JAY WARREN MOYER, OF PHILADELPHIA, PENNSYLVANIA.

GRAPHOPHONE-POINT.

SPECIFICATION forming part of Letters Patent No. 658,571, dated September 25, 1900.

Application filed J'iine 221 1900.

T0 at whom it may concern.-

Be it known that I, J AY WARREN MOYER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Styluses for Graphophones, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a stylus for a graphophone, &c., composed of a hollow body and a tip thereon, whereby the sound is increased in volume and made crisp, distinct, and melodious, while harsh and disagreeable vibrations are obviated.

Figure 1 represents a perspective view of a graphophonic reproducer having a stylus embodying my invention applied thereto. Fig. 2 represents a diametric section of the stylus, showing also the reproducer and the record in dotted lines.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a reproducer of a graphophone of usual construction.

B designates a stylus, which is constructed of a hollow glass body 0, of conical or tapering form, and a glass tip or bulb D, which projects from the apex or point of the body and is set at an angle to said body, so as to be presented to the record at an acute angle,

and thus to offer less resistance to the rotation Serial No. 21,220. (No model.)

of the record, the conical or tapering form of the body causing the chamber therein to increase in capacity from the apex to the reproducer. The base of the stylus is secured to the diaphragm E of the reproducer A over an opening F therein, it being evident that when the graphophone is in operation the sound will be sharply taken up from the record by the bulb D and increased, avoiding harshness and the like, the sound being readily transmitted Without material resistance to the reproducer through the opening in the diaphragm thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A stylus consisting of a hollow tapering glass body, and a glass tip on the apex thereof. 2. A stylus consisting of a hollow tapering body and a tip on the apex thereof, said tip projecting from said apex at an angle thereto. 3. A stylus consisting of a hollow tapering body, and a tip on the apex thereof in combination with a reproducer and a diaphragm.

on the latter, said body being secured to said diaphragm and said diaghragm having an opening which is in communication with the chamber of said body.

JAY WARREN MOYER.
