Laim Patent No. 75,697, am.: March 1r, 186s.
vIhIPIiOiTEhLTSltil IN LAMP-BURNEBS.
TO ALL WHOM IT MAY CONCERN:
Be it known thatv I, R. W. PARK, of Philadelphia, Pennsylvania, have invented certain Improvements in Coal-Oil Lamps; and I do'hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to certain improvements, fully described hereafter, in the burners of coal-oil lamps, my improvements being such that the ame is contracted, but increased inheight and brilliancy, a plain cylindrieal chimney being used in place of the more expensive and fragile swelled chimney.
In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a vertical section of my improved coal-oil lamp, and
Figure 2 ahsectional plan view on the line 1-2, iig. 1.
A is a perforated casing, to the lower end of which is secured the wick-tube B, the casing having the usual screw-projection e for attaching the burner to the fountain or reservoir of the lamp. The casing A terminates at the top in a projecting iiange,f, through which pass, and to which are secured, the two air-tubes a a. The vdome D and plate E, for supporting the chimney F, are made in one piece, a recess being formed beneath the plate for the reception of a portion of the angefof the perforated casing A. Different modes may, however, be employed, of so fitting the plateE to' thesad easing that the former may be readily detached from thc latter. The two ar-tubes a a pass through openings in the plate E, and are so arranged that one tube is adjacent to one end, and the other to the opposite end, of the usual elongated slot in the dome, as seen in iig. 2. '.l'hese air-tubes, instead of being secured to the ilangefof the perforated casing, may be secured to the dome-plate E, care being taken, however, for the free admission of air to the tubes from below. The effect ofthe two currents of air is to contract the dame and increase its height and brilliancy, the flame having parallel sides, as shown by the dotted lines a: z, instead of the usual wide flame ot' limited height, as shown by the dotted lilies y y. This enables me to substitute for the eumbrons swell-chambcre'd glass chimneya cylindrical chimney, F, which is cheaper than, and not so liablo to become broken as, the swelled chimney. The currents of air from the tubes a a, intervening between the edges of the flame and interior of the chimney, maintain the latter in a comparatively cool state.`
In place of the air-tubes, simple openings may be made in tho plate E, and corresponding openings in the angef of the perforated casing A, for admitting air from below at. such points that it will pass upward in two currents, one near one end and the other near the opposite end of the elongated slot in the dome. I prefer the 'use ofthe air-tubes, however, as they insure more certain and defined currents of air directed to the proper points.
Bymakingthe dome and plate for holding the chimney in ono piece, and making the whole detachable from the perforated casing, as described, ready access may be had to the wick when it. has` to be trimmed.
I claim as my invention, and desire to secure. by Letters Patent- 1. In combination with the dome of a coal-oil lamp, two air-tubes, channels, or orifices, arranged, in respect to the elongated slot of the dome, substantially as set forth. I
The combination of the perforated casing A, plate E, dome D, and air-tubesa a, the whole being arranged substantially as described.
In testimony whereof, I have signed my name to this specification in the presence of two'subscribing witnesses.
R. W. PARK.
