Abstract: 258,009. Whitehead Torpedo Co., Ltd., and Jones, A. E. June 11, 1925. Torpedoes, locomotive. - Relates to practice heads filled with water or other liquid ballast which are blown off at the end of a run when two conditions are satisfied, namely when (1) the water pressure on a movable member, due to the speed of the torpedo, has fallen below a predetermined value, and (2) a hydrostat is deflected as the torpedo sinks below a predetermined depth. According to the invention, the member held back by the water pressure due to the speed of the torpedo locks the hydrostat until the speed has fallen below the predetermined value, after which the hydrostat is free to cause the blow off when the torpedo sinks. In the form shown in Fig. 1, a flap F<1> pivoted at f<1> is swung back when the torpedo is confined in the launching tube and is kept thus by the water pressure thereon during the run until the speed falls below the predetermined value. A spring F<2>, Fig. 2, then swings the flap up, thereby moving a sector F integral with the flap from underneath the end of a lever D' pivoted at d' The lever D<1> is attached by a rod e<1> to the hydrostat E', and has a lateral projection D<x> bearing on the stem d<x>, Fig. 3, of a valve D. When the torpedo sinks below the predetermined depth after the flap F<1> has unlocked the lever D', the hydrostat is depressed and the deflection of the lever D<1> connected thereto opens the valve D. Compressed air then passes into the head A from a storage receptacle B, forcing liquid ballast out through a spring-controlled valve a<1>. Filling plugs a, C<1> are provided for the head A and receptacle B respectively. A spring- loaded non-return valve c is also provided for the receptacle B.
