Improvements in or relating to Bearings for Velocipedes and other
Vehicles.
CHARLES BINKS, 19, Burton Lane, York, Engineer, do hereby declare the
nature of this invention to be as follows:-
To lock the discs or cups of ball bearings I counterbore the end of the hub, bracket
or other bearing a suitable distance, and at the bottom of the counterbore so made,
I cut or mill a series of small teeth; I then take a disc or cup and cut one or
moro notches or grooves in it. I then screw the disc into its proper position. I
then make a washer which just file over the disc and into the counterbore, I cut
this through, at one end where it is cut through I put a tooth which just fits into
the groove cut in the disc and prevents it turning on the disc. The other end
I slightly thicken and on the thickened part I cut fine teeth to correspond with
the teeth cut on the counterbore. I then slightly bend the end away where the
teeth are cut so that the teeth do not stand level with the plane of the washer but
slightly lower than it. I then slip the washer over the disc in its required position,
I now take an ordinary locknut and screw it on the disc: as soon as it touches the
washer it presses against the thickened end and as it is screwed down it causes
the teeth in the end to engage in the teeth in the counterbore and so locks the disc.
On releasing the nut the teeth disengage themselves automatically owing to the
spring on the washer. Or I may omit cutting the teeth at the bottom of the
counterbore and as I prefer to harden and temper the teeth in the toothed washer,
the pressure of the nut would cause the teeth to embed into the plain bottom of
the counterbore and so prevent the disc turning.

Improvements in or relating to Bearings for Velocipedes and other
Vehicles.
I, CHARLES BENKS, of 19, Burton Lane, York, Engineer, 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:-
This invention relates to devices for locking the hearings of cycles and other
vehicles and consists essentially in a device which, while remaining engaged with
one part of the bearing, is adapted to be forced into engagement with the other
TDi 1

page_text: part of such bearing when the said parts are to be locked together, and which
device is also adaped to automatically disengage from the suid other part of the
bearing when such force is withdrawn, thereby unlocking the said parts and
consequently unlocking the bearing.
And in order that my invention may be properly understood I will further
describe the same with the aid of the accompanying drawings which show the
application thereof to a ball bearing velocipede hub.
Figure I is an elevation partly in vertical longitudinal section of such ball
bearing hub.
Figure II is a plan of one end of the said hub showing pårt broken away and the
washer and lock nut partly withdrawn.
Figures III, IV and are end elevations of the disc, washer and hub re-
spectively.
Like numerals refer to like parts in all the views.
In carrying out my invention as illustrated I counterbore the end of the case
2 of the hub a suitable distance and at the bottom of the counterbore 3 so made
I cut, mill or otherwise form a series of small radial or other suitable teeth 4.
In the exterior of the disc or cup 5 I form a longitudinal groove or notch 6. I
take a washer 8 the inner and outer diameters of which are such as to allow the
washer to slide over the cup 5 and into the counterbore 3. I cut this washer
through at one point, and at or near one of the ends so made I form an internal
tooth 7 adapted to engage in the groove 6 in the cup 5. The other end 9 of the
washer is made somewhat thicker than the remainder thereof and on one surface
of this thickened part are cut fine teeth 10 to correspond with the teeth 4 cut on
the bottour of the ecunterbore. The end 9 of the washer is bent slightly back
80 that the teeth 10 normally lie slightly below the general plane of their side
of the washer, and the other surface of the thickened end 9 normally stands
proud of the general plane of its side of the washer, as shown in Figures TI
and IV.
When the bearing has been adjusted by screwing the cup 5 the requisite distance
into the case 2, the washer 8 is slipped over the cup with its tooth 7 engaging
in the groove 6.
Next an ordinary lock nut or ring 11 is screwed on to the back of the cup 5.
The nut comes in contact with the thickened and bent end 9 of the washer first;
and then after the washer beds against the bottom of the counterbore,, further
screwing on of the nut presses down the thick end 9 of the washer and forces the
teeth 10 thereon into cugagement with the teeth 4 in the counterbore. As the
washer cannot rotate relatively to the cup by reason of the tooth 7 engaging in
the groove 6, and as the washer cannot rotate relatively to the case by reason
of the teeth 10 engaging in the teeth 4, it follows that the cup 5 is now incapable
of rotating relatively to the case 2 and the bearing is locked.
On releasing the lock nut 11 the end 9 of the washer 8 simultaneously springs
back into its bent position and thereby automatically withdraws its teeth 10 from
the teeth 4 in the bottom of the counterbore. This leaves the washer free to rotate
relatively to the case and consequently leaves the cup 5 free to be rotated for
adjusting or other purposes. It will be observed that it is not necessary to detach
any part in order to adjust the bearing as upon the teeth 10 disengaging from the
teeth 4 the cup 5 is set free to rotate, carrying the washer 8 with it. After the
bearing has been readjusted the nut II is retightened and the teeth 10 are caused
to re-engage with (probably another set of) the teeth 4.
Although I prefer to counterbore the end of the hub as above described in
order to obtain the cover afforded by the flange 12 formed thereby, such cover may
be obtained by counterboring the nut 11 instead of the end of the hub. Or the
counterboring may be omitted altogether if the washer 8 be made strong enough
to prevent springing, but I prefer to employ the cover. Again the teeta 4 may
he omitted. if desired, if the end of the case 2 he left soft, as the pressure of the
nut 11 will cause the teeth 10 (which are preferably hardened and tempered) to

page_text: bite into the plain bottom of the counterbore and so prevent relative rotation.
Similarly the teeth 10 might be omitted from the washer and the teeth 4 in the
case be hardened, but I do not prefer this construction. There may be more than
one groove 6 in the cup 5, and more than one tooth 7 on the washer 8, but there
must not be more teeth 7 than grooves 6, and the teeth 7 and grooves 6 must cor-
respond. The cup 5 and lock-nut 11 should be provided with the well-known
tommy holes, flats or the like to facilitate their rotation for adjusting purposes.
My invention may be applied to bottom brackets and other suitable bearings
in a similar manner; but I do not confine myself strictly to the above description
and the accompanying drawings as modifications may be made without, exceed-
ing the fair scope of my invention.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The improvements in the locking devices of the bearings of cycles and other
vehicles, substantially as herein described.
2. In a locking device for the bearings of cycles or other vehicles, a device
which is adapted, while remaining engaged with one part of the bearing, to be
forced into engagement with the other purb of such bearing when the said parts
are to be locked together, and also adapted to automatically disengage from the
said other part of the bearing when such force is withdrawn, thereby unlocking
the said parts.
3. In a locking device for the bearings of cycles or other vehicles, a washer cut
through at one point and having a tooth at or near one end adapted to engage in a
longitudinal groove cut in the exterior of the bearing cup, and having teeth on
one face of the other end adapted to engage with tho case of the bearing when
forced into engagement therewith, such end being bent back so that the teeth
thereon normally stand clear of the case and automatically disengage themselves
from the said case when the said force is released, substantially as ert forth.
