AN IMPROVED WINDLASS FOR WORKING SHIPS, ANCHORS AND CABLES
Year: 1884

page_text: JAMES BREMNER, Engineer of 66 Wright Street, Hull, does hereby declare the
nature of his invention for AN IMPROVED WINDLASS FOR WORKING SHIPS, ANCHORS
AND CABLES to be as follows:-
The invension consists firstly in the method of driving, connecting & dis-
connecting the Main shaft with the Gipsy wheel of the windlass. This is accom-
plished by means of two or more pauls which are pushed outwards from the centre
of the shaft by means of a disc which can be moved round the shaft & to which
the inner ends of the pauls are fixed eccentrically, the outer ends passing through
the rim of a driving disc keyed on the shaft & when the windlass is in gear being
forced outwards to catch against stops cast on the flanged rim of the Gipsy wheel
& thus carrying it round with the driving disc. When the pauls are drawn back
inside the rim of the driving disc the Gipsy wheel is. released & being loose on the
shaft allows the cable to run out, the rim at the same time forming a brake to
control the running out of the Cable.
•
The second part of the invention relates to the arrangement of the stops for
controlling the running of the cable and holding it when the anchor is down."
The ordinary, gripping block with groove into which the cable can drop &
shoulder for it to catch against when dropped is cast on the side frame of the
windlass but it has an arched top, the tripping block being fitted with a similar
arched top so that not only can the tripping block be lowered to allow the cable.
to drop into the groove & against the shoulder in the gripper, but if the cable does
not then catch it can be forced upwards against the top of the gripper by raising
the tripping block, thus forming a double check on the cable when running out and
when the anchor is down.

down, by raising the lever the cable can be pressed down into the groove & shoulder
in the bottom of the gripper, which will prove an effective stop whilst the ship is
anchored.
Although the drawings sent herewith & hereto annexed only shew a steam
windlass, my invention is equally applicable if the windlass is worked by hand or
any other power only, or driven from the winch by a messenger chain.
Having now particularly described & ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The arrangement of windlass as described herein & shewn by the annexed
drawings.
2nd In windlasses the arrangement of discs & pawls by means of which the
gipsy wheel (pulley) can be thrown in & out of gear, all substantially as described
and illustrated in the accompanying drawings.
3rd In windlasses the interposition of the gripper & tripping block by which the
cable can be instantly controlled or stopped when it is running out-Thus
preventing the cable from gathering too much way, or breaking the pulley or
losing the anchor and chain altogether, all substantially as described & illustrated
in the accompanying drawings..
Dated this twenty sixth day of November one thousand eight hundred &
eighty tour.
