Improvements in Velocipedes.
I, WILLIAM ARTHUR AIKIN, of 14 Sumner Place, Onslow Square, in the
County of Middlesex, Doctor of Medicine, do hereby declare the nature of this
invention to be as follows:-
According to this invention the saddle and the pedal axis with the pedals are
carried by a bar free to play up and down independently of the rest of the
machine.
For this purpose the upper and lower backbones are bifurcated or formed with
eyes for the bar to pass through and it is hung from them by springs.
Preferably the bar carries at the point where it passes through each backbone
two studs which are supported by springs passing over the frame on either side
with india rubber rings or pads interposed.
The pedal axis is connected to the axis of the driving wheel by radius rods so
that the driving chain is always kept tight.
In cases where the play of the bar is not sufficient the bearings of the pedal
axis instead of being fixed rigidly to it may be carried by arms jointed to its
lower end.
Dated this 28th day of May 1896.

COMPLETE SPECIFICATION.
Improvements in Velocipedes.
I, WILLIAM ARTHUR AIKIN, of 14 Sumner Place, Onslow Square, in the
County of Middlesex, Doctor of Medicine, 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:-
According to this invention the saddle and the pedal axis with the pedals are
carried by a bar free to play up and down independently of the rest of the
machine.
For this purpose the upper and lower backbones are bifurcated or formed with
eyes for the bar to pass through and it is hung from them by springs.
Preferably the bar carries at the point where it passes through each backbone
two studs which are supported by springs passing over the frame on either side with
indiarubber rings or pads interposed.
The pedal axis is connected to the axis of the driving wheel by radius rods so
that the driving chain is always kept tight.
In cases where the play of the bar is not sufficient the bearings of the pedal
axis instead of being fixed rigidly to it may be carried by arms jointed to its
lower end.
Figure 1 is a side elevation of a bicycle constructed according to this invention.

page_text: Figure 2 is a full sized local section on the line 2-2 Figure 1 and
Figure 3 is a section on the line 3-3 Figure 2.
a is the upper backbone and the lower one-e is a bar carrying the saddle at
its upper end and having its lower end pivotted to arms d fixed to the bearing of
the pedal axis. This bearing is connected to the bearing of the driving wheel by
radius reds e. The bearing of the driving wheel is connected to the rear end of the
backbone a by bars f entering slots a' in it and secured by a bolt and nut g passing
through a distance piece g'. The bar c has studs c c fixed to it which are hung
from the two branches of the bar a by steel springs h encircling indiarubber tubes jj
and kk upon the bar a and studs c¹ respectively. The bar b is connected to the
bar e in a similar manner to the bar a."
с
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 I wish it
to be understood that I do not claim broadly supporting the bar carrying the saddle
and pedals by springs from the frame but what I claim is :-
1. The combination of the bar with the bifurcated backbones substantially as
described.
2 The combination of the studs upon the bar with supporting springs on the
backbone substantially as described.
3. The arrangements for supporting the bar substantially as described and shown
in the drawings.
