MACHINE FOR CUTTING MUSIC-SHEETS FOR MECHANICAL MUSICAL INSTRUMENTS.

SPECIFICATION forrningpart of Letters Patent NO. 717,759, dated January 6, 1903. Application filed May 24,1901. Serial No. 61,694. (No model.)

T or whom it may concern:

Be it known that I, WILLARD S. PAIN, of Meriden, in the county of New Haven, State of Connecticut, have invented a new and useful Improvement in Machines for Cutting Music-Sheets for Mechanical Musical Instruments, of which the following is a specification.

A certain class of mechanical musical into struments are provided with what are called music-sheets, consisting of sheets, generally of flexible paper, perforated so as to serve as valves controlling the admission of air to pneumatic apparatus regulating the opera- :5 tion of the sound-producing devices. Usually these sheets are rolled upon rolls termed music-rolls, which are detachably connected with a musical instrument, so that one music-sheet may readily be substituted for another. Such music-sheets are generally cut by machines in which is used a stencil-sheet having the perforations necessary for the music-sheets and serving as a guide for the cutting of the music-sheets themselves.

My present improvement relates to machines using such stencil-sheets and cutting the music-sheets.

A machine embodying this improvement will be described, and then the novel features will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a machine embodying the improvement. Fig. 2 is a plan or top view of the same with certain portions broken 5 away to economize space. Fig. 3 is an enlarged elevation of certain parts on the opposite side of the machine from Fig. 1. Fig. 4 is an inverted plan or bottom view of certain parts upon the same scale as Fig. 3.' Fig. 5 is a rear elevation of certain parts illustrated in Fig. l. Fig. 6 is a vertical longitudinal section of certain parts. Fig. 7 is a side elevation of certain parts shown in Figs. 3, 4, and 5. Fig. 8 is an'end elevation of certain parts illustrated in sectional elevation in Fig.

Similar letters of reference designate corresponding parts in all the figures.

- A designates a roller supported removably in bearings formed in uprights b, comprised in the framework 15 of the machine.

This

, spond with it.

roll may be removed to enable another to be substituted for it, and it is provided with a crank a, shown as secured to one of its journals by means of a set-screw, so that the crank may be readily removed. The purpose of the crank is to rotate the roller in a reverse direction to that in which it turns during the operation of the machine.

- C designates a stencil-sheet which is to be used as a guide in cutting a large number of superimposed sheets of paper or like material in the manufacture of music-sheets for mechanical musical instruments. The stencil-sheet passes around aguide-pulley c, journaled in a portion of the framework B of the machine, and thence it passes around a cylinder D, which has ends 01, fitting loosely upon a shaft D, journaled in the framework B of the machine. The cylinder D is connected by brackets d with the framework 13 of the machine, so that the cylinder will be prevented from rotating.

Upon the shaft D are afiixed toothed feedwheels d C1 The cylinder I) may advantageously be a foot in circumference, and the pitch-line of the sprocket-wheels will corre- VVhen of such proportions, the sprocket-Wheels will have twelve teeth.

Affixed to one-of the journals of the shaft D is a ratchet-wheel D and combined with that ratchet-wheel is a pawl (1 carried by a pawl-lever d oscillated by the rod d of an eccentric d affixed to the main drivingshaftEof the machine, the latter being journaled in the framework B.

One of the journals of the shaft D has combined with it a friction device 61 of suitable construction, for preventing the shaft D from receiving any motion other than that go which may be imparted to it by the pawl d After passing around the cylinder D the. stencil-sheet passes to andaround a take-up roller G, journaled in the framework B of the machine and rotated by a belt g from any 5 suitable source of power. This belt will preferably be loose enough to permit of slippage of the take-up roller G as the winding of the stencil-sheet upon the latter materially increases its effective diameter. Any equivaxoo lent means for preventing slippage may be used.

H designates a horizontally-reciprocating bar working upon pins h, supported by the framework B of the machine. Its reciprocations are produced by eccentrics h, affixed to the main driving-shaft E. With the bar II are combined a number of feelers I, which pass through holes in the bar H and also through holesin a bar J,fastened to the framework B of the machine. Rearward of the bar H they are provided with collars 2'. ends which project beyond the bars J these feelers I are connected with the upper arms of levers K, which are fulcrumed upon a bar 7c, supported by the framework B of the machine, and have their lower arms pivotally connected to rods L. The rods L are connected to rods L. The connection may be made by a hook on the rod L engaging with pins on the rods L. The rods L pass through a horizontal bar L working vertically in slideways formed in the framework B of the machine. It is reciprocated up and down by eccentrics L mounted upon the main drivingshaft E. The rods of these eccentrics are each divided into two sections and connected by spanners Z these spanners consisting of rods having intermediate of their ends milled flanges and their two end portions reversely screwed thereto. Provision is thus afforded for changing the position of the bar L The rods L are connected to springs L, which are also connected to a stationary bar L secured adjustably by screws Z to the framework B of the machine, so that the tension of the springs may be varied.

The rods L have in their under sides notches Z, and below these bars the bar L is fitted withvertical punches M, having heads of a diameter corresponding to the length of the notches l in the rods L. WVhenever the rods L are in such position that their notches Z are over the heads of the punches M, the descent of the bar L will not cause the descent of the punches; but whenever the notches l of the rods L are out of line with the heads of the punches M, the descent of the bar L will cause the operation of the punches.

It will be readily seen that whenever a perforation of the stencil-sheet 0 comes opposite the feelers I the latter will be free to enter those perforations under force exerted by the springs L The cylinder D is slotted opposite the lines of perforations in the stencilsheet, and it contains behind these perforations a stop, here shown as made in the form of a bar 61 The ends d of the cylinder D are provided with slot (i which are parallel with the feelers. Screws c1 passing through the slots and entering the bar d provide for adjusting the bar toward and from the circumference of the cylinder D. Thus the degree to which the feelers enter the cylinder may be varied to secure the proper positions of the notches Z with reference to the punches M. Then the levers K and rods L L will be shifted, so as to bring the notches Z of the corresponding rods L out of line with the At those punches M. The descent of the bar L will cause the punches corresponding to those bars L whose notches are shifted out of line with the punches to be carried down with it. Those feelers which are opposite imperforate portions of the stencil-sheet will adjust the corresponding rods L into such a position that the notches Z will be in line with the corresponding punches M, and the latter will not be operated by the descent of thebar L The punches M work between guide-bars m. The opposi e sides of these guide-bars are faced with felt m. The bars are adjustable toward each other by means of screws m -pressing against said bars and supported by bars m The punches work through holes formed in a table m. Any number of sheets of paper to be'made into music-sheets may be arranged upon the table and will be cut simultaneously and to correspond with the stencil-sheet.

When the bar H is reciprocated away from the cylinder D, it withdraws all the feelers I from the perforations in the stencil-sheet, so that they will not prevent movement of the latter, and when the barH is moved forwardly it permits of the described coaction of the feelers with the stencil-sheet.

The sheets of paper to be made into musicsheets are fed at the same surface speed as the stencil-sheet. The means for feeding these sheets of paper comprise a ratchet-wheel N, affixed to a shaft N and journaled in the framework B of the machine and having afiixed to it a toothed pinion N The pinion N engages with a toothed gear-wheel N mounted upon a shaft N journaled in the framework B of the machine. With the ratchet-wheel N is combined a pawl N carried by a pawl-lever N loosely mounted upon the shaft N and having pivotally connected to it one end of a rod N which is operated by an eccentric N carried by the main drivingshaft E. A spring holds the pawl in contact with the ratchet-wheel. Upon the shaft N are aflixed a pair of sprocket-wheels N", with which sprocket-chains N engage. These sprocket-chains also engage with a pair of sprocket-wheels N affixed to a shaft N journaled in blocks n, fitted to housings formed in the framework 13 of the machine and made adjustable in said housings by means of screws 12. The sprocket-chains N are provided with a number of bars 71, which may be secured to the chains by screws a passing through links of the chains and entering the ends of the bars. These screws also serve as a means for attaching rollers n, which when the links of the chains are in their uppermost position run along tracks m. Above the tracks n are guides n, which prevent the upper portions of the sprocket-chains from rising out of position. The bars 72. are provided with arms n fitted with rollers 47. As

may be seen by reference to Fig. 5, the arms 12. are made in the form of rods having ends engaged with screw-threads upon their end portions. The rollers n operate in connection with cams n afixed to the framework B of the machine above the sprocketchains and their arms. The arms n pass through slots formed longitudinally in the bars 71. and have attached to them castings 'n ,which are shift- Y arm it travels along this guideway it is maintained in that position upon its bar it", onto which it is adjusted. by the cam it". After the said arm is carried out of the guideway n "by its bar 01. through the agency of the sprocket-chains the said arm n will come in contact with a reverse cam n which will slide the arm outwardly along its bar 71. to the position which it occupied upon said bar before having been shifted by the cam n". The movement of the arm of lengthwise of the bar 12. efiects a similar movement of the castings n In each casting n provided at one end with an antifrictionroller 42, which coacts with the under side of a plate n fastened to the framework B of the machine. The lower end of each rod 01 has a clamping head or disk 92 at the end opposite to that which is provided with the roller n vided with arms at, rollers n castings n rods n antifriction rollers it, and clamping heads or disks n, and both of the sets of these parts for the two ends of the bars 01 are combined with cams nhguideways n cams m and plates n Sheets of paper to be manufactured into music-sheets are guided by suitable guides and pass under the plate a and upon the bars 71 carried by the sprocket-chains. As the edges pass under the plate a the arms n will be shifted away from the ends of the bars a sufficiently to carry the clamping heads or disks @1 over the edges of the paper, and when the rods n pass beneath the plates 11 the clamping heads or disks will be forced down upon the sheets of paper, so as to securely clamp them to the bars 71?. The paper will be released after the passage of the rod 71, beyond the plate a.

The operation of the machine is as follows: A roll A, carrying a stencil-sheet, is mounted in the uprights b, and its end portion, which is not cut with note perforations, passed around the cylinder D and its end fastened to the roll G. The end portionis, however, preferably provided with marginal apertures which fit over the sprockets 61 Thepaper to be cut is first brought under the punches M and its end fastened to a bar or bars N of the traveling chain N by the clamping means thereon. The main shaft E is then started, and through it the sprockets d are intermittently operated to feed the stencil sheet around the cylinder. At the same time-the chain N is intermittently moved, which is a rod n Both ends of the bars 12 are probrings successive bars a? under the paper and their clamps into position to be automatically operated by the stationary cams n and re. As the stencil-sheet is fed over the cylinder the note-perforations are brought into alinement with the feelers, and as each trans verse line of perforations is brought into line with the feelers the feelers are permitted to move forward toward the stencil-sheet. Only those feelers pass through the stencilsheet which are before openings, and this movement of each feeler sets its slide-rod to cause its punch to be forced through the paper sheets which are beingformed into musicsheets. After the operation of the punches all of the feelers are withdrawnand a feeding forward of the stencil-sheets and musicsheet takes place. After the stencil-sheet has unwound from the roll A it is rewound thereon. Another stencil-sheet may then be substituted.
