Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COM, we, JAMES
ALLISON, of Monkwearmouth, in the County of Durham, Iron Master, and
ROGER LUMSDEN, of the same place, Chain and Anchor Manufacturer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Thirtieth day of May, in the third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said James Allison and Roger Lumsden, Her especial licence, full
power, sole privilege and authority, that we, the said James Allison, and
Roger Lumsden, our exors, adñiors, and assigns, or such others as we, the
said James Allison and Roger Lumsden, our exors, adñiors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, our Invention of "IMPROVEMENTS IN THE MANUFACTURE
OP IRON KNEES FOR SHIPS AND VESSELS;" in which said Letters Patent is
contained a proviso, that we, the said James Allison and Roger Lumsden,
or one of us, shall cause a particular description of the nature of our said
Invention, and in what manner the same is to be performed, to be inrolled in
Her said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
largo appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, we, the said
James Allison and Roger Lumsden, do hereby declare the nature of our said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and to the figures and letters
marked thereon (that is to say):-
According to the ordinary means now resorted to for making iron knees
for ships and vessels, it is usual to forge each half or arm of a knee by
hammering, which requires considerable skill and much time in performing,
and the two arms or halves of a knee are then welded together.
Figure 1 shews a half of a knee, and Figure 2 shews a complete knee.
Now, according to our Invention we form the two parts of a knee by means
of rollers in place of forging by hand, by which the skill heretofore required
in forging will be dispensed with, and time saved in the manufacture of knees
for ships and vessels.
Figure 3 shews a pair of rollers suitable for making knees according to
our Invention, but the cog wheels are not shewn by which the rollers are
driven together; such wheels will readily be applied by a workman acquainted
with the rolling of iron. There are two rollers, as if it was intended to
make flat bars of iron, except that in the upper roller shewn by an end view,
As the rolls turn round the heated
Figure 4, there are parts cut away.
iron is put into the roller where the notch is; the roller tapers the iron into
the shape of a long wedge of an equal breadth; as it turns round it is passed
through the rollers a sufficient number of times until finished, when it is in
the shape of a long wedge as shewn at Figure 1, and precisely what is formed
by the forge hammer, and two of these arms have to be welded together to
make a knee in like manner to that pursued on the old plan.
Having thus described the nature of our Invention, and the manner o
performing the same, we would have it understood that what we claim is, th
mode of manufacturing knees for ships and vessels by means of rollers a
described.
In witness whereof, we, the said James Allison and Roger Lumsder
have hereunto set our hand and seals, this Twenty-third day
November, in the year of our Lord One thousand eight hundred an
