PROVISIONAL SPECIFICATION.
Improvements in the Cylinders of Vertical Motors for Motor
Vehicles.
I, AUGUSTE RENÉ LUCAS, of 64, Rue Amperé, Paris, in the Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in cylinder ends for vertical motors
which are cooled by contact with the atmosphere and which are more particularly
adapted for use on motor vehicles. The shape of such cylinder ends is devised
specially with the object of preventing the ovalisation of the cylinder and of
obviating the numerous disadvantages incident to such ovalisation.
The cylinder end as characterised by its special raised form, which on the one
hand enables the valve chest to be arranged higher so that the exhaust valve and
its conduit are completely above the cylinder proper, and on the other hand all
parts of the cylinder end and the whole of its conduits to be surrounded with
horizontal wings or ribs whereby uniform cooling at all points is effected.
The raising of the exhaust valve and its conduit possesses the double advantage
of preventing the heat arising from the exhaust pipe from heating the corre-
sponding wall of the cylinder and of leaving upon this wall a space free for the
provision of cooling wings; it follows from this that this portion of the cylinder
has no tendency to become more heated than the other portions and that the cool-
ing of the cylinder takes place in a perfectly uniform manner.
It should also be noticed that the form of the cylinder end is devised in such
a manner as to retain the superposition of the admission valve and exhaust
valve in one and the same box (which is very important in the case of motors
where cooling is effected by the atmosphere, in order to ensure the cooling of the
valve chest by the air drawn in) whilst at the same time enabling the whole of
the external surface of the cylinder end to be provided with wings which still
further increase this cooling effect, keeping it uniform at all points. All the
conduits of the cylinder end are thus surrounded by at least two wings tangen-
tial to such conduits. This arrangement is very important for ensuring efficient
cooling of the cylinder end, which is the part of the motor which has the greatest
tendency to become heated and to communicate its heat to the top of the cylinder.

page_text: the same is to be performed, to be particularly described and ascertained in
and by the following statement: -
This invention relates to improvements in cylinder ends for vertical motors
which are cooled by contact with the atmosphere and which are more particularly
adapted for use on motor vehicles. The shape of such cylinder ends is devised
specially with the object of preventing the ovalisation of the cylinder and of
obviating the numerous disadvantages incident to such ovalisation.
The improved cylinder end is represented in the accompanying drawing, in
which:-
Figure 1 is a vertical section through the cylinder end, and
Figure 2 is an external view of the same.
The cylinder end is characterised by its special raised form, which on the one
hand enables the valve chest to be arranged higher so that the exhaust valve E
and its conduit e are completely above the cylinder proper C, and on the other
hand to surround all parts of the cylinder end and the whole of its conduits with
horizontal wings or ribs a whereby uniform cooling at all points is effected.
The raising of the exhaust valve and its conduit possesses the double advantage
of preventing the heat arising from the exhaust pipe from heating the corre-
sponding wall of the cylinder and of leaving upon this wall a space free for the
provision of cooling wings w; it follows from this that this portion of the cylinder
has no tendency to become more heated than the other portions and that the cool-
ing of the cylinder takes place in a perfectly uniform manner.
It should also be noticed that the form of the cylinder end is devised in such
a manner as to retain the superposition of the admission valve A and exhaust
valve E in one and the same box (which is very important in the case of motors
where cooling is effected by the atmosphere, in order to ensure the cooling of the
valve chest by the air drawn in) whilst at the same time enabling the whole of
the external surface of the cylinder end to be provided with wings which still
further increase this cooling effect, keeping it uniform at all points. All the
conduits of the cylinder end are thus surrounded by at least two wings tangen-
tial to such conduits. This arrangement is very important for ensuring efficient
cooling of the cylinder end, which is the part of the motor which has the greatest
tendency to become heated and to communicate its heat to the top of the cylinder.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The special form and arrangement of cylinder end for vertical motors repre-
sented in the accompanying drawing, enabling an efficient and uniform distri-
bution of cooling wings upon the whole external surface of the cylinder and upon
the entire surface of the cylinder end itself, the principal result of which is to
permit of a rapid and uniform cooling of the whole of the upper portion of the
motor and consequently to avoid ovalisation of the cylinder.
