ROBERT BROWN, OF NORWIGH, CONNECTICUT.
Letters .Patent No; 80,592,`dated August 4,1868.
IMPROVEMENT IN STEAM-TRAPS.
` @in tlgthultnfttm it iii tigen tvtttts @anni mit uniting niet t tige samt;
TO ALL WHOM IT MAY OONGERN:
Be it knoivnthat I, ROBERT BRWN, of Norwich,'in the county of New London, and State of Connecticut,
have invented a new and improved Steam-Exhaust Device; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referencelbeing had to the accompanying drawings, forming part of-ths specification.
The object of this invention is to so construct a steam-valve movement for the exhaust of the steam that it shall be self-acting, and moved exclusively by thepressure of the steam.-
And it consists in two disk-valves, upon a rod, operating in a partitioned exhaust-steam chest, connected with the cylinder, whereby the engine-cylinder is yrelieved of under pressure at its exhaust-end, and also of the water of condensation, in the manner hereinafter described.
The drawing,
Figure 1, represents the arrangement, in connection with a steam-engine. cylinder, the latter, with the inseam-pipes, being shown in red.
Figure 2 is a transverse section, showing one ofthe valve-seats and the steam-chest.
Similar letters ofireference indicate corresponding parts. I i A is the steam-exhaust chest, which is attached to the cylinder, and divided into three compartments, as seen in the drawing.
These compartments are marked B, C, and D. C is the chamber, to which the exhaust-pipe E is attached. The partitions F and G are thevalve-seats. 4H and I are the valves, and
J is the rod, tojvllieh the valves are attached. Each end of this chest is connected with the ends of the engine-cylinder, as seen inthe drawing. VWhen steam is admitted to the cylinder to drive the` piston to the right, as indicated by the arrow, the left-hand end of the cylinder is full of steam, whichI passes into the exhaust-cylinder and compartment B, and
closes the valve H to the seat F, as seen, while the steam from the other (or right-hand end of, the cylinder) is 'exhausting through the valve-seat G.
In the drawing, iig. 2, it will be seen that the valve-seats have oriices, z', for the passage of steam into lthe compartment C, which oriiices'are. opened and closed alternately-as the valves are moved.
When the motion of the piston is reversed, and steam is admitted into the right-hand end ofthe cylinder, the motion'and position ofthe valves willbe reversed- I will be closed and H opened.
Before the piston, vhas reached thc limit of its movement in either direction, the steam from the boiler is cut of by any suitable mechanism, and the piston completes the remainder of its stroke by the expansive force ofthe steam inthe cylinder, as in ordinary eases.
It will be seen that the pressure upon the valves I and H is the same as that upon the sides ot" theI piston i ofthe engine, and that the ends of the cylinder are relieved of the water of condensation at every stroke of the engine.
As the present invention relates only to the exhaust of the steam, and preventing the Water of condensation from interfering with the working of the engine, it has not been deemed necessary to show or `describe the slide or operating-valve movement of the engine. 1
In this exhaust-arrangement, the valve-rod J slides through thepartitiomplatcs F and Gr. The valvesH and I are attached to its ends, and are made of less diameter than the chest A, so that the occasion no friction in their movement, excepting inthe partition-plates.
I am aware oi" thepatents granted' to Allen Lapham, September 23, 14862, and to H. J. Vaerson, June 14,
i 1864, for improvements in steam-traps, but as these contain no part of my improvement Ido nottl1erefore,V
claim them.
Having thus described my invention, I claim asnew, and desire to secure by Letters Patent- 'Ihearrangement of thev steamexhaust chest A, the perforated partitions F G, the disk-valves H I, and
their common. stem, J, with relation to each other and the cylinder, as herein shown and described.
' ROBERT BROWN.
