ADOLPH RICHTER, OF ARLINGTON, NEW JERSEY.

ALCOHOL-STOVE.

1 Application filed May 22, 1907.

To all whom it may concern:

Be it known that I, ADOLPH ltronrna, a citizen of the United States, and a resident of Arlington, in the county of Hudson and State of New Jersey, have invented a new and Improved Alcohol-Stove, of which thefollowing is a full, clear, and exact description.

My invention relates to stoves, my more particular object being to produce a type of stove suitable for cooking by means of alcohol.

My invention further relates to certain improvements made for the purpose of promoting the safety of the stove, and to render its Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures- Figure 1 is a side elevation, partly in section, showing one form of my stove in which the alcohol tank and the burners are arranged upon opposite sides of the main supporting stem, the burners being surmounted by a rest for supporting vessels to be heated; and Fig. 2 is a fragmentary section upon the line 22 of Fig. 1, looking in the direction of the arrow, and showing the cooling tank and the overflow tank, together with connections Mounted upon a pedestal 3 is a standard 4 which supports a tee 5. Connected with this tee is a pipe 6 provided with a hand valve 7. A tank 8 contains a quantity of alcohol 9 and is supported upon the upper end of the pipe 6, this pipe being bent substantially into an Lshape. A rest 10 consisting of parallel rods is supported upon a stem 11, being provided for that purpose with a tee 12 which slidably engages this stem. A thumb-screw 13 extends through one side of the tee 12 and engages the stem 11. By loosening the thumb-screw 13 the tee 12 and rest 10 may be adjusted to any desired height and then fixed in the position chosen. At 14 is shown how a vessel may be placed upon the rest 10.

Two elbows 15, 16 are connected together by a sleeve 17, and by a sleeve 18 the elbow 16 is connected with an elbow 19. From the latter a sleeve 20 extends downwardly and supports an elbow 21. A horizontally disposed pipe 22 is connected with the elbow 21 and also with another elbow 23. Engaging the latter is a sleeve 24, which is connected I with an elbow 25, and this elbow is connected l Specification of Letters Patent.

Patented May 26, 1908.

Serial No. 374,987.

From the elbow 26 a sleeve 28 extends down wardly and supports an elbow 29 which is closed by a screw plug 30. A tank 31, made preferably of metal, has the form of a rectangular box and is suspended from links 32 which engage the sleeves 18, 27. By this means the tank is hung from these sleeves. The tank is self-balanced; that is to say, when left to itself it assumes, under the influence of gravity only, a position suitable to enable it to hold water.

Tees 33 are mounted upon the pipe 22. Connected with these tees and extending upwardly therefrom are burner stems 34 provided with hand valves 35 and resting upon these burner stems are cups 36. Drain tubes 37 are connected with the cups 36 somewhat above the middles thereof. These drain tubes are connected with a drainage tank 38. The latter is provided with a hand valve 39 and is adapted to hold a quantity of alcohol 40. By means of the hand valve 39 this alcohol can be removed at will.

The operation of my device is as follows: A suitable quantity of alcohol having been filled into the alcohol tank 8, the hand valve 7 is manipulated so as to allow a portion of this alcohol to pass through the pipe 6 and its various connections to the pipe 22. From here the alcohol tends to pass upwardly through the burner stems 34, but unless the hand valves 35 are in proper position, the alcohol can not pass them. The operator therefore turns the hand valves 35 to any desired extent for a moment only and thus al lows a suitable quantity of alcohol to rise into the cups 36. For this purpose the valves 35 are entirely independent so that either one of the cups may receive alcohol to the exclusion of the other and at the will of the operator. If it should happen that a little too much alcohol is filled into the cup,

the excess passes off through the corresponding drain tube 37 and into the overflow tank 38. One or more of the cups being thus partially filled, the operator next ignites the alcohol contained in the cup and the cooking 'into the drain tube.

removed automatically and flows into the overflow tank 38, as above described. This tank is closed, as indicated in Fig. 2. Each drainage tube 37 is of sufficient size to enable the air to pass in one direction while the alcohol travels in the opposite direction.

The burning of alcohol in the cups 36 does not cause the ignition of alcohol in the overflow tank 38, for the reason that the flame is extinguished by the entrance of the alcohol In this connection it will be noted that an alcohol flame is extinguished with comparative ease, especially if any metallic members in contact with tho flame are not unduly heated.

' The cooling tank 31, having been previously filled with water, maintains the burner stems 34 at a low temperature, and this prevents the cups 36 from becoming unduly heated. The water in the tank 31 being thus rendered warm by taking up excessive heat from the burner stems, may be used for domestic purposes.

I do not limit myself to the particular form of stove shown, for the reason that various changes therein may be made without departing from the spirit of my invention. \Vhile I preferably use alcohol as a fuel, I do not intend to limit myself thereto.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a stove, the combination of a tubular member connected therewith for supplying thereto a combustible liquid, a tank mounted upon said tubular member and depending therefrom, a portion of said tubular member extending within said tank for the purpose of being submerged in a liquid contained therein, and burners mounted upon said portion thus submerged, said burners projecting away from said liquid.

2. In a stove, the combination of a tank for holding alcohol or the like, a supporting stem, a member connected with said tank and with said stem and having a general tubular form for conveying the liquid from said tank, burners connected with said member of tubular form, and a water tank so (lisposed that a portion of said member of tubular form is submerged within it for the purpose of maintaining a low temperature in said member of tubular form and said burners.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
