An Improved Socket Ring or Die for the Mouth of a Pipe Machine.
by means of which Pipes may be Bent to any Radius.
I, JOHN HALL, of the Firm of Hall and Boardman Limited, of Swadlincote,
near Burton-on-Trent, in the County of Derby, Sanitary Pipe Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable curved earthenware pipes and fittings
such as bends and springs to be made in the ordinary pipe machine instead of
being made in moulds in the usual way.
Now according to this invention I make the socket ring or die which shapes the
outside of the socket end of the pipes in two parts horizontally one part being
secured to the machine and the other to the rising and falling table.
When making a curved pipe bend or spring the table is held up under the
portion of the socket ring or die which is attached to the machine so that the
two portions of the socket ring or die are brought together and the socket formed,
the table is then released and begins to fall taking with it the portion of the
socket ring or die which is attached thereto thus permitting the pipe to be at
once bent to the required shape instead of having to be forced out clear of the
socket ring or die as heretofore.
By this means sharp bends may be made direct from the machine and of any
diameter which prior to this invention has been impossible.

An Improved Socket Ring or Die for the Mouth of a Pipe Machine,
by means of which Pipes may be Bent to any Radius.
I, JOHN HALL, of the Firm of Hall and Boardman Limited, of Swadlincote,
in the County of Derby, Colliery Owner, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
The object of this invention is to enable curved earthenware pipes and fittings
such as bends and springs to be made in the ordinary pipe making machine instead
of being made in moulds in the usual way.

page_text: Now according to this invention I make the socket ring or die which shapes the
outside of the socket end of the pipes in two parts horizontally one part being
secured to the machine and the other part to the rising and falling table.
When making a curved pipe bend or spring the table is held up under the
portion of the socket ring which is attached to the machine so that the two portions
of the socket ring are brought together and the socket formed.
The table is then released and begins to fall taking away with it the portion of
the socket ring which is attached thereto thus allowing the pipe to be at once
bent to the required shape instead of the pipe having to be forced out clear of the
socket ring as heretofore.
By this arrangement of socket ring sharp bends can be made direct from the
machine up to any diameter which was impossible prior to this invention.
And in order that my said invention may be fully understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in
which
Fig. 1 is side elevation of my improved socket ring or die constructed according
to this invention.
Fig. 2 is section of same.
Fig. 3 is plan of same.
Fig. 4 shews same in use but only such parts of the machine as are absolutely
essential are shewn.
The same letters denote the same parts in all the figs.
The ring which forms the outside of the socket is made in two portions the
upper portion being attached to the mouth a of the machine and the lower portion
resting on or attached to the flange b of the die c which forms the inside of the
socket.
The flange bis hinged at d to the rising and falling table e is a handle for
tipning over the finished pipes when straight lengths are being made.
It must be understood that the parts marked a bede are old and well known
and therefore form no part of this invention.
The upper portion f of my improved socket ring or die is made in one piece
of metal and shapes a portion of the shoulder and half the circumference of the
socket of the pipe the remaining portion g¹ of the shoulder being formed in
the mouth of the machine.
hi are lugs by means of which the portion f is secured to the mouth a of the 3
machine.
jjare wrought iron or steel bands to form a guide for the lower portion of the
ring and also to prevent the two portions of the ring from separating while the
socket is being formed.
The lower portion of the socket ring is preferably formed of two pieces bolted 4
together viz. a plate which encircles the die c and which shapes the end of the
socket and the semicircular flanged piece 7 which shapes the outside of the socket
or the plate and piece may be in one casting.
The plate is provided with suitable feet or legs m which rest on the plate b.
If the socket is required to be shallower than shewn in the Fig. a loose ring 4
may be placed on the plate k.
n is a curved piece of metal fitting the outside of the portion f when the socket
ring or die is in the position shewn by Figs. 1 and 2 and acts as a guide and also
surves to prevent the two portions from spreading.
The piece is bolted or rivetted to the plate k.
When making a curved pipe the table is brought up so that the two portions of
the socket ring are in contact and form a complete die and is held in this position
until the socket is shaped the table is then released and falls carrying with it
the lower portion of the socket. ring and the die which shapes the inside of the
socket.
The workman then grasps the pipe and bends it to any required curve as it
issues from the pipe die.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
1. Socket rings for the mouths of pipe machines consisting of two portions the
upper portion which is fixed to the mouth of the machine shaping a portion of the
shoulder and one half of the outside of the socket the other portion which is sup-
ported by the rising and falling table shaping the other half of the outside of the
socket substantially as and for the purpose specified.
2. Socket rings or dies for the mouths of pipe machines constructed as shewn
by the accompanying drawings.
