To (all whmn it may concern:

Belt known that I, HENRY PRIoE BALL, a citizen of the United States, residing at New l York city, county and State of New York, have invented certain new and. useful Im- Musical Instruments, or which the following is a specification.

My invention relates generally to musicrolls for use in mechanical musical instruments, and more particularly to a support or mounting for such rolls.

The present practice of providing wellknown types of mechanical musical instruments with special bearings for the 1nusicrolls of a form and arrangement such that v rolls for one instrumentfor example, the i as the angelus, has resulted in limiting the selection of music of that offered for sale by the maker or some one acting for the maker of the particular instrument used. In order to overcome this difficulty, my invention is designed to provide means by which made interchangeable that is to say, instantly adapted to any of the various types of mechanical musical instruments now inv general use.

The accompanying drawings will serve to illustrate. a device suitable for carrying my invention into effect. I wish. it understood, however, that I do not limit myself to either the exact construction or arrz'mgoment of parts shown, as various changes may be made therein or the device embodied in other forms operat ng in substantially the same manner to produce practically the same result.

In the drawings, Figure] a view, partly in section, showing a spindle or support for a music-roll of a form suitable for use in an instrument, known as the pianola. Fig. 2 is a sectional view showing the music-roll 01 her type of instrument, known as the angelus. Fig. I, is a view in perspective of the parts or members of the roll-support shown in Fig. 1. Fig. 4 is a similar vicwof the form shown in Fig. 2. Fig. 5 is a erossse(-.tion on the line s s" of Fig. i. Fig. (i isa similar view on'lho line 5 s ol Fig. 2. Fig. 7 is a detail sectional view of the end of the spool upon which the roll is wound. Fig. 8 is a similar 1 1 view showing a slightly-modified construction. Fig. 9 illustrates a further modification thereof. Fig. 10 is a detail sectional view showing the central eyeleted opening of the spool. Fig. 11 is a cross-sectional view thereof; and Fig. 12 is a detail view in perspective, showing a modified form of spindle. v

Referring now to the drawings, the music strip or roll 1 is shown wound upon a spool 2, consisting'oi' a tubular body portion 3, of uniform diameter throughout its length and rovided at its ends with flanges 4, the

ength of the spool between the flanges corresponding approximately with the width of the music strip or roll. i

The body portion 3 of the spool may be .constructed of any suitable material; but heavy paper is preferably employed, a strip of which is wound spirally into tubular form, first in one direction and then in the other, to give the thickness and length required, and is held together by paste. or glue. To the tube thus fornied rings or collars are fitted to serve as the end flanges 4r 4 thereof and may be secured thereon in various waysas shown, for example, in Figs. 7 to 9.

In Fig. 7 the collar is counterbored, as in.- dicated at 5, to receive the end of the tube 3, which is fitted therein and secured by cement, glue, or the like. Interposed between the tube and collar there is a reinforc lug-strip of linen or other fabric 6, which is wound upon the tube and extends a suitable distance inward beyond the flange thereof.

In Fig. .8 the collar is fitted upon the tube flush with the end thereof and secured thus by a reinforcing-band of metal 7, which is fitted in the end of the tube and has teeth or spurs 8 bent up to engage both the tube and the collar thereon.

In Fig. 9 the reinforcing-band 7 and collar 4 are struck up from a sheet-metal disk and secured, as in Fig. 8, by having teeth or spurs S bent up to engage the body of the tube.

The spool is designed as a support or carrier for the ordinary.commercial music strip or roll, which is wound thereon in the usual manner and sold with it. In order now to adapt the roll for use in the different types of mechanical musical instruments now in. general use, I employ in connection with the spool a number of interchangeable spindles 9 9, &cl, which differ one from the other only in having dill'crently-spaced grooves therein, the purpose of which will be later on explained, and ends thereof formed as required to fit the hearings provided in such instrun'ients.

The spindles are preferably constructed of wood tipped with metal, as indicated at 10 10", and are yieldingly held in the tabular body of the spool by a spring-catch 11. A simple form of catch is shown in the drawings, which consists of a piece of spring wire pivoted at 12 in a slot 13 of the spindle and bent up about centrally of its length to provide an engaging projection 14, which enters an opening 15 of the spool. The opening 15 is reinforced with a metal eyelet 16 of suitable form, as shown in Figs. 10 and 11, and the catch is yieldingly held in engagement therewith by having its l'ree end 18 supported upon a pin 19, extending transversely of the slot in the spindle. The engaging projection 14- of thecatch is arranged. in such relation to the ends of the spindle as to center the roll relatively to the trackerboard of the instrument when-engaging the eycleted opening of the spool.

For purposes of illustration .1 have shown two

spindles

9 and 9, one for use in the pianola and the other in the angelus. It will be observed that the spindles are oppositely disposed in the spools, as shown in Figs. 1 and 2that is to say, the end 10 thereof, which interlocks with the rewindingshaft of the instrument, is at the right in Fig. 1, as required in the pianola, and at the left in Fig. 2. as required in'the angelus. This relation is essential in order that the music-strip n'lay unwind from the top of the roll and move in the required direction, as indicated by the arrow, and it is therefore necessary when inserting the spindle in .the

roll to enter it from either the right or left,

depending upon the instrument in which it is to be used. To prevent mistake in this regard, two or more studs or projections 20 are provided at each end within the spool and are differently spar-ed to enter correspondiiigly-spaced grooves 21 formed lcngthwise of each of the spindles. As shown in Figs. 3 and 5, for example, the spacing of the grooves for the ianola--s]rindle is ninety degrees, while that sliown in Figs. 4 and 6 for the angelus-spindle is nearly one hundred and eighty degrees, making it, therefore, in.-

possible to enter a spindle at the wrong end of the roll. It will be evident that various modifications might be employed to ell'ect the same result.

In Fig. 12 .l have shown a slightly-inodilied form of spindle designed to provide for a limited equalizing action when through contraction and expansion of the nnlsie-strip the pull is greater along one edge of the musicstrip than the other. For this purpose the spindle is oppositely tapered from the center toward the ends thereof, and as. a result the spool will have a limited rocking action thereon, permitting the roll to adapt itself to variations in length along opposite sides thereof.

Having thus described my invention, I claim-- I 1. A support for a music-r ll comprising a roll-carrying spool, a remove le spindle supporting the spool, and self-acting locking means interposed between the spool and spindle.
