graters
Year: 1898

page_text: I, WILLIAM JAMISON CURRY, of Nanaimo, British Columbia, Canada, Gentle-
man, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to certain new and useful improvements in graters for
nutmegs, lemon rind and such like.
The invention has for its object the provision of a better class article of the
kind aforementioned at a very slightly increased cost; the provision of a grater
in which the roughened or serrated surface can be adapted for grating either fine
or coarser particles from any substance; the provision of a grater which can be
readily sharpened when required; and a device of the sort which will possess
advantages which will manifest themselves to those persons who use the grater.
A grater constructed in accordance with my improvements, comprises a piece of
sheet metal, curved to the well known form of the ordinary nutmeg grater, having
a series of slots of any desired pattern through its curved surface, and retaining
flanges on its edges.
Another member of the same shape fits the interior of the last, mentioned and
outer member, and has a series of serrated grating ridges, on its surface, which
are adapted to project through the slots of the outer member.
A strip of metal slid into the retaining flanges of the outer member keeps the
inner one in place. This strip of metal is provided with a spring-clip or locking
device to keep it in position, and has also a loop formed upon it to enable it to be
withdrawn.
When the inner member is removed, its teeth can be sharpened, and, when
required, another member can be substituted therefor having longer or shorter
teeth as desired.
The slots in the outer member are preferably, though not necessarily, larger
than required for the projection therethrough of the serrated ridges, and the
inner member is formed with openings for the passage of the grated substance
therethrough into the interior of the grater.

man, do hereby declare the nature of this invention and in what manner the same

following statement:―
This invention relates to graters of that class used for granulating substances
such as lemon rind, certain fruits, nutmegs etc.; the object of the invention being
to provide a grater in which the abrading points can be removed in order that
adherent particles can be removed and the grater be thoroughly cleaned, and
further, in which abrading surfaces or teeth of various degrees of coarseness may
be employed according to the nature of the substance to be grated and the size
of the grains it is desired to produce. Another object of the invention is to
provide a grater possessing the above mentioned advantages, which can be
readily stamped from sheet metal and consequently be cheaply produced.
Reference being had to the drawings hereunto annexed:
Fig. 1 is a view, in perspective of my improved grater; Fig. 2 is a cross section
therethrough; Figs. 3 and 4 are detail views of some of its parts; Figs. 5 and 6
are detail views shewing an alternative method of combining the two principal
members of the grater.
The grater comprises the outer shell 1 consisting of a piece of sheet metal,
curved as shewn, formed with inturned flanges 2, and a series of apertures 3 which
may be of any suitable shape or configuration.
The inner member comprises a piece of sheet metal curved to conform to the
inner surface of the outer member, and having its surface severed at intervals to
form tongues 4 which are bent upwardly and serrated to form abrading teeth 5.
The inner member is retained within the outer member by means of a plate 6
which is inserted between the flanges 2 and the edges of the inner member as
shewn clearly in Figs. 1 and 2. In order to retain the plate in place it is prefer-
ably indented as shewn at 8, and which indentations coincide and spring into
similar indentations 9 on the flanges 2 when the plate is inserted to its fullest
extent, and its further movement arrested by the stops 10, which consist of
upwardly bent projections on the inner end of the plate 6. Said plate is also
formed with an eye 7 by means of which it can be withdrawn, or the grater be
suspended when out of use.
When inner members having tongues projecting to different degrees to provide
abrading teeth or edges suitable for hard or soft substances respectively, it is
essential that more or less space be allowed between the edges of the inner
member and the flanges, and that this space be taken up by the locking-plate
when inserted in order to keep the two members in close contact. This is effected
by corrugating the edges of the plate as shewn at 11, Fig. 4, so as to render the
edges 12 of a springy nature so that they will rise to take up any looseness or
space. In order that the corrugated portions of the plate may be easily inserted
between the flanges and the edges of the inner member, the former are corrugated
from their ends 13 to a point at 14 so that the corrugations 11 gradually ride
out of the corrugations in the flanges onto the upper surface thereof, as shewn
at 15.
In Figs. 5 and 6 the outer member 1 is shewn as having one end flanged over
as shewn at 16 and its other end formed with a spring-strip 17 formed with a
loop 18 and stops 19. On end of the inner member 2 is retained by the inturned
flange 16 and its other end has a cross-piece 20 which, when the member 2 is in
position, is sprung within the strip 17 and rests under the stops 19. To remove
the member 2, the loop 18 is drawn outwardly until the stops 19 clear the edge
of the cross-strip 20.
The members and locking-plate-or, as described with reference to Figs. 5
and 6, the members only-having been assembled the grater may be used in the
ordinary and well known manner; the granulated grains passing through the
coincident apertures in the two members to the plate 6 from whence it may be
shaken or permitted to fall into any suitable receptacle. It will be understood,
of course, that the tongues 4 project through the apertures 3 more or less accord-
ing to the degree of coarseness required.

page_text: 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:-
1. A grater having interchangeable abrading members, substantially as and
for the purposes herein before set forth and illustrated in the drawings hereunto
annexed.
2. A grater comprising an outer shell or member provided with a series of
openings in its body, a second shell or member adapted to fit within the outer
shell or member and having teeth or abrading tongues or parts adapted to project
through the openings aforementioned, and openings formed in the inner member
coincident with the openings in the outer member, and suitable means such as a
plate adapted for insertion between longitudinal flanges on the outer member
and the edges of the inner member, for retaining the members in contact, all
substantially as and for the purposes herein before set forth, and illustrated in the
drawings hereunto annexed.
3. A grater comprising an outer shell or member, a flange inturned at one end
of said member adapted to retain one end of an inner member, a spring strip
secured to the other end of said outer member and having stops thereon adapted
to support a cross-strip on the inner member, abrading portions on the inner
member adapted to project through the aforesaid openings of the outer member,
all substantially as and for the purposes herein before set forth and illustrated
in the drawings hereunto annexed.
