4. To provide a wick holder capable of being moved up or down vertically by
the usual winding appliances and set itself without liability to lower or drop while
the lamp is burning.
5. To ensure a perfect capillary saturation of the wick for feeding the flame
uniformly.
For the purpose of this invention the body of the lamp is made with an internal
or central tube open at bottom but closed at top by a button or flame spreader the
stem of which serves as a plug. This tube is surrounded by another tube but at
a distance therefrom to allow of free passage of air to the inner wall of the flame.
This second tube is surrounded by a third tube to the chamber in which the wick
can be moved up or down, the third tube stopping short at the body of the lamp
to put the chamber into connection with the oil supply. This third tube is
provided with the usual winding or lift wheels and thumb button.
The third or other tube carries the gallery and chimney and if necessary the
globe holder and also a screen with conical edge for directing the air from the
gallery perforations to the outer wall of the flame in a thin strata-the body of

page_text: the screen which is heated by the flame, bringing the air to a combustible state
ready for impinging against the flame.
A float is fitted in the oil well with a pin head projecting through the body to
indicate the level of the oil.
The wick holder is a plain cylinder perforated or meshed and the wick is simply
laid against the inner surface against which rings may be fitted to press upon the
wick which rings also enable a new wick to be brought directly edge to edge with
an old wick so as to continue the use of the old wick to the last thread before the
new wick is brought into use.
The perforations or mesh of the wick holder are preferably over the whole
surface of the cylinder but they may be over a part only as desired, the perforations
or mesh corresponding to the distance to which the lift wheels are apart so that
their teeth engage in the mesh.
The perforations or mesh of the cylindrical wick holder permit of the free
passage of oil to the wick and if the perforations are all over the cylinder it
matters not how the cylinder is inserted into the lamp the lift wheels always find
a lodgement, the lift of the wick being vertical without twist and without guide
pins, studs or grooves as are usual.

the usual winding appliances and set itself without liability to lower or drop while
the lamp is burning.
5. To ensure a perfect capillary saturation of the wick for feeding the flame
uniformly.
For the purpose of this invention, (which is represented in the annexed
drawings where Figure 1 is a sectional elevation) the body A of the lamp is made
with an internal or central tube B open at bottom but closed at top by a button
or flame spreader C the stem D of, which serves as a plug. This tube B is,
surrounded by another tube E but at a distance therefrom to allow of free passage
of air to the inner wall of the flame as indicated by the arrows. This second
tube E is surrounded by a third tube F forming the chamber in which the wick G.
can be moved up or down, the third tube F stopping short at the body of the
lamp to put the chamber into connection with the oil supply. This third tube F
is provided with the usual winding or lift wheels H and thumb button or buttons,
if more than one be fitted.
The third or other tube carries the gallery I and chimney J and if necessary
the globe holder K and also a screen L with conical edge M for directing the air
from the gallery perforations N to the outer wall of the flame in a thin stratum
the body of the screen L (which is heated by the flame) bringing the air to a
combustible state ready for impinging against the flame.
A float P is fitted in the oil well Q with a pin head R projecting through the
body to indicate the level of the oil, or when the vessel is sufficiently filled.
The wick holder S shown separately in Figures 2 and 3 is a plain cylinder
perforated or meshed and the wick is simply laid against the inner surface against.
which one or more rings T T perforated or plain may be fitted to press upon the
wick G which rings also enable a new wick G¹ (shown at Figure 4) to be brought
directly edge to edge with an old wick G so as to continue the use of the old wick
to the last thread before the new wick is brought into use.
The perforations or mesh of the wick holder are preferably over the whole
surface of the cylinder but they may be over a part only as desired, the perforations
or mesh corresponding to the distance to which the lift wheels are apart so that
their teeth engage in the mesh.
The perforations or mesh of the cylindrical wick holder permit of the free
passage of oil to the wick and if the perforations are all over the cylinder it
matters not how the cylinder is inserted into the lamp the teeth of the lift wheels
always find a lodgement, in the perforations or meshes the lift of the wick being
vertical without twist and without guide pins, studs, or grooves as are usual.
In the annexed drawings I have shown a bellied lamp with my wick holder
applied but the wick holder whether of perforated or woven metal in cylindrical
form capable of receiving a tubular wick cotton, or cottons which may be made
tubular is available to all kinds of lamps in which a vertical winding up action is
required.
Figure 5 shows a perforated wick holder of flat form, and Figure 6 two
segmental perforated wick holders each of which may be raised separately by
distinct wind up appliances or if connected in any way one winding appliance will
suffice for both seguients the movement in every case being vertical.
Figure 7 shows a perforated wick holder of flat form with turned round ends
and open at one side so that the wick may be easily put in position, the wick
being then held firmly by the perforated metal and by the lips U, U. Figure 8
shows two segmental perforated wick holders of similar construction. which may
be employed in lieu of that shown at Figure 6. These may be connected, or used
in duplex fashion.
I am aware that perforated metal, or meshed gauze with the wick of oil lamps
have been already employed, but these have had an internal ferrule with tongues and
springy arms for supporting the wick, By my invention the perforated or meshed
cylinder is the wick holder, the simple ring serving to nip the cotton to prevent

page_text: the risk of it, when saturated with oil, dropping down. The cotton by expansion
while wet take sufficient hold upon the edge of the perforations and by inserting
itself therein.
Of course buttons as deflectors have been previously used in oil lamps, but in
my invention the button is carried by a central tube which is also open at the
bottom and around which the up-rising air has free play to the upper part, taking
up heat while travelling and becoming gradually hotter from the heat of the
button stem, and of the portion of the tube with which it is in contact, for better
combustion and producing clearness of flame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. In connection with oil lamps, a perforated or woven cylindrical, or other
shaped wick holder S open throughout its length and to which a vertical up and
down motion for regulating purposes is obtained by the ordinary winding wheel,
or wheels gearing into said holder as described.
2. Constructing a perforated or woven cylindrical or equivalent shaped holder
within which a circular or other wick can be fitted and be retained without other
appliances as set forth.
3. The employment of perforated or woven flat or segmental wick holders for
lamps as shown in Figures 5, 6, 7, and 8 of the annexed drawings, into which
holders the lift wheels have their action as described.

4. In a lamp of the construction hereinbefore described, the employment of
rings in connection with the perforated wick holder as shown.
5. The employment of a central tube B closed at the top by a flame spreader C
in lamps as shown on the drawings.
