PROVISIONAL SPECIFICATION.
Improvements in connection with Root Pulping or Grating
Machines.
I PHILIP PIERCE, Agricultural Engineer, Mill Road Iron Works, Wexford,
Ireland, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that type of machines for cutting
roots in which discs are used having blades or cutters and the object of this
invention is to prevent the clogging or bridging of the roots in the hopper.
For this purpose I mount upon the shaft carrying the disc a cam preferably of
such a length as to occupy the space between the cutting side of the disc and the
opposite side of the framing and I construct the end grating of the hopper of
such a form that the lower end of said grating shall pass diagonally over the said
cam. By this means I provide a gradually feeding incline directly over the cam,
and the roots being acted upon by the lifting action of the cam are from time to
time sufficiently displaced and agitated to cause them to slide continually down-
wards; and owing to the formation of the end of the grating as herebefore
mentioned the tendency of the roots is to move towards the cutting disc
and thus prevent the inconvenience caused by the choking or bridging of the
hopper.

Improvements in connection with Root Pulping or Grating
Machines.
I PHILIP PIERCE, Agricultural Engineer, Mill Road Iron Works, Wexford,.
Ireland, 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 type of machines for cutting roots
in which discs are used having blades or cutters and the object of this invention is
to prevent the clogging or bridging of the roots in the hopper.
And in order that my invention may be fully understood I submit the following
drawings:
Fig. A is a part sectional elevation of a root cutter as will serve to illustrate the
improvements of my invention attached thereto.
Fig. B is a plan of same.
Fig. C is an enlarged sectional view of the cam and the end grating of the
hopper.
Fig. D is a plan of same.
I construct the machine in the usual manner.
1 is the frame. 2 is the shaft carrying the disc. 3 is the disc on which the
knives are attached. 4 is the cam. 5 is the end grating of the hopper. 6 is the toe
piece of the hopper. 7 is the end plate of the hopper.

page_text: For the purpose of this invention I mount upon the shaft 2 the cam 4
preferably of such a length as to occupy the space between the disc 3 and the
opposite side of the frame 1 and I construct the end grating of the hopper 5
of such a form that the lower end of the said grating shall pass diagonally over
the cam 4.
It will be observed that the lower end of grating 5 will form in conjunction
with the other end plate of the hopper 7 a gradually opening or feeding
mouth whose largest space will be on the side nearest to the cutter disc 3 and
the roots being acted upon by the lifting action of the cam 4 as it revolves with
the shaft 2 a displacement of the roots takes place at this (the usual choking)
point of the hopper, and are caused to slide continually downwards and towards
the cutter disc 3.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
In root cutters the combination of the cam revolving with a cutter disc, and
the diagonally shaped grating of the hopper passing over said cam for the purpose
specified.
