Year: 1857

page_text: LETTERS PATENT to John Woodley and Henry Herbert Swinford, both
of Limehouse, in the County of Middlesex, Coopers, for the .Invention
of "IMPROVEMENTS IN SAWING MACHINES."
Scaled the 12th June 1857, and dated the 5th March 1857.
PROVISIONAL SPECIFICATION left by the said John Woodley and Henry,
Herbert Swinford at the Office of the Commissioners of Patents, with
their Petition, on the 5th March 1857.
We, JOHN WOODLEY and HENRY HERBERT SWINFORD, both of Limehouse;
in the County of Middlesex,. Coopers, do hereby declare the. nature of. the
said Invention for "IMPROVEMENTS IN SAWING MACHINES," to be as follows:-
Our said improvements consist in certain mechanical arrangements of
wood-sawing machines, to produce suitable curves when sawing wood for staves
and other like purposes.
The band or other saws work through the bed plate or table of the sawing:
machine between two guide rollers, one of which is a plain binding roller, the
other, acting as a templet, is a cam or excentric, furnished with points, or like.
means for carrying the wood forward, and it is adjusted by a regulating screw.
Two or more roughened guide rollers are placed in any convenient position
for guiding the wood while being sawn.... Templets of the common form may,
be substituted, made of leather, gutta percha, vulcanized india-rubber, or other
flexible materials.

by the said John Woodley and Henry Herbert Swinford in the Great
Seal Patent Office on the 31st August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WOODLEY and HENRY HERBERT SWINFORD, both of Limehouse, in the County
of Middlesex, Coopers, 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 us, the
said John Woodley and Henry Herbert Swinford, Her special licence that
we, the said John Woodley and Henry Herbert Swinford, our executors,
administrators, and assigns, or such others as we; the said John Woodley
and Henry Herbert Swinford, our 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, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN SAWING MACHINES," upon the condition (amongst others) that
we, the said John Woodley and Henry Herbert Swinford, our executors or
administrators, by an instrument in writing under our, or their, or one of
their hands and seals, should particulary 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 inmediately after the date of the said Letters
Patent.
NOW KNOW: YE, that we; the said. John Woodley and Henry Herbert
Swinford, 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 statement:
Our said improvements consist in certain mechanical arrangements of wood-
sawing machines, to produce suitable curves when sawing wood for staves and
other like purposes. And for the better understanding of our said Invention,
we will now proceed to detail the particulars thereof, reference being had to
the Drawings hereunto annexed, in which the same letters refer to like parts
throughout.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of the saw-bench, frame, and template; Figure 2 is
a plan of Figure 1; and Figure 3 is a plan of a stave and flexible template.
A is a revolving template; B, B', a stave; C, a binding roller; D, friction
rollers; E, the bench or table; a, a regulating screw; F, a flexible template;
G, a roller or guide, as applied to the form shown in Figure 3, otherwise a
cam is used like A; and x, y, is the direction of the saw cut.
Having thus described our said Invention we would here remark, that the
band or other saws used in our machines work through the bed plate or table
of the sawing machine between two guide rollers, one of which is a plain
binding roller, the other, acting as a template, is a cam or eccentric, furnished
with points or like means for carrying the wood forward, and it is adjusted
by a regulating screw. Two or more roughened guide rollers D are placed
in any convenient position for guiding the wood while being sawn. Templates
of the common form may be substituted, made of leather, gutta percha, vul-
canized india-rubber, or other flexible materials. We do not restrict ourselves
to dimensions or materials, or to the precise kind of saws to be used, and we do
declare that what we claim as our Invention is, namely, the novel mechanical
arrangement of wood-sawing machines, as described.
In witness whereof, I, the said John Woodley, on behalf of myself and
the said Henry Herbert Swinford, have hereunto set my hand and
seal, this Seventeenth day of August, in the year of our Lord 1857.
JOHN WOODLEY (L.S.)
