I CASAR WOLFF, of Frankfort-on-the-Main, in the Empire of Germany, Mann-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to quill-stripping machines, and has for its object to enable
wing and tail quills, which have heretofore only been used for manuring purposes, to
he stripped by mechanical means in such a manner that they can be utilized in the
production of bolstering or cushioning material, bed feathers and the like.
The machine designed to achieve this result is characterized by the fact that the
completely stripped material is automatically conveyed through it to the outside,
whereas the parts which have not been sufficiently reduced during the first passage
through the machine are automatically caused to return again and again if required,
until they have been sufficiently stripped when they are ejected from the machine.
The said machine comprises an endless apron or transporter, moving in the interior
of a channel, at the rear end of which is arranged in a casing a stripping drum. The
latter, operating in conjunction with the cover of the said casing, effects the stripping
of the quills and at the same time acts as a fan whereby the stripped material is blown
over the transporter in the channel in such a manner that the completely stripped and
therefore lightest parts fly to the outside, whilst the fragments of quills not yet reduced
to the necessary fineness, by reason of their greater weight, fall back upon the aforesaid
transporter and are again and again conducted to the stripping drum until they have
attained the necessary degree of fineness.
In this manner the machine operates continuously, and automatically sorts the
material which has been subjected to the stripping operation.
In carrying my invention into practice the quills to be stripped are fed through
a lateral admission opening to the transporter which moves in the channel, either
by hand or automatically by a conveyer and are caused to pass by means of the.
said transporter to the stripping drum. This drum and the cover of its casing are
provided with points which perform the stripping action.
The stripping drum rotates in its closed casing at such a velocity that it acts as a
fan, causing a current of air which drives the stripped material on leaving the drum
over the transporter in the channel casing, and thereby effects the sorting.

page_text: The completely stripped parts fly into a receptacle placed outside the machine,
whilst the parts requiring further treatment fall back upon the transporter and are, if
necessary, again and again conducted to the stripping drum.
The separation of the completely stripped parts and the introduction of the fresh
quills is performed continuously.
The suction wind is taken by the drum through an opening in the channel casing
which opening is separated from the part of the channel for the current of air by means
of a horizontal partition.
The length of the channel and transporter varies according to the fineness of the
feathers to be obtained.

page_text: I, CASAR WOLFF, of Frankfort of Main, in the Empire of Germany, 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 relates to quill-stripping machines, and has for its object to enable
wing and tail quills, which have heretofore only been used for manuring purposes, to
be stripped by mechanical means in such a manner that they can be utilized in
the production of bolstering or cushioning material, bed feathers and the like.
The machine designed to achieve this result is characterized by the fact that the
completely stripped material is automatically conveyed through it to the outside,
whereas the parts which have not been sufficiently reduced during the first passage
through the machine are automatically caused to return again and again if required,
until they have been sufficiently stripped, and have been ejected from the machine.
The said machine comprises an endless apron or transporter moving in the interior
of a channel, at the rear end of which is arranged in a casing a stripping drum. The
latter operating in conjunction with the cover of the said casing effects the stripping
of the quills and at the same time acts as a fan, whereby the stripped material is
blown over the transporter in the channel in such a manner that the completely
stripped and therefore lightest parts fly to the outside, whilst the fragments of quills
not yet reduced to the necessary fineness, by reason of their greater weight, fall back
upon the aforesaid transporter and are again and again conducted to the stripping
drum until they have attained the necessary degree of fineness.
In this manner the machine operates continuously, and automatically sorts the
material which has been subjected to the stripping operation.
The accompanying drawing represents the machine in longitudinal and cross
section.
In carrying my invention into practice the quills to be stripped are fed through a
lateral admission opening F to the transporter D which moves in the channel B in the
direction of the arrows either by hand or automatically by a conveyor and are caused
to pass by means of the said transporter to the stripping drum A. This drum, and the
b, of its casing, bent to correspond therewith, are provided with points which
perform the stripping action.
cover a,
The stripping drum A rotates in its closed casing in the direction of the arrow 1 at
such a velocity that it acts as a fan, causing a current of air which chases the stripped
material on leaving the drum at a in the direction of the arrows 4 through the channel
casing B, over the transporter D, and thereby effects the sorting.
The completely stripped parts fly into a receptacle placed outside the machine,
whilst the parts requiring further treatment fall back upon the transporter and are if
necessary again and again conducted to the stripping drum. The separation of the
completely stripped parts and the introduction of the fresh quills are performed
continuously.

page_text: The suction wind is taken by the drum in the direction of the arrow from
the opening G in the channel casing, which opening is separated from the part of
the channel for the current of air by means of a horizontal partition E.
The length of the channel B and transporter D, varies according to the fiueness of
the feathers to be obtained.
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
A machine for stripping quills, in which the quills to be stripped are conducted by
a transporter D to a stripping drum A with a toothed cover B, and are there stripped,
the wind produced by the rotation of the drum causing the sufficiently stripped parts
to pass over the transporter to the outside, whereas the parts not yet worked by reason
of their greater gravity fall back upon the transporter and are again conducted to the
drum together with the fresh material introduced through F as above described.
