PROVISIONAL SPECIFICATION.
Improvements in Wire Rope Wheels for Lifting, Lowering, and
Hauling Loads.
THOMAS MEACOCK 348 Soho Road Handsworth in the County of Stafford
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to improvements in wheels, for lifting, lowering and hauling
loads through the medium of wire rope and consists of forming a groove at periphery
of the wheel having recesses made in the said groove which recesses are a fac-simile
of the form of the portion of wire rope passing over same; these recesses are shaped
to receive the strands of the wire rope used and are inclined to suit the lay of the
rope thus the rope becomes imbedded for nearly half its circumference in the afore
described recessed groove creating a locking or engaging contact between the wire
rope and the said recessed groove formed at periphery of the wheel this engaging
contact will permit the full power of the rope being transmitted through the said
wheel for lifting lowering or haulage of loads. To keep the rope imbedded in the
recessed groove of said wheel a guard or shield is fixed over that portion of the wheel
periphery at any time engaging with the rope the guard would preferably be fixed
over about one half of the circumference of the said wheel, the said guard or shield
may be fixed to the framework containing the said wire rope wheel, or to any
adjacent object. The number of recesses in the said wheel would have to be such
that the strands would enter the recesses successively for the whole length of the
rope used.
In cast wheels the recesses could be cast in same from a mould preferably formed
from a piece of the rope to be used on the wheel; in forged wheels the recesses may
be formed by a die or dies operated by stamping or pressing; or the said recesses
may be formed by revolving cutters or by hand operated chisel.
The object of my invention is to produce a wheel whereby a wire rope, can be
used for lifting, lowering or hauling loads by passing over a portion of the peripheral
recessed groove afore described requiring only a width approximately equal to the
diameter of the wire rope used whereas in the present system of anchoring the rope
to a barrel or drum and coiling the rope thereon occupies considerable space; this
is particularly objectionable in lifting blocks as the pull becomes out of the vertical
plane.
My improvements permits the pull of rope always being in the same plane and
this is very convenient in suspended lifting tackle also for lifts where several ropes
are required they can be accommodated in grooves as afore-described formed parallel
to each other on the lifting wheel. The said recessed groove or grooves may be
formed on a portion of a gear wheel or upon an independent wheel as afore-
described.

Improvements in Wire Rope Wheels for Lifting, Lowering, and
Hauling Loads.
THOMAS MEACOCK 348 Soho Road Handsworth in the County of Stafford
Mechanical Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to improvements in wheels for lifting lowering, and hauling
loads, through the medium of wire rope and consists of forming a groove at periphery
of the wheel, having recesses made in the said groove which recesses are a facsimile
of the form of the portion of wire rope passing over same; these recesses are shaped
to receive the strands of the wire rope used and are inclined to suit the lay of the
rope, thus the rope becomes imbedded for nearly half its circumference in the afore
described recessed groove creating a locking or engaging contact between the wire
rope and the said recessed groove formed at periphery of the wheel, this engaging
contact will permit the full power of the rope being transmitted through the said
wheel for lifting, lowering or haulage of loads.
To keep the rope imbedded in the recessed groove of said wheel a guard or
shield is fixed over that portion of the wheel periphery at any time engaging with
the rope; the guard would preferably be fixed over about one half the circumference
of the said wheel, the said guard or shield may be fixed to the framework containing
the said wire rope wheel, or to any adjacent object.
The number of recesses in the said wheel would have to be such that the strands
would enter the recesses successively for the whole length of the rope used.
In cast wheels the recesses could be cast in same from a mould preferably formed
from a piece of the rope to be used on the wheel; in forged wheels the recesses
may be formed by a die or dies, operated by stamping or pressing, or the said
recesses may be formed by revolving cutters, or by hand operated chisel. The object
of my invention is to produce a wheel whereby a wire rope can be used for lifting,
lowering, or hauling loads by passing over a portion of the peripheral recessed
groove afore-described; requiring only a width approximately equal to the diameter
of the wire rope used; whereas in the present system of anchoring the rope to a
barrel or drum and coiling the rope thereon occupies considerable space, this is
particularly objectionable in lifting blocks, as the pull becomes out of the vertical
plane.
My improvement permits the pull of rope always being in the same plane, and this
is very convenient in suspended lifting tackle also for lifts, where several ropes are
required they can be accommodated in grooves as afore-described formed parallel to
each other on the lifting wheel.
The said recessed groove or grooves may be formed on a portion of a gear wheel
or upon an independent wheel as afore-mentioned.
I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
'Fig. 1 shews front elevation and Fig. 2 side elevation; A is the wire rope wheel
having recesses B, at periphery a facsimile of the portion of the wire rope engaging
with same, C represents the wire rope which is shewn of two strands only to give
defined recesses in wheel groove for heavy loads, when large size wire rope is used
more than two strands may be adopted.
Having now particularly described and ascertained the nature of my invention,
and the manner in which the same is to be performed, I declare that I claim as my

The construction and use of a wheel having one or more grooves at periphery
with recesses formed therein a fac-simile of the portion of the wire rope engaging
with same.
