' Application filed April 27, 1904- Seriel No. 205,041-

Be it known that we, FRITZ-LOOHMANN and WILLIAM LOCHMANN, sub'ects of the King Saxony, resrdlng at Zeu enroda TI, Reuss,

Germany, have invented new and useful Inn ,provernents 1n Talkin Machines with Rotatable Horns, of which the following is a specification: I

talking-machines or graphophones in use the horn or sound-trumpet is permanently div reoted to one side, and consequently the machine is generally best heard from this side.-

if, however, the entire box of the talking-rnachine is mounted on a rotatable base, the winding mechanism partakes oi the rotation and is located now at one side and then at another. These objections'according to this invention are to be overcome by arranging the holder of the horn rotatably about the center axis of the talking-machine, so that by simply turning the holder or carrier the horn can be set to any direction, while the machine itself retains its position undisturbed;

This invention is illustrated inthe annexed drawings, in which- Figure 1 is a sectional view of a talking machine with rotatable or adjustable horn. Fi 2 is a plan view of Fig. 1.

The central axis 6 passes through the housing a of the machineand, as known, is intended for supporting and rotating the speakin'gplate or record 0. The horn dis a so supported, as known, on a carrier e.

According to this invention the carrier e for the horn d is rotatable about center axis b, so that-it can be set to any side without reuiring the housing a of the machine to be 'sturbed or its position on its base to be changed. The horn can thus be brou ht to various (positions, as indicated by. otted lines, an allowed to throw sound in anydirection. Such change of direction can also be made While the machine is in operation.

The manner in which the horn-carrier e is arranged to rotate about the center axis b is not material so far as this invention is conearned, since any'well-lmown arrangement I as desire centric to center axle b to the housings; but the holder" e might as Well be in form or a turntable journaled on the housing or a ring, which in case of a ring-shaped housing might rotate thereabout or about aring-shapedplate applied to the housing, or an arrangement of any other suitable-kind could be applied for rotatably supporting the holder 6 about axle b. The rotation of thehorn could also be accomplished mechanically by the inion device when, for exam le, to the ex e g a pinion- Wheel i is applie ,which engages a gear-Wheel h, secured to box or sleeve f or to the hollow axle of rotation of the horn-carrier e. This arrangement can be made releasable, for example, by arra-n ing the pinion 'i shiftably on axle 9, so that te connection of such pinion with the ear-Wheel can be made or broken.

dl Any other desired coupling can be utilized to adapt the device for releasably conveying the movement of rotation from axle g to bushing f.

What we claim as our invention, and desire to secure b r Letters Patent, is-

l. A tailing-machine comprising a rotatable horn-carrier mounted centrally with respect to the machine.

2. A talking-machine com rising a horn-- carrier rotatable about the riving-axle of the machine.

3. A talkin -rnachine comprising a housing, a horn, a older and a driving-axle, said holder being rotatable about the drivingaxle of the machine to enable the horn to be directed toward various points without disturbing the housing.

4. A talkingmacbine comprising a housing or cabinet, a horn, a holder or carrier for the horn, and 'a driving-axle releasably gearedto-the holder for rotating or adjusting the direction of the same without disturbing the housing.

5. The combination with a disk graphohone, of a horn-support adjustable circumrentially in respect to the disk 6. The combination with a disk graphoset our hands in the presence of two sub phone, of a horn-support rotatable around scribing Witnesses.
