Improved Frames for Supporting Pattern Plates and Moulding, Boxes
on Moulding Machines.
CHARLES WILLIAM COLEMAN, 48, Stamford Street, Old Trafford, Manchester,
Moulder, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to allow of patterns being cast or fastened on
both sides of the pattern plate without interfering with other portions of the
machine.
The ordinary pattern plates used in molding machines, rest on and are fastened
to frames of such shape and are so placed in the machines that patterns can only
be fastened upon one surface of the plate necessitating twice as many plates for
patterns as would be the case if both sides of the plates could be utilised.
These improved frames consist of (1) an inner frame arranged to support and
hold the pattern plate at such an increased height, and in such a manner as to
allow of patterns and projections on the lower side of same without coming in
contact with other portions of the machine.
This inner frame is supported by and fastened to the ordinary supporting frame
for the plate (2) an outer frame provided with the nescessary pins, lugs, bush-
ings, etc. for holding and supporting the molding boxes at the right height to
suit the elevated pattern plate. This outer frame rests upon and is fastened to
the ordinary supporting frame for the molding box.
These improved frames being fastened to the ordinary frames of the machine
will partake of their respective motions in making the mold and in drawing the
patterns from the mold, they conform, at their lower ends, in shape and size to
the ordinary plates and frames, to which they are fastened, but the upper ends
may be arranged for different sizes and shapes of plates and molding boxes.
Improved Frames for Supporting Pattern Plates and Moulding Boxes
on Moulding Machines.
I, CHARLES WILLIAM COLEMAN, of 48, Stamford Street, Old Trafford, Manches-
ter, in the County of Lancaster, Moulder, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement:—
This invention relates to improvements in or in connection with moulding

page_text: machinery used for casting iron and other metals and whilst applicable to nearly
all moulding machines for this purpose is especially applicable to machines of
the Tabortype. The object of the invention is to provide improved means
for supporting the pattern plate and moulding box so as to enable patterns pro-
jecting on both sides of the pattern plate to be more readily moulded than has
hitherto been the case and without interfering with any other portions of the
machine. The ordinary pattern plates used in moulding machines rest on and
are secured to frames of such shape and are so placed in the machine that patterns
can only be fastened upon one face of the plate, necessitating twice as many
plates for patterns as would be the case if both sides of the plate could be utilised
as in my invention.
"
"
My invention may be carried into practice in several ways without departing
from its general character, and the accompanying drawings show one way
which I adopt at present. In these Fig. 1 is a vertical section of so much of a
Tabor" moulding machine as is necessary to illustrate the application of my
invention, the parts being shown in the position they assume before the pattern
is drawn," whilst Fig. 2 is a similar view when the pattern is "drawn," Fig. 3
is a plan of the moulding box carrier with a stripper plate mounted on top of
it, and Fig. 4 is a plan of the frame for supporting the plate carrying the pattern.
In these the moulding of a spur wheel is shown, A being the moulding machine
table which may be vibrated by a suitable engine or not as desired, B is the rising
and falling table, C is the moulding box, D is the spur wheel pattern and E is a
stripper plate faced with a toothed ring F of Babbitt metal. All these parts are
of the ordinary construction.
For supporting the pattern plate at an increased height from ne table A of
the machine and in such a manner as to allow of patterns and projections on the
lower side of same without coming into contact with other portions of the
machine (as indicated in Fig. 1 where a portion of the wheel D is shown) I
mount on the table A a metal frame G of rectangular construction, as shown, or
of any other shape suitable to the work in hand. This frame is firmly secured to
the table in a suitable way. Preferable I secure it by cutting part of its corners
away as at H and passing through the lower portions left, screws I which engage
with the table A. At the upper edge the frame G may be enlarged in its section
but it is always provided with two or more holes J into which screws may be
passed through holes in the pattern plate K which it is to support. It is further
provided with dowel holes L to receive dowel pins M fixed to the pattern plate.
The top of the frame G and both sides of the pattern plate K are machine faced
to secure a firm joint and the pattern is secured to the latter by screws N as
shown in Figs. 1 and 2, or in any other suitable way. The pattern plate K may
be plain on both sides and have one half of a pattern or some projecting portion
on its lower side, or a different pattern, as in Fig. 1.
ears,
In order to support the moulding box C to agree with the frame G I firmly
secure to the "drawing" frame of rising and falling table B a second rectangular
frame somewhat of the section shown and provided with projecting flanges or
P and Q the former serving to enable it to be bolted or otherwise secured
to the frame B by bolts R whilst the latter serves to carry dowel pins S that
pass into the holes of the ordinary or special ears T formed on the moulding
box C. The frame is of such a depth that when the "drawing frame is in its
lowermost position its top edge is level with the upper face of the pattern plate K
as shown in Fig. 1. To enable any sand to escape that may find its way down
into the space between the frames G and O, I form in the latter a series of holes U.
It will be understood that the improved frames being fastened to the ordinary
frames of the machine will partake of their respective motions in making the
mould, and in drawing the patterns from the mould. They conform at their
lower ends in shape and size to the ordinary plates and frames, to which they are
fastened, but the upper edge may be arranged for different sizes and shapes of
plates and-moulding boxes.

page_text: 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:-
1. In machines for making moulds for metal castings the use of frames such as
Gand for supporting the pattern plates and moulding boxes together with the
means of securing them to the latter and to the table and drawing frame of the
moulding machine substantially as and for the purposes described.
2. The general construction, combination and arrangement of parts forming
my improvements in frames for supporting pattern plates and moulding boxes
in machines for making moulds for metal castings substantially as described and
shown with reference to the accompanying drawings.
Dated this 18th day of September 1900.
