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 cycles, and relates more particularly
to bicycles of the type known as safety. My invention consists in making the
front wheel materially smaller than the rear or driving wheel. The front wheel
may, in accordance with my improvements, be one half, approximately, the size
of the rear or driving wheel and under this construction the bicycle is made lighter
and is more easily steered. With my said small front wheel I am enabled to
make the steering rod and the handles considerably lighter than heretofore. Hereto-
fore the triangular shaped frame between the wheels had the front tube of the
frame sloping upwards from the crank axle to a position near the handles, whereas
by the employment of the small front wheel, the said tube may be brought nearer
to a horizontal position that is to say the top of the said tube may be lowered in
accordance with the lowering of the height of the front wheel, thereby bringing
this part of the framing nearer to the axle of the front wheel, whereby greater
strength is obtained and by reason of the small size of the front wheel the steering
rod mey be materially reduced in weight. In order to make such a bicycle suitable
for ladies, I bring down the top horizontal tube of the frame so that its rear end is
at the saddle post, as before, but its front end is sloped downwards so that its
front end joins the front end to the lower tube of the framing riz. in proximity
with the top of the small front wheel.

tion the cycle is made lighter and is more easily steered. With my said smaller
front wheel I am enabled to make the steering rod and the handles lighter than

tube of the frame sloped upwards from the crank axle of the rear wheel to a
position near the handles, whereas by the employment of my smaller front wheel,
the said tube may be brought nearer to a horizontal position, that is to say the top
of the said tube may be lowered in accordance with the lowering of the height of
the front wheel, thereby bringing this part of the framing nearer to the axle of
the front wheel, whereby greater strength is obtained; and by reason of the
smaller size of the front wheel the steering tube and rod may be materially
reduced in weight and the prongs of the front fork reduced in length to suit the
reduced size of the wheel and are thus stronger than hitherto.
Figure 1 of the accompanying drawings ollustrates my improved bicycle having
the smaller front wheel A with the new arrangement and construction of the
lower tube B, steering tube and rod C, and fork D.
In ladies bicycles Fig. 2, the top horizontal tube is replaced by the tube E
extending from the joint F to or near to the joint G.
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 improved construction of bicycle having the small or smaller front
wheel A, constructed and arranged, substantially as and for the purposes herein-
before described and shewn in the accompanying drawings.
2. The improved construction of bicycle having the new arrangement and con-
struction of the lower tube B, steering tube C, and rod and fork 1) substantially
as and for the purposes hereinbefore described and shewn in the accompanying
drawings.
3. The improved construction of ladies bicycles having the new arrangement
and construction of the upper tube E, lower tube B, steering tube and rod C¹ and
fork, substantially as hereinbefore described and shown in the accompanying
drawings.
