SPECIFICATION fOl'ming part of Letters Patent No. 783,617, dated February 28, 1905.

Application filed October 27, 1904. Serial No. 230,190.

To rtZZ who/rt 116 Hm/y concern:

Be it kno wn that 1, (1i nose It Do a 10 LL Ooo er: a, a citizen of the United States of America, residing at St. Johns, in the county of Clinton and State of Michigan, have invented certain new and useful Improvements in Steam-(utenerators, of which the following is a specilication, reference being had therein to the accompan ying drawings;

This invention relates to new and useful improvements in steam-generators, and has particular reference to that class of generators used for heating houses.

To this end the invention consists in the novel construction of the generator involving the use of the fewest possible parts and of the water-jacketed lire-pot whereby the vertical water-wall may be directly supported upon the lire-pot in constant comn'iunication therewith to maintain a circulation of the water therein; and the invention consists, further, in the peculiar construction, arrangement, and emnbination of parts, all as more fully hereinafter described, and shown in the accompanying drawings, in which- Figure 1 is a vertical transverfi section through my improved generator and lire-pot; Fig. 2, a vertical central longitudinal section through the generator and lire-pot; Fig. 3, a plan view of the fire-pot detached.

A. is the lire-pot, provided with the annular water-spaee B and peripheral flange C, under the forward edge of which the transverse metal plate D projects, which entirely fills the space between the boiler-frrmt and lire-pot, said plate being let into the brick side walls at its opposite ends to :form a support for the lire-pot at its forward end.

E represents laterally-extending lugs integrally formed with the iire-pot near its rear end and adapted to be let into the brick side walls to support the lire-pot therefrom in conjunction with the plate 1.), which plate may, if desirml, be made integral with the lire-pot.

(i is a vertical water-wall adapted to be secured to the top of the lire-pot at its rear edge by screw-bolts ll, passing through apertured ears l on the watm-wall and lire-pot, respectively, the meeting faces of the lire-pot and water-wall being faced off to form a tight joint, communicating with each other through openings in the iirc-pot and water-wall, respeetlvely.

J represents stay-bolts connecting the front and rear water-walls.

K represents the water-tubes projecting from the front side of the water-wall, closed at their outer ends and threaded into openings in the water-wall at their inner ends, said tubes being preferably inclined slightly upwardly to cause the water to drain toward the water-mill.

L is the steam-drum, supported upon the vertical water-wall by screw-bolts M, passing through apertured ears N on the drum and wall, respectively, said drum communicating with the water-wall through the passage O.

P is the smoke-stacl It the boiler-front provided with the usual fire and ash-pit doors 5 and U is the grate supported within the lire-pot, so that the heat of the [ire will heat the walls of the lire-pot and water contained therein,thereby causing an upward circulation of the same, thus utilizing what would be waste heat to initially heat the water, which I find to be a great advantage and saving in this type of heaters.

By arranging the water-tubes in the form of an arch. a lire-chamber is formed giving ready access to the lire-pot which holds the lire, and by providing the lire-pot with a wator-jacket forming part of the circulating system it acts both to prevent the lire-pot from burning out and utilizing the waste heat to ing the circulation.

The water-wall and lire-pot being each intcgrally cast in one piece with the lateral lugs and the steanrdrmn in another piece, it forms a simple and cheap c mstruction with but two joints, which can be easily connected together by scre\vl )olts, thus making a heater which any ordinary steam-litter :an set up without the use of special tools.

Having thus fully described my invention, what .1 claim is 1. in a steam-generator, the (JOlHlJll'ltttlUll of l a lire-pot formed With an annular water-space heat the water therein, thus 'reatlv inereasand laterally-extending supporting-lugs, a water-wall supported on the rear end of the tirepot, a steam-d rum supported at one end by said wall and water-tubes closed at one end and communicating with the water-space of the wall at their opposite ends, said tubes being arranged to form an arch over the lire-pot.

2. In a steam-generator, the combination of a fire-pot formed with an annular water-space, a water-wall formed with apertured lugs at its opposite ends, apertured lugs on the lire-pot registering with the lugs on the lower end of the wall and bolts connecting said lugs,a steamdrum supported by said wall, bolts passing through lugs on the adjacent ends of said d rum and wall rigidly uniting said drum and wall, and water-tubes closed at one end and communicating with the water-space of the wall at their opposite ends.

3. In a steam-generator, the combination of a tire-pot integrally formed with an annular water-space and late rally-extending lugs forming the supporting means for the lire-pot, a

vertical water-wall supported on the lirepot,.

lugs formed with apertures on the lower end of the water-wall, bolts connecting said waterwall and lire-pot through said apertured lugs, a steam-drum wholly supported by said wall, apertured lugs on the drum and wall, bolts unitingsaid drum and wall through said apertured lugs, and water-tubes closed at one end and communicating with the water-space of the wall at their opposite ends, said tubes beingarranged to form an arch over the fire-pot.

4. In a steam-generator, the combination with the casing, of a fire-pot formed with an annular water-space and a peripheral flange around its upper edge, oppositely-disposed lugs on the tire-pot adapted to be let into the walls of the casing, a horizontal plate adapted to engage the peripheral flange to fill the space between the tire-pot and all and forming in conjunction with said lugs the means for supporting the lire-pot, a vertical waterwall supported on the lire-pot and communicating therewith, a steam-drum at the upper end of said wall and communicating therewith, and water-tubes closed at their outer ends and communicating with the water-wall at their inner ends.

5. In a steam-generator, the combination with the casing, of a lire-pot integrally formed with an annular water-space and a peripheral flange, oppositely-disposed lugs integrally formed with said flange and adapted to support the lire-pot, a plate engaging said flange and adapted to separate the tire-chamber from the ash-pit, a vertical water-wall communicating with the water-space of the lire-pot and supported thereon, means for securing the water-wall and lire-pot together, a cylii'idrical steam-d rum supported by said wall and watertubes communicating at their inner ends with the water-space of the wall, said tubes being closed at their outer ends.

6. In a steam-generator, the combination with the walls or casing, of a fire-pot formed with an annular water-space and a peripheral flange around its upper edge, oppositely-disposed lugs forming a continuation of said flange adapted to be let into the side walls to support the rear end of the ire-pot, aplate engaging said flange adapted to be let into the sidewalls to support the front end of the firepot and separate the fire-chamber from the ash-pit, a vertical water-wall supported on the lire-pot and communicating therewith, a horizontal cylindrical steam-drum communicating with and supported by said wall at its upper end and water-tubes closed at their outer ends communicating with the water-space of the wall at their inner ends.

7. In a steam-generator, the combination with the steam-drum,otthe vertical water-wall supporting said drum, a plurality ot' watertuhos communicating with the water-wall, said wall having openings in its lower portion and integrally formed with oppositely-disposed apertured cars, a tire-pot formed with a peripheral flange and an annular water-space having openings adapted to register with the openings in the water-wall, bolts passing through said ears and forming the means for uniting the water-wall and fire-pot, lugs on one end of the tire-pot and a plate adapted to engage the peripheral flange at the opposite end of the lire-pot to form the supporting means therefor.

8. In a steam-generator, the combination with the horizontal cylindrical steam-drum, ot' the vertical water-wall supporting said drum at one end and communicating therewith, said wall having openings in its lower end and provided with oppositely-extending apertured cars, a plurality of water-tubes closed at their outer ends and communicating with the water'- wall at their inner ends said tubes arranged in the form of an arch to form a tire-chamber extending the full length of said tubes, a firepot formed with an annular water-space having openings registering with the openings in the water-wall, bolts passing through said apertured ears for securing the water-wall and lire-pot together, and oppositely-disposed lugs on the tire-pot forming the supporting means for the fire-pot.
