I, PIERRE LORMANT of The London and Midland Bank Chambers, Brighton,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus which can be used as a motor driven by
fluid under pressure or as a pump for forcing fluid when it is driven by extraneous
power.
Within a casing two cylinders are arranged to revolve on parallel axes connected
by external gearing so that they revolve with equal velocity in opposite directions,
their circumferences touching each other in the middle line of the casing. Each
cylinder has several radial slots in which blades are fitted to slide, these blades
having at each end projections engaged in cam grooves formed in the covers of the
casing.
These grooves are of such form that the blades during a large portion of their
revolution are protruded from the cylinders so that their edges rub against the
interior of the casing on its opposite sides, but before reaching the middle line
where the cylinders touch each other, the blades are drawn in to the bodies of the
cylinders.
Fluid under pressure admitted at the one side of the casing and pressing on the
protruded blades causes the cylinders to revolve, and is discharge l at the other
side of the casing, the apparatus thus acting as a motor, or, conversely, when the
cylinders are caused to revolve by extraneous power, fluid is drawn into the casing
on the one side and discharged at the other side, the apparatus theu acting as
a pump.

An Improved Rotary Fluid Motor or Pump.
I, PIERKE LORMANT, of The London and Midland Bank Chambers, Brighton,
Gentleman, 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 apparatus which can be used as a motor driven by fluid
under pressure or as a pump for forcing fluid when it is driven by extraneous power
as I shall describe with reference to the accompanying drawings, Fig. 1 is a
longitudinal and Fig. 2 is a transverse section of a motor or pump according to
my invention.

page_text: Within a casing C two cylinders are arranged to revolve on parallel axes A A
connected by external gearing so that they revolve with equal velocity in opposite
directions, their circumferences touching each other in the middle line of the
casing.
Each cylinder has several radial slots in which blades B are fitted to slide, these
blades having at each end projections engaged in cam grooves G formed in the
covers of the casing.
These grooves are of such form that the blades during a large portion of their
revolution are protruded from the cylinders so that their edges rub against the
interior of the casing C on its opposite sides, but before reaching the middle line
where the cylinders touch each other, the blades are drawn in to the bodies
of the cylinders.
Fluid under pressure admitted by an inlet I at the one side of the casing and
pressing on the protruded blades causes the cylinders to revulve, and is discharged by
an outlet O at the other side of the casing, the apparatus thus acting as a motor,
or, conversely, when the cylinders are caused to revolve by extraneous power,
fluid is drawn into the casing at I on the one side and discharged at O on the other
side, the apparatus then acting as a pump.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is :-
A rotary fluid motor or pump constructed and operating substantially as
described with reference to the drawings.
