EBENEZER WILLIAM HUGHES 72 Clayton Road Peckham S.E., Civil Engineer,
I do hereby declare the nature of this invention to be as follows:-
The object of this Invention is to dispense with chains, and substitute a series
of wheels, in line and close contact with each other, and consisting of (preferably)
two wheels,' having teeth all round of the usual type, but between these two wheels
before mentioned I fix a third wheel between them of a special form which I
term a transferring wheel, but turning in an opposite direction when working,
so that the treadle wheel and driving wheel shall revolve in the same direction
forward, and the special wheel communicate the motion in the same direction,
by reversing its action.
The special wheel I construct with a hollow groove outwardly, round the rim
or periphery, inside which I place a series of short tubes, the lengths corresponding
with the width of the groove, and through these tubes and sides of rim I pass
axles and rivetted, so that these tubes can revolve freely round the axles referred
to.
The diameter of these Tubes so correspond with the size of the teeth in the
other wheels before described, so that the three wheels will work in unison, and
the friction reduced to the, minimum.
Should bevel wheels be used on this principle the tubes must be conical and
the other wheels cast to correspond.
COMPLETE SPECIFICATION.

EBENEZER WILLIAM HUGHES 72* Clayton Road, Peckham, Surrey, 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:-
The object of this Invention is to dispense with chains, and substitute a series
of wheels in line, and close contact with each other, and consisting of (preferably)
two wheels having teeth all round of the usual type, but between these two wheels
before mentioned I fix a third wheel B between them of a special form which I
term a transferring wheel, but turning in an opposite direction when working
so that the treadle wheel C and driving wheel D shall revolve in the same direction

page_text: forward, and the special wheel communicate the motion in the same direction
by reversing its action. The special wheel B I construct with. a hollow groove
outwardly round the rim or periphery inside which I place a series of short
tubes E the lengths corresponding with the width of the groove, and through
these tubes and sides of rim I pass axles F and rivetted, so that these tubes can 5
revolve freely round the axles referred to.
The diameter of these tubes E to correspond with the size of the teeth in the
other wheels C and D before described so that the three wheels will work in
unison and the friction reduced to the minimum.
Should bevel wheels be used on this principle the tubes must be conical, and 1
the other wheels cast to correspond.
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 :-
The special or transferring wheel 13 previously set forth distinctly and as before 1
described in combination with the other wheels C and D referred to.
