SouxD-Box FOK Talking Machines. Leon F. Douglass, Philadelphia. Pa., assignor to Victor Talking Machine Co., Camden, N. J. Patent No. 831.546. The object of this invention is to produce a sound box for a talking machine in which the stylus bar is more delicately, perfectly and efficiently mounted than heretofore and also whereby the position and tension of the stylus bar may be quickly and easily adjusted. The further object of this invention is also to provide, in combination with the features above referred to, means for delicately mounting the diaphragm of the sound box, so that the same may be vibrated with the most delicate and minute vibrations of the stylus bar. Heretofore in sound boxes in which the stylus bar has been mounted upon a torsional device for giving a tension thereto or for holding said stylus bar in position the torsional device or spring has been attached rigidly to the casing of the sound box and to the stylus bar — that is to say. no means have been provided for the axial adjustment of the stylus bar so that its pressure or tension in relation to the diaphragm may be varied. Furthermore, heretofore when the diaphragm has been mounted between a pair of gaskets which contact with the marginal portions of the diaphragm said diaphragm is more or less confined by the surfaces of the gaskets and its free vibration to some extent hindered. This feature when taken in connection with the lack of adjustability of the torsional mounting for the stylus bar is a disadvantage which reduces the efliciency and quality of the reproduction by the sound box. Briefiy, this invention comprises the embodiment in a sound box of an improved torsional mounting and also a mounting which may be easily adjusted by means of suitable clamping or holding devices both in relation to the stylus bar or in relation to the bearings for the torsional device. It also comprises the combination. with the above features, of a diaphragm which is mounted so as to vibrate freely in response to the most minute and delicate vibrations of the stylus bar. Fig. 1 is a perspective view of the improved sound box; Fig. 2, a transverse sectional view thereof, taken substantially on a line passing longitudinally through the center of the stylus bar. Fig. 3 is a side elevation thereof, showing the device for torsionally mounting the stylus bar in cross section; and Fig. 4 is a view taken substantially upon the line 4 4, Fig. 3, showing a portion of the casing of the sound box. Magnetic Sound Record. Victor H. Emerson, Newark, N. J., assignor to American Phonograph Co.. Washington, D. C. Patent No. 831,779. This invention consists of the production of a magnetic sound record. In the drawings, Fig. 1 represents a side view of a talking machine. cording to this invention in the manner hereinal'.'.c', set forth. Fig. 1 is a side elevation of a phonogram with metallic end connections ready for application to an electro-deposition apparatus. Fig. 2 is a broken cross section of a phonogram and one of the metallic end pieces and connections; Fig. 3. a face view of one metallic end piece. Fig. 4 is a broken longitudinal section of metallic mold 01 shell; Fig. .5, a section of mold with all parts assemljled and duplicate phonogram or wax therein. Phonografii. William W. Rosenfield, New York. Patent No. 831,630. This invention relates to automatic return mechanisms for phonographs. In the drawings herewith Fig. 1 is a plan view of a phonograph ])rovided with automatic return mechanism embodying my invention. Fig. 2 is an elevation of illustrating the invention. Fig. 2 is a plan view of a sound record produced in accordance with the invention. Method of Duplicating Phonograms. Maurice .loyce, Washington, D. C, assignor by mesne assignments to New Jersey Patent Co., West Orange, N. J. Patent No. 831,668. This invention relates to the method of duplicating or multiplying phonogram cylinders, and the object is to reproduce facsimiles of phonogram cylinders in as large numbers as may be desirable. These cylinders are reproduced ac ihe return mechanism with the auxiliarv or return feed shaft broken away, so as to more clearly show other parts. Fig. 3 is a section taken on the line x x of Fig. 1 looking toward the left, and Fig. 4 is a section taken on the line y y of Fig. 1 looking toward the left, parts being omitted from Fig. 3 for clearness which are shown in Fig. 4. Phonograph Record Cleaner. Fi'ans E. Forsell, Providence, R. I., assignor to J. Newcomb Blackman, New York. Patent No. 832.249. This invention relates to an. attachment for cleaning the record on a phonograph, and has for its object to provide a lirush to l)e preferably suspended from the traveling arm that carries the reproducing point. It is found in practice that when a recording roll collects dust it .is apt to lodge in the grooves on the face of the roll, and if it is not thoroughly removed before the record is used this dust and grit comes in contact with the sharp point or edge of the reproducing needle and wears the same off and quickly destroys it. To obviate this difficulty a little brush is provided which may be made of hair, felt or other soft or suitable flexible material.
