_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. _Hand Grenade No. 2_ is similar to the above, except that a special detonator is screwed in from the head, and that the striker pin, in this case, is at the bottom. The detonator having been inserted in the bomb is ready for throwing as soon as the safety pin has been drawn. _Rifle Grenade No. 3_, more commonly known as Hale’s Rifle Grenade, consists of a serrated steel case filled with T.N.T. and a composite explosive. At the bottom of the case is a brass ring fitted with wind vanes, which keeps in place two small steel retaining plugs, securing the striker. In order to prepare this grenade for firing, the steel rod attached must be put down the bore of the rifle. The safety pin is then withdrawn, the collar pulled down and the wind vane given a slight turn. The rifle is then loaded with a special cartridge containing 43 strands of cordite. When charging the rifle the bolt must be well pushed home. When the rifle is fired, the explosion of the cartridge speeds the grenade on its way and the air passing through wind vanes causes the ring mentioned above to unscrew, and the two retaining plugs to fall out. The striker is now free, and when the grenade reaches its destination and comes in contact with the ground the shock compresses the creep spring and the needle of the striker is forced into the detonator, exploding the grenade. Special screw-in detonators are supplied with this grenade, as well as in Grenade No. 2, and care should be taken not to mix the two detonators, as the Rifle Grenade Detonator is slightly longer, and if fixed in the wrong grenade will cause premature explosion and much sadness. These grenades have an accurate range of from 250 to 350 yards. IGNITION BOMBS. The following bombs come under this heading: Hand Grenade No. 6.--Grenade light friction pattern.
