I, JAMES WILLIAM BLACKBURN of 9 Wallner Theaterstrasse, Berlin, in the-
Empire of Germany, Machine Agent, do hereby declare the nature of this invention.
to be as follows:-
This invention relates to improvements in the method of and means employed for
"jacketting" steam pipes, the object being to form an air space around such pipes,.
thus preventing loss of heat by radiation, and the "jacketting" being outside the
air space, the air in the latter prevents the jacketting being burnt, charred, or
cracked, by the heat of the steam pipe. The improved jacketting is cleaner
and more durable, and is an effective protection against radiation of heat.
According to this invention, a spiral or helical spring or springs, is or are.
wrapped spirally or helically around the steam pipe, such spring or springs being
pulled or stretched whilst being wound around the pipe, so as to be open or
extended, and the elasticity maintains the spring or springs in the required position
when the ends are secured to the pipe by wire or otherwise.
The spring or springs when wrapped around the pipe, are covered with a non-
conducting material such as felt, or asbestos, which is secured by stitching or
wrapping with wire. There is thus an air space formed around the steam.
pipe, such air space being protected from the outer air by the non-conducting
material.

Improvements in the Method of and Means Employed for
"Jacketting" Steam Pipes and the like.
I, JAMES WILLIAM BLACKBURN, of 9 Wallner Theaterstrasse, Berlin, in the
Empire of Germany, Machine Agent, 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 relates to improvements in the method of and means employed for
"jacketting" steam pipes, the object being to form an air space around such pipes,.
thus preventing loss of heat by radiation, and the "jacketting" being outside the
air space, the air in the latter prevents the jacketting being burnt, charred, or
cracked by the heat of the steam pipe. The improved jacketting is cleaner
and more durable, and is an effective protection against radiation of heat.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,.
in which :-

helically around the pipe.
Fig. 2 is a sectional end view of Fig. 1.
According to this invention, a spiral or helical spring or springs 1. 1 is or are
wrapped spirally or helically around the steam pipe 2, such spring or springs 1. 1
being pulled or stretched whilst being wound around the pipe 2, so as to be open or
extended, and the elasticity maintains the spring or springs in the required position,
when the ends of such spring or springs are secured to the pipe by being tied with
wire or otherwise.
The spring or springs 1 when wrapped around the pipe 2, are covered with a non-
conducting material 3, such as felt, or asbestos, the edges of which are secured by
stitching or wrapping with wire. There is thus an air space 4 formed around the
steam pipe 2, such air space being protected from the outer air by the non-
conducting material 3.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
A "jacketting" for steam pipes and the like, consisting of a spiral or helical
spring wound spirally or helically around the pipe, and a covering of felt, asbestos,
or other non-conducting material wrapped around the pipe and over the spring,
as herein described, and substantially as illustrated by the annexed drawings.
Dated this 2nd day of April 1896.
