Abstract
A volume control device suitable for installation on the ringer of a telephone incorporates a tone control lever having a damping element cantilevered therefrom and extending as a wing from a point of pivoting in a direction generally parallel to a frame of the ringer. The lever further comprises an arm bent through the frame to serve as a handle, and a leg extending in an opposite direction from the pivot for contacting a detent structure integrally formed with the frame. Also, integrally formed with the frame, are a ramp and a guide. The guide extends upwardly from the frame and then over a path of travel of an outer end of the wing for urging the wing downward so as to ensure passage of the wing underneath a rim of the gong during a rotation of the lever about the pivot. The ramp is upstanding from the frame at an interior region of the gong, and faces the wing so as to allow the outer end of the wing to slide up on the ramp and thereby urge a substantially middle portion of the wing against a rim of the gong for absorbing sonic vibrations thereof. The foregoing construction provides for reduced complexity of assembly, effective damping of sonic vibrations, and economical manufacture.
