page_text: LETTERS PATENT to George Taylor Yull, of Neutra, in the Kingdom
of Hungary, at present residing at Bedford, in the County of
Bedford, Agriculturalist, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR RAISING, LOWERING, MOVING, OR TRAN-
SPORTING HEAVY BODIES, APPLICABLE ALSO TO LAND CULTIVATION BY STEAM OR
OTHER POWER."
Sealed the 11th May 1875, and dated the 12th November 1874.
PROVISIONAL SPECIFICATION left by the said George Taylor Yull
at the Office of the Commissioners of Patents, with his Petition,
on the 12th November 1874.
I, GEORGE TAYLOR YULL, of Neutra, in the Kingdom of Hungary,
5 at present residing at Bedford, in the County of Bedford, Agriculturalist,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR RAISING, LOWERING, MOVING, OR TRANSPORTING
HEAVY BODIES, APPLICABLE ALSO TO LAND CULTIVATION BY STEAM OR OTHER POWER,"
to be as follows:-

This Invention relates to a simple and effective arrangement of wind-
lass, whereby a greater amount of power is obtained with a smaller
amount of gearing than has heretofore been employed.

page_text: According to my Invention I mount one or more. windlass drums or
barrels upon a shaft, and upon this shaft I also fix a large worm wheel.
Into the teeth of this worm wheel gears a worm or endless screw
mounted on a shaft at right angles to the windlass shaft. This worm
shaft may be driven either direct or otherwise by hand, steam, or other
power, and imparts a slow but powerful rotatory motion to the windlass
drums or barrels without the intervention of intermediate gearing of any
kind. Upon the windlass barrel the hoisting or hauling ropes or chains
are wound, one barrel if desired being made to pay out the rope or chain
whilst the other is winding on.
In some cases when using a single drum or barrel, and where it is
desirable to throw the driving gear out of action, I mount the worm
shaft in sliding or adjustable bearings to admit of the worm being lifted
out of gear with the teeth of the worm wheel. In this case the usual
break is combined with the windlass to control the reverse speed of the
barrel or drum.
In applying my improved windlass to the purposes of cultivation by
ordinary portable steam engines I mount the shaft which carries the
drums and worm wheel in a frame, which I bolt, brace, or secure in any
other convenient manner to the boiler or fire-box of the engine. The
worm shaft is driven direct from the crank shaft of the engine by a belt,
pitch chain, and pullies, or by toothed gearing, as found most con-
venient. When applied in this manner to the hauling of ploughs or
other implements employed in the cultivation of land I prefer to employ
double drums or barrels attached to engines on opposite sides of the field
and working two implements, the hauling chains or ropes being wound.
in opposite directions on the two drums, so that one drum will be hauling
whilst the other is paying off the slack or tail rope. By this arrange-
ment breaks are dispensed with, and the pull of the slack rope assists
the winding in the opposite direction.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Taylor Yull in the Great Seal Patent
Office on the 12th May 1875.

page_text: residing at Bedford, in the County of Bedford, Agriculturalist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of November, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Taylor Yull, Her special
license that I, the said George Taylor Yull, my executors, admini-
strators, and assigns, or such others as I, the said George Taylor
Yull, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 OR APPARATUS FOR RAISING, LOWERING, MOVING,
OR TRANSPORTING HEAVY BODIES, APPLICALLE ALSO TO LAND CULTIVATION BY STEAM
OR OTHER POWER," upon the condition (amongst others) that I, the said
George Taylor Yull, 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.
NOW KNOW YE, that I, the said George Taylor Yull, do hereby
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 statement thereof, reference being had to the
accompanying Sheet of Drawings and to the letters and figures marked
thereon, that is to say:
My said Invention relates to a simple and effective arrangement of
windlass and driving gear, combined with a portable steam or traction
engine, for the purposes of hoisting or hauling, but more especially
applicable to steam cultivation.
In carrying out my said Invention I mount a shaft carrying the
winding drums in a frame, which frame I bolt, brace, or secure in any
convenient manner to the boiler, axles, or frame of a portable or traction

page_text: engine so as to be readily attached and detached therefrom, whereby the
said engine can be used when required for all other purposes without
incumbrances, and when employed for steam cultivation serves and acts
as an anchor. The said windlass shaft carries also a worm wheel, spur
wheel, bevel wheel, chain wheel, or other suitable mechanical contrivance,
which is driven from a worm or endless screw or toothed gearing or
chain, carried either on the end of the crank shaft itself of the engine
or on a counter shaft mounted in bearings in the before-mentioned
frame. The said counter shaft is driven direct from the crank shaft
by pitch chain and pullies, toothed gearing, or otherwise, as found most
convenient. When applied in this manner to the hauling of ploughs or
other implements employed in the cultivation of land I prefer to employ
double drums or barrels attached to engines on opposite sides of the
field and working two implements, the hauling chains or ropes being
wound in opposite directions on the two drums, so that one drum will
be hauling whilst the other is paying off the slack or tail rope. By this
arrangement the breaks, which are required when loose drums are used,
are dispensed with, and the pull of the slack rope is utilized so as to
assist the winding in the opposite direction.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the explanatory Sheet of Drawings
hereunto annexed, the same letters of reference indicating corresponding
parts in all the Figures.
Figure 1 of my Drawings represents a side elevation of an ordinary
portable steam engine, having a hauling or winding tackle fitted thereto
in accordance with my said Invention; Figure 2 is a corresponding plan
of the same; Figure 3 is an end elevation looking upon the fire-box
and corresponding to Figure 1, a portion of the winding drum being
broken away to show one mode of driving; and Figure 4 is a detail
showing a modified arrangement of the drums and actuating worm
wheel.
A, A', is the boiler of an ordinary portable engine, the engine itself
being omitted, as being well understood; B is the crank shaft, which
may be mounted in bearings in the usual manner, and may be formed
with a single or double crank, as found desirable.
In the arrangement shown in my Drawings I employ a separate worm
shaft C, which is represented as being driven direct from the crank shaft

page_text: by a pitch chain D (shown in dotted lines) gearing into chain wheels E
and F mounted respectively on the crank shaft B and worm shaft C.
The latter shaft is supported in bearings a, a¹, carried in brackets or
subordinate frames bolted to the main frame G of the winding tackle.
This frame is by preference jointed by the bolt 6 to the ends of two
transverse bars H, which are braced to the front and rear of the fire-box
portion of the boiler by the long screw bolts c, c, thus affording facility
for the ready removal and readjustment of the tackle when required for
use, it being simply necessary to slacken the nuts of the bolts c, c, or to
withdraw the bolt 6, which forms the fulcrum or hinge pin of the
frame G in order to detach the entire winding or hauling tackle from the
engine.
If desired the frame G may be formed in one with the transverse
bars H, in which case it will be rigidly attached to the boiler, but I
prefer to connect such frame by a joint, substantially in the manner
shown in my Drawings, whereby the said frame is left free to rise or fall
over any unevenness in the surface of the ground. For this purpose,
and with a view to prevent any downward pull upon the engine from the
upper rope which might tend to displace it, I mount in the front
portion of the frame G a supporting wheel I, which travels along the
ground and takes any downward strain 'exerted upon the frame G. On
a horizontal shaft K fitted in the said frame I mount a flanged winding
barrel or drum, which is divided into two sections L and M by a central
flange, these sections being worked either together or separately. On
these sections L, M, ropes or chains N and O are wound, but in opposite
directions on each section, the rope or chain on the section L entering
the drum from below, for example, whilst that on the section M enters
from above, as is clearly shown in Figures 2 and 3. The supporting
wheel I is so disposed in front of one of the two sections of the winding
drum as not to interfere in any way with the course of the rope or chain,
as will be readily seen on referring to the Drawings. On one end of the
winding barrel or drum I have shown attached a large worm wheel P,
into the teeth of which gears a worm or endless screw Q mounted on
the worm or counter shaft C, before referred to. When required for the
purposes of steam cultivation I prefer to employ a second portable engine
and hauling tackle, such as I have described above, on the opposite side
of the field, the rope or chain which is being unwound from one drum
being wound on to the corresponding drum of the opposite engine, and
vice versa, each rope hauling an implement of its own.

page_text: When the ploughs or other cultivating implements have completed
half the distance from one engine to the other the motion of the engines
is reversed, and the said implements having been adjusted for the return
traverse are hauled back again; but in the case of drilling and harrowing
the implements should travel the entire course from engine to engine
before being reversed.
In lieu of using a reversing gear on the engines it is obvious that any
suitable or well known reversing gear can be employed in connection
with the drums.
In the modified arrangement of winding drums and worm wheel,
shown in Figure 4, I mount the worm wheel P fast on the drum shaft K
and employ two distinct drums L and M, which are mounted loose on
the said shaft, and are capable of being thrown in and out of gear
respectively with projections d, d, or with recesses in the sides of the
worm wheel; thus one drum may be left free to pay off the rope or
chain before commencing work, whilst the other drum (after the work
is finished) may be kept in gear for winding up the tail rope left on the
field. The drum shaft K is of sufficient length to receive a pair of
common travelling wheels, one at each end, for the purpose of tran-
sporting the drums and frame when detached from the engine.
In some cases I attach the removeable frame G carrying the winding
drums and gearing to either end of or to the side of the barrel A¹ of the
boiler, or to the axles or framing of the same by jointed metal straps or
otherwise, so as to be easily detached when required, and I mount the
driving worm or endless screw Q on the end of the crank shaft itself,
such screw gearing direct from the crank shaft into the worm wheel P
on the drum shaft, which is conveniently placed for the purpose. In
this case all intermediate gearing between the crank shaft and the worm
wheel P is dispensed with.
Although I have more particularly described and illustrated the use
of a screw and worm wheel for driving the winding drums, I do not
confine myself thereto, as it is obvious that bevel or other gearing may
be substituted therefor.
When using common portable engines, such engines when at work on
the field are caused to travel forward on the headlands as the work
proceeds, either by driving the "off" hind wheel from the work by the
aid of an ordinary pitch chain from the crank shaft or by a ratchet and
pall motion derived from an eccentric on the said shaft.

page_text: By passing the winding-on rope under or over suitable guide pullies it
is obvious that the engine with its winding gear attached thereto, as
above described, may be used for the purposes of lifting or lowering
heavy bodies, or for moving or hauling the same in any required
direction.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I con-
sider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,―
First. The combination with a portable or traction engine of a readily
removeable frame or support attached either to the boiler or to the axles
or framing of the said engine, and carrying a winding drum or drums
driven from the engine, substantially as and for the purposes herein-
before described.
Second. The construction and use of a portable frame or support
specially arranged for ready attachment when required to the boiler or
to the axles or framing of a portable or traction engine, or to any other
suitable motive power engine or machine, and provided with a shaft
carrying a winding drum or drums to be driven from the said engine
or motive power machine, substantially as and for the purpose herein-
before described.
In witness whereof, I, the said George Taylor Yull, have here-
unto set my hand and seal; this Twelfth day of May, in the
year of our Lord One thousand eight hundred and seventy-
