JAMES A. wooDBUEY, or EosTon, MASSACHUSETTS.
IMPROVEMENT IN SLI DE-VALVES.
Specification forming part of Letters Patent No. 48,61 l, dated July 4, 1865.
To all whom it may concern:
Be it known that I, JAMES A. WooDBUEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Balanced Slide-Valves for Steam -Engines 5. and I do hereby declare that the following is a full, clear, and exact de scription of the construction and operation of the same, reference 'being had to the accom- )an inodrawin s forminoa artofthissJecib g a o I tieularly as an improvement on the improvement in slide-valves for steam -engines for which Letters -Patent ofthe United States were granted to me June 21, 1864; and it consists in making the valves I) D of the vertical ports independent of each other` and with a space between them, so that they may freely expand between the vertical walls G C of the ports withoutbinding or sticking between them, thereby removing the only practical objection to the above-mentioned patented valves or to any others that may beconstructed on a somewhat similar plan.
To enable others skilled in the art to make and use my improvement, I will now proceed to describe the construction and operation of the same. Those parts which are clearly set forth in my patent of June 2l, 1864, I will not now describe in detail, but simply state that A is the cylinder, B is the steam-chest, E is the pipe which conducts the steam from the boiler into the steam-chest, F is the exhaust-pipe, and G C are the vertical walls of the ports.
In my patent of June 2l, 1864, the valves (which slide on the two vertical walls C C of the ports) consist of a sin gle continuous piece of metal, which, when the steam is rst let on to them, expanding more rapidly than the said walls C C, become, or are liable to become, immovably wedged between them. I therefore make two independent valves, D D, in place of the single one before employed, leaving, as represented in Figs. 1, 3, and 4, a space between them which will allow them to expand laterally without binding uponthe walls (l C. The two valves D D are united by means of the bar G, which is placed across the center of the top ofthe samein acorresponding groove in the under side of the top pieces, NN, which latter are confined to the valves by means of the screws m, as clearly shown in Figs. 1, 2, and 3. The bar G tits loosely in the slots in the top pieces, NN, so that the valves D D are free to expand or contract laterally between the walls C C, while at the same time they are kept in the proper relai ive position. The valverod H passes between the valves D D, as represented in the drawings, a semicircular slot being made in each of them to receive it. The valve-rod iS turned smaller where it passes through the valves, so as to form shoulders, as represented by the dotted lines in Fig. 1; or, in place of these shoulders, large washers may be put on the valve-rod, each side of the valves, thereby rendering the latter more durable and more steady in their motion.
The two valves, united as I have described, are moved precisely as though they were made ot' a single, as they are in my former patent, alluded to above, while the very serious objection to the same is entirely removed.
Having thus described the construction and operation ot' my improvement, what I claim as ne\v,and desire to Secure by Letters Patent, 1s-
l. Constructing the valves D D independently of each other and with a space between them, so that they may be free to expand or contract between the vertical parallel portwalls C C, substantially as and for the purpose described.
2. Connecting the valves DD by means of the bar G, or its equivalent, substantially as and for the purpose described.
JAMES 4A. WOODBURY.
