To all whom it may concern:

Be it known that I, HARRY PALEY, a citizen of the United States, and resident of Millie, county ofNorfolk, State of Massachusetts, have invented an Improvement in Apparatus for Feeding Roll-Mnsic, of which the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawings repre senting like parts in each of the several views. i 4

This invention relates to mechanism for feeding music, which is printed on asingle strip or ribbon of paper, in contradistinction to m-usic as most commonly printed on separate sheets which are arranged inbook form, my present improvement being specially valuable and convenient for use with pianos, organs and the like instruments, which are played with both hands. In carrying my inventlon into practical effect I print themusic in blocks which are substan tially the same as the pages ofgsheet music as commonly published but, instead-ofprinting each page or block on a separate sheet of paper, Iuse a continuous strip or ribbon of paper, and I place the pages or blocks in proper sequence so that the ribbon may be mounted upon Irollersand then manipulated, after the manner of a panorama, by means of automatically actuated mechanismwhich may be controlled, by a single movementof one hand or a foot of the musician, thus feedingthe sheet along laterally with an ins termittent movement which brings each successive page or block of the music into view as needed. y i j The foregoing and other objects and ad vantages of the invention will more fully appear from the, following detailed description, and the distinctive features of novelty will be pointed out in the appended claims.

Referring to the drawings:

Fig. 8 is a relatively enlarged view of one of the rolls upon which the music is wound, intermediate portions thereof being broken away;

In these drawings th'e numeral indihousing in the side portions of which are located vertical rolls 11 .and. 12,the upper end of each of said rolls being :journaled in a suitable bearing in the housing, as seen in Fig. 1. The lower end of roll 11 is secured to or stepped in a sprocket roll 13 and the lower end of the roll 12 is likewise stepped in a sprocket roll 14, andthe said rolls 13, 1 1 are engaged, and driven (as I will explain hereinafter), by means of a sprocket upon the roll 11, which may be termed the delivery roll, andthe free end of said paper is attached to the roll, 12,

which is to serve as the take-up roll, the arrangement of the described parts being such that when the rolls 11, 12 are rotated intermittently, the pages of the music printed upon the strip of paper are successively exposed to View in the front opening of housing 10. By having the ends of the rolls 11, I12 stepped or socket-ed in the respective sprocket rolls 13, 1 k as described, it is possible to remove the rolls 11, 12 and to interchange them with respect to the

sprocket rolls

13, 14 sothat the music sheet thereon may be run back without re-winding thereof and thus it is possible to have the music printed on both sides of thepaperstrip or web. The rolls 11, 12 hearing thepaper strip being removable it is possible to sub,- stitute different pairs of rolls bearing different series of songs or other musical notations at will. In order to thusfeed the paper along I have provided simple and reasonably cheap. mechanism which I will Mounted between the opposite sides of the sprocket belt 15 is a barrel 16 in which is a coiled spring 17 one of whose ends is secured to the said barrel, its other end being secured to a fixed arbor 18. The outer, circumferential, face of barrel 16 is provided with radial pins 19 which are adapted to engage the openings in the belt 15 in such manner that, when the barrel is rotated, the belt will be started into action and will rotate the sprocket rolls 1.3, 1.4; and the connected rolls 11., 12.

Mounted fixedly on the arbor 18, at the under side or base of barrel 16, is a ratchet disk 20 which is engaged by a pawl 21 that is mounted upon the barrel and serves to prevent the accidental unwinding of the coiled spring 17. The barrel 16 is loosely mounted upon a fixed base 16 which is formed with a lateral extension 16 which serves as a bracket by means of which the base may be secured to the back side of the housing 10. The sprocket belt 15 is provided with one or more openings 22 which are engaged normally to the free end portion of a stop lever 23 which is pivotedin bearings 24 formed on the lower face of the base 16*; the other end portion of said stop lever being formed as a push button 25 by means of which the lever 23 may be rocked in order to withdraw the upper end of said lever from the opening 22 and so that the barrel may be rotated 011 the arbor. Lever 23 is held normally in its operative position by means of a spring 26, as will be understood by reference to Fig. 7 of the drawings. Screwed fixedly into the lowerend of the arbor 18 is a milled thumb piece 27 by means of which the arbor may be conveniently rotated whenever it is desired to wind up the spring 17.

Assuming that the strip of music paper has been coiled upon the roll 11, with its free end attached to the roll 12, and it is desired to feed the paper along so as to expose to view the next block of music, it is only necessary to push the button 25 with a quick movement and then release it. The upper end of the stop lever is thereby withdrawn from the opening 22, thus permitting the spring 17 to start the barrel in revolution and thereby'moving the belt 15 and rotating the rolls 11 and 12 sufficiently to feed the music paper forward. Meanwhile the end of the stop lever rests upon the rotating barrel 16 until the opening 22 comes into register again with the end of said lever which then enters the opening 22 and thus stops the barrel and its connected movable parts. It will be understood that, by simply pushing the thumb-piece 25, the several pages or blocks of music may be successively brought into view. Though I have herein shown the stop device as controlled by a thumb piece 25 it is to be understood that in a broader aspect this is merely illustrative and intended to typify any suitable manually controlled device which may be either hand operated or foot operated.

Having described my invention, what I claim as new, and desire to secure by Letters Patent is:

1. Apparatus for exhibiting and feeding intermittently a music paper or like web, comprising a pair of rolls, one constituting a delivery roll and the other a take-up roll, a sprocket belt engaged with said rolls, a motor unit consisting in a barrel equipped with sprocket teeth engaging said belt with a spring housed therein, and a manually controlled device engaging said belt to control the movement of the paper sheet by said motor unit for presenting a series of songs or like subjects successively.

2. Apparatus for exhibiting and feeding intermittently a music paper or like strip consisting in a pair of rolls constituting a delivery roll and a take-up roll respectively, driving means to which said rolls are detachably fitted whereby they may be interchanged for the purpose stated, said driving means consisting in a sprocket belt en- .gaged with sprocket rolls, and a motor unit consisting in a barrel having sprocket pins projecting therefrom to engage said belt, a spring housed in said barrel, and a manually controlled stop device arranged to engage said sprocket belt to limit the movement thereof for presenting a series of songs or like subjects successively to view.

3. Apparatus for exhibiting and feeding intermittently a music paper or like strip consistingin a pair of rolls holding the strip between them for horizontal movement, operating means for said rolls detachably engaged therewith comprising a sprocket belt, a motor drum engaged directly with said belt, and means engaging said belt for permitting predetermined manually controlled movements of said rolls for successive exhibition of subjects on said paper strip.

In testimony whereof, I have signed my name to this specification.

HARRY PALEY.
