WIND IYNG=RO LLER FOR MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 271,064, dated January 23, 183.

Application filed December 22, 1881. No model.) i

To all whom it may concern:

Be it known that 1, ANDREW H. HAMMOND, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in VVinding- Rollers for Mechanical Musical Instruments, of which the following is a specification.

The object of my present improvements is to produce a roller on which a traveling musicsheet fora mechanical musical instrument may be wound, and which shall be so light as to acquire but little momentum when in motion. Such a roller is especially desirable as a takeup roller for the music-sheet.-

My improvements consist in the combination, in ainechanical musical instrument, with a traveling music-sheet, ot' a roller composed ofa wooden or other shaft and heads, and a body consisting of a cylindric shell, of paper or other light material.

They also consist in the combination, with such a music-sheet, ot' a roller composed of a wooden or other shaft provided with two heads and an intermediate flange or truck, and a body consisting of a cylindric shell, of paper or other light material, and having a peripberical recess containing a device whereby the sheet may be attached.

In the accompanying drawings, Figure 1' representsa longitudinal section of a mechanical musical instrument containing rollers embodying myim provements, Fig. 2 is a top view of the case and rollers of the same, one of the rollers being partly in section; and Fig. 3 is a longitudinal section of the case of the instrument, a side view of bearings for the rollers, and a transverse section of journals of the rollers in the bearings. I

Similar letters of reference designate corresponding parts in all the figures.

A designates the case of a mechanical musical instrument. B designates the reed-board thereof. 0 designates the traveling perforated IDUSICSIIGGT. D designates the roller on which the music-sheet is normally kept wound, and E designates the take-up roller on which the music-sheet is wound during the playing of the instrument.

The take-up roller E consists of a shaft, a, of wood or other suitable material, two heads,

b, affixed thereto, hubs c, contiguous to the heads, and preferably made integral therewith, an intermediate flange or truck, cl, and a cylindric body or drum, 6, of paper or other light material, fitting the said hubs and flange 5 or truck.

In the periphery of the flange or truck cl and adjacent part of the body or drum 0 is a recess, f, provided near the bottom with a hook, g, for detachablysecuring the musicsheet thereto. The end of the music-sheet is preferably provided with a ring, h, capable of engagement with the book 9, and this ring may be secured to the music-sheet by a tape or strip, of any strong thin material, passing 6 through the ring, and lapped over each side of and secured by paste, glue, or otherwise to the music-sheet.

I prefer to make the heads of the musicroller 1) of paper, binders board, leather- 70.

board, or like material, for in that way I can easily and cheaply make them strong and durable. They project circumferentially beyond the body of the roller. One or both the heads of the take-up roller E may be made in the same manner, if desirable.

The headset the rollers used in mechanical musical instruments and certain other articles are necessarily so thin that when made of wood they are easily split and broken; but by making them of paper, binders board, leatherboard, or like material this difficulty is obviated. Where used they are pressed onto 8X- tensions of the shalt or body of the rollers,

made of less diameter than the shafts or bodies themselves, and glued against the shoulders thus formed. Motion may be transmitted to these rollers by any suitable means acting on the heads of the rollers, or otherwise.

These music and take-up rollers are show-n 0 beyond the notches j, thus enabling a rollerjournal to be placed between such diverging portions, and then inserted in the notch by In the edge'of the blocks I are 5 g 2 QWMMML simply pushing it down or into it, the cap I combination,\vith a traveling music-sheet, of

being forced away from the block I by the pressure exerted upon it by the journal, and after the entrance ot'the journal into the notch returning to hold the journal in the notch. The caps I of these bearings bear directly on the journals ofthe rollers and exert friction thereon, which will prevent the rollers from moving too rapidly, or from moving at all when they are not desired to move.

When a roller is to be removed it has only to be pulled-outward with a little force, and hence it will be seen that the roller may be either inserted or removed without any ncccssity for manipulating the bearings.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a mechanical musical instrument, the

a roller composed of a; wooden or other shaft and heads, and a body consisting of a cylindric shell, ofpaper or other light material, substantially as specified.

2. Ina mechanical musical instrument, the combination, with a traveling music-sheet, of a roller composed of a wooden or other shaft, provided with two heads and an intermediate flange or truck, and a body consisting of a ctlindric shell, of paper or other light material, and having a peripherical recess containing a device for the attachment of said music-sheet, substantially as specified. v
