FREDERICK W. SPANGLER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MANTLE LAMP COMPANY OF AMERICA, OF CHICAGO, ILLINOIS, A CORPORATION.

WOVEN WICK.

Application filed .Tune 30, 1924. Serial No. 723,295.

The invention relates to the construction of wicks which are, preferably of the woven variety, and it concerns the arrangements of the constituent elements thereof.

The novelty disclosed is the variation in the spacing of the weft cords, which hold the warp cords and constitute the wick. At the upper extremity or burning end of the wick, the wett cords are spaced relatively close together, to produce a compact wick which will notray out during its use, while at the lower and bifurcated end or' the wick,

which is immersed in oil, the weft spacing is approximately twice as great as at the upper end, making the lower end of the wick materially looser in weave. This construction facilitates and cheapens the manufacture and cost of making wicks due to the increased production and decrease in amount of wett cords used.

Furthermore, a wick woven according to this design has an increased oil-capillarity due to the looseness of the weave `throughout the major portion of its length. This design makes it possible to give the upper end of the wick a stii weave, so that the burning end will hold its shapey properly, and at the same time the lower end, which is immersed in the oil, is woven looser in order to increase the capillarity.

The invention will be understood if reference be made to the accompanying drawing, in which- Figure l is a view showing the wick in elevation, and

Figure 2 is a sectional view taken on th line 2 2, Figurey l.

l is the entire wick, while 2 and 3 are, respectively, the upper portion and the lower loosely-woven portion.l The warp threads 4 and the weft threads 5 are made of cotton or any suitable substance, and the weft threads below the point marked 6, or other point of predetermined altitude, are spaced sufficiently to produce the desired looseness, 5 the Quantity of oil which may be drawn by capillary action to the flame in a given time, being somewhatr dependent upon the openness of the submerged part of the wick. It has been lound that satisfactory results may be attained if the lower weft threads are arranged twice as far apart as the upper weft threads.

The wick is tubular and may be made on Y a loom which is capableof producing a tubular wick, the variation of wett cord spacing being attained by varying the take-up mechanism of the loom in a manner well known to workers in the textile art.

A wick made as herein described, will not 00 fray out at its upper end which will be relatively stiii", even though the submerged portion is so loose as to be incapable of retaining a definite tubular form. Also, there is the advantage of cheap production due to 05 the lessening of the quantity of yarn required to produce a. wick, as well as to a decrease in the timev absorbedvin weaving. The wick is cleft at the lower end, so that it may straddle the vane which unites the concentric tubes of a central-draft burner.

Having thus described my invention, what I claim is:

A cylindrical woven wick including uniformly spaced warp threads, and weft threads, said wett threads in the lower part of the wick being more widely spaced than the weft threads in the upper part of the wick.

In testimony whereof I aliix my signature.

FREDERICK w. sPANGLER.
