PROVISIONAL SPECIFICATION.
Improvements in the Construction of Wheels applicable to various
purposes.
JAMES ALFRED BRIGGS of 30 Dewhurst Road Hammersmith London W.
Electrical Engineer & WILLIAM COLLINS, Journalist, of 100 Sussex Road
Seven Sisters Road London N. do hereby declare the nature of this invention to
be as follows:-
These improvements relate to the application & fitting of springs on near or about
the periphery or circumference of the wheel & may be used with either one or
more tyres or felloes which tyres or felloes may be arranged either concentricly
or otherwise & may be either rigid or flexible.
The following are the principal forms we propose to use.
(1) A wheel with a rigid or flexible tyre or felloe on the exterior of which tyre
or felloe we apply or attach a continuous helix of elastic or springy material
preferably steel in such manner that the geometrical axis of the helix is concentric
with the tyre or felloe. This helix may be of any section but would commonly
but by no means necessarily or always be of approximately circular or elliptical
section.
(2) Or the springs attached to the said rigidor flexible tyre or felloe may consist
merely of a number of separate & distinct springs each of which springs may form
or be a complete closed figure in itself or may have one or both ends free or fixed,
& may be plane or funicular & have its principal plane either coincident or parallel
with or forming any angle with the plane of the wheel.
(3) Any of the above forms may be used in combination with a second & external
tyre or felloe which may be flexible or rigid & in this case the said springs are
fixed in various ways between the two tyres or felloes. The inner tyre or felloe
may also be connected with the outer tyre or felloe by a number of springs either
straight or approximating thereto.

JAMES ALFRED BRIGGS of 30 Dewhurst Road Hammersmith London W.
Electrical Engineer & WILLIAM COLLINS Journalist of 100 Sussex Road
Seven Sisters Road London N. 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 :—
These improvements relate to the application and fitting of springs (a) on near
or about the periphery or circumference of the wheel (B) & may be used with
either one or inore tyres or felloes (b & c) which tyres or felloes may be arranged
either concentricly or otherwise & may be either rigid or flexible.
The following are the principal forms we propose to use.
(1) A wheel with a rigid or flexible tyre or felloe (B & C) on the exterior of which
tyre or felloe we apply or attach a continuous helix of elastic or springy material
preferably steel in such manner that the geometrical axis of the helix is concentric
with the tyre or felloe. This helix may be of any section but would commonly
but by no means necessarily or always be of approximately circular or elliptical
[Price 8d.]

page_text: section. The said helix may also be either simple or compound i.e. made or one
continuous piece vide Figure 6 or of two or more continuous pieces and one or
more or all of these continuous pieces may have additional or supplementary turns
or twists with a view to increase the range of the springy action vide Figures 1.
2 & 3.
(2) Or the strings attached to the said rigid or flexible tyre or felloe may consist
merely of a number of separate & distinct springs each of which springs may form
or be a complete closed figure in itself vide Figure 4 or may have one or both ends
free or fixed ride Figures 5, & 8 or may be plane or funicular & have its
principal plane or plane of its motion as a spring forming any angle with the plane
of the wheel.
(3) Any of the above forms may be used in combination with a second & external
tyre or felloc (c) which may be flexible or rigid & in this case the said springs are
fixed in various ways between the two tyres or felloes (B & c).
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is
Improvements in wheel tyres substantially as described above.
The use as a tyre of a spring or springs in the helical form or in some form
readily derived therefrom.
(3) The use as a tyre of a number of separate springs each of which may be a
closed figure or may have one or both ends free, may be plane or funicular & is
attached so that its principal plane or the plane of its motion as a spring is at any
angle with the plane of the wheel.
(4) Any form of the above used in combination on outside rigid or flexible tyre.
