The Bamboo Cycle Co. Ltd., Petit Street, Wolverhampton in the County of Stafford,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to bearings and is especially applicable to adjustable ball.
bearings, such as are commonly fitted to velocipedes and the like. Our invention.
has for its object improved means for locking the adjustment of such bearings;
and it consists essentially in an internally and externally screw threaded washer
which is adapted to engage with both the adjusting part (cup or cone) of the
bearing and the part (case or axle) of the bearing into or onto which the said
adjusting part screws for the adjusting purposes, and the external and internal
screw threads on which washer are of different pitches.
In carrying out our invention as applied to the cup adjusting hub or bottom)
bracket of a velocipede, we adapt the adjusting cup to screw further into the case
than usual. On the back of the cup is formed a projecting concentric sleeve of
comparatively small external diameter; and on the exterior of this sleeve is formed
screw thread of different, and preferably slower, pitch than that in the case,
and of either the same or opposite direction. A washer having suitable external and.
internal screw threads is adapted to be screwed both onto the sleeve of the cup and
into the part of the case which projects over it. The washer is screwed on to the
sleeve before screwing the cup into the case and both are rotated together until.
the bearing is adjusted to the right degree when the washer is turned further
forward or a little backward until it jams and so locks the cup and case, and hence
the bearing. The cup and washer are provided with pin holes, flats or other suit-
able means whereby they may be rotated either together or separately as required.
In applying the invention to 'cone-adjusting' ball bearings, the washer is
introduced between the axle and a sleeve of comparatively large internal diameter.
on the back of the adjusting cone, the axle and the interior of the sleeve being
suitably screw threaded for the purpose.
The invention may be applied to either or both ends of the bearing.
From the above description the application of our invention to other suitable
bearings will be readily understood, modifications being made to suit special
circumstances as may be required.

page_text: Improvements in or relating to Bearings.
We, GEORGE SANDERS, Works Manager, and PICKERING PHIPPS, Chairman of
The Bamboo Cycle Co. Ltd., Petit Street, Wolverhampton in the County of Stafford,
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 relates to bearings and is especially applicable to adjustable ball
bearings such as are commonly fitted to velocipedes and the like. Our invention
has for its object improved means for locking the adjustment of such bearings;
and it consists essentially in an internally and externally screw-threaded washer
which is adapted to engage with both the adjusting part (cup or cone) of the
bearing and the part (case or axle) of the bearing into or onto which the said
adjusting part screws for adjusting purposes, the external and internal screw-
threads on the said washer being of different pitches.
In order that our invention may be properly understood and readily carried
into effect we have hereunto appended an explanatory sheet of drawings in the
several figures of which corresponding parts are marked with the same reference
numerals.
Figure I shows a longitudinal section through a velocipede hub constructed en
the "cup-adjusting" system and provided with a locking washer device according
to our invention.
Figure II is a similar view of a velocipede hub constructed on the "cone
adjusting" system and provided with a locking washer device according to our
invention.
In carrying out our invention as applied to the "cup-adjusting" ball bearing
hub of a velocipede (Figure 1) we adapt the adjusting cup 2 to screw further into
the case G than usual. On the back of the cup is formed a projecting concentric
sleeve 5 of comparatively small external diameter; and on the exterior of this
sleeve is formed a screw-thread of different, and preferably slower, pitch than that
in the case 6, and of either the opposite or, preferably the same, direction. A
washer having suitable external and internal screw-threads is adapted to be
screwed both onto the sleeve 5 of the cup and into the part of the case 6 which
projects over it. The washer is screwed a suitable distance onto the sleeve before
screwing the cup into the case and both are rotated together until the bearing is
adjusted to the right degree; then the washer alone is turned a little backward or
further forward until it jams and so locks the cup 2 and case 6 and hence the
adjustment of the bearing. The cup 2 and washer 7 are provided with pin
holes 10, flats 9 or other suitable means whereby they may be rotated either
together or separately as required.
In applying the invention to a "cone-adjusting" ball bearing velocipede hub
as shown in Figure II, the internally and externally screw-threaded washer 7 is
introduced between the screw-threaded part of the axle 6 and an internally screw-
threaded sleeve 5 of comparatively large internal diameter formed on the back of
the adjusting cone 2. The screw-thread in the sleeve 5 is formed of different, and
preferably slower, pitch than that on the axle 6, and of either the opposite or
preferably the same direction. The washer is screwed a suitable distance into the "
sleeve before serewing the cone onto the axle and both are rotated together until
the bearing is adjusted to the right degree; then the washer alone is turned a little
backward or further forward until it jams and so locks the cone 2 and axle 6 and
hence the adjustment of the bearing. The cone 2 and washer 7 are provided with
suitable means whereby they may be rotated, as before.

page_text: The invention may be applied to either or both ends of the bearing, but as a
rule it will be found convenient to fix one (12) of the two cups or cones by some
simpler means, as by screwing it tight up to a shoulder 11 and soft soldering it,
leaving the adjustment to be effected by the remaining cup or cone 2.
From the above description the application of our invention to other suitable
bearings will be readily understood, modifications being made to suit special
circumstances as may be required.
Having now particularly described and, ascertained the nature of our said
invention and in what manner the same is to be performed" we declare that what
we claim is
1. In means for locking the adjustment of bearings the employment of an inter-
nally and externally screw-threaded washer, the screw-threaded surfaces whereof
are adapted to engage with and lock together the adjusting piece of the bearing
and the part (case or axle) of the said bearing into or onto which the said adjusting
piece screws the internal screw-thread of the said washer being different in pitch
and either similar or opposite in direction, to the external screw-thread thereof,
substantially as set forth.
2. In a bearing having a screw-thread formed in the case and an adjusting piece
having two parts of different external diameters, which two parts are formed with
screw-threads differing from each other in pitch and either similar or opposite in
direction and the larger of which such screw-threaded parts is adapted to engage
with the screw-threaded part of the case,-means for locking the adjustment con-
sisting of an internally or externally screw-threaded washer adapted to engage
with both the screw-threaded part of the case and the smaller screw-threaded part
of the adjusting piece, whereby such washer is adapted to bind the adjusting piece
to the case, substantially as set forth.
3. In a bearing having a screw-thread formed on the axle and an adjusting
piece having two parts of different internal diameters, which two parts are formed
with screw-threads differing from each other in pitch and either similar or opposite
in direction, the smaller of which screw-threaded parts is adapted to engage with
the screw-threaded part of the axle, means for locking the adjustment consisting
of an internally and externally screw-threaded washer adapted to engage with both
the screw-threaded part of the axle and the larger screw-threaded part of the
adjusting piece, whereby such washer is adapted to bind the adjusting piece to the
axle, substantially as set forth.
4. In means for locking the adjustment of "cup-adjusting" bearings the com-
bination of: Firstly, an adjusting cup made externally of two diameters, both
parts being screw-threaded but with threads of different pitches and either similar
or opposite in direction; secondly, a case having a part suitably screw-threaded
internally to receive both the larger part of the said adjusting cup and the locking
washer next hereinafter referred to; and thirdly, an internally and externally
screw-threaded washer adapted to screw on to the smaller part of the adjusting cup
and to screw into the internally screw-threaded part of the case with the adjusting
cup, the said washer being further adapted to lock the adjusting cup to the case
on being independently rotated in either direction after adjustment of the bearing,
substantially as set forth.
5. In means for locking the adjustment of "cone-adjusting" bearings the
combination of:-Firstly, an adjusting cone made internally of two diameters both
parts being screw-threaded but with threads of different pitches and either similar
or opposite in direction; secondly, an axle having a part suitably screw-threaded
to receive both the smaller part of the adjusting cone and the locking washer next
hereinafter referred to; and thirdly, an internally and externally screw-threaded
washer adapted to screw into the larger part of the adjusting cone and to screw
onto the screw-threaded part of the axle with the adjusting cone, the said washer
being further adapted to lock the adjusting cone to the axle on being independently

page_text: rotated in either direction after the adjustment of the bearing, substantially as
set forth.
6. The improved means for locking the adjustment of bearings, constructed,
arranged and adapted to operate substantially as herein described with reference
to Figure I of the accompanying drawings.
7. The improved means for locking the adjustment of bearings, constructed,
arranged and adapted to operate substantially as herein described with reference
to Figure II of the accompanying drawings.
