citizen of the'United States, residi at'Harte ford, in the county of Hartford an State of Connecticut, have invented a new and useful Improvement in Horns, of which the'followis a specification.
biles and motor boats, for the purpose of givhe object o the invention is to'produce a compact and neat horn, that is sim 1e and cheap to manufacture, and that wil give a full, strong tone when blown, regardless of the direction of the wind orthe speed at which the vehicle, to which the horn is attached, is traveling.
Warning horns of this character have customarily been constructed with one or more flaring or hell mouths that project fromthe center, or the periphery of'a convolute bod These flaring mouths, which have commonl been supposed necessary to insure a full toned sound, notonly project outward in such manner as to occupy considerable space, and which are in appearance more or less clumsy and bungling and require an unnecessary amount 0 catch the air currents, and revent the full SOlIlCl produced by the reed rom being emitte an automobile traveling say forty or fifty miles an hour catches the air and causes it to back into the horn against the reed with greater pressure than can be roduced by squeezinglthe bulb usually emp eyed for this class of orns, and consequently the horn will not emit the necessary sound when de sired.
The horn which embodies present invention is coiled so that the outlet is at the center, and is of such shape and is so protected that air will not be blown into the tube when the vehicle with which it is used is in rapid motion, allowing a full volume of sound to be emitted when the bulb or other source of air so ly is operated and the reed sounded.
igure 1 of the accompanying drawings shows a side elevation of one form of horn metal in their construction or instance, a bell mouthed horn onthat embodies the invention.
, v Fig. 2 shows an edge'elevation of the same.
. The body 1 of the horn, which may be made.
of any convenient rhetal, preferably thin brass, is formed of a taperin tube wound into'a helical coil with the sma ler end at the I pel i iphery and the larger end at the center.
e smaller or inlet end 2 of the horn-is designed to receive a tube 3, which contains a common form of reed, and which is arranged for the attachment of the end of the tube which leads'from the bulbor other common means for supplyi air for blowing the horn.-
The lar e1 or out et end 4 of the horn, inn
stead of eing turned outwardly and provided witha projecting bell or flaring mouth,
as is the common horn, is left in the plane oi the coils and is tapered down so as to forma conical head 5.. This head is perforated; preferably by slots 6, although of course.
other forms of perforations could be used without departing from the invention.
A horn constructed in this manner is comteract the'force of the air that is forced out' when. the horn is blown.
The invention claimed is: 1. A horn consisting ofa tapered conv0- lute body with the smaller end of the body at the periphery and the larger and of the body at the center, said larger end having an ovoid perforated head in the plane of the coils, substantially as specified. p
2. A horn consisting of a tapered convolute body with the smaller end of the'body at the periphery and the larger end of the body at the center, said larger end terminati in the plane of the coils in a rounded head to at is=provided with slits, substantially as spcci-c. fied. l I
3. A horn consisting of a tapered convo in a rounded head at the center, -sgid head lying in the plane of the coils and" rovided 10 with perforations on both sideslof t e plane of the coils, substantiall as s ecified;

lute body with the smaller end ofthe body at the Eeriphery and the larger end of the body 7 at t e center,'sai'd larger end terminatin in the'plane of the coils and provided with s its, 5 substantially as specified. l
- 4. A horn eonsisti of a tapered convo- Witnesses: lute body with the sma ler end of the body at HARRY H. WILLIAMS, the periphery and the larger end terminating I JOSEPHINE M. STREMPFER.
