PROVISIONAL SPECIFICATION.
An Improved Apparatus for Cleaning Knives.
1, EDWARD JOHN CHARLES SHARP, Engineer, Sharratt Street Old Kent
Road London, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple, cheap and effective apparatus
for cleaning and polishing knives, more readily and conveniently then they can be
cleaned by any ordinary machine.
My improved apparatus consists of a lay-board of a suitable length and width
and shape. I secure a knife-rest across the center of board convenient in width and
thickness of suitable material. I fix a guard board all round to a convenient
hight with springs fixed at both ends of the board. The face of the lay-board
I make groves to any number in size or width or shape or by any other means.
The rubber is a block suitable in size and shape with a raised handle so as to
be conveniently grasped by the hand. The underside of the rubber being covered
with leather or other suitable material to any shape or form.
The method of using my improved apparatus is as follows:-The knife is held
by the handle with its blade resting upon the rest of the board. Any suitable
knife-cleaning powder is then applied upon the board and the knife is rubbed
therewith transversely. The knife is thus cleaned and polished quicker and more
readily and with less labour then any other systems including the backs and
shoulders.

more readily and conveniently then they can be cleaned by any other system.
My improved apparatus consists of a lay base-board A of a suitable length and
width and shape. "I secure a knife rest B across the center of board convenient in
width and thickness of suitable material. I fix a raised rim C all round the board
to a convenient hight with a receiver D at one or both ends, with springs E most
suitable fixed on at each end of the board.
The face of the lay base-board I grove F or sinkings to any number in shape or
form and depth and size. The rubber consists of a block suitable in size G and shape
with an handle so as to be conveniently grasped by the hand. The under side of
the said block H being covered with prepared leather or other suitable material to
any shape or form.
The method of using my improved apparatus is as follows. The knife is held by
the handle with its blade resting longitudinally upon the rest of board B. Any
suitable kind of knife cleaning powder is then applied upon the board A the knife
is rubbed therewith transversly the full length of the rubber. The blade,
shoulders and back is thus cleaned and polished quicker and with less labour then
