.ALEXANDERl N. PIEEin'rN,l -oE NEWARK; NEW JERSEY, AssIGNoE I'rjo NEW JERSEY PATENT COMPANY', OF WEST ORANGE, NEW JERSEY) A CORPO- EATION oF NEW JERSEY.

.MAN, a .citizen of the United States, residing at Newark, in the countyof Essex' and State of New Jersey, have invented'certain new an'd useful Improvements in Phonic Apparatus, of which the following is fa description.

My invention relates to phonic apparatus ofthe type wherein a rotating friction-wheel is used in combination lwith a` friction-shoe pressed against the same, power Vbeing a plied for rotating the friction-wheel, and t e pressure between the friction-shoe and fricap' aratus. zo

instrumentality of a tion-wheel bein varied bywsuitable means-l representative o sound-vibrations, thus producing variations in the amount oi` friction,

which by suitable mechanical connections may ,operate a diaphragm ori-.other phonic l ily invention relates more y ar'ticularly to devices for reproducing soun sthrough the honographic record,

the phonographic sty us being connected with said frictlon-shoe andA operatingto varythe amount of friction.

Heretofore, as far as I am aware, the friction-wheel-hasalways been driven from a stationary motor, and the said friction-wheel has either been mounted so asf to have no. progresslve motion or 1n case'jit has been mounted on a traveling carrier the driving mechanism has been so arranged that the' friction-Wheel may receive its power from.

the said stationary motor during its move- I Tlent with the carriage. These devices-tare objectionable, however, because they are'not readily applicable to an ordinary phonograph and require specialvforms of instruments, which are expensive to construct and which in some cases cannot be used with an ordinary phonographicspea-ker. My invention has for its general objec the provision'of a mechanism of the character referred to and more particularly its application to a phonograph oi ordinary construction, so that the mechanism may be interchangeable with an ordinary phonographic reproducer without the, addition of any parts whatsoever to the ordinary phonograph. Thisobject has been carried out by the mounting of a complete frictional reproducing. apl aratus upon a vbase which is adapted to t within the kordinary car- Specication of LettersPatent. v.replication nea 0mm-14.1995, serai Nu. 282.710.'

The phonograph shown in Fig. l is'of the Ausual Well-known construction* and comprlses a main shaft ail: driven by means of anysuitable stationary motor, (not shown,) such as a spring or electricf motor, situated usually below the same n and transmitting power thereto by meanso'f? a Vbelt passing over 'the drive-pulley b.
