Improvements in and relating to Graters or Instruments for Grating
or Cutting Up Vegetables and other substances.
I, DAVID WADDELL, of Russel Street, Wishaw, Lanarkshire, Tinsmith, do hereby
declare the nature of my invention to be as follows :-
--
This Invention has reference to improvements in and relating to graters for
grating or cutting up carrots, turnips, potatoes, bread, apples and other vegetables,
fruit, and substances, and which will give a better rubbing surface and be more
efficient and useful than graters as heretofore constructed.
According to my invention I form the grater of sheet tin, tinnel sheet steel, or
other metal, preferably of semi-circular or curved shape in cross section, and with a
handle at the near end, much of the general configuration of other culinary graters.
Along the longitudinal length of the grater I form according to my improvements at
short intervals apart, a series of transverse ridges made of small semi-circular or
conoidal horizontal hollow projections very close together and with open cutting ends
in the longitudinal direction at right angles to the transverse ridges, each row having
the projections in the line of the hollow of the preceding row, alternately and
successively. By a further improvement these transverse ridges may be made duplex
with semi-circular cutting edges both in the up and down longitudinal cutting
directions, and each double row be ranged alternately and successively in the hollows
of the cutting projections on either side of them. Although I have described the
cutting projections as being formed in line longitudinally and with the transverse
ridges at right angles thereto, this being preferred, yet in some cases when preferred
outting projections might be formed at an angle longitudinally, or with the transverse
ridges at an angle transversely. When the carrots, turnips, or other articles are
rubbed to-and-fro on the surface of these ridges or conoidal openings, they are cut
up and fall through the openings and are received on a table or vessel below the
grater, ready for culinary or other use, more in the form of narrow strings than
particles as has heretofore been the case with the vertical conoidal orifices and
projecting orifices of graters as heretofore constructed.
These improved graters may be, (although described as preferably formed of semi-
circular shape) made of a hollow drum or other desired shape in transverse section
and have the cutting teeth set to cut circumferentially and be operated by hand, or
they may receive a rotary motion through wheel or wheel friction gearing driven by
a band crank, or by a band and pulley from any prime moving shaft. The grated
strings in this arrangement might fall out through the lower end of the hollow ilrum,
preferably inclined at an angle for this purpose.

COMPLETE SPECIFICATION.
Improvements in and relating to Graters or Instruments for Grating
or Outting Up Vegetables and other substances.
1, DAVID WADDELL of Russell Street, Wishaw, Lanarkshire, Scotland, Tinsmith,
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:-
This Invention has reference to Improvements in and relating to Graters for
grating or cutting carrots, turnips, potatoes, bread, apples, cheese and other substances,

page_text: ind which will give a better rubbing surface and be more efficient and useful than
graters as heretofore constructed.
According to my Invention, 1 form the grater of sheet tinplate or other sheet
metal, preferably of semicircular or curved shape in cross section and with a handle
at the near end, much of the general configuration of other culinary graters. Along
the longitudinal length of the grater I form, according to my Improvements, at short
intervals apart, a series of transverse ridges, made of small semicircular or conoidal
horizontal hollow projections very close together and with open cutting ends in the
longitudinal direction at right angles to the transverse ridges, each row having
the projections in the line of the hollow of the preceding row alternately and
successively.
Although have described the cutting projections as being formed in line
longitudinally and with the transverse ridges at right angles thereto, this being
preferred yet in some cases, when preferred, cutting projections might be
formed at an angle longitudinally or with the transverse ridges at an angle
transversely.
When the carrots, turnips or other articles are rubbed to and fro on the surface of
those ridges or conoidal or otherwisu shaped openings they are received on a table
or vessel below the grater ready for culinary or other use, more in the form of
narrow strings than particles as has heretofore been the case with the vortical
conoidal orifices and projecting orifices of graters as heretofore constructed.
These improved graters may be, although described as preferably formed of
semicircular or curved shape, mide in the form of a hollow truncated cone or other
desired simpe, laving the cutting teeth set to cut circumferentially and he
operated by hand, or they may receive a rotary motion through wheel or wheol
friction gearing, driven by a hand crank or by a band and pulley from any prime
moving shaft. In this case the strings would fall out through the lower end of the
drum preferably inclined at an angle for this purpose.
In order that my Invention may be properly understood and readily carried into
effect, I will now proceed to describe the drawings hereunto annexed.
Figures 1, 2 and 3 are respectively a front elevation, a side elevation in section
and a plan partly in cross section of the hand grater made according to my present
Invention.
Figure 4 is a front elevation of a machine grater constructed according to my
present Invention.
In figures 1, 2 and 3, A and B respectively represent the body of grater and
handle attached thereto. From the body A are raised or formed rows of ridges () ()
and DD being hollow conoidal projections as shown at C and D in figures 1 and 2
and living, as shown more particularly at (and D in ligure 3, semicircular cutting
orifices. Thus, when the substance to be grated or cut up is rubbed downwards
over the surface of the grater, the said substance falls through in the form of narrow
(hreads or strings.
In figure 4, is a hollow truncated cone made of sheet metal, having rows of
hollow projections OO and PP raised or formed from it, which hollow projections
bave cutting orifices as shown at 0) and P. The said part 1 is mounted in a
benring on the cast iron or other metal stand M and driven by a hand crank N
according to the well known manner. When the said part. L is caused to rotate
by means of the crank handlo N, the projections of the rows 00 follow circum-
ferentially in the line of the hollows of the rows PP, cutting the carrot or other
substaned which rests on the lodge or shelf S into marrow strings which fall out
at the lower end of the drum L." The stand M is fastoned to a table or shelf by
means of the pinching screw R.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
The Improvements in graturs for cutting vegetables, fruits, consolidated fats,

page_text: cheese and other substances into narrow strings instead of particles as heretofore, by
means of rows of projecting orifices C, D, O and P, stamped, raised or formed from
sheets of metal in forms similar to A and L, each alternate row of projecting
orifices having its projections in the line of the hollows of the preceding and
succeeding rows, to be operated by band or power, thereof all substantially as and
operating in the manner herein before set forth with reference to the annexed
drawings.
