GEORGE GILMORE, OF SIMCOE, CANADA, ASSIGNOR OF ONE-HALE TO JOHN HAWTHORNE, OF SAME PLACE.
REVERSING-VALVE FOR ENGINES.
SPECIFICATION forming part of Letters Patent No. 632,459, dated September 5, 1899.
Application filed April 2 2 l 8 9 9.
To all whom it may concern:
Be it known that I, GEORGE GILMORE, machinist, of the town of Simcoe, in the county of Norfolk, in the Province of Ontario, Canada,
have invented certain new'and useful Improvements in Reversing-Valves for Steam- Engines, of which the following is a specification.
My invention relates to improvements in 10 reversing-valves for steam-engines; and the object of the invention is to provide a very rapid means to reverse the engine; and it consists, essentially, of a pair of pipes leading from the steam-inlet pipe to the valve-chest and provided with three-way cocks and intermediate exhanst and a suitable lever and arms designed to operate the three-way cocks simultaneously to effect the reverse, as hereinafter more particularly explained.
Figure 1 is a sectional view of an engine provided with my improvements. Fig. 2 is a vertical section through one of the three-way valves at right angles to the section shown in Fig. 1.
In the drawings like letters and figures of reference indicate corresponding parts in each figure.
A is the cylinder, B the piston, and C the piston-rod.
D is the inlet-port leading from the valve chest into the cylinder at one end, and E the port at the opposite end.
F is the valve-chest, which is comprised of a central enlargem entfand end enlargements G is the slide-valve, which is tubular in form and provided with end collars or enlargements 9 and g.
G is the valve-rod, which is connected and operated from a suitable eccentric on the crank-shaft.
H is the inlet-pipe, which is suitably connected to the branch pipes H and H one pipe 11 of which leads to the central enlargement f of the valve-chamber. The other pipe H leads to the end enlargement f of the valvechest.
Serial No. 714,135. (No model.)
7t is a pipe connecting the chambers 7t and h of the three-way cocks.
h is the exhaust-port, leading from the cen- 5o tral pipe h.
h and 71 are the three-Way cocks, which are provided with the d-iametrical passage-ways 2 3 and the right-angular passage-ways 4 5, leading therefrom.
I and I are the operating-arms of the cocks, which are connected together by a link 2', which is connected by the link J to the lever K, suitably pivoted and having the .usual plunger 7t, designed to engage with the quad- 6o rant L. It is by means of this lever that the position of the three-way cocks is reversed, so as to reverse the engine. In the position the engine is shown in the drawings the steam is coming through the pipe H into the enlargement f of the valve-chamber F and by the port D to this end of the cylinder. The exhaust of course passes out through the port E and the enlargementf through the pipe H, ports 4 and 2 and it out through the exhaustpipe 77?. By throwing the leverK to the opposite end of the quadrant L the position of the cooks is reversed--that is, the port 5 of the cook 77.5 is thrown into communication with the pipe H on the inner side to the valve and also into communication with the exhaust pipe 72/3. The pipe H is then made the inletpipe, and the steam passes in through it into the central portion f of the valve-chest and then through the port E, thereby reversing 80 the engine. The exhaust of course is carried through the port D and valve-chest enlargementf and pipe H Of course before the reverse and after such reverse the slide-valve derives its ordinary reciprocating movement from the cam on the main shaft,so as to open and close the ports D and E for the admission and exhaust of the steam alternately, as is usualin steam-engines of this class, in order to give the reciprocating 9o movement to the piston.
What I claim as my invention is The combination with the cylinder valvechest, ports at each end of the valve-chest commnnicatingwith each end of the cylinder and a main steam-supply pipe, of a double pipe leading from said main steam-pipe and communicating with the valve-chest, a valvecasing located in each branch pipe, a pipe connecting said valve-casings, an exhaust-pipe leading therefrom and three-Way valves 10- eated in said casings and means for simultaneously operating said valves, substantially as described.
