Improved Means of Ventilating Railway Carriages, Tramcars, and
the like.
1 MAURICE PAUL HICKS of 311 Seven Sisters Road Woodberry Down in the
County of London Assistant in a Warehouse do hereby declare the nature of this
invention to be as follows:-
This invention relutes to improved means for ventilating railway carriages,
tramcars, etc., by, a continuous current of air caused to enter the same by the
velocity with which they are travelling.
In order that my invention may be more easily understood, I have shown the
same upon the accompanying sheet of drawings in which :-
:-
Figure 1. reprosonts a portion of door of a railway carriage outside, with the
ventilator attached, A being the ventilator. The arrow Z shows the direction in
which the train is travelling; the arrow B showing where the fresh air is forced in,
and C where the foul air is carried out.
Figure II. shows hor zontal section of the side of a compartment with ventilator
attached; A is the ventilator as in Fig. 1. The arrows B showing where the air
is forced in, and C where the foul air is carried out. Z is the direction in which
the train is travelling. D is a drawer without bottom or back, sliding in the
grooves E; the drawer D is represented open so as to allow the ventilation to take
place, but if the drawer D be closed, it will also close the ventilator A. outside the
compartment.
Figure III shows the drawer D on the inside of the compartment open as in
Fig. 1. E are the grooves in which it slides. The arrows B show where the air
is forced in, and C where the foul air is carried out. To close the ventilator push
the drawer D in, and_it_will_cover the entrance to the projecting part of the
ventilator A as shown in Fig. [L., and it will cover the grating through which the
air gets into the compartment.
Figure IIII. is the vertical section of ventilator. A is the ventilator, projecting
beyond the side of the compartment, which catches the air and carries it in the
direction of the arrow B into the compartment. D is the drawer. F is the side
of the compartment.

COMPLETE SPECIFICATION.
Improved Means of Ventilating Railway Carriages, Tramcars, and
the like.
I MAURICE PAUL HICKS of 311 Seven Sisters Road Woodberry Down in the
County of London Assistant in a Warehouse 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 relates to improved means for ventilating railway carriages,
tramcars, and the like, by a contínuous current of air caused to enter the same by
the velocity with which they are travelling.
In order that my invention may be more easily understood see drawings filed
with my Provisional Specification, in which :-
Figure 1. represents a portion of door of a railway carriage, outside, with the

page_text: ventilator attached, A. being the ventilator. The arrow Z. shows the direction in
which the train is travelling; the arrow B. showing where the fresh air is forced
n, and C. where the foul air is carried out.
Figure 11. shows horizontal section of the side of a compartment with ventilator
attached; A. is the ventilator as in Fig. I.
The arrows B. showing where the air is forced in, and C. where the foul air is
carried out. Z. is the direction in which the train is travelling. D. is a drawer
without bottom or back, sliding in the grooves E; the drawer D. is represented
open go as to allow the ventilation to take place, but if the drawer D. be closed, it
will also close the ventilator A. outside the compartment.
Figure III. shows the drawer D. on the inside of the compartment open as in
Fig. 11. E. are the grooves in which it slides.
The arrows B. show where the air is forced in, and C. where the foul air is
carried out. To close the ventilator, push the drawer D. in, and it will cover the
entrance to the projecting part of the ventilator A. as shown in Fig. 11, and it will
cover the grating through which the air gets into the compartment.
Figure III. is the vertical section of ventilator. A. is the ventilator, projecting
beyond the side of the compartment, which catches the air and carries it in the
direction of the arrow B. into the compartment. D. is the drawer. F. is the side
of the compartment.
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;
To have invented an improved method for ventilating railway carriages, tramcars,
and the like, by a continuous flow of air into the vehicles, caused to enter the
same by the velocity with which they are travelling, by this means driving all
foul air out.
