HENRY TRENKAMP, OF CLEVELAND, OHIO.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 470,224, dated March 8, 1892.

Application filed December lI 1890. Serial No. 373,144. (Nomodel.)

To a/ZZ whom t may concern.-

Be it known that I, HENRY TRENKAMP, a citizen of the United States, residing at Cleveland,in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in VVater-Heaters for Vapor or Gas Stoves; and l'do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates t0 improvements in water-heaters; and it consists in an attachment especially adapted to vapor or gas stoves, the same comprising a device for heating water circulated through the same and arranged between the burner-tubes and the -openings for vessels on the top of the heater, so that water may be heated while the heat used for that purpose may also be utilized, as in other stoves, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of the rear end of a stove to which the attachment comprising the invention is fixed, as-shown in full lines. Eig. 2 is a rear elevation of Fig. l with the curved back plate removed and the top part in section, so as to show the relation of thel heating-tubes, the water-heater, and the openings in the top of the stove. Fig. 3 is a plan view of Fig. l with the covers to the openings of the top removed, so as to fully disclose the water-heater beneath. Fig. 4 is a cross-section taken on line x, Fig.

A represents the back part of a well-known form of vapor or gas stove and provided with tube B for the distribution of vapor or gas to the burners-that is to say, either vapor produced from gasoline or the like may be used and conveyed through tube C from a generator, or natural gas or illuminating-gas The vapor or gas flows through the tube B into the two parallel tubes C, which constitute the burner-tubes for this attachment and are provided along their top with a series of small diagonal perforations c, through which the gas issues and burns.

D represents the attachment casing or frame, secured, as shown, to the back of the stove by any suitable means, and provided with one or more openings d in its top adapted to receive vessels for cooking, the same as on an ordinary stove.

E represents the water-heating device, corresponding in one sense with the water-back found in cooking-stoves and ranges and serving a kindred purpose. This heater is novel in both construction and arrangement, it being formed, in a solid piece of casting consisting, preferably, of brass, although copper or other metal may be used for this purpose, and has its water-channel cored therein, so as to aord a free and open circulation for the water. This device is arranged horizontally toward the top of chamber D and is formed of four or more parallel tubes e, connected at their opposite ends alternately by the short tubes e', or suitable curved returns, so that, supposing the fluid to enter the rst or rear pipe at e2, the water will ow thence to the opposite end of said tube, across through the connecting-tube c', and thence back through the next tube e, and so on around until it issues out of the heater at e3, whence it is carried to the reservoir or boiler or other place where desired for storage or use. The four or more parallel tubes c are arranged, practically, in pairs of two or more upon either side of the center, and the pairs are shown here as connected by a web e4. An open-draft passage e5 is provided between the two sets of tubes. Upon either side of the air-passage e5 on the two inner tubes and on the outer side of the two outer tubes are parallel vertically-inclined flanges e6, partaking somewhat of the curvature of the respective tubes and extending upward therefrom a slight distance, so Ythat the flame which strikes these tubes will have a tendency to roll around the same and be dil IOO allow sutiicient` exposure` to the dame.

Combustion is supported through the airopenings g in the bottom of the` attachment chamber, and openings h, front and rear, at the top ofthe chamber afford outlets for the products of combustion, so that a steady draft is afforded up through the attachment chamber and combustion is made complete. The bottom of the attachment D might be entirely open; but a perforated plate at this point is preferable. It will be noticed that the cored Water-heater is arranged horizontally, with the burner-tubes beneath the same in such relation that the flame strikes the tubes diagonally along their bottom.

The attachment D, which contains the water-heater, and the tubes C are shown here as connected with a vapor or gas` stove; but it will be understood that this. attachment is not necessarily so connected and that it` may be used separately fro m the stove, if preferred. Each of the tubes C has` its openings c arranged in parallel rows at an outward angle to each other, so that while` each tube occupies a central position with respect to two of the parallel heater-tubes the jets of iiame will issue diagonally therefrom against the bottom of each heater-tube, from which pointi the flame rolls round in unbroken volume over the side ofthe heater. Thewebse4 serve as diaphragms between the allied pairs of tubes e, and are located centrally thereof, so

that whletheyserve to connect `the saidtubes and to close the space between them they also this means; at least thirty gallons of water can-` be heated per hour, while a` full flame of heat ismaintained` for thel cooking-openings on` the top of the attachment-chamber.

Having th us@ described my invention, what ltorated burner-tube arranged beneath each pair of water tubes, substantially as described.

3. The water-heating attachment herein described, consisting of parallel water-tubes having open` communication. one to the other to` establish circulation, the said tubes connected in pairs, and the twoadjacent tubes of opposite pairs provided along their top inner portion with longitudinal tianges on either side of the draft-space between said tubes, in

`combination with the burners beneath said tubes, substantially as described.

4. In a water-heater, a pair of parallel water-tubes e, connected at one end by a crosstube e, a burner-tube below said tubes provided with two rowsof jet-orifices arranged so that the dames therefrom will be directed diagonally against the bottom and toward the ou ter opposite sides of the water-tubes e, and` the flanges e6 on thesaid sides of tubes @,sub-

` Stantally as:` shown and described. By cation this. 21st day of November, 1890.

Witness my hand` to the foregoing speci- HENRY TRENKAlVIl?. VitneSseS:
