CAMPAIGN-HORN.

SPECIFICATION forming part of Letters Patent No. 455,671, dated July 7, 1891. Application filed March 13, 1891- Serial No. 384,945. lNo model.)

T0 whom it ntwy concern/.-

Be it known that I, WILLIAM SELLERS, a citizen of the United States, residing at Haverhill, in the county of Essex and State of.

side of which is secured a shortmetal cylin der that extends a short distance over the mouth-piece, the outer end of said cylinder being formed with two half-round circumferential grooves, to which issecured an elastic packing and an outer cylinder of larger diameter than the cylinder on the horn, which works in said outer cylinder, an air-tight joint being formed between the two cylinders by the elastic packing, as hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side view ofa campaign-horn embodying my invention. Fig. 2 is a longitudinal section through the same. Fig. 3 is a side view of the horn, its cylinder, and elastic packing. Fig. 4 is a view of the elastic packing before it is secured in position.

A represents the horn, to which is secured a cylinder B, closed at its end I), where it is secured to the horn. Said cylinder extends a short distance over the mouth-piece a to protect the same. The outer end ofthis cylinder is formed with two circumferential grooves c c, to which an elastic ring 0 is secured by two cords or wires (Z (7,. This elastic ring is first secured by one of the cords or wires (l and is then pushed on the cylinder B until its central portion projects in a semicircle c, as shown, (see Figs. 2 and 3,) when its outer end is secured by the other cord or wire (I.

F is an outer cylinder closed at one end f. The diameter of this cylinder is greater than the cylinder B and just that or slightly smaller than the projecting portion e of the elastic packing O. The cylinder B is inserted into 5 the cylinder F, and the elastic packing e forms an air-tight joint between the two.

To operate the horn, the horn A is held in one hand and'the cylinder F in the other. Then by drawing the cylinder B nearly out 5 of the cylinder F air is drawn into the cylinder F through the horn A. Now by forcing the cylinder B back into the cylinder F the air is compressed and is forced through the reed or mouthpiece a of the horn, thereby 6i producing sound, the air being compelled to pass through the said reed or mouth-piece, as it cannot escape between the two cylinders by reason of the elastic packing on the cylinder B. 6

That I claim as my invention is l. The horrrA, having the cylinder B se-' cured thereto, the end of said cylinder being formed with two circumferential grooves c c, the elastic packing O, secured thereto by 7 cords or wires (Z d and projecting in a semicircle beyond the sides of said cylinder, and an outer cylinder F, closed at one end f, the cylinder B working in the cylinder F, and the packing O forming an air-tightjoint between the two cylinders, substantially as Set forth. 7

2. The ring 0, of suitable elastic material, in combination with a horn havinga cylinder attached thereto and free to slide in an outer 8c cylinder, the said ring being secured to the end of the inner cylinder and projecti'ngin a semicircle, so as to form an air-tight joint between the two cylinders, substantially as shown and described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 2d day of March, A. D. 189i.

WILLIAM SELLERS.
