SLIDE-TROMBONE.

SPECIFICATION forming part of Letters Patent No. 468,116, dated February 2, 1892.

Application filed November 5, 1891. Serial No. 410,980. (No model.) Patented in England August 13, 1891, No. 13,630.

To @ZZ wwne t Hetty concern:

Be it known that I, PETER ROBINSON, tradin g as JOsEPH HIGHAM, a subject of the Queen of Great Britain, and a resident of Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Slide-Trombones, (for whicliIhave obtained Letters Patent in Great Britain numbered 13,630, bearing date August 13, 1891,) of which the following is a spccication.

My invention relates to improvements in slide-trombones; and the chief object of my improvements is to obtain echo or pianissimo effects from such instruments in addition to the ordinary tone. I attain this obj ect by the improved instrument illustrated on the accompanying sheet of drawings, in which;

Figure 1 is a side view of a slide-trombone fitted with my improvements. Fig. 2 is a plan view of the valve and its air-tubes; and Fig. 3 is a detail view of the filling-up tube, which is substituted for the echo attachment when the latter is removed.

The slide-trombone consists of the following parts, substantially of the ordinary construction, namely: the mouth-piece d, the slide h, the body c, and bell d.

The echo attachment (marked E) consists of the following parts: a piston-valvef, fitted in a tube g and connected by a tube h to a tuning-slide Il and the echo-bell j. When the echo attachment E is required, its tube g is pushed into the body-tube c, as shown in Fig. 1, and the slide b is secured to the tube g by the clip and thumb-screw Z. Vhen in posiment can be removed and the filling-up tube m (shown in Fig. 3) substituted as a means for connecting the slide b directly to the body c.

I declare that what I claim, and desire to secure byLetters Patent of the United States, 1s-

1. An echo attachment for slide-trombones,

consisting of the separate tube h and tuningtube t', substantially as set forth.

2. The combination, in a trombone, with the body c and bell d, of an echo-tube separate from the other tube and means for causing air to pass through the same.

3. The combination, in a trombone, with the slide b and echo attachment E, of the valve f, fitted in tube g and connected to said echo `attachment, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

PETER ROBINSON.r Nitnessem H. B. BAELOW, S. W. GILLETT.
