PROVISIONAL SPECIFICATION left by the said Alfred Fernandez Yarrow
and James Bracebridge Hilditch at the Office of the Commissioners of
Patents, with their Petition, on the 2nd November 1861.
We, ALFRED FERNANDEZ YARROW, of Arundel Square, Barnsbury, Engineer,
and JAMES BRACEBRIDGE HILDITCH, of Barnsbury Villas, Gentleman, both in
the County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY USED WHEN PLOUGHING, TILLING, OR CULTIVATING
LAND BY STEAM POWER," to be as follows:-
This Invention has for its object improvements in machinery used when
ploughing, tilling, or cultivating land by steam power, & consists in
improved methods of combining winding barrels or drums with portable steam
engines.
In carrying out the first part of our Invention, we mount two winding
drums on a horizontal shaft or axis which is situated on one side of a portable
engine; upon one side of each of these drums are bevel teeth which are made

page_text: to gear alternately with two bevel wheels which are driven by a bevel shaft.
At the upper extremity of this bevel shaft is attached a bevel wheel, which
gears into a bevel wheel which is fixed on the engine shaft.
In the second part of our Invention we attach a large bevel wheel upon the
horizontal shaft, which is situated on one side of the engine; we also place
a barrel or drum upon each side of this wheel, to which they may be alter-
nately connected. The large bevel wheel is driven by means of a smaller
bevel wheel which is fixed on a bevel or vertical shaft, which itself is driven
from the engine shaft by a pair of bevel wheels. The horizontal shaft upon
which the large bevel wheel is fixed may be continued on towards the hinder
part of the engine where a bevel wheel is attached to it, which wheel may be
thrown in gear, when desired, with another bevel wheel which is connected
either to the driving wheel or axle of the engine for the purpose of propelling
such engine.
The third part of our Invention is as follows:-Upon the horizontal shaft,
which is situated on one side of the engine, we fix a large bevel wheel, which
is driven by means of a smaller bevel wheel which is fixed on a bevel or
vertical shaft, which itself is driven from the engine shaft by a pair of bevel'
wheels. Upon the horizontal shaft is a clutch, and on each side of the clutch
is a drum, which may be alternately thrown in gear in the usual manner.
The horizontal shaft may be continued towards the back part of the engine,
and arranged to render the engine locomotive in a similar manner to the
In both these three arrangements, either of the drums may be
rendered the hauling drum whilst the rope is uncoiling from the other.

page_text: bridge Hilditch, our executors, administrators, and assigns, or such others as
we, the said Alfred Fernandez Yarrow and James Bracebridge Hilditch,
our executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY
USED WHEN PLOUGHING, TILLING, OR CULTIVATING LAND BY STEAM POWER," upon
the condition (amongst others) that we, the said Alfred Fernandez Yarrow
and James Bracebridge Hilditch, our executors or administrators by an
instrument in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Alfred Fernandez Yarrow and
James Bracebridge Hilditch, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This Invention has for its object improvements in machinery used when
ploughing, tilling, or cultivating land by steam power, and consists in
improved methods of combining winding barrels or drums with portable steam
engines.
In carrying out the first part of our Invention, we mount two winding
barrels or drums on a horizontal shaft or axis which is situated on one side
of a portable engine; upon one side of each of these drums are bevel teeth
which are made to gear alternately with two bevel wheels which are driven
by a bevel shaft. At the upper extremity of this bevel shaft is attached a
bevel wheel which gears into a bevel wheel which is fixed on the engine
shaft.
In the second part of our Invention, we key a large bevel wheel upon the
horizontal shaft, which is situated on one side of the engine; we also place a
barrel or drum upon each side of this wheel, to which they may be alternately
connected. The large bevel wheel is driven by means of a smaller bevel
wheel which is fixed on a bevel or vertical shaft, which itself is driven
from the engine shaft by a pair of bevel wheels. The horizontal shaft upon
which the large bevel wheel is keyed is continued on towards the hinder
part of the engine where a bevel wheel is attached to it, which wheel
may be thrown into gear with another wheel which is connected either to.

page_text: the driving wheel or axle of the engine for the purpose of propelling the
engine.
In the third part of our Invention upon the horizontal shaft which is
situated on one side of the engine we fix a large bevel wheel which is driven
by means of a smaller bevel wheel which is fixed on a bevel or vertical shaft
which itself is driven from the engine shaft by a pair of bevel wheels; upon
the horizontal shaft is a clutch, and on each side of the clutch are the drums,
which may be alternately thrown in and out of gear in the usual manner.
The horizontal shaft may be continued back towards the back of the engine,
and arranged to render the engine locomotive in a similar manner to the
former case. By these arrangements either of the drums may be rendered
the hauling drum whilst the rope is uncoiling from the other.
And in order that our said Invention may be fully understood, we shall
now proceed more particularly to describe the same, and for that purpose
we shall refer to the several Figures on the Sheet of Drawings hereunto
annexed.
Fig. 1 represents an arrangement of drums carried out in accordance with
the first part of our Invention. a is a bevel wheel fixed on the engine shaft ;
b is a wheel which gears into a, and is fixed on the shaft e; c and c¹ are two
wheels fixed at the other end of the shaft e, and are constructed to gear into
the teeth d and d¹, which are fixed firmly to the drums f and f¹; g is the
axis upon which the drums revolve, and is supported at hand h¹ by brackets
fixed to the boiler; the lever i, j, is connected with the axis g, so that by
moving it the drums can be alternately thrown in and out of gear. In this
Figure the crank shaft is placed on the right hand side of the boiler, but if
the cylinders be placed in the smoke-box, the position of the crank shaft will
be altered, and the direction of the shaft e must be made to suit.
Fig. 2 represents a mode of driving the drums, and rendering the engine
in accordance with the second part of our Invention. a is a bevel wheel
fixed on the engine shaft b, a wheel which gears into it, and fixed on the
shaft e; c is a wheel which is fixed at the lower extremity of the shaft e, and
gears into the wheel d; on each side of d are the drums f and f', either of
which can be thrown into gear with the wheel d by means of the clutch h.
The wheel d is keyed on the shaft g, but the drums f and f¹ run loose on it;
the shaft g revolves in bearings fixed by means of brackets to the boiler. At
the fire-box end of the shaft g is a bevel pinion j, which can be thrown into
gear by means of the clutch i; this pinion gears into the bevel wheel k, which
is firmly fixed to the driving wheel l, or to the main driving axle. The
clutches & h can be shifted according to some well known method. If

page_text: the crank shaft of the engine be placed near the smoke-box, as in Fig. 1,
the position of the shaft e will have to be altered to suit.
Fig. 3 represents a mode of driving the drums, and rendering the engine
locomotive in accordance with the third part of our Invention. a is a bevel
wheel, fixed on the engine shaft b a wheel which gears into it, and keyed on
the shaft e; c is a wheel which is fixed at the lower extremity of the shaft e,
and gears into the wheel d, which is keyed on the shaft g; the drums f and f¹
run loose on the shaft g, but can be thrown into gear with it by means of the
clutch h; the shaft g is continued back, and the engine rendered locomotive
in a similar manner to Fig. 2 by means of the clutch i and the wheels j and k.
If the crank shaft of the engine be placed, as in Fig. 2, the position of the
shaft e will have to be made to suit; the wheel d may be placed on the fire-
box side of the drum f.
Having thus described the nature of our Invention, and explained the
manner of carrying the same into effect, we would have it understood that we
do not claim any of the mechanical parts separately, nor do we confine our-
selves to the details; but what we claim, are,-
Firstly, the modes of combining winding barrels or drums with portable
engines and of driving the same, as herein described.
Secondly, the method for rendering the engine locomotive through the
medium of the drum shaft, as herein described.
