PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Grooved Metal Tyres
for the Wheels of Certain Vehicles.
I WILLIAM BEALE of 33 Totteridge Road Battersea in the County of Surrey
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and in the manufacture of grooved
metal tyres (of an undercut or dovetail form in cross section) for receiving rubber
or other clastic tyres for the wheels of certain vehicles such as hansom cabs
carriages etcetera.
N
The metal tyre according to one part of my present invention is formed with
concave at or near the centre of the inside side of the base with overhanging edges
thereto so that a second dovetail or undercut section is thereby formed and thus
gives additional security in holding the elastic tyre. On the underside of the base
of the metal tyre a swelling or raised surface is formed which fits into a corre-
sponding groove formed in the wood felloe of the wheel.
The prepared length of metal to form the tyres is passed through a pair of rolls
which partly turn up the sides and also turns in the edges thereof to form the
turned in edges (or bead) which ultimately forms the undercut or retaining edges
or a bead may be previously formed therein. Further a concave or depressed
surface curved or otherwise is also formed in the base of the tyre by means of
corresponding forms on the rolls. The operation thus far being performed all in
one pair of rolls or by two or more pairs if desired.
The metal may then be passed through another rolling operation to straighten
the middle part somewhat.
The next pair of rolls (or openings for the next rolling operation) have rectangular
or suitably shaped grooves in their peripheries with a mandril arranged in between
same and receive and roll the metal on its side on the said mandril thus turning
in the sides or outer edges to the required degree and so causing it to assume its
final shape the mandril serving to keep it of the exact shape required and it is
then (if desired) passed through a pair of finishing rolls which are formed to
correspond with the concave surface on the inside of the base of the tyre and thus
the length of metal is made true and of the exact shape required.
My invention of rolling metal tyres upon a mandril as described so as thus to
turn in their sides may be adapted to other sections of tyres besides the particular
tyre just described (as for instance such metal tyres as those shown and described
in the Specifications and drawings of an invention for which I have received
Letters Patent No. 18923 of 1889) the rolls being formed accordingly so as to give
any required shape or form in cross section to such other metal tyres.
Each separate rolling operation may be performed by an independent pair of
rolls or one pair of rolls only may be arranged for performing all the several rolling
operations as desired.

Improvements in and in the Manufacture of Grooved Metal Tyres
for the Wheels of Certain Vehicles.
I WILLIAM BEALE of 33 Totteridge Road Battersea in the County of Surrey
.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 improvements in-and in the manufacture of grooved
metal tyres (of an undercut or dovetail form in cross section) for receiving rubber
or other elastic tyres for the wheels of certain vehicles such as hansom cabs
carriages etcetera.
The metal tyre may be formed with a swelling or raised surface on the underside
of, the base of the metal tyre and such swelling or raised surface fits into a corre-
sponding groove formed in the wood felloe of the wheel.
The prepared length of metal to form the tyres is passed through a pair of rolls
which partly turn up the sides and also turns in the edges thereof to form the
turned in edges (or bead) which ultimately forms the undercut or retaining edges
(or a bead may be previously formed thereon).
The operation thus far being performed all in one pair of rolls or by two or
more pairs if desired.
The metal may then be passed through another rolling operation to straighten
the middle part somewhat.
The next pair of rolls (or openings for the next rolling operation) have
rectangular or suitably shaped grooves in their peripheries with a mandrel arranged
in between same and receive and roll the metal on its side on the said mandrel
thus turning in the sides or outer edges to the required degree and so causing it
to assume it's final shape the mandrel serving to keep it of the exact shape required
and it is then (if desired) passed through a pair of finishing rolls and thus the
length of metal is made true and of the exact shape required.
My invention of rolling metal tyres upon a mandrel as described so as thus to
turn in their sides may be adapted to other sections of tyres besides the particular
tyre just described (as for instance such metal tyres as those shown and described
in the Specifications and drawings of an invention for which I have received
Letters Patent No. 18923 of 1889) the rolls being formed accordingly so as to give
any required shape or form in cross section to such other metal tyres.
Each separate rolling operation may be performed by an independent pair of
rolls or one pair of rolls only may be arranged for performing all the several rolling
operations as desired.
And in order that my present invention may be easily understood and readily
carried into practice I will proceed to further describe same with reference to the
sheet of drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents the first "gate" or opening in the rolls for partly turning
up the outer edges.
Figure 2 represents the second "gate" or opening which further turns up
the edges.
Figure 3 represents a further advanced stage of the rolling-and to this part of
the rolling so far as described up to. this stage shown in Figure 3 I make no
separate claim whatever as same is well understood in the trade.
Figure 4 represents the essential feature of my present invention viz. the
mandral inconted and

page_text: Figure 5 shows another form of mandrel-in this case said mandrel is formed of
the outer edge and side surface of a revolving wheel or drum capable of rotating
on its axis-such axis being vertical or at right angles or thereabouts to the plane
of the rolling drums.
The raised surface x may or may not be formed as desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In rolling grooved metal tyres the use and application of a mandrel such as a
substantially as and for the purposes hereinbefore described and illustrated in the
drawings hereunto annexed.
2. In rolling grooved metal tyres I claim the combination with any suitable rolls
of a mandrel or mandrels of any suitable and desired shape substantially as and
for the purposes set forth.
