WICK MATERIAL.

SPECIFICATION forming part of Letters Patent No. 431,033, dated July 1,1890. Application led January 24, 1889. Serial No. 297,431. (No model.)

To all whom, it may concern:

Be it known that I, MYRON II. CHAPIN, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Vick Material, of which the following is a full, clear, and exact description.

This invention has for its object the production of a material made from raw fibrous matter suitable for lamp-wicks and other useful purposes, which shall be less expensive than the ordinary woven cotton wick, .more lasting, and possess a more perfect capillary action, thereby conducting the oil or burning-fluid more evenly to the flame.

The invention consists in a prepared wick material composed of raw fibrous matter in layers or slivers and adhesive substance, substantially as hereinafter described and pointed out in the claims.

The ordinary cotton wicks now in general use are manufactured from cotton yarn by the process of weaving and are consequently more expensive and objectionable for operation by the usual ratchetwheel used to raise and lower the wick, owing to loosening of the exterior bers by the operation of the ratchet-wheel, the tendency of said fibers being to cling to and wind upon t-he teeth and shaft of the ratchet-wheel. My improved wick material is free from these objections,

y as its exterior surface is comparatively hard and firm, while its interior elasticity is such that its exterior surface or surfaces are at all times held with a gentle pressure against the teeth of the ratchet-wheel, and the wick is thus raised and lowered evenly and with certainty.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 represents a View in perspective of a lampavick made of my improved material, and Fig. 2 a transverse section of the same upon a larger scale.

Preferably I shall use raw fibrous cotton and take any suitable quantity of raw cotton and immerse it in a solution of caustic soda, which may be in the proportion of onehalf of an ounce of the soda to three galmain in the alkaline solution until the mass,

is thoroughly saturated, which will have the effect of removing oleaginous matter from the cotton and of preparing it for aftertreatment. The cotton is then removed from the alkaline bath and the surplus liquid removed by pressure or other suitable means. The cotton is then carded by the ordinary wellknown mechanism into slivers or sheets, of which a suitable number are placed one upon the other to form a combined sheet having a thickness depending upon the thickness of the wick or wick material required to be produced. The sheet of carded cotton thus produced is then passed through or immersed in a thin solution or preparation ot some suitable adhesive material, )referably of starch and water made hot. The cotton is allowed to remain in the same starch or other adhesive material until said cotton is completely saturated with the starch or adhesive material, which serves to bind together and stiffen the fibers. The surplus starch or adhesive material is then, by rollers or other suitable means,

pressed out of the sheet. The two exterior surfaces of the sheet are then coated with a thickv solution of the starch or other suitable adhesive material, and then passed between pressure-rolls, by which the adhesive coating is pressed into the surfaces of the sheet, impregnating the same and producing in or upon said surfaces a iirm protective skin of compressed cotton fiber and compressed impregnating adhesive material which is tough and even, while the interior bers are, by this rolling pressure, somewhat loosened and rendered pliable and porous or open. When the sheet thus made is dried, it is ready for use and may be cut into wicks of the required length and width.

In the drawings, A indicates a wick made from the prepared cotton material, as described, a a indicating theY inner cotton slivers, of which there may be any desired number, and l) b indicate the outer compressed skin of the Wick. ,The wick material produced from cotton prepared substantially as described will pre- IOO sent a thick massof cotton in a fibrous elastic form in its interior, and having` a comparatively inelastic surface or protective skin on its exterior, thus admirably providing alike both for a good capillary action of the wick and a tough gripping-surface on its exterior for the ratchet-wheel or means used to raise and lower the wick when applied to the lamp. It will be understood that any of the ordinary cotton mechanisms may be used in preparing my improved Wick material, such as the ordinary vats, carding-machines, starching or sizing machines, pressure-rollers, and drying chambers or devices. As all of these devices are Well known a special description of them is not here necessary.

Having thus described my invention,\vhat I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a wick material made of raw fibrous material having its interior stiffened and held with adhesive substance and its exterior surfaces formed with a protective skin of compressed fibers and adhesive substance, as herein shown and described.

2. A Wick material composed upon its interior of stiffened iibrous material in a raw state having the oleaginous matter essentially removed therefrom and with the exterior sur- MYRON H. CHAPIN.
