PROVISIONAL SPECIFICATION.
Improvements in or connected with Lamp Gallery Raising
Mechanism.
I, THOMAS BAKER SMITH, of 55, Douglas Road, Handsworth, in the County
of Stafford, Works Manager, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in or connected with lamp gallery
raising mechanism, and consists as follows:-The_burner as a whole is made in
two parts one of which comprises broadly the body with wick tubes and wick
winding mechanism &c., and which may be termed the body part; while the
other comprises the gallery, chimney holder and cone &c., and which may be
termed the gallery:
The said gallery has formed upon it two (or more) slideways or guides through
which may pass vertical rods which are secured to the body part. Upon the body
part these rods are secured and usually occupy a diametric position, and near
to the edge so that when the gallery_is placed thereon such rods stand upwards
at the side of the chimney holder. In some cases if desired I may cut a cross
slot for a short distance down these rods so that when the gallery is placed thereon
such ends may be opened so as to prevent the removal of the said gallery. In
the body of the burner I further form bearings in which works a part rotating
spindle operated by an exterior thumb and finger piece. Upon the spindle are
formed two levers or arms which when in their turned down position lie beneath
the underside of the gallery, but by which-upon the part rotation of the spindle--
the gallery is lifted until the arms assume the vertical position, or a little more,
where they maintain the raised position of the gallery &c.
Upon the underside of these arms I further provide a hook or projection which
acts in conjunction with a projection which is formed upon the guides before-
mentioned upon the underside of the gallery. When the gallery is in its lowered
position, the projections upon the guides occupy a position between the hooklike
projection upon the arm and its spindle. Hence should the gallery be lifted
direct, that is, without the means of the spindle and arms, the projections upon
the guides will be arrested by those upon the arms and prevent removal. By
first raising with the spindle however, the projections are brought clear of each
other and the gallery may be removed for cleaning &c. purposes.
Dated this 1st day of December 1897.

Mechanism.
I, THOMAS BAKER SMITH, of 55, Douglas Road, Handsworth, in the County
of Stafford, Works Manager, 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 lamp gallery
raising mechanism, and consists as follows:
In order to more clearly explain this my invention I have appended hereunto
un illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part, and
in which:-
Fig. 1, is a part sectional side view of lamp burner made according to this
my invention with the gallery shown in the raised position.
Fig. 2, is a detailed view of the raising levers and spindle.
Fig. 3, is an end view of one of the levers.
Fig. 4, is a detailed side view, and Fig. 5, a sectional view on line A-B (of
Fig. 4) of one of the brackets which serve as vertical rod guides and lifting
stops.
Fig. 6, shows the relative position of lever and rod guide &c., when gallery is
in its lowered position.
Fig. 7, shows relative position of lever, and rod guide and stop when attempt-
ing to raise the gallery independently of the levers.
.. .!
The burner as a whole is made in two parts one of which comprises broadly the
body with wick tubes and wick winding mechanism &c., and which may be
termed the body 12, while the other comprises the gallery, chimney holder and
cone &c., and which may be termed the gallery 12ª.
:
The said gallery has formed upon it two (or more) slideways or guides' 13,
through which may pass vertical rods 14, which are secured to the body part 12.
Upon the body part 12, these rods 14, are secured, and occupy a diametric
position, and near to the edge, so that when the gallery is placed thereon; such
rods stand upwards at the side of the chimney holder 15, as shown in dotted lines
Fig. 1.
In the body of the burner I further form bearings in which works a part rotat-
ing spindle 16, operated by an exterior thumb and finger piece 17. Upon the
spindle 16, are formed two levers or arms 18, which when in their turned down
position lie beneath the underside of the gallery, but by which upon the part
rotation of the spindle-the gallery is lifted until the arms assume the vertical
position, as seen in Fig. 1, where they maintain the raised position of the
gallery &c.
い
Upon the underside of these arms I further provide a hook or projection 19,
which acts in conjunction with a projection 20, which is formed upon the
guides 13, before-mentioned upon the underside of the gallery. When the
gallery is in its lowered position, the projections 20, upon the guides occupy a
position between the hooklike projection upon the arm and its spindle, as seen
in Fig. 6. Hence should the gallery be lifted direct,-that is, without the means
of the spindle 16, and arms 18, the projections 20, upon the guides will be arrested
by the hooks 19, upon the arms and prevent removal, as seen in Fig. 7. By
first raising with the spindle however as seen in Fig. 1, the projections 19 and 20,

page_text: are brought clear of each other and the gallery may be removed for cleaning
&c. purposes.
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 a lamp burner in which the gallery part is separably carried upon the
body part and controlled by guide rods with their guides, the combination of the
raising arms 18, upon spindle 16, having hooked like ends 19, with the pro-
jections 20, carried upon the guide brackets 13, substantially as set forth and
shown and for the purposes specified.
2. The carrying of the gallery 12, upon body 12, by means of rods 14, fixed
upon the body, and the guide brackets 13, fixed upon the gallery, such rods
being external to the chimney holder 15, substantially as set forth and shown.
