PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Gear Wheels.
We, FRED ROWCLIFFE and JOHN ARTHUR ROWCLIFFE, both of Atlas Works,
Levenshulme, near Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manufacture of gear wheels the object being to
reduce the noise at present generally resulting from the working of toothed
gearing and to produce wheels which are cheap and durable.
The invention consists in forming the gear wheels of discs, the materials of
which are of a noiseless character such as hide or leather in combination with
metallic discs.
These discs may be stamped moulded or cut, to the desired form with teeth
and are clamped or held together by rivets, bolts, or otherwise, to form a gear
wheel of the desired breadth.
The metal or more durable and stronger discs may be at the outside of the
wheels, or in the centre, or otherwise disposed among or in combination with the
discs which are used for their noiseless property.

Improvements in the Manufacture of Gear Wheels.
We, FRED ROWCLIFFE and JOHN ARTHUR ROWCLIFFE, both of Atlas Works,
Levenshulme, near Manchester, in the County of Lancaster, Engineers, 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:-
1
This invention relates to the manufacture of gear wheels used for the trans-
mission of power or motion in various kinds of machinery, the object being to
reduce the noise at present generally resulting from the working of toothed
gearing and to produce wheels which are at the same time cheap and durable.
The invention consists in forming the gear wheels of a series of discs, the
materials of which are of a noiseless character such as leather, in combination with
discs of metal or other material of a comparatively harder stronger or more
durable nature.

page_text: These discs may be stamped, moulded or cut, to the desired form, with teeth,
and are clamped or held together by rivets, bolts, or otherwise, to form a gear
wheel of the desired breadth, or circular blanks may he formed of a series of plain
discs clamped, rivetted, bolted, or otherwise connected or united together and
the teeth afterwards cut or formed thereon.
The metal or more durable and stronger discs may be at the outside of the
wheels, or in the centre, or they may be otherwise disposed among or in com-
bination with the leather, or other dises which are used for their noiseless
property.
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:-
The improvements in the manufacture of gear wheels used in various kinds of
machinery consisting in the combination of a series of discs of leather, or other
suitable material having noiseless qualities, with dises of metal or other material
of a comparatively harder stronger or more durable nature substantially as and
for the purposes herein before mentioned.
