WC, PERCY HARGREAVES, of 15, Preston New Road, Blackburn, in the County
of Lancaster, Draper's Assistant, and MARY HARGREAVES, of 14, Altom Street,
Blackburn aforesaid, Draper's Assistant, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the manufacture of the ball bearings
of cycles the object being to so construct the hubs that the ball bearings of the
latter are automatically adjusted and kept in position after being set or regulated,
and the hub and wheel assume a correct and central position between the forks
of the frame. When the invention is applied to the pedals as hereinafter described
there is no liability of the crank and pedal becoming loose or detached and the
pedal can be removed from the pedal pin without the balls, cones, or cups being
deranged. The invention also relates to improved lubricating devices whereby
the bearings or wearing surfaces can readily be lubricated and access thereto
of dust or dirt prevented, and the parts of each device being connected together
there is no danger of losing any of them.
According to this invention the hub, cups, and cones are made somewhat
similar to the ordinary ones, the axle passing through the centre of the hub, and
on one end of the axle is fixed a cone, the cone on the opposite end of the axle
being free to move to and fro on a longitudinal key formed on the axle. Between
the fixed cone and the movable one and around the axle is a spiral spring which
tends to force the movable cone outwards and so to keep the balls, cones, and cup
in correct relative positions. On the axle and outside the hub is a nut by which
the position of the movable cone can be adjusted. The forks instead of being
fixed to the axle as heretofore are connected to elongated square or angular por-
tions of the cones and fixed thereto by nuts.
When the improvements are applied to the pedals, the pedal pin has a chased
boss at one end, and the outer end of the pin is first passed through the eye in
the crank and the chased boss is screwed into the eye which is tapped and has an
inner flange or shoulder to prevent the crank being turned beyond a given point
and also to effectively prevent the pedal pin working loose and becoming detached
from the crank.
On the pedal pin are placed the usual cones and on the barrel the ordinary cups,
the cone at the inner end of the pin being held in position by means of a key
on the pedal pin and by means of projections hereinafter referred to. The
cone on the outer or opposite end to the crank is free to move to and fro longitudin-,
ally on the key on the pedal pin, and is forced outwards by means of a spiral
spring as above described.
In order to prevent the inner cone moving round on the pin, or the pin moving
round in the crank, there are a series of keys or projections on such cone and
these are received in corresponding recesses formed in the crank.
On the pedal pin may be placed a tube or shell, one end being fixed to the
inner cone, the opposite end carrying the outer cone. The tube or shell is held

page_text: in position on the pedal pin by means of a headed screw or nut screwed into the
end of the pedal pin. The position of the outer cone is regulated by means of a
nut on the tube or pedal pin. When this tube is employed the pedal can be
removed from its pin without deranging the balls or cones.
The lubricating device consists of a covered cap with hole or channel com-
municating from the lower part with the part to be lubricated and in the top or
cover of the cap is another hole. The cup is covered with a screwed cap in
which is a hole, and by unscrewing the cap the holes in the cup and cap become
linable and lubricant can be inserted. When the cap is screwed up the holes
are closed and the cap being tightly screwed down prevents access of dust. In-
stead of the cap being screwed the inside of the cup may be provided with a
screwed shell, and by means of a projecting pin the shell can be turned until the
hcles are opposite one another. By screwing the cap or cover or cup instead of
simply turning it as heretofore, the cap and cup are brought tightly into con-
tact and the holes hermetically closed. Stop pins may be employed to limit the
amount of movement of the cap, or cover, or cup.

We, PERCY HARGREAVES, of 15, Preston New Road, Blackburn, in the County
of Lancaster, Draper's Assistant, and MARY HARGREAVES, late of 14, Altom
Street, Blackburn aforesaid, and now of 3, King Street, Clitheroe, in the County
of Lancaster, Spinster, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
1
This invention relates to improvements in the manufacture and arrangement
of the ball bearings of the hubs, bottom brackets, and pedals of cycles, the object
being to facilitate the adjustment of the bearings and to ensure the latter being
maintained in the requisite position when so adjusted and set, and to allow of
the tension of the chain being regulated without liability of disturbing the
adjustment of the bearings of the rear hub. When the invention is applied to
the pedals there is no liability of the pedal becoming loose or detached from the
crank; at the same time the pedal can be removed from the pedal pin without
the balls, cones, or cups being deranged.
Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the annexed drawings, in
which:-
.
Fig. 1 is a sectional elevation of the improvements as applied to the hub of a
cycle, the axle cones being directed inwards.
Fig. 2 is a similar view to Fig. 1 but shewing the improvements applied to the
front wheel hub and with the axle cones directed outwards, i.c., in a reverse
direction to the ones shewn by Fig. 1.
Fig. 3 is a sectional elevation of the improvements as applied to the pedals of
cycles.

ments applied thereto.

page_text: According to this invention and referring to Figs. 1 and 2, the hub 1, cups 2,
and cones 34 are made somewhat similar to the ordinary ones, the axle 5 pass-
ing through the centre of the hub 1, and on one end of the axle 5 is fixed a cone 3,
the cone 4 being free to move to and fro longitudinally on the opposite end of
the axle 5. Between the fixed cone 3 and the movable one 4 and around the
axle 5 is a spiral spring 6ª which tends to force the movable cone 4 outwards.
On the axle 5 and outside the hub 1 is a lock-nut 8 by which the position of the
movable cone 4 can be adjusted. The fork instead of being fixed to the axle 5
as heretofore, is connected to elongated square or angular portions 9 of the cone 4
and fixed thereon by nut 6 which prevents rotation of the cone 4.
The method of adjustment will be clearly seen on reference to Fig. 2 wherein
the axle 5 is shewn with the locking and adjusting nut 8 thereon. By turning
this nut in one or other direction the positions of the cones and balls is deter-
mined and adjusted and the spring 6" maintains the same in such position.
When the improvements are applied to the pedals (sec Sheet 3) the pedal pin 1
has a chased boss at one end, and the outer end of the pin 1 is first passed through
the eye 3 in the crank 4, and the chased boss 2 is then screwed into the eye 3
which is tapped and has an inner flange or shoulder 5 to prevent the pin 1 being
turned beyond a given point and also to effectively prevent the pedal pin 1 work-
ing loose and becoming detached from the crank 4.
On the pedal pin 1 are placed the usual cones 6-6, and in or forming part of
the barrel 7, the ordinary cups S-8, the cone 6 at the inner end of the pin 1
being held in position by means of slots 8 in the crank 4 and projections 9 on
the cone 6. The cone 6 on the outer or opposite end to the crank 4 is free to
move to and fro longitudinally on the key 10 on the pedal pin 1 and is forced
outwards by means of a spiral spring 11 as above described in reference to Figs. 1
and 2.
In order to prevent the inner cone 6 moving round on the pin 1, or the pin
moving round in the crank 4, the inner cone 6 is on a key or flat surface on the
pin 1, and there is or are one or a series of keys or projections 9 on such cone 6,
and these are received in corresponding recesses or key slots 8ª formed in the
crank 4 (see Figs. 5 and 6).
On the pedal pin 1 may be placed a tube or shell 12, one end being fixed to the
inner cone 6, the opposite end carrying the outer cone 6 on a key. The tube or
shell 12 is held in position on the pedal pin by means of a nut 13 screwed on the
end of the pedal pin 1. The position of the outer cone is regulated by means of
a nut 14 on the tube 12. The cones 6--6 may be reversed, that is, directed out-
wards, if desired.
Referring to Fig. 7 illustrating a bottom bracket, the adjusting cone 4 is free
to slide on a longitudinal key or flat place 4" on the axle 5. The cone 4 is pro-
vided with an external thread on the outer end, and the adjusting nut 8 engages
with the thread on the cone 4, the nut 8 and cone 4 being held tight against the
crank or a projection on the axle 5 by means of the spiral spring 6. The nut S
is provided with a hexagonal or milled surface 8 for the purpose of adjustment,
and by turning the nut S the cone 4 moves inwards or outwards whilst the nut
retains its position against the crank owing to the pressure of the spring 6ª. The
axle or spindle 5 of the crank or of the hub 1 may be formed with a shoulder or
collar 10 (see Fig. 7) against which the spring C bears, and by this arrangement
a shorter spring may be used.
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:-
(1) The general construction, arrangement, and combination of parts con-
stituting the improved cycle hub bearings as and for the purpose herein described
and substantially as illustrated by Figs. 1 and 2 of the annexed drawings.
(2) The general construction, arrangement, and combination of parts con-
