ERNEST A. PETERSON, OF CHICAGO, ILLINOIS.

WATER-HE ATER.

To all whom it may concern:

Be it known that I, ERNEST A. PETERSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in VVater-Heaters and the Like, of which the following is a description.

My invention belongs to that class of devices known as heaters and particularly to that class known as circulating water heaters, and has for its objects the roduction of a sim le, cheap and efficient ieater of the kind escribed.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described and more particularly pointed out in the claims.

In the drawings wherein like reference characters indicate like or corresponding parts; Figure 1 is a vertical-partial sectional View of my preferred form of heater. Fig. 2 is a vertical partial sectional view of a slightly modified form; and Fig. 3 is a crosssectional view of the form shown in Fig. 1 taken substantially on line 33 of Fig. 1.

Referring to the drawings, the preferred construction comprises an inner shell 1 and an outer shell 2, spaced therefrom, provided with heads 3 and 4 forming a heating chamber surrounded by a water jacket. The head 3 is preferably extended as at 5 forming an inlet, and the head 4 similarly extended as at 7 to form an outlet. The inlet and outlet pipes 6 and 8 are shown.

plurality of water tubes 9 are provided and each arranged with its ends connecting the water jacket or chamber between the shells 1 and 2 with the body part extended into the heating chamber. As is shown the tubes 9 are preferably bent or twisted so that they substantially act as baffles and impede the passage of the heated gases through the heating chamber. The inner and outer shells 1 and 2 and the tubes 9 are preferably made of very thin material, the tubes being secured in position in any preferred or suitable way. The heads 3 and 4 may be secured on the shells 1 and 2 in any preferred or suitable manner.

Preferably in the lower end of the heating chamber is arranged some suitable form of burner as a gas burner similar to that shown. The burner shown comprises the body part 11 arranged to receive the illuminant from the supply pipe 12, 13 being a plate arranged Specification of Letters Patent.

Application filed September 30, 1907.

Patented June 22, 1909.

Serial No. 395,076.

in 1.1 with a space or opening 14 as shown. The late 13 may also be provided with a plura ity of apertures 15 therein,and a wire gauze 16 arranged below the plate to prevent back firing. The burner is supported at the lower end of the heating chamber with an air opening 17 as shown, in any suitable or preferred manner brackets 18 being shown for the purpose.

In the modified form shown in Fig. 2, a partition 22 is provided in the water jacket preferably in the upper part dividing the same into two parts. In this form the inlet is preferably arranged in the upper part of the water jacket near the artition so that the incoming fluid enters tl i e inlet from the pipe 6 and flows down and into the tubes 9 as indicated by the arrows, thence upwardly into the upper water acket and through the outlet into pipe 8. As is shown the partition 22 is preferably arranged with a space 23 so that the water in the lower jacket is not in contact with the partition touching the hot water in the upper water jacket, that is, there are substantially two partitions.

The usual form of storage tank may be used in combination with my device (not shown) if the same is desired, the heater creating a circulation through the storage tank whether water is being drawn from the storage tank or not, or whether the water is under pressure. It is obvious that in the form shown in Fig. 1 the water will circulate within the heater, without using a storage tank, that is, the parts may be so proportioned that a considerable quantity of water is stored within the heater itself circulating therein when the heat is applied.

As shown a baffle plate 19 or its equiva lent with suitable apertures therein may be placed in the upper part of the heating chamber to further impede the passage of the heat therethrough, and a flue pipe 21 arranged on the heater to conduct away the excess of heat and waste products of combustion.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the form, construction, and design shown without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, or design shown.

What I claim as new, and desire to secure by Letters Patent is:

1. A device of the kind described, comprising a heating chamber provided with a water jacket, a transverse partition dividing the water jacket into two parts with an inlet in one part and an outlet in the other, in combination with a plurality of water tubes, each tube having one end connected with one chamber in the water jacket and the other end with the other chamber with the gody part extended into the heating cham 2. A device of the kind described, comprising a heating chamber provided with a water jacket therefor, a transverse partition arranged in the upper part of said water jacket dividing the same into a plurality of parts with an inlet in one part and an outlet in the other, in combination with a plurality of water tubes each having one end connected to the lower chamber and the upper end connected to the up er chamber of said water jacket with the ody part extended into the heating chamber.

3. A device of the kind described, comprising a heating chamber provided with a water acket therefor, a transverse partition arranged in the upper part of said water jacket dividing the same into two arts with an inlet in one part and an out et in the other, in combination with a lurality of water tubes each having one end connected to the lower chamber and the other end connected to the uiper chamber of said water jacket with the ody part extended into the heating chamber.

4. A device of the kind described, comprising a heating chamber provided with a water jacket therefor a substantially two part transverse partition arranged in the upper part of sait water jacket dividing the same into two parts with an inlet in the lower part in proximity to said partition and an outlet in the other, in combination with a plurality of water tubes each having one end connected with the lower water jacket near one end thereof and the other end connected with the upper chamber, with the body part of said tubes extended into the heating chamber and arranged to substantially impede the heated gases passing through said chamber.

5. A device of the kind described, comprising a heating chamber provided with a water jacket therefor, a substantially two part transverse (partition arranged in the upper part of sai water jacket dividing the same into a plurality of parts, with an inlet in. the lower part in proximity to said artition and an outlet in the other, in com ination with a plurality of water tubes each having one end connected with the lower water jacket near the outer end thereof and the other end with the upper water jacket, with the body part extended into the heating chamber and arranged to baffle the heated. gases passing through said chamber, a baffle plate arranged in said heating chamber, a flue for conducting away the waste product of combustion, and a burner.

6. In a device of the kind described and in combination, an inner shell forming a heating chamber, an outer shell spaced therefrom and heads for said shells, said shells and heads forming a water jacket for said chamber, a transverse partition dividing the water jacket into two parts, one of said parts provided with an inlet and the other with an outlet, and a plurality of water tubes each having one end connected with one art of the water jacket and the other end with the other part with the body part extended into the heating chamber.
