PROVISIONAL SPECIFICATION.
Improvements in Clips for Electric Conductor Casings.
We, CHARLES DARRAH of the Firm of Baxendale & Co., of Miller Street,
Manchester in the County of Lancaster, Manufacturer and Merchant, and
CHARLES CARTWRIGHT METCALFE, of Oak Bank, Dovestone Road, Ashton-on-
Mersey, in the County of Chester, Electrical Engineer, do hereby declare the
nature of this invention to be as follows: :-
This invention relates to clips employed for temporarily retaining electric wires
in their casings before or until the casing cover is properly secured, and its object
is to simplify the construction of such clips and to render them more easily
applicable and removable.
The clip constructed according to these improvements consists in its simplest
form of a strip of spring metal such as hoop steel bent to a U-form, of which the
curved part may be bent or enlarged for the insertion of a finger. The two arms
of the clip normally tend to approach each other more closely than the thickness
of the casing with which it is to be used.
The body of the casing having been fixed and the wire or wires inserted therein,
one limb of the clip is passed between the casing and the wall or ceiling to which
it may be fixed, when the other limb of the clip comes over the wire or wires and
prevents its accidental removal.
If it be desired also to provide for temporarily securing the casing cover as well
as the wires in position, a third limb may be formed or secured upon the clip about
parallel with the other two limbs, made with a tendency to close towards the
middle limb. The casing cover is then slipped between the second and third limbs
between which it is held whilst being screwed or secured in place.
If it be desired to employ the clip merely for the purpose of temporarily holding
the cover on the casing, it may be constructed of the U-form first hereinbefore
described, with a distance between the limbs corresponding with the thickness of
the casing and cover, and as before described with a tendency for the limbs to
close towards each other.

COMPLETE SPECIFICATION.
Improvements in Clips for Electric Conductor Casings.
We, CHARLES DARRAH of the Firm of Baxendale & Co. of Miller Street,
Manchester, in the County of Lancaster, Manufacturer and Merchant and
CHARLES CARTWRIGHT METCALFE, of Oak Bank, Dovestone Road, Ashton-on-
Mersey, in the County of Chester, Electrical Engineer, 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 clips employed for temporarily retaining electric wires
in their casings before or until the casing cover is properly secured, and its objects
are to simplify the construction of such clips and to render them more easily
applicable and removable.

page_text: The clip constructed according to these improvements consists in its simplest
form of a strip of spring metal such as hoop steel bent to a U form of which the
curved part may be bent or enlarged for the insertion of a finger. The two arms
of the clip normally tend to approach each other more closely than the thickness
of the casing with which it is to be used.
The body of the casing having been fixed and the wire or wires inserted therein,
one limb of the clip is passed between the casing and the wall or ceiling to which
it may be fixed, when the other limb of the clip comes over the wire or wires and
prevents its or their accidental removal. The arm of the clip which passes at the
back of the casing is preferably tapered or sharpened to facilitate its passage.
If it be desired also to provide for temporarily securing the casing cover as well
as the wires in position a third limb may be formed or secured upon the clip about
parallel with the other two limbs. The casing cover is then slipped between the
second and third limbs between which it is held whilst being screwed or secured in
place.
If it be desired to employ the clip merely for the purpose of temporarily holding
the cover on the casing it may be constructed of the U form first hereinbefore
described with the distance between the limbs corresponding with the thickness
of the casing and cover, and as before described with a tendency for the limbs to
close towards each other.
Referring to the accompanying drawings, which illustrate in what manner this
invention may be carried into effect,
Figure 1 illustrates an elevation of the simple two limbed clip holding two wires
in position in a casing; Figure 2 is a plan of the same clip, and
Figure 3 shews a three limbed clip in position holding the wires in the casing
and also supporting the cover of the casing.
As shewn in Figures 1 and 2 the clip consists essentially of two approximately
parallel arms A and B joined together by a bent or curved part C. The arms
and the curved part may have the form of a letter U but it is preferred to give
the curved part C the form shewn in the drawings so that it can more easily be
attached and removed. The casing D is held between the two arms and the
wires E F are held in place by the arm B. As before explained instead of only
placing the casing between the limbs of the clip the casing and its cover may both
be placed there and held together during the operation of screwing up. It is
preferred to taper or sharpen the front edge of the arm A so as to facilitate its
passage between the casing and the wall or ceiling.
The clip illustrated by Figure 3 is furnished with a third arm or limb B' for
holding the casing cover D¹. This third arm or limb B' may be any desired
distance from the second and may either be parallel with or approach it. As
before A and B are the first and second arms of the clip, C is the curved or beut
part to which the third arm B¹ is secured by a screw or rivet G, D is the casing
and E and F are the contained wires.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
A clip for electric conductor casings constructed substantially as and for the
purpose hereinbefore described and as illustrated by the accompanying drawings.
