COMPLETE SPECIFICATION.
Improvements in Insulating Coverings for Steam Pipes.
I, JOSEF KESSEL, of 43, Oberstrasse, Dusseldorf, in the Empire of Germany,
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:-
The present invention relates to a new insulating covering for steam pipes,
and consists in the form of construction which is clearly set forth in the following
specification.
In the accompanying drawing:
Fig. 1, is a longitudinal section of a pipe fitted with my improved covering.
Fig. 2, is a transverse section on the line c d of Fig. 1.
Fig. 3, is a transverse section on the line ab of Fig. 1.
Fig. 4, is a plan view of one half of the plate or flange which serves to secure
the extremity of the covering.
The new covering, which is formed of any suitable material, is of a cylindrical
shape, and is provided upon its lower face with spiral shaped ribs or projections 1
(Fig. 1,) so that there will exist between the insulated pipe and the covering of
insulating material a hollow space wherein the vapours of condensation water etc.
can collect. Such a covering admits of the free expansion of the insulated
pipe and increases the resistance of the insulating covering. The extremity of
this latter may be fixed or secured in any convenient manner, but
employ a circular plate or flange 2, which consists of two halves or parts easily
connected together and provided with a vertical annular projection forming a
socket adapted to receive and hold the extremity of the insulating piece or
covering.

The insulating covering may likewise be formed with a smooth interior surface
so as to enable it to be slipped on and over the spiral ribs or projections, which
latter have been previously and independently applied to the pipe to be protected,
to the insulating covering. The said ribs or projections may be formed of any
suitable material.
The connecting joints of two steam pipes will be insulated by a cap or box 4
also formed in two parts or halves and provided with lugs 5 by means of which
these halves or parts can be easily connected together. In order to admit of the
discharge of the water resulting from condensation, which may be found between
the covering and the insulated pipe, one of the halves or parts of the closed cap
or box 4 may be fitted with a small discharge pipe.
The flat part of the cap or box 4 may be provided with a plane surface, or be
provided with a circular strengthening rib in which will engage or rest the
adjacent extremity of the insulating covering 1.
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:-
1. An insulating covering for storm.

of increasing the resistance of the covering and of providing an air jacket or
layer of air between the different ribs or projections.
2. A form of construction of the insulating material such as that claimed in
the first claim characterized by the insulating material possessing a smooth interior
surface so as to enable it to be slipped on and over the spiral ribs or projections
which latter are applied to the steam pipe itself.
3. A removable insulating cap or box for the coupling or connecting joints
of steam pipes, consisting of two hollow halves or parts of any suitable material
provided with connecting lugs, one of the two halves or parts being, if desired,
fitted with a small discharge pipe.
4, The insulating covering for steam pipes, constructed and applied sub-
stantially as hereinabove described, and as illustrated in the accompanying
drawing.
Dated this 24th day of November: 1900.
