Application led September 25, 1918. Serial No. 255,677.

To all whom t may concern Be it known that I, ROBERT PERLICK, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention is directed to new and useful improvements in oil burners of that type wherein oil is supplied to a burner member including a fuel trough having disposed therein a relatively stationary incombustible wick body of asbestos or the like, and having a depending tube slidable in a supply pipe, the regulation of the flame being procured by raising and lowering the burner bodily to thus vary its relation to the fuel supply level, and my invention relates more particularly to means for procuring movement of the burner member.

It is in general my object to simplifyand otherwise improve the structure and to increase the efficiency of devices of this character.

It is more particularly my object to provide a burner operating mechanism which may be constructed mainly of stamped sheet metal and retained in place by its interlocking engagement with the main supply pipe and burner branch of a stove.

A further object resides in the provision of means for adjusting the'cap of a packing gland for the burner tube and supply pipe, whereby the cap is normally held against threading movement, and may be readily tightened.

With the above and other objects and advantages in View, which will be apparent as the description proceeds, my invention resides in the novel features of construct-ion, combination and arrangement of parts as hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

Figure 1 is a vertical sectional view through an oil burner stove having my'improved operating mechanism associated with the burners.

Fig. 2 is a front elevational view of the stove.

Fig. 3 is a rear view of one of my improved burner operating -mechanisms, the burner operated thereby being shown insection.

Fig. 4 is a side View of the mechanism, with portions thereof in section.

Fig. 5 is a plan view of the supporting bracket and associated portions of the mechanism.

Fi 6 is a front elevation of the control hand e and indicator dial,

rReferrin now more particularly to the accompanying drawings, there is shown an oil burning stove including a main burner chamber A'having a grid a and having disposed under the grid a series of burners C projecting into hoods D of conventional nature interposed between the burners and grid. A main supply pipe E extends from the fluid level chamber f of a reservoir F disposed at one end of the stove. The constant level chamber is provided in the usual manner with a valved neck portion conventionally designated at g in Fig. 3, Wherebya constant level line L may be maintained in such relation to the burners C that the bottom portion of the burners may be moved to lie either above or below thislevel line, the main supply pipe E being extended longitudinally in the main burner chamber A below the level line and being provided with upstanding supply pipe branches e located in a vertical plane at the forward sides of the burners C, said burners being in the form of annular narrow troughs having their side walls slightly divergent upward for wedging insertion therebetween of an annular wick band 0 formed of asbestos or similar non-combustible porous material. Each of the burners is supplied with oi-l' and is supported solely by a depending stem, c which is telescopically slidable in a corresponding supply pipe branch e, the degree -of sliding movement of the stem permitting the lower portion of the burner to move pastl the fluid level line L. A `packing gland for the stem is provided including a cap c2' threaded on the upper end portion of the supply pipe branch and confining packing material between the top of the cap and the end of the pipe branch', said cap being provided with Wrench faces, whereby the gland may be tightened as desired incidental to yielding of the packing material in continued operation of the burner.

My improvedmechanism for raising and lowering each burner to control vthe feed of oil through the wick includes a bracket formed of a sintgle plate of metal intermediately bent to orm a horizontally extending arm 10 and a vertically extending arm l1, the inner end portion of the arm 10 belng apertured to snugly receive the supply pipe branch e. The vertical arm 11 has its lower portion bent laterally forward and then downwardly to provide a shoulder 12 resting on the main supply pipe E, and a substantially vertical portion 13 disposed forwardly of and projecting below the pipe. Struck outwardly from the intermediate portion of the bracket arm 11 and bent vdownwardly below the shoulder is a tongue 14, the main supply pipe E being confined between the tongue 14 and arm end portion 13. Upward displacement of the bracket is prevented by a cotter pin 15 passed through the arm portion 13 and the tongue 14 below the pipe, and thus the bracket is firmly secured to the supply pipe structure in a 'manner permitting a maximum economy in forming the bracket, and a minimum expenditure of labor in assembling the bracket on the supply pipe and branch, the major securement of the bracket being procured simply by the interlocking relations assumed in inserting the supply pipe branch in the apertures of the arms 10 and 11 of the bracket. The forward end of the horizontal bracket arm is downwardly directed at 16 to form an attaching flange to which is secured the lower portion of a vertical dial plate 17.

This downwardly turned bracket arm portion, in conjunction with the lower portion of the dial plate is also utilized to form the journal for the forward end of an operating shaft 18 which extends under the bracket arm at one side of the supply pipe branch e and has a second journal in the upper portion of the vertical arm 11 of the bracket. Immediately rearwardly of the arm 11 this shaft is squared for the recept-ion of the headed end of a crank arm 19, the extremity of the shaft being swaged at 20 in Fig. 3 to secure the crank arm on the shaft. Pivoted to the extremity of the crank arm is a link 21 which is also pivoted to the up-turned free end of a lug A22 projecting inwardly from the lower portion of the burner at its juncture with the supporting and supply tube c. Thus, upon rotating the shaft18, the burner C may be raised or lowered so that its bottom portion is disposed either above or below the Huid line L. To procure this rotation of the shaft, and at the same time procure indication of the position of the burner relative to the fluid level line, the end portion of the shaft outwardly of the dialplate 17 is directed obliquely, and a bar 23 is riveted at an intermediate portion to this oblique end of the shaft, the major portion of the bar extending downwardly to form a handle. The remaining portion of the bar being inclined toward the dial by reason of the attaching portion of the shaft, forms an indicator cooperating with certain symbols on the dial, the handle being spaced forwardly by reason of this oblique inclination to permit a most ready and convenient manipulation thereof.

To hold the shaft 18 against longitudinal movement, and also to provide a support for a leaf spring 24 engageable with the head of the link 19, la vertical plate 25 is secured to the sideof the bracket adjacent the shaft by `the attachment of its laterally turned upper end 26 to the horizontal arm of the bracket, said plate extending rearwardly of 'the bracket and being provided in its rearward portion with a vertically elongated slot receiving the head of the link 19, the engagement of said head in. the' slot obviously preventing longitudinal movement of the shaft 18 to which it is attached. The leaf spring 24 is secured at its lower end to the lower rear portion of the plate and bears against that portion of the head which projects through the slot, the head having its periphery rounded concentric with the shaft, whereby a frictional detent is afforded by the spring in the various rotative positions of the shaft, and to hold the burner more positively in normal burning position, and at the same time aid the operator. in attaining this normal burning position, the head of the link is provided with a notch 27 in which the transversely bowed free extremity .'-of the spring engages when the link 19 is disposed in a substantially horizontal position, procuring a position of the burner intermediate of its limits of vertical movements, the lower edge of the wick being disposed slightly below the' fluid level line. L in. this position.

It is noted that the link may swing through an are of substantially 1800,' engaging in either limit of movement against the rearward portion of the wall plate 25, and in its upward limit of movement, it is noted that the upper end of the lin-k swings for abutment with the plate, slightly past a dead center line connecting the axis of the shaft 18 with the pivotal axis of the burner lug 22, whereby the burner is thus locked in raised position.

The indicator dial 17 is provided with symbols 28 and 29 at opposite sides of the shaft 18 indicating respectively the upper and lower limits of movement imparted to the burner by the handle and indicator bar 23, the burner being raised to its limit of upward movement, consequently cutting otl' supply of oil thereto when the indicator points to-the symbol 29, and being depressed to its lower limit of movement when the iudicator points to the symbol 28 to supply an excess of oil to the burner to facilitate lighting the burner. Intermediate of the symbols 28 and 29 there are provided a series of renacer Continued raislng and lowering move.

ments of the burners loosens the packing glands of the supporting tube c, and it is necessary from time to time to tighten the gland caps o2, to take up thislooseness. l provide a tightening means for the cap in a most compact and readily operated mannen which means is associated permanently with the burner structure as is necessary in a commerciallyattractive article. Thus, a wrench is provided including an annular closed head 3l apertured to receive the cap, this wrench head being provided with upwardly and inwardly extending lingers 32 adapted to seat l on the cap. A downwardly olset handle 32 extends from the wrench head and is provided with a slot 33 which normally receives a finger 34 struck upwardly from the horizontal arm 10 of the bracket, whereby a lock for the cap is normally afforded preventing any tendency to unscrewing movement which would be set up in operation ofthe burner. To tighten the cap c2, itis merely necessary to lift the wrench handle 32 from engagement of the finger 3l in its slot 33, and then to rotate the' wrench and cap, the wrench being subsequently engaged with other wrench faces of the cap and restored to its locking co-action with the finger 84.

An. exceedingly simple device has thus been provided for tightening the cap which Vmay be readily manipulated by persons not necessarily familiar with mechanical operations, it being noted that a maximum coinpactness of structure is permitted incontradistinction to heretofore contemplated arrangements. Attention is further directed to the fact that loss of the wrench is positively prevented by reason of the closed shape of its head, so that the head is interlocked at all times either on the cap 0r with respect to the tube ,0.

1t w1ll be particularly noted that by the disposition ofthe suppl tube c and the connecting link 21 at the orward side portion of the burner C, the c'enter of gravity of the burner isdisposed a considerable distance laterally thereof, and thus a frictional binding action is set up which normally holds the burner against downward movement under influence of gravity, this holding being relied upon to maint'ain the burner in its various burning ositions other than the intermediate norma burning position in which the spring 24 engages in the notch 27 of the head lof the crank arm i9, said spring also, of course exerting some frictional actionagainst the periphery of the head when disengaged from the notch.
