for the Invention of "IMPROVEMENTS IN MACHINES FOR SQUEEZING OR

Sealed the 28th March 1873, and dated the 9th October 1872.
PROVISIONAL SPECIFICATION left by the said Samuel Danks at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1872.
I, SAMUEL DANKS, of Cincinnati, Ohio, United States of America,
now of No. 8, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINES FOR SQUEEZING
OR COMPRESSING BALLS AND BLOOMS OF IRON OR STEEL, AND IN EJECTING APPARATUS
FOR SUCH MACHINES," to be as follows:-
My said Invention relates partly to the combination of a horizontal
steam ram with the rolls and cam of a squeezer, and partly to an ejector
.

page_text: of novel construction to be employed with my improved squeezing
machines, or with other squeezing machines.
The said steam ram is placed at one end of the squeezing rolls, and is
so arranged that its head or hammer will strike the end of the ball or
bloom lying on the rolls. The cylinder of the said ram has a slide valve
connected with a hand lever, whereby the admission and exhaust of the
steam are regulated to drive forward and withdraw the hammer. In the
cylinder at the back of the piston I place a diaphragm, behind which
steam is admitted to form a cushion, which prevents the piston's striking
the end of the cylinder in its return or backward movement.
My improved ejecting apparatus is designed to effect the removal of
the balls or blooms from the squeezer in a more convenient and
expeditious manner than heretofore. This ejecting apparatus is formed
of a bar of iron or other suitable metal which has a straight portion
shaped to lie between the two rolls at or near the centre thereof, and
under the ball or bloom resting on the said rolls. From this straight
portion of the ejector extend two side pieces which are curved to fit and
rest upon two necks formed at the ends of one of the squeezing rollers.
At one side the said lifter is provided with a lever extended into any
convenient position. By means of this lever the ejector can be
manipulated to raise the ball or bloom from between the rolls into such
a position that it will roll upon and over one of the said rolls, and be
thereby ejected from the squeezer.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Danks in the Great Seal Patent Office, on 2
the 9th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
DANKS, of Cincinnati, Ohio, United States of America, now of No. 8,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Ninth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Samuel Danks, Her special

page_text: licence that I, the said Samuel Danks, my executors, administrators,
and assigns, or such others as I, the said Samuel Danks, my executors,
administrators, and assigns, 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, usc, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN MACHINES FOR SQUEEZING OR COMPRESSING BALLS AND BLOOMS OF IRON OR
STEEL, AND IN EJECTING APPARATUS FOR SUCH MACHINES," upon the condition
(amongst others) that I, the said Samuel Danks, my executors or
administrators, by an instrument in writing under my, 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 I, the said Samuel Danks, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement, reference being bad to the accompanying
Drawing forming a part of this Specification :-
My said Invention relates partly to the combination of a horizontal
steam ram with the rolls and cam of a squeezer, and partly to an ejector
of novel construction, to be employed with my improved squeezing
machines or with other squeezing machinery.
The said steam ram is placed at one end of the squeezing rolls, and is
so arranged that its head or hammer will strike the end of the ball or
bloom lying on the rolls. The cylinder of the said ram has a slide valve
connected with a hand lever, whereby the admission and exhaust of the
steam are regulated to drive forward and withdraw the hammer. In the
cylinder at the back of the piston I place a diaphragm, behind which
steam is admitted to form a cushion which prevents the piston's striking
the end of the cylinder in its return or backward movement.
My improved ejecting apparatus is designed to effect the removal of
the balls or blooms from the squeezer in a more convenient and
expeditious manner than heretofore. The ejector or lifter is formed of a
bar of iron or other suitable metal which has a straight portion shaped

page_text: to lie between the two rolls at or near the centre thereof, and under the
ball or bloom resting on the said rolls. From this straight portion of
the lifter extend two side pieces which are curved to fit and rest upon
two necks formed at the ends of one of the squeezing rolls. At one
side the said lifter is provided with a lever extended into any convenient 5
nosition
Figure 1 is a vertical longitudinal section of my improved machine;
Figure 2 is a transverse vertical section on the line x, x, Figure 1;
Figure 3 is a plan of the squeezing rolls and bloom ejector; Figure 4 is
an end elevation of the same. Like letters indicate the same parts
throughout the Drawing.
The said machino has two strong uprights or standards a of cast iron
or other suitable material which are firmly secured upon the beams or
girders b c is the aforesaid cam mounted on the shaft c' which is fitted
to turn in the bearings a' at the top of the said standards; d, d, are the
rolls whose journals are supported and turn freely in suitable bearings
at the base of the said standards. The cam shaft c' and the rolls are
geared in connection with the driving shaft e, and are thereby caused to
rotate in the proper directions.
Figure 1 shews clearly the arrangement of the aforesaid steam ram in
combination with the cam and rolls; is the cylinder of the steam
ram; g is the piston, and g' the piston rod to whose outer end is secured
the hammer or bumper h; i is the slide valve which is connected by the
rod to the lever /, whereby the said valvo is adjusted to regulate the
admission and exhaust of the steam used in the said cylinder for driving
the said hammer forward and withdrawing the same; m is the aforesaid
diaphragm which lies between the piston and the end of the cylinder,
and forms a cushion or buffer for the said piston if the backward move-
ment of the same should be too rapid or forcible. As the ball or
bloom is squeezed between the cam and rolls it is hammered and
compressed endwise by the said ram, and is thereby rapidly worked into
the required form and condition.
The manner of using my improved apparatus for ejecting the blooms
from the squeezer is clearly illustrated in Figures 3 and 4. The ejector
or lifter is an iron bar which is formed at n' to fit and rest upon the
