I FRANÇOIS, ALCIDE BONNEFIN of 37 High Street, Islington in the County of
Middlesex, Engineer .do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR CUTTING UP SUGAR CANES, SORGHUM, MAIZE OR OTHER.
VEGETABLE SUBSTANCES" to be as follows:—
My invention relates to apparatus for cutting up sugar-canes, sorghum, maize or
other vegetable substances, and consists in combining for this purpose a series of
circular saws mounted upon a rotating shaft w.h a cradle or rack to which the
substances to be cut are supplied intermittently, the saws and cradle being so
arranged relatively to each other that the saws pass and work between the bars of
the cradle. The bars may be equal in number to the saws but one bar to 3 or 4
saws will generally be sufficient. The cutting action of the saws is preferably.
intermittent and this is effected by giving a reciprocating motion either to the saws
or to the cradle or to both saws and cradle; a reciprocating motion of the saws cau
be obtained by cranking or bending the shaft on which they are mounted or by
mounting the shaft in a frame to which reciprocating motion is imparted. Or, the
intermittent action of the saws can be obtained by making them oval or of varying
diameters the saw teeth being placed only at the periphery of the parts of largest.
diameter,
In connection with the circular saws and cradle I employ forks which are placed
between the circular saws so as to extricate the cut pieces from the spaces comprized
between the shaft of the saws and their periphery as the saws revolve.

I FRANÇOIS ALCIDE BONNEFIN, of 37 High Street, Islington in the County of
Middlesex, Engineer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR CUTTING UP SUGAR CANES, SORGHUM, MAIZE OR OTHER
VEGETABLE SUBSTANCES, 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 apparatus for cutting up sugar canes, sorghum, maize or
other vegetable substances and consists in combining for this purpose a series of
circular saws mounted upon, a rotating shaft with arcradle or rack to which the
substances to be cut are supplied intermittently, the saws and cradle being so
arranged relatively to each other that the saws pass and work, between the bars of
the cradle. The bars may be equal in number to the saws but one bar to 3.or 4
saws, will generally, be sufficient. The cutting action of the saws, is, preferably
intermittent and this is effected by giving a reciprocating motion either to the saws
or to the cradle or to both saws and cradle; a reciprocating motion of the saws can'
*be obtained by cranking or bending the shaft on which they are mounted or by
nounting the shaft in a frame to which reciprocating motion is imparted. Or, tho
intermittent action of the saws can be obtained by mounting the saws excentrically
on their shaft or by making them oval, or of varying diameters, the saw teeth
"being placed only at the periphery of the parts of largest diameter..
'
In connection with the circular saws and cradle I employ forks which are placed
between the circular saws so as to extricate the cut pieces from the spaces.comprised
between the shaft of the saws and their periphery as the saws revolve.
In the annexed drawings I represent by way of example a construction of
apparatus in which the saws are mounted in a framento which a reciprocating
motion is imparted.. Figure 1 is a sido elevation and Figure 2. a front elevation.
a is the cradle which in. this modification is fixed. b, b are the circular saws; they.
are mounted on a shaft c to which rotation is imparted by a belted from the
driving shaft e. The saw shaft c is carried in a frame f suspended from the shaft e
and this frame with the saws receives a reciprocating.movement from the connect-
ing rod g which is actuated by a crank on the shaft which receives its motion by
a belt from the driving shaft e. k, kare forks preferably curved, as shown,
placed between the circular saws b, b so as to extricate the cut pieces from the
spaces comprised between the shaft of the saws and their periphery as the 'saws
revolve; these forks, in the modification shown, are fixed to the frame ƒ, and in all
cases their position relatively to the axis of the saws should be immovable.
"Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim, in respect of apparatus for cutting up sugar canes, sorghum, maize or other
vegetable substances, is
1. The combination, substantially as described, of a series of circular saws,
mounted on a rotating shaft with a cradle or rack for containing the substance to

that the saws pass and work between the bars of the cradle.
2. In a combination of the kind referred to in claim 1, the arranging of the
apparatus so that the cutting action of the saws shall be intermittent, substantially
as described.
3. The several arrangements of apparatus hereinbefore described.

4. The combination, with a series of circular saws and a cradle, of forks,
substantially as described, for extricating the cut pieces from the spaces comprised
between the shaft of the saws and their periphery as the saws revolve.
