An Improved Clip for Securing Elastic Wheel-tyres.
I, FREDERICK WILLIAM BENNETT of 48 Crampton Road Penge, Surrey, Provision
Dealer do hereby declare the nature of this invention to be as follows:-
The object of my invention is the production of a clip for securing elastic wheel
tyres.
In carrying my invention into effect I employ a clip of suitable form so as to
lie within the groove formed upon the felloe of the wheel. Said clip is further
provided with a spring, and toothed jaws, which expand to receive the elastic tyre,
said tyre being gripped by the toothed jaws before mentioned, and firmly retainėd
in position within the groove by the tension of the spring. A small bolt passes
through a hole in the bottom of the clip, and also through a corresponding hole
in the felloe. A long nut with suitable projections is also provided for the purpose
of connecting said bolt to one of the spokes of the wheel.

COMPLÈTE SPECIFICATION.
An Improved Clip for Securing Elastic Wheel-tyres.
FREDERICK WILLIAM BENNETT of 48 Crampton Road, Penge, in the County of
Surrey, Provision .Dealer 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 means for securing elastic wheel-tyres,
especially applicable for use upon velocipedes generally, and has for its object the
prevention of accidents to riders arising from the elastic tyre coming off when
in use.
*
In order that my invention and the manner of its application may be fully
understood I have appended the accompanying sheet of drawings, in which Fig. 1 is a
representation of part of a wheel fitted with my improved clip, Figs. 2 and 3 are
sectional views of a wheel so fitted, illustrating the manner of attaching my improved
clip, to be hereinafter fully explained. Figs. 4 and 5 are side elevations of said clip
shewing two methods of attachment, and Figs. 6 and 7 are plan views of same.
Similar letters of reference are used to indicate corresponding parts throughout the
drawings.
In carrying my invention into effect I employ a clip made of steel or other suitably
elastic metal and formed in the manner shewn by the side elevational views of same
Figs. 4 and 5 and the plan views thereof Figs. 6 and 7, each of which is provided
with teeth or serrations on its longitudinal edges so as to form a jaw to grip the
elastic tyre when in position upon the wheel, and the manner of application is as
follows. Within the groove of an ordinary velocipede or other like wheel A, I place,
at suitable distances apart from each other, as many of the clips B as may be required
according to the diameter of the wheel, each of said clips being provided with a hole
in the centre thereof, a small bolt C baving a stud, or head formed thereon passes
through said hole, and through a corresponding hole in the bottom of the aforesaid
groove, made to receive the same. The elasticity of the metal of which the clips B
are made and their cross sectional formation enables each one to expand to the full
extent of its flexibility so as to recieve the elastic tyre D which may now be sprung
around the periphery of the wheel A, so as to lie within the jaws of the clips B, and
D

page_text: by the tension of its elasticity to rest upon the heads of the bolts C, the position of
the tyre D, the clip B, and the wheel A relatively to each other are illustrated by the
sectional view Fig. 2. A suitable nut E is now screwed upon the bolt Cuntil the
clip B is firmly seated within the groove of the wheel A. This operation by reason
of the said groove being of lesser diameter than the clips B, compresses the clips so
that the jaws or serrated edges b become embedded in the sides of the elastic tyre Dand
firmly holds it in the position shown by Fig. 3, which may be read as a sectional view
of Fig. 1 upon the line A B. Or I may dispense with the bolt (and form a boss c
Fig. 7 upon the inner surface of the clip B surrounding the hole therein and provided
with an internal thread so that a screw è may be passed through the hole in the bottom
of the groove and so engage with the clip B as shewn at Figs. 5 and 7. Or I may
provide a long nut with suitable projections in place of the nut E, having an internal
right and left handed thread so as to engage with the bolt C and one of the spokes F
of the wheel, said spoke having a thread formed thereon for that purpose. Or I may
dispense with the bolt C and the screw e and form a bead upon each of the spokes F,
passing said spoke through the hole in the clip B and the corresponding hole in the
groove in the same manner as the bolt C, and force the clip within the groove by
attaching the spoke to the hub of the wheel in the usual manner. By the adoption of
either of the foregoing methods of attaching the clip B to the felloe A, the grip of the
jaws b upon the elastic tyre D is practically the same, rendering the removal of the
tyre D while so held absolutely impossible.
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.
In securing elastic tyres to wheels, the employment of a serrated spring clip B, in
combination with a bolt C or screw e or a spoke F substantially as and for the
purposes herein described with reference to the appended drawings.
