I, JOHN KEMP STARLEY, of the Metcor Works, Coventry, in the county of
Warwick, Velocipede Manufacturer, do hereby declare the nature of any invention
for "IMPROVEMENTS IN ROLLER BEARINGS FOR VELOCIPEDES, CARRIAGES, OR LIKE
to be as follows:-*
LIGHT VEHICLES OR LIGHT MACHINERY
"
This invention has for its object improvements in roller bearings for bicycles,
tricycles, or like velocipedes or like wheel carriages, or light machinery.
It is designed to produce a further modification of an arrangement for which
I have recently applied for Provisional Protection.
My present invention, while retaining angular rollers, is designed to provide a
means of adjustment by forcing such bodily up the running surfaces instead of
altering the plane of their angular rotation.
In carrying out my invention I use angular or bevelled rollers having flattened
or slightly curved peripheries running on flat angular surfaces on the bearing case,
hub, or shaft, spindle, or pivot.
For a hub bearing I form a flat angular groove in a collar on the spindle or
shaft and a flat angular surface on the hub, or vice versa.
By setting up these surfaces by screw or otherwise the conical annular space in
which the rollers run is contracted, thus moving the rollers bodily instead of
altering their angle of inclination.
I may if desired use rollers of V-section in place of flat or bevelled section.

Improvements in Roller Bearings for Velocipedes, Carriages, or
like Light Vehicles or Light Machinery.
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 FOR VELOCIPEDES, CARRIAGES OR LIKE
LIGHT VEHICLES OR LIGHT MACHINERY to be as follows:-
"
This invention has for its object improvements in roller bearings for bicycles,
tricycles or like velocipedes and wheeled carriages or light machinery.
It is designed to produce a modification of an arrangement for which I have
recently applied for Letters Patent.
My present invention while retaining angular rollers is designed to provide a
means of adjustment by forcing such bodily up the running surfaces instead of
altering the plane of their angular rotation.
In carrying out my invention I use angular or bevelled rollers having flattened
or slightly curved peripheries running on flat angular surfaces on the bearing case,
hub or shaft spindle or pivot.
For a hub bearing I form a flat angular groove in a collar on the spindle or
shaft and a flat angular surface on the hub or vice versa.
By setting up these surfaces by screw or otherwise the conical annular space in
which the rollers run is contracted thus moving the rollers bodily instead of
altering their angle of inclination.
I may if desired use rollers of V section in place of flat or bevelled section.
And in order that my said invention may be understood and carried into
practical effect I have annexed to this specification the accompanying sheets of
drawings and now refer to the figures and letters of reference marked thereon.
Fig. 1. is a vertical section of a hub for a tricycle or bicycle back wheel fitted
with bearings constructed in accordance with my invention.
Fig. 2 vertical section of a pedal bearing so fitted.
Figs. 3 and 4 vertical part sections of hubs in which respectively two and three
rows of rollers are used in place of one.
Fig. 5. Sheet 2. Section of a long bearing for a sociable or like axle taken
through the balance gear.
Referring to Fig. 1. A. is the hub B. B. B. B. flat, angular or bevelled surfaces
formed in the same C is the spindle D. D¹ the forks supporting it, one end
screwing into D and being locked by nut or otherwise the other passing through
fork D a nut securing the same. On the spindle C are screwed collars E. E¹
having grooves provided with flat angular or bevelled surfaces F. F. F. F. formed
on the same or the grooves could be in the hub or corresponding part.
G. G. G. G are the rollers which may be slightly rounded on their peripheries so
as to work on the surfaces B. B. B. B. and F. F. F. F. or they may be flat on the
peripheries if desired.
To set up the bearing to compensate for wear or if the same is loose the
collars E. E are screwed up or forced up by other suitable means.

page_text: This forces the rollers G bodily up the surfaces B. B. B. B. on the hub so
adjusting the bearing.
In Fig. 2. the same letters are adopted as far as possible A¹ A² being the pedal
plates B. B. B. B. the surfaces formed thereon. C the pedal pin. E' E the collars
one being secured or keyed to the pin C. the other screwing up or capable of being
forced up, or both so arranged.
A lock nut secures one collar or if both collars are used lock nuts secure both.
In Figs. 3 and 4 the same letters apply as in figure 1. but more than one row of
rollers is used, one set running faster than the next. If a long roller were used it
would appear that one end would require to run faster than the other which is
impossible, but by making the roller in several parts or discs. this is virtually
effected.
This double triple or multiple row of rollers is particularly applicable for use in
a "sociable or other long or heavy bearing as will be well understood.
در
Referring to Fig. 5 where a triple row of rollers is shewn I is one collar fixed to
the through axle J of the balance gear. F the surface on the same. K is the
other collar or case screwing into the covering or supporting tube L B surface on
this collar G. G. G. and G. G. G the rollers M lock nut.
Setting up the collar K. forces the rollers up the inclined surfaces.
The application of my said invention to other vehicles and to light machinery is
not shewn on the accompanying drawings but will be well understood.
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
First. In bearings for velocipedes carriages or like light vehicles or light
machinery, the combination of a spindle, a collar formed thereon or therewith
provided with an angular groove or surface, such collar being capable of being
adjusted by screw or otherwise backward or forward on such spindle, rollers
placed at an angle or formed angularly or bevelled, and, angular surfaces on the
hub or corresponding part travelling on the spindle, the said rollers being so
arranged as to be capable by the adjustment of the said collers or the corresponding
surfaces of being forced bodily up or along the said angular surfaces to adjust the
bearings substantially as described.
Secondly. The improved bearings for velocipedes substantially as described and
illustrated in the accompanying drawings.
