HEATING SYSTEM.

Application filed n rlieo, 1925. Serial No. 27,093.

This invention relates to certain improvements in heatlng systems embodying the use of hot water or the like and it is an object of the invention to provide a system of this kind wherein a radiator may be readily removed without in any Way affecting the operation and efficiency of the remainder of the system. H

It is also an Object of the invention to provide a system of this character wherein each of the radiators comprised therein may be separately or independently cut out and drained and to permit the removing of such radiator if desired Without affecting the re mainder of the system.

An additional object of the invention is to provide a system of this kind wherein parts thereof may be readily cutout as desired, the

system permitting such non-working portions to be readily drained so that the liabllity of breakage due to freezing is eliminated.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved heating system whereby certain 1mportant advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. r

The novelfeatures of my invention will hereinafter he definitely claimed.

In order that my invention maybe the better understood, 1 will now proceed'to describe the same with reference to the accompanying drawings, wherein Figure l is a diagrammatic view partly in elevation and partly in section illustrating a heating system constructed to show an embodiment of my invention;

Figure 2 is a sectional view taken through one of the valves associated with a radiator;

Figure 3 is a view similar to Figure 2 showing the valve in closed position;

Figure 4 is a sectional view taken through the drain valve as herein employed.

As disclosed in the accompanying drawings, R denotes a plurality of radiators positioned as desired, each of which is 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 4:. The pipes 1 and 4 are connected to heating unit H. It is to be understood that my improved system may be employed in; connection with; hot water, steam and-the like. v 7

Each of the branches or lines 2 and 3 in communication with a radiator-R has interposed therein a valve mechanism VI, This mechanism comprises a casing 5 having angularly related branches'6 to provide for coupling the casing in the line. Rotatably mounted within the casing 5 is a rotary valve '7 of a hollow type with its opposite ends closed. The side or peripheral wall of the valve member 7 is provided with the ports 16 spaced apart a distance so that when the member 7 is in one position, unobstructed flow through a branch 2-or 3 is assured and when turned into a second position as in Figure 2,. flow of the heating medium through the radiator is substantially stopped. When in this position the branches 6 of' the casing 5 have in communication therewith the restrictedopenings 18 to permit a slight circulation through the radiator to prevent freezing. When the valve member 7 is moved into a third position as illus- "trated in FigureB, flow through a'branch 2 or 3 is prevented.

A branch 6 of the casing 5 comprised in the mechanism M interposed in a return branch 3 has associated therewith an air valve 19 to provide means whereby'it may be readily determined whether or not the heating fluid within a radiator R has been completely drained therefrom and which is of especial import when it is desired, for any cause, to remove such radiator.

Each of the return pipes 4: at a point below the lowermost radiator R, and preferably within the cellar of a building, has interposed therein a drain valve mechanism 1). This mechanism comprisesa casing 20 provided with the opposed ports 21 adapted to besuitably coupled Within a line 4 and with a third or intermediate port 22 which is normally closed by a cap 28 or the like. A valve member 24 is rotatably arranged within the casing'20 and is provided there-- through with-a port 25 and with the intermediate port 26. Normally, the port 25 is in communication with the ports 21 and the branch port 26 is closed whereby unobstructed flow is permitted through the return pipe 4. l/Vhen it is desired to cut out a radiator the inlet valve mechanism for such radiator is closed together with, all of the valves of the other radiators in communication with the same return pipe. The valve member 24:

is then turned to bring the port 26 into register with the port 22 so that with the cap 23 taken off, all of the water or other heating medium within the radiator R to be removed can be readily drained out without With a system constructed in accordance with my inventionas herein disclosed, it will be readily understood that one or more radiatorsmay'be readily removed if desired without requiring the entire system to be drained or interfering with theremainder ofthe system and it will also be obvious that in my system the various radiators R may be rendered inoperative from' a heating standpoint when such use is'not required and can be readily drained to pr'eventbreakage asthe result of freezing.

From the foregoing description it is thought to be obvious that a heating system constructed in'accordance with my in vention is particularly well adaptedfor use by reason of the convenience and facility with which it may'b'e'assembled and opmodification 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.

A fluid heating system comprising a heat generating unit, a plurality of heat radiating units, arsupply pipe leading from the heat generating unit, a return pipe leading to the heatgenerating unit, individual pipes connecting each of theradia-ting unitswith the supply pipe, individual pipes connecting'each of the radiatingunits-with the return pipe,"valves interposed-in the individual pipes for controlling the flow therethrough, and a three way valve interposed within the return pipe belowthe radiating units, said three way valve in oneposition allowing circulation through the heat generating unit and 'theradiating'units, and said three way valve when in a secondpositi'on'preventing flow through the return pipe ."CO the heat generating unit and permitting the portion of the return pipe above the three way valve to drain. 7

In testimony whereof Ihereunto aiiix my signature.
