Application ined June s, 1920.A serial No. 386,343.

T0 all 107mm t may concern:

Be it known that l, HENRY B. DALLIMORE, a citizen of the United States, and a resident of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and lmproved Gas-Heater, of which the following is a full, clear, and eX-' act description.

rFhis invention relates to improvements in gas heaters, and more particularly to a gas heater adapted to be positioned in the fire box of an ordinary coal range, an object of the invention being to provide a heater of the character stated which will function as a heater for the water back, as well as for the oven and stove ltop to permit the use of the range for all ordinary purposes dispensing with the necessity for using coal.

A further object is to provide a device of the character stated which can be quickly and easily assembled in a fire boX, which dis penses with the use of bolts and nuts to connect the parts, and which can be readily taken apart, and damaged parts replaced with but relatively small expense.

With these and other objects in view, the' invention consists in certain novel features of yconstruction and combinationsl and arrangements of parts as will be more fully hereinafter described and pointed out in the claims s In the accompanying drawings Figure 1 is a view mainly in elevation but partly in section illustrating my improved heater in the fire box of a coal range.

Fig. 2 is a view in section on the line 2 2 of Fig. 5. f

Fig. 3 is a fragmentary perspective view showing the manner of connecting the burner box to a standard.

Fig. t is a fragmentary sectional perspectiveview illustrating the distributing screen and adjacent parts.

Fig. 5 is a view in front elevation of the burner partly in section.

Fig. 6 is a top plan view of Fig. 5.

Fig. 7 is a fragmentary sectional perspective view illustrating a damper attachment fol1 the burner box. y

1 represents an ordinary coal range, having a Afire box 2, the latter provided with a water back 3 connected by water circulating pipes l and 5 with a water tank or domestic boiler 6. f

ln positionincr my improved heater AV in the fire bor. .2, fdispense with the ordinary grate of the range, and support the standards 7 of the heater directlyon the bottoni of the ash pit 8. y

The heater A is made'with a pair of relatively wiole open-work cast metal standards 7 supporting a top casting and a burner box 10 below the same. The top casting 9 is made with depending slotted lugs 11 receiving wedges 12, the latter projected through the standards 7 and effectually securing the parts together.

The box 10 is made at its ends with slotted lugs 13 which are projected through suitable slots 14 in the standards and vsecured by means of wedges 15. i

A coupling block 16 is secured to one standard 7 by means of a wedge 17 which is projected through a slotted lug 18 on the block, said lug being positioned through a slot 19 in the standard.

The block 16 is made with ar gas passage 2O which is supplied with gas by a nipple 21, the latter projected through an opening 22 in the front of the lire box. This opening is ordinarily provided to accommodate the shaking shaft or trunnion of the grate.

The top casting 9 is formedat its ends with relatively` large gas burners'23, having' removable perforated burner plates 24:, the latter preferably located under the stove holes 25, so that a cooking utensil can be convenientlylocated over the same.

Gas pipes 26 and 27 connect the two burners respectively with the gas passage 2O and have cocks 28 and 29 respectively therein to control the flow of the gas to the burners.

The burner boX 10 has an inlet nipple 30 inits bottom connected bya pipe 31 with the gas passage 2O and having a cock 32 therein. Y

This burner boX 10 is made with a forwardly extruded chamber 33 at its lower end having burner nozzles 34 in its top and other burner nozzles 35 are provided in the upright wall of the box. The nozzles 34' and 35. direct the flame and the heat toward the water back 3 to rapidly heat the same and thedraft over` the top of the vbox is .controlled by a hinged plate 36.v This plate may be given the desired angular disposition according to the shape of the waterback and its draft desired and I have` illustrated in Figs. 1 and 2, two different posi tions of this plate.

A convenient manner of securing the platek at its angle of adjustment is to provide a i slotted curved arm 37 on the plate and clamp the saine to one of the standards 7 by means of a bolt and wing nut 38.

The box 1G is preferably made with aref movable back plate 39 secured by screws4), so that the box and nozzles can be eilectually cleaned out as occasion may require.

Asemi-cylindrical screen 41 constituting a gas distributor, is located over the nipple 30 in chamber-33, and operates to distribute the gas throughout the box, preventing an over supply at any one set of nozzles, and a partition strip 42 is secured above the screen and cooperates with the screen in the performance of its functions.

l have illustrated in Fig. 7 a damper or draft controlling means which can be attached to the burner box and control the flow of air or inlet of draft between the box 1() and the water back 3. This draft control comprises a plate 43 which is secured to the outer face of the chamber 33 and which extends up to the bottom of the water back 3. A slide damper 44 iswmounted on the plate 43 and this damper 44 and plate 43 have registering openings 45 to permit the `air to pass through them and over the ltop of the chamber A partitionplate 46 is secured to plate 43, projects at right angles thereto and is positioned above the openings 45 so that this plate 45 acts as a deflector to compel the air te pass laterally as far as de! sired to `give the necessary oxygen supply to the several nozzles of the burner box to aid combustion.

1t will be noted particularly by reference to Fig. 7 that the burner nozzles 34 on top of the chamber 33 heat the bottom of the water back 3 and hence, these burners give efficient results to quickly heat the water. p

t will thus be noted that 1 provide a heater which can be placed inthe lire box of a coal range to heat the water baclr and supply all necessary heat for cooking purposes.

lhe device can be easily and quickly in` stalled and the pipes and coupling block can be positioned at either end or either side of the device in accordance with the location of the fire box, whether it be at the right or left hand end of the range, as the parts are made easily changeable or reversible.

Various slight changes might be made in the general forniand arrangement of the parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

1 claim z- 1. The combination with a range having awater back in its fire box, of a glas heater in the fire box, burner nozzles oi'i'onc side of the heater, and a hinged plate carried by the heater and constructed to control the heat to direct the saine against the water back.
