and in Packing the same in Sacks.
We, Sir BERNHARD SAMUELSON Baronet, and ERNEST SAMUELSON both of
Banbury, Oxfordshire, Engineers, do hereby declare the nature of this invention to
be as follows:-
Our invention relates to the machinery employed in dressing flour or meal and in
putting it into sacks when finished-and it consists first as to Dressing & Purifying
Machines, in a mode of cleaning the surfaces of the Sieves of the said Machines, and
secondly as to Sack fillers or so called "Possers" in a mode of giving to these a
differential movement.
For the purpose of cleaning the said surfaces we use a brush as usual in such
machines and our invention consists in causing the brush to reciprocate by a device
placed at one end of the machine, which device is composed substantially of two bevil
wheels placed face to face, an "idle" wheel, and a double clutch between the said
bevil wheels gearing alternately into one or the other of them & so receiving motion
alternately in opposite directions the clutch slides on a feathered shaft and thus causes
this shaft also to revolve in opposite directions, the revolution of the shaft gives
motion to a fork which throws the double clutch backwards & forwards at the
proper times.
The same shaft carries a double winding drum for winding and unwinding a cord
or its equivalent to which cord the brush is attached and which cord as it is wound or
unwound causes the brush to move from end to end of the Sieve & vice versa.
The object of giving a differential motion to "Possers" is in order to pack the flour
or meal in the sack by the impact of the sack & flour therein, on the floor of the
mill-and at the same time to raise the sack without unnecessary stress, and our
invention consists in giving a rapid descending and a slow rising motion to the sack
by means of a lever oscillating on a fulcrum from one end of which lever the sack is
suspended, whilst the opposite end is moved up and down by an eccentric device so
proportioned as to give the desired alternate rapid and slow motions.

Improvements in Machinery Employed in Dressing Flour or Meal
and in Packing the same in Sacks.
We Sir BERNHARD SAMUELSON Baronet and ERNEST SAMUELSON both ol
Banbury Oxfordshire Engineers, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described ani
ascertained in and by the following statement:-
Our invention relates to machinery employed in packing flour or meal into sacks,
and it consists of an improved mode of giving to sack fillers or so called "
"
possers Al
differential movement.
The object of giving a differential motion to " possers" is in order to pack the
flour or meal in the sack by the impact of the sack, and flour therein, on the floor of
the mill, and at the same time to raise the sack without unnecessary stress, and our
invention consists in giving a rapid descending, and a slow rising motion to the sack
by means of a lever oscillating on a fulcrum, from one end of which lever the sack is
suspended whilst the opposite end is moved up and down by an eccentric device so
proportioned as to give the desired alternate rapid and slow motions.
In the accompanying drawings Fig. I is a side elevation of the sack filler or
posser Fig. II is a plan of same; the same letters refer to the same parts in both
Figs. I and II.
A is a lever oscillating upon the fulcrum shaft B which is carried by the bracket C;
this bracket being fastened to the underside of the joists X, X, of the mill, or other-
*wise suitably fixed. From one end of this lever the sack S is suspended in the usual
way by means of the chains.D D, the mouth of the sack being fastened to the ring R.
which slides up and down the tube T, the other end E of the lover A is connected by
means of a pin-P to one end of the link F, the other end of this link being connected
to the crank pin G which is fixed to the crank wheel H. The crank wheel H is
carried upon the shaft J, this shaft being supported from the joists by the hangers KK
or by other suitable means. The centre line of the crank shaft J being placed
eccentrically, between the fulcrum shaft B and the pin P at the end E of the lever A.
By this means, when the crank wheel is rotated the pin P and, with it, the end E of
lever A has a rapid rising motion and a slow falling one, thus the sack S is allowed
to drop suddenly upon the floor of the mill and so pack the flour or meal closely,
whereas the lifting motion is a slower one and not-so-sudden in its action.

page_text: Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed we declare that we do not claim the
separate parts of the device as described, but what we do claim is
The combination of parts to form an eccentric device for giving an alternate rapid
and slow motion to Possers as shown and described.
