PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Tyres or Rims for Wheels.
1, SIDNEY STUART WALKER Mechanical Engineer of Woodside Knowle in the
County of Warwick do hereby declare the nature of this invention to be as
follows:-
My improvement consists of making tyres' or rims for wheels in the following
anner.
I take a bar of Iron, Steel or other Metal preferably of oblong section; I cut or
punch a longitudinal slot in this bar leaving the ends uncut for a distance equal to
about the thickness of one side the ends of the bar are to be rounded. The bar
ofter having been cut or punched as described above is opened out preferably by
pressing or drifting with a taper mandril or plug. The opened bar is now placed
between the rolls of an ordinary tyre rolling machine and rolled out to the required
size. The tyres or rims are then made jointless or seamless.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Tyres or Rims for Wheels.
I, SIDNEY STUART WALKER Mechanical Engineer of Woodside Knowle in the
County of Warwick, 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 has for its object "Improvements in the manufacture of rims for
wheels" and refers particularly to the manufacture of tyres for wood wheels of all
kinds of Vehicles by which I provide rims commonly known as jointless and weld-
less tyres in a very cheap effective and economical manner.
In order that my invention may be clearly understood and more easily carried
into practice I have added a sheet of drawings hereto upon which I have fully
illustrated my improved mode of manufacture.
Figure 1 is a view of the billet or bar of iron from which my rim is formed.
Figure 2 is a similar view of the bar but after the process of cutting and also
rounding th ends.
Figure 3 is a cross section through Figure 2.
Figure 4 is an elevation of the bar when drifted or otherwise opened.
In carrying my invention into effect for heavy rims I take a bar A of iron steel
or other metal preferably of the oblong section shewn in which I cut or punch the

page_text: longitudinal slot a¹ leaving the ends a³ uncut for a distance equal to about the
thickness of the sides a' and I also round the ends of the said bar as shewn at a².
The bar after having been cut or punched as above described is opened out as
shewn by Figure 4 preferably by pressure or drifting with a taper mandrel or plug
atter which it is placed between the rolls B, B' of an ordinary tyre rolling machine
and rolled out to the required size as shewn in' diagram by dotted lines A5 in
Figure 4. The rolls may be grooved to form the rim or tyre of any desired
section. In the case of rims of thin cross section, instead of employing bar iron I
may take a thin flat strip of iron steel or other metal of suitable thickness and width
and treat it in a similar manner to that of the bar.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I teclare that what
I claim is
1. The manufacture of rims for wheels substantially such as and for the purpose
herein set forth and shewn upon the accompanying drawings.
2. The manufacture of rims for wheels from iron or steels bars or billets having
1ounded ends substantially as and for the purpose herein set forth and shewn.
Dated this First day of September 1897.
