Complete Specification Left, 17th Mar., 1897--Accepted, 17th Apr., 1897
We, EMILE GERARD and ADRIEN PICON, both of 21 Boulevard Poissonniere,
Paris, in the Republic of France, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object a construction whereby the tyre forming the
subject matter of the Patent, No. 15554 of 1894 can be applied to the wheels of
heavy vehicles of all kinds.
To this end the said tyre is surrounded by a sheath or outer cover composed of
linen-cloth or fabric and india rubber forming an integral part of the tyre and
contributing to its solidity.
The improved tyre comprises an inner cellular tube and an outer cover of india-
rubber provided with a laver of linen-cloth or fabric.
The outer cover may be moulded in one single piece around the inner tube so as
to completely enclose the same, or may be divided or slit in order to facilitate the
fixing. When once put in place the outer cover is secured around the tyre by a
suitable adhesive substance.
It must be well understood that we may modify the shape of the outer cover,
the number and the arrangement of the layers of fabric which it comprises (the
said fabric may if desired be omitted), the method of fixing the tyre to the rim of
the wheel, and so on.
