PROVISIONAL SPECIFICATION.
Improvements in Machinery for Moulding or Forming the Sockets
of Sanitary Pipes, Chimney Pots, or like Flanged or Socketted
Earthenware.
We ARTHUR SABINE and TIMOTHY SABINE of Swadlincote in the County
of Derby Engineers do hereby declare the nature of this invention to be as
follows:
By this invention we desire to improve machines that are used for the manu-
facture of sanitary pipes and other socketted earthenware and particularly such
portions of the machines as are brought into use in forming the sockets. Our
invention is especially applicable to that type of machine which is described in the
Specification and drawings referred to in Letters Patent granted to us
numbered 1179 and dated 25th March 1878 but may be applied to existing
machines of somewhat different type.
The main object of our present invention is to readily enable a machine such as
mentioned to be so altered or constructed as to permit of sockets of varying
depth being made without the necessity of removing any portion thereof and also
to effect an improvement in the manufacture of square shouldered sockets which
are now much more in demand than sloping shouldered sockets.
In carrying our invention into practice we thread the central spindle of the
machine at a convenient part and mount loosely on the said spindle a second table
having a socket underneath which bears upon a nut internally screwed to run on
the threaded spindle and controlled by a spanner or key. Above this loose table
is mounted the ordinary table of our machine described in Letters Patent No. 1179
of 1878 or that of other machines. In both of these tables we cut radial slots
extending from near the edge to such a distance from the centre as will be
regulated by the diameter of the smallest socket to be made on the machine and in
the slots of the lower table we fix pins or short rods capable of adjustment along
the said slots by means of nuts and washers or other suitable devices, these pins or
rods are of sufficient length to accommodate any desired depth of socket as here-
after described and the ends pass through the slots in the upper table and support
one of a series of rings of varying diameter according to the required diameter of
the socket, the said ring being of metal or other suitable material, and embraced
or encircled by the clam of the top moulding box. Upon the raising or lowering
of the ring by means of the pins or rods operated by the key or spanner before
described a deeper or shallower socket may be formed and by these means our
machine is made specially applicable to the moulding or forming of square
shouldered sockets in the manufacture of which there has hitherto been a difficulty
in getting the clay or other material over the shoulder thus leading to cracked
sockets but by giving say a half turn to the nut on our improved machine and so
raising slightly the ring and compressing the clay upwards into the moulding box
this evil may be overcome whilst this slight turn of the key may be utilized for
throwing the machine out of gear by a suitable arrangement such as by causing it
to engage with or strike against the crank lever as shewn by U in drawings
attached to our Specification No. 1179 of 1878.
The nut may be diminished in thickness on the underside of socket so as to allow
of the key or spanner being worked without coming into contact with the side
columns of the machine.

Improvements in Machinery for Moulding or Forming the Sockets
of Sanitary Pipes, Chimney Pots, or like Flanged or Socketted
Earthenware.
We ARTHUR SABINE and TIMOTHY SABINE of Swadlincote in the County of
Derby, Engineers, 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 :-
By this invention we desire to improve machines that are used for the manu-
facture of sanitary pipes and other socketted earthenware, and particularly such
portions of the machines as are brought into use in forming the sockets, and our
said invention is especially applicable to that type of machine which is described
in the Specification and drawings, referred to in Letters Patent granted to us
numbered 1179 and dated 25th March 1878, but may be applied to existing
machines of somewhat different type, and our main object is to readily enable a
machine such as mentioned to be so altered or constructed as to permit of sockets
of varying depth being made, without the necessity of removing any portion thereof,
and also to effect an improvement in the manufacture of square shouldered sockets,
which are now much more in demand than sloping shouldered sockets.
In describing our method of and means for manufacturing socketted earthenware
we shall refer to the accompanying drawing, whereon
Figure 1 is a sectional elevation of part of an ordinary machine to which our
improvements have been applied, and
Figure 2 is a plan of one of the tables.
In carrying our invention into practice, we thread the central spindle A of the
machine at a convenient part A', and mount loosely on the said spindle a second
table B, having a socket C underneath, which bears upon a nut D, internally
screwed to run on the threaded spindle, and controlled by a spanner or key E.
Above this loose table is mounted the ordinary table F of our machine described
in Letters Patent No. 1179 of 1878 or that of other machines. In both of these
tables we cut radial slots G, extending from near the edge to such a distance from
the centre, as will be regulated by the diameter of the smallest socket to be made
on the machine, and in the slots of the lower table we fix pins or short rods H,
capable of adjustment along the said slots by means of nuts and washers I or other
suitable devices. These pins or rods are of sufficient length to accommodate any
desired depth of socket as hereafter described, and the ends pass through the
slots in the upper table, and support one of a series of rings J of varying diameter
according to the required diameter of the socket, the said ring being of metal or
other suitable material and embraced or encircled by the clam L of the top
moulding box. Upon the raising or lowering of the ring, by means of the pins or
rods operated by the key or spanner before described, a deeper or shallower socket
may be formed, and by these means our machine is made specially applicable to
the moulding or forming of square shouldered sockets, in the manufacture of which
there has hitherto been a difficulty in getting the clay or other material over the
shoulder, thus leading to cracked sockets, but by giving, say, a half turn to the
nut on our improved machine and so raising slightly the ring and compressing
the clay upwards into the moulding box, this evil may be overcome, whilst this
slight turn of the key may be utilized for throwing the machine out of gear by a
suitable arrangement,--for example by causing it to engage with or strike against
the crank lever U (shewn also in drawings attached to our Specification No. 1179
of 1878).
The nut may be diminished in thickness at D¹ on the underside of the socket, so
as to allow of the key or spanner being worked without coming into contact with
the side columns of the machine.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
1. In machines for forming the sockets of sanitary pipes and the like the use of
radially slotted upper and lower tables the latter being capable of being raised or
depressed at will and carrying with it pins capable of being adjusted and fixed at
the required distance from the centre of the table supporting on their extremities
one of a series of rings of various diameters as and for the purposes hereinbefore
described.
2. The method of and means for forming the sockets of sanitary pipes and the
like substantially as herein before described and as illustrated by the accompanying
drawings.
