IMPROVEMENTS IN MACHINES FOR CLEANING KNIVES
Year: 1884

page_text: I, ROUGHSEDGE WALLWORK, Ironfounder Union Bridge Iron Works, Charter
Street Manchester in the County of Lancaster of the Firm of Henry "Wallwork
and Company Ironfounders of the above address do hereby declare the nature of
my invention for IMPROVEMENTS IN MACHINES FOR CLEANING KNIVES to be as
follows:-
. The Machine consists of a Base Casting which is secured to the Table by means
of Screws, or, Cramp, and into this Casting fitting in a recess formed in the same
is a Piece of Cork of suitable shape into which Groves may be cut for the purpose
of allowing space for the Knife Cleaning Powder, In connection with the Base
Casting, and held in connection with the Base, by means of thumb Screws and
Springs, is another Casting This Casting which at the same time forms a Recepticle
for the Cleaning Powder lias also a Recess formed in it upon the Under Side into
which another Piece of Cork corresponding in shape to the Piece in the Base, this
Piece is perforated with a number of holes, and there are corresponding holes in
the Casting so that the Cleaning Powder, has a Clear Passage from the recepticle in
the top Casting, first through the Holes in the Casting, and then through corre-
sponding holes formed in the Cork-and in this manner the Cleaning Powder is
guided upon the face of the Piece, or, Pad of Cork that is in the Recess in the
Bottom Casting. The Knife to be Cleaned is easily forced backwards and forwards
between the two Pieces, or, Pads of Cork and the Pressure upon the knife is
regulated by means of the Springs and Screws arranged for this purpose.
Dated this 12th day of December 1884.

Street Manchester in the County of Lancaster, of the Firm of Henry Wallwork &
Company of the same address do hereby declare the nature of my invention for
IMPROVEMENT IN MACHINES FOR CLEANING KNIVES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
Refering to the sheet of Drawings-Fig. 1. shows a front elevation in Partial
Section Fig. 2 shows an end Elevation also Part in Section-and Figures 3. 4. 5.
6. 7. 8 and 9 show various parts, and, views of parts of Figs. 1 and 2. My
improvement consists in the Construction, and, arrangement of a Knife Cleaner
as shown in Figs. 1 and 2. and principally in the use of Cork in its natural state
cut into the desired shapes to form Pads or, Surfaces upon which to place the
'neccessary knife cleaning Powder, or, compositions in general use. Refering to
Fig. 1 and 2-A. A 1. show the Cork Pads refered to above, and Fig. 3. 4. 5. 6
and 7 show various views of the same when out of position-B is a Base casting
arranged to be secured to the bench or table by Screws. at B1-C is top part of
Machine This part is also arranged as a receiver for the various, and, neccessary
Knife Cleaning Powders which naturally falls through the holes C1 in the Casting
which correspond with holes in the top Cork Pads at C3 which let the Powder
down upon the Bottom Pad A'1. the action of cleaning the knives which is done
by forcing the Blade between the two Pads A and A1 in the direction of
this opens the Pads a little and allows the Powder to get between, Any superfluous
Powder that may fall goes into two small lose drawers, or, Boxes E. E 1. so as to
be replaced into the hopper, or, receiver C. The neccessary pressure upon the knives
when between the Pads is put on by the springs F and regulated by the Screws F 1
which screw into Bar F2 to regulate the Pressure-Fig. 8 and 9 show two views
of a small cork Pad this fits into a recess in the Casting made for this purpose as
shown at G. Figs. 1 and 2.
D
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.
Firstly. The general construction of a Knife Cleaner as shown in. Drawings
Figs. 1 and 2 with Pads of Cork as shown.
Secondly. The Use of Cork in its natural state cut into any desired shape for the
purpose of Cleaning knives.
