WICK- BURNER.

A-ppncanon filed July a3,

T0 allwhom t may concern:

Be it known that I, FnEDERrcK F.l BEN- NETT, a citizen of the United States of lAmerica, residing atjYpsilanti, in the county of IVashtenaw and State of Michigan, llave invented certain new and usefullmprovements in `Wick Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to oil burners of the wick type vand consists in certain improvements in construction whereby the wick is readily accessible and may be more easily adjusted and removed than in the usual types. The features of construction und the advantages to be obtained therefrom are fully set forth :hereinafter and illustrated in the accompanying drawings, wherein :f-

Figure l is a4 sectional elevation of rthe burner;

Figure 2 isa plan view thereof.; y

Figure 3 is a plan view of the adjusting handle;

Figure A is a longitudinal section through the adjusting mechanism.

The improved burner comprises an outer Lcylindrical casing A having a raised bottom plate B and a central tubular member C, all suitably secured together to-majke an annular oil chamber A with an inlet connection A2 communicating therewith near. the bottom member B. The latter has' an annular recess B near the outer wall. Ay and .the adjacent annular shoulders B2 forming one wall 4of :said recess. j D is a cylindrical tubular member arranged coaxially with the outer casing A to form the annular `wick chamber E therebetween. The cylinder Dis `held in position within the casing by'having the lower end inserted in the recess B and engaging thev annular shoulders B2. F is .a cover member having the annular flange F closely fitting the walls of the tubular member D and secured thereto by suitable means such as by indenting the metal of rone member into the other. For clamping the member D in position there is a stud G secured to the central tube C by a bracket G2 and extending through kan aperture F? in the cover member where it engages the wing nut H is an annular wick arrangedr inthe annular chamber E between the `outer cas ing and the cylindrical member D. `The wick is supported by a metallic sleeve I provided with a seriesl of perforations J ar- 1923'. Serial No. 653,265.y

ranged in helical lines around the periphery thereof. y i

For raising and lowering the wick there is the-'toothed wheel K mounted upon a shaft Ly j ournaled in the housing L on the outer pe` riphery .of the casing A. The shaftk L is obliquely arranged so that the teeth of the wheel Kwhich project within the outer casingthrough a slot L2 `engage the sleeve I in the apertures J. At the outer end of the shaft L is a knob My for actuating the wheel K to raise and lower the wick. It will be noted that because ofthe helical arrangement of the perforations J the wick is given both ,a rotary and longitudinal ymovement turning theknob. A lever N is rotatively mounted upon the shaft L adjacent to the knob M and is provided with inturned edges N adapted to engage ratchet teeth M peiupherally'r V,arianged upon the inturned flange M2 ofthe knob. They lever is resilL iently held in engagement with the ratchet by a spring() sleeved upon the shaft and abutting the shoulders O while the inner end of the lever is inwardly bent atk N2 to 'the burner while, ifit/isdesired to remove the lvvickpthe lever is manually operable against the Aaction of the spring O `to release ythe teeth N from the ratchet notches M to permita full .upward movement. Also, by

rremoving. they thumb nut G, the member D forming the inner'guide for t-liewick may be easily removed thereby aiding greatly in` assembly and disassembly of the wick. The member D, however7` is positively` secured within the casing and is rproperly aligned therewith by the annular shoulders B2.

/ In assembling the wickin the burner it isplaced'in the annular chamber E so that the perforations J are aligned with the teeth of the wheel K and the knobM is turned counter .clockwise causing a. downward movement thereof. Because .of the arrangementof the ratchet teeth `M it is unneces- `sary tomanipuflate the .lever N for when the latter engages the. fixed stop IJ it simply rides over the teeth until the lower end of the sleeve I reaches the bottom of the recess B. The length of the wick is preferably such that at thisvpoint it is entirely within the annular chamber E but by turning the knob in the reverse direction until the lever again engages the fixed stop it is suiciently raised to be lighted. This arrangement permits of easy assembly of the wick by ja person not familiar with burner construction since it is only `necessary to turn the knob as far as it will go in one direc-tion and then turn it as far as it will go iu vthe other direction when the burner will be in condition for use.

What I vclaim as my invention is l. In a wick burner, the combination of an outer casing, an annular wick within said casing, and an inner guide for said wick removably clamped to said casing.
