PROVISIONAL SPECIFICATION.
An Improved Machine for Cleaning Knives, Forks, and Spoons.
I JOHN ISHERWOOD of 23 Lodge Road Hindsford Atherton in the County
of Lancaster Maker-up do hereby declare the nature of this invention to be as
follows:-
This invention consists principally of two rollers mounted one above the other in
parallel positions. These rollers are covered with bristles so as to form brushes, or
with strips of felt, or buff leather fast at one edge only or with other material
suitable for brushing or polishing the surfaces of the articles.
The form of the rollers is made to correspond with that of the articles, one
roller being the counterpart of the other; that is to say, opposite portions of each
roller will be made flat for cleaning the knives, forks, and the handles of spoons,
and other opposite portions are made curved so as to correspond with the form of
the bowls of spoons of two, three, or more sizes, as may be required; one of the
rollers being curved in convex forms to fit inside of the bowls, and the other made
concave to correspond with the outsides of the same.
The rollers are enclosed in a box or casing and above them is mounted a sieve
with a perforated bottom to receive the whiting or other polishing powder employed,
and a reciprocating motion is given to this sieve by a cam or crank actuated by one
of the rollers.
One of the rollers is driven either by hand by means of a winch handle or by a
treadle and crank worked by the foot, and this roller drives the other one by bevil
wheels or other suitable gearing.
The knives forks or spoons are introduced through openings in the side of the
box or casing at right angles to the axes of the rollers, so that they pass between
the two rollers and are brushed or rubbed on both sides at the same time, the
openings being provided with bristles or flaps of cloth felt or leather which will
allow the articles to be introduced and removed but will at the same time prevent
the whiting or powder from escaping.

COMPLETE SPECIFICATION.
An Improved Machine for Cleaning Knives, Forks, and Spoons.
I JOHN ISHERWOOD of 23 Lodge Road Hindsford Atherton in the County
of Lancaster Maker-up 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 the construction of a simple machine or apparatus for
cleaning and polishing knives forks and spoons.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is an elevation of my improved machine with the casing
removed and Fig. 2 is a vertical section of the same through about the line A-B
in Fig. 1.
.
The machine consists principally of a frame a in which two rollers c and d are

page_text: mounted one above the other in parallel positions. These rollers are covered with
bristles so as to form brushes (as shown at c¹ d¹) or with strips of felt or buff
leather fast at one end only (as shown at el d¹¹), or with other material suitable for
brushing or polishing the surfaces of the articles.
C
The form of the rollers c and d is made to correspond with that of the articles,
one roller being the counterpart of the other; that is to say, opposite portions of
each roller will be made flat for cleaning knives, forks, and the handles of spoons,
and other opposite portions are made curved so as to correspond with the form of
the bowls of spoons of two, three, or more sizes as may be required; one of the
rollers being curved in convex forms to fit inside of the bowls, and the other made
concave to correspond with the outsides of the same, as clearly shown at Fig. 1.
The bristles, if such are employed, may either be set direct into holes in the roller
or they may be set in india rubber or other suitable material and applied to the
surface of the rollers.
The rollers c and d are enclosed in a box or casing e and above them is mounted
a sieve with a perforated bottom to receive the whiting or other polishing powder
employed, and a reciprocating motion is given to this sieve by a cam g or a crank
actuated by one of the rollers.
One of the rollers is driven either by hand by means of a winch handle and
spur gearing or by a treadle and crank worked by the foot, or by other power,
and this roller drives the other by the bevil wheels or by other suitable
gearing.
l
The knives, forks, or spoons are introduced through openings in the front of the
box or casing e at right angles to the axes of the rollers c and d so that they pass
between the two rollers and are brushed or rubbed on both sides at the same time,
the rollers being preferably provided with thin flanges (shown only on Fig. 1) to
keep the articles from being displaced laterally; and the openings in the casing e
may be provided with bristles, or with flaps of cloth felt or leather which will
allow the articles to be introduced and removed, but will at the same time prevent
the whiting or other powder from escaping.
The coiled spring m on the bevil wheel shaft is to keep the bevil wheels in gear
and at the same time allow of the upper roller c being set down from time to time
by the adjusting screws n as the rollers become worn.
The casing e is provided with a drawer o beneath the rollers to receive the
whiting or other powder which may be withdrawn when necessary and emptied back
into the sieve f. This machine will be found to be less injurious to the knives &c.
than the ordinary machines are.
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 :-
The improved machine for cleaning knives, forks, and spoons, consisting
principally of two revolving rollers made with concave convex and flat surfaces
so as to be counterparts of each other, and provided with bristles, strips of felt.
buff-leather fast at one end only, or other suitable material for brushing or
polishing the flat concave and convex surfaces of the articles substantially as
herein before described and illustrated by the drawings annexed.
Dated this 2nd day of February 1892.
