Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both

Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
The device for automatically feeding machines for kneading or compressing
soap and the like plastic substances which forms the object of the present appli-
cation is a notable simplification of the arrangement described in patent
No. 1996095 which allows the crusher to be dispensed with and replaced by a single
feed roller, which modification has the further advantage of being applicable to
all existing machines of this kind as well as to new machines.
In the previous patent referred to it was explained that the machine was fed
by the crusher with a view to causing the material to fall in a disintegrated
condition between the spirals of the helix for the purpose of preventing it caking,
and doing away with hand labour for feeding it therein. For this object a corru-
gated knife or scraper removed the material in shavings from the last cylinder
of the crusher and it fell between the spirals of the helix which carried it below
the knife and towards the matrix.
Nevertheless it was unavoidable by reason of the shape and arrangement of the
said knife that the quantity of material discharged from the last cylinder corre-
sponded exactly to the quantity carried away by the matrix, as without this
condition the free space between the knife and the perimeter of the helix would
become filled with soap more or less caked and compressed, which would finally
form a spiral or helix of soap which would constantly fill the helix and prevent
it conveying the fresh material fed in so that the yield was limited to the
maximum quantity of movable soap that the helix could convey.
According to the present invention however this maximum yield is considerably
increased by an improved arrangement of feed whereby the quantity of soap
conveyed is compacted or compressed into the helix under the action of a knife."
The vacant space between the knife, the perimeter of the helix and the part
of the cylinder containing the helix is entirely avoided by reason of the circular
form of the knife which, instead of being fixed on a lateral extension of the wall
of the cylinder, is fixed on a flange running from the edge of the cut away wall
of the cylinder along the whole length of the knife, which latter thus continues
the wall of the cylinder in conformity with the perimeter of the helix up to a

page_text: point below the tangential line of the single feed roller which has the same
diameter as the. helix and the perimeter of which is tangential with the helix
by reason of its trunnions being mounted in brackets projecting from the cylinder
which is open above and surmounted by a hopper. Further the helix and the
roller have the same speed of rotation which is transmitted to them by suitable
driving gear in such a way as to cause them to revolve in opposite directions.
The working will be easily understood from the foregoing.
The material to be kneaded or condensed into a roll or extruded column is
conveyed promiscuously into the hopper and falls directly onto the helix which
tends to carry it towards the roller, which latter, revolving in an opposite direction,
compresses it and piles it between the spirals of the helix, the interstices of which
thus .convey the maximum of material which passes in front of the internal smooth
face of the curved knife, the full cutting edge of which latter scrapes off the
soap adhering to the roller in such a way that said roller always acts in a clean
or bare condition on the fresh material which is introduced into the hopper and
constantly drawn between the spirals of the helix by the co-operation of the helix
with the feed roller, which thus plays the part of the human hand formerly
necessary in this dangerous operation.
This simple arrangement for automatically feeding machines for kneading or
compressing soap and the like into a roll or extruded column is only possible for
such a sticky substance as soap on condition that the cylinder has no extrava-
sations for the reasons hereinbefore explained and therefore the cut away wall of
the cylinder opposite the roller must be itself sharpened as a scraper or sur-
mounted by a knife having the same shape as the cover.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
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:
The device for automatically feeding machines for kneading or compressing
soap and the like plastic substances which forms the object of the present appli-
cation is a notable simplification of the arrangement described in patent
No. 1996095 which allows the crusher to be dispensed with and replaced by a single
feed roller, which modification has the further advantage of being applicable to
all existing machines of this kind as well as to new machines.
In the previous patent referred to it was explained that the machine was fed
by the crusher with a view to causing the material to fall in a disintegrated

page_text: condition between the spirals of the helix for the purpose of preventing it caking,
and doing away with hand labour for feeding it therein. For this object a corru-
gated knife or scraper removed the material in shavings from the last cylinder
of the crusher and it fell between the spirals of the helix which carried it below
the knife and towards the matrix.
Nevertheless it was unavoidable by reason of the shape and arrangement of the
said knife that the quantity of material discharged from the last cylinder corre-
sponded exactly to the quantity carried away by the matrix, as without this
condition the free space between the knife and the perimeter of the helix would
become filled with soap more or less caked and compressed, which would finally
form a spiral or helix of soap which would constantly fill the helix and prevent
it conveying the fresh material fed in so that the yield was limited to the
maximum quantity of movable soap that the helix could convey.
According to the present invention however this maximum yield is considerably
increased by an improved arrangement of feed whereby the quantity of soap
conveyed is compacted or compressed into the helix under the action of a knife as
may be seen by reference to the accompanying drawings, in which,
Figure 1 is an end view partially in section; and
Figure 2, a longitudinal section of the kneader or compresser with automatio
feed.
The vacant space between the knife R, the perimeter of the helix S and the
part of the cylinder T containing the helix is entirely avoided by reason of the
circular form of the knife which, instead of being fixed on a lateral extension of
the wall of the cylinder, is fixed on a flange B running from the edge of the cut
away wall of the cylinder T along the whole length of the knife, which latter thus
continues the wall of the cylinder in conformity with the perimeter of the helix
up to a point below the tangential line of the single feed roller C, which has the
same diameter as the helix S and the perimeter of which is tangential with the
helix by reason of its trunnions being mounted in brackets K projecting from
above and surmounted by a hopper E. Further the
the cylinder T which is open the same speed of rotation which is transmitted to
helix S and the roller C
them by suitable driving gear H in such a way as to cause them to revolve in
opposite directions.
The working will be easily understood from the foregoing.
The material to be kneaded or condensed into a roll or extruded column is
conveyed promiscuously into the hopper E and falls directly onto the helix S
which tends to carry it towards the roller C, which latter, revolving in an opposite
direction, compresses it and piles it between the spirals of the helix, the inter-
stices of which thus convey the maximum of material which passes in front of the
internal smooth face of the curved knife R, the full cutting edge of which latter
scrapes off the soap adhering to the roller in such a way that said roller always
acts in a clean or bare condition on the fresh material which is introduced into
the hopper and constantly drawn between the spirals of the helix by the co-
operation of the helix with the feed roller, which thus plays the part of the human
hand formerly necessary in this dangerous operation.
This simple arrangement for automatically feeding machines for kneading or
compressing soap and the like into a roll or extruded column is only possible for
such a sticky substance as soap on condition that the cylinder has no extrava-
sations for the reasons hereinbefore explained and therefore the cut away wall of
the-cylinder opposite the roller must be itself sharpened as a scraper or sur-
mounted by a knife having the same shape as the cover.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is:-
com-
An arrangement for automatically feeding machines for kneading or
pressing soap and the like plastic substances having a propelling or conveying

page_text: helix and a tangential roller parallel to the helix, consisting of a feed roller,
arranged in such a way that the tangential line is situated immediately in front
of the edge, of the cut away wall of the helix-containing cylinder or of the cutting
edge of a knife or scraper of the same form as the cylindrical wall, with a view
to avoiding any extravasation of the cylinder below the roller, substantially as 5
hereinbefore described.,
