Improvements in Means for Securing in Position and Protecting
from Injury the Heat Non-conducting Material or Outer Covering
of Boilers, Pipes, Cylinders, and other Articles.
I, RICHARD BARTON of 18 Commercial Road, Hull, in the County of York,
Manufacturer do hereby declare the nature of my Invention to be as follows:-
My Invention relates to boilers, pipes, cylinders, or other bodies which are covered
or protected by means of fossil meal, papier maché, asbestos or other non-conducting
material and has for its object to provide means by which the said material is very
efficiently kept in place and prevented from becoming detached or of an unequal
thickness at different portions of the article and from being damaged by blows or
otherwise.
By my Invention also dry or powdered non-conducting material can be efficiently
held in place against or around the boiler, pipe cylinder, or other article.
According to my Invention I apply to the outside of the boiler, pipe, cylinder or
other article to be protected metal straps which carry at suitable intervals projections
or studs. These straps are fastened or clamped around the boiler, pipe, cylinder, or
other article to be protected. I apply outside these a metal sheathing preferably of
thin sheet steel or iron. The space between the sheathing and the boiler, pipe,
cylinder or other article to be protected is occupied by the protective material to
be employed.
The studs may project outwardly from the straps, the latter being in contact with
the boiler, pipe, cylinder or other article and the sheathing placed outside the studs,
or the said studs may project inwardly from the straps and in contact with the article
and the outer sheathing being applied to the straps.

Improvements in Means for Securing in Position and Protecting
from Injury the Heat Non-conducting Material or Outer Covering
of Boilers, Pipes, Cylinders, and other Articles.
I, RICHARD BARTON, of 18 Commercial Road, Hull, in the County of York,
Manufacturer, 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 :-

page_text: My Invention relates to boilers, pipes, cylinders or other bodies which are covered
or protected by means of fossil meal, papier maché, asbestos, or other non-conducting
material and has for its object to provide means by which the said material is very
efficiently kept in place and prevented from becoming detached and from becoming
of unequal thickness at different portions of the article; and from being damaged by
blows, or otherwise.
By my invention also dry or powdered non-conducting material can be efficiently
held in place against or around the boiler, pipe, cylinder, or other article.
According to my invention I surround, or partly surround, the outside of the
boiler, pipe, cylinder, or other article, to be protected, by a sheathing, or jacket, and
maintain the said sheathing at the desired distance from the outer surface of the
boiler, pipe, cylinder, or other article, by means of distance pieces, which may
consist of metal straps, carrying at suitable intervals projections, or studs. These
straps are fastened or clamped around the boiler, pipe, cylinder, or other article, to
be protected. The sheathing, or jacket is preferably of thin sheet steel, or iron. The
space between the sheathing and the boiler, pipe, cylinder, or other article, to be
protected, is occupied by the protective material employed.
The studs may project outwardly from the straps, the latter being in contact with
the boiler, pipe, cylinder, or other article, and the sheathing be placed outside the
studs, or the said studs may project inwardly from the straps and be in contact with
the article and the outer sheathing be applied to the straps.
Figure 1 of the accompanying drawings represents partly in elevation and partly in
longitudinal section, portions of two lengths of pipe provided with a protective covering,
or sheathing, according to my invention, and Figure 2 is a transverse section of
the pipe and protective sheathing drawn to a larger scale. In the description of the
drawings I refer to pipes but it will be understood my invention is also applicable
similarly to boilers, cylinders and other articles.
On the pipe to be protected, I clamp, or otherwise secure, at suitable distances
apart, metal straps, or bands, A, preferably with a layer of asbestos between the said
straps or bands and the surface of the pipe, to prevent the transmission of heat from
the pipe to the said straps, or bands. The straps, or bands, A, are preferably made in
parts to facilitate placing them in position on the pipe, B, the parts being rivetted,
screwed, or otherwise, connected together, so as to cause the bands A to clip the
pipe.
Projections are provided on each metal strap, or band, A, which projections may consist
of studs connected to the strap, or band, by rivets, or otherwise, or they may be formed
as shewn in Figure 2 by strips of metal A2, corrugated, or bent, so as to form
projections a at suitable distances apart; the strips A2, being rivetted to the straps or
bands A. The straps or bands, A, with the projections thereon, are secured to the
pipe at suitable distances apart and over these projections a is placed the sheathing,
or jacket, B2, which may be made of thin steel in one piece, or it may be divided
longitudinally, as shewn, to facilitate placing the said sheathing in position, the parts
being connected together by rivets, bolts and nuts, or by any other suitable fastenings,
metal strips b being provided at the joints to strengthen the sheathing at these
parts. The distance pieces, whether they be provided with studs, or with projections,
formed by the corrugated strips A2, as shewn, ensure the sheathing, or jacket, being
maintained at the desired uniform distance from the surface of the pipe enclosed
thereby. In the space C, between the pipe and the jacket, or sheathing, A, is placed
heat non-conducting material of any suitable kind; and the ends of the space C, may
be closed by plugs c, of any suitable material to prevent the escape of the heat non-
conducting material. To prevent, or reduce, the transmission of heat from the
pipe, B, through the straps, or bands, A, and studs, or projections a, these may be
interposed between the straps, or hands, and the surface of the boiler, cylinder, or
the like layers of asbestos, or other suitable heat non-conducting material as shewn
at a².
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :—

page_text: 1. For protecting from injury and securing in position the heat non-conducting
material, or outer covering, of boilers, cylinders, pipes, and other articles, the
combination of a metal sheathing and distance pieces constructed, and arranged,
substantially as hereinbefore described.
2. For protecting from injury and securing in position the heat non-conducting
material, or outer covering of boilers, cylinders, pipes, and other articles, the
combination of a sheathing, or outer casing, enclosing the heat non-conducting, or
like material; metal straps, or bands, fixed, or clamped, to the boiler, cylinder, pipe,
or the like, to be protected, studs, or projections, on the said metal straps, or bands,
to support, and maintain, the sheathing at the required distance from the surface of
the boiler, cylinder, pipe, or the like, substantially as hereinbefore described.
3. For supporting sheathing, or outer casings, of boilers, cylinders, pipes and other
articles; distance pieces constructed substantially as hereinbefore described and
illustrated by the accompanying drawings.
