HEATING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 368,201, dated August 16,1887.

Application filed March 17, 1887.

To all whom it may concern/H Be it known that we, OLNEY B. FULLER and XVILLIAM M. \VYCKOFF, of Detroit, in the county of lVayne and State of Michigan, have invented new and useful Improvements in Heating-Furnaces; and we do hereby declare that the following is a full, clear, and exact de scription thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to that class of furnaces wherein are combined the systems of hot-air and hot-water circulation for heating purposes; and the object of the invention is to construct a device for this purpose in a simple, cheap, and efficient manner, and that can be readily applied as an attachment to various styles of furnaces now in use.

The invention consists in the peculiar eonstruction, arangement, and combinations of the various parts, all as more fully hereinafter set forth.

Figure l is a central vertical section of our improved furnace. Fig. 2 is a perspective of the reservoir detached. Fig. 3 is a top plan of the distributingchamber. Fig. 4 is a similar view of the top of the reservoir.

In the accompanying drawings, which form a part of this specification, A represents a suitable base, which is provided with the usual firepot B, and ash-pit O, and may be of any of the known constructions.

Upon the top of the tire pot section is mounted the firebox D or combustion-chamber, preferably made of boiler-iron and provided with the feed-door E. The bottom of this fire-box should be lined with fire-brick, as shown. Near the top the fire-box is provided with an inwardly-projecting flange, (4.

F is a reservoir somewhat smaller in diameter than the fire-box, and is provided with the vertical fines I), the reservoir being c0n strueted upon the principle of a vertical-flue boiler. Mounted upon this reservoir F, and having communication with the water-space thereof by means of the pipes c, is a distributing-chamber, (3, through which passes a central flue, H. This distributing-chamber is provided with a flange, I, designed to fit closely in the upper end of the tire-box and rest upon Serial No. 231,250. (No model.)

its flange a, and at which point a sand or other suitable gas-tight joint should be made.

J is a jacket which surrounds the fire-box, and is provided with an opening, K, coincident with the feed-door E of the fire-box, the smoke and products of combustion of the latter passing up through the vertical ilues of the reservoir and over the top thereof to the flue H, and through the distributing-chamber to a proper exit pipe, which conducts them to the chimney.

L are suitable pipes rising from the distributing-chamber G, such pipes being employed for conducting the water to such, room or rooms as it is desired to heat'by hot-water circulation, the return to the boiler being through a pipe, M. Hot-air pipes N convey the heated air from the jacket J to the desired points.

The reservoir should be provided with any convenient expansion-chamber, as is required in all systems of hot water circulation for heating purposes.

It will be observed that the dues of the reservoir F are arranged mainly in a circle near the outer edge thereof, while pipes communieating with the distributing chamber are grouped near the center, the distributingpipes from the chamber G being located near its outer edge. This arrangement of pipes and fines assures a better circulation through the boiler or reservoir.

In practice, the parts being constructed and arranged substantially as shown, a fire being built in the furnace, the products of combustion pass up through the ilues of the reservoir, over the top of the same, and thence through the central flue of the distributirig-chamber, from whence they find exit to the chimney throughasuitable pipe. This necessarily high- 1 y and quickly heats the water in the reservoir, which is then circulated through the distributing-chamber and pipes, and returned to the boiler, as in all systems of this class of heat ing. The heat that is radiated from the firebox heats the air within the outer jacket, such heated air being distributed to the desired points by proper pipes. There is a space left between the outer wallsof the reservoir and the walls of the fire-box, into which space heat necessarily rises, and thereby greatly increasing the utility of the device both in heating the water in the reservoir and in radiating heat into the jacket.

It will readily be seen that the reservoir can be advantageously used as an attachment to any of that class of furnaces wherein there is a dome over the fire-pot, as in all of the so called surface burners.

' What we claim as our invention is 1. The combination, with the fire-box provided with inwardly-projecting flange a,of the distributing-chamber formed with a flange, I, designed to rest upon the flange a, the reservoir F, arranged beneath said distributingchamber and provided with vertical flu'es b, the pipes a, connecting said reservoir and chamber, and a central flue, H, passing through said chamber, substantially as and for the purpose specified.

2. The combination, with the fire-box,of the I
