LIGHTING ARRANGEMENT FOR OIL-STOVES.

Specification of Letters Patent.

Patented Jan. 23, 1917.

To all whom it may concern:

Be it known that I, HUBERT A. BARscHow, a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Lighting Arrangements for Oil-Stoves, of which the following is a specification.

My invention relates to improvements in means in an oil stove for elevating the combustion tubes from the burner bowl to. light the stove, for lowering the tubes to the burner after the stove has been lighted, and for properly reseating the tubes when lowered.

A further object of my invention is to provide means for maintaining the combustion tubes in an elevated position when the stove is to be lighted or is not in use, thereby pre venting oil from creeping up the tubes from the burner bowl.

In the accompanying drawings, Figure 1 is a vertical sectional view taken on line l1 of Fig. 2 of an embodiment of my invention. Fig. 2 is a front elevational view of the structure shown in Fig. 1, the combustion tubes being in elevated position. Fig. 3 is a plan view of the supporting and reseating member.

The inner and outer combustion tubes, des ignated by numerals 1 and 2, respectively, are connected together in any suitable manner, as by the crossed rods 3. The lower end of each combustion tube is adapted to be seated upon the burner bowl 5. The burner bowl comprises an annular trough 6 with outwardly-extending flanges 7, the latter.

having upwardly-extending guide portions or rims 8 adapted to retain the combustion tubes upon the flanges 7. Within the trough 6 is an incombustible absorbent lighting ring 9. The trough is suitably connected to a feed pipe 10 through a valve casing 11.

Extending across the opening in the annular burner bowl and carried thereby, are the braces 12, 13 and 14. The central portions of the single brace 12 and crossed brace 14 support and guide a vertical spindle 15 for rotational and longitudinal movement, the spindle being centrally located within the cylindrical burner. The spindle projects above the level of the burner bowl and bears at its upper end a spider 16 to which is suitably secureda circular rim member 17, the spider and rim being preferably integral and herein shown rigidly secured to the spindle. Extending above the level of the rim member is a spear-shaped head 18 integral or otherwise rigidly secured to the spindle.

To the inner wall of the inner combustion tube is suitably secured a horizontal perforated plate 19, having, at its center, an upwardly-extending convex portion 20 with a complementary opening 21 adapted to receive loosely the spear-shaped spindle head. The hole and spindle head are of such shape that rotation of the spindle will cause the combustion tubes to rotate. The rim member 17 lies beneath the horizontal plate 19, and when the spindle is raised or lowered, the combustion tubes are correspondingly elevated or lowered, since the plate 19 rests upon the circular rim at all times except when in the lowered position.

Beneath the brace 12 and below the level of the burner bowl, the spindle is bent horizontally to form a crank arm 22, said arm having a handle 23. The arm 22 may be bent as at 2 1 to clear the feed pipe 10. The handle 23 extends beyond the circumference of the burner bowl.

Suitably secured to the valve casing 11 or the base of the burner bowl is a horizontally-disposed lug 27 which is adapted to support the crank arm 22 when the tubes aretobe supported in the elevated position, as shown in Fig. 2. A lug 27 is herein shown at each side of the valve casing. When the crank arm 22 of the spindle is swung away from the lug 27, the combustion tubes may be lowered and seated on the flanges of the burner bowl. To insure proper, seating of the tubes within the upwardly-extending rims 8, the spindle may be partially rotated, whereby the tubes are rotated. upon the burner bowl and thus enabled to seat themselves within the rims 8 and upon the flanges 7.

With the structure herein disclosed it will be seen that the combustion tubes may be easily raised from the burner bowl in order that the lighting ring may be exposed and accessible. After the ring has been lighted the combustion tubes are lowered and then properly seated upon the burner bowl by partially rotating them.

I have herein shown and described my invention as applied to a blue-flame wickless oil burner, but it will be apparent that the invention may be applied to a wick oil burner with equal facility. Although I have described in considerable detail the embodiment herein disclosed, I would have it understood that the invention is limitedonly by the scope of the appended claims.

I claim as my invention:

1. A burner for an oil stove having, in combination, concentric combustion tubes, the inner tube having near the lower end thereof a horizontally disposed plate with a central opening, a burner bowl, a spindle carried by said bowl and adapted for rotational and longitudinal movement, a member supported by and rigid with said spindle and adapted to support said tubes while be ing elevated or lowered, a projecting head rigidly secured to said spindle, said head extending loosely through and cooperating with said central opening for rotatin said tubes, and a lug on said bowl structure and adapted to support said spindle when the latter and the tubes are in an elevated position.

2. A burner for an oil stove having, in combination, combustion tubes, a burner bowl, a spindle carried by said bowl for elevating 0r lowering said tubes, said spindle having a portion thereon adapted to support the tubes while being elevated or lowered, and said spindle further having a head for rotating said tubes, means on one of said tubes cooperating with said supporting means and head, and a lu secured to said bowl structure and adapted to support said spindle when the latter and the tubes are in an elevated position.

3. A burner for an oil stove having, in combination, concentric combustion tubes, the inner tube having near the lower end thereof a horiz0ntally-disposed plate with a central opening, a burner bowl, a spindle carried by said bowl and adapted for rotational and longitudinal movement, a member rigidly secured to said spindle and adapted to support said tubes while being elevated or lowered, and a projecting head rigidly secured to said spindle, said head extending through and cooperating with said central opening for rotating said tubes, whereby the tubes may be properly seated upon said burner bowl.

4. A burner for an oil stove having, in combination, concentric combustion tubes, the inner tube having near the lower end thereof a horizontally disposed plate with a central opening, a burner bowl having outwardly-extending flanges with upwardly projecting rims, and a spindle carried by said bowl and adapted for rotatable movement, said spindle having a head rigidly secured thereto, said head extending through and cooperating with said central opening whereby said tubes will be correctly seated upon said flanges and withinsaid rims when rotated by and with said spindle.

5. A burner for an oil stove having, in

combination, concentric combustion tubes, the inner tube having near the lower end thereof a horizontally-disposed plate with a central opening, a burner bowl, a spindle carried by said bowl and adapted for rotation, a member supported by said spindle and adapted to support said tubeswhile being rotated, and a projecting head rigidly secured to said spindle, said head extending through and cooperating with said central opening whereby said tubes and said supporting member may be rotated by and with said spindle.

In testimony whereof, I have hereunto set my hand.
