PROVISIONAL SPECIFICATION.
Improvements in or relating to Safety Bicycles.
I, WALTER WHETSTONE of Bishop Street, Leicester, Solicitor, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to improvements in safety bicycles, and consists in
providing means to be employed in combination with the back wheel of a bicycle to
minimize or decrease the shock or jar to the rider when passing over an obstacle or
uneven road.
According to my invention there may be adapted in a suitable manner to one or
both sides or ends of the axle, or any other suitable connecting part of the back wheel
or adjacent framework, a spring or equivalent.
This spring may, if desirable, be enclosed within a tubular case, which may, or may
not, be an integral part of the framework of the machine, or the terminating ends of
the spring or springs may be in contact with one or more suitable plates, or equivalent
incans, or otherwise suitably arranged, constructed or adapted to receive the shock or
jar under the circumstance mentioned, and at the part of the machine before referred to.
Dated this 1st day of October 1889.

COMPLETE SPECIFICATION.
Improvements in or relating to Safety Bicycles.
I, WALTER WHETSTONE of Bishop Street, Leicester, Solicitor, 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 has reference to improvements in safety bicycles, and consists in
providing means, to be employed in combination with the back wheel thereof to
minimize or decrease the shock or jar to the rider when passing over an obstacle or
uneven road.
According to this invention there may be adapted in a suitable manner to one or
both sides or ends of the axle, or any other suitable connecting part of the back wheel
or adjacent framework, a spring or equivalent.
This spring may, if desirable, be enclosed within a tubular case, which may, or may
not, be an integral part of the framework of the machine, or the terminating ends of
the spring or springs may be in contact with one or more suitable plates, or equivalent
means, or otherwise suitably arranged, constructed, or adapted, to receive the shock or
jar under the circumstances mentioned, and at the part of the machine before
referred to.
The invention will be understood from the accompanying drawing representing so
much of the rear or driving wheel of a safety bicycle, as is necessary to illustrate this
invention.
A A are parts of the framework to the terminating ends of which may be
attached or formed integrally therewith a bracket B.
The bracket B has a vertical spindle C passing through it and is split at its outer
ends Bi to admit of being tightened on the spindle C.
At a convenient point in its length the spindle C is enlarged and bored to fit on or
receive the end of the axle D of the rear or driving wheel and round its lower part is
encircled by a spring the upper end of which is in contact with the under surface
of the bracket B and the lower end with a collar or washer C fitted on the end of the
spindle C and secured in position by the screw-bolt C³.

page_text: From this it will be readily understood that any shock or jar caused by the rear
wheel passing over an obstacle will be conveyed to the bracket B on the framework,
and the spring C¹ will be depressed thereby greatly reducing the vibration.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a safety bicycle the application to the rear or driving wheel of a spring for
minimizing the vibration substantially as described and illustrated in the accompanying
drawing.
2. In a safety bicycle the combination with the axle of the rear or driving wheel of
a bracket such as B spindle such as C and spring such as C¹ substantially as and for
the purpose described and illustrated in the accompanying drawing.
3. In a safety bicycle constructing the framing with a bracket such as B having
connected thereto a spring encircled spindle C. C for minimizing the vibration on the
rear or driving wheel substantially as described and illustrated in the accompanying
drawing.
