PROVISIONAL SPECIFICATION.
Improvements in or connected with Machines for Cutting Roots.
We, HENRY BAMFORD, Senior, SAMUEL BRASSINGTON BAMFORD, HENRY BAMFORD,
Junior, and JOHN BAMFORD, carrying on business as Bamford & Sons, of Leighton
Iron Works, Uttoxeter, in the County of Stafford, Agricultural Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to root cutting machines of the kind intended for cutting
what are known as finger pieces and the object of our invention is to provide improved
means for fixing the knives or cutters proper more rigidly than heretofore.
According to our invention the knives or cutters, which are of angular shape having
cutting edges substantially in the form of a right angle and being adapted to fit
against corresponding holes through the disc, are each provided at each end with a
tongue which tongues are both riveted to the cutter disc by rivets or the like so that
they are more securely held against vibration or bending than cutters which are
secured at one end only.
In practice the said tongues are adapted to enter corresponding recesses in the
back of the cutter disc the sides of which recesses assist in supporting the cutters
against the strain put upon them when in use.
Instead of constructing the cutters with a tongue at each end they may be
constructed so that one tongue extends from the rear instead of from the end.
Although we have described our invention as applied to a disc machine it is to be
understood that it can also be applied to a machine wherein a cutting barrel is
employed, as, for instance, in the well known "Gardner" cutter.

COMPLETE SPECIFICATION.
Improvements in or connected with Machines for Cutting Roots.
We, HENRY BAMFORD, Senior, SAMUEL BRASSINGTON BAMFORD, HENRY BAMFORD,
Junior, and JOHN BAMFORD, carrying on business as Bamford & Sons, of Leighton
Iron Works, Uttoxeter, in the County of Stafford, Agricultural Engineers, 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 :-
Our invention relates to root cutting machines of the kind intended for cutting
what are known as finger pieces and the object of our invention is to provide
improved means for fixing the knives or cutters proper more rigidly than heretofore.

page_text: According to our invention the knives or cutters, which are of angular shape,
having cutting edges substantially in the form of a right angle, and adapted to fit
against corresponding holes through the disc, are each provided at each end with a
tongue which tongues are both fixed to the cutter disc by rivets or the like so that
they are more securely held against vibration or bending than cutters which are
secured at one end only.
In practice the said tongues lie in corresponding recesses in the back of the cutter
dise the sides of which recesses assist in supporting the cutters against the strain put
upon them when in use.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 shews in rear elevation a portion of a cutting disc having the cutters
constructed and applied in accordance with our invention:
Figure 2 is a section on the line 2-2 Figure 1 drawn to a larger scale than the
said Figure; and,
Figure 3 is a section on the line 3-3 Figure 1 drawn to the same scale as
Figure 2:
Figures 4 and 5 are respectively an edge view and a rear view of one of the cutters
detached.
a is the cutting disc having formed in it a series of openings b, b in conjunction
with which the cutters are arranged in a well known manner.
c, c are our improved cutters and d, d are the tongues formed at the ends of the
same the said tongues when the cutters are placed in proper position relatively with
the openings b, b lying in the recesses e, e formed upon the back of the cutter disc
the said cutters being held in position by rivets f, for the like.
Instead of constructing the cutters with a tongue at each end as shewn in the
drawing they may be constructed so that one tongue extends from the rear of the
cutter instead of from the end as indicated by the dotted lines at g Figures 1 and 5.
Although we have described our invention as applied to a disc machine it is to be
understood that it can also be applied to a machine wherein a cutting barrel is
employed as for instance in the well known "Gardner" cutter.
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. A root cutting machine of the kind described having the cutters formed and
applied substantially in the manner set forth.
2. The manufacture and use of cutters for root cutting machines substantially in
the manner herein before described and illustrated in the accompanying drawing.
