Improvements in or relating to Machines for Making Faucet or
Socket Pipes of Clay or such like.
I, JAMES GUILD, of the Firm of George Guild and Son, Drumkilbo Brick and Tile
Works, Meigle, in the County of Perth, Brick and Tile Manufacturer, do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to make faucet or socket pipes in a simple manner,
the complete pipe with faucet being made without any break in the continuity of the
material forming said pipe. The material of which the pipes are made, may be of clay
or such like plastic matter.
In carrying out my invention I employ a cylinder into which the clay is placed, and
force it to flow through a suitable orifice, by means of a plunger. The orifice in the
cylinder has a central plug, though somewhat smaller; the clear space between the
orifice in the cylinder and the plug allowing the clay to pass, and thus forming
the pipe, as it is forced through. By cutting the pipe into suitable lengths plain
cylinders are produced.
When I wish to make a pipe with a faucet or socket, I fasten to the end of the
cylinder my improved attachment, consisting of an outer ring for forming the
external portion, and an inner ring or die for the internal portion of the faucet.
The outer ring is made of wood or other suitable material, and is hooped with an
iron ring to strengthen it. Said outer ring is made internally of the shape of the
external portion of the faucet on the pipe, and its surface is covered with a textile
fabric known as "moleskin" or with chamois leather. The surface of the ring against
which the "moleskin" is laid is provided with a number of circumferential grooves
and has other grooves cut at right angles, to form communication between each other.
A pipe for water or steam leads from the exterior to these grooves for the purpose of
lubricating the "moleskin" and it also may allow the pressure of the atmosphere to
act upon the said "moleskin." The outer ring, which is bolted to the end of the
cylinder, is kept from bearing directly against same by means of distance pieces,
for the purpose of permitting the pressure of the atmosphere to act upon the clay,
as it passes out of the cylinder. Other holes are made through the ring for a similar
purpose.
The inner ring or die is fastened to the central plug of the cylinder orifice, in such
a fashion that it can be easily removed after each faucet has been formed. The part
of the die which comes against the central plug fits closely to same when in position
and has a cavity at its centre, communicating with the atmosphere in a suitable
manner. The exterior surface of the die is formed in the shape of the internal portion
of the faucet, and is covered with "moleskin" or chamois leather and its surface has
circumferential and other grooves similar to those on the outer ring.

Improvements in or relating to Machines for Making Faucet or
Socket Pipes of Clay or such like.
I, JAMES GUILD, of the Firm of George Guild and Son, Drumkilbo Brick and
Tile Works, Meigle, in the County of Perth, Brick and Tile 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 object of my invention is to make faucet or socket pipes in a simple manner;

page_text: :
the complete pipe with faucet being made without any break in the continuity of the
material forming said pipe. The material of which the pipes are made, may be clay
or such like plastic matter.
The accompanying sheets of explanatory drawings illustrate the method of carrying
out my invention. Figure 1. (Sheet No. 1.) represents a section through the cylinder
of the machine which is generally used for the manufacture of clay pipes, and
Figures 2. 3. and 4. (Sheet No. 2.) a section at C. C., and a part section of the bottom
of the cylinder 5. a section at A. A. and a view looking on B. B. respectively, of my
apparatus.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
.
In carrying out my invention, I employ a cylinder 5. into which the clay 6. is
placed, and force it to flow through a suitable orifice 7. by means of a plunger 8.
actuated by the non-rotating screw 9. and the nut 10. said nut being keyed to and
rotating with the wheel 11. The wheel 11. is made to rotate by suitable gearing, in
either direction, and thus the plunger is raised or depressed as may be desired. The
orifice in the cylinder 5. has a central plug 12. though somewhat smaller; the clear
space 7. allowing the clay to pass, and thus forming the pipe as it is forced through. By
cutting the pipe into suitable lengths plain cylinders are produced. The foregoing is
a description of the ordinary machine used for the manufacture of plain pipes and to
which my apparatus may be attached, when I wish to manufacture faucet or socket
pipes.
When I wish to make a pipe with a faucet or socket, I fasten by means of the
bolts 13. to the end of the cylinder, my improved attachment consisting of an outer
ring 14. for forming the external portion, and an inner ring or die 15. for the internal
portion of the faucet.
The outer ring 14. may be made of wood-although I find cast iron to be the
preferable material-and if made of wood is hooped with an iron ring 16. to
strengthen it. Said outer ring 14. is made internally of the shape of the external
portion of the faucet on the pipe, and its surface is covered with a textile fabric 17.
known as "moleskin" or with chamois leather. The surface of the ring against
which the "moleskin" is laid is provided with a number of circumferential
grooves 18. and has other grooves 19. cut at right angles, to form communication
Between each other. Channels 20. are also provided for the same purpose. A
pipe 21. for water or steam leads from the exterior to these grooves for the purpose
of lubricating the "moleskin," and it also may allow the pressure of the atmosphere
to act upon the said "moleskin." The "moleskin" is fastened to the ring at its upper
and lower surfaces only, by means of the nails 22. The outer ring 14, which is bolted
to the bottom of the pipe die 12., is kept from bearing directly against same by means
of distance pieces 23., for the purpose of permitting the pressure of the atmosphere
to act upon the clay, as it passes out of the cylinder. The inner ring or die 15. is
fastened to the central plug 12. of, the cylinder orifice, in such a fashion that it can
be easily removed after each faucet has been formed. The appliance which I
_prefer to employ consists of the stud 24. fixed to the central plug 12. and the
nut 25. securely held in the die 15. so that by turning round the die about the
stud, it can be made to bear against the central plug. The part of the die which
comes against the central plug fits closely to same when in position and has a
cavity 26. at its centre, communicating with the atmosphere by means of the
channels 27. The exterior surface of the die is formed in the shape of the internal
portion of the faucet, and is covered with "moleskin" or chamois leather and its
surface has circumferential and other grooves similar to those on the outer ring.
When manufacturing spigot or faucet pipes 1 fill the cylinder 5. with clay of the
proper plasticity in the usual manner and fix my attachment to the bottom of the
central plug in the cylinder. As the wheel 11. is made to rotate in the proper direc-
tion carrying with it the nut 10., the screw 9. and the piston S. are forced down,
..sending the clay through the orifice 7. until it appears at the bottom, thus forming
the complete faucet or socket. The die 15. is now unscrewed and laid aside and by

page_text: again forcing the piston to press out more clay, the plain portion of the pipe is
formed and then cut to a suitable length.
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) In machines for making faucet or socket pipes, the use of the attachment con-
structed and arranged substantially as and for the purposes herein set forth, together
with any mere modification or modifications thereof.
(2) In machines for making faucet or socket pipes, the method and means
whereby water, steam, or air, is admitted to the back of the "moleskin" or chamois
leather as described.
(3) In machines for making faucet or socket pipes, the use of the distance
pieces 23. whereby the pressure of the atmosphere is admitted to the clay as it passes
out of the cylinder and into my attachment, as herein before described.
(4) In apparatus for making faucet or socket pipes the use of the stud 24. and the
nut 25. for holding the die 15. in position.
