page_text: RICHARD WOODHOUSE and SAMUEL MITCHELL, of Brighouse, in the County of
York, Engineers and Founders, seek leave to amend the specification of Letters
Patent, No. 5,112 of 1884, as shown in red ink in the copy of the original
specification hereunto annexed, by omitting the second claim stated on page 3 of
5 said specification.
-That the arms of
My reasons for making this amendment are as follows :—
pulleys have been made of oval section for some time past by others.
In the matter of the application made by Richard Woodhouse and Samuel Mitchell
for leave to amend the Specification of Letters Patent N° 5112 of 1884.
THE COMPTROLLER-GENERAL'S DECISION.
I hereby grant leave to the said Richard Woodhouse and Samuel Mitchell to
amend the said Specification in the manner proposed in their application of the
15th June 1885.

Comptroller-General,

page_text: We, RICHARD WOODHOUSE & SAMUEL MITCHELL, of Brighouse, in the County
of York, Engineers and Founders, do hereby declare the nature of our invention
for IMPROVEMENTS IN THE MANUFACTURE OF DRUMS OR PULLEYS to be as
follows:-
The outer rims of the drums or pulleys made according to our present invention
may have plain faces for flat belts, with the edges turned in or rolled to special
sections, they may be voluted for ropes, or have V grooves for square belts, as may
be required to suit the various systems of driving. They may be rolled by any
suitable machinery out of iron or steel; so as to be without joint or may be of one
or two parts joined together in any well known manner. Each drum or pulley has
one or more bosses according to the width of the outer rin, and each boss has
a flange or Hanges to which the arms are fixed at their inner ends.
Each arm leads from one face of one of the boss flanges to the outer rim to
which it is secured, and then turns to the other face of same flange or to another
flange according to the width of the outer rim. For larger drums or pulleys the
arms may be braced diagonally by ribbon bracing, and for all sizes the arms and
bracings are by preference of flat or oval section, or have both faces convex, fixed
flat wise to the bosses and outer rims so as to present the least resistance. to the air
when revolving.

page_text: We, RICHARD WOODHOUSE and SAMUEL MITCHELL, of Brighouse, in the County
of York, Engineers and Founders, do hereby declare the nature of our invention
for IMPROVEMENTS IN THE MANUFACTURE OF DRUMS OR PULLEYS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The outer rims of the drums or pulleys made according to our present invention,
may have plain faces for flat belts with the edges turned in or rolled to special
sections, they may be voluted for ropes, or have ✓ grooves for square belts, as may
be required to suit the various systems of driving. They may be rolled by any
suitable machinery out of iron or steel so as to be without joint, or may be of one
or two parts joined together in any well known manner.
Each drum or pulley has one or more bosses according to the width of the outer
rim, and each boss has a flange or flanges to which the arms are fixed at their inner
ends. Each arm leads from one face of one of the boss flanges to the outer rim to
which it is secured, and then turns to the other face of same flange or to another
flange according to the width of the outer rim.,
For larger drums or pulleys the arms may be braced diagonally by ribbon
bracing, and for all sizes the arms and bracings are by preference of flat or oval
section or have both faces convex, fixed flatwise to the bosses and outer rims, so as
to present the least resistance to the air when revolving.
And in order that our invention may be understood we will now describe it with
reference to the sheet of drawings accompanying this specification, like reference
letters being used to denote the same or similar parts where repeated on the various
diagrams.
Figure 1 is an elevation and figure 2 is a section of a narrow pulley with plain
weldless rim A, flanged boss B, and oval or flat arms C, the arms being rivetted to
the boss and rim. Figure 3 is an elevation and figure 4 is a section of a narrow
split pulley with plain rim. Figure 5 is an elevation and figure 6 is a section of a
broad split pulley with the rim A beaded on edges and joined together at D, the
boss is in two parts joined at E, and the arms have diagonal bracings F. Figure 7
shews a section of pulley having a beaded rim and the arms leading from the boss
Hanges are brought together and fastened to each other before touching the rim.
Figures 8 and 10 shew broad pulleys with beaded rims and two sets of arms.
Figure 9 shews a section of a pulley with convex rim having two fins on inner
face for securing the arms to. Figure 11 shews a section of a pulley with grooves
for rope gearing, having arms with diagonal bracings. Figure 12 shews a section
of rim with V grooves for square belts, and figure 13 shews grooves for a special
section of belting. The grooved pulleys may be made as split pulleys and jointed
at the rin and boss in any well known manner,

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
First. Rolling the rims of driving pulleys of iron or steel to the sections
substantially as shewn and described herein.
Second.-Making the arms of driving pulleys of oval section and fixing and
bracing-the-same-substantially as herein-shewn-and-described.
Second. Third. Constructing driving pulleys according to the various improved
details herein shewn and described.
