We have already called attention to the engine made by Messrs. Weyman and Hitchcock, Guildford. This firm has a large exhibit, including a portable of 22 indicated horse-power, a horizontal of 9 indicated horse-power, a two cylinder vertical engine of 15 indicated horsepower, and a small vertical engine of lj indicated horse-power for dairy work. The vertical engine, which is illustrated on page 865, is specially adapted for use in a boat for towing purposes on canals, and the like. By working one or two cylinders, two different speeds can be attained. In its general arrangement it is similar to the horizontal engines of the tame firm. In the latter the cranks are placed at 120 deg. apart, instead of being together, forming one crank, as is often the case in gas engines. By this arrangement it is sought to reduce the inertia strains; in the case of the portable engine steadiness is obtained in this way, and the tendency to vibrate backwards and forwards is greatly reduced. In all three engines the ignition tube is kept hot by a lamp in which a jet of oil is burned by aid of blast caused by an air pump, and equalized by the action of an India rubber diaphragm. |
