IMPROVEMENTS IN APPARATUS FOR REMOVING INGOTS FROM MOULDS
Year: 1882

page_text: PROVISIONAL SPECIFICATION left by the said Thomas Hampton at the
Office of the Commissioners of Patents on the 28th June 1882.
THOMAS HAMPTON of Sheffield, Steel Manufacturer" IMPROVEMENTS IN
APPARATUS FOR REMOVING INGOTS FROM MOULDS."
This invention relates to that class of apparatus employed for removing from
their moulds, ingots which stick therein, by means of a plunger or pushing head
and a lever attached to a chain connected or hooked to the arm of the crane
Several forms and arrangements of these have been suggested by others, but so far
as I am aware, they have all been so constructed that the plunger is forced against
the interior side of the mould whereby much power is lost and the operation of
the parts is unsatisfactory This invention consists of the arrangement and
combination of parts as hereinafter described whereby the above defects are
obviated The ingot 'moulds are supplied with two opposite loops or rings at the
top and to these are hooked short arms pivoted on two separate levers, which in
turn meet and are pivoted at their inner extremities at a point directly over the
mould At this point is also connected a rod or arm carrying the plunger or
pushing head
To the outer extremities of the levers is hooked a chain or chains
which at a point directly over the mould is or are suitably connected to the arm
of the crane
Where a long thrust or play of the plunger or pushing head is desired the two
levers may be so pivotted that when the short arms are attached to the mould and
the plunger is resting on the top of the ingot the said levers will be in a reversed
V shaped position
When the apparatus is connected as described and the arm of the crane is
raised the outer ends of the levers are drawn upward and the inner pivotted ends
with the attached plunger or pushing head is pushed down and will exert a
pressure on the ingot to force it from its mould up to the combined weight of the
ingot and mould

APPARATUS FOR REMOVING INGOTS FROM MOULDS"
"IMPROVEMENTS IN
This Invention relates to that class of apparatus employed for removing from
their moulds, ingots which stick therein, by means of a plunger or pushing head
and a lever attached to a chain connected or hooked to the arm of the crane.
Several forms and arrangements of these have been suggested by others but so far
as I am aware, they have all been so constructed that the plunger is forced against
the interior side of the mould whereby much power is lost and the operation of
the parts is unsatisfactory This invention consists of the arrangement and
combination of parts as hereinafter described whereby the above defects are
obviated Reference is also made to the accompanying Drawings which form part
of this Specification and in which Fig 1 represents the pushing apparatus as
resting on the top of an ingot, while in its mould, the latter being shown in section
Fig 2 represents the ingot as being partly pushed from its mould. Figs 3, 4 and 5
show in enlarged views details of the apparatus The ingot moulds A A aro
supplied with two opposite loops or rings a a at the top and to these are hooked
short arms b. b. pivoted on two separate levers B. B which in turn meet and are
pivoted at their inner extremities c at a point directly over the mould At this
point is also connected a rod or arm C carrying the plunger or pushing head D
To the outer extremities of the levers B. B is booked a chain or chains E. E
which at a point e directly over the mould is or are suitably connected to the arın
of the crane. Where a long thrust or play of the plunger or pushing head D is
desired, the two levers B. B may be so pivoted that when the short arms b. b. are
attached to the mould loops or rings a. a. and the plunger D is resting on the top
of the ingot the said levers will be in a slightly reversed V shaped position as
shown in Fig 1 When the apparatus is connected as described and the arm of
the crane is raised, the outer ends of the levers B. B. are drawn upward, and the
inner pivoted ends with the attached plunger or pushing head is pushed down as
shown in Fig 2. The pressure exerted on the ingot to force it from its mould
will be equal to the combined weight of the ingot and the mould For ordinary
use I find that the levers B. B. may be about 2 feet 4 inches in length, 21 to
3 inches wide and to 1 inch in thickness
The slot for the pivot at c may be 23 x 14 inches and be placed at to 1 incli
from the end of the bar. A to 1 inch hole about 10 to 12 inches from the inner
end of the lever will suffice for the attachment of the hurt arms b. b. which may
conveniently be of the form shown in Fig 4 and made with 1 to 2 inch faces
and of an inch thick on each side of the lover
The hook itself may be 14 inch diameter at its shank while the distance from
the centre of the bolt hole at the top of arm b, to the lowest part of the hook is
about 8 inches The pushing head D may be about 5 inches in diameter, and be
carried by a 1 inch round arm C preferably made as represented in Fig 5 with
2 inch face, to plates which are about 1 inch thick, on either side of the levers
The length of the arm O from centre of pivot hole to pushing head may be
advantageously about 1 foot 8 inches

page_text: Having thus described my Invention, and how the same may be carried into
effect What I claim and desire to secure by Letters Patent is
The improvements in apparatus for removing ingots from their moulds, all
substantially as and for the purposes set forth and described
In Witness whereof I the said Thomas Hampton have hereunto set my
hand and seal this twenty second day of December in the year of Our
Lord one thousand eight hundred and eighty two.
