Improvements in Pneumatic Tyres for the Wheels of Cycles and
other Vehicles.
We, BERNARD MITCHELL, of 58, Boar Lane, Leeds, in the County of York,
Pianoforte Dealer, and NORRIS RHODES HEPWORTH, of Torridon, near Headingley,
Leeds, County of York, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to so attach the outer covers to the tyres as to
allow for expansion and contraction.
We employ two flat metal bands inserted in the edge of the outer cover for
securing the same upon the rim.
The flat bands are not joined together at their ends but are left unattached
and overlap, one end of the band being made hollow or in slot form so that the
other end may be received or slide therein so as to allow for expansion and con-
traction without coming into contact with any part of the outer cover.

Improvements in Pneumatic Tyres for the Wheels of Cycles and
other Vehicles,
We, BERNARD MITCHELL, of 58, Boar Lane, Leeds, Pianoforte Dealer, and
NORRIS RHODES HEPWORTHI, of Torridon, near Headingley, Leeds, in the County
of York, 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 pneumatic tyres for the wheels of cycles and other
vehicles, and has for its object to construct an improved form of band for retain-
ing the tyres on the rims."
According to this invention we insert in each edge of the tyre cover a flat
metal band, the ends of which overlap. One end is slotted while the other end
carries a stud adapted to engage with this slot and slide therein.
The accompanying drawing illustrates on an enlarged scale the overlapping
ends of our improved band when disengaged from each other.
The band is formed of a flat strip of metal A preferably with the edges turned
over as at A¹ to form a beading. In one end of the band is cut a slot B, the

page_text: end of which adjacent to the extremity of the band is enlarged as at B1 to
allow of the passage of a stud C carried on the other end of the band. The stud
is provided with a flat head of a size which will just pass through the opening B¹,
and with a neck C¹ of sufficient size to allow it to slide freely in the slot B. The
length of the neck is also sufficient to allow of the stud sliding freely in the
slot but not enough to allow of much play between the head of the stud and
the band.
When applying the band to the edge of the cover of a pneumatic tyre it is
passed into a pocket in the edge of the cover, and when in position the stud C
is passed through the opening B. and thence. moved into the .slot B.
The head C of the stud is preferably bevelled as at C to facilitate passing the
stud through the opening B¹.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
A retaining band for a pneumatic tyre having a slot such as. B B at one, end
and a stud such as C C C at the other end, and with or without beaded. edges,
substantially as and for the purpose described and illustrated in the accompany-
ing drawing.
