COMPLETE SPECIFICATION.
Improved Means for Extinguishing Lamps Automatically when
Upset or Tipped to a Certain Angle.
I LOUIS SCHRAMM of 1 Parkville Road, Fulham in the County of Middlesex
Electrical Engineer, do hereby declare the nature of this invention and in what
nanner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of this invention is a means whereby lamps are extinguished
automatically if upset or tipped to a certain angle.
According to this invention I connect underneath the burner a small chamber of
an inverted cone or other suitable form and in such chamber I place a heavy ball
which when the lamp is tipped to a certain angle rolls against the lower end of the
vertical rod passing through the burner the upper end of which actuates the
extinguisher of the lamp by the rising of the aforesaid rods.
And in order to explain my said invention more fully I will now proceed to
describe the same with reference to the accompanying sheet of drawings in which
Fig. 1 shews elevation partly in section of a duplex burner (with outer casing
removed) having my invention adapted thereto and as it would appear when lamp
is in use Fig. 2 shews similar view but as it would appear when the lamp is falling
over and the extinguisher closed by my invention. Fig. 3 shews detached view
hereinafter referred to. The drawing is full size.
Similar letters denote the same parts in all views.
The dome a is shewn raised in order that the extinguisher may be seen b shews
a flat tube through which the rack c passes and to the lower end of the tube b is
fixed at its lower
fixed a cone shaped chamber d, in which is placed a heavy ball e. Through
the top of the chamber d I pass a rod f, having a disc
at f, this is an
end the other end of rod f is fixed to the extinguisher
ordinary form of extinguisher and may also have the usual lever attached for
actuating it in the ordinary way. The extinguisher h and arm fare shewn
detached at Fig. 3. i shews holes in chamber d, so that the oil may pass
freely through the said chamber or the chamber may be made of wire gauze.
5 The action is as follows. When the lamp is in an upright position the ball e

page_text: would be at bottom of chamber d, as at Fig. 1, but upon the lamp falling
over or being tilted the balle would roll up the chamber d, and in so doing
would push the rod f up by coming in contact with the disc g, thereby forcing the
extinguisher up and thus extinguishing the lamp as clearly shewn at Fig. 2.
I would remark in conclusion that I do not wish to confine myself to the precise
details described and shewn.
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. In the means for extinguishing lamps automatically the loose ball e, chamber d,
rod f, in combination with the extinguisher h, all substantially as and for the
purposes described and shewn on the accompanying drawing.
2. The means for extinguishing lamps automatically when upset or tipped to a
certain angle substantially as described and represented on the accompanying
drawing.
