Specification of Letters Patent. Patentd June 13, 1916.

Applicationaled November 8, 1911. Serial No. 659,193.

more particularly to heating lamps, and it has for its object to provide a device of this character which will be particularly adapted for use in chicken houses and like places to heat the same or the water provided for the fowls and prevent it from freezing.

Further objects of the invention are to provide a lamp that will be simple and cheap to manufacture, but more particularly onethat will burn for a long period of time without attention.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, 4the novel features being pointed out in the claims at the end `of the specification.

In the drawings: Figure 1 is a front elevation of a chicken house stove embodying a lamp constructed in accordance with and illustrating one embodiment of my invention; Fig. 2 is a vertical section taken substantially on the line 2-2 of Fig. 1, and Fig.

3 is a perspective view of the wick holder of the lamp.

Similarl reference numerals throughout the several figures indicate the same parts.

Referring more particularly to the drawings, the stove in which the lamp of my present invention is in this instance embodied comprises a lower reservoir section 1 and an upper removable section 2, both preferably of box-like form, and the upper one being provided with a metal stove top orv radiating surface 3 on which the vessel 4, containing the water for the fowls, may be placed. The

two sections are respectively provided with draft and vent openings 5 and 6.

Within the lower section 1 is arranged an oil reservoir 7 of any suitable form having a lamp tube 8 extending nearly to the bottom thereof, as usual, and out through an aperture 9 at the top, considerablylarger than the tube to provide avent for the vapors from the oil, the upper projecting end ofthe tube being supported, in the vpresent invent hole (not shown).

Slidably adjustable vertically withinthe tube 8 is a wick holder that is preferably constructed inj the form shown in Fig. 3, in which instance it comprises an inverted ,loop 11 embodying slightly flared, upwardly projecting, resilient arms 12 and 13. These arms are of unequal length, the shorter one 12 being considerablyshorter than the burner tube` 8 so that it will have a considerable range of adjustment, .being provided at its upper end with a tubular portion or eye 14 through which the wick is passed. This eye is preferably quite a little smaller in external diameter than the burner tube, while its inside diameter is approximately that of the4 wick for reasonsthat will later appear. The longer arm 13 of the holder is extended sufliciently to project beyond the mouth of the burner tube 8,. as shown 1n Fig.

2', tol `provide a means for operating vthe holder up and down and adjusting the wick, and to this end its extremity .preferably proceeds laterally, as shown at 15. lVhen the holder is formed from a single piece of wire, as I prefer to construct it, this operating portion 15 may terminate in a loop or eye 17 providing a finger piece or handle, and the wick holding eye 14 at the extremity of the other arm may be formed in like manner.

The resilient arms 12 and 13 frictionally engage the inner walls of the tube 8, being compressed upon insertion and serve to re-.

tain the holder at any desired elevation.

As before mentioned, the wick 16, which may be of the ordinary twisted variety, passes through the eye of the holder and is, therefore, much smaller than the inside of the burner tube. Furthermore, the holder, or at least the holding arm 12 thereof, being much shorter than the burner tube and always below the mouth of the latter, the upper end of the wick extends upwardly within the latter, but being so supported is spaced from the walls thereof all around. Preferably the eye 14 of the wick holder Vengages the wick at an intermediate point and only for a portion of its length so that the lower end of the wick isl also spaced from the walls of the tube 8 and free to absorb the oil therein.

stance, by ja cap 10 that should also have a The main advantage of my construction, above described, lies principally in the fact that as the wick is held free from contact with any part, and particularly with they walls of the burner tube, in the region of the point of combustion, the carbon and other particles that accumulate on a burning wick, and in ordinary lamps, necessitate frequent trimming, are not allowed to deposit themselves on lthe lamp tube and choke the wick or upon the wick itself, but fall down between the wick and the tube and may be removed from the latter from time to time but at much longer intervals than those at which an ordinary wick would have to be trimmed. In fact, most of these particles are vremoved with the wick and its holder when the latter is drawn out of the tube. The mouth of the tube nevertheless prevents the air from reaching the wick too far below the end at which combustion is desired, though the small volume of gas generated within the tube is burned within the mouth thereof, as sufficient air not consumed by the burning oil finds its way partly within the tube for this purpose. A low, even, slow burning flame capable of maintaining itself for a long period of time is the result. In fact, I have burned a lamp of substantially the design indicated for two or three weeks without attention of any kind.

Aside from the advantages above mentioned, it will be readily seen that the structure involved is one that can be produced at a very low cost, the wick holder particularly being exceedingly simple.

I claim as my invention:

1. In a lamp, the combination with a closed oil reservoir, of a wick tube having gas tight walls extending downwardly to the lowest possible level of oil in the reservoir, a wick substantially smaller than the tube arranged therein to provide a continuous open space within the tube extending from the mouth thereof down to the surface level of oil in the tube, and means arranged below the upper ends of both the wick and tube for holding the upper or burning extremity of the wick spaced from the adjacent walls of the tube so that combustion of the gas generated within thetube may take place below the top of and partly within the burner tube.

In a lamp, the combination with a burner tube of uniform inside diameter, of a lwick holder slidably adjustable in the tube and removable from the mouth thereof and a wick of smaller diameter than the tube maintained therein by the wick holder with its upper or burning extremity in spaced relation to the inner walls ofthe tube at the mouth thereof so that combustion may take place below the top of and partly within the burner tube.
