page_text: LETTERS PATENT to Charles Thomas Marzetti, of John Street, Crutched Friars,
in the City of London, for an Invention of "NEW OR IMPROVED MEANS OF
PREVENTING DRAUGHTS OF AIR OR DUST FROM ENTERING THE WINDOWS,
DOORS, OR VENTILATORS OF RAILWAY AND OTHER CARRIAGES, APPLICABLE
ALSO TO OTHER WINDOWS, DOORS, OR VENTILATORS."
PROVISIONAL SPECIFICATION left by the said Charles Thomas Marzetti at
the Office of the Commissioners of Patents on the 9th March 1880.
CHARLES THOMAS MARZETTI, of John Street, Crutched Friars, in the City of
London. "NEW OR IMPROVED MEANS OF PREVENTING DRAUGHTS OF AIR OR DUST
FROM ENTERING THE WINDOWS, DOORS, OR VENTILATORS OF RAILWAY AND OTHER
CARRIAGES, APPLICABLE ALSO TO OTHER WINDOWS, DOORS, OR VENTILATORS."
The object of my Invention is to prevent the entrance of draughts of air or dust
through the open windows, doors, or ventilators of railway and other carriages, in
such manner that passengers may travel with the windows either partially or
entirely open, without incurring the danger and annoyance of the cutting draughts
of air or dust which enter through the windows when the carriages are in motion.
At the same time my Invention does not prevent the free circulation of air through
the carriage. It may also be applied in some cases to the windows, doors, or
ventilators of houses or otherwise.
The Invention consists of a kind of wind-guard deflector or arrester fixed upon
the stile or near the edge or side of the window, door, or ventilator, extending from
top to bottom thereof, and projecting obliquely inwards from the said.stile, edge, or-
side of the window, door, or ventilator. This wind-guard, deflector, or arrester is
by preference made of a trough like section in sheet metal or other suitable
material, and with one or more curved or straight deflecting plates or tongue pieces
projecting therein, the whole being so arranged that the draught or current of air
or dust impinges upon the interior of the said trough and against the deflecting
plates or tongue pieces therein, and is arrested, being broken up, dispersed, or
deflected, and prevented, more or less, from entering the carriage, or from impinging
upon a person sitting in the line of such draught or dust.

CHARLES THOMAS MARZETTI, of John Street, Crutched Friars, in the City of
London. NEW OR IMPROVED MEANS OF PREVENTING DRAUGHTS OF AIR OR DUST
FROM ENTERING THE WINDOWS, DOORS, OR VENTILATORS OF RAILWAY AND OTHER
CARRIAGES, APPLICABLE ALSO TO OTHER WINDOWS, DOORS OR VENTILATORS."
The principal object of my Invention is to prevent, more or less, the entrance of
draughts of air or dust through the open windows, doors, or ventilators of railway
and other carriages, in such manner that passengers may travel with the windows
or ventilators either partially or entirely open without incurring the danger and
annoyance of the cutting draughts of air or dust, which at present enter through
the windows and ventilators when the carriages are in motion. At the same time
my Invention does not prevent the free circulation of air through the carriage. It
may also be applied in some cases to the windows, doors, or ventilators of houses or
otherwise.
In the Drawings, Figure 1 represents a vertical section of so much of a railway
carriage door as is necessary to illustrate the application of my Invention to the
window thereof; Figure 2, an elevation of the same seen from the inside of a
carriage; Figure 3, a cross section, and Figure 4, a partial elevation of what I
hereinafter designate a wind-guard, deflector, arrester, or excluder.
The Invention consists of a kind of wind guard deflector, arrester, or excluder A
(see Figures 1 and 2 of the Drawings) fixed upon the stile B or near the edge or
side of the window, door, ventilator, or other opening C extending from top to
bottom thereof, and projecting obliquely inwards from the said stile edge or side of
the said window, door, ventilator, or other opening.
This wind guard, deflector, arrester, or excluder A is by preference made of a
trough like section in sheet metal or other suitable material, as shewn to about
full size in Figures 3 and 4, and with one or more curved or straight deflecting
plates or tongue pieces D projecting therein, the whole being secured to the stile or
side of the window or other opening with the box like space D¹ left between the
said wind-guard, deflector, arrester, or excluder and the stile, as shewn, the arrange-
ment being such that the draught or current of air or dust, which impinges some-
what in the direction of the arrow upon the interior of the said trough, and against
the deflector, plate, or tongue piece D therein, is arrested, broken up, dispersed, or
deflected, and prevented, more or less, from entering the carriage, or from impinging
upon a person sitting in the line of such draught or dust, the dust being retained
in the box like space D¹.
The wind-guard, deflector, arrester, or excluder A may in some cases be provided
with end pieces E, E, for stiffening the same, and such end pieces may be so shaped
as to present flanges or other projections by which the same may be secured by
screws or otherwise at top or bottom, or both.
The Figures 1 and 2 illustrate the application of the wind-guard, deflector,
arrester, or excluder to the window in the door of a railway carriage; its application
to other openings, whether in other vehicles or in rooms, chambers, or houses, may
obviously be effected in a similar manner, the form of the wind-guard, deflector,
arrester, or excluder and the manner of fixing the same, being varied according to
circumstances.
Having now described the nature of my said Invention and the manner in which
the same is to or may be carried into effect, I would have it understood that what
I claim as my Invention is,-
The wind-guard, deflector, arrester, or excluder constructed, arranged, and applied

page_text: to the windows, ventilators, or other openings in railway or other carriages, or in
rooms, chambers, or houses, substantially as hereinbefore described and illustrated
in the Drawings, and for the purposes hereinbefore set forth.
In witness whereof, I, the said Charles Thomas Marzetti, have hereunto set
my hand and seal, this Eighth day of September, in the year of our Lord
One thousand eight hundred and eighty.
