w. s. TYLER & F. L. CAPPS. MATRIX FOR PRESSING SOUND RECORDS.
APPLICATION FILED JULY 15,1913- Patented Aug. 15, 1916 pressing sound-records.
WALTER S. TYLER AND FRANK L. CAPPS, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR S TO AMERICAN GBAPHOPHONE COMPANY, OF BEIDGEPOBT, CONNECTICUT, A COR-P0" RATION' OF WEST VIRGINIA.
MATRIX FOB. PRESSING SOUND-RECORDS.
To (125 whom it may concern:
Be it known that we, WALTER S. TYLER and FRANK L. CArrs, of Bridgeport, Connecticut, have invented a new and. useful Improvement in Matrices for Pressing Sound-Records, which invention is fully set forth in the following specification.
This invention relates to matrices for Such matrices are usually formed by electrolytically depositing a thin copper shell upon the original sound-record formed in wax or wax-like material, separating the thincopper shell from the original record, and backing or strengthening it by sweating it onto a thicker body of metal, such as copper. The matrix thus prepared is in the form of a circular disk, with an opening at its center, which opening is known as the centering opening, and which is a necessary feature when using the matrix to press sound-records therewith. These matrices are used over and over a large number of times, and it has been found in practice that, in placing the central opening of the matrix over the centering pin in the process of pressing a record, the thin copper shell in time is liable to peel up or become separated from the metal backing, thus producing in the record that is pressed from such a matrix an unsightly finish around the centering opening.
The object of the present invention is to overcome this difiiculty, and with the same object in view, the invention consists in the means and combination of elements hereinafter described and then specifically defined in the claims. r
The inventive idea is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustrating the invention, is shownin the accompanying drawing, but such drawing is for the purpose of illustration only, and is not meant to define thelimits of the invention, reference being had to the claims for this purpose.
In said drawings, Figure l is a central vertical section, and Fig. 2 is a broken plan view.
Referring to the drawings, in which like reference characters indicate like parts, 1 is the electroplate or shell and 2 is the backing of metal or other suitable material, onto Specification of Letters Patent.

" Application filed July 15, 1913. Serial No. 779,172.
1 which the copper shell 1 is sweated in the usual or any suitable manner.
3 is the central opening through the metal backing, and 4: v a corresponding central opening through the shell 1. An annular recess 5 is formed in the rear or under side of the backing: 2. and around the opening 3,
and an eyelet G, of any suitable material,
such as brass, and having an annular flange 7 proportioned to fit the annular recess 5, is inserted through the opening 3, the eyelet belng so proportioned as to make a tight fit 1n the openings 3 and 4:, and when so inserted the eyelet is of the form shown in dotted lines in the drawing, the end 8 of the eyelet projecting upthrough the opening 4; in the shell 1 for a suitable distance, as shown in dotted lines in the drawing. This upwardly projecting end of the eyelet is then turned over and outward, by means of a suitable die, until it contacts with the upper surface of the shell 1, as shown at 9 in the drawing, thereby forming an annular bead 1O surrounding the opening in the matrix. Any other suitable form may be given to the overturned end 8 of the eyelet, but the bead shown is a desirable form, producing a small annular groove around the central opening in the record when the same is pressed from the matrix.
By the means shown, all the battering and wear incident to the use of the matrix is taken by the eyelet, and in case the same becomes damaged, it may be readily removed and another one inserted in its stead, thus avoiding the necessity of returning the matrix to the work-shop for repairs and for resweating the shell 1 to the backing '2. This latter operation consumes considerable time, during which the matrix is out of commission, whereas the eyelet forming the present invention can be removed, and a new one substituted, in a very few moments.
Having thus described our invention, what is claimed is:
1. In a matrix for pressing sound-records, the combination of the shell or matrix surface proper and the backing therefor, each of which is provided with a central opening therethrough, with an eyelet extending through and fitting said opening, and having one flanged shoulder engaging the rear of the backing,
3. Inza matrix for pressing sound-records, the combination of a metal shell forming the face proper of the matrix, a metal backing therefor, said shell and backing being pro' vided with a centering opening therethrough, and an eyelet fitting snugly in said opening and provided with an outwardly I g, and an outwardly turned annularbeadengaging the front face of said shell.
tllliled upset {shoulder for engaging the she I.
4. In a matrix for pressing sound-records, the combination of a metal shell forming the face proper of the matrix,.a metal backing sweated thereto, said shell and backing each being provided with a centering opening theretlirough, an eyelet fitting in said opening and having a flange engaging the rear of the backing and an outwardly turnedupset annular bead engaging the front face of said shell. 4 f
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
