PERFORATING-MACHINE.

Patented Dec. 28', 1909.

Application filed March 16, 1907. Serial No. 362,655.

To all whom it may concern:

Be it. yknown thatILEUGENE DE KLnisT, a citizen of the United States, residing at North Tonawanda, in the county of Niagara and State of New Yorlnhave invented a new and useful Improvementin Perforating- Machines, of which the following is a specication.

This invention relates more particularly to machines employed for perforating the music sheets used in connection with automatic musical instruments.4

In machines of this kind as ordinarily constructed, the web or blank music sheet passes between 4feed rollers which are ro tated intermittently at a` constant speed, thus advancing the sheet by uniform steps from its front to its rear end and spacing the perforations with corresponding uniformity. When the music sheet is placed in the musical instrument and its frontend attached. to the take-up roll in the customary manner, this roll gradually increases in diameter as it the same to be fed past the tracker board with increasing speed and correspondingly accelerating the tempo of the music, particularly .toward the end of the sheet. This is especially objectionable when such instruments are used in dancing schools and skating rinks where a steady and invariable tempo must be maintained.

The object of my invention is to provide such perforating machines with simple means for feeding the blank music sheets past lthe punches or perforating devices at a variable or gradually increasing speed corresponding to the accelerated speedwithwhich the sheet is caused to travel when applied to amusical instrument. The perforatios of the sheet are by this means, punched farther and farther apart from the front to 'ard the rear end of the sheet and the accelerated travel of the sheet when in the instrument is compensated for by the correspondingly increased spacing of the single perforations and the increased spacing and length of the slots or elongated perforations, thus playing the music at a steady and uniform tempo from beginning to end.

In the accompanying drawings consisting of 3 sheets; ,Figure l is a fragmentary verti'- cal longitudinal section of a perforating machine embodying the invention. Fig. Q is a transverse section in line 2---2, Fig. 1,. Fig.

3 is a fragmentary top plan view of the machine. lfigs. 4 and 5 are elevations of opposite sides of the sheet-feeding mechanism. Fig. 6 is a rear` view of said mechanism. Fig. 7 is a cross section and Fig.'8 a longitudinal section of one of the feed or take-up rollers of the machine. Fig. 9 is a fragmentary. plan view of the front and rear portionsl of a music sheet perforated by the improved machine, showingin an' exaggerated manner, the increased spacing of the perforations and the lengthening of the slots toward the rear' end of the sheet.

Similar letters of reference indicate corresponding parts throughout the several -v1ews.

A indicates the bed of the machine supported by legs A1, and 'A2 the side frames I 'rising from the bed.

B indicates thc usual perforated mastersheet which controls theperforating or punch mechanism hereinafter described.

This sheet is wound upon the customary sup ply rolleil B which is carried by brackets b securedA to the side frames A2. From this roller the master-sheet passes through a.

guide and tension device l carried by the bracket and under a guide rod 0,1 `thence through thecustomary transverse vertically-movable bar D and over and iinder guides c, c1 thence over a feed roller F having pins which engage holes in the margins of the master sheet; and thence around a guide roller y to the take-up roller Gr to which latter it is suitably fastened. The feed roller F is intermittently rotated from the main driving shaft H by any suitable means, the mechanism shown in the draw ings consisting of a. ratchet wheel h secured to the shaft ofsaid roller and a vibrating arm 11.1 carrying a pawl h2 which engages said wheel. -This arm is actuated by a., cam lz. secured to a counter shaft hf* driven from the main shaft by a sp/rocket chain h5 and sprocket wheels 71., if.' d

The take-up roller G of the master-sheet isdriven from the counter shaft h4 by a belt I running around pulleys 2, l on said sh`aftand the roller shaft. The pulley z" is loose on the shaftr of the take-up roller. and a sping 2 holdsx it in frictional engagement with a disk 3' fixed to said shaft, by which construction thespulley 1" slips on its shaft -whenever-the slack in the master 'sheet is fully taken up.

'carrying the perforated die plate f I n u l i The punch or perforatmg mechanism l punch and rendering the latter inoperative.

may be ot" any suitable or well known coni struction. lts particular construction forms no part of my present'invcntion and a brict description ot' the same will therefore suitice.

J is the vertically reciprocating cross head with cross shatt The which the punches /tf1 coopera-tc, the head receiving motion from the main H by an eccentric and strap fly. punches are guided in plate, a cross bar Zit carried by the cross head J and a fixed stripper bar l cmmectied by bolts ll with a'cross piece. L secured to the side trames A?, as best shown in Figs. l and 2.

M indicates the gang ot longitudinallymovable stop bars arrangetil above the punches respectively and controlling their action, These bars, which are arranged between horizontal guides m, are urged forward by individual spril js m and returned by a universal bar 'mi carried by rock arms mi' acted on in one direction by camsl mi* on the shaft' /Ll and in the opposite direction by lsprings m0. Each ot-tlicse stop oars is provided in its umlerside with a notch nf which in the normal retracted position ot the bar, shown in lll-ig. l, registers with the upper end of the correspoiuling punch, allowing the latter to recede into the notch when the die plate rises and preventing they punch from pertorating'the music sheet or sheets N whielrpass through the horizontal slot ot' the die. plate. lVhen, however. one ot said hars is allowed to move to its forward-position under the action ot` its spring m, its notch'm breaks register with the' punch, thus resist-ing or stopping the upward movement ol the punch and pertorating the music sheet or sheets by the next upward stroke or" .the die-plate. y,

The stop bars )l are normally locked in their retracted position by individual vert i cally-swinging catches o which are adapted to interlock with notches ol in the upper edges of the bars and which are urged upward out otl engagement with the same by springs 02. 'the downward or locking movement of these catches is controlled by pins 71 extending upwardly therefrom through openings in the cross bar D and cooperating with the master-sheet., The bar D is carried by a vertically swinging frame g pivoted at g1 to 'the side' frames A2 and vibrated in one direction by a spring g2 and in the opposite direction by a cam g3 on the shaft 71.4. Then an in'iperlorate portion ot' the master-'sheet is Opposite a given pin p and the bar D descends, theI corresponding eat-ch o is depressed into engagement with the notch 0l of the companion stop bar M, locking the latter against forward movement, keeping its notch mi in register with the corresponding openings in the die- 1 mains in its elevated lVhcu, however, a perforation in the master'- sheet registers with said pin 7), the latter reposition andthe descending har D and master sheet slide idly over the pin, leaving the corresponding stop bar M unlocked and permitting it to advance under the action of its spring m1, thus moving the lower notch m5 of the bar out of register with the corresponding punch, blocking the upward movement of the latter and compelling it to perforate the music sheets when the die plate ascends, as before de scribed.

The webs or blank sheets N to be perforated are wound upon the usual supply rollers R journaled in standards R1 and ass the-nce over and under guides 7', r1 through the dieplate 7a, under guide rollers r2, under or over a vertical series of similar rollers fr" and thence to individual take-up rollers S to which the front ends ot the sheets are fas tened so thatthey are wound upon them in the same ina-nner as when attached to the take-up roll of an automatic musical instrument. Any suitable fastening means may be employed tor this purpose, but cach roller is preferably provided in its face with a longitudinal groove .5 in which the. end of the sheet is clamped by a key or feather si, as shown in Figs. 'l' 'and S. rlhe several takeup rollers S are jeurnaled in standards T mounted on the bed of the machine on the rear side of the puitching-mechanism, and al1 intermittent* rotary n'iovement is imparted to these rollers by anysuitahle driving mechanisn'i. ln the construction shown in the drawings. each roller is provided at one end with a gear wheel and the wheels of adjacent rollers are connected by idler gears .fl Iiournaled on an upright supporting' bar or frame t2 movable toward and from theI gear wheels t, so that'the idler gears may he collectively moved out of gear with said wheels to permit the several rollers to be turned by hand individually in attaching the sheets of paper thereto. The supportingbar t2 is pivoted to the.adjacentstandard at one end, preferably its lower end, as shown at t while its upper end has a notch which 'receives a clamping bolt tf carried hy the adjacent standard, as shown in Fig.

One of the take-np rollers is provided at the end opposite that to which the gear z is fastened, with a driven gear u which is connected through an idler gear ul with a gear wheel'iz.2 secured to a short transverse shatt 1.1.3 to which is also fixed a ratchet wheel 1,14. The latter is intermittently turned by a feed pawl ui carried by an oscillating arm u. pivoted on the shat't un and connected by a rod `ul with a Wrist 'a5 on the pulley a'. .As shownin Fig. 4, the arbor o'l the idler gear al is carried by an adjustable arm e pivotcd upon the shaft u and having a slotted seg to the length of the bars in the piece of music' which is being cut; or in other words in accordance with thc tempo of the composition.

The take-up rollers S are of the same diameter the take-up rollsof the autoi'natic` musical instruments withwhieh'the music sheets or rolls are to be used and said rollers are driven at a uniform speed. It follows Jthat the blank music sheets in. the perforating' machine are moved past the punches at a gradually increasing speed owing to the growing diameter of the take-up rollers S in the same manner and with the correspondingly accelerated speed at which the music sheet is moved past the tracker-board of an automatic musical instrument'.v The result is that the single perforations representing notes of the shortest duration are spaced farther andfarther apart from the front toward the .rear end of the sheets in a corresponding measure and the length as well as the spacing of the elongated openings or slots produced by a succession of two or more connected or overlapping punch holes likewise gradually increased, .so that notwithstanding the accelerated travel of the music sheet in the instrument, the music. is rendered at. a steady and uniform tempo throughout the length of the composition or compositions on the sheet.

I? rom an inspection of Fig; 9, the relative spacings of the single perforations and the lengths of the slots in opposite end-portions of a music sheet will` be observed, the spacing and length being greater in the right hand portion of t-he figure which represents the rear portion of the sheet.

In the drawings, eight take-up rollers S are shown, but. a greater or less number may be employed.

T he means master sheet and for music sheets past the punching mechanism may be of any ordinary construction, the essential feature of they invention being the provision of a take-up roller for the music sheet which is the counterpart of the takeup roll of the instrument in which the sheet is afterward used and upon which the blank sheet is wound, sothat by theincreaslng d'iametcr-of'said vroller the sheet is fed with an accelerated speed corresponding to that for guiding and feeding the of the music sheet when in use.

Musical compositions ent speeds, and to permit of this changeable drive, different sized gears u are employed, as hereinbefore described.

I claim as my invention:
