rim from which the arms or spokes converge to the pulley boss or hub.
The rim sections are shaped to fit over the second or inner rim and they are
united by bolts, pins or screws passed through end plates provided at the ends of
each section.
A section, or more than one, may, when required, be disconnected and removed

An Improvement relating to Pulleys for Hauling and Winding.
I, THOMAS BODYCOMBE, of 40 Queen Street, Pentre, Glamorganshire, Fitter,
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 :-
This invention relates to pulleys for hauling and winding.
The improvement which constitutes this invention, has reference to the rims of
such pulleys, that is to say, the rims on which the hauling or winding ropes or
chains bear.
In a pulley made in accordance with this invention, the rim for the rope or chain
is made in sections which are bolted or otherwise secured around a second or inner
rim, from which the arms or spokes converge to the pulley boss or hub.
The rim sections are shaped to fit over the second or inner rim, and they are
united by bolts, pins, or screws, passed through end plates provided at the ends of
each section.
A section, or more than one, may, when required, be disconnected and removed
for repair or replacement by another or others, without taking the pulley out of its
bearings.
Referring to the accompanying sheet of drawings, Fig. 1 represents, in side
elevation, part of a hauling or winding pulley fitted with a divided outer rim in

page_text: accordance with this invention. Fig. 2 is a view of that end of a portion of a rim
at which the sections meet. In the pulley illustrated in the drawings, the outer
rim is made up of two sections only. Obviously, the outer rim may consist of
more than two separate parts.
The outer rim a, which takes the hauling or winding rope or chain, is composed
of two separate sections which fit over the inner rin b and meet at a', a'. At each
end of each separate section of outer rim are situated end plates or flanges a², in
which are bolt holes for passage of bolts c by which the sections of rim are secured
together. Obviously, the rim a may be made in as many separate sections as may
be requisite or desirable.
Instead of bolts for securing the sections together, other equivalent means may
be adopted.
The separate sections of outer rim are, by unscrewing the holding devices,
readily removable for repair, replacement, or other purpose, and hence a section or
sections may be taken off the inner rim without involving unshipment of the pulley
out of its bearings, and without necessitating discarding other parts of the
pulley.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Outer rims for hauling and winding pulleys, consisting of separate and separable
sections constituting together a ring divided transversely at suitable intervals; the
said sections being adapted to fit over or lie upon and encircle the inner rim of
the pulley and held together when in place by bolts passed through end plates on
the abutting ends of the sections, or by equivalent means, substantially as
herein before described with reference to the accompanying sheet of illustrative
drawings.
Dated this 19th day of February 1897.
