Improvements in Parts of Cycles and Common Road Vehicles.
We, Frederick WATERS, of Alma Street, Aston, near the City of Birmingham,
Cycle Manufacturer, and GEORGE METCALFE DODD, of Alma Street, Aston, aforesaid,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the hubs of cycle and common road vehicle wheels and to
the bottom brackets and pedals of cycles, and has for one of its objects, a lock for
the adjustable coned clips or. the cones of the ball bearings, and for another object,
to combine in one article, a chain-wheel lock nut and bearing cone or cap whereby
large balls can be employed in the hub bearings of tandems and other multicycles
without having to increase the diameter of the chain wheel.
In carrying out my invention in connection with a barrel wheel hub, I take an
ordinary shell body part, comprising the waist, spoke flanges and heads with open
ends or mouths which are inside screwed, and with the spindle, which has ball-raced
collars at its two ends, directed axially therethrough. The adjustable she-coned
ball race consists of a cup mouth and having a hole in its outer end wherethrough
the neck of the spindle passes and being outside screwed for taking into the inside
screwed mouth of the head, thus forming an oil-retaining and dust-proof cap and
having a notched flanged edge with which the free end of a spring, tongue, catch,
detent or equivalent engages and takes in one or other of the said notches, teeth or
projections and thus holds the said adjusting cup or disc in its adjusted position.
A nut takes upon the end of the spindle, and between it and the end of the collar
or journal of the spindle, the back fork jaws come and are there held, although as
an additional precaution for preventing the rotation of the spindle, I propose to form
flats on the said spindle which are embraced by the said fork jaws.
By locking the inside coned cups or discs in their adjusted positions by means as
described, the same can be adjusted without interfering with the adjustment of the
chain and the chain can be adjusted without disturbing the adjustment of the hub
bearings which may be either of the disc-adjusting or cone and cup type.
Instead of the notched flange or circular rack being on the cone, it may be formed
on the edge of the hub ends and the spring, catch or tongue may be carried on the
cone.
Instead of the cones or cups being adjusted and locked at one end of the hub only
they may be adjusted and locked at both ends.
The combined chain-wheel lock nut and bearing cone or cup consists of a large disc
or circular plate having at the inner side of its middle a coned cup forming an inside
ball race and being outside screwed to take into the interiorly wormed and enlarged
mouth of the head at the chain wheel end of the hub, the said head being outside
screwed to take the chain wheel, which is locked by the plate or disc end of the cone
jambing its face.
The application of the first part of my invention to the locking in their adjusted,

page_text: positions of the cones or coned cups of cycle bottom bracket and pedal bearings
differs in no essential respect from its application to wheel hubs as herein described.

We, FREDERICK WATERS, of Alma Street, Aston, near the City of Birmingham,
Cycle Manufacturer, and GEORGE METCALFE DODD, of Alma Street, Aston, aforesaid,
Cycle Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to he performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to the hubs of cycle and common road vehicle wheels and
to the bottom brackets and pedals of cycles, and has for one of its objects, to
provide an efficient lock for securing the adjustable cups, cones or movable elements
of the ball bearings to the casing or fixed element of the bearing, and for another
object to combine in one article, a, chain-wheel lock nut and bearing cone or cup
whereby large balls can be employed in the back wheel hub bearings, without having
to increase the diameter of the chain wheel, which is an advantage in the bearings
of tandems and other multicycles intended to support heavy weights.
In ordinary hubs, the chain wheel is usually screwed upon a right-hand wormed
enlarged part outwards of the spoke flange and its locking ring is wormed upon a
left-hand outside screwed end of the hub of the same diameter as the opposite end,
thus necessitating the employment of like sized bearing cups and balls at each end
of the hub, unless the diameter of the chain wheel be considerably increased, which
is undesirable, whereas by the employment of a combined lock-ring and ball cup in
accordance with our invention, the enlarged part whereon the chain wheel is
screwed, admits of being chambered out and inside screwed to receive a bearing
cup whose inside ball race, balls and spindle cones may all be of a correspondingly
larger size.
Figure 1 of the accompanying drawing represents an elevation of a cycle disc-
adjusting driven-wheel hub, provided at one end with a lock for securing the
adjustable element of the bearing in its adjusted position, arranged according to the
first part of our invention, whilst the other and chain wheel end is provided with a
combined locking-ring and bearing cup screwing into an enlarged chamber of the
said hub in accordance with the second part of our invention.
Figure 2 is a longitudinal vertical section of Figure 1, taken upon the dotted
line x.
Figure 3 is an elevation of the chain wheel end of the hub and Figure 4 an
elevation of the bearing-adjustment end.
Figure 5 represents a longitudinal vertical section of the body of the hub,
separately.
Figure 6 shows an elevation, an edge view and a section of the combined lock-
ring and ball raced bearing cup separately.
Figure 7 represents like views of the adjusting cup and Figure 8 an elevation and
an edge view of its locking tongue.
Figure 9 represents the spindle of the hub, showing the enlarged cone at the
chain wheel end.

page_text: The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is an ordinary shell body part, comprising the waist a', spoke flanges ², and
head ends a, a, having mouths a, a, both of which are inside screwed, to take the
cups b and c, whilst the spindle d, which has 'ball-raced collars or cones d³, d², near
its two ends, directed axially therethrough. The adjustable she-coned ball race or
cup b, is outside screwed (preferably with a right hand thread) for taking into the
like inside screwed mouth at, of the head 3, to form an oil-retaining and dust-proof
cap and has a flanged edge 62, the periphery of which has a series of notches or
recesses 63, with which the free end e¹ of a spring tongue e, secured by a screw or like
means to a part of the hub casing engages and takes in one or other of the said
notches 63, between the teeth or projections 4, and thus holds the said adjusting cup
or disc in its adjusted position by preventing its rotation backwards or forwards
within the mouth of the hub.
+
An ordinary lock nut, such as f³, may take upon the screwed end d³, of the
spindle, and between it and the protruding end of the collar or cone, of the
spindle, the back fork jaws come or equivalent part of the framing of a bicycle may
and be there held by the screwing up of the said nut, although as an additional
precaution for preventing the rotation of the spindle, we may form flats on the said
spindle or upon the extended part of the cone which may be embraced by the said
fork end jaws.
By locking the inside coned cups or discs in their adjusted positions by means as
described, the same can be adjusted without interfering with the adjustment of the
chain and the chain can be adjusted without disturbing the adjustment of the hub
bearings.
In lieu of a spring tongue lock as shown, we may employ a catch, detent or
equivalent means for engaging with notched or equivalent formatious of the cup or
ball raced disc, and instead of the notched flange or circular rack being on the edge
of the cup, it may be formed on the edge of the hub ends and the spring, catch,
tongue or like locking device may be carried on the adjusting element, whilst
instead of the cones or discs being adjusted and locked at one end of the hub only
they may be adjusted and locked at both ends.
This part of our invention is applicable to the locking of the adjustable elements
of hubs of the "cone" and "cup" pattern, also to bottom bracket and pedal bearings
its application to these forms differing in no essential respect from its application to
a disc-adjusting hub as described.
The combined chain wheel lock nut and bearing cone or cup f, consists of a large
disc or circular plate f, having at the middle of its inner side f, a she coned cup f³,
forming an inside ball race f, and being outside (preferably left-hand) screwed at f,
to take into the interiorly and correspondingly wormed and enlarged mouth a³ of
the head a, at the chain wheel end of the hub, the said head being outside and
preferably right-hand screwed to take the chain wheel g, which is locked by the
plate or dise end of the cone jambing against its opposed face g¹. Figure 10
represents a modification of the first part of my invention, in which the end e¹, of a
sliding bolt, engages with the notches 63, of the adjustment clip b.
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 Locking the adjustable elements of the bearings of wheel hubs and cycle
bottom brackets and pedals in their adjusted positions, by a tongue spring, catch,
detent or equivalent carried by a relatively fixed part or element of the bearing,
engaging in or between notches, teeth, projections or equivalent formations on the
adjustable element, substantially as described and set forth.
Secondly-The modification of the locking means referred to in the first claim, in
which the locking tongue, catch or equivalent is carried by the adjustable element

page_text: of the bearing and engages with notches or equivalent formations on a fixed part or
element, substantially as described.
Thirdly-A combined chain-wheel-locking ring or nut and bearing cup for wheel
hubs, substantially as and for the purpose herein described and set forth.
