Abstract
Abstract A support has a hollow tubular axial guide mounted on an end wall thereof. An operator is slidably mounted within the guide and spring biased in one axial direction or from normal unactuated position toward actuated position. Balls mounted within openings in the guide wall engage an annular shoulder of the operator to hold the operator in normal position. The balls are held in engagement with the operator shoulder by a cylindrical release member slidably mounted on the outer surface of the guide and spring biased oppositely of the operator and into engagement with the balls. A pair of seismic masses are pivoted to the support for swinging movement radially of the guide about axes located generally parallel of the guide axis. The masses are spring biased apart with respect to each other and radially outwardly of the guide into engagement with sidewalls of the support. Each mass includes a tapered elongated surface normally positioned in adjacent spaced relationship to a conical surface on a flange of the release member. Upon receipt of an acceleration pulse of predetermined amplitude and time directed generally radially of the guide, one of the masses moves radially toward the guide and the camming engagement of the tapered mass surface with the conical surface of the release member moves the release member axially of the guide to release the balls and in turn release the operator.
