PROVISIONAL SPECIFICATION.
Improved Apparatus for Automatically Controlling the Supply of
Oll or Spirit to Lamp or Lantern Burners.
JOHN ALEXANDER SAMUELS 44 The Broadway Wimbledon, Surrey, Lamp
Manufacturer do hereby declare the nature of this invention to be as follows:
-
The object of my invention is to so control the supply to a receptacle or
receptacles from a larger cistern at a higher level (or-if under pressure-at a
lower level) in such a manner that when the smaller receptacle or receptacles has
or have received a supply to the desired extent the flow of liquid is arrested
until such time as a further supply is necessary. I effect this in the following
manner :-
The oil is conducted from the cistern through a pipe or tube to the under side of
a small vertical cylinder closed at the bottom, the connection between the pipe and
inside of cylinder is made through one or more small holes in the bottom of the
latter, the edges of which holes rise above the bottom of cylinder thus forming valve
seats, inside this cylinder I place another and shorter cylinder closed at the bottom
and of such smaller diameter as to be quite free to move up or down and to allow
a liquid to flow between the interior wall of the larger and the exterior wall of the
smaller cylinder, to the bottom exterior of this smaller cylinder I attach a disc or
sheet of india rubber or other suitable material, this-when the two cylinders are
in place substantially as described-forming a valve and closing the openings from
the supply pipe to the interior of the larger cylinder: To the top of the larger
cylinder I affix the burner in any suitable manner (but so that the top edge of the
interior cylinder cannot rise to the level of the top edge of the exterior and larger
cylinder) the wick from such burner hanging or depending into the smaller or
interior cylinder. The cistern being charged the oil passes through the pipe and
the openings in the bottom of larger cylinder thus floating the smaller cylinder as
high as it will go and then flowing over its top edge until from the access of
weight it sinks thus closing the valve or valves; the burner is supplied through
the wick from the smaller cylinder until sufficient oil has been consumed to cause
it to float again thus opening the valve or valves for a fresh supply.

COMPLETE SPECIFICATION.
Improved Apparatus for Automatically Controlling the Supply of
Oil or Spirit to Lamp or Lantern Burners.
I, JOHN ALEXANDER SAMUELS, of 4* The Broadway, Wimbledon, in the
County of Surrey, Lamp Manufacturer, 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 so control the supply to a receptacle or
receptacles from a larger cistern at a higher level (or if under pressure at a lower
level) in such a manner that when the smaller receptacle or receptacles has or have
received a supply to the desired extent the flow of liquid is arrested until such
time as a further supply is necessary.
Fig. 1 of the accompanying drawing is a vertical section of a receptacle.

page_text: Fig. 3 is a vertical section of a receptacle with a cage of perforated or woven
metal, with a burner disconnected.
Fig. 4 is a plan on line A B.
Fig. 5 is a plan on line C D.
Similar letters refer to similar parts throughout the views.
The oil is conducted from the cistern through a pipe or tube p to the under side
of a small vertical cylinder a closed at the bottom as in Fig. 1, the connection
between the pipe and inside of cylinder a is made through one or more small holes
in the bottom of the latter, the edges of which holes rise above the bottom of
cylinder a thus forming a valve seat or seats. Inside this cylinder a I provide a
smaller cylinder b' with stops t closed at the bottom herein termed the "float" and
of such smaller diameter as to be quite free to move up or down and to allow a
liquid to flow between the interior wall of the larger and the exterior wall of the
smaller cylinder; to the bottom exterior of this smaller cylinder I attach a disc of
india rubber v or other suitable material, this when the two cylinders are in place
forming a valve and closing the openings from the supply pipe p to the interior of
the larger cylinder a. To the top of the larger cylinder l'affix a collar c to receive
the burner ring in any suitable manner (but so that the top edge of the interior
cylinder 6' cannot rise to the level of the top edge of the exterior and larger cylinder)
the wick w from a burner hanging or depending into the smaller or interior
cylinder b¹.
The cistern being charged the oil passes through the pipe and the openings in
the bottom of larger cylinder thus floating the smaller cylinder as high as it will
go and then flowing over its top edge until from the access of weight it sinks, thus
closing the valve or valves. The burner is supplied through the wick or wicks
from the smaller cylinder until sufficient oil has been consumed to cause it to float
again thus opening the valve or valves for a fresh supply.
If preferable as in Fig. 3 I may construct. the outer cylinder a with a feed
chamber d for convenience of supply through pipe s¹ between pipe pand valve v,
with an air tube a' through the centre, and over the air tube a' I pass a tube which
is fixed to the centre of float b' large enough to go easily over tube a¹.
Outside
the cylinder a I attach a loose collar c on which is fixed the screwed collar to
receive the burner z. Underneath the screwed collar I fix a cage e of perforated
or woven metal with a centre tube e¹ to contain the wick and to prevent any part
of the wick interfering with the action of the float; the bottom of the said cage
acts as a stop to prevent the float rising too high.
The arrows indicate the way the oil flows from pipe p into float b¹.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In an apparatus for controlling the supply of oil or
burners, the combination of the pipe p valve seating
collar c with the float b¹ and stops t, substantially as herein
to Figs. 1, and 2, in the accompanying drawing.
