TROMBONE.

SPECIFICATION forming part of Letters Patent No. 530,781, dated December ll, 1 894.

ppli ion filed May 18,1894. Serial No. 511,638- (No model.)

To all whom it may concern:

Be it known that I, FRANK A. LELAND, a citizen of the United States, residing at orcester, in the county of Vorcester and State of Massachusetts, have invented a new and useful Improvement in Trombones, of which the following is a specification.

The object of my invention is to provide an improved wind instrument, and the especial object of my invention is to provide a trombone with a pitching valve, a supplemental pitching pass and asupplemental tuning slide for said pass which shall be located in a convenient and accessible position, where they will be protected from accidental derangement or injury.

To these ends, my invention consists of the parts and combinations of parts as hereinafter described and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective view of a trombone constructed according to myinvention. Fig. 2 is an enlarged sectional view of the pitching valve and supplemental pass and tuning slide which I preferably employ. Fig. 3 is a similar view showing the parts in a diiferent relative position, and Fig. 1 is a detail sectional view taken on the line 4-4 of Fig. 2.

Referring to the drawings and in detail, A designates the mouth piece, which is connected to and leads into the induction pipe B, the induction pipe 13 being connected to and supported by a return pipe 0, by means of a. brace or tie-rod Ct.

D represents the slide which fits telescopically over a portion of the induction pipe B and the return pipe 0, and is provided with a brace or tie d.

Secured to and connected with the return pipe 0, by means of the braces or ties c, e and e is the ordinary flaring portion or bell E. The bell E and the return pipe 0 are connected by an adjustable elbow F, fitting within the return pipe 0 and a section of E forming the ordinary pitching slide.

The parts thus far described may be of any ordinary or approved construction, and it has been found in practice that an instrument thus constructed cannot readily be changed from one pitch to another, because it the tuning slide F be pulled out too far, the comparative tapers of the pipes or passages will be changed, causing inaccuracy and variations in the sounds produced. To overcome this difficulty, and to provide a construction which can be quickly changed from one key to another, I provide a pitching valve 10, which is located in the return pipe 0 between the braces e and e and which controls a supplemental pitching pass.

The forms of valve and supplemental pitching pass and tuning slide, which I preferably employ, are most clearly illustrated in Figs. 2, 3 and 4. Referring to these figures, it will be seen that the pitch valve is formed by a tapering valve plug 17 fitting into a suitable valve casing, and having parallel passages 18 and 19. The tapering valve plug 17 is provided with a valve stem 25, to which an operating handle 21 is secured by means of the screw 22. At its opposite end, the tapering plug 17 is provided with a small screw 20, which fits into a slot formed in the valve casing, and limits the motion of the valve in either direction.

Fitting over the ends of the valve casing, and holding the parts in place, I provide suitable threaded covers or caps 23 and 24, as shown. \Vhen the parts are in the position shown in Fig. 2, a clear passage is left through the return pipe 0, and the pitching valve does not affect the instrument. hen, however, the parts are turned to the position shown in Fig. 8, the passage 19 through the valve plug, connects with a pipe 12,and the passage 18 connects with a parallel pipe 13. The pipes 12 and 13 are connected by an adjustable elbow 1 1-, which forms a supplemental tuning slide, and is provided with a knob or handle 16 for moving it to the desired position.

As shown in the drawings, the pipes 12 and 13 are connected by a small brace 15 in order to stiffen and strengthen the structure. By thus providing a trombone or other wind instrument with a pitching valve and supplemental pitching pass and tuning slide, it will be seen that I have greatly increased the range of utility of the instrument; that the key of the instrument can be quickly changed, and that the instrument may be accurately tuned without destroying the comparative taper of the passages. It will also be seen that by locating my pitching valve and supplemental pitching pass and tuning slide between the braces e and c I have provided a construction in which the parts are near the mouth piece and are easily accessible, and the valve and supplemental pitching pass and tuning slide will be so situated that they will be protected from accidental derangement or damage.

Of course my pitching valve and supplemental pitching pass and tuning slide could be applied in the same manner and equally as well to a trombone or other wind instrument which is controlled by finger keys and pistons. I do not wish, therefore, to be limited to the exact construction which I have shown and described.

I am aware that it is not new to provide a wind instrument with a pitching valve, and I do not claim such a device broadly as my invention, but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a trombone or similar wind instrument, the combination of a return pipe and a flaring portion or bell, a supplemental pitching pass arranged between said return pipe and bell, and a pitching valve for controlling the pitching pass, substantially as described.

2. In a trombone or similar wind instrument, the combination of a return pipe and a flaring portion or bell, a supplemental pitching pass and tuning slide arranged between said return pipe and bell, and a pitching valve for controlling the pitching pass, substantially as described.

3. In a trombone or similar wind instrument, the combination of a return pipe, and a flaring portion or bell, brace-rods or ties for connecting these parts, a supplemental pitching pass located between said brace-rods, whereby the same will be protected from accidental derangement or injury, and a pitching valve for controlling the pitching pass, substantially as described.

4:. In a trombone or other similar Wind instrument, the combination of induction and return pipes, a valve casing located in said return pipe, a tapering valve plug located in said valve easing, a pitching pass controlled by said valve, and a supplemental tuning slide located in said pitching pass, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRANK A. LELAND.
