Berks Civil Engineer for an invention of. "IMPROVEMENTS IN PULLEYS AND
WHEELS"
PROVISIONAL SPECIFICATION left by the said George William Beynon at
the Office of the Commissioners of Patents on the 23rd March 1882.

"IMPROVEMENTS IN PULLEYS AND WHEELS
"
.
My Invention relates to Improvements in pulleys or wheels and has for its
.object to provide a pulley or wheel in which the maximum of strength is combined
with the minimum of weight and as applied principally to wheels used as pulleys
to obviate the risk of injury to the operator which at present exists when straps or
bands have to be shipped thereon:
According to my said Invention a pulley is constructed with a rim or flange
turned inward from or connected to the periphery and projecting inwards from
the periphery towards the axis, the rims or flanges on the opposite sides of the
pulley being either parallel or inclined inwards or outwards.
The edges of the rim may be covered by channel or edge-pieces turned
thereover
•
The connection of the hub or axle box of a pulley or wheel with its periphery
to be effected by a disc of thin sheet metal corrugated throughout or at the part
only towards the hub or axle box and attached to the hub or boss by similarly
formed projections or grooves carried thereby and to the inner side of the outer
portion or periphery by any suitable means such as to a web formed in or about
the central line of the interior thereof for the purpose:
In combination with the periphery constructed as before described tubular
spokes may be used in place of the aforesaid corrugated disc:
Where great width of periphery is required the wide periphery may be supported
Price 6d1

page_text: by more than one hub or, axle box connected by a disc as before described, or by
hollow spokes, or the like to the inside of the periphery or to the flange which
projects inwards on either side as before described
The wheels or pulley may be formed in duplicate halves and attached together
after being placed upon their shaft by connecting plates and pins and bolts and
nuts or made in one if preferred:
The improvements are applicable to other wheels than pulleys (for example the
corrugated disc before described may be used for connecting the rim and hub of
the wheels of velocipedes in which case the said disc is preferably of thin sheet
steel) or for any other purpose or use to which the said wheel or pulley may be
suited.

IN PULLEYS AND WHEELS"
"IMPROVEMENTS
My Invention relates to Improvements in pulleys or wheels and has for its
object to provide a pulley or wheel in which the maximum of strength is combined
with the minimum of weight and is principally applicable to wheels used as pulleys
with the object also of obviating the risk of injury to the operator which at present
exists when straps or bands have to be shipped thereon but the said Invention is
applicable also to other wheels and the like
And in Order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 is a side elevation and Figure 2 is a transverse section of a pulley or
wheel constructed according to my Invention
The periphery a is constructed on either side with a rim or flange a² turned
inwards from, or connected to, the said periphery and projecting inwards from the
periphery and towards the axis as shewn-The opposite rims or flanges in this
example are shewn as being parallel with each other but they may be inclined
towards, or from, each other-In figure 3 I have shewn various suitable forms or
positions of the flanges or rims but I do not limit myself to such forms or
positions The edges of the rim may be covered by channel or edge pieces turned
thereover as represented in Figure 4
The connection of the hub boss or axle box of a pulley or wheel with its
periphery may be effected by a disc or annulus of thin sheet metal b corrugated
throughout or at the part only towards the hub, boss, or axle-box, the said disc
being connected to the said hub, boss, or axle-box by being fastened against, or
between, similarly formed projections, or grooves, c, carried thereby, or formed
thereon The connection of the said disc to the periphery of the wheel or pulley
may be effected in any suitable way such as by a web b formed at the outer edge
of the disc or on the interior of the periphery of the wheel or pulley for the purpose
of the said connection.
In place of this disc ordinary or other spokes or means of connection may be
employed if preferred A convenient form of spoke is shewn in Figure 5-The
outer end of the spoke is split and each part is splayed out in reverse directions
each to form a foot on either side of the spoke for rivetting, or otherwise fixing, to
the periphery Or the spoke may be simply bent at its end to one side without
being split-Where great width of periphery is required the wide periphery may
be supported by more than one hub boss or axle box each being connected by a
disc or by spokes to the periphery as before described with regard to one hub boss
or axle box-When the pulley or wheel is made in parts or halves connected
together the connection of the periphery may be effected in any convenient way
for example by a plate and rivets, or bolts and nuts, as shewn in Figure 6 or the
connection may be made (in addition to, or substitution for, the fastening at the
periphery) at the junction of the parts of the webs a² for example by a countersunk
bolt nut and washer as in Figure 7 the bolt engaging in a hole formed partly in
each of the adjacent parts of the sections to be connected or the fastening may be
effected by an eyelet fastening as shewn in Figure 8.

page_text: When the wheels or pulleys are formed in halves or parts attached together the
parts of the hub boss or axle box may be connected by bolts and nuts in the usual
way The wheels or pulleys may however be made whole instead of in separate
halves or parts
Figure 9 is an illustration of the application of the Invention to a pulley-coupling
for shafts the coupling box taking the place of the boss hub or axle box the pulley
portion being provided with a rim or flange a² according to my Invention
The disc b may be corrugated as before described or it may be flat as shewn
The corrugated disc or annular sheet metal connection between the hub and
periphery may be employed for pulleys and wheels generally such for example as
for rope pulleys or for the wheels of vehicles
Where pulleys or wheels are exposed on one side only there may be a rim or
flange a² on that side only if desired
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is
First The application to, and use with, the periphery of pulleys, wheels, and
the like, of a rim, or flange, or rims, or flanges, (a²) substantially as and for the
purpose described with reference to the accompanying drawings
Second The application to, and use with, pulleys, wheels, and the like, of a
corrugated, or partially corrugated, disc, annulus, or ring-like metallic sheet, for
forming the connection between the central part, or hub, boss, or axle-box, and the
exterior part, or rim, or periphery, substantially as hereinbefore described and
illustrated in the accompanying drawings
Third In pulleys, wheels, and the like, the construction of the rim, or periphery,
with a protecting rim, or flange, in combination with a connection between the
said inner part and the central part, or hub, boss, or axle-box, formed by a
corrugated, or partially corrugated, disc, annulus, or ring-like metallic sheet,
substantially as herein before described and illustrated in the accompanying
drawings
In witness whereof I the said George William Beynon have to this my
Specification set my hand and seal this nineteenth day of September One
thousand eight hundred and eighty two.
