HORN FOR MOTOR VEHICLES AND OTHER PURPOSES.
APPLICATION FILED APR. 1. 1907.

FE'LIcIEN BERTON, or PARIS, FRANCE.
HORN FOR MOTOR-VEHICLES AND OTHER PURPOSES.
Specification of Letters Patent.
Patented May 16, 1911.
Application filed April 1, 1907. Serial No. 365,688.
To all whom 'it may concern:
Be it known that I, FiiLielnN BERTON, a citizen of the French Republic, and residing at Paris, in France, have invented certain new and useful Improvements in or Relating to I-Iorns for Motor-Vehicles and other Purposes, of which the following is a specification.
This invention relates to a horn for motor cars and for other purposes, the peculiarity of which consists in the fact that it is provided with a double bell mouth through which air can freely pass, in such manner that whatever be the speed of the vehicle, the air cannot cause'any resistance to the spreading of the sound and to the development of the sound waves.
In the drawing given by way of example, Figure 1 is a front elevation of a horn according to this invention, and Fig. 2 is a section on the line A-A of Fig. 1.
The horn comprises chiefly two symmetrical bell mouths a and 6 connected at their bases by a cylindrical portion 0 in the center of which is placed the large end of the bent tube (Z of the horn or trumpet. This conduit or tube can be straight or bent to any curve.
The drawing shows by. way of example a trumpet or tube wound in a spiral, the reed c of which, producing the sound, is arranged at a tangent to the periphery of the said curve. In all constructions which may be given to the said horn, the double bell mouth a 5 forms an open conduit through which air can freely pass, so that the sound waves coming out from the tube (Z meet a current of air at a right angle to their direction and are carried away with the greater facility the greater the said current, contrary to the usual construction of trumpet in which the sound, during traveling at a high speed meeting with a very strong resistance from the air which rushes into the bell mouth, cannot escape in spite of the repeated action of the driver on the pressure ball.
In the construction illustrated, the cylindrical portion 0 connecting the two bell mouths a I) is provided with a spider 7 about the branches of which the air can freely circulate, and the central portion of which carries a socket g which is attached to the rod of any support h of suitable shape and construction.
IVhat I claim as my invention and desire to secure by Letters Patent is 1. A horn comprising a spirally wound air conduit tube, two bell mouths opening in opposite directions and arranged in the center of the spiral air conduit tube and a cylindrical central portion joining the two bell mouths substantially as set forth.
2. A horn comprising an air conduit tube, two bell mouths opening in opposite directions, a cylindrical central portion, and a supporting spider mounting in the cylindrical central portion substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FELICIEN BERTON.
