PROVISIONAL SPECIFICATION.
Improvements in connection with Bearings for Bicycles, Tricycles,
and other Velocipedes and Vehicles.
I JAMES WILLIAM FLAVELL, Elsdene, Wretham Road, Handsworth juxta
Birmingham in the County of Warwick, Manufacturer do hereby declare the
nature of this invention to be as follows:-
This invention has reference to an improved method for fixing or securing dust
caps on the ends of cycle hub, pedal and other vehicle hearings, the object of which,
is to materially lessen the cost of production of such dust caps.
For the purpose of carrying my invention into practice I form the dust cap.
out of sheet metal by means of suitable press tools. 1 then cut two or more Vor
other shaped slits at suitable distances apart in the flange or rim of the said dust
cap and raise a tit or lip on the portion between such slits which fit into a corre-
sponding recess or recesses formed in that portion of the bearing in which the dust
cap is inserted by which means the said dust cap is firmly secured on the end of
the bearing, the cost of production is materially lessened as the said dust cap can
be formed out of sheet metal by suitable press tools and no screwing or tapping is
required, at the same time it has a lighter and neater appearance.
I
may
Instead of cutting slits in the flange or rim of the said dust cap
if
desired either rivet or otherwise secure a flat steel spring. or equivalent on the
outside or inside of the said flange or rim which said spring is provided with one or
more tits or lips which take into the corresponding recess or recesses formed in
that portion of the bearing in which the said dust cap fits. Or I may secure a
suitable additional metal ring inside that portion of the bearing into which the
dust cap fits and provide the said additional metal ring with one or more tits or lips
which take into corresponding recesses formed on the flange or rim of the said
dust cap.
Or I may dispense with the additional metal ring and instead form a
recess around the periphery of the ordinary hardened bearing cup before the said
cup is inserted in the bearing. In this case one or more holes or recesses are formed
around the said recess for the corresponding tits or lips formed on the flange or rim
of the said dust cap to take into, or vice versa.

I, JAMES WILLIAM FLAVELL, First Avenue Hotel, London, Manufacturer,
late of Elsdene Wretham Road Handsworth in the County of Stafford, 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 an improved method for fixing or securing dust
caps on the ends of cycle hub, pedal and other vehicle bearings the object of which
is to materially reduce the cost of production of such dust caps.

page_text: In order that my invention may be clearly understood I have illustrated same on
the annexed sheet of drawings.
Fig. 1 shews the dust cap A which is formed out of sheet metal by suitable press
tools. The said dust cap A has two or more V or other shaped slits b cut at
suitable distances apart in the flange or rim and a tit or lip e raised on the portion
between such slits b. When the said dust cap A is inserted into the end of the
bearing B the tits or lips c fit into corresponding recesses d formed in the said
bearing B by which means it will easily be understood that the said dust cap A is
firmly secured in the end of the said bearing B.
Fig. 2 shews another method for securing the dust cap A into the end of a
bearing. In this case instead of cutting slits in the flange or rim of the said dust
cap AI rivet or otherwise secure a flat steel spring e or equivalent on the inside
or outside (but preferably on the inside as shewn) of the said flange or rim
and provide the ends of the said spring e with a tit or lip which take into
corresponding recesses formed in the end of the bearing into which the said dust.
cap A is inserted.
Fig. 3 shews another method of securing the dust cap A into a bearing. In this
case I have shewn my invention applied to a pedal bearing and I secure an
additional metal ring 9 inside the end of the bearing B provided with two or more
tits or lips h. The dust cap A is provided with a recess or groove i or equivalent
and when the said dust cap A is inserted in the end of the pedal bearing B the
tits or lips h formed on the additional metal ring g take into the said recess or
groove thereby firmly securing the said dust cap A in position. The additional
metal ring and dust cap A may be formed vice versa if desired. Or I may.
dispense with the additional metal ring g and instead form a recess ; as shewn at
Fig. 4, around the periphery of the ordinary hardened bearing cup k before the
said cup k is inserted in the hearing, one or more holes or recesses being formed
around the said recess j for the corresponding tits or lips / formed on the flange or
rim of the dust cap A to take into, or vice versa.
Although I have described and shewn my invention as applied to cycle hubs and
pedals it can with equal advantage be applied to other vehicle bearings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would have it understood
that I do not limit myself to the precise details as herein shewn and described as they
may be varied without departing from the nature of my invention but what I wish
to claim is —
Firstly. Securing a dust cap or equivalent on the end of a cycle hub, pedal
or other vehicle bearing by forming the rim or flange of such dust cap so as to
spring into its place or by the use of an independent spring or springs fixed either
inside or outside the said rim or flange in the manner substantially as herein shewn
and described.
Secondly. Forming dust caps for cycle hubs, pedals and other vehicle bearings
in the manner substantially as herein described and illustrated on the accompanying
drawings.
