`SIPECIFICA'I'ION forming part of Letters Patent No. 471,82*?, dated March 29, 1892.

To a/ZZ whom it may concern.-

Be it known that I, THOMAS W. REES, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Supplementary Heaters for Range-Boilers, of which the following is a specification. A

One object of my invention is to provide the water-reservoir of an ordinary stove or range with an attachment whereby the heating of water can be effected by means of a gas or oil burner, a further object being to insure the proper circulation of the water through said heating attachment, and a still further object being to economically combine such attachment with the ordinary circulating-pipes of the reservoir and water-back.

These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a waterreservoir with heating attachment constructed in accordance with my invention, a portion of the range and range-setting being shown by dotted lines and the ordinary circulatingpipes of the reservoir and water-back being also illustrated; and Fig. 2 is an enlarged vertical section of my improved water-heating attachment with part of the shell or casing of the reservoir also shown.

In Fig. l, A represents part of a vertical water-reservoir, such as is ordinarily mounted adjacent to the setting of a kitchen stove or range, this reservoir communicating with the water-back in said stove or range through a cold-water pipe B and a hot-water pipe B the cold-water pipe entering the .bottom of the reservoir and the hot-water pipe communieating with the same some distance above said bottom. Instead of connecting the upper end of the hot-water pipe B directly with the reservoir, however, said pipe communicates with the reservoir through a T-coupling a, which also has a short pipe-section b, coupled by means of a duplex or right-and-left nut d to a pipe-section f, which is coupled by means of an elbow g to avertical pipe h, the lower end of which carries a heating-vessel D, which, in the present instance, is of substantially spherical form,althoughit may be of any desired shape without departing from the essential feature of the invention.

Extending from a point some distance above the bottom of the reservoirA into the heatingvessel D is a bent pipe F, considerably less in diameter than the pipes and fittings forming the before-described communication between said heating-vessel and the reservoir, this pipe serving to convey the cool water from the reservoir into the heating-vessel and discharging it close to the lower portion of said vessel, the water when heated rising through the pipe connections above described and entering the reservoir A some distance above the bottom of the same. The heating-vessel D has at one side a projecting stud t, which is connected by an elbow-coupling t" to a depending pipe k, and to the lower end of the latter is screwed a T-coupling m, carrying pipe-sections n n, one of these' sections having. at a point immediately below the heating-vessel D a burner of any desired character, that shown in the drawings consisting simply of an elbow-coupling p and short pipesection 1o. The other pipe n' carries an H- coupling s, into one end of which is screweda plug t, with nozzle t projecting into the coupling s. vided with a flexible tube fu, communicating with any adjacent gas-pipe, so that the gas escaping from the jet t causes an inflow of air through the open branches of the coupling s and the mixture of vair and gas is ignited at the burner pi and envelops or partially envelops the heating-vessel D, the heat being by preference retained by .means of an outer hood J, as shown in Fig. 2. When the reservoir A is emptied, the Water will also be withdrawn from the heating-vessel D down to the level of the bottom of the pipe Rowing to syphon action ,so-that the heating-chamber will not be injured by the freezing of water therein in cold weather when the heater is not in use-as, for instance, in an unocupied house.

It will be evident that in carrying out my invention an oil-lamp, gasoline-burner,y or equivalent device may take the place of Ythe gas-and-air burner which I have described, the latter, however, being preferred.

The outer end of this nozzle is pro-- IOO Having thus described my invention, I claim and desire to secure by Letters Patentl. The eornbination of the watenreservoir of a stove or range, With a heating-Vessel, :i pipe Connection between the upperportion of said Vessel and the reservoir, and a second pipe connection passing through the first and forming an inverted U, whereby it presents a depending portion both Within the reser- Voir and Within the heating-Vessel, substantiaily as specified.

2. The combination of `the stove or range, the external Water-reservoir, the circulatingpipes connecting said reservoir with the Water-back of the Stove or range, a, supplementary heating-Vessel, an oil or gas burner Ifor Said supplementaryY heating-Vessel, a pipe for conveying the heated Water from the vessel to the reservoir, in internal inverted-U pipe serving is a circulating-pipe sind having one depending portion Within the vessel and another Within the reservoir7 and a T-coupiing whereby both the hot-Water pipeof the Vessel and the upper circulating-pipe of the reservoir are coupled to the latter, substantially as specified.

3. The combination of the reservoir, the heating-Vessel and pipe Connection between the two, with a, gas oroil burner hung to :Lv
