AN IMPROVED JOINT FOR STEAM AND OTHER PIPES to be as follows:-
Year: 1888

page_text: I, NEIL GILMOUR HARAN of 28 New Street, Paisley, in the County of Renfrew,
North Britain, Plumber, do hereby declare the nature of this invention for "AN
IMPROVED JOINT FOR STEAM AND OTHER PIPES to be as follows:-
"
This Invention which relates to an improved joint for steam and other pipes, has
for its object to make the joint, steam, air or water tight, without the use of packing,
consists in forming the end of one of the pipes requiring to be connected partly
spherical or semi-ball shaped, the rounded or ball part being by preference considerably
larger in diameter than the external diameter of the rest of the pipe or tube, and
finishing with a flange or circular ring.
The extremity of the other pipe is provided with a cup shaped seat into which the
rounded or ball part of the first mentioned pipe exactly fits. The two pipes are then
connected in the well known manner from small wrought iron, brass or copper piping
by means of a screwed coupling and jam nut, the ball by this method being forced
tightly into its seat, and so preventing the escape of air, water or steam.
By the use of the packing hitherto employed in pipe jointing, considerable incon-
venience was experienced by the said packing becoming broken, thu necessitating
the frequent repair of the pipe joints, and consequently expense and loss of business.
Dated this 28th day of February 1888.

page_text: 1, NEIL GILMOUR HARAN of 28 New Street Paisley in the County of Renfrew,
North Britain, Plumber 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 which relates to an Improved joint for steam and other pipes has
for its object to make the joint, steam, air, or water tight, without the use of packing.
My Improvement consists in forming the end of one of the pipes requiring to be
connected partly spherical or semi-ball shaped, the rounded or ball part being by
preference considerably larger in diameter than the external diameter of the rest of
the pipe or tube and finishing with a flange or circular ring.
The extremity of the other pipe is provided with a cup shaped seat into which the
rounded or ball part of the first mentioned pipe exactly fits. The two pipes are then
connected in the well known manner for small wrought iron, brass, or copper piping
by means of a screwed coupling and jam nut. The ball by this method is forced
tightly into its seat and so prevents the escape of air, water or steam.
By the use of the packing hitherto employed in pipe jointing considerable incon-
venience was experienced by the said packing becoming broken, thus necessitating
the frequent repair of the pipe joints, and consequently expense and loss of business.
In order that my Invention may be most fully understood and readily carried into
effect, I will proceed to describe the drawings hereunto annexed :-
Figs. 1. and 4 are longitudinal sections of a pipe joint constructed according to and
constituting my present Invention.
Figs. and are respectively an elevation and a plan of the pipe arrangement
represented at Fig. 1.
In carrying out the objects of this Invention the joint end of pipe A is
mado partly spherical or semi-ball shaped, the said rounded portion A¹ being
slightly larger in diameter than the external diameter of the body of the pipe A.
Immediately beyond this rounded portion A¹ an external circular flange A" is formed
on the pipe A to prevent the said pipe from being forced out of its seat when the
joint is made. The joint end of pipe B is provided with a cup shaped seat B¹ into
which the rounded part A¹ of pipe A exactly fits. The two pipes A and B are then
connected in the well known manner for small wrought iron brass, or copper piping
by means of a screwed union or coupling C, and jam nut D, a part of the external
surface of pipe B being screw-threaded to suit. By screwing up the coupling C and
jam nut D, the rounded end A¹ of pipe A is forced tightly into its seat B¹ thereby
making a perfect joint, and preventing the escape of air, water, steam, or any other
fluid that may be contained within the pipes A and B. It is to be understood that I

page_text: do not confine myself to the particular form of bends A and B shewn on the
accompanying drawings, but that the pipes A and B may be straight or otherwise as
desired.
Having now particularly described and ascertained the nature of my said Inven-
tion & in what manner the same is to be performed, I declare that what I
claim is :-
The rounded end A' of pipe A fitting into the cup shaped seat B' of pipe B sub-
stantially as & for the purpose hereinbefore set forth with reference to the annexed
drawings.
