PROVISIONAL SPECIFICATION.
Improvements in Cord Grips of Electric Lamp Holders.
We, CHRISTOPHER THOMAS BRISCOE and EDWIN JONES, both of Central Buildings,
Richmond Terrace, Blackburn, in the County of Lancaster, Electrical Engineers,
and THOMAS SMITH JONES, of Lynwood Terrace, Blackburn aforesaid, Apprentice,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of the cord grips of
electrical lamp holders, the object being to securely fix or attach the cords or
wires to the lamp holders in such a manner that the cords or wires cannot easily
be withdrawn, nor are they liable to twist or break as heretofore.
Heretofore the cord grips have been made round or circular and have been
fitted into round or circular recesses in the lamp holder, and consequently the
grips and the cords or wires thereto were liable to turn round or twist and were
thereby subjected to a considerable amount of wear and tear.
According to this invention the cord grip is made with a round or circular upper
part so that the cap or cover may be screwed onto the holder and the lower part
of the grip is made square or angular and fits into a corresponding angular recess
in the lamp holder, the cord or wire is thus securely fixed to the lamp holder and
the cord grip and the cord therein is prevented from turning or twisting.

Improvements in Cord Grips of Electric Lamp Holders.
We, CHRISTOPHER THOMAS BRISCOE and EDWIN JONES, both of Centrai Buildings,
Richmond Terraco, Blackburn, in the County of Lancaster, Electrical Engineers,
and THOMAS SMITH JONES, of Lynwood Terrace, Blackburn aforesaid, Apprentice,
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 the manufacture of the cord grips
of electrical lamp holders and electroliers the object being to securely fix or attach
the cords or wires to the lamp holders or into their roses or fittings in such a
manner that the cords or wires cannot easily be withdrawn nor are they liable to
twist or break as heretofore.
Heretofore the cord grips have been made round or circular and have been

page_text: fitted into round or circular recesses in the lamp holder, and consequently the
grips and the cords or wires thereto were liable to turn round or twist and were
thereby subjected to a considerable amount of wear and tear.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which:-
Fig. 1 is an elevation shewing the improved part in section.
Fig. 2 is a plan view of the lamp holder with the nut for holding the cord grip
removed.
Fig. 2 is a like view of a modification of Fig. 2.
Fig. 3 is an elevation of the cord grips.
Fig. 4 is an inverted plan view of same.
According to this invention the cord grip 1 is made with a round or cylindrical
upper portion and tapered or cone shaped as shewn in Figs. 1 and 3. The lower
part 2 of the cord grip 1 is made square or augular with tapered sides as shewn
in Figs. 1, 3 and 4, or partially circular with one or more flat sides (see Fig. 2).
The square or angular part 2 fits into a corresponding angular recess 3 (see Fig. 2)
in the lamp holder so that when the cap or cover 4 is screwed onto the holder 5
the cord grips are pressed tightly into the angular recess in the holder 5 and
thereby prevented from turning round and the wire is securely held between the
grips. By using grips of this form the cord or wire is securely held therein and
prevented for turning or twisting.
The improved cord grip is equally applicable to ceiling roses, lamp holder
plugs, and electroliers generally.
Having now particularly described and ascertained the nature of our sail
invention and in what manner the same is to be performed we declare that what
we claim is:
(1) The improved cord grip herein described and substantially as illustrated by
the annexed drawings.
(2) The use in combination with an electric lamp holder of a square or angular
cord grip as and for the purpose herein described and substantially as illustrated
by the annexed drawings.
