1, LEONARD BURRELL, of 37, Rua de Santa Luzia, Rio de Janiero, in the United
States of Brazil, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a rotary motor actuated by any fluid either liquid
or gaseous.
Motion is obtained by the effect of the displacement of weighted
pistons working in cylinders which project radially from a common centre or hub
around which they are placed. The bnb rotates upon a hollow axle. This hollow
axle or pipe is divided longitudinally by an inner vertical partition and forms two
contiguous passages provided with orifices corresponding to orifices formed in the
inner ends of the cylinders. One of these passages serves for the inlet and the
other for the outlet of fluid. to and from the cylinders.
The outer ends of the cylinders are connected together by a pipe.
The apparatus works as follows:-Suppose the cylinders to be at an angle of 45°
with respect to the ground the pistons in the two upper cylinders which I will call
1 and 2 rest upon the outer ends of their respective cylinders and the pistons in
the two lower cylinders which I will call 3 and 4 upon the inner end. By means of
an orifice which is then again closed the space comprised by the pipe connecting
the outer ends of the cylinders, the ends of the cylinders 3 and 4 and the portion
of the cylinders 1 and 2 above the pistons is filled completely with oil, water or
other non-compressible fluid in such a manner as to expel all air from this space;
then by giving access to the motor fluid by the inlet passage in the hollow axle the
pressure of the fluid acts in the cylinders 2 and 3 whilst the cylinders and 4 are
in communication with the outlet duct.
The motor fluid after having filled the cylinder 3 drives the piston in cylinder 2
outwards expelling the liquid in the outer end of the cylinder into the pipe
connecting the ends of the cylinders, thereby forces the piston in cylinder 4
inwards towards the centre a distance exactly equal to that traversed by the piston
in cylinder 2 from the centre. The equilibrium of the system being thus broken
the machine commences to rotate.
In the movement of rotation of the motor when the cylinders are on one side of
the axis of rotation their respective pistons are always propelled by the motor fluid
from the centre towards the pipe connecting the outer ends of the cylinders and
when these same cylinders pass to the other side of the axle their pistons are always
brought back by the transmission liquid towards the centre.
To reverse the machine means are provided for interchanging the supply and
exhaust passages.
This engine may also be employed as a meter for measuring liquids and gases.

I, LEONARD BURRELL, of 37, Rua de Sauta Luzia, Rio de Janeiro, in the United
States of Brazil, 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 has for its object a rotary motor actuated by any fluid either liquid
or gaseons.
Motion is obtained by the effect of the displacement of weighted
pistons working in cylinders which project radially from a common centre or hub
around which they are placed. The hub rotates upon a hollow axle. This hollow
axle or pipe is divided longitudinally by an inner vertical partition and forms two
contiguous passages provided with orifices corresponding to orifices formed in the
inner ends of the cylinders. One of these passages serves for the inlet and the
other for the outlet of fluid to and from the cylinders.
The outer ends of the cylinders are connected together by a pipe.
Figure 1 is a vertical central section of the engine, and Figures 2 and 3 are
sections on the lives 2-2 and 3-8 Figure 1 when the cylinders are in those
positions.
1, 2, 3 and 4 are cylinders fixed to a hollow central shaft working in fixed
bearings b. The shaft is closed at one end and at the other has a stufling
box e through which passes a pipe divided into two by a partition e fitting the
inside of the hollow shaft and extending to its end. Fluid is supplied by the half d
of the pipe and escapes by the other half. The cylinders are connected to the
inside of the hollow shaft by ports f. ggy and y' are heavy pistous within
the cylinders. The outer ends of the cylinders are all connected together by the
pipe 7.
The apparatus works as follows:-Suppose the cylinders to be at an angle of 45°
with respect to the ground the pistons in the two upper cylinders say 1 and 2 rest
upon the outer ends of their respective cylinders, and the pistons 3g in the two
lower cylinders 3 and 4 upon the inner ends. By means of an orifice (not shown)
which is then again closed, the space comprised by the pipe connecting the outer
ends of the cylinders, the ends of the cylinders 3 and 4 and the portion of the
cylinders 1 and 2 above the pistons g¹y is filled completely with oil, water or other
non-compressible fluid in such a manner as to expel all air from this space; then by
giving access to the motor fluid by the inlet passage d in the hollow axle the
pressure of the fluid acts in the cylinders 2 and 3 whilst the cylinders 1 and 4 are in
communication with the outlet duct ².
The motor fluid after having filled the cylinder 3 drives the piston 2 in cylinder 2
outwards expelling the liquid in the outer end of the cylinder into the pipe h con-
necting the ends of the cylinders, thereby forces the piston g in cylinder 4 inwards
towards the centre a distance exactly equal to that traversed by the piston g² in
cylinder 2 from the centre. The equilibrium of the system being thus broken the
machine commences to rotate.
h
In the movement of rotation of the motor when the cylinders are on one side of
the axis of rotation their respective pistons are always propelled by the motor fluid
from the centre toward the pipe connecting the outer ends of the cylinders and
when these same cylinders pass to the other side of the axle their pistons are
always brought back by the transmission liquid towards the centre.
To reverse the machine means are provided for interchanging the supply and
exhaust passages ¹².

page_text: This engine may also be employed as a meter for measuring liquids and
gases.
Having now particularly described and ascertained the nature of any said inven-
tion and in what manner the same is to be performed I declare that what I
claim is -
1. The combination of two or more cylinders connected together at one end and
free to rotate about an axis, heavy pistons in the cylinders and means for alternately
connecting the other ends of the cylinders to supply and exhaust passages.
2. Rotary engines substantially as described and shown in the drawings.
