SPECIFICATION forming part of Letters Patent No. 415,819, dated November 19, 1889.

Application filed February 3, 1887. Serial No. 226,348. (No model.)

T all 107mm it may concern:

Be it known that LJoHN BoMA,of the city of Rochester, in the county of Monroe and State of New York, have in vented a certain new and useful Improvement in Heaters; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

My improvement relates to a portable water-heater in which the heating agent is gas, oil, or other suitable material, and in which a system ot pipes is used through which the water circulates and becomes fully heated in its passage, and is finally carried off through a central discharge-pipe.

The invention consists in the construction and arrangement o'f pa1ts hereinafter more fully described and definitely claimed.

ln the drawings, Figure l. is a central vcrtical section of the heater. Figs. 2 and 3 are horizontal sections of same respectively in lines and y y ot Fig. l. Fig. 4 is an enlarged horizontal section through one of the combined gas and air pipes. Figs. 5 and 6 arc views similar to Figs. l and 2, but showing a modification in the water-pipes.

A indicates a hollow base, which is divided by a series ol circular partitions a d, making annular compartment-s in the form of .rings all the way around. These compartments serve to receive the gas and air from the injection-pipes and discharge same up through holes b l) made through the top plate of the base where it is burned to produce the heat.

B B are the air and gas pipes, which pass horizontally Jthrough the compartments on one side of the base. Two sets of these pipes are used. The outer pipe B of each set is an air-pipe and the inner one B a gas-pipe, the latter being provided with a cock c and the outer end of the air-pipe being provided with holes (l d to admit the air. The air-pipe is also provided with openings f f, which open into the compartments of the base.

is the dome, made hollow and water-tight and provided on the inside with a water-tight raised cap D, which covers the central part ot' the lower plate of the dome7 as shown in Fig. 1.

E is a central discharge-pipe attached to the bottom plate of the dome under the hollow cap D, thence extending centrally down through the base and carried to any suitable receptacle for receiving the heated water.

G is a sheet-metal hollow annular jacket forming the body ot' the heater, the same being of cylindrical form, as shown, and closed at top and bottom. This jacket fills only a portion of the vertical length between the base and dome, leaving draft-passages g and h at bottom and top to support combustion and allow proper draft.

H H H are a series ot pipes through which the water circulates. Each of these pipes is attached at the top to the bottom plate of the dome, as shown at yi, and thence extends down and opens into the top ot' the jacket G. The pipe then connects with the bottom of the jacket, as shown at i', thence it is carried in alternating bends up and down from base to dome, and iinally ends at 'i2 under the hollow cap D. These series of pipes are arranged in radial lines through the whole heater, as shown in Fig. 2, and the gas-holes h b are located between the lines of pipe, by which means the pipes are subjected to heat on all sides.

Fig. 5 shows pipes consisting of two or more spiral layers, but connected with the jacket and the dome in the same manner as before described.

The operation is as follows: The water is admitted through nozzle 7.-., and, passing through the hollow dome above the cap D, it enters thc pipes at l[and passes into the jacket G. 1t circulates throughout the jacket and becomes highly heated. From the jacket the water passes through r17 into the coils of pipe and circulates up and down till finally it passes out ot the pipes into the hollow.

space under the cap l), and thence it escapes through discharge-pipe E, as before described. The action is effective, as the water is subjected to great heat during its- IOO air and gas pipes entering the said oompartnlents, the hollow dome having an inlet at its top and provided with a covering-cap inside the hollow annular jacket between the base and dome, the induction Water-pipes leading from the dometo the top of the jacket, the circulating Water-pipes leading from the bottom of the jacket to the dome under1 the covering-cap, and the central dis- Io charge-pipe leading from the covering-cap down through the heater, as herein shown -and described.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.'

JOHN BOMA.
