Although I have shown one form of mechanism embodying my invention, it is ob vious that various changes within the skill of the mechanic may be made in said mechanism without departing from the spirit of the invention provided the means set forth in the following claims be employed.

I claim as my invention:-

1. A horn comprising a me al'diaphragm having annular corrugations therein, an actuating member secured to said diaphragm, a movable disk having radial ribs or flanges thereon adapted to engage with said actuating member and vibrate the diaphragm, and means to actuate said disk.

2. Ahorn comprising a diaphragm under tension, an actuating member secured to said diaphragm comprising a plug and a passage therein with a restricted opening at one end to form a ball seat, a ball in said passage and means for securing said ball in said passage to cause a segment thereof to project beyond the end of the plug, a disk provided with means engaging said proje ing segmentof said ball to produce to azxl fro movement ofthediaphragm and means for moving said disk.

3. A horn com ')rising a metal diaphragm under tension having annular grooves there in, an actuating member secured to said diaphragm and comprising a ball rotatable in said member and held against displacement with respect thereto, a disk having radial ribs'on its surface to engage with sa' ,1 actuating member, a driving gear for rotating said disk, a driving pinion, means for aetuating said driving pinion, and a clutch mechanism between said fpinion and driving gear substantially as described.

1t. In a device of the class described, .meehanism for actuating a diaphragm horn comprising a diaphragm actuating mem ber formed of a disk provided with diametrically disposed diaphragm contacting ribs and provided with open spaces between adjacent ribs, a shaft supporting said disk centrally thereof, a pinion fixed to said shaft and constituting the end member of a train of gears, a second member of said train meshing with said pinion, a manually actuated reciprocating member and means between said reciprocating member and said second gear train member for converting the reciprocating movement of said handle into continuous rotary movement of said disk, said mechanism being freely rotatable.

5. In a mechanism for actuating a diaphragm horn, a diaphragm engaging member comprising a shaft, a disk mounted on said shaft one flat surface of said disk being provided with radial grooves to form ribs beveled in'sectionand of varying width. said ribs being spaced apart and adapted to engage a projection from the diaphragm of the horn to vibrate said diznhragm and means for rotating said disk a out an axis perpendicular to said grooved face.

This specification witnessed this 12th day. of Dec. A. D. 1910.
