' This invention relates to heating apparatus and more particularly to a liquid fuel burner of the wick type.

In accordance with this invention there is provided a wick type liquid fuel burner provided with an individual liquid fuel reservoir, the bumer being resiliently mounted on said reservoir and thus displaceable with respect thereto, at fording ready removability with respect to an element to be heated.

Other objects and advantages will be apparent from the following description taken in connection with the accompanying drawing, in which,

-The figure shows schematically a burner arll rangement contemplated by this invention.

Referring to the drawing, there is indicated as the element to be heated, a generator 10 for absorption type refrigeration apparatus so well known as to here require no further illustra- 10 tion or description. There is shown only the lower end of the generator and the lower end of a heating flue 11 which extends vertically through the generator 10 for heating absorption solution contained in the latter. For reduction of heat loss by radiation, the generator is enclosed by thermal insulation material 12. Below the lower end of the heating flue 11 there is mounted a suitable support such as the bracket shelf 13 on which rests a reservoir 14 for liquid fuel, which latter may be conveniently constructed of glass as well known in the art. In the top of the reservoir 14 is a circular opening in which there is fixed a cylindrical sleeve 15 provided with an outward flange 16 at its upper end. A burner 17 is of a type well known in the art provided with a guide,

not shown, Ior the wick l8 and a wick screw 19- for adjusting the size of the flame at the upper end 20 of the wick. Around the upper end of 0 the wick, the burner 1'1 is provided with a short chimney 21, the upper end 22 of which is adapt- -ed to receive the lower end of the heating flue 11 when the chimney and flue are brought into coextensive relation as shown.

There depends from the burner 17 a tubular portion 23, affording communication with the reservoir 14, and the wick 18, carried by the burner, extends downwardly through the tubular portion 23 into the reservoir 14. The tubular portion 23 of the burner is vertically reciprocable in the fixed guide sleeve 15 so that the burner 17 and reservoir 14 are relatively displacrable. A spring 24 coiled about the tubular portion 23 of the burner between a shoulder 5 25 on the burner and the flange 16 of the sleeve 15 maintains an upward tension between the burner and reservoir.

The heating element is placed in position by moving the burner 17 downwardly toward the reservoir 14 against the resiliency of spring 24 w and resting the reservoir 14 on the bracket support 13 under the lower end of the heating flue 11. When downward pressure on the burner 17 is released, the spring 24 raises the burner 1'7 upwardly until the upper end 22 of the stub chimney 21 engages the lower end of flue 11 in coextensive relation therewith. To 1311 the reservoir, trim the wick, or otherwise service the heating element, the burner 1'1 may be pressed downwardly against the resilient action of the 7 spring 24, thus disengaging the \upper end of the chimney and lower end of the flue, whereupon the element may be removed from its support.

It will be obvious to those skilled in the art' that various changes may be made in the construction and arrangement without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawing and described in the speciflcation but only as indicated in the following claim.

- We claim:

In combination with an element to be heated provided with a vertical heating flue, a reservoir for liquid fuel having a circular opening in the top thereof, a cylindrical sleeve fixed in said opening, a support for said reservoir below the lower end of said flue, a wick type fuel burner having an upwardly extending chimney and a depending tubular portion affording communication with said reservoir and reciprocable in said sleeve, and a coil time 1111118 around said tubular portion between said burner and a flange on the upper end of said sleeve to urge said burner upwardly with respect to said reservoir to normally maintain the upper end of said chimney in coextensive relation with the lower end of said flue.
