There are three kinds of bombs: (1) percussion; (2) ignition;, and (3) mechanical. It is not possible to describe every bomb in use under these three headings, but the most typical are selected for description, although it does not follow that they are all in use at the present time, but will give a fairly good idea of what is required.
1. Hand Grenade No. 1.
2. Hand Grenade No. 2, formerly known as Mexican Hand Grenade.
3. Rifle grenade No. 3, formerly known as Hale’s Rifle Grenade.
Hand Grenade No. 1 consists of a brass case screwed on to a block of wood, to which is fixed a small cane handle about half way up the case. Outside it is a cast iron ring serrated into 16 parts. The upper end is covered by a moveable cap with a striker pin in the center. On the cap are the words “Remove,” “Travel,” and “Fire” in duplicate. These are marked in red and can be made to correspond with red pointers painted on case. To prepare a bomb, turn cap so that pointer is at “Remove,” take off cap, insert detonator in hole and turn it to the left until the spring on the flange is released and goes into position under the pin; replace cap and turn to “Travel,” which is a safety position. When the bomb is to be thrown, turn cap to “Fire” and then remove safety pin. This bomb explodes on impact, and to insure its falling on the head, streamers are attached. Care should be taken that streamers do not get entangled. The bomb must be thrown well into the air.
