Briquettes" or Blocks of Compressed
Fuel.
I, ROBERT AUTON, of Birtloy, in the County of Durham, Engineer, do hereby declare
the nature of this invention to be as follows:-
The object of this invention is to press the briquettes or blocks in such a manner
that whilst they are equally well adapted for storing or packing for transit, they can
be readily broken into pieces suitable for use in boiler furnaces or in house fires and
thus to obviate the difficulty and waste which is found to exist in breaking ordinary
briquettes, requiring great force and resulting in irregular sizes and shapes with much
small.
"
To effect this the moulds in which they are pressed and the faces of the plunger "dies
are formed with projecting ribs, preferably of V shape, on the sides of the mould and the
ends of the plunger dies, which indent the briquette or block when being pressed with
longitudinal or transverse grooves, or both longitudinal and transverse grooves, of
V shape to such a depth that they can be easily broken through these grooves when
required for uso, into small square blocks.
Although grooves running longitudinally and transversely are preferable it is
obvious that diagonal grooves may be formed in two sides of the mould with transverse
grooves on the other two sides-and with or without grooves in the two ends-the
briquettes or blocks when broken forming triangular pieces.

Improvements in Making "Briquettes or Blocks of Compressed
Fuel.
I, ROBERT AUTON, of Birtley, in the County of Durham Engineer, do hereby
declare the nature of said 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 this invention is to press the "briquettes" or blocks in such a manner
that, whilst they are equally well adapted for storing or packing for transit, they
can be readily broken into pieces suitable for use in boiler furnaces or in house fires
and thus to obviate the difficulty and waste which is found to exist in breaking ordinary
"briquettes" requiring great force and resulting in irregular sizes and shapes with
much small.
To effect this the moulds in which they are pressed and the faces of the plunger
"dies" or either of them are formed with projecting ribs preferably of V shape,
on the sides of the mould and the faces of the plunger dies which indent the
briquette" or block when being pressed with longitudinal or transverse grooves, or
both longitudinal and transverse grooves, of V shape to such a depth that they can be
easily broken through these grooves when required for use into small blocks. Although
grooves running longitudinally and transversely aro preferable it is obvious that
diagonal grooves may be formed in front and back faces of the "briquette
or block
with straight corresponding grooves on the other two sides and with or without
grooves in the two ends-the "briquettes" or blocks when broken forming triangular
pieces.
DESCRIPTION OF DRAWINGS.
23
The accompanying 2 sheets of Drawings illustrate my invention adapted to mould
"briquettes "or blocks 12 ins. x 7 ins. x 5 ins. thick, when compressed, having grooves
at right angles in the front face next die plate in the two sides and in the ends but
grooves may also be formed in the back face if required and convenient to the working
of the moulds in the press. The figures on Sheet 1 are of half the actual size and
those on sheet 2 of the full size.
Fig. 1. sheet 1 is a plan of the mould and Fig. 2 a section on line ✗-X of fig. 1.
A is the mould preferably made of brass, fixed in the mould plate B which forms part
of the machine or apparatus.
CCC are the projecting ✓ shaped ribs which form corresponding grooves in the.
sides and ends of the pressed "briquette

CCC are the V shaped ribs projecting from the face
corresponding grooves in the front and back faces of the
DDD are V shaped recesses to allow the die plate to pass
projecting ribs CCC in the sides and ends of the mould.

page_text: The mould and die, or either of them, used in connection with this invention may be
perforated with holes as described in Specification of my application No. 3917 dated
March 13. 1888 when the fuel requires such treatment.
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 :-
"
In making briquettes or blocks of compressed fuel the use of moulds and die
plates, or either of them, having projections which form corresponding depressions in
the faces, sides and ends, or any of them, of the moulded "briquette
substantially as described and shewn, and with the objects set forth.
