Improvements connected with Cycle and similar Wheels.
I, PIERRE AMBJORN, Comte de Sparre, of 42, Brockley Road, New Cross, in the
County of Kent, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in cycle and similar wheels.
Such wheels as is well known, usually consist of a metal or other rim tied to
a boss or nave by steel spokes, the said spokes being secured to the boss by means
of flanges formed thereon and having holes through which the ends of the spokes
are passed. Such spokes are frequently damaged or broken and, in the case of the
driving wheels of cycles, it is then necessary to remove the chain or sprocket wheels
before the spoke can be removed and replaced as the said chain wheels are of
larger diameter than the spoke flanges.
Now my invention has for its object to remedy this defect and to this end I
form the flange upon the end of the wheel nave adjacent to the sprocket wheel
of a diameter larger than that of the said sprocket wheel thereby enabling a
damaged or broken spoke to be removed and a new spoke to be put in position
without the necessity of removing the sprocket wheel.

Improvements connected with Cyele and similar Wheels.
1, PIERRE AMBJORN, Comte de Sparre, of 42, Brockley Road, New Cross, in the
County of Kent, Civil 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 improvements in cycle and similar wheels.
Such wheels, as is well known, usually consist of a metal or other rim tied to
a boss or nave by steel spokes, the said spokes being secured to the boss by means
of flanges formed thereon and having holes through which the ends of the spokes
are passed. Such spokes are frequently damaged or broken and, in the case of the
driving wheels of cycles, it is then necessary to remove the chain or sprocket wheels
before the broken spoke can be removed and replaced as the said chain wheels are of
larger diameter than the spoke flanges.

page_text: Now my invention has for its object to remedy this defect and to this end I
form the flange upon the end of the wheel nave adjacent to the sprocket wheel
of a diameter larger than that of the said sprocket wheel thereby enabling a
damaged or broken spoke to be removed and a new spoke to be put in position
without the necessity of removing the sprocket wheel.
My invention will be readily understood by reference to the accompanying
drawing, in which:-
Figure 1 is an elevation of a wheel hub provided with an enlarged flange; and
Figure 2 is an end view of Figure 1 looking in the direction of the arrow in
the said figure.
In these figures a is the wheel hub and b, c are the flanges thereon and d is
the sprocket wheel.
It will be readily understood that by making the flange c sufficiently large to
permit of the holes e, e therein, through which the spokes are threaded, being
arranged outside the teeth of the sprocket wheel the spokes can be readily threaded
through or removed from the wheel without necessitating the removal of the said
sprocket wheel.
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
I claim is:
1. The improvement connected with cycle and similar wheels consisting in
forming the flange upon that end of the wheel hub adjacent to the sprocket wheel
of a diameter larger than that of the said sprocket wheel, substantially as, and
for the purpose, described.
2. The manufacture and use of hubs for cycle and similar wheels substantially
as hereinbefore described and illustrated in the accompanying drawing.
