Complete Specification Left, 14th Sept., 1898-Accepted, 5th Nov., 1898
I, JAMES BROCKIE, of No. 12, Tyson Road, Forest Hill, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved construction of canopy or carrier for an
arc lamp where it has to be fixed to the top of a lamp-post or other similar sup-
port.
My improved carrier is provided with a socket which fits over a spigot on the
lamp-post; out of this socket spring one or more arms which support a dome
shaped hood or canopy. I fix to the inside of this canopy, a cylinder, a little
larger in diameter than the lamp, and within the cylinder I suspend or support the
lamp by suitable insulators. I make the cylinder long enough to enter the open-
ing of the globe usually enclosing the arc, and I rest or support the globe upon a
cup or ring fixed to the top of the socket of the carrier.
In order to inspect or trim the lamp the globe is lifted upwards into the dome
or canopy and temporarily held by a hook or catch. The stem supporting the
globe may be hollow, having the conductors passed through it. By raising the
globe up into the dome as described, instead of lowering it as usual, the height of
the canopy above the lamp-post can be materially reduced, and the cylinder serves
to protect the lamp from the wind. Also the globe is kept central and supported
against wind pressure by means of a taper shaped ring which slides up and down
the outside of the cylinder. The taper or conical part of this ring enters the
mouth of the globe more or less deeply according as the diameter of the opening
is greater or less.

I, JAMES BROCKIE, of 12, Tyson Road, Forest Hill, in the County of Kent,
Engineer, do hereby declare the nature of this invention and in what manner the
O same is to be performed to be particularly described and ascertained in and by
the following statement:-
-
This invention relates to an improved construction of canopy or carrier for an
arc lamp where it has to be fixed to the top of a lamp post or other similar support,
as I shall describe referring to the accompanying drawings.

page_text: Fig. 1 is a sectional elevation of a lamp carrier according to my invention with
the globe in position. Fig. 2 is a corresponding view with the globe raised to
give access for trimming and cleaning. Fig. 3 is a section to an enlarged scale
of the cup for supporting the globe, Fig. 4 is a plan of the plate for the terminals,
and Fig. 5 is a plan of the cup.
My improved carrier is provided with a socket A which fits over a spigot on
the lamp-post; out of this socket spring one or more arms B which support a
dome shaped hood or canopy C. I fix to the inside of this canopy a cylinder 1)
a little larger in diameter than the lamp, and within the cylinder D I suspend
or support the lamp by suitably insulated bolt E.
I make the cylinder long enough to enter the opening of the globe G usually
enclosing the arc, and I rest, or support the globe upon a cup or ring H
fixed to the top of the socket A of the carrier.
In order to inspect or trim the lamp the globe is lifted upwards into the dome
or canopy as shewn in Fig. 2 and temporarily held by a hook or catch K. The
stem M supporting the globe may be hollow, having the leads N N passed through
it, these being preferably fixed to a plate P' to which is also fixed the conductors L
of the lamp. By raising the globe G up into the dome C as described, instead of
lowering it as usual, the height of the canopy above the lamp-post can be materially
reduced, and the cylinder I serves to protect the lamp from wind. Also the
globe G is kept central and supported against wind pressure by means of a ring R
which slides up and down the outside of the cylinder D.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A carrier for an electric arc lamp constructed substantially as described with
reference to the drawings.
