IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF WINDING GEAR OR APPARATUS FOR HAULING, LIFTING, AND WINDING
Year: 1873

page_text: LETTERS PATENT to George Leach, of Leeds, in the County of York,
Engineer, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
AND ARRANGEMENT OF WINDING GEAR OR APPARATUS FOR HAULING, LIFTING,
AND WINDING.”
Sealed the 3rd June 1878, and dated the 7th April 1873.
PROVISIONAL SPECIFICATION left by the said George Leach at
the Office of the Commissioners of Patents, with his Petition, on
7th April 1873.
I, GEORGE LEACH, of Leeds, in the County of York, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION AND ARRANGEMENT OF WINDING GEAR OR APPARATUS FOR HAULING,
LIFTING, AND WINDING," to be as follows:
-
The object of my Invention is so to construct and arrange the various
parts of the winding gear that the whole of the mechanism including
the engine and boiler for working the same may be rendered as compact
as possible and brought into the smallest possible compass, and therefore

page_text: be more particularly applicable for use on board ship where it is of
importance to economize room.
In carrying out my Invention I make use of a long cylindrical boiler
which I place in a vertical position, the fire-box and ash-pit being at
the lower end. The engine and its accessories are mounted on the side
of the boiler which also carries the bearings for the gearing, whereby
the hauling gear is actuated.
In small vessels such as fishing smacks for which my improvements
are particularly applicable the upper part of the boiler projects up
through the deck, and is provided round its upper edge with a circular 1
rail or guide made of angle iron which supports the barrel of a capstan.
This capstan forms a kind of cup or cover for the upper end of the
boiler, and is provided inside with three or more antifriction wheels
which run on the circular rail or guide on the top of the boiler, and thus
prevent undue friction. To the lower edge of the capstan barrel is 1
adapted a large horizontal guide wheel with a V edge which runs against
three or more V shaped guide wheels mounted in bearings secured
to the deck. The capstan barrel also carries a large toothed wheel
which is driven by a pinion on the upper end of a vertical shaft
mounted in bearings attached to the side of the boiler. The large :
toothed wheel and the large horizontal guide wheel are formed of one
casting, and are attached by a band break connection to the capstan
barrel so as to allow them to yield and the rope to surge should any
undue strain be put thereon. The long vertical shaft which carries the
pinion whereby the capstan is actuated is driven by the engine by :
means of suitable bevil gearing. The flue or chimney from the fire-
box passes up the middle of the boiler and out at the top of the capstan
barrel; there is therefore no space lost, and the whole apparatus may be
lowered through a hole (cut in the deck) on to a foundation prepared in
the hold or bottom of the vessel for the purpose. A hauling, lifting, or
winding apparatus constructed on this plan will be found very useful
in warehouses or on wharves or other places where there is rapid working
and light work.

filed by the said George Leach in the Great Seal Patent Office
on the 7th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LEACH, of Leeds, in the County of York, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Leach, Her special licence that I,
the said George Leach, my executors, administrators, and assigns, or
such others as I, the said George Leach, 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 THE CONSTRUCTION AND
ARRANGEMENT OF WINDING GEAR OR APPARATUS FOR HAULING, LIFTING, AND
WINDING," upon the condition (amongst others), that I, the said George
Leach, 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 Leach, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to
say) :—
The object of the present improvements is so to construct and arrange
the various parts of the winding gear that the whole of the mechanism
including the engine and boiler for working the same may be rendered
as compact as possible and brought into the smallest possible compass,
and therefore be rendered more particularly applicable for use on board
ships when and where it is of importance to economize room.

page_text: In the accompanying Drawings I have shewn my improvements as
adapted for a fishing vessel.
Fig. 1, Shoet I., is a plan representing the stern part of the vessel,
and shewing the propellor and shaft which is driven by the engine A.
The boiler B is a vertical one with a central fire-place and flue, and 5
its upper part is enclosed within the capstan as seen best at Fig. 2,
Sheet II., which is a vertical section through the capstan and boiler.
Fig. 3 is a plan view of the capstan head with the covering plate
removed so as to shew some of the working parts.
Figures 4 and 5, Sheet III., are elevations of the capstan boiler and 1
engine complete; Fig. 6 is a sectional plan view of the capstan; and
Fig. 7 is a similar view of the boiler.
Fig. 8 is a detached view of the break which will be hercafter more
particularly referred to.
In carrying out my present improvements I make use of a long 1
cylindrical boiler B, B, B, Fig. 2, which I place in a vertical position;
the fire-box and ash-pit 6 being at the lower end. The engine A and its
accessories are mounted on the side of the boiler as seen at Figures 4, 5,
and 7. The boiler also carries the bearings c, c, for the gearing, whereby
the hauling gear is actuated.

In small vessels such as fishing smacks (for which my improvements
are particularly applicable), the upper part of the boiler projects up
through the deck O, as shewn at Fig. 2, and is provided round the upper
edge with a circular rail or guide d made of angle iron which supports
the barrel e of a capstan; this capstan forms a kind of cap or cover for 2
the upper end of the boiler B, and is provided inside with three or more
antifriction wheels ƒ, f, which run on the circular rail or guide on the
top of the boiler as indicated by the dotted lines in the plan view Fig. 3,
and thus prevent undue friction. To the lower edge of the capstan
barrel is adapted a large horizontal guide wheel 9 with a V edge which 8
runs against three or more V shaped guide wheels g¹, g', mounted in
bearings secured to the deck. The capstan barrel e also carries a large
toothed wheel h which is driven by a pinion on the upper end of a
vertical shaft ¹ mounted in the bearings c³, c³, attached to the side of the
boiler. The large toothed wheel and the large horizontal guide 3
wheel gare formed of one casting which is provided with a ring or
flange e¹ around which passes a break band connection j, one end of

page_text: which is secured to a pin fitted in the shell e of the capstan, as shewn at
Fig. 8, and the other end is connected to the cranked end of the vertical
rod k, as shewn at Fig. 2, the upper end of which carries a toothed
sector ¹, Fig. 3, into which gears the worm 7, so that when the latter is
rotated by means of a winch as indicated in Fig. 3 the rod k will be
rotated, and will cause the band of the break j to bear tightly on the
ring e¹ and create the desired amount of friction, and cause the capstan e
to be carried round with the wheel g. This arrangement will allow the
capstan to yield and the rope to surge should any undue strain be put
thereon. The long vertical shaft which carries the pinion i (whereby
the capstan e is actuated) is driven by the engine A by means of
suitable bevil gearing, as shewn in Figures 2, 4, and 5. The flue or
chimney 6* from the fire-box passes up the middle of the boiler and out
at the top of the capstan barrel, therefore there is no space lost, and the
whole apparatus may be lowered through a hole (cut in the deck) on to
a foundation prepared in the hold or bottom of the vessel for the
purpose. A hauling, lifting, or winding apparatus constructed on this
plan will be found very useful in warehouses or on wharfs, or other
places where there is rapid working and light work. The plan view,
Fig. 1, represents the manner of adapting the engine boiler and gearing
for actuating a stern screw propeller.
Having now described my Invention of "Improvements in the Con-
struction and Arrangement of Winding Gear or Apparatus for Hauling,
Lifting, and Winding," and having explained the manner of carrying
the same into effect, I claim as the Invention secured to me by Letters
Patent as aforesaid, the mode herein set forth of constructing, arranging,
and combining the driving gear, the boiler, and the capstan or winding
gear; I also claim mounting the hollow capstan on the upper end of the
boiler so as to enclose the same and economize space, as herein set forth.
In witness whereof, I, the said George Leach, have hereunto set
my hand and seal, this Seventh day of October, in the year of
our Lord One thousand eight hundred and seventy-thron
