JOHN F. WILLIAMS, OI SANDUSKY, OI'IIO.

COMBINED .ASH-PAN AND BURNER.

To all whom it may concern.'

Be it known that I, JOHN F. VILLIAMs, a citizen of the United States, residing at Sandusky, in the county of Erie and VState of Ohio, have invented a certain new and useful Improvement in Combined Ash-Pans and Burners, of which the following is a full, cleai', and exact description, reference being had te the accompanying drawings.

This invention relates to a combined ash pan and gas burner, and more particularly to an ash pan and burner which may be employed in connection with stoves adapted to burn both solid and gaseous fuel.

hiere limitedly, the invention consists of a combined burner and ash pan which may be conveniently inserted into and i'emoved from its place in the ash pit lwithout disturbing the arrangement or constructieii of the associated parts; the invention also consists of the cooperating features of the buriiei' and of the stove and gas supply ducts which will enable my device to subserve its double purpose as a burnei' and ash pan, retaining the advantageous features of both the pan and the burnei' without sacrificing the efficiency of either.

Generally speaking, the invention may be defined as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated iii the drawings foriniiig a pai't hei'eof, wherein- Figure 1 represents a vertical sectional View through the lower part of a stove having my invention applied thereto; Fig. 2 i'epresents a sectional detail of the combined ash pan and burner, with the central burner in inoperative condition; Fig. 3 represents a bottom plan view of the combined ash pan and burner; and Fig. 4 a sectional view taken at right angles to Figs. 1 and 2.

Describing the pai'ts by reference characters, 1 represents the lower portion of a stove adapted for the burning of solid fuel, as coal, and provided with a grate 2 of ordinary construction. 3 denotes the ash pit of the stove, which may be also of ordinary construction, having downwardly flaring sides and provided with a door 4 at the fi'ont thereof and with an opening 5 provided with a closui'e 6 of mica or similar transparent material, permitting inspection of the interior of the ash pit and of the burnei' therein. 'lhe bottom of the ash pit is provided with a plate 7 constituting a closui'e therefor, said plate having a plane upper surface except as Specification of Letters Patent.

to the central portion thereof, where it is pi'ovided with a depressed portion S forming with its vertical side wall a downwardly-pi'ojecting chamber. The chamber formed by the depi'ession is provided with an upwardly projecting nipple 9 extending nearly to the level of the upper surface of plate 7 and also with a downwardly projecting nipple 10 which is provided with an external thread for the reception of a mixer 11. The nipples 9 and 10 may be conveniently cast with the plate S and together form a passageway 12 communicating with the mixer.

On top of plate 7 there is mounted my combined ash pan and burner 13. The uppei' portion of the combined ash pan and burner is of oi'diiiary construction, havingI upwardly flared side walls, the upper perimeter of which is ef sufficient extent to receive the ashes discharged from the grate 'lhe bottom of the ash pan is formed mainly by a burner 14, shown as annular in shape, the outer portion of said burner being provided with an upwardly projecting ilange 1 5 within which the lowei' edge of the pan 13 lits, such pan resting on an outwardly projecting flange 16 formed with the burner. The ash pan 13 may be secured to the vflange 15, as by means of rivets 17.

The burner1ll, as previously stated, is of the annular type, having a peripheral inlet connection 1S projecting therefrom adapted to receive the nipple 19 of a gas-and-air inlet projecting through the lower end of the ash pit, opposite the door 4, said gas-and-air inlet communicating with a mixer 2() located outside and preferably at the rear of the stove. The inlet connection 1S is flared at its outer end to insure its receiving the end of the nipple 19 in sliding the pan and bui'nei' into place in the stove. 21 denotes a gassuppl)r pipe having a valve-controlled branch 22 connnunicating with the mixer 11 and a second valve-controlled branch 23 communicating with the mixer 20. The gas-andair inlet which projects through the rear wall of the ash pit has threaded thereon a nut 2-1- which serves as a stop for the combined ash pan and burnei' and enables the saine to be properly positioned both with reference to the ash pit and with reference to the gas-andair inlet when being inserted into the ash pit.

The burner' 14 comprises, in addition to the flanges 15 and 16 and the connection 1S, the gas-and-aii' distributing chamber 25. This distributing chamber is provided in its outer periphery with the burner orifices 26, said burner orifices being located below a downwardly extending flange 27 projecting preferably from the iiange 16. At its central portion, the burner 14 is provided witha recess 28, the bottom of which is substantially flush with the bottom of the chamber 25. The plate forming the bottom of the recess 28 is provided with a nipple 29 projecting upwardly froma central aperture 30, said aperture registering with the bore 1 2 of nipples 9 and 10. Nipple 29 extends upwardly substantially as far as the upper surface of the burner 14 and forms part of a central burner which may be employed for the purpose of igniting fuel carried by the grate 2 for the purpose of starting the fire in the stove or for heating in moderate weather.

1t will be observed that the central portion or depression of burner 14 is smaller in area than the chamber formed within the central depression of the bottom plate 7. As will appear by reference to the drawings, the burner 14 rests on the bottom plate or ridges 31 and is provided beneath its lower surface with passageways 31 which project radially from the central portion of the burner to the outer periphery thereof and form fuel passages whereby gas and air discharged into the central recess through the plate 8 may be discharged at the outer periphery of burner 14 and be ignited there beneath the flange 27. /Vhen employed in this manner, thevalve 32 will ordinarily be closed and the valve 33 opened and the upper end of nipple 29 will be closed by a cap 34 as well as by a plate 35 adapted to rest upon a ledge 36 at the bottom of nipple 29. However, the mixer 11 and the nipples thereabove and the passageways 31a provide means for supplying air to the grate and to the flames issuing from the burner orifices 26 when the valve in the branch supply 22 is closed.

N hen it is desired to use a central burner for the purpose of kindling a i'ire on the grate 2 or for heating, as in moderate weather, the cap 34 and plate 35 are removed and a burner superstructure is applied to the nipple 29. This burner superstructure comprises a burner tube 37, the lower end whereof is adapted to lit more or less closely the exterior of nipple 29. The lower portion of the burner tube is preferably enlarged, as shown at 38, to receive the nipple 29, and such enlargement is provided between the top and bottom thereof with an inwardly projecting rib or liange 39 adapted to clamp a screen 40 between itself and the top of said nipple. The contracted portion 37 of the burner tube is provided with a spiral rib 41 extending therearound for the purpose of thoroughly intermingling the gas and air flowing therethrough as well as assisting inpreventing the flashing back of the flame within the burner tube. The burner tube is providedV eeassi at its upper end with a spreader plate 43 be-' neath which the mixture of gas and air is discharged through one or more slots 44. A set screw 38a clamps the burner tube to the nipple 29 and enables the pan to be emptied without disarranging the burner parts. K

TWith the apparatus constructed as described, the operation will be as follows Then it is desired to use my device simply as an ash pan, it will be in the form shown in Fig. 2, with the central burner out of commission and with the central opening closed by the plate 35 and cap 34. In this condition, it will operate as an ordinary ash pan to receive the ashes discharged from the grate and prevent the same from dropping through the central portion of the ash pan and may be conveniently removed through the stove door 4 and its contents emptied in the usual manner. In reinserting the device in the stove, care need be taken only to see that the connection 18 receives the nipple 19, the nut 24 having been so adjusted as to secure the proper relation between the top of the ash pan and the grate. 1f it is desired to use my device as a burner for the purpose of heating a stove, either alone or in conjunction with solid fuel, it is only necessary to open the valve 32 and ignite the gas at the orifices 26 which are nearest the door 4. The flange 27, which overhangs the orifices 26, insures the ignition of the gas at all the orices of burner 14 and protects said orifices from any ashes that may drop from the grate and fail to enter the pan. 1f desired to augment the heat thus supplied, or to employ a smaller amount of heat, as the case may be, the valve will be opened and gas will then flow through the radial passageways 31EL and may be ignited beneath. the flange 27, either by the gas burning at orifices 26 or, in case gas is not being supplied through said. orifices, by the application of a match or taper beneath the flange 27. 1f desired to use the central burner, as for the purpose of lighting the solid fuel on the grate 2, it will be necessary only to remove plate 35 and cap 34 and apply to the nipple 29 the burner superstructure shown in 1. The mixture of gas and air from the mixer 11 will then pass upwardly and be burned at the slot 44 beneath the grate. As a convenient means for insuring a proper relation between the burner connection 18 and the nipple 19 when the combined burner and pan is inserted in place, the bottom of the pan and burner is provided with short lugs 45 adapted to enter longitudinal slots 46 in the plate 7.

The construction above described, while possessing great advantages in connection with the ordinary types of heating stoves, is simple and economical of production and may be applied to existing types of stoves with a minimum of alteration.v

While 1 have shown a circular ash pan and a main burner of corresponding shape, the shape shown is for the purpose of illustration only. The upwardly flaring sides of the ash pan protect the burner orifices 26 from any ashes that may fall into the ash pit, and this shape of pan, combined with the location of the main burner orifices and the shape of the ash pit, constitute a very efficient construction for heating the lower portion of the stove.

Having thus described my invention, what I claim is:
