An Improved Electricity Meter Shelf Fixing or Box, and Main
Connection Board or Box Combined.
1, FREDERICK WILLIAM EDMUND JONES, of 24, Claremont Road, Leamington,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
A shelf or fixing board of wood metal or any other suitable material on or to
which any ordinary meter for the registration of the passage or consumption of
electricity may be "mounted or affixed combined with a board of suitable material
and construction to which may be affixed the various switches apparatus or fittings
for the control registration or distribution of the electric current, the whole being
so enclosed as to admit of one seal protecting the whole or either portion as may
be determined but in any case to allow if desired free access to the operating handle
of the main switch or switches whilst preventing access
to any other
part of the apparatus protected by the seal as aforesaid without break-
ing the said seal. At the same
various
time the inspection of the
dials or other parts of the apparatus without breaking the seal is provided for by
the insertion of a window or windows in the front or other part of the enclosing
case and for the ready fixing or manipulation of the whole or any portion of the
apparatus by hinging the front of the case to form a door or doors which may be
secured if desired by any suitable fastening or lock in addition to the seal.

An Improved Electricity Meter Shelf Fixing or Box, and Main
Connection Board or Box Combined.
I. FREDERICK WILLIAM EDMUND JONES, of 24, Claremont Road, Leamington,
in the County of Warwick, Electrical Engineer, do hereby declare the nature of
my said invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
My invention has for its object an improved electricity meter shelf fixing or box
and main connection board or box combined by which I am enabled to assemble
all the junctions of the supply mains to the house leads in a compact and con-
venient form and effectually safeguard them by a single seal thus preventing them
being tampered with without first breaking the seal.
In order that my invention may be more clearly understood and easily carried

page_text: into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated an example of my meter shelf fixing or box.
Figure 1 is a front elevation of my meter shelf fixing or box.
Figure 2 is a similar view to Figure 1 with the door removed.
Figure 3 is a side elevation of Figure 1...
In carrying my invention into practice I form the box or casing A preferably
of cast iron with the single door at which covers the entire front or separate doors
may be provided for the upper and lower parts. This door is preferably hung on
hinges cast in the interior of the casing so as to enable it to be easily lifted off
if required when open and is provided with the windows a and a³ so as to enable
the dials of the meter B to be easily read and the condition of the main fuses b
being seen without breaking or disturbing the seal $ which is fixed by the
authorities so as to prevent the various parts from being tampered or interfered
with. This seal is attached to the cords or its equivalent which passes through
the holes formed in the door and through the holes formed in the side of the case
or box thus preventing the door from being opened without first breaking the seal.
When two doors are provided the cord or its equivalent would be passed through
holes formed in each door and through a hole formed in the side of the box or case
the end being then sealed in a similar manner as shewn. The door is also pro-
vided with the lock a³ as an extra security. The top portion or wall a³ of the case
or box is formed with the grooves on its edges which slide onto the projections a
formed at the top of the sides of the box or case so as to enable the top portion a
to be withdrawn when the door is open for the purpose of removing the cover of
the meter without taking the meter out of the box or case, thus the meter may at
anytime be calibrated with convenience without being disturbed. The shelf or
partition D on which the meter B is fixed is preferably made of wood as shewn
resting upon the lugs or brackets d' formed on or fixed to the inner sides of the
box or case.
The demand indicator E is fixed to the back of the box or case and
the other main fittings which may be of any suitable standard designs are mounted
on insulating bases. The slot is formed in the side of the box or case so as to
allow the main switch handle H to be operated from the exterior as clearly shewn
at Figures 2 and 3. The lugs or bosses are formed at the back of the case for
the screws a or the like to pass through for fixing the box or case in position. If
desired for convenience in handling the box or case may be provided with a handle
or handles and four feet may be cast on or attached to the base.
By the employment of a box or case as described a great saving of time and
trouble is effected in fixing the various parts as they are all concentrated under one
cover.
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:
CLAIMS.
First The improved electricity meter shelf fixing or box and main connection
board or box combined consisting essentially of the box or case such as A with
its door a¹ or doors having windows or openings such as a² and a³ and the shelf
or partition D and sealed by a seal such as S or its equivalent in the manner and
for the purpose substantially as herein set forth and as shewn upon the accompany-
ing sheet of drawings.
Second: Assembling and enclosing an electricity meter or meters, demand
indicator or indicators, switch or switches and fuse or fuses together in a box
or case such as A and sealing the same in the manner and for the purpose sub-
stantially as herein set forth and as shewn.
Third Assembling and enclosing an electricity meter or meters and demand
indicator or indicators in a box or covers such as A and sealing the same in the
manner and for the purpose substantially as herein set forth and as shewn upon the
drawings.

page_text: Fourth Assembling and enclosing an electricity meter or meters together with
a switch or switches and fuse or fuses in a box or case such as A and sealing the
same in the manner and for the purpose substantially as herein set forth and as
shewn upon the drawings.
