REVERSlNG-V ALVE FOR STEAM-ENGINES.
SPECIFICATION forming part of Letters Patent No. 761,426, dated May 31, 1904.
Application filed October 14, 1903.
.for Steam-Engines, of which the following is a specification.
The object of my improvement is to establish a more perfect reverser fora steam-engine than the present reverser in use, and my invention will have a tendency to do away with the friction of link-motion and the complication'of other steam-reversers, such as Christophers patent, No. 474,212, dated May 12, 1892, andGilmores patent, No. 632,459, dated September 5, 1899, and my invention is asimplification of those reversers. I do not limit my reverser to any special steam-chest valve, and by making minor improvements to slide or rocking valves my reverser can be applied to any of them.
My present invention is illustrated in the accompanying drawing, in which the figure shows the construction, combination, and arrangement of valves and connecting-pipes herein described,and pointed out in the claim hereto appended.
On the drawing, A is the throttle as well as a reversing valve.
B is the exhaust as well as a reversing valve.
A and B are simply three way stop cock shells with two-way valves in them.
O and D'represent the reversing-levers and are connected to the two-way valves. With Serial No. 1"7'7,081. (No model.)
the position of levers C and D as is represented on the drawing the engine would be going ahead. Remove levers C and D to the centeriand it would close the valves and stop the. motion." Remove levers C andD to pipe F and it reverses the engine.
When the engine is making sixty revolutions and upward it reverses as if there is no dead-center by quickly moving levers C and D to reversing position.
The steamcan be checked down by moving lever 0 toward the center. Steam enters valve A on the opposite side of the valve as it appears on the drawing and passes down pipe E to the engine and is discharged through pipe F F and out through exhaust-valve B, and when reversed the steam-passage is reversed.
What I claim as my invention is In a reversing-valve device, a supply-pipe and an exhaust-pipe, valve connections between said pipes, a two-way valve in each of said connections, and valve levers for said valves in proximity to each other, whereby the valves may be worked by hand together or independently of each, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
THOMAS SULLIVAN.
