Improvements relating to Gas Cocks.
I, FRANCES ANNIE FITZGERALD, of 32, Weighton Road, Anerley, S.E., in the
County of London, do hereby declare the nature of this invention to be as
follows:-
This invention for improvements relating to gas cocks has for its object to
enclose under lock and key gas turncocks, thus rendering a spanner, or any
instrument improvised for that purpose, useless until the lock up device has been
removed, and consists of a hollow cylinder divided longitudinally, by a plane
containing its axis, into two halves, two longitudinal edges of which are connected
together by a hinge while the opposite edges are provided with perforated lugs for
the purpose of securing the two halves together by means of a padlock, The
enclosing ends of the cylinder are pierced at their centres by circular apertures
varying in size according to the pipe or other fitting to be encircled.
By means of this invention the quantity of gas to be consumed can be fixed by
the householder, the gas cock being effectually locked up in the hinged cylinder
and cannot subsequently be altered by anyone until the apparatus is unlocked and
removed.

I, FRANCES ANNIE FITZGERALD, 32, Weighton Road, Anerley, S.E., in the
County of London, 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 for improvements relating to gas cocks has for its object to
enclose under lock and key, gas turncocks, thus rendering a spanner, or any
instrument improvised for that purpose, useless until the lock up device has been
removed.
In the accompanying sheet of illustrative drawings:-Fig. 1 represents a front
elevation of a lock up device in its open position and Fig. 2 is an end elevation of
the same.
A hollow cylinder is divided longitudinally into two halves ab by a plane
containing its axis and two contiguous longitudinal edges are connected together

page_text: by the hinge c' while the opposite edges are provided with perforated lugs or
loops de so that when the two halves are closed together the lug d passes between
the lugs e in which closed position they may be secured together by means of
a padlock passing through the holes g as shown. The enclosing ends of the
cylinder are pierced at their centres by circular apertures i varying in size
according to the diameter of the pipe or other fitting to be encircled. By means
of this invention the quantity of gas to be consumed can be fixed by the house-
holder, the gas cock being effectually locked up in the hinged cylinder, and
cannot subsequently be altered by anyone until the apparatus is unlocked and
removed.
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:-
1. A lock up device for gas cocks arranged and constructed substantially as
described and shown.
2. A lock up device for gas cocks comprising a hollow cylinder, in halves, hinged
together and capable of enclosing the gas cock substantially as described.
