ADAM CLARKE, OF CHICAGO, ILLINOIS.

ODORLESS AND HUMIDITY-SUPPLYING HEATING-STOVE.

Application filed April 30, 1917.

To all whom it may concern:

Be it known that I, ADAM CLARKE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Odorless and Humidity-Supplying Heating-Stoves, of which the following is a specification.

This ii'ivention relates to improvements in heating stoves or apparatus, for dwelling houses or other structures, of the class in which gas is used as fuel and in which the air heated by its passage through tubes exposed to the heat of the burner and through a heating drum surrounding the same, and itconsists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

While the invention relates particularly to heating stoves or furnaces, in contradistinction to stoves and ranges used for cooking purposes, and is so shown in the drawings and. will be so referred to hereinafter, yet it will be understood that it is applicable for use in connection with ranges and cook ing-stovcs, and that numerous modifications and variations may be made therein without departing from the spirit of the invention.

The principal object of the invention is to provide a stove which shall be extremely simple and inexpensive in construction, strong, durable and efficient in operation, with its parts so constructed, arranged and operating as to afford means for the economical consumption of fuel, so as to furnish from the fuel and stove a maximum amount of heat, without the usual sensible dryness or lack of moisture, incident to the heat produced by gas-stoves of the type heretofore commonly in use, and without the emanation and distribution of the usual noxious, poisonous and disagreeable odors, soot and dust, or in other words, to provide a stove, which by reason of the novel construction, arrangement and operation of its parts, will prevent deleterious odors, fumes or products of combustion from the fuel escaping into the room and commingling with the air to be breathed, and will conserve the moisture in the air, or supply moisture thereto as it is heated.

Other objects and advantages of the in- Specification of Letters Patent.

vention, will be disclosed in the subjoined description and explanation.

In the accompanying drawings, which serve to illustrate an embodiment of the invention,

Figure 1, is a view in vertical section of the heater taken on line 11 of Fig. 2, look lug in the direction indicated by the arrows, and

Fig. 2, is a plan sectional view taken on line 22 of Fig. 1.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawings.

The reference numeral 7 designates the hollow base of the stove, which may be made of any suitable size, form and material, but by preference, of metal and rectangular or box-like in form, as shown. The base 7 is used for the purpose of holding water and for the support of other parts of the stove and has hinged thereto at one of its ends a lid or cover 8 which may be provided. at its end opposite the hinges 9 with a hasp 10 to engage a suitable catch 11 on the upper portion of the case or receptacle '7, which hasp and catch are used for holding the cover 8 in its closed position.

As shown in Fig. 1 of the drawings the cover 8 is provided with an opening 12 and has at one end of said opening a downwardly deflected baflleplate 13 which extends from one side of the base or receptacle 7 to the other side thereof. Pivotally secured at one of its edges to the lower edge of. the baille-plate 13 is another baffle-plate ll which also extends from one side to the other of the base or receptacle yet so as to move between said sides. Pivotally connccted at one of its ends to the lower portion of the plate 14 is a rod 15 which has mounted on its upper end a float 16 to rest on the surface of the water 17 contained in said base or receptacle. By this means it is apparent that the deflection of the plate l-i will be regulated by the quantity of water contained in the receptacle or base, for it is obvious as the level of the water is lowered by the evaporation, or raised by supplying water to the tank or receptacle, the float 16 will allow the lower end of the plate 11 to be lowered or will cause it to be raised, thus effectually providing, when the Water is sufficiently lowered, a baffle for directing the passage of air from the receptacle or base 7 upwardly through the opening 12 in the cover thereof. Located in-the receptacle 7 or base is another float 18 which has extended therefrom through a suitable opening in the cover 8 near the hasp or fastening device 10 an upright rod or member 19 which may be provided with a graduated scale to indicate the quantity of water contained by the base, for it is obvious that the float 18 will rise or fall with the level thereof. The cover 8 is also provided with another opening 20 which is preferably located therein near its hinged end or portion and is for the reception of porous or absorbent material, which in the present instance is shown in the form of a block 21 which is provided with a series of vertically disposed recesses or ways 22 for the passage of air downwardly into the receptacle or base 7 so as to contact in its further passage from the opening 20 in said base to and through the opening 12 thereof with the water. Mounted on the top of the base or receptacle 7 and circumscribing the openings 12 and 20 therein is a heating drum 23 which may be made of any suitable size, form and material, but by preference, of metal and elliptical in shape, in cross-section as shown. This drum may be extended to any suitable height above the top of the base 7 and is provided in its lower portion at a suitable point or place above the top 8 of said base with a horizontally extended floor 2 1 which together with the top or cover 8 and the walls of the drum 23 form or constitute a humidity chamber 25 which has communication with the receptacle or base 7 through the opening 12 as will be readily understood by reference to Fig. 1 of the drawings. Above the partition or floor 21 of the drum 23 said drum is provided with a series of openings 25 for the admission of air into said drum, and it will be observed by reference to Fig. 1 of the drawings, that said openings are located below the burner 26 which may be of the ordinary or any well-known construction, and which. has communication with and is supported by a tube 27 extended through the wall of the drum 23 and provided at its outer end with a valved device 28 for connecting the tube or pipe to a source of gas supply. As shown in Figs. 1 and 2 of the drawings the burner 26 is surrounded by a series of tubes or pipes 29 which are vertically located in the drum and have their ends opening through the partitionor floor 2 1, as well as through the lid or cover 30 for said drum. At its portion adjacent to one end of the base or re ceptacle 7, the drum 23 is provided with a vertical partition 31 thus forming a con duit 32 between said partition and the adjacent wall of the drum. This conduit communicates at its lower end with the opening 20 in the top or cover 8 of the base and receives the upper portion of the block or absorbent material 21, as is clearly shown in the different views of the drawings. The upper portion of the partition 31 is provided with an opening 33 for the passage of heated air from the drum downwardly through the said conduit and from thence through the ways 22 of the absorbent material and from thence into the water chamber or receptacle 7, and from thence out through the opening 12 in the top of said receptacle into the chamber 25 and from thence through the tubes 29, where the air will be super-heated by the heat from the burner 26, and discharged into the room. The top Or cover 30, is by preference, made of suficient size and shape to close the upper end of the conduit 32 and may be removable f'roin the drum if desired.

From the foregoing and by reference to the drawings, it will be readily understood and clearly seen, that when the construction shown in Figs. 1 and 2 of the drawings and above described is employed, gas may be supplied to the burner 26 and there ignited, when by reason of the heat gener ated by said burner and gas, air will be drawn into the drum 23 through the openings 25, and thus feed oxygen to the flames. In its heated condition and upward passage the air will pass through the opening 33 in the conduit 32 and from thence downwardly in said conduit through the same in the direction indicated by the arrows and also through the passage-ways 22 of the absorbent or porous material 21 and from thence into the base or receptacle 7 above and in contact with the water therein, and from thence out through the opening 12 into the humidity chamber 25 and then up through the tubes 29, from the upper ends of which it will be discharged into the room or apartment.

In the above-named construction and operation, it is obvious that as the water in the tank or receptacle 7 evaporates, the floats 16 and 18 will descend with the volume of water, and that in so doing, the indicator rod 19 will point out or indicate about the quantity of water contained in said receptacle, and also that the float 16 will so support the battle-plate 14: as to guide or direct the air current above the water level in said receptacle, toward the opening 12 in the top thereof. In the above-mentioned operation, air will contact with the upper surface of the water in said vessel, and will also be subjected to the moisture carried by the porous or absorbent member 21 after which it will pass out through the tubes 29 into the room in practically a pure condition and free from deleterious odors, dust or soot, yet carrying humidity about equal to that of the atmosphere. When it is desired to clean out the receptacle or base 7, the hasp 1.0 may be disengaged from the fastening 11 and the drum tilted so as to raise the cover of said receptacle, to such a position as to admit of access to the receptacle for supplying water or cleaning the same as is apparent.
