The present` invention relates method of making note sheets `forfmusical instru-u ments, more particularly note sheetsbearing markingscomprising informative indicia in addition to and co-related With note perforations.` @ne kind of marking commonly used on note sheets `is a more or less continuous line` or other indication known as a dynamic line,tlie purpose of which is to` indicate variations in the intensity of the playingofthe `notes i represented by the note perforations.

rlhe problem. of applyingV informative markings to note sheets has been approached from a number of angles, none of which has heretofore proven'so effective as the method forming .the subject matterof applicants present application which is a division,` of his Patent No. 1,432,424, granted October' 17, 1922, forl machinesfor use in the mannfacture of perforted note sheets. @ne object of applioants method` is Ato produce a note sheet or a plurality of similar note sheets in 7a snbstantially continuous .operation` and coincident with a single operative manipulation of `a so-called master or pattern sheet, although it is contemplated thatin certain respects, the invention includes the `making; of a note sheet or a plurality of similar note `sheets otherwise than coincident with a single operative `manipulation of a single master or pattern sheet, sheet` is employed Whichrembodies an instrumentality for controlling the making' of an informative marking on the note sheet and f also embodies a note perforation pattern,

`extent concurrently.

it is contemplated that'both the marking and the perforating may take place to certain` jects, in view, the improved method of the y present (applicati on contemplates the making of note sheets havingfnoteperforations `and informative indicia related` thereto in which a moving` y note sheetA is `subjected `to Va marking operation and then,` after a predeter- However1 Where a pattern A further object of` the invention is to apply the informative mined increment` of marking has been applied, the.` note perforations are made, `the marking and the perforatingthereafter being concurrent. `One formof apparatus by means of` which my improved method may be practiced is shown inthe drawing accompanying the present specification, it being understood that said` drarvingrepresents.

` The perforating mechanism andthe` pattern means for selectively controlling `the perforatinfr, and also `the feeding "mechanism for the note sheet material tov be perforated,

may be of any suitable type.` The illustra-` tive` embodiment comprises a pattern or stencil sheet 2` and note sheetnnaterial The pattern sheet isshown as provided with ,perfo'rationsfl corresponding to perforations intend-edto be punched in the note `sheet material 3 `which maycomprisea stack tillv` ofsuperposed sheetswhich maybe punched y collectively.

The pattern sheet 2 is mounted upon .a spool 8 and may be fed in any practicable manner andwound, if desired, :upon atakeup roll .which is considered unnecessary to befshoivn in the drawing,` For the purposes of `the specific machine it `isl desired that the feed ofthe pattern sheet2 be synchronized with the operation of the perforating` mecha- `msm and to illustratediagrammatically one Way Vin which this may be done, theI pattern sheet 2 is shownfas passing over a drum `9 which `,seared With or otherwise synchronized with the perforating mechanism` asthrough gears'lO, l0.` Thevdrum 9. is

provided with teeth 11,111, to engage uniformlyspaced perforations 12,.l2, in the marginofthe pattern sheet 2. The cooperation'of. these teeth l1 with the perforations l2 (for any equivalentfor substitutedjerpedient) may, insure predetermined successive relationships betvveen'the moving pattern sheet` andthe {perfor-ating mechanism and also the moving note sheet material.

The `pattern sheet 2 exemplifies a `prime e c controller of a )unch selecting mechanism Vwhich may be 'o any practicable type. One

suitable formof punch selecting mechanism comprises a tracker' bar 15 provided with vente Ato be opened by the perforations el ol the pattern sheet. Each vent is connected by a duct-exemplified. by the duct 16 with the controlling valves ont'` a power Y pneuinaticl. As well understood in `the art, when the corresponding vent in .the tracker bar 4is opened by Va perforation inthe pattern sheet, suctionis admitted to the power pneumatic 18causing the latter 4to `collapse. y AWhen thuscollapsed thelpneumatic `18 lifts" a selectorslide L20; but when the tracker vent is `again closed, permitting the pneumatic 18 to expand again, the slide 2O is drawn downwardly to the position shown in .the drawing by n. spring2l.

i It Will be understoodithat there is a series of selector slides 20 corresponding each `to one of the punches of :thelperforating mechansmf One complete set of selectingand punching devices is shown diagrammatically 4in the drawing; and it will ihe understood that `these partsare reduplicated as many c timesfas -niay .be necessary .to provide for punching the desired number of rows of per- -forations. y i

Theiselecting mechanism comprises further a "horizontally reciprocating cross head 22 `cai-.frying selector pins 23 which Vare so mounted toslide lengthwise readily in the cross head 22` sThis cross head 22 is connected by a link 25 with an eccentric upon the shaft `26 which shaft `is rotated continuously during `the operation of the nected parts 83, 34..

rests 1in a. guide `Way in, avertically recip-` rooatingcross head comprising thetwo conllhe part 134 carries a `gang of `punches y35 and the' part 33 includes the punch driving bar 36.

The cross fhead, 34 is reciprocated Vvertically in appropriate guide `Ways lby aneccentricjiupon :the shaft i26,.which` is unnec-` essary to'lbe shown. `'This suffices toillustrate that'. foreach"completerevolution of the shaft 26, `the cross head 33, 341is moved dmvnwardly and then 'upwardly through one complete rcciprocation.' The punches 35 are carried sniciently loosely inthe cross head piece 34 to permit them to `drop against the note sheet material Bwithout perforating the saine `except when the selector bar 32 has been moved far enough 4toward .the right in the drawing so that the full Width will be interposed between ,the driving bar 36 and a punch head, otherwise the punch may rise into the .notched end 32 and does "not perfor-ate the sheet materia-l. i c

The punches 35 are arranged to slide vertically'in a stripper `bar 88 `which overlies the note sheet :material 3 supported `at the punching point uponadie B9. n

With the describedarrangement, .When the cross `head 22 is moved toward tihelfleit in the drawing, thelever 28 is permitted Ato rock `slightly contra-clockwise and thereby to move the selectorzbar 32 toward the right. I1'` theselector slide 20 remains in the position shown,4 the movement ofthe selector pin `23 is arrested `insnch a position that the selector bar 32 cannot move far enough to be interposed sin driving position Abetween the punch 35i-and the drivingbar 36; but if the selector slide 2O has ebeen lifted (bythe openingot' the corresponding tracker vent) the cut-out portion 40 of the selector slide is thereby positioned opposite the selector pin 23, permitting a sullicient movement of the pin, lthe lever 28 and selector `bar 32, `to move the latter `into driving typosition and cause its corresponding `punch to be driven through the `note sheet material 3. As will be understood by those skilled in .the art, the lhorizontal reciprocation of -the selector cross 'head 22, andthe vertical `reciprocation of the punch erossihead 33,84, are relatively so timed that .the .cross ihead 22 is moved toward the left to position the various selector bars A32 appropriately to the `perfora- `tions to be punched, preparatory `to the descent of lthe cross head 83, 34 `to drive the selected punches through 'the note sheet `material.` `It `is to be understood :that Athe punch selecting and lperorating mechanisms :just described `are merelyilllustrative and any suitable equivalent `or `substitute may be employed y The `note sheet material 3 may `be fed relatively tothe punching mechanism in any practicable manner. For instance, cooperating endless belts or ehainsll, 52 may beprovided having cross bars 5B, 54 so disposed `that a cross 'bar 53 andacross bar 54 registerwith each other on opposite sides of the note sheet material 3 on the adjacent runs of the belts or chains, so asto gri c `,the note sheet material ibetween the cross rs with ,suflicient pressure to cause the note sheet material. to accompany :the belts `r11-chains .during their movement. As this feed mecha# insmis diagrammed 1n the drawings, the

sheet A` meets the sheet B so that the two (together with others if desired) may be fed collectively to the punching point. The sheet B passes around- idlers 85, 86, 87 and "88 corresponding to the described idlers for the sheetA. The idlers 85 and 87 are adjustable in their bearings.

It is assumed that the dynamic line is to beexactly thesame on both of` the sheets A and B and that upon each sheet the dynamic line is to bepositioned in a precise predeten mined relationship `with the perforations in the sheet. To suit i.these purposes it `is important to predetermine accurately a certain"length of note` sheet material `between the exact marking point and the punching f point.` 'In otherwords,if the length of the .Y sheet A between its marking device and the `shown as provided with horizontally slotted Y punches were greater than the length of the sheet B between its marking device and the punches,ftlie dynamic line and perforations on the former when finished `would have a different relationship from that of the dynamic line and pei'torations upon the sheet i B whenv finished. `'lhereiore means exemplified by the provision for adjusting the idlers '77 and87,` is supplied for adjusting the lengths ofwthe sheets. y For example, if the roller 77 is adjustedtowardthe left in the drawing, a greater length of note sheetis thereby caused tointervene` between the roller 77 Vand vthe punching point, and vice versa it' the roller is adjusted toward the The rollers 75, 77 85 and 87 are present their rear sides toward the punchesgf 4Hence the illustrative arrangement of the rollers 4.7 5, 76 and 77 serving to reverse the sheet to present its: face upwardly exposed to receive a marking pen. l

The sheet A is acted upon by amarking device 95 `which may be of any suitable type as for instance a `siphon pen. A similar marking device 96 is provided for the sheet` Y B and these may be duplicated for asmany other sheets as aredesiredto be marked concurrently. Each pen` is mounted upon a holder 98 which may be inthe form of a` sleeve pinned to a shaft mounted upon a horizontal axis in an arm 99 xed upon a vertically disposed shaft 100. Upon the same shaft is pinned anarm 'having at one c end aweight 101 andat its other end a lug 102.` The weight arm' and thepen holder 98 being pinned `to the same shaft, the weight tends to hold the `pen down against thel note sheet material and by depressing lug 102 thepen may belifted off `the sheet. Thepen or other marking device is thus provided with means forimoving it toward and from the sheet and this means may be appropri# ately operated auton'iatically. so as to make individual marks upon the sheet or to move `the pen onto the sheet and permit it to rest there to make a continuous line or a line interrupted as desired. y

-Fortlie purposes of the specic type of continuous dynamic line assumedto be desii-ed in the present instance, the means for moving the `marking device toward and from the sheetis automatically operated to i move the pen into marking position against the sheet at the time the dynamic line is desired to begin, and to` withdraw the pen from the sheet when the dynamic line has beenfinished.; i 1` i 'The `mechanism for this `purpose com-v prises a vertically disposed slide rod103 havingfingers 104, 104 respectively to cooperate `with the lugs 102 on the pen carrying shafts. The upper lend of the slide rod 103 is secured to the movable "board of a motor pneumatic `106 which through ap-` propriate valves is arranged to be exhausted upon the opening of a tracker `vent 107,1 a duct .108 connecting said vent107 with the valve mechanism for the` pneumatic `106. In the illustrative apparatus the vent 107 is arranged for cooperation with the same pattern sheet which constitutes. an element of the punch selecting mechanism but this `is not essential. In the specific apparatus the vent 107 is intended to be closed when the pattern sheet 2 isirst introduced and pre paratory to the beginning of the dynamic line, and to be opened at or justbefore the instant when `the dynamic lineis to be begun. The illustrative manner in which this is accomplished will be more fully described hereinafter.

The pen carrying rod is mountedbetween two rocker arms 110,` 111 mounted upon a common axis, the arm being pivot-ally supported upon a bracket 112 andH the arm 111 upon a bracket 113. As shown in Fig. 2, the arm 111 has a finger 115 connected to a` link 116 and also to a spring 117. As shown in Fig. 1, the link116 con# nects the finger with the movable board,

of a pneumatic 120. By collapsing the" pneumatic 120 more or less, the link 116 is moved toward `the left in Figs. 1 and Q, thereby rocking the finger 115 and arm 111 in a contra-clockwise direction to 'move `the pens transversely of the direction of feed of the note sheet material. 7When the pneu* matic 120 ispermit-ted to expand, the spring 117 rocks the finger 115 and arm' 111 in a clock-wise direction to move the pens in the Hoppositeidirection transversely to the direc-` tion of feed ot the note sheet material.

-Thus by varying the degree of exhaust in the pneumatic 120` the pensr may be oontrolled so that the result of their transverse l pneumatic '120 `witha cylinder 122. .Tlie

cylinder basa port128 to the atmosphere.. y

of 'the cut-away portion Whichmoiistitutes the dynamic line pattern. lWhen this occurs movemcnton the note sheet and the feeding movement of the note sheet shall produce the meandering dynamic line. The degree of exhaust in the pneumatic 120 `may `be varied in any practicable manner.

For example, a duct 121 connects the and also connectedV by a duct to an exhaust l chest l A luplex pieton havingI the `parts 126 and 12T has` alsnug but .sliding tit in cylinder 122 and the stem of said piston Vconnectedto alever 128` fulcrumed at 129, the lower end of which ispivoted at 130 to the link 11G. The cyl-` inder 122 is connected by, link 132 with an extension 133 ofthe "movable board of av pneumatic 134 and a part of the same eX- tension 133 on the o D osite side of the hinoe of the pneumatic 134, is connectedto slide 136 fitted in the tracker 15 and carrying a y l bleed and thereby permitting `the `pneumatic tracker vvent 138 connected by a chiot 189 with the interior of the pneumatic 184. The-A pneumatic 134 is arranged to be` exhausted l past ableed 140 through a duct 141 coni-` municating with the exhaust chest 125. ifi spring 142 tends to expand the pneumatic Tocoiitrol the operationof the described apparatus, the pattern sheet 2 or its equival lent or substitute is provided with means coi operating with the tracker vent 138and there-tlirough to governthe degree of ex haust inthe pneumaticg120 so as to move. the pens desired transversely ofthe di-V rection of travel of the note sheet.

fis one arrangement foroperating `on the l tracker vent `138`,the margin of the" pattern sheet 2 is cut along a meandering line cor! responding in shape to the meandering dy-- namic line desired to be-` marked upon the l note sheet.` In other Words the edge of the punch selecting pattern sheet may be `cut in the shape of a1 pattern to predetermine the undulations in the dynamic line...

Thefree end of the pattern sheet 2is preferablyleft of full width so that-when inijtially secured to the talieup roll, the advance end of thepattern .sheet will elosetheftraclier vent 107. Under these circumstances the `pneumatic in expanded position, the

slideurod 103 is held in its lowermost posi` tion by gravityvand therebythe pens are held away from the note sheet material,

At this time also the introduction of thef pattern sheet may have; closed the tracker l vent 188. The immediate" effect `of this is, to cut off atmosphere from the pneumatic 34 which, being then exhausted `past the bleed140, is collapsed.` But, in this collapsing movement it draws the slideV 136 towardthe leftin Fig.` 1 and presently the vent 138 is partially uncovered so that an atmospheric bleed is established to the pneupatternedge. 1f it were desired to employ freely flexible.

"matic 134. The collapsciof thepneumatic 134 will continue until this pneumatic bleed suffices to balance. tlie cXliaiist past` the bleed i ,140 whereupon thcpneumatic 134 willcome `to rest in a partly collapsedposition. l

Assuming that the foregoing has occurred `upon initiatintroduction of thefpattern sheet to the machine, the feed of the sheetrpresently carries tothe tracker thc` advance end the cutaway portion leaves open the )tracker vent107 which `producesa l collapse of the pneumatic T106 thereby lifting the slide rod l103'and.permitting the weights 101 tonmove` the pens down upon" the note Sheets and to" hold them there inmarlcing position. `At the saine time thevcut-away margin of thepattern sheet 2 opensthe tracker vent 138 and `disturbs the balance between the suction bleed and the atmospheric bleed to the pneumatic 134, by increasing the" atmospheric edge of the sheet 2 meandersacrosslthe .Vtracker l bar, the `described ,l arrangement ofl `bleeds so varies the degree of exhaust* inthe pneumatic 134 `thatits collapsing and` ex- 138 to follow accurately the `undulations `of that pattern edge ,t and in ,this manner 'those undulatioiis" cause the corresponding movement to take place in the extension" 133 of the movable board of the pneumatic `134. `Thus the cylinder 122 is` caused to recipro- -panding movements cause thetracler vent cate in an axial directionwith a motion exact-m 4 `ly corresl'iondingtothe Idegree of variation in `what may be called the Aamplitude (measured transversely of the pattern sheet 2) of the a pneumatic 134W of sufficient mechanical power "directly to movethe pens and the parts upon which tliey"1aie mounted, there mightbe a direct mechanical connection between the extension lyand the rocking support for the pensi It islpreferred, however,

to use a pneumatic 134 of low power `which Y shall be morereadily responsive tothe de `scribed arrangement of bleeds, and to use i incooperation therewith alworling neu- `inatic of-higher power and forthis the pneumatic is used. l

To permit freedom of, movementl ofthe cylinder 122, the ductsz121 and124 are made purpose i 41n the position shown in Fig. ltheduplexf piston 126,127 is so positioned inthe cylinder 122 that bothl the "atmosphere port 123 and the exhaust Aport 124 are closed." If

under these conditions, the pneumatic 1134 collapse slightly,`the cylinder 122 Will be moved toward the right and thereby, While i the atmosphere port 1.23 is still held closed,

the exhaust port 121.1L will `be open atleast to a slightextent. Thereby the pneumatic 120 vvillbe exhausted to some extent and will collapse. This `collapsing movement rocks the lever 128 clockwise `and moves the piston 126, `127 toward the right causing it` to follow *the-movement ofthe cylinder. "This movement of tliepiston tends to closethe exhaust f port 124: and 'does in fact close it if thedescribed collapse ofthe pneumatic 134 ceases.

"-Infact,thepiston 126, 127 follows the move- -`ment lof lthe"=c`ylinder `122` until' finally the piston resumes the `position` shown" in *the 'drawing closing both 'the 4atmosphere and the exhaust ports of the cylinder. g There- V"il 1--"n`iatic 12() is held constant temporarily `until pon the degree of derhaust in the pneusome further movement ofthe cylinder 122 *takesplace Elf then -theipneumatic 134 expende" fsomeivhat,moving the cylinder 122 tovvard'thelleft, *the atmosphere port 123 is opened, the pneumatic 120 is permitted to -eipiand, and the `lever 128 again rocked,

With `the illustrative `arraynpernent shown `iin .'Fig. 1, lthe .amplitude vof undulations of :the pattern "edge ofthe sheet 2 produces onA the note sheet a somewhat greater amplitude of `undulations ini the dynamic line' measured `,transverselyofthe noteisheet. i The slide 136 Y and the link 132 are connectedto the lever` .aprovidedxupon .the movable `hoard of the pneumatic 134, at substantially equal vdisi itan'ces fromthe hinge of the pneumatic con- `stitut-img the lever-s fnlcrumtherefore the extent of ,movement "of the slide 136 i (which .-cXactly .tollovvs i the amplitude.` of the pattern undulations), produces an equal extent of movement of the link132 and cylinder 122. The `effective moveincntof the piston 126, 127 is the same as that of the cylinder 122; and the extent ofthis movement oi' the piston produces an equal `extent of movement oi the link 116, because, asY shown` the fulcrum of the lever 128 is located midway hctweenthe respective points of attachment of. l

the piston and the link '116; Therefore the extent ot movenientof the link 11,6 is to `all intents andpurposes equal to the amplitude of the undulat-ions in the pattern margin. Thus theoscillations of the `finger 1.15 (sce Fig. 2) are equal in extentto the amplitude of undulations of the pattern edge but, as shown, the distance of the pen point `from the fulcrumld upon which it rocks in its `transverse movement, is greater than the distance `from that fulcrum 10() to the point ot' attachment `of the link `116. and therefore the extent of movement oli the `pen is greater thanthe extent of `movenicnt of the tracker vent slide 136. In other Words the amplitude of undulations of the dynamic line on the note sheetis greaterthanthat ot rthe pattern edge.

Thus the variations in Vamplitude of the dynamic line are made to correspond exactly With the variations in the pattern educ, hut tlieamplitudes themselves are greater in `the tirst case `than inthe last. `In other YWords, the meandering of the dynamic lincon ihc note sheet covers a Wider area than the meanderings ofthepattern edge on the pat-` tern sheet;` It' desired, however, the relation between the amplitudes of pattern edge unlil `dulations and dynamic line undula'tions may be adjusted by `moving;r the 'fulcruni 129 o'f `theflever 128. For instance, if the fnlcrum `129 is moveddownwardly (in the slot of the lever 128 provided to permit that adinetinent) the amplitude of undulations of the dynamic line is diminished and may he Iliade equal to those of the pattern edge, or other- Wise-varied as desired.

As' will appear to those skilled in the art, the `pattern edge on the sheet 2 is merely the illustrative `form of prime controller 4for markingdevices, andit may ormny not be used in `conjunctionvvitha prime controller, suoli as the patternsheet 2, forpunch selecting mechanismor the like. The specific pattern sheet 2 however,` serves as a, unitary prime controller for boththc 'punch selecting mechanism andV the marking mechanism;

"and is particularly adapted to provide for marking thenote sheet material before it is perforated.

In the usual `nished notesheet it is im-` portant that 'each point in the dynamielinc be positioned ilengthwise `the "sheet in a definite relation to the note-playing perforations. Forinstance, it is ordinarily desired that `any given group of note perforations shall reach the tracker i at `approximately the same time thatthosepartsfot the `dynamic line port-anungy to those noto pei-torations occupy the eld ot vision: ot the op` erator. i y i For convenience iimlescription it maybe assumed that the advance end oi a dynamic i line to be marked by the apparatus ot the dravvinp` is desired to be placed in the saine; line transverse the `note sheet, :nth the ath Vance end of the initial note pm'toration for illustration.

therein. But as already described, after the advance end ot the dynamic line hasbeen marked on the note sheet material* the latter obliged to travel trom the pens 95, 96 through a substantial distance to the punches before the note sheets are presented in position to receive note pertorations aligned with the advance end ot the dynamic line. To suit this situation, the illustrative ap paratus is so organized that the marking; of

end i ot the pattern edge and the `advanceend 161 et the iii-st note perforation will depend largely uponthe relative speeds ot feeding movement ot the pattern sheet 2- and the note sheet inaterlal-thedesideratum lieing merely that during the timethe pat-tern sheet 2 is t'cd through the distance between the points lo() and itil, the note sheetmaterlal Wil have been ted throughthe dis tance between tlieinarkinn point and t-he punching1 point. l

Thusj it will appear' 'from the foregoing that Inv im )roven method ma be `aracticed i in connection with a marking mechanisi and a pertorating mechanism, so co-ordin'ated as to produce note sheets having note pertorations and informative markingslocated thereon in predetermined relationship; and this cti-ordination ot the tvvo mechanisms may `be governed by a single prime controller such the pattern sheet 2, although this isnot indispensable.
