piarr PETER C. BURNS, OF CHICAGO, ILLINOIS.

HORN.

Application filed December 16, 1913.

To all lzei/wm t may concern:

Be it known that I, PETER C. BURNS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Horns, of which the following is a full, clear, concise, and eXact description, reference being had to the aC- companying drawings, forming a part of this specification.

My invention relates to automobile horns and has for its object the provision of a horn in which a diaphragm is suitably actuated through the agency of a striker, which striker is preferably rotatable and normally out of striking distance of said diaphragm, but is impelled into striking distance of said diaphragm as said striker reaches a position opposite the diaphragm.

I will describe one form which my invention may take more in detail by referring to the accompanying drawing, in which- Figure l is a longitudinal sectional view of a horn constructed in accordance with my invention, and Fig. 2 is a rear view thereof, the back cover plate having been removed.

In accordance with my invention, I utilize a suitable resonator 1 secured to an annular retaining ring 2, which retaining ring through the agency of screws 3 is suitably secured to a casing 4. The casing 4 has a rear cover plate 5 suitably held in place by screws 6. Within the casing 4 I have a rotatable cylindrical elelnent 7 fiXedly mounted upon a shaft 8, which shaft is rotatably held within the casing 4 and is driven through the agency of a suitable motor 9. The cylindrical element 7 has a plurality of transverse holes, in this instance five in number, within which a plurality of strikers 10,10 are mounted. These strikers are loosely mountcd within the holes provided therefor in the cylinder 7 and are prevented from falling out by means of the pins 11. A diaphragm 12 is suitably held between the ring 2 and an outwardly extending flange 13 of the casing 4. This diaphragm has a reinforcing plate 14 fastened thereto. Normally if the strikers 10, as the cylinder 7 is being rotated, are moved in their recesses to a position farthest removed from the re-inforcing strip 14, then these strikers will not touch the strip. In order to cause these strikers however to strike thestrip, and hence vibrate the diaphragm, I use a bridge 15 having a cam por- Specication of Letters Patent.

tion 16 ixedly secured within the casing 4, which cam portion is in the path of the strikers and pushes them toward the right (Fig. 1) as these strikers pass the cam portion, and thus causes these strikers to protrude from their recesses toward the diaphragm, hence to strike the re-inforcing strip 14, thereby giving the diaphragm a blow. In this manner the diaphragm is suitably actuated to sound an alarm.

From what has been described it is thought the nature of my invention will be readily clear to those skilled in the art. My invention is susceptible of many and various modifications without departing from its spirit.

Having however thus described one formv which my invention may take, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described comprising a diaphragm, a rotatable spindle, a plurality 'of strikers movably mounted in said spindle, and radially movable therein, said strikers projecting completely through said spindle, and an obstruction encountered by the extremities of said strikers farthest away from said diaphragm in the course of the rotation of said spindle adapted to propel said strikers against said diaphragm.

2. A device of the character described comprising a diaphragm, a rotatable spindle, a plurality of strikers movably mounted in said spindle, and radially movable therein, said strikers projecting completely through said spindle, and an obstruction encountered by the extremities of said strikers farthest away from said diaphragm in the course of the rotation of said spindle adapted to propel said strikers against said diaphragm, said strikers being angularly displaced throughout the spindle.

3. A device of the character described comprising a diaphragm, a rotatable spindle, a plurality of strikers movably mounted in said spindle, and radially movable therein, said strikers projecting completely through said spindle, an obstruction encountered by the extremities of said strikers farthest away from said diaphragm in the course of the rotation of said spindle adapted to propel said strikers against said diaphragm, and means for permitting a pre-determined amount of novement of said strikers through said spind e.
