COMPLETE SPECIFICATION.
Appliance for Open-flame Oil Lamps for Protecting the Flame
thereof.
I, PEDRO BASCARAN, of San Sebastian, Spain, Military Officer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
My invention relates to the class of open flame oil lamps largely used by the
lower classes on account of their cheapness and which consist simply of a closed
flat bottomed oil reservoir with a tubular extension at top through which
passes an ordinary wick that is raised and lowered by a toothed disc with
button.
Such lamps, in addition to being very cheap, also have the advantage that
they burn oil such as petroleum very economically, but they have the disadvantage
that owing to the flame being quite unprotected, it is very easily extinguished, even
when the lamp is only slightly moved about, and as such lamps are of a necessity
being constantly carried from one place to another, they require to be continually
relighted, causing great inconvenience.
The object of my present invention is to provide an inexpensive means for
obviating the above described disadvantage, while at the same time the brilliancy
of the flame is increased.
For this purpose I provide a small lamp gallery adapted for holding a short
lamp glass and having centrally a split tube of such size as to fit easily with spring
action upon the wick tube of the above described lamp. The gallery is formed
with a solid bottom having small apertures for the entrance of the requisite air
supply for the flame, which being thus enclosed by the gallery and glass, is
effectually protected against being extinguished by draught or by being moved
about, while at the same time the column of heated air within the chimney glass
will produce an increased air supply to the flame and thus insure a smokeless
combustion and greater brilliancy.
On the accompanying drawing
Fig. 1 shews an ordinary lamp of the above described kind..
Fig. 2 shews an elevation and plan of the gallery.
Fig. 3 shews an elevation and plan of the chimney glass and
Fig. 4 shews the before mentioned lamp with the gallery and glass attached.
The gallery A is formed of a metal disc the figured edge a of which is turned up
as shewn to receive the chimney glass B; it has any desired number of small
holes a¹ formed in it for allowing access of a sufficient air supply to the flame, while
preventing the latter from being disturbed by draughts. To the central hole of
the disc is fixed the split tube a² which is somewhat shorter than the wick tube
and is by preference made slightly tapering, so that while at its lower end it will
fit easily over the wick tube of the lamp, the upper end, on being slid over the wick
tube as at Fig. 4 will grasp this sufficiently tight to insure the gallery being held
on firmly.
The glass B is made to fit tightly into the figured rim a of the gallery, and it is
by preference made nearly twice the height of the wick tube, so as to afford a
sufficient draught without being inconveniently high.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
An appliance for protecting the flame of open flame oil lamps consisting of

and carrying a chimney glass, substantially as described with reference to the
drawings.
