page_text: Date of Application, 23rd Feb., 1898
Complete Specification Left, 29th Oct., 1898-Accepted, 3rd Dec., 1898
I, HERBERT MORTON HEPWORTH, of Headingley House, Leeds, in the County
of York, Clothier, do hereby declare the nature of this invention to be as
follows:
The object of my invention is to efficiently lock the adjusting discs of cycle
bearings.
On the barrel of the hub I cut out a short portion, and upon a portion of the
periphery of the disc I form small teeth or serrations. I then place in the recess
cut out of the barrel of the hub a small locking piece with teeth or serrations
on its underside and corresponding in shape and size to the portion cut away
from the barrel.
The nut is screwed up over the locking piece and holds it in position.
A mark is placed upon the barrel to show the position of the locking piece.
It is equally applicable to the bearings of hubs and crank brackets.

pants in Cycle Bearings.
I, HERBERT MORTON HEPWORTII, of Headingley House, Leeds, in the County
of York, Clothier, 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:-
The object of my invention is to efficiently lock the adjusting discs or cones
of cycle or the like bearings.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation of one end of a cycle hub with my improvements
applied.
Fig. 2 is an end elevation, and Fig. 3 a plan, of Fig. 1, each having the nut
and locking piece removed. Fig. 4 is an elevation of disc or cone detached.
In carrying out my invention I cut out at A a short portion of the barrel B

of the hub or crank bracket. In the recess so formed I place a small locking
piece C, corresponding in size and shape to the portion cut away from the barrel,
and having a number of teeth or projectious D on its underside. The said teeth
or projections D engage with teeth or serrations E formed upon a portion of the
periphery of the disc or cone F, thus locking the said disc or cone F within the
barrel B. The locking piece C is retained in position by means of a nut or
screwed cap G screwing on the end of the barrel.
When the bearing requires to be adjusted the cap G is unscrewed and the
locking piece C removed; the disc or cone F can then be tightened or slackened
as required and again locked by replacing the locking piece C and cap G.
A suitable mark may be provided on the barrel to indicate the position of the
locking piece C.
Although shown in the accompanying drawing as applied to a hub, the locking
device is equally applicable to the bearings of crank brackets.
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. In a disc-adjusting bearing for cycles or the like vehicles, the employment
of a removable locking piece held in position within a recess in the barrel by
means of a cap, and having teeth or projections which engage with teeth or
serrations on the periphery of the disc or cone, substantially as shown and
described.
2. In a disc-adjusting bearing for cycles or the like vehicles, the combination
of the barrel B having a recess A, the removable locking piece C having teeth
or projections D, the adjusting disc or cone F having circumferential teeth or
serrations E, and the nut or screwed cap G, all arranged substantially as, and for
the purposes, shown and described.
