SELF-ADJUSTING WATER-GAUGE CONNECTION.

Application filed December 5, 1924. Serial No. 754,077.

- eye judgment rather than by accurate measurement, the result being` that the axes of the tapped holes, with which the opposite ends of avwater gauge are connected, are frequently disposed in either diverging o r converging directions, or else, the boiler |s tapped at points greater or less than the distance required for the particular type ot gauge. When this occurs, and when the water gauge is coupled at its upper and lower ends with the boiler nipples, the water glass is subjected to lateral tension, with the result that'the glassris either broken in the installation thereof, or becomes broken at some subsequent time due, tov expansion or contraction. Furthermore, the glass under lateral tension kcan not be given a water and steam tight connection at its upper and f lower ends.

It is an object of the present invention to provide means of a simplified and improved construction whereby the water gauge may be properly installed upon the boiler without danger of breakage oi the glass either in its installation or at subsequent times `from expansion or contraction, regardless of the fact that the boiler nipples may be disposed at improper angl-es or improperly spaced apart.

A further object is to provide improved packing means in connection with water gauges to compensate for inaccurate disposition of boiler nipples, and also to permit of the glass being properly applied and maintained in proper steam tight connect-ion without tension at its respective ends.

lith these objects in view, together with others which will appear as the description u proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and particularly pointed out in the claim.

In the drawing:

Fig. 1 4is a side elevation of a water gauge structure embodying my invention, the connection between the gauge ends and the boiler nipples being shown in section,

Fig. 2 is an enlarged end elevation of one of the improved packing members or gaskets,

y Fig. 8, is a vertical sectional view taken through thev said member,

Fig. 1 is a similar view of the cooperating packing element, and

Fig. 5 is an end elevation of the element shown in Fig. 1.

The boiler `6 is tapped at 7 to receive the v nipples 8 to be connected'to the gauge, and these nipples are carried by valves 9. of the ordinary construction and for purposes well known. The tapping of the boiler at inaccurate distances for the gauge to be used, or

with the taps disposed at improper angles, vcauses thenipples or pipes 8 to be disposed at angles as illustrated, probably kin slight exaggeration, in the drawing. In the drawing, the position of the pipes or nipples y8, if the tapping otv the boiler was on a true center, is indicated by broken lines at A, `in order to more clearly show the inclination 'of the nipple.

The water gauge may comprise the usual upper and lower elbows 1() and 11, between which extends the water glass 12, which is connected to the said elbows by steam tight packing glands, and the glass may be inserted through the upper elbow by removing the plug 13 carried thereby. The lower elbow is equipped with the usual pet cock 141. The glass 12 is protected by a series of rods 15 disposed parallel to the glass and con` nected at their ends to the flange members 16 arranged parallel to each other upon the upper and lower elbows.

Each of said flange members is provided with an outstanding annular'boss 17 concen tric with the opening in its respective elbow to communicate with the water glass. Each boss has threaded exteriorly thereof a packing nut 18.

Each of the elbows 10 and 11 has an angun larly disposed pipe section 24 thereby connected to the globe valve pipe or nipple carried by the boiler. The outer ends of said pipe portions are enlarged and are threaded exteriorly as shown to receive the internally threaded nut members 25. Each of the an nular bosses 26 thus provided includes an internal plane seat 27 surrounding the bore of the pipe, and which receives a member 22 of the cooperating packing. The cooperating packing members or elements comprises an annular member having an interior passage 2l, said member 2O is of substantially truste-conical form Vaafidfis formed of a compressible material. The other element comprises an annular member 22'having a central aperture and inclined Walls 23 upon its interior, corresponding substantially to the inclination ofthe exterior Walls of the element 20. The nut members 25 of the gland are loosely carried by the innerends of the nipple or globe valve pipes 8, and this inner end of the pipe has an out-turned flange 28 to retain the nut in position,` and to be 4engaged by the inwardly extending flange 29 of the nut section 25. k'It Will be noted that the outer tace` of the nut member 25 defining the opening through Whichthe valve pipe extends is bevel-led or cut away as at 30, permitting the said pipe and nut to assume various angular positions With respect to each other.

This construction permits of the boiler nipple members being connected to the pipes 24 of the gauge lWith the assurance oi a steam and watertightconnection regardiessotL angular variations Which may exist between these members. By'tightening the nuts 25,tl1e flange 28 is drawn inwardly against the packing element 20,forcing the inclined face thereol tightly against the similarly inclinedcooperating face of element 22, ythus Wedgi'ng these elements tightly together so asito be proof against leakage. The flexibilityv or pliability offthe packing permits of this joint being properly effectedwithout-strain u ponthe pipe mem* bers-24 ofthe'- gauge, andl Without danger of distortion of the gauge glass l2.

From. the foregoing it is apparent that I have provided packing elements for use in connection -vvith `Water gauges and gauge mountings which are of extremely simple constructien,:whichl may be assembled properly Without the exercise of special skill or knowledge, and which Wilflffaccoinplish the desired 'resuits in/ -a -facilef manner.

IHaving thus described my invention, I claim:

'In' `an vadjnstablei union fora' vwater lgauge structure,l pipe sections approximately -alined with each other, the section 'adjacent the gaugehaving afau'cet end: provided Withfa 'cylindrical' counterbore defining a piane seat surface, the other 'pipe section having a anged spigot-fend presenting a plane end face, apair of'ccmpressible packing elements nested in the said counterboreand presenting complementary conical abutting surfaces and plane"end"'surtaees,'and a 'union net engaging said 'faucet end, and having an end flange embracing the lrear "of the flange on the fspigotend to clamp the'latter into sli'ding' engagement vWitlrtl'ieplane end surface of the 'outer packing element.
