Improvements in Cylinder and Piston Motors.
We, ALFRED BOULIER, EUGÈNE BOULIER, and LEON FIVÉ, all of 41, Rue
Taitbout, Paris, in the Republic of France, do hereby declare the nature of this
invention to be as follows:-
According to this invention the parts transforming the reciprocating rectilinear
motion into continuous circular motion are placed inside the piston instead of
outside as heretofore.
By this arrangement motors may be constructed having the following
advantages:-
-
1. There is a considerable reduction in size which gives to the motor double
the power of an ordinary motor of the same volume.
2. The piston is better guided.
3. Friction is less and therefore wear is less.
4. In double acting motors no stuffing box is required.
Consequently motors constructed according to this invention are especially
suitable for motor cycles, cars, for ships, and other transport engines, in which
a motor of great power and of small size is required.
According to one arrangement the piston consists of a cylinder closed at both
ends and provided at each end with packing rings.
The body of the piston has in it two elongated slots placed opposite each other,
and giving access to the crank axle of the motor, which passes transversely across
the middle of the motor cylinder.
:
The piston reciprocates in the motor cylinder, and has in it a fixed pin connected
to the crank, by. a connecting rod.
In place of the body of the piston being a cylinder, it may consist of two heads
connected together by rods or otherwise."
According to another arrangement by which vibration is prevented, there are
two pistons of exactly the same weight having the same travel and the same speed,
but moving in opposite directions, the strains being therefore always equal so that
the reactions annul each other.
The pistons are provided with packing rings at one of their ends, whilst the
other end of each piston is prolonged beyond the crank shaft, and is slotted for the
passage of the shaft of the double crank of the motor.
The pistons reciprocate in opposite directions in the cylinder, fixed pins inside
the pistons being connected to the cranks by connecting rods.

We, ALFRED BOULIER, EUGENE BOULIER, and LEON FIVÉ, all of 41, Rue
Tait bout, Paris, in the Republic of France, 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:-
According to this invention the parts transforming the reciprocating rectilinear
motion into continuous circular motion are placed inside the piston instead of
outside as heretofore.
By this arrangement motors may be constructed having the following
advantages:-
1. There is a considerable reduction in size which gives to the motor double
the power of an ordinary motor of the same volume.
2. The piston is better guided.
3. Friction is less and therefore wear is less.
4. In double acting motors no stuffing box is required.
Consequently motors constructed according to this invention are especially
suitable for motor cycles, cars, for ships, and other transport engines in which
a motor of great power and of small size is required.
According to one arrangement shown in Figures 1 and 2 of the drawings,
Figure 1 being a longitudinal section through the axis of the motor and Figure 2
a transverse section on the line A A of Figure 1, the piston consists of a cylinder
closed at both ends and provided at each end with packing rings.
The body of the piston has in it two elongated slots 2 placed opposite each
other, and giving access to the crank axle 3 of the motor which passes transversely
across the middle of the motor cylinder.
The piston reciprocates in the motor cylinder 4 and bas in it a fixed pin 5
connected to the crank by a connecting rod 6.
It is not thought necessary to describe in detail these parts which are well
known; nor the other portions of the motor which may be of any asual con-
struction.
In place of the body of the piston being a cylinder it may consist of two heads
connected together by rods or otherwise.
According to another arrangement shown in Figures 3 and 4 by which vibration
is prevented there are two pistons of exactly the same weight having the same
travel and the same speed but moving in opposite directions, the strains being
therefore always equal so that the reactions annul each other.
Figure 3 is a longitudinal section through the axis of the motor and Figure 4
is a section on the line B B of Figure 3.
The pistons are provided with packing rings at one of their ends whilst the
other end of each piston is prolonged beyond the crank shaft, and is slotted at 8
for the passage of the shaft of the double crank 9 of the motor.
The pistons reciprocate in opposite directions in the cylinder 10, fixed pins 11, 11
inside the pistons being connected to the cranks by connecting rods 12, 12.
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:-
1. Placing the parts transforming the reciprocating rectilinear motion into

page_text: continuous circular motion inside the piston of any type of motor substantially
as described and illustrated in Figures 1 and 2 of the annexed drawings.
2. The arrangement of two similar pistons substantially as described and
shown in Figures 3 and 4 of the annexed drawings.
