T0 all whom t may concern.'

Be it known that I, ALFRED J. SWING, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Cutting Perforated Music-Sheets, of which the following is a specication.

My invention relates to means for controlling selectively a series of, punch members operated through an intermittent feed of a master sheet, relatively, with the reciprocation of the punch members in the manufacture of music records. v

The object of my invention is to provide ing a music record for a musical instrument,

having a series of punches, withreciprocating means for operating said punches, and means for selectively controlling the operation of said punches coacting with the master sheet, intermittently fed relative to the reciprocating means. H

Another object of my invention is to provide a machine for perforating sheets, having a series of punches, with reciprocating means for operating said punches, and selector means interposed between said reciprocating means, and a master sheet intermittently fed, relative to said reciprocating means for ycontrolling the actuation of said punches, said selector means being guided in a direct path between said reciprocating means and master sheet, with one end thereof adapted to reciprocate with said reciprocating` means.

Another object of my invention is to provide a machinefor perforating sheets having a series of punches, with reciprocating means for operating lsaid punches and selector means cordinate with leach `of the punches of the series and interposed bea machine for perforating sheetsin prepar-` machine, embodying the principles of my invention. Fig. 2 is a section on line 2, 2, Fig. l. Fig. 3 is a perspective view of one end of the roll for feeding the paper to be perforated. Fig. 4 is a partial top plan view of the :machine` with` certain parts removed, and in which the latter dimensions have been exaggerated for the sake of clearness.

A represents the sheets to be perforated, passinoV over a roller B, and above the punchblock ,and fed by means of the feed roll D. The roll D, upon one end thereof is provided with a ratchet wheel E.

eV represents a pivoted` arm, carrying a pawl e', pivotally connected thereto and engaging with the ratchet wheel E. rlhe arm e is connected to an eccentric link F, said eccentric link being connected to the main driving shaft G. Said shaft is driven from any suitable source. Thus, by each rotation of the shaft G, the arm e and pawl c will be actuated and cause an intermittent partial rotation of the roll D.

62 represents a check pawl, adapted to engage with the ratchet wheel E, to prevent reverse movement vof the roll D. The roll D, at each end thereof, is provided with a series of arms H, each pivotally connected and having a roller 71. engaging with a stationary cam J. The arms H are normally held or maintained in contact with the cam surfaces by means of the springs 71.. The cam J is provided with a radial surface j and a cylindrical surface j', connected by the curved surfaces jg, to operate or swing said arms H, as the roll D revolves, moving the arm to and from the periphery of the roll to grip the paper or sheets and feed the same therewith. Thus, when the rollers 7L pass over the cylindrical surface j the arms will be swung to engage and grip the sheets between the arms and periphery of the roll D, and when the rollers pass over the surface j, they will be swung to a released position, as shown in Fig. 2. This construction of gripping means maintains the sheets smoothly over the periphery of the roll with accuracy of feed, eliminating any creasing of the paper or looseness between the several sheets and prevents any buckling or distortion. Such feed is very essential in the operation of perforating machines, simultaneously perforating a number of sheets, as all sheets should be the eXact duplicate and to correspond relatively to the master sheet for producing a record for musical instruments.

The shaft G is provided with the eccentrics K, connectedby links 7s, to a crossplate L, said plate is mounted in suitable guides and reciprocated vertically.

nfl represents a series of punches slidably mounted in the guides N, coperating with the punch block to perforate the sheets A, one punch member being provided for each line of perforations desired in the sheets, and in number representing the various keys of the musical instrument. Each punch member M is provided with a stop lug m, adapted to engage upon a reciprocating bar O, the said bar being normally held in an elevated position by means of a series of springs 0. By this arrangement, it will be seen, that after each operation of the punches, the bar O will serve to automatically raise the same, until the stop lugs m engage the under side of the upper guide N. The cross-plate L is provided with a bar l), provided with slots, into and through which the selector bars Q, respectively project and form a sliding bearing therewith. Each selector bar Q is provided with a block Q, having a notch Q', adapted to engage with the upper end of a relatively alined punch-member M, when the selector bar is in operative position. This end of the selector bar is adapted to reciprocate with the cross plate L, but in normal position the block Q is out of alinement with its respective punch member, and therefore will not actuate the same on the downward travel of the cross plate L.

Q2 represents a lug projected from each selector bar, adapted to engage against the cross-bar R, fixed to the oscillating levers r, said oscillating levers being suitably pivoted to the frame of the machine and preferably one lever is employed upon each end of the series of punch members.

r represents a link pivotally connected with the oscillating lever 11 at one end, its opposite end being connected with an eccen tric r2, fixed upon the shaft Gr, to relatively actuate the lever 7", with the reciprocating movement of the cross-plate L, to return the sector bars to their normal position.

Q3 represents a spring, one end of which is fixed to a respective selector bar, its opposite end to the guide plate Q4, said guide-plate being provided with a series of slots coincident with the selector bars and through which said selector bars respectively project.

-This guide plate Qt also serves to maintain the alinement of the selector bars, relative to their punch members and also relatively to each other. Y

U represents a perforated master sheet adapted to be fed over the guide bar T, and over the feed roll V, and between said roll and the roller V, into the receiving tray V2.

The roller V is fed substantially the same as the papel' feed roll D, and likewise provided with a ratchet wheel.

o2 represents an arm pivotally connected upon the shaft of the feed roll V, and to the shaft G, through the linlr 'U' and eccentric o. y y

'v3 represents a pawl pivotally mounted upon the arm o2, adapted to engage with the ratchet wheel, whereby an intermittent feed is imparted to the master feed roll V, relatively with the reciprocation of the/cross plate L.

The arrangement of feed and cross plate reciprocation is such as to feed the record sheet A, and master sheet U simultaneously upon each upward movement of the cross plate, and after the selector bars and punch have returned to normal.y position.

The opposite ends of the selector bars Qy are provided with the plungers s slidably mounted within the guide plate s, and relatively alined with a series of orifices t, formed in the guide plate T.

S .represents a flexible strap interposed between the forward and rearward ends of the selector bars Q, adapting the forward end to yield or swing vertically with the reciprocation of the cross-plate L.

The master sheet U is fed so that each horizontal line of perforations alines with the orices t, to enable the selector bars when released from their' forward position by the oscillating lever r, to move rearwardly and permit the plunger ends s, to pass through such alined perforations of the master sheet open to the orifices t. This action will cause the blocks Q of the selector bars to aline with the punch members of all such selector bars as have been permitted by a given line of perforations iny the master sheet, to project into the orifices t. The remainder of selector'V bars engage an unperforated portion of the master sheet, and are maintained in their normal position with the punch blocks Q, out of alinement with the punclrmembers M. A downward movement of the cross plate L will actuate the punch members whose respective selector bar has engaged through the relative perforation in the mastersheet'permitting the punch blocks of such selector bars to be brought between the cross head and punch member.- Upon an upward movementV of the cross plate L the selector bars are simultaneously withdrawn from the perforations of the master sheet and moved to normal position by the cross bar R and its lever and pitman mecha# nism and with an intermittent feed of both master and record sheets operating` during the upward movement of the cross plate L, for a second operation.

As illustrated, the springs Q3 are employed to impart rearward movement to the selector bars when released by the cross-bar R.V

By this construction of selector bars interposed in a substantially horizontal plane and in iiXed guides between the master sheet and punch cross-plate and of substantially integral construction, no lost motion 0r play is had, and the plunger ends Apass freely through the perforations of the master sheet, and Without injury thereto, Which is of material advantage in accuracy of reproduction and in lengthening the life of the master sheet.

It is obvious that various means or forms may be employed for intermittently feeding the master and records sheets relative With the reciprocation of the punches and actuating mechanism, but the construction herein shown is merely illustrated as a means for producing intermittent feed, it being obvious that various Ways may be employed for accomplishing the same result. The same can also be said as to other details of construction, illustrated and described herein, Which may be variously modified, Without departing from the features of this invention, and I do not Wish to be limited to such construction, except as specifically set forth in the claims.

Having described my claimz l. In a machine of the class described, a series of perforator members, operating means for said perforator members, a perforator functioning member interposed between said operating means, land each perforator member, a master sheet, a reciproinvention, I-

cating'inger for each perforator member cooperating vvith the master sheet to selectively control its respective perforator member, and iieXibly connected to its perforator functioning member, and means for returning the parts to their normal position.

2. In a machine of the class described, a plurality of perforator members, operating means for said perforator members, a functioning member for each perforator member, a master sheet, means for feeding said master sheet at timed intervals relative to the movement of said operating means, reciprocating fingers coperating with the master sheet and movable in a plane at right angles thereto, each flexibly connected to a respective perforator functioning member.

3. In a machine of the class described, a perforator member, reciprocating means for said member normally disengaged therefrom, a connector element confined againstl lateral movement capable of being moved to connect said perforator member and recipcating means, a master sheet fed at timed intervals relative to the movement of said reciprocating means, and an element flexibly connected With said connector element slidably movable toward and from said master sheet, and confined against transverse movements.
