PROVISIONAL SPECIFICATION left by the said Thomas Hassall Adcock and
John Hassall at the Office of the Commissioners of Patents on the 5th August
1879.
THOMAS HASSALL ADCOCK and JOHN HASSALL, of Woodville, in the County
of Leicester. "IMPROVED APPARATUS FOR MOULDING SOCKETED PIPES AND OTHER
SOCKETED OR FLANGED EARTHENWARE ARTICLES."
The object of this Invention is to construct a simple apparatus for moulding the
sockets or flanges on pipes and other articles, which can be readily adapted to the
machines at present in use for making such articles.
In carrying out our Invention, in addition to the ordinary plain die attached to
the barrel of the pug mill, we adapt to the rising and falling table of the pipe
moulding machine a special die to form the socket. This die consists of a short
open cylinder firmly secured to a base plate which is hinged to the table. The top
of this cylinder forms the face of the socket, and its diameter corresponds to the
diameter of the socket required. Inside this cylinder is fitted a core or plug to form
the inside of the socket and shoulder of the pipe, while outside is placed a ring, which
is secured to the core by screws passing through slots in the cylinder, and serves to
form the outside of the socket. The outer shoulder of the socket is formed by the
plain die, the inner edge of which is bevilled off for the purpose.
A handle, which projects through inclined slots formed in opposite sides of
the cylinder, is pivotted to the underside of the core, and by turning this handle
to the right or left the core with the ring is raised from or brought down flush with
the top of the cylinder.

page_text: The rising and falling table, which is mounted in the usual way, is provided with
a stop motion, whereby it may be retained in an elevated position during the
formation of the socket.
The working of the apparatus is as follows:-
The core with the ring is raised by turning the handle, and the table is then
elevated so as to bring the face of the core and ring against the under side of the
plain or fixed die, and the stop arrangement is brought into action. The clay is
then worked down through the plain die into the socket die, and when this is filled,
which can be ascertained by the clay issuing from pin holes made in the ring, the
stop is withdrawn and the table is allowed to descend gradually with its increasing
load until the required length of pipe is formed. A cutting-off wire is then brought
into action to cut off the length of pipe.
The core and the ring are then drawn down by turning the handle in the reverse
direction, and the hinged mould is then tipped over, and the formed length of pipe
is received on a cradle or other suitable receptacle for conveyance to the drying
ground or kiln.
The rising and falling of the table may be caused by weights attached by chains
to pass over pulleys to the table, or in any other convenient manner.

THOMAS HASSALL ADCOCK and JOHN HASSALL, both of Woodville, in the County
of Leicester. "IMPROVED APPARATUS FOR MOULDING SOCKETED PIPES AND
OTHER SOCKETED OR FLANGED EARTHENWARE ARTICLES."
The object of this Invention is to construct a simple apparatus for moulding the
sockets or flanges on pipes and other articles, such for example as chimney-pots,
that can be readily adapted to the machines at present in use for making such
articles.
In carrying out our Invention, in addition to the ordinary pipe die attached to
the barrel of the pug mill, we adapt to the rising and falling table of the pipe
moulding machine a special die to form the socket.
In the accompanying Drawing Figures 1 and 2 are respectively a front and side
elevation of a pipe moulding apparatus, with the socket mould connected therewith.
Fig. 3 is a side elevation of part of the moulding apparatus, with the socket mould
in its lowest position; and Fig. 4 is a detailed view in section of the special die
for forming the socket.
A is the cylinder containing the rotating propeller; B is a pipe die fitted to this
cylinder, and through which the clay to form the pipe is forced as usual; C is a
rising and falling table, which receives the moulded pipe as it issues from the pipe
die B in the ordinary manner, and to it is fitted the special die D. This table C is
provided, as usual, with guides, which slide on rods E, E, connected at top with a
cross head F attached to the cylinder A, and at bottom to a bed plate G. The
table C is also provided with a central rod H, which projects through the plate G
into a guide socket G₁ bolted to the underside of the plate G, and which in
combination with a stop-motion, to be hereafter described, holds the table with the
die thereon against the pipe die B while the socket or the flange is being
formed.
The rising of this table is caused by weights attached by chains or ropes to the
table C, and which pass over pulleys, as shewn in the Drawing, or the upward
movement of the table may be effected in any other convenient manner.
The special die D, in which the socket of the pipe is moulded, is formed of three
parts, vizt., a short open cylinder a firmly secured to a base plate b, which is hinged
to the table C, as shewn at Fig. 4. The upper edge of this cylinder forms the lip
of the socket (see Fig. 4), and its diameter corresponds to the diameter of the socket
required. Inside this cylinder is fitted a moveable core or plug c for forming the
inside of the socket and shoulder of the pipe. This core is connected to a sleeve d
(surrounding the cylinder a) by means of screws e, e, passing through vertical slots
in the cylinder a. This sleeve d has an internal diameter equal to the external
diameter of the socket, and forms the external wall of the socket mould. The outer
face of the shoulder of the socket is formed by the pipe die B, the inner edge of
which is bevilled off for the purpose.
Pivotted to the under side of the core c is a handle f, which projects through
inclined slots g, g, formed in opposite sides of the cylinder a. By turning this
handle to the right or left the core c with the sleeve d is raised above or brought
down flush with the top of the cylinder a.
A stop motion is provided to maintain the table C in its highest position ab
which the socket die D will bear against the face of the pipe die B, and the parts
will be in position for the moulding of the socket. This stop motion consists of a
sliding bolt h pivotted to an arm i, keyed on a rock-shaft k suitably mounted in
bracket-bearings fixed to the under side of the bed plate G. This rock shaft k is
actuated by a lever l. The sliding bolt h enters a hole formed in the socket guide G¹,

page_text: and projects under the end of the central rod H when the table C is at its highest
position, see Fig. 2.
The working of the apparatus is as follows:-The core c with the sleeve dis
raised by turning the handle f into the upper part of the inclined slot f, as shewn
at Fig. 1, and the table C is then elevated so as to bring the face of the core c and
sleeve d against the under side of the pipe or fixed die B, and the stop arrangement
is then brought into action, as shewn at Fig. 2. The clay is then worked down
through the pipe die B into the socket die D, and when this is filled, which can be
ascertained by the clay issuing from pin holes made in the sleeve d, the stop h is
withdrawn by pulling the lever into the position shewn at Fig. 3, and the counter-
weighted table C is allowed to descend gradually with its increasing load of pipe.
When the required length of pipe is formed a cutting off wire is used to cut off
that length of pipe, the action of the clay propeller being at that time suspended.
The table then completes its descent, and the socket die D with its pipe is ready to
be tipped over, as indicated at Fig. 4, for the purpose of releasing it from the die D.
To facilitate this the core c and the sleeve d are drawn back by reversing the
motion of the handle fin its inclined slots, that is to say, to the lowest part of the
slot g. The formed length of pipe is received onto a cradle or other suitable recep-
tacle for conveyance to the drying ground or kilo.
It will be obvious that for forming flanges on pipes when such are required the
form of the socket die D must be modified.
Having now set forth the nature of our Invention of "Improved Apparatus for
Moulding Socketed Pipes and other Socketed or Flanged Earthenware Articles," and
explained the manner of carrying the same into effect, we wish it to be understood
that under the above in part recited Letters Patent we claim,-
First. The arrangement of apparatus, as herein shewn and described, for moulding
pipes and other earthenware articles with sockets or flanges.
Second. The construction of the mould for forming the sockets or flanges on pipes
or other earthenware articles, as herein shewn and described.
In witness whereof, we, the said Thomas Hassall Adcock and John Hassall,
have hereunto set our hands and seals, the Second day of February, in
the year of our Lord One thousand eight hundred and eighty.
