The Pitcher Hand Grenade is very similar to the Battye, only different in that it is slightly heavier and having a different patent lighter. This lighter is somewhat complicated and special instructions should be given before the grenade is used.
Hand Grenade No. 7.
Ball Hand Grenade.
The Oval Hand Grenade is an egg-shaped cast iron receptacle filled with ammonal. One egg has a steel plug and the other a flanged brass plug bored centrally, to which a hollow copper tube is fixed to take the detonator. This grenade is set off by a Brock fuse and lighter[2].
[2] The Brock lighter consists of a match-head and fuse combined. The head consists of a small cardboard cup filled with friction composition and covered with waterproof paper. With this type of lighter an armlet covered with match composition is worn by the bomber on the left forearm. To ignite fuse, first pull off waterproof paper and then strike head against armlet. Time of fuse 5 seconds.
The Ball Hand Grenade consists of a cast iron sphere, 3 inches in diameter, filled with ammonal and closed by a screwed steel plug which has attached to it a covered tube to take detonator in the center of grenade. It is also lighted by a Brock lighter.
Jam-pot Bombs. In the early stages of the war it was found necessary to make bombs on the spot. The material used was generally a jam tin filled with shrapnel bullets, scrap iron, powdered glass and grass, etc. This was exploded by 2 one-ounce primers, two ounces gelignite, blastene or ammonal, and detonated by a No. 6 or 7 detonator, to which was attached a five-second fuse. The time could be regulated by length of fuse.
Mechanical Bombs. Hand Grenade No. 5, known as Mills’ Hand Grenade. Mills’ Hand Grenade No. 5 weighs about one and one-half pounds and is in constant and steady use at the front, being the best known of all grenades. It consists of an oval cast iron case, containing explosives and serrated to provide numerous missiles on detonation. In the center is a spring striking pin, kept back by a lever or handle, which, in its turn, is held in position by a safety pin.
