:
In a lamp according to this invention the body is formed by two cases or capsules
and is designed to contain, in addition to a certain quantity of oil, spirit, or essence,
a porous or absorbent substance, such as sponge. It is provided with a central
receptacle for the wick fixed to the upper part of a nipple on one of the cases. The
wick passes through a sheath on a metallic case or capsule formed of a thin-and
moveable piece which fits easily over the nipple. This sheath and case. or capsule
may conveniently be made in one piece. The upper part of the capsule and wick
sheath terminates in an internal rim or lip. The office of this rim or,lip is to
obviate the necessity of frequent regulation of the wick, and to insure sure and
rapid lighting. By reason of this rim, against which the wick constantly bears,
the position of the wick is invariable and it neither carbonises, nor goes out.
Each lamp is hung by a suspender and a globe of any colour is placed on it.

IMPROVEMENTS IN LAMPS PARTICULARLY APPLICABLE TO LAMPS OF THE KIND
USED IN ILLUMINATIONS (a communication to me from abroad by Frédéric Besnard
of Paris in the Republic of France)
This invention has for object to produce a lamp particularly suitable for public
or private illuminations, and which, while being cheap, will be such as to afford a
constant and steady light, and be capable of being rapidly lighted and adjusted.
The accompanying drawing represents in-vertical section a lamp according to this
invention.
The body A is formed by two cases or capsules a a', soldered or otherwise fastened
together, and contains, in addition to a certain quantity of oil, spirit, or essence,
a porous or absorbent substance such as sponge A¹. It is provided with a central
receptacle 6 for the wick M, the receptacle b being retained in the upper part of a
-nipple B, which forms the upper part of the upper case or capsule a. The receptacle b
is a split tube, it is compressed to pass through the opening of B, after which it
expands into contact (with slight friction) with the interior surface of B. The
wick passes through a sheath G on a metallic case or capsule formed of a thin and
movable piece, which fits freely over the nipple B, and rests on the top of the case
or capsule a. The sheath G and its case or capsule may conveniently be made in
one piece as shewn. The upper part of the wick sheath G terminates in an internal
rim or lip E. The office of this rim or lip is to obviate the necessity of frequent
regulation of the wick, and to insure sure and rapid lighting. By reason of this
rim E, against which the wick M constantly bears, the position of the wick 'is
invariable, and it neither carbonises, nor goes out. Each lamp is hung by a
suspender D, and a globe O of any colour is placed on it.
Having described the nature of the said invention and the manner of carrying
the same into practical effect as communicated to me as aforesaid I would have it
understood that what I claim as the invention secured to me by the herein before in
part recited Letters Patent is :-
:
1. In a lamp the use of a wick sheath such as G with enlargement as and for the
purpose described above.
2. In a lamp the use of a wick sheath such as G with a lip such as E at its
upper part as and for the purpose described above.
3. The improved lamp as described and illustrated..

In Witness whereof I the said William Lloyd Wise have hereunto set my
hand and seal this twenty seventh day of March in the year- of our Lord
one thousand eight hundred and eighty three.
