PROVISIONAL SPECIFICATION.
Improvements in or connected with Oil Lamp Burners.
We, ALFRED HENRY GRIFFITHS, of Surrey Works, Smethwick, Managing
Director, and THOMAS BAKER SMITH, of 55 Douglas Road, Handsworth,
Manager of Lamp Department, both near the City of Birmingham, do hereby
declare the nature of this our invention to be as follows:-
This invention relates to improvements in or connected with oil, lamp burners
and refers more particularly to that part of such burners where the same is
connected to the oil container, and to the mount upon the said container.
As is well known great danger is frequently realized from the insecure connection
of these two parts by which the oil readily finds its way to the exterior of the
lamp owing to the imperfect joint.
In this our invention our object is to remove this objection as follows:-
We provide upon the lower part of the burner a male screw thread which shall
take into an internal screw thread formed in the mount, similar to some which are
now in use. The bottom collar of the burner which contains the usual cork lining,
we extend downwards in an all around deep cylindrical cap, which fits over the
exterior of the container mount and reaches down into a gutter or all around groove
formed in or upon the base of the said mount. The bottom edge of this cap may
fit tightly into the groove itself, or if desired the groove may be provided with
cork or other substance into which the cap may be forced when being screwed
home. The exterior of the cap may be ribbed or otherwise made ornamental in pattern
if desired. Thus by these means a joint is not only formed upon the underside of
the bottom of the burner and the top of the mount, but also at the exterior bottom
of the cap and the bottom of the mount, thus affording additional security against
leakage and improving very much its general appearance.

COMPLETE SPECIFICATION.
Improvements in or connected with Oil Lamp Burners.
We, ALFRED HENRY GRIFFITHS, of Surrey Works, Smethwick, Managing
Director, and THOMAS BAKER SMITH, of 55 Douglas Road, Handsworth,
Manager of Lamp Department, both near the City of Birmingham, 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 relates to improvements in or connected with oil lamp burners,
and refers more particularly to that part of such burners where the same is
connected to the oil container, and to the mount upon the said container.

page_text: As is well known great danger is frequently realized from the insecure connection
of these two parts, by which the oil readily finds its way to the exterior of the
lamp owing to the imperfect joint.
In this our invention our object is to remove this objection as follows:-
In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring in the views to the same thing or part.
Fig. 1, is a sectional view of such parts of a lamp by which our invention may
be shown.
Fig. 2, is an external view of similar parts.
Fig. 3, is an enlarged view showing a modified way of forming the cap and
⚫ securing the cork lining.
We provide upon the lower part of the burner 4 a male screw thread at 5 which
shall take into an internal screw thread 6 formed in the mount 7, similar to some
which are now in use. The bottom collar 8 of the burner, which contains the
usual cork lining 9 and which has hitherto been only of sufficient depth to carry
the said cork lining we extend downwards in an all around deep cylindrical cap 10,
which fits over the exterior of the container mount 7 and reaches down into a gutter
or all around groove 11 formed in or upon the base of the said mount 7. The
bottom edge 12 of this cap 10 may fit tightly into the groove itself, or if desired
the groove may be provided with cork or other substance into which the cap may
be forced when being screwed home. The exterior of the cap 10 may be ribbed or
-otherwise made ornamental in pattern if desired. Thus by these means a joint is
not only formed upon the underside of the bottom of the burner at 13 and the top
of the mount 7 but also at the exterior bottom 12 of the cap 10 and the bottom of
the mount 7 thus affording additional security against leakage and improving very
much its general appearance.
In Fig. 3 we have shown bow we may secure the cork lining 9 by first securing
it in the independent metal casing 8, and then insert the two in the cap 10 and
by spinning in the groove 14, the lining 9 and its casing 8 are firmly held in
position.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
In oil lamp burners the combination with such burners of the exterior cap 10
covering and fitting upon the exterior of the mount 7 all substantially as set forth
and shown and for the purposes specified.
