PROVISIONAL SPECIFICATION.
Improvements in Removable Non-conducting Coverings for Pipe
Flanges.
SARTORIUS RHeinhold, Celle Hannover Germany do hereby declare the
nature of this invention to be as follows :-
A contrivance by means of which flanges of pipes that are covered with a
non-conducting material to prevent radiation of heat can also be provided with a
covering which being easily removed allows free access to any part of the flange &
yet possesses good isolating powers.
The annexed diagram shews in Fig. I a longitudinal, in Fig. No. II a vertical
section & in Fig. III a general view. Round the two flanges f1 /2 of the
tubes R1 R2 which are covered with the non-conducting composition I¹ I² the
isolating flange covering is put, which is divided lengthways consisting of the two
halves FF; the vertical section shews this figure In isolating valves an
opening is left in the covering to allow for the handling of the hand wheel without
that the coating has to be removed. Any non-conducting material or a composition
of several isolating materials can be used for this flange covering provided it has
the neceesary binding capacities & is fire proof. Round each half of the coating
a cover A' A' is laid made from card board, canvas etc. the ends of which overlap
& thus protect the joint of the two halves. The two halves may be held together
by any suitable clasp or other contrivance. Two zinc straps B1 B2 are used which
being provided with a kind of buckle allow of their being tightened or loosened
like an ordinary strap. Of course any other contrivance can fulfil the same
purpose provided it permits of the covering being removed easily so that in case any
defects shew on the flanges they can easily be examined & put right. The two
tubes ele allow the steam to escape in case of any deficiency thus also pointing out
at once any defect in the flange.

SARTORIUS RHEINHOLD, Celle, Hannover, Germany 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 :-
A contrivance by means of which flanges of pipes that are covered with a
non-conducting material to prevent radiation of heat can also be provided with a
covering which being easily removed allows free access to any part of the flange &
yet possesses good isolating powers. The diagram filed with my Provisional
Specification shews in Fig. I a longitudinal, in Fig. II a vertical section & in
Fig. III a general view. Round the two flanges f1/2 of the tubes R R 2 which
are covered with the non conducting composition I'I' the isolating flange covering
is put which is divided lengthways consisting of two halves F1 F2, the vertical
section shews this figure . In isolating valves an opening is left in the covering
to allow for the handling of the hand wheel without that the coating has to be
removed. Any non conducting material or a composition of several isolating
materials can be used for the flange covering provided it has the necessary binding
capacities & is fire proof. Round each half of the coating a cover A' A³ is laid

page_text: made from cardboard cavass etc., the ends of which overlap and thus protect the
joint of the two halves. The two halves may be held together by any suitable
clasp or other contrivance. Two zinc straps B1 B2 are used which being provided
with a kind of buckle allow of their being tightened or loosened like an ordinary
strap. Of course any other contrvance can fulfil the same purpose provided
it permits of the covering being removed easily, so that in case any defects shew on
the flanges they can easily be examined and put right. The two tubes el e allow
the steam to escape in case of any deficency thus also pointing out at once any
defect in the flange.
Having now particularly described & 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:
It is a contrivance by means of which flanges of pipes that are already covered
with a non-conducting material to prevent radiation of heat can also be provided
with a covering which is easily removed, allows free access to any part of the flange
and yet possesses good isolating powers.
