PROVISIONAL SPECIFICATION.
Improvements in Bicycles, Tricycles, and other Velocipedes.
I, ANDREW WILLIAM STOREY, of No. 13 York Road, Erdington, in the County
of Warwick Mechanical Engineer do hereby declare the nature of this Inven-
tion to be as follows:-
My invention relates to the locking of the adjustable parts of the ball bearings
of bicycles, tricycles and other velocipedes and has for its principal object to sim-
plify the construction and arrangement of parts for that purpose.
I will describe my invention with reference to the locking of the ball cup of
the hub of one of the wheels of a velocipede.
I prefer to apply my invention to the left hand end only of the hub and I will
describe it in connection with the left hand end although it may be applied to the
right hand end as well as to the left hand end or to the right hand end only.
I make the ball bearing cup smaller at its outer end than at its inner end or
part which takes into the hub and I form on the said smaller end flats by which
the ball bearing cup may be readily turned to effect its adjustment. I make the
screw thread on the larger part of the said cup and the internal screw thread in
the end of the hub into which the cup takes left handed. I form on the exterior
of the end of the hub a right handed screw thread and on this I screw a locking
ring constructed as follows.
The said locking ring has a nearly U or trough shaped figure in cross section
the open side of the trough being at that side of the ring which is presented
to the end of the hub in screwing it in place on the said hub. The outer part or
rim of the ring is screw threaded internally the said internal screw thread engaging
with the right hand thread on the end of the hub when the said locking ring is in
place. The flat edge of the inner part of the ring bears when the locking ring is
screwed home against the outer side or marginal part of the adjustable ball bear-
ing cup and by frictional contact therewith locks it in the position to which it
has been adjusted.
The flatted smaller part of the ball bearing cup projects slightly through the
locking ring so that when it is desired to re-adjust the position of the cup it is
only necessary to slightly unscrew the locking ring when the ball bearing cup
may be turned through a small angle in one or other direction without wholly
removing the locking ring, by means of a spanner the locking ring being screwed
home for fixing the part in its re-adjusted position.
Although I have only described my invention in connection with the locking
of the adjustable part of one of the ball bearing arrangements of the hub of a
velocipede wheel yet I wish it to be understood that it is applicable to the locking
of the adjustable part of the ball bearing arangements of the crank axle or bottom
bracket bearing as well as the ball bearings of pedals and other ball bearings, such
for example as ball head bearings.

page_text: I, ANDREW WILLIAM STOREY, of No. 13 York Road, Erdington, in the County
of Warwick, Mechanical Engineer, do hereby declare the nature of my 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 relates to the locking of the adjustable parts of the ball bearings
of bicycles tricycles and other velocipedes and has for its principal object to sim-
plify the construction and arrangement of parts for that purpose.
I will describe my invention with reference to the locking of the ball cup of
the hub of one of the wheels of a velocipede.
I prefer to apply my invention to the left hand end only of the hub and I will
describe it in connection with the left hand end although it may be applied to the
right hand end as well as to the left hand end or to the right hand end only.
I make the ball bearing cup smaller at its outer end than at its inner end or
part which takes into the hub and I form on the said smaller end flats by which
the ball bearing cup may be readily turned to effect its adjustment. I make the
screw thread on the larger part of the said cup and the internal screw thread in
the end of the hub into which the cup takes, left handed. I form on the exterior
of the end of the hub a right handed screw thread and on this I screw a locking
ring constructed as follows.
The said locking ring has a nearly Ụ or trough shaped figure in cross section
the open side of the trough being at that side of the ring which is presented
to the end of the hub in screwing it in place on the said hub. The outer part or
rim of the ring is screw threaded internally the said internal screw thread engaging
with the right hand thread on the end of the hub when the said locking ring is in
place. The flat edge of the inner part of the ring bears when the locking ring is
screwed home against the outer side or marginal part of the adjustable ball bear-
ing cup and by frictional contact therewith locks it in the position to which it
has been adjusted.
The flat sided smaller part of the ball bearing cup projects slightly through the
locking ring so that when it is desired to re-adjust the position of the cup it is
only necessary to slightly unscrew the locking ring when the ball bearing cup
may be turned through a small angle in one or other direction by means of a
spanner without wholly removing the locking ring, the locking ring being screwed
home for fixing the part in its re-adjusted position.
Figure 1 of the accompanying Drawing represents partly in elevation and partly
in section the hub and spindle of the back wheel of a safety bicycle to which the
ball cup locking mechanism constituting my invention is applied; Figure 2 repre-
sents the same in end elevation.
Figure 3 represents partly in elevation and partly in section the locking ring
separately and Figure 4 represents an elevation of the inner side of the same.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.

ing cup screwed into the left hand end of the hub a.
of the hub a is screw threaded both internally and externally, the internal screw
thread being preferably left handed and the external screw thread right handed.
The body part of the adjustable ball cup c is provided with a screw thread corres-
ponding to that of the internal screw thread of the mouth of the hub a into which
it is to be screwed the said cup being screwed into the hub by its smaller outer
end c, the flat faces or sides c¹, c' of which permit of the engagement of a spanner

The said locking
by the locking ring d shown separately in Figures 3 and 4.
ring d has the form of an annular trough the open side of which trough is pre-
sented to the end of the hub when the locking ring is to be screwed on the end
of the said hub. The edge of the outer or larger part of the trough or U shaped
ring d extends beyond the inner edge d and the said outer or larger part is screw
threaded internally so as to take on and fit the external screw thread on the end
of the hub a. When the said locking ring d is screwed home its inner edge d'
comes in contact with the outer face of the ball bearing cup cas is best seen in the
sectional part of Figure 1 and by frictional contact therewith prevents the turn-
ing and outward motion of the said cup c. The adjustable ball bearing cup c
is thus securely locked in position and the accidental disturbance of the adjust-
ment of the bearings prevented.
Although I have only represented my invention applied to the left hand end of
the hub a yet it may be applied to the right hand end instead of the left hand
end or to the right and left hand ends with the same or nearly the same effect.
When the ball cup locking mechanism constituting my invention is applied to
the right hand end of the hub I prefer to make the internal screw thread at the
right hand end of the hub and the screw thread of the ball cup to be inserted
therein right handed and the external screw thread at the said right hand end of
the hub and the screw thread of the locking ring to be used at the said right hand
end, left handed.
- The application of my invention to the locking of the adjustable parts of the
ball bearings of the crank axle and bottom bracket of a velocipede as well as the
ball bearings of pedals and other ball bearings such for example as ball head bearings
differs in no essential respect from its application to the locking of the adjustable
ball bearing cup at the left hand end of a velocipede wheel as hereinbefore described
and represented.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention of " Improvements in bicycles, tricycles, and other velocipedes
Locking the ball cups or adjustable parts of the ball bearings of velocipedes in
their adjusted position by screwing both internally and externally the ends of
the hubs or parts into which the cups or adjustable parts are to be screwed the
said internal and external screw threads being oppositely threaded, that is, one is
left handed and the other right handed and combining with the said hub or like
part and cup or adjustable part of the bearing a screwed locking ring of a U or
trough shaped figure in cross section the inner or flat edge of which ring when
screwed home on the external screw thread of the hub or like part comes in contact
with the outer side or face of the cup or adjustable part of the bearing and by fric-
tional contact therewith locks it in its adjusted position substantially as herein before
described and illustrated in the accompanying Drawing.
Dated the First day of November 1897.
