NEW JERSEY.

A CORPORATION OF SPECIFICATION formingpart of Reissued Letters Patent No; 12,213 dated April 26, 1904.

Original No. 742,666, dated October 27, 1903. Application for reissue filed December 26, 1903. Serial No. 186,758.

To all whom, it rmty concern:

Be it known that I, ELDRIDGE R. JOHNSON, a citizen of the United States, and a resident of the city of Philadelphia, State of Pennsyl- Vania, have invented certain new and useful Improvements in ReproducerSupports for (irramophones, of which the following is a full, clear, and exact disclosure. v

This invention relates to certain-improvements in gramophones ortalk'ingmachines,

and more particularly to mechanism for sup- 5 removed independently of the other.

. For afull, clear, and exact description of one v form'of my invention reference may-be had to the following specification'and to the accom- 'pailnylilng drawings, forming a part thereof, in

Figure 1 is a side elevation of a gramophone or talking-machine having my improvement applied thereto; Fig. 2, a plan view illustrating the reproducing mechanism or sound-box iii-position on the supporting-arm, and Fig. 3 a detail view showing the reproducer-arm in elevation and the tubular section of the soundbox and horn in section.

Referring to the drawings, A indicates the 4 casingcontainingthemotormechanism, above which isthe revolving turn-table B, whichsupports the record C.

Extending from one side of the casinglA v a bracket-arm D, carrying on its outer end a i sleeve (1, in which is pivotally mounted a bifurcated arm I), which has the reproducerarm E pivoted thereto. v

' On the inner end of the reproducer arm E,

-I secure aflat plate g, having a ring G, which may be split, as indicated at g Said ring is 5 preferably formed integral with said plate 9 and extends out beyond the end of thearm E, the inner diameter of said ring G being sufiicient to cause said ring to snugly fit the tubular section it on the reproducer or sound-box H, so that when the sectionaz isplaced in the ring-g the said ring will firmly hold the reproducer in position.' Omthelop of the arm E, I secure a spring-clamp'I, which is secured to the said arm E by means of the screws 2'.

The free end of thespring clamp or bandiI is bent in circular form and carries adjacent its enda solid piece of metal I in the nature of a nut, in which is a screw-threaded aperture adapted to receivieothe lower end of an adjust- 5 ing-screw J. upper portionof the screw J passes through an aperturein the upper portionof the clamp I, as clearly illustrated in' Fig. 3ofthe drawings. Thus when the soundbox is placed in the ring g the tubular sec 7 tion it of said sound-box extends through the circular portion of the spring-clamp I, and when the end of the horn Z is placed over the tubular section H it also passes within the circular portion of the spring-clamp 1'. By regulating the adjusting-screw J the band I is contracted to bind the hornand the soundbox together, and thus form a tight connection and a firm support for'those parts. The elbow Z on the inner end of the horn is generally made of leather and is of. a size sutficient to snugly embrace a tubular section of,

wrapped .with wire in many instances, which is inconvenient and unsightly. My springclarnp above describedobviates any such difficulties and firmly holds the end'of the horn 9 i with the reproducer-arm, of a support adapted to receive'and hold the soundebox in position,

to the sound-box. It also helps to support the sound-box in its operative position. unscrewing the screw J a spring-band I is allowed to expand, and the horn and sound-box may be immediately separated and either or both removed. It will also be noticed that the sound-box may be removed from the supporting-arm without detaching the elbow Z therefrom by simply loosening the screw J and allowing the soundrbox to be withdrawn. The elbow and horn may also be removed independently ot' the sound-box, for when the said elbow is not in position Within theclamp I the sound-box is supported by the ring 9'. These features of construction particularly adapt the parts ofmy device to be easily assembled and separated, which is of great advantage where it is desired to carry the machine from place to place. I

Having thus described one form of my invention, what I claim, and desire to protect by Letters Patent of the United States, is-' 1. In' a talking-machine, a reproducer-arm provided with independent means for supporting the communicating ends of the sound-box and amplifying-horn, said means being independent of the sound-passage establishing communication between said sound-box and horn.

2. In a talk1ng-mach1ne,-the' combination andmeans for receiving the end of the amplifying-horn and for holding the same in po.

sition and in operative relation to the soundbox, said support and means beingindependent of the sound-passage establishing communication between said sound-box and horn.

3. In a talking-machine,.a reproducer-arm provided with means independent of each other for supporting the communicating ends of a sound-boXand amplifying-horn, one of said means operativ'ely engaging both the sound- 1 box and horn when assembled, said means be- 1 ing the small end of the amplifying horn in position about a portion of said sound-box.

5. In a talking-machine, a reproducer-arrh,

a sound-box, a horn, said sound-box entering a portion of said horn, means for holding said I sound-box in position, and means for holding said horn inposition, and for holding said sound-box and horn in engagement with each other, said means being independent of the sound-passage establishingcommunication between said sound-box and horn.

6. In a talking-machine, the combination the sound-box.

and means forclamping said spring-band.

with the reproducer-arm, of an annular support secured to the free end of said arm, and adapted to receive and hold the sound-box in position, and means also attached to the free end of said arm for holding the amplifying horn in position and for clamping the same to 7. In atalking-machine, a-repr'oducer-arm, a sound-box, a horn having a compressible portion carried thereby, a sound-box engaging said portion, means for holding said sound-box in position, and means for compressing the compressible portion of said horn into contact with said sound-box.

8. In' a talking-machine, the combination with the reproduccrarm, of a plate secured thereon having an opening therein to receive the tubular portion of the sound-box and a clamp also carried by said arm adapted to hold thev small end of the amplifying-horn in position and t0.clamp the same to the tubular portion of the sound-box.

9. In a talking-machine, the combination with the reproducer-arm, of a plate secured to the free end thereof and comprising a ring adapted to receive and hold the tubular portion of a sound-box in position, and an adjustable clamp also carried by said arm for holding the small end of the amplifying-horn in position and for clampingthe same to the tubular portion of the sound-box.

10. In a talking-machine, the combination with the reproducer-arm, of a ring secured thereto for receiving the tubular portion of a sound-box, a band also secured to .said arm andmeans for contracting said band. l 11. In a talking-machine, the combination With the reproducer-arm and reproducer, of a ring secured thereto and adapted to receive the tubular portion of a'sound-box, a band also attachedto said arm and a thumb-screw' for contracting said band.

12. In a talkingmachine, the combination with the reproducer-arm and reproducer, of a plate secured to the free end of the arm having its'end projecting beyond the same, the

said end being provided with a circular open- 1 ing to hold the tubular portion of the reproand means for contracting said spring-band.
