Improvements in Detachable Hubs for Cycle Wheels.

I, HUGH THOMAS, of 51, Peel Street, off London Road, in the City of Glasgow,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the hubs of cycle wheels and has for its object to
better adapt such hubs for ready detachment from the forks or frame of the
cycle.
To that end the spindle on which the wheel hub is fitted to turn is bored or
made tubular and through it is passed a central solid spindle or mandrel which
may be very slightly tapered so that when driven home it firmly engages the
hollow spindle. The hollow spindle which may be screw-threaded throughout its
length is passed through the hub centre and on it are fitted the usual cones for
the ball bearings, the ball race being formed by the cups which are fitted in the
hub in the usual way. In lieu of being screw-threaded throughout, the hollow
spindle may have one cone fitted as a sliding sleeve upon it engaging a collar at
the end of the spindle whilst the other end of the spindle is screw-threaded and has
the other cone fitted thereon so as to provide for adjustment of the ball bearings.
When the cone is adjusted it is retained by means of a lock nut. When the
wheel is in position with the hub between the cycle forks the central solid spindle
is passed through it and the slots or eyes of the forks and is secured by a screw
nut at one end. The withdrawal of the solid spindle upon removal of the nut
permits of the drawing out of the wheel from between the forks; and readjustment
of the bearings is unnecessary when the wheel is replaced.

I, HUGH THOMAS, of 51, Peel Street, off London Road, in the City of Glasgow,
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 the hubs of cycle wheels and has for its object to
better adapt such hubs for ready detachment from the forks or frame of the
Levele

page_text: The invention is illustrated by the accompanying drawings, Figure 1 being a
longitudinal vertical section of the improved hub and Figure 2 an end view of the
same.
The spindle A on which the wheel hub B is fitted to turn is bored or made
tubular and through it is passed a central solid spindle or mandrel C which may be
very slightly tapered so that when driven home it firmly engages the hollow
spindle A. The hollow spindle A, which may be screw-threaded throughout its
length, is passed through the hub centre B and on it are fitted the usual
cones D, D', for the ball bearings, the ball race being formed by the cups B¹, B³,
which are fitted in the hub in the usual way. In lieu of being screw-threaded
throughout, the hollow spindle A may have one cone I) fitted as a sliding sleeve
upon it and having projections 12 engaging a slotted collar. A¹ at the end of the
hollow spindle A whilst the other end of the spindle is screw-threaded and has
the other cone D' fitted thereon so as to provide for adjustment of the ball bearings.
When the cone I₁ is adjusted it is retained by means of a lock nut E. When the
wheel is in position with the hub B between the cycle forks F the central solid
spindle is passed through it and the slots or eyes of the forks and is secured by
a screw nut at one end. The withdrawal of the solid spindle or mandrel C upon
removal of the cap nut C¹ permits of the drawing out of the wheel from between
the forks; and readjustment of the bearings is unnecessary when the wheel is
replaced.
The central spindle C may also for the sake of lightness be made hollow and
plugged at its ends as shewn.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
1 claim is
In a cycle hub adapted to permit of the detachment of the wheel from the
cycle forks or frame, the combination with a hub having the ordinary fixed ball
races, of a tubular spindle carrying cone bearings, one or both of which is removable
and adjustable, and a removable central spindle or mandrel within the bearing
spindle for attachment to the cycle forks, substantially as described.
