Improvements in or connected with Extinguishers for Lamps.
I, SALOMON FALK, of 83, Farringdon Road, in the County of London, 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:-
My invention relates to lamp extinguishers of that kind wherein two pivotted
shutters are employed, which, in order to extinguish the flame, are closed together
in order to form a cap, and which are designed to operate automatically to extinguish
the flame in case the lamp is overturned.
Now the object of my invention is to provide means for rendering the automatic
action of such extinguishers more certain than heretofore and to this end I apply
weights to the said shutters in the novel manner hereinafter described.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a side elevation of a lamp extinguisher having my improvements
applied thereto :
Figure 2 is also an elevation of the same, but at right angles to that shewn in
Figure 1, and,
Figure 3 is a plan :
Figure 4 is a sectional elevation shewing my improved extinguisher applied to
a lamp burner; and,
Figure 5 is a similar view illustrating the operation of the extinguisher in case
the lamp is overturned.
a, a are the two shutters which are pivotted at b, b upon a frame c adapted to be
fitted onto the wick-tube d. e, e are arms which are formed upon the shutters and
which are provided with feet f,f which form stops to prevent the shutters from
opening too far as will be readily understood by reference to Figure 4.
I, 9 are
the weights which I employ for ensuring the closing of the shutters in case of
over-turning, the said weights being fixed to levers, pivotted to lugs upon the
ends of the arms e, e, the pivots being placed at an angle to the outer faces of the
shutters so that when the levers with their weights rotate upon the said pivots,
the weights will come into contact with the shutters, as indicated by the dotted
lines in Figure 4. Stops i, i are formed upon the lugs to which the levers h, h are
pivotted in order to prevent the weights from moving below their horizontal
position as indicated most clearly in Figure 2.
In case a lamp provided with the arrangement hereinbefore described should be
overturned, the weighted lever h in conjunction with the uppermost shutter would
rotate upon its pivot and strike the back of the said shutter in order to assist or
accelerate the closing of the same against the opposite shutter, as shewn in
Figure 5, should the said shutter move rather slowly.
It is obvious that a lever may be arranged in conjunction with the shutters in
order to close the same by hand if desired.
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. The combination with a lamp extinguisher having two pivotted shutters
adapted to close one upon the other, of weights fixed to levers pivotted upon the
shutters in such a manner that in case the lamp is overturned the said weights
will strike the shutters in order to accelerate or assist the movement of the same,
substantially as described.
