Application filed April 12, 1912. Serial No. 690,446.
To all whom it may concern Be it known that I, MATTHEW B. CLAUS- SEN, acitizen of the United States of Amerprovements in Talking-Machines, of .which the following is a specification,
My invention relates to improvements on the particular form of attachment to talking machines illustrated and described in my application Serial No. 670,146, filed January 9, 1912, in which is shown a thin sound amplifying disk rigidly mounted on the stylus of the reproducer of a talking machine. In the one particular form of my invention selected for illustration in Said prior application the reproducing needle is clamped into the socket on the end of the stylus arm in the usual way, and the disk is held on the needle by being bored to form an opening of an internal diameter equal to or slightly less than the external diameter of the needle. This requires the needle to be forced through the disk before using, and, as it is notsafe to use a needle on more than one record, it is necessary to pull the needle out of the disk every time a new record is put on, and stick a new needle through the disk before fastening the needle to the stylus arm for the next operation of-the machine. \Vhile this can easily be done with a small pair of tweezers, the entire operation can be avoided by the use of my present invention which comprises means for permanently attaching the disk to the stylus arm, and means for mounting simple device such as a set screw.
the needle in this attaching1neans by any Consequently when a needle is Worn it can be loosened from the disk, removed and a new one fastened to the disk without unfastening the disk from the reproducer.
' The drawing shows a vertical central section of the preferred form of apparatus embodying my invention. i In the construction shown, the disk 8 is made of any material capable of reproducing vibrations similar to sound waves. I have found celluloid to be a convenient material for this purpose, Disk 8, reinforcing disk 11 and hub 9 are forced on to a short bar 12, preferably formed of a hard fiber like bamboo, which may be gripped in the usual socket at the end of the arm which together with the needle 6 forms the stylus 1n the standard type of reproducer. This short bar 12 practically forms an extension of the hub 9. The steel needle 6 is then set diameter, it also becomes possible to use needles of lesser diameter, without materially reducing the rigidity of the joint beiweer the disk and needle. This renders it possible to use the same disk with all sizes of needles while with the form of the invention illustrated in my prior application, a given disk can only be used with that size of needle which can just fit into thebore of the hub and form a rigid connection therewith.
While a soft roundness of tone is given to the sound reproduction by making bar 12 of non-metallic material, metal may be used for the purpose where durability is more important than the quality of the reproduc tion. "While the vibrating sheet of material 8 is usually a circular disk, it may be made of any other convenient form.
Having described my invention, I claim: 1. An attachment for talking machines having the usual form of reproducer, which said attachment com rises a thin freel 1 vibrating sound amplifying disk, said disk having a hub-like projection adapted to engage the stylus arm of the talking machine reproducer and also being provided with a socket for receiving the usual form of reproducer needle, together with means for clamping said needle in said socket.
2. An attachment for talking machines, having the usual form of sound box' and stylus arm, which said attachment comprises a thin, freely vibrating sound amplifying disk provided with a hub having an extension adapted to engage the stylus arm, and which hub is'provided with a socket adapted to receive the usual form of needle, to-
gather with a set screw mounted in said hub, and adapted to engage said needle.
- y '3. Ina. re roducer for talking machines 5"the-o0mbi nat1on of a thin, sound amplifyingsheet' of elastic material, a shortbar 'rigidlyatteehed to the said sheet at one end,
pared out at that: end to reeeive aneedle,
and adapted to be clamped to the st lus arm" of a repro ucer, and a. set screw or hold- 10 ing a needle firmly in the bore of the above mentioned ban.
