PROVISIONAL SPECIFICATION.
Improvements in Electrical-current-distributing Fuze and Switch
Boards.
1, ALFRED WATSON, of 180, Hockley Street, in the City of Birmingham, Elec-
trical Accessories Manufacturer, do hereby declare the nature of this invention
to be as follows:
-
This invention relates to current-distributing fuze and switch boards, consisting
primarily of a series of replacement fuzes, with their carriers interlocated between
sub-current terminals and an omnibus bar in connection with the main current
terminal.
The object of my invention is to effect a ready and efficient connection between
the sub-current terminals and the "bus" bar in multiple way fuze boards or in
distributing switch boards.
Thus, the fuzes used in distributing an electric current from an omnibus bar,
which I make of a circular section and either from a solid metallic bar, or from a
tube of good conducting metal, are arranged in series, with their one ends
attachedly connected to and seating themselves upon, the said omnibus bar, which
is itself in connection with, or is fitted into, a main terminal, which may, in the
latter case, be made to itself act as a terminal, whilst their other ends are made
in the form of embracing clips, which slip over and are affixed upon, the sub-
current terminals, or abut against the same, clipping it by a spring clip.
The attachable or replacement fuze carriers are made of earthenware, fibre or
other good insulator, with the bus-bar end provided with a metallic shoe having
a semi-seating of the same inside curvature as the outside diameter of the said bus
bar, whilst the other end has a like shoe carrying a bifurcated and yielding clip
adapted to fit over and engage with the sub-current terminal. The fuze runs
between the said shoes, and is connected at its ends thereto by a screw or other
metallic connection.
The base or board is made of slate, china or other insulator upon which the
several distributing fittings are mounted.

page_text: 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 current-distributing fuze and switch boards consisting
primarily of a series of replacement fuzes with their carriers interlocated between
sub-current terminals and an 66 omnibus" bar in connection with the main current
terminal.
The object of my invention is to effect a ready and efficient connection between
the sub-current terminals and the bus" bar in a multiple way fuze board or in
distributing switch boards.
Thus, according to my improvements, the fuzes used in distributing an electrical
current from an omnibus bar, which I make of a circular or other suitable section
and either from a solid metallic bar or from a tube of good conducting metal, are
arranged in series, with their one ends attachedly connected to and seating them-
selves upon, the said omnibus bar, which is itself in connection with, or is fitted
into, a main terminal, which may, in the latter case, be made to itself act as a
terminal, whilst their other ends are made in the form of embracing clips or suit-
able contacts which slip over and are affixed upon, or abut against the sub-current
terminals.
Figure 1 of the accompanying drawing represents a topside plan of an electrical
current-distributing fuze board constructed and arranged according to one form
of my invention.
Figure 2 is a plan of the said fuze board, with the replacement fuze carriers
removed, and showing only the main current omnibus bar and the sub-current
terminals.
Figure 3 represents a cross section of Figure 1 upon the dotted line a, showing
more clearly the connections of the end contacts of the removable fuze bars or
carriers respectively with the omnibus bar and one of the sub-current terminals.
Figure 4 is a like section as Figure 3, but showing one of the detachable or
replacement fuze carrier bars in the act of being removed.
Figure 5 is a side elevation of one of the replacement fuze carriers separately,
and Figure 6 is an elevation of the bus-bar contact end of the same.
Figure 7 is a topside plan of the said carrier and Figure 8 an underside plan
thereof.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is the base of the distributing fuze board, b the omnibus bar, arranged along
one side of the base, and having a main current terminal at b¹, whilst c are a
series of sub-current terminals arranged on the opposite side and having binding
screws c¹, by which the sub-current lead wires are connected therewith. d are
the fuze wires, carried upon one side of the detachable or replacement fuze car-
riers e, each of which is made of earthenware, fibre or other good insulator, with
the bus-bar end e', provided with a metallic shoe f, having a semi-seating f¹, of
the same inside curvature as the outside diameter of the said bus-bar, whilst the
other end e³, has a like shoe g, carrying a bifurcated and yielding clip 9', adapted
to fit over and engage with one of the sub-current terminals. The wire fuze d,
runs between the said shoes and is connected at its ends thereto by screws e³, or
other metallic connection.
The base or 'board" a, is made of slate, china or other insulator upon which
the several distributing fittings are mounted.
The application of my invention to switch boards having removable fuze wire
carriers differs in no essential respect from its application to current distributing
boards as herein described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
-
First: In electric current distributing fuze and switch boards, making con-

page_text: nection between the main current conductor or "omnibus" bar and the sub-cur-
rent terminals by means of metallic contacts carried by detachable or replacement
non-conducting fuze bars, and connected together by the fuze wires.
Secondly: In electric current distributing fuze and switch boards, providing
the opposite ends of the replacement or detachable non-conducting fuze bars
respectively with a metallic clip or equivalent contact embracing or abutting
against one of the sub-current terminals, and metallic open sided shoe or like
contact resting against the main current conductor or omnibus bar, said clip and
shoe contacts being in electrical connection with one another by a fuze wire
stretched between them, substantially as described and set forth.
Thirdly: In electric current distributing fuze and switch boards, the combina-
tion with a base of insulating material, provided with a main current omnibus
bar and a series of sub-current terminals, of a corresponding series of replacement
fuze-wire carrier-bars, also made of insulating material and having main and sub-
current terminal contacts at the ends, substantially as described and set forth.
Dated this 11th day of March 1898.
