VALVE.

Application filed July 16,

This invention relates to a valve for wind instruments, particularly horns. The invention is not confined to the valve only, but resides also in the construction whereby cooperation of several such valves maybe obtained and whereby such valves may be applied to a horn or other musical instrument. The valve may also be used generally in the mechanic arts.

Referring now to the drawings, Fig. 1 shows a side elevation of a fragment of a horn having three of my valves mounted thereon in cooperative relation,

Figure 9 is an end elevation in section taken along the line 22 of 1, and

Figure 3 is a perspective view t one of the valves.

Referring now to 2 and 3, 1 indicates an outer cylindrical casing and 2 an inner cylindrical casing closely fitting the outer one and rotatable therein The outer casing is preferably a drawn or spun piece oi? metal closed as to one end except for two openings therein, while the inner piece may be a cast ing. The inner cylinder has four openings in its front face and two in its rear, the two rear o ienings registerable with those ot the casing. Thus there are two passages 3 and 3 extending completely thru the cylinder when register is accomplished and one passage 4 which alters its direction in the cylinder and emerges trom the same face into which it entered.

From the central axis of the inner case a shaft emerges on both sides thereof, the portion emerging and the front tace being designated 5 and bearing a squared portion 5". that portion emerging from the rear being designated 6. A screw 7 and screw hole therefor is provided in the end of the shatt 5 to hold lever links 8, shown in Figs. 1 and 2 in dotted lines. Such lever links are actuated by stems which terminate in keys 10 (see Fi 1) at the top of the horn. Such stems 9 are provided with retracting springs 11 in the usual manner so that after release of linger pressure on the keys, these resume their usual position. Full pressure on the keys will produce a quarter revolution of the inner casing the outer one remaining stationary. The effect of this will be in the construction shown in Fi 1 to change the position of the openings 41., throwing these out of register and throwing the openings and 3 into register wit-h the holes in the stationary casing and with the openings of the crooks 12. It will then be evident 1927. Serial No. 206,261.

that air blown into the horn will take a longer path, that is, through the crook 12 instead of being short circuited through the passage 4, thereby producing a different tone.

In Fig. 1, it will be seen that three valves are utilized and that three changes of path of the air current are possible. Each key 10 controls one valve so that the resonating column of air behind the valve in the crooks 12 may be joined or cut of]? from the main resonating columns extending to the mouthpiece and to the bell of the horn. It will be seen that when the valve stems are not depressed, that the passages 4 0t ea ch oil? the valve bodies communicate with each other to torm a curved continuous passage joining the tube to the mouthpiece and the tube to the bell. Three major changes in the timbre of the horn are therefore possible with the construction shown. lit is obvious, of course, that instead of a construction utilizing three valves there may be any suitable number of valves used, either more or less than three. It is also permissible to utilize 0t ier known species of valves in a horn or other instrument employ ing one or more of my valves.

Having dew iii-ed my invention, I claim 1. In a valve, a cylindrical body having therein three passages, two of which. straight and extend through the said body and the third of which bends inside the body and makes its exit from the same face at which it enters, a casing tor said body, one end oi which is closed except for two holes registerable with the straight passages, and one hole to receive a bearing shaft on the body, and means for revolving the body inside the casing.

2. In a valve, a cylindrical body having therein three passages, two of which are straight and extend completely through the said body and the third of which is curved inside the body and makes its exit from the same face ot the said body at which it entered, a bearing shatt at the central axis of the said body, a closely fitting casing for the said body, the said casing being open at one end and closed at the other except for two holes registrable with the straight passages through the body and a hole to receive the bearing shaft, and lever means to rotate the valve body in the casing.

3. In a valve, a cylindrical body having therein three passages, two of which are straight andextend completely through the said body and. the third of which is curved inside the body and makes its exit from. the same face of the said body at which it entered, a bearing shaft at the central axis of the said body, a closely tting casing .tor the said body, the said casing being open at one end and closed at the other except for two holes registrable with he straight p through the body and a hole to receive the bearing shaft, and lover means to rotate the valve body in the cash 3;, a squared portion on the bearing shaft adapted to cooperate with a square hole in one oi the levers whereby a connection between the lever and the valve body may be established.
