SPECIFICATION forming part of Letters Ratent No. 669,880, dated March 12, 1901.
Application led June 23, 1900. Serial No. 21,344. (No model.)
To tZZ whom t may concern.: movably connected, the formation of the Be it known that I, HART HARRIS, a citizen joint between the stem and valve being such of the United States, residing at Washington, as to cause the said valve to regularly rein the county of Washington and State of spond to rotative movements of the stem 55 5 Pennsylvania, have invented a new and usewithoutlost motion. The valve-stem is freely ful Gage-Cock, of which the following is a slidable, as well as rotatable, in a cap 13, specification. which is removably secured in the upper por- This invention relates to gage-cocks; and tion of the casing and forms the top wall for the object of the same is to providea simple the chamber 2. The cap has an upwardly- 6o io and effective construction wherein the valve projecting tubular extension 14 to give a is loosely connected to and removably held long` bearing to thc stem, and the lower porby the stem and adapted to be maintained in tion ofthe said extension is provided with close relation to its seat by boiler-pressure, flat faces, as at 15, for the application of a rotated regularly to establish communication wrench or an analogous implement to secure v65 I 5 between different portions of the cock or and remove the said cap, and the exterior of grind the seat, and drawn up entirelyV clear the upper portion of the extension is formed of the seat for blowing-out operations, the with screw-threads 16 to receive a stuffingvalve-stem being freely rotatable and slidbox 17, having a suitable packing therein to able in the casing to permit the pursuance of provide a steam-tight joint around the stem. 7o zo the several movements set forth. On the upper end of the stem a handle or The invention consists in the construction key 18 is fastened for use in rotating andM and arrangement of the several parts, which lifting the same and the valve, and to provide will be more fully hereinafter described and means for establishing communication beclaimed. tween the chamber 2 and the bore 7 of the 75 25 In the drawings, Figure l is a perspective reduced extremity of the casing the valve 9 view of a gage-cock embodying the features has a port 19 eccentrically arranged therein, of the invention. Fig. 2 is a longitudinal as clearly shown in Fig. 3. vertical section of the same, showing the The particular mode of applying this type valve and stem in an elevated position in of cock to a boiler is well understood, and 8o 3o dotted lines. Fig. 3 is aperspective View of its individual operation only will be exthe valve and stem. plained, as follows: When the valve 9 is Similar numeralsof reference are employed turned bythe stem 12 a suiiicient distance to indicate corrresponding parts in the sevin either direction, the port 19 in the valve eral views. will be caused to aline with the upper ter 85 f 35 The numeral 1 designates a valve-casing minal of the bore 7, and thereby communicahaving achamber2therein and an attachingtion will be set up between the chamber 2 neck 3, formed with a bore 4, communicating and the said bore. When the valve is turned at opposite extremities, respectively, with to close the bore 7, it will be held firmly the boiler and the said chamber. The lower down to its seat by the boiler-pressure, which 9o 4o portion of the chamber 2 is regularly formed Will influence it direct, and thus prevent to produce a seat 5, having a flat bottom 6, leakage. Ifit be desired to blow outa boiler, and eccentrically opening through the seatthe valve can be completely cleared from its bottom is an outlet bore or port 7, which deseat by drawing upwardly on the stem, and, pends through the lower reduced extremity furthermore, the seat may be ground by ex- 95 45 8 of the casing for an obviouspurpose. The erting an exterior manual pressure on the seat 5 is ofV less diametrical extent than the stem and continually rotatingthe valve. The chamber 2, and therein is loosely and rotataconnection between the valve and stem is of bly mounted a disk valve 9, having an upa loose character, so that the valve may be wardlyprojecting bifurcated stud 10, in firmly seated irrespective of grit or other zoo 5o which the lower reduced extremity 11 of a substance that may collect on the bottom 6 Valve-stem 12 is fitted and loosely and reor other portion of the seat, and also the said joint permits the valve to automatically conform to any irregularities in the seat Jthat may arise from an unequal Wear. As before indicated, however, the looseness of the joint will not detract in the least from positively effecting a rotative movement of the valve to open or close communication between the several parts.
Having thus described the invention, what is claimed as new is- 1. In a gage-oook, the combination of a oasing having a seat, a Valve rotatably and removably mounted on said seat, and a valvestem slidably and rotatably disposed in said easing and havingits lower extremity loosely and removably Connected to said valve.
2. In a gage-oook, the combination of a easing having a seat, a valve rotatably and removably mounted on said seat, and a smooth valve-stem slidably and rotatably disposed in said easing and having its inner end loosely and removably attached to the valve.
3. In a gage-oook, the combination of a easing,- having steam-conveying bores therein at an angle to each other and communicating With a chamber, the lower part of the chamber being formed as a valveseat,.a valve rotatably and removably mounted on said seat and having a port therethrough, and a valvestem slidably and rotatably disposed in said easing and having its inner end loosely and removably attached to the valve.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of tWo Witnesses.
HART HARRIS.
