IMPROVEMENTS IN MACHINES FOR CLEANING KNIVES
Year: 1857

page_text: LETTERS PATENT to Uriah Scott, of Camden Town, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN MACHINES
FOR CLEANING KNIVES."
Sealed the 2nd March 1858, and dated the 5th September 1857.
PROVISIONAL SPECIFICATION left by the said Uriah Scott, at the Office
of the Commissioners of Patents with his Petition, on the 5th September
1857.
I, URIAH SCOTT, of Camden Town, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR CLEANING KNIVES," to be as follows :--
The improvements consist in coiling a piece of buff leather or other similar
material, and placing it in a cup when coiled, leaving a portion to project
beyond the edges of the cups, to form the cleaning portion of the buff
leather. I then fix two such cups on two spindles by their backs with the
two buff leather faces opposite to each other; I then give a rotatory motion
to them by cog wheels or similar means. Or instead of coiling the leather or
other similar material, I have the cups made with grooves to hold the leather
or other similar material in its place. The cups can be made of wood or
metal or other materials.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Uriah Scott, in the Great Seal Patent Office, on the 5th
March 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME I, URIAH
SCOTT, of Camden Town, in the County of Middlesex, Engineer, send
greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of September, in the year of our Lord One
thousand eight hundred and fifty-seven, in the Twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Uriah Scott, Her special licence, that I, the said Uriah Scott, my executors,
administrators, and assigns, or such others as I, the said Uriah Scott, 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 "IMPROVEMENTS IN MACHINES FOR CLEANING
KNIVES," upon the condition (amongst others) that I, the said Uriah Scott,
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 Uriah Scott, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
that is to say:
First, the improvement consists in coiling a piece of buff leather, felt, or
other similar material, and placing it in a cup when coiled, leaving a portion
to project beyond the edges of the cups, to form the cleaning portion of the
buff leathers. I then place two such cups having sockets fixed or cast on
their backs to two spindles fixed opposite to each other, and the spindles not
to project through the cups; I then place two springs one at the back of each
cup, and a cog wheel on each spindle, having a spring between the cup and
the cog wheel, to press the faces of the buff leathers together; I then give a
rotary motion to the machine by having two other cog wheels to work with
the two fixed at the back of the cups, by having a handle fixed at the end of
the shaft having the two cog wheels upon it.
Secondly, instead of coiling the leather, felt, or other similar material, I
have the cups made with grooves to hold, the leather, felt, or other similar
material in its place; I then fix a bevelled wheel at the back of each of the
cups with the slots in them containing the buff leathers or other material with
a spring placed between the cup and the bevelled wheel to press the faces of
the cleaning surfaces together, I then fix them on spindles as in the other

page_text: machine; I then place a bevelled wheel across to connect the two wheels
together at the back of the cups; I then give a rotary motion to the
machine by fixing a shaft and handle to the cross bevelled wheel, which will
make the cups revolve in opposite direction to each other. The cups can be
made of wood or metal or other material, and the outside case of wood and
metal combined. Now in order fully to describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed, I have
hereto annexed illustrative Drawings, which are hereinafter referred to by.
words, figures, and letters following:-
