4 Claims.

This invention relates to improvements in wicks, and more particularly to wicks of tubular form adapted to be raised andr lowered by gear-mechanism. 1 f

Heretofore, it has been usual to mount wicks of tubular form in perforated-'metal tubular carrers, the perforations of which carriers intermesh with the usual gear-mechanism employed for raising and lowering the wick for adjusting the same. .This carrier is comparatively expensive to make and requires additional expense for the assembly or mounting of-the wick in the carrier for commercial sale or use.

One object of this invention is to provide a tubular wick with lower-cost means in place of the present type of tubular metal carrier, for engagement with the raising-and-lowering gearmechanism.

Another object of this invention is to provide a tubular wick with low-cost means woven along with the wick when the latter is made, in order to take the place of the more expensive tubular metal carrier, for lcooperative action with the raising-and-lowering gear-mechanism usually employed with the present type of carrier.

Another object of this invention is to provide an improved wick formed of simple elements readily manufactured and readily assembled to produce a durable, efcient construction at minimum cost.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.

' Fig. 410'is`a front elevation of a mod ed form of tubular wick formed of molded 'or felted bers with wire screening Yei'nb'e :l"ded in the outer face of thewick; and f Fig. 11 is a vertical sectional View on line I I-l I of Fig. 10. Y l

Referring to Figs; l tov 5of`the"drawings, the wick 20? illustrates a tubular wick made from a strip ot' wicking shaped into tubular form and having the ends or edges 2l abutted and joined together'in any suitable way, as for example, by sewing with stitches 22 of thread or other suitable material. The wick 2|] has two plys 23 and 24, each y`ply`having longitudinal textile strands 25 interwoven with transverse textilel strands 26, the two plys being connected by binder-strands 21. Raiser-wires 28 of any suitable'metal, as for example,brass 'of suitable stiffness, such for example', as half-hard brass, extend transversely around the wick andare 'interwoven with the longitudinal strands 25, thus providing exposed raiser-wire sections 29 arranged in longitudinal groups at a suitable acute angle to the vertical to be properly engaged withfthe teeth of: lgears 3D and 3l, which gears are rigidly secured yto the shaft 32 rotatably mounted in tube 33, which tube is secured to members 34 and 35 respectively secured to the outer tubular wall 36 oi the annular oilchamber 31. A hand-wheel 38 secured to shaft 32 can be rotated in one direction or the other, to cause the gear-teeth of gears 3|] and 3| engaging the raiser-wire sections 29 to raise or lower the tubular wick, depending on which direction the hand-wheel is rotated.

In the form of the invention illustrated in Figs. 6, 7 and 8, the wick 39 includes a lower portion or section 40, and an upper portion or section 4I. The lower wick-section 49 is formed from a strip of wicking formed'up to tubular form and having its adjacent edge-portions 42 suitably joined together as by stitches 43 of thread or the like. The lower wick-section 4l] is secured to the upper wick-section 4I by having its top-edge portion 44 joined to the bottom-edge portion 45 of the upper wick-section 4I by suitable means, as by stitches 43 of thread or the like. The upper wicksection 4l may be of any suitable type, such as woven or felted construction, either seamless, or seamed or non-seamless, although the particular form illustrated in the drawings is seamless.

The particular lower section 40 illustrated in the drawings is a two-ply fabric having plys 41 and 48, each ply having transverse textile strands 49 extending transversely around each ply of the wick-section 40 and interwoven with longitudinally-extending stiifening-wires 50 extending up and down each ply of the wick-section 4U. The outer or face-ply 41 of the wick-section 40 has transverse raiser-wires I extending transversely around the wick and interwoven with the longitudinal stiffening-wires 50. Binder-strands 52 extend transversely around the Wick-section 4S and serve to connect the two plys together.

In the form of the invention illustrated in Fig. 9, each of the raiser-wires 53 is composed of two wire-strands 54 twisted together.

Referring to Figs. and 11, the tubular wick 55 is made from a strip of molded or felted wicking having a strip of screening 55 embedded in the outer surface thereof. The strip of wicking is shaped or formed or rolled up into tubular form and has its adjoining edge-portions 51 suitably joined together as by stitches 58 of .thread or the like. The screening 56 has raiser-wires 59 extending transversely around the wick, and longitudinal or up-and-down wires 60 are interwoven with the wires 59, the wires 60 being arranged at a suitable acute angle to the vertical to bring the raiser-wire` sections 6| in proper position for meshing with the gear-teeth of the raising-and-lowering gears. In making the wick 55, the screening 56 is laid on top of the screen of a mold or of the paper machine, and a suitable usual type of suspension of bers of sulphite pulp and/or cotton and/or asbestos or the like in water is poured over the screening 56 and over the screen (not shown) of the paper machine or mold, whereby a strip of wicking similar to that illustrated in Fig. 11 is produced, with the wire- 40 screen 56 embedded in one side thereof for a portion of the height' thereof.

Wicks made according to the present invention thus have suitable means such as the raiserwires which cooperate with the raising-and-low- 45 ering gears, and, therefore, it is not necessary to employ the usual type of perforated-metal tubular carriers, which latter are more expensive to make and apply to wicks. Applicants wick may, therefore, be referred to as a carrierless wick.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
