We JOHN HARRINGTON of The Enamel and Cradle Spring Works, Coventry in the
County of Warwick, Manufacturer, and JOHN HOPPER of 364 Fullam Road in the
County of Middlesex, Manager do hereby declare the nature of this invention to be as
follows:-
.
The invention has for its object a novel adaptation and arrangement of springs and
their connections between the lower end of the fork and the axle or pin of the wheel
in order to provide an elastic connection between the fork and wheel which shall be so
controlled that the wheel shall in its rise and fall be caused to move in a vertical plane
situated centrally between the arms of the fork thereby preventing the wheel from
rubbing against one or other of the said arms by the unequal action of the springs.
For this purpose we pivot to the lower end of each arm of the fork a link, these
links carry the wheel pin or axis at or near their outer ends; to each of these links we
connect one end of a spring which has an eye formed thereon for that purpose, the
other end of the spring is fixed rigidly to the lower end of the fork.
These springs are preferably formed of wire or rod metal which is formed with
vertical coils at one end, from the upper and lower parts of which, arms extend forward
to the points of connection before referred to.
Other descriptions of springs may however he employed.

Improvements in Bicycles, Tricycles, and other Velocipedes.
We JOHN HARRINGTON of The "Enamel and Cradle Spring Works," Coventry in
the County of Warwick Manufacturer and JOHN HOPPER of 364 Fulham Road in the
County of Middlesex, Manager 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 :-
The invention has for its object a novel adaptation and arrangement of springs and
their connections between the lower end of the fork and the axle or pin of the wheel in
order to provide an elastic connection between the fork and wheel which shall be so
controlled that the wheel shall in its rise and fall be caused to move in a vertical plane
situated centrally between the arms of the fork thereby preventing the wheel from
rubbing against one or other of the said arms by the unequal action of the springs.
For this purpose we pivot to the lower end of each arm of the fork a link, these
links carry the wheel pin or axis, at or near their outer ends, or at other convenient
position to each of these links we connect one end of a spring which has an eve
formed thereon for that purpose, the other end of the spring is fixed rigidly to the
lower end of the fork.
These springs are preferably formed of wire or rod metal which is formed with
vertical coils at one end, from the upper and lower parts of which, arms extend forward
to the points of connection before referred to.
Other descriptions of springs may however be employed.
And in order that our said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view and Figure 2 is a front view and Figure 3 is a plan partly
in section of parts of the steering or other non driving wheel of a bicycle, tricycle or
other velocipede and the lower parts of the fork carrying the same showing our
invention applied thereto. Figures 4 and 5 are similar views showing our invention
applied to one side of the driving wheel of a bicycle or other velocipede..
In all the figures like parts are indicated by similar letters of reference a a represent
the lower ends of the arms of the fork, represents the hub of the wheel and c the
wheel pin or axis..
In carrying our invention into effect we pivot at d to the lower end of each arm a
of the fork a link d, these links carry the wheel pin or axis e at or near their outer
ends or at any convenient position in the length thereof to each of these links d we
connect one end of a spring e which has an eye el formed thereon for that purpose, a
screw pin being passed through said eye and screwed into the link d, the other end
of the springe is fixed rigidly to the lower end of one arm a of the fork in any
suitable manner, the method shown in the drawings being very simple and convenient
and which is as follows; the straight end of the springe is passed through an eye or
clip the screwed ends or stud of which are or is passed through a hole in the
lower end of an arma and there held in position by a nut which by the aid of the

page_text: clip firmly binds the end of the spring against the lower end of the arm a, and in
order to prevent the possibility of the straight arm of the springe working on the axis
of the clip we pass the end of the said straight arm of the spring e between fixed
studs a¹.
These springs e are preferably formed of wire or rod metal and are formed with
vertical coils at one end, from the upper and lower parts of which, arms e³ et
extend forward to the points of connection before referred to.
Other descriptions of springs may however be employed.
1
In the application of our invention shown at Figures 1, 2, and 3 the wheel pin or
axis e is fixed in position on the links d by means of screw nuts e¹ but in the applica-
tion shown at Figures 4 and 5 the wheel pin or axis passes entirely through the links d
and has cranks or a chain wheel or chain wheels fixed on the outer ends thereof; in
this case the links d carry, or are formed with ball, or other suitable bearings 3 for
the wheel pin or axis e to run in.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. The peculiar adaptation and arrangement of springs and their connections
between the lower end of the fork and the axle or pin of the wheel of a bicycle,
tricycle or other velocipede substantially as herein shown and described and for the
purpose stated.
2. Supporting the wheels of a bicycle, tricycle or other velocipede in links which
are pivotted at one end to the lower ends of the arms of the fork and at the other end
are acted upon by springs substantially as herein shown and described and for the
purpose stated.
