Improvements in or relating to Bearings.
I, ALBERT FARNELL, of 62 Manningham Lane, Bradford, Yorkshire, Cycle Factor,
do hereby declare the nature of this invention to be as follows:-
My invention relates to bearings and is especially applicable to adjustable ball
bearings, such as are commonly fitted to velocipedes and the like; and it consists
essentially in the hereinafter described improved means for locking the adjustment
of bearings.
In carrying out my invention as applied to the 'oup adjusting' hub or bottomi
bracket bearings of a velocipede the bearing cup is made externally of two diameters,
the larger part contains the ball race and the smaller part forms a aleove projecting
from the back of the cup around the central aperture therethrough. The larger part
ia screw threaded externally; the sinaller part is left plain. The end of the case is
suitably screw threaded internally and the cup is adapted to be screwed so far there-
into that the larger part is buried and the end of the sleeve stands approximately
flush with the end of the case. The end of the case is also provided with one or
more longitudinal grooves or recesses formed in the internally screw threaded part
thereof. A washer of suitable dimensions and having one or nore projections
adapted to enter the said grooves or recesses is passed on to the sleeve of the cup
and lies against the back of the larger part of the said cup. Behind the washer a
ring lock nut is screwed into the end of the case. The internal diameter of the
nut is sufficiently large to allow the nut to clear the sleeve part of the cup and the
external diameter is equal to that of the larger part of the cup and it is similarly
externally screw threaded. Upon the nut being screwed home, the washer is prsesed
tight against the cup and the cup is locked tight in the case. The projections ou
the washer engaging with the grooves or recesses in the case, prevent the washer
ro'ating independently of the case. hence the rotation of the lock nut in locking.
the adjustment prevented from being communicated to the cup.
To facilitate the rotation of the cup when required, the end of the sleeve may be
provided with horizontal holes adapted to receive the pegs of a peg spanner, or the
Said end may be adapted to project somewhat beyond the end of the case, the
projecting part being provided with flats or the like; similarly the ring may be
provided with horizontal holes, a hexagonal sleeve or the like whereby it may be
rotated.
The invention may be applied to either or both ends of the bearing, but as a rule
it will be found convenient to fix oue of the two caps or cones in some simpler
manner, as by screwing it tight up to a shoulder, and leave the adjustment to be
effected by the remaining cup or cone.
From the above description the application of my invention to other suitable

page_text: bearings will be readily understood, modifications being made to suit special
circumstances as may be required.

I, ALBERT FARNELL of 62 Manningham Lane, Bradford, Yorkshire, Cycle Factor,
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 bearings and is especially applicable to adjustable ball
bearings such as are commonly fitted to velocipedes and the like; and it consists
essentially in the hereinafter described improved means for locking the adjustment
of bearings.
And in order that the said invention may be properly understood and readily
carried into effect I will describe the same with the aid of the accompanying
drawings.
Figure I shows a longitudinal section through the "cup-adjusting" hub of a
velocipede.
Figure II shows a transverse section of the hub case on the line a-a in Fig I.
Figure III shows a certain washer in front and side elevation separate from the
hub and
Figure IV shows similar views of a certain locking ring separate from the hub.
Corresponding parts are marked with the same reference numerals in all the
figures.
In carrying out my invention as applied to the "cup-adjusting" hub bearing of
a velocipede, the bearing cup 2 is inade externally of two diameters, the larger
part 3 contains the ball race and the smaller part forms a sleeve 5 projecting from
the back of the cup around the central aperture therethrough. The larger part is
screw-threaded externally; the smaller part is left plain. The end of the case 6 is
suitably screw-threaded internally and the cup 2 is adapted to be screwed so far a
thereinto that the larger part 3 is buried and the end of the sleevo 5 stands
approximately flush with the end of the case 6. The end of the case is also pro-
vided with one or more longitudinal grooves or recesses 16 formed in the internally
screw-threaded part thereof. A washer 4 of suitable dimensions and having one or
more projections 14 adapted to enter the said grooves or recesses 16 is passed on to
the sleeve 5 of the cup and lies against the back of the larger part 3 of the said cup.
Behind the washer a ring lock nut 7 is screwed into the end of the case. The
internal diameter of the nut 7 is sufficiently large to allow the nut to clear the sleeve
part 5 of the cup, and the external diameter thereof is equal to that of the
larger part 3 of the cup and it is similarly externally screw-threaded. When the
bearing has been adjusted by rotating the cup 2 in the case 6, the washer 4 is
pressed against the back of the larger part 3 of the cup by the ring 7 being screwed
tight into the case 6; the screw-threads of the cup 2 are thereby forced so hard
against the screw threads of the case 6 that the said cup cannot rotate relatively
to the said case and the adjustment of the bearing is consequently locked. The

page_text: projections 14 on the washer 4 engaging with the grooves or recesses 16 in the
case 6 prevent the washer rotating independently of the case, hence the rotation
of the nut 7 in locking the adjustment is prevented from being communicated to
the cup 2.
To facilitate the rotation of the cup when required, the end of the sleeve ŏ may
be provided with horizontal holes adapted to receive the pegs of a peg spanner, or the
Baid end may be adapted to project somewhat beyond the end of the case as shown, the
projecting part being provided with flats 9 or the like; similarly the nut 7 may be
provided with horizontal holes 10, a hexagonal sleeve or the like, whereby it may be
rotated.
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 in some simpler manner,
as by screwing it tight up to a shoulder 11 and to leave the adjustment to be effected
by the remaining cup.
From the above description the application of my invention to other suitable
bearings will be readily understood modifications being made to anit special
circumstances as may be required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what mauuer the said is to be performed I declare that what I
claim is,
1. In a bearing adapted to be adjusted by rotating an adjusting piece which
screws into the case of the bearing, means for locking the adjustinent consisting of a
washer having projections on its exterior adapted to engage with longitudinal
grooves or recesses in the case so as to prevent such washer rotating relatively to the
case, and an externally screw-threaded ring adapted to scrow into the end of the case
and press the washer against the adjusting piece whereby the adjusting pieco is
prevented from rotating relatively to the case, substantially as set forth.
2. In means for locking the adjustment of bearings adapted to be adjusted by
rotating an adjusting piece which screws into the case of the bearing, the combination
of: firstly, an adjusting piece having an external screw-thread; secondly, a case
having a part internally screw-threaded to receive the adjusting piece and also one
or more longitudinal grooves adapted to receive the washer next hereinafter referred
to; thirdly, a washer adapted to pass into the end of the case behind the adjusting
piece and having one or more projections adapted to enter the groove or grooves in
the case and prevent rotation of the said washer; and fourthly, an externally screw-
threaded ring adapted to screw into the case behind the washer and, by pressing the
washor aguinst the adjusting piece, lock the said adjusting piece to the case,
substantially as set forth.
3. The improved means for locking the adjustment of bearings substantially as
herein described with reference to the accompanying drawings.
