UNITED STATES PATENT OFFICE.
GEORGE LINCOLN BRYANT, OF VICTOR, COLORADO.
AIR-HEATER.
To all whom it may concern:
Be it known that I, GEORGE L. BRYANT, a citizen of the United States, residing at Victor, in the county of Teller and State of Colorado, have invented a new and useful Air-Heater, of which the following is a specification.
This invention relates to air heaters of that type in which the air is heated by passing it through a tortuous pipe inclosed in a casing, and surrounded by a heating medium, such as steam or hot water.
The aim of the present invention is to provide a heater of this kind which is simple in construction and highly eflicient in action, and to this end it consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed in which Figure 1 is a plan view, and Fig. 2 is a central vertical section of my heater.
Referring more particularly to the drawing, there is shown a closed casing comprising a cylindrical shell 5, a top 6, and a bottom 7 This casing is supported on legs 8. Entering the bottom 7 of the casing, at the center thereof, is an inlet pipe 9 for the steam, hot water, or other heating medium, and connected to the top 6, at the center thereof, is an outlet pipe 10 therefor.
Mounted in the hereindescribed casing, is a series of concentrically coiled pipes 11, three of such pipes being shown. These pipes extend between the top and bottom of the casing, and open therethrough. The air enters the pipe at the bottom of the casing, and is discharged therefrom at the top. If desired, the pipes may be connected to pipes or conduits leading to the outside of the building, in order that a supply of pure air may be had.
In use, the steam or hot water, is let into the casing, whereby the air passing through the pipes 11 is rapidly heated, and it is discharged from the outlet end of said pipes at the top of the casing. By coiling the air pipes, a large area is exposed to the heating medium, and the air travels a long distance before it is discharged, so that when it leaves the heater, it will have nearly the same temperature as the heating medium, and at the same time the space occupied by the pipe is Specification of Letters Patent.

reduced, and the casing may therefore be made small so that the heater will take up but little room.
The heating medium employed will be preferably exhaust steam, thus adapting the heater more particularly for factories or other buildings equipped with a steam plant. The exhaust steam is therefore made to serve a useful purpose, and the heater is operated without extra expenditure for fuel.
The flow of air to the heater is regulated by means of valves 22 at the entrance of the air conducting pipes.
What is claimed is:
1. An air heater comprising a closed casing adapted to contain a heating medium, and having an inlet and an outlet for such medium, a series of concentrically coiled, and independent air-conducting pipes mounted in the casing, said pipes having independ ent inlet ends opening to the atmosphere at one end of the casing, and independent discharge ends opening to the atmosphere at the opposite end of the casing, and valves for each of said pipes at the inlet ends thereof, whereby the flow of air through each of said pipes is controlled.
2. An air heater comprising a closed casing adapted to contain a heating medium, and having an inlet for said medium at one end, and an outlet therefor at the opposite end, said inlet and outlet being in alinement, a series of concentrically coiled, and independent air-conducting pipes mounted in the casing, and also arranged concentrically with respect to the aforesaid inlet and outlet, said pipes having independent inlet ends opening to the atmosphere at that end of the casing through which the heating medium enters, and said pipes having independent discharge ends opening to the atmosphere at that end of the casing from which the heating medium is discharged, and valves for each of said pipes at the inlet ends thereof, whereby the flow of air through each of said pipes is controlled.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
