Year: 1862

page_text: LETTERS PATENT to John Fowler, of Leeds, in the County of York,
Engineer, for the Invention of "IMPROVEMENTS IN ENGINES FOR HAULING
AGRICULTURAL IMPLEMENTS."
Sealed the 24th October 1862, and dated the 3rd May 1862.
PROVISIONAL SPECIFICATION left by the said John Fowler at the
Office of the Commissioners of Patents, with his Petition, on the
3rd May 1862.
I, JOHN FOWLER, of Leeds, in the County of York, Engineer, do bereby
declare the nature of the Invention for "IMPROVEMENTS IN ENGINES
HAULING AGRICULTURAL IMPLEMENTS," to be as follows:-
This Invention has for its object the so arranging an engine and winding
machinery that it may be used for hauling either the ordinary steam ploughs
or tilling implements requiring ordinary draught or drain ploughs, or similar
implements requiring a very heavy draught. Heretofore separate engines
have always been employed for these two purposes, as the gearing of the
winding or hauling drums has to be very different for ordinary ploughing or
tilling to that required for drain ploughs and similar implements, the speed
required in the former case being much greater than can be attained in the
According to my Invention I so construct the engine that it may
be used either for ordinary tilling, or for drain ploughing; this I do by

page_text: mounting underneath the boiler of the engine, and between the fore and hind
wheels two drums mounted on vertical axes, and so driven that one makes
several revolutions for each revolution of the other, the two axes being geared
the one to the other by spur wheels properly proportioned. The fast running
drum I prefer to have nipping instruments upon it, so that it may hold a
hauling rope which passes only half round it. The slow running drum I prefer
to be a winding drum, to wind or coil up the rope upon itself, but it may be a
nipping drum very strongly made. In place of mounting both the fast and
the slow drum, so that they both remain permanently on the engine, I some-
times so arrange the apparatus that the fast running drum may be removed,
and slow running drum with its intermediate gear substituted therefor, the
frame of the engine being accurately fitted and prepared to receive such parts.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Fowler in the Great Seal Patent Office on the 3rd
November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOIN
FOWLER, of Leeds, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Fowler, Her special licence that I, the said John Fowler, my
executors, administrators, and assigns, or such others as I, the said John
Fowler, my 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
ENGINES FOR HAULING AGRICULTURAL IMPLEMENTS," upon the condition (amongst
others) that I, the said John Fowler, my executors or administrators, by an
instrument in writing under my, 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.

page_text: NOW KNOW YE, that I, the said John Fowler, do bereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, that is to say :-
This Invention has for its object the so arranging an engine and winding
machinery that it may be used for hauling either the ordinary steam ploughs
or tilling implements requiring ordinary draught, or drain ploughs, or similar
implements requiring a very heavy draught. Heretofore separate engines
have always been employed for these two purposes, as the gearing of the
winding or hauling drums has to be very different for ordinary ploughing or
tilling to that required for drain ploughs and similar implements, the speed
required in the former case being much greater than can be attained in the
latter case. According to my Invention I so construct the engine that it may
be used either for ordinary tilling or for drain ploughing, this I do by mounting
underneath the boiler of the engine and between the fore and hind wheels
two drums mounted on vertical axes, and so driven that one makes several
revolutions for each revolution of the other, the two axes being geared the
one to the other by spur wheels properly proportioned. The fast running
drum I prefer to have nipping instruments upon it, so that it may hold a
hauling rope which passes only half round it. The slow running drum I
prefer to be a winding drum, to wind or coil up the rope upon itself, but it
may be a nipping drum very strongly made. In place of mounting both the
fast and the slow drums so that they both remain permanently on the engine,
I sometimes so arrange the apparatus that the fast running drum may be
removed, and a slow running drum with its intermediate gear substituted
therefor, the frame of the engine being accurately fitted and prepared to
receive such parts.
And in order that my said Invention may be most fully understood, and
readily carried into effect, I will proceed to describe the Drawings hereunto
Figure
when it is desired that the engine should be applicable both for ordinary
tilling and for drain ploughing; Figure 2 is a plan, and Figure 3 a transverse
section of the same engine.
The steam engine consists of two horizontal cylinders a mounted on the
fire-box of a horizontal boiler c of ordinary construction; d is one of the

page_text: rods of the piston in the cylinders a, and e is a connecting rod which connects
it with the crank shaft f, which is thus driven; this shaft has upon it a fly
wheel I. and also the bevilled toothed wheel ; this gears with and drives
another bevilled wheel i on the vertical axis j, which is carried by bearings on
a frame rivetted to the side of the boiler. At the lower end of this axis is a
pinion mounted loosely thereon, but capable of being made fast thereto by
nicans of a clutch actuated by the lever handle 7, the pinion gears with teeth
formed within the nipping drum m; this nipping drum is constructed in the
manner heretofore commonly practised by me, and as is well understood; this
drum is mounted on a stud or axis, one end of which is secured to the under
side of the boiler and the other to the strong wrought-iron frame n passing
under the boiler and from end to end thereof; this frame is strongly rivetted
to the boiler. On the axis of the nipping drum is a pinion n with a clutch n',
by which it can be made fast thereto; this pinion gears with and drives the
spur wheel o, which is formed on the upper part of the winding drum p; this
drum is made in two parts, as is shewn, which are firmly held together by
bolts. The engine and apparatus are mounted on four wheels, the fore pair
of which are made to lock round, the axle of the bind wheels is fixed and the
wheels turn loosely thereon; and in lieu of an ordinary friction brake on one
of these wheels a pulley is fixed at the extremity of the axle, and the wheel
is made to carry round with it a brake band surrounding this pulley; by
drawing the ends of the strap r together by the screw the movement of the
engine can be impeded. The nipping drum m is employed for ordinary steam
ploughing, and for similar purposes where considerable speed is required, and
where the strain on the rope is proportionally light; the winding drum p is
employed for drain ploughing where motion is slow, and the strain great.
The arrangement above described may be much varied, but I prefer that it
should be as I have described. As before mentioned, in place of mounting
both the fast and the slow drums so that they both remain permanently on the
engine, I in some cases so arrange the apparatus that the fast running drum
may be removed, and a slow running drum with its intermediate gear sub-
stituted therefore; this may be done by making the fixed studs or axes on
which the two drums revolve so that they may be removed from the frame
simply by taking out a key, or removing some other such like fastening.
When the fast running drum is required, it is fitted on its axis as it appears
in the Drawing, but the engine is not encumbered with the slow running
drum and gear.
When the slow running drum is to be used the other is
taken off, and its axis receives the intermediate spur gear for the slow drum,

page_text: which is then placed on its axis in the position in which it is shewn. This
arrangement lessens the weight of the engine somewhat when it is arranged
for use with the fast running drum, but on the whole I consider it less con-
venient than the arrangement which the Drawing shews.
In witness whereof, I, the said John Fowler, have hereunto set my hand
and seal, this Thirtieth day of October, in the year of our Lord
One thousand eight hundred and sixty-two.
JOHN FOWLER. (L.S.)
