PROVISIONAL SPECIFICATION.
Improvements in Oil Lamp Burners.
We ALFRED HENRY GRIFFITHS, and EVERED AND COMPANY LIMITED,
both of Surrey Works, Smethwick, near the City of Birmingham, Manufacturers
do hereby declare the nature of this invention to be as follows:-
This invention has relation to the construction and arrangement of the inner
parts of the burner and more particularly to what is known as the loose perforated
bottom employed in such lamps.
As ordinarily made, this perforated bottom is made to slide loosely upon the wick
tubes, and otherwise cut away or slotted &c. to accommodate other parts that may
be necessary. This bottom is then slid on to the said wick tubes before the sliding
extinguishing shutters are passed on. When the latter are placed in position
therefore, the said perforated bottom is capable only of a very limited amount of
being lifted, in order to clean &c. thereunder. In our invention however we over-
come this difficulty as follows:-The said perforated bottom is made in two or more
parts, and such parts connected together by link hinges, so that when it is desired
to clean thereunder the whole may be readily opened upon such hinges or links and
entirely removed by which means complete access is afforded to the whole of the
inner parts of the body of the burner.
"
A take hold or handle piece is provided upon the upper side of the perforated
bottom by which it may be removed easily and conveniently. Such ready access
to these parts will the better ensure cleanliness and thereby secure much greater
safety than heretofore.

COMPLETE SPECIFICATION.
Improvements in Oil Lamp Burners.
We ALFRED HENRY GRIFFITHS, and EVERED AND COMPANY LIMITED,
both of Surrey Works, Smethwick, near the City of Birmingham Manufacturers
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 relation to the construction and arrangement of the inner
part of the burner known as the loose perforated bottom employed in such lamps.
As ordinarily made, this perforated bottom is made to slide loosely upon the
wick tubes, and otherwise cut away or slotted &c., to accommodate other parts as
may be necessary. This bottom is then slid on to the said wick tubes before the
sliding extinguishing shutters are passed on. When the latter are placed in position
therefore, the said perforated bottom is capable only of a very limited amount of
being lifted, in order to clean &c. thereunder. In our invention however we over-
come this difficulty as follows:-The said perforated bottom is made in two or more
parts, and such parts connected together by link hinges, so that when it is desired
to clean thereunder, the whole may be readily opened upon such hinges or links,
and entirely removed; by which means complete access is afforded to the whole of
the inner parts of the body of the burner.
"
A "take hold or handle piece is provided upon the upper side of the perforated.
bottom by which it may be removed easily and conveniently. Such ready access.

page_text: to these parts will the better ensure cleanliness and thereby secure much greater
safety in the use of the lamps than heretofore.
In order to more particularly describe this our invention, and how it may be
performed, we have hereunto appended an illustrative sheet of drawings, upon
which are figures and numbers of reference, similar numbers referring throughout
the several parts to the same thing.
Fig. 1, is a plan of a burner having its gallery removed showing the perforated
bottom in position.
Fig. 2, is a detailed plan view of the perforated bottom removed from the
burner.
Fig. 3, is a skeleton detailed view of the perforated bottom showing the hinge
action.
As shown the perforated bottom is made in two parts 1 and 2, and such parts are
connected together by the link hinge 3, with joints 4 & 5. 6, is a "take hold" or
handle by which it may be removed or replaced easily.
The slots or openings 7, 8 & 9, or others of a similar kind are made to permit of
the wick tubes 10 & 11, arms or levers 12 & 13 &c.
As before intimated, although in the case illustrated we have only shown one of
such hinges with the bottom in two parts, still in some cases we may make it in
more parts with the necessary number of hinges.
Having now particularly described and ascertained the nature of this our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Making the perforated bottoms of lamp burners, in two or more parts, and
hinged together after the manner herein described and illustrated, and for the
purposes specified.
