PROVISIONAL SPECIFICATION.
An Attachment for Protecting the Tyres of Cycle and other
Wheels.
I, PAUL TAYLOR, of 45 Constitution Hill, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to means for the dislodging of puncturing objects, such as
thorns, brambles, nails, glass and the like picked up during running, from the
pneumatic tyres of cycle and other like wheels, and consists in the employment in
close proximity to the surface of the tyres, of intercepting guard wires or bars,
which come within the path of objects which may be picked up by the tyre in
running.
Thus, an object first picked up by a tyre usually only penetrates to a very
slight distance into the cover, and is then carried round from left to right, and
on the passing of the wheel again over it, then the mischief occurs by the said
puncturing object being driven fully home into and through the tyre.
Now if such objects can be dislodged immediately after their initial attachment,
then puncturing is avoided, and to accomplish this, I employ expedients (as herein-
after described) attached to the fixed framing, parts of which shall come within or
cross the general plane of the motion of the wheel.
In carrying out my invention in connection with a front wheel, I take two semi-
circular clips, with opposite flanges or ears, and I attach the same to the two
opposite sides of the branches of the front fork, adjacent to, or immediately under,
the crown,
and which clips may be secured in position by cross screws, pins or
other means.
Between the flanges or lugs of these said clips, intercepting guard wires are
directed or stretched with the same coming in close proximity to the outside
periphery of the tyre, so that should the tread of the tyre pick up an object on its
road of traction, the same is brought against the guard wires, and is then and
thereby dislodged.
In this said attachment or thorn catcher, two dislodging wires or bars are
employed, one forward of the other, and they may be arranged if necessary, at
different distances from the tyre, so that should the object picked up be missed by
the one dislodgement guard, it is caught by the other.
The said guards may if necessary be hung hinge-wise, and stopped at a slight
angle, so as not to come in direct or actual contact with the tyre.
The guards may be made semi-circular or concaved to the cross and outside
contour of the tyre, so that impediments picked up by parts approximate to the
sides will be removed, as well as those picked up by the tread.
The clip parts may be made in the form of attached brackets, or they may
be made in the form of horse-shoe spring-clips, with the terminal ends turned
outwardly into ears, from which the dislodging wires of the appliance come.
Instead of employing two wires, I may employ only one dislodging or guard
wire.
In carrying out my invention in connection with the back wheel, I employ two
band clips, with their free ends brought nearly together, and with the ends of the
dislodging wire or rod passed between or connected to them by travelling nuts
taking upon screwed ends of the said dislodging wire.
The spring bands are of an elliptical shape, and embrace the frame members
coming on the two opposite sides of the wheel.

page_text: The thorn catcher or dislodger is placed immediately above the plane of the
outer periphery of the tyre of the wheel.
Instead of employing spring clips, I may use rigid attachable and detachable
brackets, whilst the brackets or clips are adjustable, and so also are the guard wires
themselves.

COMPLETE SPECIFICATION.
An Attachment for Protecting the Tyres of Cycle and other
Wheels.
I, PAUL TAYLOR, of 45 Constitution Hill, in the City of Birmingham,
Manufacturer, 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 relates to means for the dislodging of puncturing objects, such as
thorns, brambles, nails, glass and the like picked up during running, from the
pneumatic tyres of cycle and other like wheels, and consists in the employment in
close proximity to the surface of the tyres, of intercepting guard wires, bars, or
equivalents having attachments, and which said guard wires come within the path
of objects which may be picked up by the tyre in running.
.
Thus, an object first picked up by a tyre usually only penetrates to a very slight
distance into the cover, and is then carried round from left to right, and on the
passing of the wheel again over it, then the mischief occurs by the said
puncturing object being driven fully home into and through the tyre.
Now if such objects can be dislodged immediately after their initial attachment,
then full puncturing is prevented or avoided, and to accomplish this, I employ
expedients (as hereinafter described) attached to the fixed framing, parts of which
shall come within or cross the general plane of the motion of the wheel.
In carrying out my attachment I take two clips, with opposite flanges or
ears and I attach the same to the two opposite sides of the branches or members
of the fork, adjacent to or immediately under, the crown, (in the case of a
front wheel) and which clips may be secured in position by cross screws, pins or
other means.
Between the flanges or lugs of these said clips, intercepting guard wires are
directed or stretched, with the same coming in close proximity to the outside
periphery of the tyre, so that should the tread of the tyre pick up an object on
its road of traction the same is brought against the guard wires, and is then and
thereby dislodged
In this particular form of attachment or thoin catcher, one dislodging wire
or bar is preferably employed, although I may if necessary employ two, one
forward of the other, and they may be arranged at different distances from the
tyre, so that should the object picked up be missed by the one dislodgment guard,
it is caught by the other.
The said guards may if necessary be hung hinge-wise, and stopped at a slight
angle, so as not to come in direct or actual contact with the tyre.
The guards may be made semi-circular or concaved to the cross and outside
contour of the tyre, so that impediments picked up by parts approximate to the
sides will be removed as well as those picked up by the tread.
The clip parts may be made in the form of attached brackets, or they may be
made in the form of spring clips, with the terminal ends turned outwardly into
cars, from which the dislodging wires of the appliance come.

page_text: The thorn catcher or dislodger is placed immediately above the plane of the
outer periphery of the tyre of the wheel.
Instead of employing spring clips, I may use rigid attachable and detachable
brackets, whilst the brackets or clips are adjustable, and so also are the guard
wires themselves.
Figure 1 of the accompanying drawing represents in perspective, the front
wheel of a cycle having a puncture-preventative means attached to the branches
of the forks according to my invention.
Figure 2 represents a part of a machine with another form of puncture-
preventative means attached to the embracing frame members of the hind wheel.
Figure 3 represents a complete bicycle showing the puncture preventative means
applied to other parts of the machine, viz. the stays of the mud guards.
Figure 4 represents a topside plan, partly in section of the front wheel puncture-
preventative means.
Figure 5 is an end view of the same whilst Figure 6 is a front elevation thereof
looking towards the ears or front flanged parts.
Thus, in Figures 1, 4, 5 and 6 a, a are band clips with free and flanged ends ',.
brought nearly together and having piercings a³, at their middle parts, where--
through the ends or the screwed ends 63, of dislodging bridge wires b, take, and are
there secured across and in close proximity to the periphery of the wheel by stop
and fixing nuts c, d, the former coming upon the inner side of the flanges a', and
the latter upon the outer side.
In fixing on the puncture-preventative means with attachments, first pass the
clips a, around the branches e, e', of the fork e, then pass the ends 6, of the wires,
through the eyes or piercings a², of the flanges a', with the blocking nuts c,.
screwed back full home. Then rotate back the nut c, and rotate forward the
nut d, or rotate the said nuts c and d, in opposite directions for adjustment,.
when the clips are affixedly secured to the branch or framing members, of a
machine and the dislodging wires are brought up close to and across the periphery
of a tyre.
Figure 7 represents a topside plan, partly in section of a puncture preventative
means for use in connection with a back wheel, whilst Figure 8 is an end view of
the same.
✓ are semi-circular bracket clips, with end flanges or ears, having
piercings, wherethrough the screwed ends 62, of the two dislodging and
parallel wires b, b, take, and are secured by drawing-up screw nuts d, taking upon
the outsides of the said flanges of the clips. 9 are the branches or members of
the back fork (see Figure 2).
In making the connection, pass the ends of the wires through the holes or
piercings in the opposite bracket clips then screw home the nuts d, when the
wires b, are drawn taut and the clips f, are fixedly secured to the members g, by
the wires, which lie within the path of any puncturing objects which may be
carried round by the tyre on its road of traction.
It will be obvious that either of the puncture-preventative means may be used
indifferently for both back and front wheels by making only slight changes.
If necessary the wires may be inade to follow the contour of the tyres and in
such an event, then they are made to follow the figure represented in dotted lines.
in Figure 4.
Figure 9 represents a front elevation of another form of attachment, whilst
Figure 10 is a plan of the same.
In this form of any invention, the clips are secured by independent cross pins,
which when screwed up, draw the said clips upon the frame members of a machine
independent of the dislodging wires.
a are the clips and are cross pins passing through holes a', in the opposite
ears a thereof, whilst the screwed ends 2, of the wires b, pass through holes a³ of
ears at, and are drawn up taut by screw nuts d, located upon the outsides of the
said flanges a*.

page_text: It is further obvious that instead of employing wires, I may use rods, or catgut
or equivalent, or I may employ bands in lieu of wires, rods or the like.
The application or attachment of the puncture-preventing means to other parts
of cycle framings, such as to the mud guards stays as represented in Figure 3
differs in no essential particular from its attachment to the front forks or the like
as herein described.
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 what I
claim is :-
First. In puncture-preventing means for pneumatic cycle tyres, employing in
connection with the dislodging wires or equivalent of the same, machine-member
embracing and wire end carrying band clips, substantially as herein described and
set forth in Figures 1, 4, 5 and 6.
Secondly. In puncture-preventing means for pneumatic cycle tyres, employing
in connection with the dislodging wires or equivalent of the same, framing-
embracing and wire-carrying bracket clips, substantially as described and set forth
in Figures 2, 3, 7 and 8.
Thirdly. The combination with the puncture preventing attachments referred to
in the preceding claims, of stop and fixing drawing-up nuts, substantially as
described and set forth in Figures 1 to 8.
Fourthly. In attachment or carrying clips for puncture preventing means, the
general construction, arrangement and combination of the parts substantially as
described and set forth in Figures 9 and 10.
