PROVISIONAL SPECIFICATION.
Improvements in Rims and Tyres of Wheels for Cycles and other
Vehicles.
I, James George Galley, of 181 Neville Road, Upton Park, London, E.
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention consists in an improvement in the design and shape of rims and
tyres for cycle and other wheels.
The tyre is composed of rubber insertion, or other suitable material, in two or
more layers, the inner section to be a tube fitted with a suitable connection to attach
to a hand pump for inflating same.
"
The outer cover or coverings to protect the inner tube above named I form
with tubes on their edges, the whole being made of some suitable material, the
tubes on these coverings being furnished with a connection for inflation similar to
the inner tube mentioned above, such inflation being made after the said tubes are
placed inside tube shaped recesses formed on each side of the metal rim
upon which
they are to be fitted. These tube shaped recesses have an opening running round
their upper side, sufficiently wide to admit of the tubes on the edges of the outer
cover or coverings being placed in the said recesses before they are inflated. Or I
can make the metal rims with the tube shaped recesses formed with the openings
underneath, so as to permit of the outer cover or coverings passing round the
outside of the metal rim, and the tubes on the edges being then fitted into the
openings.
After the tubes are placed in position in the tube shaped recesses, I inflate
same by means of a pump in the usual way, and the cover or coverings are then
held elastically and will not come out.
By means of this invention I have a very ready means of securing the tyres to
the rims, at the same time obtaining a high degree of elasticity, & also a ready
means of detaching the tyres by exhausting same.

COMPLETE SPECIFICATION.
Improvements in Rims and Tyres of Wheels for Cycles and other
Vehicles.
I JAMES GEORGe Galley, of 181 Neville Road, Upton Park, London, E.,
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 :-
My invention consists in an improvement in the design and shape of rims and
tyres for cycle and other wheels.
The tyre is composed of rubber insertion, or other suitable material, in one, two,
or more layers, the inner section to be a tube fitted with a suitable connection to
attach to a hand pump for inflating same.
.
The outer cover or coverings, to protect the inner tube above named, I form
with tubes on their edges, the whole being made of some suitable material, the tubes
on these coverings being furnished with a connection for inflation similar to the
inner tube mentioned above, such inflation being made after the said tubes are
placed inside tube shaped recesses formed on each side of the metal rim upon
Paine 871

page_text: which they are fitted. These tube shaped recesses have an opening running round
their upper side, sufficiently wide to admit of the tubes on the edges of the outer
cover or coverings being placed in the said recesses before they are inflated. Or I
can make the metal rims with the tube shaped recesses formed with the openings
underneath, so as to permit of the outer cover or coverings passing round the
outside of the metal rim and the tubes on the edges being then fitted into the
openings.
After the tubes are placed in position, in the tube shaped recesses I inflate
same by means of a pump in the usual way and the cover or coverings are then
held elastically and will not come out. By means of this invention I have a very
ready means of securing the tyres to the rims, at the same time securing a high
degree of elasticity, and also a ready means of detaching the tyres by exhausting
"same.
For the purpose of inflation I can use either air, water, or any suitable fluid; or
in the case of the small tubes on the edges of the outer covering, I can inflate or
expand same also, by means of a core of solid rubber, or a core made of any suitable
material, large enough to prevent the said tubes being drawn or forced from their
position in the tube shaped recesses or channels in the metal rim, until such core is
withdrawn; the core, as in the case of the water, air, or fluid, being inserted after
the side tubes are inserted in the recesses.
The outer band or cover made of rubber, canvas, insertion, or any suitable
material, as already stated, and the side tubes may be formed together or may be
made separately, and connected together by means of solution or in any suitable
manner.
When solid rims are used there will be a space between the lower or inner side
of the large tube, and the rim, this space I propose filling with cork dust cement,
cocoa nut fibre, or any other suitable light material.
The outer covering or band with the side tubes may be used without the inner
tube, in which case it would be necessary to make the rim (which will have been
pierced to admit the spokes) air tight. This can be done by means of a thin strip
of rubber, or other suitable material, of proper width, fastened on to the rim by
means of solution.
My improved tyres & rims obviate the present necessity of fastening by means
of the application of adhesive cement, lacings, lugs and bolts, clips, wires, &c., and
give not only a simple and ready means of fastening the tyre to the rim, but also
It should be stated, that
an equally simple and ready means of detaching same.
both the inner tube, and the tubes on the edge of the outer protecting case or cover,
are fitted with a back pressure valve, of any suitable construction, in the usual
manner, so as to prevent the escape of the air or fluid after inflation.
In the drawings annexed hereto the methods and various forms of construction
are given
--
Fig. 1. shows a section through a tyre and rim, A. being the inner tube of rubber
or other suitable material, with an orifice B. for inflating or expanding same. C. is
the outer protecting cover, made of any suitable material, having small tubes D. D.
running round the outer edges, fitted with a hole for expanding or inflating them
shown E. E. These small tubes are inflated or expanded after they are placed
inside the two open tubes or channels F. F. running round the metal rim, the
opening to receive the tubes before inflation or expansion being on each side as
at FF. The space G. can be filled up with cork dust cement, cocoa nut fibre,
or any suitable light material.
Fig. 2. shows a section similar to Fig. 1 but without the inner tube A., a strip
of suitable material being fixed round the metal rim at H. to make the rim air tight
where pierced for the insertion of the spokes, and an opening being made for
inflation or expansion of the cover C. as in the case of the inner tube, the cover
being held as in Fig. 1 by means of the small tubes D. D. inserted in the open
tubes or channels on the rim F. F.
