PROVISIONAL SPECIFICATION.
Improvements in Knife Cleaning Apparatus.
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 knife cleaning apparatus and its
object is to provide a cheap and efficient apparatus adapted to simultaneously
clean the back as well as both sides of the knife.
For this purpose I employ two rubbers mounted with their acting faces placed
face to face in a vertical position in a wooden, metal or other suitable casing.
The said rubbers are more or less pressed towards each other by a spring, a
screw or equivalent device adapted to impart the required pressure. The front
of the casing is provided with a slot or opening to admit the knife to be cleaned,
which is effected by repeatedly pushing the knife blade through this opening and
between the rubbers and partly withdrawing it until the required polish is imparted
to it. The said rubbers are preferably faced with a number of rounded or other
suitably shaped projections or cross ribs formed of india rubber and preferably
inclined away from the front so as to readily allow the knife to be passed between
the rubbers without damaging them. Other elastic or pliable material formed
in a similar way may be employed instead of india rubber. A space is provided
above the rubbers to contain the polishing powder which falls down between the
rubbers and the ribs on their face as required. A suitable lid is fitted in the
top to allow the polishing powder to be inserted. The knives are intended to
be cleaned with their backs downward and the bottom of the casing forms a
rubber for the back, or the bottom may be faced with any suitable material.
A small receptacle may be provided in front below the said opening to collect
any of the powder that may work out with the motion of the knife but I find
there is very little waste as the inclined rib formation of the rubber has a tendency
to prevent the powder passing out of the opening. A sheath or continuation of
the case may be provided at the back to receive the point of a knife longer
than the rubbers.
To enable the apparatus to be firmly held whilst in use without the necessity
of fixing it I form a handle on the top, and a projection on the bottom adapted
to engage the front of the table or other support.
Dated this 23rd day of February 1894.

I, THOMAS FERNELEY WILEY, of Rawdon, near Leeds, in the County of
York, 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 rubbers mounted in a casing, and its object is to render this class of appliance
or machine more effective.
For this purpose I form the faces of the rubbers of a number of rounded
projections or cross ribs formed of india rubber and inclined away from the front
so as to readily allow the knife to pass between the rubbers without damaging
them. Other elastic or pliable material formed in a similar way may be employed
instead of india rubber.
In order to clearly and fully describe my invention I have appended a sheet of
drawings hereto in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a longitudinal sectional elevation of my improved appliance
on the broken line a, b Figure 5.
Figure 2, represents a front view of the same.
Figure 3, represents a plan view; and Figure 4, represents a cross section of the
same on the broken line y, z shown on the former figure.
Figure 5, represents a plan view of the appliance without the lid.
The casing A is formed of wood or other suitable material and is provided with
a lid or cover A² secured in position by the tongue A³ at the front fitting a groove.
in the casing, and by the turn button A* screwed to the top of the casing at the
other end. The lid rests upon the adjustable piece B which latter may be adjusted
by the screw C fitted in the side of the casing. The two rubbers D and D² are
placed face to face and each have a number of soft or pliable projections d inclined
away from the opening E in the casing through which the knife is admitted. The
rubber D is cemented or otherwise secured to the face of the piece B and the
rubber D is similarly secured to the opposite side of the casing.
struction of rubber forms a pliable and elastic face which presses fairly uniformly
upon the knife when it is presented between the rubbers (as shown by the broken
lines H Figure 1) notwithstanding the varying thickness of the blade, and knives
of different size and thickness within ordinary limits may be inserted and cleaned
without it being necessary to adjust the screw C. A glass or other hard disc or
button O is preferably let into the bottom of the casing to prevent the back of the
knife wearing into it.
This con-
A small receptacle may be provided in front below the opening E to collect any
of the cleaning powder with which the rubbers are fed from above from working
out with the motion of the knife but I find there is very little waste as the inclined
rib formation of the rubber has a tendency to prevent the powder passing out of
this opening.
To enable the apparatus to be firmly held whilst in use without the necessity of
fixing it I form a handle J at the top of the lid and also a projection K on the
bottom of the casing adapted to engage the front of the table or other support.
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 :
A knife cleaning appliance of the type herein specified in which the rubbing

page_text: faces are formed of rounded projections or cross ribs inclined away from the
front of the appliance, substantially as herein shown and described and illustrated
in the accompanying drawings.
