No. Patented May 10 1845.
Specification forming part of Letters Patent No. dated May 10 1845; Antedated April 3.
1845; Reissued August 16 1845 No. .
To all whom it may concern:
Be it known that I SAMu-Ei Rusr of the city of New York county and State of New York have invented a new and useful Improvement in Lamp-Wicks to be used in Lamps for Lighting Houses Stores and Other Places and that the following is full and exact description as invented or im-
proved by me.
10 This wick is peculiarly adapted for lamps winch raise or depress the wick by a roller. It consists of a narrow strip of tape about s of an inch wide or a narrow strip of muslin canton flannel or other suitable substance
15 about of an inch wide more or less with the edges of the muslin or canton flannel turned and doubled over so as to meet or nearly so in the center as A Fig. 1 which leaves the edges double and prevents it from
20 raveling which I do with great facility by machinery. This muslin or canton flannel when doubled; farms a strip of course only half as wide viz of an inch wide the same width as the tapes which does not require
25 for the edges to be doubled over. On to each edge of this strip the common candle wick is sewed or otherwise attached as B Fig. 1.
This wick is beautifully adapted for my spring lamp with a thumb piece formerly
30 patented by me which has a flat tube as C Fig. 2 and C Fig. 3 and a narrow wheel or roller in the center of the side of the tube as D Fig. 2 and D Fig. 3 about 4 of an inch wide and a narrow spring about the same
35 width as the roller soldered on to the tube on the opposite side to the roller as E Fig. 2 and E Fig. 3 which spring and roller both act on the strip of muslin or canton flannel in the center of the wick-the spring on the
40 one side and the roller on the otherwithout
touching the candle wick on either edge.
The muslin or canton flannel being tight wove cannot catch or hook in the teeth of the roller as the loose woven wick is subject
45 to do while the sides of the wick being the candle wick connected by the narrow strip of muslin in the center burns up boldly and beautifully at the sides making the most clear and splendid light as the candle wick
50 is kept up by the sides of the strip of muslin or canton flannel without any pressure from the tube allowing a full and free circulation of oil obviating the great evil in the lamp's going out when suddenly moved around
55 which the woven flat wick has always beensubject to. It also burns much better when the oil is burnt down low in the lamp than the woven flat wick and can be afforded for nearly one half the price. This wick when used in the flat tube as above described 60 will flatten andform itself into a perfect flat wick connecting the whole blaze in one clear and splendid sheet while it is also Calculated for the two round tubes connected together by a narrow space in the center as 65 F Fig. 4 which tube I am now about to patent in another separate patent and which will be more fully set forth.
While this wick made the same size and
in the same way will spread out and fit the 70 wide flat tube as described it will also close up by its yielding nature and fit these two narrow round tubes so that I use the same wick both as a close round wick and also as
a wide flat wick. This wick I also make the 75 same and is the same thing without doubling over the edges of the muslin or the canton flannel by leaving the muslin or the canton flannel its full width as described or the width of the inside of the flat tube and 80 sew a quarter of the candle wick on both sides of each edge so as to leave the muslin or canton flannel in the center of the candle wick on each edge which is dividing the candle wick into four equal parts. 85
G Fig. 5 is the edge view of the muslin or canton flannel.
H Fig. 5 is also the edge view of the candle wick sewed on each side of the mus lin or canton flannel. Or the candle wick 90 may be sewed half on one side of one edge of the strip of muslin or canton flannel and half on the same side of the other edge leaving a place in the center between the two candle wicks for the roller to work as I 95 Fig. G.
This wick does not require stiffening on the end to put in the lamp as the woven flat wick as it can be cut off and wet with
the mouth which will mat or condense it to- 100 gether and by pulling back the spring by means of the thumbpiece it is easily inserted and carried down by the roller. The thumb-piece can also be pressed upon with
the thumb to help the spring press harder 105 and carry the wick up and down with more force if required.
Drawings of both tubes as described I herewith send.
When the lamp is burning the twine will 110
immediately burn off (being a nonconductor of the oil) but the candle wick will remain and perform its full office.
What I claim and desire to secure by Let-5 ters Patent is
The lamp wick made or combined as above
described viz. with a strip of tape muslin
canton flannel a piece of twine or any other;
substance and the candle wick attached or
10 combined to the sides as above set forth or in
[FIRST PRINTED 191.3.]
any other way that is essentially the same and for which I request Letters Patent.
Witness my hand this third day of April of April A. D. eighteen hundred and forty-five.
