THOMAS A. EDISON, OF LLEWELLYN PARK, ORANGE, NEW JERSEY, ASSIGNOR TO THOMAS/A. EDISON, INCORPORATED, OF WEST ORANGE, NEW JERSEY, A CORPO- RATION on NEW JERSEY.
PHONOGRAPH-REPRODUCER.
. Specification of Letters Patent.
Patented Mar. 5, 1912.
Application filed June 11, 1908. Serial No. 437,843.
T all whom it may concern:
Be it known that'I, THOMAS A. EDISON,
a citizen of the United States, and avresident of Llewellyn Park, Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Phonograph-Reproducers, of
. which the following is a description.
' ing to the original sound 'waves.
The object of my invention is to secure a louder and more perfect reproduction than can be obtained from the ordinary form oit' reprodueer, or to secure a reproduction of equal loudness with less wear upon the record. lVith this end in view I employ a pair of reproducer styluses, one of which is arranged slightly in advance of the other with respect to the record groove, so that both styluses track the same groove together, and although the one stylus is slightly in advance it does not interfere with the other because of the elongated character of the record groove, In other words, each sound or note which is recorded on the record consists of so many-elevations and depressions that the two styluses are operated practically simultaneously with respect to the record of each individual sound, however minute.
Reference is hereby made to theaccompanying drawing, of which- Figure 1 is a side elevation, partly in section, of a phonograph reproducer constructed in accordance with my invention, and Fig. 2 is a bottom plan view of the stylus lever, styluses and a portion of the floating weight.
The reproducer shown comprises a sound box body 1 of ordinary form, within which the diaphragm 2 is clamped by the ring 3 in the usual manner. The floating weight 4 is pivoted at 5 to the block 6 carried vby the bodyl, and the stylus lever 7 1s pivoted on the screw 8 carried by the lugs 9 which depend from the weight 4. One end ofthe lever 7 is connected by the link 10 to the center of the diaphragm 2, and the other end of the lever is provided with a pair of sockets which receive the reproducer styluses 11 and 12, the former being slightly in advance of the latter with respect to the groove of the sound record at. These styluses may be of any form adapted to track the said groove, but I have shown and prefer to use styluses of the type known as button-balls, as fully set forth in my patent reissue No. 11,857, dated September 25, 1900.
Having now described my invention, what I claim is:
1. In a phonograph reproducer, the combination with a vibratory member, of a pair of reproducing styluses adapted to coact with a sound record, means for supporting said styluses in position to track the same groove of a sound record, said styluses being positioned sufliciently closely together to be operated in the reproduction of the record substantially simultaneously by the same note recorded on the record, but not to in:
terfere with each other, and means for transferring the vibrations of said styluses to said vibratory member, substantially as described.
2. In a phonograph reproducer, the combination with a vibratory member, of a stylus lever connected-to said member and a pair of reproducing styluses carried by said lever, adapted to coact with a sound record and track the same groove, said styluses being supported with their-operative surfaces located in substantially the same plane parallel to the grooves of said sound record when the reproducer and record are in operative position and in substantially the same plane tangent to said record, substantially as described.
3. In a phonograph reproducer, the combination with a vibratory member, of a floating weight, a stylus lever carried by said weight and connected to said member and a pair of styluses carried by said lever, adapted to coact with. a sound record, said styluses This specification -signed and WitII BSSGd this 8th day of June 1908.

being supported with their operative surfaces located in substantially the same plane parallsl to the grooves of said sound record when the reproducer and record are in operative position and in substantially the same plznis tangent to said record, substantially as ilescribed,
