TRUVIDIONAL DIVIFICATION.
Improvements in Pulleys and Wheels.
I, RICHARD MOODY EVERY, of Uitenhage, Cape Colony, South Africa, do
hereby declare the nature of this invention to be as follows:-
My invention relates to pulleys and wheels, such for instance as are used in
wire-rope traction systems; but it is applicable to pulleys and wheels generally
where it is desired to overcome jarring and friction.
According to my invention I make the pulley, or wheel, with a tyre, or
peripheral bearing surface, formed of a moveable ring of chilled iron, or
other suitable metal, or material; and I interpose between this ring and the
circumference of the body part of the pulley, or wheel, an elastic bed, or ring,
the pulley, or wheel, being provided with means to prevent displacement of
the said rings.
The following is a convenient construction according to my invention, but
I do not limit myself to the precise details.
The body of the pulley, or wheel, consists of a flanged circumferential part
fixed to, or cast with, the spokes and boss. On the said circumferential part
an elastic ring is placed, and on this is placed a ring of chilled iron whose outer
circumference is grooved, or formed in any necessary manner, to receive a rope,
or band, or the like. An annular plate, or ring, constituting a second flange, is
then secured to the body part of the wheel, which may be done by bolts, or
rivets, passed through ears thereon, or through the spokes. The said elastic
ring and chilled iron ring are thus held between the flange on the body part on
one side and that constituted by the aforesaid annular plate, or ring, on the
other side.

Improvements in Pulleys and Wheels.
I, RICHARD MOODY EVERY, of Uitenhage, Cape Colony, South Africa, 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 pulleys and wheels, such for instance as are used in
wire-rope traction-systems; but it is applicable to pulleys and wheels generally
where it is desired to overcome jarring and friction.

page_text: According to my invention I make the pulley, or wheel, with a tyre, or
peripheral bearing surface, formed of a moveable ring of chilled iron, or
other suitable metal, or material; and I interpose between this ring and the
circumference of the body part of the pulley, or wheel, an elastic bed, or ring,
the pulley, or wheel, being provided with means to prevent displacement of
the said rings.
I will describe with reference to the accompanying drawing a convenient
construction according to my invention, but I do not limit myself to the precise
details illustrated.
Figure 1 is a transverse section of the complete pulley or wheel and Figure 2
is a side view of the body part of the pulley or wheel as seen from the direction
of the arrow Figure 1.
The body of the pulley, or wheel, consists of a flanged circumferential part A
fixed to, or cast with, the spokes a and boss 2. On the said circumferential
part an elastic ring B is placed, and on this is placed a ring C of chilled iron
whose outer circumference is grooved or formed, in any necessary manner, to
receive a rope, or band, or the like indicated at d. An annular plate, or ring E
constituting a second flange opposite the flange of the part A is then secured to
the body part of the pulley, or wheel, which may be done by bolts, or rivets,
passed through ears thereon, or through the spokes or enlargements of the spokes
as indicated in the drawing at f. The said elastic ring B and chilled iron
ring C are thus held between the flanged circumferential part A on one side and
that constituted by the aforesaid annular plate or ring E on the other side. Of
course the pulley or wheel may be made of any required size and with any
desired number of spokes or with a disc form of body part in place of spokes..
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A pulley, or wheel, having a peripheral bearing surface and an elastic bed,
or ring between such bearing surface and the circumference of the body part of
the pulley, or wheel, and means for maintaining the said peripheral bearing
surface and elastic bed or ring, in position, substantially as hereinbefore de-
scribed.
2. A pulley or wheel, constructed as hereinbefore described and illustrated in
the accompanying drawing.
