Gema/ral Description.
The body of the cock consists of a tubular casing, A, the screw-stem a of which 'projects through an openingv in the head of a boiler, (shown by4 dotted lines`,) and is securely attached to the same by a nut, b, suitable packing being employed to insure a tight joint.
The casing A has also a screw-stem, a', and an enlargement, c,which isl of a hexagonal or other suitable form, to receive a wrench. v
B is a'rod, (partly solid and partly tubular, as explained hereaften) which passes through the interior of the casing A, and through a cap, D, screw-ed on to the stem a', the said 'rodhaving on its inner end, within the boiler, a valve, e, which is adapted to a seat, j', formed at the end 'of the stem a.
' The rod B also passes through a mass of packing, h, contained in a stuffing-box formed within the casing A, which prevents leakage round the rod B, a follower, i, being forced against the packing by the screw-cap D.
F is a lever, hiuged'to au arm, j, on the cap D, and arranged to pass through an opening in the outer end of the rod' B, so that the lever forms a convenient medium for moving the rod B to and fro in the casing A.
Extending part way through the rod B, is a central longitudinal passage, It, communicating, at its outer end, with a nozzle, l,- and at the inner end of the said passage, are one or more transverse openings, s, which,
when the rod is moved inward, as shown in fig. 3, oom- 4municate with the interior of the casing A, which is enlarged from the valve-seat to a point/near the stuffing-box,.so that when the latter is moved to the position shown in iig. 3, steam or water can pass through the annular space between the rod and casing into the discharge-nozzle l.
To close the cock, all that is necessary is to slide the rod B outward by means of the operating-lever F, until the opening or openings s, leading to the diseharge-oriice, are covered by the packing h. (See figs. 2 and 4.)
By thus using the packing as a medium for cutting off all communication between the interior of the boiler and the discharge-orifice, all leakage is eiiectually preventedan important point, as dependence cannot always be placed on the efficacy ofthe valve e for this purpose, the valve being relied upon only for the purpose of preventing the outward escape of steam or water, when it becomes necessary to repack the stuifing-box, when there is a pressure of steam within the boiler.
I do not claim broadly a steam-valve, closed by the force of the internal pressure, nor a hollow rod, receiving and discharging the fluid, as shown; ,but
I claim as my invention, and desire to secure by Letters Patent-4 l The casing A, adapted for application to a boiler, having a valve-seat at its inner end, and a packing, h, in combination with the sliding rod B, its valve e, and passages b and k, and with the lever F, connected to a projection on the easing, and operating as set forth.
In testimony whereof, I have signed my name to this speeiiication, in the presence of two subscribing witnesses. Y y SAMUEL BLACKMAN.
