To all whom it 'may concern.'

Be it known that I, THEODoRE M. FARLEY, a citizen of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Perforating Devices for Music-Sheets; and I do declare the following to be a full, clean, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aeconjlpanying drawings, and

to the letters and figures of reference marked thereon, which form a part of this specification. I

My invention has reference to machines for producing music sheets of the kind lin use in automatic musical instruments, and is designed to be used in connection with a piano or other instrument provided with a key-board, so that the music w-hich is being played on such instrument'imiy be simultay position for use. f of the perforating devices, illustrating the neously reproduced on one or more of the music sheets.

My device is simple and compact in construction, and can be quickly applied to the instrument without injury thereto. The principal part 'of the machine can also be instantly detached from the piano, at such times as it is not desired to reproduce 'the music.

In the drawings: Figure 1 is a. longitudinal mid-section of my invention, when in Fig. 2 is a detail of one manner of operation thereof. Fig'. 3 is a front view of one of the levers 29. F ig. 4 is a fragmentary view, in plan, of the perforating mechanism, with some-of. the parts broken away.

Similar numbers refer to similar parts throughout the several figures.

The device consists primarily of a series of punches, one for each of the keys of the instrument, and means for imparting movement to the punches, upon the corresponding key being operated. As the several perforat-ing devices and groups of mechanismr which actuate the same are identical throughout the machine, or are common to all of said devices, the description will be limited to one of the units thereof.

1 represents a bed-plate. supported on legs Q, and mounted on the plate 1 is acrossplate 3, having ya' vertical perforation 4. Supported at some distance, above the crossplate 3 is a cross-pirate 5, in which a punch 6 has vertical movement. Immediately shove the cross-plate 3 is a cross-plate (in a perforation in which 'the lower end i the punch 6 -is normally held, such perforation. being in line with the opening It.

Integral with the nnch 6 is an. angular ar'm 8, the end of'which passes downwardly through a perforation in the plate 5, parallel with the punch 6, and in rear thereof. The end of the arm 8 is supported by a lever 9, fulcrumed on a rod 10, supported at each end in a bracket 10, secured to the frame. A contractile coiled spring 11 is secured at one end to the short end of the lever 9, and at the other end to a rod 11a, also supported in the brackets 10u. operates to hold the punch 6 normally in elevatedlposition, as shown in Fig. l.

Pivotally secured to the punch l6, as at a, is a bar 12, having fixed to its upper end an agitator-plate 13, which is provided at its upper end with an upwardly extending key 14. The key lll is held in a slot 15 in a cross-bar 16, supported in the machine above the cross-plate 5. This permits limited movement of the key l-,t and plate 13 longitudinally of the machine.

Mounted on the plate 1, in front ofthe punch mechanism above described, is a pair of supports 1T, (one only being shown) in which is mounted a rotary shaft 18, to'which is fixed a transverse block 19, provided with ay plurality of striker-blades 20, which pass in close proximity to the plate 13 upon the rotation of said block. Fixed to the end of the shaft 1S `is a sheave 21, by means of which rotation may be imparted to said shaft from' the usual motor, or other means.

' upper end contiguous to the lower face of the Ikey 2B, near the forward end thereof. Fixed to the lon er face of the key-bed 22 is a support QT. in which is mounted a rod 12, upon which is fulcrumed a bell-crank lever 29, the upper end of which is connected with the rear end of the lever by means of a short rod or link 30. The lowerend of the lever 29 is provided with a fork 31, which engages the key 14 of the plate 13. Upon the key 23 being depressed by the operator, the forward end of lthe lever 25 is forced The latter meenanism' downwardly by the pin 26, actuatin the lever 29 to throw the key 14 towar s the block 19. The upper end of the agitator 13 is thus brought in line with the outer edges of the striker-blades 20, causing such agitator-plate to be forced downwardly, giving to the punch 6 a corresponding downward movement, until the lower end thereof enters lthe opening in 'the plate 3. That corner of the plate 13 with which the Stricker-blades contact is preferably rounded, to facilitate the movement of the blades thereon. When the pressure upon the key 23 is relieved the plate 13 is returned to its former position by means of a coiled spring 32, attached at one end to the plate 13, and at the other to a vbracket 33, mounted on the frame of the machine. When the plate 13 is returned to its former position the punch 6 is likewise returned to itsnormal position by means of the spring 11, as before mentioned. The vupward movement of the punch is limited by a cross-bar 33a, with which the arm 8 contacts.

One or more paper sheets 34 are passed through the machine, such sheets passing Iirst over a roller 35, mounted in supports 3G, fixed on the plate 1. Above the roller 35 is a similar roller 37, mounted on a shaft 38 which has vertical movement in curved ,slots 39 in the supports 36, such slots being adapted to support said shaft in their upp'er ends when the sheets 34 are being rst 1ntroduced into the machine. The sheets pass from the rollcr'35 over a drum 40, the ends of which serve to keep the ed es of the sheets` even, and from such rum said sheets pass between the plates 3 and 7, andI beneath the perforating devices. -They then passl over a roller 41 mounted in the supports 17, to which roller motion may be imarted to cause the movement of the music sheets through the machine. Above the roller 41 is a roller 42, mounted on a shaft held in curved slots 44 in the supports 17,

similarly to the shaft 38. The rollers 37 i and 42 are of sufficient weight to keep the sheets 34 pressed tightly together in their progress through the machine. From the rollers 41 the sheets 34 pass over a shoulder 45, above which a knife 46 is supported in a frame 47, and adapted to be forced downlwardly past the shoulder 45', severing the sheets 34 at that point, when the piece is complete'. Nothing is broadly claimed herein on the mechanism b means of which the music sheets are cause to pass through the machine, nor on the mechanism by which such sheets may be cut, and further details ofthe operation thereof are not deemed nec'- essary. v 4

48 lre resents a stand, or support, in which are hel,r apluralit of reels 49 from which the sheets 34 are ed into thefmachine.'v A portion of one of the sheets 34 is shown in of this class.

-music sheets are caused to pass through the machine, beneath the .perforating devices. At the same timethe striker-block is continuously rotated, andl as the keys ofthe piano are operated the correspondingkeys 14 are actuated to bring one or more of the plates 13 into the line of movement of the striker-blades, causing a reciprocation of such plates, and a corresponding movement of the punches G, resulting in the perforation of the sheets 34. So long one of the plates 13 is held in a forward position, such plate will be repeatedly actuated by the blades 20, in rapid succession, resulting in a correspondmg rapid movement of the punch which is controlled by such plate. A simple touch of the key of the instrument will result in the contact of the plate 13 by one of the striker-blades, producing a single perforation in the sheets, but if such key is held down for a greater length of time, the punch 6 will continue to operate, and by reason of the movement of the paper sheets ber ath the punch, will produce a perforation of cori responding length in such sheets. The movement of the striker-block is timed with reference to the movement of the music sheets so as to produce perforations therein corresponding to the length of the notes played on the instrument.

It will be seen that in the o eration of my device it will be possible to ieed the sheets 34 through the machine continuously, instead of intermittently, as in some machines When the machine is not in use, it can be readily moved away from the instrument, the device proper being only 'detaehably attached to the instrument through the engagement of the forks 31 with the keys 14.l 1t is obvious that it can be as readily returned to an operative position by rengaging the keys l 14 with the forks. When the sheets have been perforated they can 4be separately rolled on spools at the front ofthe machine, ready for use, or otherwise cared for. v

What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

1. A device of the class named, comprising a plurality of perforating devices, reciprocally mounted in the machine; aplurality of agitator plates, pivotally attached y to said perforating devices; a constantl rotating cylinder; a plurality of radial b des, carrled by said cylinder, the outer edges of said blades being in proximity to said agitator plates; and means for bringing said agitator plates severally into the line of movement of said blades, to be actuated thereby, substantially as described. v
