'GUNNARD P. PETERSON, OF NAUGA'IUCK, CONNECTICUT, ASSIGNOR TO THE RISDO'N MANUFACTURING COMPANY. OF NAUGATUCK, CONNECTICUT, A CORPORATION OF CONNECTICUT.

REEL.

Application filed March 16, 1922. Serial No. 544,103.

T Z whom it may concern lie it known that I. GUNN.-\RD P. PETER- sox. a citizen of the United States. residing. in Naugatuck, Connecticut, have invented the following described Improvements in Ree s.

My invention relates to the spools or reels for the paper records of player-pianos and like uses and its object is to provide inexpensive end pieces for such reels that are extremely durable in use and practically proof against disfigurement from accidental causes. as for example, the dropping of the reel when loaded with a heavy paper record.

In the accompanying drawing. Fig. 1 shows a reel embodying my invention. the end pieces being in section. Figs. 2. 3 and 4 show the separated parts of an end piece. Fig. 5 shows the same parts assembled and in elevation. and Fig. 6 shows a modification.

The reel shown in Fig. 1 comprises a cy-- 'lindrical body of wood or composition, made tubular or recessed at its ends for attachment to the hubs of the end pieces, which are marked 2 and 3. and which are identical in structure except that the piece 3 at the left; hand end is provided with a driving slot 6 while the other has no such slot.

Their function is to provide the flanges at the ends of the reel to guide and protect the paper record wound on the body and also to provide the bearing seats or journal means by which the reel is supported for rotation in the piano. Each of these end pieces 2 and 3 comprises metal end members and a body or filler of a moldable material made of or having a base of rubber shoddy, but any other material which is moderately rigid and preferably somewhat elastic when molded and not easily fractured may be substituted. In the preferred form, two separate outside metal members 9 and 10 provide an enclosing metal casing and are crimped or otherwise united about the body or filler member 11. In the construction illustrated. the memher 9 forms the surface of the inner side cured to the margin of the member 9 and is appropriately configured to form therewith an end piece of the size and thickness usual in music roll ends. Preferably each face member 10 is formed with a central depression or socket 5, the end Wall of which in the driving piece 3, is slotted at 6, to receive the driving key of the piano. Both metal members 9 and 10 may be stamped from flat sheet metal stock, and are joined together in Figs. 1 to 5 by their oppositely disposed flanges 15 and 16, one of which, 16, fits within the other, 15, which is spun or crimped over it: obviously, however, this construction of the metal casing is subject to modification.- The filler 11 as already stated, consists of a moldable plastic material and is designed to afford the strength and body required for the end piece While the outside pie'cesprovide the metal or other hard wearing-surfaces and bearings. The filler more or less fills and thereby reinforces the metal enclosure. in the instance shown, extending fully to the circumference of the flange portion of the reel end and more or less into the hub 13, and also conforming to the contour of the casing members and thus permanently spacing and bracing the metal walls to prevent their being dented or crushed. As before stated, I have found a compound having a rubber shoddy base, that is 'to say, a compound composed largely of rubber shoddy to' be both eflective and inexpensive and if desired, this .filler is substantially proof against-becoming loose and rattling. The centers of all the fillers 11 are recessed deeper than the depressions 5 to allow the necessary penetration of the driving key into the slot 6 of thedriving end piece; one size and shape of filler therefore serves for both ends.

In Fig. 6, the rim of the member v9 is pressed inwardly, as shown. and the edge of the member 10 is turned into this annulargroove which is preferably asdeep as, or a little deeper than the thickness of the metal of the member 10, so that the edge of the latter is out of the Way of the paper record as the latter is run on and off the reel. The filler 11, compressed between the members 9 and 10 (particularly at the bottom of the inner convolutions 18 in the resent instance), maintains the edges 0 the metal members in contact elastically and hence prevents the loosening of the joint.

Claims: I

1. A player-piano reel end-piece comprising a metal casing and a body of a plastic moldable material confined therein.

2. A player-piano reel comprising a cylindrical body and flanged end pieces therefor each comprising a thin sheet-metal casing and a filler of a plastic moldable compound. v

3. A player-piano reel end-piece comprising a thin metal hub member, a thin metal face member joined thereto, and a filler and spacer consisting of a body of permanently plastic moldable material.

4. A player-piano reel end-piece comrising a thin metal casing consisting of a ub portion and a faceportion joined thereto, and a filler and spacer consisting of a rubber-base plastic moldable compound.

5. A player-piano reel end-piece comprising a thin metal casing consisting of a hub member and a face member, the edge of one member being turned over the edge of the other to join the members, and an elastic filler and spacer compressed between said members and compensating for loosenessat the joint.

6. A player-piano reel end-piece com-. prising a thin metal casing consisting of a hub member and a face member, one of said members having an and the edge f one of said members being turned over t e edge of the other to join the members, and an elastic filler and spacer contained between said hub and face members and compressed between the bottom of said convolution and the other of the two members to maintain the join between the two members tight and compensate for lo'oseness at said join.

In testimony whereof, I have signed this specification.

GUNNARD P. PETERSON.
