JOHN N. RICHARDSON, OF CINCINNATI, OHIO, ASSIGNOR TO THE WILLIAMSON HEATER COMPANY, OF CINCINNATI, GHIO, A CORPORATION OF OHIO.

HGUSEI-IOLD-FUENACE.

Application filed. October 15, 1915.

To all whom it may concern:

Be it known that 1, JOHN N. RICHARDSON, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Household-Furnaces, of which the following specification is a full disclosure.

My invention relates to an improvement in a house heating furnace.

One of the objects of the invention is to increase the cubic dimensions of the radiator, without adding to the height of the furnace structure, and hence to increase the heating efficiency by increasing the area of radiator surface in the hot-air jacket formed between the furnace proper and its casing.

Another object of the invention is to improve the radiator structure.

Another object of the invention is to provide a radiator structure adapted to receive and to coordinate with a radiator cleaner mechanism, of simple and durable construction and operation.

Another object of the invention is to establish a controllable communication between the radiator and ash-pit, which will usefully function for either cleaning the radiator, or when shaking ash into the ashit. p Another object of the invention is to provide an effective radiator cleaner, self-com tained within the radiator, and which can be used while the furnace is in full heat.

Another object of the invention is to so construct and coordinate this radiator, cleanout and ash-pit, that they can be conveniently installed with reference to the limitations and requirement of a particular basement lay-out, as, for instance, the relative furnace disposition depends upon the convenient place for putting in the fuel, and the furnace must be placed to register its smoke outlet with the chimney outlet in the basement.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a vertical transverse section through the furnace.

Fig. 2 is a perspective view of the radia tor sweeper,

Fig. 3 is a plan section on line 2-2, Fig. 1.

Specification of Letters Patent.

Patented July 8, 1919.,

Serial No. 55,921.

Fig. 1 is a vertical section of the radiator on line H, Fig. 3,

The ash-pit 1, fire-pot 2, combustion chamher 3, radiator 1 and casing 5 are conventionally arranged, though the ash-pit, radiator, and easing have unique structural formations designed to effect the stated objects of the invention,

The radiator, (see Fig. 3), has the central chamber 6, over the combustion chamber, the circumferential portion 7, which provides the radiating surface area in the hota1r jacket space 8, the radial passage-way 9 between chambers 6 and 7, and the radial reinforcing webs 10. The floor 11, of pas sageway 9, is raised above the horizontal plane of the top of the combustion chamher, and the chamber portion 6 has the depending annulus 12, fitting in the grooved ring 13, of the combustion chamber, enabling the radiator to be eircumferentially adjusted during installation, to properly position the outlet 14C, for escaping products of combustion from the radiator, with reference to the smoke-stack position in the basement.

The floor 15, of the radiator circumferential portion, is dropped below the floor 11, thus relatively enlarging the radiator dimensions without adding to the height of the furnace. This dropping of the floor 15, relative to floor 11, also provides a base recess chamber in the circumferential portion of the radiator, below the plane in which the products of combustion enter the said circumferential portion, in which the radiator clean-out mechanism can be perm anontly contained without being exposed to the extreme heat zone of the passageway 9. Within this radiator subrecess 16, and resting on floor 15, is placed the double-end sweeper 17, which is an I-beam shaped casting, having the eyes 18, at each end for attachment of the operating chains 19. There may he a single chain, or two chains, the inner ends of which are attached to the opposite heads of the sweeper, and the outer ends pass through the radiator opening 20, and lie in an inclosed compartment 21 in the hot-air jacket space, to which access is had through the exterior door 22. The floor 15 of the radiator, at this point of chain emergence, has the cut-out portion 23, from which pipe 24 extends downwardly to the ash-pit, communicating with an aslrpit opening 25. and this pipe has a damper control 26.

The floor of the radiator is formed with two or more such openings 23, the one not in use being covered over, or the floor metal may be thinly cored enabling one opening to be broken through for pipe 24, depending on the radiator adjustment. The radiator opening 23 not used is preferably closed by a cover 23*.

Preferably I form the ash-pit casting with a plurality of thinly cored sections 27, any one of which can be broken through to form an opening 25, for pipe 2st, depending on the particular circumferential adjustment of the radiator, or, the openings can be completely formed, and all but the selected opening capped over, the availability of the selection of one of several possible openings being the desideratum.

And I may provide the radiator with a plurality of ports for chain emergence and cleaning drop, those being selected during installation which approximately register with the particular ash-pit opening provision indicated by the particular radiator adjustment, and the other radiator openings can be closed by a plate or door, furnished for such purpose.

Preferably, also, I provide a door 28 for cleaning off the floor 11 of the radiator passage-way 9.

WVhen it is desired to clean the radiator, the door to compartment 21 is opened, and the attendant can take a wire hook for holding an outer end of the chain and draw the sweeper entirely around the floor of the radiator, pushing the deposit before it, and dumping it into pipe 2a, whence, the damper being open, it will drop into the ash-pit, and by then pulling the sweeper in the other direction, by manipulating the other chain end, the floor will be swept in the reverse direction.

Also, the damper can be opened when shaking the grate-bar, so that the impalpable dust and ash will be drawn into the radiator by the slight up draft, and so kept from flying into the face of the attendant and escaping into the basement.

Not only can the cellar be kept much cleaner by this means, but the full efiiciency of the radiator can be maintained by cleaning the radiator as often as deposit accumulates appreciably in the radiator. The cleaning mechanism is always accessible, being self-contained and can be easily manipulated, without the danger of the attendant being burned or soiled.

It is also a great advantage to have this selective provision, so that the pipe 2% can be connected up during installation to estab lish communication between the radiator and ash-pit at a point made necessary by the radiator adjustment.

By means of this clean-out provision, and. the extended radiator surface, the heating efficiency is materially increased and can be uniformly maintained.

I claim 1. In a hot air furnace comprising a furnace body having a combustion chamber and ash pit, an annular radiator on the combustion chamber through which the combustion products pass, a casing surrounding said body and radiator, the radiator being formed with an opening in the floor and an adjacent opening in the wall, the ash pit wall being also formed with an opening, a conduit between said body and easing leading from said radiator floor opening to the ash pit wall opening, a hollow member supported by the outer casing and extending inwardly into registration with said radiator wall opening and having an outer door forming a compartment between the body and casing adjacent the radiator, a sweeper on the floor of the radiator, and a chain device in the radiator attached to said sweeper and having an operating portion disposed in said inclosed chamber.

2. A hot-air furnace combining a fire box, an annular radiator arranged thereabove and connected by a flue to receive the prodacts of combustion therefrom, said radiator being provided with a door and also with a trap for the discharge of fine dust, a sweeper located in said radiator, a chain leading in opposite directions from said door to said sweeper whereby it may be caused to travel in either direction circumferentially within said radiator by manipulating said chain through said door, and means for making a conduit connector between the radiator floor-and ash-pit wall at a point determined by the conditions of installation.

3. A hot-air furnace combining an annular shell forming the wall of an ash pit and having in its circumference a number of dummy ports, a furnace body overlying said ash pit and providing a fire box and combustion chamber, a radiator circumscribing said furnace body, and als having in its floor a number of dummy ports, and a chute adapted to be interchangeably connected between any of the adjacent lower and upper ports to constitute a bypass for the escape of dust during the shaking of the furnace, and also for accumulated flue dust from the radiator into the ash-pit.

a. A hot-air furnace combining a furnace body providing a lower annular wall forming an ash pit and having a number of dummy ports, an annular radiator carried by said furnace body, and having in its floor a number of dummy openings and in its outer circumferential wall dummy openings adjacent thereto, a sheet metal shell inclosing the aforesaid ports, a door frame adapted to be interfitted with any one of the last my name, as attested by the two subscribing mentioned dummy ports to permit access to witnesses. said radiator from the exterior of said s 1e11, T and a dust chute leading from the port ad JOHN RIGHARDSOL' 5 jacent said frame to the nearest underlying Witnesses:
