GAGE COCK.
Specification of Letters Patent.
Application filed August 2, 1909.
T 0 all whom "it may concern:
Be it known that I, RA YMonn .R. SnArLnv, a citizen of the United. States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful (,iage-Cock, of which the following is a specification.
This invention relates to gage cooks, in which an auxiliary valve is provided for shutting off steam to the cock in an emergency, as when the main valvc leaks.
Another object is to provide a main valve which inay be readily removed when it leaks, or becomes otherwise defective, such removal being effected without blowing the pressure from the boiler.
The invention also has for its object to provide means for rotating or grinding the auxiliary valve on its Seat to remove incr'ustations and corrosion.
A still further object is to provide a gage cock which is self-cleaning, and in which clogging up or stoppage is positively prevented.
lVith these objects in view, the invention consists in a novel construction and arrai'igcclaimed, reference being had to the drawing hereto annexed, in which,
Figure 1 isa longitudinal sectional view of the cock. Fig. 2 is a'transverse section on the line 2-2 of Fig. 1, and; Fig. 3 is a transverse section'on the line 3-3 of Fig. 1.
Referring .to the drawing, denotes the body of the cock, on the inside of which are main and auxiliary valve seats (3 and 7, respectively. The body is open at both ends, and has at one end a screw threaded portion 8, which screws into the boiler wall.
The valve seat 7 is next to the boiler, and engagcable with said seat is a valve 9, which is in the shape of a'plug, having one of its ends beveled to fit snugly on the seat, and provided at its opposite end with guide wings 10, which work-in the bore of-the body 5. \Vhen this valve is oil its scat, steam flows past the valve seat by the way of the spaces between the win s; A pin 12, extend- 4 ing across the bore of t 0 portion 8 prevents the valve from workin out when there is no pressure iii the boi er. The valve it is exposed tothe pressure in the boiler, which causes itto seat as hereinafter described.
The seat 6 is enga ed by the 'rnain"valvc 13. which is a plug aving one of its ends Patented Feb. 22, I910. Serial No. 510.788.
beveled to fit said scat. From this cud ol' a valve projects a stcmll, which is ndnplcd to enter a hole 15, made in the valve 5 l'or a purpose to be presently described. lhc stem is angular :1 cross section, and the hole is shaped acco .lingly. From the opposite cud of the vale 13 projects a stem Hi, which enters an angular opening made in the valve stem 17, a cross pin 18 passing through said parts, connecting the same rigidly together. so that the valve 13 may rotate with lllo stem 17. The valve is therefore scparably connected to the valve stem, and can be rc moved when it leaks, or becomes otherwise defective. The valve stem 17 has a screwthreaded portion 19, which engages threads in the bore of the body 5. The valvc stem extends through a packing nut 20 to the outside of said body, and is fitted with a knob or handle 21. Intermediate its ends the body 5 is fitted with a discharge nozzle V The valves 9 and '13 move to their respcd tive seats in opposite directions, and the length of the stem '14 is such that when the main valve J3 is screwed down to its scat, said stem may enter the hole 15, and when the stem reaches the inner end of said hole, the valve is pushed off its seat, this movement taking place before the main valve 13 5 seats, so that the discharge of steam or water from the cock may take place.
The auxiliary valve is to remain off its seat at all times, except when the main valve leaks, and it is desired to repair the Same. To close the auxiliary valve, the stem 17 is unscrewed to withdraw the stem-14 from the auxiliary valve 'suiliciently to permit said-valve to be seated b the boiler pressure. 'If the auxiliary valve is corroded or incrusted the valve stem isunscrewed until the stem 14. is off the inner end of the hole 15. The valve stem is then' turned alternately to the right and left, which will im-- part the same movement to the -:'1 uXiliary'1oo valve, whereby it is ground on its seat. T he pressure now being shut off from the boiler, the main valve may be safely removed for renewal or repair, and its seat may also be re aired.
etween the valve seats 6 and 7, the body has a contracted passage 23, through which the stem 14 extends, the corners of said stem being in engagement with the its corners with the wall thereof.
in ser e as a scraper for removing all sede l meme or inci'ustations tending to accumulate 1 in the passage. This scraping action occurs every time the cock is opened and closed, which makes the same self cleaning ll ha t is claimed is:--- y l. A gage cock comprising a body having a pair of valve seats, and e contracted past sage therebetween, valves engageable with i said seats, one of said valves being exposed to the boiler pressure, means for operating the other valve. and a stem on said valve engageahle with the inst mentioned valve for i 1111.. waking the same, said stem being poly l onal in cross section and extending through i the contracted passage, and engageable att valve,
es eei 2. A gage cock comprising a body having a pair of valve seats, and a passa e therehetween, valves en ageable with said seats, one of said valves eing exposed to the boiler pressure,
and a stem on said valve engageable with the first-mentioned valve for unseating the same, said-stem extending through the aforesaid passage, and having scraping edges engageable with the Wall thereof.
.ln testimony that I claim the foregoing as my own, I have hereto aflixed by signa ture in the presence of two Witnesses.
