PROVISIONAL SPECIFICATION.
Improvements in Lamps.
1, SALOMON FALK, of 83, Farringdon Road, in the County of London, Lamp
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to lamps provided with extinguishers and especially to
lamps having round wick burners, and the object of my present invention is to
provide for operating the extinguishers of such lamps automatically.
In carrying out my invention I arrange in conjunction with the extinguisher tube
or tubes a spring which tends to raise the extinguisher to extinguish the flame.
During the time the lamp is burning, the extinguisher is held down against the
pressure of its spring by means of a lever and a catch which when released allows
the extinguisher to rise under the action of the spring.
In order to release this extinguisher lever in case the lamp is upset I arrange in
conjunction with the catch a lever which I term the releasing lever carrying a
weight or adapted to be acted upon by a weight in such a manner that the catch
will disengage from the extinguisher lever either when the weight is displaced or
when the weight rolls against the releasing lever.
My improvements in operating extinguishers are very advantageously employed
in conjunction with the extinguisher forming the subject matter of application
No. 22514 of 1892.

COMPLETE SPECIFICATION.
Improvements in 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 lamps provided with extinguishers and especially to
lamps having round wick burners, and the object of my present invention is to
provide for operating the extinguishers of such lamps automatically.
In carrying out my invention I arrange in conjunction with the extinguisher tube
or tubes a spring which tends to raise the extinguisher to extinguish the flame.
During the time the lamp is burning, the extinguisher is held down against the
pressure of its spring by means of a lever which I term the extinguisher lever and
a catch which when released allows the extinguisher to rise under the action of the
spring.
In order to release this extinguisher lever in case the lamp is upset I arrange in
conjunction with the catch a lever which 1 term the releasing lever carrying a
weight or adapted to be acted upon by a weight in such a manner that the catch
will disengage from the extinguisher lever either when the weight is displaced or
when the weight rolls against the releasing lever.
To enable my invention to be fully understood I will describe my improvements
as applied to the extinguisher forming the subject matter of application No. 22514
of 1892 and in the accompanying drawings,
Figure 1 is a sectional elevation of a lamp having such an extinguisher and
provided with my improved means for operating the same; and,

page_text: Figure 2 is a sectional elevation of the burner portion of the lamp looking in the
direction of the arrow Figure 1.
a is the lamp reservoir, the usual central air tube affixed thereto, and c the
outer or wick tube. d, e are the extinguisher tubes which slide between the tubes b, c
and in contact with the wick, the tube e being provided with a flange fat the bottom
and connected by a hinge-plate g with the tube d.
is the extinguisher lever attached to one end of a spindle carried in a suitable
bearing upon the collar of the burner and having secured to its inner end a lever i
connected by a link to a stud k upon the tube d.
All the foregoing parts are constructed in the manner described in the
Specification before referred to and therefore need no further description.
7 is the spring which raises the extinguisher to extinguish the flame, the said
spring surrounding the central draught tube and bearing against the flange f;
and m is the releasing lever pivotted to a bracket n upon the collar of the burner
and provided at one end with a catch o adapted to engage with the extinguisher
lever. The outer end of the releasing lever m is provided with a cupp for
containing a ball or weight 2, and a spring surrounds the pivot of the said
releasing lever m and engages at one end in the bracket n and at the other end
with the releasing lever m. The normal tendency of the spring is to raise the
extinguisher to the position indicated by the dotted lines in Figure 1 and the normal
tendency of the spring is to move the catch o of the releasing lever m out of
engagement with the extinguisher lever h. So long as the ball or weight is in
the cup p, however, the disengagement of the said catch o from the extinguisher
lever is prevented, but should the lamp be upset, it is obvious that the weight
would fall out of the cup p, whereby, under the action of the spring r, the releasing
lever m would be moved to disengage the catch o from the extinguisher lever / and
the spring would thus be free to raise the extinguisher.
q
s indicates a chain which serves to prevent the ball 7 from becoming detached
from the lamp and lost.
It is to be understood that any other suitable arrangement may be employed for
releasing the extinguisher lever in case the lamp is overturned, for instance, the
ball might be carried loosely in a cup rigidly carried by the burner and having a
cap or cover attached to one end of the releasing lever m, which ball, in case the
lamp should be overturned, would, by rolling against the said cover, operate the
said releasing lever m to release the extinguisher-lever as hereinbefore described.
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. In a round wick lamp having an extinguisher composed of two concentric
tubes adapted to slide relatively with the wick-tube, a spring arranged to act upon
the said extinguisher tubes to lift the same when released, substantially as
described.
2. In a lamp provided with an extinguisher consisting of two concentric tubes
acted upon by a spring, a lever connected to the said tubes for depressing the same,
the said lever having in conjunction with it a lever-catch normally held in engage-
meut with the releasing lever by a weight but adapted when the weight is moved
to release the said extinguisher lever, substantially as, and for the purpose,
described.
3. The manufacture and use of the improved lamp hereinbefore described and
illustrated in the accompanying drawings.
