'.lliis: invention. relates. tof an=y inspectn plig': or device .whereby itj is possible to determine, the-Condition or the interiory the'wvater 'column or other Water container Without breaking any. of the .usualv connections. .Y One object therefore isztof.- provide inspection-.means for a. Water column.v iinother.. object. is tir provide an` inspection meansfor a' water column in conneetionjwith boiler and.. gauge. whereby, an. inspection may be made of the interior of' the Water. column andL whereby a; sample of Whatever sediment hasbeenv deposited maybe readily With-dranni-:x therefrom. Other objects will^ appear.: from time to, time throughout the specification. and claims. l

The use 'and operation Oijmy4 invention are asffolloWs: .V The parts are assembled asshown and Water is conducted to the Water column; so

that the inner end of the threadedx portion .the plug ID3-corresponds generally with the interior yofthe Water Vcolu-n'un and" thus the outer orbottom ends ofthe pockets-D3* are I on a line with the interiorl ofthe Watercol-iumn. K i.

, Buring theV operationqofx the devices;n with which;v the Water: column., is associated the Water;` of course passes more or less` constantly through the column. In the course of time various sediments andl sol-id matters vvillbe deposited out of the Water and Vwill llodge,inthe-Water column orl adhereY toits Walls, or otherwise become more orless'per-r manently iffxed Within it. This makes it necessary to clean out the Water column.` Heretotore, in order to do; this, it has' been necessary to drain the boiler beljovv the bottom Water column, connection andthen to disconnect all of; the various connections so 'as to remove the Water, column `before .even

the inspectionV can Abe made. Sometimes after all; of this has been done,A it is found by thei'nspection that cleaning is not yet necessary. By the use of` the inspectionplug shown itis not necessary to remove the'water column.V The boiler may be drained to a pointv belenT thec level' of? the inspection plug and'ithen Without thefnecessity lofbreaking any of the connections thel inspectionjpl'ug is ,screvvedout and-removed. Hsed-imentA has fgormedtwithin thevvater column or it'i any solid matter has separated; out andr adhered to 'thecolumin itA will also adhere tofthe 1 fil inspection plug. Thus when the ins ection plug has been removed, there will ad iere to it some of the material adhering to"or remaining Within thewater column, and this will show the depth or thickness and quality of the sediment. rlhus by an inspection of the sample adheriner and lodging within the pockets of' the inspection plug', it is possible at onceto tell the condition ol the interior of the Water column. There further inspection is desired, an inspectingor testing tool or rod may be inserted through the hole from which the plug was removed and the necessar?v further inspection can be carried out. It 1s possible also to clean the `Water column throughthe opening. i n

The shape of the portion of the plugwhich extends into the water space within `the member B is such that at all times one oit the cavities or depressions in this part of the plug faces upward. Thus Whatever settlement takes place `from the Water or other fluid passing through will` tind ready lon ging lace in oneor more of the depressions of tlie plug, and thus no matter what the quality oi" the liquid, and no matter what the quality` of the material which settles `out Afrom it, it Will always find a. settlinguplace on the plug Where it may be received and retained. o i
