EDWARD BACKUS, OF ROCHESTER, NEW YORK, ASSIGNOR TO MARY BAOKUS, OF SAME PLACE.

HOT-WATER H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 238,077, dated February 22, 1881.

Application filed March 29, 1880.

To all whom it may concern:

'Be it known that I, EDWARD BAGKUS, of Rochester, New York, have invented an Improved Hot-Water Heating Apparatus, of which the following is a specification, reference being had to the annexed'drawings, in which Figurelis a front elevation, partly in section, of my improved heating apparatus. Fig. 2 is a longitudinal central section of the same,

showing the parts to right of the central plane combination of a furnace having an exterior air-heating surface, an air-passage leading to said surface, a water-heater located in the firechamber, asecond water-heater connected with the first and located in the passage for the outgoing products of combustion, and a hot-water radiator located in the air-passage at a point in advance of the furnace and connected with the water-heaters.

Myimproved heating apparatus is shown in the accompanying drawings, in which A is the furnace, B B the radiators, G the inclosing brick-work, and D D D the hot-air pipes. The course of the air through the apparatus is represented by the arrows in Fig. l. p

The furnace A is constructed of sheet-iron, having a rounded upper surface, and having at either end heads or plates, through which openings are made for the entrance of the coal, the dischargeof ashes, and of the heated gases to the chimney or flue.

The fire-place door E and the ash-pit door F are preferably attached to a casting which projects through the casing of brick-work, and is riveted at its inner margin to the head placed at the front end of the furnace.

The direct-draft pipe Gr and the indirect- (No model.)

draft pipe H are connected with the rear furnace-head and communicate with the chimney or flue I. p

The furnace is divided about midway of its length by a vertical partition, L, which is bent backward, so as to afford support to the rear end of the grate-bars K, Fig. 2, and the firebrick a at the back end of the fire-space. The sides of the fire-space are also lined with firebrick b b, Fig. 2. The partition L rises some distance above the grate bars, so that the heated gases produced by the combustion are compelled to pass over the top of the partitionand downward through the coils of pipe M M on their way to the indirect-draft pipe H.

Within the fire-chamber and along the inside of the furnace are placed the coils of pipe N N, which communicate respectively at their lower ends with the upper parts of the coils M M. The upper part of the coil N communicates, through the pipe a, with the top of the radiator B. The lower part of the radiator B communicates, through the pipe P, with the lower-portion of the coilM. Provision is thus made for obtaining a circulation of water from the lower and coolest portion of the radiator through the coil M, which isbut moderately heated by the outgoing products of combustion, to the hot coil N, whence it is returned to the top of the radiator B by the pipe 0.

b, Fig. 1, is stand-pipe, which connects with the oirculatingpipes a a, and rises to any desired distance above the heating apparatus, for the purpose of maintaining the requisite pressure on the pipes and radiators.

I prefer to construct my improved heating apparatus with radiators and air-passages on each side of thefurnace, as represented in Figs. 1 and 3. The principle of my invention is, however, fully carried out by one radiator and a furnace.

In theaccompanyin g drawings my improved heating apparatus is represented with radiators and air-passages located on each side of the furnace, the radiators. being marked respectively B and B, the vertical partitions c and e, R and R, the fire-chamber coils Nand N, the circulating-pipes a and a, and the coils in the gas-outlet passage M andM.

The operation of the parts is the same on each side of the furnace, the radiator B coinmunicating through the circulating-pipe a.

' with the coil N, and this with the coil M,

and this coil with M, whence the pipe P extends to the radiator B, Fig. 3.

The furnace is inclosed in a suitable brickwork chamber, 0, having sufficient interior capacity for the radiators B B and the airpassages. The air enters through suitable openings at the base of the vertical side walls, (designated (1, Fig. 1,) and is heated moderately at first by passing through the radiator B, which consists of a number of sheet Ihetal heaters fastened together at top and bottom by suitable joints. The inner heater of the radiator B acts as a partition to compel the air to pass between the other heaters, and it rests at bottom on the brick-work partition 6. After passing through the radiator B the air descends along the partition It, and, passing through the openingf at the base of this partition, comes in contact with the hot exterior surface of the furnace, by which it is fullyheated,and thence is distributed through the pipes D to the various apartments to be heated.

In order to reduce the temperature of the outgoing products of combustion as much as possible, they are caused to pass downward through the coils of pipe M M on their way to the chimney. ()ne of these coils is connected with the radiator on one side of the furnace and the other with the radiator on the other side thereof.

It will be perceived that in my construction the coldest water'i. a, that which comes from the bottom of the radiators-passing into the lower part of the coils M M in the exit furnacepassage, is brought in contact with the coolest outgoing gases--a condition essential to the abstraction of the greatest amount ofheat from them; and it will also be seen that as the water circulates onward on its way back to the radiator, it is brought successively in contact with sources of heat of increasing tern perature, until it finally passes alongside of the fire itself, in order to prevent the fire-place from overheating.

The lower part of the radiator is connected with the lower portion of the heating-coil or other suitable water-heatin g device within the furnace, and the upper portion of the radiator with the upper end of the coil, in order to secure the proper circulation.

I am aware that air has been heated by admitting it directly between a fire-pot on one side and a hot-water coil on the other; also, that air has been admitted past a hot water coil at the base of a furnace directly upward against the exterior of the furnace-body.

I am also aware that various other forms of apparatus have been employed for the heating of air.

I claim 1. The combination of the furnace having an exterior airheating surface, an air-passage leading to said surface, a water-heater located in the fire-chamber, a second water-heater connected with the first and located in the passage for the outgoing products of combustion, and a hot-water radiator located in the air-passage at a point in advance of the furnace and connected with the first and second water-heaters, as described.

2. The combination of furnace A, the airpassage containing the depending wall B and wall a, the radiator B, located in the passage upon wall 0, and the two water-heaters, M and N, located in the furnace and connected with each other and with the radiator, as shown.

3. The improved furnace for heating air by a combination of direct and indirect radiation, the same consisting of the combination of the outside horizontal furnace-body, the grate, the walls a and L, above and below the grate, respectively, the water-coil N, located in the firechamber, and the connected coil M, located behind wall L in the base of the furnace.
