Fo @ZZ whom, it may con-cern.:

Bc it known that I, HENRY IIORTON, a citizen ofthe United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Machines forFunching Feri'orated Sheetullnsic, and I do hereby declare the following to be a fullLclear, and exact description ol" the invention, such as will enable others skilled in the art to which it appcrtains to make-and use the same.

This invention relates to machines for perforatin paper by punching holes in obedience to a pattern 'which is arranged on the inachine to mov c', together with the paper, step by step, and govern the action ofthe punches.

Hy ncwlpinvented machine was specially designed for the purpose of pcrforating the sheet-music used in connection with the anto-` matie musical wind-instruments described in United States Patents No. 196,529 and No. 210,24, granted to me October 30, 1877, and December 1878, respectively. The notes ot this sheet-music are represented by rectangular perlorations, short and long, according to the respective values of the notes, the long perforations or note-holes being multiples of the short note-holes. In order to produce such perforated sheet-music, I constructed the peri'orating machine with rectangular notepunches ol' exactly the size of the shortest required note-hole, and made the length of each step of the intermittent feed oi the music pattern and paper also exactly equal to the length ol' the shortest notc-hole, so that if the same punch is caused to punch successivelyit will punch a note-hole of a length equal to the length of the shortest note-hole multiplied by the number oi successive punchings. As regards this capacity of the machine of punching rectangular note-holes varying in length er value, it does not diiler from perforatingmachines previously known.

)Iy invention is designed as an improvement on suehmaehines; and it consists of certain novel mechanical combinations which will be duly described, and specifically pointed out in the claims at the close of this speciile-ation.

In order that my invention may bc clearly understood, I have illustrated in the annexed drawings, and will proceed to describe the iirst practical machine built by me embodying all the principal features of said invention.

Figure 1 is a perspective view of the ma- 55 chine. Fig. 2 is an end elevation thereof. Fig. 3 is a plan view. Fig. 4C is a vertical longitudinal section on line x Fig. 2. Fig. 5 is a vertical transverse section on line y y, Figs. c, i', s, 9, i0, ii, i2, is, it, i7, and 19 so are illustrations of various details ofthe inachine. Fig. 1S illustrates a music-sheet perforated by my machine. Fig. 15 is an enlarged view similar to Fig. et, without the ilywheel. Fig. 16 is a horizontal section on line 65 z c, Fig. 2. Fig. 19L is a vertical section through the feeler-stock, taken on line a' fw, Fig. 2.

The bed A of the machine is supported on legs to raise it to a convenient height. The front side of the bed is constructed with two 7o parallel longitudinal rails, c and a', forming the shears -for the support of the pattern slide or carriage C. it the rear side of the bed a stout standard, B, is mounted, on the upper end of which a long horizontal sleeve-bearing, 75 B', standing at right angles to or across the bed, is formed for the support of the drivingshaft D. Between the rail c and the standard B the top of the bed is provided with three parallel transverse ribs, al as a, the two chan- 8o nels between which form the seats for the dies I and i. Tables F and F are secured upon the bed, extending in opposite longitudinal directions from the ribs ct and alf. respectively, being substantially flush with the top of said 85 ribs and parallel with the shears for the patterucarriage. The central rib, ci, is also flush with the top of the tables. rllhe standard B is constructed with a vertical web or guide, B2, which extends across the bed directly over 9o the central rib, ai, thereof, and rests at its inner end on top of the rail c', to which it may be secured. A space of suitable height is left between the top of rib a? and the bottom edge of the web or guideB2 for the passage of the 9 5 paper to be punched. The vertical inner edge of this web is constructed with latcrally-projecting wings Z) and b. This web of the standard constitutes theguide for the vertically-reciprocating head G, which carries the punches loo and their adjuncts, and will be hereinafter so designated.

By referring to the illustration of a portion of a sheet of music, Fig. 18, it will be observed that the longitudinal rows of note-holes are arranged closely adjoining-that is to say, so that the adjacent edges of two rows are on the same line. This forni of sheet-music is very desirable, since it enables me to reduce both the width of the paper and the width of the instrument for playing any given number of notes. Now, though it may not be impossible, it is impracticable to perforate these musicsheets with a single row of punches, because the punches would have to be placed closetogether, so that the dies would form a continuous slot and afford no side support to the paper under the action of any one intermediate punch. To obviate this difficuity I use two rows of punches, the note-punches II of the forward row being arranged opposite to the spaces'between the note-punches lt of the rear row. In other words, the note-punches of the forward row are arranged alternatingly to the note-punches of the rea-r row. The head G embraces the guide B'f, and the rows of note-punches are applied to the head on opposite sides of the said guide, the distance between the adjacent sides of the rows being a multiple of the thickness of the note-punches measured in the longitudinal direction of the machine.

The note-punches. of one row and their adjuncts are constructed and combined like the note-punches of the other row. Hence, to an understanding of the whole note-punching mechanism, it will be sufficient to i'ully dei scribe, by the aid of capital letters of reference, one row of note-punches and their adjuncts, and to mark the corresponding parts of the other row with the same, but small, letters, said description applying equally well to either row. The note-punches II are rectangular in. cross-section, of exactly the size of the smallest or shortest note-holes to be punched. They are tted in vertical channels formed in head G, and the shank of each one is provided with a notch, H, into which the point' of a screw, H2, screwed through the side of the head, extends, so as to hold the punch in its channel, but allow it to have a limited endwise motion therein. The punches protrude from the bottom of the head, and directly in line with them a stout slotted bar or guide, I, is arranged above the dies, through the slots of which the punches descend to the dies, and by which the punches are supported, so as to prevent them from springing in the longitudinal direction of the machine, as they would be apt to do were it not for this guide, in punching elongated note-holes, because then there is an uneven strain on the punches in said direction. The shanks of the punches decrease in length toward the standard B for no' particular reason except to favor the construction of other parts. Directly above the upper end of the shank of each punch a lock-bolt, H3, is arranged to s li'de transversely in the head. The outer end of each lock-bolt is pivoted to a separate lock-lever, Hby which the lock-bolt A can be shot across the top of the punch and prevent it from rising in its channel. In the normal position of the parts the lock-bolts are all held retracted by their respective levers. The inner ends of the lock-bolts are made oblique, so that they may readily ride over the top of the punches and force them down in the act of locking-them if they should have failed to descend to their lowest position by their own gravity on the ascent of the head. The lock-levers are separately operated to shoot the lock-bolts over the punches by a corresponding number of sliders or feelers,7 K, as I term them. These feelers are fitted in a row of vertical channels in the stock G, which projects from the head G transversely across the pattern-slide or carriage C. The lower protruding ends of the feeler are of considerably less thickness in the longitudinal direction of the machine than the note-punches, the reason for which will appear presently. Their shanks are thicker than their protruding ends, so that each has ashoulder to abut against a retaining-strip Xed part way across their channels on the bottom edge of the stock to hold Athem therein. Each feeler is adapted to operate on the particular lock-lever assigned to it.

. To this end each lock-lever is provided with a pivoted cross-bar, H5, one end. of which passes through a corresponding horizontal hole in the stock Gl to the corresponding feeler. The inner end of. the cross-bar is beveled to the slant of the Cain-grade K', forming the lower edge of a notch, K2, in the feclcr. Vhen the head with IOO its stocks is at its highest elevation, t-he feel- A ers should rest with their shoulders on the retainingstrip, and the cross-bars H5 ofthe locklevers should reach into the notches K2 of the feelers to about the bottom of the notch, so that if any one of the feelers be arrested in its downward movement with the head the cam-grade K of such feeler may act on the cross-bar H5 of' its corresponding lock-lever and cause the latter to shoot its bolt. After a feeler has thus acted, both itA and its corresponding lock-lever require to be restored to the normal positions before the next descent of the head. This I prefer to accomplish by positive means, as follows: A' bracket, L, is Xed to the wing b of the guide B2, and overhangs the feeler=stock, being so arranged that its bottom side shall nearly touch the top of the feeler-stock when raised to its highest on the plate in the required order.

push such cross-hars into the notches o'f the i'eelers. The lower ends ofthe restoring-rods and the outer ends of the cross-bars of the lock-lever are reversely beveled, so that the former may be enabled to properly push the latter inward at right angles. Aiixed bar, L2, is arranged to support the outer ends oi' the cross-bars H5 under the action of the restoring-rods. The head G is reciprocated vertically by the eccentric D on the front end of the driving-shaft through the means of the pitman D embracing the eccentric at one end, and taking hold with its other end of a stout pin, D, journaled in a box, D", which is secured between the two sides of the head G, and fits snugly1 in an opening formed in the web or guide B2. The dies are separate blocks, each one of which is secured by a separate screw, l?, so that it may be readily adjusted accurately to its corresponding punch. Below the rectangular hole through its top the die is counterbored, as shown iu Fig. 15, to form proper clearance for the discharge of the punched paper clippings, which pass from the dies through suitable holes in the bed A, and may be caught by a suitable receptacle placed under the bed.

The music-pattern hl, for governing the operation of the punches, is ixed upon the pattern slide or carriage G,and consists of changeable pins c and blocks ci, erected upon a metallic plate, m, in which numerous pin-holes, c, are bored in parallel longitudinal and transverse rows for the reception of said pins. There must be Aat least as many longitudinal rows of pin-holes in the plate as there are punches and i'eelers, and each t'eeler is directly over a longitudinal row of such pin-holes. Any desired music-pattern is produced by erecting the pattern-pins and pattern-blocks Vhen erected the pins and blocks are high enough above the plate to strike the ends of the feelers and arrest their downward movement with their stocks for a space sufiicie-nt to cause such arrested l'eelers to operate their corresponding lock-levers. Blocks cL are used in conjunction with the pins c to obviate the necessity of boring twice the number of pin-holes in the plate m. The edges of the blocks are concaved to iit the pins and be held in position thereby. The music-pattern and its carriage are moved intermittently, or step by step, the length of each step being exactly equal to the thickness of one of the notepunches measured in the longitudinal direction of the machine. The distance from center to center between two adjacent pin-holes, c, of any one longitudinal row is exactly equal to two feed-steps. The pattern-carriage is provided with a longitudinally-arranged screw, M', journaled in sleeve-bearings on the ends of the carriage, so that it may be turned by the handle m', but cannot move endwise independently of the carriage. A cross-pin, me, of the screw is adapted to be engaged by the fork of a sliding latch, mi, on the carriage, in order to lock the screw thereon and prevent it from turning. A nut, N, is applied to the screw M' between the cross-bar a5 and a lug, c, of the bed-plate A, so that it can only turn but not travel on the screw. rlhe central peripheral surface of this nut is provided with ratchet-teeth, upon which a pawl, N, is to operate to turn the nut intermittently and properly feed the carriage with its music-pattern. I so construct my automatic musical instruments as to require the shortest noteholes of the music-sheets to measure onetenth of one inch each in the direction of the length of the sheet` -The screw M has a pitch of two threads to the inch, so that the nut has to make twov whole revolutions in order to move the carriage and music-pattern the distance of one inch. Now, as each feed-step of the music-pattern must be equal in length to that of the shortest note-hole, or (which isthe same) the longitudinal thickness ofthe note-punchesnamely, one-tenth'of one inch-it follows that i the nut must be turned one-fifth of a revolution to move the music-pattern the proper distance at each impulse. Hence the circumference of the nut is divided int-o live equal ratchet-teeth, and the motions of the pawl are duly proportionedv to turn the nut one-iifth of a revolution at each feed. The pawl is arranged under the nut, being pivoted on a pin, a, journaled with its ends in a pair of short lever-arms, n a', mounted on the circular ends of Athe nut, so as to turn freely thereon. The pin nis connected by a pair of connecting-rods, n2 u2, to the downwardly-projecting arm of an elbow-lever, N2, fulcrunied at nl on the standard B. The horizontally-projecting arm of this elbow-lever is connected bya proper joint to the lower end ot' the pitman O', whose upper end eneircles the eccentric O on the driv` ing-shaft. rlhe th row of this eccentric and the leverage of the levers intervening between it and the pawl must be accurately proportioned t0 provide for the required throw of the pawl. The eccentric 0 is so timed with respect to the eccentric D that the carriage and music-pattern thereon will in the operation of the machine be fed while the feelers are above the pattern pins and blocks of the music-pattern; or, in other words, while the punch-head with its feeler-stocks is moving through the upper portion of its ascent and descent The pawl N' has a weighted tail, to hold its bit against the ratchet-teeth of the nut. A spring, n?, xed on the bed, is provided to aid the weighted tail of the pawl in insuring the engagement of the ratchet-teeth. A spring-paul, N3, fixed on the bed, is applied as usual, to prevent backlash oi' the nut. The carriage with its music-pattern may be run back, after punching a sheet, by withdrawing the latch mi; and turning the screw in the reverse direction. The forward end oi' the pattern-carriage is provided with a horizontal bar, C', projecting laterally across the table F', and ,parrying a IOO ` the hub of the .fly-wheel.

thin sheet-metal apron, C2, of about the width of the paper to be perforated, and adapted to pass under the guides B2 and Il c, between them and the dies I z', to reach past the guide I when the music-pattern has been run back to its starting-point. r[he paper to be punched is hooked with its front end to a couple of fixed pins, c3 c, on the front edge of this apron, by which the paper is then drawn along in unison with the movements of the music-pattern. A spring-finger, I), is used to press the paper down on the table F in close proximity to the guide I.

It will be understood that the entire transverse row of notelholes can be punched only by the action of both rows of punches, and it usually happens that some of the note-holes of f the transverse row are punched by the punches of one row and others by the punches of the,`

other row. By passing the apron through be; tween the punches and dies I am enabled to beil gin the punching close to the end of the sheet.,

The driving-shaft carries a loose fly-wheel pulley, B, which can be connected with they shaft by means of a spring-key, Bf, seated in moves through a loose collar, Bt, on the shaft v within the sleeve It is desirable to stop the machine just as the punch-head completes its upstroke. Hence, the key-seat or groove in the driving-shaft is arranged diametrically -opposite to the swell of the eccentric D', since the wedge operates to retract the key when the latter is at the lower side of the shaft. The lower end of the rod B`3 is pivoted to a lever, S, arranged under and across the bed, being pi'voted thereto at s, while its handle reaches to the front side of the patterncarriage for convenience of operation. A springbolt, s, seated in the cross-bar c, is used to partially lock the lever in either of its two positions, the beveled foot of the bolt engaging lightly either one of two countersinks, s2 s, in

the adjacent side'of the lever.

The machine is prepared for operation by first constructing the required pattern for the 'music to be punched. If not already there,

each row of punches.

The

lseries of pins and blocks of themusic-pattern is successively moved under the feelers, said pins and blocks will in their order arrest the corresponding feelers, which will in turn operate their corresponding lock-lever and shoot their lock-bolt across the top of the corresponding punches, causing such locked punches to partake of the whole descent of the punch-head, and punch holes through the pack of sheets of paper. The punches not locked will de scendto the paper only and be arrested thereby, while the head completes its descent with the locked punches. In this manner the required note-holes representing the music are punched in the paper in the pro-l .gress of the operation of the machine.

rEhe machine illustrated punches twentyy,two notes in the transverse direction of the I-sheet, so that there are eleven note-punches in l Besides these notepunches there is a rack-punch, T, in each row to punch the feed-holes on x ofthe music-sheet, iand in one of the rows there is, furthermore, -a time-punch, U, for punching the time-holes ,ly in the music-sheet. The rack-punches and fthe time-punch are controlled by feelers and flock-bolts, precisely" the same as the notegpun ches. n

l As before stated, the machine illustrated `and described was constructed to punch aparticular kind of perforated sheet-music. Its construction would have to be modified in mechanical details for punching a different style of perforated sheet-music.

Having thus described my invention, what I claim is- IOO l. In a machine for perforating sheet-music a reciprocating head, a series of independent.
