PHONOGRAPH RECORD AND METHOD OF MAKING THE sum.

Application fled April 82, 1926- Serial I0. 103,758.

My invention relates to improvements in phonograph records of the disk type and has for one of its objects a raised outer run which has a. commercial advantage in that the needle, if placed upon the smooth surface of the rim when starting to play the record, will automatically run down said smooth surface and enter the record groove.

Another object of my inventlon 1s to prol0 vide a disk type phono raph record with a raised outer rim whic will prevent the threads of the spiral record groove from becoming marred when they are placed upon one another.

Another object of my invention is to provide a knurled edge upon the outer periphery of the record which affords a firmer grip when removin the record from the phonograph turn ta le or when takin it out of the record compartment of the p onograph cabinet.

Duringthe process of manufactur ng my improved disk record, the fin, WlllCl'l 1s ordinarily present on records when taken from 26 the presses has been replaced by the knurled edge. This elimination of the fin results in economies of manufacture because the ed ing rocess required to remove it results in breakage and marring of records, and also 30 permits the records to be moved directly from the presses to the inspectlon department. The absence of the fin also makes it possible to accurately determine the weight of the record so that the correct amount of material required to form it can be injected into the dies, eliminating the ossibility of producing underweight recor s which are easily broken in transit or handling, or the production of overweight records which represent a loss in material. Y

With these and other objects in view, to be more fully set forth hereinafter, the invention consists in the novel construction, combination of elements and arrangement of parts which will be exemplified in the construction herein described in the following specification and illustrated in the accompanying drawings.

The invention will first be described in connection with the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views, and more specifically defined and indicated in the appended claims.

Attention is directed to t e drawings in which:

Fig. 1 is a partial proved disk record;

Fig. 2 is a sectional view of same looking in the direction of the arrows 2-2;

Fig. 3 is an enlarged partial sectional view illustrating the raised rim and lmurled edge;

Fig. 4 is an enlarged view illustrating a portion of the knurled edge; and

Fig. 5 is an enlarged partial sectional view illustrating how the record grooves are prevented from becoming marred when placed upon one another.

Referring tothe drawings, numeral 1 re resents the record, 2 the usual hole in t e center of the record for centering it upon the turn-table of the phonograph, and 3 the usual spiral record groove. The edge or rim 4 is of greater thickness than that portion of the record into which the record groove is pressed; its smooth surfaces or faces, starting at the beginning of the record groove, diverging outward at a slight angle to the periphery as illustrated in Figs. 2, 3 and 6. A reproducer partially represented by dot and dash lines, when placed upon the highest point of the rim as illustrated at R, will take the position illustrated R when the record starts to revolve. This inward swing causes the needle to enter the groove immediately, thereby eliminating the usual numerous attempts to find the groove, and making it possible to start playing my improved record in total darkness. The rim 4 also protects the, record groove from becoming marred. This is due to the thickness of the rim which prevents the record grooves from coming into contact with each other or with a table top when placed upon it as illustrated in Fig. 6. The knurled edge 5 of the rim 4 afiords several advantages which are as follows: First, it can be easily picked up when lying upon a flat surface, the particular formation of the knurling allowing the finger F of the operator to et a firmer grip as illustrated in Fi 3. be second advantage of the knurled edge is that it eliminates the usual fin which forms upon the record when it is molded, the excess material being taken up in the knurling.

In accordance with the provisions of the plan view of my impatent statute, I have described my invention, but I desire it understood that my invention is not confined to the particular form shown and described, the same being merely illustrative, and that the invent1on can be carried out in other ways without departing from the spirit of m invention, and therefore, I claim broadly t e r1 ht to emloy all equivalent instruments ities commg within the scope of the appended claims, and by means of which, ob ects of my invention are attained, and new results accomplished; as it is obvious that the particular embodiments herein shown and descrlbed are only some of many that can be em loyed to attain these objects and accomplish these results.

\Vhat I claim and desire to obtain by Letters Patent is v 1. A phonograph record of the character described having an enlarged IlIIl with a knurled transverse edge.

2. A phonograph record of the character described having a rim of greater thickness than that portion of said record into wh ch the record groove is pressed said rim having a knurled transverse edge.

3. A phonograph record of the character described having an enlarged rim w1th a knurled transverse edge, the faces of said rim starting at the beginning of the record groove.

4. A phonograph record of the character described having a rim with a knurled transverse edge and of greater thickness than that ortion of the record into which the record groove is pressed, the faces of said rim starting at the beginning of the record groove.

5. The method of making a disk sound record consisting in knurling the edge of the record during the operation of forming a sound groove in the record body.

6. The method of making a disk sound record consisting in knurling the transverse edge of the record.

7. The method of making a disk sound record consisting in knurling thetransverse edge of the record during the operation of forming a sound groove in the record.

8. As a new article of manufacture, a disk sound record having its transverse edge knurled.

9. A ste in the manufacture of making a disk soun record consisting in ressing a design into the edge of the record body.

10. The method of finishing the edge of a disk sound record consisting in molding a design in said edge.

11. As a new article of manufacture, a disk sound record having a design formed in its transverse peripheral edge.
