COMPLETE SPECIFICATION.
Improvements in and connected with Pneumatic Tyres for
Velocipedes and other Vehicles.
I, VERNON DE HORSEY DOWLER, of No. 515 Barking Road, Plaistow, in the
County of Essex, Mariner, 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 :-
My invention relates to certain improvements in and connected with pneumatic
tyres more especially of the kind described in the Specification of my Patent
No. 8256 of 1896 and has for its object to prevent creeping of the tyre and its
lateral displacement. I will describe any invention with reference to the accom-
panying drawings Figure 1 of which is a sectional perspective view of a portion of
a tyre constructed according to my invention. Figures 2 and 3 are respectively a
transverse section and a horizontal section of a portion of a tyre with the pueumatic
tube removed to shew more clearly means according to my invention for securing
the tyre to the rim or felloe of the wheel and Figures 4 and 5 are similar views
shewing my improved means for connecting together the edges of the outer covering
of the tyre. A represents the rim or felloe of the wheel, B the pneumatic tube
and C the outer cover. The cover 'C, is made of vulcanized rubber lined with
canvas D, or the like and is provided on the exterior with annular ribs or flanges E,
by which the tyre is held in position on the rim or felloe A by engaging in
recesses e forined in the edges of the said rim or felloe. Interposed between the
cover C, and the pneumatic tube B, is a. layer of cork F, of crescent shape in
transverse section as described in the Specification of my said Patent No. 8256
of 1896 the inner face of which may be covered with canvas or like material to
prevent the disintegration of the said cork. To prevent the tyre from creeping
1 connect the cover C, to the rim cr felloe A by means of rivets tags or like
fastenings a passed through the said cover (preferably from the interior) and
through openings in the rim or felloe the ends of the rivets or the like which project
outside the rim being turned down on to the rim or otherwise secured to prevent
the said fastenings from being displaced. In place of or in combination with the
ribe or flanges E on the cover I may form a rib E2 on the said cover as shewn in
Figure 4 and provide in the rim or felloe A a recess 6 to receive the said rib so as
to prevent the tyre from lateral displacement. The said rib E may be formed by
moulding or otherwise forming on the edges of the cover C, dovetail projections as
shewn at 2 in Figure 5 which serve to connect together the edges of the said cover
by interlocking the projections on one edge with the projections on the other edge
the said projections when thus interlocked securely connecting the said edges and
forming a continuous rib or projection round the cover to engage in the recess 6 in
the rim or felloe.
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. Pneumatic tyres for the wheels of velocipedes aud other vehicles constructed
substantially as hereinbefore described and illustrated by the accompanying
drawings.
2. A pneumatic tubular tyre for the wheels of velocipedes and other vehicles
having annular ribs or projectious on its sides to engage in recesses formed in the

page_text: rim or felloe of the wheel to prevent the lateral displacement of the tyre.
substantially as herein before described.
3. Connecting pneumatic tyres to the rims or felloes of the wheels of velocipedes
or other vehicles by means of tags rivets or like fastenings substantially as and for
the purpose herein before described.
4. Pneumatic tyres having a rib or projection as at E2, Figure 4, substantially as
and for the purpose hereinbefore described.
5. In or for pneumatic tyres an outer cover having on the edges dovetail projec-
tions by which the said edges are connected together the said projections when so
connected forming a continuous rib or projection to engage in a recess in the rim or
felloe of the wheel substantially as hereinbefore described.
Dated this 28th day of May 1896.
