Title: Improvements in or relating to armour-piercing shells
IPC: F42B12/06
Filed: 1937-10-23
Abstract: 582,660. Projectiles. HATFIELD, W. H., and BRIDGE, J. F. Oct. 23, 1937, No. 28967. [Class 9 (i)] An armour-piercing shell is fitted in or on the head or cap (when a cap is provided) with one or more pieces of a sintered hard metallic alloy comprising a hard metallic carbide bonded by a metal or alloy of lower melting point, for the purpose of improving the armour-penetrating properties of the shell. The metallic carbides preferably employed are those of tungsten, tantalum, titanium, molybdenum, chromium and vanadium and these are bonded by metals or alloys of lower melting point, such as cobalt, nickel or iron. Examples of the method of preparing these alloys are described in Specifications 477,181 and 481,805, [both in Group II]. Numerous methods for insertion or attachment of the one or more pieces of hard metallic alloy are described and shown, the shell nose in all cases being indicated at 1, the cap at 2 when provided, and the hard metal insert or inserts at 3. Thus, as shown by way of example in Fig. 1, in which a cap of usual construction is used, the insert is located immediately over the nose of the head of the shell, being recessed into the body portion of the cap. If desired, the nose of the cap may be made hollow. Alternatively, the insert may be in two portions located on opposite sides respectively of the head, with each portion either recessed into the cap as before or inserted in the head of the shell. According to a further modification, the cap may be in two portions, one of which may be hollow, the subdivision being transverse to the length of the shell and the metal insert or inserts being located at or close to the subdivision. Fig. 16 shows an example of such a construction in which the cap is subdivided into a hollow nose 4 and a solid portion 5, the insert 3 being in this case in the form of a ring. According to other forms of the invention, the metal insert may be recessed into the exterior surface of the cap, as shown for example in Fig. 19, or inserts may be fitted at or near both the interior and exterior surfaces of the cap. Fig. 24 shows a construction in which the hard metal alloy is in the form of a ring around the nose of the cap, a pellet 6 of hard metal alloy being also embedded in the cap. In the case in which the shell is not provided with a cap, a hard metal insert may be fitted over the head of the shell as shown in Fig. 25. As an alternative or in addition to this arrangement, the hard metal alloy may be applied to the nose of the shell as a ring.
