SPECIFICATION forming part of Letters Patent No. 672,688, dated April 23, 1901.

Application filed June 11,1900. Serial No. 19,819. (No model.)

To all whom. it may concern:

Be it known that 1, JAMES Ross VANCE, of Geneva, in the county of Ontario and State of New York, have invented new and useful Improvements in Steam and Hot -Water Heaters,

of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention consists in a new constructioning channels in their rear faces, by which the water-leg is protected from direct contact with the incandescent coals and the products of combustion are brought quickly into uniform contact with the entire outer as well as with the inner surface of the boiler, thus obtaining the maximum of fire-surface Without complicated flues, baffle-plates, 850.

My invention is clearly illustrated in the accompanying drawings, in which the same reference-numerals indicate the same parts in all the figures.

Figure I is a side elevation of a furnace constructed according to my invention, portions being broken away and portions being shown in section; Fig. II is a corresponding vertical Fig. III is a cross-section on line III III of Fig. I. Fig. IV is an isometric view of a single tile. Fig. V is an isometric view of one of the podestals detached.

In the figures, 1 indicates the base, forming an ash-pit provided with the usual door 2 and having the flat upper plate 4, provided with flanges 5 and 6 for receiving and sustaining the outer shell or jacket 11 and the tiles 8 8. To this plate are secured the blocks or pedestals 10 10, of suitable form and number to support the boiler 7 above the plate, leaving a space under the lower edge of the water-leg 12 for the passage of the products of combustion. Such support may be afforded by a perforated ring or other suitable device; but I prefer separate pedestals bolted to the plate, of which a suitable form is shown in Fig. V, having flanges 13 for the securingbolts 14, a bed 15 to support the boiler, and an outer flange 16 for retaining it in position.

18 indicates the inner shell of the boiler, and 19 its outer shell.

The lower part of the fire-box is lined with tiles 8 8, of fire-brick or similar fire-resisting material, fitted to the flange on the base-plate and having channels 21 21 on their outer surfaces next the water-leg. These tiles may be variously constructed and of such length, width, and thickness as may be desirable, their essential features being that they line the lower portion of the water-leg, protecting it from direct contact with the fire, and are provided with channels on their outer surfaces, through which the products of combustion, having impinged on the inner arch 22 of the com bustion-chamber, pass down in contact with the inner surface of the water-leg, under the lower edge of the boiler, between the pedestals, thence up and around the outer surface of the boiler through the annular flue 23 within the shell 11 and out of the pipe 25.

If more water-space is desired, one or more water-tubes 26 26 may be arranged connecting the water-legs at such distance above the fire as may be desirable, as shown in Fig. I, or arranged extending above the fire with a dead end, as in Fig. II.

The other parts of my furnace are of usual construction. 30 indicates the water-gage; 31, the steam-gage; 32, the automatic regulator to the damper 33; 34, the steam-pipe; 35, the clean-out door; 36, the grate, of any suitable construction, and 37 and 38 doors to the combustion-chamber and fire-box.

My boiler is simple and economical to construct. Expensive and complicated fines and baffie-plates are avoided. The water-leg is protected from direct contact with the fire and the outer edge of the fire itself not cooled by con tact therewith, so that combustion and incandescence throughout the whole fire is uniform and regular. The maximum of incandescence is not confined to the center of the fire, as in most boilers, and thus the maximum of uniform heat is obtained from the fuel, heating the entire inner surface of the boiler uniformly. The products, still at a high temperature, pass down the channels in contact with the water-leg and are imme- 4o the water-leg from the fire, said tiles being diately brought in contact with'the entire exterior of the boiler. Thus both surfaces are practically fire-surfaces and the less effective flue-surfaces are entirely avoided. The tiles are uniformly heated on both surfaces, avoiding the danger of warping and breaking.

f My boiler is easy to construct, to ship, and to set up on its separate base, needs few repairs, is easy to repair when necessary, is easily cleaned, and is very durable. It is eflective in operation, and from its simplicity of form is comparatively light, unnecessary metallic parts being avoided.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, 1's- 1. In combination in a heater, a suitable base, a boiler supported thereon having a lower annular water-leg and openings near the lower edge of the water-leg, an external jacket forming a continuous flue around the boiler, and a series of tiles of refractory material arranged around the fire-box, in contact with the inner surface of the water-leg, having vertical grooves on their outer surface to conduct the products of combustion down in contact with the inner surface of the water-leg to the openings and the outer flue.

2. In combination in a steam or hot-Water heater, a separate base having a Hat top formed with flanges for maintaining the position of the upper portionsof the heater set thereon, a boiler also supported on the base having the lower annular water-leg inclosing the fire-box formed with openings at or near its lower edge, an external jacket also supported on the base inclosing said boiler and forming a continuous flue around its outer surface, a series of fire-brick tiles lining the fire-box and protecting the lower portion of formed with grooves on their outer faces to permit the passage of the products of combustion from the combustion-chamber down to said openings and the outer flue.

3. In combination in a steam or hot-water heater, a separate base having a fiat top formed with flanges for maintaining in position the upper portions of the heater set thereon, separate pedestals secured on said flat top to support the boiler and elevate it above said base, the cylindrical boiler having an annular water-leg fitted to said pedestals, a sheet-metal jacket supported on the base to inclose the boiler and form a continuous flue around its outer surface, a series of fire-brick tiles forming a lining around the fire-box to protect the lower portion of the Water-leg from contact with the fire, said tiles being formed with grooves on their outer surfaces, in contact with the water-leg, to permit the downward passage of the products of combustion from the combustion-chamber stapes down and under the water-leg to the exterior 4. In combination in a steam or hot-water heater, a base of cast metal having an annular flat top, concentric flanges formed on said top to maintain the position of the upper portion of the heater set thereon, separate pedestals secured on said top plate to support the boiler, a cylindrical boiler having an annular water-leg fitted to said pedestals so as to leave openings between the water-leg and the flat plate for the passage of the products of combustion, a suitable grate arranged at about the lower edge of the water-leg, a series of tiles of refractory material supported on said base and held in position between the inner flange and the water-leg, protecting the water-leg from contact with the fire, said tiles being formed each with a vertical channel on its outer surface to permit the passage of the products of combustion downwardly from the combustion-chamber under the lower edge of the boiler to the surrounding flue.

5. In combination in a steam or hot-water heater, an annular base of cast metal having an annular, inwardly-extending, flat, upper margin, two concentric flanges formed on said flat margin to maintain in position the upper portions of the heater supported thereon, a pluralityof separate pedestals bolted to said flat margin between said concentric flanges to support the boiler, said, pedestals being formed with lower, securing-flanges, an up per, flat bed for the boiler and an outer flange for fixing the position of the boiler on said bed, the cylindrical boiler having an annular water-leg fitted to said pedestals and elevated thereby a short distance above the upper margin of the base, leaving spaces for the passage of the products of combustion, a suitable grate arranged below said water-leg, a series of fire-brick tiles supported on said base and held in position between the inward concentric flange and the water-leg forming a continuous lining to protect the water-leg from contact with the fire and being formed with corrugations on their inner surfaces and each with-a vertical channel from one end to the other on its outer surfaces to permit the pets sage of the products of combustion downwardly from the combustion-chamber under the lower edge of the boiler to the surrounding fine, water-tubes extending from the water-leg into the combustion-chamber and a sheet-metal shell surrounding the boiler and forming a continuous outer flue.

In testimony whereof I have hereunto signed my name.
