UNITED STATES PATENT OFFICE.
FRED J. STULI, OF MUSKEGON, MICHIGAN.
WATER-GAGE VALVE.
SPECIFICATION forming part of Letters Patent No. 469,336, dated February 23, 1892.
Application filed February 13, 1891. Serial No. 381,281. (No model.)
To all whom t may concern:
Be it known that I. FRED J. STULP, a citizen of the UnitedStates, residing in Muskegon, in the county of Muskegon, State of Michigan, have invented certain new and useful Improvements in Tater-Gage Valves; and I do hereby declare the following to be a full, clear, and an exact specification of my said invention.
My invention relates to improvements in' valves of water-gages used upon steam-boilers. My invention consists in the novel features of construction and combination of parts described herein, and pointed out in the claims.
In the drawings, Figure 1 is a vertical section of my valve with a broken section of the gage-glass. Fig. 2 is a .cross-section on the line fr, Fig. 1.
I make both the upper and lower valves alike, and therefore show only theV lower valve.
The valve consists of a valve-case A, having a horizontal opening through it and also a vertical opening from the horizontal opening. A main-valve stem B, having the valve l), enters the horizontal opening and is provided with a thread b', which has its female counterpart a in the valve-case A.
The valve is made steam-tight around the main-valve stem by means of a nut a and a packing, as in water-gage valves heretofore in use, and thevalve-stem is turned by means of a hand-wheelattached to it in the usual manner. Upon the horizontally extended part A of the valve-case is formed a thread a, which screws into the boiler-plate.
Removably secured within the horizontal part A of the valve-case is a tube C, provided with a vertical wall c, having a central opening adapted to form a seat c for the valve b. Within this tube are two spiders D D', (shown with three lega) which are bored centrally and form boxes or guides for the check-valve stem E. These spiders are preferably made integral with the tube. The check-valve E, formed upon or attached to the outer end of the check-valve stem E', is adapted to seat against the valve-seat c, formed at the in ner end of the tube C. A coil-spring F, havn ing one end bearing against the valve box or spider D and the opposite end bearing against the collar e, encircles the check-valve stem.
to the gageglass.
In forming the seats c and c for the main and check valves on the removable tube C the cost of repairing the gage when the valveseats have become damaged or worn out has been greatly reduced. I-Ieretofore the seat for the main valve has been formed in the main'casing, and in such construction when the valve-seat is defective or has become damaged or worn out it is necessary to supply a new casin g, which obviously is consid erably more expensive than replacing one of my tubes. Besides, in manufacturing, the valve-seats are more easily accessible for grinding and also for cleaning.
The water-glass G connects with the vertical opening of the valve-case and is attached to the case in the usual manner. A blow-off cock H of any desired construction is attached to the bottom of the lower valve-case.
The operation of the device is as follows: In the drawings all the parts of my valve are shown open or in their normal position when the water-gage is in ordinary use. The valvestcm B of both valves is withdrawn, and at such times the check -valves E remain away.
sides of the valves is substantially the same;l
but should the glass Gr break the pressure upon the check-valves'from inside the boiler will close the same and prevent the escape of water and steam from the boiler. The springs F will sustain the check-valves away from their seats when the pressure upon both sides of the Valves is equalized. When a new glass is put into the gage, the check-valves are opened by means of the main-valve stems B, which are turned in till the check-valves E are forced from their seats. The main-valve stems are then withdrawn, so as to leave the check-valves free to close in case of accident When it is desired to blow through the gage, the main-valve stems are turned in far enough to strike the checkvalve stems E and hold the check-valves E from their seats, but not far enough to close the opening through the valvecase. The
blow-off cock is then opened. While blowing through the gage the pressure on the check-valves will hold the check-valve stems E against the inner ends of the main valves B.
Should it be desired to positively close the gage at any time, it may be done by turning IOO the main-valve stems B until the valvesb are held against their seats c.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
l. In a water-gage, the valve-case A, having the projecting part A', the main Valve b, the removable tube C, adapted to t Within the part A and constructed with a seat c at its front end for the Valve b and a seat c at its rear end for the check-valve E, and the said check-valve supported and guided in said tube, substantially as shown and described.
2. In a Water-gage, the valve-case A, having the projecting part A', the main valve b, the removable tube C, adapted to fit Within the part A and constructed with a seat c at its front end for the valve b, a seat c at its rear end for the check-valve E, and spiders or boxes D D', and the said check-valve supported and guided in said spiders, substantially as shown and described.
