Improvements in Oil Lamps.
I, JOHN THOMAS MILSON HIRCOCK, of 1 Sambrooke Place, Taylor Street,
Birmingham, in the County of Warwick, Engineer, do hereby declare the nature
of my said invention to be as follows:-
My invention has for its object improvements in oil lamps and refers particularly
to table and other such lamps for burning volatile oil and by which they are made
so that upon being overturned the light is immediately extinguished and this I
effect in a cheap and simple manner.
In carrying my invention into effect I provide a wick tabe which I mount so
that it has a rising and falling motion in the burner and to this movable wick tube
I attach the wick raising apparatus. At the top of the wick: tube & attached to
the burner I attach a second tube which surrounds the wick tube and the top of
which stands above the top of the said wick tube when the wick tube is down but
below it when the wick tube is up. One end of a lever is attached to the movable
wick tube and is pivotted centrally to the burner while the other end projects from
the burner and is flattened or otherwise formed. at the end to support a weight
which when placed upon the end of the lever retains the wick tube in its highest
position, i.e. with the top above the outer tube which is the position when alight and
in use. Upon the lamp being upset or turned over from its vertical position the
weight falls from the lever upon which the wick tube drops into the outer tube
and the light' is extinguished. The weight may be attached: to the lamp by a
chain, and a bucket or platform may be provided to catch' same when it falls. In
place of the fixed tube I may provide any suitable extinguisher such as two
pivotted vertical flaps each side the wick one or the other of which upon the wick
tube being dropped fall over the aperture and so extinguish the light.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
I, JOHN THOMAS MILSON HIRCOCK, of 1 Sambrooke Place, Taylor Street,
Birmingham, in the County of Warwick, 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 :-
My invention has for its object improvements in oil lamps and refers particularly
to table and other such lamps for burning volatile oil and by which they are made
so that upon being overturned the light is immediately extinguished and this I
effect in a cheap and simple manner.
In carrying my invention into effect I provide a wick tube which I'mount so
that it has a rising and falling motion in the burner and to this movable wick tube

page_text: I attach the wick raising apparatus. At the top of the wick tube and attached to
the burner I attach a second tube which surrounds the wick tube and the top of
which stands above the top of the said wick tube when the wick tube is down but
below it when the wick tube is up. One end of a lever is attached to the movable
wick tube and is pivotted centrally to the burner while the other end projects from
the burner and is flattened or otherwise formed at the end to support a weight
which when placed upon the end of the lever retains the wick tube in its highest
position, i.e. with the top above the outer tube which is the position when alight
and in use.
Upon the lamp being upset or turned over from its vertical position
the weight falls from the lever upon which the wick tube drops into the outer
tube and the light is extinguished. The weight may be attached to the lamp by a
chain and a bucket or platform may be provided to catch same when it falls. In
place of the fixed tube 1 may provide any suitable extinguisher such as two
pivotted vertical flaps each side the wick one or the other of which upon the wick
tube being dropped fall over the aperture and so extinguish the light.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements together with
the mode of and means for carrying the same into effect.
Figure 1., is a vertical section through one of my lamps when burning.
Figure 2., is a similar section to Figure 1 but showing the various parts with the
light extinguished.
Figure 3., is a vertical sectional elevation through Figure 1 taken at right angles
to Figure 1.
Figure 4., is a similar section to Figure 1 but showing a modification with the
lamp burning.
Figure 5, is a similar section to Figure 4 but showing the light extinguished.
In carrying out my invention I mount the wick tube A in the burner C in such
a manner that it is free to have a rising and falling movement with regard to the
burner C and to this movable wick tube A the spindle K of the wick raising
apparatus is attached being mounted in the ears or bearings a³ which are fixed
upon or form part of the wick tube A. At the top of the wick tube and fixed to
the burner the tube H is provided and surrounds the wick tube and stands above it
when the wick tube is down as shown at Figure 2 but slightly below when the
wick tube A is up as shown by Figure 1. The wick tube is retained in its highest
position as seen at Figure 1 by means of the balance weight M which is supported
by the one end of the lever F the other end of which engages with the underside
of the spindle K and the lever F, being pivotted to the burner at f1 thus supports
the wick tube A so long as the balance weight M remains in the position shown by
Figure 1 but immediately the lamp becomes tilted or turned over sufficiently for
the weight M to fall off the lever the wick tube A immediately falls by its own
weight into the position shown by Figure 2 the flame being extinguished by the
lighted part of the wick being drawn by the falling tube into the outer tube or
socket H. For additional security in the extinguishing of the flame I may provide
the extinguisher J which is pivotted at h¹ to the tube H and connected by the
wire with any part incidental to the wick tube A but preferably with the
spindle K so that upon the falling of the wick tube the cap J is drawn over
the top of the tube H thus effectually and completely shutting off the wick.
In the case of the example shown by Figures 4 and 5 where a double wick N
and N¹ and corresponding double wick tube A is used I may provide an
extinguisher consisting of the flaps j and j' which are pivoted at j and jo so
that upon the fall of the wick tube the said flaps fall over the wick as shown by
Figure 5 or in cases where the lamp falls over the flaps take the position shown
by dotted lines on either side and this arrangement of extinguisher may be
applied to single wick tubes.
To prevent any possibility of the oil working up the movable tube I provide the
collar a¹ of cork or other suitable material.

page_text: 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 :-
1st. The improvements in oil lamps substantially as and for the purpose herein
set forth and shown upon the accompanying drawings.
2nd. In oil lamps the wick tube A mounted to rise and fall a limited distance.
substantially as and for the purpose herein set forth and shown upon the
accompanying drawings.
3rd. In oil lamps the rising and falling wick tube A in combination with the
lever and weight arrangement substantially as and for the purpose herein set forth
and shown.
4th. In oil lamps the rising and falling wick tube in combination with the
extinguishing arrangements substantially as and for the purpose herein set forth
and shown.
