the County of Warwick, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
:
My invention has reference to lamps for burning light or volatile oils in which a
small oil container or wick dipping cup at the head of the lamp is supplied with oil
from a storage reservoir in the base or body of the lamp and my said invention
consists principally of the construction and combination of parts hereinafter
described for filling the said oil container or wick dipping cup from the storage
reservoir.
My invention is applicable to table lamps and to standard lamps or lamps
supported on the floor.
Twill first describe my invention as applied to a table lamp.
The case or body of the lamp constitutes a large storage reservoir for the oil
and above the said storage reservoir and in the axis of the lamp a small oil
container or dipping cup is supported.
In the base of the storage reservoir and communicating with it at top by a
series of perforations is a hollow cylinder in which a piston works. By means of
the said piston worked by the mechanism hereinafter described the oil in the
cylinder is forced through a supply pipe opening into the bottom of the cylinder to
the oil container or dipping cup.
The overflow pipe from the oil container or dipping cup is arranged concen-
trically around the greater part of the oil supply pipe and opens into the storage
reservoir. A valve in an expanded part of the oil supply pipe prevents the return
of the oil to the storage reservoir.
The piston
The piston in the cylinder is worked by the following mechanism.
rod passes through a long guide tube in the axis of the oil-reservoir and its upper
end is jointed to the lower end of a crank rod the upper end of which is jointed to
a crank pin on the face of a toothed wheel turning in bearings above the oil
reservoir. This crank toothed wheel gears with and is rotated by a pinion situated
above it and working on a parallel axis. The axis of the pinion projects from the
lamp case and has a square end for turning the said pinion by a key or winch. By
rotating the said pinion rotary motion is given to the crank toothed wheel and the
said wheel through its crank pin and crank rod gives a reciprocating rising and
falling motion to the piston rod and piston. Oil is thereby forced by the said
piston from the cylinder in communication with the storage reservoir and through
the oil supply pipe to the oil container or wick dipping cup.
I do not limit myself to the particular arrangement of toothed wheel and pinion

Improvements in Lamps and Candelabra for Burning Light or
Volatile Oils.
I, HERBERT ERNEST NEWTON MASON, of Henrietta Street, Birmingham, in
the County of Warwick, Manufacturer, do hereby declare the nature of my
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has reference to lamps for burning light or volatile oils in which a
small oil container or wick dipping cup at the head of the lamp is supplied with oil
from a storage reservoir in the base or body of the lamp; and my said invention
consists principally of the construction and combination of parts hereinafter
described for filling the said oil container or wick dipping cup from the storage
reservoir.
My invention is applicable to table lamps and to standard lamps or lamps
supported on the floor."
I will first describe my invention as applied to a table lamp.
The case or body of the lamp constitutes a large storage reservoir for the oil and
above the said storage reservoir and in the axis of the lamp a small oil container
or dipping cup is supported. In the base of the storage reservoir and communi-
cating with it by a series of perforations is a hollow cylinder in which a piston
works. By means of the said piston worked by the mechanism hereinafter described
the oil in the cylinder is forced through a supply pipe opening into the bottom of
the cylinder to the oil container or dipping cup. The overflow pipe from the oil
container or dipping cup is arranged concentrically around the greater part of the
oil supply pipe and opens into the storage reservoir.
The piston in the cylinder is worked by the following mechanism.
The piston rod passes through a long guide tube in the axis of the oil reservoir
and its upper end is jointed to the lower end of a crank rod the upper end of
which is jointed to a crank pin on the face of a toothed wheel turning in bearings
above the oil reservoir. This crank toothed wheel gears with and is rotated by a
pinion situated above it and working on a parallel axis. The axis of the pinion
projects from the lamp case and has a square end for turning the said pinion by a
key or winch. By rotating the said pinion, rotatory motion is given to the crank
toothed wheel and the said wheel through its crank pin and crank rod gives a
reciprocating rising and falling motion to the piston rod and piston. Oil is thereby
forced by the said piston from the cylinder in communication with the storage
reservoir and through the oil supply pipe to the oil container or wick dipping cup.
I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
Figure 1 represents in vertical section a table lamp containing my improvements;
Figure 2 represents in vertical section a portion of the same taken in a plane at
right angles to that in which the section Figure 1 is taken; and Figure 3 repre-
sents in section a portion of the concentric oil supply and overflow pipes of the
lamp drawn to a larger scale.
The saune letters indicate the same parts in the several figures of the drawing.
a is the storage reservoir for the oil filled at an opening in the top of the said
reservoir and is the small oil container or wick dipping cup at the top of the
lamp is the hollow cylinder in the base of the storage reservoir a and d is. the
piston working in the said cylinder and actuated in the manner hereinafter
described. By means of the perforations at a communication is established between
the storage reservoir and cylinder e for the passage of oil from the former into
the latter is the oil supply pipe through which oil is forced by the action
of the piston d in the cylinder c. The said oil supply pipe jf opens at bottom
into the cylinder c and passing upwards enters the wick dipping cup or oil
container through the tubular base of the same; g² is the overflow pipe from
:

page_text: the oil container b. It will be seen that the said overflow pipe is arranged con-
centrically about the greater part of the oil supply pipe and opens at into the
storage reservoir a. The tops of the said concentric oil supply and overflow pipes
are connected together by the hollow perforated sphere the oil from the supply
pipe passing out into the container by the perforations in the said sphere.
Portions of the top of the overflow pipe g² between it and the sphere are cut away
at to permit of the overflow oil entering the said overflow pipe and returning by
the said pipe to the storage reservoir as best seen in Figure 3. In the base of the
wick dipping cup or oil container is a tubular passage 62 for receiving the
concentric oil supply and overflow pipes, g
For the purpose of adjusting the height of the concentric oil pipes in the wick
dipping cup or oil container 6 I make the upper parts of the said pipes telescopic
in the manner best seen in the enlarged view Figure 3.
That is to say, the upper
part 2 of the overflow pipe is made separate from the lower fixed part 9 of the said
pipe and the two parts are connected together and a tight joint made between
them by means of the tubular collar or sleeve m the lower part of which is soldered
to the part of the overflow pipe. Within the upper part of the collar or
sleeve m the adjustable upper part 2 of the overflow pipe is capable of sliding.
Similarly the upper part 2 of the oil supply pipe is separate from the lower fixed
part and the two parts are connected by the tubular collar or sleeve soldered to
the lower part the upper adjustable part 2 being capable of sliding in the said
collar or sleeve n. By sliding the pipes and within their respective sleeves n
and m the height of the oil supply and overflow pipes in the wick dipping cup or
oil container may be adjusted.
As the two pipes are connected together at top by the perforated sphere i the
raising or lowering of the outer pipe in its sleeve m at the same time raises or
lowers the inner pipe in its sleeve n.
The adjustable upper parts 2 and g² of the oil supply and overflow pipes are
fixed in their adjusted position by means of the semi-circular clips or pummels p², p²
pressed against the outer pipe by the screws p, passed from the outside of the
lamp case as represented in Figure 1. By relaxing the screws P, p the grip of the
clips or pummels p², p² on the pipe is removed and the concentric sliding parts f², 2
of the two pipes may be adjusted. A. liquid tight joint between the tubular bottom
of the oil container and the concentric pipes passing through it is formed by
plaster of paris or other cement.
:
The piston d by the reciprocating notion of which in the cylinder e the oil in the
said cylinder is forced through the oil supply pipe ff into the wick dipping cup or
oil container b is actuated by the following mechanism is the piston rod and d³
is the crank rod jointed to its upper end. The said piston rod works in a long
fixed guide tube y slotted on opposite sides to permit of the motion of the crank
rod . The long fixed guide tube g is made preferably in two parts their hollow
or concave faces being presented to each other and fixed at such a distance apart as
to leave continuous slots on opposite sides for the crank rod d³ to work in. The
upper end of the crank rod is jointed to the crank pin on the face of the
toothed wheel the axis of which turns in the bearing at supported at the top of
the case or body of the lamp. The crank-toothed wheel gears with and is
rotated by the pinion s situated above it and working on a parallel axis s2, the said
axis of the pinion being worked from outside the lamp case by the key t taking upon
a square end on the axis of the pinion.
When it is wished to fill the dipping cup or oil container b with oil from the
storage reservoir a the pinion s is rotated by its key t and a rotary motion given to
the larger crank wheel . This motion is transmitted through its crank pin and
crank rod d³ to the piston rod d² and piston d and a reciprocating motion thereby
given to the said rod and piston and the oil in the cylinder supplied thereto from
the storage reservoir a is forced by the said piston from the said cylinder up the
supply pipe to the oil container or wick dipping cup 6 the surplus oil supplied

page_text: to the dipping cup being returned to the storage reservoir through the overflow
pipe g, g².
I do not limit myself to the particular arrangement of toothed wheel and pinion
described and represented for working the piston as other equivalent arrangements
of gearing may be used for that purpose.
In standard lamps the cup or oil container at the top of the standard in com-
munication with the cylinder in. the storage reservoir may have a series of radial
arms or branches with dipping cups at their outer ends which dipping cups supply
oil to the wicks carried by them.
Having now particularly described and ascertained the nature of my invention,
and the manner in which the same is to be performed, I declare that I claim as my
invention of improvements in those kinds of lamps and candelabra for burning light
or volatile oils in which an oil container or cup at the head of the lamp is supplied
with oil from a storage reservoir in the case or body of the lamp :-
:-
First The arrangement or combination of parts substantially as hereinbefore
described and illustrated in the accompanying drawing for actuating the piston by
which the oil from a cylinder in communication with the storage reservoir is forced
through a supply pipe to the oil container or wick dipping cup.
SecondlyThe combination or arrangement of the concentric oil feeding and
overflow pipes of the lamp hereinbefore described and illustrated in the accom-
panying drawing.
Thirdly-The combination with the concentric oil feeding and overflow pipes of
the lamp of an oil container or wick dipping cup provided with a tubular bottom
through which the said pipes pass to the oil container or wick dipping cup as
hereinbefore described and illustrated in the accompanying drawing.
Lastly The telescopic arrangement hereinbefore described and illustrated in
the accompanying drawing of the upper parts of the concentric oil feeding and
overflow pipes of the lamp for the purpose of adjusting the height of the said pipes
in the oil container or wick dipping cup.
