Improvements in Mechanism for Automatically Supporting the
Raised Galleries and other Adjacent Parts of Hydrocarbon and
other Oil Lamps.
I WILLIAM REUBEN LANE, Secretary to Winfield's Limited, Brassfounders, of
Cambridge Street, Birmingham, in the county of Warwick, do hereby declare the
nature of this invention to be as follows:-
This invention relates to mechanism in connection with the raising and supporting
of the gallery &c. of hydrocarbon and other oil lamps, and consists of an automatic
device, which, when the said gallery &c. is raised by hand or otherwise, falls actively
into position, and retains the said gallery &c. in its raised position.
In many of the contrivances at present in use for raising and supporting these
galleries &c., the said galleries &c. are very liable to fall unexpectedly, or others
which are more safe in this respect, are more or less complicated, but these my
improvements afford a very simple and cheap, and yet secure means of support,
automatic in its action, and such that cannot easily get out of working order.
In carrying these my improvements into effect, I proceed somewhat thus ;
gallery &c., is carried upon sliding rods, working in guides, formed in the body of
the burner, perinitting the ordinary raising and lowering motion to the said
gallery &c."
The
From the upper edge or rim of the body of the burner a portion is cut away
forming a recess for a short distance around the said rim, the remaining surface
of this recess having an inclined form with a somewhat sudden fall at the
one end.
Again. Immediately above this recess in the rim of the body of the burner, I
provide and attach to the underside of the gallery, a dependent support, which when
the said gallery is raised, falls into a vertical position, its lower end resting upon the
aforesaid surface of the recess in the rim of the body of the burner, and in that
part, where the sudden fall in such surface takes place.
This dependent leg or support is suitably shaped, that it may be readily pushed out
of the vertical line, when it is required to lower the gallery &c.
Thus when the gallery &c. is down in its normal position, the dependent support
lies flatwise in the aforesaid recess, underneath the gallery &c., nearly, if not entirely
concealed from view.
If preferred, the surface of the recessed portion of the burner may be notched or
serrated, so that the gallery &c. cannot fall unexpectedly, even although the support
may not be quite upright. Generally however this would not be necessary.

COMPLETE
Improvements' in Mechanism for Automatically Supporting the
Raised Galleries and other Adjacent Parts of Hydrocarbon and
other Oil Lamps.
I, WILLIAM REUBEN LANE, Secretary to Winfield's Limited, Brassfounders, of
Cambridge Street, Birmingham, in the county of Warwick, 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 mechanism in connection with the raising and supporting

page_text: of the gallery &c., of hydrocarbon- and other oil lamps, and consists of an automatic
device, which when the said gallery &c is raised by hand or otherwise, falls actively
into action and retains the said gallery &c. in its raised position.
In many of the contrivances at present in use for raising and supporting these
galleries &c., the said galleries &c. are very liable to fall unexpectedly, or others
which are more safe in this respect, are more or less complicated, but these my
improvements afford a very simple and cheap, and yet secure means of support,
which is automatic in its action, and such that cannot easily. get out of working
order.
In carrying these my improvements into effect, I proceed somewhat thus: The
gallery &c. is carried upon sliding rods, working in guides, formed in the body
of the burner, permitting the ordinary raising and lowering motion to the said
gallery &c.
Erom the upper edge or rim of the body of the burner, a portion is cut away
forming a recess for a short. distance around the said rim, the remaining surface
of this recess having an inclined form, with a somewhat sudden fall at the
one end.
•
Again. Immediately above this recess in the rim of the body of the burner, I
provide and attach to the underside of the gallery, a dependent support, which when
the said gallery is raised, falls into a vertical position, its lower end resting upon the
aforesaid surface of the recess in the rim of the body of the burner, and in that part
where the sudden fall in such surface takes place. This dependent leg or support is
suitably shaped, that it may be readily pushed out of the vertical line, when it is
required to lower the gallery &c.
:
Thus when the gallery &c. is down in its normal position, the dependent support
lies flatwise in the aforesaid recess, underneath the gallery &c., nearly if not entirely
concealed from view. ..:
If preferred the surface of the recessed portion of the burner may be notched or
serrated, so that the gallery &c. cannot fall unexpectedly, even although the support
may not be quite upright. Generally however, this would not be necessary.
f
Having described the nature of this my said invention, I will now proceed to more
particularly explain how it is to be performed, by reference to the accompanying
illustrative sheet of drawings, upon which are figures and letters of reference, similar
letters referring throughout the several views to the same thing or part, and in
which-
51
Fig. 1, is a front view in elevation of this my invention, with the gallery &c. in its
raised position.
Fig. is a side elevation of Fig. 1.
Fig. 3, shews the invention, as seen when the gallery &c. is lowered.
Fig. 4, is a front and side view in detail of the dependent support.
..
Fig. 5, is a modified form of the surface of the recess, upon which the lower end
of the dependent support acts.
A, is the gallery, which with its superstructure is carried upon the sliding rods b, b,
working in guides c, c, formed in the body of the burner.
This raising and lowering forms no part of this my invention, and may be effected
by any of the ordinary methods now in use.
From the upper edge of the body of the burner at d, a portion is cut away,
forming a parallel recess for a short distance around the said rim. The precise
contour or shape of the surface of this recess may be varied, but generally it would
be as shewn in Figs. 1, & 3, with an incline and a somewhat sudden fall at e.
Again, immediately above this recess in the rim of the body of the burner, I provide
and attach to the underside of the gallery, a dependent support f, hinged at its
upper end.
:
When the gallery a, &c., is raised as in Fig. 1, the support or leg, automatically
falls into a vertical position, its lower end resting upon the aforesaid surface e, of the
recess in the rim of the body of the burner, and thus retains the said gallery &c. in its
elevated position.

page_text: In some cases if desired; the surface of the recessed portion of the burner may be
notched or serrated as seen at g, in Fig. 5; generally however the before described
form is adopted.
When it is desired to lower the gallery &c. :-Upon taking hold of the gallery,
and slightly raising it, one of the fingers of the same hand is made very easily to push
the dependent leg f, forward from off the surface of the recess, when it may be
lowered by hand into its normal position as seen in Fig. 3, where it will be observed
that the dependent leg f, is practically concealed from view.
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
The combination with the gallery &c. of a dependent leg or support or its equivalent,
which shall fall and rest upon a surface prepared upon the body of the burner, to
support the said gallery in its raised position, substantially as described and illustrated
upon the drawings.
