JOHN LAWSON AND MATTHEW LAWSON, OF SWALWELL, ENGLAND.
BURNER FOR OIL-LAMPS.
Specification of Letters Patent.
Patented Aug. 18, 1908.
Original application filed March 16, 1907, Serial No. 362,622. Divided and this application filed March 13, 1908. Serial No. 420,887.
To all whom it may concern:
Be it known that we, JOHN LAWSON and l\/IATTHEW LAWSON, subjects of the King of England, residing at Marley Hill, Swalwell, in the county of Durham, England, have invented certain new and useful Improvements in Burners for Oil-Lamps, of which the following is a specification.
This invention relates to improvements in burners for lamps burning mineral or other oils and is applicable to all lamps with flat wicks, such as miners safety lamps, hand lamps, carriage lamps, house lamps and the like, in which at the upper end of the flat wick-tube, the narrow sides are slotted and the broad sides are bent outwardly, and consists in forming such outwardly bent broad sides with a perforated extension or with equivalent attachments designed to admit an additional supply of air to the flame for the purpose of increasing its size and intensity. To form such extension a plate may be soldered on each outer face of the broad sides of the wick tube, the plate having a suitable number of orifices or perforations in its upper part arranged to project above the upper edge of the wick tube.
In a further construction a sleeve is arranged to fit over the wick tube and perforated in the part projecting above the upper edge of said tube. This sleeve may either be soldered to the tube, or arranged so that it can be raised or lowered by any suitable means to a certain extent so as to regulate the air admission for different grades or kinds of oil; or the broad sides of the wick tube may be extended upwards and perforations provided in the extended. parts.
The accompanying drawing illustrates various forms of the invention applicable to different types of lamps.
Figures 1 and 2 illustrate the form of the invention in which a plate is soldered to the side of the wick tube, Fig. 1 being a sectional elevation and Fig. 2 a side view with parts omitted. Figs. 3 and 4 are similar views of the form of the invention in which the perforated plate is movable. Figs. 5 and 6 are similar views of the form of the invention in which the wick tube has perforated extensions integral therewith.
In Figs. 1 and 2 the wick tube it carried by the plate 9 is provided at the upper extremity of each of its narrow sides with a slot or opening 1) extending downwards for a certain distance, and has the upper edges of its broad sides bent somewhat outwards making the upper ends of the slots wider as shown in Fig 2.
To the exterior face of each broad side of the wick tube a plate d having perforations e is attached, the upper ends projecting above the top edge of the wick tube. By this arrangement air can freely pass through the slots I) and orifices e causing a better combustion than hitherto.
Figs. 3 and 4 illustrate a form of construction in which the plates 61 are carried by a sleeve f surrounding the wick tube a and are provided with elongated apertures 6 The said sleeve may be fixed or adapted to be moved upwards or downwards by any suitable means so that the apertures 6 can project more or less above the sides of the wick tube and the amount of air passing through the apertures a can thus be regulated at will.
Figs. 5 and 6 illustrate the form of construction in which the broad sides of the wick tube a are bent outwards so as to form the slots 6 and are then extended vertically upwards, orifices a being provided in the extended portions for the passage of the air.
- What we claim as our invention and desire to secure by Letters Patent of the United States is:
1. In an oil lamp burner the combination with a wick tube, having its narrow sides slotted and its broad sides formed with straight parallel portions and outwardly flared portions, of parallel perforated extensions forming continuations of said flared portions and lying in planes parallel to said straight portions.
2. In an oil lamp burner the combination with a wick tube having its narrow sides slotted and its broad sides flared outwardly,
of parallel perforated extensions forming continuations of said broad sides and in contact with the outwardly flared portions thereof.
3. In an oil lamp burner the combination with a wick tube having its narrow sides slotted and its broad sides outwardly flared, of adjustable and parallel perforated extensions forming oontinuations of the outwardly flared portions of said broad sides and in con- 10 tact with said flared portions.
In Witness whereof we have signed this specification in the resence of two witnesses.
