PROVISIONAL SPECIFICATION.
Improvements in Bicycles, Tricycles, Motor Cars, and such like
Vehicles, for the purpose of Neutralising Vibration.
I, JOHN GARDNER, of the Steamship "Yarrow" trading between Dublin and
Silloth, of North Wall, Dublin, Engineer, do hereby declare the nature of this
invention to be as follows;-
-
This invention relates to improvements in cycles, motor cars, and such like
vehicles and has for its object the neutralising of, or reducing to a minimum
vibration.
In carrying out my said invention I form the individual limbs of the forks which
carry the wheels, of suitable tubes or cylinders in which slide suitable piston rods
which impinge against india rubber balls, spiral springs or other suitable rebound-
ing substance fixed in the tube. The free ends of the piston rods are then rigidly
connected to the hub of the wheel so that any vibration in the said wheel will be
absorbed by the elastic or rebounding substance against which the piston rods act.
Thus by this arrangement means are afforded whereby an elastic or springy
medium is introduced between the wheels and the frame of the machine which will
as stated, absorb effectually any vibration, without imparing the rigidity and
strongth of the frame.

Improvements in Bicycles, Tricycles, Motor Cars, and such like
Vehicles, for the purpose of Neutralising Vibration.
I, JOHN GARDNER, of the Steamship "Yarrow," trading between Dublin and
Silloth, of North Wall, Dublin, Engineer, 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, motor-cars, and such like
vehicles, and has for its object the neutralising of, or reducing vibration to a
minimum.
The invention consists in arranging a piston rod in a suitable tube so as to
impinge against a series of india-rubber balls, spiral springs, or other suitable
rebounding substance fixed in the tube.
Or instead of a piston rod, one tube may be made to slide telescopically in an
outer tube, suitable lugs and bolts being used to prevent the tubes parting cuch

page_text: This device is interposed in any convenient manner between the frame work
and the wheels of cycles, motor-cars, carriages, or other vehicles, to which the
invention may be found applicable.
The nature and application of my improved spring contrivance will be more
readily understood by reference to the accompanying drawings, in which,
Fig. 1, illustrates its application to the bottom plate of an ordinary carriage
spring, or the frame work of a motor car, or other wheeled vehicle.
A represents the bottom plate of an ordinary carriage spring, or it may be the
rigid frame work of any wheeled vehicle,-B is the axle box, and my invention is
shewn interposed between.
It will be perceived that the piston C slides telescopically in the tube D and
impinges against the series of india-rubber balls, which acting one against the
other, afford considerable elasticity, and effectually absorb vibration.
Lateral rigidity may be cusured by increasing the width of the terminal plates E
at the base ends of the spring contrivance.
Fig. 2, illustrates the application of my invention to the fork of a bicycle, and,
Fig. 3, its application to the saddle pillar of a bicycle.
In Fig. 2, an inner tube C instead of a piston rod is arranged to slide teles-
copically in the outer tube D and lugs bare provided through which a bolt d
passes for the purpose of preventing the tubes parting from each other.
It is obvious that spiral springs, or other rebounding substance may be used
in the outer tube D instead of the india-rubber balls shown.
In Fig. 3, the arrangement for adjusting the height of the saddle is not inter-
fered with, since my improved spring contrivance slides bodily in the ordinary
Baddle pillar F.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declaro that what I
claim is:
:―
In combination with cycles, motor-cars, and such like vehicles, the use and
application of a spring contrivance consisting of a piston rod impinging against a
series of india-rubber balls, spiral springs, or other rebounding substance arranged
in a tube, or of one tube sliding telescopically within another, for the purpose and
in the manner substantially as herein specified and illustrated in the accompanying
drawinga.
