SPECIFICATION forming part of LettersiPatent N 0. 548,314, dated October 22, 1895.

Application tiled September 15, 1891. Serial No. 405,745. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM M. HOERLE, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Lamps; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to lamps, and more down to the lower outlet thereof, the result being that the table or support for the lamp will receive all such drippings.

The object of my invention is to improve the construction of the lamp in this and other respects, as willmore fully hereinafter appear. I

To these ends my invention consists, generally stated, in a lamp having the upper edge of its wick-tube provided with an internally and downwardly projecting lip and a tube within said wick-tube whereby any drippings will fall from the wick over said internally and downwardly projecting lip to the space between said tubes, thus providing-a way of escape for such drippings back into the fount of the lamp.

It further consists in certain other improvements and combinations of parts, all of which will be more fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure l is a central sectional view showing my invention. Fig. 2 is an enlarged detail View. Fig. 3 is an enlarged View of the flamespreader; and Fig. 4 is an enlarged view of the perforated truncated cone.

The lamp a consists of the fountor bowl I), having the central draft-tube csecured therein, the bottom of said fount being supplied with suitable air-entrances for the passage of central draft-tube 0 consists of the two portions 0' 0 the lower portion extending up to the shoulder 0 where the diameter ofsaid draft-tube diminishes to form the upper portion 0 of smaller diameter than the lower portion 0'. The wick-tube d surrounds the upper portion 0 of the central draft-tube c and is secured to the draft-tube c at the shoulder 0 The wick d fits around the lower portion 0 of the tube 0 and around the wicktube d, and is adapted to be raised or lowered thereon by anysuitable form of mechanism. A collar 6 surrounds the wick d at the upper end thereof and serves as a guide for said wick. The upper inner edge of the wick-tube d is formed with the inwardly and downwardly projecting lip f. This inwardly and downwardly projecting lip fforms a kind of.

beading around the interior of the tube (Z, upon which any drippings from the wick will collect in the form of globules. The lip f permits these globules to fall down between the inner surface of the wick-tube d and the outer surface of the contracted portion 0 of the tube 0. By the employment of this lip f the inner surface of the tube (1 is kept free from oil, and the disagreeable odor arising therefrom is obviated. Below said internallyprojecting lip f in the walls of the wick-tube cl are formed the openings g, arranged in any suitable manner at intervals around said tube. The upper portion 0 of the central draft-tube c is of such a diameter at its upper end that when the wick-tube d is in place there is sufficient space between it and the wick-tube d to allow any drippings escaping over the edge of said wick-tube d to pass down between the said wick-tube d and the upper portion c of the draft-tube o. The lower portion 0' of the tube 0 being of larger diameter, and as the lower end of the wick-tube d is secured to the outer face of the draft-tube c at the shoulder 0 a close connection is made between the tubes, so that any drippings falling down between the wick-tube d and the upper portion 0 of the draft-tube 0 will be prevented from any farther downward progress. The opening g in the walls of the wick-tube d permit of the escape of any such drippings, which will accordingly be again absorbed by the air up through the central tube 0. This the wick d, thus preventing all liability of any of the oil escaping down through the tube 0 to the opening at the bottom thereof and thence to the table supporting the lamp. The openings 9 in the wick-tube d perform several important functions. They permit of the escape of any gas generated in the fount, while they also serve to cool the interior of the lamp as the heat-flow is broken by the perforations.

The flame-spreader 'i is provided with the annular groove or depression j at such a point thereon that when said flame-spreader is in position said groove will come opposite the internally-projecting lip f of the wick-tube d, thus permitting any oil escaping from the wick to pass over the edge of the wick-tube (1, while at the same time it permits the air to pass between the flame-spreader 11 and the wick-tube d.

To obtain a thick steady flame, the flamespreader 'i has seen red therein the perforated truncated cone is, which serves to check the rush of air upwardly in the spreader. This perforated cone is is situated below the top of the wick-tube (1, so that the air is retarded below the point of combustion, and a more even steady flame is obtained,

I do not confine myself to the particular construction shown, as the central draft-tube 0 may have an equal diameter for its entire length and carry the wick d. A tube could be inserted within the central draft-tube to catch the drippings, the internally and downwardly projecting lip being formed on the upper inner edge of the draft-tube.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In alam p, the combination with thefount,

of a wick tube having on its upper and inneredge an internally and downwardly projects ing lip, and a tube within said wick tube adapted to receive any drippings from said lip of the wick tube, said two tubes being secured together so as to form a receiving trough, substantially as set forth.

2. In a lamp, the combination with the fount, of a wick tube having on its upper and inner edge an internally and downwardly projecting lip, and a tube within said wick tube adapted to receive any drippings from said lip of the wick tube, said two tubes being secured together so as to form a receiving trough, and said wick tube having perforations therein above the point of union of the tubes, substantially as set forth.

3. In alamp, the combination with the fount,

of a wick-tube having formed integral therewith on its upper and inner edge an internally and downwardly projecting lip, and a tube within said wick tube adapted to receive any drippings from the wick tube, said tubes being secured together, and said wick tube having perforations in the wallsthereof above the point of union of the tubes, substantially as set forth. 4. In alamp, the combination with the fount, of a wick tube having on its upper edge an internally and downwardly projecting lip, a tube within the wick tube adapted to receive any drippings from the wick tube, and a flame spreader supported on said inner tube, and having the upper part thereof perforated, and having an annular depression in line with the inwardly and downwardly projecting lip of the wick tube so as to give space therefor, substantially as set forth.

In testimony whereof I, the said WILLIAM M. HOERLE, have hereunto set my hand.
