ERNSTA. GOUIUBIER, OF GHICAGO, ILLINOIS.

CORNET.

To all whom it may concern:

Be it known that I, ERNST A. Cou'ronmn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Cornets, of which the following is a specification.

My invention relates to cornets and has for its object the provision of an improved valved wind instrument which shall have means for producing more perfect tones than have heretofore been possible from cornets.

With the above and other objects in view, this invention consists substantially in the combination, arrangement, and construction of parts, all as hereinafter described, shown which form a part of this specification and show the preferred embodiment of my invention, and

more specifically set forth in the subjoined claims. 7

In the accompanying in the accompanying drawings,

drawings which form a part of this specification and which illustrate the preferred embodiment of my invention, Figure 1 is' an elevation of one side of the comet with some parts broken away and one valve shown in interior elevation. Fig. 2 is an elevation of the opposite side of the cornet. Fig. 3 is a horizontal section of a valve'on the line 3-3 of Fig. 1. Fig. 4: is a section through a part of th e pipe and a removable portion thereof. Fig. 5 is a detached elevation of a removable section of the comet. Fig. 6 is an elevation of a section of tubing interchangeablewith the section shown in Fig. 5 and somewhat longer. Fig. 7 is an elevation of a section of tubing interchangeable with the section shown in Fig. 5 and somewhat shorter.

To produce the most desirable tone from a cornet it is essential that the vibration roduced at the mouth piece be conveyed to the bell of the instrument through a constantly enlarging pipe, and it is a detriment to the cornet now in use that they have, intermediate the mouth piece and the bell, a number of cylindrical portions of the pipe. In order to produce the most desirable sounds from a cornet I provide that the pipe through which the vibrations produced at the mouth piece pass shall be constantly expanding fromthe mouth piece to the bell,

this expansion to Specification of Letters latent.

Application filed September 3,1912. Serial No. 718,182.

strument is used in the well known open position or with any combination of the valves.

In the drawings reference numeral 10 indicates the mouth piece of the instrument; and 11 is the bell thereof; 12, 13 and 14: are the valves; 12 i is the valve pipe of the valve 12, 13 is the valve pipe of the valve 13, and 14 is the valve pipe of the valve 14. It is at times necessary to alter the number of vibrations produced by the cornet in order to adapt it to the exact pitch of other instruments. This is done in the ordinary cornets by lengthening the pipe through which the vibrations pass and this lengthening is accomplished by pullin out, as far as necessary, U-shaped slides of the pipe of the instrument. The ordinary corn'et has such slides, both on the valve pipes and on a section of the pipe through which all vibrations must pass whether the valves are in use or not. The pulling out of these slides leaves cylindrical pockets in the pipe which are detrimental to the quality of tone produced from the instrument. For tuning the instrument I provide that an approximately U-shaped section 15 of the pipe thereof intermediate the mouth piece and the valve casing be removable and when it is desired to lengthen the pipe for varying the pitch I provide a longer section 15, shown in Fig. 6, of a shape similar to 15 and interchangeable therewith or, should it be desired to shorten the pipe, I provide a shorter sec tion 15" shown in Fig. 7 similarly shaped and interchangeable with section 15. The long section is of such a length as to lower the pitch of the cornet one-eighth of a tone or less, and the shorter section is so constructed as to raise the pitch one-eighth of a tone or less; thus the cornet is given a range of pitch of one-quarter of atone or less. By this interchange (if members I avoid the interposition in the pipe of any cylindrical portion adjacent the member 15. This appears more clearly in Fig. -lin which the gradual expansion of the pipe somc-- what exaggerated. 1G is a portion of the mouth pipe from the mouth piece of the instrument: 17 is that portion of the mouth pipe nearest the bell from member 15. The cud lb of the .mcmbcr 15 is adapted to be sheathed in the orming parts as itwcomcs to the member 15 i e of the ma mal; time the end 17 of the member 15 isadapted to be "sheathed ine) the slightly enlarged; inner portion 17 of the pipe 17. When these, two endsare 'respectivelysheathed,the continuity of' the pipeof thefinstrument remains unbroken,

I and while it would be possible to partially withdraw the member from its full en ga'gement with the portionsflG and l'r' of the pipe and thereby vary the pitch of the instrument, it is a'fact that such actipn would impair the tone produced by interposing inthe' pipe 2 cylindrical pockets. It

i is to avoid the forming of any such pockets sov that I provide for tuning by means of a plurality of members similarly shaped -to member 15,01? varying lengths, and interchangeable therewith.

In'Fig.-3 one of the apertures 18 is illustrated in section and the enlargement somewhat exag.-.-

In the accompanying drawings and in the foregoing specification are set forth the preferred embodiment of my invention but it is obvious that one skilled in the artmay make modifications thereofwithout departing from the principle of the invent-ion.
