PROVISIONAL SPECIFICATION.
Improvements in Devices for Adapting Electric Lamps to Ordinary
Candle Fittings and the like.
I GEORGE SIDNEY SLUCE of 21 Southwold Road Upper Clapton in the County
of Middlesex Electrician do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a device by the means of which electric
lamps can be adapted to ordinary candle fittings and the like. In carrying my
invention into practice, I take a piece of tubing of brass, or any other suitable
metal or material of a convenient length, and formed with a threaded screw at both
of its ends. Upon one end is screwed an ordinary electric-lamp-holder, on the
other end is screwed a threaded milled nut which is caused to travel up and down
on the tube. Upon this latter end is slipped a cylinder of rubber or other substance
capable of being easily compressed, and of suitable length and diameter.
Underneath said cylinder and at the extreme end of said tube another nut
formed with a thread is screwed on. The device being inserted in an ordinary
candle or lamp fitting, the first mentioned nut is operated, and thereby the cylinder
is compressed, and caused to expand, and so to grip tightly the fitting to which the
device applied.
Dated this 30th day of May 1893.

Improvements in Devices for Adapting Electric Lamps to Ordinary
Candle Fittings and the like.
1 GEORGE SIDNEY SLUCE of 21 Southwold Road Upper Clapton in the County
of Middlesex Electrician 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 :—
My invention has reference to an improved device for adapting electric
incandescent lamps to ordinary candle fittings and the like. For the better
explanation of my invention I refer to the acompanying drawing in which:-
Figure 1 represents a plan view.
Figure 2 represents a longitudinal section.
Figure 3 represents my fitting in ordinary socket.
Like letters designate like parts throught the different views.
I carry my invention into operation as follows, a piece of tube A E Figure 1 of
convenient length & diameter is screwed at A and between the points HE a nut or
screwed washer B, is then screwed on the tube A E as shewn a piece of rubber C
of convenient size is then slipped on the tube A E below which and at the extreme
end E is screwed a similar washer D which may if desired be fixed permanently to
the tube A E.
In Figure II A E represents section of tube; B section of washer C section of
rubber and D section of bottom washer.
Upon reference to Figure III the action will be seen as follows:
--
The fitting as shewn in Figure I is inserted in an ordinary candle socket F G F
the nut B is then turned round on tube A E thereby travelling downwards and

page_text: consequently compressing the rubber C causing it to expand laterally thus fixing
the fitting to the candle socket F G F. The thread on the tube A E at A is for
fixing an ordinary electric lamp holder.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. In electric candle fittings the combination and arrangement of parts herein
particularly specified whereby the compression of a piece of elastic material is
made use of to fix an electric candle fitting to its socket.
II. In electric candle fittings the use of a tube in conjunction with a compressable
material to provide a method of fixture.
Dated this the Twenty-eighth day of March Eighteen hundred and ninety-four.
