Improvements in or relating to Pneumatic Tyres.
We, MORLAND MICHOLL DESSAU, Manufacturer, of The Ferns, Devonshire Street,
Tooting, in the County of Surrey, and THE WAPSHARE TUBE COMPANY, LIMITED,
of 3, Cross Lane, in the City of London, 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, and has for its object the construc-
tion of an improved form of wire fastening for tyres such as described in prior
Letters Patent No. 19502 of 1897 granted to Morland Micholl Dessau.
In the accompanying drawings
Figure 1 shows in part section the end of a wire fastening constructed accord-
ing to this invention, and
Figure 2 shows the method of securing the wire to the outer cover of the tyre.
On the wire A, to each end of which it is desired to secure a tag or tape B,
is mounted a sleeve C, preferably of metal, provided on its outer circumference
with a screw thread. One of these sleeves C is mounted at each end of the
wire, and whilst free to revolve upon the same is prevented from being drawn
off the end by a stud or bead D, which is itself kept in place by the rivetted
end A of the wire. When attaching the tag B the sleeve C is brought close
up to the bead D) when the tag is folded over the sleeve in such a manner that
part of it extends free beyond the end of the wire, whilst that end folded over
the sleeve extends beyond the sleeve on to the wire A. The tag may be secured
in any convenient manner in this position, but is, however, preferably sewn, as
indicated at B, so that it is made to bed itself into the thread on the outer cir-
cumference of the sleeve C, and thus become rigidly attached to the same. That
part which extends beyond the sleeve and on to the wire A is preferably sewn.
tightly upon the same, so as to prevent any movement of the sleeve and tag
in a direction away from the end of the wire. The folded parts of the tag may
then be cemented together in the usual well-known manner. Each end of the
wire is thus provided with a tag and is secured to the outer cover of the tyre
by cementing the tags to the cover, the ends of the wire overlapping as shown
in Figure 2.
It is obvious that a wire constructed in this manner will operate similarly to
those described in the Specification of Letters Patent referred to above.
Each edge of the cover may be provided with a wire constructed according
to this invention, and as it is necessary that each wire shall be free to slide
in its pocket, it is preferably covered with some loosely woven material E so
that the cover does not adhere to it during or after manufacture. Also to keep
the ends of the wire in place they may be passed through a loop of the same or
similar material at that point where they overlap.
It will be understood that the sleeve C may be variously modified, for instance
its outer surface may be plain instead of being screw-threaded, or it may be
ribbed, or may be formed of a spiral of wire, the convolutions being soldered or
otherwise connected together, so that a threaded surface is presented in which
LD

page_text: the sewing thread may embed itself. Also it may obviously be held in place by
the rivetted end A' of the wire only, although it is preferred to use the bead D
in conjunction with the rivet, and the bead may be soldered, screwed or otherwise
secured to the wire.
Again the sleeve may project beyond the end of the wire being secured to it
by a swivel joint in any well known manner, or a short length of wire may be
swivelled to the wire A as a substitute for the sleeve as will be easily understood.
Having now particularly described and ascertained the nature of the said
invention, and in what nianner the same is to be performed, we declare that what
we claim is :-
1. In a wire for fastening a tyre to a wheel-rim the combination with a tag B
of a screw-threaded or ribbed sleeve C mounted free on the end of the wire
substantially as and for the purpose described.
2. In a wire for fastening a tyre to a wheel-rim the combination with the
sleeve C of a bead or other retaining device D and a tag B secured to the sleeve
extending beyond the same on to the wire A at that end remote from the bead D
substantially as and for the purpose described.
3. In a wire for fastening a tyre to a wheel-rim the combination with the wire
of a sleeve C substantially as and for the purpose described.
4. In a wire for fastening a tyre to a wheel-rim the combination with the
wire of a sleeve or its equivalent connected to the end of the wire A by a swivel
joint substantially as and for the purpose described.
5. The complete wire fastening device for securing a tyre to a wheel rim sub-
stantially as described or illustrated in the accompanying drawings.
