Improvements in Machines for Making Sanitary Pipes.
WILLIAM INGHAM of Stainforth Horsforth near Leeds Sanitary Pipe
Manufacturer and BENJAMIN LANGTON of 1 Barras Garth Road Wortley near
Leeds Mechanic do hereby declare the nature of this invention to be as follows:-
The improvements consist,-
1st. In an adjustable stock die which allows any size die to be fixed into the
machine perfectly true with the centre thus saving all the time wasted in setting
according to old system, and causing the pipes to be perfectly true and of one
uniform thickness throughout, which has been impossible under the old methods.
2nd. In a metal rim fixed on springs to die for socketting pipes. This is used
instead of the hinged slides and other methods at present adopted, and not only
saves considerable time in making pipes, but turns out a cleaner and better socket.
The object of the rim being suspended on springs is to allow air to enter freely all
round and prevent the suction caused by the old method, as also the clay socket
adhering to the dies.
3rd. The addition of grooves in the die face the object of this is that the grooves
fill with air and cause the socket to be released more easily.
4th. The additon of two bars fixed to or cast or moulded on each side of the ram
of the balance-table; these work in corresponding grooves or slots in the
foundation-plate. There are handles fixed to the top of the ram, which when the
rising table is in its position for pressing socket are used for turning the ram round
to allow the ends of the bars or rods to rest on the solid part of the foundation-
plate, which resists all pressure whilst the socket is being made. The table is
Swivelled or turned loose on the top of the ram, so that when the ram is turned
round or locked the table remains stationary.
5th. The addition of an automatic or foot brake on the bottom of the ram is to
prevent the table and ram going down too suddenly whilst the pipe is being made.
6th. The addition of two pillars with bolts passing through them bolted to each
side of stock die and bottom of each end of foundation-plate, which binds machine
and foundation firmly together.

Improvements in machines for making Danivary
WILLIAM INGHAM of Stainforth, Horsforth near Leeds Sanitary Pipe
Manufacturer and BENJAMIN LANGTON of 1, Barras Garth Road, Wortley near
Leeds Mechanic, do hereby declare the nature of this invention and in what
inanner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
In order to fully explain my said invention I have hereunto annexed a drawing

page_text: of the machine partly in section to show the necessary details. Letters of reference
to this Spcification refer to corresponding ones on the said drawing.
A, is the clay cylinder, B. is a shaft or rod fixed axially central in the
cylinder A., which carries the centre core or drum-head F. secured to it by means
of a nut and washer. The centre cores are of varying sizes and determine the
inside diameter of the pipe required. C. is the die-holder or adjustable stock-die
in which the size-die G. is held by means of bolts E. axially central with the
centre core F. thus insuring an even thickness of pipe. The size-dies G. are of
varying sizes and determine the outside diameter of the pipe required. Being only
about one-fourth the weight of those generally used they can be easily adjusted by
hand, instead of having to be blocked up in order to bolt them into position, thereby
saving much time in setting. D. are the bolts securing the cylinder A. to the
die-holder C.; K. is the open-joint between the size-die G. and socketting ring H.,
which is secured to it by studs and helical compression springs J. The socketing
rings H. are of varying sizes and determine the outside diameter and width of the
socket on the pipe required. I. is the core-box fixed on the table M., which is
mounted on the ram N. having a vertical motion in the block R. and guide I.
beneath it on the same axial line as the size die G., die-holder C., socketting ring H.
and centre core F. above. The core-boxes are of varying sizes and determine the
inside diameter and depth of the socket on the pipe required. L. are pillars
bolted to the ends of the foundation plate P. at the bottom and to the die-holder C.
at the top. O. are the two keys or bars fixed to or cast on each side of the
ram N. which work in corresponding keyways or grooves in block R. Q. are
handles attached to top of ram N. and S. are adjustable balance-weights, parts of
which are made detachable to compensate for the varying weights of the different
core-boxes I.; U. is a foot-plate which operates a lever-brake V. on the ram N.
This brake is formed of 2 concave surfaces of wood which are pressed tightly upon
the surface of the ram N by means of helical springs W when in operation and
are released on pressure being applied to the foot-plate U., which presses a
wedge between them and thereby removes the friction. The action of the machine
is as follows:--The ram N. is raised until the core-box I. is in the position shewn
by the dotted lines "i" the bottom of the keys O. is then just clear of the keyways
and by giving the handle Q. a quarter turn the keys O. butt against and rest on
the block R. The table M. swivels loose on the top of the ram N. so that
when the ram N. is turned round the table M. remains stationary. The clay is now
pressed in from the cylinder A. and forms the socket of the pipe. The handles are
then turned round until the keys O. are again opposite the keyways in the block R.,
and the pressing of the pipe continues until it is of the required length, the
ram N. &c. being balanced by the counter-weights S. slowly descending. The
air-grooves shewn on the face of the size-die G. fill with air and allow
the socket to be released more easily. The socketting ring H. being fixed on
springs J. allows air to enter freely at joint K. and prevents the suction caused by
the old method, thereby insuring a cleaner and better socket, and, at the same time,
making 50% more pipes. The descent of the ram can be instantly checked by
the operator releasing the pressure of his foot from the foot-plate U. of the
automatic lever-brake V., and the same man can actuate the lever or other means
used to control the supply of clay from the cylinder without other assistance to
steady down the pipe to the requisite length.
Having thus fully described the nature and object of this my said invention I
would have it understood that the parts which I claim to be new are:-
1. The adjustable stock-die C. into which the various size-dies G. are made
inter-changeable ;
2. The socketting ring H. on spring and studs J.;
3. The addition of grooves on the face of the size-dies G.;
4. The keys or bars O. on the ram N. working in corresponding keyways or

page_text: 5. The addition of the foot-brake V.;
6. The addition of the two pillars L. binding the machine together;
7. The combination of the various parts as herein fully described and for the
purpose herein set forth.
