PROVISIONAL SPECIFICATION.
An Improved Means of Fixing Shields for Water Gauge Glasses.
I, HOWARD FIELD of 12 London Street London E.C. Engineer do hereby
declare the nature of this invention to be as follows:-
For the purpose of my invention I use a shield of glass or other suitable material
of a semicircular or other suitable shape & at each end of this shield I fix a
piece of metal of the form of one half of a hinge, like the hinge of a door or gate.
I then take two small pieces of sheet metal rather longer than the width of the
gauge cocks and turned down or having small lugs at each end so that when laid
across the gauge cocks the lugs clip the cocks on either side. I place one of these
pieces on the top side of the bottom gauge cock, and one on the under side of the
top gauge cock. I then take a rod or tube, in length equal to the distance
between the two plates, and screw it at one end & put a nut on. I then place the
rod between the two plates, one end against each, & turn the nut until it jambs
the rod tightly between the two plates, the two plates being jamhed firmly between
the two cocks. The plates may be slightly recessed to allow the ends of the rod
to enter, thereby holding it more firmly. On the rod I bolt or otherwise fix two
arms or cross pieces one end of each cross piece forming the duplicate half of
the hinge to that on the shield. I then hinge the shield on to the cross pieces by
bringing the two halves of the hinges together viz. those on the shield to the
corresponding halves on the cross pieces, & putting in a bolt. The other end of
the cross arm forms a clasp, or catch, a fellow to which is fixed on the shield.
I thus have a shield, surrounding or partially surrounding the gauge glass, which
prevents injury to any person through the breakage of the gauge glass and which
can be thrown back on its hinges clear of the gauge glass thereby enabling an
attendant to take out or renew a gauge glass without having to detach the shield
from the cocks.

An Improved Means of Fixing Shields for Water Gauge Glasses.
I, HOWARD FIELD, of 12 London Street, London, E.C. 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 :-
My invention relates to the fixing of shields for water gauge glasses, which I
effect as I shall describe referring to the accompanying drawings. Fig. 1 is a
front elevation and Fig. 2 is a sectional plan of a shield fixed according to my
invention.
I use a shield A of glass or other suitable material of a semicircular or other
suitable shape and at each end of this shield 1 fix a piece of metal B B¹ of
hinge form. I then take two small pieces of metal D D' rather longer than the
width of the gauge cocks C C³ and turned down or having small lugs at each end so
Price ed

page_text: that when laid across the gauge cocks C C the lugs clip the cocks on either side.
I place one of these pieces D on the top, side of the bottom gauge cock C, and
the other D¹ one on the under side of the top gauge cock C. On the lower
piece DI form a boss d.internally threaded to receive a screw F having a circular
recess in its head. I then place a rod or tube E with its one end in the recess of
the screw F and its other end in a similar recess of D and turn the screw' F until
the rod E is tightly jamned between the two plates which are thus jamned firmly
against the two cocks CC. On the rod or tube E 1 fix two crossheads G G' to
the ends of each of which is held by pins the hinge piece B B. I thus have a
shield A partly surrounding the gauge glass, which prevents injury to any person
when the gauge glass breaks, and which can be thrown back on its hinges clear of
the gauge glass as indicated by the dotted lines in Fig. 2, thereby enabling an
attendant to take out or renew a gauge glass without having to detach the shield
from the cocks. I have shewn the gauge cocks C C of rectangular section; when
they are round, I make the pieces D D¹ of circularly curved form as shewn in
Fig. 3 to fit against the cocks.
Having now particularly described. and ascertained the nature of this inven-
tion and in what manner the same is to be performed; I declare that what I
-claim is :-
"For fixing a gauge glass shield, a rod or tube clamped between the upper and
lower gauge cocks and carrying a pair of crossheads to which are jointed pieces of
hinge form attached to the ends of the shield, substantially as described.
