| Abstract:
My invention relates to engines, and is directed to improvements in the valve mechanism for the same, with a view of obtaining the most effective distribution, both on sim- pie and on compound engines. The engine herein disclosed embodies some of the features described and claimed in certain prior United States patents of mine, identified as follows, to wit: Patent No. 475,427, of date May 24, 1892, to Ellis J. Woolf, Entitled Single Cylinder Compound Engine, and Patent No. 521,278, of date June 12, 1894, to Ellis J. Woolf, entitled Engines.
Claim:
In a double compound engine, the combination with a valve-seat having a central final exhaust, port, a pair of low pressure ports, one-on each side of said final exhaust port, and a pair of high pressure ports, one external of each cooperating low pressure port and crossing the same, of a valve having outside laps over said high pressure ports, and provided with the two internal cavities c, each of which, in one position of the valve, connects one of said high with one of. said low pressure ports, and, in the opposite position of the valve, connects the same low pressure port with said final exhaust port; and whereby, the pistons will reciprocate together and are made to travel with the valve, both when the valve is cutting off admission to the high and to the low pressure cylinders. |
