Excerpt from Notes on Torpedo Fuzes

The cap is attached by means of a wire to the triggers.

When the torpedo is struck by a passing vessel, the cap K is knocked off, and in falling pulls out the trigger. The hammer being released, is forced up by the spring and strikes the end of the firing rod, thus exploding the cap. The entire lock should be covered to protect it from rust, and to prevent the accumulation of marine grass and shell-fish.

Application. - Apparatus of this form can only be used with buoyant torpedoes. It was used extensively by the Confederates, and with greater effect than any other variety of torpedo. It possesses the merit of simplicity, and would not be likely to get out of order. But it is best to avoid as far as possible the use of springs in torpedoes which are to remain in position any length of time.

Clock-work System. - Plate I, Fig. 4, shows the general features of this form of apparatus.

It consists of a train of clock-work carrying on the axis to which the main-spring is attached a small wheel graduated as represented, and having a recess cut in its circumference.

Fig. 5 shows the details of the exploding mechanism, N is a cylinder containing the hammer B and the spring C; D is the cone-seat, and E the cone of a musket, on which is placed the percussion cap F. G is a lever, the toe of which catches under the collar H on the hammer; I is a small stud in the lever which rests on the circumference of the wheel K, and thus keeps the hammer up. As the wheel K revolves, the recess L is brought under the stud I, which drops into it; thus allowing the arm of the lever G to descend, and releasing the hammer which is forced down on the cap by the spring G.

The wheel K can be set at will like an alarm clock, thus securing the action of the hammer at any desired time.

Application. - This form of fuze, which is in reality a time-fuze, is used in torpedoes which are intended to be exploded after a given interval of time, e. g., "current or drifting torpedoes."
