Year: 1857

page_text: LETTERS PATENT to George Walter Dyson, Steel Roller, Tinsley,
near Sheffield, in the County of York, for the Invention of "TILTING
IRON AND STEEL, OR ANY OTHER MALLEABLE SUBSTANCE BY PERPENDICULAR
MOTION."
Sealed the 11th August 1857, and dated the 5th March 1857.
PROVISIONAL SPECIFICATION left by the said George Walter Dyson at
the Office of the Commissioners' of Patents, with his Petition, on the
5th March 1857.
I, GEORGE WALTER DYSON, Steel Roller, Tinsley, near Sheffield, in
the County of York, do hereby declare the nature of the said. Invention
for "TILTING IRON AND STEEL, OR ANY OTHER MALLEABLE SUBSTANCE BY PER-
PENDICULAR MOTION," to. be as follows:-
It is worked by compressed steam in a cylinder errected on framework;
connected to the piston is a shaft with the hammer attached, working
perpendicular by means of an arm case revolving round the upright shaft,
with arms so constructed as to raze the upright shaft by means of two brays
projecting out at the two oppisite sides of the upright shaft, the brays
droping off at the extremity of the arms, whereby the compressed steam
forces down the piston, causing the stroke. The arm case revolves by means
of two bevil wheels,. one: connected to the arın case, and the other on a
horizontal driving shaft.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WALTER DYSON, of Tinsley, near Sheffield, in the County of York, Steel
Roller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Walter Dyson, Her special licence that I, the said George Walter
Dyson, my executors, administrators, and assigns, or such others as I, the
said George Walter Dyson, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "TILTING IRON
AND STEEL, OR ANY OTHER MALEABLE SUBSTANCE BY PERPENDICULAR MOTION,"
upon the condition, amongst others, that I, the said George Walter Dyson,
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 George Walter Dyson, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the annexed Drawings, that is to say:
The object of these improvements are to simplify and reduce the present
mode of constructing tilts for tilting iron, steel, or any other maleable
substance.
First, to effect this compressed steam is used to increase the momentum of
the falling bammer or upright shaft with projecting arms, which is raised by
circular inclined arms revolving and passing under the brays or steelings,
which are dovetailed or otherwise into the projecting arms, the hammer or
upright shaft falling at the extremity of the lift of the circular inclined arms,
thereby causing the stroke. The hammer or upright shaft is prevented from

page_text: revolving round with the motion of the circular inclined arms by means of the
projecting arms working perpendicular into slides at each end, the slides being
supported and bolted on to the framework. The circular inclined arms are
bolted, dovetailed, or otherwise, on to an arm case, which revolves by means of a
bevel spur wheel, which is keyed on to the arm case, and driven by means of
a bevel spur pinion on a horizontal driving shaft, with fly wheel and loose and
fast pulleys for the driving band, from an engine or any other prime mover.
The hammer or upright shaft works perpendicular through the centre of the
revolving circular inclined arms, having at the lower end the top hammer
face or other tools dovetailed or otherwise fastened in, which strike upon tho
lower face or anvil, which is dovetailed or otherwise into a large cast-iron
block bedded on a wood foundation. The steam is compressed in a cylinder
by means of the bammer or upright shaft rising perpendicular, and coming in
contact with a piston which rests upon a seat formed in the cylinder, as shewn
in Figure 1. The full pressure of steam, being always upon the piston, acts
as a spring upon the falling hammer or upright shaft. The piston is raised
or lowered with iron rings, compressing the steam various distances according
to the weight of stroke required.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim as my
Invention is,
First, the mode of raising the hammer or upright shaft by means of
revolving circular inclined arms, as herein-before described.
Second, the mode of applying the steam with the loose piston, acting as a
spring, to increase the momentum of the falling hammer or upright shaft, as
herein-before described.
In witness whereof, I, the said George Walter Dyson, have hereunto set
my band and seal, this Third day of September, One thousand eight
hundred and fifty-seven.
