emitting ifrom the-rrozzle-,laway from the handle and the movable parts of said gauge, whereby the hands of the operator are protected from said `emitting fluid, and the danger of corroding or sticking of said movable parts is minimized.

A still further object of the invention is to pro- 0 vide a reversible seating member which may be u easily and conveniently reversed to provide additional seating surface, together with the seating .member being of such composition and construction as to enable the seating surface thereof to 5 berenewed by hammering or the like.

Another object of the invention is to provide means for contacting theseating member and the nozzle under increased pressurewithout increasing the weight of said gauge cock, whereby a positive and effective seat is assured.

Another object of the invention is to provide a p design of gauge cocks economical to manufacture l and easy to assemble.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and ,by reference to the accompanying drawing in y which an examplevof the invention is shown, and

The aperture I8' (Fig. 4) may be of angular shape for receiving an angular portion 2| of the bolt I1 whereby the same may be held against rotation. A wing nut 22 provided on the bolt makes for convenience in tightening or loosening the tension of l'the collar about a circular head 23, which is supported in said collar.

The collar is positioned upon a anged bushing Y 24, which is preferably of some non-corrosive material such as brass, and which-is assembled` upon the head with a tight fit against the annular shoulder on the circular head 23. An elongated shank 25 extending from the outer end of the head constitutes a weighted handle while upon the inner end of the head is provided a tapped hold 26' adapted to receive a cap screw 26 which holds in place circular discs 21' and 21. Disc 21 holds spring collar 20 properly assembled upon the flanged bushing 24 and upon the head 23. Disc 21 is a seating member and is of a soft metal such as a composition of Vlead and babbitt, so that when said member is engaged under pressure with the nozzle tip I2 an indented seat is readily formed in the surface of the member,

completely worn out or it is desired to replace it.;

It is pointed outthat the outer Vportion of the member 21 extends beyond the head, therebyV forming an annular protendin-g flange whichl serves to deflect any fluid, such as steam` or hot water, emitting fromrthe nozzle when the gauge ,cock is in an open position, as shown in Fig. 5.

This deflection of the emitting fluidV protects the movable parts of the gauge cock from such fluid and minimizes the danger ofsaid movable parts corroding or sticking.` Likewise, the hands of the operator are safeguarded against-burns and Y The various parts of thegauge cock may be made of any suitable material, and favorable results have been obtained with a nipple made of a composition of copper and bronze, and with the head and handle of a malleable iron casting. It is preferable that the collar 2U be made of non-corrosive spring steel, and the bolt l1 and wing nut 22 and bushing 24' also be made of a non-corrosive metal, thus assuring the expansion of the collar when the wing nut is loosened, as well as the operativeness of the gauge at al1 times. Y Y It is pointed out that the wing nut provides a singular adjustment whereby the seating member maybe freed for shifting, which together with the reversibility of said seating member and its resultant large `seating capacity assures a gauge cock of convenient operation and having a long and efficient life of usefulness.

Furthermore, the engagement of the nozzle l2 with the upper portion of the seating member and in close relation to the pivotal mounting of the collar effects a seating contact under the `maximurjn pressure obtainable from the weight of the head 23 Aand handle 25, whereby a positive and effective seat is assured.

Various changes in the size and shape of the different parts, as well as modifications and alterations, may bemade withinthe scope of the appended claims.` v

What I claim is:

1. In a gauge cock, a nipple having an axial passage, a supporting arm on said nipple projecting forwardly above said nipple, a circular head, a circular support hinged to said arm and tting about said head and in which said head is rotatable', a lsoftmetal disc fixed on said head facing said nipple, a handle projecting forwardly from said head by means of which said head anddisc may be adjusted in said support, the axis of said head and disc being below the axis of said'nipple. y

2. vIn a gauge cock, a fluid discharging nipple, an arm extending from said nipple, a handle, a seat facing thereon presented toward said nipple, a ringhinged to said arm and swivellyA supporting said handle which may be rotatably adjusted in said ring, whereby new surfaces on said seat facing may be presented to said nipple by rotating said handle in said ring.
