ATTACHMENT FOR HOT-WATER RADIATORS.

Specification of Letters Patent.

Patented Mar. 31, 1914.

T 0 all whom it may concern Be it known that 1, CHARLES E. BRINEY, of Coraopolis, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Attachments for Hot-Water Radiators, of which improvement the following is a specification.

My invention relates to means for effecting the controllable supply and discharge of hot water to and from the radiators of hot water heating systems, and its object is to provide simple and inexpensive means whereby the flow and return of hot water may be regulated as desired and which will also perform the function of a by pass for conveying the flow to another point of delivery when shut off from the radiator.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a side view, in elevation, of a hot water radiator, with my improvement, shown in section, applied; Fig. 2, an end view of the same; Fig. 3, a vertical section, on an enlarged scale, through the flow and return fitting, on the line a a of Fig. 4; and Fig. 4, a similar section, on the line b b of Fig. 3.

In the practice of my invention, which is herein shown as applied in connection with a hot water radiator, 1, comprising a plurality of assembled sections of the ordinary construction, I provide a flow and return by-pass fitting having a body, 2, lower and upper end nozzles, 2 and 2, a lateral nozzle, 2, and a lateral nozzle, 2 at substantially a right angle to the nozzle, 2, said lateral nozzles being interposed between the end nozzles. An upwardly curved deflector, 2, extends from the bottom of the opening through the nozzle, 2, to or near the vertical central plane of tho fitting.

A vertical'supply flow pipe, 3, is connected to an elbow, 3 which is in turn, connected by a union coupling, 3 to the nozzle, 2, of the body, 2, of the fitting, and a return or discharge pipe, 4, is connected to the nozzle, 2*, thereof. A spud or short section of pipe, 5, is connected, by a union coupling, 5*, to the nozzle, 2, and its opposite end 1s screwed into an opening in the adjacent section of the radiator, 1, near its bottom. A vertical radiator supply pipe, 6, leads from theupper nozzle, 2", to the casing, 7, of a regulating valve, 7 which controls communication between the pipe, 6, and the upper portion of the adjacent section of the radiator, through a short connecting pipe, 8.

The fitting is, so far as described, operatively complete, but'in order to obviate the necessity of making right and left hand patterns for it, a nozzle, 2, is preferably, as shown, formed on the body, 2, opposite the nozzle, 2 and similar thereto, the additional or reserve nozzle, 2, being closed, when the fitting is connected to the radiator, by a cap, '5".

In operation, hot water supplied to the body, 2, of the fitting, through the pipe, 3, passes through said body and the pipe, 6, past the regulating valve, 7, into the upper portion of the radiator, replacing cooler water which passes from the lower portion of the radiator into the body of the fitting, through the spud, 5, and passes from the fitting through the return.pipe, 4, the flow of the hotter water being separated from that of the cooler Water by the deflector, 2.

When the regulating valve, 7, is closed, the.

flow of hot water to the radiator ceases, and the fitting then acts as a by-pass, the hot water supplied thereto through the supply flow pipe, 3, passing over the top of the de- Hector, and thence to the return ipe, 4, through which it may be conducte to any desired point of delivery. The lower pipe connection of the radiator, through which full drainage may be effected, is always open to single pipe circulation, and a sufiiciently high temperature is maintained to prevent the radiator from freezing.

It will be seen that by my improvement the connections to the radiator are simplified, and are both made at the same end, and that no separate by pass appliance is required. The appliance is of simple construction and of slight cost, and is readily adaptable in connection with hot water radiators of the ordinary standard forms.

I claim as my invention and desire to secure by Letters Patent:

1. The combination, with a hot water radiator, of a fitting formed with a passageway extending therethrough, and having end nozzles and intermediate nozzles communicating with said passageway; pipes providing connection between one of the end nozzles and the upper port-ion of the radia-' tor, and between the lower portion of the radiator and one of the intermediate nozzles, respectively; supply and return plpes communicating with the other intermediate nozzle and with the other end nozzle, respectively; and a deflector in the fitting, separating the intermediate nozzles and formed to direct the heated water toward the radiator supply nozzle.

2. The combination, with a hot water radiator, of a fitting formed with a passage- Way extending therethrough, and having end nozzles and intermediate nozzles communicating with said passageway, the level of the lower end nozzle being such as to provide for radiator drainage; a pipe connecting one of the end nozzles and the up er portion of the radiator; a regulating va ve controlling the supply of water through said pipe; a pipe connecting one of the intermediate nozzles and the lower portion of the radiator; supply and return pipes communicating with the other intermediate nozzle and with the other end nozzle, respectively; and a deflector in the fitting, separating the intermediate nozzles and formed to direct the heated water toward the radiator supply nozzle.

3. A flow and return and by-pass fitting for hot Water radiators, having a passage- Way extending therethrough; lower and upper' end nozzles communicating with said passageway, for the connection of a return water pipe and a radiator supply pipe, respectively; an intermediate lateral nozzle for the connection of a supply flow pipe; another intermediate lateral nozzle located at an angle thereto, for the connection of a radiator discharge pipe, each of said intermediate nozzles communicating with said passageway; and a deflector separating the intermediate nozzles and formed to direct the heated water from the supply flow pipe nozzle toward the radiator supply pi e nozzle and to separate the flow of the coo er water from the radiator discharge pipe nozzle from that of the hotter water from the-supply flow pipe nozzle.
