ATTACHMENT FOR TALKING-MACHINES.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed April 22, 1914. Serial No. 833,627.

To all whom it may concern:

Be it known that I, CHARLES S. MCNALLY, a citizen of the .United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Attachment for Talking-Machines, of which the following is a specification.

My invention consists of an attachment for supporting a sound-box of the type employed in talking machines operating with records having the so-called hill-and-valley sound-grooves, such as the Edison records, upon the tone-arms of talking machines normally operating with records having a laterally waving sound-groove, such as the Vict'orand Columbia records, so as to adapt such latter type machines to operate with an Edison sound-box upon Edison records.

It further consists of means for adjusting the sound-box upon such machines in its relation to th records.

It further consists of other novel fea tures of construction, all as will be hereinafter fully set forth.

The annexed drawing and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In'said annexed drawings-Figure 1 rep resents a plan view of a Victor talking machine, illustrating an Edison sound-box and record applied to the same. Fig. 2 represents a side-elevation of as much of such machine as will illustrate the application of my device. Fig. 3 represents an end view of said parts. Fig. 1 represents a detail view of the attachment. Fig. 5 represents a detail view of a device for'connecting the elbow-tube supporting the soundbox with the goose-neck.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the reference numeral 1 indicates the casing of a talkingmachine having a rotatable turntable, 2, for a disk-record, 3, and a laterally swinging tone-arm, 4. Said parts are substantially alike in machines of the Victor .or Columbia type, and operate essentially in the same manner in allmachines of these types.

In Figs. 1, 2 and 3 the is a Victor machine, and

talking machine the usual goosehas its upwardly projecting neck, 7,

neck, 5, is movably secured to the end of the tone-arm. A soundbox, 3, of the type employed in the Edison talking machine,

se- 8, in the downwardly cured by a set-screw,

10, the horibent'arm, 9, of an elbow-tube,

zontal arm of which is secured in the outer end of the goose-neck by a collar 3 1, secured upon the tube by a set-screw, 11,*and having a tongue, 35, engaging the L-shaped= slot, 36, in the goose-neck by which the Victor sound-box is secured. The support for the sound-box consists of a metal rod or wire, 12, one end of which is'bent to form a curved cradle, 13, in which the elbow-tube rests. The rod 'is bent at rightangles and doubled to form a finger, 14, and the portion of the rod which forms a continuation of the rod-portion having the cradle, is bent and doubled in.a plane at a right angle to that of the finger to form an car, 15, in

which a fulcrum-screw, 16, ;is threaded,

whereupon the rod is bent parallel with the finger and curved upward to form a hook 17.

\Vhen it is desired to reproduce from an Edison or hill-and-valley record, such record is placed upon the turntable, and the Edison sound-box has the elbowtube secured to it and such tube secured to the end of the goose-neck from which the Victor sound-box has been removed. The cradle of the support is placed beneath the elbovwtube and the doubled finger and the hook are placed astride the inner end of the goose-neck, with the hook engaging beneath the tone-arm. fulcrumed with the end of the fulcrum screw resting upon the joint, 18, of the gooseneck and tone-arm, and the weight of the sound-box, elbow-tube and goose-neck is carried by the cradle, as the other end of the lever formed by the support engages be neath the tone-arm, which in this type of machine is vertically immovable. The sound-box is thus carried by the support and the tone-arm, and may be raised and lowered away from and toward the record by the fulcrum-screw to have its jewel-point,

19, or whatever form of needle or stylus de I contact with the The support will thus be down vibrations of the jewel-point and he amplified by the Victor machine amplifying devicesf By the use of an Edison sound-box and the support preventing vertical movement of the tone-arm, Edison records or similar records of the hill-and-valleytype may be reproduced on talking-machines of the Victor or Columbia. types, so that the amplifying and rotating mechanisms of such machines can be used in reproducing sounds from any make of record.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made asregards the mechanism thus disclosed, provided the principles of construction set forth, respectively, in the following claims are employed.

I claim as new and desire to secure by Letters Patent, is

1. An attachment for talking machines, comprising a curved cradle adapted to engage a goose-neck and arms adapted to straddle the inner end of the goose-neck, one of said arms forming a hook to engage around a tone-arm, and also formed with Having thus described my invention, what an ear between said arms, and a fulcrumscrew through said ear and adapted to bear upon the outer end of the tone-arm.

2. In combination with a tone-arm, a gooseneck, and a sound-box having its dianeck, and means for unyieldingly raising and lowering the gooseneck supporting por-' tion of such support.

3. In combination with a tone-arm, a gooseneck, and a sound-box having its. diaphragm and stylus facing downward, of a tubular elbow adapted to be fitted into the end of the gooseneck and to have said sound-box secured in its other end, a support adapted to be stationarily supported upon the tone-arm and to engage and support the elbow and for unyieldingly raising and lowering the elbow and gooseneck supporting portion of such support.
