Improvements in Bicycles.
I, CHARLES DENTON ABEL of No. 28 Southampton Buildings in the County of
London, Consulting Engineer and Chartered Patent Agent, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the construction of a framework with spring action for
bicycles by which means the riding upon a machine having ordinary solid rubber
tyres, is rendered just as elastic and pleasant as ou a machine having pneumatic
tyres. The advantage of this is obvious, as the solid rubber tyre is not only
cheaper but also much stronger and more durable than the pneumatic tyre, and,
not requiring to be pumped, is always ready for use.
I will describe the invention with reference to the accompanying drawing in
which Fig. 1 shews a side elevation of the improved bicycle frame, and Figs. 2, 3
and 4 shew details to an enlarged scale.
The fork B of the rear wheel embraces the pedal shaft bearing G by means of
two split eyes e and e' that are secured by bolts f, as shewn in the plan at Fig. 3,
so that the fork can pivot on the bearing G. The forked strut A passing from
the fork B of the rear wheel to the saddle support C is connected at its upper end
to a plate D, which carries two arms a with bearings for a bolt or roller b which
can slide up and down in slots c formed on the bracket E fixed to the saddle
support C. On the head piece of the saddle support are fixed two backward
extending arms g between which and the above mentioned plate D are mounted
two sets of coiled springs F F³ and F' F2.
By means of this construction, in riding, all the concussions that are usually
transmitted from the rear wheel to the saddle are taken up by the coiled springs,
which are first compressed and afterwards resume their original position, so that
the effect on the rider will be just the same as though the wheels had pneumatic
tyres.

1, CHARLES DENTON ABEL, of No. 28 Southampton Buildings in the County
of London, Consulting Engineer and Chartered Patent Agent, 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 the construction of a framework with spring action for

cheaper but also much stronger and more durable than the pneumatic tyre, and,
not requiring to be pumped, is always ready for use.
I will describe the invention with reference to the drawings accompanying the
Provisional Specification, of which Fig. 1 shews a side elevation of the improved
bicycle frame, and Figs. 2, 3 and 4 shew details to an enlarged scale.
The fork B of the rear wheel embraces the pedal shaft bearing G by means of
two split eyes e and e' that are secured by bolts f, as shewn in the plan at Fig. 3,
so that the fork can pivot on the bearing G. The forked strut A, passing from
the fork B of the rear wheel to the saddle support C, is connected at its upper end
to a plate D, which carries two arms a with bearings for a bolt or roller b which
can slide up and down in slots c formed on the bracket E fixed to the saddle
support. C. On the head piece of the saddle support h are fixed two backward
extending arms 9 between which and the above mentioned plate D are mounted
two sets of coiled springs F F³ and F1 F2.
By means of this construction, in riding, all the concussions that are usually
transmitted from the rear wheel to the saddle are taken up by the coiled springs,
which are first compressed and afterwards resume their original position, so that
the effect on the rider will be just the same as though the wheels had pneumatic
tyres.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The construction of a bicycle frame with springs arranged and operating
substantially as described with reference to the drawings.
