PROVISIONAL SPECIFICATION.
Improvements in Wheel Rims for Velocipedes and other Light
Vehicles.
I, HENRY JELLEY, of 27 Malva Road, Wandsworth, in the County of Surrey,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-.
My invention relates to an improved construction of hollow rim for the wheels
of velocipedes and other light vehicles, and it has for its object facilitating the
coustruction of the said rims, increasing their strength and generally making them
more perfect.
My improved rim is constructed out of four pieces of sheet metal, one piece
forming the outer shell or inner part of the rim, another the inner shell or outer
part, and the others the binding strips for fixing the edges of the two other parts
together.
:
The outer shell is made of any desired shape to give the desired stiffness to the
rim and of the required thickness to give a proper and sufficient support for the
ends of the spokes. The inner shell is made of the desired shape according to.
the type of tyre it is intended to carry. The free edges of the outer shell are
bent outwards to form small flanges in the horizontal plane and the free edges of
the inner shell are bent inwards to form similar flanges. Over each pair of flanges
on each side of the rim are placed narrow strips of metal the edges of which are
bent under the said flanges to hold the two parts of the rim together. The thick
flanges thus formed are then turned downwards on the inside and outside of the rim
respectively to complete the rim forming well rounded and thickened edges on each
side thereof.
By this construction the inner shell or outer part of the rim may be made of a
dead size which is essential for many types of pneumatic tyres.

COMPLETE SPECIFICATION.
Improvements in Wheel Rims for Velocipedes and other Light
Vehicles.
.
I, HENRY JELLEY, of 27 Malva Road, Wandsworth, in the County of Surrey,
Cycle Manufacturer, 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 an improved construction of hollow rim for the wheels
of velocipedes and other light vehicles and it consists in forming the rim out of
four strips of metal, one forming the outer shell of the rim, another the inner shell
thereof, and the two others the binding strips for fixing and securing the edges of
the other two parts of the rim together, the object being to facilitate the con-
struction of the said rims, increasing their strength, and generally making them
more perfect.

page_text: I attain this end in the manner shown by the accompanying drawing, in
which :-
Figures 1, 2 & 3 are views in transverse section showing how my invention is
carried into practical effect.
Throughout the views similar parts are marked with like letters of reference.
My improved hollow rim is constructed out of four pieces of sheet metal, one
piece forming the outer shell of the rim A, another the inner shell B, and the
others the binding strips C, C, for fixing and securing the edges of the two other
parts together.
The outer shell A is made of any desired shape to give the required stiffness
to the rim and of the required thickness to give a proper and sufficient support
for the heads of the spokes. The inner shell B is made of, the desired shape
according to the type of tyre it is intended to carry. The free edges of the outer
shell A are bent outwards to form small flanges a, a, and the free edges of the
inner shell B are bent inwards to form similar flanges b, b. Over each pair of
flanges a and b on each side of the rim are placed narrow strips of metal C having
side flanges c, c, adapted to fit over the flanges a and b of the parts A and B as
shown by Figure 1. The flanges c, c, of each plate C are turned under by a process
of rolling, drawing or folding until they assume the shape shown by Figure 2. The
thick flanges thus formed are then by a process of rolling, drawing or folding
turned downwards on the inside and outside of the rim respectively to complete
the rim as shown by Figure 3 forming well rounded and thickened edges on
each side thereof.
By this construction the inner shell B of the rim may be made of a dead size
which is so essential to the satisfactory attachment of many types of pneumatic
tyres.
Instead of making the two parts A and B out of strips of metal they may be
made out of hoops or rings of metal in the manner now well-known.
"
In the accompanying drawing a rim of the " 'Dunlop type is shown, but this is
by way of illustration only as my invention is applicable to the manufacture of all
types of hollow rims.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
I am aware that hollow rims have already been made out of two strips of
metal the free edges of which are folded together to secure the two parts
together.
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. The improved construction of hollow wheel rim, substantially as herein before
described and illustrated by the accompanying drawing.
2. In a hollow wheel rim, the combination of the part A forming the outer shell
of the rim, of the part B forming the inner shell of the rim, and of the parts C, C,
for connecting together the edges of the two parts A and B, all combined arranged
and operating, as and for the purpose set forth.
Dated this 14th day of March 1894.
