COMPLETE SPECIFICATION.
Improvements in and connected with Pneumatic Tyres for Velocipede
or the like Wheels.
I, GEORGE WILLIAM LOMAS, of 27, Crummuck Street, Hightown, Manchester, in
the County of Lancaster, Engineer, 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 improvements in that class of pneumatic tyres for
velocipede and the like wheels wherein the covering is edged with wire for the
attachment of the tyre to the rim of the wheel and detachment thereof.
This invention has for its object to so form and provide the said wires with means
that the tyre is secured more firmly to the rim and prevented from creeping thereon
and the attachment and detachment of the same is greatly facilitated.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view, Fig. 2 an end view of Fig. 1 showing the link, coupling or
fastener adapted to engage the wire ends, Fig. 3 a side view and Fig. 4 a sectional
end view of Fig. 3 showing the link, coupling or fastener turned and the wire ends
locked in position. Figs. 5, 6 and 7 are side view, plan and end view respectively
of the link, coupling or fastener only. Fig. 8 is a side view of one end of the wire.
Fig. 9 is a side view showing a portion of the tyre and rim of a wheel and Fig. 10
a cross section thereof with our invention applied.
In carrying out my invention and referring to the figures generally, I form each
end of the wires a with a head a¹ which are adapted to be engaged and drawn
together by a link or coupling b, Figs. 1 & 2, in such a manner, that on turning
the same the wire ends become locked by the link or coupling b, as shown
in Figs. 3 & 4.
The link or coupling 6 I form with one or two cavities 61, in the present instance
one, which communicates with grooves 62 and near each end with a shoulder or neck 63
against which the heads a² of the wire ends are lodged.
The grooves 62 facilitate the placing of the wire heads against the shoulders or
necks 63 and the cavity b¹ serves to hold the wire ends behind. their heads rigidly in
position.
As a further precaution against creeping in large wheels the link or coupling b
may be placed into a pocket c formed in the rim, as shown in Figs. 9 & 10, or
between projections formed on the rim of the wheel as will be readily understood.
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 I
claim, is
1st. In pneumatic tyres of the type hereinbefore referred to, the combination of
a wire having heads a' with a link or coupling b adapted to engage and lock the
said wire ends rigidly in position, all substantially as and for the purpose set
forth.

page_text: 2nd. The link or coupling b, specified in the preceding claim, in combination
with a pocket c or means for holding the said link or coupling and thus the tyre
in position upon the rim of the wheel, all substantially as set forth.
