DEVICE FOR THE COMBUSTION OF LIQUID FUEL.

SPECIFICATION forming part of Letters Patent No. 320,533, dated June 23,1885,

Application filed January 22, 1883.

To all whom it may concern;

Be it known that I, JOHN D. BODwELL, of the city and county of San Francisco, State of California, have invented an Improved Device for the Combustion of Liquid Fuels; and I hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to an apparatus in which the combustion of liquid fuel may be carried on, and it consists of a shallow chamber,ofiron,into which theliquid is led through pipes from a supply-tank having walls of thinner metal arising from the sides of the receiver, and extending up to a considerable 1 height above it. These sides have slots or openings to admit air, and shutters or valves are adjusted to these openings, so that the supply of air may be regulated at pleasure. Similar walls arise from the central portion of the receiver to about the same height with the outer walls, and when desired air is also admitted through this interior space to aid the combustion.

Referring to the accompanying drawings for a more complete explanation of myinvention, Figure 1, Sheet 1, is a perspective view of my apparatus for the combustion of liquid fuel. Fig. 2, Sheet 2, is a view of the combustionpan with the walls left off. Fig. 3, Sheet 3, is

a transverse section on a smaller scale of my device, showing its application to a cooking stove.

A is a shallow receiver or pan, into which the liquid is admitted by one or more pipes,B,

3 5 from a tank, G. This tank may be situated at any convenient point near to or distant from the burner, and at a sufficient heightto allow the liquid to flow from it to the pan by gravitation. The rapidity of the flow is controlled by one or two cocks, D, in the supply-pipe. The pan Ais made of such a shape and size as to fit a grate or the fire-space of any stove or furnace where it is to be used,and is made, preferably, of castiron or other metal of suf- Renewed April 30, 1885.

ficient thickness to retain considerable heat 5 when it has been once heated. Around the outside of this pan is a wall, E, of thinner metal, which rises to a considerable height above the edges of the receiver, and these walls have narrow horizontal slots or openings F, for the admission of air to assist in the combustion. These slots are provided with doors or valves Gr, so hinged or attached at the upper edge that they may be opened or closed more or less to control and direct the air admitted through the slots to aid in the combustion.

The central portion of the pan A may have an opening, H, made through it, of ashape to conform approximately to the exterior Outline, although this is not absolutely essential. This opening is also surrounded by an inclos ing wall, I, like thatsurrounding the exterior of the pan, and air is admitted through this passage, if desired, to assist the combustion.

This apparatus I have designed especially for use in the combustion of a liquid fuel which I have invented, and for which'I have made a separate application for Letters Patent, and I have found that it produces a very perfoot combustion without the central air-pas sage, which may in many cases be dispensed with.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The base A, having the interior continuous channel and central opening, H, in combination with the central extension, I, and an eX- terior surrounding extension E,provided with continuous longitudinal openings F, and curved adjustable valve G, extending the length of opening F, as set forth.

In witness whereof I hereunto set my hand.

V JOHN DAMON BODVVELL.
