PROVISIONAL SPECIFICATION.
Improvements in Fly or other Wheels.
We DRUITT HALPIN of No. 9 Victoria Chambers, Victoria Street Westminster S.W.
Civil Engineer and ILLIUS AUGUSTUS TIMMIS of No. 2 Great George Street West-
minster S. W. Civil Engineer do hereby declare the nature of this invention to be as
follows:-
The objects of our Invention are to construct fly wheels or other wheels of engines
(or those used for other purposes) so that they shall be readily and economically made
and yet shall have sufficient strength to resist centrifugal breaking strains when driven
at a high velocity.
With these objects in view we make the boss of the wheel and also the arms in any
convenient way and fit on them an outer ring in the shape of a channel or groove.
In this channel or groove we wind a sufficient number of layers of any suitable wire
to give the weight we require.
It is evident that the wheel rim may be made any weight in reason and whatever
the velocity it may be driven at it will be impossible that it should break.
In existing fly wheels where it is desirable to strengthen them either owing to their
being too light or where fears are entertained that they may burst we attach discs or
rings or radial bars to the existing rims of the fly wheels and then fill these troughs,
so formed, up with wire which gives the necessary additional weight and strength.

We DRUITT HALPIN of No. 9 Victoria Chambers, Victoria Street Westminster S. W.
Civil Engineer and ILLIUS AUGUSTUS TIMMIS of No. 2 Great George Street, West-
minster S.W. Civil Engineer, 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:-
The objects of our Invention are to construct fly wheels or other wheels of engines
(or those used for other purposes) so that they shall be readily and economically made
and yet shall have sufficient strength to resist centrifugal breaking strains when driven
at a high velocity.
With these objects in view we make the boss of the wheel and also the arms in any
convenient way and fit on them an outer ring in the shape of a channel or groove.
In this channel or groove we wind a sufficient number of layers of any suitable wire
to give the weight we require.
It is evident that the wheel rim may be made any weight in reason and whatever
the velocity it may be driven at it will be impossible that it should break.
In existing fly wheels where it is desirable to strengthen them either owing to their
being too light or where fears are entertained that they may burst we fix discs or
rings or radial bars to the existing rims of the fly wheel and then fill these troughs,
so formed, up with wire which gives the necessary additional weight and strength.
The annexed sheet of drawings will enable the Invention to be more readily
understood.
Figs. 1 and 2 show a built up wheel. The arms a, a support an outer groove or
channel c, e in which is wound the wire or tape w.
Figs. 3 and 4 show another mode of forming the channel c, c.

page_text: It is evident that the wheel may be made of wrought or cast metal and of any
convenient size and shape-and the amount and thickness of the wire may be as is
most convenient.
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
First. The making or forming a groove or grooves in the periphery of wheels
which are used as fly or other wheels for the purpose of putting a coil or coils of wire
or tape in substantially as and for the purposes hereinbefore described.
Secondly. The coiling or winding of wire or tape on the periphery of fly or other
wheels substantially as and for the purposes hereinbefore described.
