do hereby declare the nature of this invention to be as follows:-
The ordinary knife cleaning machine in rotary form consists of two discs of
wood or metal covered over partly with hair and partly with leather in sections.
The knife is placed between these discs, and the motion is given by a crank
handle. It is desirable that these brushes should be very flexible which has only
been partly obtained by putting strips of leather on edge and backing them with
india-rubber and adjusting the discs by nuts on the spindle at front and back. My
machine consists of two discs lastened to a spindle. Upon both of these discs
are stretched air-proof canvas, leather, india-rubber or other suitable material.
A cavity is left between the dise and material for inflation. Upon this base of
canvas or other material strips of leather or hair are fastened, and flexibility is
given to these brushes by the inflation thus causing them to be expanded as in the
case of a pneumatic tyre. When they are inflated pressure is brought to bear
upon every part of the blade of the knife, or prongs of forks. When the air is let
out the bags collapse, leaving the knife or fork free to be taken out.

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 ordinary knife cleaning machine in rotary form consists of two discs of
wood or metal covered with segments of hair and leather. The section covered
with bair is for the reception of the knives prior to their passing on to the
leathers, the latter forming the cleaning portion of the discs. These discs are
mounted upon a spindle, the motion of which is given by a crank handle. It is
desirable that these leathers be very flexible, which has only been partly
obtained. It is neccesary that the discs be tightly pressed together to put tension
on the blades of the knives, which is caused by nuts traversing upon the threaded
portion of the spindle at front and back.
Now it is obvious that the leathers being permanently closed together, in time
lose their flexibility, so that with the loss of elasticity and the leathers wearing
away quicker than the bair, the latter becomes interlocked, which results in
twisting and breaking the knives, and doing injury to the machine.
According to my invention the afore-said dis-advantages are greatly minimised,

page_text: there being no nuts for the operator to tighten and no particular position of the
handle to denote when the knives are to be put in the holes.
In my machine the knives may be put in at any position of the handle, so that
the most inexperienced person can use it. According to my invention two iron
discs are mounted upon a spindle at a given distance by means of keys or set
screws, between these discs I place what are called brushes which are made of
strips of leather attached to a base of canvas stretched over a hoop of wood or
iron.
Between these iron discs and brushes, inflatable bags are placed, and the
same are attached to the spindle by means of cement or rubber rings, the said
spindle is tubular having two holes near the centre for the inflation of the air bags
and finished off with a conical end which fits a seating of a similar form formed in
the bearing of one of the standards. Attached at the base of the standards and
immediately under the drum or case of the machine a box is fixed which contains
a bellows, the said bellows acting as an auxiliary air reservoir. A pipe leading
from the bellows to the seating formed in the bearing allows the air being passed
from the bellows to the air bags and vice versa. The bellows are operated upon
by means of a lever handle, which when in use forms a hand rest and when
pressed down enables the operator to put a light or heavy friction on the knives.

through which the air passes into the bags D. D the expansion of the said bags
being equal, cause the brushes which are apart to close tightly together and meet
opposite the median line of the knife holes.
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
1st. A rotary knife and fork cleaning machine provided with the means of
temporary separating and closing the brushes and giving flexibility to the same by
means of inflatable bags, substantially in the manner and for the purpose specified.
2nd. The inflating of the air bags by means of an auxiliary air reservoir in the
form of a bellows acted upon by means of a leaver, substantially as shown and
described for the purpose specified.
