IMPROVEMENTS IN THE MANUFACTURE OF PETROLEUM & OTHER OIL LAMPS
Year: 1885

page_text: I, GEORGE O'CONNOR HOLLOWAY of N° 30 Worcester Street, Kidderminster
in the County of Worcester, Manufacturer do hereby declare the nature of my
invention for "IMPROVEMENTS IN THE MANUFACTURE OF PETROLEUM & OTHER
OIL LAMPS" to be as follows:-
:-
This Invention relates to Petroleum and other Lamps for burning oil; and
consists of an improved pattern of a circular Wick Holder and the method of
working the same; by means of the shape of the holder I am also enabled to
use the wick in long lengths with the result that it is always well fed and I
can burn the Petroleum or other oil contained in the Lamp until its complete
exhaustion.
The Circular Wick Holder fits on the Central Air Tube of the Lamp. I make
it with a flat circular band of metal, the top part of which I divide in equal
distances into fangs or forks which clip or hold the circular shaped wick, the
numerous small teeth at the tops of the fangs render it unnecessary to press the
wick tightly, the slightest contact being sufficient for its descending or ascending,
and as it is not pressed against the Central Tube, its feed of oil is easily obtained,
and the light remains the same when the Lamp is nearly empty as when it is full.
Attached to the metal band is a long metal strip fitted with cogs and worked with
a small notch wheel, which raises or lowers the wick always in a perfectly level
manner.
By the arrangements which I introduce there is no evaporation or escape of oil
from the body of the Lamp, and that which is produced at the Burner is conveyed
back to the reservoir by means of the funnel shaped pattern which I employ for
the reservoir.
In order to prevent the escape or waste of oil at the pinion which is the case
with almost all other Lamps, I furnish the actuating pinion and ratchet wheel, at

page_text: the point where it is connected with the body of the Lamp-with an oil stopping-
tubular metal covering with a cork washer inside, thus preventing the escape,
evaporation, or waste of oil at the pinion.
I obtain a very white flame which possesses a very strong illuminating power,
by my combination of blending the air and I use a flat central disc to divide the
flame which can be made in brass or other metal, earthenware, china, or other
hard material.
For the purpose of burning the oil in the Lamp in the open air, or in a place
exposed to a current of air, I employ, in order to prevent smoking a small metallic
Gauze covering, which I fit at the bottom of the Central Draught hole or Tube,
and in the centre of the same, thus limiting the supply of the air and causing the
flame to burn with a perfect evenness.
Dated this 8th day of September 1885.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Petroleum and other
Oil Lamps.
I, GEORGE O'CONNOR HOLLOWAY of Worcester Street Kidderminster in the
County of Worcester, Manufacturer do hereby declare the nature of my inven-
tion for IMPROVEMENTS IN THE MANUFACTURE OF PETROLEUM & OTHER OIL
LAMPS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
This Invention relates to Petroleum and other Lamps for burning Oil, and
consists of a circular Wick Holder and the means of working it; an improved
arrangement for preventing evaporation or escape of oil, an improved burner, and
an improved method for controlling the draught of Air through the Lamp.
In the annexed drawing:-
Figure A A represents the actuating pinion fitted in a small Tube, or tubular
box, having a cork or Rondelle de Liege lining and closed by a screw shaped
stopper.
Figure B B represents a section of the Lamp, the parts marked B B being the
Funnel shaped pattern of the Cap for the reservoir.
Figure C is the Gallery to carry the Glass Chimney and covering also the double
Caps G & H or G & I.
Figure D is the socket closing the reservoir.
Figure E is the central disc.
Figure F is the wick carrier.
Figure G is the extra or double Cap made to fit over the other cap as per
figure H or figure I.
By means of the covered pinion and the funnel shaped cap B I have succeeded
in preventing the sweating or evaporation of oil which is produced in all other
Petroleum Lamps; this evaporation resulting from the wick itself even when the
Lamp is not burning; petroleum being very gaseous with a tendency to evaporate
and expand. The sweating near the burner returns by the funnel cap B B to the
reservoir, and evaporation at the pinion is prevented by its small tubular covering,
This Tube being closed by a screw shaped stopper and the interior lined with cork,
Rondelle de Liege

ог Amiens" as Petroleum deteriorates all other

called
substances.
"
By means of the double Cap G fitted on to the other Caps H or I, the Air is
already heated before it reaches the burner, and thus obtains a very white and
very calm flame of a most brilliant and strong power, at the same time consuming
very little petroleum.
By means of the vase shaped socket D closing the reservoir, the wick is not
pressed or torn, and being placed on the Central Air Current Tube this wick is
not consumed.
By means of the limited course of the wick carrier the Action of the Lamp is
prevented being forced, because when the small cogs arrive at the height of the
burner, the gear has run out and the small ratchet wheel revolves by itself.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is performed, I declare that what
I claim is;
First-Tube covered Pinion A A for preventing escape or evaporation of Oil,
no other Inventor having yet succeeded in preventing evaporation from Petroleum
Lamps.
Second-Funnel shaped cap B. B to reservoir for recovery of waste or escaped
oil near the burner.
Third-Double Caps to the burner G. H. & I for heating the air before it arrives
at the burner.
