JOHN C. LOVE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO W. LOVE, OF THE SAME PLACE.

Letters Patent No; 68,889, dated September 17, 1867.

IMPROVEMENT IN LAMP-BUBNERS TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. G. LOVE, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an improved Lamp-Burner; and I do hereby declare the following to beafull, clear, and exact description ofthe same. I

My invention consists of a lamp-burner, in which two wick-tubos'are used in connection with a case and with .a plate or domc," having butone opening in the same, the whole being constructed and arranged, as fully described hereafter, so that a thorough combustion of the gases may be efi'ected, and alight of=great brilliancy and illuminating power produced.

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 bad to the accompanying drawing, which forms a part of this specification, and in which I Figure 1 is an exterior view of my improved burner.

Figure 2, a vertical section on the line 12, fig. 1.

Figure 3, a vertical section on the line 3-4, fig. 2.

Figure 4,, a plan view of fig. 1; and

Figure 5, a sectional plan on the line 5-6, fig. 2.

To a screw-cap, A, which is constructed for attachment to any-of the usual oil-reservoirs or fountains, are secured two flat-wick tubes B B, which are parallel to and a short distanceapart from each other, and at the side of each tube turns a spindle, towhich are secured the usual serrated wheelsfor elevating and lowering the wick. The tubes 13 B above the cap A are surrounded by a cylindrical casing, C, which is open above andbelow,

and which is divided into three chambers 21 at x by vertical partitions a a, fig. 5, the chamber x including the i space between the wick-tubes. Onthe casing C slides a hand or cylinder, D, which is flanged at the upper edge, as shown in figs. 2 and 3, and near this edge are perforations c c, for a purpose described hereafter. At the upper edge of the cylinder D are flexible projections b Z within which lit an annular plate, 0, and a disk or dome, d, the latter having on the centre an oblong opening, 3/, the sides of which are parallel withthose of the wickrtubes B B.- The annular plate 1: is curved as shown in the drawing, and from the lower edge project two lips it, which extend into the chamber 2:, as shown in fig. 2. The burner is provided with an ordinary cylindrical glass chimney, which rcsts on the dome (l, and is confined in its placeby the elastic projections b. lhe flames from both wicks rise through the opening 3 in the plate d, and an upward current of air is created both in the chimney and in .the chambers re :1: 9:, the air also passingthrough the perforations e c, and being directed by the plate 0 against the flames just above the ends of the wicks. The partitions (to prevent the current of airwhich passes upward between the tubes 13 B from being drawn toward the outer sides of the tubes, while the lips z'z'prevent it from spreading laterally, so that it passes upwardsbetween the two flames,

which are thus furnished with sufiicient oxygen to insure a most thorough combustion of the gases. I have found by practical experiments that by the use of two wicks placed a short distance from each other, and the flames, from which pass through the same opening in a plate or-.dome above the ends of the wicks, the edges of which opening are parallel with the sides of the wick-tubes, a light is produced far surpassing in brilliancy that which could be obtained from the flames of two'lamps provided each with a single wick. It should be understood that it is indispensable that the edges of the opening in the dome shall be parallel with the sides of the wick-tubes, otherwise the size and brillianey of the Home would be greatly diminished.

A burner of the above description, besides being cheap and not liable to get out of order, maybe applied to any of the usual coal-oil lamps. In some instances the plate 0! maybe perforated, and may also extend over the chambers :c x to or nearly to the wick-tubes. The latter may also be slightly curved, if desired.

I am aware that lamps with two wick-tubes and a dome, with one opening above the tubes, have been here tofore made. I. therefore do not claim broadly such an arrangement; but I claim as my invention, and desire 1 to secure by Letters Patent 1. The wick-tubes B 13, arranged adjacent to eachother, in combination with a casing and with a dome or plate having a single opening through which the flames from both wicks may pass, and the edges of which are parallel to the sides of the wick-tubes, the whole being constructed and arranged as and for the purpose described.

2. The case C, with its partitions a a, in combination with the tubes B B and dome d, the whole being arz enged substantially as and for the purpose specified.

3. The combination of the above and the plate a and its lips z'z', arranged in respect to the openings a, substantially as set forth. l

Intes'timony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.

JOHN C. LOVE.
