
arm 2I2 on one of three transverse rock-shafts 2I3 pivoted in brackets 2I4 at the back of the tabulating machine. Each of said shafts has an arm 2I5 connected by a link 2I6 with a lever 2|! pivoted on a post 2I8 in a. guide bracket 220. The three levers 2 I1 are of different lengths and, each of them has an ear in position to be operated in a well known manner by oneofthe Bowden wires 86 in the translator 81. When a card having a control hole is sensed, the appropriate lever 2" is rocked, rocking the associate shaft 203, 204 or 205. In the Powers machine the Bowden wires and, therefore, the train of connections just described are set near the end of a cycle and are locked in set position until near the end of the next cycle, so that the tripping lever I15 will be retained in the position shown by broken lines in Fig. 11, until operated by the bar I86.
In order to make the mechanism flexible in its applications the arms 206 may preferably be operatively disconnectable from their shafts. The disabling devices used for this and similar purposes, as shown in the drawing, are of a familiar type. The hub of arm 206 is loose on its shaft, and lying beside said arm is another arm 22I whose hub is fast on the shaft. Said arm 22I (Figs. 13 and 28) carries a housing in which is a spring-pressed plunger 222, the stem of which has a finger button 223. When this plunger occupies its inner position, its inner end engages in a hole in the arm 206 and locks said arm 206 to the arm 22I and renders the former operable. To disable the arm 206, the plunger is retracted and turned so that a stud or tooth 224 thereon rests on top of the housin and prevents the plunger from entering the hole in the am 206. A number of these disabling devices are used in the mechanism, and for brevity they will be called herein dis! one associated with the disk I50 (Fig. occurs at about 330 of said preceding cycle. The
abling buttons. In setting up the mechanism for a particular job, any one of the four tripping shafts may be rendered incapable of initiating a long feed of the paper by setting its plunger 222 in its withdrawn position.
Operation of the feed mechanism It may be advisable at this point to describe in detail the mode of operation of themechanism as thus far described. For example in the form shown in Fig. 26, two or more lines of heading are printed, beginning at line 6 .of the 51-line form,'each line, of course, being printed in one cycle. The card for printing the last heading line has a control hole in order to cause the paper to be fed from there to line I4. This card is sensed in the latter half of the cycle preceding the one in which the last heading line is printed, the control hole causing Bowden wire 2 I9 (Fig. 6) to thrust upward the plunger 220 located on the translator, rocking thefrontmost one of the three levers. 2I1, and the upper one of the rock shafts 2I3. The latter, through its link 2I I, rocks the tripping shaft 203, which, through its Dushrod 201, sets the second one of the tripping levers I as shown in broken lines in Fig. 11 viz., the This Bowden wire 2I9 remains in its raised position until near the end of the last heading cycle. Printing occurs at about 165 of cycle. The universal tripper frame I86-, I81, starts to advance at about 126 and reaches its fully operated position shown in Fig. 12 at about 176. In that advance movement, the arm I15 trips the latch I1 I and releases thesecond one of the four feed pawls I66, which'falls onto the line-finding disk I50. This disk has its notch I50I so disposed that'when it is turned to the position of the notch I52I in .Fig. 2, line I4 of the form is at the printing line.
The tripping lever I15, in advancing to its fully operated position also acts on the post I83 (Figs. 11 and 12) to trip the'clutch dog I80, and close the clutch. A notch of the clutch disk I31 picks upthe pawl MI and starts the disk I40 into rotation at about 186 of cycle. A rotation of said disk occupies 300 of cycle, endin at about 126 of'the following cycle. v.As the disk I40 rotates,
'the feed pawl I66 slides around the disk I50 until it drops into the notch I50I, whereupon it carries with it said disk and the gear I53, which, through 'the described train of gearing, feeds the paper to line I4. Meanwhile, at from about 196 to 226, the universal tripping frame I86, I81 has returned to its normal position. When, near the end of the cycle, the Bowden wire. 2I9 returns to normal, the train of linkage ending in the push rod 201 also returns, allowing the'trippingv lever I15 to return to normal.
Also, the restoring bar I91 operates, reaching its forward peak position at about 176. This was at near the time when the pawl I1I was tripped; but the restoring frame receded from its advanced position before the tripping frame I86, so that the pawl I66 was released. It will be noted that an operated pawl I66 is restored by the bar I91, not immediately after the completion of a revolution of the disk I40, but a few degrees of cycle later and just prior to the time when one of said 'pawls' I66 would be released for a new operation.
It will be seen that a tripping lever I15 may be set to its broken line position of Fig. 11 at any by merely withdrawing the disabling button 223' on shaft 203.
Moreover, he may have other'set's of cards in no way related to those above referred to and with which he uses another translator.
The timings given in the description and in the timing diagram, are approximate only, and
are only illustrative.
,C'apacity feed On the form shown in Fig. 26, it is not desired to print any item below line 40; and in case there are further items to be printed, the paper is fed to line I4 of the next form, skipping the heading. In the illustrated-mechanism, this is done by the line-finding disk I52, which is the one nearest the reader in Fig. 2 and most remote in Fig. '7 and which is rotated to the position shown in the former figure to feed the form tothe first item line.
A rock shaft 225, herein called the capacity shaft (Figs. 2, 3 and 5) is journaled in the frame castings I05 and I06, and it has-fast on its projecting left hand end a plate'or arm 226 (Fig. 2).
Inside the frame I06 said shaft has fixed thereon an arm '221, shown (mostly in broken lines) in Fig. 3, to which is anchored a spring 228 tending to rockthe shaft clockwise. Farther within the frame I06 (Fig. 5) said shaft has fixed thereon an arm 230 with a follower roller 23I for cooperation with a cam 232 on the cam shaft II6, which cam, when it acts, rocks the shaft 225 counterclockwise; Said shaft 225 and its arms normally stand in their counter-clockwise position where they "are retained, against the tension of the spring 228, by a stepped latching member 233 (Fig. 2) engaginga corner of the arm 226.
When the latch 233 is swung downwardabout its pivot post 234, the spring 228 turns the shaft 225 a short distance clockwise until the corner of the plate-arm 226 is caught in a second notch 235 of the latch member and also swinging the follower roller 23I down onto its cam 232. When the shaft 225 rocks clock-wise a nose 236 mounted on the arm 226, acting on a post 231 projecting from the particular tripping lever I15 shown in Fig. 2, sets said tripping lever; that is to say, it swings said lever to the intermediate or set position hereinbefore described, thus preparing for a paper feeding operation by the line-finding disk I52.
The latch 233 is tripped by a cam or arm 240, consisting of a ring of sheet metal'mounted in the drum I46 and inthe position indicated in Fig. 10; and this -ring-has a projecting arm which revolves with the drum. It is indicated in dot and dash lines in Fig. 2 in the position it occupies when the paper is at the capacity line (line 40 in Fig. 16) of the form. When the paper is line spaced to the over-capacity line 42, the arm 240 trips the latch 233 by acting on a finger 24I on said latch. In order to permit reverse rotation of the drum'l46, including the arm 240, said finger is pivoted to the'latch and controlled by a spring 242 anchored to said finger and to the arm 226.
' Said spring presses an arm of the finger against a limit stud 243 on the latch, and it also serves as '1 1 the spring to pull the latch member itself into engagement with the'arm 226. The construction is such that, if the drum is turned backwards, the finger will yield to the arm 246, turning about its pivot to let the arm pass.
The capacity feed mechanism, as thus far described, would operate as follows: The line space :and retained there by the latch 233. The mode of operation just describedis satisfactory in many instances. However, by other mechanism to be presently described, it is. modified in certain re- .spects so as to give better results in cases where total taking operations are involved.
The cam 232 (Fig. 5) has on it two restoring humps 232I and 2322, the former restoring shaft 225 at around 286 of cycle and the latter at about 102. Both of these humps act during the period between 214 of one cyc1e,-when the latch 233 is tripped, and 126 ofthe next cycle, when the universal frame I66 begins its advance to initiate the feeding of the paper. Referring to Fig. 2, the arm 240, when it operates on the finger 24I of the latch 233, only moves one line space, which, however, may be a single, double, or triple line space distance. Said arm has a blunt end of such dimensions that that amount of rotation of the arm will depress .thefinger but will not move clear past and free of the finger. The arm therefore holds the latch depressed until the long feed be- .gins, when it moves past said finger and allows the latter to return to engagement with thearm 226. The oscillations of this arm by the first passage of the humps 232I and 2322, therefore do not prevent the feed from taking place. After the feed starts the hump ;232I. will restore the parts On a long feed following a total, the paper is fed from someline of one form to a line of the next form,in the course of which the arm 240 would trip the latch 233 but would pass beyond it and immediately release it. The capacity shaft would thus be tripped, but would be effectually restored by the next hump on the cam 232, and no capacity feed would result.
In the specific formillustrated, the capacity feed disc I52 brings the paper to the first item line of a form, the same as does the disc I50 operated by the trip shaft 203 under card control. When such is the case the trip shaft 205 which also operates disc I52 can beutilized to feed the paper from the last heading line of a form to the first item line of the next form under card control, permitting the disc I50 to be used for some other purpose.
Total taking Some of the long paper feeding operations are associated in one way and another with the taking of totals, and before vdescribing those operations it is necessary to describe some of the mechanism of the Powers alpha and numeric (or No. 3) tabulator to which the long feed mechanism I is shown applied in the instance illustrated in the drawings.
acted on by the.
Each type bar 92 (Figs. 1 and 14) is controlled at times by a slam bail pawl" 245-which is itself controlled by a control bar '246, mounted for a short sliding motion front and back of the machine. There is a row of these pawls and bars clear across the whole series of type bars. In Fig. 14, the bar 246 is held frontward, and a spring 241 anchored thereto is pressing the pawl 245 into engagement'with the rack' teeth of the bar. In this position the pawl prevents rising of the bar but, if the bar were already in an upper position, the pawl would permit downward motion of it. The control bar is itself urged rearward by a spring 248, and if allowed to yield thereto, moves rearward until its rear end presses the pawl 245 out of engagement with the rack, (Fig. 1). Beneath the tier of control bars 246 arefour rock" shafts, viz., a grand total shaft 250, a total shaft I, a fslam bail shaft 252 and a designation shaft-253 Each of these has fast thereon an upwardly projecting blade 254, extending beneath all of the bars 246 and each sweeping toward 'the front of the machine when the shaft is rocked clock-wise in Fig. 1 4 (counterclockwise in Fig. 1). -Pivoted to each control bar are three connectors 255, 256 and 251, each settable into active and inactive positions. In the setting shown, the connectors 255; and 256 are inactive; but if connector 256, for example, was turned, clockwise in Fig, 1, itsheelwould come into the path of movement 'of the blade 254 on the rock shaft 25I Sa id slhaft"is rocked counterclockwise in Fig. 1 preparatory to andduring every total-printing ,cycle, and its blade would move the bar 246 f'rontward andlock that particulartype bar againstn'ising infltotal printing cycles. The connector 251 'hasa spring pressing a nose on its forward end into engagement withja differential detent 258 having three notches at different distancgsfrom its pivotgThis detent and connector are shown set so that the latter has its rear end in positiqn to be controlled by the slanrbail shaft 252, whi'ch'shaft is shown in its norm q$ i n-in.Eig. 1,.w the wl 24 ",out .of engagement, and in rocked or pulled ijposition. in Fig. 14, where it has moved the pawl into engagement to prevent the type bar from .rising. The connector 251 can also be set to an inactive middle position and to a third position Where its hook-like frlont end is in position to be blade 254 of the designation ,ishaft-253r A .total taking amid unit zen (Fig. 15)
mountedqn top of. the right hand base frame 50, has two cam shafts, viz., a total shaft 26I and jagra'nd total shaft 26 2, each carrying certain I'cams which control functions of the machine in total taking operations. The total shaft 26I has ,a onerrevolutionmlutch through which, when closed the [shaft is geared to make one revolution 1 intwdcycles, viz.,ablank cycle and a total cycle. The'shaft 262 has a similar clutch and when the cycle, a total cycle and a grand total cycle. Figs.
latter is closed said shaft is geared to make .one revolution in three machine cycles, viz., a blank 14 and l'l show'the slanrbail cams 263 and 264 on the total and grand total shafts, respectively.
These cams have. follower rollers on follower bell crank 21I and link 212, to pull" (rock clockwise), the slain bail shaft 252. This linkage is connected through a short link 213 with an arm on shaft 253 to rock the latter shaft also. The
14 and all type bars used for printing alphabetic and other designatory matter are put under control'o'f the designation shaft 253 by setting their associate connectors 251 each with its front hooklike end in the path of the blade 254' on said designation shaft.
The type bars begin to rise at 33 of cycle, are at their highest points at before 158, and are fully restored by 283. When, therefore, the linkage 251213 is pulled early in a cycle, all of the type bars set up as just described, will be locked down by their slam bail pawls 245, and no printing from them will occur during that cycle. The cams 253 and 254 pull this mechanism earl in 'the blank cycle of a total taking operation and hold it pulled until late in the cycle, and pull it again a little before the middle of the total cycle so as to engage the pawls 245 with the bars while the latter are in elevated positions, so as to prevent slamming of the adding type bars when the totallzers are withdrawn from the racks. In grand total operations, this mechanism is pulled nearly throughout the blank cycle and in the lat ter part of the total cycle as before, and also is pulled again in the latter part of the grand total cycle.
In order to stop the feeding of cards during total taking, another pair of cams on the shafts 251 and 252, said cams not shown but shaped about the same as the cams 326 and 321 of Fig. 15, operate'a follower lever 215 (similar to lever 255) to push downward a link 216 (Figs. 8 and .14), which through hell crank 211, link 218 and arm 280 rocks a shaft 281 having thereon an arm 282 in the form of a hook or latch, adapted to engage a shoulder of the link 15 and prevent ad- Vance of the card picker 55. In Fig. 14 the parts are shown operated as just described. The sensing chamber for the cards, is closed by the card stop 283 shown closed in Fig. 14. It is moved up to release the card by arms Q8 on a rock shaft 285 which is oscillated by'a certain cam on the base drive shaft 53, which cam, in this machine holds the stop 283 open only from about 130 to about 200 of cycle. In order to lock the card stop against opening at that time, an arm 285 on the shaft 285, has a lug .281 lying just behind the link 215 so as, when said link is in its depressed position shown in Fig. 14, to lock the shaft against turning counter-clockwise and opening the card stop. The link 216 is cut away on its rear edge at 288, so that; when the link isin its normal upper position, the stop is free :to open under control of its regular timed cam.
A blank cycle of the instant machine'is one in which the-card in the sensing chamber, stays there, no card is fed from the hopper 58, and the type bars do not rise to print. It will be seen from the foregoing description, that such a cycle may be produced by rocking the two levers 255 and 215 as shown in Figs. 8 and 14; and it is in that way that the blank cycle of a total taking operation is brought about. It may be remarked that in the instant machine, the lever 215 is rocked to its operated position early in the blank :01? the two or three cycles of a total or grand total operation.
The total shaft 251 (Fig. 16) is pulled (rocked clockwise) in the latter part of the blank cycle and held pulled until the latter part of the total cycle, by one or the other of the total cams 291 or 290, having follower lever 289 or 292. Said follower lever 29,2 operates link 293, lever 294, link 295, bell crank 295 and link 291 the last pivoted to an arm 298 on said shaft 251. On grand total operations, the follower 289 operates follower 292. The bell crank 295 also operates a link 300, bell crank 301, link 302 and arm 303,
to rock a shaft 304 which is a part of the line space mechanism of the instant machine. This linkage also operates other devices not shown, but which contribute to total taking.
The grand total shaft 250 (Fig. 18) is pulled by a cam 305 on the grand total cam shaft through its follower lever 305, lever 301, link 308, lever 310, link 311, bell crank 312 and link 313, the latter pivoted to an arm on said shaft 250. The bell crank 312 also operates a link 314 which rocks the same bell crank 301 as the total pull linkage, raising the link 302 to rock the shaft 304.
This link train also includes other parts not shown.
' Line space mechanism The line space ratchet wheel has been removed from its usual place on the platen shaft and replaced by a ratchet 901 on the hollow shaft 153 in the long feed unit (Fig. 3), which shaft drives 'the shaft 155 which is geared to the platen.
' to an arm 9 on said'shaft and operated by the shaft 53.
follower lever 912 of a cam 913 on the drive Said cam is timed to rock the lever 904 counter-clockwise in Fig. 3 to draw the pawl 902 back to engage a fresh tooth of the ratchet at from to 156 of cycle. and to rock said lever clockwise to space the paper at from to 272 of cycle. The extent of line spacing, whether single,'double or triple, is regulated by the same means as heretofore for regulating the extent of counter-clockwise rotation of the shaft 908. Fig. 9 is a right hand side view of said means. An arm 914 on the right hand end of the shaft 908, has a pin 915 adapted to be variably arrested by a stepped stop plate 915, loose on the rock shaft 304 hereinbefore referred to and which is jour- 'naled in the frame member 105 (Fig. 5). A plate- I on the plate 915. By setting said pin in one or cycle and is held in that position until the end 5 another of said holes, the stop plate 915 can be 'set to permit an extent ofmotion of the pin 914 for triple, double or single spacing, or for no spacing. A third plate-like arm 922 can be adjusted by a plunger 923 in said arm and a series of holes 924 in the plate 918 to four different settings. When set in the end one of said holes, a'finger of the arm 922 is in contact with a fixed stop 925 and prevents counter-clockwise motion of the arm 922, the arm 818 and the shaft 304; but when set in one of the other holes it permits'such rotation, and rotation of the stop plate 915, to the extent of one, two or three steps of plate 915. Thus, if the latter plate be set as
