Improvements in or Appertaining to Apparatus for Cutting Sugar
Canes and other like Plant Stems.
A communication from abroad by ROBERT MAURIN, of Donaldsonville, in the Parish
of Ascension, State of Louisiana, United States of America, Sugar Planter.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
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:
The present invention relates to apparatus for cutting sugar canes and other
like plant stems and consists in the construction, novel combination and adaptation
of parts, and the novelty will be fully understood from the following description
and claims when taken in connection with the annexed drawings in which :-
Figure 1 is a perspective view of the improved machine complete.
Figure 2 is a rear elevation of the same.
Figure 3 is a detail vertical side elevation of one of the adjustable auxiliary
cutter blades.
Figure 4 is a vertical end elevation of the same, and Figure is a detail view
of the transverse bar, showing the depending arms for the attachment of the
auxiliary cutter blades.
Referring, by letter to the said drawings, A indicates the draught beam of a
form such as employed on ordinary ploughs having a clevis at one end and
suitable handles at its opposite end.
To the forward portion of the beam A is attached a cutter B, secured in its
seat by a key and depending from the beam. In rear of this cutter is a roller C,
arranged in advance of the triangular blade or cutter which will be presently
described.
D indicates the cutter which is of a triangular form in outline and slightly
concavo-convex in cross section. This cutter is provided on its upper side with a
shield or guard E, composed of three vertical branches united in a triangular manner,
and surrounds the standard or braces.
N indicates the standard which is secured at its lower end to the cutter and the
rear wall of the shield as shown, and is secured about midway of its length to the rear
end of the draught beam, its upper portion being secured by a round or cross bar to
the handle beams.
G indicates the transverse beam or bar, which carries the depending arms at its ends
for the attachment of the auxiliary vertical cutter blades.
This transverse bar G is provided midway of its length with a bolt hole a, for the
passage of a bolt employed in attaching the said bar to the standard N as better shown
in Figure 2.
At its opposite ends the transverse bar is bent to form the depending arms K, which
are provided respectively with bolt holes for the attachment of the auxiliary vertical
knives.
H, indicates the auxiliary vertical knife blades, the same being better shown in
Figure 3.
These knives H are provided respectively with a central longitudinal slot P for
the passage of the bolts which secure them to the depending arms of the transverse
bar, and it will be readily apparent that through the medium of these slots P the
vertical knives are rendered adjustable.

page_text: Through the placement of these auxiliary vertical knives as has been described, and
the facility of their adjustment with respect to the side edges of the triangular cutter,
it will be readily seen that they will catch old stems of plants that pass along the
side edges of the triangular cutter and assist the latter in shaving or severing the
same.
O indicates an auxiliary standard which connects the triangular cutter with the
beam in advance of the main standard; and F indicates a brace rod which secures the
cutter to the beam between the main and auxiliary standards.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the sanie is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In an apparatus for cutting sugar canes and other like plant steins, the triangular
cutter B concavo-convex transversely as shown, in combination with the triangular
shield E, having the three vertical sides or branches and secured to the upper convex
side of the cutter at a distance from its marginal edges, the standard N, and the trans-
verse horizontal bar & secured to the rear side of said standard and having depending
arms for the attachment of the vertical knives, substantially as specified.
2. In an apparatus for cutting canes, the triangular cutter B, concavo-convex trans-
versely, in combination with the standard N and the transverse bar G secured thereto
at its rear side and having depending arms for the attachment of the vertical knives,
substantially as specified.
3. In an apparatus for cutting canes, the combination, with the triangular cutter B,
concavo-convex transversely, and the standard N, of the transverse bar (+ secured
thereto at its rear side and having depending arms for the attachment of the vertical
knives, substantially as specified.
4. In an apparatus for cutting canes, the combination with the triangular cutter,
concavo-convex transversely and the main standard of the transverse bar secured
thereto at its rear side and having depending arms for the attachment of the vertical
knives and the vertical knives having a longitudinal slot for the passage of the securing
bolts, whereby it may be adjusted upon the same, substantially as specified.
Dated this 21st day of February 1890.
