We FRANCIS DAKIN, Furnival Road, Caterer, and EDWARD BLANCHARD, Edgar
Street, Tinsmith, both of Sheffield in the County of York, do hereby declare the
nature of our said invention for AN IMPROVED MACHINE FOR MASHING POTATOES,
AND OTHER SIMILAR VEGETABLE ROOTS, AND FOR MIXING MATERIALS USED IN
COOKERY to be as follows:-
Our invention relates to improvements in machinery or apparatus for mashing
or crushing potatoes, and other similar cooked roots or vegetables, the object being
to accomplish the same rapidly and effectually, and without material loss of heat
by the vegetables under operation.
Our apparatus consists of a cylindrical casing or body, supported upon legs or
other suitable framework, and provided with a lid.
Through the longitudinal centre of the body a revolving shaft or axle is
supported in half bearings in each end plate, the top half of the bearings being
carried by the lid, so that when the said lid is raised the shaft or axle may be
lifted out for cleaning or other purposes.
The part of the axle or shaft that is enclosed in the body of the apparatus is
provided with rows of projecting rods or mashing prongs, extending towards the
internal periphery of the body and the lid; there are also two or more helical rods
attached to the shaft or axle extending the whole length or thereabouts of the
cylindrical body for the purpose of distributing the material as it is being acted
upon by the mashing or mixing prongs.
.
We prefer to fix a pinion upon the shaft on the outside of the body or casing,
gearing into a larger wheel which revolves in bearings fixed to the side of the
body, and which is actuated by a handle or equivalent means; this enables the
shaft or axle with its prongs to be rotated at a suitable speed.
The boiled potatoes are placed in the body or casing, the lid closed and secured
by a clasp, and a few turns of the handle reduces the potatoes to a soft mass or
pulp.

Vegetable Roots, and for Mixing Materials Used in Cookery.
We FRANCIS DAKIN, Furnival Road, Caterer, and EDWARD BLANCHARD, Edgar
Street, Tinsmith both of Sheffield in the County of York, do hereby declare the
nature of our invention for AN IMPROVED MACHINE FOR MASHING POTATOES, AND
OTHER SIMILAR VEGETABLE ROOTS, AND FOR MIXING MATERIALS USED IN COOKERY,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our invention relates to improvements in machinery or apparatus used for
mashing or crushing potatoes and other similar cooked roots or vegetables, or for
curd crushing, churning and like operations, the object being to accomplish the
same rapidly and effectually; and in the case of hot vegetables, to retain the heat
which is a great desideratum.
In order that our invention may be perfectly understood, we annex a sheet of
explanatory drawings of an apparatus suitable for mashing potatoes.
Fig. 1-is a side elevation of the machine closed--the handle being omitted.
Fig. 2 is the end elevation of same.
Fig. 3-plan of machine, with lid removed to show the revolving shaft and
prongs.
The apparatus consists of a cylindrical casting or body A, supported upon legs
or other suitable framework, and provided with a lid B preferably hinged at C,
and secured when closed by clasps D.
Through the longitudinal centre of the body or casing, a revolving shaft or
axle E, is carried by half bearings made in each end plate, the top half of the
bearings being carried by the end plates of the lid B, so that when the said lid is
raised, the shaft E, can be lifted out of its bearings, and the interior of the body
or casing cleaned out.
The part of the shaft E, that is enclosed in the body of the machine is provided
with a number of mashing prongs F, or projecting rods radiating from the shaft
and preferably consisting of four rows as shown in the drawing, extending towards
the internal periphery of the casing and lid.
Two (or more) helical rods G, are secured at both ends to the shaft, and are for
the purpose of distributing the material as it is being acted upon by the mashing
prongs F.
When the machine is to be driven by hand we fix upon the projecting end of
the shaft outside the casing, a small wheel or pinion H, gearing into a larger
wheel I, which is suitably held in bearings fixed to the side of the body or casing,
and which is turned by a handle or equivalent means fixed on its axle K;
arrangement enables the axle or shaft E, to be rotated at a suitable speed.

The boiled potatoes are placed in the body or casing, and the lid closed and
secured by the clasps, the handle is then turned round a few times, which reduces
the potatoes to a soft pulpy mass.
For mixing liquids or semiliquids, and similar purposes, we sometimes fix one or
more strips of suitable material across the prongs F, as shown by the dotted lines

page_text: in Fig. 3 which act as dashers when revolving through the liquid. The lid may
be provided with a ventilator, and heat may be applied to the casing by any
suitable means when desirable.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed or carried into practice, we
declare that what we claim is :-
1-A machine for mashing potatoes and other like vegetable roots, and for
mixing materials and similar purposes, substantially as hereinbefore described and
illustrated.
2-A machine for mashing potatoes and other like operations, consisting of a
casing (such as A. B.) containing a revolving shaft with prongs, (such as E) having
helical distributors (such as G)-driven in any suitable manner-and substantially
as herein before described and illustrated.
