IMPROVEMENTS IN HAULING AND VEERING MACHINES
Year: 1880

page_text: LETTERS PATENT to William Horatio Harfield, of the Mansion House
Buildings, in the City of London, for an Invention of "IMPROVEMENTS IN
HAULING AND VEERING MACHINES."
PROVISIONAL SPECIFICATION left by the said William Horatio Harfield
at the Office of the Commissioners of Patents on the 17th November 1880.
WILLIAM HORATIO HARFIELD, of the Mansion House Buildings, in the City
of London. "IMPROVEMENTS IN HAULING AND VEERING MACHINES."
This Invention consists of improvements in the apparatus used in hauling or
veering ropes, and it is particularly applicable for use for hauling, hoisting, and
veering on board ship.
An apparatus now in use consists of two multi-grooved barrels connected together
by gearing several turns of the rope passing partly round the grooved barrels.
Now according to my Invention I apply a frictional connector between the
barrels and the heaving in or the pawling gear of the hoisting machine, and I
support the overhanging ends of the two spindles upon which the multi-grooved
barrels arc mounted by a movable strut passing from the one to the other.
I also provide the barrels with flanges which roll the one on the other.

the said William Horatio Harfield in the Great Seal Patent Office on the
17th May 1881.
WILLIAM HORATIO HARFIELD, of the Mansion House Buildings, in the City
of London. "IMPROVEMENTS IN HAULING AND VEERING MACHINES."
This Invention consists of improvements in the apparatus used in hauling or
veering ropes, and it is particularly applicable for use for hauling, hoisting, and
veering on board ship.
An apparatus now in use consists of two multi grooved barrels connected together
by gearing several turns of the rope passing partly round the grooved barrels.
Now according to my Invention I apply a frictional connector between the
barrels and the heaving in or the pawling gear of the hoisting machine, and I
support the overhanging ends of the two spindles upon which the multi grooved
barrels are mounted by a moveable strut passing from the one to the other.
I also provide the barrels with flanges which roll the one on the other.
In the Drawings hereunto annexed, I have shewn my improved hauling and
veering mechanism applied to a windlass.
Figure 1 is a plan, and Figure 2 a side elevation of the windlass and hauling and
veering mechanism.
In this case the windlass spindle A is prolonged beyond its standard B upon the one
side; this prolonged end of spindle carries a multi grooved pulley C which
contains in its interior a frictional brake and connector so arranged that upon
working the handwheel D the spindle of the windlass may be connected with the
pulley or disconnected as may be desired, or the pulley may be allowed to revolve
at a greater or less resistance, as may be required. Preferably, I use a friction
connection, such as is described in the Specification of a former Patent granted to
me, No. 442, in the year 1867, but other forms of friction coupling or connection
may be used. The pulley C has upon one end a spur wheel, flanged or shrouded,
gearing into another spur wheel, also flanged or shrouded, upon a corresponding
multi grooved pulley E; now these wheels are geared together, so that the two
shrouds upon the wheels roll one upon the other, thus relieving the spindles from
some of the strain which would otherwise come upon them. The pulley E revolves
freely upon its spindle; the spindle is prolonged through the pulley, and the
moveable strut F comes upon this prolonged end and upon the end of the windlass
spindle; its use is to prevent the two spindles being bent towards each other from
the multiplied strain of the several turns of the rope round the pullies.
Having thus described my Invention, I would state that I claim,-
First. The construction of apparatus for hauling or veering rope in which two
multi grooved pullies are connected or disconnected from the driving shaft by
means of a friction brake or connector.
Second. The arrangement of the two multi grooved pullies by which the
shrouds of the two wheels roll together and reduce the strain upon the spindles.
Third. The moveable strut F placed upon the overhanging ends of the spindles
of the two multi grooved pullies for the purpose described.
In witness whereof, I, the said William Horatio Harfield, have hereunto set
my hand and seal, this Sixteenth day of May, in the year of our Lord
One thousand eight hundred and eighty-one.
W. H. HARFIELD. (L.S.)
