EVANGELINE GILMORE, of the City of Hamilton, in the County of Went-
worth, in the Province of Ontario, Dominion of Canada, Lady, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in a grater, the face of which may be
either flat or convex, having a number of series of raised cutters, or graters, which
form, and are a part of said grater, and formed with apertures through each said
cutter, these raised cutters are of an acute angle in shape, the root or point of
angle being the lower part, of each cutter, as shown, this being preferable
to any other design, the angle cutting part of each of the series of graters
alone being raised above the plane or face of the grater plate, and having sloping
sides.
When grating, the downward stroke alone is effective.
The objects of my improvements are, to provide a grater that will grate, or
reduce, or to pulverise various kinds of spices, and more especially to reduce to
pulp, or small parts, various kinds of vegetables or fruit, such as carrots, potatoes,
lemons and oranges in a speedy and perfect manner, the said apertures of the
raised cutter remaining open and free.
Figure 1, is a face elevation of a large and very open grater, the lower part of
which is broken away, showing a number of the raised graters, or cutters, their
cutting parts or edges being formed by their apertures.
Figure 2, is a sectional view of the same, through the horizontal line X, X.
Figure 3, is a sectional view of Figure 1, through the vertical line V, V.
Figure 4, is a face elevation of a piece of the grater, on an enlarged scale, to
show the constructive formation of one of a series of the raised cutters with
aperture.
In the drawing A, is the light metallic grater plate which may be of convex
form, or perfectly flat, as delineated, B, are the raised graters, or cutters, which
form a part of said plate and C, are the apertures, as shown when punched or
stamped out, thus forming the angled shaped cutters.
It will be observed, that in order to grate with this device, the vegetable or
fruit. must be brought downwards upon the grater, therefore engaging with the
several cutters.
On account of the particular shape and raised construction of the cutters, the
same cuts very fine and clean, without any improper clogging or obstruction of
the apertures or openings, C, this being very important.
The most important part is the acute angle cutters the projecting or raised
cutting part of which must be raised above the face of the grater plate, without
the least obstruction, the outer part 2, of each cutter slightly sloping to the face
of the plate, and the outer part 3, of the angle cutters gradually slope to the face
of the plate, therefore leaving the edges of the angle cutters free, the roots of the
angles being the lower part.
These upper, and side sloping parts of the angle cutters, give firmness and
strength to the same, and also to the grater plate.
This plate with its raised cutters and apertures is formed, by means of punching
into this particular shape, for grating purposes, the rear of the plate conforming in

page_text: shape to its face, as delineated, the said apertures C, being through the raised
parts and sloping rearwards in conformity therewith as defined.

EVANGELINE GILMORE of the City of Hamilton, in the County of Went-
worth, 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,
reference being made to the drawing left with the Provisional Specification:-
My invention relates to improvements in a grater, the face of which
either flat or convex, having a number of series of raised cutters, or graters, which
form, and are a part of said grater, and formed with apertures through each said
cutter, these raised cutters are of an acute angle in shape, the root or point of
angle being the lower part, of each cutter, as shown, this being preferable
to any other design, the angle cutting part of each of the series of graters
alone being raised above the plane or face of the grater plate, and having sloping
sides.
When grating, the downward stroke alone is effective.
The objects of my improvements are, to provide a grater that will grate, or
reduce, or to pulverise various kinds of spices, and more especially to reduce to
pulp, or small parts, various kinds of vegetables or fruit, such as carrots, potatoes,
lemons and oranges in a speedy and perfect manner, the said apertures of the raised
cutter remaining open and free.
Figure 1, is a face elevation of a large and very open grater, the lower part of
which is broken away, showing a number of the raised graters, or cutters, their
cutting parts or edges being formed by their apertures.
Figure 2, is a sectional view of the same, through the horizontal line X, X.
Figure 3, is a sectional view of Figure 1, through the vertical line V, V.
Figure 4, is a face elevation of a piece of the grater, on an enlarged scale,
to show the constructive formation of one of a series of the raised cutters with
aperture.
In the drawing A, is the light metallic grater plate which may be of convex
form, or perfectly flat, as delineated, B, are the raised graters, or cutters, which
form a part of said plate, and C, are the apertures, as shown when puuched or
stamped out, thus forming the angled shaped cutters.
It will be observed, that in order to grate with this device, the vegetable or
fruit must be brought downwards upon the grater, therefore engaging with the
several cutters.
On account of the particular shape and raised construction of the cutters, the
same cuts very fine and clean, without any improper clogging or obstruction of
the apertures or openings, C, this being very important.
The most important part is the acute angle cutters, the projecting or raised
cutting part of which must be raised above the face of the grater plate, without
the least obstruction, the outer part 2, of each cutter slightly sloping to the face of
the plate, and the outer part 3, of the angle cutters gradually slope to the face
of the plate, therefore leaving the edges of the angle cutters free, the roots of the
angles being the lower part.
These upper, and side sloping parts of the angle cutters, give firmness and
strength to the same, and also to the grater plate.
This plate with its raised cutters and apertures is formed, by means of punching

page_text: into this particular shape, for grating purposes, the rear of the plate conforming in
shape to its face, as delineated, the said apertures C, being through the raised
parts and sloping rearwards in conformity therewith as defined.
The double inclined straight cutting edges rising from the plane of the plate and
meeting in an apex at the rear end of the perforations thereby producing a uniform
shear cutting of the material, and a final clean severance of the shaving at the
rear edge.
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 is :-
In a grater, the metallic plate, having punched through it the substantially
triangular apertures C, each aperture having the raised lateral inclined cutting
edges, rising from the receiving end toward and joining at the rear or apex of the
triangle, to give a shear cut and a clean final severance of the grated material,
substantially as set forth.
