I JOSEPH ALEXANDER JECKEI L of South Shields in the Count
Electrical Engineer to the Borough of South Shields do hereby declare the nature
of this invention to be as follows
-
My invention has for its objects, first to effect improvements in the construction
of disconnection fuse boxes, so as to enable the fuse to be used both as a fuse and
as a disconnection plug or switch so that only one piece of apparatus is used in
place of two zone disconnection fuse box is used in place of a fuse box and
disconnection plugs or switch
Secondly to reduce all liability to short circuit the positive and negative cables
to a minimum
To effect these objects I attach to the end of each cable a suitable metallic
socket
These metallic sockets are completely imbedded in recesses formed in a base
made of porcelain or other suitable non conducting material so that the insulating
covering of each cable enters the rece s in such a manner that there is no bare
conductor exposed
Each of these sochets is placed in metallic contact with two metallic clips
between which the fuse carrier is inserted
The fuse carrier I make of vulcanite fibre or other non-conducting material to
each end of which is attached a metallic shoe piece which fits into the metallic
clips in connection with the socket on each cable
The fuse wire bridges from one of these metallic shoes to the other, being firmly
attached to each in such a manner as not to be liable to abrasion when the shoes
ale inserted in the clips
The vulcanite fibre fuse carrier is so formed as to form a convenient handle by
means of which it can be readily withdrawn from the clips, and the circuit thereby
broken, thus forming at the same time a safety fuse and a disconnection plug
In
My invention is applicable to either single pole fuses or double pole fuses
the double pole fuses a budge or partition of non-conducting material is inserted
between the two fuses, the whole being enclosed by a suitable cover

Improvements in and relating to Electric Cut Outs
I, JOSEPH ALEXANDER JECKELL, Borough Electr cal Engineer's Office,
South Shields, in the County of Durham, Electrical Engineer, do hereby declare
the nature of 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 has for its objects
-
-
Firstly-To effect improvements in the construction of disconnection "fuse
"

"fuse and as a
disconnection-plug,' or "switch" so that only one piece of apparatus is used in
place of two, viz one disconnection "fuse" box is used in place of a ⚫ fuse" box
and a "disconnection plug' or "switch
Secondly-To reduce all liability to "short-circuit the positive and negative
cables to a minimum
To effect these objects I attach to the end of each cable a suitable metallic
socket These metallic sockets are completely imbedded in recesses formed in a
box made of porcelain, or other suitable non-conducting material, so that the
insulating covering of each cable enters the recess in such a manner that there is
no bare conductor exposed

,
Each of these sockets is placed in metallic contact with two metallic clips
between which the "fu e-cariier Is inserted The "fuse carrie I make of
vulcanite fibre, or other non-conducting material, to each end of which is attached
a metallic shoe piece which fits into the metallic "clips" in connection with the
socket of each cable
"
The "fuse ne bridges from one of these metallic shoes to the other, being
firmly attached to each in such a manner as not to be liable to abrasion when the
two shoes are inserted in the "clips

The vulcanite fibie " carrier 1 so shaped as to form a convenient handle by
meins of which it can be readily withdrawn from the " clips and the circuit
thereby broken, thus forming, at the same time, a safety-fuse and a
"disconnecting-plug'
My invention is applicable to either "single-pole fuses" or to " double-pole
fuses In the case of "double-pole fuses a bridge or partition of non-conducting
material is inserted between the two "fuses' the whole being enclosed by a
"
stable cover
"

page_text: 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
-
The improvements consisting in the combination of a fuse "cutout' and a
disconnecting-plug (or switch) in one, in such manner that the fuse wire
mounted in a carrier acts as a safety fuse and current connecting plug when
inserted, and as a current disconnecting plug when withdrawn, thus operating
as two separate instruments in one apparatus combined with a provision in
double-pole fuses for preventing "short circuiting," by accident or negligence,
the whole arranged, constructed, and operating substantially as described and
shewn on the drawings herewith
