We JOSEPH ARMYTAGE WADE of Hornsea in the East Riding of the County of
York Timber Merchant and JOHN CHERRY of Hornsea Aforesaid, Mechanical
Engineer and Brick and Tile Works Manager, do hereby declare the nature of this
Invention to be as follows:
The object of our invention is to produce an improved rotary engine which may
be driven by steam or other suitable motive power and which is simple of con-
struction and direct acting.
And the invention consists in the arrangement of a single or double or further
multiplied type of rotary engine with a dise or dises provided with a piston or
pistons at the outer circumferences thereof, such discs being constructed and
arranged so as to revolve in a circular chamber or chambers as required. The
said dises being mounted on the main shafts of the engine and thereby commu-
nicating their revolving motion to the said shafts.
And our invention is carried out as follows:-
In one of the double types of engine the two working discs revolve face to face
in close contact but have a steam passage or chamber round them excepting at
their point of contact. Each disc is provided with a suitable recess so as to receive
the piston of the other disc at the required point in their revolution.
Or the two working dises furnished with pistons and steam channels may be
separated by another dise not having a steam chamber round it and not being
furnished with pistons or channels and in that case the recess would be formed
in the said separating disc, so as to receive the pistons of the working disc
alternately as required. The three dises in this latter form of engine also revolve
closely together at their faces excepting so far as the piston and recess portion of
the dises are concerned. The form of the pistons may be round, square or of other
shape as preferred, and the recess will also vary to suit the form of piston and the
circular chamber or passage will be formed accordingly.
In the single type of engine there is one working disc with a piston at its
circumference working in contact with another dise "provided with a recess as
above mentioned, but destitute of piston and channel for the supply of motive power

page_text: In both types of engines the steam or other suitable agent is caused to enter and
escape directly from the said working discs, such dises having a curved channel
formed in one or both sides of each for the purpose, such curved channel com-
municating with the inlet for steam or other agent during part of the revolution of the
working dises; a suitable opening from the curved channel also allows the steam
or other agent to pass into the passage or chamber surrounding the circumference
of the working dises, and from such passage or chamber it finally escapes through
an outlet in the outer case of the engine as required.
The discs being caused to revolve in close contact at their circumferences, in this
way form a stop or abuttal for the steam or other motive power, and thus enables
the said motive power to thrust the pistons forward as required, thereby dispensing
with the need of valves except for starting, stopping or reversing, which operations
may be performed by the aid of suitable valves and levers.
The starting or reversing may be accomplished by providing another engine on
the same shaft having its piston set at a different angle and which although it
may receive its working steam or other motive power from the first engine may
have an independent supply by means of an extra valve so that these operations
will certainly be performed instantaneously for if the supply of steam do not catch
the one engine at the right angle it is sure so to catch the other. Valves are provided
for starting stopping and reversing but we do not confine ourselves to any particular
form of valve.
The above mentioned arrangements of both single and double engines may he
applied to a number of engines (by the same supply of steam or other agent) by their
being mounted on the same shaft or shafts, if desired or even if mounted on shafts
other than that on which the engine is mounted which receives its supply direct from
the boiler the supply to these connected engines would be conveyed in pipes from
the outlet of the one to the inlet of the other and might finally escape into the atmo-
sphere or into a condenser or tank.
Governors and Fly wheels may be applied in the usual manner.

We JOSEPH ARMYTAGE WADE of Hornsea in the East Riding of the County of
York Timber Merchant and JOHN CHERRY of Hornsea aforesaid Mechanical Engineer
and Brick and Tile Works Manager 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 object of our Invention is to produce an improved rotary engine which may be
driven by steam or other suitable motive Agent and which is simple of construction
and direct acting.
And the Invention consists in the arrangement of a single or double or further
multiplied type of rotary engine with a disc or discs provided with a piston or pistons
at the outer circumference thereof, such discs being constructed and arranged so as to
revolve in a circular chamber or chambers as required.-The said discs being mo ated
on the main shafts of the engine and thereby communicating their revolving motion
to the shafts.
And our Invention is carried out as follows:-
In one of the double types of engine the two working discs revolve face to face in
close contact but having a steam passage or chamber round them excepting at their
point of contact. Each disc is provided with a suitable recess so as to receive the
piston of the other disc at the required point in their revolution.
Or the two working discs furnished with pistons and steam channels may be
separated by another disc not having a steam chamber round it and not being
furnished with piston or channels, and in that case the recess would be formed
in the said separating disc so as to receive the pistons of the working dises
alternately as required. The three discs in the latter form of engine also revolve
closely together at their faces excepting so far as the piston and recess portion of
the discs are concerned. The form of the pistons may be round, square or of other
shape as preferred, and the recess will also vary to suit the form of piston and the
circular chamber or passage will be formed accordingly.
In the single type of engine there is one working disc with a piston or pistons
at its circumference working in contact with another or two other discs provided
with recess as above mentioned but without piston and channel for the supply of
motive power.
In theso types of engines the steam or other suitable agent is caused to enter and
escape directly from the said working discs, such discs having a curved channel
formed in one or both sides of each for the purpose; such curved channel commu-
nicating with the inlet for steam or other agent during part of the revolution of
the working dises a suitable opening from the curved channel also allows the steam
or other agent to pass into the passage or chamber surrounding the circumference
of the working discs, and from such passage or chamber it finally escapes through
an outlet in the outer case of the engine as required.
The discs being caused to revolve in close contact at their circumferences in this way
form a stop or abuttal for the steam or other motive power and thus enables the said

It will be noticed that in the case of figures 5. 6 and 7. 8 instead of only one
roller valve B2 (as shewn in figures 3 and 4) being provided, two conical roller
valves are shewn in figures 5 and 6 and two cylindrical roller valves in figures 7
and 8 which are arranged with suitable gaps so as to alternately engage the
piston or piston C as required.-Suitable bevelled gearing L L is also employed in
the form of engines shewn in figures 5 and 6.
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 :-
First. The arrangement of a single type of engine shewn in figures 3 and 4
consisting of a disc B, piston roller valve B2 on the respective working shafts
connected by gearing L. L. and with inlet and outlet passages for steam or other
motive agent and also the steam channel E all substantially as described with
reference to those figures.
