PROVISIONAL SPECIFICATION.
Improved Means for Raising, Sustaining, and Lowering the Galleries
of Hydrocarbon and other Oil Lamps.
HENRY BURGESS YOUNG, 24, Penton Place, Pentonville Road, London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the mechanism for raising, sustaining, and lowering the
galleries &c., of the said lamps, whereby free access is afforded to the wicks for
trimming lighting &c., and consists in attaching or fixing the gallery &c., to the
upper end of a central cylindrical spindle or stem furnished with a stud, and slideable
in a longitudinally slotted or grooved cylinder fixed to the burner. The said
gallery &c., may be raised or lowered at will by lifting or lowering it vertically
directly by hand, and may be sustained when raised to its highest limit by the
partial rotation of the spindle or stem, so that the spindle or stem stud may rest
upon a shoulder formed in the cylinder; and further provides that the said gallery
may or may not be entirely removed at the will of the operator.
Dated this 17th day of June 1890.

COMPLETE SPECIFICATION.
Improved Means for Raising, Sustaining, and Lowering the Galleries
of Hydrocarbon and other Oil Lamps.
1, HENRY BURGESS YOUNG, 24, l'enton Place, Pentonville Road, London,
Engineer, 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 the mechanism for raising, sustaining and lowering the
galleries &c. of the said lamps whereby free access is afforded to the wicks for
trimming lighting &c., and consists in attaching or fixing the gallery &c. to the
upper end of a central cylindrical spindle or stem furnished with a stud or its
equivalent, and slideable in a longitudinally slotted or grooved cylinder or guide
fixed to or formed upon the burner.
The said gallery &c. may be raised or lowered at will by lifting or lowering it
vertically, directly by hand and may be sustained when raised to its highest limit,
by the partial rotation of the spindle or stem, so that the spindle or stem stud may
rest upon a shoulder formed in or upon the cylinder or guide, and further provides
that the said gallery may or may not be entirely removed at the will of the
operator.
I will now proceed to more fully describe this my invention, with the aid of the
accompanying illustrative sheet of drawings, upon which :-
Fig. 1, is a sectional elevation of a lamp burner embracing this my invention.
showing the gallery in its lowered or normal position.
Fig. 2, is a plan view of the burner as it appears when the gallery is removed.
Fig. 3, is a sectional elevation upon line A-B (see Figs. 1 & 2), showing the
gallery raised and sustained in its raised position.
Fig. 4, is a part sectional plan view on line C-D (Fig. 1) showing the spindle or
stem suitably guided for a vertical sliding motion.
Fig. 5, is a part plan view on line E-F (Fig. 1) showing the upper side of the
wick winding chamber cover plate.
Fig. 6, is a part sectional plan view on line G-H (Fig. 3) showing the partly

being sustained.
Fig. 7, is a detached detail view of the gallery and spindle.
Figs. 8, 9.& 10, are respectively sectional plan views of the spindle on lines I-J,
K-L, & M-N, (Fig. 7).
Fig. 11, is a detail view in elevation, and also in plan of the removable stop pin
attached to the gallery spindle, as hereinafter explained.
Similar reference figures throughout the several views, refer to the same thing or
part.
In illustrating this my invention I have only shown such parts of the burner that
are necessary for the purpose in view.
1, is the body of the burner, having wick winding chamber 2, wick winding
spindles 3, 3, wick tubes 4, 4, wick winding chamber cover plate 5, and bottom
plate 6. In this plate 5, and also (in line therewith) in plate 6, is pierced a slide-
way 7, to receive the similar shaped spindle or stem 8, so that the latter is free to
slide vertically therein. 9, is the gallery carried upon the aforesaid central
spindle 8. This spindle may be varied in sectional form, but the form shown, I
find to answer very well. From the point 10, downwards to the end, it is part
circular, while the rectangular projecting part 11, (see Figs. 7, 8, 9, & 10,)
preserves it from rotation until it has been raised to a given height.
Underneath the plate 5, I provide a block piece 12, shaped as seen in section in
Figs. 4 & 6, for the purpose of increasing the surface wear of the slideway 7, and
thereby giving increased stability thereto.
At 13, I cut away a portion of the rectangular part of the spindle so that when
the gallery is raised to its full height, such gap will permit of the spindle &c. being
partly rotated, as seen in Figs. 3 & 6, the lower end 14, resting (stud wise) upon the
plate 5, and thereby sustaining the said gallery &c. in its raised position. I further
raise that part of the plate 5, nearest the hole 7, at 15, so that the part 14, has a
tendency to slide down thereon, and requiring a little effort, or positive action on
the part of the operator in order to bring back the spindle into its position for sliding
downwards again, and thus preventing any liability to the accidental falling of the
gallery.
At the lower end of the spindle 8, I provide the stop pin 16, (see Figs. 1, 3, 7
& 11) having a square neck 17, to prevent rotation or shaking, and thereby becoming
loose during the frequent part rotations of the spindle. The head 18, of this pin,
forms a stop against the plate 6, determining thereby the height to which the
gallery 9, may be raised. When desired, this said pin may be detached from the
spindle, so that the gallery &c. may be entirely removed.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In hydrocarbon and other oil lamps, the combination with the body of the
burner having slideway 7, and inclined part 15, of the raisable gallery 9, having
spindle 8, capable of a part rotation and having also a part 14, or its equivalent,
which rests upon the plate 5, when raised and thus partly rotated, constructed and
operating substantially as herein described and illustrated and for the purposes
specified.
2. The combination with the gallery 9, and spindle 8, of the removable stop
pin 16, substantially as set forth and for the purposes specified.
Dated this 11th day of March 1891.
