Improvements in the Construction of Bearings for Cycles and
other Vehicles.
We, HARRY WALKER, TOM WALKER, and SAMUEL GOLDTHORPE, trading as Walker
Brothers, all of Primo Works, Meanwood Road, in the City of Leeds, Cycle
Engineers, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved device for locking and adjusting the cones,
cups, or discs, in bearings for the hubs, crauk brackets, pedals, or other parts of
cycles or other vehicles.
We employ two cones, cups, or discs, having respectively right and left hand
threads, and connected by a central sleeve threaded either internally or externally,
so forming a complete bearing in itself. This bearing has, when fitted together, a
plain surface, so as to slide into the hub, crank bracket, or pedal barrel, which is
bored or otherwise made plain to receive it.
A thin plate or bracket, having a pin at each end and a central transverse slot is
fitted longitudinally to the outside of the hub, crank bracket, or pedal barrel.
These pins pass through holes in the hub, crank bracket, or barrel and engage in
slots or recesses in the cones, cups, or discs, thus preventing the cones, cups, or
discs, being turned round and so worked in or out by the friction of the bearing.
Or in lieu of these pins the cones may be secured by keys driven from the ends
of the bearing.
To prevent lateral motion of the bearing in the hub, crank bracket, or pedal
barrel, we employ a stud or screw, which is passed through the slot in the loose
plate or bracket and a corresponding slot in the hub, crank bracket, or pedal barrel,
and which screws into a hole or recess in the central inner sleeve.
To adjust the bearing and prevent slackness due to wear and tear, the stud or
screw may be slackened and moved along the transverse slots in the loose plate or
bracket and in the hub, crank bracket, or pedal barrel.
This movement slightly turns the certral inner sleeve into which the cones
engage, and as the cones are prevented from turning by the pins or keys, and have
right and left hand threads, it tightens or slackens the bearing as required.
When applying our invention to pedals, as the barrel can be slid off the bearing
itself, either a rubber, or rat trap, a wide, or narrow pedal may be fitted, and be
interchangeable at will, without in any way interfering with the bearing, or neces-
sitating the said bearing being removed from the machine.

We, HARRY WALKER, TOM WALKER, and SAMUEL GOLDTHORPE, trading as Walker
Brothers, all of Primo Works, Meanwood Road, in the City of Leeds, Cycle
Engineers, 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 :-
The object of our invention is to provide an improved device for locking and
adjusting the cones, cups, or discs in bearings for the hubs, crank brackets, pedals,
or other parts of cycles or other vehicles.
adjusting the cones, cups, or discs in bearings for the hubs, crank brackets, pedals,
or other parts of cycles or other vehicles.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation of our invention as applied to the hub of the rear
or driving wheel of a bicycle.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is an end view showing the application of our invention to the crank
bearing bracket of a bicycle.
Fig. 4 shows the crank axle bearing, complete in itself and removed from the
crank bracket.
Similar letters are employed to indicate similar parts in all the figures.
We employ two cones, cups, or discs A, having respectively right and left hand
threads, and connected by a central sleeve B threaded either internally or externally,
so forming a complete bearing in itself (see Fig. 4). The bearing 80 formed has a
plain surface, so as to slide into the hub C, bracket D, pedal barrel, or the like part,
which is bored plain to receive it.
A thin plate or bracket E, having a pin F at each end and a central transverso
slot G, is fitted longitudinally to the outside of the hab C, crank bracket D, or the
like. The said pins F pass through holes in the hub C, crank bracket D, or the
like, and engage in slots or recesses H in the cones, cups, or discs A, thus pre-
venting the said cones, cups, or discs from turning round. Or in lieu of these
pins F the cones A may be secured by means of set screws, or by keys driven from
the ends of the bearing.
To prevent lateral motion of the bearing in the hub C, bracket D, or the like,
we employ a stud or screw K, which is passed through the aforesaid slot G in the
plate or bracket E and a corresponding slot in the casing of the hub C, crank
bracket D, or the like, and which screws into a hole or recess L in the central
sleeve B.
To adjust the bearing and prevent slackness due to wear and tear the said stud or
screw K is loosened and moved along the transverse slot G. This movement
slightly turns the central sleeve B into which the cones A engage, and as the said
cones are prevented from turning and have respectively right and left hand
threads, the bearing is slackened or tightened according as the movement of the
stud or screw K is forward or backward. The entire adjustment and locking of
the bearings is consequently controlled by the stud or screw K, which may itself
be provided, if necessary, with any suitable locking device.
When our invention is applied to pedals the barrel can be slid off the bearing
itself, and consequently any pattern or size of pedal may be fitted and be inter-
changeable at will, without in any way interfering with the bearing or necessitating
its removal from the machine.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a bearing for the hubs, crank brackets, pedals, or other parts of cycles and
other vehicles, the employment of cones, cups, or discs screwed with opposite
threads and connected to a central sleeve with corresponding threads, forming a
bearing complete in itself so as to be removable from the casing of the hub,
bracket, pedal, or other part to which the bearing is applied.
2. In a bearing for cycles and other vehicles, the employment of the removable
bearing as described in the foregoing claim, locked and adjusted within the casing
by means of an external plate or bracket having pins passing through the casing
and engaging with longitudinal slots or recesses in the cones, and a central stud or
screw passing through a transverse slot in the external plate and in the casing and
engaging with the central sleeve of the bearing, substantially as shown and
described.
3. In a bearing for cycles and other vehicles, the combination with the hub
casing C, crank bracket D, or pedal barrel, of the cones A screwed with opposite
threads to the sleeve B, the plate or bracket E with locking pins F or the like, and
the adjusting stud or screw K engaging with the sleeve B and passing through a
transverse slot G in the plate E and in the casing C or the like, substantially as
and for the purposes shown and described.
Dated this 2nd day of July 1898.
