The improvements consist of a receptacle open at one end or side, and furnished
with a perforated, stabbed, or raised grating surface on one or more sides, against
which is to be worked another receptacle furnished with a holder or device backed
by a spring for holding and keeping in position against the surface of the grater
the object to be grated, the receptacle last referred to being worked in a pair of
grooves formed on the edges of the side or sides. The object being to grate the
nut or other matter away to the last and so prevent waste; the whole can be made
of metal, or metal and wood or other convenient substance combined."

"IMPROVEMENTS IN GRATERS." A communication from abroad by Martin
Vaubureu Bligh, of Boulogne sur Mer, France.
The object of this Invention is to provide a simple and cheap implement for
grating nutmegs, ginger, and similar substances without waste. This Invention
consists in the combination of a perforated sheet grating similar to those used in
other graters, with a movable holder backed by a spring for holding and pressing
against the surface of the grating the object to be grated, the said holder being
guided parallel with the grating by a pair of grooves formed along the sides of
the latter.
The accompanying Drawings, which show an example of an improved nutmeg
grater, will serve to explain more clearly the nature of this Invention and the
details of construction, Fig. 1 being a front view; Fig. 2, a plan; Fig: 3, a vertical
section; Fig. 4, a side view; and Fig. 5, a bottom view.
A represents the body of the grater made of sheet metal, and closed on all sides
except the bottom end, through which the ground material is discharged; B is the
grating made of perforated flat sheet metal similar to those used in other graters;
b are the perforations; C, flanges bent round to form grooves which guide the
nutmeg holder parallel to the grating surface; D is a cap over the cylindrical
nutmeg receptacle, and secured to the latter by a pin d' and elbow slot d; E is a
helical spring attached at one end to the inside of the cap D, and exerting an
elastic pressure on the nutmeg or similar article to be grated; F is a button or
disc which forms an abutment for the spring; G is a nutmeg; and H, a hook for
suspending the grater.
The implement is used by placing a nutmeg or similar object in the holder,
putting on the cap D, and carrying the holder forward and backward along the
grating, whereby the nutmeg or similar object is pressed against the grating and
scraped.
In witness whereof, I, the said James Govier Thresher, have hereunto set
