PROVISIONAL SPECIFICATION left by Thomas Wheeler at the Office of
the Commissioners of Patents, with his Petition, on the 14th July
1858.
I THOMAS WHEELER, of the Albion Iron Works, in the City of Oxford,
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED COMBINATION OP MACHINERY FOR CUTTING. SLICING. GRATING, AND
PULPING TURNIPS, MANGOLD WURZEL, AND OTHER ROOTS," to be as follows:-
This Invention relates to various improvements in the details and the
general construction and arrangement of turnip cutters and root graters,
pulpers, and slicers, and for the purpose of pulping fruit and bulbous roots,
and consist in casting suitable apertures or openings in a conical disc or
discs set at any angle, or in flat discs or cylinders; to these apertures suitably
shaped knives are fixed. The knives may be punched through the solid plates
and struck up with the first or second die or punch; the knives may be of a
gouge, diamond, or square shape, and flat knives may be applied to the flat
discs for slicing purposes. Any of the above mentioned knives may be
employed with any of the above mentioned discs or cylinders. A series
of knives or cutting points may be affixed to the concave portions or
inside of the disc or barrel, and these knives may be applied to Moody's or
Gardner's barrel. Cast or wrought iron knives may be employed working in
the concave portions of the discs, these knives may be cast in the disc or barrel
itself, or they may be rivetted or screwed or secured to it by any other convenient

page_text: fastening. 1 also propose to use a roller, consisting of a worm or thread fixed
upon a cone, and made at convenient angles, so as to work the conical dise; or
a grooved or plain roller may be used, either revolving or stationary, and worked
in the inside by a crank, eccentric or zig-zig vibrating motion, or by pro-
jecting points or knives; the disc cylinder or barrel may be fluted either on
the back or front, the flutes to be of a gouge shape, half round, or at any
suitable angle. Small knives, stationary or otherwise, may be used intersected
between knives working at the back of the conical disc. In some cases I
employ them with knives fixed to a small roller with or without a backward
and forward motion; or, I fasten the knives, either cast or wrought, into
a plain plate. All the above improvements may be applied to one solid cast,
wrought or steel plate or plates, and when these improvements are combined
in one machine, or in any parts of machines working together. a throw out
lever handle or screw may be employed for the purpose of connecting or
disconnecting any part of the motions, so that any portion of the machinery
may be separately worked. A grating working at the front or the back of
the disc may be employed for the purpose of cleaning the knives. Any
required number of knives may be used, either of a large or small size, and of
a flat, half round, or angular shape.
These machines may be connected to a shaft on the ordinary principle of
turnip cutters, or may be connected to an axis or spindle connected with the
running wheels of a cart or wagon, so as to cut food when travelling from
place to place.
