s or willowing' or opening
Year: 1897

page_text: I, JOSEPH LIEBHOLD, of Quedlinburg, in the German Empire, Works Director,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in devils or willowing' or opening
machines.
It is of essential importance in such machines for shoddy that the material
which has not been completely opened or loosened be conveyed back to the
feeding point in order that it can be returned to the drum or cylinder and again
worked.
According to this invention I effect this in a novel manner by means of
travelling aprons or carriers as hereinafter described.
In carrying out the invention I arrange behind the rotating drum or cylinder
an adjustable partition and I also provide travelling aprons or carriers which
run over guide rollers.
The two endless carriers are so arranged relatively to one another that they
run together when moving upwards. At the upper part of the machine they
separate.
The operation is as follows,the rotating drum or cylinder partially opens or
loosens the material which is fed to it from the feed aprons and carries it with
it in its rotation. The loosened or opened material is conveyed between the parti-
tion and the drum downwards but the portions of the material which have not
been completely opened or loosened, are, in consequence of their centrifugal
force, projected over the top of the partition on to the first endless apron or
carrier which at this point runs in a horizontal direction.
This material is now conveyed by the said apron towards the second carrier
so that it is gripped between the two carriers and conveyed to the upper part of
the machine.
As soon as the material has arrived at the position where the two carriers
separate it lies free upon the second apron and proceeds forward to be delivered
to the uppermost feed apron by any suitable device.
The feed aprons feed the material in a known manner to the feed or nipping
rollers the upper of which are provided with trays or guides lying concentrically
to the drum and an automatic device arranged at the lower part of the machine
conveys the opened or loosened material directly to the press.
It will be obvious that my improvements are applicable to the machine
described in my former Patent No. 5014 of 1897.

page_text: Improvements in Devils or Willowing or Opening Machines.
I, JOSEPH LIEBHOLD, of Quedlinburg, in the German Empire, Works Director,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described in and by the following state-
ment;-
This invention relates to improvements in devils or opening machines.
It is of essential importance in such machines for treating shoddy that the
material which has not been completely opened or loosened be conveyed back
to the feeding point in order that it can be returned to the drum or cylinder
and again worked.
According to this invention I effect this in a novel manner by means of
travelling aprons or carriers as hereinafter described and as illustrated in the
accompanying drawing which is a view of the improved machine.
In carrying out the invention I arrange behind the rotating drum or cylinder
A an adjustable partition C and I also provide travelling aprons or carriers 1)¹,
D3 which run over guide rollers E', E. Es. The carrier D¹ passes around the
rollers E¹, E, E³, E4, E5, E6 and back to E. The carrier D³ passes around the
rollers Es to E3, E7, E8 and back to Ea.
As shown the two endless carriers D1, D2 are so arranged relatively to one
another that they run together when moving upwards from the roller E up to
the roller E3. At this point they separate the carrier D3 passing forwards and
downwards to the roller E' and the carrier D¹ passing over the roller E, back
over the roller E and thence to the rollers E and E.
The operation is as follows, the rotating drum or cylinder A partially opens
or loosens the material which is fed to it from the feed aprons B', 13 and carries
it with it in its rotation. The loosened or opened material is conveyed between
the partition C and the drum A downwards but the portions of the material
which have not been completely opened or loosened, are, in consequence of their
centrifugal force, projected over the top of the partition (on to the endless apron
or carrier which at this point runs in a horizontal direction.
This material is now conveyed by the said apron 11 towards the carrier_])ª
so that it is gripped between the two carriers and conveyed upwards until it
reaches the roller E where the two carriers D1, D2 separate and the material
lies free upon the carrier D2 and proceeds forward to the roller E7 to be delivered
to the uppermost feed apron B₁ by any suitable device.
The feed aprons B1, B2 feed the material in a known manner to the feed or
nipping rollers the upper of which are provided with trays or guides F¹, F*
lying concentrically to the drum, the said guides being of known construction
and designed to keep the material up to the drum; an automatic device such as
an endless apron running over a pulley G aranged at the lower part of the
machine conveys the opened or loosened material directly to the baling press.
It will be obvious that my improvements are applicable both to machines of
the kind described in my former Patent No. 5014 of 1897 as also to those having
only a single feed.
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. A devil or opening machine wherein the material which has not been
thoroughly opened is thrown upon a carrying device which returns it to the feed

page_text: apron so that it can be again passed through the machine, whilst the fully
opened material is delivered from the drum without being subjected to a second
treatment, substantially as herein before described.
2. The devil or opening machine herein before described and illustrated in the
accompanying drawing.
