Abstract

Improvements in the devices producing sound calls, according to which there is a support platform provided with fixing means and provided with a snap-on lid, which constitutes a sounding board, to whose platform is fixed two parallel metallic strips, arranged for to vibrate emitting different sounds when hit, with a hammer disposed between these plates which can oscillate freely with respect to an ideal axis orthogonal to said platform and which is constantly driven by an elastic force adapted to adopt one or the other of two limit positions, determined by a corresponding set of stops and respectively close to one or the other of the said plates, finally disposing a movable member, actuable through a suitable mechanical system of transmission of movement, whose translation determines the change of the direction of impulsion exerted by the expressed elastic force on the indicated hammer, all of man was that by acting on the said maneuvering member the rapid translation of the hammer from its resting position to the opposite limit position is determined, which surpasses slightly -forcing the elasticity of the set of stops, to hit the corresponding plate, and that when leaving to act on the repeated organ, the hammer resiliently recovers its resting position, also slightly exceeding this, to strike on the other plate.
