PROVISIONAL SPECIFICATION.
Improvements in Appliances or Machines for Cleaning Knives,
I, THOMAS FERNELEY WILEY, of Rawdon, near Leeds, in the County of
York, Gentleman, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in that type of appliance or machine for
cleaning knives in which the knife is reciprocated horizontally by hand between
two vertical rubbers mounted in a box or casing and particularly to the machine
in which the said rubbers are faced with rounded india rubber projections inclined
away from the front. And the object of the invention is to increase the efficiency
and durability of this class of machine.
As there is more wear and tear upon the rubbers at the lower side, or part of
the rubber acting upon the thicker edge of the blade, I arrange the iubbers so
that they may be interchangeable or their position reversed and at the same time
trup blue down. For this purpose the rubbers may be mounted on thin loose
backing strips of wood or other suitable substance and the backing strips may be
ained in position by piss or the like fixed in the side of the box and in the
able piece arranged to engage notches or their equivalent form in the said
1
sto.
to clean the shoulders of the knives the front projections are modified
in form and more or less project and are so arranged that each time the shoulders
of the Life are pushed against them they are sufficiently elastic to allow the
shoulders to pass between them to clean them.
To increase the elasticity of the projections on the rubbers and adapt them to
accommodate themselves to the unequal thickness of a knife without undue friction
I prefer to more or less reduce the thickness of the projections towards the root,
or at the root, so as to make them more pliable and preferably arrange the
projections that one does not overlap the other.
Dated this 1st day of May 1894.

COMPLETE SPECIFICATION.
Improvements in Appliances or Machines for Cleaning Knives.
I, THOMAS FERNELEY WILEY, of Rawdon, near Leeds, in the County of
York, Gentleman, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in that type of appliance or machine for
cleaning knives in which the knife is reciprocated horizontally by hand between
two vertical rubbers mounted in a box or casing and particularly to the machine
for which I have made application for Letters Patent No. 3943 and dated
24th February 1894. And the object of the invention is to increase the efficiency
and durability of this class of machine.
As there is more wear and tear upon the rubbers at the lower side, or part of
the rubbers acting upon the thicker edge of the blade, I arrange the rubbers so
[D027

page_text: that they may be interchangeable or their position reversed and at the same time
turned up side down.
In order to clean the shoulders of the knives the front projections are modified
and are so arranged that each time the shoulders of the knife are pushed against
them they are sufficiently elastic to allow the shoulders to pass between them to
clean then.
To increase the elasticity of the projections on the rubbers and adapt them to
accommodate themselves to the unequal thickness of a knife without undue friction I
prefer to more or less reduce the thickness of the projections towards the root, or
at the root, so as to make them more pliable and I preferably arrange the
projections that one does not overlap the other.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.

on the broken line a, b
Figure 5, represents a plan view of the machine with the lid or cover
removed.
Figure 6, represents an elevation of one of the rubbers shown separately.
Figure 7, is a plan view of the same.
The rubbers D, D are connected or otherwise secured on thin backing strips L
and L of wood or other suitable material and these strips are held in position in
the case by the notches M formed in them engaging the pins N and N' respectively
fixed in the side of the casing A and in the adjustable piece B.
By this arrange-
ment the position of the two strips and rubbers may be reversed and inverted.
The front ends of the rubbers pass into and through the opening E in the end of
the casing provided for the admission of the knife, represented by the broken
lines Z Figure 1.
The projections d on the rubbers are made thinner at or close to the base than
at the middle i so as to be more elastic but still leave ample margin for wear.
The projections d are also made not to overlap each other, and the front faces d
of the end projections d³ are modified. or more rounded in form to enable them to
more closely bear upon, or conform to the shape of, the shoulders of the knife each
time the knife is pushed fully in, they therefore have a greater cleaning action
upon the shoulders.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A knife cleaning appliance of the type herein specified having rubbers
arranged so that their position may be reversed and inverted, substantially as
herein shown and described and for the purpose specified.
2. A knife cleaning appliance of the type specified in which the projections or
cross ribs of the rubbers are reduced in thickness at or close to the base and do
not over-lap each other and in which the frout projection of each of the rubbers
is modified in form so as to more closely bear upon the shoulders of a knife,
substantially as herein shown and described and illustrated in the accompanying
drawings.
Dated this 27th day of February 1895.
