I, EDWARD JOHN ADAMS of 16 Broomhall Street Sheffield Yorkshire, Physician
and Surgeon do hereby declare the nature of this invention to be as follows:-
My Invention consists of an outer shell or cylinder of tin or other suitable metal
or substance, with a moveable or fixed bottom with perforations, or holes to allow the
substance when grated or rasped to pass through. At the sides of the outer shell or
cylinder, are two or more openings to which are attached or fixed tube like processes
with openings capable of admitting the substance to be grated and also opening on to
the grater hereafter described.
In the interior of the aforesaid tube like processes is a spring or springs or other
suitable means by which wooden blocks or similar contrivance is made use of for
pressing forward toward the surface of the grater the substance to be grated or
rasped.
The beforementioned blocks or similar contrivance are withdrawn a sufficient.
distance to admit of the substance to be grated being introduced when the blocks or
similar contrivance is released.
In the inner portion of the outer shell or cylinder a grater or rasper is so constructed
as to be capable of being revolved or rotated.
The inner portion is so made as to admit of being removed, that the gratings may
be the more conveniently emptied or for the purpose of cleansing the apparatus. Thus
two or more nutmegs or other substances can be grated or rasped at the same time,
and more effectually and economically than by the ordinary methods now in use, thus
effecting a saving of time and material.

An Apparatus for Grating or Rasping Nutmegs or similar
Substances.
I EDWARD JOHN ADAMS, of 16, Broomhall Street Sheffield, in the County of
Yorkshire, Physician and Surgeon, 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 consists of an outer cell or cylinder of tin or other suitable metal
or substance, with a moveable or fixed bottom with perforations or holes to allow
the substance grated or rasped to pass through.
At the sides of the outer cell or cylinder are two or more openings to which are
attached or fixed tube like processes with openings capable of admitting the substance
to be grated, and also opening on to the grater, hereinafter described.
In the interior of the aforesaid tube like processes is a spring or springs or other
suitable means by which wooden blocks or similar contrivances are made use of for
pressing forward toward the surface of the grater the substance to be grated or
rasped.
The before mentioned blocks or similar contrivances are withdrawn a sufficient
distance to admit of the substance to be grated being introduced when the blocks or
similar contrivance is released.
In the inner portion of the outer cylinder or shell, a cylindrical grater or rasper is so
constructed as to be capable of being revolved or rotated.
The inner portion is so made as to admit of being removed that the gratings may
be more conveniently emptied, or for the purpose of cleansing the apparatus.
Thus two or more nutmegs or similar substances can be grated or rasped at the
same time more effectually and economically than by the ordinary methods now in use;
thus effecting a saving of time and material.
DESCRIPTION OF DRAWINGS.
Fig. I, represents a vertical section showing the principle parts of an apparatus
for expeditiously and economically grating or rasping nutmegs or similar substances.
It consists of an outer cell or cylinder A, of tin or other suitable metal or substance,
with a fixed open bottom B, to allow the substance when grated or rasped to pass
through. At the sides of the outer shell or cylinder A. are two openings or tubes C. C.
projecting at right angles to the outer shell or cylinder A. and attached thereto,
these tubes or openings C. C. are capable of admitting the substance H, to be grated
or rasped. In the interior of the inner tube C, but attached to the outer tube D. is
a spring E, and cup and spindle F. F. these are selfacting and press forward toward
the surface of the grater G, the substance to be grated or rasped H.
The before mentioned spring, cup and spindle with outer tubes D. are drawn off the
inner tube C. to admit the nutmeg or similar substance H, to be grated or rasped, the

page_text: outer shell or tube D. is then pressed or pushed on the inner shell or tube (, and as
the protuberance or rim on the outer tube D. presses by means of a slot a projection
on the outer surface of the inner tube C. at N. the outer tube D. is then turned round
and the apparatus is ready to grind or rasp the nutmeg or similar substance.
In the inner portion of the outer shell or cylinder Å. a grater or rasper G. is so
constructed as to be capable of being revolved or rotated by means of the spindle L,
and handle M. to which it is attached. The surface of the inner portion or grating
cylinder G. is so cut or perforated with narrow slits or cutting edges and can be so
made as to admit of being removed by taking off the screw K. for the purpose of
cleansing the apparatus or reversing the grater G, when the upper part of the surface
or cutting edge gets worn away.
Thus two nutmegs or similar substances can be grated or rasped at the same time
more effectually and economically than by the ordinary methods now in use.
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. The application of a perforated cylindrical grater or rasper with central rotatory
action for the purpose of grating or rasping nutmegs or similar substances, as
hereinbefore described.
2. That by the application of the central rotatory action to this apparatus two or
more nutmegs or similar substances can be grated or rasped at the same time, as
hereinbefore described.
3. That nutmegs or similar substances can with this apparatus be more economically
and advantageously grated or rasped than heretofore, as hereinbefore described.
Dated this 23rd day of December 1887.
