PROVISIONAL SPECIFICATION.
Improvements in Velocipedes.
I, PERCIVAL WILLIAM DAVIS, of No. 54 Frith Street, Soho, in the County of
Middlesex, Whip and Stick Mounter, do hereby declare the nature of this invention
to be as follows:-
This invention relates to tricycle velocipedes of that class in which a single steering
wheel is placed at the front of the machine and two driving wheels are placed at the
end thereof the motion being communicated thereto by means of a chain and chain
wheels from pedals located at a suitable part of the longitudinal frame and the object
of the present invention is to lessen the vibration or jolting of the frame of the
machine and consequently of the rider in passing over rough and uneven roads.
For this purpose the bearings of the axle of the rear wheels instead of being
connected rigidly with the longitudinal frame of the machine are connected therewith
by means of a bow or flat band spring or springs which are at one end attached
to the said bearings and at the other end are connected with the rear of such
longitudinal frame in such manner that the rear end of the frame of the machine
is supported on such spring or springs.
To the bearings of the said axle is or are connected a stay rod.or rods the
opposite end or ends of which stay rod or rods is or are hinged or connected to
the longitudinal frame or to the chain wheel bracket in such manner as to allow
of the vertical movement of the rear wheels and axle in relation to the frame.
The saddle is supported upon a standard or vertical limb of the longitudinal
frame in the ordinary manner, and, if desired, this standard may be connected with
the sleeve or bearing of the steering spindle by means of a removeable stay.
If desired, the axle of the rear wheels may be divided, in which case, the two
parts would be mounted in suitable bearings carried by the before mentioned spring
or springs.
A spring is interposed between the steering fork and the sleeve or bearing of
the frame in which the steering spindle works, such parts being so arranged relatively
to each other that the spindle is capable of slight vertical movement in its said
sleeve or bearing.
Instead of connecting the frame to the bearings of the driving wheels, as
hereinbefore stated, by a bow or flat spring or springs, I may substitute coiled
springs for the latter.

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 tricycle velocipedes of that class in which a single steering

at one end connected whilst near to the balance gear c* the axle c' is supported in
other bearings f* which are steadied by stay rods fat one end hinged thereto and at
the other end hinged to the chain wheel bracket or fork a¹.
In this arrangement, the downward continuation of the vertical limb a' of the
longitudinal frame a. is dispensed with, and stay rods 9. at one end hinged to the
chain wheel bracket or fork a¹ and at the other end hinged to the cross bar a* are
employed in lieu thereof, whilst the saddle post a³ is connected with the sleeve or
bearing a* of the steering spindle &' by means of a stay a** as hereinbefore described
with respect to Figures 1. and 2, but in this case the stay is a fixture.
い
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 :-
:-
In a velocipede of the character herein described, connecting the bearings of the
axle of the rear driving wheels with the rear of the longitudinal frame by means
of flat springs and stay rods, in manner substantially as herein shown and described.
Dated this 3rd day of April 1890.
