NEEDLE FOR SOUND-BEPRODUCING MACHINES.
Specification of Letters latent. Patented Apr. 9, 1912.
Application filed September 20, 1911. Serial No. 650,345. 7
To all whom it may concern:
Be it known that I, BENARD TENDLER, a citizen of the United States, residing at Schulenburg, in the county of Fayette and State of Texas, have invented certain new and useful Improvements in Needles for Sound-Reproducing Machines; and 'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable ot-hersskilled in the art to which it appertains to make and use the same.
My invention relates to improvements in needles for soundreproducing machines, and relates more especially to needles used in connection with the gramophone type of reproducing machine.
The object of my invention is to provide a needle which will, when turned for adjustment at various positions within its socket, produce tones of anydesi'red volume.
A further object is to provide a needle which will give a true clear toned reproduction free from ob'jectimial harsh, mechanical noises made by most of the needles now in use. I
The invention will be fully understood in the following detailed description taken in connection with the'accomp'anying drawings forming apart of this application, .in which:
Figure 1 is a side elevation of a socket wit-h one of my needles in place within; Fig. 2 is a side elevation of the needle, on anenlarged scale; Fig. 3 is an edge view of a needle on an enlarged scale; Fig. 4 is a sectional view taken on the line H of Fig. 2; Fig. '5 is a longitudinal sectional view of the needle within the socket; Fig. 6 is a sectional view taken on the line .66 of Fig. 5, and, Fig. 7- is a view similar to Fig. 1 except that the needle is shown in a different position.
Referring to the drawings, there is shown a socket 1 of any desired construction in which is the needle 2, composed of a resilientand hard metal such as steel. One end of the needle is tubular in cross section and forms a hollow shank 3 havin a longitudinal, central bore 4. 'Extending downwardly from the hollow shank 3 are the flat,
are connected at their lower ends by the flat portion 6. By reference to Flg. 3 it will be seen that the thickness of the arms flat portion 6, while as will be seen in Fig. 2, the width of the armsis considerably less than that of the flat portion. The purpose of providing the fiat arms 5 is to allow flexibility of that portion of the needle when pressure is exerted against the edge thereof, while the needle will remain rigidly straight when pressure isapplied to the side or flat portion 6. Centrally of the lower end of the flat portion 6 extends the tapered point 7 of the needle. The point- 7 is not long tapered but is ground extremely sharp; much sharper than the usual form of needle now in use. Between the connecting arms 5 and the flat portion 6 is the elongated slot 8 which communicates with the central bore.
In operation when it is desired to reproduce a record in a loud tone, the needle is placed within the reproducer arm or socket 1 with the edge of the needle slanted to the record as in Fig. 1. Owing to the resiliency of the connecting arms 5 in this direction, the weight of the sound box and its cooperating parts will tend to bend or curve the central portion of the needle toward the record and so directthe pointed end thereof that it bears upon the sound grooves in the record at an acute angle. In this position a part of the thicker portion of the pointedend will engage the side walls of the groove and thereby cause a reproduction of a moderately loud tone.
When a reproduction is desired in a soft, clear tone the needle is placed withinv the socket with the flat portion 6 slanting toward the record as shown in Fig. 7. In this position the needle is held rigidly straight by the arms 5 under the weight of the sound box, and the sharp point of the 5 is substantially the same as that of the 1 elongated resilientconnectmg arms 5, which needle bears directly upon the bottom of the sound groove and thereby causes a reproduction of a moderately soft tone.
What I claim is:
A gramophone needle comprising a hollow shank, a flat portion terminating in a pointed end and elongated parallel connecting arms between said shank and said name to this specification in the presence of flat portion, said arms being spaced to form two subscribing Witnesses. an elongated slot therebetween, sald slot communicating with the bore of said shank, BENARD TENDLER 5 said arms being capable of being bent VVitnesses:
