PROVISIONAL SPECIFICATION.
Improvements relating to the Manufacture of Fuel Blocks.
I, CARL MAX SCHNAUDER, of 5 Wissmannstrasse, Berlin, in the Empire of
Germany, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manufacture of a binding agent for fuel blocks,
which agent is designed to be used for blocks consisting either of pit coal or
brown coal.
By the use of the binding agent produced according to my said invention the
manufacture of fuel blocks is considerably cheapened and the heating power of the
same improved.
It has heretofore been customary to use pitch or resin in the pure state as a
binding material in the manufacture of fuel blocks, thereby rendering the manu-
facture of such blocks very expensive, as these substances have always to be added
in such quantities that the particles of coal to be made into blocks will be coated
therewith and will adhere to each other when pressure is exerted upon them.
I have succeeded in producing a binding material at a lower rate by adding to
the pitch or resin very finely ground or pulverulent coal.
In carrying my invention into effect it is expedient to proceed in the following
manner;-1 part resin or pitch is mixed with from 2 to 4 times its quantity of
finely ground or pulverulent coal, preferably in a rotary drum to which heat is
applied. By this means the fine particles of coal are penetrated and surrounded
by the resin or pitch material so that they will form with the same a perfectly
homogeneous paste.
This paste is added in small quantities to the pit coal or brown coal to be pressed,
whereupon the compression takes place.
Such a resinous or pitchy binding material mixed with a suitable quantity of
pulverulent coal has as much binding power as an equal quantity of pure resin
or pitch, and it is therefore evident that by the application of such a binding
agent the fuel blocks can be manufactured at a very much lower rate than
heretofore.

I, CARL MAX SCHNAUDER, of 5 Wissmannstrasse Berlin, in the Empire of
Germany, Merchant, 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:-
My invention relates to the manufacture of a binding agent for fuel blocks,

page_text: which agent is designed to be used for blocks consisting of either pit coal or
brown coal.
By the use of the binding agent produced according to my said invention the
manufacture of fuel blocks is considerably cheapened and the heating power of the
same improved.
It has heretofore been customary to use pitch or resin in the pure state as a
binding material in the manufacture of fuel blocks, thereby rendering the manu-
facture of such blocks very expensive, as these substances bave always to be added
in such quantities that the particles of coal to be made into blocks will be coated
therewith and will adhere to each other when pressure is exerted upon them.
I have succeeded in producing a binding material at a lower rate by adding to
the pitch or resin very finely ground or pulverulent coal.

the fuel blocks can be manufactured at a very much lower rate than heretofore.
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 manufacture of a binding material for fuel blocks by mixing resin or
pitch while applying heat with a quantity of pulverulent coal, coke, or other
appropriate material, such binding agent being added to the material to be made
into blocks substantially as herein before described.
(2.) The manufacture of a binding material for fuel blocks substantially as and
for the purpose hereinbefore described.
