PROVISIONAL SPECIFICATION.
Improvements in Lamps.
I, WALTER BRIERLEY of Penny Bank Chambers Halifax in the County of
York Patent Agent do hereby declare the nature of this invention which has been
communicated to me by Archibald Dichmont, New Post Office Works, Cape Town,
Cape Colony, Clerk of Works, to be as follows:-
This invention relates to improvements in the glass chimneys of lamps, and in
appliances connected therewith, the object being to so construct such parts that the
lamp can be lighted without removing the glass chimney as when so doing many
chimneys are broken.
According to this invention the chimney is made as ordinary but near the bottom
of said chimney, that is, about opposite to the flame, or top of the wick is formed a
small hole.
A metal clip, preferably brass, is made to clip the lower edge of the chimney,
and the outer part of the clip extends to and over the hole in the glass, so as to
cover same. In that part of the clip which covers the hole in the chimney is
formed a small door hinged to the clip and held closed by a small spring or catch.
To light the lamp the door is opened and a lighted match or taper passed through
the door, and the hole in the chimney, and so to the wick, which is lighted, after
which the match or taper is withdrawn and the door is closed.
It will be seen that the chimneys are no more expensive to manufacture, and
that the-same clip and door can be readily placed in position on any chimney.
Dated this 12th day of October 1893.

Improvements in Lamps.
I, WALTER BRIERLEY of Penny Bank Chambers, Halifax in the County of
York Patent Agent do hereby declare the nature of this invention which has
been communicated to me by Archibald Dichmont, New Post Office Works, Cape
Town, Cape Colony, Clerk of Works, 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 the glass chimneys, shades, or globes
of lamps, and in appliances connected therewith, the object being to allow of the
lamp being lighted without the necessity of removing the glass globe, shade, or
chimney from the lamp as when so doing many chimneys, globes, or shades are
broken, and the invention consists in making the shade, globe or chimney with a
hole in it, opposite, or lineable with the top of the wick in the lamp, and the hole
is covered by a door which can be opened or closed, said door being held in position
on the shade or globe by means of a spring clip.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings in
which:-
Fig. 1 is a sectional side elevation of a lamp chimney or globe with the door
attached thereto, the door being shewn open.

page_text: Fig. 2 is a front elevation of Fig. 1 the door being closed.
Fig. 3 is a sectional side elevation of another shape of lamp chimney or globe,
with the door attached thereto open.
Fig. 4 shews part of a lamp chimney or globe and hole therein.
Fig. 5 is a front elevation of the door (open) and spring clip attachment for fixing
it onto the lamp, globe or shade.
According to this invention the chimney globe, or shade 1 is made as ordinary
but near the bottom of said chimney, shade or globe that is about opposite to the
flame, or top of the wick is formed a small hole 2.
A metal clip 3 preferably brass is made so as to clip the lower edge 4 of the
chimney, globe or shade 1 and the outer part of the clip 3 extends to, and over. the
hole 2 in the glass, so as to cover same. In that part of the clip which covers
'the hole 2 in the chimney is formed a small door 5 hinged at 6 to the clip 3 and held
when closed by a. small spring or catch 7. The upper part of the clip 3 has
preferably a flange 8 formed on it which corresponds in shape with the hole 2 and
is received therein (see Figs. 1 and 3).
_ )
To light the lamp the door 5 is opened and a lighted match or taper passed
through the door, and the hole 2 in the chimney 1, and so to the wick, which is
lighted, after which the match or taper is withdrawn and the door 5 is closed:
It will be seen that the chimneys are no more expensive to manufacture; and
'that the same clip and door can be readily placed in position on any chimney, shade
or cover.
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 :--
11. The spring clip 3 at the upper end of which is the opening and door 5 in
combination with a lamp glass, shade, globe, or chimney in which is a hole such
as 2 as and for the purpose herein described and substantially as illustrated by the
annexed drawings.
