PROVISIONAL SPECIFICATION.
Improvements in Lamp and Shade Holders for Incandescent Electric
Lamps.
I, JAMES BOOTH, of Cheapside Works, Birmingham, Manufacturer, do hereby
declare the nature of my said invention to be as follows:-
My invention for improvements in lamp and shade holders for incandescent
electric lamps consists in making the lamp holder in two pieces both cylindrical
in cross section (that is to say) we make the body or lower part separate from the
upper part, the upper part is raised from sheet metal by suitable tools the top of
which is screwed to receive the usual cord grip while the lower end is formed
with a flange, the lower part of the holder or body is also raised as above described
the top being bulged and is screwed externally to receive an internally screwed
ring to hold the lamp shade in position against the flange the upper and lower
parts of the holder are securely connected to each other by soldering or in any
suitable manner. In the interior of the lamp holder or body I form two projec-
tions to fit in corresponding grooves in the block of the insulator which contain
the contact plungers and their attachments and thus prevent its rotation.

COMPLETE SPECIFICATION.
Improvements in Lamp and Shade Holders for Incandescent Electric
Lamps.
I, JAMES BOOTH, of Cheapside Works, Birmingham, Manufacturer, do hereby
declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention for improvements in lamp and shade holders for incandescent
electric lamps consists in making the lamp holder in two pieces (that is to say)
I make the body or lower part separate from the upper part.
And in order that this my said invention may be more clearly understood I
will now
proceed to describe the same reference being made to the accompanying
sheet of drawings in which similar letters of reference indicate like or corre-
sponding parts throughout all the figures.
Figure 1 is a view in elevation of the upper part, of a lamp and shade holder
for incandescent electric lamps and constructed according to my invention.

page_text: Figure is a plan view of same.
Figure 3 is a view in elevation of the body or lower part of a lamp and shade
holder for incandescent electric lamps, and constructed according to my invention.
Figure 4 is a plan view of same.
Figure 5 is a view in elevation as Figures 1 and 3 connected together shewing
shade carrier ring therewith.
Figure are views respectively, plan and edge of the shade carrier ring
detached.
Figure 7 is a sectional view of Figure 5.
Figure 8 is a view in elevation of the holder in its entirety carrying the lamp
and shade supported by the cord and its grip.
a is the upper part screwed at b to receive the cord grip c while d is the flange.
e is the lower part or body bulged or swelled and screwed externally as shewn at f to
receive the internally screwed ring g. hh are the two projections which engage
in corresponding grooves in the insulating block not shewn which contain the
contact plungers and their attachments and thus prevent its rotation.
I connect the upper part a to the lower part e at the flange d which serves as
a bearing for the shade i when arranged over f and held in position by the ring g
I would observe in conclusion that I do not limit myself to the precise details
of construction or configuration of parts as shewn on the drawings as I may vary
or modify the same without departing from the principle of my said invention.
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;-
In "improvements in lamp and shade holders for incandescent electric lamps,"
1. The combination, the part a screwed at 6 for receiving the cord grip e the
flange d and projections h, h, the part e bulged and screwed at f for receiving
the carrier ring g for supporting the shade i, substantially as and for the purposes
herein before described.
.
2. The general construction combination and arrangements of parts forming
lamp and shade holders, for incandescent electric lamps substantially as herein
before described and illustrated by the drawings.
Dated 29th September 1898.
