PROVISIONAL SPECIFICATION.
Improvements in the Process of and Apparatus for Producing Peat
Briquettes and the like.
I EMANUEL STAUBER, Engineer, of Bellevue Strasse 19, Berlin, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:-
In the process for producing peat briquettes according to this invention, the peat
from the bog is dried in the air or artificially and the fibre is then extracted and
the remaining mass is passed to the peat-press in order to be formed into briquettes.
As the fibrous material which is removed possesses little heating power and is of
small specific gravity the non fibrous peat briquettes are heavier and have a greater
heating value than ordinary peat briquettes of the same size. The non fibrous
peat can be more firmly compressed; such peat briquettes do not fall to pieces
when being burned and give less ash. A special advantage also is that the peat
fibre obtained can be profitably used for many other purposes as for example in the
production of roping and the like.
The machine for producing the non fibrous peat briquettes consists essentially of
a briquette press, the feed hopper of which is provided with an arrangement for
removing the fibre from the mass of peat; of a machine for producing peat
briquettes provided with an arrangement for extracting and removing the fibres
consisting of rotating tearing claws arranged between the feed hopper and the
opening into the actual press and of a shaking apparatus underneath provided with
fibre catchers; and of the arrangement of a press cylinder with a cover plate
movable backwards and with interchangeable mouthpieces for the purpose of
obtaining briquettes of different thicknesses.

Improvements in the Process of and Apparatus for Producing Peat
Briquettes and the like.
EMANUEL STAUBER, Engineer of Bellevue Strasse 19, Berlin, in the
Empire of Germany, 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 :-
In the process for producing peat briquettes according to this invention, the peat
from the bog is dried in the air or artificially and the fibre is then extracted as
long as possible and the remaining peat is passed to the peat-press in order to be
formed into briquettes. As the fibrous material which is removed possesses little
heating power and is of small specific gravity the non fibrous peat briquettes are
heavier and have a greater beating value than ordinary peat briquettes of the same
size. The non fibrous peat can be more firmly compressed; such peat briquettes
do not fall to pieces when being burned and give less ash. A special advantage
also is that the peat fibre obtained can be profitably used for many other purposes
as for example in the production of roping and the like.

page_text: The machine for producing the non fibrous peat briquettes consists essentially of
a briquette press, provided with an arrangement for extracting and removing the
fibres consisting of a rotating tearing or ginning apparatus and of a sieving
apparatus underneath provided with fibre catchers, arranged between the feed
hopper and the opening into the press.
The accompanying drawing shows in longitudinal section a machine constructed
according to this invention for producing non fibrous peat briquettes.
The air dried peat is put at once into the hopper a and passes thence to a
ginning apparatus fixed at the lower part to loosen the peat which falls on a shaking
sieve fixed underneath to separate the fibres from the peat. The ginning apparatus
consists essentially of two or more oppositely rotating rollers bb between which the
peat mass must pass in the direction of the arrows c to loosen the fibres from the peat
without breaking the fibres. The motion is imparted from outside the case d
surrounding the apparatus by means of toothed wheels and a chain d from the spur
gearing of the press. The sieving apparatus is fixed underneath within a case e
and consists essentially of a sieve fand a drawing in or fibre catcher apparatus g and
a driving gear h. The drawing in apparatus and fibre catcher is made of separate
wire rods in the shape of an inclined grid, the lower end of which projects through
an outlet opening into the case e. The driving gear h consists of a small shaft
provided with one or more eccentric projections i and operated by means of a chain
outside the case e from the gearing of the press so that the sieve and the fibre
catcher 9 are forced to one side intermittently, the return motion being effected
automatically by means of the weight of the parts which are hung on chains. The
long peat fibres remain on the grid g and in consequence of its shaking movement
slide downwards over its inclined surface finally falling out of the case e. The loose
peat freed from fibre, falls through the grid 9 on to the shaking sieve f, is here
broken up and in such condition finally reaches the briquette press.
The
In the briquette press a piston reciprocating in the cylinder n alternately closes
and opens the feed opening m so that fresh peat falls into the cylinder at each back-
ward movement of the pistou and is compressed by the forward movement.
peat is forced through a gradually diminishing entrance chamber o the outlet of
which corresponds to the size of the greatest thickness of briquette. To this can be
attached a second piece p from which the peat briquettes are finally deposited on a
table or the like. A special cutting apparatus is not necessary. Each fresh inlet
of peat through m forms a separate briquette which at the outlet is only slightly
attached to the preceeding one.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. The process for producing peat briquettes consisting essentially in removing
the fibre from the peat before it is pressed into briquettes substantially as
described.
2. The process for separating the fibre from peat moss consisting in ginning
or breaking up the peat and in sieving the broken up peat substantially as
described.
3. In sieving apparatus for separating the fibre from peat moss, providing the
sieve with a fibre catcher, substantially as described.
4. In a briquette press, a ginuing or breaking up apparatus and a sieving and
fibre catching apparatus situated between the feed hopper and the inlet to the
compressing cylinder for freeing the peat from the fibres substantially as described.
Dated this 9th day of February 1895.
