PROVISIONAL SPECIFICATION.
Improved Means of Fixing and Tightening the Tyres or Hoops of the
Wheels of Road and other Vehicles.
I, WILLIAM WORRALL of The Freemason's Arins Inn, Newbold Road,
Chesterfield, in the County of Derby, Wheelwright, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to provide an improved means of fixing and
tightening the tyres or hoops of the wheels of road and other vehicles and in
carrying the same into effect I form a casting consisting of two side plates and a
cross piece, the side plates being fixed one on each side of the felly and an opening.
being left in the said felly, in which is placed a device for expanding it so as to fix
or tighten the tyre or hoop thereon, the two ends of the felly at the opening are
formed of such a shape that they will effectually prevent the tightening device, to
be hereafter described, from falling out.
The device for expanding the felly and fixing or tightening the tyre or hoop
consists of a bolt carrying a block at its outer end of a dovetail or wedge section.
and engaging with the ends of the felly in the opening and projecting inwards, over
this bolt passes a loose block which as it is screwed up to the block on the end of
the said bolt by means of a nut on same, gradually widens the opening in the felly
and thus fixes or tightens the tyre or hoop on the outside.

It is evident however that I may employ any suitable device for expanding the
felly, to be placed in an opening formed therein and operated by any suitable.
means, and may also employ any suitable form of side plates and strengthening
cross plates, braces or the like therefor. The nut may also be a self-keying, or
lock-nut to minimise the risk of same becoming loose through vibration.
adopting this method nails or rivets will not be required in fixing the said tyres or
hoops and I may employ one or more of the said devices in fixing or tightening' the
tyre or hoop of a wheel.

COMPLETE SPECIFICATION.
Improved Means of Fixing and Tightening the Tyres or Hoops of the
Wheels of Road and other Vehicles.
I, WILLIAM WORRALL of The Freemason's Aims Inn, Newbold 'Road,
Chesterfield in the County of Derby, Wheelwright, 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 :-
The object of my invention is to provide an improved means of fixing and
tightening the tyres or hoops of the wheels of road and other vehicles and in order
that my said invention may be the more readily understood I have caused to be
annexed to this Specification a sheet of drawings the different figures and letters of
reference marked upon which will be hereinafter referred to.
The drawings illustrate the application of my invention to an ordinary heavy cart
wheel the spokes and other parts except the rim and felly being omitted as forming
no part of my invention.

page_text: Figure 1 is a section through the felly and tightening device on line a a. of
Figure 2 looking downwards.
Figure 2 is a vertical section of the same on line b. b. of Figure 1.
Figure 3 is a side elevation of the same.
In carrying out my said invention I form or cast a piece of metal consisting of
two side plates A, A' and a cross piece B, the side plates being fixed one on each
side of the felly C and an opening being left in the said felly in which is placed the
device for expanding it so as to fix or tighten the tyre or hoop J thereon, the two
ends C, C, of the felly at the opening are formed of such a shape that they will
effectually prevent the tightening device, to be hereafter described, from falling
out, the side plates A, A', being fixed to the felly at C on one side of the
opening by means of a rivet or screw D and a piece of metal E is fixed to the
felly at C on the other side of the opening by means of a dowel or other secure
method.
The device for expanding the felly and fixing or tightening the tyre or hoop
consists of a bolt F carrying a block G at its outer end of a dovetail or wedge
section and engaging with the ends of the felly or with the cross piece B and other
piece of metal E which are suitably shaped for the purpose; in the opening, and
projecting inwards, a loose block H is passed over the said bolt and as the said
block is screwed up by means of a nut I on same gradually widens the opening in
the felly and thus fixes or tightens the tyre or hoop on the outside.
It is evident however that I may employ any suitable device for expanding the
felly, to be placed in an opening formed therein and operated by any suitable
means, and may also employ any suitable form of side plates and strengthening
cross plates, braces or the like therefor and construct or form them of any suitable
metal or material and that my invention may be applied to either heavy or light
vehicles. The nut may also be a self-keying or lock nut to minimise the risk of
same becoming loose through vibration.
In adopting this method nails or rivets will not be required in fixing the said
tyres or hoops and I may employ one or more of the said devices in fixing or
tightening the tyre or hoop of a wheel.
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 :-
The improved device for fixing and tightening the tyres or hoops of the wheels
of road and other vehicles consisting of an expanding mechanism to be placed in an
opening in the felly, substantially as described and illustrated.
