AN IMPROVED SAW- SETTING APPARATUS
Year: 1857

page_text: LETTERS PATENT to George Marshall, of Morpeth, in the County of
Northumberland, Joiner, for the Invention of "AN IMPROVED SAW-
SETTING APPARATUS."
Sealed the 8th September 1857, and dated the 16th March. 1857.
PROVISIONAL SPECIFICATION left by the said George Marshall at the
Office of the Commissioners of Patents, with his Petition, on the
16th March 1857.
I, GEORGE MARSHALL, of Morpeth, in the County of Northumberland,
Joiner, do hereby declare the nature of the said Invention for "AN IMPROVED
SAW-SETTING APPARATUS," to be as follows:-
My improved saw-setting apparatus is constructed with a novel arrangement
of fence and lever. The fence has two or more set screws to move it back-
wards and forwards to suit the setting of saws, and has also a rest for the saw
plate. The lever of my said apparatus has a working joint, and when the
punch is struck to press the saw plate firm on the rest, the lower portion of
the lever moving up and down can be fastened as desired by means of screws,
and a spring is so arranged as to 'force the lever backwards and the punch
upwards. The fence may be variously worked, and the apparatus may be
modified to suit different kinds of saws.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
MARSHALL, of Morpeth, in the County of Northumberland, Joiner, send a
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by IIer Letters
Patent, bearing date the Sixteenth 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 Marshall, Her special licence that I, the said George Marshall, my
executors, administrators, and assigns, or such others as I, the said George
Marshall, 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, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED SAW-SETTING APPA-
RATUS," upon the condition (amongst others) that I, the said George Marshall,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 Marshall, 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:-
My said Invention relates to an apparatus which affords a ready means for
setting accurately the teeth of saws by the aid of suitable mechanical arrange-
ments; and for the better understanding of the same, I will now proceed to
detail the particulars thereof, reference being had to the Drawings hereunto
annexed, in which the same letters refer to corresponding parts throughout.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view, full size, of one mode of constructing my improved
apparatus; and Figure 2 is a side view of the same.
A is the fence; B, B, are binding screws, to secure the fence after being

page_text: moved as much backwards or forwards as required; C, the rest; D, a spring,
made to act on the punch E so as to raise it up after being struck.
It will thus be observed that my improved saw-setting apparatus is con-
structed with a novel arrangement of fence and spring, or a lever to answer
the same purpose. The fence bas two or more set screws to move it back-
wards and forwards, or to secure it when adjusted to suit the setting of saws;
and has also a rest for the saw plate. The spring used in one mode of con-
structing my said apparatus is made so that when the punch is struck it
operates to press the saw plate firm on the rest, and at the same time is so
arranged as to force the punch up after each stroke. The fence may be
variously worked, and the apparatus may be modified to suit frame, large, and
different kinds of saws; I therefore do not limit myself to the precise details
herein set forth so long as the principle of my said Invention is retained in any
modification thereof; and I do declare that what I claim as my Invention is,
namely, the novel mechanical arrangement of apparatus for setting saws, as
described.
In witness whereof, I, the said George Marshall, have hereunto set my
hand and seal, this Eighth day of September, in the year of our Lord
GEORGE MARSHALL. (L.S.)
