COMPLETE SPECIFICATION.
Improvements in Guards for Water Guages having a Mirror
Attachment.
I, SAUNDERSON HENRY STURTEVANT of 90 Charlotte Road, Shoreham Street, Sheffield
in the County of York, Engineer, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN GUARDS FOR WATER GAUGES" and in what manner the same is to
be performed to be particularly described in and by the following statement:
This invention relates to improvements in water gauges having a mirror attachment,
such improvements preventing any injury to the engine tenter or other person when
replacing the gauge glass or at any other time.
In the construction of this invention I take a half tube made of brass, iron or
other suitable metal formed by bending or casting, as shown in the accompanying
drawings, for the purpose of forming a guard, and which covers about three parts of
the gauge glass.
This guard is secured in flanges held by screws to the top and bottom nuts, which
nuts hold the gauge glass securely to the taps. In the bottom of the tube is a slot
to receive a wedge to be able to fasten the tube or guard on to the bottom
flange.
Placed on the small of the gauge taps are brass clamps to hold the frame and
mirror which mirror can be put at any angle by a small thumb screw passing through
the frame on to a pin belonging to the said clamp.
The said mirror is placed at the back of the gauge glass and may be formed flat
or circular.
The said guard may be polished or plated inside, to show more clearly the reflection
of the water line in the mirror.

claim is :-
-
Improvements in the method of protecting gauge glass and to prevent injury to
the engine tenter or other person when replacing the same or at any other time by
means of a guard made of brass, iron or other suitable metal, placed in front, and
being able to read the water line by means of the reflection seen in a mirror placed
at the back thereof the whole being secured as described, specified and as illustrated
by the accompanying drawings.
