Improvements in the Construction of Rims for Wheels of Bicycles,
Tricycles, and other Carriages.
I JAMES HUDSON of Selly Oak in the County of Worcester Tube Manufacturer
do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to hollow rims which are constructed either from a strip or
tube of steel or other suitable material and such rims may be made either with a
thickening or swelling on their underside through which the spokes take or of one
thickness.
It is often found that when a bicycle is rounding a corner that the wheel will slip in
a lateral direction.
My improved rim is constructed to prevent this and is made to receive three
separate rubber tyres thereon and these may be either round, half round or any other
convenient section.
When the rims are to be fitted with round tyres they are drawn with three indenta-
tions the one in the centre projecting and those on each side rather lower, so that
when the wheel cants over in turning a corner a second rubber comes in contact with
the ground and thus the possibility of slipping as before mentioned is prevented.
It will be understood that my improved rim can be drawn the necessary shape to
receive any desired section of rubber tyre.

COMPLETE SPECIFICATION.
Improvements in the Construction of Rims for Wheels of Bicycles,
Tricycles, and other Carriages..
I JAMES HUDSON of Selly Oak in the County of Worcester Tube Manufacturer
do hereby declare the nature of this invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement:-
This invention relates to hollow rims which are constructed either from a strip or
tube of steel or other suitable material and such rims may be made either with a
thickening or swelling on their under side through which the spokes take or of
one thickness.
It is often found that when a bicycle is rounding a corner that the wheel will slip in
a lateral direction.
My improved rim is constructed to prevent this and is made to receive three
separate rubber tyres thereon and these may be either round half round or any other
convenient section.
When the rims are to be fitted with round tyres they are drawn with three
indentations the one in the centre projecting and those on each side rather lower
so that when the wheel cants over in turning a corner a second rubber comes
in contact with the ground and thus the possibility of slipping as before mentioned
is prevented.
It will be understood that my improved rim can be drawn the necessary shape to
receive any desired section of rubber tyre..

That my invention may be better understood I have annexed drawings thereof
which I now proceed to describe.
Similar letters of reference denote the same parts in each figure in which they
occur.

page_text: Fig. 1. is a section of a rim made to receive three round tyres as shown by
dotted circles.
Fig. 2. is a section of a rim made to receive three round tyres and with a swelling
or thickening to receive spokes.
Fig. 3 is a section of a rim made to receive three round tyres and with a ridge on
to be drilled for attaching spokes.
Fig. 4. is a section of a rim made to suit three half round tyres as shown
by dotted lines.
Fig. 5 is a section of a rim made to suit three half round tyres with swelling
to receive spokes.
Fig. 6 is a section of a rim made to suit three half round tyres and with a ridge on
to be drilled for attaching spokes.
Fig. 7 is a section of a rim made to receive a tyre made to suit the shape of the
rim as shown by dotted lines.
Fig. 8. is a section of a rim made to receive a tyre inade to suit the shape of the rim
with a swelling to receive spokes.
Fig. 9 is a section of a rim made to receive a tyre made to suit the shape of the rim
and with a ridge on to be drilled for attaching spokes.
In the drawing "A" is the rim in every figure. In figures 2. 5 and-8-"a" is a
swelling or thickening of the metal at that part through which the spokes are fitted
and-in figures 3. 6.and.9"a" is the ridge for attaching spokes. In figures 1, 2, 3, 4, 5
and 6 "666" are the tyres and in figures 7, 8 and 9 cc care the tyres-which-in
this modification are formed in one piece.
Having now particularly described and ascertained, the nature of iny said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The construction of rins for wheels of those classes of carriages described in
the title substantially as herein before described and illustrated in the accompanying
drawings.
