Improvements in the Hubs of Wheels suitable for Cycles and other
purposes.
I, JOHN HENRY PLAYER, of J, Wren Street, Coventry, in the County of Warwick,
Tool Maker, do hereby declare the nature of my said invention to be as follows:-
My invention has for its object improvements in the hubs of wheels suitable for
cycles other purposes by which I am enabled to do away with the greater portion of
the screwing of the various parts of the hubs thus greatly reducing the cost of
manufacture and also to more easily and quickly adjust the wearing parts of the hub
which is effected by means of the cups.
In carrying my invention into practice I form my hub shell either from a stamping
or casting or froin the solid bar with a plain hole straight through and at one end
this hole is slightly enlarged so as to form a shoulder in the interior for the fixed cup
or half ball race to bed against.
This cup which is preferably made of steel and hardened and tempered fits into
the enlarged end of the hub the inner end butting against the internal shoulder and
The opposite cup
is fastened in position by sweating or pegging or by other means.
which slides into the plain end of the hub is prevented from turning by ineaus of a
peg or the like which fits into a small hole formed partly in the interior of the shell
of the hub and partly in the exterior of the cup and this cup when placed in
position protrudes slightly beyond the outer edge of this end of the hub for adjusting
purposes.
The adjusting of the hub is effected by means of a nut or the like which screws
onto the exterior of this end of the shell of the hub the said end being screw threaded
externally for this purpose.
This adjusting nut is formed with an internally projecting flange which when adjusted
in position bears against the outer surface of the loose cup and is preferably formed
externally with a number of flats say for instance six so as to receive a spanner or the
like.
In the centre of each of these flats a small hole is forined which is tapped to receive
a set pin for holding the adjusting nut in position which set pin when secured into
one of these holes also takes into a corresponding elongated hole formed in this end
of the hub shell. Or there may be one tapped hole formed in the adjusting nut and

shell to receive it. This cup is locked in position by a set pin which screws into a
hole formed in the shell the inner end of which set pin fits into an elongated recess
formed on the outer surface of the cup or vice versa. The spindle on which the cones
or other halves of the ball races fit is formed with two shoulders for the inner ends of
the cones to butt against and the part of the spindle on which these cones fit is
formed plain so as to allow the cones to slide thereon and these cones are prevented
from turning by forming a snug on the spindle which takes into a recess formed in
the cone or vice versa or by other means. The sprocket wheel on the back hub is
fitted into that end of the bub in which the fast cone is placed. To adjust the

the loose cup inwards which action forces the spindle inwards also, thus adjusting
both ends of the bearing.
Improvements in the Hubs of Wheels suitable for Cycles and other
purposes.
I, JOHN HENRY PLAYER, of 5, Wren Street, Coventry, in the County of Warwick,
Tool Maker, 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:-
My invention has for its object improvements in the hubs of wheels suitable for
cycles and other purposes by which I am enabled to do away with the greater portion
of the screwing of the various parts of the hubs thus greatly reducing the cost of
manufacture and also to more easily and quickly adjust the wearing parts of the hub
which is effected by means of the cups.
In carrying my invention into practice I form my hub shell either from a stamp-
ing or casting or from the solid bar with a plain hole straight through and at one
end this hole is slightly enlarged so as to form a shoulder in the interior for the fixed
cup or half ball race to bed against. This cup which is preferably made of steel and
hardened and tempered fits into the enlarged end of the hub the inner end butting
against the internal shoulder and is fastened in position by sweating or pegging or
by other means. The opposite cup which slides into the plain end of the hub when
placed in position protrudes slightly beyond the outer edge of this end of the hub
for adjusting purposes and this cup if found necessary may be prevented from turn-
ing by means of a peg or the like which fits into a sinall hole formed partly in the
interior of the shell of the hub and partly in the exterior of the cup.
The adjusting of the hub is effected by means of a nut or the like which screws
onto the exterior of this end of the shell of the hub the said end being screw
threaded externally for this purpose.
This adjusting nut is formed with an internally projecting flange which when ad-
justed in position bears against the outer surface of the loose cup and is preferably
formed externally with a number of flats say for instance six so as to receive a
spanner or the like.
In the centre of each of these flats a small hole is formed
which is tapped to receive a set pin for holding the adjusting nut in position which
set pin when screwed into one of these holes also takes into a corresponding elon-
gated hole formed in this end of the hub shell. Or there may be one tapped hole
formed in the adjusting nut and a number of elongated holes formed in the end of
the shell of the hub. Or I may form a screw thread on the outer surface of the
loose cup and tap this end of the shell to receive it. This cup is locked in position
by a set pin which screws into a hole formed in the shell the inner end of which set
pin fits into an elongated recess formed on the outer surface of the cup or vice versu.
The spindle on which the cones or the other halves of the ball races fit is formed with
two shoulders for the inner end of the cones to butt against and the part of the
spindle on which these cones fit is formed plain so as to allow the cones to slide

page_text: which takes into a recess formed in the cone or vice versa, or by other means. The
sprocket wheel on the back hub is fitted onto that end of the hub in which the fast
cone is placed. To adjust the bearing the set pin is unscrewed and the adjusting
nut tightened up thus forcing the loose cup inwards which action forces the spindle
inwards also, thus adjusting both ends of the bearing.
In order that my invention may be more clearly understood and easily carried into
practical effect I have appended hereunto a double sized sheet of drawings upon which
I have illustrated examples of my improved hub.
Figure 1 is a front view of the back hub of a cycle constructed according to my
invention.
Figure 2 is an end view of Figure 1.
Figure 3 is a part sectional view of Figure 1.
Figure 4 is a side view of the adjusting nut.
Figure 5 is a part sectional front view of a modified form of my hub.
Figure 6 is an end view of Figure 5.
Figure 7 is a side view of the adjusting washer as shewn at Figures 5 and 6.
In carrying my invention into practice I form the shell A of my hub either
from a stamping or casting or from a solid bar with the plain hole a¹ straight
through. This hole a¹ is slightly enlarged at the end a² so as to form the
shoulder a³ in the interior of the shell against which the fixed cup or half ball
race B beds. This cup B is preferably made of steel hardened and tempered and
when fitted in position in end a² of the shell A either by sweating pegging or by
other means the inner edges butt against the internal shoulder a³ as clearly shewn at
Figure 3. Or a flange may be formed on the outer edge of the cup to butt against
the edge of the shell instead of forming an internal shoulder. The opposite cup or
half ball race B₁ slides into the plain end at of the shell A and when the spindle S
with its cones or half ball races 8 and 82 and the balls D are placed in position in
the interior of the shell this cup B¹ protrudes slightly beyond the outer edge of the
end at so as to enable the bearing to be adjusted when necessary. The adjustment
of the hub is effected by means of the nut E which screws onto the exterior of the
end at of the shell A this end of the shell being screw threaded externally to receive
the nut. The adjusting nut E is formed with the internally projecting flange e¹
which when the nut is fixed in position bears against the outer surface of the
loose cup B and the exterior of this adjusting nut is preferably formed with a
number of flats-say for instance six-so as to receive a spanner or the like. In
the centre of each of these flats I form a small hole e² and these holes are tapped
to receive the set pin e3 which set pin when screwed into one of these holes also
takes into the corresponding elongated hole et formed in this end of the shell A
as clearly shewn at Figure 3 thereby firmly holding the adjusting nut in position.
Or instead of forming a number of tapped holes in the adjusting nut this end of the
shell A may be formed with a number of elongated holes and only one tapped hole
formed in the adjusting nut. The cones 8 and 82 may be sweated onto the spindle S
or they may be formed with a recess which takes onto a snug formed on the spindle
or vice versa a shoulder being also formed near either end of the spindle for these
cones to butt against. The sprocket wheel W screws onto the end a² of the shell A in
which the fixed cup B is placed and is locked in position by the lock washer was
clearly shewn at Figure 3.
To adjust the bearing the set pin e³ is unscrewed and the adjusting nut E tightened
up thereby forcing the loose cup B₁ inwards which action also forces the spindle
inwards also thus adjusting both end of the bearing.
In the modification as shewn at Figures 5, 6 and 7 instead of externally screw
threading the end a² of the shell A I form an internal screw thread at this end of the
shell to receive the screw threaded adjusting washer F. This adjusting washer F is
formed with a hole in its centre sufficiently large to allow it to slide onto the cone 8¹
and when fitted in position butts against the back or outer face of the loose cup B¹
as clearly shewn at Figures 5 and 6. Also formed on the screw threaded edge of this

page_text: washer are a number of slots f¹ or elongated holes to receive the set pin e³ which
screws into a hole formed in the end of the shell A for locking the adjusting washer
in position as clearly shewn at Figures 5 and 6. Or a number of holes may be
formed in the end a² of the shell and only one elongated hole or slot formed on
the edge of the adjusting washer. The outer face of the adjusting washer F is formed
with the projecting portion f2 having two or more flats to receive a spanner for
adjusting purposes. It will be easily understood that by screwing this washer F
inwards the loose cup B¹ will be forced inwards also and consequently the spindle by
which means the bearing can be adjusted when required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what

CLAIMS.
First: The improvements in the hubs of wheels suitable for cycles and other purposes
consisting essentially in forming the hub with a shell such as A one end of which is
slightly enlarged at the mouth to receive a fixed cup such as B the other end being
screw threaded externally or internally to receive an adjusting nut such as E or an
adjusting washer such as F which bear against the outer surface of a loose cup such
as B¹ the said adjusting nut or washer being held in position by a set pin such as c³
or its equivalent which screws into a hole or holes formed in the nut or in the end of
the shell A and takes into an elongated hole or holes formed in the end of the shell
or in the edge of the adjusting washer in the manner substantially as herein set forth
and as shewn upon the accompanying sheet of drawings.
Second Adjusting the bearings of wheels by forming an external screw thread on
one end of the hub shell to receive a nut such as E which bears against the outer
surface of a loose cup such as B¹ the said nut being held in position by a set pin or
its equivalent which screws into a hole or holes formed in the adjusting nut and takes
into an elongated hole or holes formed in the end of the hub shell in the
manner substantially as herein set forth and as shewn upon the drawings by
Figures 1, 2, 3 and 4.
Third Adjusting the bearings of wheels by forming an internal screw thread on
one end of the hub shell to receive a screw threaded washer such as F' which bears
against the outer surface of a loose cup such as B¹ the said washer being held in
position by a set pin or its equivalent which screws into a hole or holes formed in the
end of the hub in the manner substantially as herein set forth and as shewn upon
the drawings by Figures 5, 6, and 7.
