Improvements in or connected with Tyres for the Wheels of
Velocipedes or other Road Carriages.
I, ARTHUR BAGSHAWE, of No. 4A, Upper Thames Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or connected with tyres for the wheels
of velocipedes or other road carriages.
The wheels of velocipedes, motor-cars or other road carriages, are at the present
time, generally furnished with inflated tyres as admittedly they have the best
cushioning effect, but tyres of that character are, as is well known, liable to
puncture, and a punctured tyre sometimes renders a vehicle useless for the time
being, giving rise to considerable trouble and sometimes resulting in serious
accidents.
Now, the object of the present invention is to obtain a tyre which, whilst
possessing some or all of the advantages of the pneumatic tyre, will, at the same
time; remain substantially unaffected by a puncture, added to which the trouble-
some operation of inflating the tyre will be avoided.
In carrying the invention into effect, a length or lengths of wire of round, flat,
or other convenient section is or are coiled into the form of one or more helical
springs with the coils slightly separated and the spring or springs is or are laid
around the rim of the wheel in a recess of U or other suitable shape.
The wire of which the spring or springs is or are formed may be of steel, bronze,
brass. aluminium, or other suitable metal, and the springs may be hardened or
toughened.
The coil or coils may be fastened to the rim or felloe in any convenient manner,
such, for example, by a length of wire passed through the coil and its ends twisted
together, or by a number of separate clips or fastenings, each embracing a thickness
of the wire forming the coil and passing through an opening in the felloe and
turned over on the inside thereof, or any other suitable fastening device might be
employed for the above purpose.
Over the entire length of the coil is placed a covering or wearing surface of
india-rubber, canvas, leather or other suitable material, which, whilst assisting to
retain the coil in position, at the same time, excludes dirt and extraneous matter,
whilst it also affords an even running surface.
This covering is fixed to the felloe by lacing, by the aid of cement, or it may
be otherwise fastened in position, but it is preferably strained over the wire coil
so that it may present an even surface.
By the means hereinbefore described, a type is obtained which is exceedingly
durable, inasmuch as the wire coil is practically indestructible, and the cover or
running surface is not rendered useless by a cut or puncture, whilst the device is
inexpensive and easily repaired should it meet with injury.

Velocipedes or other Road Carriages.
I, ARTHUR BAGSHAWE, of No. 4A, Upper Thames Street, in the City of London,
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 :-
My said invention relates to improvements in or connected with tyres for the
wheels of velocipedes or other road carriages.
The wheels of velocipedes, motor-cars or other road carriages, are at the present
time, generally furnished with inflated tyres, as admittedly they have a good
cushioning effect, but tyres of that character are, as is well known, liable to
puncture, and a punctured tyre sometimes renders a vehicle useless for the time
being, giving rise to considerable trouble and sometimes resulting in serious
accidents.
Now, the object of the present invention is to obtain a tyre which whilst
possessing some or all of the advantages of the pneumatic tyre, will, at the same
time, remain substantially unaffected by a puncture, added to which the trouble-
some operation of inflating the tyre will be avoided.
In carrying the invention into effect, a length or lengths of wire of round, flat
or other convenient section is or are coiled into the form of one or more helical
springs with the coils slightly separated and the spring or springs is or are laid
around the rim of the wheel in a recess of U or other suitable shape.
The wire of which the spring or springs is or are formed may be of steel, bronze,
brass, aluminium, or other suitable metal, and the springs may be hardened or
toughened.
The coil or coils may be fastened to the rim or felloe in any convenient manner,
such, for example, by a length of wire passed through the coil and its ends twisted
together, or by a number of separate clips or fastenings, each embracing a thickness
of the wire forming the coil and passing through an opening in the felloe and
turned over on the inside thereof, or any other suitable fastening device might be
employed for the above purpose.
Over the entire length of the coil is placed a covering or wearing surface of
india-rubber, canvas, leather or other suitable material, which, whilst assisting to
retain the coil in position, at the same time, excludes dirt and extraneous matter,
whilst it also affords an even running surface.
This covering is fixed to the felloe by lacing, by the aid of cement, or it may
be otherwise fastened in position, but it is preferably strained over the wire coil
so that it may present an even surface.
And, in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a transverse section of the rim or felloe and adjacent parts of a
wheel having the present invention applied thereto.
Figure 2 is a longitudinal section thereof.
Figure 3 is an underside view thereof illustrating the method of fastening the
cover in place.
Figure 4 is a similar view to Figure 1, but with the cover removed.
Figure 5 is a similar view to Figure 1, representing a slight modification

page_text: Figure 6 is a similar view to Figure but with the cover removed.
Figure 7 is a detail view of parts thereof, drawn to an enlarged scale, and
Figure 8 is a transverse section representing a portion of the rim or felloe of the
wheel and coil or tyre illustrating a modification in the method of fastening the
coil in position.
In the several figures, like parts are indicated by similar letters of reference.
Referring to Figures 1 to 4, a represents the rim or felloe of the wheel and a¹
represents the spokes thereof which are secured thereto in the ordinary way, and b
represents a length of round wire, or it might be of flat or other convenient section,
coiled into the form of a helical spring with the coils slightly separated which is
laid around the rim or felloe a of the wheel in the recess formed thereby which is
approximately of U shape although it might be of other suitable shape.
The ends of the coil or spring b are fastened together by any suitable means,
such, for example, as the clip & represented at Figure 2 and the device may be
fastened to the rim or felloe a in any convenient manner, but in this example it is
secured thereto by means of a length of wire c passed entirely through the coil b
and at its ends twisted together as represented at c in Figure 2, or, in some cases,
the fastening c may be entirely dispensed with and the tension of the coil aided
by the cover hereinafter referred to relied upon to hold it in place in the rim
or felloe.
The wire of which the spring b is formed may be of steel, bronze, brass,
aluminium, or other suitable metal, and the spring may be hardened or toughened,
if found necessary.
Over the entire length of the coil b is placed a cover d of india-rubber, canvas,
or other suitable material which constitutes a wearing surface or tread to the tyre,
and this cover d whilst assisting to retain the coil b in position at the same time
excludes dust and other extraneous matter, and also affords an even running
surface.
The covering d is fixed with the felloe a by means of a lacing d2 which engages
hooks carried by the cover d and by the aid of which it is efficiently strained
over the wire coil b so that it will present an even surface, or the cover may
be fastened in position by other suitable means, such, for example, as those herein-
after described, but it is preferably in all cases strained over the wire coil b.
In lieu of forming the coil b of a single length of wire it may be formed of
several lengths, that is to say, the coil may be made up of several segments but in
such case the ends of adjacent segments would be united by means of a joint such,
for example, as that 61 represented at Figure 2.
In the example given at Figures 5, 6, and 7, the device is substantially the same
as that herein before described, but in this case the coil b of wire is secured to the
felloe a by means of a number of separate side clips or staples e each embracing
a thickness of the wire forming the coil b and passing through an opening a in
the rim or felloe « to the inner circumference thereof where it is turned over or
clenched as represented more particularly at Figure 7.
In this example also, the cover d instead of being secured in position by means
of lacing is at its edges caused to overlap at d* where the overlapping parts are
cemented together by any suitable cement."
In lieu of securing the cover in the manner above described, the edges thereof
may be respectively cemented to the inner faces of the edges of the rim.
In the example given at Figure 8, the device is substantially the same as that
represented at Figure 5 with the exception that in lieu of the clips c being arranged
at each side of the rim or felloe a they are placed centray thereof so that they
form one continuous line around the coil b.
By the means hereinbefore described, a tyre is obtained which is exceedingly
durable inasmuch as the wire coil b is practically indestructible and the cover of
the running surface d is not rendered useless by a cut or puncture, whilst the
device generally is inexpensive and easily repaired should it meet with injury.
A further advantage of the present invention is, that, with tyres constructed in

page_text: accordance with the same, covers made for use in connection with many other
forms of tyre may be used in connection therewith.
It will be obvious that the details of construction of the device may be further
more or less varied without departing from the spirit of the invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
A wheel tyre comprising a helical coil or coils of wire lapped around the rim
or felloe and there fastened by means of a length of wire, clips or otherwise and
enclosed in an india-rubber or other suitable cover or tread, substantially as herein
shown and described and for the purpose stated.
