An Improved Joint for Steam Pipes and the like,
I, RODGER REAY, of Lintleydale, Haltwhistle, in the County of Northumber-
land, Engineer, do hereby declare the nature of this invention to be as follows:-
In order to better describe my invention I have made drawings of the same
which are shewn in Fig. 1 and Fig. 2. I am not bound to sizes as shewn to
scale, but I may make the parts either larger or smaller as may be required.
In Fig. 1 I shew the adjoining ends of the pipes P, P, which have their ends
turned up as shewn at B1, B3. I place over the joint a suitable ring B of iron,
steel, or other material. Against the outer sides of B B and B I place a ring of
rubber, asbestos, or any other suitable material in the position indicated by C, C.
The rings A, A, which are loose, and are shewn on each side of the joint J, are
then drawn closely up against the rings or washers C, C, and I insert bolts D, D,
into holes which are made in A, A, and fix on the nuts E, E, and thus screw or
tighten up the rings A, A, against the rings or washers C, C, making thereby a
steam tight joint, all substantially as shewn in Fig. 1.
In Fig. 2 I shew another form of joint involving the same principle, and in
this figure the adjoining ends of two pipes are shewn, but only one of the pipe
ends is turned up as shewn at B. Against the outer side of B¹ and also of the
projection on B I place a ring or washer of rubber, asbestos or other suitable
material in the position indicated by C.
I then as in Fig. 1 draw the ring A which is loose, against the ring or washer C
and I insert bolts D, D, into holes which are prepared for them in A, B, and I
fix on the nuts E, E, and screw or otherwise tighten up the ring A against the
ring or washer C, thereby making a steam tight joint substantially as shewn in
Fig. 2.

I, RODGER REAY, of Lintleydale, Haltwhistle, in the County of Northumber-
land, 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:-
In order to better describe my invention I have made drawings of the same
which are shewn in Fig. I and Fig. II and which were left with the Provisional
Specification

page_text: In Fig. I I shew the adjoining ends of two pipes P, P, which have their ends
turned up as shewn at B', B₁. 1 then place over this joint a suitable ring B of
iron, steel, or other material and against the outer sides of B B B¹. I place a
ring or washer of rubber, asbestos or any other suitable material in the position
indicated by C. C. The rings A A which are loose and are shewn on each
side of the joint J are then drawn closely up against the rings or washers CC
and I insert bolts D, D, into holes which are made in the rings A A and fix
on the nuts E E and thus screw or tighten up the rings A A against the rings or
washers C, C, making thereby a steamtight, airtight, and watertight joint sub-
stantially as shewn in Fig. 1.
In Fig. II I shew another form of joint involving the same principle, and in
this figure the adjoining ends of two pipes P, P, are shewn but only one of these
pipe ends is turned up as shewn at B, the other being turned up and formed as
shewn at B. Against the outer side of B¹ and also of the projection on B I
place a ring or washer of rubber, asbestos or any other suitable material in the posi-
tion indicated by C. I then, as in Fig. I draw the ring A, which is loose, against
the ring or washer C and I insert bolts D, D, into holes which are made for them
in the rings A, B, and I fix on the nuts E, E, and screw or otherwise tighten up
the ring A against the ring or washer C, thereby making a steamtight, airtight,
and watertight joint substantially as shewn at Fig. II.
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. An airtight, steam tight and watertight joint connecting two pipes, formed
substantially as shewn in Fig. I and II.
2. A joint connecting two pipes for any fluid at high or low pressure or tem-
perature, formed substantially as described.
3. In Fig. I the ring B of iron, steel, or other material placed over the junction
of two pipes P, P, at B', B', substantially as shewn and described.
4. In Fig. I the arrangement of washers C C of rubber, asbestos, or any other
suitable material placed against the sides of B₁ B₁ and B substantially as shewn
and described.
5. In Fig. I the combination of the ring B with the washers C, C, applied
to B B for the purpose of forming a joint as shewn and described.
6. In Fig. II the specially made end B of the pipe P substantially as shewn
and described.
7. In Fig. II the arrangement of washer C, of rubber asbestos, or any other
suitable material placed against ends of B and B substantially as shewn and
described.
8. In Fig. II the combination of the specially made end B of pipe P, with the
washer C to form a joint between two pipes P P substantially as shewn and
described.
