To all whom, it may concern:

Be it known that I, STEPHENB. MORSS, a citizen of the United States, residing in Rahway, Union county, New Jersey, have invented certa-in new and useful Improvements in Lamp Vicks, of which the following is a specifica-tion.

The object of my invention is to provide a practically non-combustible wick which shall 1o possess all the advantageous oil-feeding qualities of the ordinary cotton wick without the disadvantages inherent in the latter wick, such as its charring, smoking, and production of odors.

In carrying out my invention I provide a noncombustible body or carrier provided on top with a flange or lip, and in contact with said body I place a cotton or other suitablyconstructed brous wick, the upper end of 2o which rests beneath said flange or lip and in contact therewith. Said ange or lip is made porous or perforated to permit the passage through it of oil by capillary action, the oil being fed to said flange by said fibrous or cot- 2 5 ton wick. The flame burns on the upper edge of said flange or lip, and consequently does not reach the fibrous or cotton wick, the result being a pure white light without combustion of the wick material.

The invention further consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure l is a perspective view of the noncoinbustible body forming part of my improved wick. Fig. 2 is a vertical section thereof. Fig. 3 is a corresponding view showing the fibrous oil-feeder in position on the non-combustible body. Fig. 4 is a perspective view of the body or carrier having a perforated iange or lip. Fig. 5 is a central section of a wick having double walls, forming a space to receive wicking material. Fig. 6 is a perspective view of a flat wick having two walls and a fiat top, Fig. 7 is an end view of a rectangular wick-body having a central space, and Fig. S is a perspective View showing a flat wick-bod y hai/'ing a iian ge and a porous wicking attached thereto.

In the accompanying drawings, in which similar letters of reference indicate corresponding parts in the several views, the let- 5 5 ter A indicates a non-combustible wick body or carrier having a fiange or lip a at its upper end, and B is a fibrous wicking material placed contiguous to said body A and resting against the under surface of the flange or 6o lip a.

The bodyA is preferably made of suitable clay and is also preferably made porous in the course of manufacture in any well-known or desired manner of making porous noncombustible bodies, or it may be a longitudinally-perforated body made in a well-known manner. The flange or lip a is also made porous or perforated, so as to serve to convey oil by capillary action to its upper surface from 7o the fibrous wicking B.

The wicking B may consist of the ordinary cotton wicking of commerce, or it may be of any other desired or suitable material which will serve to convey oil to the flange a.

I have shown the body Aand flange a in a single piece of material, which is the preferred construction.

I have shown the body A in tubular form, which will serve with the well-known central- 8o draft lamps or burners, being made of suitable size to pass over the central tube of the lamp. The fibrous wick B is also shown of tubular form fitted over the body A and lying in close contact therewith; but whether my wick is made in tubular form or otherwise is not material to my invention so long as it embraces the characteristics of a body having a porous orperforated fiange or lip and a iibrous wick in contact with said body and resting 9o against the under side of said flange.

By preference the body A extends down about to the bottom of the fibrous wicking B, so that both parts of the complete wick will be equally supplied with oil. 9 5

Then the bodyA is made of porous material, as baked clay, it assists in conveying oil to the flange or lip a, and the crevice between the body A and wicking B also serves to carry up the oil by capillary action in addition to roo the inherent capillary capacity of the fibrous wicking B.

In Fig. 5 the wick-body has double walls, forming a space The wicking B when placed in said space carries the oil to the flange or bridgea, while the double walls serve to thoroughly protect the wicking B.

In Figs. 6, 7, and 8 I have shown the body or carrier A as flat or rectangular, Fig. 6 showing two fiat walls A A joined to the flange or bridge d, the sides or edges being open to permit the insertion of the wicking B between said walls. In Fig, 7 the body A is rectangular, and all four sides forming a central space l) for the wicking B. In Fig. S a single flat plate A is shown having the flange a, and the wicking B may be secured thereto by any suitable means.

W'hen my improved wick is in use the top of the wicking B preferably extends slightly below *the top of the outer metal tube of the lamp-burner, so that the flame will be prevented from reaching said wicking; but the flange cl. projects above said metal tube and presents a proper surface for the flame which burns above the flange a. As the flange a does not consume, it will at all times be level on the top surface to produce an even flame, and there is therefore no necessity of trimming the wick. Much trouble and annoyance is therefore avoided.

My improved wick is practically indestructible under ordinary conditions of use, as the flange a is unaffected by the heat from the flame. The flame burns uniformly and evenly, and as there is no burning of the wick smoking and the creating of odors are prevented and a perfect combustion of the oil takes place and the qualities of the light are improved, because the body A and flange a become heated and volatilize a portion of the oil or convert it into gas before it reaches the flame.

My improved wick is simple in construction, cheap to manufacture, and can be made to fit almost any make of burner, suitable provision being made to enable the wick to be raised and lowered, which can be done in the burner the same as with an ordinary cotton wick.

I do not limit my invention to the details of construction shown and described, as they may be varied without departing from the spirit of my invention.

Having now described my invention, what I claim isl. A wick of inflexible or selfsupporting incombustible porous material, as clay, comprising a Wall serving as a support for a fibrous flexible wick, and an integral flange serving as a continuation of the fibrous ilexible wick, substantially-as described.

2. A wick of inflexible or self-supporting incombustible porous material, as clay, comprising two parallel walls for inclosing and supporting a fibrous flexible wick, and an integral flange upon said walls serving as a continuation of the fibrous flexible wick, substantially as described.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.

STEPHEN B. MORSS.
