PROVISIONAL SPECIFICATION.
Improvements in or connected with Covers for Valve Boxes and the
like.
FREDERIC GEORGE SISON HAM 13 Grosvenor Road Westminster London,
Engineer, do hereby declare the nature of this invention to be as follows.-
The object of my invention is to provide a surface cover or box for fitting over
valves or meters that can be locked up to prevent irresponsible persons tampering
with the fittings underneath.
In order to secure this object I form a secondary cover, plate, or tray, under
the nsual top or surface cover, formed with a slotted aperture or opening which
secondary cover on one side or end enters a groove or recess formed in the frame
to admit of it readily entering while the other side or end rests on a ledge or rebate
formed on the opposite side of the fiame, a lug is cast or fitted on to the frame
above below or near to the ledge or rebate in such a position that the slot formed
in the secondary cover may pass over the aforesaid lug a hole is cast or formed in
the lug to enable me to insert the semi-circular link of a padlock so that when the
padlock is fixed in position it effectually prevents the secondary cover from being
removed.
-
The secondary cover may be formed in the shape of a tray having raised edges
to retain liquids or dirt-or with tongues all round to enter into grooves formed on
frame thus making the cover practically air tight.
The secondary cover may be fitted with a small sliding or hinged door for
inspection purposes.
I may provide one or more handles on the secondary cover to readily remove it.
I may fix on the secondary cover a rim or other lock in which case I may
dispense with the lug and form a slot or hole in frame to receive bolt of lock.
The secondary cover may be hinged to the frame or screwed down by set
screws.

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
und by the following statement :-
The object of my invention is to provide a surface cover or box for fitting over
valves or meters that can be locked up to prevent irresponsible persons tampering
with the fittings underneath.
In order to attain this object I form a secondary cover, plate, or tray, under
the usual top or surface cover, having a slotted aperture at one end or side. The
Becondary cover enters a groove or recess formed in the frame to allow it to readily
נם.

pass over the aforesaid fug, a hole is cast or formed in the lug to enable me to
insert the semi circular link of a padlock so, that when the padlock is fixed in

may provide one or more handles on the secondary cover to readily remove it.
I may fix on the secondary cover a rim or other lock in which case 1 may
dispense with the lug, and form a slot in frame to receive the bolt of lock.
The secondary cover may be hinged to the frame.
The secondary cover inny be retained in position by fitting two bars across frame
to allow the cover to enter between them, in which case I may dispense with the
groove or recess formed in the frame.
I may form the secondary cover with one or more lugs, which will be arranged
to fit into conveniently placed spaces in the frame of cover.
In the accompanying diawing the top or surface cover is shown at A the frame
at B having groove or recess at C for the secondary cover G to enter and ledge or
rebate at D for the same to rest ou The lug is shown at E through a hole in
which is fixed the padlock F.
The secondary cover is marked G and the slot to pass over lug is marked H.
Ilaving 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 18-
The locking cover substantially as described and shown.
