Year: 1876

page_text: LETTERS PATENT to James Duthie, of the City and County of Aberdeen, North
Britain, for the Invention of "AN IMPROVED ARRANGEMENT OF WINDLASS OR
PAYING-OUT AND HAULING-IN GEARING FOR USE ON BOARD OF FISHING AND
OTHER BOATS"
Sealed the 16th February 1877, and dated the 23rd September 1876.
PROVISIONAL SPECIFICATION left by the said James Duthie at the Office
of the Commissioners of Patents on the 23rd September 1876.
JAMES DUTHIE, of the City and County of Aberdeen, North Britain.
" AN
IMPROVED ARRANGEMENT OF WINDLASS OR PAYING-OUT AND HAULING-IN GEARING
FOR USE ON BOARD OF FISHING AND OTHER BOATS."
This said Invention has for its object the more safe and easy heaving-in or
paying-out of nets and lines or ropes on board of fishing and other boats than here-
tofore, and which in rough or stormy weather will be most valuable and save the
loss and waste of nets and other tackle.
And the nature of this new or improved winding machine or mechanism consists
of a strong swivelling or revolving iron or wood post or shaft set and revolving
vertically or at an angle over and within the boat with its lower end in a footstep
bearing, and in a ring or bush bearing some distance above this, as at the deck,
or a cross beain below this, with the upper part projecting high enough above the
upper bearing to carry the two cross spindles (through it in bearings) of the large
spur wheel and over each other close to one side of the post with a V grooved pulley
on each, a little smaller than the wheels, or they might be fixed on their respective
spindles, all so that the cord, line, or rope or strong edge rope of the net would pass
over the top and inside of the upper grooved pulley, crossing between the two and
round the front and lower side of the under grooved pulley to or from the inside of
the boat, the pulleys being overhung at the end of their spindles and made with
grooves widest at the outside and converging inwards in a curvilinear or shape
to gripe the various sized ropes or cords better, and having the winch or winding
handle on the opposite end of the top spindle to that of the grooved pulleys, so as
to turn them both through their geared spur wheels, and so wind in or pay out the
cord or cord and net passing over and through the grooved pulleys, as stated. And

page_text: when greater power is desired another spinde might be similarly mounted through
the upper part of the swivelling post with a small pinion on its one end gearing
into the wheel of the upper grooved pulley, when the winch handle would be fixed
on the other end of this spindle, which would thus give a greater power in proportion
to the difference in size of the wheel and pinion. A stud with a loose holding pawl
is fixed to the swivelling post a little above the ring bearing, so that the pawl
works into a notched ring secured to the beam or floor above the bush bearing
in a similar manner to an ordinary capstan, which thus steadies the post in any
position to which it may be turned and sustains the strain in winding.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Dutbie in the Great Seal Patent Office on the 22nd March
1877.
"AN
JAMES DUTHIE, of the City and County of Aberdeen, North Britain.
IMPROVED ARRANGEMENT OF WINDLASS OR PAYING-OUT AND HAULING-IN GEARING
FOR USE ON BOARD OF FISHING AND OTHER BOATS."
My said Invention has for its object the more safe and easy heaving-in or paying-
out of nets and lines or ropes on board of fishing and other boats than heretofore,
and which in rough or stormy weather will be most valuable and save the loss and
waste of nets and other tackle.
And in order that the nature, novelty, and mode of performing my said Invention
may be fully understood I shall now proceed to describe the best mode and means I
am at present aware of for putting the same into effect or practice, reference_being
had to the two Figures on the accompanying Sheet of Drawings which I have
hereunto appended for that purpose, the same reference letters indicating the same
or like parts in both Figures where shown.
Figure 1 is a front elevation and Figure 2 a side elevation of one modification or
arrangement of my new or improved windlass or gearing for hauling or paying-out
nets, ropes, or other tackle, on board of fishing or other boats or vessels, as detached
from the boat or vessel, and constructed in accordance with and illustrative of my
aid Invention.
Referring to these Figures the nature of this new or improved winding machine
or mechanism consists of a strong swivelling or revolving solid or hollow iron or
wood post or pillar A set and revolving vertically (or it might be at an angle) over
and within the boat, with its lower end formed as a journal pivot A' working in a
supporting footstep bearing secured at any convenient part of the boat, steadied
and revolving in a ring or bush bearing B secured some considerable distance above
this, as at the deck, or to a cross beam B¹ either above or below the deck with the
upper part of the pillar A projecting high enough above the upper bearing B to
carry the two cross spindles c, d, of the large spur wheels C, D, over each other
close to the one side of the post A, with a V grooved pulley C, D, on each a little
smaller than the wheels C, D, and preferably cast in one piece and fixed on their
respective spindles c, d, revolving in bearings through the swivelling pillar A, all so
that the cord, line, or rope, or strong edge rope E of the net F would pass over the
top and inside of the upper grooved pulley D', crossing between the two and round
the front and lower side of the under grooved pulley C¹ to or from the inside of the
boat, the pulleys C¹, D¹, being overhung at the end of their spindles c, d, and made
with grooves widest at the outside and converging inwards in a curvilinear or
V shape to gripe the various sized ropes or cords better, and having the winch or
winding handle g¹ on the opposite end of the top spindle g to that of the pinion G
which works into and turns the geared spur wheels D, C, of the grooved pulley C¹, D¹,
and so winds in or pays out the cord or cord and net passing over and through the
grooved pulleys, as stated. And when greater power is desired the handle g¹ is

page_text: placed on the opposite end of its spindle g and another handle g" fitted on the end
of the spindle d of the wheel D, both as seen dotted in Figure 2, so that two
persons could be winding at the same time on opposite sides; but for fine weather
the handle g fitted on the end of the spindle d of the wheel D is found sufficiently
powerful for ordinary purposes, and when it only is used the upper handle gl,
spindle g, and pinion G, may be unshipped from the post, ready for being replaced
at any time required. A snug with a loose holding pawl H is fixed to the swivelling
post A a little above the ring bearing B, so that the attendant may by his hand or
foot set the pawl H in any of the notches in the upper outer edge of the bearing
ring B secured to the beam or floor B¹, which thus steadies or secures the post A in
any position to which it may be turned, and sustains the strain in winding in a
similar manner to an ordinary capstan.
A ratchet wheel I is shown fixed on the back end of the spindle d, into which a
loose pawl i hanging from the spindle g takes, so as to prevent the unwinding of
the gearing and grooved pulleys C, C¹, D, D¹, when the attendant lets go the
winding handle g¹.
Figure 1A shows a sectional elevation of a slightly different modification of the
footstep bearing of the swivelling pillar A from that shown in Figures 1 and 2,
consisting of a fixed pivot A¹ secured to the low part of the boat, on or over which
a hollow journal or bearing in the lower end of the pillar A works.
Having now described the nature of my said Invention and the manner of
performing the same, I have to state that I do not confine myself to the precise
details herein described or delineated, but what I consider novel and original,
and therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is,-
First. The general construction and arrangement of windlass or hauling-in and
paying-out gearing with duplex wheels C, D, and pulleys C¹, D¹, on a swivelling
post A for use on board of fishing or other vessels, all substantially as herein
described in reference to and shown in the accompanying Drawings.
Second. The construction or arrangement and use of a notched holding ring h
and pawl H for holding in any desired position the swivelling pillar or post A of
windlasses for hauling-in or paying-out nets or ropes on board of fishing or other
boats, substantially as herein described in reference to and shown in the accompany-
ing Drawings.
In witness whereof, I, the said James Duthie, have hereunto set my hand
and seal, this Sixteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-seven.
JAMES DUTHIE. (LS.)
