PROVISIONAL SPECIFICATION.
Improvements in Covering for Steam Pipes, Cylinders, or the like,
to Prevent Radiation of Heat.
1, EDWIN JONES of Hyde in the County of Chester, Manufacturer of Boiler
Covering do hereby declare the nature of the said invention to be as follows:-
This invention is primarily designed to provide an efficient and durable covering
to prevent radiation of heat for steam pipes but it may also be applied to cylinders
boilers or other like structures.
A sheet iron ring is provided of about an inch in width and to the inner surface
of this ring are attached two three or more angular or other pieces projecting
therefrom with narrow bearing surfaces or points to rest upon the shell of the
pipe or cylinder. This ring or band is made to encircle the pipe at some distance
from it and only bearing upon it at intervals.
Around the ring so placed is applied a sheet iron casing of a size to enclose
about or of the circumference of the pipe leaving a corresponding space or
opening. The casing rests upon the ring or band previously secured in position.
Through the opening in the casing the interior space around the pipe is stuffed
or packed with slag wool or other material being a non-conductor of heat.
When so stuffed or packed the intervening space is also covered and over it is
placed a sheet or cover of sheet metal which is held in position over the aperture
in the preceding cover by clamps rings bolts rivets screws or other fastening device.
Above the metal casing an additional coating of non-conducting material may be
applied if desired.
When applied to boilers or cylinders the inner rings need not completely encircle
the structure but may be made in the form of a strip the ends being secured to the
brick work masonry or foundations the slag wool is then applied as before and
covered with the sheet metal covering which can be secured by bolts or screws or
other lastenings.

Improvements in Covering for Steam Pipes, Cylinders, or the like.
to Prevent Radiation of Heat.
I, EDWIN JONES, of Hyde, in the County of Chester, Manufacturer of Boiler
Covering, 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 :-
This invention is primarily designed to provide an efficient and durable covering
to prevent radiation of heat for steam pipes but it may also be applied to cylinders
boilers or other like structures.

page_text: It consists essentially in the combination with a metallic or other casing for
enclosing a covering of slag wool or other non-conducting material of rings of
sheet iron or other rigid material of about an inch in width and provided with two
three or more strips or lugs projecting or radiating therefrom with narrow bearing
surfaces to rest upon the shell of the pipe or cylinder.
It will be fully described with reference to the accompanying drawings.
Fig. 1. side elevation of length of pipe covered in accordance with my invention.
Fig. 2. longitudinal section of same.
Fig. 3. transverse section.
Fig. 4. plan partly in section.
Upon the pipe A to be covered or protected I place at intervals a ring B of
sheet iron or other rigid material provided with two or more preferably three feet
or angular supporting pieces C projecting or radiating inwardly therefrom. The
supporting pieces C have narrow bearing surfaces to rest against the pipe A and
maintain the ring B in position concentrically around it. The ring B may be
about one inch wide or other suitable width or may be made of wire or other stiff
material.
The ring B is placed to encircle the pipe A with the projecting or supporting
pieces Cresting against it.
Around the ring B is applied a casing D of sheet iron or other suitable material
of a size to enclose about or of the circumference of the pipe leaving a
corresponding space or opening E. The casing rests upon the ring B previously
secured in position.
Through the opening E in the casing D the interior space a around the pipe A
is stuffed or packed with slag wool or other material being a non conductor of
heat. When so stuffed or packed the intervening space is covered by a lid Fof
sheet metal which is held in position over the aperture in the preceding cover by
clamps or rings G bolts rivets screws or other fastening device.
The sheet metal casing D is preferably cut away at d to allow of the nuts of the
flange bolts being screwed up or unscrewed without removing the casing.
Above the metal casing an additional coating of non conducting material may be
applied if desired.
When applied to boilers or cylinders the inner rings need not completely encircle
the structure but may he made in the form of a strip the ends being secured to the
brick work masonry or foundations the slag wool is then applied as before and
covered with the sheet metal covering which can be secured by bolts or screws or
other fastenings.
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 1
claim is :-
1. In a covering for steam pipes and other structures the combination with the
non conducting material and the outer casing of rings or hoops of metal or other
material with radiating or projecting pieces to rest on the pipe or structure to
support the outer casing concentrically substantially as described.
2. A covering for steam pipes, cylinders, and other structures to prevent
radiation of heat constructed and arranged in combination substantially as
described.
