STYLUS-ADJUSTING DEVICE.

Specification of Letters Patent.

Patented July 22. 1913.

Application filed December 11, 1911. Serial No. 665,073.

T 0 all whom it may concern Be it known that I, GEORGE E. EMERSON,

a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Stylus- Adjusting .Devices, of which the following is a specification.

. This invention relates to'a. Stylus adjusting device for a sound reproducing apparatus, to obtain sounds of various amplitudes.

The invention comprises means for easily locating a stylus, so that it will protrude at different lengths from its socket member.

In the accompanying drawings Figure 1 represents a front elevation of a sound reproducer and a fragmentary view of a sound record and supporting disk, with an exemplification of the invention, Fig. 2 shows a partial section of Fig.1 on the line 2, 2, Fig. 3 is an enlarged fragmentary portion of Fig. 2, Fig. 4: shows a top view of the elements shown in Fig. 3, with a partial section thereof as in the line 4, 4, Fig. 5 is a rear view of Fig. 1, and Fig. 6 shows a left hand side view of Fig. 5.

The reproducer is shown with its casing 20 having the flange 21, which latter is somewhat extended at one end to form a supporting table 22. Vithin the said casing the vi brating disk 23 is supported in the usual way. Above the table 22 is located the socket member 26 with the triangular longitudinal opening 27 and outer end 28. It has extending from its sides a pair of lugs 31 in which are secured a pair of bearings The latter are supported on a pair of tapering pins 33, that extend from the table 22. A tightening screw 35 extends through the shell of the socket member to clamp the stylus 36. A screw bolt 37 has its threaded end in threaded engagement with the bottom of the socket member 26 and passes through an opening in the table 22. A curved spring 40 has an opening in its crown for said bolt and the ends thereof bear on the lower face of said table 22. A vibrating bar 42 at one end extends from the socket member 26, and has the other end fastened to the vibrating disk 23 of the I sound re roducer. A lever 43 is pivoted by means 0 the pin .44 to the bar 42, and has preferablyan elongated opening which engages a "pin 48 extending from the sliding plunger 50 having the abutting end 51. The sliding plunger 50 is located in the central opening 27 of the said socket; member 26, and is axially in line with theg tylus36 and can. bear against the end of the latter within the socket member 26. A plurality of openings 51,52, 53 are formed in the vibrating bar 42, to lock the lever 43 in different angular positions by means of pin 47.

The invention is usedby locking the lever 43 in any of its various positions by means of said pin t7, thereby locating the plunger 50 in different positions in the opening'27, so that the end 51 of the latter will be located at diiferent. distances from the outer end 28 of the socket member 26. The stylus 36 is then secured in the socket member 26 to abut against the sliding plunger'50 and the screw 35 is tightened in place. By this means the stylus 36 can bemade to protrude at different lengths from-the socket member 26, and with its varying lengths itre ceives vibrations of varying amplitudes, as it comes in contact with a sound record 55 supported on the table 56. The varying amplitudes are transmitted to the vibrating disk 23 to vary the sounds produced by the latter. With this invention one stylus takes the place of several when different sounds are to be obtained by the reproducer.

It is to be understood that the invention as described in this specification and-shown in the drawings can be modified from the particular exemplification represented without departing from the spirit'of the invention.

Having described my invent-ion what I desire to secure by Letters Patent and claim is:

1. In an apparatus of the character described the combination of a casin of a sound reproducer, a vibrating bar for the apparatus, a stylus for the apparatus ooa-cting with the vibrating bar, a plunger bearing against said stylus to cause it to protrude at various lengths from its support, and means to move said plunger in one'direction and in a direction opposite thereto.

2. In an apparatus of the character described the combination of a casing of a sound reproducer, a vibrating bar for the apparatus, a stylus eoacting with said bar, a plunger bearing against said stylus, means connected to the plunger to move it in one direction and in a direction opposite thereto and means to lock said plunger in dif- 'sound rep roducer, a vibrating disk ferent positions to protrude the stylus at various lengths from its support to cause the a paratus to produce-sound vibrations of di erent amplitudes. 3. In an apparatus of the character described the combination of a casing of a sound reproducer, a vibrating disk for the casing, a socket member for the casing, a vibrating bar connecting the socket member and the vibrating disk, a plunger within said socket member, means connected tothe plunger to move it in opposite directions, means to lock said plunger in different positions and a. stylus in the socket member abutting against said plunger. 4. In an apparatus of the character described the combination of a casing of a or the casing, a socket member for the casing, a plunger within the socket 1nember, a lever pivoted in the apparatuswith one end thereof pinned to said plunger, means to lock the lever in different positions and a stylus in said socket member abutting against said plunger.

5. In an apparatus of the character described the combination of a. casing of a sound reproducer, a vibrating disk for the casing, a socket member for the casing, a vibrating bar connecting thesocketmember and the vibrating disk, at table formed with the casing, a palr of pins extending from the table, a'pair of lu s on the socket member supported on sai pins, a flexible connection between said socket member and said table, a sliding plunger located within the socket member, means to move the plungel in one direction and i a direction 0pposite thereto and a stylfis in the socket member abutting against said plunger.

6. In an apparatus of the character described the combination of a casing of a reproducer, a socket member flexibly connected to the body of the reproducer', a vibrating disk within the body of the reproducer, a vibrating bar connecting said disk and socket member, a movable plunger within the socket member, a lever pivoted to the vibrating bar With one end pinned to said plunger, means to lock said lever in different angular positions on said vibrating bar, a stylus in the socket member abutting against said plunger and means to clamp said stylus in different operative positions. r. 7. In an apparatus of the character described the combination of a casin of a reproducer, a table extending from t 1e casing, a pair of tapering pins supported on said table, a socket member, lugs extending from said member bearing on said pins, a bolt extending from said socket member and passing through an openin in said table, a spring bearing between t e head of said bolt. and said table, a movable plunger within the socket member, a vibrating disk with in thecasing of said reproducer, a vibrating bar having a plurality of openings connecting said disk and the socket member, a lever with an opening pivoted to said bar and one end thereofpinned to said plunger, a pin to engage the opening in the lever with any of the openings in the vibrating bar, a stylus in the socket member abutting against said plunger in various positions thereof and a screw to clamp the stylus in place.

Signed at the borough of Manhattan in the county of New Yorkand' State of New York this 5th day of December A. D. 1911.
