This invention relates to oil burners, and more particularly to an improved means for starting or lighting an oil burner.

An object of this invention is to provide in combination with an oil burner of the wick type, an improved means in association with the burner for lighting the main wick.

Another object of this invention is to provide, in an oil burner provided with an annular wick, a pilot light and mounting therefor which is adapted to be constantly lighted so as to facilitate the lighting of the main wick.

At the present time in the use of certain oil burners embodying a circular or cylindrical wick, it is the practice of users to leave the burner constantly lighted due to the difliculty at present encountered in properly lighting the burner. is, therefore, a further object of this invention to provide a means whereby the main burner may be turned off and. a supplemental burner be provided in a position where it will promptly light up the main wick or burner, thus saving a considerable amount of fuel which is, at present, used in maintaining the main burner lighted at all times.

A further object of this invention is to provide, in a burner of this type, a means for vaporizing the fuel used by the main burner, the vaporization being efiected through the use of a pilot light positioned within the combustion zone of the main burner.

A still further object of this invention is to provide a pilot structure of this kind in the form of an attachment which may be mounted on the present structure of an oil burner so as to provide for instant lighting of the main burner by turning on the fuel valve leading to the main burner.

A further object of this invention is to provide a device of this kind which is exceedingly simple i construction so that it may be manufactured at a relatively small cost and may be mounted on the present structure of an oil burner without disturbing the present parts of the burner.

To the foregoing objects and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawings wherein is shown an embodiment of this invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention, as claimed.

In the drawings:

Figure 6 is a perspective view of the pilot burner casing removed from the main burner.

Referring to the drawings the numeral Ill designates generally a fuel reservoir which is mounted. on a standard ll supported on a base IS. The oil burner structure, generally desig nated as i2, is connected by means of a fuel supply line Hi to the reservoir ill. The burner I2 is adapted to be mounted in a suitable casing or jacket and is adapted to be positioned beneath a cooking top or grate on which articles are adapted to be positioned. The pipe line it is provided with a valve member I5 which is adapted to control the quantity of fuel passing through the line It from the reservoir it to the burner l2.

The burner i2 comprises a base plate l6 provided with a pair of spaced coaxially arranged cylindrical walls I"! and i8 coacting with a part of said base plate to form a well Ill. The latter is of U-shaped form in vertical section.

The supply line It includes a vertically disposed pipe 29 at its outer end and said pipe 20 is connected to the other portion of said line by an L-coupling ii. The pipe 28 extends up through the center of the base plate It to slightly above the latter. The upper end of the pipe 20 is surrounded in spaced relation by the wall I8. A plurality of radially disposed ducts 22 are arranged over the base plate l6 having the major portion of their length surrounded by the body of wall it. The outer ends of the ducts 22 are mounted in the body of the wall l8 and open into the well l9. The inner ends of the ducts 22 are connected to and open into a cap-like apertured coupling member 23 mounted on the upper end of pipe 29. In this manner the fuel from the supply line M is discharged into the well 1-9 at circumferentially spaced apart points within the well IS. A wick 24 is mounted within the well [9 and the upper end of the wick 2 3 projects slightly above the upper ends of the cylindrical walls I! and i8. An outer upstanding perforate shell 25, of substantially cylindrical construction, is mounted interiorly of the outer wall l1, and an inner upstanding perforate shell 26 engages against the inner surface of the inner wall 18 and is positioned in spaced relation to the outer shell 25. The shell 26 is of less height than the shell 25. The said shells have aligned parts of their portions cutout to provide a clearance for a purpose to be referred to. The cutouts open at the bottom edges of the shells. The said bottom edges are seated on the base plate H5. The shells are coaxially arranged. The wick 24 is positioned between the two shells 25 and 5- An apertured top plate 21 is secured to the upper end of the inner wall 26 and is provided with a projecting portion 28 which projects outwardly in the direction towards'the outer shell 25. The

outer edge of the projection portion 28 terminates in inwardly spaced relation to the outer shell 25 so that a space 29 is formed through which the flame or heat is adapted to pass.

At the present time in the use of the burner structure hereinbefore described, the lighting of the wick 24 is difficult or inconvenient and for this reason it is the general practice of users of this type of burner to leave the wick 24 constantly lighted. This will, of course, consume a considerable amount of fuel and in order, therefore to provide a means whereby the main wick 24 may be turned off I have provided a pilot structure which is adapted to be mounted within the well i9. 30 is mounted within the well I?! being of a width and height to readily engage between the two Walls H and is. This supplemental or pilot well 36 is formed of side walls 3!, end Walls 32 and a bottom wall 33. If desired, a top wall 34 may be mounted on the upper ends of the side and end walls 3! and 32 respectively and a pilot wick 35 is adapted to be positioned within the interior of the pilot well 32 and project slightly above the top of the top wall M. The pilot well 30 is provided with a threaded tube 36 which is secured to the bottom wall 33 and this tube 36 is adapted to project downwardly through an opening 3? provided in the base iii. The lower end of the pipe 26 terminates in a tapered portion 33 which is adapted to project within the flared portion 39 of a pilot supply pipe at. A

nut cl, provided with a head 42, is threaded onto the pipe 33 and the head or flange 42 thereof is adapted to abut against the bottom of the base plate it so as to tightly secure the pilot reservoir 3i] within the well l9. cap 53 provided with a central opening 44 engages about the pipe t and is threaded onto the nut or clamping member ll and serves as a means for tightly holding or coupling the flared portion 39 of the pipe Ml onto the tapered end 38 of the pipe 35. In this manner a pipe connection will be formed between the pipe 36 and the pilot supply pipe The lower end of the pipe id is connected to a short length of pipe it provided with a boss re. The pipe 29 is threaded into the boss 26. The pipe 45 is provided at one end, thereof with a cap LE-i closing the end of the pipe 55 and the other end of the pipe 35 is connected to a supply pipe 48 by means of a coupling member 29. The coupling member 29 is constructed in the form ofa cap which is threaded onto the opposite end of the pipe i and the pipe 48 is provided with a flanged portion 50 engaging between the head 5! of the cap 39 and the adjacent end of A coupling member or A casing or supplemental Well I iii the pipe 25. The pipe 48, as shown in Figure l, 75

voir 30.

is connected to the main supply pipe [4, between the valve l5 and the reservoir It by means of a nipple 52 which is connected at one end to an L 53 mounted on the pipe 48. The opposite end of the nipple 52 is connected to a T-connection 54 which is interposed in the pipe M between the valve i5 and the reservoir lil.

Preferably the pilot reservoir 39 is mounted between the pair of parallel walls 55 which are formed integral with the outer and inner walls I! and I8 of the well l9 so that the fuel entering the Well l9 will not leak out through the opening 31 formed in the bottom It and through which the pipe 36 of the pilot reservoir 30 extends. As shown in Figure 2, the wick 24 is split at the point where the walls 55 project between the walls I! and I8 and the flame from the pilot wick 35 is adapted to rise upwardly between the two perforated shells and 26. The cut-outs in the lower portion of said shells provide clearances for the walls 55 and the pilot reservoir when the shells are extended into the well l9 and are seated on the base plate 16. The wick is of sufficient size so that the heat generated by the lighting of the wick 35 will be sufiicient to vaporize the fuel contained in the wick 24.

In the use and operation of this burner and pilot attachment the burner I2 is connected to the supply reservoir in by the pipe 14 with the valve [5 interposed in the pipe 14. The pipe 48 is connected to the pipe M at a point between the valve l5 and the reservoir In so that the operation of the valve l5 will not affect the flow of fuel through the pipe 48 to the pilot reser- The wick 35 is initially lighted by removing the outer shell 25 and then replacing the shell 25. When it is desired to operate the main burner wick 24 it is only necessary to turn on the main valve i5 to the desired degree so as to permit th fuel to flow from the reservoir l0 through the pipe i4, ducts 22 and into the well 19 where the fuel will soak into the wick 24. As soon as the fuel contacts with the wick 24 the wick 2 4 will light up due to the fact that the flame from the pilot wick 35 will cause sufficient heat to be generated between the two shells 25 and 26 to effect substantially immediate lighting of the wick 24. Where desired the pilot reservoir 30 may be used in the form of an attachment to be mounted in the present structure of an oil burner, but when this is done the walls will be dispensed with.

The use of the burner starter or pilot structure hereinbefore described will effect a very considerable saving in the amount of fuel which is at present wasted by maintaining the burner l2 constantly lighted'due to the difiiculty of initially lighting the burner.

What I claim is:

1. In an oil burner, a horizontally disposed circular base plate having an axially arranged opening, uniformly spaced inner and outer upstanding coaxially arranged annular members integral at their bottoms with the upper face of said plate, a pair of spaced parallel upstanding elements arranged between and integral with portions of the inner faces of said members, opposed portions of said members coacting with a part of said base and the said elements to provide a well of U-shaped cross section for the reception of a wick of a height greater than the depth of the well, said well being formed of a pair of sidewalls, a pair of end walls and a bottom wall, the other opposedportions of said memof said shells being seated on portions of the 2';

bottom wall of said well, bearing against portions of the inner surfaces of said members, against a side face of said elements and upon the pilot means in said chamber, said cutouts forming a clearance for said elements, an oil supply line extending upwardly through said axial opening having its upper end surrounded in spaced relation by said inner member, radially disposed ducts positioned above said base having their outer ends arranged in the body of said inner member and opening into said well, a hollow cap on the upper end of said supply line formed with spaced apertures, said ducts having their inner ends connected to the walls of the apertures in and communicating with said cap, and an oil supply means for the pilot means extending from said supply line and up through said eccentric opening into said chamber.
