PROCESS OF MAKING PHONOGRAMS.
Specification of Letters Patent.
Patented March 10. 1908.
Application filed December 4, 1906. Serial No. 346,299.
To all whom it may concern:
Be it known that I, BITTER P. \VINNE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York. have invented certain new and useful Improvements in Processes ofi Making .lhonogrzuns, of which the following is a specification.
My present invention pertains to an improved phonogram and method of making the same, as will be hereinafter set forth in detail, reference being had to the annexed drawings, wherein:
Figure 1 is a vertical sectional view of one form of apparatus employed in carrying out the process; Fig. 2, a sectional elevationof the com leted phonogram or record; Fig. 3, a simi ar view of the matrix or mold; Fig. 4, sectional elevations of various members of the apparatus; and Fig. 5, a like view of the expanding member employed to force the outer face of the phonogram blank into contact with the matrix.
The main object of the' invention is to produce a superior celluloid phonogram, and
referably one in which the backing memlier for the record surface is molded or given its re uired and finished form at the same time t 1e record is impressed upon the record surface. With the process hereinafter set forth the record may be made relatively (lee which is a point of material advantage.
'l lie honogram in its preferred form may be sai to com rise an outer face or record surface made 0 celluloid, and an inner cylindrical backing or body of pasteboard,
which is molded to form in the process of manufacture.
In carr 'ng out my process, I employ a cylindrica matrix or mold A havin upon its inner face the reverse of the cor to be reproduced, such matrix being of the wellknown form. Within the matrix is placed a cylinder A of relative] thin celluloid, and when the backing is to ,e molded with the record surface, a cylinder or tube B. of pasteboard, the tube making a somewhat rape? or e ore softened by soaking it in water, or in a substance, such as a light paste or glue,'which will soften its fibers and permit it to expand circumferentially without breaking.
Within the pasteboard tube is placed a cylindrical plug or block C of rubber, and the parts thus positioned are placed on end upon a bed or base D from which extends a yoke g or frame.E carrying a screw F. Said screw at its lower end finds its bearing in a socket G formed in the upper face of a pressure-block H, which is seated upon the upper end of the expanding plug or rubber cylinder C, the block likewise extending into a sleeve or collar I which rests upon the matrix and surrounds the upper end of the rubber plug C which normally projects above the upper end of the matrix and its contained blank. A nut J is mounted on the lower end of the in their initial adjustment. When the parts are thus positioned, with the pasteboard backing member softened, heat to the requisite degree to soften the celluloid, is applied to the matrix and pressure exerted upon the block H b r screw F, and through the block to the ru ber plug or expanding member 0. The expansion of the lug is equal in all directions and will force t e connow soft and plastic celluloid cy inder A, the outer face of the latter being forced against and into the matrix, and taking an impression therefrom. After the pressure length of time to effectually re roducc the record upon the celluloid face, t e parts are allowed to cool and the ressure is relieved.
cooling, the celluloid surface will withdraw from contact with the matrix, and the photaken from the matrix. By reason 0 the fact that the backing is pressed or molded to form at the same time the relatively thin celluloid surface has the record impressed upon it, the record surface is evenly sustained and backed up throughout, and no shaping or dressing of the record is requisite. By using an expanding member of the same diameter throughout, an equal pressure is exerted upon the various portions of the softened backingand through it upon the celluloid body which forms the record surface.
It is evident that in so far as the apparatus for making the phonogram is concerned, any form may be employed so long as the cylinplo ed.
Without the backing, in which case the cyinto direct contact with the interior face of Upon the contraction o the parts, due tonogram with its backing or body, ma be drical rubber expanding member is emlindrical rubber expanding member comes screw and is of service in securlng the parts i fined pastcboard tube B directly a ainst the and heat have been maintained a suflicient t is of course possible to form the record No clain'a made an; pew as ilmt 1s zqvplica-uon,
