PROVISIONAL SPECIFICATION.
Improvements in or connected with Hubs or Naves for Cycle and
other Wheels.
A communication from abroad by RAOUL BENTZ, Merchant, and EDMOND DE
SIBLAS, Mechanic, both of Paris, in the Republic of France.
I, JAMES GRIEVE LORRAIN, M.I.E.E., M.J. Mech. E., of Norfolk House,
Norfolk Street, Strand, London, in the County of Middlesex, Chartered Patent
Agent, do hereby declare the nature of this invention, as communicated to me
by my foreign correspondents, to be as follows:-
This invention relates to hubs or naves for cycle and other wheels by means of
which certain advantages are obtained.
The object of our invention is to have a hub which will enable its parts or the
wheel to be easily removed. A detachable spindle traverses the hub longitudinally,
the shaft or axle, properly so called, being constituted by a tube carrying the fixed
and revolving cones. This tube is threaded at each end for the reception of the
fixed cones.
The revolving cones are united by a tube enveloping the tubular
shaft. The parts are attached by means of the detachable spindle which lies
within the tubular shaft, and which is threaded at both extremities so that by
means of nuts the whole can be bound together. The tubular shaft is shorter than
the distance between the external ends of the fixed cones, so that in tightening up
the nuts on the detachable spindle pressure will be upon the cones and not on the
tubular shaft.
To detach a wheel all that has to be done is to unscrew one of the nuts when the
detachable spindle can be drawn out and the wheel removed.

I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I. Mech. E., of Norfolk House,
Norfolk Street, Strand, London, in the County of Middlesex, Chartered
Patent Agent, do hereby declare the nature of this invention (as communicated
to me by my foreign correspondents) 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 hubs or naves for cycle and other wheels by means of
which certain advantages are obtained.
The object of our invention is to have a hub which will enable its parts or the
wheel to be easily removed.

page_text: in the accompanying drawings,
Fig. 1. is a longitudinal section of the hub of a rear wheel of a cycle.
Fig. 2 is a side elevation of one of the ball cases.
Fig. 3 is an elevation of the detachable spindle removed from the hub.
Fig. 4 is a longitudinal section of the tube forming the shaft or axle, properly
50 called.
Fig. 5 is a longitudinal section of the hub of a front wheel of a cycle.
Similar letters of reference indicate similar parts.
A detachable spindle E traverses the hub longitudinally, the shaft or axle,
properly so called, being constituted by a tube A carrying the fixed and revolving
cones. This tube is threaded at each end for the reception of the fixed cones B.
The revolving-cones C, one of which carries the sprocket wheel K, are united by
a tube D surrounding the tubular shaft A. The parts are united to the fork by
means of the detachable spindle E, which lies within the tubular shaft A, and
which is threaded at both extremities so that by means of nuts screwed on the ends
projecting through the eyes of the fork the whole can be bound together. The
tubular shaft is shorter than the distance between the external ends of the fixed
cones, so that in tightening up the nuts on the detachable spindle pressure will be
upon the cones and not on the tubular shaft.
To detach a wheel all that has to be done is to unscrew one of the nuts when
the detachable spindle can be drawn out and the wheel removed.
We desire it to be understood that we do not limit ourselves to the precise
forms of the parts indicated as these may be varied within considerable limits.
Having now particularly described and ascertained the nature of my said inven-
tion, as communicated to me by my foreign correspondents, and in what manner the
same is to be performed, I declare that what I claim is :-
The arrangement and combination of parts substantially as set forth.
