Improvements in Apparatus for Turning and otherwise Manipulating
and Supporting Ingots and other Forms of Steel or Iron.
I, ARTHUR SEDDON 63 Ellesmere Road, Sheffield in the County of York Engineer
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of apparatus for carrying
turning and otherwise manipulating Ingots and other heavy forms of steel, Iron,
or iron and steel in combination, during the process of heating, forging, pressing,
or other like operation, the object being to enable the workmen to have perfect
control over, and easily turn or otherwise manipulate heavy ingots or other large
masses or forms of metal as desired.
It consists of an arrangement of mechanism and a sling chain which is equally well
adapted to and may be supported or carried by a "Traveller" or by a Jib Crane and
which may be described as follows-
A strong crosshead is supported by chains from the crane in such a manner that it
can be raised or lowered, and to this crosshead the apparatus is secured by means of a
strong vertical pin which passes through the crosshead and is capable of being
revolved and secured in position as required. From the lower and enlarged part of
the crosshead two side plates depend supporting between them a flanged chain pulley
upon which the sling chain is carried.
Upon the vertical pin, but not secured thereto, and immediately under the cross-
head a pair of connected wheels (or a double solid wheel) of any suitable diameters
are placed one being underneath the other. A corresponding wheel carried by the
bottom end of a vertical shaft is geared into the upper one of the said two wheels or
the upper part of the solid double wheel and is driven by means of a worm wheel
and a worm suitably carried and driven by shafting connected with the engine or
other power. This vertical shaft is provided with two or more universal or ball
joints to enable the shaft to give or accommodate itself to the various positions
assumed by the apparatus as it is drawn from one side to the other during the progress
of the work.
The lower of the two wheels before mentioned as being on the vertical pin,
gears into another wheel upon a short vertical shaft carried by a projection upon
one of the side plates that carry the chain pulley, this last mentioned wheel can be
dropped out of gear by any suitable device, when it is desired to rotate the vertical
pin and the sling chain.
On the lower end of the short vertical shaft under the projection I fix a bevil
pinion working in gear with a bevil wheel which is secured to one end of the axle
carrying the chain pulley.
The action is as follows, when it is desired to turn the ingot or other form of
metal in the sling chain in either direction, the worm shaft is caused to revolve
in accordance therewith, this action causes the vertical shaft to revolve, the motion
is transmitted through the train of wheels (which I prefer to arrange in such
diameters as to gain power) then through the bevil pinion and wheel, to the axle upon
which the chain pulley is fixed, causing it to revolve, and to roll over the ingot which
is suspended in the loop of the chain.
To enable the vertical centre pin to revolve easily I adapt a circle of antifriction
roller bearings let into an annular recess under the head of the vertical pin, and upon
which the said head supported.
The apparatus is secured in certain pre-arranged positions by means of a spring
oint which enters one of a number of recesses formed in the side of the pin, and

to enable it to be turned to another position.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Turning and otherwise Manipulating
and Supporting Ingots and other Forms of Steel or Iron.
I, ARTHUR SEDDON 63, Ellesmere Road, Sheffield in the County of York,
Engineer 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 :-
This invention relates to improvements in the construction of apparatus for
carrying, turning, and otherwise manipulating Ingots, and other heavy forms of
steel, Iron or Iron and steel in combination, during the process of heating, forging,
pressing or other similar operations; the object being to enable the workmen to
have perfect control over the said Ingots or other masses of material, and to facilitate
the operations.
And to enable my invention to be fully understood, I have annexed drawings of an
apparatus made according to the said invention in its chief details.
Fig. 1, is an elevation of an apparatus made according to my invention.
Fig. 2, plan of driving-shaft connection.
Fig. 3, section of spring catch.
Fig. 4, plan of antifriction support.
Fig. 5, side elevation of apparatus.
Fig. 6, driving-shaft connection.
This apparatus may be carried by a traveller" or by a Jib Crane, or other like
means, and may be modified to suit the lifting mechanism of such cranes.
A strong crosshead A, the form of which may be varied, is supported by chains
from the traveller or crane in such a manner that it can be raised or lowered by the
ordinary movements of the crane, and to this crosshead the rest of the apparatus
is secured by means of a strong vertical pin B, which passes through the cross-
head A, and is capable of being revolved, and also secured in position as required.
From the lower and enlarged part of the pin B, two side-plates or arms Ü, depend,
and support between them a flanged chain-pulley D, upon which the sling chain E is
carried.
Upon the vertical pin B, but not secured thereto, and immediately under the
crosshead A a pair of connected toothed wheels, or a solid double wheel F, of any
suitable diameters, are placed, as shown. A corresponding wheel G, carried by
the bottom end of a vertical shaft H, is geared into the upper wheel F, and is
caused to revolve by means of a worm and worm-wheel. I and J, Figs. 2 and 6-
driven by the horizontal driving-shaft K, or an equivalent arrangement under the
control of the crane attendant.
1 propose to provide this vertical shaft with one or more universal, or ball-joints,
(not shown in the drawings) placed in any suitable position so as to enable the shaft
to accommodate itself to the varying positions assumed by the apparatus, as it is
drawn from one side to the other during the progress of working.
The lower wheel of those marked F, gears into another wheel L, mounted upon
a short vertical shaft M, carried upon, and revolving in a bearing upon one of the side
plates C; this wheel L, can be raised into gear, or dropped out of gear with its fellow
wheel, by any suitable device, such as an eccentric and slide N, as is well understood.
This action is to permit the apparatus to be rotated, or turned round without causing
the ingot, or other object in the sling chain-to-revolve.

page_text: On the lower end of the short vertical shaft M, and under the bearing, I fix a bevel
pinion P, in gear with a bevel-wheel Q, which is secured upon one end of the axle R,
of the chain pulley D.
The action of the apparatus is as follows: When it is desired to turn the ingot or
other mass of metal suspended in the loop of the sling chain, in either direction, tho
shaft K is caused to revolve in accordance therewith, this action transmitted through
the worm and wormwheel I and J, causes the vertical shaft H to revolve, the train of
wheels, the short vertical shaft M, and bevel pinion P are set in motion, causing
the bovel-wheel Q and the flange wheel D to revolve slowly, and thus to roll over,
the ingot or other object suspended in the loop of the chain E.
To avoid unnecessary friction and to enable the supporting pin with its load to be
easily revolved, I use a circle of antifriction roller bearings let into an annular recess
under the head of the vertical pin, and upon which the head is supported; this is
shown in plan in Fig. 4.
The apparatus may be secured in certain pre-arranged positions by means of a
spring glut shown in Fig. 3, which is shown in position in Fig. 1 at S. The glut or
bolt is arranged to enter one of a number of holes or recesses formed in the pin B,
and can be withdrawn by the attendant whenever it is desired to release the apparatus
to enable it to be turned to another position.
Details which have not been described may be of any approved description; and
I do not limit my claims hereinafter stated to any mechanical details which are not
essential to the working of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1-In an apparatus for supporting and rotating ingots and other masses of metal,
the arrangement and combination of the several parts constituting the said apparatus,
substantially as herein before described, and illustrated.
2-In an apparatus for turning ingots and other masses of metal, the combination
of a Flanged-pulley D, arms C, bevel wheel Q, and pinion P, wheels F, G, L,
supporting pin B, and Crosshead A, arranged and working together substantially as
herein before described and, shown in the drawings.
