Originally built by the Britannia Company, Colchester, England, and now built in the United States by Mr. John A. Holmes, who controls the United States patents and is bringing out the general features of the English engine with modification and improvements derived from experience and the needs of a perfect motor, using the heavy oils and kerosene as explosive fuel.
In Fig. 193 we illustrate the vertical style as used for marine and vehicle propulsion. It is of the two-cycle compression type, and has but one valve, which by its peculiar construction operates as both inlet and exhaust valve. The valve is a ported piston, capped by a disc valve to hold the ports in their proper position and close the exhaust during the pressure stroke.
The crank chamber is closed, and by the downward stroke of the piston produces an air pressure that charges the combustion chamber at every revolution. It is self-igniting. The small pump seen in front, driven by a cam on the main shaft through a rock shaft and arms, with an adjusting screw to regulate the stroke, sends the oil into a small chamber seen in the extension below the combustion chamber, where it is vaporized by first heating the small chamber with a lamp to start with, after which the heat is retained by a tube extending up into the combustion chamber, when the lamp is removed and the operation of the engine becomes continuous automatically.
In Fig. 192 is illustrated a horizontal Facile engine, in which the two-cycle impulse is obtained by a differential action of the piston from its reduced size at the crank end operating through a stuffing-box, as seen in the cut. This engine has a separate valve chamber for the exhaust and inlet, which is controlled by a single valve, a combination of a ported piston and seated disc. Its operation is regulated by a secondary shaft and vertical centrifugal governor, which varies the charge.
These engines are built at present in a number of sizes, from 1 to 25 H. P., both single and double cylinder. |
