WICK FOR LIQUID FUEL BURNERS Filed Feb. 23, 1937 Mfr/7am 2 .17%,

Patented June 21, 1938' UNlTED STATES PATENT ()FFEE 2 Claims.

The present invention relates to wicks for liquid fuel burners, and has particular reference to Wicks of the character illustrated and described in my copending application Serial Number The invention contemplates a novel construction of wick, which possesses a remarkably high degree of capillary attraction, thus enabling the fuel to more quickly reach the flame edge over definitely prescribed paths, than any other wick of the same general character, thereby providing for a very quick lighting of the. wick, and assuring an even burning of the flame.

In carrying out the invention, I comprehend the use of a single weft strand including spaced pairs of vertical runs interwoven with horizontal warp strands in a manner to provide the wick with comparatively thick spaced runs or paths which materially increases the capillary 2O attraction of the wick, with the resultant ad-- vantages above specified.

The nature and advantages of the invention will be more readily understood from the following detail description when read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a fragmentary elevation of the invention.

Figure 2 is a vertical sectional view on line 22 of Figure 1.

Figure 3 is a horizontal section on line 33 of Figure 1.

Figure 4 is a view similar to Figure 1 of a modified form.

Figure 5 is a sectional view on line 5-5 of Figure 4.

Figure 6 is a horizontal section on line 6--6 of Figure 4.

Figure 7 is a horizontal section on line 'l-l of Figure 4.

Figure 8 is a horizontal section showing Figures 6 and 7 combined.

Referring to Figures 1 to 3 inclusive, I have illustrated a wick composed of a single weft strand including spaced pairs of vertical runs 10, and horizontal warp strands II and [2 respectively. The wick of course may vary in dimensions, both with regards to the size of the respective strands or the depth of the wick without departing from the scope of the invention. In this form of the invention, however, the Warp strands H and H! are alternately interwoven over and under each pair of said runs, thereby maintaining the runs of each pair in contacting engagement throughout their length, or across the entire width of the wick. Manifestly, the respective pairs of contacting runs are equidistantly spaced throughout the wick, and also extend across the. entire width of the wick, forming'part of the flame edge, and also part of the continuous fuel conducting lower edge. Consequently, the respective runs of each pair of said runs unitedly define a comparatively thick run, which materially enhances the capillary attraction of the wick and enables the fuel to more quickly reach the flame edge over such prescribed paths.

In Figures 4 to 8 inclusive I have illustrated a slightly modified form of the invention, wherein the spaced pairs of vertical runs of the weft strands are indicated at IE! and interwoven with the warp strands H and I2 respectively. The warp strands H are interwoven over and under the respective pairs of the vertical runs Ill of the weft strand, while the warp strands I2 are interwoven between the respective runs of each pair of said runs. Obviously, the warp strands II and 12 are alternately interwoven with the vertical runs Ill, the Warp strands l2 spacing the respective runs of each pair of said runs at different points, thus dividing each pair of said runs into sections which are arranged in staggered relation over the area of the wick. This construction, coupled with the fact that the vertical runs Ill extend across the entire width of the wick, forming part of both the flame edge and the continuous lower fuel conducting edge, affords the wick an outstanding relatively high degree of capillary attraction. It has been found in use that both forms of the invention disclosed provide a wick which possesses a longer life than other wicks of similar character, and one which maintains this outstanding high degree of capillary attraction throughout its entire length. By virtue of this fact, the fuel is carried very rapidly from. the lower edge to the flame edge of the wick, thus assuring quick lighting, while the wick renders maximum service with a minimum consumption of fuel.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is herein illustrated or described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

Warp strands interwoven over and under the respective pairs of said vertical runs, additional horizontal warp strands located between the first mentioned warp strands and interwoven between the respective runs of each pair of vertical runs, thereby dividing all of said runs into sections arranged in staggered relation over the area of the wick to materally enhance capillary attraction, said vertical runs extending across the entire width of the wick and forming part of said 10 edges.
