PROVISIONAL SPECIFICATION.
A Union Box for Electric Mains for Lighting, Traction, Power, or
other purposes.
I, FRANCIS DANIEL BLACK, 92, Calder Street, Crosshill, Glasgow, Electrician
and Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to a union junction box for electric mains for lighting,
traction, power or other purposes, ensuring economy of maintenance, perfect ven-
tilation and dispersion of sewage or other gases thus avoiding the possibility of
explosions; and to which access can be easily had for examination or testing
purposes.
In accordance with my invention I employ a box of square or other shape in
section extending to any desired height above the level of the ground and pro-
vided at the bottom with a space or spaces of suitable size for the inlet of air and
also at the top thereof with similar openings for the escape or exit of the air
together with any sewage or other gases which may be present.
The electric mains, when my junction box is employed, are extended upwardly,
at the one side of the box to nearly the top thereof, then across, and down at the
other side of the box and continued from thence in the usual way.
A hinged or other suitable door is provided at the side of the box for the pur-
pose of gaining access to the mains when required.

I, FRANCIS DANIEL BLACK, formerly of 92, Calder Street, Crosshill, Glasgow,
and now of 5, Prince Albert Street, Strathbungo, Glasgow, Electrician and
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 a union junction box for electric mains for lighting,
traction, power or other purposes, ensuring economy of maintenance, perfect
ventilation and dispersion of sewage, or other gases, thus avoiding the possibility

other purposes.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe same with reference to the accom-
panying, drawings in which:
Fig. 1 is a sectional elevation and
Fig. 2, a part plan, also in section, of my union box.
Referring to the said drawings I employ a box A square or other shape in
section made of any suitable material, extending to any desired height above the
level of the ground, and provided at the bottom with a space or spaces of suit-
able size for the inlet of air and also at the top thereof with similar openings a
for the escape or exit of the air together with any sewage or other gases which
may be present.
The electric mains B when my junction box (whether terminal or intermediate)
is employed, are extended upwardly or outwardly at the one side of the box to
nearly the top thereof, as shewn, then across, and down at the other side of the
box, and continued thence in the usual way, and are applicable for any overhead,
electric or other system. This arrangement can be applied to existing junction
boxes. Hinged or other suitable doors, not shewn, can be provided at the side of
the box for the purpose of gaining access to the mains when required, and for
removing water which may accumulate from drains or other sources.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The union box for electric mains for lighting, traction, power or other pur-
pose, constructed and arranged substantially in the manner as and for the pur-
poses hereinbefore described and shewn in the accompanying drawings.
2. The method of arranging the mains in the union box, substantially as herein-
before described and shewn in the accompanying drawings.
