VIMPROVEMENT IN COMPRESSION-COCKS, 1 I
Specification forming part of Letters Patent No. 169,873,'dated November 9, 1875; application filed September 13, 1875.
To all whom it mag concern:
Be it known that I, PETER WHITE, of St. Louis, in the county of St. Louis and Stateof Missouri, have invented an Improved Oompression -Gock, of which the following is a specification:
This invention relates specially to cocks for discharging liquids or fluids, although the construction principle is applicable also for globe steam-valves and the like, and to valvecocks in general.
This invention relates to an improved combination of parts, and their arrangement to operate in the manner now to be more fully described.
Of the drawings, Figure 1 is a sectional elevation. Fig. 2 is a side elevation.
A, Figs. 1 and 2, is the shell. This I prefer to make globular, as indicated. In the globe at is the valve'seat. The top opening of the globe is screw-threaded, and presents a faced shoulder for a Water-tight connection. B is the stem. This I construct so as to present the shoulder 12 at top, (see Fig. 1,) and against which the revolving cap acts to-lower the said stem; also, at top of stem it forms a journal-pin, 12 which passes through the bearing in cap, and is screw-threaded to receive a top screw, b (See Fig. 1.) It is against this top screw that the cap acts against in raising the stem. At bottom the stem carries the valve b as usual, but above this I form the stem partly triangular, (see Fig. 1,) to create passages for J the waste to reach the waste-tube. O is the center-piece, Figs. 1 and 2. At its lower end this is screwthreaded under its outer shoulder 0, (see Fig. 1,) and by means whereof it is secured to the shell A, so that the shoulder 0 shall come tightly in contact with the facing of the shell A, and form a perfectly-tight joint, as indicated in Fig. l. I construct the center-piece G to present a lower shoulder at 0 between which and the valve on the stem a packing, 0 forms a water-tight joint. (See Fig. 1.) Above the tube D the center-piece O has a top shoulder, 0 to receive a top packing, a, which is secured by means of a bushing, 0 fitted to screw in the top of said center-piece, as shown in Fig. 1. The .bushing 0 compresses the packing 0' round the stem, and
also against the shoulder 0 and thus forms the upper water-tight joint. Further, I form the center-piece at top to have screw-threads to receive the cap. E is the cap, made generally of the constructive shape shown in Figs.
1 and 2, fitted by its threads to engage the top the top joint. (See Fig. 1.) Finally, the center piece is secured on the shell A, and the parts thus constructed and arranged operate as follows: To admit the main pressure itis but necessary to raise the valve from its seat ct. This is done by unscrewing the cap E, which, in action, presses against the shoulder of the screw 6 and raises the stem and its valve. The stem is raised until valve closes on the packing 0, (see Fig. 1,)closing the passage leading to the waste, and thus the main pressure is allowed freely to pass. When the main pressure is to be cut off simply screw down the'stem, (by turning the cap.) This causes the cap, by its inner shoulder, to act upon the top shoulder b of the stem, and lower same, so that its valve is finally seated upon its seat in the globe, thus closing immediately and effectively the passage of the The stem and its valve fluid in the globe. thus lowered permits the waste to ascend through the passage round the stem into the waste-chamber, to be discharged from wastetube. Here it will be observed that the waste or fluid cannot possibly reach the operating parts of the screw-connection either between the cap and center-piece or journal-pin and top screw, because of the upper packing being fully compressed by'the bushing. The constructive features, therefore, shown and described are of such a nature as to fully and at all times protect the operating parts from the injurious eifects of the fluid or its sediments-an advantage of great importance.
A'lENT Orrrcn.
Further, perfect joints to close the Waste .dur-
. parts are maintained in perfect operating condition longer, requiring less repairs, and otherwise possess superior advantages over the ordinary cocks in use.
What I claim is-- The center-piece 0, having shoulder 0 upper shoulder 0 lower packing 0 upper packing vc, bushing 0 the stem B, having shoulder 12, journal b top screw b the cap E, fitted to'revolve on the center-piece, all said parts being combined, with relation to a globe, A, to operate in manner and for the purpose set forth.
In testimony of said invention I have hereunto set my hand in presence of witnesses. PETER WHITE. Witnesses:
