AN IMPROVED MACHINE FOR MAKING SAND MOULDS FOR METAL CASTINGS
Year: 1885

page_text: PROVISIONAL SPECIFICATION.
I FRED RYLAND of West Bromwich in the County of Stafford Ironfounder do
hereby declare the nature of the said invention for AN IMPROVED MACHINE FOR
MAKING SAND MOULDS FOR METAL CASTINGS to be as follows:-
This invention consists in the construction of a revolving table with one two or
more turn over plates, for carrying the moulds. The table is provided with cast
iron arms having bearings for the plates to rest in, these bearings being formed to
allow of the plates being lifted. The revolving arrangement is obtained by a
circular path being formed on the underside of the revolving table and a corre-
sponding path being formed on the stationary stand beneath the table, between
these two paths run three or more rollers working free on their axles which are at
the end of guides or arms extending from the centre. The operation may be
described, as follows, when a table carrying four plates is used the mould box is
placed upon one of the plates the table is partly turned and whilst another box is
being placed upon the next plate the first one is being filled with sand. The table
then passes this first plate round under an hydraulic or other press which is brought
down upon it in the ordinary way to form the mould whilst the second and third
plates are receiving the box and the sand, the first plate is then passed on round
to an ordinary take off table when it is turned over to remove the mould whilst
the second third and fourth plates are cach going through the previous operations.
The advantage gained by the use of this turn table arrangement is that whilst
one mould is being pressed others can be prepared and placed to immediately go
through the same process.

OFFUIFICATION
I FRED RYLAND of West Bromwich in the County of Stafford Ironfounder do
hereby declare the nature of the said invention for AN IMPROVED MACHINE FOR
MAKING SAND MOULDS FOR METAL CASTINGS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings and to the letters
and figures marked thereon:-
This invention consists in the construction of a revolving table with one two or
more turn-over plates for carrying the moulds.
The table is provided with cast iron arms having bearings for the plates to rest
in these bearings being formed to allow of the plates being lifted. The revolving
arrangement is obtained by a circular path being formed on the underside of the
revolving table and a corresponding path being formed on the stationary stand
beneath the table. Between these two paths run three or more rollers working
free on their axles which are at the ends of guides or arms extending. from the
centre.
I will now proceed to describe the machine and its operation by aid of the
accompanying drawings which illustrate a table carrying four plates.
Figure 1, is a plan of the top of a revolving table and Figure 2 is a section of
the machine.
(a³, a³, a³, a¹) are the cast iron arms with bearings for the plates (b, c, d, c).
(f) is the circular path formed on the underside of the revolving table with the
corresponding path (g) formed on the stationary stand (h). (ii) are the rollers
working free on their axles at the ends of the guides or arms (ij).
A mould box (x) being placed upon the plate (b) the table is partly turned (one
fourth of its travel in the instance illustrated) and whilst another box is being placed
by a workman at (a) upon the plate that has come before him the first named plate
is being filled with sand by a workman at (a) the table then passes this first plate
round under an hydraulic or other press at (a³) which press is brought down upon
it in the ordinary way to form the mould whilst the box on the second plate which
bas reached the workman at (a) is being filled with sand and the third plate at (a)
is receiving a box to be filled. The first plate is then passed on round to an
ordinary take off table at (u') where it is turned over to remove the mould, whilst
the second third and fourth plates are each going through the previous operations.
The advantage gained by the use of this turn table arrangement is that whilst
one mould is being pressed others can be prepared and placed ready to immediately
go through the same process.

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
A revolving table for the purpose of facilitating the making of sand moulds for
metal castings substantially as herein set forth and specified.
