page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
HUNTLEY MOHUN, of Regent's Park, in the County of Middlesex, M.D., send
greeting.
WHEREAS Her present most, Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eighth day of November, in the second year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Henry Huntley Mohun, Her especial license, full power, sole privilege and
authority, that I, the said Henry Huntley Mohun, my exors, adñiors, and
assigns, or such others as I, the said Henry Huntley Mohun, my exors, adñiors,
or assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick upon Tweed, and also in all Her Majesty's Colonies and
Plantations abroad, my Invention of "IMPROVEMENTS IN THE COMPOSITION AND
MANUFACTURE OP FUEL, AND IN FURNACES FOR THE CONSUMPTION OF SUCH AND OTHER
KINDS OF FUEL;" in which said Letters Patent is contained a proviso that I,
the said Henry Huntley Mohun, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolled in Her said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Huntley Mohun, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and. to the figures and letters
marked thereon, that is to say:
My object is
My Invention consists of certain improvements, both philosophical and
mechanical, which when combined,,have, for their object the completion and
perfection of one efficient purpose; they are, however, in many respects capable
of separation, and in parts are complete in themselves; for this reason, and in
order to render my explanation as simple and lucid as possible, I shall class
them under three distinct heads, videlicit: first, improvements in the compo-
sition of fuel; secondly, machinery for making of the same; thirdly, stoves
and furnaces for burning the same and other kinds of fuel. And first with
reference to the improvements in the composition of fuel.
attained by the combination of various animal, vegetable, and mineral sub-
stances, and matters herein-after. enumerated, to be prepared by peculiar
methods, whereby I am enabled, with celerity to make superior kinds of fuel
under several modifications; and the manner in which this is to be effected I
will now proceed, to describe. The ingredients to be used are, first, peat, peat
turf, peat earth, clay marl, slimy or other mud, alluvial deposits, or other
earths composed largely of vegetable or animal matter, or decomposed fossil
remains; secondly, .coke made from coal or peat, peat turf, peat earth, or other
earths; thirdly, animal matter or animal excrement; fourthly, green vegetable
matter; fifthly, mineral tar, coal tar, vegetable tar, asphaltum, petrolium,
naptha, mineral and vegetable pitch, resin, or any other bituminous matter, by
whatever name it may be called; sixthly, the bark of trees, or any of the
oleaginous or resinous trees, shrubs, fruits, shells, or seeds; seventhly, rosin, or
the residuum of the same, after drawing off the resinous oil.
It is necessary
here to remark, that all solids, whether of a bituminous, resinous, or oleaginous
nature, are rendered far more efficient for my purposes by subjecting them to
a peculiar process well known to chymists (and which it is not necessary here
to describe) of distillation, boiling, or otherwise dissolving, so that the fluid
property of each particular ingredient may be separated from its heavier or
more solid one. This done, the naptha or high essential oil may be reserved
for purposes unconnected with the objects herein described, and the heavier
oily matter will then be well adapted for combining with the other above-named
ingredients in the formation of fuel, according to the proportions and in the
manner herein-after mentioned. For example, many of the heavier products,

page_text: such as asphaltum or other pitchy matter, may be subjected to a process such
as is used in forming resin into oil.
The advantage to be gained by this course, is twofold. In the first place, a
liquid is thereby produced suitable for mixing with the other. ingredients of the
fuel, divested of the acid properties contained in its crude state, as the acid by:
the above process passes over with and forms a component part of the naptha,
orrlighter oil. .:. ad
gfur? T
By: these means I attain, a most important, point, videlicit, that of being
able to produce a fuel with as little as possible of acid tendency, and which
is in coals and other fuels now in use, unhealthy and highly destructive. to
metals.1.
!!
Secondly, by this process the fluid extracted from the solid matter, when in
a liquid state has greater, affinity for peat, peat turf, peat earth, clay marl,
slimy or other mud,- alluvial deposits,- or.. other.. earths, composed largely of
vegetable or animal matter, or decomposed fossil remains, or other earth, and
becomes equally diffused, over every particle of the whole mass, which would
not, be the case if used in its solid state, although a much larger quantity. were.
used in, that way!

By the means thus proposed, a. moderate proportion is rendered far more
effective, the intention being to fix the carbonaceous fluid,in the compound
and prevent its escaping, when brought into a state of combustion; thus, re-
taining its inflammable property and imparting a greater duration, to the whole
mass;. essential points are gained.. I will next describe the various modes of
combining two or more of the above ingredients in the formation of fuel and
the proportions that may be used, though it must be obvious that these
particulars; will vary according to the peculiar qualities of the several materials
or substances, the mode in which the fuel is destined for consumption, and
other circumstances; and I do not therefore confine myself to the exact pro-
portions enumerated in the several methods hereunder mentioned, nor to the
precise ingredients named in any one particular method, but I have succeeded
in making efficient fuel in the seven following methods:-
First method. Take 18, cwt. of peat, peat turf, peat earth, or other earths
composed largely of vegetable or animal matter or decomposed fossil remains,
two cwt. of clay marl, alluvial deposits, slimy or other mud, fifty lbs. of, resin
oil, mixed with fifty lbs. of liquid pitch...
:
Second method. Take seventeen cwt. of peat, peat turf, peat earth, or other
earths composed largely of 'vegetable or animal matter or decomposed fossil
remains, three cwt. of clay marl, alluvial deposits, slimy or other mud, fifteen

page_text: gallons of liquid oil from bituminous matter, after passing through the process
before referred to.
Third method. Take fifteen cwt. of peat, peat turf, peat earth, of other
earths composed largely of vegetable or animal matter, or decomposed fossil
remains, five cwt. of clay marl, alluvial deposits, slimy or other mud, and
twenty gallons of liquid tar or pitch.
Fourth method.-Take fifteen cwt. of coke, made from coal or peat, peat
turf, peat earth, or other earths, four cwt. of clay marl, slimy or other mud,
and one hundred and twelve lbs. of liquid pitch or heavy oil obtained from
bituminous substances.
Fifth method. Take sixteen cwt. of peat, peat turf, peat earth, or other
earths composed largely of vegetable or animal matter, or decomposed fossil
remains, four cwt. of clay marl, slimy or other mud, and one hundred and
twelve pounds of residuum, after the drawing off of resin oil, dissolved in ten
gallons of liquid tar.
Sixth method. Fifteen cwt. of peat, peat turf, "peat earth, two hundred
weight of other earths composed largely of vegetable or animal matter, or de-
composed fossil remains, three cwt. of vegetable matter, such as seeds, fruit,
&c., in a green or living state, or oleaginous or resinous trees, shrubs, fruit,
shells, or seeds, and one hundred lbs. of resin oil, tar, or liquid pitch.
Seventh method.-Fifteen cwt. of peat, peat turf, peat earth, or other earths
composed largely of vegetable or animal matter or decomposed fossil remains,
two cwt. of clay marl, alluvial deposits, slimy or other mud, two cwt. of animal
matter, such as contains a very large portion of oil or fat, and one cwt. of the
bark of trees, or other vegetable matter. The ingredients as enumerated in
the above respective methods of composing the fuel must be accurately united
and intimately blended, so as when perfect, to form an homogeneous mass, and
when dry they will become a hard and solid body, alike effective and durable
when in a state of combustion.
To accomplish this important object, I am compelled to have recourse to the
use of the machinery before alluded to, and classed under the second head or
item, therefore. Secondly, as to my Invention of machinery.
Having described the nature of my Invention so far as relates to the various
combinations of materials for the purpose of forming the most useful descrip-
tions of fuel, I will next give a description of the machinery employed in the
manufacture of the same, and the manner in which the various parts are
worked, illustrated also by the accompanying Drawings, to which I now
refer.

page_text: Plate No 1, the mixing mill.-Figure 1 represents the end view; Figure 2
represents the side view; and Figures 3 and 4 represent the sections of the
above, with the combination of breakers placed above the cylinder, and of
rotatory knives, moving within the body of the machine, for perfectly mixing
the ingredients.
Plate No 2, the incorporating and expressing mill.-Figure N° 1 represents
the end view; Figure N° 2 represents the side view; and Figures N° 3 and 4
represent the sections of the same.
Plate No 3 shews the apparatus and method employed in moulding the fuel
into the required form of cubes or bricks. Figure 1 is the elevation of an
equalizing frame. Figure 2 displays a side view of the pinion or motive power
with a spur wheel and crank, likewise the connecting rod attached to the
crank, with the cross rod of the pendulum beams, which gives an alternate
motion to the roller C. Figure 3 is the side view of a shaping frame, with a
shaft, upon which circular knives are fixed, in order to divide the fuel into
square or oblong cakes; these knives work the longitudinal way of the table,
and move with the same velocity as that of the table underneath. Figure 4
shews the return of the table upon a series of castors after having been relieved
of the cakes of fuel, for the purpose of being refilled.
Plate No 4, the moulding mill, shewn in section.-Figure N° 1 shews the
end view of the equalizer; Figure N° 2 shews the plan of the above; Figure
No 3 shews the end view of the shaping frame; and Figure N° 4 shews the
plan of the same. The following is the exact method by which the process of
manufacture is carried on:-The respective ingredients and quantities before-
mentioned having been proportioned either by weight or measure, let the
various substances and liquids be thrown into the hopper B of the mixing mill,
Plate N° 1, which is sufficiently capacious to contain one charge, and as
speedily as may be desired, the whole contents will have found their way into
cylinder A, after having passed through the breakers F, as seen in the two
sections, which will crush and reduce the larger pieces of fibrous and other
substances to a size and consistence fit for mixing in the cylinder.
Within the body of the cylinder there are two sets of strong knives, one
fixed and the other rotatory. C is the moveable, and D the stationary ones.
The moveable knives C are set in motion by the driving shaft I. There being
the
but little more than sufficient room for the revolving knives to pass spaces
between the fixed knives, it is evident that the whole of the enclosed matters
and ingredients within the cylinder will be put in rapid motion, and be thereby
intimately blended with each other.

page_text: 4
For the better understanding of this process, it should be premised that the
various parts of this machine are to be arranged upon different floors of the same
building. The mixing mill is to be placed upon the second floor, the incorpo-
rating mill upon the first floor, and the moulding frame upon the ground floor,
upon a level with the steam engine or other motive power which works the
various parts; consequently each-mill will empty its contents into the one imme-
diately beneath it, by means of wooden or other tubes or shoots, without any ob-
struction or loss of time or stoppage of any part of the machinery. The mixing
mill already mentioned is sufficiently powerful in its construction and action to
blend effectually the before-mentioned quantity of 'ingredients in the space of
five minutes or less time, when the attendant on the machine must loosen the
fastening W of the outlet door at the bottom of the cylinder, and the whole
contents will then fall perpendicularly into the hopper D of the incorporating
mill situate upon the floor immediately beneath the mixing cylinder. This
mill (sce Plate N° 2) is composed of three rollers, working in the direction
shewn by the arrows in the Drawings, Figure 3. Now the two uppermost
rollers work at a distance of a quarter of an inch; more or less, adjusted by
the screws G''towards each other, the effect of which motion is to draw the
exposed matters towards the centres of the rollers and reduce them to "a fine
paste, at the same time expelling the air and kneading it, as it 'were, into a
perfect homogeneous mass. The same section also shews 3 scrapers N; for
the purpose of clearing the rollers, one of which is stationed between those
two rollers which work contrary to each other, for the purpose of forcing
the substances through those which work towards each other; the other
scraper guides the paste into a shoot immediately underneath the mill, from
whence it is conducted into 'a reservoir upon the ground floor near that part of
the machine which I term the moulding mill; and here it may be observed that
I find this incorporating or rolling mill will take through and sufficiently
amalgamate thirty-five tons per hour or thereabouts, whereas the mixer
operating upon one ton in five minutes, produces but twelve tons in each hour,
or thereabouts; therefore I do not confine myself to one mixing mill, but
purpose using at one process two or more mixing mills, if necessary. The
ingredients having descended into the reservoir, which may be made of any
suitable size or form, in order to be let down as wanted to the moulding frame
(see Plates No 3 and 4), where 'G is a table resting upon friction rollers
H, H, H, with transverse partitions' equidistant from each other, and rising
through the body of the table to a level with the rim; these partitions conse-
quently form a number of parallel moulds or chambers to receive the com-

page_text: position. The fuel to be moulded is taken from the reservoir before mentioned
and laid upon the surface of the table in a proper quantity; the large roller C
is then put in motion by the perpendicular beams, to which are attached the
crank and connecting rods B, C, D, Plate No 3, Figure 2, by which an alter-
nate motion is given to the roller, the face of which, passing over the table
filled with the composition, presses it equally throughout each chamber or
division to complete the shape of a convenient form. Another division is made
in the fuel upon the table transversely to the direction of the dividing parti-
tions. The longitudinal division is given in the following manner :-See Plate
No.3, Figure 3 is a side view of the shaping frame; also Plate N° 4, Figures
3 and 4.are an end view and plan of the same. A provision is made for the
falling of the divisions in the moveable table before mentioned, by lifting the
lever M., The steady pin O is also taken out, and the plate thus relieved and
rendered capable of motion, is made to pass forward until it reaches the two.
first friction wheels H, H, Figure 3, Plate N° 3; there is a bevelled gear and
shaft E, which is driven by the upright shaft F, and which last is connected
with the engine shaft or motive power. Motion is also given to all the
friction wheels by the same means, which moving in one direction, carry the
table containing the fuel, already divided in the direction before stated, under a
shaft of circular knives B, which revolve with the passage of the fuel on the
table which runs upon the friction rollers underneath. The edges of the
circular knives entering into the fuel so as nearly to touch the surface of the
table, performs a series of cuts or divisions longitudinally in the substance
beneath. This done, the table with the fuel now complete, travels on to any
distance most convenient by an additional number of friction rollers, by an
endless cloth, or by other means, where the fuel is carried away to be dried,
either by the action of the atmosphere under a covered shed, or a room the
temperature of which is raised by artificial heat, and the vacant table is readily
made to return to the reservoir already described, to be refilled.
Figure 4, shews the plan of the table and the quantity of fuel it contains,
shaped out by the transverse partitions and circular knives; the position in
which it is seen also shews the return of the same table, when emptied, upon
a series of castors fixed against the wall, having an inclination so as to cause
its passage without other means. Several of these tables will be necessary,
according to the extent of operations and other circumstances; they may be
constructed of pine or mahogany and put together in the manner of substantial
framework. The transverse partitions I prefer to be lifted up and down with
a lever worked by hands, as it will ensure an action greater or less being given
by the large roller, according to the judgment of the workman, altho' a motion
any
Plate 3,

page_text: may be easily given, if necessary, by attaching the end of the lever to some of
the moving works. The foregoing forms the description of an entire machine,
by which the patent fuel may be efficiently produced; but in making certain
descriptions of it I prefer substituting one or both of the two following
machines (which are my entire Invention) for those parts before set forth of a
similar denomination. These are called the mixing mill No 2, and the mould-
ll Mon
with sets of knives revolving in opposite directions, is for the purpose of mixing
or amalgamating various substances and matters, as shewn in the Drawing,
put into the barrel or receiver B by means of the hopper A, which, if
necessary, may have a set of breakers (similar to those in the mixing mill
No 1) fixed in any situation between the dotted lines (in the Drawing) at this
mark. The knives N are fixed diagonally with each other. If the knives on
the shaft C are moved to revolve to the right, those in the barrel or receiver B
revolve to the left, which action is produced by two spur wheels acting on the
knife shaft wheel C, and one on the barrel wheel, all of which are marked
D1, D2, D3. The revolution of the whole is effected by any convenient
power applied to the driving drum G. The same revolution may be produced
by a power acting on a spur, crown, or bevel wheel instead of the drum G, or
the power may be applied to either the upper or lower wheel by means of a
crown or bevel. The barrel or receiver B is held in its situation by the sup-
porters K; their form should be narrow on the upper side and broad on the
under perhaps a circular or oval form would be the best. To prevent any of
the ingredients getting between the lower axles and sockets, the shields O are
fixed so as to revolve freely with their respective axles. After being thoroughly
amalgamated, the ingredients are discharged through the hopper I.

page_text: This machine may be substituted for the moulding mill N 1, and may be
worked by means of an uniforms and continued revolving motion given by any
convenient working power applied to the driving rigger A. B is the hopper
for conveying the prepared ingredients into the pressing box C and the empty
moulds D. The pressing box C is so arranged that its lower extremity presses
as close as possible against the rim of the moulding wheel E, the pressure of
which is adjusted and regulated by the adjusting screw F. As the moulding
wheel revolves, the upper part of the pressing blocks G comes in contact with
the under surface of the eccentric guide H. Before reaching the discharging
point, which is at the extreme under surface of the eccentric guide H, the
bricks of fuel I, fall immediately upon a board K, placed beneath to receive
them. The moulds D being thus cleared as they revolve, on their reaching the
spokes or rather spurs of the block pressing wheel L, it forces back the
pressing blocks G, leaving the moulds D clear and open, ready for being refilled
with composition for the fuel; the check rim M prevents the pressure of the
fuel from forcing the pressing blocks G any further. The action of the block
pressing wheel L is caused by its spurs entering the moulds D; the board K
being placed at one extremity of the upper set of rollers and endless band N, O,
is brought under the moulding wheel E by the revolution of the rollers O,
produced by a connecting band P from the rigger Q to another on the same
shaft with one of the rollers O, on the inside of which is another rigger on the
same shaft connected by the band R to the rigger attached to the shaft of the
lower roller S, giving a reverse motion to the lower set of rollers and endless
band S, T; the rigger Q is attached to the shaft of the moulding wheel E.
Upon arrival of each board filled with bricks beyond the extremity of the
upper roller, it is taken off by men or boys and conveyed away, for the purpose
of drying the fuel, after which other boards are successively placed on the
extremity of the lower set of rollers and endless band until arrival at the other
extremity of the roller, and then taken up by a man or boy and placed on the
extremity of the upper set of rollers and endless band, and so continued as
long as the machine is kept at work. The lower rollers may be omitted, like-
wise the spur wheel J. A. roller may be placed at the lower extremity of the
pressing box C against the rim of the moulding wheel E, either with or with-
out a spring, to press the roller against the rim of the moulding wheel, or a
spring only may press against the moulding wheel. A sieve may also be added
for sifting charcoal or ashes over the empty moulds. It may be placed over
the moulding wheel by attaching it to the inside of the hopper B. A

page_text: vibrating motion can be given to it by a connection with any of the riggers as
may be most convenient, but this addition is unnecessary if the bricks of fuel
fall readily by their own gravity, on being pressed clear out of, the moulds;
otherwise I should prefer placing-a thin piece of steel or a wire against the
rim of the moulding wheel at or near the falling point of the eccentric guide H.
This can be applied at any time in a. few minutes by fixing the wire in any
convenient. manner to the bearings on each side of the moulding wheel E;
the eccentric guides may be fixed in any convenient manner that is best suited
for it on the bearings U; the greater portion of the form is quite immaterial,
but the point of discharge and a quarter circle of it should be particularly
attended to; moreover spur wheels may be made to work the rollers and end-
less chains, if preferred to working them by riggers and bands. .

These two last mentioned machines may be used either together or separately
with the incorporating machine before described.
Thirdly, as to my improvements in stoves or furnaces for burning my patent
fuel above described and other kinds of fuel. My Invention consists in the
phylosophical and mechanical construction of a furnace, by means of which I am
enabled to supply a larger portion than ordinary of atmospheric air conveyed
in a heated state to support the combustion of the fuel contained in the fire
box of the same, and by which a rapid and intense evolution of caloric is pro-
duced. As it is difficult in this place to describe the peculiar shape or forma-
tion of the furnace, I beg to refer to the Drawings which accompany this
Specification, by which the nature of the same will more clearly appear.
A, A, A, are openings leading to the cylindrical flues; the transverse section
shews the course of the two side or outer flues, and the longitudinal section
shews the course of the centre flue, the arrows indicating the progress of the
atmospheric air which enters at last through the bars to the fire box, and is

page_text: there absorbed by the fuel. B is the outer opening door to supply the fuel,
which opening closes an inner door, connected by a short bar and a hinge to it
to prevent the admission of cold air whilst this operation is going forward; C,
the ash pit under the bars; D, cylindrical flues formed of iron; E, the fire
box; F, the flues above the fire to carry off the product of combustion; G, a
waggon-shaped boiler, with H a flue 'through its centre. These are no part of
my Invention, but are merely placed in connection with the furnace to shew
the mode in which they may be set. The action of the furnace is as follows:-
The fire being lighted, that part of the cylinder next thereto becomes heated,
and the air, by absorbing the caloric in its passage, expands, whereby a tendency
to a vacuum is created and the external air presses forward with continued
force, and by the same means acquires a similar heat, so that no cold air enters
the fire. By this continued stream of air 'the destruction of the metal is also
prevented, and by making the cylinders longer and higher, any extent of power
may be given. For domestic stoves I adopt the same principle, only instead
of having the front of the stove closed, I leave it open, with bars; so as to pre-
sent a view of the burning fuel; but in order to preserve the draft of air up
the side and back cylinders, I place before the bars just mentioned a second
grating with bars placed transversely, about five or six inches distant 'from
those containing the fuel. The shape of the stove in other respects, as well as
its ornaments, may be varied according to taste. The flues may be differently
constructed above the grate, according to the purpose for which the stove may
be intended, but the method of conveying the air and heating it as it travels
towards the fuel, is the principle which it is important to pay the strictest
attention to. My present improvements of the composition of fuel described
in my former Patent consists principally in substituting the peculiar process of
liquifying the bituinenous acid resinous substances (according to the process
above mentioned) for the mere crushing of the same, the more perfect combi-
nations and proportions described in the several above methods of making the
fuel, and dispensing with the several articles not included in my present Speci-
fication, together with the peculiar improvement to be grained by manu-
facturing it by means of my machinery above described, whereby I am enabled
to produce a fuel divested of acid tendency, of a perfectly homogenous con-
sistency, and possessing a more intense and lasting effect.
Having thus described the nature of my present Invention, and several
parts thereof as it regards the materials, substances, and ingredients, and the
different proportions thereof to be used in the manufacture of my fuel accord-
ing to the seven several before-mentioned methods, also the machinery to be
used in the manufacture of the same, and stove or furnace for the burning of

page_text: the same and other kinds of fuel, I would state that I do not lay claim to
every part of the said machinery separately as my Invention, as many of the
parts, both separately and in connection with each, have been used before; but
what I claim are the several improvements in the various proportions and mode
of combining the various ingredients on my fuel, as above described, and the
effects produced by the use of the said machinery in the manufacture of the
same.
I also claim as my Invention the results obtained by the burning of the fuel
so combined and manufactured in my said stove or furnace.
I also claim the combination of the machinery as shewn in Plates 1, 2, 3,
and 4, as new in its application to the making of fuel.
I also claim the process of pressing by rollers in the manufacture of
fuel, whereby the ingredients are more completely combined and the air
expelled.
I also claim as my entire Invention the principle, movements, and com-
bination described and contained in the mixing mill N° 2.
I also claim as my entire Invention the principle and construction of the
moulding mill N° 2.
And, lastly, I claim the principle and peculiar construction of my stove and
furnace as never having been before in such a manner used and practised.
In witness whereof, I, the said Henry Huntley Mohun, have hereunto
set my hand and seal, this Eighth day of May, One thousand eight
hundred and thirty-nine.
