The under-type engine which we illustrate above has been built by Messrs. Clayton and Shuttleworth, Lincoln,and embodies their most recent practice in this form of engine. The peculiarity consists in the position of the stop valve. Usually this valve is placed close to the cylinders below the smoke-box, so that the pipe above is liable to be filled with condensed steam when the engine is standing, as it forms a dead end into which it is well known water always collects. On restarting the engine this water naturally passes into the cylinder, and has to be got rid of through the cylinder cocks. By putting the valve on top of the boiler, as shown, this dead end is avoided, whilst at the same time the valve is more easily accessible for repairs, &c., than when placed in the more usual position. The steam pipe being lead through the smoke box and exposed to heated products of combustion passing to the funnel, is kept very warm, so that a supply of dry steam is insured to the cylinders. The engine illustrated is of the compound type, and has now been at work for some months with, we are informed, very satisfactory results in the matter of fuel consumption. |
