, RADIATOR ALVE.

Application-filed June 16,1925. Serial No. 37,541.

This invention relates to certain improvements in radiator valves and has relation more particularly to a valve of this type especially designed and adapted for use in connection witha hot water heating system or the like as disclosed in my pending" application Serial No. 27,098 filed April 192.3, and it is an object of the invention to provide a valve of this type with means to permit the required 'slight circulation through the radiator to prevent freezing dur ing'the periodthe valve i's Closed to temporarily cut out the radiator together with a supplemental valve operable to said means non-effective.

a Theinventio'n consists in the details of construction and in'the combination and arrangement of the several partsof my 'improved radlator valve whereby certain im' portant advantages are attained and the device rendered simpler, l ess'expen'sive and otherwise more convenient and advantageous for use. as will be hereinafter more fully set forth. v a

The novel features of my invention 'will hereinafter be definitely claimed. 7

In order that my invention may be the better understood, I will now proceed tov describe the same with reference to the ac companying drawings, wherein! Figure 1 is a diagrammatic view illustrating a heating system embodying the use of radiator valves constructed in accordance with an embodiment of my invention;

Figure 2 is a view partly in section and partly in elevation illustrating a valve constructed in accordance with an embodiment of my invention.

As disclosed in the accompanying draw-' ings, R denotes a plurality of radiators positioned as desired, each of which being in communication with a feed pipe 1 through the medium of a branch pipe 2 or the like.

Each of the radiators R is also in communication through a branch 3 or the like with a return pipe t. "The pipes 1 and't are each in requisite communication with'theheating unit H. It is to be understood that my improved system may be employedin connection with hot water, steam and the like. I

Each of the branches or lines 2 and 8 in communication with a radiator R has interposed therein'a valve mechanism M. This mechanism comprises a casing 5 having angularly related branches 6 to provide for render the'requisite coupling of the casing within the line. Threaded in a conventional manner through the "bonnet 7 secured tothe casing 5 is a stem 'Sthe inner or inserted end portion of which carrying the valve 9 for engagement with the internal valve seat 10.

As particularly illustrated in Figure 2, it is to be noted that when. the valve 9 is in its-full raised position, as indicated by dotted lines, it issentirely above the branchfi of the casing which is directly-in communication with a radiator R and'thatthe valve seat 10 is entirely below such branch. The wall, of the other or dependingbranch6 has dis posed 'therethrough an opening 11 and in communication with said opening 11 is'a port 12 also in communication with the internal or valve chamber 14 of the casing 5 at a point to one-side of the valve 9 and ofits seat '10, vsaid port also communicating with the chamber 14 below the valve?) when in its full closed position. Flow through the opening 11 and port 12 into the chamber-14- is controlled by the needle valve "15 having its outer portion provided with. an enlarge -ment 16 in threaded engagement withthe enlarged outer portion of the opening 11, said outer portion of the opening 11 being continued through the outstanding nipple 17 integrally formed with the casing 5. v nipple '17 entirely housesthe outer portion of the needle valve 15 when in its closed position and if desired, the outer open end of the nipple 17 may be closed by a conventional cap 18. The outer end portion of the valve 15, as herein disclosed,' is provided with an extension 19 angular in cross section whereby a conventional T maybe engaged with the needle valve 15 to adjust the same into either'open or closed position.

Each of the return pipes 4: ata point below thelowermost radiator R and preferably within the cellar of a building, has interof, a three-way type and preferably con- This structed in a manner particularly described in my pending application Serial No. 27,- 093 'hereinbefore referred to. Norma-11y" these'valve mechanisms Dare in a position to permit free flow through the pipes 43butwhen it is desired to cut out a radiator the inlet valve mechanism M-for such radiator is closed together with all of the other valve mechanisms of the other radiators in communication with the same return pipe. The drain valve 1) interposed in such return pipe.

is then moved to a position to permit the water in such radiator to readily drain out, after which the valve 15 in each of the valve mechanisms M in communication with said radiator R is closed as is also the main valve in the outlet mechanism and the valve D is returned to its normal open position. By this means, the single radiator is completely cut out without in any way interfering with the functioning of the remaining radiators ot' the system, it being understood that after a radiator has been drained the valve mechanisms M of the other radiators are opened. I

From the'particular structure of the radiator valve as illustrated in Figure '2 of the drawings, it is to he noted that when the valve 9 is in its full closed position and the needle valve 15 is in open position, the clesired antifreezing circulation through the casing readily passes a closed valve M and without any other undue hindrance or ohstruction thereto, and it will also be noted that when the valve 9 is in full open position, as indicated by dottedlines, in Figure 2, full flow of the fluid is had throughthe casing 5 without undue hindrance or retardation being oiiered by such valve.

From the foregoing description it is thought to be obvious that a radiator valve constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled'and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim In combination With the radiator of a hot water heating system, a valve mechanism comprising a casing having; angularly related branches, one of said branches being in communication with the radiator, a water line in communication with the second branch, said casing being provided with an internal valve seat, a valve within the casing, means for moving the valve toward or from the seat, a wall of the casing being provided with a restricted port leading from the valve chamber of the casing to a point within the casing outwardly of the valve seat, said port when opened and the valve closed permitting a slow retarded flow through the radiator, and a supplemental valve operable in dependently of the first named valve and ac.- cessihle exteriorly of the casing and without removing the casing for closing at will the flow through the restricted port, said first named valve and supplemental valve when seated effectively closing flow through the first branch permitting removal of the radiator without draining the system in which the radiator is comprised.

In testimony whereof I hereunto my signature.
