PROVISIONAL SPECIFICATION.
Water Gauge Glass Protector for Steam Boilers.
I, SAMUEL GEORGE DYER of Newtown Yeovil in the County of Somerset
Locomotive Engine Driver, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the protection of water gauge glasses on steam boilers
the object of the invention being to afford protection from the escape of steam and
water in the event of the gauge glass breaking.
My said invention consists of a circular protector made in two halves and fixed
to the gauge cocks with an india rubber, steam tight joint. The front part of the
protector consists of semicircular glass half inch thick, and the back of metal.
The top and bottom are also composed of metal with a recess cast on to which the
glass fits. A metal frame is screwed on over the edges of the glass to secure it.
A pipe will be tapped into the bottom of protector to convey the escaping steam
and water underneath the footplate.

I SAMUEL GEORGE DYER of 14 Newtown Yeovil in the County of Somerset
Locomotive Engine Driver 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 protection against accident in the event of the bursting
of water, gauge glasses on steam boilers, having for its direct object the prevention
of broken pieces of glass and escaping steam and water from injuring any person or
persons who may be in close proximity.
In ordered that my invention may be clearly rendered, reference may be had to
the accompanying sheet of drawings in which Figure 1 is an internal plan view
and Figure 2 a front elevation of the gauge glass protector.
Similar letters of reference are used to indicate like parts in both views.
In constructing a protector according to my invention I employ a metal back
marked A Figure 1 which fits behind the water gauge glass, also a front marked B
composed of a metal fraine, and glazed with glass half inch thick C. the joint
between the glass and metal being made with india rubber.
There are two lugs marked F Fig. 2 cast on the back into which are tapped two
studs also two corresponding lugs with holes drilled in same are cast on the front
part. The faces of both the front and back of protector are planed so as to make
a tight joint, the two parts being kept firmly together by means of two butterfly
nuts screwed on to the aforesaid studs. The part of protector which fits around
the nuts of gauge cocks marked D Fig. 1 is turned to fit the same.
Also a wire guard E is fixed inside the protector immediately around the front
of the gauge glass.

page_text: Escape pipes G are tapped into both the top and bottom sides of the protector
and a perforated cap marked H Fig. 1 is screwed on to prevent the pipe from being
choked. The escape pipes may be arranged so as to conduct the escaping steam
and water to any suitable place.
The action of the protector is as follows:-In the event of the gauge glass
breaking, the escaping steam and water immediately issues through the aforesaid
escape pipes whilst the pieces of broken glass are arrested by the protector and
thus an accident to any person or persons in close proximity is prevented.
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 :-
66
First. A metal and glass protector to prevent accident in the event of a steam
boiler water gauge glass" bursting.
Second. A wire guard to be fixed around the front of gauge glass inside the
protector as an additional protection.
