PROVISIONAL SPECIFICATION.
Improvements in and connected with Shields for Steam Water
Gauges.
I, REUBEN THOMAS PRESTON, of the Firm of J. Stone & Co., of Deptford, in
the County of Kent, Engineers, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object to diminish the dangers arising from the
bursting of gauge glasses and so prevent scalding by steam or hot water and injury
from broken glass, and also to give greater facilities for removing the shield or
protector when this is required in order to replace a broken gauge glass.
To effect this I provide a horse-shoe or other suitably shaped shield of annealed
glass or other suitable transparent or translucent material, covering and protecting
the front and sides of gauge; this glass is secured in a top and bottom frame with
a hinged joint allowing the shield with its framing to be thrown out of its fixed
position and so give clear access to the gauge; or the shield may be slided over
suitable pieces at top and bottom of gauge frame, or I may form a hinged joint so
that the shield and frame may be hinged at one side. The fastening for this shield
may be provided with a spring or ball and socket catch for the purpose of readily
opening and closing same.

COMPLETE SPECIFICATION.
Improvements in and connected with Shields for Steam Water
Gauges.
I, REUBEN THOMAS PRESTON of the Firm of J. Stone & Co. of Deptford in
the County of Kent Engineers 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 has for its object by the employment of a shield or protector to
diminish the dangers arising from the bursting of gauge glasses and so to prevent
scalding by steam or hot water and injury from broken glass and also to give great
facility for removing the shield when this is required in order to replace a broken
gauge glass. To effect this I provide a horseshoe or equivalently shaped shield of
annealed glass or other suitable transparent or translucent material, covering and
protecting the front and sides of gauge glass. This shield is secured in a top
and bottom frame with binged joint allowing the shield with its framing to be
thrown out of its fixed position and so give clear access to the gauge: or the shield
may be slided over suitably projecting pieces at top and bottom of gauge frame ;
or I may form a hinged joint so that the shield and frane may be hinged at one
side. The fastening for this shield may be provided with a spring or bolt and
socket catch for the purpose of readily opening and closing same.

page_text: Fig. 1 on the accompanying drawing is a part sectional side view of a gauge
adapted for and fitted with my gauge glass shield or protector and Fig. 2 is a
front elevation of same.
Fig. 3 is a plan view of the frame or plate wherein the upper end of the
shield fits,
Fig. 4 a plan view of the hinge frame wherein the lower end of the shield fits
and rests and
Fig. 5 a plan view of the lower gauge glass fitting.
A is the gauge glass which is held in the upper and lower gauge glass fittings B
and C in the usual manner. The fittings B and C are of usual form_except as
regards the additional part B' which can be slided on the fitting B and the
additional part C which forms an integral part of the fitting C; both are adapted
to receive the horseshoe shaped shield D and are shown in the plan views Fig. 3
and Fig. 5 respectively. The shield fits at the top in a recess in the part B' but
at the bottom it fits and rests in a recess in a hinge piece E shown in plan in Fig. 4.
This hinge piece has at its outer end a lower hinge lug E which fits between the
two hinge lugs C* C* provided on the part C₁ and its inner ends terminate in
hinge lugs Ex Ex which fit over the hinge lug C** on the part C¹. The upper
hinge parts C** E* C** are held together by the detachable hinge pin F while
the lower hinge parts C* E' C* are held together undetachably by the pin H.
The frames B and E are united by two rods G. When the hinge pin Fis
taken out, the shield D held in its upper frame B' and lower frame E can be
swung out around the hinge pin H, and the gauge glass removed or exchanged as
required.
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. The application and use in steam water gauges of a removable shield of
horseshoe or equivalent form for protection against injury in case the gauge glass
breaks substantially as set forth.
2. The adaptation of steam water gauges to render same suitable for receiving a
shield of the character described for the purpose set forth.
3. The construction of steam water gauge with shield held in a hinged framing
substantially as described. with reference to the drawing.
