Improvements in and relating to the Wheels of Velocipedes and
similar Vehicles.
We, GEORGE LEONARD MORRIS, WILLIAM THOMAS WILSON, and
NATHANIEL HENRY STRICKLAND, trading as Messrs. Morris Wilson and Co. of
66 Turnmill Street, in the City and County of London, Cycle Manufacturers, and
WILLIAM JOHN LAMBERT of the "Referee" Cycle Tube Works, Station Road,
Bexley Heath, in the County of Kent, Works Manager, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to an improved construction of hollow rim for the wheels
of velocipedes and similar vehicles, and it has for its object, lightness and strength,
combined with facility of construction.
We construct our improved rim out of a strip or, length of sheet metal, which is
rolled, folded, or drawn into the desired hollow crescent section, the edges of the
strip either abutting or slightly overlapping. We then take another strip or length
of sheet metal, which we roll fold or draw into a U-shape. We then force this
U-shaped piece into the crescent shaped piece, the, curved part of the U-shaped
piece bearing against the inner sides of the edge of the said piece, and, the free ends
thereof bearing against the opposite inner side of the crescent shaped piece, the
U-shaped piece being of such a depth that, it slightly expands the crescent shaped
piece, and so causes, its edges. to be in close proximity to one another, and in close
contact with the curved part of the U-shaped piece, thus facilitating the brazing
of the joint.
The ends of the U-shaped piece are also preferably, brazed to the interior, of the
crescent,shaped piece...
The joint of the crescent shaped piece is preferably formed on the convex side
of the rim, so that with the U-shaped piece it gives a double thickness where the

We, GEORGE LEONARD MORRIS, WILLIAM THOMAS WILSON; and
NATHANIEL HENRY STRICKLAND, trading as Messrs. G. L. Morris Wilson & Co.,
of 66 Turnmill Street, in the City and County of London, Cycle Manufacturers,
and WILLIAM JOHN LAMBERT of the "Referee" Cycle Tube Works, Station
Road, Bexley Heath, in the County of Kent, Works Manager, 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 :-
Our invention relates to an improved construction of hollow rim for the wheels
of velocipedes and similar vehicles, and it'has for its object lightness, and strength,
combined with facility of construction.
We construct our improved rim out of a strip or length of sheet metal, which is
rolled, folded,,or, drawn into, the desired hollow crescent section. The edges of
this strip are on the concave or outer face of the rim but they do not meet. We

page_text: then take another strip or length of sheet metal, and we roll, fold, or draw it
until it assumes a U or D-shape in cross section, we then force this U or D-shaped
piece into the crescent shaped piece, the depth of the said piece being such that
it slightly expands the crescent shaped piece, and so causes its edges to lie in
close contact with the insertion piece, thus facilitating the brazing of the edges
of the crescent shaped piece to the insertion piece.
The edges of the insertion piece are also preferably brazed to the interior of the
crescent shaped piece.
The joint of the crescent shaped piece is preferably formed on the convex side
of the rim so that with the insertion piece gives a double thickness at the
bottom of the rim where the heads of the spokes take a bearing.
In order that our invention may be fully understood we will more particularly
describe it making reference to the accompanying drawing, in which
Figure 1 is a view in transverse section of the crescent shaped piece rolled,
folded, or drawn into approximately the desired section of the rim.
Figure 2 is a view in transverse section of one form of insertion piece, and
Figure 3 is a view in transverse section of the finished rim.
Figure 4 is a view in transverse section of another form of insertion piece, and
Figure 5 is a view in transverse section of a. finished rim embodying that
construction.
Figures 6, 7, and 8 are views in transverse section of the crescent shaped piece,
the insertion piece, and the finished rim, respectively, showing the use of another
form of insertion piece.
Figures 9 and 10 are views in transverse section of rims constructed according
to our invention and having the joint of the crescent shaped piece formed on
the convex face of the rim. Throughout these views similar parts are marked
with like letters of reference.
Our improved hollow rim consists of two essential parts, the outer part A. which
is of approximately the required shape and section, and the inner or insertion
piece B. The outer part A. is formed of a strip or length of sheet metal rolled,
folded, or drawn into the desired section and having its edges a, a, either on the
outer or concave face as shown by Figures 1, 3, 5, 6, and 8, of the accompanying
drawing, or on the inner or convex face as shown by Figures 9 and 10 of the
accompanying drawing. The edges a,. a, do not overlap or even abut against each
other. The inner or insertion piece B may be either of a U-shape as shown by
Figures 2, 3, and 9 of the accompanying drawing, or of a D-shape as shown by
Figures 4, 5, 7, 8, and 10 of the accompanying drawing. The depth of this
insertion piece B is slightly greater than the interior depth of the outer part A so
that when it is forced into the said outer part it slightly expands the said part and
causes its edges, a, a, to lie firmly and closely against the inner or insertion
piece. Bas shown by Figures 3, 5, 8, 9, and 10 of the accompanying drawing. The
joints of the edges a, a, with the inner or insertion piece B are then brazed, as are
also the point or points of junction of the said inner or insertion piece with the
opposite part of the rim.
To give increased strength to the rim at that part adapted to receive the spokes,
the insertion piece B is preferably made of the section shown by Figures 5 and 8 of
the accompanying drawing.
In this construction of rim the brazing of the joint or joints is materially
facilitated, while the rim produced has increased strength without increase of
weight owing the use of a thinner gauge of sheet metal and a better distribution
thereof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
-
1. The improved construction of hollow rim for the wheels of velocipedes and
similar vehicles, as set forth.

page_text: 2. In a hollow rim for velocipedes and similar vehicles, the combination of an
outer part of approximately the desired shape of the finished rim and having its
edges not meeting, and of an inner or insertion piece of a U-shape in cross
section, combined, arranged, and operating as and for the purpose set forth.
3. In a hollow rim for velocipedes and similar vehicles, the combination of an
outer part of approximately the desired shape of the finished rim and having its
edges not meeting, and of an inner or insertion piece of a D-shape in cross
section, combined, arranged, and operating as and for the purpose set forth.
4. A rim of the special construction and configuration shown in Figures 1, 2,
and 3 of the accompanying drawing, and substantially as herein described.
5. A rim of the special construction and configuration shown in Figures 4 and 5
of the accompanying drawing, and substantially as herein described.
6. A rim of the special construction and configuration shown in Figures 6, 7,
and 8 of the accompanying drawing, and substantially as herein described.
7. A rim of the special construction and configuration shown in Figure 9 of the
accompanying drawing, and substantially as herein described.
8. A run of the special construction and configuration shown in Figure 10 of the
accompanying drawing, and substantially as herein described.
