[Also in Group XXVII] A cylinder head is formed or repaired so that the flame-contacted portion 86, Fig. 5, of its combustion chamber wall is freely thermally expansible relative to the remainder of the wall, e.g. via a stepped joint 87. In the repaired watercooled diesel head shown, a heat-damaged portion of the lower cylinder head wall is cut away and replaced by a portion 86 integral with a valve guide block 73 and inlet and exhaust porting 80 having outer gasketted screw connections 84. A plate having depending legs forming struts between the portion 86 and the head top wall may be incorporated. Portions 86 may be installed in a cylinder block lower wall which is itself a replacement member complete with suitable apertures for the portions. The inlet and exhaust porting may be in valve guide block portions seating separately against the head top wall via bearing ball assemblies. In another embodiment, the head side wall through which the inlet and exhaust ports open is a replacement which may be integral with or separate from a valve guide block spaced from the head top wall and bearing against screws projecting through it and against an extension valve guide block screwed into it, a loose butt joint 87 being used. In Fig. 15 a replacement valve guide block 129 is installed from above and capped by a replacement head top wall 130 having an injector aperture 148. The portions 86 may be aligned with the rest of the head lower wall by spaced screws or pins acting as keys therebetween, or by spaced spot welds or brazings. The cylinder head bottom wall may be in one piece, the thermal expansion joint being a frangible section formed by a row of drilled holes or slots through the wall, a groove in its undersurface, or a flexible connecting strip 162, Fig. 20. Such a wall may be a replacement member for an entire head undersurface and may be integral with a valve guide block and porting. In an L-head engine, Fig. 32, a replacement combustion chamber 225 is supported against a head top wall 222 by pegs 228, and has a spark plug bore 227. Alternatively a stepped joint connection between the combustion chamber and the head side walls is used, the pegs being dispensed with. An overhead valve spark ignition cylinder head is also described, having a recessed combustion chamber with a screwed-in spark plug boss which passes from the deepest part of the chamber through one head side wall.

Title: Improvements in or relating to safety gear for lifts or hoists
IPC: B66B5/20
Filed: 1934-09-21
Abstract: 447,607. Catch-gear for mine cages. JONES, H. R., 24, Porden Road, Brixton, London. Sept. 21, 1934, No. 27205. [Class 78 (iii)] In catch - gear for lifts, hoists, and the like, of the kind in which the breaking of the suspension rope causes a member to move relatively to the cage or platform and thus apply cams to the guide rails, the connecting link between the cams and the movable member is formed by a flexible extensible member. The invention is shown applied to a hoist with an overhung platform moving in a pair of vertical guides. The suspension rope 3, is connected to a sliding frame 6 which supports the platform through the agency of a spring 7 bearing against a cross-bar 22. The downward movement of the member 6, on breakage of the suspension rope, causes springs 8 to rotate the shaft 9 and thus apply cams 10 to the guides. The contacting surface of the guide may be lined with brake-material and the cam-shafts 9 supported by U-shaped straps 11 associated with resilient packing 12 to avoid shock and undue strain on the mechanism in working. Springs 16, acting directly on the cam-shaft, assist in applying the cams in ordinary circumstances and also act to apply them in emergency, should the springs 8 fail. The springs 8 and cams 10 preferably are duplicated, so that one cam is applied to each guide rail. A bar 14 maintains the frame 6 in its raised position when the cage rests on the bottom of the shaft, thus preventing the action of the cams at this point.
