with Rolling Mills for Turning Over and Transferring Ingots
and Blooms.
I, EDWARD WINDSOR RICHARDS of Brackenhoe, Marton, Middlesbrough-on-Tees
in the county of York, Engineer, do hereby declare the nature of said invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR USE IN CONNECTION WITH
ROLLING MILLS FOR TURNING OVER AND TRANSFERRING INGOTS AND BLOOMS
to be as follows:―
"
My invention relates to machinery or apparatus used in connection with rolling
mills for turning over the ingots or blooms, and transferring or moving them into
position opposite a succeeding set of grooves. Although apparatus for these
purposes has been proposed to be used yet it is most usual to roll ingots and
blooms by the labour of workmen armed with tongs and bars. The weight of the
ingot to be rolled has, therefore, in such cases to be limited to the power of the
number of workmen who can be placed to command it. Moreover, this system of
rolling is slow, costly and dangerous to the workmen.
Now the object of my invention is to enable ingots of much greater weight
than can advantageously be manipulated by the ordinary process, to be readily
rolled, and at much less cost, and without the employment of workmen with tongs
and bara.
For this purpose I make use of a special arrangement of apparatus that I will
now describe, and which can with easy working valves be put into motion by two
men or youths so that the heaviest blooms can be rolled without it being necessary
to employ any workmen in front of or behind the rolls.
The machine comprises two pairs of hydraulic plungers or rams, placed one pair
opposite the other on one side of the rolling mill. The cylinders of each pair are
respectively one stationary and one able to oscillate in a vertical plane on trunnions.
The axes of the stationary cylinders are parallel with the axes of the feed rollers,
which are situate between them but at a lower level. Between these rollers, and
parallel thereto, are girders or rails, on which can travel two carriages, one attached
to the ram or plunger of each stationary cylinder.

convenient number, of arms or radii, the upper ends of which are connected by a
transverse shaft or bar and are operated simultaneously by the ram or plunger of
the corresponding oscillating cylinder. With this arrangement by admitting water
at the backs of the plungers of a pair of cylinders the plunger of the stationary one!
will move a bloom or an ingot laterally from groove to groove, and the plunger of
the corresponding oscillating cylinder will by its differential motion assist the other
in bringing into, and keeping the bloom or ingot in a vertical position for the
edging grooves of the rolls,

I, EDWARD WINDSOR RICHARDS, of Middlesbrough-on-Tees in the County of
York, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR USE IN CONNECTION WITH ROLLING
MILLS FOR TURNING OVER AND TRANSFERRING INGOTS AND BLOOMS," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
.
My invention relates to machinery or apparatus used in connection with rolling
mills for turning over the ingots or blooms and transferring or moving them into
position opposite a succeeding set of grooves. Although apparatus for these
purposes has been proposed to be used yet it is most usual to roll ingots and
blooms by the labour of workmen armed with tongs and bars. The weight of the
ingot to be rolled has therefore in such cases to be limited to the power of the
number of workmen who can be placed to command it. Moreover this systein of
rolling is slow, costly and dangerous to the workmen. Now the object of my
invention is to enable ingots of much greater weight than can advantageously be
manipulated by the ordinary process to be readily rolled, and at much loss cost,
and without the employment of workmen with tongs and bars. For this purpose
I make use of a special arrangement of apparatus that I will now describe and
which can with easy working valves be put into motion by two men or youths so
that the heaviest blooms can be rolled without it being necessary to employ any
workman in front of or behind the rolls.
The machine comprises two pairs of hydraulic pistons or rams, placed one pair
opposite the other on one side of the rolling mill. The cylinders of each pair are
respectively one stationary and one able to oscillate in a vertical plane on trunnions.
The axes of the stationary cylinders are parallel with the axes of the feed rollers,
which are situate between them, but at a lower level-Between these rollera and
parallel thereto are girders or rails on which can travel two carriages one attached
to the ram or piston of each stationary cylinder. At the front of each carriage aro
pivotted 'the lower ends, of three or other convenient number of arms or radii the
upper ends of which are connected by a transverse shaft or bar and are operated
simultaneously by the ram or plunger of the, corresponding oscillating cylinder.
With this arrangement by admitting water at the backs of the pistons of a pair of
cylinders the piston of the stationary one will move a bloom or an ingot laterally
from groove to groove, and the plunger of the corresponding oscillating cylinder
will by its differential motion assist the other in bringing into, and keeping the
bloom or ingot in a vertical position for the edging grooves of the rolls.
Referring to the accompanying sheet of drawings Fig. 1 is a plan and Fig. 2 an
elevation of apparatus according to my invention for turning and transferring
ingots, and blooms, and slabs during the operation of rolling. The apparatus is
shown in conjunction with a set of feeding rollers, but the rolls themselves are not

page_text: included in the figures. At each side of the feeding rollers there are mounted a
pair of hydraulic cylinders A. A'. to which water under pressure can be admitted
and from which it can be exhausted by suitable valves under the control of a
workman. The lower cylinder A is stationary, while the upper A' is carried in
trunnions and can oscillate in a vertical plane. In each cylinder there works a
piston or plunger B or B¹. The lower of these, B, is connected directly to a
carriage C travelling on rails or girders D. D running parallel to the feed rollers,
while the upper piston B' is coupled to the same carriage by the three links or
arms E. E, and the stay F. These three arms are likewise keyed on to the weigh
shaft G. When the pressure water is admitted to the rear ends of either pair of
cylinders A, A, the respective rams or pistons B. B' will move outwards pushing
before them. the carriage C and the arms or links E. By varying the admission to
the two cylinders the rates of motion of the rams can be regulated and the
arms E. E made to advance at the upper end more or less rapidly than the carriage,
and thus assume an inclined attitude either inwardly or outwardly. Thus the
ingot may be either pushed along parallel to the rollers or it may be tipped over
either way. By manipulating both sets of cylinders an ingot or bloom may be
grasped and turned as if in a pair of tongs, and set on edge or side opposite any
part of the rolls.
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
.
- !
1. The use for moving and transferring ingots and blooms during the operation
of rolling, of an arm or a set of arms connected directly at each end to a hydraulic
ram or piston, and so arranged that the two ends can be moved independently of
each other substantially as described.
2. The use in connexion with the feeding rollers of a rolling mill for moving
and transferring ingots and blooms during the operation of rolling, of two arms
or sets of arms arranged at opposite sides of the said feeding rollers, each arm or
set of arms being connected directly at each end to a hydraulic ram or piston
substantially as described.
3. The improved apparatus for moving and transferring ingots and blooms
during the operation of rolling, constructed, arranged, and operating substantially
as described with reference to the drawings.
