Bed.—The bed is of a specially strong girder form, and carries the two main bearings, which are fitted with adjustable steps of anti-friction metal, and are lubricated with automatic ring oilers. The latter dip into an oil-well below the bearing and rotate with the shaft, thus bringing up a lavish supply of oil, which lubricates the bearing and is afterwards returned to the oil-well. The same oil is therefore used over and over again until it has lost its lubricating properties.

Air and Gas Valves.—The main inlet valve and the gas valve are contained in a separate casting which is bolted to the cylinder. This system of building up in parts ensures sound castings and facilitates inexpensive renewals, should these be necessary, at any time within the life • of the engine.

Special attention has been paid to the ease with which the inlet, exhaust, and gas valves can be withdrawn for cleaning purposes. All that is necessary is to remove the blank covers immediately over these valves, as shewn in the figure, after which they can be withdrawn by hand without disturbing any of the valve gear. This arrangement gives unequalled simplicity.
