PROVISIONAL SPECIFICATION.
Improvements in Covering Steam and other Pipes and Vessels for
Protection against Radiation, Frost, and Wet.
1, WILLIAM OUTTERSON WOOD of South Hetton in the County of Durham Mining
Engineer do hereby declare the nature of this invention to be as follows:-
-
The object of my invention is to provide a heat non-conducting covering, which
shall be cheap, efficient, casily applied and durable and which also affords protection
against frost and wet.
According to my invention I apply wood of any suitable kind, in suitable sections
over and in combination with hair felting, asbestos, asbestos paper, slag wool or other
analogous nonconducting substance. This substance as applied for instance to the
covering of a pipe I employ in one or more pieces arranged longitudinally and by
preference use it perforated at or near the edge of each side with suitable holes so as
to be expeditiously secured to the said pipe or other surface by lacing. Or it may be
for instance attached to the pipe or other surface by any suitable adhesive compound
or the said covering may be wrapped spirally round such surface to be covered, or
may be laid on in patches and secured by means of string or wire lappings.
This first covering I surround with neatly fitting sectional strips of wood hollowed
out on the inside, and flat or curved on the outside and whose lengths are preferably
equal to the distance between the flanges. For the purpose of securing the wood
sections in position I use suitable metallic hoops by preference of wrought iron
provided with lugs or knees and screwed bolt, and in number according to the
length and diameter of pipe. And I also cover the flanges with short sectional
strips of wood the said strips resting on those already fixed to the pipes. These
strips may be hollowed out to fit over the flange in order to reduce the size of the
covering to its minimum proportions. These strips are also secured by means of a
hoop or hoops.
Between the flange and its wood covering strips I prefer to interpose flannel or
the like so as to secure a close fitting joint and this will be especially valuable
in wet mine shafts and in steam drifts or in case of vertical or inclined over-
ground pipes.

Improvements in Covering Steam and other Pipes and Vessels for
Protection against Radiation, Frost, and Wet.
I, WILLIAM OUTTERSON WOOD of South Hetton in the County of Durham Mining
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 object of my invention is to provide a heat non-conducting covering for the
flange part and body part of steam and other pipes and vessels which covering shall
be cheap, efficient, easily applied and durable and which also affords protection against
frost and wet.
According to my invention I apply wood of any suitable kind in suitable sections
over and in combination with hair felting, asbestos, asbestos paper slag wool or other
analogous, non-conducting substance. This substance as applied for instance to the

page_text: covering of a pipe I employ in one or more pieces arranged longitudinally and by
preference use it perforated at or near the edge of each side with suitable holes so as
to be expeditiously secured to the said pipe or other surface by lacing. Or it may
be for instance attached to the pipe or other surface by any suitable adhesive
compound or the said covering may be wrapped spirally round such surface to be
covered or may be laid on in patches and secured by means of string or wire
lappings.
This first covering I surround with neatly fitting sectional strips of wood hollowed
out on the inside and flat or curved on the outside and whose lengths are preferably
equal to the distance between the flanges for the purpose of securing the wood
sections in position. I use suitable metallic hoops by preference of wrot iron
provided with lugs or knees and screwed bolt, and in number according to the length
and diameter of pipe.
An important part of my invention consists in covering the flanges of steam and
other pipes and vessels with short sectional strips of wood the said strips resting on
the woodlagging or other covering of the body of the pipe. These strips may be
hollowed out to fit over the flange in order to reduce the size of the covering to its
minimum proportions and are or may be secured by means of a hoop or hoops.
Between the flange and its wood covering strips I interpose flannel or the like so as
to secure a close fitting joint and this will be especially valuable in wet mine shafts
and in steam drifts or in case of vertical or inclined overground pipes. This flange
covering is easily detachable when required and forms with the covered pipe a
continuous covering thus entirely preventing radiation. The flange covering is
applicable to existing covered pipes.
Figure 1 of the accompanying drawings is a longitudinal section of a pipe
provided with the flange covering and body covering according to this invention
figure 2 is a cross section half on line A B and half on line CD and figure 3 is
a side view. The flanges ff are covered with wood strips which are held
together by a metallic loop d with flanges and a screw bolt and nut e. The strips b
are hollowed out to fit over the flanges and a piece of flannel felt asbestos paper
or the like it interposed to make a close fitting joint. The strips & may be fixeu to
the hoop d. The pipe body is in this case shewn covered with felt wrapping c or the
like, and wooden strips a which are held together by means of hoops d' with bolts
and nuts e. But I may as stated use the flange covering in connection with any
other suitable kind of covering to the body part of the pipe or vessel.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. A protecting covering for flanges of pipes and vessels consisting of wood
strips secured by a metallic hoop and with interposed lining of flannel or the like
substantially as set forth.
Second. The protecting flange and body covering described with reference to the
accompanying drawings.
