LEVI EVERETT BIXBY AND SEYMOUR A. PETERS, OF LOWELL, MASSACHUSETTS.

HOT-WATER HEATER.

Patented June 30, 1908.

Application filed January 31, 1908. Serial No. 413,626.

To all whom it may concern:

Be it known that we, LEVI EVERETT BIXBY, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, and SEYMOUR A. PETERS, a subject of the King of Great Britain, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented new and use ful Improvements in Hot-Water Heaters, of which the following is a specification.

This invention relates to hot water heaters, the object of the invention being to provide a simple, economical and effective heating apparatus for domestic use which may be readily set up in any building and operated at a minimum expense and with little or no care or attention, the apparatus being thoroughly automatic in operation.

With the above and other objects in View, the nature of which will more fully appear as the description proceeds, the inventlon consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings :-Figure 1 is a sectional elevation of the apparatus complete, shown applied to a building. Fig. 2 is an enlarged vertical, diametrical section through the furnace, taken on the line 22 of Fig. 3. Fig. 3 is a similar view taken at right angles to Fig. 2. Fig. 4 is a sectional plan view of the furnace taken on the line 44 of Fig. 2.

Referring to Figs. 2, 3 and 4 of the drawings, wherein the furnace is illustrated in detail, the furnace is seen to comprise a lower body portion 1, and a head or to portion 2 which is preferably of relatively large diameter and which has connected therewith a smoke flue 3 which leads oif to the chimney indicated at 4 in Fig. 1.

In the lower portion of the furnace is arranged a grate 5 of any suitable construction and located above the grate is an inverted frusto-conical fire box 6, the upper edge of which is coincident with the line where the upper and lower portions of the furnace body come together as clearly shown in Figs. 2

and 3.

Extending centrally and vertically of the fire box 6 is a tubular division wall 7, or in other words, a central dividing partition which is formed as shown in Figs. 2 and 3 of a suitable length of pipe which is given the serpentine or coil of formation, the sections or convolutions being arranged one above the other while at the lower end the said pipe is extended laterally out through the fire box and side of the furnace to constitute the water inlet or feed pipe 8.

At its upper end the coil or pipe 7 dis charges into a water heater or back 9 which is arranged at the back of the furnace just opposite the fuel door 10 and about in line with the point of junction between the upper and lower parts 2 and 1, the said water heater acting as a fire bridge heat absorber located directly above the top ofthe fire pot.

Located just over the fire pot is another serpentine coil or pipe 11 one end of which is in communication with the water heater 9. This coil 11 projects directly over the fire pot and is set at an inclination as clearly shown in Figs. 2 and 3 inclining upward toward the fuel door 10 so as not to interfere with the proper feeding of the furnace. After forming the serpentine crown coil 11, the pipe is then shaped into a helical coil 12 of any desired number of convolutions and after said coil has been formed, the pipe is lead out of the top portion of the furnace where it forms the outlet or circulating pipe 13. This pipe 13 leads to and through any desired number of radiators 14 and 15 located at suitable points in the buildim and from said radiators a return pipe 16 leads back to the feed or inlet pipe 8. A supply pipe 17 leads from an ordmary automatic flushing tank 18 to the inlet or feed pipe 8 as shown in Fig. 1 and the overflow connection 19 of the tank '18 also leads into the pipe 17, thereby providing for a continuous supply of water to the circulatin pipes of the eating apparatus.

33y arranging the serpentine coil 7 contrally or vertically within the fire pot 6, the fire pot is divided into two compartments either one of which may be fed with fuel independently of the other, thus enabling the furnace to be run on a half or whole fire according to the temperature of the atmosphere. This makes a simple and economical arrangement which will be found of great value. Furthermore, the water heater 9 and the inclined serpentine crown coil 11 are subjected to the direct action of the heat and products of combustion which is productive of a very rapid heating of the water contained in the circulating p1 es, and the quicker circulation of hot water tlirough the system.

20 designates the drain cock by which the entire system may be drained when necessary.

Having thus described the invention, what is claimed as new, is

1. In a hot water heating apparatus a furnace embodying a fire box, and a serpentine coil extending centrally and vertically within the fire box and communicating with the circulating pipes.

2. In a hot water heating apparatus a furnace comprising a fire box, a serpentine water coil extending centrally and vertically within the fire box and communicating with the circulating pipes, and a crown coil extending over the fire box and communicating with the coil in the fire box and also with the circulating pipes, substantially as described.

3. In a hot water heating apparatus a'furnace, a firebox therein, a serpentine coil extending centrally and vertically within the fire box and communicating with the circulating pipes, a crown coll extendlng over the fire box and communicating with the circulating pipes, and a water heater arranged between and communicating with said coils and located at or near the top of the fire box, substantially as described.

4. In a hot water heating apparatus a furnace, a fire box therein, a serpentine coil'extending centrally and vertically within the fire box, a crown coil extending over the fire box and communicating with the aforesaid coil, a superimposed coil extending upward from the crown coil and communicating with the circulating pipes and means for feeding water to said pipes.

In testimony whereof we affix our signatures in presence of two witnesses.
