Improvements in and relating to the Anti-frictional Bearing Parts of
Cycles and the like.
I, THOMAS JOSEPH KENNEDY, Secretary to the Balmoral Cycle Company, of
Bromsgrove Street, in the City of Birmingham, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the bearing parts of cycles and the like, and consists
in certain improvements in their construction and fitting which render them more
neat in appearance.
The principal object of the invention is to so arrange the locking devices of
the bearing with the adjustment means that the whole of the parts, when set up,
come flush within the outer surface of the part of the cycle to which they are
fitted.
To
For instance, ordinarily, the ends of the front wheel spindle are locked to the
lower extremities of the branches of the front fork by nuts which project from
and abut against the outsides of the said extremities. By this invention the out-
standing nuts are dispensed with and in their stead is used thin locking rings,
one of which is adapted to take onto each of the screwed ends of the spindle and
to be let into one of the fork extremities so as to lie flush with its outer face.
allow of this the said extremities are a little thicker than usual, which is advan-
tageous for the purpose of strength; the same being formed from lugs brazed
onto the tubular fork members. The locking ring is let into or rotates within
a circular recess within the fork extremities, and screws up tight the adjusting
cones of the bearings against the inside faces of the extremities in the ordinary
way; small holes being provided within the said locking rings for the purpose of
rotating them with a peg spanner. By so fitting the locking means of the bear-
ings all is flush with the outer surface of the forks which renders the appearance
very neat.
In the locking arrangement herein before described the ends of the spindle,
although not protruding, can be seen, but this may be prevented by forming an
inwardly extending shank upon the inner side of each of the locking rings,
which have an axially screwed hole within them, but not coming through to the
outer face of the locking rings, and which said shanks extend into clearances in
the adjustable cones adjacent to them in order to obtain sufficient screw threads
within the axis of the said collars to engage the spindle ends.
In applying the invention to a pedal the adjustable cone which traverses within
the ball race screwing upon the end of the pedal spindle is recessed or hollowed
out to accommodate a thin locking ring, which fits it and screws up tight against
the bottom of the said recess, or against a D shaped washer disposed between it
and the bottom of the recess. Holes are provided in the outer face of the locking
ring for the engagement of a peg spanner, and also slots upon the rim of the
adjustable cone adjacent in the recess, so that each of them can be turned. The
Price R71

page_text: chief point is that by recessing the cone and letting into it the locking ring the
whole of the parts come flush with the pedal end plate.
In applying the invention to the bottom bracket axis the adjustable cup, which
screws within its one end, is of such a length as to leave a number of threads
of the bottom bracket outside of it when it is adjustably screwed within the
bottom bracket bore, but an outstanding central collar is formed upon its outer
face to come flush with the outer end of the bracket, and within which holes are
made for a peg spanner. The locking ring is centrally pierced to loosely fit
over the collar, as aforesaid, and screws into the bore of the end of the bottom
bracket up against the side of the adjustable ball race, against which it impinges
for the purpose of locking; holes being provided within the said ring for the
engagement of a peg spanner. By letting the locking ring as it were into the
adjustable cone or into the bore of the bottom bracket all parts of the bearing
are flush with the bottom bracket end which, as before stated, is the primary
object of the invention.

Improvements in and relating to the Anti-frictional Bearing Parts of
Cycles and the like.
I, THOMAS JOSEPH KENNEDY, Secretary to the Balmoral Cycle Company, of
Bromsgrove Street, in the City of Birmingham, 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 has reference to the bearing parts of cycles and such like and
consists in certain improvements in their construction and fitting which, whilst
increasing their rigidity and strength, render them infinitely more neat in their
appearance, especially when applied to bearing parts which have connected to
them parts of a cycle's, or the like's, stationary frame work.
The principal object of the invention is to so arrange the locking devices of
the bearing with the adjustment means that the whole of the parts when set up
in connection with a cycles frame come flush with the outer surface of that part
of the said frame to which they are fitted. For example; ordinarily, the ends of
the spindle of the front wheel of a cycle are connected to the lower extremities
of the branches of the front fork by screw nuts which take onto the spindle ends
and which project from and abut against the outsides of the said extremities.
Now by this invention these outstanding nuts, which are an undoubted drawback
to a machine's finish, are dispensed with and in their stead is used thin locking
rings, one of which is adapted to take onto each of the spindle's screwed ends
and to be let or recessed into one of the fork's extremities so as to lie flush with its
outer face, and also so as to constitute the bearing pieces to each of the said
spindle ends within the fork extremities. To allow of this the said extremities
are formed a little thicker than usual, (which is advantageous for the purpose
of strength) the same being formed from suitable lugs brazed into the ends of
the tubular fork members. The locking rings, as aforesaid, have small holes
upon their outer faces for being laid hold of by a peg spanner for being rotated,
and each pulls one of the cones of the bearing tight up so as to lock them, in

page_text: the ordinary way, by jamming them against the inside faces of the forks
extremities.
This invention is particularly applicable to the attachment of the front wheel
of a cycle to the front fork, but it can also be applied with advantage to parts
of the bearings of pedals, and also as a neat pulling up means to the steering ball
head clip.
In order to clearly set forth this invention's practicability, and to aid in its
being clearly understood, annexed herewith is a sheet of drawings showing several
useful cycle purposes to which it can be applied. In the said sheet, Figs. 1,
2 and 3 show its application to the front wheel hub and the lower extremities
of the front fork of a cycle; the first fig. showing a side elevation of a greater
part of the front fork with the invention applied on its extremity, Fig. 2 a section
through both the front fork extremities and through portions of the bearing
parts of the front wheel hub, and Fig. 3 the parts of the one side of Fig. 2
separate.
In these figs. a are the branches of the front fork, and a their lower termina-
tions which are formed of solid parts brazed to the said branches. The termina-
tions are drilled or bored out horizontal, and in a cross direction, to two
diameters a³, as, the former being an all through hole, and the latter a sinking
or a recess of a larger diameter than the said hole and being formed upon the
outer side a of the said terminations. The bottom of the sinking or recess a
may be either coned as shown, or flat. c is the spindle of the front wheel hub,
and the screwed ends thereof, whilst d, d, are, respectively, the fixed and
adjustable cones of the bearing, each being formed on their outer faces with set
back axial clearances, ³, and with axial all-through screwed holes d'. The
screwed hole d is not absolutely necessary in the cone d, as this is a fixture
upon the spindle and may be in one piece therewith, the form shown being only
the one most convenient. The cone is the adjustable one of the bearings,
and it can travel upon its particular screwed end of the spindle or axis c.
e are the rings for locking the adjustment of the bearings and connecting the
ends of the spindle c to the branches a of the fork, and each takes the form of a
rotating part comprising a circular head and an internally screwed central
shank, and each is so formed that its head fits one of the recesses a¹ within
the terminations a² of the fork so as to come flush with the latter's outer side,
and its shank loosely fits one of the all-through holes a³ thereof and also one of
the clearances d³ in the cones. The internal screwed hole in the shank e³ of
each ring extends only a short distance into the head e², and does not come through
to the outer face of the head of the ring, so that the ends c² of the spindle care
not visible.
Small holes et are formed in the heads e² of the rings, e, for the engagement
of a peg spanner for screwing up.
In Fig. 2 the positions of the parts when the adjustment of the bearing is
locked and the ends of the spindles connected to the extremities of the forks are
clearly shown, the hub of the front wheel in this view being indicated by dotted
lines. It will be noticed that the screwed shanks e3 of the rings e do not abut
against the bottoms of the clearances d³ in the cones, as they are only let there-
into in order to obtain an extended screw connection between the ends of the
spindle and the rings e; furthermore, that the rings e form bearing pieces to
the spindle ends within the terminations a², and entirely prevents any chance of
damaging the threads of the screw as is often the case by their naked engage-
ment in the holes of the terminations.
In Fig. 4 a slight modification of the form of this invention Figs. 1 to 3
is shown, the side of the bearing shown being the one with the adjustable cone.
In this form the locking ring e is simply a thick disc (without a shank) which
screws onto the end of the spindle, the latter in this case being visible in line
only upon the exterior face of the terminations of the fork. The cone in this

page_text: form is of ordinary construction, that is to say, it is not formed with a sunken
clearance in its outer face.
In Fig. 5 the invention is shown applied to the outer part of the bearings of a
pedal. In this case the adjustable cone is recessed at a for the purpose of
letting the locking ring e lie within it so as to be flush with the outer face of
the pedal's end plate g. A washer e intervenes between the bottom of the
recess in the cone and the locking ring e, and the outer edge of the cone d³
is formed with cut-away parts, or with a milling, for rotating the said cone; other
than this the locking of the bearing's adjustment is the same as previously
described.
In Fig. 6 part of the invention is shown applied to the split clip of a cycle's
steering head, which effectually removes all outstanding parts of the pulling up
cross bolt and renders the said clip much more neat in appearance. In this fig.
the locking ring e is of the same form as in Figs. 1 to 3 and constitutes a pulling
up nut to the bolt.
It will be obvious from the drawings that by this invention certain parts of
cycles can be rendered much more neat in appearance, and, in certain cases,
strengthened and improved in their fitting without increasing the expense of
the cycle's manufacture.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is:-
First. Attaching the ends of a cycle wheel's spindle to the stationary frame
parts supporting them, or being supported by them, and locking the cones of
the wheel's bearing upon the said spindle's ends by screwed locking rings which
take onto the said spindle's ends and which are recessed or let into the said
frame parts so as to lie flush with the outer face thereof, and which are adapted
to form bearing pieces to the said spindle's ends and to be operated by a peg
spanner, substantially as described and set forth..
Second. In combination in a cycle's front wheel and front fork supported by.
it, branch terminations a² formed with axial holes a³ and sinkings or recesses a³,
bearing cones d, d, having clearances and screwed holes d' within them,
and which take onto the front wheel spindle c, and locking rings e which have
internally screwed shanks e as part of them and which take and fit within the
parts a³, a, of the terminations and the parts of the cones so as to lie Aush
to the terminations outer surface, and which are adapted to engage the ends c³
of the spindle and be operated by a peg spanner, substantially as described.
Third. In cycle pedals, the means for locking the adjustable cone of the bearing
within the pedal's end plate so that the whole of the parts come flush with the
latter, substantially as described with reference to Fig. 5.
Fourth. In split clips, for ball-heads, such as shown in Fig. 6, the means
described for pulling up the cross bolt and closing the clip, substantially as set
forth.
