I, ROBERT FREDERICK HALL, of "Ferndale," Church Road, Moseley, near the
City of Birmingham, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to cut-outs, fuse boxes and other electrical
fittings of a like nature, and also to couplings or connections for use in such
cut-outs and fuses for connecting the fuze wires to the pole wires and for con-
necting together lengths of wire or cable for electrical purposes generally.
In carrying out my invention as applied to a double pole cut-out, the elongated
base of the fitting is made as usual of earthenware or other non-conducting
material and is divided off longitudinally by a vertical wall or partition adapted
to insulate from one another the two fuze wires and their respective connections
with the pole wires whilst the middle of the base is crossed transversely by a
bridge, also made of insulating material, over which the fuse wires pass in pro-
ceeding from the one main wire connection to the other, and are insulated apart
both by the longitudinal middle wall and by lying within notches in the edge
of the bridge by which they are kept in their proper relative positions.
The two sets of connections, which are preferably of the special construction
hereinafter described, are respectively located on the opposite sides of the longi-
tudinal web and the short circuiting or passage of current between individual
connections of each pair (other than through their fuze wire) is prevented by
the crossing bridge. Each of the said coupling terminals or connections is
embedded within or passed through a tunnel or passage formed in a raised boss
or projection from the base, with its opposite ends extended for the lead wire and
fuse wire to be secured to by the binding screws.
The parts of this fuse or cut-out are thus so arranged that the lead wires, the con-
nections and the fuse wire lie all in a straight line with one another from end
to end of the base, which is enclosed by a suitable cover with openings or clear-
ances at the opposite ends for the wires to pass through.
The special form of connection which I propose to employ and which is also for
any electrical purpose in which one length of wire or cable is to be formed to
another, whether femporily or permanently, the same consists of a block of metal
of a cylindrical or other suitable cross section with the opposite ends respectively
split or cleft for a suitable distance inwards, but the split at the one end is
preferably formed at right angles to the other, so that the inner parts of the two
splits may intersect one another. The centres of the splits may be bored longi-

page_text: tudinally to receive the wires, onto which the separated sides are drawn together
by suitable clamping or binding screws.
A wire may be introduced into each split end either transversely or longi-
tudinally and there clamped by tightening up the binding screws.
In addition to providing an efficient means of connecting a fuse wire to a
cable, this coupling may be used for uniting together lengths of cable, for tem-
porily connecting lamp lead wires to mains, effecting temporary connections for
testing purposes and for other uses, and in every case the electrical contact
obtained is perfectly good without solder or the like being used.

Improvements in Cut-outs, Fuse Boxes, and analogous Electrical
Fittings, and in Connections for such Fittings and other Electrical
Purposes.
I, ROBERT FREDERICK HALL, of Ferndale, Church Road, Moseley, near the
City of Birmingham, 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 has reference to cut-outs, fuse boxes and other electrical
fittings of a like nature, and also to couplings or connections for use in such
cut-outs and fuses for connecting the fuze wires to the pole wires and for con-
necting together lengths of wire or cable for electrical purposes generally.
Figure to the accompanying drawings represents à longitudinal vertical
section of double pole electric cut-out constructed and provided with improved
connections between the cables and the fuze wires in accordane with my invention.
Figure 2 is a topside plan of the said cut-out, but with the cover removed.
Figure 3 is an elevation of one of the connections separately.
Figure 4 is a view of the inner or lead attachment end thereof.
Figure 5 represents a longitudinal section of the said connection upon the
dotted line a Figure 4, whilst
Figure 6 represents a plan and Figure 7 a view of the outer or cable attach-
ment end thereof.
The same letters of reference indicate corresponding parts in the said Figures 1
to 7 of the drawing.
In carrying out this form of my invention the elongated base a, of the cut-out
is made as usual of earthenware or other nonconducting material and is divided
off longitudinally by a vertical wall or partition a¹, adapted to insulate from one
another the two fuze wires b, b and the respective connections by which they
are secured to the cable wires d, whilst the middle of the base is crossed trans-
versely by a bridge a², also made of insulating material over which each of the
said fuse wires pass in proceeding from the one main wire connection to the
other, and are insulated apart both by the longitudinal middle wall and by
passing through holes a³, in the bridge by which they are kept in their proper
relative positions.
The two sets of connections, which are preferably of the special construction

page_text: hereinafter described, are respectively located on the opposite sides of the longi-
tudinal web and the short circuiting or passage of current between the individual
connections of each pair (other than through their fuze wire) is prevented by
the crossing bridge. Each of the said coupling terminals or connections is
embedded within or passed through a tunnel or passage at, formed in a raised
boss a projecting from the base, with its opposite ends extended for the lead
wire and fuse wire to be secured to by the binding screws e¹, e².
The parts of this fuse or cut-out are so arranged that the lead wires, the con-
nections and the fuse wire lie all in a straight line with one another from end
to end of the base, which is enclosed by a suitable detachable cover f with open-
ings or clearances f' at the opposite ends for the wires to pass through.
The special form of connection (represented separately in Figures 3 to 7)
which I propose to employ and which is also applicable for any electrical purpose
in which one length of wire or cable is to be joined to another as shown in
Figure 8, whether temporaly or permanently, consists of a block of metal d, of
a cylindrical or other suitable cross section with the opposite ends respectively
split or cleft at d', and d², for a suitable distance inwards, but the split d', at
the one end is preferably formed at right angles to the other , so that the inner
parts d³, d, of the two splits intersect one another. The centres of the splits may
be bored longitudinally as at to receive the wires, onto which the separated
sides are drawn together by suitable clamping or binding screws c¹, c².
A wire may be introduced into each split end either transversely or longi-
tudinally and there clamped by tightening up the binding screws.
In addition to providing an efficient means of connecting a fuse wire to a
cable, this coupling may be used for uniting together two lengths of cable, (see
Figure 8) for temporaly connection lamp lead wires to mains, effecting tem-
porary connections for testing purposes and for other uses, and in every case, a
perfectly good electrical contact is obtained without the employment of solder
or the like.
Figure 9 represents a ceiling rose constructed and provided with my improved
connection, the cover thereof being shown in section.
Figure 10 is a plan of the said fitting, with the cover removed.
Figure 11 represents a side view, Figure 12 a longitudinal section, Figure 13 a
plan and Figure 14 an end view of one of the connections employed in this
arrangement separately.
In this arrangement, the base a, which is made of insulating material is provided
with an integral projection or raised part a¹, of the shape shown in the plan,
Figure 10, and having formed in the edges thereof at a², a³, a, as, a series of
recesses into which the inner slit ends of the connections between the cable
wires and the fuze wires c, are fitted and are there secured by means of the
screws e¹, which also effect the clamping of the lead wires to the said split inner
ends of the connections which are arranged in two pairs, with the respective
fuze wires e, passing from one connection to the other and being secured to the
outer split ends d, thereof by screws e2, of each pair, whilst short circuiting
between the several connections is prevented by the intervening non-conducting
material of the raised part of the base.
The connections in this arrangement are made of a square section to fit within
the corresponding formed recesses of the base.
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
'
First: A double pole electrical cut-out or fuze box with the fuze wires, the
cable wires and their connections arranged with respect to the insulating walls
or raised parts, substantially as described and set forth in Figures 1 and 2.
Secondly: A metallic connection or wire coupling for electrical purpose, con-
sisting of a piece of metal cross split inwards from the opposite ends. with the

page_text: inner end of the one split intersecting the inner end of the other, whilst the sides
of the respective splits are drawn together by screws or equivalents thus forming
a double clamp applied in the manner and for the purposes substantially as herein
described and set forth.
