"
PROVISIONAL SPECIFICATION left by the said William Phillips Thompson

WILLIAM PHILLIPS THOMPSON. of the firm of W P. Thompson & Co Patent
"IMPROVEMENTS
Agents 6 Lord Street. Liverpool in the county of Lancaster.
A communication
IN WICK HOLDERS FOR RAILWAY CARRIAGE AND OTHER LAMPS.'
from Joseph Scrafton a resident of Lahore, in the Empire of India.
"
The object of this invention is to provide a wick holder for the lamps of railway
carriages and those used in other situations, where they are liable to the shaking
or vibration consequent upon their situation, and it has principally been designed
for use with the lamp for railway carriages, which is described in the specification of
letters Patent N° 3829 of 1880.
In the wick holders at present in use the wick is liable to slip, and by the use of
this invention slipping is prevented. There is arranged in that part of the holder
through which the wick passes, a series of small pins fixed rigidly to the side
plate of the holder. To the end of the holder a second plate is hinged which is
closed down upon the wick and forces the pins or points on the opposite plate into
the wick fabric, and thus securely holds it in position. This plate may be held in
position by a spring in the hinge or by other suitable spring or means, as found
desirable. At either end of the holder are placed wings or lugs, which serve to
secure the holder to the lamp.
To raise the wick in the lamp the hinged pinte is opened and the wick taken off
the pins and replaced in the required position, or the holder may be placed in a
slide in or below the burner, and raised or lowered therein as the height of the
wick requires changing.
The invention may be found applicable to other lamps than those above named,
wherein a wick of woven fabric is used to convey the oil to be burned.

by the said William Phillips Thompson in the Patent Office on the
30th January 1884.
WILLIAM PHILLIPS THOMPSON, of the firm of Wm. P. Thompson and Co., Patent
Agents, 6 Lord Street, Liverpool, in the county of Lancaster "IMPROVEMENTS
IN WICK HOLDERS FOR RAILWAY CARRIAGE AND OTHER LAMPS A communication
from Joseph Scrafton, a resident at Lahore in the empire of India.
"
The object of this invention is to provide a wick holder for the lamps of
railway carriages and those used in other situations where they are liable to the
shaking or vibration consequent upon their situation, and it has principally been
designed for use with the lamp for railway carriages which is described in the
specification of Letters Patent N° 3829 of 1880.
In the wick holders at present in use the wick is liable to slip, and by the use
of this invention slipping is prevented. There is arranged in that part of the
holder through which the wick passes a series of small pins fixed rigidly to the
sido plate of the holder. To the end of the holder a second plate is hinged which
is closed down upon the wick and forces the pins or points on the opposite plate
into the wick fabric and thus securely holds it in position. This plate may be held
in position by a spring in the hinge or by other suitable spring or means as found
desirable. At either end of the holder are placed wings or lugs which serve to
secure the holder to the lamp.
To raise the wick in the lamp the hinged plate is opened and the wick taken off
the pin and replaced in the required position, or the holder may be placed in a
slide in or below the burner and raised or lowered. therein as the height of the
wick requires changing.
The invention may be found applicable to other lamps than those above named
wherein a wick of woven fabric is used to convey the oil to be burned.
In the drawing, A is the wick holder. B the movable or hinged piece as
described. It will be obvious however that for different kinds of lamps different
modifications may be required, and for some purposes I may prefer to have both
sides hinged to a standard at the end and open so as to leave the wick perfectly
free. Each side in that case can bo spiked with spikes entering the wick just
sufficiently to hold it, yet so short that they will not drag in the wick and prevent
the holder opening. The spikes can be sharp ridges instead of spikes if desired,
but spikes are preferable.
Having now described my invention and the best mode known to me of carrying
it into effect, I wish it to be understood that I am well aware that a fluted or
toothed wheel has long been used in regulator lamps to raise the wick, and I make
no claim for such, but that what I do claim under the Letters Patent is :-
Forming the wick holder (for railway carriage and other lamps) with one or
more spikes or sharp projections penetrating into the wick, but capable of being
withdrawn by their own movement or that of the wick from the wick when the
relative position of the wick requires altering.
In witness whereof I the said William Phillips Thompson have hereunto set
my hand and seal this twenty ninth day of January in the year of our Lord one
thousand eight hundred and eighty four.
