PROVISIONAL SPECIFICATION.
Improvements in Root Cutters or Pulpers.
We, EDWARD CHRISTOPHER BLACKSTONE, Managing Director of Blackstone
and Company, Limited, of the Rutland Engineer Works, Stamford, in the County
of Lincoln, Engineers, and JAMES KELLY Senior, and JAMES JOSEPH KELLY
Junior, trading as James Kelly & Son, of St. Canices Place, Kilkenny, in the
County of Kilkenny, Ireland, Engineers and Machinists, do hereby declare the
nature of this invention to be as follows:-
This invention relates to root cutters or pulpers of that kind in which a rotary
disc is employed having two sets of knives or cutters, one of which sets serves for
slicing, pulping or grating, the roots and the other set (hereinafter referred to as
fingers."
the finger cutters) for dividing the slices into strips or
"
In machines of this class as heretofore constructed the finger cutters have
frequently been made movable so as to allow of their being withdrawn out of
action to permit of slices being cut. The means for effecting such movement,
however, have usually been difficult to operate and liable to be rendered inoperative
owing to the corrosion produced by the juices of the roots cut.
Now the object of this invention is to arrange the finger cutters and the means
for moving them in such a manner that they can instantaneously be put into or out
of action and that the parts are less liable to become corroded than heretofore.
In carrying out our invention we fix the finger cutters to a block or blocks
arranged behind the pulper disc and connected to or formed in one piece with a
hollow boss adapted to slide over or upon the boss of the pulper disc, a key or
feather or a square on the shaft serving to cause the block or blocks to rotate with
the disc. This hollow boss has formed in it at one end a groove with which the
bifurcated end of a rod or a lever may engage to permit of moving the said boss
with the finger cutters towards and away from the pulper disc. A spring may
also be arranged between the two bosses to normally hold the knives in their
inoperative position or to bear upon the boss to press the finger cutters into
their operative position, the lever or rod being in either case arranged to permit of
its being fixed to retain the finger cutters in the required position against the
pressure of the spring. It is to be understood that our invention is also applicable
to machines for slicing and pulping or slicing and grating roots.

page_text: County of Kilkenny,, Ireland, Engineers and Machinists, 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 root cutters or pulpers of that kind in which a rotary

slicing, pulping or grating the roots and the other set (hereinafter referred to as
the finger cutters) for dividing the slices into strips or fingers."

In machines of this. class as heretofore constructed the finger-cutters have
frequently been made movable so as to allow of their being withdrawn out of action
to permit of slices being cut. The means for effecting such movement, however,
have usually been difficult to operate and liable to be rendered inoperative owing
to the corrison produced by the juices of the roots cut.
Now the object of this invention is to arrange the finger-cutters and the means
for moving them in such a manner that they can instantaneously be put into or out
of action and that the parts are less liable to become corroded than heretofore.
In carrying out our invention we fix the finger-cutters to a block or blocks
arranged behind the pulper disc and connected to or formed in one piece with a
hollow boss adapted to slide over or upon the boss of the pulper disc.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a sectional front elevation:
Figure 2 is a sectional side elevation shewing the finger-cutters in position for
operation and,
Figure 3 is a sectional view similar to part of Figure 2 but shewing the finger-
outters in their inoperative position.
a is the frame or stand of the machine, and 6 is the cutting disc mounted on the
shaft c. dis the shield covering the said disc (the said shield as shewn in Figure 1
being partly broken away to shew the disc behind it) and e is the hopper.
ff are the usual cutters or slicers carried on the disc band.g, g are our finger-
cutters adapted to pass through holes g', g' in the said disc.
h, are the arms or blocks to which the said finger-cutters are fixed, openings
being formed in the said arms to receive the ends of the finger-cutters and wedge-
pieces or cotters i, i. The said arms h, h.as.shewn are formed in one piece with a
hollow boss which slides upon the boss of the disc b. In order to cause the said
boss with its arms to rotate with the disc, holes are formed in the said arms through
which guide-pins.k, k fixed to the disc b are inserted.
With this arrangement it will be understood that when the boss with its arms
is moved towards the disc (for instance by the knob j fixed to the boss j) the
finger-cutters 9 will be moved into contact with the knives or cutters f, f, as
abewn in Figure 2, so that the slices cut by the knives will be divided into fingers;
when, however, the finger-cutters are moved back to the position shewn in Figure 3,
the slices cut by the knives ff will be undivided.
In order to retain the finger-cutters in either of the two positions, we form on
the boss ja rib and on the guard d over the disc we pivot at m a locking-plate n
cu one or the other side of which the rib bears according to the position of the
finger-cutters.
Instead of moving the finger-cutters by means of a knob as hereinbefore
described, we may arrange a lever having bifurcated end engaging in a groove
in the boss j, and in this case the locking-plate n is unnecessary as means may
be provided for locking the bifurcated lever in either of its two positions.
It is to be understood that our invention is also applicable to machines for
slicing and pulping or slicing and grating roots.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :--
1. In a root cutting or pulping machine having two sets of knives, or cutters,

for dividing the
viz., one set for slicing and the other set termed "finger-cutters
slices, mounting the finger-cutters upon blocks connected to a hollow boss adapted
to slide upon the boss of the pulper disc whereby the said finger-cutters can be
readily moved into or out of their operative position, substantially as described.
2. In a root cutter or pulper having two sets of knives or cutters arranged in
the manner referred to in the preceding claiming clause, means substantially as
described for moving the finger-cutters relatively with slicing cutters.
3. The manufacture and use of the improved root cutting or pulping machine
hereinbefore described and illustrated in the accompanying drawings.
