Nl PETERS. PHOTO-LITHOGRA^HER. WASHINGTON, D. C,
UNITED STATES PATENT OFFICEo SAMUEL TRUMBORE, OF EASTON, PENNSYLVANIA.
IMPROVEMENT IN SEALS FOR HYDRAULIC MAINS 0F GAS-WORKS.
Specification forming part of Letters Patent No. 113,946, dated April 18, 1871.
To all whom it may concern.'
Be it known that I, SAMUEL TRUMEORE, of Easton, in the county of Northampton, State of Pennsylvania, have invented certain Improvements in Gas Apparatus, ot' which the following is a specification.
My invention consistsvmainly of the combination,witl1 thedippipeand hydraulic main ot' gas apparatus, ot'a valve so constructed and arranged in respect to the said dip-pipe and to the tar-level in the main that it shall prevent the passage of gas when in its seat without having any tendency to adhere to the latter, owing to the presence ofthe tar; and my invention further consists ot' a tube extending below the tar-level and otherwise arranged, as hereinafter described, so as to serve as a substitute for the stuingbox, which would otherwise have to be used in connection with the valve-rod.
In the accompanyingdrawings,Figure lisa transverse section ot' the hydraulic main ot' gas apparatus with the dip-pipe and valve arranged in accordance with my invention; and Fig. 2, the saline, showing the valve raised.
A represents a portion of the hydraulic main of gas apparatus; B, a vertical dip-pipe ex-v tending down into the same within a short distance of the tar-level x, and G a pipe leading from the retorts and communicating with the upper part of the dip-pipe. The dip-pipe is surmounted by a cap, a, from which is suspended a tube,D,ol' small diameter, which extends downward through the center of the said pipe toapoint below the tarlevel,and through this tube passes a valve-rod, b, attached to and operated by a lever, e, which is hung to a standard, f, or other fixed object. l.
To the lower end of the rod b is attached a hollow cylindrical valve, F, which is contained partly within the lower end of the dip-pipe, and is adapted to an internal seat or ledge, li, formed in the latter. The valve is maintained in its seat by the action of a spring, i, connected to the operating-lever, as seen in Fig. l, and when in this position the cylindrical portion j of the said valve will project below the tar-level and prevent any back-pressure of gas from the hydraulic main toward the retorts during the charging of the latter. When the valve is raised from its seat, however, after the charging ot the retorts, its cylindrical portion will be lifted above the tarlevel, and the gas as it is exhausted from the retorts can pass reelythrough and around the said valve into the hydraulic main A, as indicated bythe arrows. The valve is fitted so loosely into the lower end of the dip-pipe as to prevent it from gumming orsticking fast to the same, owing to the presence of the tar, and it is of such construction as to eii'ectually seal the lower end of the dip-pipe and prevent any passage of gas during the charging of the retorts, and its construction is also such thatit shall ol'er as little resistance as possible to the gas when it is raised from its seat.
As before mentioned, the tube D, which surrounds the valve-rod, extends downward to a point below the tar-level. The tube, when thus arranged, electually prevents any escape of gas around the valve-rod, and thus serves as an economical substitute for the stuffingboX, which would otherwise have to be arranged in the capa. of the dip-pipe for the passage ot the valve-rod.
I claiml. The valve F, constructed substantially as described, and arranged within the dip-pipeB and hydraulic main of gas apparatus in respect to the tar-level in the said main, substantially as specied.
2. The tube D, surrounding the valve-rod l), extended to a point below the tar-level in the hydraulic main, for the purpose specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
SAMUEL TRUMBORE.'
