SPECFCATION iorming part of Letters Patent. No. 337,098, dated March 2, 1886.
(Xo model.)
To aZZ whom t may concern:
Be it known that l, @nantes A.Voi.nn, of Stapleton. in the county of Richmond and State of New York, have invented a new and Improved Signal-Horn, ot' which the following is a full, clear, and exact description.
My invention consists in a horn for operas tion by steam or air, constructed with an airpassage that acts to induce a strong blast, and also with an adjustable valve for varying the tone, as hereinafter described and claimed.
Reference is to be had to the accompanying' drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in -all the figures.
Figure lis an elevation of the horn; Fig. 2, a central longitudinal section through Fig. 1, line y y; and Fig. 3 is a cross-section on the line .t x in Fig. 2; Fig. l a modilication of construction, representing two valves and their corresponding openings, one on either side of the pipe inclosed in its hood or cap and provided with spiral spring adjustments to be operated by hand.
A is a tube of suitable diameter and length, closed at one end and formed with a neck, o, at the other end, for its connection to a steam or air supply pipe. The tube has a mouth, b. at one side, and below the mouth it is divided by a bridge, c, so that there are formed an upper and lower chamber, and the two chambers are connected by a narrow slit in the bridge.
Upon the outside ot' tube A. a cap or hood, d, is attached over the mouth b, so as to form a passage for air across the mouth, and in this hood is a gate or valve, e, which is hinged at one end. .et screw, f, jointed to valve c, passes out and through a nut, g, that is hung between lugs on the outside ofv the hood, whereby the moving end ot' the valve can be adjusted to and from the mouth b, so as to vary the size of the air-passage between the valve and the lip at the outer side of the mouth. Vhen air or steam is admitted under pressure to the receiving-chamber of the tube, it passes through the slot in bridge c, and thence out at mouth currents, uniting, strike the knife or edge, so that a clear and powerful sound is produced. The adjustment ofthe valve varies the sound from a shrill to a deep tone. lhere may be more than one opening and valve, and so arranged as to admit steam or air to one or both. By the induction of the auxiliary airn current, as described, much less steam is required to obtain a loud and clear note, and there is consequently a saving of steam and fuel.
This horn is adapted for use on steamboats, lighthouses. and signal-stations, and for use as a signal-instrument in the army and navy, and also as a musical instrument. The tone can be changed quickly and readily for the purpose ot' any prearranged system of signals. rllhe adjustable valve :may also be provided with a knife, and in place oi' the screw for adjustment ofthe valve a push-pin acting against a spring may be employed.
lu Fig. 4 two openings, b, in the pipe A are represented with two separat-e and independent hoods or caps, d, and valves c on the outside oi' the pipe A, the valves e having knifeedges 7i, where the currents oi air or steam unite in the separate hoods or caps, as described, and in place of the screw adjustment ol" the valves, as in Fig. l, a push-piu, lm, operating against a spring, lt, maybe employed. ln this form ofconstruction, Fig. Il, each valve c is provided with a separate hood or cap, d, to inclose it, so that each valve, with its hood or cap, is independent of the other valves and hoods on the same pipe, and notwithstanding one column'of air or steam through the pipe A may operate through all the openings simultaneously. Each valve and its hood or cap is independent, and not connected with the other valves.
lt is evident that any number of openings b, valves e, and hoods or caps d may be added, as in Fig. 4, either to increase the volume of the saine sound or note, or to produce a number of dilierent sounds or different notes in harmony, and by adjusting the valves c to increase or diminish the openings b the sound will be raised or lowered accordingly.
lt is evident that these valves e may be operated by hand, as shown, or suitable mecl1anism may be provided thereforto vary the same and hood or cap d, combined with tube A, sound higher or lower, or to produce a numhaving mouth b, substantially as described. ber of sounds or notes in harmony, thereby 3.
