srncrnca'rron-foi mg maer aemued mam Patent No. 11,905, dated April 9, 1901. ori inate. 596.231, amt Deoember'I, ism. Application mas filed October 26, 1898. emu. No. 694,649.

To all whom it may concern.- i l Be it known that I, WILLIAM H. WILDER, a

citizen of the United States, residing at Gard nor, in the county of Worcester and State of Massachusetts,have invented certain new and useful Improvements in Oil-Stoves, of which "stove adapted to be used with petroleum without a wick other than an initial lighting medium; and the object of my invention is to provide a stove in which the burner and oilreservoir are adjustable in relation to each other, so that the oil-level in the fuel-holder of the burner may be raised or lowered.

In carrying out the invention I employ a reservoir of the type used in the ordinary student-lamp, and thus secure a maintained oil-level, and this level is controlled by raising or lowering the reservoir audits oil chamher in relation to the burner or by raising or lowering the burner in relation to the reservoir, and it will thus be seen that the-level of the oil in the burner may be'accurately adjusted to the requirements of the work, and after once adjusted this level will be automatically maintained by the fuel from the reservoir. This construction renders unnecessary the interposition of a valve in a one: burner stove so far as the ordinary operation of a valve is concerned-namely, to control the feed of the oil to the burner-but one may be interposed with advantage in order to cut off or diminish the flow of oil without lower ing the reservoir or'raising the burner to drain the latter, which otherwise would be necessary, and thus by the use of the valve the adjusted position of the parts may be maintained and the oil additionally controlled. Where two or more burners are used, it is desirable to interpose valves, asit may not be necessary to use all the burners in the same way at one time, and in this case the supply to the burners may be regulated by the valves.

In the accompanying drawings I have shown the invention as applied to a form of stove shown in a companioncase filed of even date herewith and marked Case A.

Figure 1 is a view of a stove with my-improvements. Fig. 2 is a detail of the adj usting means for the reservoir. Fig. 3 is a diagram showing the invention as applied to a stove with a series of burners. Fig. 4 is a detail view of the pipe.

In the drawings, A is the frame of the stove surmounted by a top B, and'supported within the frame is a liquid-fuel holder having above it a combustion-chamber, both of a construction similar to that particularly shown and described in an application filed April 19, 1897, Serial No. 632,858, and hence not requiringspecifiedescription,especiallyin view of the fact that I do not limit myself in the present case .to the application of the invention to any specific form of burner. The reservoir is shown at C and is seated in an oilchamber 0, the feed' being regulated from the 10 reservoir to the chamber by the inlet of the air, which enters the'reservoir and discharges more oil as soon as the level of the oillowers in the chamber. This is a well-known form of construction. A bracket D extends from the side or end of the stove, and this bracket 1 has four arms (1 extending at right angles, and upon these arms and supported by them is a vertically-movable support E, which may be made slightly bowl shape to receive the reservoir and its chamber. This support E has triangular pieces e extending. from its under face at equal distances apart, and these pieces are serrated or grooved on, their inclined faces and are adapted to rest upon the arms (1. The support-E has a handle F, by which it may be turned, and it will be seen that by this operation the inclined faces of the projections e slide over the arms (1, and thus raise or lower the reservoir and its chamher and change the level of the oil in the fuelholder of the burner, this level of course being always that of the oil-chamber of the reservoir. The vertical movement of the reservoir audits chamber is permitted by the flexibility of the pipe G, extending between the oil-chamber and the burner, and to secure suflicient flexibility I make the pipe G flattened in-cross-section and extend it beneath the burner and make a connection at theside opposite to that on which the reservoir is located, so as to give suilicient length to the 1 with a connection therefrom to each burner and with a valve K in each connection. The flexible pipe G extends from the oil-chamber of the reservoir to the end of the main-line pipe J.

'It will be understood that instead of mak- 'ing the oil-chamber adjustable in relation to 5.

the burner the burner may be made adj ustyable in relation to the oil-chamber without departing from the spirit of my invention.

While I have used the term oil in the description and claims, it will be understood that this includes any kind of liquid fuel.
