Feb. 4, 1930. R. J. MARSHALL MOUNTING FOR PHONOGRAPHIC PICK-UP DEVICES Filed March 8, 1929 TOR N N H %/ZLM ATI'ORN Patented Feb. 4, 1930 UNITED STATES PATENT OFFICE ROBERT J. MARSHALL, OF ELMHURST, NEW YORK, ASSIGNOR TO NORTH AMERICAN SOUND AND TALKING PICTURE EQUIPMENT CORPORATION, OF NEW YORK, N. Y., A
CORPORATION OF DELAWARE MOUNTING FOR PHONOGRAPHIC PICK-UP DEVICES Application filed March 8, 1929. Serial No. 345,253.
The present invention relates to improvements in devices for recording and reproducing sound for use in connection with apparatus for recording and reproducing moving pictures. More particularly it relates to the mounting of the pick-up recording device associated with the phonograph record.
It is now common to provide a resilient connection between the turntable standard and the base upon which the turntable is mounted, for the purpose of insulating the standard against vibration from the driving motor and other sources of vibration which would have an adverse effect on the tonal quality of the sound reproduced or recorded.
In accordance with my present invention, I mount the pick-up or recording device upon a standard attached to the turntable standard whereby I avoid having either to rest the support for the pick-up device upon a member apart from the table bearing the turntable standard or to provide separate insulating means between such standard and the main table.
Myinvention will be clearly understood from the following detailed description taken with the annexed drawing, in which the figure shows an illustrative embodiment of my invention.
In said drawing, 10 denotes a table to which is attached a phonographic turntable 15 by means of bolts 12, 1 2, a plurality of felt washers 14 being interposed between said standard and table as shown, such washers being effective to insulate the standard 11 from vibrations acquired by the table 10 from the motor, not shown, for driving the turntable. The turntable proper denoted by 15 on felt rings 28, 28 to receive which are provided recesses 29, 29 in the worm-wheel 22. A collar 30 secured to shaft 27 by set screw 31 is provided at the top of the worm-wheel, said collar 30 and collar 24 being separated from the worm-wheel 22 by means of felt washers 83, 84. In this manner a completely floating construction is provided for the worm-wheel 22 which effectively prevents vibrations from said wheel from being transmitted to the turntable 15.
Attached to one leg of standard 11 is an arm 35, said arm being secured thereto by means of bolts 36, 36. Arm 35 has a platform 38 adapted to receive the pick-up or recording device 39 which is operatively associated with the phonograph record 40, said device being joined to said platform as by a screw bolt 11.
It will be evident from the foregoing that I have provided a means for mounting the pick-up or recording device such that said device is effectively insulated from vibrations reaching same while making use of no other vibration insulating devices other than those necessary to the insulation'of the turntable shaft.
- I claim:
1. A device of the character described, a phonographic turntable comprising a standard, a support for said standard, means attaching same to said support, means for insulating said standard against vibration from said support, a sound recording or reproduc ing device adapted to be operatively associated with a record borne by said turntable, and a standard bearing said sound device attached to said turntable standard.
2. In a device of the character described, a phonographic turntable comprising a standard, a support therefor, means for driving said turntable, means attaching said turntable to said support, means for insulating said standard against vibration from said support, means for insulating said standard against vibration through said driving means, and a standard bearing said sound device attached to said standard of said turntable.
3. In combination with a phonographic turntable comprising a standard and having means for insulating said turntable from vibration afiectin sound which is either recorded or repr said turntable, a sound recording or reproducin device adapted to be operatively associate with a record borne by said turn table, afiil a. standard bearing said" device which is supported solely by said turntable standard.
In testimony whereof I have afiixed m I signature to this specification.
