I, JAMES RILEY, General Manager to The Steel Company of Scotland, Limited,
of 150 Hope Street, Glasgow, in the County of Lanark, North Britain, do hereby
declare the nature of this Invention to be as follows, that is to say :-
My said Invention has for its object the making of steel pipes in an improved
manner, and whilst it is applicable for making pipes of various sizes, it is more
especially intended for pipe lengths of large size made with with spigot and faucot
ends for connecting one to another.
In carrying out the Invention the body of a pipe length is made of sheet steel and
with a longitudinal welded or riveted joint. The faucet is made out of a circular flat
steel plate by a stamping or embossing process or by a combination or succession of
such processes. The precise details of the stamping process or processes may be
varied in practice, but I at present believe the best way of effecting the operations to
be as follows:-The plate is laid on a table which can be raised by an hydraulic
cylinder and which has on it an annular cutter or ring arranged to cut with its inner
edge. Above the plate there is a stationary annular cutter or ring arranged to cut
with its outer edge; and when the table raises the plate the rings sever the circular
disk from the outer parts of the plate. The table returns down to a fixed position,
and then a die block of suitable form is forced downwards by an hydraulic cylinder
and operating in combination with a suitable counter die or recess in the table
gradually gives a cup-like form to the steel disk the sides of the cup ultimately
forming the socket part of the faucet piece. By a subsequent process a circular picco
is punched out of the bottom of the cup and then the remaining annular part of the
bottom is by hydraulic pressure stamped or embossed to form the neck of the faucet
piece. The faucet piece is fixed by its neck to the body of the pipe length either by
riveting or by expanding the end of the body so as to become locked in the neck.
The spigot may be formed by fixing a cylindrical ring on the other end of the pipe
length either by riveting or by expanding the body.

I, JAMES RILEY, General Manager to The Steel Company of Scotland, Limited,
formerly of 150 Hope Street, now of 23 Royal Exchange Square, Glasgow in the
County of Lanark, North Britain, 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, that is to say :-
My said Invention has for its object the making of steel pipes in an improved
manner, and whilst it is applicable for making pipes of various sizes, it is more
especially intended for pipe lengths of large size made with spigot and faucet or other
ends for connecting one to another.
In carrying out the Invention the body of a pipe length is made of sheet steel and
with a longitudinal welded or riveted joint. When the end parts for forming the
joints for connecting the pipe lengths together are of the spigot and faucet kind, the
faucet is made out of a circular flat steel plate by a stamping or embossing process or
by a combination or succession of such processes. The precise details of the stamping
process or processes may be varied in practice but 1 at present believe the best way
of effecting the operations to be as hereinafter particularly described with the aid of
explanatory drawings upon three sheets which are hereunto appended.
Figure, 1, on sheet, 1, of the accompanying drawings is a vertical section showing
the acting parts of an hydraulic machine for effecting the first stage of the operations
for forming a faucet; and figures, 2, and 3, on sheet, 2, are vertical sections of parts
for effecting subsequent stages. Figure, 4, is an enlarged section explanatory of one
mode of fixing the faucet on the pipe lengths. Figures, 5, and 6, on sheet, 3, are
vertical sections of modified parts for forming flanged rings or pipe ends. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
When two or more faucets are to be made out of an oblong plate small centre
holes are first punched in the plate at suitable distances apart to serve as guides in
placing the plate in the machine partly shown in figure, 1. The plate, 7, is laid on a
table or block, 8, in such a position that a centering mandril, 9, can be lowered into
a centre hole previously punched in the plate. There is fixed on the table or block, 8,
an annular steel cutter, 49, arranged to cut with its inner edge; and above the
plate, 7, there is an annular steel cutter, 10, arranged to cut with its outer edge,
and which is fixed to a massive frame piece, 11, connected by bolts, 12, to the bed
frame, 13. The table or block, S, is raised by the ram, 14, of an hydraulic
cylinder, 15, and makes the cutter rings, 49, 10, sever a circular disk from the outer
parts of the plate, 7. The ram, 14. is next lowered and the table, or block, 8, returns
down to a fixed position, and then a die block, 45, of suitable form is forced down by
the ram, 16, of an inverted hydraulic cylinder (which is not shown) and operating in
combination with a suitable counter die or recess, 17, in the table or block, 8,
gradually gives a cup-like form to the steel disk, the sides of the cup ultimately

page_text: forming the socket part of the faucet piece. The upper die, 45, is held down, and
the bottom ram, 14, is raised again and carrying with it a central die, 18, therewith
punches a circular piece out of the bottom of the cup. The body of the centering
mandril, 9, is made of the same size as the central die, 18, below; and the mandril, 9,
being fitted into a recess in the upper die, 45, retires up into that recess when the
upper die descends. The faucet piece so far as formed in this first machine is
shown at, 19.
The faucet piece, 19, as shaped by the first machine has a turned-in flange at its
smalter end, and this flange is stamped or bended out into a cylindrical form by tools
such as are shown in figure, 2. Attached to the ram, 20, of an inverted hydraulic
cylinder, there is a die block, 21, shaped to fit in the socket part of the faucet.
piece, 19, which is held in a lower block, 22, and at the bottom end of the block, 21,
there is attached a die, 23, which latter forces out the flange when the hydraulic ram
descends. When the upper block, 21, has reached the bottom of the socket part, the
lower die, 23, is loosened from it by drawing out a transverse pin, 24, and the upper
block, 21, being raised struts or distance pieces are interposed between it and the
lower die, 23. The hydraulic ram, 20, is then lowered again and forces the lower
die, 23, completely through the faucet piece, 19, and leaves it below when the ram is
raised again, allowing the faucet piece to be easily removed.
When a faucet is required to have a taper internally so that its socket part is
slightly contracted at the outer end for the purpose of retaining lead or other
material used to make the joint tight, I subject the faucet piece, 19, to the action of
tools shown in figure, 3, which also remove irregular projecting parts from the
circumference of the large end of the faucet piece. The ram, 25, of an inverted
hydraulic cylinder has attached to it a block, 26, to which there is fixed an upper
steel cutting ring, 27; and this ring acts in concert with a stationary cutting ring, 28,
fixed on a block, 29. The upper cutting ring, 27, has its bottom shaped to fit the
rounded mouth and the lower part of the block, 26, to fit in the socket part of the
faucet piece in order to insure its being concentric when the outer rim is being cut.
In figure, 3, the parts are shown in the positions they have when the cutting of the
outer rim has just been completed. When this has been done the hydraulic ram, 25,
is raised with the block, 26, and struts or distance pieces, indicated by dotted lines
at, 30, are interposed between the block, 26, and the faucet piece, 19. The central
opening in the stationary block, 29, is made, with a contracting taper; and when
downward pressure is again applied the faucet piece, 19, is forced downwards through
the taper opening, and its outer part is thereby made to contract.
The faucet piece, 19, may be fixed to the end of the pipe length by riveting but
when the pipes are not large, say not more than 24 inches in diameter, 1 prefer to fix
it by expanding the end of the pipe length, 31, in the neck of the faucet piece in the
manner indicated in figure, 4, which is an enlarged section. The expanding tools are
applied so as to enlarge the extreme end, 32, of the pipe length, 31, into the inner
end of the socket part of the faucet piece. 19, and also to form an enlargement, 33,
just beyond the end of the neck of the faucet piece in order to lock the parts together.
Whilst expanding the end of the pipe length in the faucet piece the neck of the
latter is confined externally.
The spigot may be formed by fixing a cylindrical ring on the other end of the
pipe length either by riveting or by expanding the end of the pipe length in the ring.
When the end parts for forming the joints for connecting the pipe lengths together
are to have flanges, they are made in the form of flanged rings by means of suitably
modified apparatus shown in figures, 5, and 6, on sheet, 3. The plate, 7, figure, 5, is
first cut into a circular disk by means of a stationary steel cutting ring, 49, acting
with its inner edge in concert with the outer edge of a steel cutting ring, 10, fixed
to a block, 45, attached to the ram, 16, of an inverted hydraulic cylinder. When the
outer edge of the disk has been cut, or whilst it is being cut, a central die, 18, is
moved up by the ram, 14, of a lower hydraulic cylinder, and acting in concert with
the inner edge of the upper cutting ring, 10, punches out a circular hole in the
plate, 7, so as to form a flat ring. The flat ring is next transferred to the apparatus

page_text: shown in figure, 6, and is subjected to an operation like that applied to the faucet
piece (19) in the apparatus shown in figure, 2. A die, 23, attached to a block, 21,
which is attached to the ram, 20, of an inverted hydraulic cylinder is made to act on
the flat ring supported on a stationary block, 22, which is made with a central
aperture of a diameter the same as that intended to be given to the outside of the
cylindrical part of the flanged ring. The die, 23, is made to descend and it gradually
forces the inner part of the flat ring down into the central aperture of the block, 22,
until its shape is converted into that of a flanged ring, 34. The bottom of the
block, 21, descends upon the outer part of the ring and insures that part being
finished in the proper flat form for a joint flange. When the block, 21, has been
forced down to its lowest position with the die, 23, in the ring, 34, the die, 23, is
loosened, the block, 21, raised, and struts or distance pieces interposed between them;
and then the ram, 20, is moved down again and forces the die, 23, completely
through the ring, 34.
The flanged ring, 34, may be fixed on the end of the pipe length by riveting or by
expanding the end of the pipe length within it, as shown in section at 35.
In the various stamping or embossing operations hereinbefore described, the steel
acted upon is heated if required.
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
1 claim is
The making of steel pipes with end pieces formed out of plates by stamping
or embossing processes and by apparatus substantially such as is hereinbefore described.
2 The fixing of end pieces on steel pipes by expanding the ends of the pipe
lengths in the end pieces substantially as hereinbefore described.

Improvements in Making Steel Pipes.
1, JAMES RILEY, General Manager to The Steel Company of Scotland, Limited,
formerly of 150 Hope Street, now of 23 Royal Exchange Square, Glasgow in the
County of Lanark, North Britain, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and

My said Invention has for its object the making of steel pipes in an improved
manner, and whilst it is applicable for making pipes of various sizes, it is more
especially intended for pipe lengths of large size made with spigot and faucet or other
ends for connecting one to another.
In carrying out the Invention the body of a pipe length is made of sheet steel and
with a longitudinal welded or riveted joint. When the end parts for forming the
joints for connecting the pipe lengths together are of the spigot and faucet kind, the
faucet is made out of a circular flat steel plate by a stamping or embossing process or
by a combination or succession of such processes. The precise details of the stamping
process or processes may be varied in practice but I at present believe the best way
of effecting the operations to be as hereinafter particularly described with the aid of
explanatory drawings upon three two sheets which are hereunto appended.
Figure, 1, on sheet, 1, of the accompanying drawings is a vertical section showing
the acting parts of an hydraulic machine for effecting the first stage of the operations
for forming a faucet ; and figures, 2, and 3, on sheet, 2, are vertical sections of parts
for effecting subsequent stages. Figure, 4, is an enlarged section explanatory of one
mode of fixing the faucet on the pipe lengths. Figures, 5, and 6, on sheet, 3, are
vertical sections of modified parts for forming flanged rings or pipe ends. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
When two or more faucets are to be made out of an oblong plate small centre
holes are first punched in the plate at suitable distances apart to serve as guides in
placing the plate in the machine partly shown in figure, 1. The plate, 7, is laid on a
table or block, 8, in such a position that a centering mandril, 9, can be lowered into
a centre hole previously punched in the plate. There is fixed on the table or block, 8,
an annular steel cutter, 49, arranged to cut with its inner edge; and above the
plate, 7, there is an annular steel cutter, 10, arranged to cut with its outer edge,
and which is fixed to a massive frame piece, 11, connected by bolts, 12, to the bed
frame, 13. The table or block, 8, is raised by the ram, 14, of an hydraulic
cylinder, 15, and makes the cutter rings, 49, 10, sever a circular disk from the outer
parts of the plate, 7. The ram, 14, is next lowered and the table, or block, S, returns
down to a fixed position, and then a die block, 45, of suitable form is forced down by
the ram, 16, of an inverted hydraulic cylinder (which is not shown) and operating in
combination with a suitable counter die or recess; 17, in the table or block, S,
gradually gives a cup-like form to the steel disk, the sides of the cup ultimately

page_text: forming the socket part of the faucet piece. The upper die, 45, is held down, and
the bottom ram, 14, is raised again and carrying with it a central dio, 18, therewith
punches a circular piece out of the bottom of the cup. The body of the centering
mandril, 9, is made of the same size as the central die, 18, below; and the mandril, 9,
being fitted into a recess in the upper die, 45, retires up into that recess when the
upper die descends. The faucet piece so far as formed in this first machine is
shown at, 19.
The faucet piece, 19, as shaped by the first machine has a turned-in flange at its
smaller end, and this flange is stamped or bended out into a cylindrical form by tools
such as are shown in figure, 2. Attached to the ram, 20, of an inverted hydraulic
cylinder, there is a die block, 21, shaped to fit in the socket part of the faucet.
piece, 19, which is held in a lower block, 22, and at the bottom end of the block, 21,
there is attached a die, 23, which latter forces out the flange when the hydraulic ram
descends. When the upper block, 21, has reached the bottom of the socket part, the
lower die, 23, is loosened from it by drawing out a transverse pin, 24, and the upper
block, 21, being raised struts or distance pieces are interposed between it and the
lower die, 23. The hydraulic ram, 20, is then lowered again and forces the lower
die, 23, completely through the faucet piece, 19, and leaves it below when the ram is
raised again, allowing the faucet piece to be easily removed.
When a faucet is required to have a taper internally so that its socket part is
slightly contracted at the outer end for the purpose of retaining lead or other
material used to make the joint tight, I subject the faucet piece, 19, to the action of
tools shown in figure, 3, which also remove irregular projecting parts from the
circumference of the large end of the faucet piece. The ram, 25, of an inverted
hydraulic cylinder has attached to it a block, 26, to which there is fixed an upper
steel cutting ring, 27; and this ring acts in concert with a stationary cutting ring, 28,
fixed on a block, 29. The upper cutting ring, 27, has its bottom shaped to fit the
rounded mouth and the lower part of the block, 26, to fit in tho socket part of the
faucet piece in order to insure its being concentric when the outer rim is being cut.
In figure, 3, the parts are shown in the positions they have when the cutting of the
outer rim has just been completed. When this has been done the hydraulic ram, 25,
is raised with the block, 26, and struts or distance pieces, indicated by dotted lines
at, 30, are interposed between the block, 26, and the faucet piece, 19. The central
opening in the stationary block, 29, is made with a contracting taper; and when
downward pressure is again applied the faucet piece, 19, is forced downwards through
the taper opening, and its outer part is thereby made to contract.
The faucet piece, 19, may be fixed to the end of the pipe length by riveting but
when the pipes are not large, say not more than 24 inches in diameter, I prefer to fix
i
it by expanding the end of the pipe length, 31, in the neck of the faucet piece in the
manner indicated in figure, 4, which is an enlarged section. The expanding tools are
applied so as to enlarge the extreme end, 32, of the pipe length, 31, into the inner
end of the socket part of the faucet piece, 19, and also to form an enlargement, 33,
just beyond the end of the neck of the faucet piece in order to lock the parts together.
Whilst expanding the end of the pipe length in the faucet piece the neck of the
latter is confined externally.
The spigot may be formed by fixing a cylindrical ring on the other end of the
pipe length either by riveting or by expanding the end of the pipe length in the ring.
When the end parts for forming the joints for connecting the pipe-lengths together
are to have Hanges; they are made in the form of flanged rings by means of suitably
modified apparatus chown in figures, 5, and 6, on cheet, 3. The plate, 7, figure, 5, is
first ent into a circular disk by means of a stationary steel cutting ring, 40, neting
with-its-inner-edge-in-concert-with the outer edge of a steel cutting ring, 19, fixed
ton block, 45, attached to the rum, 16, of an inverted hydraulic cylinder. When the
outer edge of the disk has been cut, or whilst it is being cut, a central die, 18, is
moved up by the ram, 11, of a lower hydraulic cylinder, and neting in concert with
the inner-edge of the upper entting ring, 10; punches out a circular hole in the
plate: 7, so as to form a flat ring. The flat ring is next transferred to the apparatus

page_text: shown in figure, 6, and is subjected to an operation like that applied to the faucet
ieve (10)-in the apparatus-shown in figure 2 A-die, 23, attached to a block, 21,
which is attached to the rum, 20, of an inverted hydraulic cylinder is made to net on
the fat-ring supported on a stationary-block, 22, which is made with a central
aperture of a diameter the same as that intended to be given to the outside-of the
eylindrical part of the flanged ring. The die, 23, is made to descend and it gradually
forees the inner part of the fut ring down into the central aperture of the block,
until its chape is converted into that of n-Hanged-ring, 31. The bottom of the
block, 1, descends upon the outer-part of the ring and insures-that-1
finished in the proper fut form-for-n-joint fange. When the block, 1, hus been
forced down to its lowest-position-with the die, 23, in the ring, 31, the die, 28, is
loosened, the block, 21, raised, and struts or distance-pieces interposed between them;
-part being
and then the rum, 20. is-moved down again and forces-the-die, 23; completely
through the ring, 34.
The flanged ring, 31, may be fixed-on-the-end of the pipe-length by riveting or-by
expanding the end of the pipe length within it, as shown in section-at-35.
In the various stamping or embossing operations hereinbefore described, the steel
acted upon is heated if required.
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 making of steel pipes with end pieces formed out of plates by stamping
or embossing processes and by apparatus substantially such as is hereinbefore described.
2-The fixing of end pieces on steel pipes by expanding the ends of the pipe
lengths in the end pieces substantially as hereinbefore described.
