PROVISIONAL SPECIFICATION.
Pneumatic Tyre for Velocipedes and other Vehicles.
1, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings in the
County of London, Patent Agent, do hereby declare the nature of this invention,
(a communication to me from Eugène Jeannerot, of 43 Rue de Thizy, Villefranche,
in the Department of the Rhône, in the Republic of France, Manufacturer of
Pneumatic Tyres for Velocipedes) to be as follows:-
This tyre is applicable to the wheels of velocipedes and other vehicles, and is
composed of an ordinary inner or air tube and the outer cover, the fixing of which
to the felloe or rim of the wheel is obtained by improved arrangements.
The accompanying drawing shows, at Figure 1, the complete tyre fixed to the
felloe or rim.
Figure 2 is a cross section on the line 1. 2 of Figure 1.
The method of tightening the wires which serve for fixing the tyre on the rim
forms the essential feature of the invention.
The edges of the outer cover E being thickened are placed in the lateral grooves
or spaces of the rim J, in which they are held by two rings G. G. of steel or other
metal wire. These rings are each closed by a sleeve F into which the two ends of
the metallic wire are screwed with right and left handed screws so that it is only
necessary to turn the sleeve by means of a broach or pin introduced into the
holes ee to strongly contract the ring and firmly fix the edges of the outer
cover E.
The edge of the rim as also the thickened edges of the outer cover E are
notched the length of the sleeve, so as to enable the latter to turn readily.
In lieu of being on the exterior, the rings G G might as well be threaded
through sheaths or tubes made in the edges of the outer cover, the screwed ends
only being allowed to project therefrom to receive the sleeve.

Pneumatic Tyre for Velocipedes and other Vehicles.
1, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from Eugène Jeannerot, of 43 Rue de Thizy, Villefranche,
in the Department of the Rhôue, in the Republic of France, Manufacturer of
Pneumatic Tyres for Velocipedes) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This tyre is applicable to the wheels of velocipedes and other light carriages;
it is composed of an ordinary inner or air tube held in position by an outer cover,
the fixing of which to the felloe or rim of the wheel is obtained by improved
arrangements.

page_text: The accompanying drawings show, at Fig. 1, the complete tyre fixed to the felloe
or rim.
Fig. 2 is a cross section on the line 1. 2. of Fig. 1.
Fig. 3 represents a modification of the arrangement shown at Figs. 1 and 2.
The air tube D is covered with an envelope or outer cover E. whose edges dd,
which are thickened in the form of ribs, are placed in the lateral grooves or spaces
a a of the rim or felloe J; above these thickened edges or ribs are placed two
rings G G of steel or other metal wire; these rings are not soldered or brazed,
but are well jointed at their ends by means of a small sleeve F into which the two
ends of the ring are screwed by means of right and left hand threads, so that, the
ring having been opened out to pass it over the edges of the rim or felloe, it can
be strongly closed above the thickened edge or rib d, which it holds firmly at the
bottom of the cavity or recess a. This tightening is effected by means of a broach
or pin passed into the holes e e formed in the sleeve F. The edge of the rim or
felloe, as also the thickened edge or rib d of the outer cover, are notched or
recessed the length of the sleeve, so as to form a space where it can easily turn.
It will be understood that the shape of the ribs & forming the edges of the outer
cover E may be varied, as also that of the cavities or recesses a a of the rim or
felloe, provided the metallic ring can offer an effective opposition to the detachment
of the outer cover.
Fig. 3 shows an example of a very practicable and preferable arrangement in
which the metallic rings are enclosed in two spaces or tubes d d formed by the edges
of the envelope or outer cover E. These spaces or tubes are removed the length
of the sleeve F, which latter, having the same diameter, occupies the place of the
part removed without causing any projection and without necessitating any
notching of the felloe or rim.
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
-
1. A pneumatic tyre for wheels of velocipedes and other vehicles in which the
air tube is held by an outer cover whose edges are fixed to the rim or felloe by
two extensible rings tightened by means of sleeves provided with right and left
hand screw threads, these rings being capable of pressing upon thickened edges
formed on the outer cover, or of being enclosed within spaces or tubes made in
the edges of the said outer cover, substantially as herein shown and described.
2. The improved pneumatic tyre substantially as herein shown and described.
