IMPROVEMENTS IN NET AND ROPE HAULING MACHINES
Year: 1885

page_text: I, JAMES MCKIDD, of Thurso Foundry, Thurso, in the county of Caithness,
Engineer and Agricultural Implement Maker, do hereby declare the nature of
my invention for "IMPROVEMENTS IN NET AND ROPE HAULING MACHINES," to be
as follows:-
This invention consists of a new or improved combination or general arrange-
ment, of the parts of a net and rope hauling machine, and of special improvements
in some of the important parts thereof, which will make these machines more
convenient and efficient in their use on board fishing boats for which they are more
particularly intended, than such machines have been as heretofore constructed.
This improved arrangement of net and rope hauling machine and its special
improvement consist all as follows:-Of a vertical plate frame, plain or flat on the
front side, where the ordinary curved (or U) grooved rope hauling pulleys are
mounted on the overhung ends of their shafts passed out through their front or
neck bearings in this frame, which is of the general contour of the driving spur
wheel gearing all carried on their spindles in the said frame, which has a deep
flange all projecting back round its outer edge, so as to enclose and protect all this
wheel gearing. A strong armed frame carrying the back bearings of all the wheel
shafts, is bolted to the back of the deep flange of the front plate frame, which is
formed at the, bottom with a strong bearing flange and inverted deep socket eye
(with opening above for inserting large securing washer and a screw nut) by which
this frame carrying the whole hauling or winding gear is mounted to swivel to any
angle desired upon a strong stem projecting up from a ring bearing basement plate
on which the bottom flange of the frame rests. This circular basement plate is
secured by a number of outer snugs and screw bolts to a main cross beam or beams
of the boat, or other convenient strong part of the boat or deck, and it has a hole
up the centre through which a strong screw bolt is passed preferably from below a
large washer fitted on the underside of the beam or part of the boat to which the
sole plate is secured, and having a large faced washer fitted over the point of the
bolt and the upper face of the socket in the recess of the swivelling frame, where
the screw nut is tightened up properly once for all, so as to allow the frame to
swivel on a vertical axis without unscrewing the nut or allowing it to shake, the
actual fixing in the angled position desired being effected by a pin and pin hole in
the bearing Hange of the frame secured loosely thereto by a chain or otherwise, so

page_text: that it can be raised and inserted at will into any one of a series of holes for the
purpose, formed at short intervals in a circle in the lower fixed basement ring plate,
and just below and corresponding to the radius of the pin and hole from the centre
in the swivelling flange above these holes, all so swivelled and secured at any
desired angle in a new or improved manner. The shafts of the three grooved rope
hauling pulleys would be placed in their frame at about a right angle with the axis
of the centre, one placed as low down as its spur wheel could work in the frame
clear of the recess for securing the central bolt, and all their spur wheels gearing
into each other being of equal size, this would leave room in the centre between the
spur wheels of the two upper side rope pulleys sufficient for an intermediate power-
increasing cross shaft working between them with a pinion on it gearing into the
lower central wheel or one of the side wheels, this shaft having a large wheel the
same size as the others keyed on it behind the pinion; all so that a pinion on
the first motion driving shaft above this wheel and one of the side wheels could
either gear into and drive the one or the other of these wheels by shifting this first
motion shaft on end to the extent of the width. of these wheels apart, and the shaft
could be held in either position by a weighted or spring hinged gab resting on the
shaft between retaining lateral collars. When the pinion on this first motion
driving shaft is pushed into gear with the spur wheel of the side grooved rope
pulley it would drive this direct and at a fast speed, but when the pinion was drawn
into gear with the wheel on the intermediate central shaft to drive.the, rope pulleys
through the pinion on it, the power would be increased in proportion to their
relative size or number of teeth and the speed of winding decreased in the inverse
ratio. To prevent the gearing from running back and enable the machine to hold
all the rope or net drawn in, a double armed pawl would be mounted to oscillate on
a centre in the web or flange over the pinion of the first motion shaft, having a
small weighted lever over it, which when tilted to one side or the other would press
the pawl arm into the teeth of pinion to hold it in either direction. from turning
back through allowing it to turn. forwards in hauling in. In hauling in nets by
their "head backs" or. ropes, or the ropes of, hauling nets or other lines, they are
passed over the upper groove pulley, on one side and turning in down to and under
the lower central grooved pulley and up to and over the other side grooved pulley
down into the boat, the net and its corks passing uninjured in front of the sinooth
face of these rope. pulleys. This first motion shaft would preferably be fitted with
a.fly wheel on it at the inside of the frame to give steady notion and be driven by
a handle inserted into the fly wheel, and for giving greater power, the ends of this
first motion shaft projects beyond the front side of the frame to allow a winch
handle to be secured on it when desired.

I, JAMES MºKIDD of Thurso Foundry, Thurso, in the county of Caithness,
Engineer and Agricultural Implement Maker, 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 in writing, reference
being had to the accompanying Sheet of Drawings and to the reference letters and
figures marked thereon, that is to say :-
My invention consists of a new or improved combination or general arrange-
ment of the parts of a net and rope hauling machine, and of special improvements
in some of the important parts thereof, which will make these machines, constructed
in accordance with my improvements, more convenient and efficient in their use on
board fishing boats, (for which they are more particularly intended), than such
machines have been as heretofore, constructed.
And in order that, the nature and novelty of my said invention and mode of
performing or putting the same into effect or practice, may be properly understood,
I will now proceed to describe the several figures on the Sheet of Drawings I have
hereunto appended for that purpose; the same letters of reference indicating the
same parts in the several figures where shown.
Figure 1, is a front elevation, Figure 2 a side elevation partly in section
through the case frame, to show the enclosed wheel gearing, and Figure 3 is a
back elevation, both corresponding to Figure 1, of a net and rope hauling machine
constructed in accordance with my said invention or improvements; while
Figure 4 is a detailed plan or face view of the carrying foot-step face plate B, B¹,
on which the whole machine swivels, and which is secured by separate bolts to the
beam or deck of the boat at 2.
Referring to these figures;, my said improved arrangement of net and rope
hauling machine and its special improvements, consist of a vertical plate frame A
with outside rim web A¹ enclosing the driving wheel gearing. This frame is flat
on the front vertical plate side A where the ordinary curved (or U) grooved
rope hauling pulleys a, a, a³, are mounted on the front over-hung ends of their
three spindles or shafts b, b1, b2; passed out for that purpose through their front or
neck bearings c formed in this frame A. The frame A is of the general contour of
the driving spur wheel gearing, which is carried on their spindles within the
frame A, and its deep flange A¹ projecting back all round its outer edge, so as to
enclose and protect the wheel gearing. A strong feather armed frame A*, formed with
the back bearings c¹ of all the wheel shafts b, 61, 62, is bolted to the back of the
deep flange A¹ of the front plate frame A. The frame A, A¹, is formed at the
bottom with a strong bearing flange A, and inverted deep socket eye. A³, with
opening All above for inserting large securing washer Bil and. a screw nut,
by which this frame A, A1, A2, A³, carrying the whole hauling or winding gear, is
mounted to swivel vertically to any horizontal or radial angle desired, upon a
strong stem B projecting up from a foot-step bearing ring or basement plate B¹, on
which the bottom flange A1, A3 of the frame A, A¹, rests. This circular foot-step
or basement plate B, B¹, is secured by a number of outer snugs and screw bolts

page_text: at Bч, to a main cross beam or frame of, or secured to, the beams of the boat, or
other convenient strong part or frame of the boat or deck. A hole is formed in the
centre of the whole, up through which a strong screw bolt B2 is passed, preferably
from below, with a large washer B₁11 fitted on the under side of the beam or part 2
of the boat, to which the sole plate B, B¹ is secured; and having a large faced
washer B³ fitted over the point of the bolt and the upper face of the socket A³ in
the recess A", of the swivelling frame A, A', where the screw nut B is properly.
tightened up to the foot-step plate B, B¹, (once for all in its proper place), so as to
allow the frame A, A³, to swivel on a vertical axis without unscrewing the nut B',
or allowing it to shake at this swivelling joint. The actual fixing of the frame in
the angled position desired, is effected by a pin P, carried loosely by a chain or
otherwise to the frame, within a pin hole in the bearing flange A³, A¹¹, of the
frame, so that it can be raised and inserted at will into any of a series of holes p
for the purpose, formed at short intervals apart in a circle in the lower fixed
'basement ring plate B, B¹ and just below and corresponding to the radius of the
pin P, and its hole or holes formed in the swivelling flange above these holes p; all
so that the whole frame A, A1, A2, and its hauling gearing and mechanism are thus
swivelled and secured at any desired angle in this new manner by my improve-
ments. The shafts b, b¹, b³ of the three grooved friction gripping and hauling
rope pulleys a, a¹, a², which are all of equal size, would be placed in their bearings
c, c', in the frame A, A1, A2 preferably about a right angle with the axis of the
centre one a placed as low down as its spur wheel could work in the frame A, A¹
clear of the recess A¹¹ for securing the central bolt B. The spur wheels C, C¹, C³,
are all of equal size, and are keyed on the spindles b, 61, 6% of their respective
pulleys a, a, a, which they drive, so as to gear into each other all in the same
plane close up to the inside of the plate frame A. This arrangement leaves room
in the centre over the wheel C, between the spur wheels C¹, C (of the two upper
side rope pulleys a³ a³) sufficient for an intermediate power-increasing cross
shaft b working in bearings clll, in the frame A, A³, with a pinion C on it
gearing preferably into the side wheel C2, (but it may be into the central wheels C)
this shaft 6 having a large wheel C, keyed on it, the same size as the wheels
C, C, C², behind the pinion Cl; all so that a pinion C³ on the first motion or
driving crank handle shaft 63, above this wheel C, and one of the side wheels C¹,
could either gear into this latter wheel C₁ as shown in this position in the
Drawings to actuate the hauling pulleys a, a', a², on their first direct quick motion
shaft b', or by shifting the winch handle shaft 63, back on end to the extent of the
width of these wheels apart, to put the pinion C³ on it into gear with the
wheel C, on its second motion shaft 6", so as to actuate the pulleys a, a, a², by
the second speed and power increasing wheels C", Cl, before described, in pro-
portion to the size and number of, teeth in these wheels. The shaft b³ could be
held in either position by a weighted or spring hinged gab G resting on the shaft
between retaining lateral collars. When the pinion C³ on this first motion driving
shaft is pushed into gear with the spur wheel C₁of the side grooved rope
pulley a¹, it would drive this and the other pulleys a, a², direct and at a fast
speed; but when the pinion was drawn into gear with the wheel C¹¹ on the
intermediate central shaft 6", to drive the rope pulleys through the pinion on it,
the power would be increased in proportion to their relative size or number of
teeth and the speed of winding decreased in the inverse ratio as stated. To
prevent the gearing from running, back and enable the machine to hold all the
rope or net drawn in, a double armed pawl H, H¹, would be mounted to oscillate
on a centre h, in the web or flange over the pinion C³ of the first motion shaft 6³,
having a small weighted lever h¹ fulcrummed over it, which when tilted to one
side or the other would press the pawl arin H into the teeth of pinion C³, to hold
it in either direction from turning back although allowing it to turn freely forward
in bauling-in. In hauling in nets by their "head-backs" or ropes, or the ropes of
hauling nets or other lines, they are passed over the upper groove pulley a¹, on one
side and carried down to and under the lower central grooved pulley a, and up to

page_text: and over the other side grooved pulley a³, down into the boat all as indicated by
the arrows, or it might be in the opposite direction when this was found necessary;
the net and its corks passing uninjured in front of the smooth face of these rope
pulleys a, a, a. This first motion shaft b would preferably be fitted with a fly
wheel I on it at the inside A2 of the frame to give steady motion and be driven by
a handle I' inserted into the fly wheel; and for giving greater power, the end of
this first motion shaft b³, projects beyond the front side A of the frame and may
have a handle fitted on it also when desired. Guide rollers J, J¹, would preferably
be fitted on spindles in anugs at j at the front side edges of the frame projecting
sufficiently beyond these to lead the "head back" rope of the net to and from the
upper hauling pulleys a¹, a², all clear of the front face A of the frame.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The general construction, or arrangement and combination of the parts of a
net, or rope hauling machine, substantially as herein described, and shown in the
accompanying Drawings.
2. The swivelling and securing of the main frame, carrying all the actuating
gearing of a net or rope hauling machine, by a flanged socket A A at bottom, on a
