I, JOHN HUGGETT of 45 Terminus Road, Eastbourne, in the County of Sussex,
Gentleman do hereby declare the nature of this invention to be as follows :-
-
The object of my invention is to produce a simple and cheap yet efficient machine
for cleaning knives.
According to my invention I arrange vertically the edges of a number of pieces
of leather or equivalent material held edge to edge and between two opposite jaws.
These jaws are carried in a frame, the sides of which are not parallel but converge
from the centre towards each end, and the jaws are formed with rectangular blocks
which enter between the converging frames and thus allow the blocks and conse-
quently the jaws a slight lateral or sideway movement at the ends in which the
leather pieces are held. One or both of the jaws is or are free to slide in the frame
and are provided with spiral or helical springs taking into the blocks and abutting
against screws held in distance pieces which serve to hold together the converging
ends of the side frames in which the blocks slide. By screwing the screws in or
out, the pressure between the edges of the opposite pieces of leather which are held
in the jaws may be varied. When only one of the jaws is supplied with a spring,
the other and opposite jaw may be fixed and held in position by the before mentioned
screw. The blocks are prevented from leaving the converging slide or frame by cross
pieces passing transversely on the underside thereof. The pieces of leather in the
jaws are held a short distance from one another and are caused to correspond edge to
edge with the pieces of leather held in the other jaw and I prefer to distance the said
pieces of leather by means of blocks of india rubber but other equivalent means may
be employed.
To or on the top of one of the jaws I fit a box having a perforated bottom which
is intended to carry a supply of, for example, emery powder, and the said perforated
bottom is arranged to correspond with the meeting edges of the leather pieces under-
neath which point the frame bars are joined together by a distance piece in which a
hole is formed; the emery in the upper box has thus a passage through or between

page_text: the pieces of leather, as well as through the aperture in the distance piece, and falls
below into a drawer or other receptacle which prevents any waste.
The action is as follows: The knife to be cleaned is passed between the edges of the
leather pieces, the interstices of which become filled with the polishing powder falling
through from the box above. As the blade of the knife is drawn to and fro between
the leather, a slightly corresponding to and fro lateral motion is communicated to the
blocks and jaw carrying the latter and rubber pieces, the polishing powder falling
through to the tray below, and is replaced when required, in the box above, to be used
over and over again.
The apparatus or appliance may be screwed for convenience to any suitable table
or bench.

A New or Improved Machine or Appliance for Cleaning Knives.
I, JOHN HUGGETT, of 45 Terminus Road, Eastbourne, in the County of Sussex,
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 :-
The object of my invention is to produce a simple and cheap, yet efficient machine
for cleaning knives, and the invention will be best, understood by describing same with
reference to the accompanying drawings.
Figure 1 is a longitudinal vertical section of a machine or appliance constructed
according to my invention, for cleaning knives, Figure 2 is a horizontal section
through the line X Y of Figure 1, Figure 3 is a plan of the apparatus with the box
removed, and Figure 4 is a perspective view of the machine. Similar letters of
reference refer to like parts in all the figures.
According to my invention I arrange vertically the edges of a number of pieces
of leather A or equivalent material, held edge to edge, and between two opposite
jaws B B. These jaws B are carried in a frame C, the sides of which are not parallel
but converge from the centre towards each end, and the jaws are formed with
rectangular blocks D, which enter between the converging frames C and thus
allow the blocks D, and consequently the jaws B, a slight lateral or sideway movement
at the ends in which the leather pieces A are held. One or both of the jaws B is or
are free to slide in the frame and are provided with spiral or helical springs E
taking into or acting on the blocks D and abutting against screws F held in distance
pieces C joining the two ends of the frame C, which serve to hold together the
converging ends of the side frames C in which the blocks D slide. By screwing the
screws F in or out the pressure between the edges of the opposite pieces of leather A
which are held in the jaws B may be varied. When, and as shewn in the drawings,
only one of the jaws B is supplied with a spring, the other and opposite jaw may be
fixed and held in position by the before mentioned screw. The blocks D are prevented
from leaving the converging slide or frame C by cross pieces D' passing transversely
on the underside 'thereof. The pieces of leather A in the jaws B are held a short
distance from one another and are caused to correspond edge to edge with the
pieces of leather A held in the other jaw and I prefer to distance the said pieces of
leather by means of blocks A¹ of india rubber, but other equivalent means may be
employed.
To or on the top of one of the jaws B and blocks D) I fit a box H having a per-
forated bottom J which is intended to carry a supply of, for example, emery powder,
and the said perforated bottom is arranged to correspond with the meeting edges of
the leather pieces A underneath which point the frame bars are joined together by a
distance piece ( in which a hole is formed; the emery in the upper box H has thus
a passage through or between the pieces of leather A as well as through the
aperture in the distance piece (and falls below into a drawer G or other
receptacle which prevents any waste.

page_text: The action is as follows: the knife to be cleaned is passed between the edges of the
leather pieces A the interstices of which become filled with the polishing powder
falling through from the box H above. As the blade of the knife is drawn to and
fro between the leather a slightly corresponding to and fro lateral motion is com-
municated to the blocks D and jaws B carrying the leather A and rubber pieces A¹
the polishing powder falling through to the tray & below, and is replaced when required,
in the box H above, to be used over and over again.
The apparatus or appliance may be screwed for convenience to any suitable table or
bench.
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 :-
First. In machines or appliances for cleaning knives, the jaws B with blocks D
working in non parallel frames C, the said jaws and blocks being provided with leather
rubbing surface edges A between which the knives to be cleaned are pushed to and
fro and thereby imparting a corresponding motion to the leather rubbing surfaces and
parts connected therewith, whereby the polishing material is caused to travel through
and between the leather surface edges and to act with great effect on the knife blade,
all substantially as and for the purposes hereinbefore described and illustrated in the
accompanying drawings.
Second. The general construction and combined arrangement of machines or
appliances for cleaning knives, substantially as herein before described with reference
to the accompanying drawings together with any mere modification or modifications
thereof.

HUGGETT.
