To all whom t may concern,.-

Be it lrnown that l, TrroMAs F. Harrow, a citizen ot the United `States, residing' at indianapolis, in the county ofh/iarion and State of Indiana. have invented new and useful improvements iu Oil Heaters, of which the following; is a specification.

This invention relates to heatingdevices in which oil is used for fuel; and the objects ara-61st, to provide an economical heating device where oil is used, that may be variously proportioned, as in a small stove to heat a room or two, or in furnaces to heat several rooms or an entire house; second, to provide greatly increased radiating surface; third, to insure circulation which will always take the cold air from below the heater through the heater and discharge it above in a heated condition; fourth, to provide means for conserving the heat and for applyinp,- it more uniformly to the circulatory system of the heater; fifth, to prevent the waste of any overflow of fuel oil used, and sixth, to make a simple, inexpensive, and durable heater.

I accomplish the above objects by the mechanism illustrated in the accompanying drawing', in which- Fig. l is a top plan view of my heater as a. small stove, showing).` same without a casing; in full lines, and showing` the casing in dotted lines. Fig. 2 is a vertical section of same on the line 2 2- of Fig. 1. 3 is a horizontal section on the line 3-3 of Fig. 2. Fig. et is a front elevation of a furnace .heater made in accordance with my invention, for heating` several rooms, broken away in part to show the interior construction and also broken away at the base and extreme top of the casing', the view also showing; a casing in full lines, and Fig. 5 is a horizontal section on the line 5-*5 of Fig. e.

Lilie characters of reference indicate like parts throughout the several views of the drawing.

The heater body comprises side 6, of sheet or cast metal, a bottom 7 and cap 8, each with inturned marginal flanges 9 to receive the sides 6 in the manner shown; the as sembly being secured as one Vunit by the corner shaft-bolts 10. The cap 8 has an opening over which a pipe-collar 11 is bolted.

The side 6 has an opening through which an oil burner 12 of any desired type is intro duced, and through which a basket 13, containing an assembly ef irebrcks or other heat retaining' elements let, is placed above `the burner and is adjusted. rlie basket may l? 2 or out of woven wire as shown in F Il. lt is suspended by any suitable means, such as by hooks 15 from perforated lugs 16 dependingfrom the cap as shown. This opening` in. the side@ closed by a door 21"?, shown as an upwardly sliding` door .in Figs. 1, 2 and `3, and a hinged door in Finis. 4 and l5.

The bottom '7 is preferably sloped from the sides of the body toward the center, and at the lowest portion a trough 17 is formed which slopes toward the rear end of the heater where there is a hole through the bottom in the trough connecting with a drain pipe 18 under the stove. Any overflow of oil from the burner drains into the trough 17, and from it through pipe 18 to a suitable holder from which it is used over again in the burner. rlhe base sets on feet 19, and under it are plurality7 of arms 20, which are pivoted to the bottom 7 to enable the arms to fold back under said bot-tom when not in use, and to be'swung out as supports for a casing' 21 when such an adjunct to the heater is desired. 'The ends of the casingi are fastened by bolts, rivets, or screws to extended flanges' 22, from the front wall.

l will now described a very important feature of my invention, i. e., vertical air tubes 23, which connect openings through the bottom 7 with registering openings through the cap 8. These tubes ta re the cold air which settles by gravity nearest the floor, and conduct it through the body of the heater where it is made hot by the'heat from the burner and stored heat radiated from the contents of the basket 13, and discharge it through the top of the heater. A plurality of these tubes is shown in two rows, in Figs. l to 8, inclusive, and arranged in a circle in Figs. fl and 5, the shape of the stove beine' obviously optional with the designer, and the number of tubes dependent upon the size of the heater required and perhaps other conditions.

In order to insurean upward tlow of air through the tubes 23 ll prefer to expand them upwardlythat is, make them of greater diameter at their tops than at their bottoms. They are assembled at each end around inturned collars 24 from the top and bottom, respectively, of the heater.

Having thus fully described my invention,

what I claim as new and Wish to secure by Letters Patent, of the United States, is

l. In an oil heater, a body comprising a top, bottom, and side, said bottom havinga plurality of openings and said top having an equal number of openings, and tubes connecting each opening in the bottom With a corresponding` opening in the top, said tubes being of increasing area in cross section from top to bottom, a source of heat on or near the bottom, a basket above the source of heat containing a material to store heat, said source oi heat and basket being surrounded by said tubes.

2. ln an oil heater, a body comprising a top, bottom, and side, said bottom having a plurality of openings and said top having an equal number of openings, and tubes connectine` each opening in the bottom with a corresponding opening in the top, said tubes being of increasing area in cross section from top to bottom, and an oil burner near the bottom, and a basket above it containing fire brick or the like and surrounded by said tubes.

3. In an oil heater, a body comprising :i top, bottom, and side, said bottom having a plurality of openings and said topl having an equal number of openings, tubes connecting each opening in the bottom with a corresponding opening in the top, an oil burner near the bottom a basket yabove the burner containing fire brick or the like and surrounded by the tubes and an oil trough below the burner also surrounded by the tubes and discharging outside of the body.
