POSES.
Instead of, as in steam winches and other such contrivances, passing the hauling
rope, hawser, or cable over the revolving whelps, or curved bits, or the cylinderical
barrels, mounted on shafts parallel to or with each other, or over other such con-
trivances so disposed, wherein, whereon, and whereby great friction and chafing is
produced, I substitute this Invention for the purpose of avoiding such mischief;
and as applied to deck winches and such like apparatus with horizontal shafts and
overhanging groved drums, pulleys, or whelps, I substitute for, such two parallel
shafts, shafts or spindles arranged, disposed, and worked angularly, the one with
the other, to such an extent as will be regulated by the diameter of the rope, warp,
or hawser intended to be employed, and which in turn will be governed by the
diameter of the groves in the double or treble sheaves or pullies on each spindle,
one or both of each may be driven, the angular position of the shafts causing the
ropes to clear each other at their crossings, or where they pass each other in making
the figure of eight," in which they are coiled over the " bollards" or bit, or are
'belayed" for "holding on," as for "bringing to," as in ferry steamers on going
alongside, and "bringing up to " a landing stage.
"
"
For such purposes and where fitted on board of a steam ferry boat the wheel or
other gearing, as well as the power, may be applied below the deck, whilst the
pullies, drums, sheaves or bits would stand on the upper ends of the vertical. but
angularly disposed shaft, and above the deck in a convenient position.
The angular shafts when geared together for the purpose of being driven may
be geared by any of the well-known means in ordinary use, or by means of an
intermediate pinion, which will transmit motion to both shafts simultaneously.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Taylor in the Great Seal. Patent. Office on the 29th June

JAMES TAYLOR, of Mark Lane, London; and Birkenhead, Engineer. "IMPROVE-
MENTS IN APPARATUS AND GEARING FOR HOISTING, HAULING, AND SUCH LIKE
PURPOSES."
My Invention consists in placing or disposing the axes or shafts of pulleys and
rope gearing at an angle to and with each other, instead of as at present in steam
winches and other such contrivances passing the hauling rope, hawser, or cable over
the revolving whelps or curved bits, or around the cylindrical barrels (mounted on
shafts parallel to or with each other, or over other), such contrivances so disposed,
wherein, whereon, and whereby great friction and chafing is produced. I sub-
stitute this "Invention for the purpose of avoiding such mischief or mischievous
consequences and loss of power. As applied to deck winches or capstans, and
such like apparatus with horizontal shafts and overhanging grooved drums, pulleys,
or whelps, I substitute. for such two parallel shafts, shafts or spindles arranged,
disposed, or worked angularly to such an extent as will be regulated by the
diameter of the rope, warp, hawser, or chain cable intended to be employed. The
angular position of these shafts causes the ropes to clear each other at their
crossings, or where they pass each other, as in making the "figure of eight," in which
they pass or are coiled over the "bollards or bits (of which there may be one or
more grooves), or are belayed for "holding on," or for "bringing to," as in steam or
sailing ship on going alongside and bringing up to a stage or pier.
و"
Where capstans are used one spindle may be vertical, and the necessary angle
given to the other.
The aforesaid angular shafts, when geared together for the purpose of being
driven, may be geared by any of the well-known mechanical means in ordinary
use, or by means of an intermediate pinion or pinions, which will transmit motion
to both shafts simultaneously.
In some cases, where power has to be communicated to one spindle or shaft, the
double or other pulley may run free or loose upon the end of the other shaft or
spindle.
For communicating motion to ropes in a vertical direction, such as for lifting
purposes for working the top gearing wheels, &c., the shafts may be horizontally
placed, but angularly disposed, so that the same result is obtained by preventing
the ropes coming in contact (or passing each other) and chafing.
In every case, according to this Invention, the axles or shafts are placed and
work at an angle with each other, so that the grooved drums or pullies, around
which coils of the rope pass, do so at an angle with and to each other, but not in
contact by reason of the angularity of the shafts.
In applying this Invention to steam winches and such like apparatus, the
ordinary horizontal shaft and its overhanging rope drum or head may be supple-
mented by corresponding drums or grooved pulleys mounted or placed at an angle,
therewith either below the line of the driven barrel or in any convenient-
position.
.
For hoisting tackle, or for communicating motion to hauling gear, the power or
means of transmitting motion is communicated to one or.. to both of the angularly
disposed shafts, and the pulleys connected therewith, either by means of tangent or

page_text: worm wheels driven by means of a screw or screwed shaft geared thereunto, but on
opposite sides, or by means of spur gearing with the teeth suitably disposed.
In each case, and wherever the same construction has to be adapted, a similar
mode of mounting and applying will have to be adopted to prevent the contact and
friction between the rubbing surfaces of the ropes; drums or heads may be so con-
structed as to allow of their sliding up or down for the purpose of the free adjust-
ment to the "pull" of the rope whilst in action.
In the accompanying Sheet of Drawings I have shown five Figures illustrating
my Invention.
Figure I is a side elevation, showing two "bollards" or bits, and as one of the
means of driving by hand.
Figure 2 is a plan view of Figure 1, showing one of the arrangements I intend
to adopt for the purpose of working my Invention.
Figure 3 is a perspective view of the apparatus, which illustrates how a rope is
applied.
Figures 4 and 5 are end elevations of the former Figures showing the "bollards"
or bits at right and left angles.
Having now described my Invention for improvements in apparatus and gearing
for hoisting, hauling, and such like purposes, I wish it to be understood that what
I claim is,-
Firstly. Placing or disposing the axes or spindles of non-driven or mechanically
disconnected rope drums at an angle to or with each other, as herein described.
Secondly. Placing or disposing the shafts or axes of machine geared or driven
drums, or rope gear, where the same is intended to be driven by power, at such an
angle so that the coils do not pass in frictional contact, in the manner and for the
purposes herein set forth.
In witness whereof, I, the said James Taylor, have hereunto set my hand
and seal, this Twentieth day of June, One thousand eight hundred and
seventy-seven.
