' To aZZ whom it may concern:

Be it known that I, LOUIS P. VALIQUET, a citizen of the United States of America, and a resident of the borough of the Bronx, city, county, and State of New York, have invented certain new and useful Improvements in Tripod-Supports for Horns of Talking-Machines, of which the following is a specification. My invention relates in general to supports for horns used with talking-machines, and more specifically consists of an adjustable supporting apparatus for very long horns, which is primarily designed for use with the zonophone or similar talking-machines using a disk-shaped sound-record. It has been customary heretofore to support such long horns by various kinds of tripods or similar appa ratus; but when the ordinary form of tripod is used the vibrations set up in the various :0 parts seriously interfere with the correctness of the sound reproduction. Moreover, the tripod with the heavy horn restingthereon is in a condition of most unstable equilibrium unless given additional lateral support, and the maintenance of an accurate adjustment of the stylus to the record during the operation of reproduction is almost impossible unless the tripod is rigidly connected to the talking-machine case. My invention overcomes these difiiculties by means of a construction the preferred form of which is illustrated in the accompanying sheet of drawings, in which- Figure 1 is a side elevation of a talkingmachine, horn, and supporting apparatus. Fig. 2 is a detail, partlyin section, showing the telescoping joint used in my invention.

Fig. 3 is a detail of the universal joint for the.

swinging arm. Fig. 4 is a similar view, partly 0 in section, and showing different positions of the parts in dotted lines. Fig. 5 is an enlarged detail of the end ofthe rigid arm which is fastened to the case of the talking-machine. Throughout the several figures of drawings like reference-figures indicate like parts.

As shown in the drawings, the talking-machine 1 has a rotating-disk sound-record 2, on which rests the sound reproducer 3 in the usual manner. To this reproduccr or soundbox 3 is attached the horn 4:, which is of such length that it cannot be supported from the casing of the talking-machine in the usual manner. The sound-box 3 is carried by the swinging arm 5, having the extensible telescoping portion 5 fastened thereto in an adjustable manner by the set-screw 6. The other end of the swinging arm 5 is preferably adj ustably held in a casting 7 by the set-screw 8. This casting is hinged to the pivot-pin 9 by the horizontal pin 10, and the pivot-pin 9 being swiveled on the upper end of the rod 9 by resting in the sleeve 23, fastened on the upper end of rod 9 a universal-joint mounting for the swingingarm 5 is thus provided.

The vertical rod 9 is adjustable upward and downward accordingto the height of the table 11 or othersupport on which the talkingmachine 1 rest-s by reason of its telescoping into the standard '12, in which it is held by the set-screw 13. The standard 12 is supported by any suitable base, such as the tripod 12. The fork 22, which screws into or rests in the recess 21 in the upper portion of the casting 7, supports the horn 4.

To insure proper adjustment of the parts and prevent vibration thereof, I provide the rigid arm 14, which is the main feature of novelty in the structure. One end of this arm is hinged to the casting 15, which is clamped to the vertical rod 9 by the setscrew lti. The other end, which consists of thetelescoping rod 17, held in adjustment by the set-screw, 18, has the eye 19 (see Fig. 5)

formed in it, by which it may be rigidly fastened to the talking-machine 1 by the setscrew20, which is also employed to fasten the ordinary horn-supporting bracket in place when a shorthorn is used.

The operation of my invention is as follows: The standard 12 being set up, the extension 9 is adjustedso as to bring the fork 22 at the proper height for supporting the horn 4. The rigid arm l tis then fastened to the casing 1 by the set-screw 20 passing through the eye 19 and extended in a substantially horizontal position, the outer end being supported by clamping the casting 15 to the rod 9 by the set-screw 16. The length of the rigid arm is so adjusted by means of its telescoping section 17 that the hinge 8 comesjust below the center of gravity of the horn, soundbox, and swinging arm taken as a whole when the casting 7 is in a horizontal position, as shown in full lines in Fig. 4. If tipped to either side, as shown in dotted lines, the center of gravity will fall to that side and maintain the stylus in engagement with the soundrecord or hold it supported above the same. The intermeshing parts of the hinge are so shaped as to engage and prevent the soundbox from falling far enough to strike the table 11 if the stylus runs off the record. The length of the swinging arm 5 5 is correspondingly adjusted by means of the sliding joint described, and the machine is ready for operation. The rigid arm 14 clamps the parts together and prevents internal vibrations. It also secures the continued proper adjustment of pivot 9 with reference to the record. The apparatus can be similarly adjusted for any length of horn and any height of table. When taken apart, the arms 5 and 14 fold down beside the standard 12, the tripod-legs 12 fold together, the various parts telescope into one another, and the whole apparatus is in compact form for transportation.

The advantages of my invention comprise its rigidity, simplicity, adj ustahility, compactness, and the ease with which it may be attached to any zonophone by simply removing the ordinary bracket and fastening the arm 14 17 in place by the same set-screw 20.

Of course various changes could be made in the details of construction shown without departing from the spirit of my invention so long as the general arrangement of parts shown in the drawings or the principle of op eration explained in the specification be preserved. 7

Having therefore described my invention,

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

ing-machines, the combination of the vertically-extending standard or support and base therefor, the horn-supporting fork, the swinging arm pivoted on said support and adapted to carry the sound-box and small end of the horn on the inner end, the rigid arm extending from the upper portion of the support and means for attaching the other end of said rigid arm to a talking-machine, said standard being vertically extensible.

3. In ahorn-supporting apparatus for talking-machines, the combination of the vertically-extendin g standard or support and base therefor, the horn-supportin g fork, the swinging arm pivoted on said support and adapted to carry the sound-box and small end of the horn on the inner end, the rigid arm extendingfrom the upper portion of the support and means for attaching the other end of said rigid arm to a talkingmachine case, said standard, swinging arm and rigid arm being all adjustable lengthwise.

4:. In a horn-supporting apparatus for talking-machines, the combination of the vertically-extending standard or support and base therefor, the horn-supportin g fork, the swinging arm pivoted on said support and adapted to carry the sound-box and small end of the horn on the inner end, the rigid arm extending from the upper portion of the support and means for attaching the other end of said rigid arm to a talking machine case, said rigid arm having a hinged connection to the vertical standard, whereby the same may be folded together when the arm is detached from the talking-machine case.

5. In a horn-supportin g apparatus for talking-machines, the combination of the verti cally-extending standard or support and base therefor, the horn-supporting fork, the swinging arm pivoted on said support and adapted to carry the sound-box and small end of the horn on the inner end, the rigid arm extending from the upper portion of the support and means for attaching the other end of said rigid arm to a talking machine case, said standard, swinging arm and rigid arm being all adjustable lengthwise and detachably connected together.
