page_text: Improvements relating to Lamps and Wicks therefor.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:―
This invention relates to Improvements in lamps and wicks therefor.
One of the said improvements consists in the combination with a perforated
body provided at the base with openings for the passage of a wick, of a wick tube
composed of an inner and an outer shell, the inner shell forming a central draught
Blue and having openings through its lower portion and the outer being supported
above the base of the perforated body so that a space will be left between it and
said body through which air may circulate so as to keep the parts cool.
Preferably the outer shell of the wick tube will be supported by spurs or legs
extend ng from it to the body of the burner. The inner shell may advantageously
be supported by being connected to the outer shell.
Another improvement consists in a wick comprising a cylindric upper portion
and two isolated strips or portions depending therefrom all being woven together
in one piece.
Another improvement consists in the combination with an annular wick tube of
an upwardly tapering shell fitted into the inner shell of the wick tube, extending
above the same, perforated throughout its extent and having mounted upon it a
button or spreader for spreading or deflecting currents of air issuing from the said
upwardly tapering shell.
In the accompanying drawings Figure 1, is a perspective view of a burner
embodying the improvements a part of the body being broken away so as to
exhibit the construction of the wick tube and the combination thereof with the
body. Figure 2 is a perspective view of the wick detached from the burner.
Figure 3 is a perspective view of the wick and a wick carrier. Figure 4 is a
central vertical section of the lamp burner. Figure 5, is a horizontal section of
the burner taken at the plane of the dotted line xx Figure 4. Figure 6, is a top
view of a tapering perforated shell which is fitted into the upper part of the
annular wick tube of the burner and extends slightly above the same. Similar
letters of reference designate corresponding parts in all the figures.
A A¹ designate the wick tube. It consists of two cylindric shells A A¹ made of
sheet metal tubing and arranged concentrically one within the other.
B designates the body of the burner. It is shown as substantially cup shaped
and provided with perforations b in its upper portion. It is in effect an air
distributer. Its lower portion 61 is cylindrical and externally screw threaded to
engage with an internally screw threaded collar in an oil reservoir or fount. The
bottom 6 has two are shaped openings b³ 64.
The outer shell A¹ of the wick tube A A¹ is elevated considerably above the
bottom of the body B and is considerably smaller in diameter than the portion of
the body B that surrounds it, hence a space is formed between it and the body.

page_text: Consequently air entering the perforations b in the upper part of the body B may
descend through the body and pass freely between it and the outer shell of the
wick tube. Preferably the inner shell of the wick tube will also be slightly
elevated above the bottom 62 of the body B although it may be extended down to
the bottom 6* and secured thereto if desirable. This inner shell of the wick tube
has formed in its lower end notches or openings a the upper ends of which are
coincident with the lower end of the outer wick tube shell A¹. Opposite the
upper ends of these openings a the space between the two shells of the wick tube
is closed. As here shown such space is so closed by projections from a ring C.
This ring is seen red all around to the bottom of the outer shell of the wick tube
by being rivited thereto or in any other suitable manner. It is not diametrically
so large as the portion of the body B that is opposite the lower end of the shell A¹
of the wick tube. Consequently it does not preclude the passage of air between
said shell and body. It is provided with a number of spurs or legs a¹ that extend
outwardly and are secured to the body B by means of a solder or otherwise. The
outer shell of the wick tube is therefore supported from the body B by means of
outwardly extending spurs or legs. The inner shell of the wick tube may be
supported by the same means when it does not extend to the bottom 6 of the
body B providing the portions of the ring C that extend inwardly to it opposite
its openings a are secured to it.
The inner shell of the wick tube also forms a central draft flue. Air entering
the perforations 6 of the body descends below the outer shell of the wick tube and
passing through the notches or openings a in the inner shell of the wick tube rises
through the space encircled by the latter. It is found advantageous to arrange
the lowest row of perforations 6 of the body somewhat higher than the bottom of
the outer shell of the wick tube and top of the openings a in the inner shell
thereof, for as the air will have then to descend before it can enter the central
draft flue the flow of air through the central draft flue will be more uniform and
steady and less affected by outside draft.
P designates a plate which is inserted in the central draft flue between the
notches or holes a of the inner shell of the wick tube which forms said flue in
order to prevent air from flowing directly across from one opening a to the other.
In the upper part of the central draft flue an upwardly tapering shell S is fitted.
It is made of sheet metal and at the lower end fits snugly against the interior of
the inner shell A of the wick tube. It is supported by a rod S¹ which is secured
at the lower end in the bottom b of the body B and sustained by the plate P.
The shell S is provided with a socket S³ which fits upon the upper end of the rod S¹
so as to sustain the shell in the position which it is desired to occupy. The shell S
tapers upwardly to such an extent that its upper end which is, a short distance
above the tip of the wick tube, considerably smaller diametrically than the inner
shell of the wick tube. This shell S is perforated throughout its extent preferably
not excepting its top. It has mounted upon it a button or spreader H shown.as
made of sheet metal and flaring outwardly from the base to the upper edge. At
the base this button or spreader is considerably smaller diametrically than the top
of the shell S hence air may escape from a row of perforations in the top of the
shell S around the base portion of the button or spreader. An advantageous way
of securing the shell S and button or spreader together consists in forming a
shank upon the socket S' extending this shank through the top of the shell S into
the base portion of the button or spreader and then riviting the shank over the
base portion of said button or spreader. Outside the wick tube is a conoidal
deflector I made of sheet metal resting on the upper edge of the shell B. The
outer portion of this deflector is extended to form a chimney gallery G spring
fingers i being arranged upon the latter to keep the chimney in place.
A number of perforated sheet metal plates J are arranged between the wick tube
and the body B. Their inner edges are bent upwardly to form rims which snugly
fit around the outer shell of the wick tube and serve to carry off heat therefrom
to the air which passes through these plates.

page_text: The wick C which I use in the wick tube has a cylindric upper portion c and
two isolated portions or strips c¹ c² extending downwardly therefrom. It is woven
in one continuous piece, its strip like portion having selvages or finished side edges.
It is fastened to a sheet metal carrier D of similar shape by means of prongs or by
stitching. The carrier has rows of perforations with which the teeth of a ratchet
wheel E may engage. This wheel is mounted on a shaft E¹ journalled in the body
B and extending through a slot in the outer shell of the wick tube. The outer
end of the shaft is provided with a hand piece by which the wheel may be rotated
to elevate and lower the wick carrier and wick.
The strip like portions c¹ c' of the wick extend into proximity with a wick W
that is fastened by a loop 65 to the bottom 6 of the burner body B and extends
down into the oil reservoir or fount with which the burner is used. This wick W
will carry up oil to the wick C.
The manner in which air will pass into the central draft flue formed by the
inner shell of the wick tube has already been described. It will escape from the
taper shell S in numerous jets. Owing to the fact that it will escape less freely
from the upper part of the shell S than from the lower because of the upward
decrease in size of the shell, some of the air will be forced to escape from the lower
perforations. Because the upward taper of the shell S, the jets of air will be
directed upwardly as well as outwardly. I have found this desirable as the air is
better supplied to the parts of the flame where it is needed than it otherwise would
be. The button or spreader directs outwardly all the air which reaches its under
side. I find that with this combination of parts I can vary the size of the flame
quite considerably without materially interfering with a proper combustion. The
shell S may be removed by simply elevating it off the rod S for the purpose of
cleaning it or the button or spreader.
Some of the air entering the perforations 6 of the body B rises through the
perforated plates J and ascends through the space between the wick tube and the
deflector I to the outer side of the flame. I have shown a plate K arranged in the
body B so as to divide the air entering the perforations b of the body and direct
some of it downwardly and some of it upwardly.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign Correspondent I declare that what I claim is
First: The combination with a perforated body provided at the base with
openings for the passage of a wick, of a wick tube composed of an inner and an
outer shell the inner forming a central draft flue and having openings through its
lower portion and the outer being supported above the base of the perforated body
so that a space will be left between it and said body for the passage of air
substantially as specified.
Second A wick comprising a cylindric upper portion and two isolated strips or
portions depending therefrom all being woven together in one piece.
:
Third The combination with an annular wick tube of an upwardly tapering
shell fitted in the wick tube, extending above the same, perforated throughout its
extent and having mounted upon it a button or spreader.
