Application filed January 23, 1897. Serial No. 620,466. (No model.)

Beit known that LWILLIAM HENRY RILEY,

tions, combinations, and arrangements of parts, as will be hereinafter fully described' and claimed.

In the accompanying drawings, forming a part of this specification, Figure l represents a vertical cross-section through the fire-box and heating-chamber and smoke-flue of a furnace constructed -in accordance with my in- Fig. 2 represents a horizontal crosssection of the furnace. Fig. 3 represents a horizontal cross-section of vthe same through the base thereof on the line l 2 of Fig. l, and Fig. 4 represents another manner of connecting the smoke-pipe With the furnace.

A represents a furnace; B, a base therefor; O, a iirebox, and D a smoke-pipe.

' The furnace A is formed with a shell or heating-drum A', preferably constructed of metal and secured at its lower end to the base B, the said shell extending through the said base -to the bottom thereof, as illustrated. IIot-air pipes or tubes ct Ct, extending through the shell A and through perforations in the top and bottom thereof, are adapted to convey cool air from below the furnace u p through the same, whereby it becomes thoroughly heated and ready'for use.

The base B preferably extends around the shell A except at the front and is of a generally rectangular shape and hollow. It com munica-tes with the interior of the shell by openings a a in the sides thereof. The

4smoke-flue D is secured at its lower end in an opening d in the top of the base B just in the rear of the shell A and extends upward parallel with said shell. The flue D is connected with the interior of the shell by a short.,

pipe or flue d. This pipe d may, if desired,

be provided with adamper, as at d2, by which the draft in the said Lline may be controlled. This damper d2 may, however, be dispensed with and the draft be controlled by the use of small doors b l) in the sides of the base B. These doors b h also afford access to thefinterior of the base B when it is necessary to clean the same.

In the front part of the shell` A is. arranged the re-box O, which is muchsmaller than the shell A' and preferably secured to the front wall thereof. The door 'c of the firebox is arranged about halfway of its height and in the lower part of the front wall of the shell A. The fire-box O is provided with a grate c', preferably about flush with the bottom of the shell A',

The re-box Oeis lined with fire-brick c2, which extendsa little above the box O proper. In this extended portion are form ed port-holes or apertures c3 c3, and fire-brick or tiling c4 is placed over the top of the said extended portion, so that the heat is deliected and passed out the ports c3 c3, An ash-pit c5 of ordinary form is secured in place beneath the grate c.

The furnace proper, comprising the shell A and the base B, is preferably incased in brickwork constructedabout the same, which supports the shell A in such a manner as to ad-` mit cold air from a duct or other lneans to the lower ends of the tubes a a.. The brick` work is extended above the top of the shell a sufficient distance to form a hot-air reservoir E, the top of which is covered by a met-al plate e, and brick, gravel, or other similar material may be placed on top of the plate c to prevent the possibility of tire. The air after entering the space below the furnace passes up through the pipes a o, Where it becomes heated, into the reservoir E, whence it may be led away by suitable pipes to register in different parts of a building to heat the same. Y If preferred, the brickwork may be dispensed with and the same purposes accomplished by the use of a metal casing.

One or more Water heaters or reservoirs F may be riveted to the shell either on the outside or ou the inside, but preferably on the inside, as shown in the drawings. This casing' or reservoir F is supplied with water by a suitable pipe connected with a tank or any suitable supply. Pipes leading from this res- IOO ervoir supply hot water for household purposes at any desired point.

It Will be noticed that by the use and arrangement of the air-pipes a d the air to be heated is exposed to a large amount of heating-surface and has a chance to become thoroughly heated before it is used.

In starting a fire the direct draft through the short pipe or flue d is used until the lire is Well under Way. Then the draft is changed either by the manipulation of the damper or the doors l) l), so as to be no longer allowed to pass directly to the smoke-pipe D, but is forced to go down among the pipes ct a into the base B and thence into the main flue D. In this Way the tubes oI a are kept Very hot and thoroughly heat the air passing through the same.

In the modification shown in Fig. in place of only the base branch pipes J J may be used, communicating With the interior of the shell at the bottom thereof on both sides, as at jj, and leading to the smoke-flue J2 in the rear, as at j In this construction the course of the draft Will be the same as hereinbefore described.

My furnace is found to be Very cheap of construction and most effective in heating quality and is yet Very economical in the use of fuel.

IIaving described my invention, what I desire to claim and secure by Letters Patent l. In a furnace, the combination of a shell, air-heat-in g tubes extending through the same, a hollow base portion secured to the shell eX- ternally thereof, the said shell extending through the said base to its bottom and having openings in its sides to establish communication between the shell and the base, and a draft-flue connected with the shell and the said base, and means for causing the draft to pass directly to said flue from the shell or indirectly from the shell through the external base at Will, substantially as described.

2. In a furnace the combination of a shell having air-heating tubes passing through the same, a fire-box Within said shell, comprising an outer casing, a lining of fire-brick extending above the casing and provided with ports or apertures opening into the interior 0f the said shell and atop portion of tire-brick, and a draft-Hue, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two Witnesses.

WILLIAM I-IEN RY RILEY.
