SPECIFICATION forming part of Letters Patent No. 595,884, dated December 21, 1897.
Application filed April 3, 1897. Serial No. 630,584. (No specimens.)
To a whom it may concern.-
Be it known that I, OHARLEs L. MARSHALL,
' a' citizen of the United States, residing at Ce- .dar Grove, in the county of Essex and State of New Jersey, have invented a new and use-.
ful Improvement in Lamp-\Vicks, of which the following is a specification.
The object of my invention is to strengthen lamp-wicks which have been subjected to processes which weaken their texture though improving their lighting powers.
My invention is particularly valuable in dealing with carbonized wicks, a process for producing which is the subject of a patentconcurrently pending herewith. I attain this object by using in the texture of the wick some material which when subjected to the process in question will not be so affected by that process that it loses its textile strength; or I may attain my object by combining with the lamp-wick material so treated new material which has not been affected by any such treatment. In other words, I aim to produce, as an article of manufacture, a lamp-wick containing some strong material on which the ratchet may act, though the greater part of the wick may have been weakened by a process which is intended to improve its capillary attraction or its lighting capacity.
In the process of carbonizationwhich is the subject of the patent before referred to the fiber of the wick is necessarily weakened to some slight extent from being subjected to temperatures ranging from 500 Fahrenheit to 1,200 or more. To supplement the strength of the wick in order to withstand the action of the ratchet, I introduce fibers of a substance which will not be weakened by the carbonizing process. Asbestos is the substance best adapted to this purpose.
In the drawing a portion of a wick is shown, A being one of the heavy strands of the warp, and B a strand of the weft. About each strand of the weft is twisted asbestos fiber C. This maybe woven into the strand or twisted about it, as shown. The amount of asbestos used may be as much as sixty-five per cent. without destroying the capillarity of the wick, but a much smaller amount is sufficient. Even ten per cent. will give good results.
- As above noted, the material of which the wick is made may be carbonized first and the asbestos woven in with it afterward. Thus it willbe seen that there are many ways of applying my idea in practice. For example, I may use a tinsel cord in the place of the asbestos. V
What I do now claim, and desire to secure by Letters Patent, is-
1. As an article of manufacture, a lampwick composed of two sets of fibers, one set weakened by distillation and. carbonization, and the other set not susceptible to such weakening. p
2. As an article of manufacture, a lamp wick having one set of fibers weakened by the abstraction of oleaginous and gummy matters and another set of fibers interwoven with said weakened fibers to strengthen them.
3. As an article of manufacture, a lampwick composed of interwoven carbonized and asbestos fibers. 4. As an article of manufacture, a lampwick having a warp and weft of carbonized fibers and asbestos fibers twisted about the strands of said weft.
5. As an article of manufacture, a lampwick composedv of a warp and weft of carbonized fibers, and asbestos fibers twisted about the strands of said warp and weft.
6. The method of manufacturing lampwicks which consists in subjecting a wick composed of two sets of fibers, one of a refractory material and the other of a non-refractory material, to a weakening ameliorative process which acts on one of said sets of fibers and does not affect the other.
7. The method of manufacturing lampwicks which consists in subjecting a-wick composed of two sets of fibers, one of a refractory material and the other of a non-refractory material, to a heating process which acts on one of said sets of fibers and does not affect the'other. 4
8. The method of manufacturing lampwicks which consists in subjecting a wick composed of two sets .of fibers, one of a refractory material and the other of a non-refractory material, to a carbonization process which acts on one of said sets of fibers and does not affect the other.
