LAMP-WICK.

To all whom z'ltmag/ concern:

Be it known that I, WrLLIAM R. ARNOLD,

a citizen of the United States, and a resident of Geneva, `in the county ofFillmore and State of Nebraska, have invented cer-l t-ain new and useful Improvements in Lamp Wicks, of which the following is a specifi.- cation, reference being had tothe accompanying drawings. This invention has relation to certain ne and useful improvements in flatv textile wicks employed in connection with illuminating lamps and oil stoves, consuming kerosene or similar hydrocarbon oils; and the object of my invention is toprovide a wick of this general character of a simple and inexpensive nature and of durable construction so arranged that the wicks will not be consumed and .will give an exceedingly large and brilliant flame, absolutelyfreeof smoke and objectionable odors in that .the wick is provided with an indestructible reinforcement placed upon opposite sides, insuring complete combustion of the oil without in any way charring or carbonizing the wick.`

With these and other objects in view the present invention consists -in the combination and varrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood thatT changes in the specific structure shown and describedmay be made within the scope of the claim, without departing from the spirit of the invention. v Y Inthe accompanying drawings forming a part of this speciicatiomand in which like numeralsof reference indicate similar parts in the several views: Figure 1, shows an elevational View of a wick constructed accordingto my invention. Fig. 2, is a section on line 2, 2, of Fig. l. Fig. 3, shows a detail of one of the securing wires, and Fig. 4,

asbestos, kwhich tips the ends but leaves the edges of the wick exposed.

Inthe drawings the numeral l, indicates a flat textile wick the ends of which are tipped with a non-burning reinforcement hood 2, made of sheet asbestos or so called asbestos board. rIhe reinforcement is in the 1 form of two similar square members 2,-2 of a width equal to the width of the wick insuring t-he top and the edges 3, of the wick being exposed, as shown. Each reinforcement as disclosed covers one side of the burning end of the wick. In order to hold these reinforcements in proper position, I employ one or more wire members 5, preferably made of copper, which are forced through the wick adjacent to the ends of the reinforcements, as shown in Fig. l, and are then under pressure, forced into the reinforcements as shown in Fig. 2, so that the Wires will not project beyond the sides or faces of the wick, insuring the wick working freely within the wick tube of the burner. The ends of these preferably copper wire members 5, are then clenched to securely hold the reinforcements to the end of the wick. In securing the reinforcements the wick end is compressed, so that the thickness of the ,wick at the reinforced end is no greater than the thickness of the body of the wick as will be understood in referring to Fig. 2. This is necessary in order to in sure the free movement of the reinforced wick end within the wick tube of the burner. A wick provided with one of these incombustible hoods, can be readily introduced into the wick tube, and can be easily raised and lowered. In touching a flame tothe wick, the generated gases will at once ignite Vinsuring a large, brilliant, smokeless flame. Owing to the impurities within the oil, the reinforcements 2, which never becomes charred or burnt, will, however, finally become clogged with impurities, so that the gas generation will not be so free and perfect as where the capillary qualities of the asbestos reinforcement are perfect. When this occurs, the operator simply reverses the wick and uses the opposite end. An admirable feature of these wicks resides in the fact that they can be turned down very low, as when used in a night lamp or in sick rooms, without giving off any ob jectionable odors. My wicks are further especially adapted to be used in connection with lanterns, burning with a bright, smoke` less flame. It is of course understood that vall sizes of flat Wicks can be provided with these hoods, which are inexpensive, durable and efficient and can be easily attached tod a Wick.

vHaving thus described my said invention,`

what I claim as new and desire tosecure by United States Letters Patent is:
