APPLUATION FILED DEO.. 8. 1-906:

a3 which is produced by the bottom of the case a and the horizontal partition a4 and to hold the said portion h2 rigidly in place, upper and lower supporting plates h3 may be provided. The vertically disposed portion h of the magaphone is located entirely without the case as shown, although it is practically protected from injury in shipping by means'of the ledge a2, and this portion oi the megaphone is provided With a sound regulator r which may be set by a handle 1" so as to regulate the opening for the passage oi the sound waves from the diaphragm and the tapering arm to the lower part of the horn. v f

In the lower, enlarged, conical portion -h2 of the horn are arranged thin longitudinal wires w which are supported at their ends by oval Wires w which are attached to the side-Walls of the horn and which serve for vibrating with the sound-waves as they are conducted from the' vertical portion of the horn to the horizontal portion, said wi'rcs exertingv a softening inf fluence on the sounds and delivering the same in a clear and distinct manner at the-outgoing end of the horn.

The advantages of my improved phonograph are that the horn is not arranged as a separate detachable por# tion of the same7 but is arranged in permanent -connection with the lower part of the casing, so that the same can be packed and -shipped with the casing, the phonograph being immediately on unpacking the shipping box ready for use, all that is necessary being to arrange the sound-record on the rotary table or disk, regulate the stylus for the same, and adjust the suspension-pivot of the upper hollow tapering arm ot the horn. The lower enlarged part of the horn remains always stationary in' the box, while the upper part 'with the sound-box follows the motion of the depressions in the sound-record as is capable of swinging on the suspension-pivot in lateral direction, while the Vertical Amotion of the sound-boxl and its tapering arm necessary for removing and replacing the sound-record is permitted by thc pivotal connection of'the elbow with the holder. The sound-box in the lower part of the casing for the enlarged part ot' the horn and the longitudinal wires in the same improve the softness and clearness ofthe sounds which are emanating from thesame andyrender the sounds more pleasing and agreeable.

Havinv thus described the invention what is o y claimed as new is:

1` In a talking,r machine. the combination with :i case. a record'table journnled upon said case, a sound box and supporting; arm therefor. of :i ring.;l mounted upon vsaid case, a bracket extending upwardly und forwardly from said ring to a point over the' saine. n stirrup consisting of :in inverted U-shaped bauand an unnulus connected to the lower ends of said bar, the said nnnulus being fitted to turn within the said ring, a pivot lpin mounted in the upper end. of suid bracket and extending through the same into contact with the said bar, an elbow received within the stirrup and pivoted to the har thereof to rock in :1 vertical piane, one end of said elbow receiving the suid supporting arm for the sound box, a megaphone having, a stationary portion disposed horizontally within the case and etxending therethrough, said niegaphone also embodying a vertically disposed portion extending from one end of the stationary portion up to the elbow.

2. In a talking,- machine, the combination of a case, a

record tuble mounted to revolve on said case, a sound-- box and supporting' arm therefor, the top of the case being provided with a rearwardly projecting ledge having an opening formed therein. of :1 stationary inegaphone disposed within said case and provided' with an elbow extending outside ot' the ease und up into the ledge, a universal joint connected between the supporting arm and said elbow,` and n sound regulator' mounted in the. said
