PROVISIONAL SPECIFICATION.
Improvements in and connected with Plastic Pipe Making
Machinery.
I, AMELIA NOEL, of 2 Richards Terrace, Cardiff, South Wales, do hereby
declare the nature of this invention to be as follows:--
This invention relates to certain improvements connected with plastic pipe
making machinery, the object being to arrange a series of tables on a post common
to all of them, so that as each pipe is made, the table carrying frame can be turned
clear, and a fresh table be brought into position for the make of a fresh pipe and so
on according to the number of tables fitted to the table frame.
To enable this to be effected, I joint the resistance pressure rod, so that it can be
swung or slewed clear of the descending rod of each table when the shift is
required.
With three tables, one would be at work producing a pipe under machine, another
would be down awaiting the taking off of the pipe last made, and the third table
raised to the die level ready to place under the die, the arrangement would be
applicable to ordinary machines, or those having means for pressing up the sockets,
and each following table could be made to rotate on its rod, thus forming a spinning
head for the pipes to be fettled before their removal. The pipes as they come from
machine are placed on conical stands of wood, iron, or clay ware, so that the pipes
dry rapidly, safely, and do not lose their cylindrical form.

COMPLETE SPECIFICATION.
Improvements in and connected with Plastic Pipe Making
Machinery.
I, AMELIA NOEL, of 2 Richards Terrace, Cardiff, South Wales, 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 :-
This invention relates to certain improvements connected with plastic pipe
making machinery the object being to arrange a series of tables on a post common
to all of them, so that as each pipe is made, the table carrying frame can be turned.
clear, and a fresh table be brought into position for the make of a fresh pipe, and
so on, according to the number of tables fitted to the table frame.
My invention is clearly shown in the annexed drawings.
Figure 1 is an elevation, and Figure 2 a plan of a drain pipe forming machine
with three tables and their appurtenances on swing arms carried by a revolving
sleeve on a post.
Figures 3 and 4 are elevation and plan of a socket former device affixable to the
pillars of the machine.
Figure 5 indicates a ring with inner conical, or chamfered surface with a pipe
resting on it for rapid drying and for preserving its shape.
Referring to Figures 1 and 2, A, B, are two pillars supporting the die
cylinder C. The pillar B is provided with a collar D for the sleeve E to rest

with hollow ends I, I, I, for rods J, J, J", to be guided up and down.
Each arm has a pulley K and a chain or rope L connected to a lug M on the
rods J, J, J, with tables R, R, R", at their upper ends, and to counterbalance
weights N, N1, N to return the rods after the pipe last made has been swung
round, as indicated at A', and removed the rod J by a swing action then taking its
position under the die cylinder C. P is a bar capable of serving as a rest, or
resistance to the downward movement of the rods while the clay is being first
pressed through the nozzle Q of the cylinder C. Then the rest P is knocked to
one side, and the pipe continues to be made while the table and rod are descending
under the pressure of clay from the cylinder C.
The socket former consists of two half rings T, T, pivoted at U, U, on a
bridge V, the pivot bosses of the rings being provided with quadrant pinions W, W,
for opening and closing both half rings simultaneously by movement of the
handle Y.
These half rings only shape the exterior of the sockets, the interior being shaped
by moulds on the tables.
Each pipe, (socketed or other) as removed from the tables R is reversed, and its
end set in the chamfered recess of the ring Z, as at Figure 5, to dry, a free current
of air passing through the ring and pipe facilitates the drying, and from an equal
seat being obtained on the ring, the shape of the pipe is preserved.
The tables may be rigid on the rods J, J, J", or be loose for spinning to enable
the pipe to be "fettled" before it is removed from the table.
may dispense with the knock lever P and use a piston of any kind.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In a drain and like pipe making machine the employment of a swing sleeve E
with arms F, F, F", and sliding rods J, J', J", for the rapid production of pipes
thereon, or therefrom, whether the socket forming die be part of the outlet Q of
the cylinder, or as an attachment to the machine, as hereinbefore described and
substantially as represented in the annexed drawings.
