Complete Specification Left, 21st Aug., 1897-Accepted, 2nd Oct., 1897
I, HIPPOLYTE LEPAPE of 23, Rue Montaigne, Paris, France, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to dispense with water in the cooling of petroleum
motors of comparatively small power employed in auto-cars. For this purpose the
motive cylinder is furnished on the outside with longitudinal partitions radiating
around the axle, and surrounded with a cylindrical jacket the whole cast with the
partitions of the motor cylinder. In this way air chambers in the direction of the
generatrices are obtained, having an opening at the front and receiving the air-
current produced by the movement of the auto-car. The hinder part of the
cylinder is closed by a box terminating in a discharge-pipe.
All the chambers, therefore lead into this box.
The intermittent escape from the motor takes place in the discharge pipe of the
said box, thus considerably increasing the natural draught, a result produced from
this fact that an intermittent injection into a tube produces a discharge of the
gaseous mass fifty times greater than the discharge produced by an uninterrupted
injection on the same volume.
The intermittent current corresponds to a depression of 30 centimetres of water.
Dated this Fourteenth day of December 1896.

1, HIPPOLYTE LEPAPE of 23, Rue Montaigne, Paris, France, Civil Engineer, 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 this invention is to dispense with water in the cooling of petroleum
motors of comparatively small power employed in auto-cars.
For this purpose the motive cylinder is furnished on the outside with longi-
tudinal partitions radiating around the axle and surrounded with a cylindrical
jacket, the whole cast with the partitions of the motive cylinder.
In this way air chambers in the direction of the generatrices are obtained,
having an opening at the front and receiving the air current produced by the move-
ment of the auto-car. The hinder part of the cylinder is closed by a box
terminating in a discharge pipe.

The intermittent escape from the motor takes place in the discharge pipe of the
said box thus considerably increasing the natural draught a result produced by
this fact that an intermittent injection into a tube produces a discharge of the
gaseous mass fifty times greater than the discharge produced by an uninterrupted
injection on the same volume.
The intermittent current corresponds therefore to a depression of 30 centimetres
of water.
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:
1st. The air-chambers situated around the motive cylinder and formed by
radiating partitions and a cast iron jacket, those air chambers being open in the
direction of the movement. of the vehicle.
2nd. The increase of this air-current produced by a forced draught through a tube
forming a continuation of the air-chambers by means of the intermittent escape
from the motor.
