Improvements in Breaking, Opening and like Machines for Shoddy
and other Material.
I, ULRICH KOHLLÖFFEL, of Reutlingen, in the Empire of Germany, Manu-
facturer, 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 object of the present invention is a machine for breaking up shoddy or the
like wherein the delivery is not brought to the front under the feed table but in
the opposite direction towards the back. By this construction the arrangement
and the working of the machine are much more practical because the product is
not delivered to the front, that is to the same side where the feed is but can be
taken away behind the machine. In connection with this arrangement there is
used an apron which receives the product and delivers it uniformly as a fleece
thus permitting uninterrupted working of the machine. In the annexed drawing
two forms of such a machine are represented in longitudinal section. The drum a
provided with pins and working in connection with the cylinders z is partly
surrounded by a closed tray 6 beginning near the feed rollers z end extending
backwards to the escaping channel c tangentially arranged to the drum and
receiving the current of air originated by the drum and the dissociated material.
In the form shown in Fig. 1 the air escapes through the perforated drum dat
the rear end of the channel c whilst the material according to its weight flies
partly upon the endless lattice apron e; partly towards the circumference f of
the drum d. By the movement of the conveyer e and the drum d in the direction
of the feathered arrows the material escapes from the machine at g as a fleece.
The tray b surrounding the lower part of the drum a is used as a partition and
causes the whole current of air with the material to pass through the outlet
channel c. is the tambour by which the waste is thrown back on the spreading
table.
In the machine shown in Fig. II the drum d is suppressed and in its place the
endless conveyor or apron e is used for the passage of air and for this purpose it
is formed as a sieve or grating.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. A machine for breaking and opening shoddy or other material with an
upwardly working drum, having a closed tray 6 surrounding the lower part of
the drum a and an outlet channel c bearing on the back of the tray tangential to
the drum, for the purpose of carrying off the dissociated material by or at the
back of the machine.
2. A machine as-in Claim 1 having a delivery device composed of an endless

page_text: ribbon or lattice apron e for delivering the material in fleece form, the air outlet
being effected through a sieve drum d.
3. A machine as in Claim 1 having a delivery device composed of an endless
ribbon or lattice apron e provided with openings for the passage of air.
