WATER-GAGE.
SPECIFICATION forming part of Letters Patent No. I750,539, dated January 26, 1904. Application filed December l2, 1903. Serial No. 184,865. (No model.)
To a/ZZ whom t may concern,.-
Be it known that I, NIooLAI H. HILLER, a citizen of the United States, residing at Carbondale, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements inWater-Grages, of which the following is a specification, reference being had therein to the accompanying drawings.
rIhis invention relates to glass gages for indicating the level or height of water or other liquid in steam-boilers or other vessels. Heretofore in this class of gages the passage between the gage-tube and the vessel to which the gage is attached has been supplied with a ball check-valve arranged therein to normally permit a free opening therethrough and to automatically close the passage in the event of breakage of the glass tube or during'the replacing of the tube and also in conjunction with this ball check-valve an independent spindl'e-valve operated by an exterior hand device to positively open and close the passage, the spindle of this valve being projectedbeyond the same to contact with said ball valve for the purpose of forcing the ball valve from its seat and also to eifect this without closing the spindle-valve and wherebyA the passage between the boiler and the glass tube is kept open. With this device the ball valve and independent spindle-valve could not both beseated at the same time to insure perfect safety while replacing a glass tube.
In the present invention both valves may be positively seated at the same time or separately, as desired. To accomplish this result, the invention consists in rendering the inner projecting end of the spindle-valve adjustable longitudinally to permit the respective valves to seat at the same time or to operate both valves to open alternately or simultaneously, as desired.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side View, made partly in section, of the complete gage attached to a boiler or other vessel; Fig.` 2, a vertical section of the upper fixture on the line 2 2 of Fig. 1, and Fig..3 a horizontal section on the line 3 3 of Fig. 1.
In each figure the corresponding numerals of reference indicate the same parts.
4 4 represent the upper and lower `fixtures for holding the glass gage 5 and containing the valve devices, the fixtures being connected with the vessel 6 by means of threaded nipples 7 7. The respective fixtures and valve devices are similar in detail except that the opening 8 in the upper fixture for the insertion or removal of the glass tube is of larger size thanthe corresponding opening in the lower fixture.
In the sectional view Fig. 2 a relative arrangement of the valve devices is shown whereby the passage to the glass tube is unobstructed.
The packing-boxes and screw-caps for securing the glass tube and the valve-spindles are of the ordinary construction.
9 represents an enlarged chamber at the inlet of the fixture, in which a ball-valve 10 is placed and sufcient space surrounding the ball-valve allowed to normally permit a free passage through the chamber and a longitudinal movement of the valve; This ball-valve is supported by guide-bars which maintain it in position to allow a free passage and acts automatically to close the passage at a seat 12 when the glass tube is broken or removed, the ball being forced outwardly and seated by the boiler-pressure.
The passage leading from the ball-valve chamber 9 to the glass tube is also fitted with a valve 13 and seat 14, this valve being operated positively by its screw-spindle 15 and hand-wheel 16.
The spindle 15 of the valve 13 incloses a threaded rod 17, which projects beyond the valve and also at its outer or opposite end beyond the hand-wheel 16. AThe outer end of this rod passes through a stufEng-box and is squared to facilitate its rotation. The rod is adjusted to project beyond the spindle-valve 13 a distance to either force the ball-valve away from its seat and permit an open passage through both valve-seats or retracted to permit either valve to positively close alternately, as desired. To determine the amount of movement of the rod 17 to such a position as to effect either purpose, an indicator 18 is fixed in the hub of the hand-Wheel 16, as shown in the respective figures.
What I claim, and desire to secure by Letters Patent, is-
In a device of the class described, the combination with the valve-casing having a passage therethrough and oppositely-disposed valve-seats in said passage of a ball check- Valve adapted to cooperate With the inner seat; a'controlling-valve device cooperating With the other seat; a movable rod attached to the controlling-valve device, and means for adjusting said rod longitudinally with relation to the controlling-valve, substantially as and for the purpose set forth.
In testimony whereof I aiix my signature in presence of two Witnesses.
