Abstract

206,252. Morris & Sons, Ltd., J., Morris, J., and Morris, F. Aug. 8, 1922. Extincteurs. - In fireextinguishers in which the acid is carried in a receptacle adapted to be broken by a plunger having a vertical passage controlled by a ball valve in order to connect the inside of the extinguisher with the atmosphere at all times, the ball does not wholly close this passage as by the provision of a triangular seating b<1> for the ball. The lower face of the enlarged end of the plunger may be grooved radially so that communication with the atmosphere it not cut off in the event of the plunger resting on the acid recep tacle; or, as shown in Fig. 5, the enlarged end D' may have holes d<4>. The end may be dished as shown and may be provided with a rim. In a further modification a number of inclined holes leading to the ball seating are arranged around a central depending projection.
