PROVISIONAL SPECIFICATION,
Machine for Moulding Spigot and Socket Pipes, Flange Pipes, and
the like.
FRED HERBERT, Moseley House, Birtley, Durham, Ironworks Manager, do
hereby declare the nature of this invention to be as follows:-
one
The moulding machine may consist of a sliding piston, ram, guide, upon
which the pattern of the pipe to be moulded is attached, the pipe pattern
may be of the exact shape of the pipe to be made, and
piece, (with the usual allowances for contraction) or it may be made in several
pieces, and the spigot, the socket portions, or the flanges, may be made seperately,
and it may be that each portion of the pattern, is worked by a seperate piston,
ram, or guide portion, and the socket & spigot, or flange portions, may be made
to slide over or upon, any other portion of the pattern, so that each portion can
be moved simultaneously with any or every other portion, or may be moved or
worked independently of each other. The pipe pattern will be made with a
conical, or other suitable shaped portion attached to it, or it may be that the
cone is seperate and have a seperate motion from the pattern, the object of the
conical part of the pattern, is that it may be forced through the moulding box
containing the sand or other material in which the pipe is to be moulded, so that
the passage of this cone or conical portion of the pattern or ram, compresses the
sand, against the walls of the moulding box or its equivalent, and thus com-
presses or rams the body of the mould in which the pipe is to be cast, and in like
manner the sockets, spigots, or flanges of the pipe, may be formed by forcing the
spigot, socket, or flange patterns, or portions of the pattern into the moulding sand
& box, so that any or every part of the pipe mould, may be formed by forcing
the pattern or patterns into the sand or the moulding box containing the sand,
and thus all or any portion of the mould can be moulded by the machine, and
the reverse motion of the machine could be made to withdraw the pattern, or
patterns. It is probable that for some sizes of pipes and moulding boxes it
would be necessary to measure or guage the amount of sand put into the mould-
ing box, so that the cone or pattern would compress it to the proper density, this
will probably be accomplished, by placing a projecting piece on the cone or
pattern, or by a seperate tube or shaft, which may extend through or partly
through the moulding box, in such a manner that the sand contained between the
exterior surface of this tube or shaft, and the interior surface of the moulding
box would be the proper quantity of sand required for the mould. This pro-
jecting portion of the pattern may be formed by a rod or ram passing through
the pipe pattern or cone, or either of them, or it may be carried on or in front
of the cone or pattern, or be seperately placed in the box or upon the cone, by
hand or any suitable contrivance. It may be arranged so that when the cone
has been rammed through the sand, the pattern of a spigot, socket, or flange
may then be attached to the cone, pattern, or ram so that the reverse motion of
the ram or its equivalent would mould the spigot, socket, or flange, at the top or
further end of the mould, or this portion of the mould may be formed by a seperate

page_text: pattern piece & ram.
This machine may be made to travel to the moulding
boxes, or it may be fixed and the moulding boxes be moveable, and the machine
may be worked by steam, hydraulic, compressed air, or any other suitable power:
as and for the purpose above described.
Machine for Moulding Spigot and Socket Pipes, Flange Pipes, and
the like.
FRED HERBERT, Moseley House, Birtley, Durham, Ironworks Manager, 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 follow-
ing statement:-
This invention relates to the manufacture of spigot and socket pipes, flange
pipes, and the like by an improved method of forcing a taper, die, or cone, or
conical or tapershaped pattern, through or into the moulding material, thus
forming a mould by causing the die or pattern to compress the sand and form
the mould in such a manner that every portion or portions of the pipe to be made
can be moulded by the machine. And in order to more fully describe the manner
in which this is to be performed, I have annexed hereto a sheet of drawings
and at Fig. 1 show at A a moulding box, B is the moulding sand or other suit-
able material C is a die or cone which is placed on the end of a ram D, which
ram is shown working through and within another ram E, upon the ram E
is mounted a socket patern F. At G is a shaft, tube, or projecting piece mounted
upon and in front of the die or cone C. Both the rams D and E work within a
ram cylinder H, or it may be that the rams D and E are actuated by seperate
and independent cylinders, I is a carriage upon which the ram cylinder or
cylinders are mounted, and when necessary this carriage together with the rams,
cylinders and cones may be moved upon the wheels and axles from one moulding
box to another as may be required, or slides or the like may be used for this
purpose. The method of working the machine illustrated by Fig. 1 and described
as above is as follows. Assuming that the rams D and E were in their lowest
positions, then the cone shaped die C, and socket pattern F would be below and
quite clear of the moulding box A. The space between the inner walls of the
moulding box A and the outer surface of the measuring tube, shaft, rod, or its
equivalent, is now filled with band or other moulding material, and the ram D,
together with the cone C is caused to pass within and through the moulding box
and the sand contained within it, and the passage of this cone shaped pattern
compresses the sand against the inner surfaces of the moulding box and thus
formis the body of the mould, and in like manner when the ram E and the
socket pattern Fare moved forward towards the box, the sand surrounding the
socket pattern is still further compressed, and the socket portion of the mould
is formed. Fig. 2 illustrates a method of making spigot and socket pipes, with
the socket F moulded at the upper end of the mould instead of at the lower
end of the mould as shown at Fig. 1. In this case (Fig. 2) the spigot pattern K
is formed by an enlargement of the lower portion of the ram D, or may be a
sleeve sliding on the ram D and worked by a seperate cylinder or ram exactly in
the same manner as the socket pattern F in Fig. 1 is worked, but in Fig. 2 the
socket pattern is caused to slide on to the cone C when at the upper end of the
moulding box and is worked by a seperate ram J, Fig. 2. The methoil of work-

page_text: ing is as follows. The ram D together with the cone C and measuring tube G
having been lowered to the bottom position, and the sand or other moulding
material filled in between the measuring tube G, and the inner walls of the
moulding box A, the ram D is caused to ascend, and forces the cone C, through
the sand and compresses the sand against the inner walls of the moulding box A
and thus forms the body part of the mould. During the last few inches of the
upward stroke of the ram E the enlarged portion K of the ram 1) enters the
mould, and thus forms the spigot of the mould, or if the spigot pattern K is a
loose sleeve working over the ram D and moved by a seperate ram or the like,
it may be forced into the moulding material at any time, and thus form the spigot
of the mould quite independently of the motion of the ram D. The ram D
having completed its stroke and thus having moulded the body of the pipe, and
the spigot having been formed at the lower end of the mould as already described,
the socket pattern F which is made to slide on the cone C, is forced into the
sand at the upper end of the mould, by another cylinder or ram as shown at
Fig. 2, and thus forms the socket of a pipe to be cast with the socket up. This
completes the operation of moulding a pipe & the rams and patterns are now
withdrawn & put in position for the next pipe to be made.
At Fig. 3 is shown a method of making pipes which are specified to be cast
with the socket down & the spigot up. In this case the socket pattern F is
shown solid or fixed upon the lower portion of the ram D and travels with it,
whilst the spigot pattern K (Fig. 3) is a seperate pattern placed and ecured
to the upper flange of the moulding box A when required. The ram D and
measuring tube G having been lowered to its bottom position and the moulding
material placed in the box, the spigot pattern K is fixed in its place, the ram is
caused to ascend and moulds the body of the pipe, and the upward push of the
ram presses the sand round about the spigot pattern K and thus forms the
spigot of the mould, and in like manner at the latter end of the stroke of the
ram ), the socket pattern F is forced into the lower end of the mould and
thus forms the socket of the mould. It is quite clear that either the spigot
pattern or the socket pattern F could be pressed into the sand quite indepen-
dently of the motion of the ram 1) by any suitable mechanical arrangement and
it is is also clear that if when the ram 1) had completed its outward stroke, and
a spigot pattern or a socket pattern was then attached to the ram or cone, the
reverse motion of the ram could be caused to draw the spigot or the socket pattern
into the moulding material at the upper end of the moulding box. If found
convenient the lower end of the ram or pattern could be caused to pass through
a guide at its lower end, and one end of the measuring tube G, (or its equiva-
lent) could be attached to the small end of the cone, and the other end to a ram,
piston, or any other suitable motive power, and the cone, could thus be drawn
through the sand and thus form the mould. It is evident that for given
diameters of the cone C, body pattern D and internal diameter of the moulding
box A there is one diameter of measuring tube G or its equivalent, which will
give the proper density of the mould when compressed and that the density of
the moulding material may be varied at will using varying diameters of measur-
ing tubes, or the like. It will be seen that in like manner, spigot and flange
pipes, double spigot pipe, double flanged pipes or any desired combination of
these may be moulded having loose pattern pieces, or patterns made in one
or several pieces, either attached or detached from the cone or cones, so that
they may be worked in connection with the cone, ram, or other convenient point
of attachment, and in such a manner that the combination of a cone or conica!
shaped pattern, a measuring tube or its equivalent, all of which may be varied
in form to suit varying circumstances. This machine may be worked by
hydraulic power, by steam, or by compressed air, hydro-pneumatic or any other
suitable motive power, and the cone or cones, body patterns, spigots, sockets, or
flange patterns, the measuring tube shaft or gauge or its equivalent may each
be worked by the same ram, or each of the said portions may be worked by

page_text: seperate rams pistons or whatever power may be used, so that they may all have
one motion or may be worked independently of each other and each portion of
the pattern or patterns, or cones, may be mounted upon one or seperate carriages
or bogies, or they may be fixed upon one or seperate bedplates, entablatures or
the like, and may be arranged to hook vertically, horizontally, or at any suit-
able angle.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. A machine for moulding spigot and socket pipes, flange pipes and the
like, by means of a conical or tapered die or dies, or by conical shaped or tapered
patterns, which are forced or passed through or into the sand or other moulding
material, so that all, any or every portion of the pipe mould, may be moulded by
compression within the mould as herein described.
2nd. The use of a measuring tube or gauge for measuring the amount of sand
required for the mould of a spigot and socket pipe, flange pipe and the like,
when the sand or other moulding material is compressed by and during the
passage of a cone, cones, conical shaped or tapered pattern, or patterns, through
the moulding material, as and for the purpose herein described.
3rd. The use of a moveable carriage for carrying a cone, conical shaped or
tapered pattern, or patterns, so that a machine for moulding spigot and socket
pipes, flange pipes and the like, by means of a cone, conical shaped or tapered
pattern or patterns, together with the guide guides, rams, cylinders, through or
by which the cone, pattern, or the equivalent thereof is worked; may be moved
to and from the moulding box or boxes as described herein.
4th. A machine for moulding spigot and sccket pipes, flange pipes and the
like, by means of the combination and use of a cone or cones, conical shaped
or tapered patterns, which produce a pipe mould by compression of the mould
from within, together with a measuring gauge for fixing and regulating the
amount of sand or other moulding material all as described herein.
5th. A machine for moulding spigot and socket pipes, flange pipes and the like,
by the joint use and combination of a conical or tapered die or dies, a cone, cones,
or conical or tapered shaped patterns, or pattern which compresses the mould
during its passage through or into the moulding material, and worked by or
through guides, or by rams, cylinders, pistons, or the like, mounted upon a
moveable carriage as herein described.
