' A construction designed to carry out the in ’ vention 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 wherein: ' i Figure lis a plan View of a device constructed i in accordance with the invention. ` v -(Figure 2 is an elevation ofthe same. ` ' . ' - 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 45 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, 50 thereby effectively closing and sealing the nozzle. y It will be noted that the nozzle engages the seat ing member in close proximity to the pivotal bolt I1, whereby the maximum pressure caused by the weight of the head 23 and the handle 25 will 55 2,124,382 be exerted to hold the member in engagement with the nozzle. , 'I‘he bolt l1 has a close sliding fit with the apertures I6, I8’ and I9’ of the bracket I5 and the ears I8’ and I9, whereby the collar and like Wise the member 2l isV held in true alignment with the nozzle. Such alignment will cause the _ i non-corrosive metal, thus assuring the expan sion 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 mem ber maybe freed for shifting, which together with the reversibility of said seating member and the member is shifted, thereby enabling a seat Y its resultant large `seating capacity assures a gauge cock of ’convenient operation and having 10 10 to be used several times with effective results. ` a long and efficient life of usefulness. The wing nut 22 provides a convenient adjust nozzle to engage the same seat indentation until ment for readily loosening the collar so that the , head 23 and likewise the member 21 may be ro Y tated to position a new seat opposite the nozzle. 15 Approximately 40 seat indentations` may be had on each side of the member andrwhen all avail Furthermore, the engagement of the nozzle l2 with the upper portion of the seating mem ber and in close relation to the pivotal mounting of the collar effects a seating contact under the `maxim’urjn pressure obtainable from the weight of the head 23 Aand handle 25, whereby a posi ber may be removed and reversed by removal of , tive and effective> seat is assured. Various changes in the size and shape of the cap screw 26. i Y different parts, as well as modifications and al 20 The seating surfaces of the member may be 20 terations, may bemade withinthe scope of the able seats on one side have been used said mem removed by hammering them until‘a suñiciently smooth surface is presented, thus permitting said member to be used over and over again until 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, there byV 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 appended claims.` v What I claim is: 1. In a gauge cock, a nipple having an axial passage,_ a supporting arm on said nipple pro 25. jecting forwardly above said nipple, a circular head, a circular> support hinged to said arm and ñtting about said head and in which said head is rotatable', a lsoftmetal disc fixed on said head ' facing said nipple, a handle projecting forwardly 30 from said head by means of which said head andïdisc may be adjusted in said support, the and minimizes the danger ofsaid movable parts ` axis of said head and disc being below the axis corroding or sticking.` 351 Likewise, the hands of ¿the operator are safeguarded against-burns and „Y The various »parts of the’gauge cock may be made of any suitable material, and favorable re sults 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 of said'nipple. y ' - ' 2. vIn a gauge cock, a fluid discharging nipple, 35 an arm extending from said nipple, a handle, a seat facing thereon presented toward said nip ple, a ringhinged to said arm and swivellyA sup porting said handle which may be rotatably ad justed in said ring, whereby new surfaces on said 40 seat facing may be presented to said nipple by rotating said handle in said ring. f l ÍWIILIAMÍE.
