PROVISIONAL SPECIFICATION."
Improvements in Adjustments for Cycle and other Ball Bearings.
We, BENJAMIN SHAW ROBERTS, Cycle Manufacturer of 40, Bellefield Road,.
Winson Green, and WILLIAM MORTON, Manufacturer, of Albert Street,,
Birmingham, both in the County of Warwick, do hereby declare the nature of this
invention to be as follows:-
Our invention has reference to improved adjustments for use upon ball bearings
in connection with cycles, or other vehicles and machinery, being especially.
applicable to the adjustment of a cycle crank spindle bracket, and also for the hubs
of the wheels and for the socket heads, the objects of the invention being to
produce an adjustment which can be readily effected so that the wear of the
bearings can be taken up, and the bearings locked at any desired position.
In carrying our invention into effect when applying our adjustable device to a
crank bracket, we make a flange on each side of the bracket where the cup enters*
in, and we form upon the flange a number of serrations, holes, or grooves, either
upon its face or upon its edge, the whole of the serrations or grooves being arranged
at intervals of uniform pitch around the circumference so as to permit of a slight
movement of the bearing or the slackening of the bearing being taken up by
means of the locking of our bolt or clip pin into one of the holes, serrations, or
grooves. We form upon or attach to the cup when it. is threaded in the usual
manner for screwing into the boss of the bracket a projecting ear or boss-like arm
through which we pass a screwed pin, the end of the pin being made to enter the
locking holes when the head of the screw is turned, so that the bearing may be
tightened up and locked at any desired position, after the screw has been turned
round so as to bring the pin opposite to any desired hole, serration, or groove.
We sometimes make our locking pin to enter upon the upper edge or rim of the
flange or we make it to engage with the grooves, or roughened surfaces upon the
face of the same. Instead of employing a projecting boss or arm for carrying
the locking pin or bolt, we sometimes make a spring like tongue which carries the
locking pin upon it, the spring being arranged so that it can be readily removed
from any hole or groove when it is desired to adjust the bearing.
We apply our improved means of adjustment for use either with a cup or cone,
and for use upon the hub of the wheels, the socket head or any other part where it
is desired to take up the wear of a bearing, modifying the essential features as
herein before described to suit the particular application of our invention.

We, BENJAMIN SHAW ROBERTS, Cycle Manufacturer, of 40, Bellefield Road,
Winson Green, and WILLIAM MORTON, Manufacturer, of Albert Street,
Birmingham, both in the County of Warwick, 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 :-
Our invention has reference to improved adjustments for use upon ball bearings
in connection with cycles or other vehicles and machinery, being especially
applicable to the adjustment of a cycle crank spindle bracket, and also for the hubs
of the wheels and for the socket heads, the objects of the invention being to
produce an adjustment which can be readily effected so that the wear of the
bearings can be taken up, and the bearings locked at any desired position.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to,―
Figure 1 is a sectional elevation representing our improved ball bearing
adjustment as applied to the crank bracket of a cycle.
Figure 2 is a side or end view of the bracket and bearing adjustment, whilst
Figure 3 is a view of the end adjacent to the chain wheel.
Figure 4 is a section elevation illustrating our adjustment applied to the driving
wheel hub, whilst Figure 5 is a similar view illustrating the adjustment as applied
to the socket or steering head.
The same reference letters in the different views indicate the same parts.
:
In carrying our invention into effect when applying our adjustable device to a
crank bracket, we make a flange such as A A² on each side or end of the
bracket A where the ball cups B B¹ enter in, and we form upon the flange A¹ a
number of serrations, holes, or grooves, either upon its face or upon its edge, but
preferably the face as illustrated at Figure 2, the whole of the serrations or
grooves being arranged at intervals of uniform pitch around the circumference so
as to permit of a slight movement of the bearing or the slackening of the same
being taken up by means of the locking of a bolt or clip pin into one of the holes,
serrations or grooves. We form upon or attach to the cup when it is threaded in
the usual manner for screwing into the boss of the bracket a projecting ear or
boss-like arm through which we pass a screwed pin, the end of the pin being made
to enter the locking holes when the head of the screw is turned, so that the bearing
may be tightened up and locked at any desired position, after the screw has
been turned round so as to bring the pin opposite to any desired hole, serration or
groove.
We sometimes make our locking pin to enter upon the upper edge or rim of the
flange or we make it to engage with the grooves or roughened surfaces upon the
face of the same.
Instead of employing a projecting boss or arm for carrying the locking pin or
bolt, we sometimes make a spring like tongue such as C which carries the locking
pin D upon it, the spring being arranged so that it can be readily pulled out from
any hole or groove to the position shown by dotted lines at Figure 1, when it is
desired to adjust the bearings.
We apply our improved means of adjustment for use either with a cup or cone,
and for use upon the hub of the wheels as shown at Figure 4, or upon the socket or
steering head as shown at Figure 5, or any other part where it is desired to take
up the wear of a bearing, modifying the essential features hereinbefore described
to suit the particular application of our invention.
In the application to a socket or steering head as shown at Figure 5, we form

page_text: holes around the outer face of the cone E, and provide a spring locking pin such
as F for entering the same, the cone E being screwed upon the inner tube G.
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,
holes around the outer face of the cone E, and provide a spring locking pin such
as F for entering the same, the cone E being screwed upon the inner tube G.
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. The improved method of adjusting and locking ball bearings, substantially
as described.
2. In cycle and other ball bearings the combination of a screwed cup or cone
with a locking pin or bolt arranged to enter or engage with holes, serrations, or
grooves, substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
