PROVISIONAL SPECIFICATION left by the said Carl Pieper at the Office

"
A NEW METHOD OF DISINTEGRATING RAGS AND
OTHER FIBROUS MATERIAL, AND MACHINE TO BE USED THEREFOR," a communication
to me from Harry Friederichs and Christian Philippi, residing both at Hainholz
near Hanover, Kingdom of Prussia, German Empire,
This invention relates to the disintegration of rags and other fibrous material for
the purpose of obtaining therefrom a product (or stuff) adapted for the manufacture
of paper, card-board, &c., and it substantially consists in compressing the said
material into a compact mass or body, and thereupon subjecting the same to the
action of rapidly rotating serrated cutters.
By preference the material to be reduced is made up, within a suitable drum, in
the form of a cylinder secured upon a shaft, and fit to be rotated while its periphery
is acted upon by the cutters. The disintegrated fibres are drawn away from the
machine and delivered into a suitable receptacle by a current of air. By means of
appropriate arrangements combined with the conduit leading from the machine to
the said receptacle, the fibres may be separated according to their varying degree
of fineness.
The machine to be used in the process substantially consists of a rotating
cylinder carrying a series of serrated blades and of one or more shafts serving to
form thereon the cylindrical bodies of rags, &c., and provided each with two disks
for securing the latter between them. The bearings of these shafts are arranged to
be operated forward and backward by a scrow for the purpose of pressing the
cylinders of rags against the cutter-cylinders.

CARL PIEPER, Civil Engineer and Patent-Agent resident at 109-110 Gneisenau-
strasse Berlin S.W. Prussia. "A NEW METHOD OF DISINTEGRATING RAGS AND
-OTHER-FIBROUS-MATERIAL, AND_MACHINE_TO_BE_USED THEREFOR"-A communi-
cation to me from Harry Friederichs and Christian Philippi, residing both at
Hainholz near Hanover, Kingdom of Prussia, German empire.
This invention relates to the disintegration of rags and other fibrous material for
the purpose of obtaining therefrom a product (or stuff) adapted for the manufacture
of paper, card-board &c., and it substantially consists in compressing the said
material into a compact mass or body, forming a solid of revolution and thereupon
subjecting the same while being rotated, to the action of rapidly revolving serrated
cutters.
'
By preference the material to be reduced, is made up in the form of a cylinder.
For this purpose a shaft having a disc fixed thereon and adapted to carry another
disc opposite to the former, is placed centrally into a cylindrical drum. Rags,. old
cordage or other like materials are then put into the said drum round about the
shaft, the removable disc is placed on the same, and power is applied to compress
the material. Fiually the removable disc is secured to the shaft. The shaft with
the body of rags &c., upon it, is then taken out of the drum and placed into the
bearings provided therefor on the frame of the disintegrating machine. Motion
having been imparted to the cutters as well as to the body of rags, the latter is
slowly forced forward against the former (or vice-versa) by the medium of a screw
or otherwise, while a current of air created by a fan or other appliance draws the
disintegrated fibres away from the machine and delivers them into a suitable
receptacle. By means of appropriate arrangements combined with the conduit
leading from the machine to the said receptacle, the fibres may be separated
according to their different degree of fineness.
On the annexed two sheets of drawings a machine and a compressing apparatus
adapted for carrying out the described process, are represented. Fig 1 is a front
view of the disintegrating machine, Fig: 2 a plan thereof, and Fig: 3 an end
elevation taken from the right hand side of the machine as shown in Figs 1 and 2;
while Figs 4 and 5 represent a part in detail to a larger scale. Fig: 6 shows the
compressing apparatus in vertical section.
The machine consists in the first place of a cylinder a carrying on its periphery
a serios of serrated blades, by preference arranged in spiral lines. This cylinder,
to which the Figs 4 and 5 relate, is fixed on a shaft b, and it is rotated with
considerable speed by a strap passing over the pulley c. dd are two shafts cach
provided with a disc e which is or may be permanently fixed, and with a disc e',
so arranged that it can easily be detached; besides they carry each a driving
pulley. On these shafts and between the discs e and e¹ the cylindrical bodies of
rags are formed. The bearings of the shafts d d are placed on saddles f sliding
on the ways hand operated forward or backward as required by a screw g. The
machine is provided with two shafts d d in order that one may be removed to
receive a new supply of rags, while the other is furnished with material and in
operation. There may, however, be but one, or more than two of these shafts, if
preferred.
The compressing apparatus represented by Fig: 6 consists of the fixed drum k,
the one and in the hooks m and iointed at the lower

page_text: end to the screws n engaging with inside threads in the bossos of the pinions o,
which gear with the wheel p driven by a strap running over the pulley q. One
of the shafts & of the disintegrating machine having been placed, together with its
fixed disc e, into the drum, the latter is filled with rags, the disk e¹ is placed on
the material and the rods are turned up, so as to cause the books n to project
through the slits provided therefor in the drum, and to catch over the disc e¹.
The rags having thereupon been compressed to the required degree by the
operation of the machine, the disc e' is secured by the nut r, the rods are thrown
back and the shaft & with the cylinder of rags upon it, is drawn or pressed out of
the drum.
Instead of this apparatus, however, any other suitable press, whether working
by screws, knee-levers, hydraulic pressure or other appliances, may be made use
of. Moreover the drum in which the compression takes place, may be divided
lengthwise in two or more parts arranged to be secured together, in order to allow
the same to be easily detached from the rag cylinder.
Having thus described the nature and object of this invention and the manner
in which it is to be carried out in practice I hereby claim as new and essential
feature of the same:
1, The method of disintegrating rags and other fibrous materials by compressing
them into a compact mass forming a solid of revolution and thereupon subjecting
such mass, while being rotated, to the action of revolving cutters, substantially as
and for the purpose specified.
2, In the method of disintegrating rags and other fibrous materials substantially
as described, the process of compressing tho material over a shaft and within a
cylindrical drum, and securing the same between two disks on the said shaft, as
and for the purpose sot forth.
3 In a machine for disintegrating rags, the rotating cylinder a provided with
serrated cutters, in combination with one or more shafts d having the discs c
and e', and an adjusting mechanism by which the distance between the cylinder
and the shaft or shafts may be increased or decreased during the working,
substantially as and for the purpose described.
In Witness whereof I the said Carl Pieper have hereunto set my hand and
seal this twenty-sixth day of November in the year of our Lord one thousand
eight hundred and eighty-three.
