BURNER.

SPECIFICATION forming part of Letters Patent No. 720,466, dated February 10, 1903.

Application iiled March 14, 1902. Serial No. 981142. (No model.)

To all whom t may concern:

Be it known that I, HAZEN OBERLIN, acitizen of the United States, residing at Jamaica Plain, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvementin Burners, of which the'following is a full, clear, and exact description.

The obJl ect of this invention is the construction of an improved attachment by means of which an ordinary kerosene-burner shall have its power of illumination considerably augmented, shall have a malodorous emission of vapor wholly prevented, shall have its liability to explosions eliminated, and the iiam'e of which shall be instantly extinguished by simply turning down the wick.

Referring to the drawings forming part of this specification, Figure lis a side elevation of an ordinary kerosene-burner having my attachment applied thereto, the upper portion of the burner being represented as broken away in order to show the attachment. Fig. 2 is a plan view of the attachment laid flat. Fig. 3 is a side view of the attachment, and Fig. 4 of an inserting device.

Said attachment consists of a thin narrow metal plate l, having a longitudinal slot2 therein, corresponding in dimensions to the wick-tube 13. Preferably this plate is about three times the width of said slot and is substantially equal in length to the diameter of the burner dome or deflector ll, such proportions causing that the width of metal inclosing the slot 2 shall be approximately equal to the width of the said slot. This plate l is designed to be secured to the burner-walls slightly above the upper end of the wick-tube 13, the difference being preferably not far from a sixteenth of an inch and the slot 2 lbeing in alinement with the wick-tube. The

' mately bent outward through the slot in the dome 1l and so fasten the plate in place.

To accurately place the attachment, I swing the upper part of the burner 10 away from thelower or base section on the hinge l5, with which such burners are formed. I then drop the attachment into the dome, with the ears 4 entering the slot in said dome, the attachment being now inthe shape shown in Fig. 3. Next a jig or guide isinserted within the wick-tube, the same comprising a plug 22, fitting somewhat closely the interior of the wick-tube and having a shoulder 20 resting upon the upper end of the tube. The dome 1l is now turned back down upon its base-section and the plate 1 fitted about the upper end 2l ofthe guide and upon the shoulder 20. The ears 4 being bent outwardly to the position shown in Fig. l, while the bases of the shoulder-sections 5 press outwardly beneath the shoulders l2 of the dome, the plate l is firmly secured in position with its slot'alining with the wick-tube and itself at the proper distance above the same. The dome-section of the burner can now be swung open again and the guide removed, leaving the burner in condition for use. v

In addition to the function above described-that of fastening plate l in placethe ears 4 perform the work of spreading the flame arising from the wick, andk thereby so increasing the area of the same as to materially augment its illuminating power. The reason for this spreading of the dame is that said ears or spreaders 4 not only prevent the air from rushing in through the lower ends of the slot in the dome 1l, but act to force outwardly the uprushing currents and so carry with thelatter the edges of the flame to a kfarther distance from the burner, thereby widening and spreading the iiame.

What I claim as my invention, and for which I desire Letters Patent, is as follows, to wit:

l. The combination with the burner having the usual flame-slot in its dome, of the plate having the slot coinciding with the wick-tube and the ears bent up from its edges at substantially right angles with itsv surface, and each ear bent at an intermediate point out through an end ofthe flame-slot, substantially as described.

2. The combination with the burner having the usual flame-slot in its dome, of the plate IOO having the slot coinciding with the wick-tube In testimony that I claim the foregoing in- -find the ears bent from its edges at substfmventon Ihzwe hereunto set my hand this 12th tially right angles with its face, and eaeh ear day of March, 1902.
