I SAMUEL ALBERT JOHNSON of 24 Glengall Road Millwall in the Parish of
Poplar, Marine Engineer, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN OR CONNECTED WITH LAMPS SPECIALLY SUITABLE FOR ENGINE
ROOM PURPOSES FOR SHIPS USE ALSO FOR LAND SERVICE" to be as follows:-
By my Improvement I take and provide a chamber or receptacle of suitable
material and form or shape, to the upper portion of which an Oil Chamber or
receiver is formed and at the bottom or lower portion I form a partition or space,
which I designate as the "wick Chamber, at the upper portion of the said "wick
chamber" I provide a suitable Valve which is so adjusted and capable of being
regulated for the admission of the necessary amount of Oil or Liquid at will, to
increase the light or regulate the same, by means of an outward or regulating hand
screw to which it is connected for that purpose.
From the aforesaid "wick chamber "I provide a spout or connection (or spouts
or connections) to which the wick is suitably led and then ignited; at the rear of
the said "wick chamber" or at side thereof I also provide a screw cap for the
purpose of inserting the wick into the chamber and also adapted for cleansing
purposes.
I provide for the support of the Lamp by any suitable adjustment according to
the purpose for which it may be intended.

for Engine Room Purposes for Ships' Use, also for Land
Service.
I, SAMUEL ALBERT JOHNSON of 24 Glengall Road Millwall in the Parish of
Poplar, Marine Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
. By my Invention I take and provide a chamber or receptacle of suitable material
and form or shape, to the upper portion of which an Oil Chamber or receiver is
formed and at the bottom or lower portion I form a partition or space which
I designate as the " Wick Chamber," at the upper portion of the said "Wick
chamber" I provide a suitable Valve which is so adjusted and capable of being
regulated for the admission of the necessary amount of Oil or Liquid at will, to
increase the light or regulate the same, by means of an outward or regulating
hand screw to which it is connected for that purpose.
From the aforesaid "Wick chamber " I provide a spout or connection (or spouts
or connections) to which the wick is suitably led and ignited at will; at the rear
of the said wick chamber or at the side thereof, I also provide a screw cap for the
purpose of inserting the wick into the chamber and also adapted for cleansing
purposes.
I provide for the support of the Lamp by any suitable adjustment according to
the purpose for which it may be intended.
In the accompanying Drawing, I have shewn for the purposes of illustration
a class of Lamp according to my Invention most suitable for Engine room or
other purposes, in which Figure 1, exhibits a section, Figure 2, a plan and
Figure 3, an elevation of a Lamp not requiring either shade or case being of
the kind known as open hand Lamps. Figure 4, is a section taken at A. A of the
elevation Figure 5, exhibiting a somewhat similar class of Lamp slightly modified
in form and shape, but suitable for reflecting, or shut up or closed Lamps.
In each view the following figures refer to like or corresponding parts, A being
a chamber or receptacle of suitable form shape or capacity intended to receive the
Oil or Liquid contents into which it is fed-or supplied by unscrewing or with-
drawing the plụg B. At the bottom or lower portion of the chamber A, I provide
a partition or space C, intervening between the lower or bottom part of the body
of the Lamp and forming a second chamber or receptacle D, beneath, intended to
contain the wick which is fed therein-or supplied through the opening by removal
of the screw cap provided for the purpose as at E, also for cleansing and recharging
the wick which can be very readily done. Connected to or forming part of the
aforesaid wick chainber " or receptacle D, I provide a spout or connection F in
the case of open Lamps (or spouts or connections as the case may be) of suitable
form to which the wick is led and ignited therefrom. I form an opening G in the
partition or space C, of suitable size and form so as to connect the upper chamber
or receptacle A, with the lower or bottom space or wick chamber D.

page_text: The opening G, is also so formed as to receive a conical or other form of Valve H,
working freely therein attached to a spindle J, and capable of being regulated at
will by means of an outward or regulating screw K, to which it is connected and
so adjusted that when turned either to the left or right as to permit a sufficient
quantity of Oil or Liquid, as the case may be, so as to either increase the feed or
supply into the chamber D and regulate the Liquid or illuminant or shut off the
supply thereto as may be required.
This Invention may be applied in various ways to suit different classes and forms
of Lamps of all kinds and suitable for the same with slight modifications, and
increase the lighting power of existing Lamps to which it may also be easily
applied.
Having now particularly described and ascertained the nature of my said
Invention and illustrated the same, and in what manner the same is to be
performed I declare that what I claim is :-
The forming of a division space by means of a partition between the Oil or Liquid
chamber or receptacle and the Wick or lower chamber, likewise the conical or other
suitable form of Valve capable of being caused to regulate the admission of the
necessary amount of Oil or Liquid into the said Wick or lower chamber as the
case may be either to increase, decrease or shut off the supply at will and so
regulate the Light; substantially in the manner herein described and set forth.
Dated this 25th day of December 1885.
