or CHICAGO, ILLINOIS 1 provide means for trapping and holdingin float onthe surface of the water of condensation which collects in the bottom of the radiator. v c. 101 ,The ordinary steam radiator is made up of cast iron sections. The cores used for castingthe sections contain grease and some of this grease adheres to the inner surfaces of the radiator from which it is likely to be 1.53 dislodgedlittle by littleyafter the radiator has been installed; This grease, with other foreign matters 1 such "as dirt, traces of coarse, sand and thelike, collects as v a scum on the surface of the water of condensation 2Q: that accumulates in the radiator and escaping through the outlet pipe, in the case ofa two-pipe system such as the ordinary vapor system, orthrough the commoninlet and outlet pipe of a one -pipe system, causes 1' 5. trouble and inconvenience by clogging valves and traps andparticularly by forming a grease film in theboiler to which, in most cases, water of condensation is returned,th e grease film interferingwith the 3Q, vaporization of. the water in the boiler. Even. when the water in the boileris drawn 01f for the. purpose of clearing the boiler of this grease film, which invariably "ac cumul'ates during thefirst few days opera- 3Q", tion ofgthe heating system, the remedy is only partial. Theggrease collectson the walls 'ofthe boilersandwhen fresh water is introduced forms a new film on this body ofwatenfvv v 14! My invention contemplates providing a simple landf inexpensive means of holding the grease scum in theradiator. So far as itescap'es at all it is in very small quantities so that the harm done isminimized.
A furtherobjectbfZ the invention is to provide a device of this character which can be used with the radiator of a one-pipe steam heating system; or interchangeably with the radiator of a two-pipe system. In
' is e a he de i e i a m r v m My invention is concerned with certain improvements in steam heating systems. 1 ()ne of the objects of the invention ls to tor by a' short pipe section 14: and gland 15,

upon that patentedin my Patent No. 1,592,- 92.7 granted July 20, 1926, which device can be used only with a two-pipe system, that'is at the outlet end .ofthe radiator. I The same device. serves a different and important function when used in the radiator of a one-pipe system. -It'acts' as .a deflector... of the incoming steam causing the steam to 1 rise through the end section of the radia tor so that water hammer is prevented. Be cause of this, smaller pipingmay be used.1 This prevention of water hammer and use constitutes another object of smaller piping of the invention. v
The invention is illustrated in a preferred 65- embodiment in the accompanying drawings in which: i Y f Fig. '1 is a fragmentary side elevation of the steamradiatorof a one-pipesteam' sys-.v tem, embodying the grease reta'iningdevice of my invention. v Fig. 2 is a similarfview of the radiator of a vacuum steam system showing thegrease. retaining device as applied at the outlet end. of the radiator. V l I 75 Fig. .3 is a sectional perspective view of the. nipple, modified 'in accordance with my. invention, for fastening together the lower ends of the adjacent end sections ofthe radiator,- and I Fig. 4 is aviewiinperspective of the grease retaining device. a I
' .Referring'first to Fig.1, 10 designates a radiator for acne pipe steam heating sys temconsisting ofa plurality of cast iron sections secured together, in the usual way, at the top and bottom ofthe sections. 11 des ignates the common supply and return pipe through which steam passes to the radiator and which receives water of condensation outflowing from. the radiator, this pipe being provided ordinarily withra shutolf valve'12 connectedito the end section 13 of the radiawhich latter screws into an opening formed 5 in a boss 16 on the end radiator section 13. The sections of the radiator except theend section13 and the vadjacent section 17 are secured together at. the bottom with the usual externally-threaded sleeves or nipples with a rabbet 21. This rabbet is provided so as to form a suitable seat for the grease retainer and steam deflector 22 shown in" enlargedperspective in Fig. 4. This device is preferably cup-shaped, consisting of a cylindrical side wall 23 and an end wall24. Afterthe'radiator has been built up, section by section, the device 22 isput through the opening which afterward: receives gland '15, and is fitted tightly into'the rabbet 21 of the'specially formed nipple 20 which secures together the two adjacent end sections 13 and1'7. The device 22, which isarranged toproj ect into and engage frictionally' within'the interior ofthe end section, is formed with .an aperture 25 of considerable size and-is arranged sothatthis aperture will be at the bottom. In order to "adaptthe device iasfgrease retainer for use interchangeably in a two-pipe system,'as will be described, the end Wall of the cup. may be formed with a smallvent 26 as shown in Fig.2. "This openingperforms no function when the device is used in-the radiator of a onepipe systemand is omitted preferably because of possible interference with the steam'deflecting function of the device. In a one-pipe system, itwill be understood the air ordinarily escapes .from the last section, designate d27 on the-drawing) through an air valve28. Thevent in any case is'located high enough. so that it will be above the'normal level 'of'the water in the radiator which is indicated by dotted line 60-41 Fig. 1. The
applicationbf thedevice'to a radiator of a twopipe vacuum system "is illustrated in Fig.2. -29 designates the supply pipe, shown as provided with .the usual shut-off valve 30. This'pipe delivers steam'tothe upper portion of "one of the end'sections 31 ofthe radiator. "32 is the return pipe provided with a steam trap-33. The 'device22'which functions solely as a grease retainer,'is arranged in the passageway between the end radiator section 3%1'andthe adjacent section 35, being fitted into the nipple 20 in the samewaysas in the case of the radiator showniin Fig. 1. The vent 26 permits the outflow from the radiator of air and of enough'steam to actuate the trap 33.
Inbothlthearrangements shown in Figs. 1*a'nd2 the orifices'25'are below the water level inthera'diator which is fixed 'bythe loweredgeofthe connecting pipe 14 (Fig.
1) or 36 (Fig. 2). Therefore any floating scum which collects in the radiator is retained therein, except for the small amount which comes from the walls of the end radiator sections 13 and 34. The orifice 25 is large enough to permit free outflow of water of condensation in'the case of a two- 'pipe'system and also inflow of steam as well as'outflow of condensatein the case of 4a one;pipe system. The vent 26 is above the normal water level in the radiator. It can bejmade quite small since its only functior is to permit the outflow of air from the radiator and of enou'gh steam to actuate the trap, thatis in the case of a two-pipe system. It has no function in a radiator ofav one-pipe system.
In a one-pipe system pels the steam entering the end radiator section '13 to rise inithat section whence "it is distributed'to the other sections through the duct or passageway'37at the upper entl of the radiator instead of -moving horizontally into and through the bottom duct or passageway connecting 'the ratliator sections. This prevents water hammer likely to occur'in'the' radiators o'f-a one pipe'system due to the "meeting of the :incoming steamand the outflowingwater offcondensation. To check this .it has "been customary to reduce the'velocityo'f the'steam by-using pipingof relatively large diameter. When the steam deflecting device :of my invention is employed, it is possible to reduce the diameter of this'piping besides eliminating the possibilityof water hammer;
Realizing that modfiications might "be made, *I'wish it to be understood that Iintend to cover by patent all such modifications within the scope of the appended claims.
By the term heating medium as usedin the claims I intend to :include both steam and water'of condensation.
