page_text: An Improvement in or Pertaining to Lamps.
I WILLIAM KILSBY of 1 Harewood Terrace Southall in the county of Middlesex
Jeweller 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 so to fit lamps and with such an appliance or device
that when the same are overturned or even dangerously inclined the flame or flames
of these lamps shall immediately be extinguished and therefore such lamps as are fitted
with this my invention will be free from the great evil commonly experienced with
and in portable or unfixed lamps and will be very safe in the using.
"
In the accompanying drawing I have shewn my invention as applied to an
ordinary lamp with one burner or wick holder. Figure 1 is a perspective view of the
burner of a lamp with my appliance in such position that the flame can be maintained
therein and Figure 2 is a similar perspective view of the same with my appliance in
such position as to extinguish the flame. Figure 3 is an elevation of the upper part
of the tube or wick holder of the lamp with my appliance thereon and Figure 4 is a
transverse vertical section of the same.
Round and on the tube or wick holder A I construct and fit a sleeve B preferably
made of sheet metal which sleeve B is capable of sliding up and down the tube A and
may be of any convenient length and in its lowest permitted position the upper edge
of the sleeve B is on a level with the upper edge of the tube A or thereabouts. On
one side of the upper part of the sleeve B is preferably cut away the desired depth
and in this part if any so cut away is horizontally pivoted a plate C corresponding in
size and shape thereto to which plate Ca spring is applied in such wise as normally
to force the upper edge of the same over against the opposite side of the sleeve B.

page_text: A very convenient and cheap method of effecting this object is shewn in Figure 3
as also in Figure 5 which is an elevation on an enlarged scale of this plate C.
According to this method the plate C extends below the pivots D thereof and
this extension is so formed and bent that a tongue C¹ constructed of the same
piece of material forms a spring the end whereof presses against the outer surface
of the sleeve B thereby forcing or tending to force the upper edge of the plate C
over against the opposite side of the sleeve B as is desired. This sleeve B with its
spring plate C if any constitutes and is my extinguisher and it is obvious that when
the extinguisher is in its lowest permitted position as shewn in Figure 1 the tube A
compels the spring plate C to remain parallel or thereabouts with the opposite side
of the sleeve B and therefore the flame can be maintained but when the extinguisher
rises above the upper edge of the tubo A as shewn in Figures 2, 3 and 4 the upper
edge of the spring plate C presses against the opposite side of the sleeve B and
extinguishes the flame the more surely and efficiently though the same effect is
produced by the sleeve without the spring plate.
The extinguisher is actuated by a suitable spring in such wise that it normally
retains and remains in the upper or elevated position shewn in Figures 2, 3 and 4 in
and by which the flame is extinguished.. I show in Figures 1 and 2 a very convenient
and cheap method of effecting this object wherein a wire spring E is mounted on a
bracket in the lamp gallery which spring E passes through an eye or under a
projection fitted to the sleeve B or as is preferable through an eye G stamped out of
the body of the sleeve B and turned back as shewn in these Figures.
A pull His attached either to the sleeve B or as is preferable when the apparatus
is constructed and fitted as shown in the drawing to the end of the spring E which
pull H passes freely out through an aperture K properly formed therefor in the lower
part of the lamp gallery and when this pull H is actuated to draw down the sleeve B
against the spring so as to allow the lamp to be lighted this pull H is retained and
held in any convenient and suitable manner in or by and on an arm L fitted on
the outside of the lamp gallery below the aperture K and a weight M of any size
and shape is attached or connected to or formed with this pull H at or near the
end thereof. The manner or method in and by which the pull His retained and
held is so arranged that while the lamp is in its proper vertical position the
arm L continues so to retain and hold the pull H but when the lamp is overturned
or even dangerously inclined the weight M shall immediately release the pull H
allowing the sleeve B to slide up the tube A and extinguish the flame as is herein-
before described.
I shew in the drawing two very convenient and suitable arrangements for retaining
and holding the pull. In Figures 1 and 2 the end of the arm L is turned up and a
claw N is formed thereon or therein in which the pull H can be placed the weight M
in this case serving not only to keep the pull H down in the claw N but also as a stop
to prevent the pull H being drawn through the claw N. In Figure 6 the pull H
terminates with an angled bar or piece P which engages over the end of the arm L
the weight M in this case serving only to keep the pull H down on the arm L. Any
other usual and suitable device or arrangement may also be employed for this purpose.
For example a pin or stud may be fitted to the weight to enter an bole made therefor
in the arm or vice versa. In all cases while the lamp is in its proper vertical position
the weight assists in retaining and holding the pull on and by the arm but when this
proper vertical position of the lamp is not maintained the weight immediately draws
the pull away from the arm thereby releasing the same.
In the same manner this my invention can be fitted to lamps with double or duplex
or other burners as indeed is sufficiently obvious a sleeve being fitted as hereinbefore
described to each burner and corresponding with the same and a separate pull and
weight and arm may be arranged for each sleeve or the pulls of the several sleeves
may be connected together so that one weight and one arm would control all the pulls
or the sleeves themselves may be connected together so that one pull one weight and
one arm would govern all the sleeves.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
1. The arrangement and combination of parts and appliances constituting my
improvement in or pertaining to lamps substantially as herein before described and
shewn in the accompanying drawing.
2. In a lamp the combination with the tube or wick holder of the sleeve actuated
by a spring the pull by which the sleeve is governed the arm by which the pull is
retained and the weight by which the pull is released substantially as and for the
purpose hereinbefore described and declared.
