The talking machine world (Jan-Dec 1912)

52 THE TALKING MACHINE WORLD. sound will be increased, the tone clarified and the enunciation made mor distinct and natural. Another object of the invention is to provide a clarifier for this character which will be simple and inexpensive in construction and efficient in operaton, and which may be quickly and easily engaged with and removed from its operative position. In the accompanying drawings, Fig. 1 is a side view of a portion of a graphophone having the invention applied thereto; Fig. 2 is an enlarged side view partly in section of the reproducer, and the tone arm with the invention arranged therein ; Fig. 3 is a crosssectional view on the line 3—3 of Fig. 2; Fig. 4 is a detail perspective view of the clarifier. Stop Mechanism for Phonographs. Oscar W. Hartung, Detroit, Mich. Patent No. 1,016,563. This invention relates to means for stopping the record-supporting table of talking machines after they have made a predetermined number of revolutions, and its object is to provide a stop mechanism which can be set for any desired number of revolutions within its range without the necessity of altering the adjustment of any of its parts, but by merely positioning an indicator for the number of revolutions desired. This invention consists, in combination with a spring actuated brake adapted to engage the supporting table of a sound reproducing instrument and a lever to hold same in inoperative position, of a graduated dial, a pointer adapted to be swung over the dial to indicate the number of revolutions, a notched disc against which the lever presses and which holds the lever outward until the predetermined number of revolutions have been made by the table, a toothed wheel to turn thr notched disc and pointer, and an operating device to actuate the toothed wheel, which device is operated by the mechanism which revolves the table that is to be stopped. In the accompanying drawing Fig. 1 is a plan of the stop mechanism, a portion of the dial being broken away for clearness. Fig. 2 is an elevation of the same with the case broken away. Talking Machine. John C. English, Camden, N. J., assignor to the Victor Talking Machine Co., same place. Patent No. 1,016,255. The main objects of this invention are to provide a talking machine having an inclosed cabinet provided with a plurality of openings, and an amplifier in the cabinet and adjustable to register with any one of said openings ; to provide a talking machine inclosed in a cabinet having a sound outlet in one side thereof and which is adapted for convenient operation in a corner of a room or in a similar position ; to provide a compact, inclosed talking machine having a comparatively large storage space for records and comparatively large and efficient sound amplifying means; to provide a talking machine having a sound amplifier provided with an outlet in a casing, and in which means are provided to deflect the vibrat i o n s transmitted from the side of the amplifier upwardly or in a direction different from that in which the vibrations are delivered from the outlet of the amplifier. In the accompanying drawings Fig. 1 is a front elevation of a talking machine, constructed in accordance with this invention ; Fig. 2 a rear elevation partly in section of the same; Fig. 3 a side elevation of the same partly broken away to show the amplifier ; Figs. 4 and 5 a rear elevation and a fragmentary side elevation partly in section of the upper portion of the same, showing the rear door thereof open ; Fig. 6 a fragmentary horizontal section on. the line 6 — 6 of Fig. 2, and Fig. 7 a side elevation partly in section of the amplifier. Record for Talking Machines. Eldridge R. Johnson, Merion, Pa., assignor to the Victor Talking Machine Co., Camden, N. J. Patent No. 1,016,271. Heretofore in the manufacture of flat disc records for talking machines it has been the practice to stamp out the record discs from a suitable material by means of a die containing a matrix upon the surface of which has been engraved or otherwise placed the record grooves, which grooves, in connection with the sound box are adapted to reproduce the sounds impressed upon the original record. The record discs formed. by so impressing the matrices have usually been of some durable material which softens under the influence of heat, but which is hard and firm under normal conditions of temperature. The material usually employed for making these records has been in the form of flat sheets -which have been of uniform thickness throughout the entire extent of the disc with the possible exception of the central portion, where the label has been impressed or countersunk into the material during the pressing or forming of the record. This material, in many instances, has been the substance called "duranoid," which consists of shellac and certain other coloring pigments and strengthening ingredients. Other similar materials which have been used are hard rubber and celluloid. It will be realized that these compositions are expensive when used in large quantities, especially in view of the fact that talking machine records now employed in this art have been steadily increasing in size. The object, therefore, of this invention is to produce a record which may have all the advantages of a flat disc record of uniform thickness, but which will at the same time be much lighter and therefore less expensive in original cost and also will be easier to handle and less expensive in transportation either by mail, freight or express. A further object of the invention is the production of a record which will have strengthening means applied in such a manner as to give a stiff and firm backing for the reproducing surface without the necessity of employing the larger amount of material required in a disc record made entirely of duranoid or other similar substance. Briefly, this invention comprises a disc record having upon its under side a metallic plate or backing made in different forms so as to retain the record material firmly in position and at the, same time, to protect the record material from injury to which it would otherwise be liable owing to its reduced thickness. The metallic backing may also 'extend across the central portion of the record not occupied by the record grooves and may form a centering means for the record when placed ^y upon the turntable. The central portion of the record may also be occupied by an independent disc of metal or other material which forms the centering means and which is fixed in position during the stamping or forming process. Fig. 1 is a reverse plan view of a talking machine record having the strengthening plate applied thereto. Fig. 2 is a transverse sectional view of the form of record shown in Fig. 1 and Fig. 3 is a transverse sectional view of a modification showing the centering disc placed in position independently of the metallic backing. OPENS TALKING MACHINE STORE. M. Bame, Former Victor Co. Traveler, to Handle That Line at Retail in Atlanta, Ga. (Special to The Talking Machine World.) Atlanta, Ga., March 4, 1912. I. M. Bame, who has been well known to Atlanta for a number of years as a traveling representative for the Victor Talking Machine Co., has severed his connection with this company and will go into business for himself here. He has organized the I. M. Bame Co., which will occupy commodious quarters at 72 North Broad street, where the most elaborate talking machine parlors in the South will be opened about February 22. Mr. Bame will handle the Victor line exclusively. You would object to another placing a limit upon your business ability.
