The object of my said invention is to provide an improved form of apparatus, to
be used on board fishing boats, for hauling in nets, raising masts, hoisting sails,
raising anchors, and other analogous operations, in a better and safer manner than
has hitherto been accomplished.
One modification of my invention, consists of three horizontal sheaves disposed
in a triangle, the centre sheave forming its apex and being farthest from the
central spindle or standard of the machine. The main sole plate of the machine is
of cast iron, and is provided with two rollers for facilitating the shifting of the
machine (on a wooden gantry or shears fixed to the boats deck), to port or star-
board, as the hauling of the net may require. This sole plate has attached to it a
malleable iron spindle projecting downwards through the wooden shears having a
nut and large washer for fixing the machine into the required position after being
shifted.
•
On this centre malleable spindle, and resting on the sole plate, is fitted a cast
Iron socket or sleeve, to which is attached the framing carrying the spur wheel
gearing, and the hauling sheaves. This socket or sleeve is free to revolve round
the centre spindle, to haul the nets in a straight line from either quarter, and is
kept in position by two pins placed into corresponding notches in the sole plate
and flange of the socket. The sockets for the sheave spindles are bushed with
white metal as a preventive against rust when the machine is exposed to the action
of salt water.
On the centre spindle, and immediately above the net-hauling machinery, is placed
the friction pulley and strap with the differential gearing attached. The object
of this part of the machine is to enable the Fishermen to have complete control of

page_text: the hauling of the nets in a rough sea, when the Boat is pitching. By means of a
small lever attached to the friction strap, the nets can be instantaneously let go,
thus preventing any sudden or undue strain being brought on the head-back, which
endangers the loss of the nets.
By means of this arrangement the extra strain has no tendancy to force the
winch handle out of the mens hands, which is a frequent cause of broken arms
with the machines hitherto in use.
The lower sleeve and the upper capstan can be made to revolve simultaneously,
or not, as desired, by means of internal bevel gearing placed between the two, and
by the use of the friction strap before mentioned.
On the centre spindle, and above the mechanism just described, is placed the
capstan, which can be used independently of the net hauling apparatus and is for
the purpose of providing a purchase to enable the mast to be set up quickly by
two or three men. It can be used also for hoisting up the sail, raising the anchor,
and a variety of other work, on the top of this capstan, and forming part of it,
are two bevel toothed wheels, of different diameters, into these are geared two
pinions also of different diameters, carried in a top frame. The fly wheel centre is
fitted with a sleeve having keyed thereon the small bevel pinion, working into the
largest horizontal bevel wheel, and forming a slow and powerful motion; through
this centre socket the sharft passes with the large bevel pinion, working into the
small horizontal bevel wheel forming the quick speed. Both the horizontal bevel
wheels are in one casting Only one crank handle is used, by shifting which
from the wheel to the shaft, either the fast or slow speed can be used, as
required.
t:
The top frame with its fly-wheel, shafts and pinions attached can also be shifted
and fixed for work at any part of the circumference of the wheels, thereby placing
the winch handle in the best position, for working the capstan, or hauling the nets.
This top frame is kept in position by means of a screwed nut and lever attached
The whole machine is so arranged that it can be taken to pieces at any time for
inspection or preservation when the boats are laid up for the winter, by simply
unscrewing two nuts.
The above description refers to a vertical machine
Another modification of the machine is the adoption of the horizontal
arrangement with vertical net hauling sheares, which arrangement is sometimes
preferred.
And in order that this arrangement may not interfere with the free use of the
capstan, the framing carrying the hauling sheaves and gearing attached is hinged
and arranged to be folded down out of the way, by pulling out a malleable fixing
pin. A catch or pawl is applied at the bottom of the capstan in both modifications,
and by putting it into play the whole machine can be turned round on its
own axis to any required angle or position for hauling by means of the Crank
handle.
The toothed wheels attached to the pullies or sheaves are fenced all round to
prevent injury to the nets.
When hauling in nets, the ropes are passed partially round each sheave
successively; but when heavier haulage is required the rope is passed several times
round the capstan,

NET HAULING MACHINE AND BOAT'S CAPSTAN
"A COMBINED
The object of my said Invention is to provide an improved form of apparatus to
be used on board fishing boats, for hauling in nets, raising masts, hoisting sails,
raising anchors, and other analogous operations, in á better and safer manner than
has hitherto been accomplished.
One modification of my invention consists of three horizontal sheaves disposed
in a triangle the centre sheave forming its apex and being farthest from the central
spindle or standard of the machine. The main sole plate of the machine is of cast
iron, and is provided with two rollers for facilitating the shifting of the machine
(on a wooden gantry or shears fixed to the boats deck) to port or starboard as the
hauling of the net may require. This sole plate has attached to it a malleable
iron spindle projecting downwards through the wooden shears, having a nut
and large washer for fixing the machine into the required position after being
shifted.
On this centre malleable spindle and resting on the sole plate is fitted a cast
iron socket or sleeve to. which is attached the framing carrying the spur-wheel
gearing and the hauling sheaves This socket or sleeve is free: to revolve round
the centre spindle, to haul the net in a straight line from either quarter and is
kept in position by two pins placed into corresponding notches in the sole plate
and flange of the socket. The sockets for the sheave. spindles are bushed with
white metal as a preventive against rust when the machine is exposed to the
action of salt water
On the centre spindle and immediately above the net hauling machinery, is
placed the friction pulley and strap with the differential gearing attached. The
object of this part of the machine is to enable the Fishermen to have complete
control of the hauling of the nets in a rough sea when the Boat is pitching. By.
means of a small lever attached to the fricture strap the nets:can be instantaneously

two or three men. It can be used also for hoisting up the sail, raising the anchor.
and a variety of other work On the top of this capstan; and forming part of it,
are two bevel toothed wheels of different diameters, into these are geared two
pinions also of different diameters carried in a Top frame. The fly wheel centre is.
fitted with a sleeve having keyed thereon the small bevel pinion, working into the
Jargest horizontal bevel wheel, and forming a slow and powerful motion; through
this centre socket the shaft passes with the large Bevel pinion working into the

And in order that my said Invention may be clearly understood reference is
hereby made to the accompanying drawings in which similar letters of reference
indicate corresponding parts in the several figures.
Fig: 1 is a sectional elevation of one form of my invention with vertical
sheaves on horizontal axles. Fig: 2 is an elevation of the same, facing the
sheaves, and Fig: 3 is an elevation of the same in a similar position to that
shewn in Fig: 1.

Although I have shewn in the drawings my combined net hauling machine
and capstan with vertical sheaves, it is obvious that, with slight modifications
the sheaves may be arranged horizontally with the same amount of handiness and
adaptability
Having thus particularly described and ascertained the nature of my said
Invention and the manner in which the same is to be performed, I claim
1. The combination of the net hauler and capstan with the hauling sheaves
arranged either horizontally or vertically substantially as hereinbefore described
and shewn on the drawings

page_text: 2. In the above mentioned combination the means and arrangements for folding
down or lowering the vertical sheaves out of the way when the Capstan is being
used substantially as hereinbefore described and shewn on the drawings
