I, JOHN KEMP STARLEY, of the Meteor Works, Coventry, in the county of
Warwick, Velocipede Manufacturer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN ROLLER BEARINGS, SPECIALLY APPLICABLE TO VELOCIPEDES
OR LIKE WHEELED CARRIAGES" to be as follows:-
My invention has for its object improvements in roller bearings, which bearings
may be especially used for velocipedes or carriages or for machinery generally to
which such bearings may be applicable.
My invention consists in an angular adjustable roller bearing so constructed that
the bearing surface (or surfaces) run on angular rollers and take a different position
on the inclined plane of the rollers in order to adjust the bearing.
In applying my invention to the small wheel of a velocipede wherein a hub runs
on a fixed spindle I mount the said angular rollers in a groove or grooves in collars
adjustable on the spindle and I form rounded, curved, pointed, or other suitable
surfaces on the hub so that a point or portion of such surfaces bears on the said
angular rollers which thus form an inclined plane or surface for the said point or
portion to adjust itself on, thus taking up a different position on the said rollers as
the bearing is set up.
Instead of the rollers running in collars on the spindle they may run in grooves
in the hub and the bearing surfaces before described be on the collars on the
spindle.
It will readily be understood that the details of the invention must be varied to
suit the class of bearing required.

I, JOHN KEMP STARLEY, of the Meteor Works, Coventry, in the county of
Warwick, Velocipede Manufacturer, 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
My invention has for its object improvements in roller bearings which bearings
may be especially used for velocipedes or carriages or for machinery generally to
which such bearings may be applicable.
My invention consists in an angular adjustable roller bearing so constructed that
a small frictional surface (or surfaces) bears on angular rollers and takes a different
'position on the inclined plane of the rollers in order to adjust the bearing.
In the drawings accompanying this specification I show vertical sections 'of
various modifications of bearings suitable for velocipedes.
Fig. 1 is a bicycle front fork bearing.
Fig. 2 a hub or back or front wheel bearing.
Fig. 3 bearing for a long axle such for instance as a balance.geared axle.
Fig. 4. a pedal bearing.
Fig. 5. modification of bearing surface.
Referring to Fig. 1. A is the fork having secured to it by screw or otherwise the
bearing case B.
C is a rounded surface formed thereon. D is a cap screwing into case B with a
corresponding rounded surface C¹. E is a collar or boss secured to the spindle F in
any suitable manner such as by a key also securing the crank G or otherwise.
if
E carries annular oppositely inclined grooves H, H¹ in which run angular
rollers I, I whose,peripheries bear on the surfaces C, C. before referred to. Now
cap D be screwed into case B the curved surfaces C, C¹ are necessarily obliged to
move on the faces of 'the angular rollers H, H' and so adjust the bearing. The
mere details of the bearing such as dust caps, locking devices, etc., may be varied
at will and I do not bind myself to use the exact details shown.
In Fig. 2, A, Aare the forks, B¹ the hub, C2, C3 the rounded surfaces thereon,
E, E collars on the spindle F¹ screwed thereon on threads L, -L¹.
The spindle F¹ is held in the forks A1, A2 by nuts K, K₁ and thread L screwing
into fork A¹ or in any other suitable manner and of course does not revolve; the
hub B running thereon. H, H³ are the angular grooves in the collars E, E²
and I, I³ the sets of rollers converging as shewn. The faces of the rollers form
converging inclined planes or surfaces for the said points or portions C³, C³ to
adjust themselves on and so take up a different position on the said rollers as the
bearing is set up by adjusting the collars E¹, E' on the spindle F¹.
The adjustment can be effected in any desired manner as for instance by turning
the collars E¹, E by inserting a pin or key in holes M, M¹ and locking the collars
when adjusted by lock-nut N and locking piece N¹, N being loose and N¹ attached
to the collar E and squarely or otherwise so shaped as to fit a recess in the fork
end A (as shewn) to prevent the collar E' running up.

page_text: I do not however confine myself to any particular means of adjusting the
collars.
Instead of the rollers running in the collars E, E' on the spindle I may forin
grooves corresponding to H2, H³ in the hub B¹ and form the bearing surfaces C2, C³
on the collars E, E' and adjust the latter on the spindle so that they bear on the
faces of the rollers carried in the grooves in the hub.
The pedal bearing Fig. 4 will be readily understood from the foregoing, E³ being
the collar on fixed spindle F. H' the groove. I* the rollers. 0 the surfaces on
pedal plate B
In Fig. 3. D' is a cap screwing into the fixed cross tube or support B³. C5 is
one rounded surface formed on a collar or ring D² to fit cap D¹ which is stepped as
shown so as to get the rollers in place. A set-screw, screws or other device
keeping collar or ring D2 in position. C is the other rounded or bearing surface
formed on D. E the collar fixed on spindle F³ which revolves. H³, H6 the
grooves in the collar E. 1, 1 the rollers."
Screwing up D¹ together with the ring or collar D' adjusts the rollers and
nut N2 can lock D¹ in position or I may have this cap D¹ a fixture; and by means
of a screw, slide or otherwise adjust collar E on spindle F³ to set up the
bearing.
In place of rounded surfaces C, etc., I may form them as more or less sharp or
blunt points as shown in Fig. 5 but always so that they only touch a portion and
not the entire surface of the roller and so take different bearings thereon by
adjustment.
I have not shown drawings of my arrangement of bearings in its application
to carriages and like vehicles otherwise than velocipedes or to other mechanical
purposes to which this form of bearing is or may be rendered applicable as the
details may be varied for individual instances or purposes but the principle of a
small rounded surface or point to take varying bearing contacts on a portion of
the periphery of an angular roller must of course be adhered to.
The point of contact only being very small frictional surfaces are thereby
reduced.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The hereinbefore described bearing constructed and operating substantially as
and for the purposes described and illustrated in the accompanying drawings.
2. A roller bearing having small frictional surfaces or points of contact bearing
on the face of angular rollers and capable of varying the position of the points of
contact of such bearing surfaces on the inclined plane formed by the peripheries of
the angular rollers, in order to adjust the bearing as herein before described.
