4 Claims. (01. 257159) Our invention relates to new and useful ima nipple or bushing member 11, preferably of cast provements in radiators, and more particularly iron, which extends substantially across the to an inlet nipple or bushing embodied in the ra width of the first or inlet column or section. The diator. member 11 is preferably in the form of a hollow In the heating of radiators by steam, it' freplug having a substantially cylindrical body p01'- 60 quently occurs that the water of condensation tion 12 and a substantially cylindrical internal which collects at the bottom of the radiator will chamber or bore 13, which is closed at its inner cause water hammer when steam is admitted end by a wall 14 normal to the axis of the bore, to the cold or cool radiator, and the water hamand which at its other or outer end has an interv mer is more pronounced and certain of occurring nally threaded inlet port 15 to receive a steam G5 in a radiator having the steam inlet at an upsupply pipe or conduit member. The portion 12 per end nipple opening and a trap controlled outis externally screw threaded, as at 16, for a part let at the opposite lower end. It is also common of its length adjacent its outer end for threaded for the radiator heated by steam to trap air, i. e., engagement with internal threads in aperture 6.

At the bottom of the radiator in the end arrows M, with a small portion of the steam supn I walls thereof, there are apertures 8, 9 alined with plysplitting off and flowing down the intermediate the bottom nipple bores 3, the aperture 9 which sections, as indicated by the arrows S.

member 11, in accordance with our invention; the volume of steam directed internally across the top of the radiator is greatly reduced by. the aperture 19 and the greater portion of the steam admitted to the plug member passes through apertures 18 radially into the inlet section or column. As a result, most of the steam admitted to the bushing passes downward in the first or inlet column and then horizontally throughthe as the steam passes through each of the bottom openings, a quantity of the steam will split off andrise in each column, as indicated by the arrows y, it being apparent that the upflowing lquantities will taper off from the inlet column toward the outlet column. It will thus be seen that the air pocket under line AA is eliminated, the steam which rises in the respective intermediate columns carrying the air upward :before it into the path of the jet M, which serves ftoIsweep the air into and down the end outlet column, so that the air in the radiator is driven ,outiahead of the steam and before the steam reaches the trap 21. Elimination of water hammer, is also accomplished, because, as will be seen, the greater part of the admitted steam is moving through the bottom nipple openings 3 toward the outlet 8, and therefore acts to drive thewater ahead and into line 22 through the ;;open trap. Due to the elimination of the con- -densate and the air, the radiator will heat uniw-formly' throughout its area, so that the bushing member 11 causes an equalization in the heating gup'of the columns. p

-What We claim and desire tosecure by Letters :Patent of the United States is:- ;i.1.In a steam heating radiator; comprising a plurality of columns having alined top and bot- .tom openings for intercommunication between said columns, andin' which one of the end columns zhas a steam inletopening in line with said top openings, a substantially cylindrical member sealed in said inlet opening and extending into the radiator, said member having a substantially cy- =lindrical bore, said bore being open at its outer send and threaded to receive a steam supply'oonduit, and a wall member closing the inner end of .,-'said bore and having an aperture therethrough P substantially coaxial with said top openings, said 0 cylindrical member having anaperture through When the radiator is provided with a bushing steam flow openings adjacent their tops and botbottom openings 3, as indicated'bythe arrows ing in line with said top flow openings, a hollow by an alined top and bottom opening and in which substantially-coaxial with said top openings, and

the side wall thereof substantially in the vertical longitudinal center line of said one end column, whereby steam issuing from said second-named aperture will pass downward in said end column and thence upward in the intermediate columns to heat the radiator uniformly.

2.
