Complete Specification Accepted, 28th Sept., 1888
I, CECIL HENRY FITZMAURICE, of 53 Sigden Road, Middlesex, Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is certain appliances in connection with the burner of
an oil lamp that on a tilting, jolt, or shock, such as would be given to a lamp in turning
it over accidentally or suddenly an extinguisher tube slides up the burner tube and
shuts off the access of air by which the flame is deprived of the necessary oxygen to
support combustion.
For the purpose of my invention, I surround the burner proper or wick tube with
a loose fitting tube, the base of which has spread out arms or a screen provided with a
ring or other shaped projection at the ends or edge as a weight, or they may be wires
connected to the base for the weight to ride up and so carry the loose fitting tube with
it should the lamp be tilted suddenly. The loose fitting tube is so made that the
mouth of the cone or lamp cap is completely closed by it.
The main feature of the invention is the sliding loose fitting tube and its connection
with a weight by which it is operated.
This extinguisher appliance is applicable to existing lamps.

page_text: I CECIL HENRY FITZMAURICE of 53 Sigden Road, Middlesex Engineer do
hereby declare the nature of my said 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 this invention is certain appliances in connection with the burner of
an oil lamp that on a tilting, jolt, or shock such as would be given to a lamp in
turning it over accidentally or suddenly an extinguisher tube slides up the burner
tube and shuts off the access of air by which the flame is deprived of the necessary
oxygen to support combustion.
For the purpose of my invention I surround the burner proper or wick tube with
a loose fitting tube the base of which has spread out arms, or a screen provided with
a ring or other shaped projection at the ends or edge as a weight or they may be wires
connected to the base for the weight to ride up and so carry the loose fitting tube with
it, should the lamp be tilted suddenly.
The loose fitting tube is so made that the mouth of the cone or lamp cap is
completely closed by it.
The main feature of the invention is the sliding loose fitting tube and its connection
with a weight by which it is operated.
This extinguisher appliance is applicable to existing lamps.
My invention is shown in the annexed drawings in which at Figures 1 and 2 1
show a plan and elevation of a hand lamp A with my extinguisher B encircling the
wick tube C and loosely fitted so that it has free action to slide along the tube if
the lamp be tilted beyond a given angle from any cause such as when_knocked over,
the impetus given by the fall being sufficient to start the extinguisher B to pass over
the wick and shut up the opening between the wick tube and the flame slit of the '
cap D.
The side walls of the extinguisher B are of sufficient width at the lower part where
it is weighted as to prevent the extinguisher B passing through the flame slit.
The burner tube C in this case acts as the guide to the extinguisher but according
to the arrangement shown at Figure 3 the extinguisher B is guided in its extinguishing..
motion by wires E. E. the distance to which the extinguisher finds a lodgment on the
gallery or chimney plate F being sufficient as not to interfere with the supply of air
to the flame while the lamp is burning. The wires are somewhat loose in apertures
of extinguisher B but guide wires may be dispensed with and the extinguisher B may
be provided with small rollers as at Figures 4 and 5 which when the lamp is upset
would run up the wick tube C and extinguish the flame.
The weighted sliding extinguisher B may sit upon springs G. G. as at Figures 6
and 7 so that when the lamp is upset the springs G. G. exert a lifting action to the
extinguisher B and start it in its sliding action.

page_text: Figure 8 shows a modification in which the extinguisher is composed of two metal
plates B weighted at the lower end B¹ and bearing upon springs G G so that when
the lamp is upset the springs force the extinguisher along the wick tube C and from
the springy action of the extinguisher B their upper ends close over the wick and
cut off access of air to the flame, producing an instant extinguishing action.
At Figure 8 I show the two springs G G secured to the gallery F but according
to Figure 9 the spring G is attached to the extinguisher B the action in this case
being the same.
The springy plates B B weighted as shown at Figure 8 may have plain top edges
but they may have small rollers attached as at Figure 10 so that when the extinguisher
appliance moves by impetus the two rollers H H close over the wick.
Figure 11 shows an arrangement of shutters H. H. to close over the wick
when the lamp is upset their closing being effected by the fall of the extinguisher B.
According to Figure 12 the extinguisher tube B. by its weight B¹ can be caused to
come in contact with hinged shutters or caps H, H, which otherwise lie down close
to the wick tube C but which when the lamp is upset are caused to move on their
centre pins and so close over the wick and extinguish the flame.
In all these Figures the weight is directly at the bottom of the wick tube but according
to Figure 13 the weight B₁ is at some distance from the extinguisher B and con-
nected to it by wires I the tube B acting as the extinguisher when moved along the
wick tube C.
In all the Figures here before described flat wick tubes are shown but most of the
appliances by a modification of shape can be used for lamps with round wicks as
at Figures 14 and 15 in which case I prefer to use four extinguishing plates B which
can be knocked over the wick when the lamp is upset by the sliding action of the
tube B which encircles the wick tube C under the impetus of the movable weight Bi
which is of ring form after the style indicated at Figure 13, the action in every case
being automatic and due to centrifugal thrust given to a weight during the fall of a
lamp.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1. A free fitting weight or weighted appliance B as an extinguisher and having
automatic action produced by a topple over fall of a lamp as described with reference
to Figures 1 to 10 and 13 of the annexed drawings.
2. Extinguishing a lamp flame by appliances H Figures 10, 11, 12, 14, and 15
when operated automatically by a free moving weight such as B, B', as described.
