PROVISIONAL SPECIFICATION.
Improvements in Attaching Pneumatic Tyres to the Rims
of Wheels.
I, HUBERT PRICE, of No. 36, George Road, Edgbaston, in the County of
Warwick, India-rubber Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to that class of pneumatic tyres which are attached to
the rims of wheels by wires passing through pockets or sleeves in the edges of
the cover.
According to my invention I bend the ends of each wire (projecting from the
pocket) at right angles and pass the said ends through a hole or holes in the
sides of the rim, that is to say, parallel to the axis; by which arrangement when
the tyre is inflated the ends of the wires being drawn together will be locked in
position without the necessity of employing screw-nuts. The openings in the
pockets through which the ends of the wires pass are of sufficient length to allow
of the wires opening for removing the tyre when deflated.
By this arrangement a pneumatic tyre can be put on and removed from a
wheel with great facility.
Instead of bending the ends of the wires as above stated I may attach separate
pieces to the ends of the wires to pass through the holes in the side of the rims.

COMPLETE SPECIFICATION.
Improvements in Attaching Pneumatic Tyres to the Rims
of Wheels.
I, HUBERT PRICE, of No. 36, George Road, Edgbaston, in the County of
Warwick, India-rubber 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 :-
My invention relates to that class of pneumatic tyres which are attached to
the rims of wheels by wires passing through pockets or sleeves in the edges of
the cover.
According to my invention I bend the ends of each wire (projecting from the
pocket) at right angles and pass the said ends through a hole or holes in the sides
of the rim, that is to say, parallel to the axis; by which arrangement, when the
tyre is inflated, the ends of the wires being drawn together will be locked in
position without the necessity of employing screw-nuts. The openings in the
pockets through which the ends of the wires pass are of sufficient length to allow
of the wires opening for removing the tyre when deflated.
By this arrangement a pneumatic tyre cau be put on and removed from a wheel
with great facility.
Instead of bending the ends of the wires as above stated I may attach separate
pieces to the ends of the wires to pass through the holes in the sides of the rim.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :—

page_text: Figure 1 is a side elevation of a portion of a wheel rim and pneumatic tyre
having my improvements applied thereto; and,
Figure 2 is a similar view to Figure 1 but having part of the wheel rim cut
away to shew the attaching wires:
Figure 3 is a section on the line 3-3, Figure 1; and,
Figure 4 is a sectional plan :
Figure 5 is a view similar to Figure 4 illustrating a modification of my invention;
and,
Figures 6 and 7 are respectively a plan and side view of a detail of the same.
Similar letters of reference indicate corresponding parts in the several figures.
a is the wheel-rim, b the tyre jacket or cover, and c, c the securing wires, the
said wires having their ends bent as shewn most clearly at c¹ in Figures 3 and 4,
the adjacent bent ends of each wire being passed through a hole d in the rim.
With this arrangement the diameter of the wire rings c, c when their ends are
placed together must be less than the diameter of the edges of the rim.
In order to remove the tyre it is only necessary to push the bent ends back out
of the holes d, d.
Instead of bending the ends of the wire as shewn in Figures 1 to 4, I sometimes
screw onto the ends of the same nuts e, e, as shewn in Figures 5, 6 and 7, each of
which nuts has projecting from it laterally a pin c¹ semi-circular in transverse
section, which semi-circular pins when placed together serve the same purpose as
the bent ends of the wire hereinbefore referred to. If desired the said pins c', c'
may be screw-threaded externally and provided with nuts f, f.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what 1
claim is :-
-
1. The improvements in attaching pneumatic tyres to the rims of wheels con-
sisting in bending the ends of the attaching wires and passing such bent ends
through holes in the rim, substantially as described with reference to Figures
to 4 of the accompanying drawing.
2. The modification of my invention wherein nuts, having semi-circular pins
formed upon them are employed substantially as described with reference to
Figures 5, 6 and 7 of the accompanying drawing.
Dated this 24th day of October 1894.
