ALFRED LEISTMANN, OF BROOKLYN, NEW YORK.

GAS-HEATER.

Application filed March 2. 1920.

To all whom it may concern Be it known that I, ALFRED LnisTMANN, a citizen oi? the United States, residing at Brooklyn, in the county of Kings and State 01'. New York, have invented a new and useful Gas-Iileater, of which the following is a specification.

This invention relates to new and useful improvements in heating stoves, and more particularly to portable stoves of this character especially adapted for burning gaseous fuel.

The primary object of the invention is to provide a. heating stove having means to increase the heating surface thereof, thus insuring the maximum amount of heat from a given quantity of fuel.

:1. "further object of the invention is to provide a stove wherein the elements thereof may be readily and easily removed and replaced, in the event that it becomes neces sary to repair or clean the same.

1Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a longitudinal sectional view through a stove constructed in accordance with the present invention.

Fig. 2 illustrates a plan view, the upper plate of the stove being shown as partly broken away, and V Fig. illustrates a fragmental detail view oi the mixing chamber of the burner.

Referring to the drawings in detail, the reference character 1 designates the outer casing of the stove, the same being preferably circular in cross section, but it is to be understood that the design of the stove may be changed to meet various requirements of use.

A supporting collar 2, provides the support for the outer casing 1, the flange formed adjacent the lower end of thecollar 2, and indicated by reference character 3 forming an abutment for the lower extremity of the lower casing 1.

T his supporting collar 2 embraces av portion of each of the supporting legs 4, ad

Specification of Letters Patent.

Serial No. 362,695.

jacent the upper extremity thereof,.and as shown the supporting collar 2 is provided with openings disposed in registry with suitable openings formed in thelegs 4, which openings are also in registry with openings formed in the outer casing 1, to accommodate the bolts 5, whereby the outer section 1, collar 2, and legs 4 may be rigidly secured together.

Extending inwardly from the legs at are the lugs 6, which lugs provide supports for the protecting plate '7, which is formed of suitable heat resisting material, and adapted to protect the surface on which the stove is supported from the heat radiating from the stove proper.

Having connection with the inner side wall of the legs 4, adjacent the upper end thereof, isa tubular inner casing 8 which is secured to the legs 4: by means of the bolts 5, the bolts 9 being also provided for securing the inner'section 8 in proper spaced relation with the outer casing 1, thus providing an annular heat passageway 10.

Formed integral'with the outer casing 1, is a relatively flat top 11 provided with a series of openings 12disposed in suitable spaced relation with each other adjacent the periphery of the outer casing 1, the openings being. however provided directly over the annular heat passageway 10 to permit the heat radiating from the inner section 8 to pass upwardly through the openings 12.

Anopening 13 is formed in the stove top 11, substantially centrally thereof, and accommodates the upper extremity of the burner supporting rod 14, the upper end of said rod being threaded to receive the knob 15, the lower end of which is adapted to contact with the upper surface of the top 11 to support the rod 14 in proper relation with the inner walls of the inner section 8.

As shown, the lower end of the rod 14 is threaded to cooperate with suitable threads formed on the wall of the opening 16 of the burner 17, whereby the burner may be secured to the rod 14.

v Embracing the rod 141, are a plurality of spacing collars 18 that are disposed throughout the length of the rod, which collars are provided for supporting the baffle plates 19, in suitable spaced relation with each other, the battle plates being shown as clamped between adjacent collars. Openings 20 are formed in each of the battle plates 19 and disposed in a manner so that the openings of one plate lie directly under the openings of the adjacent plate to permitthe heat to pass upwardly through the openings.

The burner may be of any predetermined configuration but as shown, the same coinprises a plurality oi arms 21 having the upper surfaces thereof apertured as at 22 to permit the gas entering the burnerproper V to pass outwardly therethrough. Supported adjacent the lower :end of the stove proper 1s a mixing chamber comprising the lnner pipe 23 naving threaded connection with the burner, as at 2d, the pipe 23 being provided with'an elongated opening 25 formed in the upper surface thereof, which opening is ada ited to re ister with the ooenin 26 formed in the adjustable sleeve 27, whereby the amount of air entering the mixing cha nber may be regulated according to the supply of fuel passing therethrough.

Secured to the opposite end ofthe pipe 23 is the thinible 28 having a reduced portion 29 provided with internal threads to accommodate thethreadsof the connecting pipe 30, the discharge nozzle 31 being removably supported within one end of the pipe 30 and having its discharge end terminating at-a point adjacent one end of the elongated opening 25, so that the air entering the mixing chamber, directly contacts with the fuel from the discharge nozzle. I

A finishing ring 32 is supported by top 11' and is provided with a downwardly curved flange 33 which ring is adapted'to partially cover the openings 12 to increase the draft through the openings. Y

In the operation of the device it is of course apparent that a suitable valve is employed'lor controlling the supply of gaseous fuel, to-the burner proper, which valve is opened to permit a predetermined quantity of fuel to pass into the burner. The burner is lighted with the result that the heat generated by the burner passes upwardly contacting with the battle plates to heat the same, thereby increasing the heating surface of the stove. V

Havmg thus described the 1nvent1on, what I claim as new is 1. A heater including supporting legs, an

outer cylindrical casing having connection with the supporting legs, an inner casing having connection with the supporting legs and disposed in spaced relation with the outer casing, a cover, said cover having a plurality of openings formed therein, a supporting rod having one extremity disposed in one of the openings of the cover, burner having threaded connection with one end of one end of the supporting rod, and'means for feeding iuelto the burner. 7

i8. iL heater including supporting legs, an outer and an inner casing having connection with the supporting legs, said casings being disposed in spaced relation with each other, a cover for the casings, said "cover having a central opening, a supporting rod having one extremity threaded and extending through the opening, a knob positioned on theupper end of the supporting rod for securing therod to the cover, thelower end of I said supporting rod terminating at a point adjacent the lower end of the casings, a burner having threaded connection withthe lower end of the supporting rod, a plurality ot spaced baffle plates disposed on the supporting rod, and a collar positioned between each of the bailie plates, and means for supplying fuel to the burner.

"In testimony that I claim the foregoing as my own I have hereto affixed my "signature in'the presence of two witnesses.

I ALFRED LEISTMANN,
