COMPLETE SPECIFICATION.
An Improved Machine for Mashing or Rubbing Through a Sieve
Potatoes, Fruit, and the like.
I, JOSEF BRAUN of Pfeddersheim near Worms in the Empire of Germany,
Preserve Manufacturer 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 for its object to entirely displace all the household appliances
used for mashing or rubbing or forcing through a sieve, potatoes, fruit and the like,
for the purpose of producing an even pure mash or extract, as such appliances
leave much to be desired as regards their execution.
The machine is so constructed that notwithstanding its great power of execution
and the accessibility of its movable parts, thereby ensuring great facility in
keeping clean, it may yet be made so cheaply that even the smallest householder
may procure one.
It consists of a shaft a on which two circular sheet metal discs and b' are seated
and firmly connected, between which discs three or more rollers c of wood, porcelain
or the like are movably arranged.
C
is
This roller mechanism, the discs and together with the various rollers
then tightly enclosed in a case which is provided above with a funnel e through
which are fed the substances which are to be pressed through the apparatus, and
heneath with an outlet for the mash or extract and at the side with a lid or
door for the insertion of the roller mechanism into the case. The part of the
cylindrical case & which stands over the outlet is separated therefrom by means
of a removable sieve which has meshes of suitable size, in such a way that
the surface of the sieve and the inner surface of the case d form an unbroken
cylindrical surface to which the roller system moves concentrically with little
room for play.
A light cast iron frame i serves to hold the case d and to support the shaft a by
means of the bearings or sockets h. This frame is provided below with a screw k
by means of which the whole apparatus may be clamped to a table top . The
mode of working is the simplest possible and consists in pouring the substance
through the funnel e whilst the roller mechanism is rotated by means of the crank m,
such substance being then pressed by the rollers against and through the sieve g
from whence it runs through the outlet into a glass placed beneath the same,
In order
whilst the extracted fibres and the like remain as residue in the case d.
to thoroughly and conveniently clean the machine after use it is absolutely necessary
to be able to take the machine apart easily and rapidly. This is done by releasing
the screw after which the crank handle m is removed from the shaft a and the
entire roller mechanism may be drawn to the right out of the case d after the
door o
has been opened, so that this case and the roller mechanism are thoroughly
accessible from all sides.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
An improved machine for mashing or rubbing through a sieve, potatoes, fruit
and the like consisting of several separate rollers revolving between end
plates fixed to a driving shaft a, the whole being enclosed in a suitable casing,
the lower portion of which is formed of a removable sieve g, whereby, on the

page_text: rotation of the driving shaft, the inserted substances are squeezed by means of the
separate rollers against the walls of the case and forced through the removable
sieve substantially as described and illustrated.
