Improvements in Felloes or Rims for Wheels.
We, CHARLES KINGSTON WELCH, of The Hollies Eaton Road, Coventry in
the County of Warwickshire, Engineer, and HARVEY DU CROS, Chairman of the
Pneumatic Tyre and Booth's Cycle Agency Limited, of Oriel House, Westland
Row, Dublin, in the County of Dublin, Ireland, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to an improved rim adapted for wheels of velocipedes and
other vehicles and has for its object to provide a rim which is especially fitted for
receiving a pneumatic or other elastic tyre which is secured thereon by means of
non-elastic cores of wire or other suitable material secured in the edges or sides of
the tyre or tyre cover. Such methods of securing tyres to wheels are described in
the Specification of British Letters Patent No. 14563 A.D. 1890 granted to the
said Charles Kingston Welch.
According to our invention we make our improved rims hollow and in two parts,
one of the said parts being secured to the other by brazing or other suitable
means. The outermost portion of our improved rim is approximately U-shaped
in section and has a channel or shoulder on both sides of a central depression.
The innermost portion of the rim is in the preferred form approximately semi-
circular in section and its edges, which are bent outwards, are brazed or otherwise
secured to the lower or bottom parts of the side channels or shoulders in the
outermost portion of the rim hereinabove mentioned. Or we may roll the bottom
in one piece with the shoulders or channels and edges and fit and braze or
otherwise fasten an inner strip of suitable shape bridging between the two shoulders
or channels.
The side channels or shoulders of our improved rim form convenient seatings for
the wires or other non-elastic cores which are contained in the edges or sides of the
tyre or tyre cover and which serve to keep the tyre in position on the wheel. The
central groove or channel affords means whereby a pneumatic tyre or cover can be
slipped on to and off the rim when the air tube is deflated as described in the said
Specification No. 14563 of 1890.
The edges of our improved rim are preferably turned or bent outwards or may
be beaded so as to prevent the tyre or tyrė cover from being cut or damaged by
the same.
Our improved rim is made of steel or other suitable material, it is very light
and at the same time possesses the desirable qualities of great strength and
stiffness.

COMPLETE SPECIFICATION.
Improvements in Felloes or Rims for Wheels.
We, CHARLES KINGSTON WELCH, of The Hollies, Eaton Road, Coventry in
the County of Warwick, Engineer, and HARVEY DU CROS, Chairman of the
Pneumatic Tyre and Booth's Cycle Agency Limited, of Oriel House, Westland
Row, Dublin, in the County of Dublin, Ireland, 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 rim adapted for wheels of velocipedes and

page_text: other vehicles and has for its object to provide a rim which is especially fitted for
receiving a pneumatic or other elastic tyre which is secured thereon by means of
non-elastic cores of wire or other suitable material secured in the edges or sides of
the tyre or tyre cover. Such methods of securing tyres to wheels are described in
the Specification of British Letters Patent No. 14563 A.D. 1890 granted to the
said Charles Kingston Welch.
According to our invention we make our improved rims hollow and in two
parts, one of the said parts being secured to the other by brazing or other suitable
means.
In the accompanying drawing we shew various sections of rims constructed
according to our invention.
In all the figures A refers to one of the parts of the rim and B refers to the
other
part.
Referring to Figure 1, the part A is approximately U-shaped in section and has
a central depression A' and a channel or shoulder A2 A2 on each side of the said
depression. The part B of this rim is approximately semi-circular in section and
has its edges B₁ bent outwards and brazed soldered or otherwise secured as by
screws or rivets for example to the lower parts of the channels or shoulders A* A*
of the part A.
In Figure 2 is shewn the section of a rim in which the part A with its
shoulders A³ A forms the innermost part of the rim the spokes of the wheel being
attached to the bottom of the central channel A'. The part B bridges across the
shoulders A' A' as shewn.
The rim shewn in Figure 3 is a modified form of that hereinabove described
with reference to Figure 1. The shoulders A'A' are somewhat modified as the sides
of the rim are bent in so as to overhang the channels as shewn at A³. The part B
is practically the same shape as in the rim shewn in Figure 1.
In Figures 4, 5 and 6 the part A of the rim has a similar shape to the corre-
sponding part in Figure 2. The part B however is not semi-circular but formed
of a strip having its edges B' bent over as shewn. The said edges form. the
shoulders or side channels and the space between the bent edges forms the central
depression. In Figure 6 the strip is wider so that the edges B¹ meet in the middle
line, the part B being thus made very strong and rigid. The two parts are secured
together in the same manner as herein before described with reference to Figure 2.
The side channels or shoulders of our improved rim form convenient seatings for
the wires or other non-elastic cores which are contained in the edges or sides of the
tyre or tyre cover and which serve to keep the tyre in position on the wheel. The
central groove or channel affords means whereby a pneumatic tyre or cover can be
slipped on to and off the rim when the air tube is deflated as described in the
beforementioned Specification No. 14563 of 1890.
The edges of our improved rim are turned or bent outwards or they may
be beaded so as to prevent the tyre or tyre cover from being cut or damaged by
the same.
Our improved rim is made of steel or other suitable material, it is very light
and at the same time possesses the desirable qualities of great strength and
stiffness.
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 :
The improved hollow rims for wheels constructed of two parts secured together,
substantially as described with reference to any of the forms illustrated in the
accompanying drawings, for the purposes specified.
