PROVISIONAL SPECIFICATION.
Improvements in Root Cutters or Pulpers.
I, EDWARD CHRISTOPHER BLACKSTONE, of The Rutland Engineering Works,
Stamford, in the County of Lincoln, Agricultural Engineer, do hereby declare the
nature of this invention to be as follows:-
:-
This invention relates to improvements in that class of root cutters or pulpers.
which have a horizontal knife or cutter carrying disc and inclined plates for holding
the root against the revolving knives or cutters.
•
According to my invention I make the inclined plates with a number of crescent
shaped corrugations (not less than three) and formed with knife edges, by means of
which edges the root is securely held against the revolving knives and prevented
from rolling, no matter whether the roots be large or small.
In order to provide for the easy removal of the knife or cutter disc so as to allow
of changing the disc, I screw thread the lower end of the spindle, which screws
into a screw threaded hole in the boss of the disc so that, by turning the disc
backwards, it will be released from the spindle and be received upon ledges or cross
bars provided for the purpose.

Improvements in Root Cutters of I uspore
I, EDWARD CHRISTOPHER BLACKSTONE, of The Rutland Engineering Works,
Stamford, in the County of Lincoln, Agricultural Engineer, 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 improvements in that class of root cutters or pulpers
which have a horizontal knife or cutter carrying disc and inclined plates for holding
the roots against the revolving knives or cutters.
According to my invention I inaké the inclined plates with a number of crescent
shaped corrugations (not less than three) and formed with knife edges, by means of
which edges the root is securely held against the revolving knives and prevented
from rolling, no matter whether the roots be large or small.
In order to provide for the easy removal of the knife or cutter disc so as to allow
of changing the same, I screw thread the lower end of the spindle which screws
into a screw threaded hole in the boss of the disc so that by turning the disc back-
wards, it will be released from the spindle and be received upon ledges or cross
bars provided for the purpose.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a plan of my improved root cutter or pulper:
Figure 2 is a vertical section; and,
0 T 1

page_text: a is the framing of the machine; b the hopper or receptacle into which the roots
to be cut are placed, and c the cutter disc which is arranged beneath the said
hopper so as to form the bottom of the same and which is provided with any
suitable form of cutting knives d, d.
e, e are the inclined plates and fis the central boss or bracket in which the
spindle g, carrying the disc c, has bearings. As shewn in the drawings, the said
boss or bracket is supported by the inclined plates. e, e; the hopper b, the inclined
plates e, e and the bracket f being formed in a single casting. If desired, however,
the bracket f may be supported upon the hopper by any suitable means, and the
inclined plates e, e may be made separate and attached to the hopper and the
bracket by bolts or other devices.
Each of the plates e, e, which is preferably shaped in vertical section, as shewn
in Figure 3, so as to firmly hold the last portions of the roots to be cut, is
corrugated and formed with knife edges at e', which knife edges serve to prevent
the roots, bearing against the same, from turning around whilst the knife is acting,
against them.
h is the driving shaft carrying the fly wheel the said shaft at one end being
supported in a bearing; at the edge of the hopper, and at the other end in the
bracket; the said shaft also carrying the pinion & engaging with the bevel wheel Z
at the upper end of the shaft g. The wheel also serves as a collar to prevent the
weight of the disc c from drawing the shaft out of its bearings. As hereinbefore
stated the lower end of the shaft g is screwed into the hub of the disc c the screw
threads being so arranged that when the machine is operating, the tendency will be
for the disc to be screwed onto the said shaft. To remove the disc from the spindle
it is only necessary to hold the said disc against rotation and to turn the fly wheel
in the reverse direction to that in which it is rotated when working the machine.
c, care the ledges or cross bars for receiving and supporting the disc c when
released from the spindle g, the said ledges being arranged as shewn so that the
said disc can then be drawn out of the machine.
"
m is a shoot which serves to direct the pieces of root dropping through the
disc c, into a basket or vessel placed underneath the framing.
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 :-
1. In a root cutter or pulper having a horizontally rotating cutter disc a series of
corrugated inclined plates having knife edges formed on the surface against which
the roots hear, substantially as described.
2. The manufacture and use of the improved root cutter or pulper hereinbefore
described and illustrated in the accompanying drawings.
