BENJAMIN R. HAWLEY, OF CHICAGO, ILLINOIS, ASS IGNOR TO AGNES HAWLEY, OF SAME PLACE.

SYSTEM FOR HEATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 247,639, dated September 2'7, 1881.

Application filed January 21, 1881.

To all whom it may concern:

Be it known that I, BENJAMIN R. HAWLEY, of Chicago, in the county of Cook and State of lllinois,have invented certain new and useful Improvements in Systems for Heating Buildings, of which the following; is a specification.

This invention relates to a method of warming dwellings and other buildings independently of the ventilation, and is designed to obtain in a cheaper and better way the advantages attending the endless-pipe systems.

In mynewly-devised plan of warming I employ air as a circulating or heating fluid. I give the air a continuous and rapid movement in an endless path through a heater, suitable conducting-pipes, and'sheet-metal radiators.

In order to the more full' understanding of myinvention, Irefer to Figure 1 of the accompanying drawings, which shows a diagram of a building having my improved air-pipe system,and wherein 0. represents the heating fornace or stove, B B the pipes conducting the warm air from the heater to the floors above, and O O the pipes for returning the cooled air to the heater. Said heater is shown as having a surrounding air-space, a, within which the air is heated as it passes through the heater in its circuit of travel. A suitable outlet, A, is provided for the smoke, as shown. The warmair pipes lead from this air-space to apartments above, as shown, where they open into radiators D and D,respeetively. These radiators are of sheet metal,and preferably black metal, becausethereby the greatest amount of radiation is obtained. The pipes 00 take the air from the bottom of the radiators and return it to the air-space a in the heater, as clearly shown. They may be united or they may debouch separately into said air-space.

The conducting-pipes are made of non-conducting material or are surrounded by non- (No model.)

conductingmaterial or spaces; and one method of construction is illustrated at Fig. 2, the pipes passing through one of the joistspaces under a floor is shown as embedded in plaster or some similar material. The same plan may be followedwith upright pipes in partitions and similar places. I

Valves D are inserted in the pipes O U and B B, to shut off or regulate the flow of the hot and cold air.

I am aware that air has been used as a circulating heat-conveying fluid in an endlesspipe apparatus embracing a heater and rudiating-surt'ace; but my apparatus is very much more efficient than said prior apparatus, permitting, as it does, not only the obtaining of all the heat from the heat-conveying body, but also the raising ot'the temperature in the apartment warmed by the apparatus to a high degree. It is also more economical in the amount of room required by the conducting-pipes and the radiators, and much cheaper to make and put in place.

I. claim- 1. The combination of the healer, having the surrounding. air-space, the sheet-metal radiators, and the pipes adapted to conduct the air from the heater to the radiator and back from the radiator to the heater, a body of aircirculating through said air-space, radiators, and pipes, substantially as described.

2. The endless apparatus for heating by air, consisting of the heater, the metal radiator, and the conducting-pipes, made of or incased in non-conductin g material, and adapted to conduct the warm air from the heater to the radiator, and the cooled air from radiator to the heater, substantially as specified.
