RECORD-ROLL FOR SPHONOGRAPHS.

To @ZZ whom it-may'conce'wi Be itlmown that we, CYRUs C. SHIGLEY and SHERMAN H. PAXTON, citizens of the United States, residing at the village of Hart, county of Oceana, State of Michigan, have invented `certain new and useful Improvements in Record-Rolls for Phonographs, of which the following is a specification. p

This invention relates to improvements in -record-rolls for phonographs.

by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features, of our invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in whichl Figure l is a central longitudinal sectional view through our improved phonograph record-roll, the mandrel-shaft E being shown in full lines. Fig. 2 is a detail cross-sectional view of the structure appearing .in Fig. 1. Fig. 3 is a side elevation view of the mand relsleeve. Fig. l is anend elevation view of the mandrel-sleeve D looking from the right of Fig. 3.

In the drawings similar letters of reference refer to similar parts throughout the several Views.

`Referring to the drawings, the cylindrical shell A is formed of celluloid or other suitable composition adapted to receive and retain a phonographic record. This shell A is n, comparatively thin and is preferably provided with inturned flanges at each end. The shell A is provided with a backing B, of some suitable plastic material, preferably plaster- Specification of Letters Patent.r v Application filed November 9,1903. Serial No. 180,450.

sleeve D is slitted at one end, as at al, and is crimped to causeit to grip upon the mandrel or shaft E', which is of even diameter from end to end, except that it is provided with v suitable bearing-pivots at each end.

` Our improved phonograph record-roll is particularly adapted for use on phonographmachines, such as is illustrated in Letters Patent of Cyrus C. Shigley, issued May 5, 1903, No.'727,'002. The same is, however, adapted for use in other machines.

In assembling our improved record-roll the record is first made upon the shell A. The mandrel-sleeve is then placed in the core C and the shell suitably centered about the same. The plastic backing material B is then poured or cast about the core. This secures the core and the mandrel-sleeve in position,

and forms a backing v for the thin shell A, which is solid and uniform.

' Plaster-of-paris is, as before stated, preferably used for the backing B.l This material may be readily poured and is comparatively light in weight. The core C isA preferably made of wood, although other materials, such as ber, may be used and satisfactory results be secured.

Our improved record-roll is very econom ical to produce and is durable in use.

We have illustrated and described our improved phonographic record-roll in det-ail in same specifically as illustrated. as well as broadly'.

Having thus described our invention, what we claim as new, Vand desire to secure by Letters Patent, is-

1. In a phonographic record, the combination of an outer shell of celluloid or other suitable material having inturned Hanges at its ends; a mandrel-sleeve having one end thereof crimpedl and slitted; a core of wood or other suitable material on said mandrelsleeve; a suitable plastic material molded or cast within said shell about said core; and a mandrel-shaft E, all coacting forthe purpose specied. Y

2. In a phonographic record, the combination of an outer shell of celluloid or other suitable material; la mandrel-sleeve having one end thereof crimped and slitted; a core of Wood or other suitable material on said mandrel-sleeve; a suitable plastic material molded or cast within said shell about said core; and a mandrel-shaft E; all eoaeting for the purpose specified.

3. In a phonographie record, the combination of an outer shell of Celluloid or other Suitable material having` inturned flanges at its ends; a mandrel-sleeve; a core ot' wood or other suitable material on said mandrel-sleeve; and a suitable plastic material molded or cast Within said shell about said core, all eoacting for the purpose specied.

4c. In a phonographic record, the combination of an outer shell of celluloid or other suitable material; amandrel-sleeve; a core of Wood or other suitable material on said mandrel-sleeve; and a suitable plastic material molded or east Within said shell about said core, all coaeting for the purpose specified.

5. In a phonographic record, the combination et' an outer shell of celluloid or other suitable material having inturned flanges at its ends; a suitable core adapted to receive a mandrel therethrough Centrally arranged in said shell; and a plastic material molded or cast Within said shell about said core, for the purpose specified.

6. In a phonographic record. the combination of an outer shell of celluloid or other suitable material; a suitable core adapted to receive a mandrel therethrough centrally arranged in said shell; and a plastic material molded or cast within said shell about said core, for the purpose specilied.

In Witness whereofl we have hereunto set our hands in the presence of two witnesses.
