page_text: Improvements in or relating to Sleeves for Pipe Joints.
I, JOHN JONES, of 40, Sydney Street, Chelsea, in the County of Middlesex,
Sanitary Specialist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pipe joints, its object being the construction of a sleeve
for ready application to the exterior of a joint around two pipes or two tubular
portions, such for instance as the boss outside a water closet pan and the water pipe
leading into that boss.
It is an important feature of such a sleeve according to this invention that it
is constituted by an outer portion of canvas or equivalent flexible or elastic material,
lined with indiarubber, or a substance of a like nature adapted to fit closely about
the joint so as to prevent any leakage of fluid.
Such a sleeve may be cylindrical, or its bore may vary at different portions of
its length; it may, for instance, be conical or tapered or composed of large and
small ends merging into one another between those ends. Corrugations or beads
may be formed upon the outside or inside as desired.

Improvements in or relating to Sleeves for Fipe Joints.
I, JOHN JONES, of 40, Sydney Street, Chelsea, in the County of Middlesex,
Sanitary Specialist, 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 pipe joints, its object being the construction of a sleeve
for ready application to the exterior of a joint around two pipes or two tubular
portions, such for instance as the boss outside a water closet pan and the water pipe
leading into that boss.
It is an important feature of such a sleeve according to this invention that it
is constituted by an outer portion of canvas or equivalent flexible or elastic material,
lined with indiarubber, or a substance of a like nature adapted to fit closely about
the joint so as to prevent any leakage of fluid.
Such a sleeve may be cylindrical, or its bore may vary at different portions of
its length; it may, for instance be conical or tapered or composed of large and

page_text: small ends merging into one another between those ends. Corrugations or beads
may
be formed upon the outside or inside as desired.
In the accompanying drawings:-
Figure 1 is a perspective view of the improved sleeve.
Figure 2 is a longitudinal section of the same.
Figure 3 is a perspective view of another construction.
Like letters indicate like parts throughout the drawings.
The sleeve is made up of a rubber body A provided with an outer layer B of
canvas or similar flexible or elastic material having a stretching limit, the canvas
being attached by solutioning or otherwise as found convenient. Beads A¹ are
formed at either end of the rubber body, the canvas being preferably carried over
and partially round these beads as shown at B¹.
The sleeve illustrated is of two different diameters, being adapted for enclosing
a joint between two pipes of different sizes.
If desired the canvas may be arranged in one or more bands as shown in Figure 3.
Here a band is arranged round the central part of the sleeve where the greatest
pressure is felt.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;-
-
1. The complete sleeve for pipe joints substantially as described or illustrated
in the accompanying drawings.
2. In a sleeve for pipe joints the combination with an indiarubber body of an
outer layer of canvas or similar material having a stretching limit substantially
as described.
3. In a sleeve for pipe joints the combination with an indiarubber body of one or
more outer layers or bands of canvas substantially as described.
