page_text: I, Miss ALICE DENTON, of Newbold, neat Chester, in the County of Chester, do
hereby declare the nature of thus invention to be as follows.
Hitherto the use of tucycles has been greatly restricted owing to then weight
and the space that they occupy during transit and in storage.
My invention is designed to provide a machine which will embody the advan-
tages of tucycles while avoiding the defects thereof, by reducing then excessive
weight, bulk, and general clumsiness
In carving my invention into effect, I form the back wheel of the machine with
duplex tyres and rim, that is to say I form two tries side by side at a suitable
distance apart on the one wheel, so as to form a tread that will keep the machine
upught even when at rest In other respects the machine is similar to an ordinary
safety bicycle, the advantage of my invention being that the weight is little in
excess of an ordinary safety bicycle, and yet the machine is kept upright and
much less space is taken up in storage A ve important point also 18 that a
machine constructed on these lines will pass through a very mailow door way
Instead however of forming the wheel with uplex tyres, I form my cycle with
two separate back wheels placed near together side by side These wheels may be
fastened together so as to form one wheel as it were, or they may be made to
revolve independently

I, Miss ALICE DENTON, of Newbold, near Chester, in the County of Chester, lo
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:-
Hitherto the use of tricycles has been greatly restricted owing to their weight
and the space that they occupy during transit and in storage
My invention is designed to provide a machine which will embody the advan-
tages of tricycles while avoiding the defects thereof, by reducing their excessive
weight, bulk, and general clumsiness

page_text: The invention will be understood from the following desciption, reference being
had to the accompanying diawings, in which,
Figure 1 is a fiunt elevation of a cycle with my invention applied thereto;
Figure 2, a plan,
Figure 5, a plan of a slight modification
Retening to Figures 1 and 2, 1 form the back-wheel of the machine with duplex
tyies and aim, that is to say I form two tyres A A side by side, at a suitable
distance apart on the one wheel, so as to form a tread that will keep the machine
upright even when at rest In other respects the machine is similar to an ordinary
safety bicycle, the advantage of my invention being that the weight is little in
excess of an ordinary safety bicycle and yet the machine is kept upright and
much less space is taken up in storage A very important point also is that a
machine constructed on these lines will pass through a very narrow doorway
Instead of forming the wheel with duplex tyies, I form my cycle with two
beparate backwheels B B placed near together side by side These wheels may be
fastened together so as to form one wheel as it were, or they may be made to
revolve independently. In the former case both wheels are driven by the diving
cranks, and there is no necessity to provide an arrangement for enabling them
to revolve independently, as then short distance apait enables the machine to
readily pass round curves without providing special provision for enabling one
wheel to revolve quicker than the other in tuning Each wheel 18 aanged
within the width of the handles or treadles on either of them, and therefore a
machine constructed on these lines will occupy no more 100m in a railway train
or in a stall or elsewhere than an ordinary bicycle does, and will also pass through
a doorway of ordinary width
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 18:-
1 The improvement in bicycles which consists in forming the backwheel thereof
with a pair of tyres located side by side at a suitable distance apart on the one
wheel, so as to form a tread that will keep the machine upright even when ot
1est, substantially as described
2 A tricycle having two separate backwheels but placed near together side by
side within the width of the handles or treadles or either of them, whereby a
tricycle so constructed will occupy no more (or but little more) 100m in a railway
tain or in a stall or elsewhere than an ordinary bicycle does, substantially as
described.
