In order to prepare the furze or other substance to be operated upon, the same
is in accordance with this Invention caused to pass between two metallic rollers,
constructed (by preference of steel) in the following manner :-A roller is formed,
either entire or in sections, the circumference or periphery being provided with
rings of serrated projections or teeth. Between each of the rings of teeth the
surface of the rollers is left in a smooth state, and the diameter of the smooth
portions is smaller than that of the serrated portions in such a manner that arcs
described by the teeth of the respective rollers may intersect each other, as herein-
after described. The other roller is constructed of the same dimensions and in the
same manner as the one lastly described, except that the serrated and smooth
surfaces alternate in inverse order to the one hereinbefore described. The said
rollers are respectively mounted on suitable axles, which are parallel to each other,
the same being placed in such proximity as will ensure the arcs described by the
apices of the teeth of one roller intersecting the arcs described by the apices of the

page_text: teeth of the other roller, so far as to be adjacent to the plain edges or peripheries
of the smooth portions thereof. The rollers, as above described, are then caused to
be actuated by any suitable gearing to ensure their being driven at a differential
rate of speed, the same revolving towards each other. In order to prevent the
choking or clogging of the rollers by the juice of the furze or other substance under 6
treatment a number of small plates or scrapers are pivoted on a rod, the ends of
such plates being in contact with the peripheries of the smooth portions of the
rollers and at the same time intersecting the circle described by the apices of
the serrated portions, thus preventing the rollers from becoming choked or
clogged.

Office on the 13th December 1879.
WILLIAM MCBRIDE and JAMES MACKENZIE, both of the City of Cork, in the
County of Cork, Ireland. "IMPROVEMENTS IN MACHINES FOR PREPARING FURZE
FOR FEEDING PURPOSES, AND FOR THE KIBBLING AND GRINDING OF MAIZE, BEANS,
PEAS, BARLEY, WHEAT, AND OTHER KINDS OF GRAIN AND SEED."
Our said Invention consists in improvements in machines for the preparation of
furze for feeding purposes, and for kibbling and grinding maize, beans, peas, barley,
wheat, and other kinds of grain and seed.
The machines constituting the subject of our said Invention are constructed as
follows: A roller, made either in one piece or in sections, is mounted in suitable
bearings, and round the circumference or periphery thereof are made rings of
serrated projections or teeth; between each of the said rings of teeth the surface is
left smooth, and such smooth portions are made of smaller diameter than the
serrated portions. The above described roller is hereinafter referred to as the front
masticating roller.
A second roller is provided, the same corresponding in dimensions and form with
that above described, the only difference being that the serrated and smooth
surfaces of the latter alternate in inverse order to those of the former. This second
roller is hereinafter referred to as the back masticating roller.
The said rollers are mounted on suitable axles, which are arranged parallel to
each other and in close proximity, so as to cause the serrated or toothed portions of
each roller to be adjacent to the smooth portions of the opposite roller, in such a
manner that the arc described by the apices of the teeth of the one will intersect
the arc described by the apices of the teeth of the other roller.
In some cases, instead of making those portions of the roller which are between
the rings of teeth smooth, as hereinbefore described, we make the same slightly
serrated.
In order to prevent the choking of the above described rollers by the juice of
the furze or other substance a number of small plates as scrapers are pivoted to a
rod which is parallel to the axles of the rollers. The upper ends of the said
Scrapers are arranged so as to come into contact with the smooth portions of the
rollers, thereby intersecting the arc of the circle described by the apices of the teeth
of each roller.
The rollers, constructed and arranged as hereinbefore described, are caused to
revolve by means of any suitable gearing at a differential speed, each roller turning
in a direction towards the opposite roller.
We will now proceed to refer to the accompanying Drawings, from which the
nature of our said Invention will be more clearly understood. Figure 1 is a side
elevation of a machine constructed in accordance with our said Invention; Figure 2
is a front elevation of the same, with a portion of the front cover removed for the
purpose of showing the front roller and scrapers; Figure 3 is a transverse section ;
Figure 4 is a plan of the masticating rollers; Figure 5 is a side elevation of the
latter and their respective scrapers; Figure 6 is a front elevation of the same; and
Figure 7 is a side elevation of one of the rollers, showing one of the smooth portions
and the position of the corresponding scraper. The same letters of reference
indicate like parts in the several Figures. A is the front masticating roller, and B
the scrapers thereof; F is the back masticating roller, the scrapers thereof being
shown at G; H is a stopper or feed board for the furze, which is drawn in to be
operated upon by the feed rollers D and E; C are revolving cutters for cutting the
furze into short lengths before it is passed between the masticating rollers A and F;
I indicates a hopper which is attached to the machine when the latter is employed

page_text: for the purpose of grinding and kibbling maize, corn, and other kinds of grain and
seed.
Having thus described and ascertained the nature of our said Invention, and the
manner in which it is to be performed, we would observe in conclusion that we do
not claim the several mechanical portions of the machine separate and apart from
each other; but what we consider novel and original and therefore claim as
constituting the Invention secured to us by the said hereinbefore in part recited
Letters Patent is,―
The construction and arrangement of the masticating rollers A and F and the
combination thereof with their respective series of scrapers B and G, substantially
as and for the purposes hereinbefore described and set forth.
In witness whereof, we, the said William M.Bride and James Mackenzie,
have hereunto set our hands and seals, this Sixth (6th) day of December, in
the year of our Lord One thousand eight hundred and seventy nine.
