IMPROVEMENTS IN 'CONNECTIONS FOR LEAD OR OTHER LIKE PIPES
Year: 1884

page_text: I FRANK GEORGE of 27 Northumberland Street Regents Park in the County of
Middlesex Brass Worker do hereby declare the nature of my said Invention for
" IMPROVEMENTS IN 'CONNECTIONS FOR LEAD OR OTHER LIKE PIPES
to be as
follows:-
My Invention has for its object to provide a very simple and efficient means for
connecting lengths of lead or other soft metal pipes together or to gas meters or
other apparatus without the necessity for using solder or a number of auxiliary
parts such as has hitherto been the practice.
According to my Invention I provide for each end of the pipes to be joined a
sleeve piece technically termed a "lining" which has in its interior a double taper
so that the front and hinder portions are slightly larger than the mid portions.
In the interior of each of these linings I form a number of grooves or recesses
preferably of a ratchet tooth shape in section the toothed or ledged part being
presented towards the front part of the nozzles.
On the end of the pipes to be joined being inserted into their linings and a taper
expander being driven into the said ends the material of the pipes is driven into
the grooves in the linings and is caused to fill completely the interiors of the said
linings with their double inclines so that the linings are by these means firmly
fixed to the said pipes. The front end of one of the linings is splayed or widened
out and over this splayed or widened out part the extreme outer part of the
material of the pipe end inserted into the said lining as spread by the expandor.
The other lining has a taper reduced end piece at its forward part which enters
and bears upon the metal of the pipe splayed out as aforesaid at the end of the
opposed lining. The aforesaid taper reduced end piece may be milled or toothed
so as to bite into the soft metal of the splayed out end of the pipe in the opposed
lining. The linings are secured together by means of a screw nut or other
convenient means of attachment by which the two linings are forced firmly together
in joining the pipes. In joining a pipe to a gas meter or other apparatus the one
lining only may be used on the end of the pipe to be joined the other part of the
connection being formed upon or carried by the Gas meter or other apparatus.

I- FRANK GEORGE of 27 Northumberland Street Regents Park in the County of
Middlesex Brass Worker do hereby declare the nature of my said invention for
"IMPROVEMENTS IN CONNECTIONS FOR LEAD OR OTHER LIKE PIPES," and in what
Dianner 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 a very simple and efficient means for
connecting lengths of. lead or other soft metal pipes together or to gas meters or
other apparatus without the necessity for using solder or a number of auxiliary
parts such as has hitherto been the practice. According to my Invention I provide
for each end of the pipes to be joined a sleeve piece technically termed a "lining"
which has in its interior a double taper so that the front and hinder portions are
slightly larger than the mid portions.
In the interior of each of these linings I form a number of grooves or recesses
preferably of a ratchet tooth shape in sections the toothed or ledged part being
presented towards the front part of the nozzles.
On the end of the pipes to be joined being inserted into their linings, and a taper
expander being driven into the said ends, the material of the pipes is driven into
the grooves in the linings and is caused to fill completely the grooves in the
interiors of the said linings, with their double inclines, so that the linings are by
these means firmly fixed to the said pipes. The parts thus far resemble the subject
matter of my application for Patent No 2984 of the 8th February 1884 but in
addition to this and according to my present Invention the front end of one of the
linings is splayed or, widened out as shewn at b in Figure 1 (which is a longitudinal
section of two pipes connected by linings formed according to my present Invention)
and over this splayed or widened out part the extreme outer part of the material
of the pipe end, inserted into the said lining, is spread by the expander as shewn
at c. The other lining has a taper reduced end piece at its forward part as shewn
at d which enters and bears upon the metal of the pipe splayed out at c as aforesaid
at the end of the opposed lining. The aforesaid taper reduced end piece d.
may be
milled, roughened, or toothed on its outside, so as to bite into the soft metal of the
splayed out end c of the pipe, in the opposed lining. The linings are secured
together by means of a screw, collar, coupling or nut as shewn or by any other
convenient means of attachment by which the two "linings are fixed firmly
"
together in joining the pipes. Figure 2 is a longitudinal section of a slightly
modified form of the lining in which the flange against which the screw collar bears
is set inwards to accommodate a washer 6. In joining a pipe to a gas meter or
'other apparatus, the one lining only may be used on the end of the pipe to be
'joined, the other part of the connection being formed upon, or carried by the Gas
meter or other apparatus. Figure 3 shews a pipe and "lining" formed with a
splayed or widened out part (b. c.) as hereinbefore described attached to a short
pipe projecting from the apparatus (a gas meter for example) to which the pipe is
to be connected. The nipple piece d is in this case formed on the said short pipe f.
Figure 4 shews a T piece to which are connected pipes and "linings" formed with
splayed or widened out parts (b. c.) as hereinbefore described the nipple pieces din
this case being formed on each end of the T piece to which the pipes are joined.
Figure 5 shews a pipe and lining formed with a splayed or widened out part (b. c.)
as hereinbefore described and formed with an ordinary screw socket for receiving
the short screwed pipe or projection of a ball cock or tap or the like the nipple d in
this case being formed at the end of the said screwed pipe or projection.

page_text: 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-Connections for joining lengths of lead pipes or the like, to other lengths
of lead pipes or the like, or to gas meters.or other apparatus to which the pipes are
to be connected, the said connections consisting of a "lining" having double
inclines, or grooves, or recesses, in its interior, (or both the said inclines and the
said grooves or recesses) and a splayed or widened out end, into which the pipe ond
is upset or splayed out, in combination with a conical or nipple piece on an opposed
lining" or other part to which the pipe is to be joined, substantially as herein-
before described.
Second-Connections for joining lengths of lead pipes or the like, to other
lengths of lead pipes or the like, or to gus meters or other apparatus to which the
pipes are to be connected, the said connections consisting of a "lining" having
double inclines, or grooves, or recesses in its interior, (or both the said inclinos and
the said grooves or recesses) and a splayed or widened out end, into which the pipe
end is upset or splayed out, in combination with a conical or nipple piece on an
opposed "lining," or other part to which the pipe is to be joined, the exterior of the
said conical or nipple piece being inilled, roughened, or toothed, on its outside to
bite into the metal of the opposed, splayed out pipe end, substantially as herein-
before described.
