HOMER ANDERSON, OF PEEKSKILL, NEW YORK.

WATER-HEATER.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed May 2. 1903- Serial l-lo. 155.254-

T 0 all whom it may concern:

Be it known that I, HOMER ANDERSON, a citizen of the United States, residing at Peekskill, in the county of Nestchester and State of New York, have invented a new and useful Water-Heater, of which the following is a specification.

This invention relates to means for heating water, whether by gas or fluid flame or hard fuel. Its object is to reach a high efficiency with a small number of parts in the heater. The water section shown in the drawings is not new to this application, as it forms the subject matter of a patent issued to me Nov. 25, 1902, No. 714,357.

The objects are attained by the means set forth in the accompanying drawings, in which Figure I is a vertical cross-section of a gas water heater. Fig. II illustrates the outward appearance of the heater, and the part in section shows a cross-pipe connection.

Fig. III is a top view of a water jacket. Fig. IV is a bottom view of a water jacket. Fig. V shows a plan of the burner plate. Fig. VI

is a detail relating to the burner plate.

The heater consists of a burner plate p which is fastened to a water pipe 8, and sustains several parts of the heater. The base .6 rests upon it, inclosing it peripherally within its lower edge. The top of the base has an inwardly projecting flange 10 with a drooping inner edge a and a rim 11. Within the rim 11, and resting on the flange 10 is a water-jacket e. The water-jacket is a double cylindrical vessel with a top, but the bottoms of the cylinders are joined, an annular water chamber 3 being formed between the plates 1 and 2, and a horizontal water chamber 3 at the top. A hole is provided in the top for a water pipe 8.

Within the water-jacket is a casing c, 0,

extending to the rim 8 on the burner plate.

There is thus formed a passage 4 between the casing and the inside of the water-jacket.

Within the casing are the heater sections, what kind is not material, but those herein shown have a very high efficiency.

Beneath the sections, resting on the burner plate, is a gas burner 7. Any good burner may be used; but preferably one that would be adapted to direct its flames in line with the tubes of the sections a.

The base b is provided with a pipe flue 6, for connection with a chimney. In some situations a draft will be needed to produce perfect combustion with this combination, as well as to carry off the products of combustion and uncondensed vapors.

The several parts being mounted together as shown, it will be seen. that the casing 0 divides the space within the water-jacket and the base in two parts, i. e. that occupied by the sections a and the burner, and the passage 4 and the chamber 5 in the base. Air for combustion enters through holes in the burner plate in the line of the arrows 0, 0. The products of combustion move in the direction of the arrows m to the top of the casing, down the passage 4, into the chamber 5, and therefrom through the outlet 6, as indicated by the arrow m.

The water flowing through the heater enters the top of the water-jacket at the pipe 12, flowing in the directions of the arrows a,

downward in the jacket, out of the jacket through the-pipe 9, into the pipe 8, upwards through the sections, and out at the pipe 8, as indicated by the arrow 17/.

The water enters the water-jacket cold and gradually warms as it flows out at the bottom. WVith a gravity connection it would not flow out at all except that what is in the sections rises to so many degrees in excess of that in the jacket, that it naturally rises from the sections and draws the water from the jacket.

As the products of combustion make contact with the cold surfaces of the water jacket considerable condensation takes place, and the water formed trickles down the inner side of the acket. To prevent its being an annoyance, the base and burner-plate are adapted to receive and dispose of the triokling water. The object of the downward inclined flange a is to prevent drops from adhering to and running down the inside surface of the base. The drops will fall from the flange to-the plate below.

The burner plate is made to incline from its center towards the casing rim 3, and from the base inwardly towards said rim. Any moisture dropping from the sections or the inside of the casing 0 will gravitate towards the rim. That which falls fromthe jacket and outside of the casing will also run towards said rim, a gutter being constituted on each side of the rim. To drain the two gutters a hole from one to the other (15 and 16), unite in an outlet 17 to which a pipe may be attached to carry off the water. To prevent water dripping out of the air inlet holes 0, 0,

and around the pipe 9, flanges 20 and 21 respectively are turned around them as shown in Figs. 2, 5 and 6.

The connection between the water-jacket and the sections is represented as being made with pipes extending below the burner plate. Two or more cross connections may be made if desirable, the water-jacket shown in Fig. 4 being adapted for two connections, at 9, 9.

When the Water jacket is made with a very narrow water space and it is desirable to make the pipe connection at the end of the jacket as in Fig. II, provision for a large pipe connection may be made as at 9, Fig. III, in which the inner acket surface is expanded to make room for the pipe connection.

To give more heating surface to the waterjacket the inner cylinder may be corrugated, as shown in Fig. IV. The water-jacket may be made of sheet metal or it may be cast.

I claim: A

1. The combination in a water heater of an annular water-jacket, a basewith a flue outlet, a casing dividing the space within the water-jacket and the base in two compartments, water sections within the casing, a heating medium at the base of and within the casing, and a water connection between the water jacket and the sections.

2. The combination substantially as shown of a burner plate adapted to concentrate the drip of condensation, a rim on said plate for the attachment of a flue casing, the plate having perforations within the said rim, a base resting on said plate provided with an outlet and a flange to receive a water jacket, an inverted cup-shaped annular water jacket on said flange, the water jacket provided with a hole in the top for the passage of a water pipe, a flue casing within the water jacket resting on the burner plate, a burner at the bottom of the flue casing, water sections within the flue casing, a pipe connection between the water acket and the water sections, and a pipe connection in the water jacket.

3. In a water heater the combination of heating sections united together one above the other, a base to support a burner under the sections, a burner on said base, the base provided with a circulating passage and a pipe outlet, an annular water jacket .on the top rim of the base, the water jacket having a chamber at the top with an opening through it for a pipe, a casing between the sections and the water jacket, and the water jacket having a connection with the heating sections.

4. In a water heater the combination of heating sections united together one above the other, a burner under the sections, an annular cup-like water jacket with an open ing in the top inverted over said sections, a cold water supply to the jacket, a connection from the jacket below and through the burner to the heating sections, and an outflow pipe from the top section.

5. In a water heater the combination of heating sections superposed one upon the other, a burner under the sections, an annular cup-like water jacket inverted over and inclosing the sections, the water jacket provided with an opening in the top for an outlet pipe from the sections, a cold water supply entering the water jacket, the water jacket connected with the sections by means of a pipe extending from the water jacket below and up through the burner to the lower section, and an outflow pipe from the top section through the opening in the water acket.

6.
