PROVISIONAL SPECIFICATION.
Improvements connected with Bicycles, Velocipedes, and other
Road Vehicles.
I, JOHN THOMAS MAYOR, of 21 Park Terrace, Fulwood, Preston, in the
County of Lancaster, Gentleman, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to provide an improved spring cushioning device
between the wheels and framing of a bicycle or other velocipede and although
mainly designed for application to bicycles it is also applicable to other road
vehicles. As applied to the front wheel of a bicycle the improved device consists
of a spiral or helical spring stretched between the extremities of a finger or arm
depending from each extremity of the fork (the said finger or arm being rigidly
fastened thereto) and the free ends of two rocking levers standing in an approxi-
mately horizontal position and pointing forwardly. The depending fingers as
before stated are made fast at their upper ends to the extremities of the two arms
of the fork whilst the rocking levers are free to oscillate thereon the two fingers
and the two rocking levers being connected to the arms of the fork by means of a
common bolt or stud. The wheel axle is supported across and through the two
rocking levers in a position somewhat about midway of the length of the said levers.
Thus the axle of the wheel forms the fulcrum the two springs the resistance or
weight and the downward pressure of the fork the power in relation to the two
rocking levers. The rocking levers are each provided with a suitable stop
relatively to the fork whereby the sweep of the said levers in either direction is
limited to the desired extent.

Improvements connected with Bicycles, Velocipedes, and other
Road Vehicles.
1, JOHN THOMAS MAYOR, of 21, Park Terrace, Fulwood, Preston, in the
County of Lancaster, Gentleman, 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 for its object to provide an improved spring cushioning device
between the wheels and framing of a bicycle or other velocipede and although
mainly designed for application to bicycles it is also applicable to other road
vehicles. As applied to the front wheel of a bicycle the improved device consists
of a spiral or helical spring stretched between the extremities of a finger or arm
depending from each extremity of the fork (the said finger or arm being rigidly
fastened thereto) and the free ends of two rocking levers standing in an approxi-
mately horizontal position and pointing forwardly. The depending fingers as
before stated are made fast at their upper ends to the extremities of the two arms
of the fork whilst the rocking levers are free to oscillate thereon the two fingers
and the two rocking levers being connected to the arms of the fork by means of a
common bolt or stud. The wheel axle is supported across and through the two
rocking levers in a position somewhat about mid way of the length of the said levers.

weight and the downward pressure of the fork the power in relation to the two
rocking levers. The rocking levers are each provided with a suitable stop relatively
to the fork whereby the sweep of the said levers in either direction is limited to the
desired extent.
In the accompanying drawings,
Fig. 1 is a side view of the front wheel and some of the attendant parts of a
bicycle having my said improved spring cushioning device applied thereto.
Fig. 2 shews the device drawn to a larger scale in the position which obtains
when the load on the bicycle is off and,
Fig. 3 the altered position of parts when the load is on.
Figs. 4 and 5 are modifications of the arrangement of the device shewn in the
preceding figs.
A represents the front wheel of the bicycle and B the fork both being of the usual
construction. c is a spiral or helical spring stretched (at Figs. 1, 2, and 3) between
the extremities of the finger or arm d depending from the end of the fork B and
the free end of the rocking lever f. The depending finger d is made fast at its.
upper end to the extremity of the fork B by means of the screw bolt and nut g and
is formed with a stop or catch lip h which meets the upper edge of the fork and
enables the said finger the better to resist the pull of the spring c. The broken
lines at Fig. 2 indicate an arrangement of slotted hole in the upper end of the
finger d which permits of the said finger accommodating itself for attachment to the
ends of the forks of different widths. The bolt g is so formed that whilst fastening
the finger & and the fork B securely together it at the same time allows the rocking
lever to work freely or pivotally thereon. j is the wheel axle which acts a
fulcrum for the rocking lever f
Instead of arranging the rocking levers and springs as above described (with
reference to Figs. 1, 2, and 3) they may be arranged as shewn at Figs. 4 and 5 in
which one end of the spring c-which in the former views is shewn attached to the
free end of a rocking lever f-is attached to the wheel axle j the short lever m
being pivoted at one end upon the said wheel axle and at the other end upon the
bolt g.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improved spring cushioning device consisting of a pair of spiral or helical
springs one on each side of the wheel the said springs being stretched between the
lower extremities of depending fingers fastened behind the wheel axle to the two
ends of the fork and the outer or front ends of a pair of oscillating levers mounted
or fulcrummed on the wheel axle the said oscillating levers having their rear ends
jointed to the two extremities of the fork substantially as hereinbefore described.
Dated this 22nd day of March 1893.
