Improvements in Machinery for Agglomerating Fuel and other
Substances.
JOHN STURDY HALL and CHARLES EDWARD VINCENT HALL, Engineers of
Midland Iron Works, Newark-on-Trent, and PHILIP RUDOLF BJÖRLING, Engineer,
of 17, Strathblaine Road, New Wandsworth, London, S.W., do hereby declare
the nature of this invention to be as follows:-
Our invention relates to agglomerating fuel and other substances in a simple
manner and with an inexpensive, compact machine, hereinafter described and
claimed, having for its object to avoid pressure on the bearings, to cause the
cavities or recesses in the moulding cylinders to always coincide exactly one with
the other, whereby seams or unsymmetrical formation of the ovoids are avoided,
and generally to form a complete and efficient machine, which shall be easily
transported in parts or as a whole. This object we arrive at by the method we
adopt in driving two rollers, provided with cavities and equal to half the ovoid.
These rollers we drive by means of two worms and two worm-wheels, either right-
or left-handed, as found most convenient. The wormspindles are rotated by
means of bevel or mitre wheels, as may be most suitable for the driving power,
The bevel or mitre-wheels are again actuated by a bevel- or mitre-wheel keyed
on to an upright shaft, this shaft also drives a feed-mill placed on the top of
the rollers for securing a sufficient pressure on the material to be agglomerated.
This feed-mill may be furnished with a steam-jacket, if necessary.
The system of driving may be varied slightly according to the position of
the driving power, and other circumstances, but we strictly adhere to the rolls,
and the manner in which we obtain the reverse motion of the rolls, by means
of three mitre-wheels, or two bevel-wheels and one bevel-pinion, or two bevel-
pinions and one bevel-wheel, together with the aforesaid two worms, and two
worm-wheels, either right or left-handed.

page_text: 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 follow-
ing statement:-
Our improvements relate to machinery for agglomerating fuel or other sub-
stances and consists in certain improvements hereinafter described and, claimed,
having for their object to avoid pressure on the bearings, to cause the cavities
or recesses in the moulding rollers to always coincide exactly one with the other,
whereby seams or insymmetrical formations of the ovoids are avoided, and
generally to form a complete and efficient machine, which shall be easily trans-
ported in part or as a whole. This object we arrive at by the method we adopt
in driving the rollers, provided with cavities, of any size or shape, each cavity
being equal to half the fuel.
Referring to the accompanying drawing Sheet Number 1; Figure 1 is an
clevation and Figure 2 a plan.
The machine consists of two rollers A and A, which work in contact; the faces
of these rollers are furnished with recesses, with as little space as possible between
them; these recesses or cavities are made of any size or shape for producing any
kind of fuel that may be required.
The rollers are both indentical with one another, and the fuel is produced by
the pressure obtained when the paste passes down the hopper, C, between the
two rollers.
When the bond or binding material, that is required to be pressed hot, is
adopted we make the rollers hollow and admit steam into them through the roller
spindles.
The rollers are driven by means of two worms, B and B, and worm-wheels 1)
and D, either right or left-hand, as found most convenient for driving. The
worm-spindles are rotated by means of bevel- or mitre-wheels, E and E, as may
be most suitable for the driving power, and the different speeds of the rollers
and the motor. The bevel or mitre-wheels are again actuated by a bevel- or
mitre-wheel keyed on to an upright shaft F, this shaft also drives a feed-mill
or mixer, G, placed on the top of the rollers, for securing a sufficient pressure
on the material to be agglomerated. This feed-mill, G, may be steam jacketed
if necessary depending upon what nature of bond or binding material is
employed. In some instances, and for some bond or binding material, the feed-
mil or mixer may be omitted, that is to say, when the binding material is not
sticky, so that it will enter the space between the top part of the rollers by its
own gravity.
The system of driving may be varied slightly according to the position of the
driving power, and other circumstances, but we strictly adhere to the manner
in which we obtain the reverse motion of the rollers. Some times we may drive
the machine by a belt-pulley, H, working a horizontal shaft. J; this shaft again
having keyed on it a bevel- or mitre-wheel; L is a bevel- or mitre-wheel keyed
on to the upright shaft F. In such cases we may work a travelling belt from
the shaft, J, for conveying the fuel from the machine. At other times we may
key a pulley direct on the upright shaft, F, and work by a half crossed belt
direct from the motor. By this arrangement of gearing, we can, by shifting
either wheel or pinion the space of one tooth, adjust the position of the moulds
or cavities in the roller ud of an inch, and by that means preventing insym-
metrical formations of the block fuel.
Having now particularly described and ascertained the nature of our said
invention and in the manner the same is to be performed, we declare that what
we claim is:
In agglomerating machinery
1. The combination with the rollers, worms and worm-wheels for operating
the said rollers, substantially as herein before described.

page_text: 2. The combination of rollers, worms and worm-wheels, the worms and worm-
wheels being both either right- or left-handed, the worms being keyed on separate
spindles.
3. Actuating the worm-spindles, either by bevel-wheels or mitre-wheels, sub-
stantially as herein before described.
4. The upright shaft for working both the worm-spindles and the beaters in
the feed-mill, substantially as herein before described.
5. The horizontal shaft, rotated by the motor by means of a pulley, for actuating
the upright shaft, the horizontal shaft also being adopted for working the travelling
belt or conveyor, when used substantially as herein before described.
6. Machines for producing briquelles, brickets or patent fuel, of any description,
without the use of steam or any other kind of heat; the fuel being made of any
kind of material or vegetable substances, substantially as herein before described.
