for Tricycles, Bicycles, and other similar Vehicles.
I JAMES HUDSON of Tennant Street Birmingham in the County of Warwick
manufacturer do hereby declare the nature of this invention to be as follows:-
This Invention relates to those kinds of metallic rims generally used in the vehicles
mentioned in the title. I provide a suitable strip of sheet steel which may be
either thickened in its centre or not this I draw through suitable dies (or in some
cases rolls) to the desired shape of a tube for a rim or tire; but having the joint in
the centre of the hollow of the rim. The two edges of this strip are placed flat
together and are either turned upwards or downwards into the tube and soldered, in
either case it is found that a stronger joint can be made than either the lap or the
jump joints now generally in use. When the joint is turned upwards as first
described it takes into a slot provided in the rubber tire and it is found that this
projection taking into the rubber effectually prevents the said rubber from twisting
or being forced out of the groove.

I JAMES HUDSON of Tennant Street Birmingham in the County of Warwick
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 :-
This invention relates to those kinds of metallic rims generally used in the vehicles
mentioned in the title. I provide a suitable strip of sheet steel which may be either
thickened in its centre or not this I draw through suitable dies (or in some cases rolls)
to the desired shape of a tube for a rim or tire but having the joint in the centre of
the hollow or flat of the rim.
The two edges of this strip are placed flat together and are either turned upwards
or downwards into the tube and soldered in either case it is found that a stronger
joint can be made than either the lap or jump joints now generally in use. When the
joint is turned upwards as first described it takes into a slot provided in the rubber
tire and it is found that this projection taking into rubber effectually prevents the said
rubber from twisting or being forced out of the groove or flat.
That my invention may be better understood I have annexed drawings thereof
which I will now proceed to describe.
Each figure in the drawing shews a transverse section of a rim for a cycle wheel
the said rim being made according to my invention.
I wish it to be understood that by means well known to Tube Makers I bend up at
right angles each edge of the strip of sheet steel from which I make the tube. This
said strip may be either of uniform thickness as used for making rims of the sections
shewn in figs. 1, 3, 5 and 7 or it may be thickened up in the middle as shewn in
figs. 2. 4. 6 and 8. In either case I take the strip with its bent up edges and draw
it through dies or pass it through rolls so as to make it into a tube of the proper
section. The two bent up edges or flanges being brought into juxta position as shewn
at A in each figure on the drawing and there soldered or brazed together.
In some cases I construct a rim as hereinbefore described having the joint close and
unsoldered.
Fig. 1 is a section of a rim made of a strip of uniform section with a flat outside
and the meeting flanges outwards so as to fit into a groove on a tire of semicircular
section.
Fig. 2 is a similar rim but made of a strip thickened at B.
Fig. 3 is a section of a rim similar to fig. 1 but with the flanges at A turned
inwards. This is also adapted for a tire or rubber of semicircular section.
Fig. 4 is a section of a rim similar to fig. 2 but with the flanges at A turned
inwards.

page_text: Fig. 5 is a crescent shaped rim made of a strip of uniform section with the flanges
at A projecting outwards."
Fig. 6 is similar to fig. 5 but the strip of which it is made is thickened at B.
Fig. 7 is similar to fig. 5 but it has the flanges at A turned inwards.
Fig. 8 is similar to fig. 7 but it is made of a strip which is thickened at B.
It is to be understood that in each of the figures the flanges at A are brazed
together but in some cases the brazing may be dispensed with and the space left
between them in the drawings is merely for the purpose of clearly shewing the
construction.
In figs. 1, 2, 5 and 6 the projecting flange at A takes into a corresponding groove
in the india rubber tire and assists in holding it securely.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
First. The method of making metallic tubes suitable for use in manufacturing the
rims of wheels such as are used in tricycles bicycles and other similar vehicles in the
method hereinbefore set forth and illustrated.
Second. The use of tubes made in the manner hereinbefore set forth and illustrated
in making the rims of wheels such as are used in tricycles bicycles and other similar
vehicles.
