IMPROVE- MENTS IN MAKING MOULDS FOR CASTING, AND IN APPARATUS THEREFOR
Year: 1863

page_text: LETTERS PATENT to James Norie, of Glasgow, in the County of Lanark,
North Britain, Ironfounder, for the Invention of "IMPROVEMENTS IN
Sealed the 2nd November 1863, and dated the 9th May 1863.
PROVISIONAL SPECIFICATION left by the said James Norie at the Office
of the Commissioners of Patents, with his Petition, on the 9th May
1863.
I, JAMES NORIE, of Glasgow, in the County of Lanark, North Britain,
Ironfounder, do hereby declare the nature of the said Invention of "IMPROVE-
MENTS IN MAKING MOULDS FOR CASTING, AND IN APPARATUS THEREFOR," to be
as follows, that is to say:-
This Invention relates to an improved system applicable in making moulds
for casting combined sleeper chairs for railways, and other articles, and has
principally for object to economise labour, and to simplify and expedite the
cycle of operationis.
In carrying out the Invention according to one modification, the main or
lower mould box, in which the upper surface of the sleeper chair is moulded, is
mounted by journals or trunnions in the frame of a small carriage. The
pattern is attached to a plate or frame, and when not connected to the mould
box is supported by slides capable of being moved vertically in stationary
guide standards by levers or equivalent means. The pattern being in an
inverted position, the mould box on its carriage is brought under it, and the

page_text: pattern is lowered into and secured to the mould box by catches or latches;
the mould box with the pattern connected to it is then turned over on its
journals, and the sand is rammed in, after which plates are fitted in to sustain
the sand. The box is then turned over back again, and the pattern is elevated
by the slides. The various catches or latches are connected with a self-acting
detent, by which the box is prevented from being turned over, except when
the parts are properly adjusted. The mould box is next moved away from
the stationary standards on rails to a position where the top box, moulded
in the ordinary way, is placed in position, either by hand or by means of a
frame, which facilitates its adjustment. The mould then proceeds onwards to
receive the molten metal, and afterwards to discharge the casting, which
operation is effected by simply turning over the mould box on its journals.
It is preferred to dispose the rails in two lines parallel to each other, and at
each end to arrange at a slightly lower level a carriage or table running round
a centre pin and on a circular rail, which receives each mould carriage in turn
and transfers it from one line of rails to the other. With this arrangement the
mould carriages circulate continuously, and the mould boxes never require to
be disconnected from their carriages, except for repairs, whilst the various
arrangements work together conveniently, and dispense with much manual
labour that is required by other systems.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Norie in the Great Seal Patent Office on the 9th
November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
NORIE, of Glasgow, in the County of Lanark, North Britain, Ironfounder,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Norie, Her special licence that I, the said James Norie,
my executors, administrators, and assigns, or such others as I, the said James
Norie, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MAKING MOULDS FOR CASTING, AND IN APPARATUS THEREFOR," upon the condition
(amongst others) that the said James Norie, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent..
NOW KNOW YE, that I, the said James Norie, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say:-
My said Invention relates to an improved system applicable in making
moulds for casting combined sleeper chairs for railways, and other articles,
and has principally for object to economise labour, and to simplify and expedite
the cycle of operations.
And in order that my said Invention, and the manner of performing the
same, may be properly understood, I have hereunto appended a Sheet of
explanatory Drawings to be herein-after referred to, and representing a
modification of apparatus for carrying out my improvements.
Figure 1 is an end elevation, and Figure 2 is a side elevation of my
improved apparatus with a mould box 1 on its carriage 2, shown as just
brought into position to be dealt with; and Figure 3 is a plan of the mould
5 box with the pattern plate on it; Figure 4 is a plan, and Figure 5 is a
sectional elevation showing arrangements for carrying on the work con-
tinuously.
In carrying out the Invention, the main or lower mould box 1, in which
the upper surface of the sleeper chair is moulded, is formed with journals or
trunnions 3, by which it is suspended in bearings in standards 4 at the opposite
ends of a mould carriage 2, which is fitted with wheels 5 to run upon rails 6.
The pattern or patterns indicated by dotted lines in Figure 2 are attached to a
plate or frame 7, which, when not connected to the mould box 1, is supported
by four slides 8, capable of being moved vertically in four stationary guide
5 standards 9, situated two at each side of the pair of rails 6. The two vertical
slides 8 on each side are connected by a horizontal bar 10, and this bar 10
has jointed to it a link 11 jointed to the end of one 12 of a pair of levers on
a transverse horizontal shaft 13, turning in bearings beneath the rails 6. The
parts are balanced by a counterweighted lever 14 fixed on the shaft 13, and

page_text: this shaft is turned by a band lever 15. On one side the vertical slides 8
when lifted come in contact with the under side of the pattern plate 7, but on
the other side the slides 8 when lifted act on latches 16 jointed on the top or
outer surface of the pattern plate. When the mould box 1 is brought into
position, as represented in the Figures, under the pattern plate 7, this plate is
lowered upon it by depressing the slides 8, and is fixed to it by means of a
rocking shaft 17 on the plate, and formed with hooks 18 at the ends, which
take hold of studs 19 formed for the purpose on the sides of the box. The
locking movement of the rocking shaft 17, also by means of a cross bar 20,
shifts the latches 16 out of the way of the slides 8. The mould box 1, with
the pattern plate 7 thus connected to it, is then turned over on its journals 3,
and the sand is rammed in from the side, after which plates are fitted in to
sustain the sand. The box 1 is then turned over back again, the latches 16
are shifted over the slides 8, the pattern plate being at the same time unlocked
from the box by means of the rocking shaft 17, and the pattern is then
elevated from the sand mould by means of the slides 8. When the mould
carriage 2 is moved along the rails 6 to the apparatus, it is stopped and held
in position by means of a spring, detent, or latch 21 jointed to one of the
rails, and formed with a foot plate 22, by means of which it is depressed to
allow the carriage to proceed after the mould has been formed. The carriage
is moved away from the standards 9 on the rails to a position where the top
box, moulded in the ordinary way, is placed in position, either by hand or by
means of a frame, which facilitates its adjustment. The mould on its carriage
then proceeds onwards to receive the molten metal, and afterwards to discharge
the casting, which last operation is effected by simply turning over the mould
box on its journals. I prefer to dispose the rails 6 in two lines parallel to each
other, as shown in Figure 4, and at each end to arrange at a slightly lower
level a carriage or table 23 running round a centre pin or pillar 24 on a circular
rail 25, which receives each mould carriage in turn, and transfers it from one
line of rails to the other. Instead of the turning rails 25 there may be
straight lines of lower rails running across at the ends of the upper lines of
rails, and the mould carriages may be transferred from one upper line of rails
to another on carriages running on the lower cross rails. Such lower cross
rails may be extended so as to connect any number of upper lines of rails.
With the arrangements herein-before described the mould carriages circulate
continuously, and the mould boxes never require to be disconnected from their
carriages, except for repairs, whilst the various arrangements work together
conveniently, and dispense with much manual labour that is required by
other systems.

page_text: Having thus particularly described my said Invention, and the manner in
which the same is or may be performed, I have to state that I do not restrict
myself to the precise details herein described or delineated; but that what I
believe to be novel and original, and claim as the Invention secured to me
by the herein-before in part recited Letters Patent, is, the making of moulds
for casting in the improved manner, and by means of improved apparatus,
substantially the same as herein-before described.
In witness whereof, I, the said James Norie, have hereunto set my hand
and seal, this Sixth day of November, in the year of our Lord One
thousand eight hundred and sixty-three.
Witness,
EDMUND HUNT,
Patent Agent,
