PROVISIONAL SPECIFICATION.
A New or Improved Means of Securing the Tyres of Cycles without
the use of Cement.
1 JOHN PEARSON of 8 Broom Avenue, Broom Lane, Levenshulme, near
Manchester, Engineer do hereby declare the nature of my said invention to be as
follows:-
This invention relates to means of securing the tyres of bicycles, tricycles,
safeties and other cycles to their rims without the use of cement and whereby
the same can be reversed when worn in order to afford a fresh wearing surface as
desired.
In performing my invention I employ a number of clips or fastenings similar
in cross section to the rim of the machine but having their longitudinal edges
turned inwards so as to afford a firm grip upon the rubber or other tyre to be
secured.
These clips or fastenings are by preference secured to the rim of the cycle by
bolting or screwing the same through holes drilled in the said rim.
By making these improved clips or fastenings of a slightly broader cross section
than that of the rim to which they are to be applied the same are caused to close
and grip the rubber or other tyre on being drawn or screwed home to their seats in
the said rim.
Instead of turning inwards the longitudinal edges of these improved clips or
fastenings the same can be formed with a swell or enlargement to fit a corresponding
groove in the rubber or other tyre.
This invention is applicable to cycles already in use.

COMPLETE SPECIFICATION.
A New or Improved Means of Securing the Tyres of Cycles without
the use of Cement.
I, JOHN PEARSON, of 8 Broom Avenue, Broom Lane, Levenshulme, near
Manchester, Engineer, do hereby declare the nature of my said 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 of securing the tyres of bicycles, tricycles,
safeties and other cycles to their rims without the use of cement and whereby
the same can be reversed when worn in order to afford a fresh wearing surface as
desired.
In performing my invention 1 employ a number of clips or fastenings similar
in cross section to the rim of the machine but having their longitudinal edges
turned inwards so as to afford a firm grip upon the rubber or other tyre to be
secured.
In order that my invention may be readily understood I have hereunto annexed
a sheet of drawings in which
Fig. 1 is an edge view and Fig. 2 a plan view of my improved clip or fastening,
Fig. 3 illustrates a portion of the rim and cushion tyre of a bicycle with my improved
clips shewn applied thereto. Fig. 4 is a transverse section of my improved clips
shewn applied to a solid tyre.

page_text: In all the views a. a. are my improved clips or fastenings composed of thin sheet
metal with their longitudinal edges turned inwards as aforesaid and arranged
to lie within the channel or groove of the rim at suitable distances apart along the
circumference of the wheel. These improved clips are by preference secured to
the cycle by means of small bolts and nuts b. b. screwing through holes formed in
the rim or the same may be secured by the spokes of the wheel provided with rivet
heads as illustrated in Figs. 7 and 8 which on being screwed home in the boss of the
wheel serve to secure the clips in position as well as the rim.
By making these improved clips or fastenings of a section slightly broader
than that of the rim to which they are to be applied as illustrated in Fig. 5 the
same are caused to close and grip the rubber or other tyre on being drawn or
screwed home to their seats as illustrated in Figs. 6 and 8 and thus secure the tyre
to its rim.
Fig. 9 illustrates an edge view and Fig. 10 a plan view of a modified form of
my improved clip the same being formed in halves with an elongated slot e to allow
the two halves to retire into the channel of the rim in case either of them should
come in contact with the ground.
Instead of simply turning the longitudinal edges of these clips or fastenings
inwards as illustrated the same can be formed with a swell or enlargement to fit
into a groove formed in the tyre.
These improved clips may be applied to cycles already in use.
My invention thus affords facilities for reversing the tyre so as to obtain
a fresh wearing surface by simply unscrewing or removing the clips and entirely
avoids the use of cement hitherto used for securing tyres to their wheels as
aforesaid.
Having thus 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,
1st. For securing the tyres of cycles to their rims the use and employment of
metal clips or fastenings preferably of the form and section herein before described
and illustrated on the accompanying drawing and mounted and operating in the
manner set forth.
2nd. The modified form of my improved clip or fastening shewn in Figs. 8 and 9
on the accompanying drawing and operating in the manner set forth.
Dated this 13th day of February 1892.
