UNITED 'TATES PATENT OFFICE.

AUGUSTUS C BARLER, OF FREMONT, NEBRASKA.

HOT-AIR FURNACE.

SPECIFICATION forming part of Letters Patent No. 463,209, dated November 1'7, 1891.

Application filed February 20, 1890. $e1'ial No. 341,114. (No model.)

T0 on whom it may concern:

Be it known that I, AUGUSTUS C. BARLER, a citizen of the United States of America, and a resident of Fremont, in the county of Dodge and State of Nebraska, have invented a new and useful Attachment for Hot-Air Furnaces, of which the following is a specification.

My object is to combine an auxiliary radiator and a draft-regulator with a furnace, air-conducting tubes, and and an escape-flue in such a manner that the interior of the radiator will be accessible through the draftregulator, as required, to facilitate cleaning the radiator without detaching or separating any part of the complete device, so that it will be a permanent furnace attachment and fixture in a building adapted to economize fuel and labor in operating a furnace to heat a building.

My invention consists in the construction and combination of an auxiliary radiator and a draftregulator with a furnace, an escape fiue, and air-conveying tubes in a building,

as hereinafter set forth, pointed out in my claim,and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section, and Fig. 2 a transverse section, of the radiator. Fig. 3 shows my complete invention applied to a furnace in a building as required for practical operation.

A is adrum of common form, that has openended tubes fixed in its top and bottom.

B is an open-ended jacket in concentric position with the drum.

C is a tube fixed to the lower end of the jacket to convey cold air. 7

D is a corresponding tube fixed to the top of the jacket to convey heated air to a room in a building.

1 is apipe fixed in coinciding openings in the upper portion of the drum A and the jacket B to convey products of combustion from a furnace into the drum.

2 is a pipe fixed in coinciding openings in the lower portion of the drum and jacket to convey smoke and waste products of combustion from the drum.

I1 is a draft-regulator of common form on the end of the pipe 2.

By thus combining the drum, the jacket, and the draft-regulator, by means of single straight piece of open-ended pipe, soot or ashes that accumulate in the drum can be readily removed through the open-ended pipe that communicates with the drum.

3 is a pipe fixed to the pipe 2 to establish communication with a smoke-fine to carry off the waste products of combustion that enter the drum through the pipe 1, descend in the drum, pass'out through the pipe 2, and ascend through the pipe 3 to a smoke-flue L and a chimney.

The different parts may be made of cast metal in molds or of sheet metal, and joined together by seaming, riveting, or in any suitable Way to produce an attachment that is complete in itself and well adapted to be readily and advantageously applied to and operated with furnaces of different kinds for heating buildings.

In the practical operation of my invention when applied .to a furnace, as shown and described, the caloric that passes with the smoke into the drumis absorbed by the wall of the drum and-the open-ended tubes, so that the aggregate area of their inside surface will be a heating-surface and their outsides a radiating-surface from which the caloric will be imparted to cold air that is conveyed upward to envelop the drum, and also to pass into the tubes in the drum to become heated as it ascends inside of the jacket to the tube that conveys it upward into a room in a building.

The draft can be readily regulated in a common way by means of the draft-regulator and the damper.

I claim as my invention- In an attachment for furnaces, the combi nation of a drum having open-ended tubes fixed in its top and bottom and having an opening in its upper portion upon one side and another opening in its lower portion upon the opposite side, even with the bottom, an outer shell around the drum open at each end and having means for connecting it with pipes leading from the cold air to the interior of the room, and also having openings in its sides coinciding with the openings in the drum, a pipe extending through each set of openings, that at the top being adapted to engage with the furnace and the lower one being on a level with the bottom of the drum and having its outer end open and provided with a hinged door, and a vertical pipe communicating with the lower pipe between the 10 outer end and the outer casing and adapted to engage with apipe leading to the chimney,
