Improvements in Machines for the Stripping or Shredding or
Breaking up of Feathers and other Fibrous Substances.
I, FRANK ANDREE, of 1761, Milwaukee Avenue, in the City of Chicago, State of
Illinois, United States of America, Manufacturer, do hereby declare the nature of
my invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to a novel construction in a feather stripping machine, the
object being to provide a machine of this character by means of which feathers or
other like light fibrous material can be easily and quickly cut into shreds, and consists
in the features of construction and combinations of parts hereinafter fully described
and claimed.
In the accompanying drawings illustrating my invention:
Figure 1 is a side elevation, partially in longitudinal section, of a machine
constructed in accordance with my invention.
Fig. 2 is a transverse section of the same on the line 2-2 of Fig. 1.
Referring now to said drawings, A indicates the bed or base of my stripping
machine upon which the cylindrical casing B is supported. Said casing B is
preferably made in two parts, the lower of which is secured upon said base A, and the
upper of which is hinged to said lower portion by means of the hinges 1. By turning
said upper portion on its hinges to the position shown in dotted lines in Fig. 2, the
working parts of the machine are obviously placed within easy reach for repair. Said
upper portion of said cylinder is held in place upon said lower portion by means of
suitable clamping devices, as shown.
Mounted upon said lower portion of said cylindrical casing at the ends of same,
are bearings 2 in which a shaft 3 is journalled which passes longitudinally through
the center of said cylindrical casing B. Rigidly mounted upon said shaft 3 within
said cylinder B are two disks 4 to the opposite sides of which radial L-shaped arms 5
are rigidly secured. Mounted upon the outermost portions of said L-shaped arms 5
are a plurality of parallel knives 6 which extend radially outwardly and end close to
the inner face of said casing B. Knives 7 are mounted upon the inner face of said
upper portion of said casing B and extend radially inwardly from same, being so
placed that each of said knives 6 will pass between two of said knives 7 and vice
versa. Beaters or fingers 8 are mounted upon the circumferences of said disks 4 and
are adapted to prevent the accumulation of material to be shredded in the spaces not
reached by the knives.
The material to be shredded is introduced into the cylinder through the trough or
passage 9 which communicates with said cylinder adjacent the center thereof, and
passes lengthwise through said cylinder. During its passage it is acted upon by said
knives which revolve at a very high speed so that by the time it has reached the
other or discharge end of said cylinder it is cut into fine shreds, and is discharged
through the discharge opening in said cylinder which communicates with the pipe 11
through which the shredded material is led to any desired receptacle. The said

page_text: discharge opening is made in the cylindrical wall of the cylinder so that the air
currents produced in said cylinder by the revolution of said knives and the parts to
which they are secured, will be discharged through said pipe 11 by centrifugal force
and carry the light shreds with them.
I have provided valves 12 and 13 to control the amount of material fed to and
discharged from said cylinder and thus by setting said valve 13 so as to reduce the
area of the discharge opening the material can be retained in said cylinder for any
desired length of time and thus reduced to any desired degree of fineness.
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 :-
--
1. In a stripping machine, the combination with a cylinder made in two parts
hinged together, of a shaft passing centrally through said cylinder and carrying
a plurality of disks rigidly mounted thereon, a plurality of L-shaped arms secured to
said disks and carrying a plurality of radially outwardly extending knives, a plurality
of radially inwardly extending knives mounted upon the inner face of said cylinder
and so located as to permit said outwardly extending knives to pass between the
the same, an inlet opening in one end of said cylinder adjacent its center, and
a discharge opening in the cylindrical wall of said cylinder adjacent its opposite
end.
2. In a stripping machine, the combination with a cylinder made in two parts
hinged together, of a shaft passing centrally through said cylinder and carrying
a plurality of disks rigidly mounted thereon, a plurality of L-shaped arms secured
to said disks and carrying a plurality of radially outwardly extending knives,
a plurality of beaters or fingers on the peripheries of said disks extending radially
outwardly therefrom, a plurality of radially inwardly extending knives secured to the
inner face of said cylinder and so located as to permit said outwardly extending
knives and beaters or fingers to pass between the same, a valve controlled inlet
opening in one end of said cylinder adjacent the center thereof, and a valve controlled
discharge opening in the cylindrical wall of said cylinder adjacent its opposite end,
substantially as described.
