PROVISIONAL SPECIFICATION.
Certain Improvements in Pendent Oil Lamps or Lanterns.
J, ALBERT EDWARD MITTON, of 6, George Street Parade, in the City of
Birmingham, Lamp Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to those pendent oil lamps or lanterns in which the
lamp ring carrying the oil vessel is so supported or carried that it can be drawn
down below the bottom of the lanteru (for the removal of the oil vessel and other
parts of the lamp proper) or moved up into the bottom of the lantern and there
fixed to support the lamp proper in position in the lantern. This invention consists
in arranging the lamp ring and its supports or guides as hereindescribed whereby
the construction of the same is simplified and the lamp ring and lamp supported
thereby are rendered perfectly secure as the lamp ring cannot be accidently
detached and drop down from the lantern as is the case in some of those pendent
oil lamps in which the lamp ring is held in the lanteru by a catch.
According to one method of carrying out my invention the lamp ring is provided
with and fixed to upright tubular or other slides which are free to move up and
down in guides arranged by preference in say two opposite corners of the lantern
1 find that two of these slides are sufficient and I prefer to make them from one
piece of tube which is bent centrally into a loop or ring at the top of the lantern
and the two parts of the tube continued downwardly in two corners of the lantern
and their bottom ends fixed to the lamp ring. To the underside of the lamp ring
there is fixed a metal loop or other means for holding by the hand when moving
the lanp ring up or down. The said guides terminate at the top in a central loop
or hook which engages with another hook or the like formed at the centre of the
how or upper frame of the lantern and thus the lamp ring and lamp supported
thereby are held in position in the lantern.
When it is desired to lower the lamp ring and lamp from the lantern the loop or
other attachment below the ring is gripped by the hand and pushed upwardly
slightly so as to unhook the upper part of the guides from the hook or the like on
the bow or upper frame of the lantern when the lamp ring and its guides will be
free to be drawn down as required, suitable stops on the slides preventing them
from being drawn down too far.
When the lamp ring and its guides with the lamp proper are pushed up into
position in the lantern, the ring loop or the like on the top of the guides engages
with the hook or the like on the bow or upper frame of the lantern and thus the
lamp with the ring and guides are held in place in the lantern.
Instead of the top of the guides being made to engage with a central hook or
ring on the bow or upper part of the lantern frame as above described the said
guides may be similarly constructed to hook on to any other part of the lantern.

Certain Improvements in Pendent Oil Lamps or Lanterns.
I, ALBERT EDWARD MITTON, of 6, George Street Parade, in the City of
Birmingham, 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 :-
This invention has reference to those pendent oil lamps or lanterns in which the
lamp ring carrying the oil vessel is so supported or carried that it can be drawn
down below the bottom of the lantern (for the removal of the oil vessel and other
parts of the lamp proper) or moved up into the bottom of the lantern and there
fixed to support the lamp proper in position in the lantern.
This invention consists in arranging the lamp ring and its supports or guides as
hereindescribed whereby the construction of the same is simplified and the lamp
ring and lamp supported thereby are rendered perfectly secure as the lamp ring
cannot be accidently detached and drop down from the lantern as is the case
in some of those pendent oil lamps in which the lamp ring is held in the lantern by
a catch.
I will describe this invention by referring to the accompanying drawing on
which
Figs. 1 and 2 are cross sectional elevations of a pendent oil lamp or lantern
constructed according to this invention, Fig. 1 shewing the movable lamp ring and
its supports or slides in the positions which they occupy when they are pushed up
into the lantern and Fig. 2 shewing the said lamp ring and its slides when drawn
down below the bottom of the lantern for the removal of the oil vessel and lamp
proper;
Fig. 3 is a separate view of the lamp ring and its supports or slides.
The same letters of reference indicate the same parts in all the figures of the
drawing.
A is the lantern B is the usual bow or upper frame of the same by which the
lantern A is supported in the usual manner from the central rod or tube C.
In carrying out my invention the lamp ring D, in which is placed the oil vessel
of the lamp proper, is provided with and fixed to two upright tubular or other
slides E E which are free to move up and down in guides f f f f arranged by
preference in two opposite corners of the lantern A. I find that the two
slides E E are sufficient although I do not confine myself to this particular
number as three or more slides may be similarly used. I prefer to make the
slides E1 E from one piece of tube which, as shewn on my drawing, is bent
centrally into a loop or ring E3 at the top of the lantern and the two parts E' E'
of the tube are continued downwardly in two corners of the lantern and their
bottom ends fixed to the lamp ring D. To the underside of the lamp ring D there
is fixed a metal loop such as F or other suitable means for holding by the hand
when moving the lamp ring up or down. The loop E³ of the slides engages with a
hook G or the like formed at the centre of the bow or upper frame B of the
lantern as shewn in Fig. 1 and thus the lamp ring D and lamp supported thereby
are held in position in the lantern.
When it is desired to lower the lamp ring D and lamp from the lantern A, the
loop F or other attachment below the ring D is gripped by the hand and pushed
upwardly slightly so as to unhook the upper part E' of the slides from the hook G
or the like of the bow or upper frame B of the lantern. The lamp ring D and its
slides E E will now be free to be drawn down as required and when thus drawn
down the stops h on the slides E' E' will come in contact with the guides fif" as
shewn in Fig. 2 and thus prevent the lamp ring D with its slides E' E' from being
drawn down too far.

page_text: When the lamp ring D and its slides E' E' (with or without the lamp proper
carried thereby) are pushed up into position in the lantern as shewn in Fig. 1, the
ring loop or the like E on the top of the slides engages with the hook & or the
like on the bow or upper frame B of the lantern and thus the ring and its slides
are held in place in the lantern.
It will be evident that instead of the slides E1 E' being made with a loop E'
they may similarly be made with a hook at the top to engage with the hook or
loop G on the bow or upper frame of the lantern.
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 :-
In a pendent oil lamp or lantern of the kind herein referred to, the combination
of a lamp ring and upright slides fixed thereto adapted to move vertically in guides
in the corners of the lantern so that the lamp ring may either be drawn down
below the lantern or pushed up into the same, said slides terminating in a hook or
loop at the top adapted to engage with a corresponding hook or loop on the bow
or upper frame of the lantern and thus support the lamp ring and its slides in the
lantern and allow of their being unhooked and moved down below the lantern, all
substantially as described.
