HEATING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 334,781, dated January 26, 1826. Application filed June 16, 1884. Serial No. 134,976. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID L. J ONES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating- Furnaces, which are fully set forth in the following specification, reference being bad to the accompanying drawings, forming a part hereof, and in which- Figure l is a front elevation. Fig. 2 is a front elevation, partly in section. Fig. 3 is a plan view of section below the plane 3 y of Fig. 2. Fig. 4 is a side View of the radiator B, from which the larger portion of its inner wall is removed so as to show the flues b and partitions b If 1) Nb. Fig. 5 is a vertical central section through the center of both furnaces, as shown in Fig. 3 in plan.

Like letters of reference'indicate like parts.

The object of my invention is to improve the construction of heatingfurnaces, so as to, first, increase the heating-surface within a given cubic capacity; second, to combine two or more fuel-magazines with one radiator, and, third, to control the heat of such furnace more perfectly and in a more economical manner than heretofore; also, in arranging the parts so that both furnaces, whenever two are used, can be fed from the same side of the furnace through doors placed side by side, thereby being enabled to set the furnace where others with opposite doors could not be used for want of room, and, combined with such furnace or furnaces, a radiator of elliptical horizontal outline, through which the smoke and gases must pass into the chimney, said radiator being provided with interior and exterior radiating walls and open fines passing vertically through said radiator, also partitionwalls having passages whereby the smoke and heat are caused to pass through a circuitous route to the chimney, all as clearly set forth.

In the drawings, a a are the fire-pots, pro vided with grates a over the ash-pits a Said fire-pots extend upward to the fire-doors a and beyond said doors form heating-drums b, extending to the top of the radiator B. From the upper end of said drums extend smokeflues c 0, uniting in this case into a main, 0, which discharges the smoke between the two walls 2; b of a radiator, B, surrounding the drums b, and of about the same height,

as shown in dotted outline in Fig. 1. The upper and lower ends of said radiator are pierced with flues b somewhat less in external diameter than the space between the walls b 6*, leaving a passage, 0 andat intervals more or less numerous are placed deflectors b b b b, which extend from wall to wall and about half-way across the longitudinal space between the ends of said radiator. Said deflectors are so arranged as to be alternatelyiu contact with the upper and lower ends of the radiator, and serve to deflect the smoke and heat into a more circuitous route. A partition or diaphragm, b is placed between the main 0 and smoke-pipe b, which causes the smoke to pass as indicated by the arrows, and in said partition is an opening, 1), controlled by a valve or damper, f, (shown as a heavy broken line in Fig. 2,) worked by a rod, g, passing out through the front. Said valve is opened when starting a fire, or when the heat becomes too great, so that the smoke or heat may pass directly from the main 0 into the pipe I). The fuel-doors h and ash-pit doors i are each provided with a damper,j, for the purpose of effectually controlling the draft and heat of the furnace.

The above-described parts are surrounded by a jacket, d, having hot-air flues e, and are arranged in the usual way to receive the cold air from the bottom through a flue, Z, in the base It.

The arrows in Fig. 2 show the course of the cold air as it rises and receives heat by coming in contact with the heated parts of the furnace.

By the combination of alarge radiator, B, with one or more fuel-magazines, greater or less heat may be obtained, because but one fire-chamber may be working at its full capacity and the other at any degree less; or both may work at variously-reduced capacity.

hen at any time the heat becomes too great, the damperf may be opened either fully or partly, so as to allow the heat to'pass directly into the smoke-flue, instead of giving out its heat through the radiator; also, where only one fire-chamber is going, it may in another way be regulated, which is by the own, or by those of dampers j and doors of its ICO the adjoining fire-chamber, at pleasure, and thereby to any desired shades of nicety.

In the sectional view of Fig. 2 the arrows shown behind the deflectors are shown dotted, while those in front are shown full, or part of them beyond the deflector are shown dotted, thus showing the direction of the current of heated air.

What I claim is- The fire-chambers a a, provided with drums b b, and pipes c c and c, in combination with radiator B, having radiating-surfaces b b", deflectors and tubes, diaphragm b damper f, and rod g, passing out over the furnace-doors, flue b, jacket d, having pipes e, and doors h 2', provided with dampers j, substantially as specified.
