I This invention relates to a steam heating furnace, and has for its object, broadly to provide such a construction that heat derived from coal as a fuel, when applied to the boiler for generating steam, will be utilized and not become wasted l in a degree heretofore experienced.

One of the specific objects is to provide such a construction for a furnace that finely divided inexpensive coal may be used for steam heating.

While the invention is designed Particularly for'heating residences, the features of construction found to be of advantage may be employed for use generally.

The invention consists of the new and useful construction, combination and arrangement of parts as described herein and claimed, and as shown in the drawings, it being understood that I may make changes in form, size, proportions and minor details, if desired, said changes being within the scope of the invention as claimed.

In the accompanying drawings, Fig. 1 is a View of the furnace casing in longitudinal section, the boiler being added. Fig. 2 is a side View of one of the grate-supporting bars or rods. Fig. 3 is a view of the same in transverse section, on

line S3 of Fig. 2.

Fig. 4 is a view of the casing in vertical section on line ii of Fig. 1.

Fig. 5 is a view showing the rear end-portion of the casing, the section being on line 5-5 of Fig. l.

Fig. 6 is a view of the furnace in transverse section on line G5 of Fig. 1.

Fig. 7 is a front view of the casing, and Fig. 8

is a View of the hood in transverse section the scale being enlarged. Fig. 9 is a transverse section on line 99 of Fig. 4.

Referring now to the drawings for a more particular description, the furnace consists, in part,

of an upright casing i0, rectangular in plan, provided at its rear end with an upwardly tapered draft-pipe member li, a rear door opening l2 for a rear door 13 (Figs. 1-5), a front door opening I l for a fire box 15 (Fig. 1), and a front opening 16 for an ash pit H, the door therefor being indicated at 18,

Numeral l9 indicates a horizontal, cylindrical boiler mounted on the open top of the casing, the front end of said casing having a concave recess 28 (Fig. '7) upon which the front end of the boiler is supported, the rear end of the boiler being supported upon a projection 2| of the rear wall of the casing, the weight of the boiler also being supported by the side walls of the casing for the reason that the upper edges of the side rows of fire-brick 22 (Fig. 6), said rows being 1 disposed in spaced relation, the narrower spaces 23 between the rows being those near to the front part of the fire-box, to conserve the consumption of coal, and the wider spacing 23 further to the rear part of the fire-box permitting ashes to more readily fall therethrough into the ashpit H.

The fire-bricks are adequately supported, and for this purpose grate-bars 24 and flanges 25 and it are used, the flanges 25 being disposed at the ends and the flanges 25 being disposed at the sides of the casing and preferably being cast as part thereof. It will be seen that the ends of the bricks of each row are supported on the gratebars 24 and upon the flanges 26, the ends of said bars resting upon the flanges 25.

In order that the rows of fire-brick will be maintained in spaced relation the bars 24 are provided on their faces with spacing-lugs 2'! as best shown in Fig. 2, and for preventing any sliding movement of the bars or rods 24 they are provided with heads 28, at their ends, and each head 28 is provided with a keeper 29 (Figs. 2-3) which engage in suitable apertures (not shown) which are provided for the end-flanges 25.

The body-portion of each bar 24 is of V-shape in cross-section so that it will not obstruct a movement of ashes to the ash-pit.

As shown in Figs. 1, 4 and 6, fire-brick 30 are provided for the opposed sides of the fire-box 15, each brick being supported on a flange 26, and the rear end of the fire-box I5 is provided with fire-brick 31 which are supported on a horizontal bracket 32, said bracket preferably being integral with the casing it.

Numeral 33 (Figs. -7), indicates a horizontal coal-receiving shelf or apron which projects forwardly from the opening it, approximately in line with the bottom of the fire-box 65 or grate, said shelf being provided with upright side-flanges 34, and at 35 is indicated a swingable hood of lesser area than the area of the shelf, said hood being provided with side flanges 36 which project downwardly and are normally disposed in the vertical plane of the flanges 34 of the shelf.

This hood includes a door 31 which is hinged to swing horizontally, and when moved to closed position it closes all of the opening Hi above the flanges 34 of the apron or shelf, and as described, that part of the opening it between the flanges 34 is open at all times for a movement of air into the furnace except when obstructed by coal which, I, during operation, is deposited upon said apron or shelf, and by use of a suitable tool may be manually pushed into the fire-box.

l5 Numeral 38 indicates a slide which is provided for the door 31 to control amovement of air to the fire-box l5.

At 39 is indicated a stop-element for the edges of the pipe-member II at the upper part of said 10 pipemember, and when the boiler is mounted on the casing its rear end will engage said stopelement.

Since the lower part of the rear opening l2 for the fire-box is disposed approximately in line 15 with the surface of the'fire bricks 22, and since this opening has a width corresponding to the width of the fire-box, it is obvious that clinkers, in the fire-box may be conveniently reached for removal.

20 The object in view in providing the horizontal row 3! of fire brick is to protect that part of the casing l adjacent to the draft-member ll below the rear end of the boiler.

It will be noted that the shelf 33 and hood 25 35 are of equal lengths, this length being equal to the width of the fire-box, and in operation, coal may be deposited on the shelf and upon the inclined top of the hood, if desired, and may be pushed into the fire-box as above described.

30 It will be seen that, during operation, the sides and rear end of the boiler will be exposed to the heat so that steam will be generated by use of a limited amount of coal. Numeral 40 indicates a damper for regulating the draft, and at 4| 35 are indicated passageways adjacent to the boiler at the sides of the projection 2| leading from the fire-box to the vertical, tapered draft-pipe.

On account of the improved means for heating as described, it is obvious that operation of the 40 furnace would be the same regardless of the contents of the boiler, and therefore I may use the invention for heating air instead of producing steam if desired.

I claim as my invention,-

1. In devices for the'purpose described, the 5 combination with a furnace-casing provided with a front wall-opening, a horlzontal grate and a door-controlled rear wall-opening, of a shelf provided with side flanges and projecting outwardly of the front wall-opening approximately in alinement with said grate and rear Wall-opening, and a hood swingably mounted on the casing normally disposed above with its sides in the vertical plane of the flanges of the shelf and closing a part of said front wall-opening.

2. In devices for the purpose described, the combination with a furnace-casing provided with a front wall-opening, a horizontal grate and a door-controlled rear wall-opening, of an outwardly projecting hood provided with side flanges and normally closing a part of the front wallopening and swingably mounted on the casing,

a shelf provided with side flanges disposed approximately in alinement with said grate and rear wall-opening and extending forwardly of the hood with its flanges in the vertical plane of the flanges of said hood.

3. In devices for the purpose described, the combination with a furnace casing having a front Wall-opening, of a shelf carried by the cas-. ing projecting forwardly of the wall-opening and provided with upright side flanges, and a hood mounted to permit horizontal swinging move-. ments on the casing at said wall-opening and having side flanges normally disposed parallel, above and closely adjacent to the side flanges of the shelf, the proportion of parts being such I that the shelf projects forwardly of the hood.
