PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Making Earthenware Socket Pipes.
I ERNEST SMITH of Canal Potteries Old Kent Road in the County of Surrey
Manufacturer do hereby declare the nature of this invention to be as follows:-
The objects of this invention are to expedite the production of socketted earthen-
ware pipes and to form a better socket than is attainable by the apparatus hitherto in
use.
-
According to this invention I form the female die of such a length that when a
newly made pipe is cut off there is sufficient clay or plastic material left in the die to
form the socket of the next pipe such socket being formed by the male die to the
bottom of which pressure is applied by any suitable means.
One way of carrying out this invention is by fitting a female die which may be in
one piece instead of in halves as heretofore to an ordinary steam or other pipe
machine such die being of such a length as when the pipe last made is cut off there is
sufficient material left in the die to form the socket of the next pipe.
The bottom or male die rests on a table attached to a rod passing through the
piston rod of a steam or other cylinder the two rods being connected to or disengaged
from each other by means of a suitable locking device.
To form a pipe the table carrying the male or bottom die is secured to the piston
rod of the bottom cylinder and pressure applied when the said die rises and expands
the clay or other material left in the upper or female die till it fills the same and thus
forms the socket, pressure is then applied to the upper cylinder and the material in
the hopper is forced through the die and forms the pipe.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Making Earthenware Socket Pipes.
I ERNEST SMITH of Canal Potteries Old Kent Road in the County of Surrey
Manufacturer 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 :-
The objects of this invention are to expedite the production of socketted earthen-
ware pipes and to form a better socket than is attainable by the apparatus hitherto in
use.
According to this invention I form the female die of such a length that when a
newly made pipe is cut off there is sufficient clay or plastic material left in the die to
form the socket of the next pipe such socket being formed by the male die to the
bottom of which pressure is applied by any suitable means.
One way of carrying out this invention is by fitting a female die which may be in
one piece instead of in halves as heretofore to an ordinary steam or other pipe machine
such die being of such a length as when the pipe last made is cut off there is
sufficient material left in the die to form the socket of the next pipe.
The bottom or male die rests on a table attached to a rod passing through the
piston rod of a steam or other cylinder the two rods being connected to or disengaged
from each other by means of a suitable locking device.
To form a pipe the table carrying the male or bottom die is secured to the piston
rod of the bottom cylinder and pressure applied when the said die rises and expands
-

page_text: the clay or other material left in the upper or female die till it fills the same and thus
forms the socket, pressure is then applied to the clay cylinder and the material is
forced through the die and forms the pipe.
And in order that my said invention may be the better understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in which
Figure 1 represents section through the clay cylinder of an earthenware pipe making
machine with the dies constructed according to this invention.
Figures 2 and 3 are details hereafter referred to, same letters denote same parts in
all the Figures.
a is the clay cylinder b. the clay c. the portion of clay left in female die d. which
portion of clay forms the socket of the next pipe, e. bell or cone, to form interior of
pipe, f. rod to hold same in place g. male die attached to rising and falling table h.
ii cords or chains passing over pulleys jj to which cords are attached the balance
weights k. k. to balance or partly balance the weight of the tahle h. and die g.
attached to table which rod passes through piston rod n. of a steam or hydraulic
cylinder (not shewn in drawing) this rod m. has a portion o. of 'smaller diameter than
the remainder of the rod as shewn at Figure 3.
m rod
1 provide also a horse shoe shaped piece p. shewn in plan at Figure 2. fitting over
the portion o. of the rod m. When the piece p. is in the position shewn in Figure 1.
the pressure of the rod n. is transmitted through the piece p. and rod m. to the
table h.
To form a pipe (supposing one pipe to have been already made and cut off) the
table h. carrying the male die g. is secured to the piston rod n. of the bottom cylinder
by means of the piece p. as explained above and pressure applied when the table h.
and die g. rise and the die g. expands the clay or other material c. left in the
upper die d. till it fills the same and forms the socket pressure is then applied to the
clay or other material b. in the clay cylinder a and the said material is forced through
the die d. and forms the pipe, the table h and die g. moving downwards as the pipe
comes through the die d.
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
I. In an apparatus for making earthenware socket pipes the improved die d. as and
for the purpose specified.
II. In an apparatus for making earthenware socket pipes the combination of the
improved die d. with a means for putting pressure on the underside of the rising and
falling table h. and a means for securing the said table to the source of pressure or
releasing it therefrom substantially as described and shewn.
