Improvements in the Manufacture of Briquettes and Patent Fuel,
and in Means and Apparatus Employed therefor.
1, HERBERT JOHN REID of 32 Sackville Street, West in the County of
London Gentleman do hereby declare the nature of this invention to be as
follows:-
-
My invention relates to the manufacture of briquettes made from coal dust, or
any suitable mixture, and for this purpose I employ a machine of the following
description.
Any suitable number of moulds, or blocks containing moulds, are provided, such
moulds, preferably, being of cylindrical shape. These same are connected together
so as to form an endless band which being rotated brings the moulds successively
into position between a set of rams in order that the coal dust or other mixture may
be pressed by them into briquettes of the required shape and consistency.
endless band thus formed passes over drums and is provided with guides arranged
in a framework, in any suitable way.
The
To fasten the blocks, forming the endless band, together I provide hinges or lugs
and pins which connect to the alternate ends of the said blocks or moulds.
The rams for compressing the briquettes are so arranged that one ram or set of
rams enters the moulds from the top and a second ram or set of rams enters from
the under side of the moulds, the rams moving towards the centre of the moulds and
giving an equal pressure to the top and bottom of the briquette.
The ends of these rams may be of a hollow or concave form so as to shape the
briquette with rounded ends, or otherwise.
To feed the moulds with the material or mixture to be pressed I provide any
suitable arrangement, such as a pugmill or mechanical stoker, placed in such
position that as the material in one set of moulds is being pressed the other
set immediately preceeding the same is being filled by such feeding arrangement.
On the opposite side of the rams, or succeeding the same, I provide an ejector by
which means the briquettes are pushed out of the moulds through the under side of
the same, when they are carried away by an endless band, or shoot, or other suitable
arrangement to any desired place.
The ejector is of similar construction to the rams and passes entirely through the
moulds from the top side in order to ensure the briquettes leaving the moulds in
every case and cleansing the same of any waste particles.
This arrangement thus provides for the feeding of one set of moulds while the
succeeding set of moulds is being operated upon by the rams and the again succeeding
one by the ejector.
I also provide an arrangement to travel the moulds so that they come successively
into position to be operated upon by the several arrangements described.
To provide for the working of the rams I arrange an upright frame connected
with the bed upon which the endless band, formed by the blocks, or moulds, travels
and in this frame I provide a centre upon which I place a rocking lever, such lever
also having two centres or pivots arranged one above and one beneath the main
centre and in line with the same.
To these centres or pivots are attached, by means of connecting links and suitable
pivots, the top and bottom rams beforementioned.

page_text: The bottom ram is connected by the beforementioned means to the top centre or
pivot and the top ram to the bottom centre or pivot.
The action of such arrangement is that when the end of the rocking lever is
raised, the top centre or pivot by describing an arc around the central pivot on
which the lever rocks is lowered thus bringing the bottom ram down and clear of
the moulds, and exactly the same motion occurs, but in an opposite direction, with
the top rams.
On the rocking lever being brought downwards to its horizontal position the top
and bottom rams are forced into the moulds and the centres are in a vertical line
with one another and the rams, thus providing for the least strain on the several
parts at the time of the greatest pressure in the moulds.
The rams are provided with guides which are attached to, or form part of the
vertical framework in order to ensure their entering the moulds centrally at all
times.
To provide for the motion of the ejector I arrange guides also attached to or
forming part of the vertical framework in which the ejector rams slide, and I attach
the ejector to the beforementioned rocking lever by means of a connecting link
which is pivotted to the rocking lever, the position of such pivot on the lever being
determined by the amount of travel required on the ejector rams.
To provide for the movement of the rocking lever I arrange a crank or crank-
wheel and connect the same to the beforementioned lever by means of a suitable
crank pin, stud and connecting rod, such connecting rod being provided with a
slotted hole or groove where it is connected to the rocking lever. This groove is
for the purpose of providing the necessary dwell in the action of the rams and
ejector when clear of the moulds, to allow time to move the moulds forward to their
required position.
It will readily be seen that while the slotted part of the connecting rod is
travelling on the stud of the rocking lever, no motion from the crank wheel is
imparted to the said lever and thus I provide for the dwell necessary to move the
moulds into position.
To move the blocks or moulds the required distance I provide a cam upon the
side of the crank wheel, or otherwise which cam actuates a roller, bell crank, and
levers to which are attached suitable catches which draw the moulds forward, but
such catches are so formed that on returning they slide past the moulds until they'
engage with the next set of moulds to be brought into position.
Instead of using a cam to impart this motion I may utilize the rocking lever and
a connecting link attached to the bell crank beforementioned, but I do not bind
myself to either of these particular motions.
To drive the machine I may use the crank wheel as a pulley, friction or otherwise,
or I may provide teeth on the periphery of the same to engage in any suitable
arrangement of toothed driving gear.

Improvements in the Manufacture of Briquettes and Patent Fuel,
and in Means and Apparatus Employed therefor.
I, HERBERT JOHN REID of 32, Sackville Street, Piccadilly in the County of
London, Gentleman 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 briquettes made from coal-dust, or
any suitable mixture, and for this purpose I employ a machine of the following
description.

page_text: In describing this invention I will refer to the accompanying drawing in which
like letters denote similar parts.
Any suitable number of moulds, or blocks containing the moulds A, are
provided.
These blocks A. are connected together so as to form an endless band which
being rotated brings the moulds successively into position between a set of rams in
order that the coal-dust or other mixture may be pressed by them into briquettes
of the required shape and consistency. The endless band thus formed passes over
drums B. and is provided with guides arranged in any suitable framework C.
To fasten the blocks A forming the endless band, together I provide hinges or
lugs a and pins a' which connect to the alternate ends of the said blocks or
moulds A.
The rams for compressing the briquettes are so arranged that one ram, or set of
rams E. enters from the under side of the moulds and a second ram, or set of
rams D. enters from the top side of the moulds, the rams moving towards the
centre of the moulds and giving an equal pressure to the top and bottom of the
briquettes.
The ends of these rams D. and E. may be of a hollow or concave form so as to
shape the briquette with rounded ends, or otherwise.
To feed the moulds with the mixture to be pressed I provide any suitable
arrangement, such as a pugmill, or mechanical stoker F. placed in such a position
that as the material in one set of moulds is being pressed the one set immediately
preceeding the same is being filled by such feeding arrangement.
On the opposite side of the rams, or succeeding the same, I provide an ejector G.
by which means the briquettes are pushed out of the moulds through the under side
of the same, when they are carried away by an endless band, or shoot, or other
suitable arrangement, to any desired place.
The ejector G. is of similar construction to the rams D. and E. and passes
entirely through the moulds from the top side, in order to ensure the briquettes
leaving the moulds in every case and cleansing the same of any waste particles.
This arrangement thus provides for the feeding of one set of moulds while the
succeeding set of moulds is being operated upon by the rams and the again succeeding
one by the ejector.
I also provide an arrangement to travel the moulds so that they come successively
into position to be operated upon by the several arrangements described.
To provide for the working of the rams I arrange an upright frame connected
with the bed upon which the endless band, formed by the blocks or moulds, travels,
and in this frame I provide a centre H. upon which I place a rocking lever L. such
lever also having two centres or pivots M. and N. arranged one above and one
beneath the main centre H. and in line with the same.
To these centres or pivots M and N. are attached by means of connecting links m.
and n. and suitable pivots, the top and bottom rams before mentioned.
The bottom ram E is connected by the beforementioned means to the top centre
or pivot and the top ram D to the bottom centre or pivot.
The action of such arrangement is that when the end of the rocking lever Lis
raised the top centre or pivot M by describing an arc around the central pivot H
on which the lever L rocks, is lowered, thus bringing down the bottom ram E and
clear of the moulds, and exactly the same motion occurs but in an opposite direction,
with the top ram D.
On the rocking lever L being brought downwards to its horizontal position the
top and bottom rams D and E are forced into the moulds and the centres M and N
are in a vertical line with one another and the rams, thus providing for the least
strain on the several parts at the time of the greatest pressure in the moulds.
The rams are provided with guides P which are attached to, or form part of the
vertical framework C in order to ensure their entering the moulds centrally at all
times.
To provide for the motion of the ejector I arrange guides Q also attached to or

page_text: forming part of the vertical framework in which the ejector rams G slide and I
attach the ejector to the beforementioned rocking lever L by means of connecting
levers QQ and Q" which are pivoted to the rocking lever L the position of such
pivot Q on the lever L being determined by the amount of travel required on the
ejector rams.
To provide for the movement of the rocking lever L I arrange a crank or crank
wheel R and connected the same to the beforementioned lever L by means of a
suitable crank pin S stud T and connecting rod V such connecting rod being
provided with a slotted hole or groove W where it is connected to the rocking
lever L. This groove is for the purpose of providing the necessary dwell in the
action of the rams and ejector when clear of the moulds to allow time to move the
moulds forward to their required position.
It will be readily seen that while the slotted part W of the connecting rod V is
travelling on the stud T of the rocking lever L. no motion from the crank wheel R
is imparted to the said lever L and thus I provide for the dwell necessary to move
the moulds into position.
To move the blocks or moulds A the required distance, I provide a cam X upon
the side of the crank-wheel R or otherwise-which cam actuates a roller & and
bell crank or levers a¹ to which are attached suitable catches x¹¹ which draw the
moulds forward, but such catches are so formed that on returning they slide past
the moulds until they engage with the next set of moulds to be brought into
position.
Instead of using a car to impart this motion I may utilize the rocking lever and
a slotted connecting link attached to the bell crank before mentioned, but I do not
bind myself to either of these particular motions.
To drive the machine I may use my crank wheel as a pulley, friction or otherwise,
or I can provide teeth on the periphery of the same to engage in any suitable
arrangement of toothed driving gear.
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 arrangement of pivots placed in a rocking lever in conjunction with a
centre pivot in the said lever, connected by connecting rods to a top and bottom ram,
in the manner and for the purpose set forth and substantially described.
2. The arrangement of the ejector rams in conjunction with the rocking lever as
herein set forth and substantially described.
