Sectional Non-conducting Covering for Steam Pipes and Flanges.
We, EDWARD SPICER, of 54, Warner Road, Camberwell, S.E., and CHARLES
WILLIAM COLTHRUP, of 54, Ondine Road, East Dulwich, S.E., both in the County
of Surrey, Foreman and Departmental Manager respectively, and SNOWDON SONS
AND COMPANY LD., of Westferry Road, Millwall, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
We take a sheet of asbestos or other non-conducting material, any length, in
width half the diameter of the pipe (Fig. 3, C), which we moisten and bend to
the shape of the pipe. We then take asbestos or other rings, Fig. 4, B (the inside
diameter of which, is a little larger than the pipe, the outside diameter may be
any size, which we may find suitable for any pipe in particular) and cut them in
halves and fasten them on the outside of the bent sheet of asbestos or other
material, perpendicularly, about two inches apart. We then take another sheet
of asbestos or other non-conducting material (Fig. 4, A) of the same length as the
other sheet, but the width to be the same as the outside circumference of the
half rings, to which we also fasten it, having first moistened it, to get to the same
shape. By this means we create an air-space Fig. 3, I between the half rings,
which can be left as it is, or filled with fossil meal or other non-conducting
material.
We take another section, made exactly the same, and fix canvas round both,
then place them round the pipe and secure them to it by means of bands.
The flange covers are made in the same way, with sheet asbestos and half rings
of the same, (Fig. 1, E) or any other non-conducting material. We also cover the
two finished halves, with canvas, and fix them round the flange, by bands, in the
same way as the pipe sections.
Figure 1, represents one half of flange cover finished, and the other half un-
finished in order to show our idea of the half rings forming an air space.
Figure 2, shows the application of the device to the flange covers.
Figure 4, shows the first stage of the pipe section.
Figure 3, shows the second stage, and Figure 5 shows half a section as it appears
when finished.

page_text: mental Manager respectively, and SNOWDON SONS & COMPANY LIMITED, of West-
ferry Road, Millwall, Manufacturers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention has for its object the production of a sectional non-conducting
covering for steam pipes and flanges; and, in order that the nature of the same
may be the better, understood we would refer to the drawings accompanying our
Provisional Specification in which :-..
Figure 1 is intended to represent our improved flange cover ready for use one
half being shewn finished and the other half unfinished in order to illustrate the
arrangement of half rings we employ in forming the non-conducting packing space
or receptacle hereinafter described..
Figure 2 is intended to shew the application of our improved non-conducting
cover to steam pipe. flanges..
Figures 3, 4 and 5 illustrate the various stages of construction of a se
a sectional
non-conducting pipe cover according to our improvements; Figure 4 shewing the
first stage in the construction; Figure 3 the second stage and Figure. 5 shewing
half a section as it appears when finished.
In carrying out our invention we take a sheet C Figure 3 of asbestos or other
non-conducting material of any length, and in width preferably half the diameter
of the pipe, which sheet we moisten and bend to conform to the shape of the pipe.
We then take asbestos or other non-conducting strengthening rings or partitions B
Figure 4 (the inside diameter of which rings is a little larger than that of the
pipe, whilst the outside diameter may be of any size we may find suitable for any
particular pipe)-and cut them in halves and fasten them in any convenient manner
on the outside of the bent sheet C above referred to of asbestos or other material
perpendicularly to the axis of the pipe and at distances of two inches apart or
thereabouts. We then take another sheet A Figure 4 of asbestos or other non-
conducting material of the same length as the first sheet C whilst the width is
the same as that of the outside circumference of the half rings B to which we also
fasten it having first moistened it to get it to the same shape.
By this means we are enabled to produce a non-conducting covering for steam
pipes in which we create or provide a packing space or receptacle D Figure 3
between the half rings B and the outer sheet of asbestos A and the inner sheet C,
this packing space or receptacle D being filled with fossil meal or other non-con-
ducting material.
We then repeat this operation and take another section made exactly the same,
and by preferably fixing canvas round both sections adapt same to the pipe and
secure them together by means of bands or other convenient fastenings, or if
desired the two sections may be hinged together as shewn Figures 1 and 2. in
connection with the non-conducting pipe flange covers constructed in accordance
with our invention which are made preferably in the same manner as applies in
the case of above described cover for pipes with sheet asbestos and half rings E
Figure 1 of the same or any other non-conducting material.
We may also hinge the two finished halves of the flange cover together to facili-
tate attachment, and, or, cover same with canvas and fix them around the flange
in the same way as applies in the case of the cover for pipes, and secure them
either by canvas wrappings, by bands or buckles as shewn or other similar con-
venient means.
By the employment of the inner and outer bent asbestos sheets A, C, so arranged,
as described and shewn, that an annular space or receptacle D or series of annular
packing spaces or receptacles D) is or are created therebetween, and by the use of
the strengthening rings B and E are enabled to produce a highly efficient, in-
expensive, non-conducting cover for steam pipes and flanges, which by the sectional
arrangement of construction and manner and means of fastening can be readily
and economically fitted to existing pipes and flanges, the receptacle 1 being filled

page_text: with fossil meal or other non-conducting material whilst the rings B as arranged
not only serve to strengthen the cover but prevent the displacement or shifting
of the fossil meal or other non-conducting material to the end of the section.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim and desire to secure by Letters Patent is:-
First. A sectional non-conducting covering for steam pipes and flanges con-
structed and arranged as herein set forth.
Second. In a sectional non-conducting covering for steam pipes and flanges the
method of and means employed for creating or providing a receptacle D for con-
taining fossil meal or other non-conducting material so as to entirely surround
or envelope the pipe and flange comprising two sheets A, C, of asbestos or other
non-conducting material bent to conform to the shape of the pipe or flange the said
receptacle or packing space 1 between the sheets A and C having strengthening
non-conducting rings B and E arranged therein all as hereinbefore more particu-
larly described and shewn.
Third. In a sectional non-conducting covering for steam pipes and flanges com-
prising bent sheets A, C, concentrically arranged to provide a packing space or
receptacle D for containing fossil meal or other non-conducting material and
having strengthening rings B and E therebetween-the method of and means
employed for joining and securing same together when adapted to the pipe by
hinging, canvas wrappings and bands or other means of fastening substantially as
described and shewn.
Fourth. In a sectional non-conducting covering for steam pipes and flanges the
combination of the parts A, C, B, E, to form a receptacle or packing space D for
containing non-conducting material such as fossil meal or the like, such recep-
tacle 1) and packing material therein entirely surrounding the pipe and flange,
substantially as and for the purposes specified.
