PROVISIONAL SPECIFICATION.
Improvements in Pullies, Wheels, Sheaves, Runners, and the like.
I, ALFRED STEEL of Meadow Hall Road, Brightside, Sheffield, in the County
of York, Engineer and Iron and Steel Founder, do hereby declare the nature of
my said invention to be as follows:
:.
My present invention relates to improvements in "pullies, wheels, and runners
manufactured in a manner similar to that described in the Complete Specification
of my Patent A.D. 1887 February 4th No. 1768, which as set out in the said
Specification is for improvements in the manufacture of a roller or pulley by
casting the two ends or flanges separately provided with grooves into which is
fitted a steel sheet to form the barrel or wearing surface of the roller or pulley and
into which is also fitted a steel spindle passing through the centres of the ends and
either screwed or shrunk tightly thereon so that the ends, the barrel and the spindle
are all secured firmly together forming a complete roller or pulley' as the case may
be, and by the particular form of construction therein described a roller or pulley
of greater strength and durability, combined with lightness and 'cheapness is
obtained..
!
My present invention relates howover to pullies, wheels, sheaves, runners and
the like which are much. narrower between the flanges than the rollers described
and illustrated in my former Patent (No. 1768, A.D. 1887,) and is more
particularly applicable to pullies and sheaves having narrow grooved rims, or to
wheels and runners which have a narrow wearing surface between two flanges.
The object of my present invention like that of my former one last referred to,
is to secure greater durability of the wearing surfaces of such pullies, wheels,
sheaves, runners and the like, and to make such wearing surfaces removable and
interchangeable.
As the principle of my invention and the manner of carrying the same into
effect is the same to whichever of the above purposes it is applied a description
of it as applied to a grooved pulley or sheave (hereinafter called a pulley) will
suffice.
Such a pulley I divide circumferentially between the centre of the flanges, the
joint being so formed at the bottom of the groove that when, the two separate parts
of the rim are brought together a recess is provided for the reception of a ring of
steel or other hard substance such ring being placed in position before the two halves-
of the pulley are bolted together.
Half the arms and half the boss, the latter also being divided circumferentially,
at its cantre I attach to each half of the rim and provide with suitable lugs by which
the two halves may be bolted together, or in some cases I form the two halves of
my improved, pulley in two separate discs, each disé carrying half the boss and half
the rim forming together a complete pulley in two halves divided circumferentially
and provided with bolt holes for securing the separate parts together or in the case
of small diameters the separate halves may be shrunk or screwed by nuts or otherwise
onto the spindle.
In this way such pullies may be provided with rims or liners of hardened steel
..

page_text: hardened steel or other substance in such a manner that these wearing parts may
be taken out and replaced when worn or broken.
The movable rims, liners or treads herein described. I construct of special section
which may be rolled or otherwise forined.
Dated this 30th day of January 1895.

I, ALFRED STEEL, of Meadow Hall Road, Brightside, Sheffield, in the County.
of York, Engineer and Iron Founder, 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
: r.
-My present invention relates to improvements in pullies, wheels, and runners
manufactured in a manner similar to that described in the Complete Specification
of my Patent A.D. 1887, February 4th, No. 1768, which as, set out in the said.
Specification is for improvements in the manufacture of a roller or pulley by casting
the two, ends or flanges separately, provided, with grooves into which is fitted, a.
steel sheet to form the barrel or wearing surface of the roller or, pulley and into.
which is also fitted a steel spindle passing through the, centres of the ends and.
either screwed or shrunk tightly thereon so that the ends, the barrel and the
spindle, are all secured firmly together forming a complete, roller or pulley, as the
case may be and by the particular form of construction therein described a
roller or pulley of greater strength and durability combined with lightness and
cheapness is obtained.
My present invention relates however to pullies, wheels, sheaves, runners and the
like which are much narrower between the flanges than the rollers described and
illustrated i
d'in my former Patent (No. 1768, A.D. 1887) and is more particularly
applicable to pullies and sheaves having narrow grooved rims, or to. wheels and
runners, which have a narrow wearing surface between two flanges.
The object of my present invention like that of my former one last. referred
to, is to secure greater durability of the wearing surfaces of such pullies, wheels,
sheaves, runners and the like, and to make such wearing surfaces removable and
interchangeable.

As the principle of my invention and the manner of carrying the same into
effect is the same to whichever of the above purposes it is applied a description of
it as applied to a groove. pulley or sheave, (hereinafter called a pulley), will
suffice.
L
Such a pulley. I divide circumferentially between the centre of the flanges, the
joint being so formed at the bottom of the groove that when the two separate.
parts are brought together a recess is provided for the reception of a ring of steel
or other hard substance, such ring, being placed in position before the two halves
of the pulley are bolted together.
1.
Half the arms and half the boss, the latter also being divided circumferentially
at its centre, I attach to each half of the flanged rim and provide with suitable lugs
by which the two halves may be bolted together, or in some cases I form the two halves...
of my improved pulley in two separate discs, each disc carrying half the boss,aud.
arms and half the flanged rim, forming together a complete pulley in two halves,
divided circumferentially and provided with bolt holes for securing the separate,
parts together or in the case of small diameters the separate halves may be shrunk
or secured together by outs, or otherwise, onto the spindle.
