SOUND Application filed September This invention relates to sound records and more particularly to phonograph disc records made of a thin flexible material, as distinguished from the present day type of record which is of substantial thickness and rigidity.

An object of the invention is to eliminate the troubles incident to the use of a thin flexible record such as those made of sheet celluloid and which has a tendency to split open '10 at the center hole, particularly when the spindle of the phonograph is slightly larger than the hole of the record, as is sometimes the case.

Another object of the invention is to provide means for providing a grip between the record and the turn table spindle to prevent possible movement of the record on the turn ta le.

A further object is to effectively prevent any splitting or tearing action of the record, as it is forced over the turn table spindle, from going beyond a predetermined point.

Finally, an object is to reinforce the central section of a record of this type, while yet providing a central hole of variable diameter adapted to make the record fit over turn table spindles of varying sizes.

All these and other objects as hereinbelow suggested are obtained in the structure now to be described, and illustrated in the accompanying drawing, in which- Figure 1 is a side-elevational fragmentary view of a phonograph record embodying the feature covered by this invention; and

Fig. 2, a cross-sectional viewthereof taken through the plane 22 of Fig. 1.

Like numerals refer to like parts throughout the several views.

The record is preferably made of thin 40 sheet celluloid, or other flexible material, and comprises the usual blank outer rim 10, a sound-record groove section 11, a title label 12, and a center hole 13.

A plurality of slits 14 is cut entirely through the record, and extending outwardly from the center hole 13 and preferably radially located, as shown.

Surrounding the ends of slits 14 is a circular raised section 15 embossed upwardly from the material itself and which serves on NEW YORK, N.

not only to strengthen the central section of the thin record, but also to prevent slits 14 from tearing out at their ends across the record, it having been found that this is an effective means of accomplishing this result.

'The label 12 is shown as having an enlarged central hole sov that its inner edge surrounds the reinforcing circle 15. However, instead of this construction, the label might well extend to the edge of the center hole 13 and be embossed and slit through with the flexible record material to which it is impressed.

In use the portions of the record between the various slits 14 bend upwardly when the 7,65

record is pressed down over the phonograph turn table spindle, particularly where the spindle is slightly larger in diameter than the record hole. This gives an eifective grip between the two, and the repeated applying .7 and removing of the record from the phonograph (and which would normally tend to extend the length of the slit by tearing) is prevented from so doing by the embossed circle 15, which also makes the center section of the record rigid and easy to apply to the turn table.

It is to be understood that the present disclosure is for the purpose of illustration only, and that the invention is not limited thGI'GtO.; -g0 To those skilled in the art, many modifications of the invention will be readily apparent, and it will also be obvious tosuch skilled persons that parts of the device and method may be used without other parts thereof,-.- 5 I many such combinations readily suggesting themselves. Therefore, it should be, and is to be distinctly understood that for a definition of the limitations of the invention, reference must be had to the appended claims.

Having now described the invention what is claimed as new and for which Letters Patent of the United States is desired, is:

1. The combination in a flexible phonograph record of resilient means on the record;; engaging the phonograph turn table spindle to prevent relative movement between the. two when in use.

2. A flexible phonograph record having a center hole slightly smaller than the turn doo table spindle to which it is to be applied, and a plurality of radiating slits adapted to increase the effective diameter of the hole to make it fit over spindles of different sizes.

3. A phonograph record including a center hole, a plurality of slits radiating therefrom and a surrounding embossed section adapted to prevent tearing at the slits and also to reinforce the center section of the I record.

4. The invention as in claim 3, there being a label surrounding the embossed section.

Signed at New York, in the county of New York, and State of New York, this 14th day of September, A. D. 1928.
