PROVISIONAL SPECIFICATION.
Improvements in Root Cutters or Pulpers.
I, WILLIAM BRENTON, of East Cornwall Iron Works, Polbathic, St. Germans,
in the County of Cornwall, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to root cutters or pulpers and comprises the improvements
hereinafter described.
In carrying out my invention I provide a circular hopper or receptacle in which
the roots to be cut or pulped are placed and at the bottom of which is a rotating
disc or wheel carrying a series of knives or pulpers, the said disc being carried by
a shaft rotating in a bearing or support preferably formed in one piece with the
hopper and driven through the medium of suitable gearing.
Inside the hopper and above the disc is placed a series of division pieces designed
to prevent the roots from being carried around with the disc and to support them
whilst being cut or pulped. These division pieces are advantageously made
inclined or of V or W shape or in the form of a crescent so that the roots will be
rigidly held in the hollows of the division pieces whilst being cut or pulped and the
cutting up of the smaller pieces of the roots is ensured. Beneath the disc is
arranged a tray or shoot of galvanized iron or other material for conveying the
sliced or pulped material into a basket.
In some cases I arrange on the disc, in conjunction with the division pieces,
vertical cutters for dividing the slices cut off by the knives of the disc.

COMPLETE SPECIFICATION.
Improvements in Root Cutters or Pulpers.
I, WILLIAM BRENTON, of East Cornwall Iron Works, Polbathic, St. Germans,
in the County of Cornwall, 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 :-
My invention relates to root-cutters or pulpers and comprises the improvements
hereinafter described.
In carrying out my invention I provide a circular hopper or receptacle in which
the roots to be cut or pulped are placed and at the bottom of which is a rotating
disc or wheel carrying a series of knives or pulpers, the said disc being carried by
a shaft rotating in a bearing or support preferably formed in one piece with the
hopper and driven through the medium of suitable gearing.
Inside the hopper and above the disc is placed a series of division pieces designed
to prevent the roots from being carried around with the disc and to support
them whilst being cut or pulped. Beneath the disc is arranged a tray or shoot of
galvanized iron or other material for conveying the sliced or pulped material into
a basket.
In some cases I arrange on the disc in conjunction with the division pieces
vertical cutters for dividing the slices cut off by the knives of the disc.
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 central vertical section of my improved root-cutter or pulper; and,
Figure 2 is a section of the same on the line 2-2, Figure 1:

page_text: Figure 3 is a sectional view drawn to an enlarged scale of a portion of the cutter
or pulper disc and one of the division pieces:
Figures 4 and 5 are plan views of division pieces of a shape different from that
shewn in Figures 1 to 3.
C
Similar letters of reference indicate corresponding parts in the several figures.
a is the circular hopper which is supported upon legs b, b or upon a suitable
framing, and c is the pulper disc which is arranged to rotate horizontally at the
bottom of the hopper a.
The said disc c is secured to a shaft d rotating in a
sleeve or bearing e, such sleeve or bearing being carried by the division pieces f,f,
the said sleeve with the said division pieces being cast in one piece with the
hopper a.
Up
Upon the upper end of the shaft 6 is fixed a gear-wheel g which serves as a collar
to support the shaft d and disc c and with which engages a pinion h mounted upon
a shaft i carried at one end in a bearing j formed upon one side of the sleeve e and
at the other end in a bearing k formed in a bracket 7 secured to the side of the
hopper, the said shaft i having a crank-handle or a driving wheel m fixed thereon,
the rotation of which causes the rotation of the disc.
The division pieces f, f, of which any suitable number may be employed, are on
one side open and on the other side extended downwards in an inclined direction
towards the disc c so that, as the said disc rotates in the direction of the arrow,
Figure 2, the roots will be carried into what may be termed the sheds formed by
the division pieces and held therein so that as the disc c with the cutting or pulping
knives thereon rotates it will slice off pieces of the roots.
As shewn in Figures 1 and 2 the division pieces on the open side are represented
as being of an inverted V-shape but they may with advantage be made of a
W-shape as shewn in Figure 4, or of a crescent shape as shewn in Figure 5.
n, n are the knives upon the disc c, the said knives being of any suitable shape
for slicing or pulping and arranged with their cutting edges above the surface of
the disc, as shewn most clearly in Figure 3, and in conjunction with openings o, o
through which the pieces of root cut or sliced off can drop.
p is the shoot arranged upon the bottom of the hopper a and serving to direct the
pieces of root falling through the disc c into a basket or other receptacle.
to
9, 9 are the blades or cutters which I sometimes employ for dividing the slices
cut off by the knives n, n. In practice a series of such blades q, q are preferably
fixed to a plater arranged beneath the disc c and are adapted to project through
openings therein, and in order to adjust the height of the said blades q, q
correspond with the blades n, the said plate r is preferably adapted to be raised
and lowered by means of a screws arranged to be rotated in the disc by the
introduction of a key into a hole t in its upper end but prevented from moving
longitudinally.
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. A root-cutter or pulper having the cutting or pulping disc rotating horizontally
in the bottom of a circular hopper beneath division pieces inclined to form sheds
into which the roots to be cut or pulped will be carried as the disc rotates,
substantially as described.
2. In a root-cutter or pulper having a cutting disc and a series of division pieces as
described, the arrangement of vertical blades with or without means for adjusting
the same, substantially as described.
3. The manufacture and use of the improved root-cutter or pulper hereinbefore
described and illustrated in the accompanying drawings.
