COMPLETE SPECIFICATION.
Improvements in Graters.
EVANGELINE GILMORE, of the City of Hamilton, in the County of Wentworth,
in the Province of Ontario, Dominion of Canada, Lady, 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:-
My invention relates to improvements in graters for grating vegetables and fruit,
either dry or green, and consists of a light plate.its face being either of a convex
or straight plane having a number of series of raised cutters with apertures through
the upper parts thereof and forming a part of said grater plate.
These raised cutters having apertures may be of various shapes, providing that
the cutting part alone rises, or projects, above the smooth surface or plane of the
grater and the sides and lower parts slope and incline gradually to the face of the
grater.
The objects of my improvements are, first, to provide a grater that is capable of
reducing to small particles various kinds of vegetables, fruits and spices, second to
provide an effective clean cutting grater capable of grating at each downward
stroke only, this being very important, and third, to afford facilities for the proper
and easy construction of a grater having circular apertures the lower semi-circular
parts of which forms the cutting edges of the grater.
In the drawing similar letters refer to similar parts throughout the several
views.
Figure 1, is a face clevation of my improved grater showing circular apertures
in relative position to the raised cutters, the lower semi-circular parts of said
apertures forming the cutting edges the lowest part being the highest.
Figure 2, is a sectional elevation of the same through vertical line 2, 2, and centre
of cutters.
Figure 3, is a section of Figure 1, through the horizontal line X, X, and
Figure 4, is a section of Figure 1, through the horizontal line V. V.
-
All these distinctive views are very much enlarged in order to show more fully
and definitely the constructive formation of the raised cutters, the cutting edges being
the upper parts of the raised cutters formed by the lower part of the apertures, the
downward stroke only, being effective when grating.
In the drawing the plate of the grater is indicated by the letter A, the face of
which may be of a convex formation, or a level plane. The raised graters, or
cutters, the highest part, or apex, of which is indicated by B, the sloping sides by C,
and the upper slopes by D..
E, are the circular apertures, the lower half through the cutters, the lower
semi-circular part of each aperture, rising gradually from the face of the grater
plate to the apex of the cutter, and forming the cutting edge thereof.
In construction these apertures are preferably of circular shape to assist
materially in the construction being drilled, or punched in the plate, and after-
wards the raised cutters are stamped from the rear of the plate, forming rear
depressions which conform in shape to the cutters, the thickness being equal
throughout, the apertures in conjunction with the said depressions in rear of the
plate forms full and ample egress for the grated material. The central vertical
fine F, of each cutter from the apex B, downwards, is one gradual slope to the
face of the plate, said face in general acting as guide when grating. The horizontal
side lines H, also slope gradually from the apex of the cutters to the face of the

page_text: plate of grater, therefore it will be perceived that the actual grater, is that part
formed in the raised cutters by the lower semi-circular part of the apertures, the
said cutting parts being raised on an incline above the plane of the grater, the
highest part being the apex B, as previously mentioned, all other parts sloping
gradually therefrom to the face of the plate, therefore giving strength and firmness
to the whole grater.
The rear of the grater plate has depressions which conform in shape to the face
thereof, these depressions with the apertures form full and ample openings for the
grated material to drop through.
The inclined cutting edges rising from the plane or guide face of the grater
plate and forming an apex or highest part of the apertures, produce a uniform
shear cutting of the material and a final clean severance, this being very important
in grating.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. A grater plate constructed and formed with a number of series of cutters,
raised above the face thereof, the sides and lower part of each said cutter sloping
from the apex to the face of the plate and each cutter having an aperture substan-
tially as described and set forth.
2nd. In a grater, a plate having a number of series of raised cutters forming a
straight and gradual slope from their highest part or apex B, to the face of their
plate, the rear of each cutter conforming in shape thereto and having apertures, for
egress of grated material, substantially as described and set forth.
3rd. A metallic plate formed with a number of series of raised and projecting
cutters the rear of the plate conforming thereto, the sides and lower part of the
cutters gradually sloping from their highest part to the face, and apertures through
said plate forming clean cutting edges to said cutters, substantially as described and
set forth..
