EBENEZER WILLIAM HUGHES 72A Clayton Road Peckham S.F. Civil Engineer
I do hereby declare the nature of this invention to be as follows:-
This invention is for the purpose of reducing friction in chain working, adapted for
Bicycles and the like, and which I describe as follows. The chain consists of double
links throughout and all the same length, having small wheels placed at their
connections and between the double links, and held by rivets passing through the
Sinall wheels (and links) heads, so that the small wheels can revolve should any
resistance occur. The chains pass round the semi-circumference of the chain wheels
or holders and continued from wheel to wheel forming a band. The wheels, or chain
holders I form with a rim, preferably half an inch in width, all round, and from the
centre of this rim I make projections at right angles outwardly.
These are hollowed out to receive one half of the small wheels which are in contact
with the rim and the distance between them, corresponding with the chain links all
round the circumference of the chain wheels or holders. The remainder of these
projections outside to be rounded off with reverse curves so as to enable these
projections (between the double links) to enter and leave freely. These projections to
alternately vary in thickness to suit the spaces between the double links before
described.
EBENEZER WILLIAM HUGHES 72A Clayton Road Peckham, Surrey S.E. Civil
Engineer I 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 is for the purpose of reducing friction in chain working, adapted for
Bicycles and the like, and which I describe as follows. The chain consists of double
links throughout, and all the same length having small wheels placed between them,
and at their connections, and held by rivets passing through the small wheels and
link heads, so that the small wheels can revolve freely should any resistance occur.
The chains pass round the semi-circumference of the chain wheels or holders and
continued from wheel to wheel forming a band. (The wheels or chain holders I form
with a rim preferably half an inch in width all round) and from the centre of this rim I
make projections at right angles outwardly. These are hollowed out to receive one half
of the small wheels which are in contact with the rim, and the distance between them

holders. The remainder of these projections outside to be rounded off with reverse
curves, so as to enable these projections (between the double links) to enter and leave
freely. These projections to alternately vary in thickness to suit the spaces between
the double links W and N before described and shewn on drawing.
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 :-
Firstly the sinking of half the small wheels in corresponding recesses round the
projection as described and
Secondly rounding off these projections so as to facilitate the small wheels freely
entering and leaving the recesses before referred to.
