Title: Pistons
Inventor: CATHERALL JOHN ANTHONY
IPC: F16J1/00
Filed: 1968-03-15
Abstract: 1,254,697. Making pistons; casting composite pistons; welding by fusion. ASSOCIATED ENG. Ltd. 6 March, 1969 [15 March, 1968], No. 12834/68. Headings B3A, B3F and B3R. [Also in Division F2] A piston is reinforced in the region of the or each gudgeon pin bore 4 by a filamentary reinforcement consisting of a metal matrix in which filaments are embedded and bonded to the matrix. The filaments may be metal wires of, e.g., stainless steel, carbon steel, tungsten, molybdenum, nickel alloy or beryllium or fibres of, eg., asbestos, glass or silica. In the light alloy piston shown in Figs. 1 and 2, the gudgeon pin bosses 3 are supported from the crown 1 by webs 8 and the filamentary reinforcement consists of stainless steel wires 11 extending from the crown, through the webs and around the bore 4. The reinforcement is formed by winding the stainless steel wire on a mandrel 12, Fig. 3, and then spraying the wire, either by flame or plasma spraying, with molten aluminium so that the winding is covered and bonded together by the aluminium 13. The composite of wire and aluminium is then cut to the required axial length and hot pressed and parted off at 14 to provide the reinforcement, which is preferably cast in to the piston. Alternatively, the reinforcement may be inserted in suitable slots in the piston casting and then electron beam welded to the piston body. The reinforcement may be formed by surrounding the filaments with powdered material and sintering the powder or, alternatively, by hot pressing aluminium-coated wires to cause the aluminium to coalesce. In a modification, Fig. 6 (not shown), in which the webs (8) are substantially radial to the boss (3), each reinforcement comprises a circular section (21A) in the gudgeon pin boss and two linear sections (21B) in each web. The sections (21A) and (21B) may be united, e.g. by electron beam welding, before insertion in the piston. In another modification, Fig. 7, the reinforcement 23 extends through each web 8 from the crown 1 to opposite sides of the gudgeon pin bore 4. In a still further modification, Fig. 8 (not shown), the reinforcement (24) is similar to those shown in Fig. 1 except that it also extends through the piston crown.

Filed: 1940-08-21
Abstract: 543,516. Machine guns. VIALE, S. M. Aug. 21, 1940, No. 13309. [Class 92 (ii)] A change-fire mechanism for automatic guns of the kind in which the striker 12 is mounted in a housing 11 slidable within the breech-block 10, which recoils with the barrel and is unlocked therefrom by relative movement between the breech-lock and striker-housing at the commencement of the counter-recoil. The housing is closed at the rear end by a slidable abutment 40 for the striker spring 13, the abutment being supported by a hook 41 pivoted at 42 to the breech-block 10. The sear 14 is pivoted at 15 to the breech-block, and a stirrup 19 is suspended from the sear tail 18 so that it may have a restricted swinging movement between abutment faces 20 on the striker-housing 11. Such movement does not operate the sear. -At its lower end, the stirrup has a toe 26 at either side of which slidable cam-pieces 32 are mounted A spring 21 presses the stirrup heel 22 against an abutment 23 on the housing 11. The abutment has a cam-surface 37 which is engaged by the cam-pieces 32. A non-recoiling transversely mounted trigger-controlled rod 24 has two noses 25, 38 and is shown in neutral position. If the rod be rocked in a counter-clockwise direction, the nose 25 engages the stirrup toe 26 and lifts the stirrup, thereby rocking the sear and releasing the striker. The stirrup moves rearwards with the recoiling parts, and on the return movement, the toe 26 meets the rear face of the nose 25 and the stirrup is rocked to the rear without again operating the sear. For automatic firing, the rod 24 is rocked in the counter-clockwise direction from the position shown. The nose 38 engages the cam-pieces 32 and forces the camsurfaces 36, 37 into operative contact. The stirrup is thereby lifted to fire the gun. On the return movement of the stirrup, the cam-pieces again make contact with the rearwardly-directed nose 38 and the stirrup is again lifted by the cam action. Firing is therefore continuous so long as the rod 24 is held in the automatic-fire position. The rod may be operated by the fluidpressure mechanism described in Specification 543,515. The Provisional Specification refers also to Specification 543,517.
