Improvements in or connected with Moulding Machines.
We, BENJAMIN BROWN, of Brookfield, Ditton, in the County of Lancaster,
Engineer, and ANDREW POULSON, of 63, Frederick Street, Widnes, in the County
of Lancaster, Moulder, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to machinery for foundry moulding, and has for
its object, amongst other things, to provide improvements in such machinery,
by which machine moulding can be more advantageously and generally employed
in the foundry, and by which, also, the cost of labour connected with the present
moulding machinery, and moulding operations generally, in the foundry, can
be very considerably diminished.
A moulding machine according to this invention, is portable, that is to say,
it is so made that it can be lifted or moved about the foundry from point to
point by hand (or by suitable appliances) to the spot where the moulder's work
is to be performed (in contradistinction to the work having to be taken to and
from the machine), while, at the same time, it is of simple construction, and
light, yet effective and accurate. The machine or apparatus consists of a frame
or cage of metal, or other suitable material, forming the body of it, and the.
pattern is mounted upon the upper part or face of the frame. The moulding.
box is clamped onto the frame, and the sand is filled in and rammed from above.
When the filling or ramming is finished, the frame, with the box, is turned over,
so that the box is at the bottom. The projecting part or parts of the pattern,.
such as flanges, webs or the like, are made movable, and are withdrawn from
the sand by suitable means, as hereafter described, and then the whole frame
containing the pattern is lifted off, and can be taken to another point and turned
back with the pattern uppermost, and the operation repeated.
In one form, the frame or cage is rectangular in form, and built up of angle
bars of any suitable material, or bars of other suitable section, producing a
cage like, or other convenient structure; whilst the upper part or platform will
comprise angle or other bars running from end to end, some of which are pre-
ferably detachable, and made to the form of the body, or the main portions of
the pattern and castings to be produced; and to these parts this part of the
pattern is attached, and forms part of the machine, and is not movable. The
flanges, webs, or like projecting parts of the pattern on the other hand, are
separate from the body. and are adapted to be moved, and to be withdrawn from
the mould, their operation being effected by gearing having a direct and straight
thrust, and giving no canting, or motion other than that directly in the line
these parts are desired to move; whilst they are guided at the same time in the
frame, between the body of the pattern, and side members of the frame, or at
other points, as the case may be. The gearing which will advantageously pro-
vide this straight movement, and give unfailing accuracy, consists of rack slides
connected at their upper ends-say at two or more parts to a bar carrying the
moving part or parts of the pattern, and working in V or like guides, vertically

page_text: up and down; while these slides are operated by pinions mounted on shafts
extending through the frame, and suitably supported in bearings at the ends
(and at one or more intermediate points, if desired); whilst a ratchet toothed
wheel and pawl, or equivalent mechanism is employed upon the shafts to hold
these parts in the position they take in the moulding or filling operation.
In one construction, the bars extending longitudinally of the frame, to which
the body of the pattern is affixed, are detachable; while at the sides, outside,
there are longitudinal frame plates of channel section, or other suitable section,
forming a rigid and fixed part of the frame along the face of the machine, at
each side.
Of course, for different kinds and shapes of patterns, or to meet special cases,
the frame or cage will be differently shaped and arranged, more particularly
at the upper part.

Improvements in or connected with Moulding Machines.
We, BENJAMIN BROWN, of Brookfield, Ditton, in the County of Lancaster,
Engineer, and ANDREW POULSON, of 63, Frederick Street, Widnes, in the County
of Lancaster, Engineer, 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:―
This invention has reference to machinery for foundry moulding, and has for
its object, amongst other things, to provide improvements in such machinery,
by which machine moulding can be more advantageously and generally employed
in the foundry, and by which, also, the cost of labor connected with the present
moulding machinery, and moulding operations generally, in the foundry, can
be very considerably diminished.
A moulding machine according to this invention, is portable, that is to say,
it is so made that it can be lifted or moved about the foundry from point to
point by hand (or by suitable appliances) to the spot where the moulders work
is to be performed (in contradistinction to the work having to be taken to and
from the machine), while, at the same time, it is of simple construction, and
light, yet effective and accurate. The machine or apparatus consists of a frame
or cog of metal, or other suitable material, forming the body of it, and the
pattern is mounted upon the upper part or face of the frame. The moulding
box is clamped onto the frame, and the sand is filled in and rammed from above.
When the filling or ramming is finished, the frame, with the box, is turned over,
so that the box is at the bottom. The projecting part or parts of the pattern,
such as flanges, webs, or the like, are made movable, and are withdrawn from
the sand by suitable means, as hereafter described, and then the whole frame
containing the pattern is lifted off, and can be taken to another point and turned
back with the pattern uppermost, and the operation repeated.
In one form, the frame or cage is rectangular in form, and built up of angle
bars of any suitable material, or bars of other suitable section, producing a
cage like, or other convenient structure: whilst the upper part or platform will
comprise angle or other bars running from end to end, some of which are pre-
ferably detachable, and made to the form of the body, or the main portions of

page_text: the pattern and castings to be produced; and to these parts this part of the
pattern is attached, and forms part of the machine, and is not movable. The
Hanges, webs, or like projecting parts of the pattern on the other hand, are
separate from the body, and are adapted to be moved, and to be withdrawn from
the mould, their operation being effected by gearing having a direct and straight
thrust, and giving no canting, or motion other than that directly in the line
these parts are desired to move; whilst they are guided at the same time in the
frame, between the body of the pattern, and side members of the frame, or at
other points, as the case may be. The gearing which will advantageously pro-
vide this straight movement and give unfailing accuracy, consists of rack slides
connected at their upper ends-say at two or more parts--to a bar carrying the
moving part or parts of the pattern, and working in ✓ or like guides, vertically
up and down; while these slides are operated by pinions mounted on shafts
extending through the frame, and suitably supported in bearings at the ends
(and at one or more intermediate points, if desired); whilst a ratchet toothed
wheel and pawl, or equivalent mechanism is employed upon the shafts to hold
these parts in the position they take in the moulding or filling operation.
In one construction, the bars extending longitudinally of the frame, to which
the body of the pattern is affixed, are detachable; while at the sides, outside,
there are longitudinal frame plates of channel section, or other suitable section,
forming a rigid and fixed part of the frame along the face of the machine, at
each side.
Of course, for different kinds and shapes of patterns, or to meet special cases,
the frame or cage will be differently shaped and arranged, more particularly
at the upper part.
The invention, the characteristics of which are above described, is illustrated
in the accompanying drawings, which shew one form of machine hereunder,
adapted for the moulding of curved flanged plates; but, of course, the invention
is not restricted to this form, as in its application for the moulding of articles
of different forms, or to meet special cases, it will necessarily be modified as to
form, and disposition of parts, to suit the same.
In these drawings Figure 1 is a side elevation, and Figure 2 a cross section.
The cage or frame forming the body of the machine, in the case shewn, is
comprised mainly of longitudinal channel bars a and intermediate angle bars b,
extending from end to end of the frame, and forming the upper portion thereof;
the angle bars e also extending from end to end; and end frames consisting of
angle bars d d at the top and bottom, respectively, and 2 at the sides. These
angle bars of these end frames are connected together, and the side and upper
frame bars a, b, and c, connected to them.
In the case shewn, two intermediate plates e are provided, they being connected
with the angle irons c and b. These bind and hold the frame bars between the
end frames, together. The frame may be enclosed at the side and ends by suitable
planking as indicated at f in Figure 2.
The pattern, in the case shewn, is for a curved and flanged or sector plate;
and hence, the upper part or floor of the frame is carried downwards to correspond
with the curvature.
The pattern centre portion, or plate proper, is designated h, and is fixed onto
the intermediate angle bars b; whilst the side flanges, which are adapted to be
drawn out of the mould when made, and the frame turned over, are designated i,
and are mounted upon angle bars j, fixed upon the upper ends of the rack bars k,
of which there are two on either side. These racks are worked up and down by
toothed pinions & mounted on shafts m supported in bearings m¹ at intermediate
points, and m² at the ends.
The racks move up and down in, and are guided by guides n, which are in
the form of brackets fixed on the angle bars c.
The end flanged portions of the pattern are similarly moved up and down,
and held up in position, by racks o, which are suitably guided; these racks being

page_text: moved by tooth pinions p, mounted on the transverse shafts p³, at each end of
the frame.
Thus both the side flanges 2, and the end flanges i¹ are moved and held up in
position by the rack bars k and o respectively, and are drawn down out of the
mould by them. The floor level proper of the machine is that of the upper
surface of the boards q, which form the floor of the frame outside the pattern;
whilst the thickness of the plate to be cast will be due to the amount of projection
of the upper surface of the pattern plate h above the level of q.
The moulding box is placed upside down on the floor 9 of the frame, and
clamped by suitable means down on to it.
In use, the frame with the pattern in position, with the projecting parts
standing up, the moulding box is filled with sand and rammed; and when
this portion of the operation is complete, the frame with the box is turned over,
so that the box is at the bottom. The flanged portions and of the pattern
are then drawn out of the mould through their rack bars and o, and the whole
frame containing the pattern is lifted off the mould; when it can be taken to
another point and turned back with the pattern uppermost, and the operation
repeated.
According to the different kinds of castings, to be made, will of course depend
the form and size of the frame; as for instance, in some cases, the pattern may
consist practically wholly of upwardly projecting parts, in which case the whole,
or practically the whole of the pattern may be movable similar to the flanges
of the pattern shewn in the drawing. Also, in some cases, several patterns may
be mounted on a single frame, so that castings in multiple of the object to be
produced can be made, in which case, of course, the upwardly projecting parts
will be drawn down in a similar manner to those referred to.
Further, in some cases, different projecting parts of a pattern may be drawn
out of the mould by separate mechanisms, and in different directions or inclin-
ations, accordingly as the nature and character of the pattern may demand.
Having now particularly described and oscertained the nature of this
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. The herein described improved moulding machine, namely, a machine
consisting of a frame work or body having upon its upper part or surface the
pattern of the article to be cast, parts, or the whole of which, are, or is, adapted
to be withdrawn; substantially as and for the purposes set forth.
2. A portable moulding machine consisting of a frame, and movable parts
for withdrawing parts, or the whole of the pattern; arranged or constructed,
and adapted to operate substantially as set forth with reference to the drawings.
3. The portable moulding machine having parts constructed, arranged, and
adapted to be operated, particularly as shewn in and set forth with reference
to the drawings.
