Essex, and Andrew Whytock, of Little St. Andrew Street, St. Martin's
Lane, in the County of Middlesex, for the Invention of "IMPROVEMENTS
Sealed the 5th September 1862, and dated the 25th March 1862.
PROVISIONAL SPECIFICATION left by the said Edmund Morewood and
Andrew Whytock at the Office of the Commissioners of Patents,
with their Petition, on the 25th March 1862.
We, EDMUND MOREWOOD, of Stratford, in the County of Essex, and ANDREW
WHYTOCK, of Little St. Andrew Street, St. Martin's Lane, in the County of
Middlesex, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OR SHAPING OF IRON OR OTHER MATERIAL," to be as
follows:-
Our Invention consists in so arranging a roller or rollers having fluted,
undulated, or corrugated surfaces, that they shall make corresponding im-
pressions on the. sheets which may be passed widthways between, under, or
against such fluted, undulated, or corrugated roller or rollers without breaking
or tearing the sheet whilst lessening or reducing its superficial width by
making such flutes, corrugations, or indentions gradually, and for sometimes
curving the sheets at the same time.
The Invention also consists in causing sheets connected together into a

page_text: long or continuous sheet to pass widthways between, under, or against such
roller or rollers for the same purposes.
We prefer to pass the sheets to be thus corrugated between six pairs of
rollers in succession, the nip of each placed horizontally about 8 inches
behind that of the preceding pair, but this may be varied. If the sheet to
be corrugated will be reduced three inches in superficial width when finished, we
make the flütes or corrugations in the first pair of rollers so shallow that they
will reduce the superficial width of the sheet by only about half an inch
when it has received an impression. The next pair of rollers will reduce
it another half inch and deepen the flute correspondingly, and so on through the
.succession of pairs of rollers.
By placing the last one or two pairs of rollers a little above or a little
below the horizontal line we can give a corresponding curve to the corrugated
sheets. We sometimes make one of the flutes in the first and succeeding
pairs of rollers perfect so as to form at once such flute as will be impressed
on the finished sheet; this flute then acts" a holding point towards which
the rest of the sheet is drawn. We also c corrugate sheets by having a bed
fluted in the shape we desire to give to the sheet when finished. We place
such sheet to be corrugated on this bed. We then pass over it a weighted
carriage having one or more fluted. rollers attached to it, which by their revo-
lution press upon the sheet placed on the bed and form corrugations on it.
The fluted roller or rollers on their first passage over the surface of 'the sheet
press it down into, the flutes of the bed so far as to reduce it in width only
to a comparatively small extent, then by means of a lever or screw we
'depress the fluted roller so as to cause the sheet to be reduced another
small quantity and in so doing deepen the amount of flutes on the sheet
correspondingly.
:
Then we again screw or press down and cause the roller. again to travel
forward over the bed and so on till we have the required depth of flute.thus
gradually obtained without fracture or tear of the sheet. Or the bed may
be made moveable and the roller arranged simply to revolve on its axis..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmund. Morewood and Andrew Whytock in the Great
Seal Patent Office on the 24th September 1862.

Andrew Whytock, our 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 "IMPROVE->
MENTS IN THE MANUFACTURE OR SHAPING OF IRON OR OTHER MATERIAL," upon
the condition (amongst others) that we, the said Edmund Morewood and:
Andrew Whytock, our exécutors or administrators, by an instrument in writing:
under our or their hands and seals, or under the hands and seals of one of us or
them, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Edmund Morewood and Andrew Why-
tock, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, that is to say :-
Our Invention consists in so arranging a roller or rollers having fluted,.undu-
lated, or corrugated surfaces that they shall make corresponding impressions on:
the sheets which may be passed widthways between, under, or against such
fluted,. undulated, or corrugated roller or rollers, without breaking or !tearing,
the sheet whilst. lessening or reducing: its superficial width, by making, such:
flutes, corrugations, or indentations gradually, and sometimes curving the sheets.
at the same time.
;
- The Invention also consists in causing sheets connected together into a
long or continuous sheet to pass widthways between, under, or against such
roller or rollers for the same purposes. We prefer to pass the sheets to be thus:
corrugated between six pairs of rollers in succession, the nip of each placed
horizontally about eight inches behind that of the preceding pair; but this may
be varied. If the sheet to be corrugated will be reduced three inches, in,

page_text: :
superficial width when finished, we make the flutes or corrugations in the first
pair of rollers so shallow that they will reduce the superficial width of the
sheet by only about half an inch when it has received an impression. The
next pair of rollers will reduce it another half inch and deepen the flute.
correspondingly, and so on through the succession of pairs of rollers. By
placing the last one or two pairs of rollers a little above or a little below the
horizontal line we can give a corresponding curve to the corrugated sheets.
We sometimes make one of the flutes in the first and succeeding pairs of
rollers perfect, so as to form at once such. flute as will be impressed on the
finished sheet; this flute then acts as a holding point, towards which the rest
of the sheet is drawn. We also corrugate sheets by having a bed fluted in
the shape we desire to give to the sheet when finished; we place such sheet
to be corrugated on this bed, we then pass over it a weighted carriage having:
one or more fluted rollers attached to it, which by their revolution press upon.
the sheet placed on the bed and form corrugations on it. The fluted-roller or
rollers on their first passage over the surface of the sheet press it down into
the flutes of the bed, so far as to reduce it in width only to a comparatively
small extent, then by means of a lever or screw we depress the fluted roller,
so as to cause the sheet to be reduced. another small quantity, and in so doing
deepen the amount of flutes on the sheet correspondingly. Then we again
screw or press down and cause the roller again to travel forward over the
bed, and so on, till we have the required depth of flute thus gradually
obtained without fracture or tear of the sheet. Or the. bed may be made
moveable, and the roller arranged simply to revolve on its axis. When we
wish to produce corrugated sheets without a bend in the sheets in addition to
the corrugations, we use two or more pairs of fluted or corrugated rollers, the
axes of each pair are placed one directly over the other, and the two or more
pairs are in the same horizontal plane; but when we wish to produce.a
bending of the plates in addition to the corrugations, then we place the axis
of the lower roller somewhat in advance of the axis of the upper roller, so
that the sheet in passing between the pair of rollers will be turned or curved
upwards in addition to the corrugations. On the other hand, if the axis of
the lower roller be somewhat behind the axis of the upper roller of a pair
the sheet in passing between a pair of rollers will in addition to being corru-
gated or fluted get a curve downwards. Sometimes we place one or more of
the pairs of rollers a little above or a little below the horizontal line, and then
we prefer to assist the rollers in the deflection of the sheet by employing a
suitable guide piece, or it may be a guide roller grooved. The amount of
Curve which can be given with safety must depend upon the quality of the

page_text: iron to be operated upon, and of which a workman will readily judge. When
we wish to give a fluted, undulated, or corrugated surface to sheets already
connected together into a long or continuous sheet we sometimes use only one
pair of undulated, fluted, or corrugated rollers. In this case we raise or
depress the upper roller of such pair by means of screws to such a distance
from the under roller, that the sheet in passing widthways between such
upper and under roller shall get impressed, corrugated, or fluted without
being torn or broken. If the flute, undulation, or corrugation thus given in
the first passage of such continuous sheet between the rollers is not suffi-
ciently deep we screw down the upper roller somewhat, and again pass such
slightly impressed continuous sheet between the pair of fluted, undulated, or
corrugated rollers, and thereby deepen the flute or impression previously made
without tearing or breaking the sheet. If still the corrugation or impression
be not sufficiently formed we again screw down the upper roller, and pass the
connected or continuous sheet again between the pair, and so on, until the
desired flute, undulation, or corrugation is obtained.
We claim, firstly, the production of flutes or corrugations on sheets of iron
or other material by passing them widthways between, under, or against two
or more pairs of fluted rollers, as above described.
Secondly, the use of a roller and bed for the same purpose, as described.
Thirdly, the causing sheets of iron or other metal connected together into
a long or continuous sheet to pass widthways under or against a fluted, undu-
lated, or corrugated roller when working in connection with a bed, or to pass
widthways between or against one or more pairs of fluted, undulated, or
corrugated rollers, in order to be suitably impressed or corrugated, as
described, without tearing it.
In witness whereof, we, the said Edmund Morewood and Andrew
Whytock, have hereunto set our hands and seals, this Twenty-third
day of September, in the year of our Lord One thousand eight hundred
