PROVISIONAL SPECIFICATION.
Improved Grater for Culinary Purposes.
I, JOHN DAVIDSON, of High Street, Wick in the County of Caithness,
Watchmaker and Jeweller, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is an Improved Grater for Culinary Purposes
generally of such a construction that one of the grating surfaces acts also as a
sieve through which the particles have to pass before escaping thus ensuring a
uniformity of size.
My improved grater is practically constructed of a metal cylindrical vessel open
at both ends and of any desirable height and diameter into the lower end of which
fits a short tube having its lower edge flanged to prevent it sliding too far into the
cylindrical vessel whilst over its upper end is stretched wire gauze either flat or
bent so that its upper side presents a concave surface. Across the upper surface
of said gauze is secured a metal bar or wire to prevent the grater proper coming
directly in contact with it and also to prevent the material to be grated revolving
with said grater.
Across the upper end of the cylindrical vessel are secured two stays in holes or
bearings in the centres of which a vertical spindle revolves and slides longitudinally.
The upper end of this spindle is provided with a suitably cranked handle whilst
secured to its lower end is a wooden disc loosely fitting the cylindrical vessel and
over the lower face of which fits the grater proper in the form of a metal plate,
with a flat or convex lower surface, punched in a similar manner to the ordinary
nutmeg grater which may be either tacked on or flanged to enable it to fit on to
said wooden disc.
The material to be grated is placed in the cylindrical vessel beneath the grater
proper through an opening having a sliding or other suitable door in the side of
the former, the spindle on which said grater is fixed being then forced downwards
and revolved.
The cylindrical vessel may be provided with a suitable handle by means of which
it may be held during the grating operation.

COMPLETE SPECIFICATION.
Improved Grater for Culinary Purposes.
I, JOHN DAVIDSON, of High Street, Wick, in the County of Caithness,
Scotland, Watchmaker, 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:-
The object of my invention is an Improved Grater for Culinary Purposes
generally of such a construction that one of the grating surfaces acts also as a
sieve through which the particles have to pass before escaping, thus ensuring a
uniformity of size.
My improved grater is practically constructed of a metal cylindrical vessel open
at both ends and of any desirable height and diameter into the lower end of which

page_text: fits a short tube having its lower edge flanged to prevent it sliding too far into the
cylindrical vessel whilst over its upper end is stretched wire gauze either flat or
bent so that its upper side presents a concave surface. Across the upper surface
of said gauze is secured a metal bar or wire to prevent the material to be grated
revolving with the grater proper and in the centre of this bar or wire a projection
is formed in or attached to prevent said grater coming in direct contact with the
gauze or bar.
Across the upper end of the cylindrical vessel are secured two stays, in holes or
bearings in the centres of which a vertical spindle revolves and slides longitudinally.
The upper end of this spindle is provided with a suitably cranked handle whilst
secured to its lower end is a disc of wood or other suitable material loosely fitting
the cylindrical vessel and over the lower face of which fits the grater proper in the
form of a metal plate, with a flat or convex lower surface punched in a similar
manner to the ordinary nutmeg grater and which may be either tacked on or
Hanged to enable it to fit on to said disc.
The material to be grated is placed in the cylindrical vessel beneath the grater
proper through an opening having a sliding or other suitable door in the side of
the former, the spindle on which said grater is fixed being then forced downwards
and revolved.
The cylindrical vessel may be provided with a suitable handle by means of
which it may be held during the grating operation.
And in order that my invention may be more fully understood and carried into
practice will now proceed to describe the same with reference to the accompanying
drawings of which Fig. 1 is a part sectional elevation, and Fig. 2 a plan, half
sectional on line -y Fig. 1 of a grater constructed according to my invention.
The cylindrical vessel a has fitting into its lower end a short tube flanged at
its lower end to prevent it sliding too far into the vessel a and having wire gauze <>
stretched across its upper end so that the upper side of said gauze presents a flat
or concave surface.
A metal bar or wire d is secured across the upper surface of this gauze to
prevent the material being grated revolving with the grater proper whilst a loop
or projection is formed in or attached to the middle of said wire to prevent the
grater coming directly in contact with the gauze or bar.
Across the upper end of the cylindrical vessel a are secured two stays e in holes
or bearings in the centres of which a vertical spindle revolves and slides
longitudinally.
The upper end of this spindle is provided with a suitable handle g whilst secured
to its lower end is a disc of wood or other suitable material loosely fitting the
vessel a and over the lower part of which fits the grater proper k in the form of a
metal plate with a flat or couvex lower surface, punched in a similar manner to
the ordinary nutmeg grater and which may be either tacked on or flanged to enable
it to fit on to said disc h.
An opening is formed in the side of the vessel a and provided with a sliding or
other suitable door m to enable the material to be grated to be placed between the
grater k, which may be raised for the purpose, and the gauze sieve e whilst at the
opposite side of the vessel a a suitable handle is provided.
"
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is.
A grater for culinary purposes constructed and arranged substantially as
described and illustrated in the accompanying drawings.
