154 THE TALKING MACHINE WORLD June 15, 1919 LATEST PATENTS RELATING TO TALKING MACHINES AND RECORDS— (Continued from page 153) tical sectional view of the machine shown in Fig. 1. Fig. 3 is a fragmentarj' plan view of the feed mechanism shown in Figs. 1 and 2, but on a larger scale. Fig. 4 is a left-hand side elevation of a portion of the said feed mechanism, as shown in Fig. 3: said mechanisrri being in idle position, disconnected from the motor which drives it. Fig. 5 is a fragmentary, sectional, front elevation of a portion of the feed mechanism shown in Figs. 1 to 4 inclusive. Fig. 6 is a fragmentary plan view, similar to Fig. 3, but showing the said mechanism in operative position, in connection with the motor which drives it. Fig. 7 is a fragmenta'rj% vertical, sectional view of the feed mechanism terminal stop device, taken on the line 7 in Fig. 3. Fig. 8 is a plan view of a modified form of initial stop device. Fig. 9 is a fragmentary elevation of the initial stop device shown in Fig. 8. Fig. 10 is a plan view' of a modified form of an initial stop device. Fig. 11 is a front elevation, and Fig. 12 is a side elevation, of a modified form of initial stop device, of the same general character as the terminal stop device shown in Fig. 3 and which may be substituted for the initial stop device shown in that figure. Fig. 13 is a fragmentary perspective view of the bracket attached to the tone arm, aflfording a support for the fulcrum of the feed mechanism lever, and a support for the sound box when the latter is upturned into idle position. Fig. 14 is a side elevation, similar to Fig. 4, but showing a more compact arrangement of the cam and gear shifting mechanism, designed for the smaller type No. IX Victor machine, but adapted foi use in the larger. No. XVI, machine indicated in Figs. 1 and 2. Reproducing Device for Graphuphones. — Henry Rolland Adams, Wayside, Tex. Patent No. 1.301,631. This invention relates to reproducing devices for graphophones, and one object is to provide certain novel means for mounting the diaphragm in order that the vibrations shall be transmitted from each side thereof to a plurality of ducts having connection with a main duct or tone arm through which the sound passes to the horn or the like. A further object is to provide a casing comprising a plurality of semispherical members with means for mounting a diaphragm across the chamber formed by said members, and means for connecting the opposite sides of the semispherical members with a common air duct, or tone arm. A still further object is to provide certain novel means for mounting the needle and comprising a conical member carried within a tapered seat and separated from said seat by a sleeve of fiber, this conical member having connection with the arm connected with the diapliragm of the reproducing device. Figure 1 is a longitudinal central section il lustrative of the best practical embodiment of the invention that has been devised; the said section being on the line 3 — 3 of Fig. 1. Fig. 2 is a view, partly in plan and partlj' in section, •.nil the upper casing section removed. Fig. 3 is a section taken in the plane indicated by the line 3 — 3 of Fig. 2. Sound Box Mounting. — William T. Lakin, Long, Md. Patent No. 1,301,458. This invention relates to improvements in phonographic tone arms. An object being to provide a tone arm including as one of the essential features a conduit, so mounted upon the end of the tone arm as to be capable of being swung completely back out of the way, making the turntable accessible for the placing and removing of the records. Another object of the invention is to provide a tone arm. including a reproducer neck, adjustably mounted upon the end of the sound conduit, making the reproducer adaptable to both vertically cut and laterally cut records. Another object of the invention resides in the manner of pivotally supporting the tone arm and of affording also a continuous unbroken tone passage. Figure 1 is a plan view of the tone arm. Fig. 2 is a detail cross section of the sound conduit mounting on the tone arm. Fig. 3 is a detail section of a portion of the mounting. Fig. 4 is a detail section of the coupling connecting the reproducer to the reproducer neck. Figs. 5 and 6 are face views of the opposing portions of the sound conduit mounting. Fig. 7 is a side elevation of the parts shown in Fig. 1, portions being shown in sections. Figs. 8 and 9 are detail views of a portion of the reproducer neck, and Figs. 10 and 12 inclusive are detail views of several modifications of bearing pins. Reproducer for Talking Machines. — Henry T. Crapo, Boston, Mass. Patent No. 1,302,140. The immediate object of this invention is to provide simple, but effective, means for use with the needle bar of such reproducers whereby a specially sensitive action is given to the needle as the latter follows the grooves of the record, the said invention briefly described consisting of a novel arrangement of a plurality of permanently magnetized points which act with J6 — je 3_ a cushioning or balancing effect upon the needle bar, in opposition to the vibrating diaphragm. For the purpose of explaining the said invention clearly the annexed drawings have been provided, in which the Figure 1 is a plan view of a reproducer embodying the present improvement, looking down upon the vibrator dia phragm needle bar, and Fig. 2 is a transverse sectional, view of the same taken on the line 2 — 2 of said Fig. 1. Fig. 4 is a relatively enlarged view of the magnetized spider 15 and of the needle bar located thereunder, and Fig. 3 is a transverse sectional view taken on the line 3 — 3 of said Fig. 4. Phonograph. — Clemma R. Raney, Chicago, 111. Patent No. 1,302,217. This invention has among its objects to provide an improved phonograph. It also aims to provide improved means whereby a series of records may be reproduced in a predetermined succession continuously and automatically. A further object is to provide improved means whereby a series of records arranged in predetermined order may be successively supplied to the record rotating mechanism of the machine and improved means whereby they may be discharged therefrom after they have been reproduced. A still further object of the invention is to provide improved means for controlling the sound arm and needle of the reproducing mechanism in such a manner as automatically to place the same in starting position upon a record, and improved mechanism whereby the sound arm may be automatically returned to its initial position after the completion of the record. More specifically, the invention has among its objects to provide improved and cooperating mechanism whereby the several results mentioned above may be obtained in the desired sequence, and to produce a machine adapted to reproduce a predetermined series of records automatically and continuously, which will function with certainty and accuracy during a protracted period of service without the necessitj" for repairs, which is capable of use even in the hands of an unskilled operator without danger of breakage, and which may at the same time be manufactured at small expense. In these drawings Figure 1 is a partial plan view of this machine equipped with improvement, a portion of the record table being broken away to facilitate illustration. Fig. 2 is a side elevation of the mechanism shown in Fig. 1, a plurality of records being shown in the machine and portions of the frame-work of the latter being broken away to facilitate illustration. Fig. 3 is a side elevation of a portion of the mechanism, the record carrying support being shown in elevated position ready to receive the records. Fig. 4 is a detail sectional view of the record support showing the same in normal position and ready to discharge one of a plurality of records thereon. Fig. 5 is a detail side elevation of a portion of the record support. Fig. 6 is a detail transverse sectional view of the record table and its counter-balancing and rotating mechanism. Fig. 7 is a partial plan view of one form of record showing the different series of grooves and the axial rings thereon. Fig. 8 is a detail view showing the sound arm in inoperative position with respect to a record. LESLEY'S PATCHING VARNISH dries in 10 seconds, flows without showing the lap.
