A New or Improved Means for Attaching Pneumatic Tyres and the
like to the Rims of Cycle and other Vehicle Wheels.
I WILLIAM HENRY DALLIMORE of 92 Abbeville Road Clapham Common
London, S. W. Gentleman, do hereby declare the nature of my said invention to be
as follows:-
The object of my invention is to construct a new or improved means for attaching
pneumatic and analogous tyres to the rims of cycle and other vehicle wheels,
whereby the outer covers or jackets of such tyres are rendered more easily
detachable than those at present in use.
According to my invention I attach the jacket to the rim by a number of
fasteners formed of metal wire or stamped out of sheet metal or cast to shape.
The fasteners may be in the form of a T the horizontal bar being formed with a
projection or pin or hook at each end, the lower end of the vertical bar being
provided with means for securing the fastener to the rim such, for instance, as a hole
to receive the end of the spoke and secured thereto by a nut.
The outer cover or jacket is provided with holes or perforations with which the
pins or hooks engage, and the fasteners being forced down upon the inner surface
of the rim by the pressure of air in the inner or inflatable tube, secure the cover
firmly on the rim.
The fasteners may be made from suitable lengths of wire soldered or otherwise
attached to strips of metal secured to the rim, the essence of the invention being
securing the jacket to the rim without the aid of a continuous wire or its equivalent
in its edges.

A New or Improved Means for Attaching Pneumatic Tyres and the
like to the Rims of Cycle and other Vehicle Wheels.
I WILLIAM HENRY DALLIMORE of 92 Abbeville Road, Clapham Common,
London, S. W. Gentleman, 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:-
The object of my invention is to construct a new or improved means for
attaching pneumatic and analogous tyres to the rims of cycle and other vehicle
wheels, whereby the outer covers or jackets of such tyres are rendered more easily
detachable than those at present in use.
According to my invention, I attach the jacket to the rim by a number of
fasteners formed of metal wire or stamped out of sheet metal or cast to shape.
The fasteners may be in the form of a T the horizontal bar being formed with a
projection or pin or hook at each end, the lower end of the vertical bar being

hole to receive the end of the spoke and secured thereto by a nut.
The outer cover or jacket is provided with holes or perforations with which the
pins or hooks engage, and the fasteners, being forced down upon the inner surface
of the rim by the pressure of air in the inner or inflatable tube, secure the cover
firmly on the rim.
The fasteners may be made from suitable lengths of wire soldered or otherwise
Attached to strips. of metal secured to the rim, the essence of the invention being
securing the jacket to the rim without the aid of a continuous wire or its equivalent
in its edges.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a section on the line of Fig. 2, and Fig. 2 is a plan of a portion of a
rim, of a cycle or other wheel showing one method of fitting the fasteners,
according to my invention, by means of short pieces of wire attached to the rim.
Fig. 3 is also a plan of a portion of a rim showing another method of fitting the
fasteners.
Fig. 4 illustrates another form of fastener.
Fig. 5 shows a portion of the outer cover or jacket fitted with wire to form eyelets,
and Fig. 6 is a perspective view of a fastener for use with Fig. 5.
The outer cover is made as usual of rubber a and canvas b. Near the outer
edges of the cover a number of holes or perforations c are made, forming eyelets for
the passage of the fasteners d and d¹. The fasteners may be formed and secured
to the rim g as shown in Fig. 2, in which short pieces of wire are bent at each
end in the form of a hook d, an intermediate hook d' being made fast to the wire
between two sockets e e as shown in Fig. 2. The intermediate hook d' is provided
with a plate, which receives the pressure of the pneumatic tube, when inflated, and
thereby holds the bent ends of the hooks d and a' in the eyelet holes c of the
cover.
A strip of canvas, rubber or other material 6' is placed over the fasteners and
the inflatable tube f is passed round the rim in the usual manner, and the cover is
then attached to the hooks. When the tube is inflated, it presses the hooks tightly
against the rim, and thereby secures the cover in position, the cover being capable
of removal ouly when the inner tube is in a state of collapse.
Referring to Fig. 3 a number of hooks d', attached to flat plates, are shown.
These plates are pivoted at to wires, which may be soldered to the rim, or
riveted, or otherwise attached thereto, and turned to the right and left, so as
to engage the eyelets of the cover and thereby secure the same, when the inner tube
is inflated.
Fig. 4 illustrates another form of fastening, consisting of a series of plates k
pivoted to the rim by wires at h, and having a number of hooks d. d. which engage
in eyelet holes in the edges of the cover the plates k being held down to their work
by the pressure of the iuner inflated tube.
The edges of the cover are stiffened with wire, cord or other material between
the folds; firm but slightly extensible edges being thereby formed, capable of
resisting the strain on the eyelets when the tube and cover are extended; in some
cases I utilise short lengths of wire m the ends of which are formed as eyelets, as
shown at c' in Fig. 5; double ended hooks n, as shown in Fig. 6, may be used to
secure the cover the hooks passing through the eyelets and cover in the manner
above described and shown in Fig. 1.
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 :-
1. The new or improved means for attaching pneumatic tyres and the like to the
rime of cycle and other vehicle wheels substantially as described..

page_text: 2. In combination with pneumatic tyres, and the like the application and use of"
hooks d and d pivoted to the rim and arranged so as to be held in position by
means of plates integral with the hooks d¹, substantially as herein before described
and illustrated by Figs. 1, 2 and 3 of the drawings.
3. In combination with pneumatic tyres and the like, the application and use of
plates k, pivoted to the rim and provided with hooks integral therewith, substantially
as herein before described and illustrated by Fig. 4 of the drawings.
4. In combination with pneumatic tyres and the like, the application and use of
wires, cords, or the like m attached to the edges of the cover b, the wires or the like
being utilised at suitable intervals in the formation of eyelets c¹ for the reception.
of the hooks n, substantially as herein before described and illustrated by the
drawings.
