CHARLES G. CONN, OF ELKHART, INDIANA.

PISTON-VALVE MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 249,012, dated November 1, 1881.

Application led April 2, 1881. (Model.)

To all whom t may concern:

Be it known that I, CHARLES G. CONN, a

l citizen lot the United States, residing at Elkstrnments, of which the following is a specitication.-

'lhe object ot' my invention is to produce an instrument with a perfect clear-bore valve and a lighter and better valve-action than instruments of ordinary' construction. To this end I construct lny valve with a longitudinal bore, using the bottom ofthe valve-piston for one of the wind-passage apertures; but instead of connecting the adjacent valve-casini gs by a bend leading from the bottom of one valve to the bottom of the next, as has heretofore been done, lemploy a pipe connected longitudinally with the bottom ot' one valve-casing and delivering transversely into the body ot' the next, and a pipe connected longitudinally with the bottom ot' the second valve-casing and delivering transversely into the body ot' the third, as hereinafter described.

In the accompanying drawings, Figure lis a side view of a trombone-a-pston illustrating the invention. Fig. 2 is a vertical section ot the three valves thereof, the first valve being shown depressed and the other two in their upper or normal position. Fig.3 is a vertical section through the first valve at 3 3, Fig. 1. Fig. 4 is a vertical section ot' the second valve at 4 4, Fig. l. Fig. 5 is aside elevation of the central portion of a cornet embodying the invention. Fig. 6 is a side elevation ot a bass-horn embody ing the invention.

The ingress from the mouth-pipe is shown at I, and the egress to the bell at E.

A, B, and C are, respectively, the tirst, second, and third valves, and a b c their respective casings. The ingresspipe I opens into the body or central part ot' the casing a, and the egress-pipe E leads from the bottom of the third casing, c.

G H are the direct air pipes or passages communicating from the bottom of the first valvecasing, a, to the body or central part of the second casing, b, and from the bottom of the second casing, b, to the center or body ot' the third casin g, c.

The valves A, B, and C are, respectively, made, as shown, with a transverse air-passage, d, passing directly through from side to side, as in Fig. 3, or in knuckle form in and out on the same side, as shown in Fig. 4, as preferred or as the form of the piping may require, and a longitudinal passage,f, opening below through the bottom or lower endot' the valve and above through a curved port in its side, so as in the normal or upper position ot' the valves to take the wind, which is delivered horizontally through the body ot' the casing by the pipe I, Gr, or H, and deliver it downward through the pipe G, H, or E, as the case may be.

J, K, and L are the valve-bends connected with the respective valve-c;\sings for producing the valve-tones when the valves are depressed, at which time the wind, entering the casing horizontally, as before, instead of passing directly downward to the next communieating pipe, is carried through the passage d to the I'irst end ofthe valve-bends J, K, or L, and after passing through this is delivered to the lateral opening or port of the longitudinal passagef, to be conducted to the next connecting-pipe G or H or the egress E.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

The combination, with valve-oasings a b c, of the connecting-pipes Gr and H, leading from the bottom ot' one valvecasing to the body or central part ot the-next, and from the bottom ot` the second to the body or center of the third, and the valves A B C, formed with transverse or knuckle and longitudinal passages d f, the latter being arranged to communicate at their upper and lower ends with the upper and lower ends, respectively, of the connecting-pipes G and H, all substantially as shown and described.

HENRY C. Done-E, O. H. MAIN.
