PROVISIONAL SPECIFICATION.
Improvements in Mechanism for Raising the Galleries of
Oil Lamps.
I FRANCIS ROBERT BAKER of 242 Pershore Road, Birmingham, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in mechanism for the raising of the
galleries of oil lamps in order to afford access to the wicks for light &c., and consists
as follows:-
It may be applied to round wick burners single or duplex wick burners, but
for description sake I will describe it as applied to duplex burners.
The gallery, cone, and chimney holder is made separate from the body, in
the usual manner, and may be carried upon one or more sliding legs also in the
ordinary way, and capable of entire withdrawal when desired.
Near the outer side of the burner (and generally beneath the overhanging
ledge usually existing in the designs of present make) a vertical slotted tube is
fixed.
This slot is much in the form used in ordinary door bolts, that is, having at
each end, side recesses.
A second tube is now employed which is passed into the former, and to which
is attached a handle, knob or lift piece; such lift piece being connected thereto
through the open slot in the exterior tube.
Thus the inner tube, is as it were the sliding bolt.
This lifting piece is suitably shaped for convenience to the thumb and finger.
When the lifting piece is at the bottom of the slot the upper end of the inner
tube is level with the top of the body of the burner.
Upon the underside of the gallery, is now fixed a short leg, which passes
down into the inner tube; thus the gallery rests upon the upper end of the inner
tube.
It will be now seen that upon lifting the bolt (inner tube) the length of the
slot, the gallery will be raised to the top, the lifting piece may be turned to the
one side, into the side recess of the slot, and be thus supported in its raised position,
as long as may be required.
Also when in its lowered position, the said handle or lifting piece may be
similarly turned to the one side recess of the slot, so as to be completely out of
the way.

COMPLETE SPECIFICATION.
Improvements in Mechanism for Raising the Galleries of
Oil Lamps.
I FRANCIS ROBERT BAKER, of 242 Pershore Road, Birmingham, 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 improvements in mechanism for the raising of the

consists as follows:-It may be applied to round wick burners, or single or duplex
wick burners, but for description sake I will describe it as applied to duplex wick
burners.
The gallery, cone, and chimney holder is made separate from the body, in the
usual manner, and may be carried upon one or more sliding legs also in the ordinary
and capable of entire withdrawal when desired.
way,
To the outer side of the burner (and generally beneath the overhanging ledge
usually existing in the designs of present make) a vertical slotted tube is fixed.
This slot is much in the form used in the ordinary door bolts, that is, having at
• each end, side recesses. A second tube is now employed, which is passed into the
former, and to which is attached a handle, knob or lift piece; such lift piece being
connected thereto through the open slot in the exterior tube. Thus the inner
tube, is as it were the sliding bolt. This lifting piece is suitably shaped for
convenience to the thumb and finger. When the lifting piece is at the bottom of
the slot the upper end of the inner tube is level with the top of the body of the
burner.
Upon the underside of the gallery, is now fixed a short leg, which passes
down into the inner tube; thus the gallery rests upon the upper end of the inner
tube.
It will be now seen that upon lifting the bolt (inner tube) the length of the slot,
the gallery will be raised to the top, the lifting piece may be turned to the one
side, into the side recess of the slot, and be thus supported in its raised position, as
long as may be required.
Also when in its lowered position, the said handle or lifting piece, may be simi-
larly turned to the one side into the lower side recess of the slot, so as to be
completely out of the way.
In order to more particularly explain this my invention, and the manner in which
it may be performed, I have hereunto appended an illustrative sheet of drawings,
upon which are figures, and numbers of reference, similar numbers referring
throughout the several views to the same thing or part.
Fig. 1, is a general view of a lamp burner to which this invention is applied,
and more particularly showing a front view of the bolt device.
Fig. 2, is a side view of the arrangement showing the gallery in its lowered
position.
Fig. 3, is a part sectional similar side view of the arrangement, but showing the
gallery in its raised position.
1, is the body of the burner. 2, is the gallery, which together with what is
thereon, is carried upon the legs 3, 3. To the body of the burner, is now
attached the tube 4, down the front of which is made the slot 5, having top
and bottom side turns or recesses 6 and 7. Within this tube 4, is a second
tube 8, see Fig. 3, to which is fixed the lifting stud 9, having the thumb and
finger lifting piece 10. This stud 9, travels in the slots 5, 6 & 7, that is, the
tube 8, is free to move vertically and horizontally. When in its lowered
position as seen in Figs. 1 and 2, the top of this tube is level with the top of
the tube 4, so that the gallery 2, rests thereon. To the underside of the
gallery is secured the short leg 11 which enters into the inner tube 8.
It will now be readily seen that by raising the piece 10, the gallery &c. is raised;
when by turning the said piece to. the one side the stud 9, enters the side recess 6,
and thus the gallery &c. is retained in its raised position. Similarly by turning
the piece 10 to the one side when at the bottom of the slot into the recess 7, the
gallery is prevented from being raised.
As before intimated, instead of the legs 3, 3, one may be used, in which case a
rectangular section would as usual be generally employed. Also as usual the
'collars 12, 12, may or may not be used.

page_text: Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Raising the galleries of lamps, from the bodies of their burners, by the combi-
nation of the bolt (tube) 8, stud 9, and lift piece 10, with the tube 4, having slots 5,
6 & 7, after the manner described and shown upon the drawings.
