page_text: WILLIAM HENLEY No. 100 Brocklehurst Street New Cross Lamp Maker do hereby
declare the nature of this invention to be as follows:-
The reservoir is made in two parts or tanks. The outer tank containing oil and
feeder. The inner tank containing burnner. These tanks are connected by a flat
tube at bottom. Between the inner and outer tanks is fitted an inverted tray for
regulating cold air to burnner and tanks, also to prevent waste of oil in trimming.
On the inverted tray is fitted a platform for supporting chimney. The chimney
consisting of a square tin case with conical top with peices of moveable glass inserted.
The chimney being hinged on the platform to keep the burnner in its proper position.
The tube containing the wick is fitted with a gauge to trim lamp cotton the proper
height.

Improved Petroleum Lamp for Railway Signal or other Lighting.
I, WILLIAM HENLEY 100 Brocklehurst Street, New Cross, Lamp Maker, 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 :-
The object of my Invention is to construct a lamp for signalling, or other purposes,
in such a manner that signalling by means of different colored lights may be carried
out in a simple and effective manner, and also I provide a method of keeping the oil
reservoir cool, a free air passage to the flame, and a ventilating arrangement by which
the products of combustion are carried away without the possibility of down draught.
A lamp constructed according to my invention also includes a wick gauge to facilitate
the accurate trimming of the wick.
In order that my Invention may be the better understood I have appended the
accompanying three sheets of drawings, in which Figure 1 represents a sectional
elevation of a lamp constructed according to my Invention, Figure 2. a plan of the
same with the cover removed. Figure 3. a sectional plan of the oil reservoir.
Figure 4 is a sectional elevation of a wick tube, and part of flame cone, Figure 5 a
sectional plan of the same, Figure 6 is an elevation of a triangular chimney case for
showing the light through one or two colored glasses at will this being an alternative
method, Figure 7 is a plan of a lamp fitted with this chimney case the cover being
removed and Figure 8 is an elevation of the aforesaid triangular case, showing the
latch arrangement to be hereinafter fully described.
In carrying out my Invention I construct an oil reservoir A, shown in plan
Figure 3 with a hollow bridge B across the central space, a smaller tank C being
formed in the centre of said hollow bridge for the purpose of holding the outer wick
or burner tube D, and also forming a bearing for the stem socket E which supports
the hinged chimney case F and allows of its free revolution, independent of the
burner tube G which is fitted by screwing, or by an equivalent method within the
outer tube D, before refered to. The burner tube G which holds the wick H is
provided with a flange a resting upon the flanged bush b which serves to make an oil
tight connection between the burner tube G and inner tank C. The burner cone dis
arranged to fit over the burner tube G and a wick guage e c' is attached to the top of
the latter in order to facilitate the proper burning of the wick. The chimney case F
is formed either square, as shown by Figures 1 and 2 or triangular as shown in
Figure 6, 7 and 8 which is an alternative arrangement or disposition. Glass discs 1
are fitted into the orifices round the sides of the revolving case F, said glass discs
being of various suitable colors for signaling purposes, and are easily replaced in case
of breakage. The case F is hinged at h to the standards J supporting it, and is
secured by a spring catch K, said arrangement allowing of the chimney case being
lifted or thrown back upon the hinge when the lamp requires to be trimmed or
cleaned. A conical chimney L is fitted to the top of the chimney case F and is
provided at the upper extremity with a slot into which engages a cross bar M

page_text: connected across the cover N. Said cover or hood N fits within the lantern case o
and is held in position therein by two catches P P₁ Figures 2 and 7. This arrange-
ment allows of the whole chimney case F in connection with the cover N being
revolved by the looped handle p so that the different colored glasses may be brought
into position at will, the light being varied in color accordingly through the bulls eye
lens R and the light being shut off by turning the chimney case F so that the blank
side carrying the catch K is brought round to intervene between the flame and the
lens R. A double hood Q upon the cover N serves to allow of perfect ventilation by
affording free egress for the heated air and the products of combustion, and preventing
"down draught." I also provide a platform S, fitted to the standards J of the
chimney case F, the object of said platform S being to prevent waste of oil, and also
to regulate the admission of air to the flame, the supply of air passing through the
annular space T between the inner oil tank C and the outer oil tank A, a space e
between the oil tanks and the lantern allows of the free circulation of the air that is
necessary for perfect combustion.
It will be seen that when the improved lamp made according to my Invention is in
use, combustion is perfectly effected, the result being a clear and smokeless flame.
The requisite quantity of air is supplied to the burner through the air passages e and T,
the arrows in Figure 1 indicating the direction of the current of air. The heated air
and products of combustion ascend through the conical chimney L into the hood Q
whence egress is afforded by the double sheath cup ff forming the outer case of the
hood and a steady flame may thus be maintained in a high wind, because the
ingress of down draught is prevented, without impairing the ventilation of the lantern.
The wick guage c c¹ Figure 1 allows of the trimming of the wick to a suitable height,
to be properly performed and waste of oil is prevented by the platform S, which also
serves the double purpose of a shield to interpose between the stratum of hot air
above the burner, and the oil reservoirs, and thus eliminating a source of danger.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is:
Firstly. The improved petroleum lamp with plates of plain or colored glass adapted
to and capable of being removed from the casing substantially as herein described and
shown in the accompanying drawings.
Secondly. In a petroleum lamp the double tank reservoir, with intermediate air
channels substantially as herein set forth.
Thirdly. In a Petroleum lamp the platform or tray used as a regulator for air
supply and as an intermediate non-conducting screen to protect a hydro-carbon oil
used in the double tank reservoir from the heat arising from combusting substantially
as herein set forth.
Fourthly. In a Petroleum lamp the wick guage c c' as and for the purposes herein
set forth.
