Improvements in the Manufacture of Weldless Rims, Hoops, and
like Articles.
We, RICHARD SMITH-CASSON of Exchange Chambers, Birmingham, in the
County of Warwick, Merchant, and MURRAY PRESTON of 64 Wilton Road,
Sparkhill, in the County of Worcester, near Birmingham, Cycle Manufacturer, do
hereby declare the nature of this invention to be as follows:-
In carrying out our invention we take a circular or approximately circular sheet
of iron, steel, or suitable metal and press it into a cylinder of the required diameter
and shape, forming as it were a large thimble; it is then taken to a lathe or
suitable machine for the purpose, and rims, rings, or other suitable articles are cut
off, which if necessary are placed into rollers and shaped into any section or
diameter that may be required.
Preferably we make the thimble of the diameter of the rim or size required, so
that the rolling process acts only to obtain uniformity in size and section.

Improvements in the Manufacture of Weldless Rims, Hoops, and
like Articles.
We, RICHARD SMITH-CASSON of Exchange Chambers, Birmingham, in the
County of Warwick, Merchant, and Manufacturer and MURRAY PRESTON of
64 Wilton Road, Sparkhill, in the County of Worcester, near Birmingham, 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:
-
Our invention relates to certain improvements in the manufacture of weldless
rims, hoops, and like articles.
In carrying out our invention we take a circular or approximately circular sheet
of iron steel or suitable metal and press it into a cylinder or tube of the required
diameter and shape, forming as it were a large thimble; it is then taken to a lathe
or suitable machine, for the purpose, and rims, rings or other suitable articles are
cut off, which if necessary are passed between rollers and shaped into any section
or diameter that may be required.
Preferably we make the thimble of the diameter of the rim or size required, so
that the rolling process acts only to obtain uniformity in size and section.
In the accompanying drawings:
Fig. 1 is a sectional elevation of a die and plunger of a press with a sheet of
metal between same.
Fig. 2 is a view of the cylinder or thimble produced.

page_text: Fig. 3 is a view showing how the cylinder or thimble is divided up into a number
of rings, and
Fig. 4 is a view of a ring so produced.
In the process of pressing, the plunger a forces the sheet of steel b into the die c,
and forms the cyliuder, tube or thimble e. The cylinder is then divided up into a
number of rings which are preferably of the diameter, or approximately the
diameter of the wheel, rim, or other article to be produced therefrom, so that the
necessity of any spinning or enlarging processes are obviated. The subsequent
operation if required would then consist in rolling or forming such ring into the
shape or section required without substantially increasing its diameter, although it
will be evident that a certain increase in diameter may be imparted by such rolling
or shaping. In this way we are able to produce from a cylinder, tube, or thimble
formed by one or more pressing or similar operations a number of rings with but
very little waste of material.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :-
1. In the manufacture of weldless rims, hoops, and like articles, the production
from a sheet of metal, of a cylinder, tube, or thimble, and the subsequent division
of same into a number of rings, substantially as described.
2. In the manufacture of weldless rims, hoops, and like articles, the production
from a sheet of metal, of a cylinder, tube or thimble of approximately the diameter
of the finished article, the subsequent division of same into a number of rings, and
the rolling or shaping of same without any intermediate enlarging process,
substantially as described.
3. A weldless ring, hoop, or like article produced in the manner substantially as
set forth in the preceding claims.
