COMPLETE SPECIFICATION.
Improvements in Knife Cleaning Machines.
I, FREDERICK WILLIAM FOLLOWS, of Gorton, in the County of Lancaster,
Engineer and Agricultural Implement Manufacturer, 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 stateinent :-
This invention relates to that class of machine in which two horizontal rubber
covered rollers are employed between which the knife blades are cleaned and is
designed to provide means for guiding or adjusting the position of the blades when
near the ends of the rollers and for preventing the same from becoming locked and
causing injury to the rollers or from slipping out from between them.
It consists essentially in the combination with the rollers of a guide roller guide
bracket or flange attached to the frame or otherwise so placed that the knife blade
will come in contact with it when at the extreme edge of the roller and thus be
prevented slipping over the edge from between the rollers.
The invention will be fully described with reference to the accompanying
drawings.

Improvements in Knife Cleaning Machines.
I, FREDERICK WILLIAM FOLLOWS, of Gorton, in the County of Lancaster,

This invention relates to that class of machine in which two horizontal rubber

designed to provide means for guiding or adjusting the position of the blades when
near the ends of the rollers and for preventing the same from becoming locked and

It consists essentially in the combination with the rollers of a guide roller guide

The invention will be fully described with reference to the accompanying
drawings.

Fig. 4. Front elevation of part of machine showing a modified form of the
invention.
Fig. 5. Front elevation of another modification thereof.
The frame A the rollers B and the driving gear C are of the ordinary construction
in this class of machine.
To the frame A preferably at the front of the rollers B and at each end I attach
a small bracket D carrying a guide roller E the face of the guide roller E being in
a line with the end of the cleaning rollers B. I at present prefer to use two of
these guide rollers placed at the front of the machine as shown but if desired they
may be placed at the back or four guide rollers may be used two at the front and
two at the back. These guide rollers prevent the knife blade running out over the
ends or edges of the cleaning rollers.
Referring to the modification shown in Fig. 4. instead of guide rollers fixed guide
brackets E may be employed for the same purpose bolted or otherwise attached to
the frame of the machine.
Referring to Fig. 5. another modification is shown flanges on the ends of the roller
being substituted for the guide rollers and for the same purpose. These flanges may
be either on the top or bottom roller.
It will be obvious that any similar guiding device attached to the frame or roller
may be employed.

By this invention I shall ensure the more regular wear of the rollers and
prevent liability of the knife blade becoming locked and damaging or cutting the
roller.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a knife cleaning machine constructed with horizontal rollers between which
the knives are cleaned the combination with the cleaning rollers of guide rollers,
guide brackets, flanges or similar guiding device attached to the frame or roller
