Abstract
Abstract A cylindrical seismic mass includes three equally circumferentially spaced conical depressions in its lower end wall which receive and seat a first set of balls seating in like mating depressions in a plate supported on the lower wall of a cylindrical housing. The upper end wall of the mass contains three equally circumferentially spaced conical depressions which seat a second set of balls also seating in an overlying first plate having like depressions mating with those of the mass. An overcenter disc spring supports the plate in engaged position with the second set of balls to in turn hold the mass in engagement with the first set of balls and locate the mass against movement laterally of the lower wall of the housing. An operator plate is supported adjacent the first plate by a disc spring in spaced relationship to a primer. When the mass receives an acceleration pulse of predetermined amplitude and time, it shifts generally parallel to the lower wall of the housing and the camming action of the first set of balls moves the mass axially or raises the mass. This movement of the mass and the camming action of the second set of balls axially shifts the first plate so that the disc spring thereof moves overcenter. The first plate then engages the operator plate to shift the operator plate axially so that the operator disc spring moves overcenter and the operator plate engages the primer. A modification includes a second plate supported by an overcenter disc spring between the first plate and operator plate.
