Improvements in Lamp Wicks.
I, HENTIR SARAFLAN, Merchant, of the City of New York Borough of Man-
hattan, in the County and State of New York, United States of America, do
nereby declare the nature of this invention to be as follows:-
My invention relates to lamp wicks, particularly to those adapted for burning
kerosene or petroleum. The object of the invention is to provide a wick which
will produce a bright and steady flame, which will be incombustible and there-
fore will not char, which will not clog or burn low, and which will not require
any trimming or cleaning.
The invention consists, essentially in combining with a lamp wick proper of
any ordinary or approved structure and material, an incombustible top made of
asbestos or equivalent material, and a wire gauze or netting which holds said
top in connection with the wick proper.
The incombustible top consists of asbestos, loosely placed above the top of
the wick proper, and held in position by the gauze or netting which may be
made of iron or other wire, and is connected with the wick proper
suitable
manner, for instance, by wire staples or by stitching.

I prefer to place, in the incombustible top, in contact with the loose asbestos,
an incombustible strip extending transversely of the wick and in contact with
the bend or top of the wire netting, but preferably out of contact with the top
of the wick proper. This incombustible strip is made of comparatively stiff
asbestos millboard, and serves to partly stiffen the upper part of the incombustible
top, and partly to retain such impurities as are generally contained in commercial
kerosene or petroleum. The arrangement of the strip may be varied. It may

be enclosed in the loose asbestos up to the top, so that only its top edge
or exposed, or the loose asbestos may extend only about half-way up the incom-
bustible strip at each side thereof, or it may extend up to the top of the strip,
but only at one side thereof, so that the other side of the strip is in contact with
the wire-netting. While I prefer to use the strip it is not absolutely necessary,
and satisfactory results may be obtained in many cases without it, although the
use of such strip will improve the reliability and luminous power of the wick.
It will be obvious that the top of my improved wick being incombustible,
cuarring and clogging of the wick, and Hickering and unsteadiness of the flame
will be avoided. The loose asbestos insures a good capillary action and a proper
feed of the fuel. The asbestos strip acts as a filter and stiffener. The wire
netting holds une loose asbestos and the asbestos strip in position and makes the
top of the wick very strong and durable.

page_text: I, HENTIR SARAFLAN, Merchant, of the City of New York, Borough of Man-
hattan, in the County and State of New York, United States of America, do
hereby declare the nature of my invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
-
My invention relates to lamp wicks, particularly to those adapted for burning
kerosene or petroleum. The object of the invention is to provide a wick which
will produce a bright and steady flame, which will be incombustible and there-
fore will not char, which will not clog or burn low, and which will not require
any trimming or cleaning.
These objects I attain by the construction shown in the accompanying drawings,
in which
Figure 1 is a side elevation of an improved lamp wick constructed according to
my invention;
Figure 2 is a sectional elevation thereof; and
-
Figures 34 and 5 are sectional elevations of slightly modified forms of the
wick.
My invention consists, essentially in combining with a lamp wick proper of
any ordinary or approved structure and material, an incombustible top made of
asbestos or equivalent material, and a wire gauze or netting which holds said
top in connection with the wick proper.
In the drawings, A indicates the wick proper, B the asbestos top, and C the
wire netting.
The wick proper A, as above stated, may be of any approved construction and
material, for instance, an ordinary cotton wick will do.
The incombustible top B consists of asbestos, loosely placed above the top of the
wick proper A, and held in position by the wire gauze or netting C, which may
be made of iron or other wire, and is connected with the wick proper A in any
suitable manner, for instance, by wire staples or by stitching as shewn at D.
I prefer to place, in the incombustible top B, in contact with the loose asbestos,
an incombustible strip B' extending transversely of the wick and in contact with
the bend or top C¹ of the wire netting, but preferably out of contact with the
top of the wick proper B. This incombustible strip is made of comparatively
stiff asbestos millboard, and serves to partly stiffen the upper part of the incom-
bustible top B, and partly to retain such impurities as are generally_contained
in commercial kerosene or petroleum. The arrangement of the strip B'
varied; as shewn in Figure 2, the strip is enclosed in the loose asbestos up to the
top, so that only the top edge of said strip B is free or exposed. In Figure 3
the loose asbestos extends only about half way up the inconibustible strip B' at
each side thereof. In Figure 4 the loose asbestos extends up to the top of the
strip B, but only at one side thereof, so that the other side of the strip is in
contact with the wire netting C.
may be
Referring to Figure which shews a slight modification, it will be observed
that the lower ends of the vertical wires at opposite sides of the gauze cap C are
bent first inward and upward as at c so as to converge towards one another within
the body of the wick, and then outwards as at c so as to diverge upwardly, said
wires terminating as at within the body of the wick. By this means a firmer
connection is ensured between the incombustible top B and the wick proper A.
While I prefer to use the strip B¹ as described, this part is not absolutely

use of said strip B¹ although the use of such strip will improve the reliability and
luminous power of the wick.
it will be obvious that the top of my improved wick being incombustible,
charring and clogging of the wick, and Hickering and unsteadiness of the flame
will be avoided. The loose asbestos insures a good capillary action and a proper
feed of the fuel. The asbestos strip acts as a filter and stiffener. The wire
netting holds the loose asbestos and the asbestos strip in position and makes the
top of the wick very strong and durable. It will be obvious that no trimming
will be required for a wick constructed according to my invention.
While I have shewn the application of my invention to flat wicks, it will be
evident that it may be applied with equal advantages to round or tubular wicks.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved wick consisting of the wick proper (A) the top (B) consisting
of incombustible material, and the wire netting (C) secured to the wick proper
and enclosing said incombustible material.
2. The improved wick consisting of the wick proper (A), the top (1) consisting
of loose incombustible material in contact with the top of the wick proper, and the
wire netting (C) secured to the wick proper and enclosing said loose incombustible
material.
3. The improved wick consisting of the wick proper (A), the top (B) consisting
of loose incombustible material in contact with the top of the wick proper, the
wire netting (C) embracing the top of the wick proper and secured thereto, said
netting being bent and enclosing the said loose incombustible material, and the
comparatively stiff strip (13) of incombustible material located at the bend of the
netting (C) and in contact with the loose incombustible material.
4. The modified construction of incombustible wick having the lower ends
of the vertical wires of the netting bent and secured to the wick proper substan-
tially as shewn in and described with reference to Figure 5.
