RFZPRODUCER-SUPPORT FOR GRAlVIOPHONESQ.

SPECIFICATION forming part of Letters Patent No. 742,666, dated October 2 7, 190s;

Application filed August 8, 1900. Serial No. 26,279.

(No model.)

To all whom itmay 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 Pennsylvania, have invented certain new and useful Improvements in Reproducer- Supports for Gramophones, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to certain improvements in gramophones, and more particularly to the mechanism for supporting the reproducer and its horn.

The object of the said inventionis to provide improved means for holding the soundbox to its supporting-arm and mechanism for clamping the horn to the sound-box.

The invention consists in the construction and arrangement substantially as herein set forth, and fully pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, and in which similar letters of reference are used to indicate similar parts, Figure 1 is a side elevation of a gramophone having my improvements applied thereto. Fig. 2 is a plan view illustrating the reproducing mechanism in position on its supporting-arm, a portion of the supporting-arm and horn being omitted. Fig. 3 is a detail view showing the reproducer-arm and clamp in elevation and the tubular section of the sound-box and horn in section.

In the said drawings, A designates the casing containing the motor mechanism, andB the revolving turn-table which supports the record C.

Extending from one side of the casing A is a bracket-arm D, carrying on its outer end a sleeve cl, in which is pivotally mounted a bifurcated arm 01, which has the reproducerarm E pivoted thereto.

On the inner end of the reproducer-arm E, I secure a flat plate g, having a split ring g, formed integral therewith and extending out beyond the end of the arm E, the inner diameter of the said ring g being of a size sufficient' to snugly fit the tubular section h of the reproducer or sound-box H, so that when the section a is forced into the ring ring will firmly bind against this portion of the reproducer and hold it in position. on the top of the arm E, I secure a spring-clamp I, secured to the said arm E by means of the screws '6. The free end of the arm E is bent in circular form and has secured to its end a. solid piece of metal 1', in which is a screw threaded aperture adapted to receive the lower end of an adj usting-screw J. The upper portion of the screw erture in the upper portion of the clamp I, as clearly illustrated in Fig. 3 of the drawings. Thus when the sound-box is placed in the support g the tubular section 71 of said soundbox also extends through the circular portion of 'the spring-clamp I, and when the end of the horn Z is placed over this tubular section it it also passes in the circular portion of the spring-clamp I, and by regulating the adj usting-screw J the band I is caused to bind the horn-section and the sound-box section together, and thus form atight connection and a firm support for these parts. The elbow Z on the inner end of the horn is generally made of leather and is of a size sufficient to snugly embrace the tubular section of the sound'box; but from constant usage this leather tube stretches and does not engage with sufiicient degree of firmness to hold it in position, and consequently very often has to be tied or wrapped with wire, which is inconvenient and unsightly. My spring-clamp above described obviates any such difficulties and firmly holds the end of the horn to the soundboX and also helps to support the sound-box in its operative position. By unscrewing the screw J the spring-band I is expanded, and the horn and sound-box can be immediately removed.

Having thus described my invention, what I claim, and desire to secure by Letters Pat g the said ent, is-

1. In a talking-machine, 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 opening to hold the tubular portion of the reproducer and being split to form spring clamp- J passes through an aping-sections, a spring-band also secured to form spring clamping-sections,aspring-band said arm and means for clamping said springalso secured to said arm and means for clampband, substantially as described. ing said spring-band about said flexible con- 2.
