Year: 1873

page_text: LETTERS PATENT to Joseph Coley, Forge Manager, John George
Robson, Roll Turner, and John Price, Forge Manager, all of
Darlington, in the County of Durham, for the Invention of "IM-
PROVED APPARATUS TO BE USED IN CONNECTION WITH ROTARY PUDDLING
FURNACES."
PROVISIONAL SPECIFICATION left by the said Joseph Coley, John
George Robson, and John Price at the Office of the Commissioners
of Patents, with their Petition, on the 22nd July 1873.
We, JOSEPH COLEY, Forge Manager, JOHN GEORGE ROBSON, Roll
Turner, and JOHN PRICE, Forge Manager, all of Darlington, in the
County of Durham, do hereby declare the nature of the said Invention
for "IMPROVED APPARATUS TO BE USED IN CONNECTION WITH ROTARY PUDDLING
FURNACES," to be as follows:-
:-
This Invention consists in the addition of blades or cutters to the
rotary squeezers employed for compressing the "balls" from rotary
puddling furnaces whereby the compressing or squeezing and cutting or

page_text: dividing the "balls" into pieces of suitable size for the rolls are per-
formed in one operation, and also in the construction of a lift or clevator
for the purpose of lifting the "ball" to be operated upon into the
squeezer.
The squeezer consists of a revolving cylinder mounted on a horizontal
axis, and which rotates within a cast-iron case having an eccentrically
curved inner surface, so that the distance between the revolving cylinder
and the case gradually lessens from the point at which the rough "ball”
from the puddling furnace is introduced into the squeezer to the point
at which the compressed "ball" leaves the apparatus, so that by the
motion of the revolving cylinder the "ball" is carried downwards and
gradually compressed between the revolving cylinder and the eccen-
trically curved surface of the case until it is reduced to a diameter
suitable for the rolling mills. As the "balls" which are produced by
the rotary puddling furnaces after they leave the squeezer are of too great
a length for the rolls, it has hitherto been the practice to carry the com-
pressed "balls" from the squeezer to a hammer by which they are divided
into "balls" of suitable lengths, it has then been found necessary.
to take them to a reheating furnace before taking them to the rolls.
According to this Invention instead of continuing the cast-iron case
with the compressing surface under the revolving cylinder to the
point of exit as at present, a portion of it is removed, and a block
carrying suitable blades or cutters is placed in lieu thereof, so that when
the "ball" has been compressed to as small a diameter as possible it is
divided into suitable lengths for the rolls by being pressed against the
blades or cutters on the block by the revolving cylinder, thus obviating
the necessity of taking the "balls" to the hammer to be divided, and
then to the reheating furnace, as the "balls" as they are delivered on
to the "bogies" from the squeezer constructed with the blades or
cutters, according to this Invention, are ready to be taken direct to the
rolling mills.
The block carrying the blades or cutters is fixed in the bed of the
"squeezer," in such a manner as to be readily removed for the purpose of
being cleaned or repaired, the blades or cutters being so arranged on the
block as to be readily removed therefrom, should they become damaged,
and fresh ones substituted therefor.
It will be readily understood by persons conversant with such matters
that the blades or cutters can be placed at any desired distance from

page_text: one another, and one block carrying a greater or lesser number of blade
or cutters substituted for another so as to produce "balls" of greater or
lesser length as may be desired.
For the purpose of lifting or elevating the rough "ball" into the
squeezer, an arm or lever is fixed at each end of an iron shaft which
passes through the axle of the revolving cylinder, the axle being made
hollow for that purpose. These arms or levers carry a cradle between
them, and into which cradle the "ball" is placed when it comes from
the puddling furnace. The levers or arms are then raised by means of
a small steam cylinder or other suitable means until the cradle reaches
the top of the squeezer, when a small bar fixed to the cradle comes in
contact with a catch placed upon the framework of the squeezer for that
purpose, thereby tilting the cradle so as to allow the "ball" to slide
therefrom into the squeezer.
It will be readily understood that a lift or elevator constructed as
above is applicable to all rotary squeezers working on a horizontal axis,
and whether provided with the blades or cutters, as herein-before
described or not.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Coley, John George Robson and John
Price in the Great Seal Patent Office on the 21st January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
COLEY, Forge Manager, JOHN GEORGE ROBSON, Roll Turner, and JOHN
PRICE, Forge Manager, all of Darlington, in the County of Durham,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of July, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of the reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Joseph Coley, John George Robson,
and John Price, Her special licence that we, the said Joseph Coley, John
George Robson, and John Price, our executors, administrators, and
assigns, or such others as we, the said Joseph Coley, John George
Robson, and John Price, our executors, administrators, and -assigns,

page_text: 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVED APPARATUS TO BE USED IN CONNECTION
WITH ROTARY PUDDLING FURNACES," upon the condition (amongst others,)
that we, the said Joseph Coley, John George Robson, and John Price,
our executors or administrators, by an instrument in writing under our,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, 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 we, the said Joseph Coley, John George
Robson, and John Price, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following state-
ment, reference being had to the Drawings hereunto annexed, and to
the figures and letters marked thereon, that is to say :-
Our said Invention consists, firstly, in the addition of blades or cutters
to the rotary squeezers employed for compressing the "balls" from
rotary puddling furnaces whereby the compressing or squeezing and
cutting or dividing the "balls" into pieces of suitable size for the rolls
are performed in one operation, and secondly, in the construction of a
lift or elevator for the purpose of lifting the "ball" to be operated upon
into the squeezer.
The squeezer consists of a revolving cylinder mounted on a horizontal
axis, and which rotates within a cast-iron case having an eccentrically
curved inner surface, so that the distance between the revolving cylinder
and the case gradually lessens from the point at which the rough "ball”
from the puddling furnace is introduced into the squeezer to the point
. at which the compressed ball or "bloom" leaves the apparatus, so that
by the motion of revolving cylinder the "ball" is carried downwards
and gradually compressed between the revolving cylinder and the eccen-
trically curved surface of the case until it is reduced to a diameter
suitable for the rolling mills. As the "balls" or blooms" which are
produced by the rotary puddling furnaces after they leave the squeezer
"

page_text: "
are of too great a length for the rolls, it has hitherto been the practice
to carry the compressed " " balls or "blooms" from the squeezer to a
bammer, by which they are divided into "blooms" of suitable length.
It has then been found necessary to take them to a reheating furnace
before taking them to the rolls.
According to this Invention instead of continuing the compressing
surface of the cast-iron case under the revolving cylinder to the point of
exit as at present, a portion of it is removed, and a block carrying
suitable blades or cutters is placed in lieu thereof, so that when the
"ball" has been compressed to as small a diameter as desired it is
divided into suitable lengths for the rolls by being pressed against the
blades or cutters on the block by the revolving cylinder, thus obviating
the necessity of taking the "blooms" to the hammer to be divided, and
then to the reheating furnace, as the "blooms" as they are delivered on
to the "bogies" from the squeezer constructed with the blades or
cutters according to this Invention are ready to be taken direct to the
rolling mills.

The block carrying the blades or cutters is fixed in the bed of the
squeezer, in such a manner as to be easily removed for the purpose of
being cleaned or repaired, or of being replaced by another, the blades or
cutters being so arranged on the block as to be readily removed and
fresh ones substituted therefor.
It will be well understood by persons conversant with such matters
that the blades or cutters can be placed at any desired distance from one
another, and one block carrying a greater or lesser number of blades or
cutters substituted for another so as to produce "balls or "blooms"
of greater or lesser length as may be desired.
"
For the purpose of lifting or elevating the rough "ball" into the
squeezer, an arm or lever is fixed at each end of an iron shaft which
passes through the axle of the revolving cylinder, the axle being made
hollow for that purpose. These arms or levers carry a cradle between.
them, and into which cradle the "ball" is placed when it comes from
the puddling furnace. The levers or arms are then raised by means of
a small steam cylinder or other suitable means until the cradle reaches
the top of the squeezer, when a small bar fixed to the cradle comes in
contact with a catch placed upon the framework of the squeezer for that
purpose, thereby tilting the cradle so as to allow the "ball" to slide
therefrom into the squeezer..

page_text: It will be readily understood that a lift or elevator constructed as
above described is applicable to all rotary squeezers where it is desired
to raise the "ball" to the top thereof, and whether provided with blades
or cutters, as herein-before described or not.
We will now proceed to refer to the accompanying Drawings in which
Figure 1 is a side elevation of a squeezer provided with the blades or
cutters, and a lift or elevator, as herein-before described, Figure 2 being
a transverse section through the same; Figure 3, a plan partly in
section; and Figure 4 is a half front and half back elevation of the
same. The same letters of reference indicate similar parts in the several
Figures.
A is the cast-iron case with the eccentrically curved inner surface B;
Cis the revolving cylinder, and a is the "ball" on the cradle of the lift;
a', the "ball" on its transit through the squeezer; and a² the "ball"
whilst being cut or divided by the blades or cutters E; D is the block
carrying the blades or cutters E for the purpose of cutting or dividing
the "balls," & being a channel left between the block D and the end of
the eccentrically curved surface B for the escape of any slag or scale'
that may come from the "ball" whilst under treatment, and also of the
water used for keeping the blades or cutters cool whilst being used.
F, F, are the arms or levers fixed at each end of the iron shaft f which
passes through the hollow axle c of the revolving cylinder C; G is the
cradle into which the "ball" is placed, and which is carried between
the arms or levers F, F; H, being the small bar which comes into
contact with the catch for the purpose of tilting the cradle G, as
herein-before mentioned.
As a modification of the first part of this Invention, and to render it
capable of being used to divide "blooms" compressed by Danks's or
similar squeezers, which consist of an eccentric cam rotating above two
rollers, and upon which rollers the "ball" is placed, so that as the
eccentric cam rotates it gradually compresses the "ball," or by any
other form of rotary squeezer not constructed as herein-before described,
a revolving cylinder similar to that herein-before mentioned and
mounted in suitable bearings carried by a bed plate, and into which
bed plate the block carrying the blades or cutters is fixed, is, according
to this Invention, placed in the rear of the squeezer, so that when the
"bloom" is discharged therefrom it passes between the revolving.

page_text: cylinder and the block carrying the blades or cutters, and is thereby
divided into suitable lengths for the rolls.
Having thus declared and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we would observe
in conclusion that what we consider novel and original, and therefore
claim as constituting the Invention secured to us by the herein-before
in part recited Letters Patent are,-
First. The combination and use of blades or cutters with the squeezers
in the manner and for the purposes herein-before set forth and described,
or any mere modifications thereof.
And, secondly. The construction of a lift or elevator to be used in
connection with rotary squeezers, as and for the purposes herein-before
set forth and described, or any mere modifications thereof.
In witness whereof, we, the said Joseph Coley, John George
Robson, and John Price, have hereunto set 'our hands and seals,
this Seventeenth day of January, in the year of our Lord One
thousand eight hundred and seventy-four.
