of this invention to be as follows:-
The object of my invention is to prevent the interference by unauthorized persons
with the opening or closing of stop cocks and valves used in systems of public and
other water supply. For this purpose I provide two clips having at their lower ends
projections which pass under a flange or other projecting part of the cock or valve
and having at their upper ends projections or lugs which adjoin or unite above the
spindle or upper part of the cock or valve such upper projections or lugs being
adapted to receive a padlock or other locking appliance the key of which is kept by
some person in official charge of the cock or valves. Over the clip and upper part
of the cock is passed a box or housing which has a hole for the said lugs to pass
through and be locked as described above or beyond such housing. Or the
aforesaid clips may have lower projections which take under the pipe but without
necessarily disturbing the ground.

COMPLETE SPECIFICATION.
Locking Appliance for Stop Cocks and Valves.
1, JOSEPH HALL of the Municipal Offices, Cheltenham, in the County of
Gloucester, Borough Surveyor and Water 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 :-
The object of my invention is to prevent the interference by unauthorized
persons with the opening or closing of stop cocks and valves used in systems of
public and other water supply. For this purpose I provide two clips having at
their lower ends projections which pass under a flange or other projecting part of the
cock or valve and having at their upper ends projections or lugs which adjoin or
unite above the spindle or upper part of the cock or valve such upper projections or
lugs being adapted to receive a padlock or other locking appliance the key of which
is kept by some person in official charge of the cock or valves. Over the clip and
upper part of the cock is passed a box or housing which has a hole for the said lugs
to pass through and be locked as described above or beyond such housing. Or the
aforesaid clips may have lower projections which take under the pipe but without
necessarily disturbing the ground.
In the accompanying drawings I have illustrated a locking appliance constructed
according to this invention and adapted as an example to a screw down stop cock
of the ordinary so-called Rotherham pattern for water supply; Figure 1 being a
vertical section of the appliance, Figure 2 a side view of the clip part, Figure 3 a
plan view of the appliance and Figure 4 a section on line X X Figure 1.
A A are two clips having at their lower ends projections A'A' which pass under
a flange or other projecting part of the cock; A A² are upper projections on the
clips; these unite or adjoin above the spindle or upper part of the cock and have
each a hole A³ for a padlock or other locking device the key of which is kept by

page_text: some person in official charge of the cock. B is a box or housing passed over the
clips and having a hole for the legs A² to pass through and be locked as described
above the housing. A' is a lower projection from one or both clips for the purpose
of keeping the whole appliance in place on the cock. The projections A' instead of
taking under a flange or other projection on the cock may as shewn in dotted lines
in Figures 1 and 2 pass under the bottom of the cock.
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 :--
1. A stop cock locking appliance consisting of clips having each a lower
projection adapted to engage with some part of the stop cock the said clips
terminating at their upper ends in adjoining lugs, and a housing passing over the
clips and through which the lugs pass, such housing and clips being held in place by
રા padlock or other locking device connectable to the said lugs, substantially as set
forth.
2. The construction of stop cock locking appliance shewn on the drawings.
