WATER-HEATER FOR STGVES, RANGES, @nC.

EHECIPICATION forming part of Letters Patent No. 388,927, dated December 9, 188%.

Application filed March 17, 1584. (No model.) i

To (tZZ 10710772, it may concern:

Be it known that I, JOHN A. Paton, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in \VaterlIea-ters for Stoves, Ranges, &c.; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters ofv reference marked thereon.

My invention has for its object to provide for use in connection with stoves, ranges, 1550., a water-heater which is capable of being applied or detached without putting out or at all disturbing the tire in the fire-pot or lirechainber.

The nature of my invention will be best apprehended from the following description, taken in connection with the accompanying drawings, and the particular features of novelty will be pointed out in the clauses of claims at the end of the said description.

The drawings referred to show in Figure 1 a sectional view of the fire-chamber ofa range with my improved water-heater applied thereto. Fig. 3 shows in perspective theinnerside or face of the open or slotted wall of the lirechamber. Fig. 2 shows the rear side of said fire-chamber wall. with the heating-pipe in position, the outer plate or cap being removed; and Fig. 4 is an end view of the stove, showing the outer plate or cap and the damper for covering the aininlet thereof.

Similar letters of reference in the several figures indicate the same parts.

The letter A indicates the wall of the firechamber through which the heater is applied. This wall is preferably formed of a single casting, and is formed with a series of partitions or fingers, a, supported at one end only, as shown, and so arranged as to leave a sinuous interval or open space, 12 I) b 1), extending uninterruptedly from top to bottom of the wall, as clearly shown in Fi Each of the fingers or partitions a is constructed of wedge-shape form in crosssection, being widest at the inner side next the lire and narrowest at the back. The wide front face of each of the fingers or partitions is also preferably beveled backward from bottom to top, as shown at c (I. The wall thus constructed is secured appropriately at one side of the firechaniber, and constitutes the permanent wall thereof.

The water-heater proper consists, preferably, ofa sinuously-bcnt pipe, D, adapted to fit into the correspondinglyshaped interval or space b b b b in the wall A without entirely filling said space, though nearly so, and having its lower and upper ends formed so as to be coupled to an induction-pipe, E, and an eduction-pipe, F, respectively. The fingers or partitions a project rearwardly, and when the heater-pipe is placed in position it rests within the fingers, as shown in Fig. 1. A back plate or cap, G, covers completely the projecting fingers or partitions as well as the heater-pipe, upper and lower openings, 9 9, being provided for the outlet and inlet ends of the heater-pipe, as shown. This outer plate or cap is secured in any suitable manner, and can be applied and removed at pleasure". It is preferably lined with a lining composed of a backing of fire-clay, h, and a facing of asbestus, '5, for the purpose of preventing any escape of heat by radiation.

.Vhen the heater-pipe is placed in position, its inner surface comes in direct contact with the fire in the fire-chamber, and the wedge shape of the fingers or partitions enables the circulation of heat entirely around its rear, the amount of heating-surface exposed being sufiicient to cause a very rapid heating ofthe water circi'llating through the pipe. The front face of the fingers or partitions need not necessarily be backwardly beveled, as shown; but I prefer that construction, for the reason that it assists largely in increasing the amount ofpipc-surfacc exposed to the direct heat of the fire.

W hen for any reason it is desired to remove the heating-pipe, the result can be easily and quickly accomplished by first disconnecting the induction and eduction pipes, then taking oft the outer plate or cap, and then finallyremoving bodily the heater-pipe. The removal. of the heater-pipe in no way affects the contentsof the firechamber, for whether or not the heaterape is in position the fingers or partitions a of the wall constitute the effective lateral support to the fuel in the fire-chamber.

In stoves and ranges as ordinarily constructed the water-heater or water-back is a fixture and incapable of removal or of replacement without withdrawing the fire from the fire-box; but in my invention, as has been seen, the application or removal of the water-heater can be effected at any time without trouble or inconvenience, or without disturbing the fire at all. This-capability of ready removal is important,as it enables the water-heater to be withdrawn when from any reason the watersupply fails and it is desired to prevent the empty water-heater from being subjected to the action of the fire.

It is obvious that the water-heater pipe may be constructed in different shapes and applied to differently-formed walls, and I desire to be understood as covering all such obvious modifications, the essential feature of my invention consisting in applying to an open sided or slotted fire-wall a heater which shall fill or nearly fill the openings or slots in the wall, and be capable of application and removal at pleasure.

Provision is made for cooling somewhat the water-heatin g pipe, when desirable, without re moving said pipe from the stove or range, by the employment of a damper, 7, arranged on the end or side or top of the outer plate or cap G, and adapted to cover or uncover at pleas.

ure a series of openings in said plate or cap. When the damper is moved so as to uncover the openings, cold air is admitted within the cap and the temperature of the water-heating pipe is thereby reduced. To exclude the cold external air the damper, is moved in the opposite direction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The firechamber of a stove or range having a slotted wall adapted to normally support the fire, and a water-heater adapted to be ex posed to the fire through the slots or openings in the said wall, substantially as described.

2. The combination, with a fire-chamber Shaving a slotted wall,of a water-heater adapted, when inserted, to be exposed to the fire through the slotsin the wal1,and to be applied and removed at pleasure without disturbing the contents of the fire-chamber.

3. The combination, with the fire-chamber having a slotted wall, of a water-heater exposed to the fire through theslots in the wall, and a back plateor cap inclosing the waterheater, so as to effect a circulation of heat behind and around the heater, substantially as described.

4. In the herein-described water-heater,the combination of the wall having the fingers or partitions with the space between them, and the heater-pipe adapted to fit the space between the fingers, substantially as described.

5. The combination of the wall having the fingers or partitions of wedge-shaped crosssection, with the water-heater pipe.

6. .The combination, with the wall having the fingers or partitions of wedge-shape cross-sec tion, of the water-heater pipe adapted to fit between the fingers, and the back plate or cap for inclosing the pipe and fingers, substantially as described.

7. The combination of the wall having the fingers or partitions made bevel'ing on their faces next the fire,'with the water-heater pipe, substantially as described.

8. The combination, with the wall having the fingers or partitions of wedge shape in cross-section, and having the inclined front faees,of the water-heater pipe arranged in the space between the fingers, substantially as described.

9. The combination of the wall having the fingers or partitions of wedge shape in crosssection provided with the inclined faces, with the water-pipe arranged in'the space between the fingers and with the back plate or cap,the whole constructed and arranged substantially as described.

10. The combination, with the fire-chamber having the slotted wall, of a water-heater adapted,when inserted, to be exposed to the fire through the slots in the wall, anda back plate or cap inclosing the water-heater, and having openings closed by a damper, substantially as described.
