ATTACHMENT FOR CORNETS AND OTHER BRASS INSTRUMENTS.

Specification of Letters Patent. PatentedApr; 22, 1919- Application filed December 30, 1918. Serial No. 268,896.

To all whom it may concern:

- Be it known that} I, CARL'J. MAGIN, a citiadapted to be used for changing the tone of a cornet or .other similarmusical instrumentof the kind generally referred to as brass instruments, without materially diminishing the'volume =of"the 'sound produced by the instrument.

Themain'object of-my invention is to provide a device for making a cornet or other musical instrument sound substantially like a saxophone.

Another object is to provide a saxophone attachment for musical instruments of the character commonly known as brass instruments; that is compact, inexpensive to -manufacture and easy to apply to or remove from the instrument with which it is used.

Figure 1 of the drawings is a side elevational view of a cornet equipped with a device constructed in accordance with my invention.

Fig. 2 is an enlarged longitudinal sectional view of said device; and

Figs. 3 and 4: are cross-sectional views, taken on the lines 3-3 and H, respectively, of Fig. 2.

My improved device consists of a member that is adapted to be arranged in front of the bell of the instrument on which the device is used and constructed in such a manner that it will convert the natural tone of the'instrument into a relatively deep tone, and means for sustaining said member in operative position on the instrument.

In the form of my invention herein shown the device consists of a relatively long hollow, cone-shaped member A closed at one end and arranged with its opposite end presented toward the bell 1 of the instrument,

and a su' porting means B for said member that projects into the bell of the instrument, as shown in Fig. 2. I prefer to support the member A on the instrument by means or a substantially frusto-conical-shaped member B of slightly smaller diameter than the member A, arranged oppositely to said'member A and having its large end connected to the large end of the member A in such a manner that the sound waves which enter the member 13 can pass into the member A. In the form of my invention herein shown the large end of the member B is partially telescoped within the large-end of the member A and permanently connected to same, but this is not essential to the successful operation of my ,device. The supporting :member B is open at its small end or inner end and is provided with means for connecting said member to the bell 1 of the instrument and holding it spaced awaylfromthe' bell sufiiciently to permit someof-thesou-ndproduced by the instrument to escape through a passageway lying betweenthe belland' the supporting member B. In the form of my invention herein shown the supporting member B is provided at its inner end with a plurality of lugs or ribs 2 that bear snugly against the contracted portion of the bell of the instrument, and thus hold the member B securely in position and spaced far enough away from the bell to provide a passageway through which some of the sound can escape, the lugs or ribs preferably, but not necessarily, being formed of cork or other material that has some resiliency, as such an attaching means holds the supporting member securely in position and permits the device to be easily applied to or removed from the instrument.

I The supporting member B is so constructcd that it will not materially interfere with the sound waves passing into and out of the member A, and while said supporting mem ber can be constructed in various ways to accomplish this result, I prefer to provide the member B with one or more slots or openings 3 that extend longitudinally of said member from a point in proximity to the inner end of same to a point in proximity to the outer end of said member which is joined to the member A.

A device of the construction above described, when arranged in operative position on a cornet, trombone, baritone horn, French horn, alto born, or any of the other musical instruments of the kind commonly known as brass instruments, will make the instrument sound substantially like a saxophone, due to the fact that the hollow cone-shaped member A is arranged in such a position with relation to the bell of the instrument that it will convert the natural tone of the instrument into a relatively-deep tone. The. device is small and compact enough to enable it to be carried conveniently in a coat pocket; it can be applied to. or removed fromithe instrument easily and it is of such simple design and construction th at it can be manufactured and sold at a low cost.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A device for changing the tone of musical instruments of the character-referred to, comprising a relatively long, hollow, coneshaped member, closed at its apex, an oppositely-disposed, frusto-conical-shaped member, open at both ends and having its large end connected to the large end of said coneshapedmember so as to cause the sound waves which enter said frusto-conicalshaped member to pass into said cone-shaped member, said frusto-conical-shaped member being'adapted to be inserted in the bell of the instrument, and openings in the sides of said frusto-conical-shaped member; for the purpose described.

A device for changing the tone of musical instruments of the character referred to, consisting of a hollow member of substantially cone shape whose large end is open, a frusto-conical-shaped member arranged with its large end pro ecting intothe open end of said cone-shaped member and connected to same, lugs on the outer end of saidfrustoconical-shaped member that are adapted to be forced into'the contracted portion of the bell of the instrument, and elongated slots in the sides of said frusto-conical-shaped member located between said lugs'and the point where said member is attached to the coneshaped member. i

3. A device for changing the tone of musical instruments of the character referred to consisting of a relatively long, hollow, coneshaped member open at its base end, an oppositely disposed frusto conical --shaped member arranged with its base end projecting into the base end of said cone-shaped member and secured to same, and elongated slots in the sides of said 'frusto-conicalshaped member, for the purpose described.

CARL J. MAGIN.
