(01. 139-388) 4 Claims. This invention relates to an improvement in wicks and more particularly to woven wicks for oil stoves, etc. Woven wicks as heretofore pro duced have been generally characterized by two 5 opposite face plys tied together by the usual lon gitudinal binder-strands extending between the said plys and have possessed many objections among which may be mentioned relatively low strands which inthe present instance comprise six strands, each respectivelydesignated [2, I3, l4,’ I5, l6 and I1. The said'warp strands pass through the fabric on a long gentle slope and alternately pass over weft strands or picks IS m in one face of the fabric and overlweft strands or picks IS in the opposite face of thefabric; ' By way of example the warp'strand "I2 may be considered and itv will be'gnoted» by reference 10 possession of longitudinal rib-like bulges at di- ’ to Fig. 3 that after passing vover the first, of 10 ametrically-opposite points thereon, unevenness the upper weft picks l8a'the said'strand-misses in their edges, etc., .etc. The present invention engagement with a‘total of'six ‘weft picks l8 andv 19 before appearing onthe-opposite' face contemplates a woven wick of such character as of the fabric for extension around the weft pick will obviate many of the defects above men Illa. The warp strand l2 then extends'diago'n'al Is 15 tioned. ‘ One of the objects of the present invention is ly throughthe fabric on'a long-gentle. slope to to provide a woven wick which will maintain a the opposite'face of the fabric and again misses burning-edge of superior uniformity when in six Weft picks before looping over the‘weft pick use.

Y ’ Another object of the present invention is to 30 common in prior types of tubular woven wicks. With the above and other objects in view, as will appear to those skilled in the art from the By' way of example, the next strand ,back' of present disclosure, this invention includes all strand features in the said disclosure which are novel ' over the prior art. 35 In the accompanying drawing: Fig. l is a View in side elevation of a seamless tubular woven wick embodying the present in vention and shown as mounted in a perforated carrier; m Fig. 2 is a perspective view of the wick prior to its introduction into a carrier; Fig. 3 is a schematic view in longitudinal sec tion illustrating one weave suitable for carrying out the present invention; and .15 Fig. 4 is a similar view of still another weave suitable for use in wicks of the present inven tion. The particular woven wick l0 herein chosen for the illustration of one embodiment of the 50 present invention is of seamless tubular form as shown in Fig. 2 and may be inserted into a tubular perforated metal carrier II in accord ance with usual practice. the warp strand .l'l would be a strand corre sponding inposition and inclination to the warp l2. ‘ ' " The weave illustrated in Fig. 3 may be aptly ' characterized as an interwoven twill inasmuch as each of the warp strands extends through the fabric from one side to the other thereof and does not require the use of binder-strands to tie the two sets of weft strands l18‘andvl-9‘ together. ‘ The particular weave illustrated in Fig.4 in-, cludes a plurality of sets or groups of warp strands which comprise six strands each respectively des ignated 20, 2|‘, 2:2, 231, 24 and 25‘ arrangedjv from the foreground to the background 'in the‘3order‘ Y named. In the‘ upper face of the fabric'~ (as viewed in the drawing) is a series of weft strands or picks 26 and in the opposite face is a cor? responding series of weft‘ strands or picks 21.. The said weft strands or picks 26 in one face are tied to the weft strands or picks 21 in the other face solely by the warp strands 20 to 25 inclusive before referred to. The said' warp strands all extend on a long gentle slope from. one face‘ of the fabric to the other, and like the ‘ The particular weave illustrated in Fig. 3 in- ' weave shown in Fig. 3 each of the said warp 55 cludes a plurality of sets or groups of warp strandsv misses six weft picks between its appear 2 2,134,424 ance upon the respective opposite faces of the fabric. . It may be explained in this connection that in the weave ‘of Fig. 4 the next strand in the background beyond the strand 25 would be an~ other strand corresponding in position to the weft picks located adjacent one surface of the wickj another set of weft picks located adjacent the'other surface of the wick; and’ a plurality of warp strands, all of which warp strands ex, tend diagonally back and forth through the fab— ric, and each of which warp strands alternately position of the strand I 0 and: constituting the. passes over a weft pick of one set of weft picks ?rst strand of another group of similar warp and then over another pick of the other set of strands. weft picks, and passes between a plurality of the ' Both of the weaves illustrated and above de _ intervening weft picks of both sets of weft picks scribed are characterized by high capacity for ' between its leaving and returning to a given set conducting oil to the burning-edge of the wick, of weft picks. which in' each of the ?gures of the drawing is 2.
