PROVISIONAL SPECIFICATION
Improvements in and relating to Bearings of Velocipedes.
I, GEORGE LEONARD MORRIS, of 15, Wells Street, Gray's Inn Road, in the
Parish of St. Andrews Holborn, in the County of London, Cycle Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to ball bearings as used for the various parts of velocipedes,
and it consists of a device for making the adjustable cup of the bearing self-
locking, the object being to simplify the adjustment of such bearings.
In carrying my invention into practice, I form the back of the cup slightly
thicker than usual and through it I make a narrow saw-cut or groove extending
about half way through the cup from its circumference towards its centre, and I
then set the part outside the slit slightly inwards or outwards before it is hardened,
so that the screw threads on the split part are slightly out of truth with the threads
on the other part, the result being that when the cup is screwed into the part
adapted to receive it, the split part of the back of the cup has to spring slightly
which causes sufficient friction between the threads to effectually prevent the
cup turning of itself. If more secured locking is required I use a small pinching
screw adapted to expand or contract the width of the saw-cut or slit. This screw
may be either threaded into the outer part to the cup and impinge on the inner
part thereof, or it may be passed freely through the outer part thereof and screw
into the inner part thereof, as found most convenient.
As a modification the split part of the back of the cup may be slotted radially
and expanded transversely by means of a coned screw or its equivalent threaded
either into the slotted part of the cup or into the inner part thereof.

Another method of attaining the object of my invention it to cut a transverse
slot across the circumference of the cup and fit a loose piece in the said slot, the
said piece having screw threads to coincide with those on

cup.
under this loose piece a coned screw or its equivalent is threaded into the back of
the cup, so that the loose piece can be forced outwards to jam the cup in the part
in which it is threaded.

COMPLETE SPECIFICATION.
Improvements in and relating to Bearings of Velocipedes.
I, GEORGE LEONARD MORRIS, of 15 Wells Street, Gray's Inn Road, in the
Parish of St. Andrews Holborn, in the County of London, Cycle 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 relates to ball bearings as used for the various parts of velocipedes,

page_text: and it consists of a device for making the adjustable cup of the bearing self-
locking, the object being to simplify the adjustment of such bearings.
I attain this end in the manner shown by the accompanying drawing in
which :-
Figure 1 is a sectional view of a cup for a ball bearing constructed according to
my invention.
Figure 2 is a similar view showing a modification.
Figures 3 and 4 are views in section and elevation respectively showing another
form my invention may assume.
Figures 5 and 6 are similar views showing another modification, and
Figures 7 and 8 are similar views showing a further modification.
Throughout the views similar parts are marked with like letters of reference.
The back of the cup A is made slightly thicker than usual and through it is
made a narrow saw-cut or groove a extending about half way from its circum-
ference towards its centre. The part a' outside the saw-cut or groove a is then set
slightly inwards as shown by Figure 1 or outwards as shown by Figure 2-before
the cup is hardened-so that the screw threads on the part al are slightly out of
truth with the threads on the other part of the cup the result being that when the
cup is screwed into the part adapted to receive it, the part a¹ of the cup has to
spring slightly which causes sufficient friction between the threads to effectually
prevent the cup turning of itself.
If more secured locking is required I use a small pinching screw R adapted to
expand or contract the width of the saw-cut or slit a as shown by Figures 3 and 4.
This screw B may be either threaded into the part a' of the cup and impinge on
the other part thereof as shown by Figure 2, or it may pass freely through the
part a' and screw into the other part as found most convenient.
As a modification the part a¹ of the back of the cup may be slotted radially
and expanded transversely by means of a coned screw B or its equivalent as
shown by Figures 5 and 6.
In a further modification a transverse slot is cut across the circumference of the
cup A for a short distance and a loose piece A' is fitted in the said slot, the said
piece having screw threads to coincide with those on the cup. Immediately under
the loose piece A¹ is a coned screw B or its equivalent threaded into the back of
the cup, so that the loose piece A' can be forced outwards to jam the cup A in the
part in which it is threaded.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
1. The improvements in and relating to the bearings of velocipedes substantially
as and for the purpose hereinbefore set forth.
2. In a ball bearing, an adjustable cup having a saw-cut or groove such as a
enabling the back thereof to be set slightly out of truth, as and for the purpose
set forth.
3. In a cup for ball bearings, the combination of the saw-cut or groove a and of
the screw B, as and for the purpose set forth.
4. A cup for a ball bearing constructed arranged and adapted to operate as and
for the purpose herein before described with reference to Figures 1 and 2 of the
accompanying drawing.
5. A cup for a ball bearing, constructed, arranged and adapted to operate as and
for the purpose hereinbefore described with reference to Figures 3 and 4 of the
accompanying drawing.
6. A cup for a ball bearing, constructed, arranged and adapted to operate as
and for the purpose hereinbefore described with reference to Figures 5 and 6 of
the accompanying drawing.

page_text: 7. A cup for a ball bearing, constructed, arranged and adapted to operate asfand
for the purpose hereinbefore described with reference to Figures 7 and 8 of the
accompanying drawing.
