Improvements in connection with Pneumatio Tyres.
I, ADRIAN PIERRE JORDAN of 62 Dalston Lane, London N.E., and 5 The
Grove, High Road, Leytonstone, in the County of Essex, Hosier and Athletic
Outfitter, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved device for attaching to any and every kind
of pneumatic tyre, as used upon bicycles, tricycles and similar velocipedes, the object
whereof being ostensibly for the prevention of side and backward slip of said tyre,
when travelling upon wet or slippery roads or paths, and more particularly when
the machine is describing sharp curves.
My invention consists of the employment of any number of straps or strips of
leather, cowhide, canvas or other fabric, or other tough and flexible material, which
may or may not have been previously subjected to a process for rendering the same
waterproof, and which may be of any suitable width, and of such a length as to be
capable, by a suitable means of adjustment, of surrounding or partly surrounding
laterally, a fully inflated tyre, and the rim of the wheel upon which it is mounted,
regardless of the cross sectional dimensions thereof, and upon each of said strips or
straps, centrally of their length or thereabouts, or such part thereof as would occur
or any other suitable means,
at the tread of the wheel, I attach by rivetting burring.
two or more metallic projections (preferably four) which extend from that which is
intended to be the outer surface. The said projections may be conical, pyramidal,
or any other shape or contour desired.
Upon either or both ends of said strips or straps I connect by any suitable means,
one or more eyes or eyelets, so that any number of said strips or straps may be fixed
at suitable intervals of the circumference of the tyre by the means of a lace or laces
engaging with the said eyes or eyelets, or these may be caused to engage with studs
or projections upon the rim of the wheel where such have been provided. Or I
may form an eye or eyelet or eyes or eyelets at one end of said strips or straps, and
upon the opposite end a hook or hooks tag or tags or other projection or projections
capable of engaging with the said eyes or eyelets. Or I may attach at each end of
said strips or straps a hook or hooks tag or tags and arrange that these engage
with the spokes of the wheel, or any other suitable means may be employed for
adjustably connecting together the ends of said strips or straps by which these may
be connected to and be fixed upon any size tyre, without the need of alteration
thereto for that purpose.
Before attaching the said strips or straps to the tyre in either of the manners
herein provided, it would be desirable that the air bag should be partly deflated, in
order that when the desired number have been fastened in position, these would be
stretched taut to their full limit when the tyre was again inflated, and so rendered
immovable during use, notwithstanding the strain that would be imposed thereon by
reason of the metallic projections cutting into the road or path, whereby side or
backward slip is entirely prevented.

I, ADRIAN PIERRE Jordan, of 62 Dalstou Lane, London N.E., and 5 The
Grove, High Road Leytonstone, in the County of Essex, Hosier and Athletic
Outfitter 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 :-
My invention relates to an improved device for attaching to any and every kind
of pneumatic tyre, as used upon bicycles, tricycles and similar velocipedes, the
object of my said invention being ostensibly for the prevention of side and backward
slip of said tyre when travelling upon wet or slippery roads or paths, and more
particularly when the machine is describing sharp curves.
In order that my invention, and the several alternative methods of arranging the
same, and the manner of its application to any form of tyre may be clearly under-
stood, I have hereunto appended a sheet of drawings, in which,
Figs. 1 and 2 are plan and edge view respectively of one of the strips or straps,
the application of which in any desired number to the wheels of velocipedes in the
manner hereinafter explained forms the subject of my invention.
Fig. 3 is an outer view of part of a wheel rim and tyre to which my invention has
been applied.
Fig. 4 is a cross section of Fig. 3.
Figs. 5, 6 and 7 are views illustrating some of the means I may employ for
connecting together the ends of said strips or straps.
I carry my invention into effect by constructing of leather, oxhide, canvas, or
other woven fabric, or other tough and flexible material, strips or straps A, which
may or may not, according to their texture, have been previously subjected to a
process for rendering the same waterproof, which may be attained by coating the
outer or inner sides or both thereof, with a solution of rubber or rubber composition.
The said strips or straps may be of any desired width, and of such a length as to be
capable of surrounding or partly surrounding, laterally at any desired angle a fully
inflated tyre B, and rim C of the wheel upon which they are to be mounted,
whatever may be the cross sectional dimensions thereof, and upon that face of said
strips intended to be the outer when in use, and centrally of their lengths or
thereabouts, or such part thereof as would occur at the tread of the wheel, I attach
to each by rivetting or other suitable means, two or more pyramidal, conical or
other shaped metallic projections or studs D, preferably of hardened steel, which
stand up from the faces of said strips or straps a sufficient distance to afford a firm
grip upon the road or path when in use, for the prevention of side and back slip of
the tyre.
The said strips or straps may be provided with an eyelet or eyelets E at each
end thereof so that these may be laced together as at Fig. 5, when surrounding the
tyre and rim at right angles thereto as at Figs. 3 and 4, or diagonally or obliquely
thereto as shewn by the dotted outline in the same figure. Or I may for the same
purpose form one or more eyelets E in one end and connect a hook or hooks F to
the other, so that these may engage with each other as at Fig. 6. Or I may fix
upon one end a stud or studs G, and upon the other a hook or tag or hooks and
tags H, in order that these may engage with each other as at Fig. 7. Or if the
nature of the material of which Å is made will permit of this, I may attach to one
end a buckle J as at Fig. 1, and cause this to engage with the opposite end in the
usual way. Or I may arrange that the eyelets E or the hooks or tags H may
engage with studs upon the inner periphery of the rim C. Or I may connect to
each end of the said strips ordinary flat hooks and cause these to engage with the 5
spokes of the wheel, or I may employ any combination of these or other suitable

page_text: means for attaining the same ends, without in any way altering the rim for that
purpose.
The air bag of the tyre having been partly deflated, or if empty partly inflated,
any desired number of the said strips or straps may be placed around C and B at
right angles thereto and equidistant apart as at Fig. 3, or obliquely, and engaging
with any two of the spokes as shewn by the dotted outline in the same figure, and
be fastened thereto by any of the means herein provided, and when these are all in
position with the studs D equally divided over the centre of the tread of the wheel,
the air bag may be fully inflated, and all the bands or straps A be tightened, and
held in position thereby, but in order to guard against the possibility of these
slipping backward during the rotation of the wheel, I may fix upon the inner
surface of each, and covering the rivetted or burred ends of the studs D, a strip of
rubber K as shewn at Fig. 2, or an extra coating of rubber solution at this part may
have the same effect, and to prevent the said bands or straps from creeping or
slipping sideways of the tyre B, by which the studs D would be removed from the
tread of the wheel, I may fix upon each band or strap by stitches, cement, rivets or
other means, a bifurcated plate L as at Fig. 7, and arrange that these engage with
the spokes of the wheel, care being taken that each strap or band when at right
angles to the tyre was so placed as to behind and not in front of the spoke
embraced by the plate L thereon, having regard to the direction of the travel of
the wheel.
By this simple and inexpensive contrivance the backward slip of the wheel when
racing upon a straight but slippery road, or side slip when the wheel is describing
a sharp curve is entirely prevented, by reason of the bite upon the road afforded
by the studs D, and the very slight addition to the weight of the machine can be
measured by ounces, and this would be more than compensated for by the great
confidence and security enjoyed by the rider, thus enabling him to safely put
greater energy into the propulsion of the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that I do not
claim the exclusive use of metallic projections or studs for the prevention of slip in
pneumatic tyres, except such be mounted upon and connected to straps or bands
capable of being easily attached to, and detached from, the tyre of the wheel, there-
fore what I claim is.
1st. In combination with any type of pneumatic tyre and rim, the application
thereto and at any angle therewith of straps or bands provided with two or more
studs or projections, and fastened in position thereon by any of the means herein
provided, substantially as and for the purposes described, and shewn by the
appended drawings.
2nd. In combination with any type of pneumatic tyre and rim, the construction
and use of any number of straps or bands A of leather, hide, canvas or other
material or fabric, with or without having been previously rendered waterproof and
with or without a strip K connected thereto each having two or more metallic
projections or studs D rivetted or otherwise fixed thereon, and standing upwardly
therefrom, and with or without being provided with a bifurcated plate L, stitched,
cemented, rivetted or otherwise connected thereto, and the manner of employing
the said strips surrounding at any desired angle the rim C and tyre B, and fastened
in position thereon by any of the means herein provided, substantially as and for
the purposes herein described and shewn by the accompanying drawings.
Dated this 30th day of November 1893.
