Improvements in Rotary Engines, Motors, Pumps, and the like.
We, CHARLES Roux, Civil Engineer, and PHILIPPE BOUHEY, Civil Engineer,
both residing at Montbard (Cote-d'Or,) in the Republic of France, do hereby
declare the nature of this invention and in what manner the same is to be per-
relates to a motor of spheroidal form suitable for use with steam, air, or hydraulic
statement:—
This invention for improvements in motive power apparatus pumps and the like
relates to a motor of spheroidal form suitable for use with steam, air, or hydraulic
power, and for exhausting or forcing gas or water or other fluid.
It is characterised by a mechanism effecting a continuous rotary motion without
shocks, at very high speed under the action of a gas, liquid or other fluid.
The cylinder or casing of the mechanism comprises two separate parts or
truncated spheres rigidly connected together with an intermediate separating
circular disc ball shaped at its centre. This plate divides the interior capacity
of the spherical cylinder or casing into two parts surrounding the pistons. The
interior conical faces or surfaces of this plate receive on opposite sides at the ex-
tremities of a diameter and situated in the same plane a fixed partition, that
penetrates with slight friction, in a recess in the spheroidal piston oscillating
about the partition and forms a radial abutment for the motive fluid.
Fig. 1 shows in vertical section, a spheroidal motor with its two chambers, or
distinct spheroidal capacities, in each of which works the spheroidal truncated
piston. Fig. 2 shows in front view, one of the two small fixed separating parti-
tions that bear against the circular plate extending from the interior periphery of
each of the chambers to the ball. Figs. 3 and 4 show a variation of the arrange-
ment shown in Fig. 2. Fig. 5 is an elevation of the motor in front of which is shown
a double-valved cock. The steam enters by, the upper orifice and exhausts by the
lower orifice of this cock. Figs. 6 and 7 are two sections, one at the left (Fig. 6)
of the left hand side casing, the other at the right (Fig. 7) of the right hand side
casing; on each of these sections is shown, in its place the projection of the small
separating partition.
The casing or semi-spherical coverings K, K' form a chamber that the circular
fixed plate B formed at its centre as a ball (Fig. 1) separates into two distinct
parts in which work the two spheroidal pistons S, St provided with packing rings p pi
bearing against the interior surface of the casing; the front of the piston is in the
form of a cone that bears by successive generatrices as it oscillates on the surface
of the partition B. These two pistons, either have the same radius R; or one, S¹,
has a radius R', larger than that of the radius R as shown in Fig. 1 in dotted lines
so as to allow for any expansion desired of the motive fluid.
The contact between each of the successive generatrices of the conical part S
or S¹, with the correspondent generatrices of the hollow cone of the partition B is
insured by the conical rotary movement of the arm 'A fixed at one end in the axes
of the two parts, S, S¹, that it connects through the ball r, in a rigid manner;
whilst the other end terminates in a small ball's turning freely in a bearing n.
This small balls that forms with the arm A an arrangement for conical develop-

page_text: ment, described in a vertical plane about the axis of rotation a circle of suitable
radius to ensure a proper contact which is increased by centrifugal force acting
on the masses S S and re-acting on the sphere s. On the shaft T carrying the
crank plate M, and passing through with slight friction, the bearing formed by the
casing K is keyed the fly-wheel Y. A ring F, of vulcanised fibre or other con-
venient matter forms a tight joint. Finally at-the outer extremity of the fixed
support serving as a bearing for the shaft T, and the fly-wheel Y, is arranged a
ball bearing that gives a very slight lateral resistance to rotation.
The central ball r, of the plate B, makes joint with the hollow central parts
of the top of the pistons S S. The rings insure the 'tightness of the con-
tact between the spherical parts of the pistons S S', and the spherical surfaces of
the casing.
The small projecting partitions el extend from the casing K K to the central
ball and are fixed to the plate B and each of these partitions enter into triangular
grooves (Figs. 2 and 3) in the face of the pistons S S operating them. Their
movement on the surfaces of the plate B, in, oscillating between the angular
sides o, o! (Fig. 2) about this partition; or better by the joint I, which gives à
joint of a larger area bearing against the said partitions or c that serve as
abutments for the fluid when it is a motor; gives to the pistons S S their
oscillating undulatory motion.

The two way cock, effecting the distribution of the motive fluid.is indicated..at
the foot of Figs. 5, 6, 7; the fluid enters by, the pipe, passes through the passages
and follows the course indicated by the arrows and exhausts by the lower outlet.
The two casings K K between which is fixed the plate Band surrounding
hermetically the pistons $ $ show on their respective sections at the left Fig. 6,
at the right Fig. 7. the inlet port and q and the exhaust ports. and q. of the
motive fluid, and the course followed as-follows:-
l
The admission of the fluid, entering by the pipe, is made at full pressure by the
right hand side passage Fig. 7, and this motive fluid produces an oscillation.of
the partition in the enlargement of the hollowed groove in the piston S. This
fluid abutting on, the right hand face of the said partition c, expands along, the
circular course indicated by the arrow. After a complete revolution of the ball s
to which, as well to the crank M, the movement of the piston is transmitted by
the arm A, the steam exhausts by the openings on the left of the partition c
and V passing from one casing to the other drawn at the left (Fig. 6) at the right
of the vertical plane passing through the centre of the ball r.
The motive fluid follows then the course of the arrows in the passage shown at
the right in the casing K¹ and enters by the port q, placed at the right of the
partition where it acts, on the piston, S following the circular course indicated
by the arrows and finally exhausts by the exhaust outlet. The ports and.q serve
therefore for the admission, and the ports and q serve for the exhaust.
...The action of the expansion of the gaseous fluid motor on the piston S¹, acts in
the same manner as the introduction at full pressure, of the said fluid on the
piston S and the effect is the same and the successive and simultaneous action. of
the two pistons causes a rotation of the shaft T and of the driving pulley and fly
wheel fixed on its outer end.
It can be seen that the mechanical work, produced on the face or truncated sur
face of the piston S, is added to that produced on the face, equally.. truncated; of
the piston S and that the shaft T collects the sum and transmits it to the driving
pulley.fixed on it, and presses by a face when rotating against the ball bearing.a
The motor described can also work as a motor with a liquid under..pressure;
it can also work as suction pump or forcing pump,. the special transmitting
mechanism.just described, driving or being driven.
For a hydraulic motor it is sufficient to connect. the liquid under pressure to
the inlet ports of the chambers formed by the casings or coverings K.K whilst the
exhaust takes place by the exhaust ports of. the said chambers...For the apparatus
to work as pump it is sufficient to rotate the shaft T by any suitable power, ori by

suction tube to the inlet ports of the casing K and K' and the delivering pipe to
the exhaust ports of the casing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
The mechanism forming a spheroidal motor consisting in the spheroidal
truncated pistons S S¹ mounted centrally on an arm A terminating at the other end
in a balls held between the two parts of a bearing n and working in the crank M.
The spherical parts of the pistons S S provided with partitions bearing against the
spherical surfaces of the casings KK work successively and symetrically, each in
its own working chamber formed by one of these casings and the fixed plate B,
with central ball and truncated sides, on each of which press the successive
generatrices of the pistons S S and carrying in a plane passing through the axis
of the arm A, the small separative projecting partitions e c which adjust them-
serves in the traingular recesses formed in each piston and serving as abutments
to the motive uids, which are admitted, distributed and exhausted by ports and
passages by means of a double-valve cock, as shown and described, or by means
of simple inlet and exhaust pipes for the motive fluid the whole constituting
a spheroidal motor for steam or air, adapted to work, either as a gas or hydraulic
pump, or motor by connecting the inlets and exhausts or delivery to the
corresponding ports of the chambers formed by the casings K K¹ and the plate B.
