THADDEUS FAIRBANKS, OF ST. JOHNSBURY, VERMONT.

RADIATOR.

SPECIFICATION forming; part of Letters Patent No. 231,413, dated August 24, 1880.

Application filed January 6, 1880.

control of the fire and active circulation of the heat horizontally to distant portions of an extended building or to a separate building due to steam-heating. I combine a hot-water system of pipes or radiating apparatus with a steam-generatin g system at the furnace, using pipes and suitable provisions for connecting to carry the steam to the hot-water system, to impart the heat from the steam to the water, and to conduct away the resulting water of condensation.

The accompanying drawing forms a part of this specification, and is a side elevation of my apparatus, partly in section, with a section of a part of the. building in which it is used.

A is the floor, and A is one of the walls of a building or of an apartment thereof. 1 will designate thespace to be warmed, briefly, as a 64 r B is a steam-pipe, bringing steam at any convenient pressure from a distant boiler, M. It extends up to a considerable height, then horizontally a little, and thence downward into my hot-water-heating system. It is continued downward through the hot-water-heating apparatus by a larger pipe, (marked B,) which I will term a heating-vessel. Near the bottom it again contracts, and emerges at the base of the same size as it enters. It extends from the base back again to the boiler M.

The hot-water apparatus is composed of several parts suitably disposed to present the Water efficiently to the steam-pipe B and receive heat therefrom, and allow the water thence to circulate through the other bends and parts and give off its heat to the air of the room.

D is a continuous upright part of the hotwater apparatus, which I will term a heatingchamber, surrounding the steam-pipe B.

D is a horizontal part extending from the top of D. The water heated by the steampipe B rises in D, flows horizontally through D descends through D, flows along through D, descends through D flows horizontally through D", descends through D and finally flows horizontally through D and succeeding similar connections to the base of D, in which it again rises. Its circulation through D 850., gives heat to the air of the room and cools the water, but each rise through D again heats it.

The pipes D D D 850., are formed and arranged to allow an active circulation of the air of the room to the outer surfaces thereof.

The portionsD and D", being in line with each other, are made in one, with simply a tight partition across at the mid-height.

Modifications may be made in the details without departing from the principle or sacrificing the advantages of the invention. There may be more of the hot water apparatus. The returns may be nearer together or wider apart. They may extend up and down or inclined. I can use a coil in place of the large straight pipe B, in which the steam imparts its heat to the water.

I esteem it important to provide for a reasonable amount of expansion and contraction of the water relative to the containing vessels or pipes. For this I provide a globe, E, to contain air, which may, by its elasticity, be compressed or expanded within wide limits. Ordinary provisions (not shown) may be made for adding water and for draining the apparatus when desired.

I propose to use the device for warming all kinds of buildings and apartments. I esteem it especially adapted for green-houses. The temperature may be controlled by a cock on the steam-pipe B, (not shown,) or by a cook or other device 'for checking the circulation, (indicated by a circle at G in the figure.) The partial closing of such cock, and thus retarding the flow of the water, allows the water in the immediate vicinity of the steam-pipe B to become heated up to the temperature of the steam without much raising the temperature of the other parts of the radiator, while a slight increase in the opening will allow a slow circulationand allow the effect to he graduated chamber, 1), with the contained heating-veswith great nieet v. sel B and steam-supply B, as and for the I am aware that steam led through pipes purposes herein set forth. plain and variously coiled and convoluted has In testimony whereof I have hereunto set 5 been employed to heat water and other fluids, my hand this 22d day of December, 1879, in t5 eminently sugar-liquor.
