Complete Specification Left, 19th Mar., 1897-Accepted, 12th June, 1897
We, JOHN HALL, of 1, Alexander Crescent, Leeds, in the County of York,
Engineer and GEORGE JENNINGS, of Mill Lane, Bradford, in said county,
Machine Broker, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in machines or appliances for cleaning
table knives, and its object is to provide a cheap and efficient machine comparatively
easy to use.
a
For this purpose we employ a bed piece which may be secured to a table or
the like in any convenient manner. This bed piece is made with a convex face
that is to say: curved from end to end. A rocking piece is mounted upon this
face and its under face is made of similar curved or convex form. Strips of
emery cloth or its equivalent are stretched over the curved faces and the ends
of the emery cloth may be secured in slots or openings at the ends of the curved
faces by means of suitable wedges. A layer of felt or the like is preferably placed
between the back of the emery cloth and the curved faces. To hold the rocking
piece in position a bearing pin or lug is formed on one or both sides of it and this
lug or lugs engage a bearing or bearings formed on the bed piece. The sides of the
curved face on the bed may be raised above this curved face so that the rocking piece
more or less lies between them.
To clean a knife the blade is passed between the curved faces and is moved
in and out between the emery faces until the desired polish is given to it.
And to regulate the pressure between the emery faces and also to bring any
part of the two faces to bear upon the blade a horizontal lever is provided
pivoted on a vertical stud on one side of the bed piece. This lever may be pressed
upon and be moved horizontally over a concavely curved rib on the upper side of
the rocking piece for the purpose of bringing any particular part of the curved
faces together.

Improvements in Knife Cleaners.
We, JOHN HALL, of 1, Alexander Crescent, Leeds, in the County of York,
Engineer, and GEORGE JENNINGS, of Mill Lane, Bradford, in said county,
Machine Broker, 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 :-

table knives, and its object is to provide a cheap and efficient machine comparatively
For this purpose we employ a bed pièce which may be secured to a table or the
like in any convenient manner. This bed piece is made with a convex face that is
to say curved from end to end. A rocking piece is mounted upon this face and
its under end is made of similar curved or convex form. Strips of emery cloth or its
equivalent are stretched over the curved faces and the ends of the emery cloth are
secured in slots or openings at the ends of the curved faces by means of suitable
wedges. A layer of felt or the like is preferably placed between the back of the emery
cloth and the curved faces. To hold the rocking piece in position a bearing pin
or lug is formed on one or both sides of it and this lug or lugs engage a bearing
or bearings formed on the bed piece. The sides of the curved face on the bed may
be raised above this curved face so that the rocking piece more or less lies
between them.
To clean a knife the blade is passed between the curved faces and is moved
in and out between the emery faces until the desired polish is given to it.
And to regulate the pressure between the emery faces and also to bring any
part of the two faces to bear upon the blade a horizontal lever is provided pivoted
on a vertical stud on one side of the bed piece. This lever may be pressed
upon and be moved horizontally over a concavely curved rib on the upper side
of the rocking piece for the purpose of bringing any particular part of the curved
faces together.
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.
Figure 1, represents a side elevation of our improved machine.
Figure 2, represents a plan view and Figure 3, an end view of same.
Figure 4, is a side view showing the bed piece in section and the rocking
piéce in position for cleaning the shoulder of the knife. Figure 5, represents
a similar view but with the rocking piece in position for cleaning the point of the
knife.
The bed A is made with lugs A 2 by which it may be secured to a table or the
like. The upper face A 3 of the bed is curved as shown and it is also preferably
slightly inclined laterally as well as the underside of the rocking piece B to allow
of the difference between the thickness of the edge and the back of the knife.
In Figure 3, K represents a cross section of the knife in position. The bed A is
made with sides A 4 in which slots A 5, A 5 are cast to receive the trunnions
or projections B2, B2 on B. A rib B3 is formed on B the upper edge B4 of
which is curved concavely in such a manner that when the lever C is moved
horizontally over the curved edge of the rocking piece B is moved from the position
shown in Figure 4 to that shown in Figure 5 so that by adjusting the position of
the lever C any portion of the curved under face B5 of B may be brought in
contact with the face A 3.
The lever C is pivoted upon the adjustable stud or bolt D fixed in the bracket A 6
cast on the side of the bed A.
The curved faces A 3 and B5 are covered with felt For similar material cemented
in position and strips of emery cloth E are stretched over the felt and the ends E2
confined in the slot or opening G by the wedge H.
The sides A 4 are preferably lined with leather A7 or other suitable material
cemented in position.
"
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. The combination with the curved bed A of the rocking piece B; substantially
as herein shown and described and for the purpose specified.
