Letters Patent N 0. 98,264, dated December 28, 1869.

IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters'Patent and makingpart of the .same.

To all whom it may concern.

Be it known .that I, Jons Homomof the city, county, and State of New York, have invented a new and improved Lamp; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ac companying drawings, and to the letters of reference marked thereon, making a part of this specification. 7

This invention relates to a new and improved lamp, applicable, chiefly, to what is generally termed and known as theargand burner, and which is prcvided with an elevated fountain or reservoir, to supply the flame with oil under static pressure.

My invention consists in a certain modification in the construction of the drip-cup of suchburners, as hereinafter fully shown and described, whereby the wick may be light-ed, by introducing a taper or torch up into and through the body of the burner from the underside of the same, so that the necessity of removing the glass chimney and shade, is entirely obviated.

My invention also consists in providing a convenient place in the lamp, for the reception of the taper or torch, when not in use, and, also, in the applicacation to the lamp, of a matchbox, all of which parts, with their construction and advantages will be hereinafte-r set forth.

The accompanying drawing represents a side sectional elevation of my invention.

A represents the base, which supports the lamp, and Bis a rod, securely fixed centrally in the base, on which rod the tubular arm 0 is allowed to slide freely up and down, so that it maybe secured at'anydesired point on the rod, by a set-screw.

One end of this arm 0 is connected to and communicates with the oil-fountain or reservoir B, andthe opposite endis attached to and communicates with the burner-E, which is constructed on the Argand principle.

The arm 0 is so curved or bent, or the fountain or reservoir has such an elevation, that the oil within the latter will be fed to the lamp-wick until the fountain or reservoir is entirely empty.

The burner E is. composed of an outer cylindrical shell, (I, having within it a concentric tube, 1), permanently secured at its lower end to the bottom of shell a, the tube 1) being sutiicientlysmaller than a, to admit of a requisite space between a and b, to form an oil-supply chamber for the wick c, which encompases tube I), the former wick cbeing attached at its lower end to a thimble, d, which is fitted on tube 11, and has a spiral slot cut in it, to form a lip, 11, to fit into a sunken screw-thread, f, on I).

The thimble d is provided with a lateral projection, which passcs'into a vertical slot, made in a tube, '5, attached permanently to the upper portion j of the burner, the tube a, passing down into the chamber or space between a and Zr, and provided with holes, to admit of the oil coming in contact with the wick.

By turning the top j of the burner, the wickis raised and lowered, to regulate the height of the flame.

.The parts above described are old, and, therefore, do not comprise a part of thls iuvention, but are merely described or set forth, to show clearly the character of the parts hereinafter named, and coasttuting my invention.

F represents the drip-cup, designed to receive the overflow of oil from the 'tops ofthe tubes b and 11, This drip-cup is perforated with holes I, at its top, all

around near its edge, and it is screwed upon'the lower end of shell a, so as to receive all drip from the earterior of a, and, also, all that which passes down within l), the oil which passes down within the latter following, of course, the sides of the same. I

Within the drip cup F there is a fixed tube, m, open at the top and bottom, and having its lower orifice through the centre of the bottom of the cup. This tube at extends upward a short distance above the level of the top of the cup, and within tube 1), as clearly shown in the drawing, and is suiiiciently smaller in diameter than I), to avoid the drip that passes down the inner side of I).

The tube at is one of the principal features of my invention, and admits of important results being attained, to wit, a taper or torch may be inserted up through the tube on, into and above the top of the wick 0, so that the latter may be lighted, without removing theglass chimney and shade, and further admits, in case the cup F becomes filled with oil up to the holes I, of a requisite supply of oxygen, passing up through m, to supply the flame.

The ordinary drip-cup, having no central tube at, the flame is dependent for its supply of oxygen through the holes I, and in the event of the latter being out off or sealed by an excess of oil in the cup, a not uncommon contingency, the smoking of the flame is an inevitable result.

The taper or torch, designated by G, when not in use, is inserted in the 'upper part of the rod B, the upper part of B, being tubular, to admit of that result, as shown in the drawing. place for it, and it may be very readily drawn out for use, and readily inserted after use. I

To the side of the fountain or reservoir D, there is attached a match-box, H, to hold the matches for lighting the taper or torch.

Having thus described my invention,

This is a very convenient What I claim as new, and desire to secure by Let ters Patent, is-- v 1. Providing the drip-cup F of an, argand burner with the vertical central tube in, in the manner substantially as and for the purpose set forth.

2. The torch or taper G, inserted in the rod B of the lamp, when the former is used with or applied to 'an argand-bnrner lamp, having the drip-cup F of its burner provided with a central tube, m, substantially as shown and described.

3. The match-box H, taper or torch G, fountain or reservoir D, and the argand burner E, when all are constructed, combined, and arranged to form a lamp andconvenient lighting-apparatus, substantially as herein shown and described.

The above specification of my invention signed by me, this 6th day of November, 1869.

JOHN HORTON.
