page_text: I, THOMAS DOWNIE, of Caryl Street, Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to winches driven by steam, or other fluid pressure
engines, for hauling, lifting, and lowering, and, particularly, to winches for use
on board ship for working cargo, and for analogous purposes.
It is a practice, more or less common at present, to employ, in connection
with each hatch of a vessel, two winches for loading and unloading, or shifting
the cargo, but owing to the general form and construction of winches, as at
present made, the use of these two winches creates inconvenience on the deck,
and renders the working of them difficult.
The present invention has, mainly, for its object to obviate these difficulties
and defects, and to provide winch machinery, which, while it possesses all the
useful qualities of present winches, affords substantial improvements and advan-
tages; and the machinery according to the invention, consists as follows:-
The winch machinery connected with each hatch of a vessel, consists of two
separate sets of frames, spaced apart, so that one will be at one corner of the
hatch, and the other at the other, side by side, with projecting warping drums at
each side of each frame, and a single cylinder working on a crank; the two
cranks, however, being connected together by a crank shaft. That is, the
crank shaft is common to the two frames, and winches, and the crank pins
being set at the usual or required relation to each other, the turning effort
necessary to work the winches easily is provided.
According to one arrangement, each winch, or portion of the winch, consists
of two vertical frames supporting the crank shaft at the one corner near the
base, and the warping wheel shaft being, say, in the centre above; this shaft
being driven by a pinion on the crank shaft, and a large spur wheel, or by suit-
able double purchase mechanism, with wheels and clutches.
This tooth gearing comes between the two supporting frames, and the warping
wheels are outside them; while the engine cylinder is mounted on the outside
of the outside frame in each part of the winch.
By this construction and arrangement, each winch, or part of the winch,
occupies, relatively, little space as regards width; and a clear space between the
two inner warping wheels is provided. Thus, full facility of working the
winches, and getting about them, is afforded; while, at the same time, they are
light, handy, and inexpensive to make.
If desired, the inner face of the inner warping wheels of the two winches
may be adapted to be connected up by an intermediate length, in the form of a
barrel, say of grooved construction, that is smaller in the centre than at the edges
or flanges, where it is bolted or fastened to the warping wheels.
According to a modification, the two cylinders of the winch are made of

page_text: different diameters, and the steam used first in one, and then in the other, as a
compound engine.

I, THOMAS DOWNIE, of Caryl Street, Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention 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 reference to winches driven by steam or other fluid pressure
engines, for hauling, lifting, and lowering, and, particularly, to winches for use
on board ship for working cargo, and for analogous purposes.
It is a practice, more or less common at present, to employ, in connection
with each hatch of a vessel, two winches for loading and unloading, or shifting
the cargo, but owing to the general form and construction of winches, as at
present made, the use of these two winches creates inconveniences on the deck,
and renders the working of them difficult.
The present invention has, mainly, for its object to obviate these difficulties
and defects, and to provide winch machinery, which, while it possesses all the
useful qualities of present winches, affords substantial improvements and advan-
tages as hereafter specified; and the machinery according to the invention, con-
sists as follows:-
The winch machinery connected with each hatch of a vessel, consists of two
separate sets of frames, spaced apart, so that one will be at one corner of the
hatch, and the other at the other, side by side, with projecting warping drums at
each side of each frame, and a single cylinder working on a crank; the two
cranks, however, being connected together by a crank shaft. That is, the
crank shaft is common to the two frames, and winches; and the crank pins,
being set at the usual or required relation to each other, the turning effort
necessary to work the winches easily is provided.
According to one arrangement, each winch, or portion of the winch consists
of two vertical frames supporting the crank shaft at the one corner near the
base, and the warping wheel shaft being, say, in the centre above. This shaft
being driven by a pinion on the crank shaft, and a large spur wheel, or by other
suitable double purchase mechanism with wheels and clutches.
This tooth gearing comes between the two supporting frames, and the warp
wheels are outside them; while the engine cylinder is mounted on the outside
of the outside frame in each part of the winch.
By this construction and arrangement, each winch, or part of the winch,
occupies, relatively, little space as regards width; and a clear space between the
two inner warping wheels is provided. Thus, full facility of working the
winches, and getting about them, is afforded; while, at the same time, they are
light, handy, and inexpensive to make, and save labour in working them.
If desired, the inner face of the inner warping wheels of the two winches
may be adapted to be connected up by an intermediate length, in the form of a
barrel, say of grooved construction, that is, smaller in the centre that at the edges
or flanges, where it is bolted or fastened to the warping wheels.
According to a modification, the two cylinders of the winch are made of

page_text: different diameters, and the steam used first in one, and then in the other, as a
compound engine.
This invention is illustrated in the annexed drawings, in which Figure 1 is a
plan illustrating the winch machinery; and Figure 2 is a side elevation.
Figure 3 is a diagram illustrating the position of the winch machinery in relation
to the hatchway of a ship.
Referring to the drawings, a are the two sets of winch frames, spaced apart
and arranged respectively at the two corners of the hatchway b of the ship. On
each frame there is a single cylinder c working on a crank d on the shaft e, the
shaft of the two cranks d being connected or continuous, so that the two cylinders
are coupled up and work as one engine. On each side of each of the frames a
there is a projecting whipping drum f, and these drums are driven from the
common crank shaft e through tooth gearings h, the driven wheels of which, and
the drums f, are mounted on the shafts i.
Each frame a consists of simple duplex vertical frames mounted on a bed-
plate, the driven spur wheel h being between them, and the drums f, outside
them; while the cylinder e is secured to the outside frame, and works directly
on the crank; and, as shewn, these engines are adapted to revolve in one direction
only.
Steam is supplied to cylinders c, say from a central position by a valve j, so
that one man works the whole winch machinery of a hatch; and being, run in
one direction, he can also work at one of the whipping drums; and, moreover,
the engines will work with little or no noise. The two cylinders work the
whole apparatus; which provides, as will be seen, four open whipping ends or
drums; and by it a saving of labour for working a hatch is made.
If desired, for hauling, an intermediate barrel may be fitted in between the two
adjacent drums f, as shewn in dotted lines marked ; and the two ends of the
shaft i may be made square at it, over which the bosses of the intermediate piece
may be fitted. Or, the flanges of this piece, and the drums f, may be provided
with holes through which a few fastening bolts may be passed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A winch for the purposes specified, comprising, mainly, two parts spaced
apart, each having an engine, and a projecting whipping drum at each side;
and the driving gear of the two being connected up or adapted to be connected
up together, so as to couple or connect up the power of the whole winch; sub-
stantially as set forth.
2. A winch for the purposes referred to, comprising duplex frames spaced
apar, each having a single cylinder operating the crank thereof, the said cranks
being on the same shaft and coupled together, and driving a tooth gear on each
part, and two whipping barrels or drums projecting over the frame at each end;
substantially as set forth and shewn.
3. A winch of the character herein referred to and as specified in the above
claiming clauses, adapted to receive and operate an intermediate drum between
the two inner adjacent drums f; substantially as set forth.
4. A winch having its parts arranged, constructed and adapted to operate par-
ticularly as shewn in and set forth with reference to the drawings.
