PHONOGRAPH RECORD Filed Oct. 10, 1950 2 Sheets-Sheet 2 INVENTOR t Arl/zurMAw/wwon M ATTORNEY Patented Sept. 22, 1931 UNITED STATES, PATENT OFFICE ARTHUR M. ACHESON, OF DOBBS FERRY, NEW YORK, ASSIGNOR '10 DUBIUM PRODUCTS CORPORATION, OF NEW YORK, N. Y., A. CORPORATION OF DELAWARE rnonoenarn nncoan Application am October 10, 19:30. Serial No. 487,713.

- The present invention relates broadly to phonograph records, and more especially to a record table pin holder for a flexlble phonograph record.

Flexible phonograph records made on a paper stock of substantiallycardboard thickness may have a tendency 1n repeated use to enlarge the record table pin opening due to wear, so that the record may leave the record turntable while the record is be ng played.

The present invention overcomes the d fiiculties above outlined b provrdmg fr ctlon members passing throng the pm opening in the record and being adapted to engage with the sides of the pin on the record table of a phonograph.

The present .lIlVGIltlOIl 1n lts preferred form comprises the interlaclng of a live rubber band through the phonograph record adjacent the in opening in such manner that the record talile pm engages with the rubber bands, thereby relieving the sides of the pin opening of the friction necessary to hold the record 'in position on the record turntable.

The-rubber bands may either pass through the pin opening or be arranged 1n such mannerthat a portion of the rubber bands extend across the said opening so that the rubber bands form the major contact with the sides of the pin to hold the record in place on the table.

It is to be understood that the present invention may be practiced in constructions differing from the disclosure herewith and, therefore, the said disclosure is to be considered as illustrative and not in the limiting sense.

Fig. 1 illustrates a'plan view of the preferred form of the present invention.

of Fig. 5.

Fig. 7 is a plan .view of another modification of the present invention.

Fig 8 is an enlarged sectional view on lines 8-8 of Fig. 7.

Referring now to the drawings and more especially to Figs. 1 and 2, a flexible phonograph record body 1 is provided with a pin ted lines in Fig. '2) is forced through the pin opening 2, these rubber bands are slightly compressed so as to form friction members engaging the side Walls of the pin 7 which thereby. holds the record fiat on' the table without any danger of the record tending to ride up over the pin 7. Repeated use of the record brings the wear from the pin on the portions of the rubber band 6 which have a relatively long life and consequently, the record may be used for avery' long period of time without substantial enlargement of the pin openin and in this way effectually hold the reco i'il inposition while it is being played.

Figs. 3 and 4 illustrate a modification of the invention in which individual sections 8 of rubber bands are locked in position to extend through the pin opening 2 by forcing one end 9 of the rubber bands through a narrow slit in the record body and forcing the other end 10 ofthe rubber bands through an adjacent narrow slit, thereby forming a 10p 11,' a portion of which extends through the pin opening in such manner as to provide portions 12 which preferably are located 120 apart around the pin opening to engage the sides of the pin. The-slits'in the record body are preferably less in width than the thickness of the band so that after the ends have been forced through the slits the expansion of the rubber an'chorsthe ends in place. Fig. 6 is an enlarged view on llnes 66 Figs. 5 and 6 illustrate another form 01 the invention in which rubber bands 14 exarrangement around the pin opening 2, and

whereby the bands from the said openings 18 extend through the pin opening 2 in a diagonal relation to provide friction members which will engage the turntable pin and thus hold the record in position on the table while the record is being played.

From the foregoing, it will be observed that the several forms of the present invention each provide resilient live rubber contact means, preferably from a live rubber band arrangement, which rubber is adapted to cooperate with the record table pin to hold the record inposition while playing, and at the same time obviate the difliculties which arise in case the pin opening in the record tends to Wear.

The several rubber bands preferably, though not necessarily, are under slight tension in order to cause the bands to lay flat on the side of the phonograph record.

Having described my invention, 1 claim:

1. A phonographrecord of the disc type provided with a pin opening located in the center thereof, and friction bands extending through said opening and anchored to said phonograph record.

2. A phonograph record of the disc type provided with a pin opening in' the center thereof, and a plurality of flexible rubber bands extending through said pin opening to comprise a friction member adapted to engage the pin of a record table.

table pin when said phonograph record is in playing position on the record table.

6. A phonograph record of the flat disc type provided with a central pinopening, and a plurality of rubber bands carried by said phonograph record and having ortions of said bands nearer to the center 0 the record than the side walls of said opening whereby said bands contact with a record table to retain said record in place on a record turntable when the record is in' use.

7. A phonograph record of the flexible disc type provided with a pin opening and a plurality of rubber band members mounted on both sides of said record and adapted to contact with a record table pin when said record is in playing position on the record table.

8. A phonograph record of the flexible disc type having a centrally located pin opening, and a plurality of resilient bands carried by said record and adapted to comprise friction members to engage a record turntable pin to retain said record in position on said turntable when said record is in use.

ARTHUR M. ACHESON.

3. A phonograph record of the flexible disc 1 type comprising a circular body provided with a central pin opening therein, and a plurality of flexible bands anchored to said record and extending over a portion of said pin opening whereby said bands are adapted to engage a record table pin to retain said record in place on said table when said record is in use. A i d I 4. A phonograph record of the flexible disc type provided with a centrally located pin opening, and a plurality of looped resilient rubber bands looped-through said opening to comprise resilient friction members.

5. A phonograph record of the disc type having a centrally located pin opening, and a plurality of rubber bands under tension anchored to said re'eord and havinga portion thereof positioned relative to said opening in such manner as to engage the side of a record Ill
