We, HOWARD BUSBY Fox, of Oxton, in the County of Chester, and
RICHARD LLOYD GURDEN, of Birkenhead, also in the County of Chester,
do hereby declare the nature of the said Invention for "AN IMPROVED
GUARD FOR PROTECTING THE WINDOWS AND DOORS OF RAILWAY AND OTHER
CARRIAGES AND MOVING STRUCTURES FROM DRAUGHT AND DUST," to be as
follows:-
'
The nature of our Invention consists in providing the windows and
doors of railway and other carriages and moving structures with a guard
for protecting the interiors of such carriages or moving structures from
the entry of draught and dust.
To enable our Invention to be understood we will describe its
application to an ordinary railway carriage, and it will be seen that the
guard can also be applied to any other moving structure. The guard
consists of a frame containing a glass plate, or wire guaze, or other
suitable material. The frame is made in length rather more than the

ordinary railway carriages about six or eight inches in width. The
frame or guard is fitted with sockets or staples with square apertures,
which take on to square pins fitted rather in front of the window. or
aperture to be protected. The guard when placed in position is set at
an angle to the side of the railway carriage, and is held in position by
the square pins, a quadrant, angle pieces, or by any suitable mechanical
The guard thus projects from the side of the window frame and
slightly overlaps the window or aperture at such an angle that when the
carriages are in motion the wind, draught, and accompanying dust
striking the guard is diverted from entering the carriage and annoying
the passengers facing the line of motion, and thus enabling the windows
to be kept open and the carriage at the same time free from draught.
The guards are so arranged that they can be moved by the porters and
affixed to whichever end of the carriage is in front.
means.
The before-going method explains how our Invention can be applied to
the carriages now in use, but in the case of new carriages we prefer that
the wind guards should be fitted in the door frame, and so made as to
slide up the frame on each side as required. To effect this object we
form a gutter or slide down the side of the window frame and door.
The guard is fitted with projecting lugs, which take into the groove or
gutter and hold the guard in position. Thus arranged the passenger
can raise the guard from the interior of the carriage, and when lifted
sufficiently the guard turns out to the required angle, and is held in
position either by dropping into a groove cut in the door frame at the
required angle, thus holding the guard in position, or the same object
may be attained by fitting the lower edge of the guard with a small
jointed quadrant.
Any suitable mechanical means may be used for affixing and holding
the guard in position, our Invention consisting in diverting the direction
of the wind and dust by means of angle pieces or guards, as before
described, fitted in front of the windows and doors of railway carriages
· and other moving structures.
