WHEREAS Her present most Excellent Majesty Queen Victona, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Butain and Ireland, bearing date at Westminster, the Second day of June, in
the ninth year of Her reign, did, for Iciself, Hei heirs and successors, give and
grant unto us, the said William Stubbs and John Isaiah Grylls, our exors,
adiňors, and assigns, Ier especial licence, full power, sole privilege and
authority, that we, the said William Stubbs and John Isaiah Grylls, our exors,
adiñors, and assigns, or such others as we, the said William Stubbs and
John Isaiah Grylls, our exors, adiñors, or assigns, should at any time agiee
with, and no others, fiom 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, our
Invention of "IMPROVEMENTS IN LOCOMOTIVE AND OTHER ENGINES AND CARRIAGES,"
in which said Letters Patent is contained a proviso that we, the said William
Stubbs and John Isaiah Grylls, shall cause a particular description of the
nature of our said Invention, and in what manner the same is to be performed,
by an instrument in writing under our hands and seals, or under the hand
and seal of one of us, to be inrolled in Пer 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, icference
being thereunto had, will more fully and at large appear.

page_text: our said Invention, and the manner in which the same is to be performed, are
fully described and ascertained in and by the following statement thereof,
reference being had to the Drawings hereunto annexed, and to the figures
and letters marked thereon, 'that is to say :-
DESCRIPTION OF THE DRAWINGS No. 1, No. 2, and No. 3.
No. 1 shews a longitudinal section of a locomotive engine constructed
according to part of our improvements, having diving wheels twelve feet in
diameter The object of our improvements is high speed with stability; and
in order to gain an efficient boiler, we have arranged it with two large external
tubes, M and E The lower part or tube, marked M, M, M. contains the
small tubes or tubular flues, connected with the fire and smoke boxes through
which the heated an and flame passes to the smoke box S. The other tube, E,
is a division of the boiler above the main axle for a steam reservoir, which is
connected with the fire box shell at-one end and the smoke box at the other
end N, 2, N, are moveable pieces above the main axle, to be removed if
necessary when the wheels and axle are taken out or put in; F is the steam
pipe to convey the steam to the cylinders from the steam dome through the
steam reservoir E; H is the fire box, I, 1, is the recess in the hic box for the
axle, O, of the small wheels, A, A. are the cylinders placed in the sinoke box S,
as shewn, B, B, are the two pistons, Cand e Pare the piston rods The 1od
c P' being hollow, and the 1od C works through it, and they are connected with
their respective cross heads, D, D At the centre of the cylinders A, A, the
partition W is applied, and is made steam-tight by metallic packing U, round
the solid rod C. The cross heads are supported on longitudinal guide bars Q, Q,
in the usual way, the ends of the cross heads are connected with the crank
pins T, T, T, T, by suitable connecting rods.
No 2 shows a plan of the locomotive engine, and No. 3 shows the two end
Views of the locomotive engine The Drawings do not show several of the
details, they being well understood, and therefore do not require to be shown
This mode of ananging the cylinders can either be used with crank pins, as
shown and described, or with an excentric and pin, or two excentrics on cach
side at night angles, as hereafter described in respect to another part of the
Invention.
It should be stated that the same letters of reference in the above-mentioned
Diawings refer to the same parts, and we would state that the details of the
locomotive engine, above described, may be vaned without departing from the

page_text: Invention, so long as the peculiar character of the combination and construction
of the parts be retained
And we claim, in respect to the first part of our Invention, the mode of
constructing the boiler of two tubes, and in such manner as to allow of
introducing the wheel axle, as described, and also the mode of constructing
and applying the engines. In the Drawing No. 3, Figure 1 shows the smoke
box end, and Figure 2 the fire box end of the sanie engine, No. 4.
DESCRIPTION OF THE DRAWING NO 4,
Which shows a longitudinal soction of another arrangement of locomotive
engine. The two cylinders are placed underneath the boiler. In this engine
four of the wheels are connected by side 1ods with the cross heads of the two
cylinders, and in such manner that each cylinder dives two wheels, each
cylinder moving a cross head, and each cross head by two connecting rods
moving the wheels II is the fire box, and H' is a tube or continuation of the
fire box This fire box differs from those at present in use inasmuch as the
part H projects into the cylindrical part of the boiler two, three, or more feet,
as may be necessary. The object of this improvement is to remove the ends
of the small fluc tubes to a distance from the direct action of the fire, and by
such means a saving will be effected in their durability The arrangement of
cylinders shown in this Drawing will be found very convenient, and at the
same time it will tend to prevent side oscilation in the locomotive engine
What we claim as the second part of our Invention is the mode of arranging
the cylinders and cross heads, and also the applying the part II' to the fuc box
of a locomotive engine.
DESCRIPTION OF THE DRAWING No. 5.
The boiler and tube of the engine shewn this Drawing is very similar to
that described in respect to the Drawing No 4, with this important difference,
that the boiler and tube are recessed underneath to admit of the lowering of
the boiler, and yet allow of employing wheels of large dimensions; the diameter
of the wheels shewn is nine feet, but this part of the Invention can be used
with diving wheels of other diameters, for the purpose of reducing or bringing
down the centre of gravity. II is the fine box, and tube H, I, I, is the recess,
and O is the axle of the driving wheel This Drawing does not show the
cylinder, and we prefer for this engine to use outside cylinders, as is well
understood
And we claim as the thund part of our Invention the recessing of the boiler
and tube H', in order to lower the boiler and consequently the centre of gravity
of a locomotive engine.

page_text: DESCRIPTION OF THE DRAWINGS No. 6, No 7, and No 8,
Which represent our improved mode of driving engines by excentrics, and
which is applicable generally to engines where cranks or excentrics are used.
Figure 1 is an edge view of the eccentric C, with its strap A, and friction
rollers B, which we prefer to be with mite edges. D is the axle on which
the eccentric is placed and fixed. The strap A is made in two halves, and
brought together and fastened by the screw bolts E, E, E, E, E. The mitre
edge of the sheaves are to aid in adjusting the wear of the rollers and strap, and
will allow of tightening up when necessary, there being a space left for that
purpose betwixt the strap
Figure 1, Diawing No. 7, is a side view of the eccentric with four 1ollers B.
but the number may be varied. These rollers are cylindrical where they come
against the surfaces of the straps, and they come together in two halves, as
shewn on the sketch
Figuic is a similar arrangement to that shown in Drawing No 6, having
fom 1ollers B
Figure 3 is a fiont view of an apparatus with the rollers B, inserted in a
ring a, the excentrix and the stiap being grooved to receive the rollers
It may here be proper to add, that we do not confine ourselves to any
number of rollers B, in each excentric apparatus, or the particular form or
shape of the working surfaces of the rollers
Figure 1, Diawing No 8, shows an edge view of a diving wheel of a loco-
motive engine with two excentrics, to be used in place of the crank pins in
Diawings No. 1, No. 2, and No 3 A, the driving wheel, B, B, the edge
view of the excentrics.
Figure 2 is a fiont view of the wheel and excentrics A, the driving wheel,
B, B, the excenties; C, the end of the main axle.
What we claim as the fourth part of our Invention is, the application of
apparatus cons.sting of an eccentric, a stiap or straps, and rollers for driving
in place of cranks as herein described
DESCRIPTION OF THE DRAWING No. 9
Figure 1 is the outline of a novel construction of boiler, with double body,
suitable for locomotive engines, to be used on wide guage railways. A is the
fire box shell, B, B, the two bodies of the boiler.
What we claim as the fifth part of our Invention is, the construction of
locomotive engine boilers with double bodies.
Figure 2 is the outline of an eight-wheeled carriage for railways. The object
