PROVISIONAL SPECIFICATION.
A Steam Moulding and Core Making Machine.
JOB SHEPHERD 15 Stockport Road Lower Bredlury Stockport Moulder
do hereby declare the nature of this invention to be as follows:-
A steam moulding and core making machine for making pipes, columns, retorts etc.
A vertical cylinder with a D shapped piston rod supported on two fixings. At the
end of the piston rod will be attached one, or more, cylinderical or other shapped
rammers, the same to be worked by an ordinary handle similar to a steam hammer.
At the bottom and fitting in between the fixings, will be a plate, in which will be
a taper tube or more if required. Underneath this plate will be attached to each
hole a taper tube larger than each rammer, the wide part of which will be in the
hole of the plate, to be leavel with the surface of the same, the small end below the
surface, to be a little larger than the rammer. On the surface and not fur from
the edge of each hole, will be fixed a few pillers. At the top of each piller, will be
a bracket pointing inwards to hang over and to be nearly in line with the small end
of the taper tube on the points of the brackets will be fixed the outward flange of
a short straight tube the tube to suspend downwards the bottom end of the tube to
be without flange and to be leavel with the plate surface another inner tube with
a flange on one end only to slide in the one on the pillers the outward flange of this
tube will rest on the top of the suspended tube the other end of this inner tube will
reach down to the bottom of the taper tube, and about the same diam. as the latter
this will form a hopper or receptical to receive and hold sand when the inner
tube is raised the sand will fall below into the moulding box the fall of the rammer
down the inner tube will press the sand firmly between the moulding box and the
pattern. The same method will be adopted in making cores with this exception
instead of a moulding box there will be a core box and instead of a pattern there
will be a core barrel.

page_text: JOB SHEPHERD, 15, Stockport Road, Lower Bredlury Bredbury, Stockport,
Moulder, 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 :-
My invention consists of an arrangement for ramming soil such as loam, sand,
or other similar substanee moulding material in one or more mould or core boxes
for the purpose of forming suitable moulds and cores for use in the casting of pipes,
columns, cylinders, retorts, and similar contrivances. articles. The object of my
invention is to facilitate the manufacture and lessen the cost of production of these
articles, and also to give produce more satisfactory moulds than usual.
To effect this result, I propose to use a machine such as shown partly in elevation
and partly in vertical section in the accompanying drawing. This machine comprises a
rammer R of suitable form and size, and constructed to slide on a pattern P, and in
within a easting or moulding box M, the rammer which in the example shown, is of
hollow cylindrical form for the production of hollow cylindrical moulds, being connected
at its upper end to a piston rod corresponding to the piston rod of an ordinary
steam hammer of which C is the steam cylinder and V the valve chest. The
piston rod may if desired, be made of any suitable shape to prevent the rammer
moving turning round. H is a stationary hopper in which the soil, sand, or other
material is placed. whilst (S)-is-a-slide, which on being lifted allows the sand to fall
from-the hopper into-the-mould-below. This slide is-so-arranged as to be lifted
when the rammer reaches-a-certain-height-in-its-upward stroke, and is-elosed by
the-descent of the rammer.
The deseent-of-the-rammer-(R) will cause the soil or sand to be pressed-hard
against the pattern-(P), which is then withdrawn.
It consists of a taper tube carried by a plate arranged between the fixings or standards
carrying the steam cylinder C as shown, the lower end of the tube being a little larger in
diameter than the cylindrical rammer R. S is an inner tube arranged to work vertically
in a short straight outer tube that serves as a fixed guide and which is carried as shown
by brackets at the top of pillars or flanges fixed in the tube H, the inner diameter of the
said guide tube corresponding approximately to the diameter of the lower end of the
tube H. The tube S, which forms a tubular slide or valve to control the discharge of
material through the bottom of the hopper, is formed with an external flange that rests
upon the top of the guide tube when the said slide closes the discharge opening, and with
an internal flange arranged in the path of a flange shown on the rammers, the arrangement
being such that when the rammer rises to a certain extent it will lift the slide S and allow
sand or other material to fall from the hopper uniformily all around the rammer into the
mould box below, and on the descent of the rammer the slide will fall by gravity and cut
of the further supply of sand or other material to the mould box, that already delivered
being tightly compressed within the mould box and around the pattern P by the rammer
on the continued descent thereof. The foregoing operations are caused to take place in
rapid succession by suitably controlling the supply of steam to and from the motor
cylinder C, until the mould box is filled to the required extent, whereupon it is removed,
preferably by a wheeled vehicle as shown, and the pattern withdrawn preparatory to the
mould being used for casting purposes.
When making cores, the pattern P will be substituted replaced by a hollow box
or core barrel of suitable form, and the easing mould box M will be substituted
replaced by a suitable core box, and which may be made in parts so as to open a
suitable rammer will be being fixed in the place of R.

page_text: 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. The In a machine for making moulds and cores for use in casting pipes, columns
retorts and like articles, the combination of with a steam or air cylinder, with
necessary valves, and with having its piston rod, to which is connected to a suitable
hollow rammer for pressing the adapted to press soil sand or other material into a
mould or core boxes, for the purpose of forming moulds or cores, as used in the
easting of pipes, columns, cylinders, retorts, and similar contrivances.
2. The combination with the said ramming arrangement of a stationary hopper
and a slide, the latter of which is adapted to be lifted automatically by the upward
movement of the rammer so as to permit of soil, sand, or other material to fall
falling from the hopper into the mould or core box at the desired time substantially
as hereinbefore described with reference to the drawing annexed.
