This type of bomb consists of a grey-cylindrical body, specially designed for anti-person-nel fragmentation, containing a bursting charge of T.N.T. and fitted with a detonator and an "always" fuze with safety device. Three varieties of the type have been discovered dif- fering in size and in the construction of the body for fragmentation. The varieties may be summarized as follows:

Fig. 34

Type "A" – This steel cylinder with substantial ends. Cylinder is surrounded by coil spring which breaks into pieces 1 inch to 2 inch long x 0.2 inch x 0.18 inch.

Type "B" – Thin steel cylinder with light ends enclosing around an inside case coil spring similar to that in type "A".

Type "C" – Double walled steel cylinder. Space between walls filled with fragments em-bedded in concrete.

The upper end piece of the cylindrical body, in each case, is fitted with a fuze adapter and the lower end piece is designed to permit of block filling.

The fuze adapter is threaded to receive the fuze and has a saucer-shaped interior to assist the functioning of the "always" fuze. On the underside it is prepared to receive the detonator.

The bursting charge consists of a block of T.N.T. recessed to receive the detonator. The block is protected by felt washers at each end and round the sides by paper packing.

The detonator consists of a brass tube 2.2 inches long with a diameter of 0.35 inches. The tube, closed at the lower end and filled T.N.T., is secured into the underside of the fuze adapter.

The fuze consists of a striker housing, striker pellet, striker sleeve, creep spring and safety rod. The striker housing is of brass and is screw-threaded externally for insertion in the fuze adapter. The upper protion of the interior is saucer-shaped, to assits in the functioning of the striker pellet. The housing is also prepared to receive the safety rod. The striker pellet is cylindrical in shape with the striker formed on the inner end and the outer end rounded to bear against the saucer-shaped portion of the housing. A transver-se hole passing through the pellet receives the safety rod. The striker sleeve carries the detonator in its lower end, which is rounded where it bears against the saucer-shaped interior of the fuze adapter. Within the sleeve, interposed between the detonator and the striker, is the creep spring. The safety rod consists of a rod carrying a screw thread near its outer end to engage a similar thread in the striker housing. The outer end of the rod carries an arming vane.

On release the arming vane is rotated by the stream of air during the fall of the bomb. This rotation unscrews the safety rod from the housing, allowing it to fall clear, thus leaving the striker and the detonator held apart by the creep spring only. On impact, if the bomb falls on its

Head – the striker sleeve overcomes the weak creep spring by its inertia and draws its detonator on to the striker. The flash from the fuze detonator passes directly into the detonator immediately below the fuze adapter, which in turn detonators the bursting charge and fragments the bomb.

Base – the inertia of the striker pellet drives the striker on to the detonator.

Side – the inertia of the striker pellet working on the saucer-shaped interior of the striker housing and of the striker sleeve working on the corresponding portion of the fuze adapter forces the pellet and sleeve together as they slide down the saucer-shaped surfaces, thus bringing the detonator and striker together.

The bomb is in a safe condition if the safety rod is in position. If the safety rod is missing, hold the bomb in the fuze down position for carrying or un-fuzing.

Unscrew and remove the fuze adapter, thus removing the detonator from the re-cess in the T.N.T. bursting charge. Alternatively, this may be accomplished by re-moving the screwed base piece and withdrawing the T.N.T. block.

Unscrew the detonator from the fuze adapter.

Unscrew the striker housing from the fuze adapter.

Remove the striker unit complete with its detonator.
