Complete Accepted, 22nd July, 1887,
I, ARNOLD BUDENBERG of 1 Southgate Manchester in the County of Lancaster
Mechanical Engineer do hereby declare the nature of this invention to be as follows:-
This Invention relates to Steam and similar pressure Gauges of the "Bourdon"
type and more particularly to those having steel tubes, and it has for its object to
protect the metal of the tubes from the chemical or analogous action of the fluids to
which they may be exposed.
For the purpose of this Invention the interior of the tube is plated or coated with a
metal which is not chemically or similarly acted upon by the fluid to which it has to
be exposed.
It is in all cases desirable to effect the metallic plating or coating of the tube after
it has been reduced to the proper form and finally screwed or otherwise secured into
the fittings forming part of the guage, as in this case the plating or coating will tend
also to protect the joints and the interior of the fittings. The outer part of the tube
and of the fittings may also be similarly coated or plated.

page_text: I, ARNOLD BUDENBERG of 1, Southgate Manchester in the County of Lancaster,
Mechanical 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 :-
This Invention relates to Steam and similar pressure gauges of the "Bourdon"
type and more particularly to those having steel tubes and it has for its object to
protect the metal of the tubes from the chemical or analogous action of the fluids to
which they may be exposed.
For the purpose of this Invention the interior of the tube is plated or coated
with a metal or alloy which is not chemically or similarly acted upon by the fluid
to which it has to be exposed. It is in all cases desirable to effect the metallic
plating or coating of the tube after it has been reduced to the proper form and finally
screwed or otherwise secured into the fittings forming part of the gauge, as in this
case the plating, or coating will also protect the joints and the interior of the
fittings. The outer part of the tube and of the fittings may also be similarly coated
or plated.
For ordinary purposes it will generally be found most economical and useful to
coat, plate or cover the surfaces of the tubes and the contiguous parts of the fittings
with tin for special circumstances other metals and alloys may be used such as nickel,
aluminium-bronze or gold. The method or methods of effecting the coating plating
or covering are such as are ordinarily employed in analogous operations and form no
part of these Improvements.
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 :-
Plating or coating the tubes of "Bourdon," "steel tube" and similar pressure
gauges with metal; substantially as and for the purpose hereinbefore set forth.
