PROVISIONAL SPECIFICATION:
Improvements in Apparatus for Moving Metals in connection with
Rolling Mills.
We, JOHN FULTON MILLER, of Vulcan Foundry, Coatbridge, in the County of
Lanark, North Britain, and FINLAY FINLAYSON, of the same place, Engineers, do
hereby declare the nature of this Invention to be as follows, that is to say :-
Our said Invention relates to apparatus for the same purposes and to some extent
of the same kind as that described in the Specification of Patent No. 4236 of 1885,
obtained by Finlay Finlayson one of us; and the object of the present Invention is to
render parts of the apparatus advantageously applicable for turning over ingots, or
blooms, or masses of metal in different directions.
In carrying out the Invention there is provided at each part of the rolling machinery
where the metal masses have to be moved across or turned over, a truck with wheels
on rails or a frame sliding on guides which is arranged to be moved across by a
horizontal hydraulic cylinder. Each truck or sliding frame has on it a central table
or support to which there are hinged or jointed two plates or leaves one at each side
and each connected by a link or links to the ram of a vertical hydraulic cylinder
fixed on the truck or sliding frame. The side plates or leaves can be turned out-
wards from a vertical position into a horizontal position; and they can also be
turned inwards to a small extent. The vertical hydraulic cylinders are by preference
made double acting, so as to insure that the rams will draw over the side plates
or leaves when they have been turned inwards; and the double action may be
obtained by having pressure constantly on the upper annular surface of each
piston, the under side of each piston being made large enough for the pressure on
it to lift what is required in addition to balancing the downward pressure on the
annular surface. The water communications for the vertical cylinders on the trucks
or sliding frames are made by means of telescopic pipes as in the apparatus
described in the earlier specification hereinbefore referred to.
Dated this Twenty-first day of February 1889.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Moving Metals in connection with
Rolling Mills.
We, JOHN FULTON MILLER, of Vulcan Foundry, Coatbridge, in the County of
Lanark, North Britain, and FINLAY FINLAYSON, of the same place, Engineers, 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, that is to say :-
Our said Invention relates to apparatus for the same purposes and to some extent of
the same kind as that described in the Specification of Patent No. 4236 of 1885
obtained by Finlay Finlayson, one of us, and the object of the present Invention is to
render parts of the apparatus advantageously applicable for turning over ingots, or
blooms, or masses of metal in different directions.
In carrying out the Invention there is provided at each part of the rolling machinery
where the metal masses have to be moved across or turned over, a truck with wheels
on rails, or a frame sliding on guides, which is arranged to be moved across by means
of an hydraulic cylinder. Each truck or sliding frame has on it one or more central

page_text: tables or supports to each of which there are hinged or jointed two plates or leaves,
one at each side, and each connected by a link or links to the ram of an hydraulic
cylinder on the truck or sliding frame, in a vertical or other suitable position. The
slide plates or leaves can be turned outwards from a vertical position into a horizontal
position; and they can also be turned inwards to some extent.
And in order that the said Invention and the manner of performing the same may
be properly understood we hereunto append three sheets of explanatory drawings to
be hereinafter referred to, and representing apparatus as constructed with our present
improvements.
Figure, 1, on sheet, 1, of the drawings is a plan of the apparatus; and figures, 2,
and 3, on sheets, 2, and 3, are elevations as at right angles to each other. In these
drawings the same reference numerals are used to mark the same or like parts wherever
they are repeated.
In the example shown in the drawings a kind of double truck is used con-
sisting of two parts, 4, each on four wheels, 5, arranged to run on guide rails not
fully shown, but in practice arranged to allow of the truck moving across parallel
to the rolls of the rolling mill. The two part trucks, 4, are connected together
by a middle casting, 6, to which is jointed the piston rod, 7, of an hydraulic
cylinder, 8, employed for moving the double truck into different positions as
required. Each part truck, 4, is formed with a middle raised part or table, 9,
which has jointed to it at opposite sides two plates or leaves, 10, and these plates
or leaves, 10, are connected by links, 11, to the rams or piston rods, 12, of two
vertical hydraulic cylinders, 13, formed on each part truck. These hydraulic
cylinders, 13, are double-acting their pistons being raised by water or other liquid
under pressure being admitted by pipes, 14, to their lower ends and acting on the
entire bottom areas of their pistons, whilst they are depressed when required by
the liquid acting on the smaller annular area on the upper sides of their pistons.
By preference valves are applied only in connection with the lower ends of the
cylinders, pressure always acting in the upper ends through pipes, 15. Above the
main hydraulic cylinder, 8, for moving the truck there is a telescopic arrangement
of pipes for leading the liquid to and from the truck cylinders, 13, and comprising
three fixed pipes, 16, 17, 18, with stuffing boxes at the ends nearer the truck
and with pipes, 19, 20, 21, working through the stuffing boxes and attached to
the middle casting, 6, of the truck. One pipe, 19, communicates by the pipes, 15,
with the upper ends of the truck cylinders, 13; a second pipe, 20, communicates by
pipes, 14, with the lower ends of two of the truck cylinders, and the third pipe, 21,
similarly communicates by pipes, 14, with the lower ends of the other truck cylinders.
The further ends of the fixed pipes, 16, 17, 18, communicate with the controlling valve
apparatus, which is not shown, but which may be of any suitable kind in use in con-
nection with hydraulic cylinders.
Each jointed plate or leaf, 10, can by means of its hydraulic cylinder, 13, be placed
in a horizontal position as shown at the left-hand side of the truck in figure, 2; or it
can be placed in a vertical position; or again it may be set or turned inwards as
shown at the right-hand side of the truck in figure, 2. With the apparatus as described
and capable of operating in the modes indicated a mass of metal can be turned on
edge from a horizontal position or vice versa, or completely over.
If found to be more convenient in any case steam or compressed air may be used
instead of a liquid in the cylinders these being made of sizes to suit the pressure
employed.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improved combination of parts of apparatus for moving metals in connection
with rolling mills, the said parts being arranged and operating substantially as herein-
before desceribed

page_text: 2. On a truck for moving metals in connection with a rolling mill, combining one
or more middle parts formed or fixed on the truck with leaves or plates jointed to both
sides of such middle parts and movable by separate hydraulic cylinders on the truck
substantially as and for the purposes hereinbefore described.
Dated this Twentieth day of November 1889.
