COMPLETE SPECIFICATION.
Improved Apparatus for Mashing Potatoes.
I ARTHUR BROWN of Harpurhey, Manchester in the County of Lancaster Corn
Dealer 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 relates to improved apparatus to be used for mashing potatoes for
the use of bakers in the manufacture of bread.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1. is a vertical section and
Fig. 2 a plan view with the hopper removed, of my improved apparatus.
a is a trough or hopper supported on a suitable frame b. In the lower part of
this hopper I mount two rollers c and d.
The roller is mounted upon an axle e at one end of which is a winch bandle by
means of which it can be turned, and at the other end is a spur pinion g driving a
spur wheel h fixed on the axle i of the other roller d which it thus turns at a slower
speed.
The roller e is provided with pins or pegs and acts as a gatherer to draw or force
the potatoes down onto the roller d and also to partially mash them.
The latter is provided with rows of teeth or pegs which are made of a square,
i
lozenge shape or triangular section and so fixed that the angular edge is forwards.
These teeth or pegs are mounted in lines or rows which are slightly diagonal to
the axis (see Fig. 2) so that they follow each other, and each alternate line or row is
inclined in an opposite direction so that they have no tendency to force the potatoes
towards either side of the hopper.
The teeth or pegs l act between two rows of similar teeth or pegs m fixed in the
throat or opening at the bottom of the hopper a. The latter is mounted on a hinge
so that it can be thrown over into the position shown by dotted lines on Fig. 1.
when it is required to clean or wash out the machine.
The caps of the bearings o which carry the axle e of the roller c are also hinged
and fastened by a thumb-nut so that the roller c can easily be removed for the same
purpose.
The potatoes being steamed in their skins in the usual manner are placed in the
hopper a when by a few turns of the handle they will be delivered properly washed
into any suitable vessel placed beneath.
They are then sieved as usual to remove the pieces of skin and are ready for use.
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:-
1st. The general construction and arrangement of parts constituting and improved
potato masher for the use of bakers substantially as hereinbefore described and
illustrated by the drawing annexed.
2nd. The particular form and arrangement of the teeth or pegs 1 and m.
