BURNER UNIT Charles L. Goli'mann, New Albany, vInd. Application July 22, 1935, Serial No.‘ 32,508‘ " \ ‘ " 1 Claim. This ‘invention relates to an oil burner unit j‘which is‘ primarily intended for use in the so- ‘icalled “family” oil burning cooking and heating ‘stoves, but which is generally useful for heating ‘Figure 7 ‘is a section along line 1-1 of Fig~ ‘ ure 5; , > 7 ~ ' , ‘ Figure 8 is an enlarged section along lineB-U of Fig. 6. , ‘ ‘ ' . a , 5 purposes. In devices of this character, oil is fed from a reservoir throughv valved pipes to an oil burner usually containingconcentric oil grooves ‘in which circular‘ band‘ wicks are placed. 1 ‘ J While these parts are variously arranged in 10 ‘different stoves, it is‘ believed that reference to the In accordance with my invention, all of the 5 burner unit parts, i. e., the reservoir, burner, ‘ valves and oil feed pipes, are mounted upon a base so that they maybe inserted into and‘ re moved from the heating chamber of the stove as a unit. The base may be constructed in any suit- 10 = able form and of any suitable material. As shown', it is of rectangular skeleton form, having angle iron side members‘l which are connected general and representative arrangements usually employed will serve to make the present inven‘tion more clear. In such arrangements, the stove ‘ ordinarily contains a burner chamber extending 15 from the front of the stove to its rear. Twin ‘ burners are suitably mounted in parallel or series "between the front and rear walls of the burner chamber. An oil pipe extends from the under 1 ‘side of each‘burn‘er forwardly to its valve adjacent together by spaced cross members 2 of T shape. At one end of the base, supporting legs 3 are 15 provided for an oil‘ sump 4. The sump is adapted to support at a suitable elevation‘ an inverted _ reservoir, 5. ‘ The reservoir, which is of a well known type, 2 O the front wall. An oil supply pipe extends from the ‘valves either rearwardly under one or both of the burners to a reservoir built in the rear 01' the stove, or, around the oven chamber of the stove to a reservoir on the other side thereof. has a valved outlet 6 which is held ‘closed by‘ a 20 suitable spring (see Figure 7) ‘until the reservoir is inverted andlpositioned upon the sump, where upon the valve stem strikes the bottom of the sump, thus opening the valve. When the valve 25 ‘With any of these arrangements, access to the various parts is limitedby the stove structure is opened, oil ?ows into the sump, ?lling it and its 25" outlet pipe 1, up to the flow regulating valves, while the oil feed lines are often subjected to a degree of heat sufficient to produce gasi?cation of oil therein. Both of these results are ‘objec30 tionable. ; . ~ ‘ The principal object of this invention is to ‘avoid these objections and, more particularly, to provide a simple, compact structure which does not require vattachment to the stove but 3; which, on the contrary, may be inserted into and ‘removed from the stove as a unit. ‘ (cries-44), until the oil level reached in the sump is higher than the lowermost portion of the reservoir valved outlet 6.

By the time the burner is hot enough to vaporize the oil in the troughs completely, the vaporizing chamber will be heated sufliciently to vaporize the oil as it enters. The burners 8 should be supported at a level such that oil from the reservoir will cease ?owing to the burners when the oil grooves in the burners are half full of oil. The burners should, of course, be properly leveled to produce a uniform depth of oil in the grooves, and such level may be ob tained by adjusting the level of the stove accord ingly. The burners may be directly supported on or secured to the base I. They preferably, how ever, are mounted on a platev H which is adjust ably secured to the base I through the agency of screws l8 threaded to the base and having means at their upper ends for holding the plate. When so mounted, ?nal adjustments of the burn er levels can be effected by the screws. The sump outlet oil pipe ‘I and burner supply oil pipe l2 are, of course, connected to each other through regulating valves and suitable piping. In accordance with previous practice, these valves would be provided with short valve stems and able openings in the front wall of the stove so that the valves may be regulated from the ex terior thereof. With the arrangement thus described, it will be appreciated that the amount of oil piping ex posed to the heat of the burner is reduced to a minimum. Hence, the possibility of oil being vaporized in such pipes is likewise reduced. ‘Such vaporization is highly undesirable because it pro duces an uneven and “spurting" flame. In some 10 instances, the pressure of the vaporized 011 causes it to spurt sufficiently to extinguish the ?ame. The reduction of exposed oil piping is, of course, accomplished by placing the valves adjacent the reservoir while convenient access for regulating 15 the valves is maintained by providing them with long valve stems. It will also be appreciated that the structure herein described is very sturdy and compact and one which can be readily in serted within a heating chamber of .su?lclent size _ to receive it. When any parts require adjustment or repair, such parts are, by virtueof the uni tary and removable structure herein proposed, readily accessible. located on the stove adjacent the front wall Having described my invention, I claim:A portable oil burner unit of the type intended for insertion into and, removal from the heating thereof or on a stand which is set apart from the stove.
