IMPROVEMENTS IN KNIFE CLEANERS
Year: 1884

page_text: I GEORGE PICKETT of the firm of Davison, Hearn and Co. of 84 Hatton Garden
in the County of Middlesex Commercial Agent do hereby declare the nature of
the said Invention for IMPROVEMENTS IN KNIFE CLEANERS to be as follows:-
The Invention has for its object improvements in knife cleaners.
For this purpose I employ a base plate preferably of circular form and dished
on its upper side or provided with a rim in order to act as a tray.
.
In the centre of the base plate or tray I cast or otherwise fix a stud and upon
this stud I loosely fit with capability of revolving and slightly rocking thereon a
disc of wood or other desired material furnished on its under side with a metal-
fitting formed with a socket to receive the stud.
On its upper side the disc is provided with a surface of felt or other suitable.
material to hold polishing powder and to act as a rubbing surface.
A similar disc, also provided with a rubbing surface but on its underside, is,
carried by an arın. hinged to a bracket carried by the base plate or tray and this -
disc when in use rests upon the face of the under disc.
i.
The upper disc is provided with a knob or handle or it may be a lever to enable
the required pressure to be applied by the operator.
In lieu of the stud and fitting, any other device which will allow of the under
disc revolving and slightly rocking may be employed, the object of such movements
being to cause the rubbing surface to be worn equally all over and to enable it to
adjust itself to the form of the knife being cleaned.
In some cases it may be found desirable to apply a similar arrangement to the
upper disc to allow of similar adjustments.
The action of the knife cleaner is as follows.
The upper disc is raised or turned back upon its hinge and the requisite
polishing powder is distributed over the rubbing surfaces; a knife is then
introduced and the upper disc is placed in position upon the under one, the knife
being between the two, and pressure is applied by the operator to the knob,
handle or lever with the one hand while with the other he passes the knife rapidly
to and fro several times between the rubbing surfaces when on removal it will be
found to be thoroughly cleaned on both sides.
Any polishing powder which may fall from the rubbing surfaces is caught by
the tray and may be used again.

in the County of Middlesex, Commercial Agent, do hereby declare the nature of
my said Invention for IMPROVEMENTS IN KNIFE CLEANERS and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
The Invention has for its object improvements in knife cleaners.
For this purpose I employ a base plate preferably of circular form and dished on
its upper side or provided with a rim in order to act as a tray.
In the centre of the base plate or tray I cast or otherwise fix a stud and upon.
this stud I loosely fit with capability of revolving and slightly rocking thereon a
disc of wood or other desired material furnished on its under side with a metal'
fitting formed with a socket to receive the stud.
:
On its upper side the disc is provided with a surface of felt or other suitable
material to hold polishing powder and to act as a rubbing surface.
A similar disc, also provided with a rubbing surface but on its underside, is
carried by an arm hinged to a bracket carried by the base plate or tray and this
disc when in use rests upon the face of the under disc.
The upper disc is provided with a knob or handle or it may be a lever to enable
the required pressure to be applied by the operator.
In lieu of the stud and fitting, any other device which will allow of the under
disc revolving and slightly rocking, may be employed, the object of such movements
being to cause the rubbing surface to be worn equally all over and to enable it to
adjust itself to the form of the knife, being cleaned.
In some cases it may be found desirable to apply a similar arrangement to the
upper disc to allow of similar adjustments.
The action of the knife cleaner is as follows: The upper disc is raised or turned
back upon its hinge and the requisite polishing powder is distributed over the
rubbing surfaces; a knife is then introduced and the upper disc is placed in position.
upon the under one, the knife being between the two, and pressure is applied by
the operator to the knob, handle or lever with the one hand, while with the other
he passes the knife blade rapidly to and fro several times between the rubbing
surfaces when on removal it will be found to be thoroughly cleaned on both sides.
Any polishing powder which may fall from the rubbing surfaces is caught by
the tray and may be used again.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation Figure 2 is a plan and Figure 3 is a cross section of a
knife cleaner constructed according to my Invention.
a is the base plate which I preferably make of circular form and dished on its
upper side or provided with a rim a¹ as shown to act as a tray.
In the centre of the base plate or tray I cast or otherwise fix a stud a² preferably
of taper form and upon this stud I loosely fit, with capability of revolving and
slightly rocking thereon a disc b of wood or other desired material furnished on its
underside with a metal fitting b¹ formed with a socket to receive the stud a².
On its upper side the disc b is provided with a surface 62 of felt or other.suitable
material to hold polishing powder and to act as a rubbing surface.

page_text: A similar disc c also provided with a rubbing surface c', but on its underside, is
carried by an arm c³ hinged to a bracket a³ carried by the base plate or tray a and
this disc when in use rests upon the face of the lower disc b.
The upper disc c is provided with a knob or handle or it may be a lever to
enable the required pressure to be applied by the operator.
In lieu of the stud and fitting any other device which will allow of the under
disc b revolving and slightly rocking may be employed, the object of such
movements being to cause the rubbing surface to be worn equally all over and to
enable it to adjust itself to the form of the knife being cleaned.
In some cases it may be founed desirable to apply a similar arrangement to the
upper disc c to allow of similar adjustments.
The action of the knife cleaner is as follows. The upper disc c is raised or
turned back upon its hinge and the requisite polishing powder is distributed over
the rubbing surfaces; a knife is placed in position upon the under one b, the knife
being between the two, and pressure is applied by the operator to the knob handle
or lever with the one hand while with the other he passes the knife blade rapidly
to and fro several times between the rubbing surfaces when on removal it will be
found to be thoroughly cleaned on both sides.
Any polishing powder which may fall from the rubbing surfaces is caught by
the tray a and may be used again.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:
A knife cleaner consisting of tray a lower rubbing disc b mounted loosely on its
support or axis a upper rubbing disc c fixed to arm c² which is hinged to
bracket a³ and provided with a knob or handle ca substantially as herein shown
and described and for the purpose stated.
