PROVISIONAL SPECIFICATION.
An Improvement in Connections for Electrical Fuses.
THOMAS MCEWAN, Electrical Engineer, 36, Dick Place, Grange, Edinburgh, do
hereby declare the nature of this invention to be as follows:-
-
This improvement consists of an arrangement whereby electrical fuse wires are
instantaneously connected and firmly gripped, making a perfectly efficient elec-
trical and mechanical connection in the following manner.
When they are applied to a fuse board instead of the usual fuse studs, screws,
and washers to bind the wires, there is employed a circular piece of brass working
between jaws.
An eccentric motion is imparted to this and by the use of a small handle or lever
actuating the eccentric, the bottom part of the eccentric is brought tightly into
contact with the inside lower part of the jaws and by the fuse wires being placed
between the two,, they are firmly held.
Dated this 10th day of September 1898.
An Improvement in Connections for Electrical Fuses,
I, THOMAS MCEWAN, Electrical Engineer, of Hazelwood," 36, Dick Place,
Grange, Edinburgh, 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 an improvement in connections for electrical fuses and
consists of an arrangement whereby electrical fuse wires are instantaneously con-
nected and firmly gripped, making a perfectly efficient electrical connection.
When applying my invention to a fuse board I proceed as shewn in the accom-
panying drawings in which Fig. 1 is an elevation and
Fig. 2 a plan of a portion of such a board shewing my improvements applied
thereto.
Referring to the said drawing I dispense with the usual fuse studs, screws
and washers for binding the wires and in lieu thereof I employ a circular disc A
of brass or other suitable metal working between jaws B, the said discs being
pivoted at b so that an eccentric motion can be imparted thereto. To effect the
connection, the fuse wires are placed between the jaws B and the eccentric discs A
brought tightly onto the top of the wire by means of small handles or levers C.
Although I have described and illustrated the eccentric connection as applied
ED 071

page_text: to an ordinary fuse board I desire it to be understood that the same or similar
arrangement may be employed for carrying the fuses used with switches or for
carrying fuses of any kind wherever used.
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 means whereby fuse wires are instantaneously and firmly gripped to make
an electrical connection, consisting of the disc A mounted eccentrically between
the jaws B of the terminal between which and the under side of the said disc the
fuse wires are placed, the said parts being arranged and operating substantially in
the manner as herein before described and shewn in the accompanying drawings.
Dated this 5th day of May 1899.
