NEEDLE Filed July 15, 1927 INVENTOR Patented June 11, 1929.
UNITED STATES RICHARD zwna'o'r' LA onmanounonas.
NEEDLE.
Application filed July 15,
This invention relates to sound producers for phonographs.
As is well known all phonograph styli made of vegetable fiber or the like have the 5 property of reproducing a phonograph record without distortion, but the volume of sound is less than when the stylus is made of tungsten, steel, or the like.
\Vith that heretofore recited in view, it is 10 the prime purpose of the present invention to produce a -'device including a stylus for "phonographs, that will retain all the desirable qualities of a fiber stylus, but reproduce a record with substantially the same volume as a steel or other metallic form of stylus.
To a-mplify'the sound vibrations given by a record through a fiber stylus it is neces sary to produce such amplification between the stylus and sound box of the phonograph. I accomplish this by interposing a sound vessel or sound capsule between the stylus and sound box. The sound vessel has very high acoustic properties, viz, the walls of the vessel are very thin and made of brass or the like. Also to augment the elasticity of the vessel, the pressure within the vessel differs from the pressure existing outside thereof.
It is a further object of the invention that the stylus is adapted to be adjusted for change in the volume produced thereby.
It is also within the scope of the objects of the invention that the stylus and sound amplifying means therefor is durable and inexpensive to manufacture.
Other objects and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.
The invention is illustrated by way of 40 example in the accompanying drawings, in
which: 7
Figure 1 is a fragmentary perspective view illustrating my invention applied to a phonop Figure 2 is a group View showing in perspective the parts of my device,
Figure 3 is a central longitudinal sectional view of the device illustrating how the same r may be adjusted for sound volume.
Figure 4: is a detail bottom view of the cap for the sound amplifying bar or capsule, and
Figure 5 is a view similar to Figure 3, but showing a modified form of stylus.
Referring to the drawings more in detail and particularly to Figure 1, indicates the usual pivoted phonograph tone arm, 11
tainer.
1927. Serial No. 206,035:
the reproduc'er or sound box, 13 the needle 'or stylus holder, 14 the combined stylus and sound amplifier of this-invention, and 15 a 'music record. Now referring to Figures 2 and the sound vessel or capsule comprises a thln walled cylindrical container 16 and having a tapered end 17. The tapered end of the container is provided with an axial 20 of cap 19 and the opening in the tapered end of container as shown to advantage in Figure 3. The tube22 should be inserted into and through the'taper'ed end of container previous to placing the cap 19 in position. In order toprovide differences of pressure upon the inside and outside of the container,
I exhaust all air from the container, as near as possible, and then hermetically seal the same by using solder or other means for connecting the tube 22 to the container and securing the cap 19 in position. The air may be exhausted from the, container by placing a small quantity of water therein and heating the same to form steam, and then applying the cap 19 and sealing said cap to the con The tube 22 should extend from the ends of the container or capsule as at 24 and25 respectively. The end 24 is of such diameter that it may be secured in a holder 13 of conventional construction. The end 25 of the tube 22 is slotted longitudinally as at 22 and a clamping ring 27 is slidable thereon.
As shown in Figures 1 to 3 inclusive the stylus comprises an elongated member 28 which is preferably made of bamboo or other suitable fibrous material. The point or pin 28 fits tightly within the tube 22 and the ring 7 27 serves to clamp the same against longitudinal movement. By employing a fiber stylus or needle the same eliminates any scratching of the music record and also permits sharpening the needle, from time to time, and in this way one needle may be used for a long period.
In Figure 3, I have illustrated how the stylus 28 may be adjusted. When adjustment of the stylus or needle is desired the sound vessel 14 is removed from the holder 13 and a small and still Wire 29 inserted in the tube 22 to a point for engaging the stylus 28. Further movement of the Wire 29 will project the stylus 28 to the extent desired.
The shorter the length of the stylus protruding from tube 24 the greater the volume of music reproduced from the record.
Referring to Figure the structure of the sound vessel or capsule andtube for holding the record-engaging element or stylus is the same as shown in Figures 2 and 3 and the reference characters employed for said parts in Figures 1 to 3 inclusive have been applied to Figure 5. It Will be noted in Figure 5 the needle or stylus 30 is made of tungsten or steel and preferably the record-engaging end is reduced as seen at 31. WVith this form of stylus I do not eliminate the scratching of a record. However, thesound amplifying employed in connection With the needle gives substantially the same desirable results as to tone and quality of the soundsreprodueed as When employing a fiber stylus. Also the volume if sound is greatly increased and Without distortion.
\Vhile I have shown and described the preferred form of my invention it isto be understood that I am aware of the fact that changes may be made in the general structure and arrangement of the parts by those skilled in the art Without departing from the spirit of my invention as indicated by the appended claims.
I claim:
1. In combination with a phonograph reproducer, a stylus, and a vibration amplifier interposed between the stylus and reproducer comprising a hermetically sealed vacuous container and means for connecting the same to the stylus and the reproducer.
2. A stylus attachment for a phonograph rcproducer, comprising a vacuous container, and means whereby a stylus may be secured in one end thereof, and means extending from the other end of the container for connecting the same to the reproducer.
3. A stylus attachment for a phonograph reproducer, comprising a vacuous capsule having a tube extending axially therethrough, one end of Which may be secured to .a reproducer, and a stylus fixed in the other end thereof.
4. A stylus attachment for a phonograph reprodueer, comprising a vacuous capsule, a
tube extending axially therethrough, one end of Which may be secured to a reproducer, and means for clamping a stylus in the other end of the tube.
