PROVISIONAL SPECIFICATION.
Improvements in or relating to Hubs for Cycles and other Vehicles.
I, FERNAND JOSEPH WALLAERT of 21, Grove Terrace, Highgate Road,
London, N.W., Cycle Agent, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the caps which are screwed over the cones at each end of
the axle to retain in position the balls of the bearing and the object is to render the
caps adjustable. In carrying out my invention I proceed in or in about the following
manner, that is to say, I provide around the edge of the rim of each cap which is
nearest the hub when the cap is screwed in, a number of notches, and through the
flanges of the hub I pass a small screw, pin, spring catch or other contrivance, so
that when the cap is fully screwed in, the screw, pin or the equivalent will enter one
of the notches in the rim and so retain the cap.

Improvements in or relating to Hubs for Cycles and other Vehicles.
I, FERNAND JOSEPH WALLAERT of 21 Grove Terrace, Highgate Road
London N. W. Cycle Agent, do hereby declare the nature of my said 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 effect improvements in the method of securing ball
bearing cups or discs in the hubs of cycles and other road vehicles, whereby the
same may be locked after adjustment without altering the parallelism of the bearing
surfaces.
According to my invention I form the cup or disc, which is screw threaded
externally, with slots or grooves extending from the internal edge of the cup or disc
to a convenient distance towards the outer edge thereof.
That portion of the hub which contains the bearings generally exterior to the
flanges, is provided with a screw, pin, spring catch, or other contrivance arranged to
engage with the slots or grooves in the cup or disc.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation partly in section of cycle driving wheel hub fitted according.
to my invention.
Fig. 2 is a section of Fig. 1 on the line X-X.
Fig. 3 is an elevation of a bearing cup or disc, constructed according to my

page_text: Fig. 4. is a sectional end view of a hub illustrating one modification of my
invention.
As generally constructed, a disc adjusting hub consists of the barrel a, flanges b
and bearings or shells c, provided with an axle d, fixed cones e and discs or cups f
and balls 9, one of the discs or cups being fixed in position, and the other left
adjustable after the complete bearing has been fitted in the hub.
I form the discs or cups f with slots h, Figs. 1, 2 and 3, or grooves h', Fig. 4, in
which slots or grooves a screw, pin, spring catch, or other device may engage
whereby the disc or cup becomes locked in the hub. In Figs. 1 and 2 a screw i is
shown passing through the bearing or shell c which is referred to in my Provisional
Specification as a flange. The side walls of the slots may be cut slightly conical, or
the lower end of the screw or pin may be coned, to ensure a rigid fixing.
In Fig. 4, the pin k is provided with a spring steel band to clip round the bearing
or shell whereby the pin is held in position. In some cases the pin may be attached
to one end of a flat spring the other end of which is secured to the bearing or
shell.
When it is desired to adjust the cup or disc f, the screw i is partly withdrawn so
as to clear the screw thread of the disc or cup f when the cup is free to be rotated to
effect the proper adjustment. The screw i is then driven home into the slot which
happens to be beneath the screw. In like manner the modification shown in Fig. 4
is operated, the pin being withdrawn during the rotation of the disc or cup and again
replaced when the proper adjustment is accomplished.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein before described improvements in or relating to hubs for cycles and
other vehicles, substantially as set forth.
2. In hubs for cycles and other vehicles, the application and use of a screw, pin,
spring catch, or other device in combination with slots, grooves, or flats formed in or
on the internal portion or edge of the disc or cup, for the purpose of preventing
accidental rotation of the said discs or cups within the bearing after adjustment,
substantially as hereinbefore described and illustrated by the drawings.
3. The particular construction and arrangement of bearings for the hubs of cycles
and other vehicles, substantially as hereinbefore described and shown on the
accompanying drawings.
