To all whom may concern); a U

.Be it known that we, HENRY'B'. BABsoN and ANDRE HAUG, citizens of the United" States of America, and residents of the borougli ofqManhattan, city, county, and State I of New York, have invented certainnew and useful Improvements in Talking-Machines, of which the following is a specification.

Our invention, relates generally to talking machines and more particularly tosupport ing means'for mounting the; reproducer in operative relation to the. horn. In certain types of machines of this class nowin genparts, the care and accuracy required in fit-v ccivcd general approval, objection ismade to the particular forms ofmechanism heretofore employed, owing to the large number of ting andassembling the parts to insure proper cooperation and the general complication involved in the construction which renders it expensive, difficult to adjust and altogether unsatisfactory from the point of view of both the manufacturer and'user.

. The present invention is designed to obviate the objectionable features above pointed out in'the production of ar'eproducer sup-' porting arm and mounting therefor en1ploy-,

- ing a minimum number of parts of a form suitable for-being manufactured at a comparatively low cost, readily assembled or disconnected and so arranged as to co-act c'lliciently in permitting free movement of the reproducer and its ready adjustment in or out ofoperative relation to the sound record.

The accompanying drawings will serve to illustrate a device suitable for carrying our invention into effect. We wish it understood, however, that We do not limit ourselves to the particular mechanism or' arrangement of parts shown, as various other devices may be employed operating in substantially the same manner to produce practically the same result.

In the drawings: Figure 1 is a vie win side similar viewtaken on t elevation of a support for a sound reproducer, constructed I in accordance with our invention, the same being shown applied to a j well-known type of talkinigmachine; Fig.- 2

Interposedbetween and operatively connecting the reproducer and. horn there is a sound con'veyer in theform of a tubular taper arm 10, whichserves to'supportthe reproducer' and at the same time forms a continuation of the sound chamber thereof. At the end adjoining the horn, the taper arm terminates in' ing a-portion l2 the sleeve-like ofi-set'of the brac'liet5', and thus mountedit is centered relatively to the smaller end of the horn; The sleeve'fserv'es,

elbowof which unites therewith to form ineffect a ball and socket joint. The arm is supported by a spring. 13, acting through a V 1 pin 14, the rounded end of which enters a groove. 15, formed in'theu'nder side of the 80 an elbow 11, which is shown as ajcastinglha'va shaped to fit loosely within 35 merely ,as a guide for the taperarm theelbow as best shown in Fig. 4, The spring and J pin are seated in an opening or socket 1 6 of the bracket and form" a yielding support upon which the arm is free to move both vertically and horizontally. The yielding action or tension of the spring may be varied by means; of a screw 17, secured if desired by a lock nut 17. Rounded'lugs 18, 18, formed at diametrically opposite points upon the elbow and bearing against, the lower end of the guide sleeve, j pin, which tends to force-the elbow into the sleeve, and in addition to mainta ning these parts in definite relation, ,serve as the ful-L crum for the arminits vertical movement.

In order to protect the reproducer when not in use, provision is made for. locking the arm 10, at an angle such as is indicatedjby 1 dotted lines in Fig.1, in which position the limit the action of the spring stylus clears the record. This is effected by forming a depression 19 at one end of the groove 15, in thQRQlbOW 11, into which depression thebin 1 4 is forced by thespring notches 20,

' when swung around against further move .object being to prevent persons with the machine from placing the reproducer with the stylus in such posi-, ,"tion as to oppose movement 0ft If desired, a stop lug 2l may be motion.- When moving vertical thearm rocks on the lugs 18 an d the'spring pin 14, riding in the groove' 15,-yield's, as requ1red,to
