it being evident to one skilled in the art that other suitable modified forms of such con nections may be employed in lieuof those illustrated. f
To vary the sound emitted from the horn, I provide a valve or plug G2 which ts into the end of the tubular part G Where it is secured to the head of the bracket. This valve G2 is formed like a tube, closed at one end and having a lateral lopening G3 adapted to come into alinement with a similar lateral opening G in the tubular part G within the head of the bracket and below the horn. B y rotating the valve or plug G2 the orice G may be moi'e or less throttled to vary the freedom of passage of the air vibrations. In this way the music or sounds may be subdued when desired.
The tubular connection shown, comprising the parts G, H, form a telescopic joint, but other forms of joints or adjustable tubular connections may be employed if so desired.
Having now described my invention, what I claim as'new and desire to secure by Letters Patent, is zl. In a sound reproducing machine, the combination of a rectilinearly movable sound box or reproducer, meansfor guiding and supporting the said. sound box, a bracket having a tubular end, a horn having its weight supported by .the bracket but adjustable circuinferentially thereon, mechanical devices for positively feeding the sound box relatively to lthe horn, and an adjustable tubular connection between the sound box and the tubular end of the bracket and formed of a plurality of telescoping mem' bers arranged parallel to the line of travel of the sound box, part of said members being secured to the bracket independentlyA of the horn and part of said members being secured to the sound box.
2. In a sound reproducing machine, the combination of a rectilinearly movable sound box or reproducer, means for guiding and supporting the said sound box, a bracket having a tubular end, a horn having its weight supported by the bracket but adjustable circumferentially thereon, and an adjustable tubular connection between the sound box and the tubular end of the bracket consisting of telescoping parts of rigid material, one of which is connected with and supported by the bracket by a goose neck independently of the horn and the other with the sound box and extending therefrom parallel to the lineof travel of the sound box. f'
3. In a sound reproducing machine, the combination of a rectilinearly movable sound box or reproducer, means for guiding and supporting :the `said sound box, mechanical devices for positively feeding the sound box relatively 'to the horn, a bracket v having a tubular end, a horn having its weight support-ed by the bracket but adjustable circnniferentially thereon, and an adjustable tubularI connection between the sound box and the horn consisting of a xed tubular part supported by the bracket f and having along tubular part parallel to the travel of the sound box and a sliding straight tubular part telescoping with the fixed tubular partand connected to and moving with `the sound box through the 7 medium of a fiexible joint.
4. In a sound reproducing machine, the combination of a rectilinearly movable sound box or reproducer, means for guiding and supporting the said sound box, a bracket having a tubular/end, a horn having its weight supported by the bracket but adjustable circumferentially thereon, an adjustable tubular connection between the sound box and bracket, 'and a valve for 8 throttling the sound vibrations arranged in the tubular end of thebracket so as to be iixedly supported during the travel of the sound box.
5. In a sound reproducing machine, the 9 combination of a rectilinearly movable sound box, means to rotate a sound record, means for guiding and supporting said sound box, a iixed support independent of the sound box and a'lso of the horn and 9;
having a tubular part, a horn having its weight wholly supported-by the fixed support and having its smaller end detachably connected to one end of the tubular part of the said support, and a tubular connection between the sound box and the other end of the tubular part of the support consisting of telescopicosections of rigid material one of which sections is connected with the tubular part of the fixed support and independent of the horn and held in fixed position relatively to the means for rotating the sound record, and the other section connected with the sound box and sliding on the iii-st mentioned ixedly supported secl tion. y
6. In a sound reproducing machine, the combination of a fixed horn supporting bracket, a horn wholly supported by and adjustable thereon, pelled sound box, and an adjustable tubular connection between the bracket and the sound box consisting of two telescoping parts one of which is stationary and supported nected with the sound box and having a long tubular part extending parallel to the direction of travel of the sound box and united to the sound vbox bya exible joint a mechanically prol by the bracket and the other conl tocoinpensate for irregularities in the alinef' ment of the parts in operation.` i
4. In a sound reproducing machine. combination 'of a rectilinearly met soiuid box or repre-rincer, means for gui and supporting thesaid sound box, a fixed 1 supporthaving a tubular bearing, a horn having its Weight' supported by the bearing but adjustabe ciroumferentiaily thereon,
an adjustable tubular' connection between the' Sound box and the bearing consisting of teleecoping parts one of which is connected with and supported by the been ing independently of the horn ,and having n 'tubular portion i'ixedly arranged @eretitel to the line-o tiove of the sound bei: and A Athe other of said sound box and having a sliding connection With'the tubular tioned part.-
