CHARLES G. CONN, OI ELKHART', INDIANA.

CQRNET.

Application filed October 8, 1914.

lb all whom it may concern:

Be it known that 1, CHARLES G. Conn, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in-Cornets, of which the following is a specification.

The object of my invention is to avoid the short turns found in the wind passage of cornets heretofore used and in so doing,

produce an instrument which plays freer,

better and more satisfactorily in every way and at the same time gives a greater volume Another object of my invention is to place the tuning slide between the valves and rear end of the bell tube and in close proximity to the thumb of the operator s hand when in playing position, so that the player may tunethe instrument as he plays by turning the thumb screw which is connected to thetuning slide.

In the drawing Figure 1 is a side elevation of a eornet embodying my invention;

Fig. 2 is a similar view of a side of a cor net opposite to that shown in Fig. l.

The reference numeral 1 designates a mouth pipe and 2 the valves of a cernet of any approved construction. 3 designates the bell tube, or bell, the bore of which is of a gradual taper from end to end.

4ris a quiclr-ehange-to-llt slide in the I mouth pipe.

The principal tuning slide, as shown in. the drawings, is positioned between the valves and. the inner end of the bell 8, in an upright or perpendicular position. llhat to say, the principal tuning slide is upright or perpendicular to the main longitudinal lines of the cornet when the cornet is held in playing position.

The member 5 of the principal tuning slide is shown in the drawings as leading from the first valve casing, but it is, of

course, obviou. that it may lead from either of the valve casings as found most desirable. This member is deflected downwar lyand thence upwardly to a vertical or per pendicular position. 6 is another upright member of the main tuning slide which is of greater diameter than the member 5 and Specification of Letters Patent.

of a diameter equal to the inner end of the bell pipe. 7 is the slidingmember of the main tuning slide, one leg of which is of diameter equal to the diameter of the member 5 while the other end is of a greater diameter and equal to the diameter of the member 6, from which it will be seen that the wind passage, commencing atthe top of the member 5 is of increasing diameter through the slide 7, member 6 and the bell pipe 5 i ich results in the instrument playing freer, better and more'satisiactery and which enables me to get a greater/volume of tone out of the instrument.

I have shown in the drawing a bracket 8 secured between the members 5 and 6 of the tuning slide in which bracket is revolubly mounted a thumb nut provided with interior screw threads while 1' have secured a stem 10 to the slide member '2', one end of ing freer and giving better satisfaction and I a greater volume of tone. In the old style of cornet, it was necessary to remove the cornet from the players' lips in order to tune it, it often requiring several trials before the desired tone could be attained, whereas in my invention the player can tune his instrument while he is playing, by simply moving his thumb over the knurled thumb screw 9, thereby not losing single note of the composition. I

I claim l. A cornet having a tuning slide in the form of an open-ended, vertically arranged loop, positioned between the first valve casing and the mouth piece, said loop comprising part of the tube connecting said casing and the bell tube; a thumb nut held against axial movement and a coacting screw held against rotation. positioned within the aforesaid loop for. adjustingsaid tuning slide.
