Brass Worker do hereby declare the nature of my invention for "IMPROVEMENTS
IN CONNECTIONS FOR LEAD PIPES AND THE LIKE" to be as follows:-
.
The connections are fitted with Brass linings (A) made to metal pipe gauge (B)
taper in front (C) also taper at back (D) inside with a succession of hollows (E)
the lining is passed over the pipe its own length bearing most in the centre, a
taper tan pin is driven in the end of the pipe immediately filling up the hollows in
the lining also upsetting the pipe in front causing it to lock itself and forming a
tight joint in one piece without heat solder &c.

page_text: I FRANK GEORGE of 27 Northumberland Street Regents Park London
Middlesex Brass Worker do hereby declare the nature of my said invention for
"IMPROVEMENTS IN CONNECTIONS FOR LEAD PIPES AND THE LIKE
" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My Invention has for its object to provide means for fixing gas or other soft
metal pipes together or for connecting the said pipes to the pipes or nipple pieces
of meters or other apparatus in a ready rapid and efficient manner without the
use of solder or heating.
According to my said Invention the connections are fitted with sleeve pieces
technically called "linings" of relatively hard metal such for example as brass
made to the gauge of the pipe or pipes to be joined, and taper at the front part
and also taper at the back part of the inside and formed with a succession of
hollows grooves or recesses also in the inside. The said “lining" is passed over
the pipe for a length corresponding to the length of the said "lining" it bearing
most in the centre owing to the aforesaid double incline, and a taper tan pin or
expander is driven in the end of the pipe whereby the metal of the pipe is
expanded and immediately fills up the aforesaid hollows grooves or recesses in the
"lining" also upsetting the pipe in front and causing it to be locked in the said
"lining," thereby forming a tight joint in one piece without heat or solder.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same Letters of reference
indicating corresponding parts in all the figures.
Figure 1 represents in longitudinal section a connection for two soft metal pipes
made according to my Invention. Figure 2 is an external view of the same.
Figure 3 shews a longitudinal section of the aforesaid " lining" Figure 4 shews
the same with a pipe end inserted therein preparatory to expanding it thereinto
and Figure 5 represents one of the said linings with a screw socket of the ordinary
kind formed on it for attachment to a ball cock or a tap or the like.
Figure 6 illustrates pipes provided with the aforesaid linings attached to a
T piece.
The "lining" A (Figure 3) is made to the gauge of the pipe to be fixed therein
and is in its interior formed with a double taper that is to say, its internal
diameter is smaller in the centre (a) and widens out to a larger internal diameter
at both the ends (1, 2). In its interior are formed hollows grooves or recesses a
preferably of ratchet tooth form as shown the faces of the teeth being presented
towards the end of the pipe. The said lining is passed over the end of the pipe B
to be fixed in the said lining as shewn in Figure 4 and a tan pin or expander
being driven into the end of the pipe in the direction of the arrow the pipe is
upset or expanded and fills the interior of the said lining, and the hollows, grooves,
or recesses therein, and owing to these and the double taper aforesaid, the said
lining and pipe are firmly joined together, The said lining thus fixed to the pipe
forms the means of attachment of the pipe to another pipe or the like, such as the
short pipes projecting from gas meters, or from ball cocks, or valves, or taps, or
the like. Figures 1 and 2 shew two pipes connected by means of a screwed collar
or nut or what is known as a union coupling. The "linings on each of the pipes
are alike in their interiors but of course the one has on its exterior the ordinary
flange and the other the ordinary screw necessary for the said screwed collar or
23

page_text: nut. Figure 5 shews the lining formed with an internally screw socket for
attachment to a tap or other apparatus and Figure 6 shews three pipes fitted with
linings according to my Invention attached to a T piece it being understood that
I do not limit myself to any particular means by which the "linings fixed to
pipes according to my Invention are fixed together, or to the apparatus to which
they are to be connected.
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:-
First Alining" or sleeve piece for fixing to pipes (as a means of connection)
by expanding the pipe end thereinto the said "lining" or sleeve piece being
formed with double inclines on its interior, that is to say, being of smaller
diameter at its central part and expanding to a larger diameter at its outer ends
substantially as hereinbefore described.
Second: A " lining" or sleeve piece for fixing to pipes (as a means of
connection) by expanding the pipe end thereinto, the said "lining," or sleeve piece
being formed with hollows, grooves, or recesses in its interior, into which the end
of the pipe to be connected can be expanded substantially as herein before
described.
Third As a means of connection for pipes the hereinbefore described "lining"
or sleeve piece formed with double inclines and with hollows, grooves, or recesses
in its interior, into which the end of the pipe to be connected can be expanded
substantially as hereinbefore described.
Fourth A coupling or connection for pipes, connecting of a "lining" or sleeve
piece on each pipe, these linings or sleeve pieces being formed as bereinbefore
described and claimed by either of the preceding claiming clauses, and connected
together substantially as hereinbefore described and illustrated by Figures 1 and 2
of the accompanying drawings.
