Improvements in and relating to Pneumatio Tyres.
I, THOMAS ROUSE, of The Mill House, Upminster, in the County of Essex,
Gentleman, do hereby declare the nature of this invention to be as follows
--
This invention relates to an improved construction of pneumatic tyre for the
wheels of carriages and other road vehicles, and it consists essentially of an arch-
shaped cover having a base formed on one of its edges with a flexible flange on the
free edge of the base, of a pocket formed in the base of the cover adapted to
receive a contractible band adaptod to fix the base of the tyre on to the felloe of
the wheel, and of two bands, one in the free edge of the cover and the other in the
edge of the flexible flange on the base of the cover, one or both of the said bands
being adjustable in length.
}
In one form the band in the free edge of the cover is made in the form of a hoop
or ring and it is of such a diameter that it just fits over the base of the cover, the
band in the edge of the flexible flange on the base being in this case made
contractible and expansible by means of a right and left-hand screw coupling or its
equivalent, so that it may be adjusted to prevent the outward movement of the
free edge of the cover on, the inflation of the air tube.
In another construction the band in the edge of the flexible flange on the base of
the tyre is made in the form of a hoop or ring and the band in the free edge of the
cover is made expansible and contractible by means of a screw coupling or its
equivalent, and as a further modification both of the said bands or wires may be
mado contractible and expansible.
The air tube is of the ordinary typo provided with any suitable valve for
inflation and deflation.
To stiffen the cover and prevent any tendency to roll or wear on the odge of the
fixing band, the corner at the junction of the cover with the base is preferably
filled up with an angle piece of rubber or other suitable material.
In addition to clamping the base of the cover on to the felloo of the wheel by
means of the band contained in the pocket radial bolts may also be used if
required.
As a modification the cover of the tyre may be entirely separate from the base
in which construction the base would have a flexible flange on each edge

I, THOMAS ROUBB, of The Mill House, Upminster, in the County of Essex,
Gentleman, 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 :-
This invention relates to an improved construction of pneumatic tyre for the
wheels of carriages and other road vehicles, and it consists essentially of an
arch-shaped cover having a base formed on one of its edges with a flexible flange
on the free edge of the base, of a pocket formed in the base of the cover adapted to
receive a contractible band adapted to fix the base of the tyre on to the felloe of
the wheel, and of two bands, one in the free edge of the cover and the other in the
edge of the flexible flange on the base of the cover, one or both of the said bands
being adjustable in length.
In the accompanying drawing which illustrates this invention :-
Figure 1 is a view in transverse section of one form my improved tyre may
assume.
Figures 2 and 3 are broken views in elevation and plan respectively of a suitable
tightening device for the fixing band, and
Figures 4 and 5 are diagramatic views showing alternative methods of opening
the tyre cover to expose the air tube.
Throughout the views similar parts are marked with like letters of reference.
The cover A of the tyre is made of rubber reinforced with canvas or other
fabric in the well-known manner and its shape in cross section approximates to
that of an arch with a flat base In the base a of the cover is formed a pocket a¹
in which is located a band B adapted to be drawn up to fix the cover A on to the
ordinary metal rim X of a wheel.
The band B is provided with any suitable device such as the one illustrated
by Figures and 3 for drawing it up, and it may also be provided with one or
more extra radial studs or bolts adapted to pass through the rim X and felloe X'
for preventing any possible side movement of the cover A on the wheel rim.
The fixing device illustrated consists of a bolt C' having a flat head c into which
is threaded a small set screw c'. The bolt passes through a holo in one end b of
the band B and is provided with a nut c whoreby it can be locked to the wheel
rim. In the other ond 6 of the band B is a slot 6 through which the bolt Cl
passes and on it is a projection against which the set screw c' impinges and thus
draws the band up taut.
The cover A is preferably mounted out of centre with the rim X as shown in tho
drawing so that the outside edge of the said rim stands proud of the side of the
pneumatic tyre whon inflated and thus protects it from being rubbed up against
curb stones and tho like.
The cover A is divided at one side and on one edge of the base a of the cover A
18 formed a flexible lip a in the edge a of which is formed a pocket adapted to
receivo a hoop or band C preferably made of steel wire. In the other
edge a of the cover A is formed a pocket adapted to receive a hoop or
band D preferably made of steel wire. One or other of the hands C and D
1s made adjustable in its length by means of a right and left handed screw
coupling or equivalent device to permit of the two edges of the cover being
interlocked. If the band C is made inextensible in the form of a hoop the
band D is made adjustable and its length is contracted when fixing tho cover until
it is firmly seated on the top of the base a of the covor as shown by Figure 1.
To expose the air tube E-which is of the well-known construction-the band D
is expanded until the edge at of the cover is of such a size that it will pass over the

page_text: edge a containing the hoop C as shown by Figure 4. On the other hand if the
band D is made extensible in the form of a hoop the band C is made adjustable,
so that its length can be contracted to reduce the circumference of the edge a to
allow the edge a' containing the hoop D to pass over it as shown by Figure 6.
To stiffen the cover and prevent any tendency to roll or wear on the edge of the
fixing band, the corner of the cover A when made in one with the base a is
preferably filled up with an angle piece a of rubber or other suitable material.
I prefer to locate the side of the tyre cover adapted to be opened on the inner side
of the wheel rim, but this is not obligatory.
My improved pneumatic tyre can be fixed to any existing road vehiclo wheel by
merely drilling two or more holes through the rim and felloe for the passage of the
stem of the inflation valve and for the bolt or bolts of the fixing band, it can also
be readily detached thus allowing the wheel to be run on the ordinary iron rim in
case the tyre becomes so damaged that it cannot be repaired on the spot
I am aware that pneumatic tyres have already been made with divided covera
the edges of which contain inextensible bands or cords adapted to interlock and
thus close the cover, and also that the covers of pneumatic tyres have been
fixed to wheel rims by adjustable bands, and I do not therefore claim such
broadly, but
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.) A pneumatic tyre for application to existing vehicle wheels consisting
essentially of an archi-shaped cover having a circumferential pocket in its one edge
and a flat hase attached to its other edge, of an expansible and contractible fixing
band located in a cucumferential pocket in the base of the cover, of a flexible
circumferential lip on the fiee edge of the baso of the cover having a circum-
ferential pocket in its edge, of two hoops or bands located in the pockets in tho
edges of the flexible lip and the cover respectively-one of the said hoops or bands
being made expansible and contractible, and of an air tube provided with a valve
for inflation and deflation, as set forth.
(2.) The combination with a wheel rim of a pneumatic tyre consisting essentially
of a cover A having a circumferential pocket at in one edge, and a base a attached
to the other edge and having a circumferential pocket and a flexible lip a³, of
an expansible and contractible fixing band B located in the pocket a' in the
base a of the tyre cover, of hoops or bands C and D located in the pockets in
the edges of the flexible up of the base and cover respectively-one of the said
hoops or bands being made expansible and contractible, of an angle piece a of
rubber or other suitable material located at the junction of the cover with the base,
and of an air tube E provided with a valve for inflation and deflation, as set
forth.
(3.) In a velucle wheel, the combination with the rim X and felloe X, of a
pneumatic tyre consisting essentially of a cover A, having a base a, of a fixing
band B, located in the base a of hoops or bands C and D located in pockets
in the edges of the cover A and base a respectively, and of an air tube E
the whole mounted on the rim of the wheel out of centre therewith, so that the
said rim stands proud of the side of the tyre when it is inflated, as and for
the purpose set forth.
