HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 501,974, dated July 25, 1893. Application filed May 11, 1892. Serial No. 432,629- (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM VANDERMAN, of Willimantic, in the county of WVindham and State of Connecticut, have invented certain new and useful Improvements in Hot- Water Heaters, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a combined boiler and furnace that is more particularly adapted for providing hot water to be used for heating dwelling houses and public buildings, and one in which there will be secured a uniformity of heat with economy of fuel.

To this end my invention consists in the details of the several parts making up the hot water heater as a whole and in their combination as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure 1 is a detail view in vertical section through the heater the line of section passing through the connecting water fiues. Fig. 2 is a detail view in vertical section through the heater on a plane at right angles to the plane of view of Fig. 1. Fig. 3 is a detail plan view of one of the boiler sections. Fig. 4 is a detail plan view of one of the upper boiler sections.

My improved apparatus comprises a furnace and a boiler made in horizontal sections that are secured together as by means of bolts and provided with fiues for the circulation of flame, and gases of combustion and with other flues for the circulation-of the water through the boiler parts.

In the accompanying drawings the letter a denotes the base of the boiler and furnace made preferably hollow so as to form an ash pit and open at the top for the reception of a grate a. On this base the boiler is supported, the lower section b containing the fire pot 1). Above this are arranged the sections 0, d, e and f that are secured together by means of bolts passing through the flanges that project from the top and bottom edges of the sections. The second section 0 has a re-entrant bottom 0 forming a heating drum that directly overlies the combustion chamber and into which the heated products of combustion rise direct from the mass of burning fuel in the fire pot. The bottom of this section 0 forms the crown sheet of the boiler. the section d is recessed so as to form a deflector chamber (1 and the lower surface of the upper section f has also a likedeflector chamber f. Through each of the sections above the bottom section, flues g are formed near the outer edge of the boiler and they register with each other so as to form a continuous flue from the combustion chamber to the deflector chamberf', and'the products of combustion rise directly through these flues. A central fine 1' extends from the deflector chamber d through the superimposed sections and connects directly with thesmoke stack or chimney. In case a direct draft is desired a damper i in the side of this central flue is opened and this gives a direct outlet from this chamberf' and of course from the flues communicating therewith. A second series of tubes extend between the two deflector chambers d and f and when the damper t" is closed an indirect draft is created, the flames rising through the flues g descending through the tubes 9 and then rising through the central flue 2'. By this construction of parts the water surrounding these flues in the several sections is thoroughly heated and a large percent. of the heat caused by the combustion of the fuel is utilized.

Connections are made for the usual flow pipes it from the upper part of the water chamber of the boiler and a return connection Z is made with the water chamber of the boiler near its bottom.

A handle not shown for operating the damper z" extends through the walls of the section and is arranged on the outer side of the furnace in a convenient position to enable the damper to be moved.

The water chambers of the several sections are connected by means of water ways at that are formed in the cylindrical projections pref erably formed in any desirable number on the peripheries of the boiler sections, and so located on each section as to overlie one another when the sections are bolted together and form a continuous water way. The water space within each section, of course, communicates freely with the vertical water ways by having the side of the tubular way open. The result of this construction is that a free The under side of flow of water is established from the lower sections through each of the intermediate sections to the upper end of the boiler and out ihrough the flow pipes to the pipes of circulaion.

As already explained a thorough contact of the water with the heated surfaces is provided for by the construction of the several flues providing for the indirect movement of the flames and heated gases of combustion through the uptake.

I claim as my invention 1. In combination in a sectional boiler and furnace the lower section forming the firepot, an upper section 0 having a number of vertical flues located near the sides of the fire-pot and having a re-ent'rant bottom forming a chamber extending above the flue outlets, all substantially as described.

I11 combination in a sectional boiler and furnace the lower section forming a fire-pot, the sections overlying the fire-pot, a series of vertical fiues extending from the fire-pot to a deflector chamber. in one of the upper sections, a series of inner flues extending from the upper deflector chamber to a lower deflector chamber in one of the intermediate sections, and a central flue extending upward from the lower deflector chamber, all substantially as described.

3. In combination in a sectional boiler an furnace the lower section comprising the firepot, an upper section having a re-entrant bot tom forming a combustion chamber, a deflector chamber located below the bottom section, the Vertical flues extending from the fire-pot to the deflector chamber, a central flue extending through the upper sections of the boiler and a damper located in the side of said flue and communicating between the upper deflector chamber and a central flue, all substantially as described.

4. In combination in a sectional boiler and furnace the lower section comprising the firepot, the crown sheet section having a re-cntrant bottom forming a combustion chamber, a deflectorchamber located below the dome section of the boiler, a lower deflector chamber located between intermediate sections of the boiler, vertical flues extending from the fire pot to the upper deflector chamber and from the upperdeflector chamber to the lower and a central smoke flue extending from the lower deflector chamber through the upper sections of the boiler, and the damper located in the side of the central flue and communieating with the upper deflector chamber with a handle extending to the outside of the furnace, all substantially as described.

5. In combination in a sectional boiler and furnace, the lower section comprising the firepot, the upper sections overlying the fire pot, a deflector chamber located below the dome section, a deflector chamber located between the intermediate boiler sections, a series of flues extending from the fire-pot to the upper deflecting chamber, an inner series of tubes extending between the deflector chambers, a central smoke flue extending from the lower deflector chamber, and the water-ways extending between the several sections and coinmunicating with the water chambers therein, all substantially as described.

WILLIAM VANDERMAN.
