UNITED STATES PATENT CEEICE.
WILLIAM WISE, OF BAY CITY, MICHIGAN.
-VALVE FOR ENGINES.
SPECIFICATION forming part of Letters Patent No. 269,148, dated December 12, 1882.
Application led August l?, 1882. (No model.)
.To all whom yit may concern Be it known that I, WILLIAM WISE, of Bay City, in the county of Bay and State ot' Michigan, have invented a new and usefullmprovement in Valves, of which the following is a specification.
My'invention relates to a valve for controlling the admission of steam to a pair of steamcylinders for swinging the crane of an excavating-machine', and it consists, first, ot' a valve so constructed as to be capable of admitting steam to one steam-port in the valvechest while exhausting steam from the other steam-port, or ot' simultaneously opening or closingvboth steam-ports; second, in combining with a valve constructedas above acutoffvalve operated directly from the main valve.
Figure l is a plan view ofthe cylinders and the connection ofthe valve therewith. Fig. 2 is an end elevation of the valve. Figs. 3
and '4 are respectively vertical longitudinal and cross sections through the valve.
My invention is constructed and operates as follows A B is a double circular valve-chest containing the two rocking valves D E.
C is a steam-inlet to valve-chest A, and- F is a steam-portconnecting theinteriorot' valvechests A and B, and -opened or closed by moving valve D. g
G G' are steam-ports communicating with cylinders O O', and H is an exhaust-port.
S S' are the spindles which move the valves E D.
W W' are segmental gear-wheels, keyed onfto spindles S S', so that when spindle S is rocked spindle S' is rocked also.
Valve E has cut therein two steam-passages, L L', which are oi' equal size with the ports G G', and are as far from each other as are said Outside of said steam passages L L' are wings K K' on valve E, and in the center ot' said valve is an opening,`1t, cut into the face of said valve, of sufficient Width to cover the exhaust-port and one ot' the steam-ports.
O O' are two steam-cylinders, having therein pistons which are connected with the crane ot' an excavating-machine, as is more fully shown infmy application for a patent for an excavating-machine filed on the same day as this application. `By moving` the pistons in said cylinders the crane is swung, and it isimportant that the ropes or chains connecting both pistons with the crane be keptv tight, and that the engineer be able to admit steam at l will to either cylinder to start or stop the crane, or to both cylinders with equal force to hold the crane in any desired position.
When valve Eis in the position shown in Fig. 4, live steam is cut oft? from both cylinders; but a free passage of steam from one G, steam passages L L', valve chestB, and port G', thus equalizing the steam-pressurein the cylinders, holding the pistons therein in place, and holding the crane steady. When valve E isswung to the right 4until wing K passes port G, valve D opens port F, steam is admitted to cylinder C and exhausted from cylinder C', and the crane is swung.
To check the motion ot' the crane valve E Fig. 4, or may be'moved far enough to admit live steam into port G', and thenceinto cylinder 0'.
What I claim as my invention, and desire to secure by Letters Patent, is-` l. In combination with a valve-chest having two steam-ports, G G', a steam-valve, E, constructed, substantially as described, to admit steam to one steam-port in the valve-chest while exhausting steam from the other steamport, and to simultaneously open or close both ot' said steam-ports, as specified.
2. In combination with the valve'- chest B, having the two steam -ports G G', and interposed exhaust-port H, the valve E, constructed with the two steam-passages L L', the wings suticient width to cover the exhaust-port and one of the steam-ports in the valve-chest, whereby the valve can be adjusted to admit steam to one port while exhausting from the other, and to si multaneously open or close both steam-ports, substantially as described.
3. A steam-valve-which will simultaneously open both steam-ports in the valve-chest, in combination with a cut-oftl valve connected therewith, so as to cut off steam from the main valve when the latter opens both steam-ports.
4.. The combination of valve E, having spindle S, carrying thereon segmental gear W, valve D, having spindle S', carrying segmental gear W', and valve-chests A B, connected by the steam-port F, substantially as herein shown and described.
