TO WHOM IT MAY CONCERN:

Be it known that I, ADAM Enxs'niof Milwaukee, in the county of Milwaukee, and State of Wisconsin, have invented certain new and useful improvements in Heating Apparatus; and Thereby declare the following to he a full, clear, and exact description of the some, reference being bad to the accompanying drawings, in whichv Figure 1 is a vertical central section of an apparatus constructed in accordance with my invention; and

Figure 2 is a like section of a modification of the same. i v

Figures 4 and 5 are transverse sections of the apparatus, shown in figs. 1 and 2 respectively.

The object of my invention is to utilize the hcated product of combustion which in ordinary stoves is drawn off directly through a chimney flue into the outside air. A great amount of heat is thus wasted which might be applied to heating other rooms or apartments, or to more thoroughly heating the apartment in which the furnace or stove is located.

,My invention consists in a heating apparatus in which fines are formed for the passage of the products of combustion and air to be heated in the manner hereinafter described, and which is capable of being readily applied to or used in connection with stoves or furnaces of ordinary construction.

Thisappuratus may be either attached to the stove itselfor placed at any point on the smoke pipe or flue, so that if the stove be in one room the pipe may extend through the wall into the next adjoining room, or through the ceiling into the room above, where the heating apparatus can be connected or joined to the pipe so as to utilize all the heat passing up through it, and to thoroughlywarmthe'room. I

The apparatus consists of a drum or casing enclosing an outer helical or spiral flue, through which the smoke and heat pass from the stove when desired. This annular flue encloses another flue (the two being entirely separate and having no communication with each other) which communicates with the outside air. There may he alsi) a third due, if it be desired, either enclosed within the air flue or placed on one side of the apparatus, which is prorided withn damper or valve, and like the outer-helical due is intended to receive the products of combustion. v V f When the apparatus is to be used for heating purposes the damper is turned so as to close this flue, which directs the products of combustion up through the outer winding passage, heating the air in the inner fine and at the same time causing the heat to radiate from the exterior of the drum. i

When no more he-fat is required, or it is desiredtodireot the heat to another room still further on, the damper or valve above mentioned is opened, and the smoke and heat pass up through the straight or tubular fine, and are carried ed to the point where they are to be used. i i

In the drawings, I have represented twomodifications of my invention. The apparatus shown in fig. 1 is intended to he applied to the top of an ordinary stove, or it may simply hare a fire-pot or chamber formed under it. It consists of an outer drum or casing, in which is formed a; spiral or helical flue, a, priclosing the air flue b. The two flues have no communication with each other. The air line is closed at the bottom, and

communicates with the exterior air by means of a tube, 6', which passes'through the helical fined and drum A; the flue a is of course open at the bottom to receive the heat, &c., from the fire, and at its upper end opens into the side flue c, which is putin communication with the lower part of theennular chamber surrounding the air flue I; by means hf the branch pipe 0. A. damper, d, is placed in the side flue, by means of which the products of combustion may be either drawn ofi' directly through this flue or directed into the helical fine or radiator 01.

The operation of the apparatus is as follows: Whenthe damper d is closed, the heated products of crimbustion, passing up through the open bottom ,of the chamber A, will be carried through the spiral or helical flue a. In their course through this annular and spiral chamber they will not only caluse the heat to radiate from the exterior drum A, but will heat the air within the inner drum or flue b, which air becoming ritrefied ascends, its place being supplied by the cold air drawn in through the pipe b. After passing up through the helical flue, the products of combustion pass out into the pipe 0, The heated air in the due I) is discharged from the open mouth of the line, or is conducted off to any desired point by meansiof additional-length of pipe fitted over the top of the flue. If it be now desired to put a stop to the heating of the air, the damper cl is Opened, in which case the products of combustion will of course be drawn off in great part, if not altogether, through the shorter and more direct flue or passage 0. By this means they are kept from'contact with the inner flue b and helical drum a, and can be conducted ofl rapidly and withoutany'cons'iderable loss of heat' to other rooms greqniring to be heated. In such case apparatus may be employed similar to that shown in fig. 2, in which the upper and lower ends a of the drum or casing A are contracted so as .to fit the pipe to which they are applied. The relative positions and general arrangement of the spiral flue a and air flue b are unchanged, but instead of placing the side flue c on the exter pr of the drum A it is placed within the air fiue, by which arrangement the apparatus is divided up into three concentric chambers. The flue c, as in fig. 1, is provided with a damper, d, by operating which, as before explained, the products of" combustion are either drawn up directly through the centre flue or directed into the helical flue or radiator. In order. to admit of the free dis- ,charge of the heated air the casing A is divided into two sections, the internal arrangement of which is the same, connected by tubes or pipes f opening into the helical passage or flue in the upper and lower sections.

The inner or direct smoke flue 0 extends uninterruptedly from one end of the apparatus-to the other. Under this arrangement the annular air-chamber b is entirely open at the top, so that the air drawn in through the tube or throat b when heated is free to escapefiom the annular openings 6 at the top.

" It will be seen that in this modification the inner flue c is in reality theordinary smoke flue or pipe, surrounded as described by an annular air-chamber and helical flue. By connecting the helical flues by pipes f,

as represented, the heated products of combustion are not onlyenabled' to pass with facility from the lower section to the upper, but the exterior heating surface is considerably increased in area. v

It will be seenthat the two forms of apparatus, shown in illustration of my invention, are essentially the same in principle. They are each provided with a flue for carrying of the products of combustion with as great rapidity and as little loss of caloric as possible; and they have a helical passage through which the products of combustion pass more slowly, .so as to give out or radiate a greater amount of heat. These two fines are connected in such manner that the heat may be directed either wholly or partially through the one or the other according as a greater or less degree of heat is required, and they are arranged and combined in a radiator or drum formed so as to admit of their ready application to any fire-pot, or stove, or pipe of ordinary construction.

Having described my invention and the manner in which the same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, is

1. The herein-described heating apparatus, the same consisting of a drum or radiator'capable of.being applied to a stove or pipe of ordinary construction, and provided with fiues arranged substantially in the manner and for the purposes herein shown and specified. I

2. The combination and arrangement of the inner or direct smoke flue, and annular air-chamber surrounding the same, with the outer helical flue or radiator, and the pipes or tubes for connecting the sections into which the said flue is divided, substantially as herein described.

In testimony whereof Ihave signed my name to this specification before two subscribing witnesses.

ADAM ERNST.
