Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed February 16, 1916. Serial No. 78,663.

To all whom it may concern.

Be it known that 1, JOHN MOE. BOWMAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Heat-Radiating Unit, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention hasin view are; to prevent the freezing of the water employed as the heating medium in hot-water radiators; to provide means for maintaining continuously a circulation of the heating medium in the vicinity of the radiator for maintaining the temperature of the air surrounding the radiator above the freezing point; and to continuously maintain a limited circulation of the heating medium in the supply and delivery radials immediately connected with the radiators of the heating system.

Drawinga-Figure 1 is a side elevation of a radiator constructed and arranged in accordance with the present invention; Fig. 2 is a top plan view of the same; Fig. 3 is a detail view on an enlarged scale, showing in section a choking connection for the circulation bypass with which radiators constructed in accordance with the present invention are provided.

Descm'ptz'0n.ln domestic heating installations employing hot water as the heating medium, an inconvenience is experienced as the result of carelessness on the part of attendants or other persons using the system, and as the direct result of turning off the supply valve in order to reduce the heat of the room in which the radiator is installed.

Radiators are generally placed adjacent to window openings. When, as often happens, in addition to suspending the supply of heat, the occupant of a room raises the window to more rapidly reduce the temperature of the room and thereafter neglects to lower the window or to turn on the supply of heating medium before leaving the room, the water in the radiator freezes. The freezing of the water in the radiator operates to burst the columns or to expand the connections so that when subsequently the medium in the radiator is thawed, a flooding condition immediately results.

T o obviate the above stated difliculty, the present invention provides an auxiliary circulating pipe 8. The pipe 8 is preferably disposed at the rear of the columns of the radiator .9, intermediate and in the plane with the supply radial 10 and the delivery radial 11. The relatively long radials 10 and 11 are conventional. These radials are connected with the riser 12 and the downpipe 13, respectively, and to the ends of the radiator 9 farthest removed from the said riser and downpipe, as shown in the drawings.

The auxiliary circulating pipe 8 operatively connects the radials 10 and 11, being connected therewith by the pipe T-couplmgs 14 and 15, which couplings are disposed between the said radials and the inlet and

outlet valves

16 and 17, respectively. Consequent upon this arrangement, the heating medium continuously flows from the radial 10 to the radial 11, by way of the pipe 8, irrespective of the condition of the

valves

16 and 17.

To limit the flow of the heating medium through the pipe 8, a choke nipple 18 is interposed between the T-coupling 1d and the short riser 19 connecting the pipe 8 and the T-coupling 14, as shown best in Fig. 3 of the drawings, the nipple 18 has a contracted passage 20, which permits a limited supply of medium to pass to the pipe 8. The delivery end of the pipe 8 is free.

It is obvious that when thus constructed, trapping of the medium in the radial 10 is prevented, for though the valve 16 may be closed, the medium continues to flow through the nipple 18 to the short riser 19 and auxiliary pipe 8 and radial 11, and thence to the down pipe 13. The circulation thus maintained is suflicient to continuously furnish a limited supply of heat, which While not sufficient to incommode the occupant of the room, prevents the freezing of the medium in either the radial 10 or the radiator 9, when subject to the conditions above outlined as usually producing these objectionable results.

Claims:

1. The combination of a radiator; a supply pipe; a delivery pipe; a supply radial operatively connecting said supply pipe and said radiator, said'supply radial being disposed in parallel juxtaposed relation to said radiator, and extending lengthwise of said radiator for connection at the far end thereof; means controlling the supply of medium to said radiator, said means embodying a manually operative valve intermediate said supply radial and said radiator; and an auxiliary circulating member permanently connecting said supply radial and said delivery pipe, said member being disposed in parallel juxtaposed relation to said radiator and equidistant from said radial and delivery pipe, the connection of said auxiliary circulating member with said supply radial being intermediate said supply pipe and said valve.

2. The combination of a radiator; a supply pipe; a delivery pipe; a supply radial operatively connecting said supply pipe and said radiator, said supply radial being disposed in parallel juxtaposed relation to said radiator, and extending lengthwise of said radiator for connection at the far end thereof; means controlling the supply of medium to said radiator, said means embodying a manually operative valve intermediate said supply radial and said radiator; an

auxiliary circulating member operatively connecting said supply radial and said delivery pipe, said member being disposed in parallel juxtaposed relation to said radiator and equidistant from said radial and delivery pipe, the connection of said auxiliary circulating member with said supply pipe being intermediate said supply pipe and JOHN MOENTEE BOWMAN.
