Improvements in Lamps and in Apparatus for Extinguishing
the same.
I, JULIUS MATTON of 7 St. Mary Axe in the City of London Merchant do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to construct a stand swinging or bracket lamp which
will be automatically extinguished when upset and which can also be extinguished by
slightly raising the body of the lamp out of the stand, swinging support or bracket in
which it rests, and thus save the trouble of turning down the wick.
The invention consists of an extinguishing disc formed of any ordinary spreader
provided with a double rim the said disc being attached to a vertical rod sliding in
suitable guides in the interior of the lamp. The said rod is kept down by the tension
of a spiral or other spring and terminates in a knob.
Within the lamp support a plate is so arranged that when the lamp is placed within
the support the knob comes in contact with the plate the weight of the lamp overcomes
the tension of the spring and the extinguishing disc is raised vertically so as to be
clear of the wick.
My invention can also be applied to ordinary lamps which are not placed in a
support or stand, in which case it would be necessary to fit the lamp with some means
for keeping the vertical rod from being acted upon by the spring when it is
required to lift the lamp from the table, but these means form no part of my
invention.

Improvements in Lamps and in Apparatus for Extinguishing
the same.
I, JULIUS MATTON of 7 St. Mary Axe in the City of London Merchant 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 this invention is to construct a stand, swinging or bracket lamp which
will be automatically extinguished when upset and which can also be extinguished by
slightly raising the body of the lamp out of the stand, swinging support or bracket in
which it rests and thus save the trouble of turning down the wick.
The invention consists of an extinguishing disc formed of any ordinary spreader
provided with a double rim the said disc being attached to a vertical rod sliding in
suitable guides in the interior of the lamp. The said rod is kept down by the tension
of a spiral or other spring and terminates in a knob. Within the lamp support a plate
is so arranged that when the lamp is placed within the support the knob comes in
contact with the plate, the weight of the lamp overcomes the tension of the spring.
and the extinguishing disc is raised vertically so as to be clear of the wick.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings in which similar letters indicate corresponding parts throughout.
Fig. 1 is a sectional elevation of a circular wick stand lamp fitted with my
invention.
Fig. 2. is a similar view shewing the extinguisher applied.
Fig. 3 shows my invention as applied to a burner for flat wicks.
Referring to Figures 1 and 2 The stand A. is provided with a plate or other
projecting piece B upon which the end of the vertical rod D rests when the lamp is
upon the stand as shown in Figure 1.
The spring E works upon a collar F upon the rod D and a shoulder G attached
to the interior of the central vertical tube. When the lamp is in the stand A the end
of the vertical rod D is held up by the projecting piece B and the distance between
the collar F thereon and the shoulder G is shortened and the spring placed under
tension the extinguishing disc or cap H is thus held above the flame.
The disc H is provided with a double rim J, K, for the purpose of fitting over the
wick Land thereby extinguishing the flame. If the end C of the vertical rod D is
removed from the projecting piece B the tension of the spring E will cause the said
rod D to bring down the disc H upon the wick L and the encircling double rim J. K.
will completely extinguish the flame.

page_text: If therefore the Lamp is upset the body M will through its weight fall out of the
stand A and it is obvious that the lamp will be extinguished by the action of the
spring E upon the collar F. The same action will ensue when the body M of
the lamp is lifted out of the stand A thus enabling one to extinguish the lamp when
required.
In Fig. 3 my invention is shown as applied to a lamp fitted with a flat wick or
wicks the action of the rod D is in this case the same as already described but in place
of the disc H I substitute a bell crank N provided with a right angled arm P. pivotted
at to some fixed part of the lamp, so that the vertical displacement of the
rod D will cause the arin P to close over the top of the wick and so extinguish the
same.
My invention can also be applied to ordinary lamps which are not placed in a
support or stand, in which case it would be necessary to fit the lamp with some means
for keeping the collar F of the rod D from being acted upon by the spring E when
it is required to lift the lamp from the table, but these means form no part of my
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The construction of a lamp fitted with a spring E and vertical rod D for the purpose
of extinguishing the lanp when the end of the rod D is displaced from the projecting
piece B upon the stand or other support A of the lamp substantially as herein before
set forth and illustrated in the accompanying drawings.
