IMPROVE- MENTS IN OR CONNECTED WITH WINDLASSES OR SHIPS' WINDING APPARATUS:
Year: 1875

page_text: LETTERS PATENT to Andrew Paul, of Dumbarton, in the County of
Dumbarton, North Britain, Engineer, for the Invention of "IMPROVE-
MENTS IN OR CONNECTED WITH WINDLASSES OR SHIPS' WINDING APPARATUS:"
Sealed the 5th November 1875, and dated the 14th May 1875.
PROVISIONAL SPECIFICATION left by the said Andrew Paul at thè
Office of the Commissioners of Patents, with his Petition, on the
14th May 1875.
I, ANDREW PAUL, of Dumbarton, in the County of Dumbarton,
North Britain, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN OR CONNECTED WITH WINDLASSES OR SHIPS'
WINDING APPARATUS," to be as follows, that is to say :—
This Invention relates to ships' winding apparatus of the kind
described in the Specification of Letters Patent granted to Matthew
Paul, and dated 2 May 1862 (No. 1301); and the present improvements
have principally for their object to arrange and combine the parts in a
better manner so as to occupy or require less space whilst being more
'convenient in use.

page_text: By the present Invention instead of placing a capstan or capstan
shaft in front of the worm shaft there is substituted a horizontal counter
shaft at the rear of the machine, the side frames being extended back-
wards to support such countershaft. The ends of the countershaft
overhang beyond the side frames and have winding barrels fixed on
them, and the countershaft is geared to the windlass shaft by preference
by means of two pairs of spur wheels of which those on the counter-
shaft are smaller. These wheels on the countershaft are formed with side
rims to which travellers or frictional grippers are fitted, these travellers
being arranged in connection with hand levers so that the countershaft,
and through it the windlass shaft, can be worked by hand. The worm
on the vertical shaft is made movable on that shaft, and when the
windlass shaft is worked by hand the teeth of the worm wheel lift up
the worm and it can be secured by a key or otherwise out of gear so as
to disconnect the engine details from the windlass.
With the improved arrangements herein-before described an increase
of leverage is obtained by means of the countershaft when working the
windlass by hand; and on the other hand when working by steam the
countershaft receives a very suitable speed for warping purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Andrew Paul in the Great Seal Patent Office
on the 12th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
PAUL, of Dumbarton, in the County of Dumbarton, North Britain,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Andrew Paul, Her special licence, that
I, the said Andrew Paul, my executors, administrators, and assigns, or
such others as I, the said Andrew Paul, 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,

page_text: 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 OR CONNECTED WITH
WINDLASSES OR SHIPS' WINDING APPARATUS," upon the condition (amongst
others) that I, the said Andrew Paul, 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 Andrew Paul, 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 in writing, reference being had to the accompanying
Drawings, that is to say :-
My said Invention relates to ships' winding apparatus of the kind
'described in the Specification of Letters Patent granted to Matthew
Paul, and dated 2 May 1862 (No. 1301); and my present improve-
ments have principally for their object to arrange and combine the parts
in a better manner so as to occupy or require less space whilst being
more convenient in use.
By my present Invention instead of placing a capstan or capstan shaft
in front of the worm shaft there is substituted a horizontal countershaft
at the rear of the machine, which shaft has winding barrels fixed on its
overhanging ends and is geared to the windlass shaft so as to rotate at a
somewhat greater speed. The added countershaft is also arranged to be
worked by hand levers, so that an increase of leverage is obtained when
working the windlass through it by hand; whilst on the other hand
when working by steam the countershaft receives a very suitable speed
for warping purposes.
And in order that my said Invention and the manner of performing
the same may be properly understood, I hereunto append two Sheets
of explanatory Drawings to be herein-after referred to, and representing
the ship's winding apparatus as made with my improvements. In these
Drawings the same reference numerals are used to mark the same or
like parts wherever they are repeated.

page_text: Figure 1 on Sheet 1 of the Drawings is a sectional plan, and Figure 2
is a sectional side elevation; whilst Figures 3 and 4 on Sheet 2 are a
longitudinal vertical section and a sectional front elevation respectively.
The parts are carried upon a wrought-iron bed plate 5 and between
two strong parallel cast-iron side frames 6, bolted down to the bed
plate 5; at the forward part of the machine a transverse horizontal
crank shaft 7 driven by steam cylinders 8 which are attached to the side
frames 6 gives motion through one or other of a pair of bevil pinions 9
fitted with engaging and disengaging clutches to a bevil wheel 10 on
the upper end of the worm shaft 11; this shaft which is carried in a
footstep bearing in a casting 12 bolted to the bed plate 5 and to the side
frames 6, and is held by an upper collar bearing in a transverse wrought-
iron frame bar 13 bolted to the side frames, has on it a worm 14 which
is in gear with a worm wheel 15 fast on the windlass shaft 16 between
the two chain barrels or pulleys 17; the windlass shaft 16 is carried in
bearings in the side frames 6, being provided with the usual frictional
brakes and ratchet and pawl holding gear, and it has also fast on it or
formed on the inner cheeks of the chain pulleys 17 two spur wheels 18,
with which there are in gear two smaller spur wheels 19 fast on a
countershaft 20 carried in bearings at the after ends of the side frames 6 ;
this countershaft 20 has winding barrels 21 fixed on its ends which
overhang outside the side frames 6; the spur wheels 19 on the counter-
shaft 20 are formed with side rims 22 to which travellers or frictional
grippers 23 are fitted, each gripper consisting of a pair of plates which
are formed with flanges to catch on the insides of the wheel rims, and
which have connected or hinged to them a lever 24 formed with an
eccentric boss which bears on the outside of the wheel rims; each
gripper lever 24 is connected by a link 25 to one arm of a double
armed hand lever 26 carried by a pedestal 27 bolted to the deck, and
when either gripper lever 24 is raised its eccentric boss causes the wheel
rims 22 to be gripped and the wheel 19 is turned round a little in
consequence, but when the gripper lever 24 returns downwards the
gripper plates become relaxed and slip down without turning the wheel
back; which actions are well known in connection with such con-
trivances; the joint pin of the gripper lever 24 and gripper plates 23 is
made with its middle and end parts eccentric to each other, and when
the apparatus is worked by steam the pin is turned half round, which
prevents the gripping action from taking effect or interfering with the.

page_text: movement of the shaft 21 in either direction. The worm 14 'on the
vertical shaft 11 is held between a collar on the shaft and a key 28
passed above it through the shaft when the windlass-is being worked by
steam; but when the windlass is to be worked by hand through the
countershaft 20 the key 28 is removed and the action of the worm
wheel 15 then lifts up the worm 14, which on reaching its highest
position may be secured there by passing the key below it through the
shaft 11. Tho worm 14 is fitted to the shaft 11 with a groove and
feather so as to be turned thereby.
In some cases the steam cylinders and parts through which they drive
the windlass may be omitted, the remaining combination then forming a
powerful and convenient hand windlass; whilst if there is a steam
winch on board the ship a chain pulley may be fixed on the counter-
shaft 20 to receive an endless driving chain from the winch.
Having thus particularly described my said Invention and the manner
of performing the same, I have to state that I do not restrict
myself to the precise details herein described or delineated, but that
what I believe to be novel and original, and claim as the Inven-
tion secured to me by the herein-before in part recited Letters Patent
is, the arranging and combining of the countershaft (20) with the other
parts, substantially as and for the purposes herein-before described.
In witness whereof, I, the said Andrew Paul, have hereunto set
my hand and seal, this Tenth day of November, in the year
of our Lord One thousand eight hundred and seventy-five.
