OIL-STOVE AND BURNER.

SPECIFICATION forming part of Letters Patent No. 513,713, dated January 30, 1894.

Application filed March 6 1893- fierial No. 464,675. (No model.)

To whom it may concern.-

Be it known that ,I, EDWIN G. MUMMERY,

a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Oil-Stoves and Burners; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification;

My invention relates to certain new and useful improvements in an oil heating stove, and in a novel construction of a burner to be used in connection therewith. My improved burner is not, however, limitedin its application solely to oil heating stoves, as my invention contemplates its use Wherever it may be found adapted.

The aim of my invention, chiefly, is to provide a burner whereby a more perfect cornbustion will be secured, and whereby a stove may be heated more efficiently than with burners heretofore employed.

My invention therefore consists of the, devices and appliances, their construction, combination and arrangement, as hereinafter specified and claimed, and illustrated in the drawing submitted herewith, which is a vertical section through the burner and through adjacent portions of an oil stove.

I carry out my invention as follows:

A represents the shell of a stove, surrounding the tank chamber.

A is a portion of the shell surrounding a hot air chamberA said hot air chamber surrounding the combustion chamber A A is a portion of the shell of the stove located above said hot air chamber and combustion chamber. The upper portion of the stove may be constructed in any desired manner.

B denotes the oil tank or reservoir.

0 0 denote the walls of the wick chamber 0 p B is the supply pipe leading from the oil tank into the wick chamber.

0 is the wick.

D is an interior air flue located within the inner wall of the wick chamber, forming an air chamber D therebetween.

Above the wick chamber I locate perforated air and vapor mixers or cylinders E and E spaced one from the other to form an air and vapor mixing chamber E above the wick and between said mixers or cylinders.

F denotes a deflecting drum separating the hot air chamber A from the combustion chamber A said drum being open at its lower end, and projecting preferably downward from the horizontal plane of the upper extremity of the mixers E E below the upper end of the wick chamber, forming an air space between the drum and the adjacent portions 'of the wick chamber and mixers, as shown.

Above the hot. air chamber A is located a partition A separating the hot air chamber from the portion of the stove thereabove. Below the hot air chamber 'A is located also a partition or wall A, spaced from the oil tank and extending over the top thereof and downward over the inner face thereof, forming therebetween an angular air passage a, which passage also extends between the oil tank and the outer case or shell A. As so constructed the oil tank is exposed to the air at its base, the air flue at extending about its other three sides, thus keeping the tank cool. The wall A separates the \tank from the hot air chamber A The downwardly projecting portion of the partition A forms an air space a between it and the adjacent portion of the wick chamber, said air space being openat the base, as indicated in the drawing.

It will be seen that between the flue D and the wick chamber is formed a central airflue a communicating with the air passageD'. The chambers A and D are closed at their upper ends, as shown at a a so as to deflect the air rising therein, and compel it to pass through the air and vapor mixing cylinders E and E into the chamber E, which is made open at the top, as shown, for the escape of the products of combustion therefrom into the chamber A thereabove. I prefer also to extend the flue D upward above the air and vapor mixer cylinders E E into the chamber A so as to carry a supply of air into the upper regions of combustion to produce perfect combustion.

It will be evident that the supply of air provided about the oil tank in the air space a. is deflected under the lower edge of the partition A rising into the hot air chamber through the air space a'. At the sametime air rises independently of the space a into the lower end of the space a, as indicated. The air thus rising through the space or flue a' enters the chamber A where it is heated. The escape of the air from the chamber A is prevented, except as it is deflected underneath the drum F and rises within the chamber A and is directed through the perforated cylinder E. All the air entering the air flue a is compelled to pass through the perforated cylinder E. Thus through the cylinders E and E a large supply of air is directed into the mixing chamber E affording an ample supply of air therein at the lower regions of combustion. Attention is called to the fact of the location of the two perforated cylinders above the wick chamber, or so as to supply an abundance of air thereabove. The superior utility of this construction is obvious.

-What I claim as my invention is- 1. In a stove provided with a hot air chamber, an air and gas mixer within said hot air chamber and opening through the top thereof, a wick tube below said air and gas chamber, and a deflector around said air and gas chamber for causing the hot air to pass thereinto, substantially as set forth.

2. In an oil stove, the combination with a shell provided with a partition, of an air and gas mixing chamber opening through the partition, a wick tube below the, chamber, an open ended tube having its upper end projecting through the partition and its lower 4o end extending down within the wick tube, substantially as set forth.

3. In an oil stove, the combination with a shell provided with a partition forminga combustion and hot air chamber, perforated shells depending from the partition into the hot air chamber, which forms an annular space which opens into the combustion chamber, a wick tube below the shells and communicating therewith, and an open ended tube extending from the partition down within the inner perforated shell and wick tube, the upper end of which tube extends above said partition, substantially as set forth.

4. In an oil stove, the combination, with a shell provided with an annular partition, the inner edge of which is provided with a depending cylindrical flange, of a hollow wick tube within the flange, the upper end of which is provided with a burner and an oil tank between the shell and the flange and communieating with the wick tube, said tank being spaced from the shell, the partition and the flange, substantially asset forth.

5. In an oil stove, the combination with a shell provided with two partitions, one above the other, of a flange depending from each partition, two perforated shells, an open ended air tube within the wick tube, and an oil tank between the lower flange and the shell and communicating with the wick tube, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.

EDWIN G. MUMMERY.
