Improved Combined Apparatus for Facilitating the Raising and
Lowering of Railway Carriage and other Windows and the
like, and Excluding Draught and Dust from the Room or Space
to be Closed by such Window or the like.
We, JOHN CHARLES TAITE, and THOMAS WILLIAM CARLTON, both of 63, Queen
Victoria Street, in the City of London, Engineers, do hereby declare the nature of
this invention to be as follows:
11
This invention has reference to railway carriage and other windows and the like
arranged to slide or be lowered into doors, boxes, chambers or cases and has for object
to so construct and arrange a device that shall directly assist the raising and lowering
of a window and at the same time shall also serve as a draught or dust excluder.
According to this invention the window or the like rests upon a sliding bar or support
carried by one or more wires, bands, cords, or chains from a spring barrel or drum
(or barrels or drums), and arranged to facilitate the raising and lowering of the
window, the construction and arrangement of the said sliding bar or support being
such that when the window is raised to close it, the bar or support will rise and occupy
such a position below the window as to close the upper part (but not necessarily the
top) of the box chamber or case in which it slides and from which the window has
been raised, and prevent the passage of draught and dust therethrough.
In an arrangement of apparatus according to this invention the bar or support is
carried from two spring barrels or drums by metal strips or bands and is arranged to
slide in and be guided by the box, chamber or case which receives the window when
lowered. The spring barrels or drums are carried by and partly enclosed within the
garnish rail of the door, which is provided with an inwardly projecting piece or strip
that serves to limit the upward movement of the bar or support and assist it in
excluding draught and dust from the room or space closed by the window.

WO, JOHN CHARLES TAITE, and THOMAS WILLIAM CARLTON, both of 63 Queen
Victoria Street in the City of London, Engineers, 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 has reference to railway carriage and other windows and the like,
arranged to slide or be lowered into doors, boxes, chambers or cases and has for
object to provide and arrange a device that shall directly assist the raising and lowering
of a window and at the same time shall also serve as a draught or dust excluder.
According to this invention the window or the like rests upon a sliding bar or support
carried by one or more wires, bands, cords or chains from a spring barrel or drum
(or barrels or drums) and arranged to facilitate the raising and lowering of the
window, the construction and arrangement of the said sliding bar or support being
such that when the window is raised to close it, the bar or support will rise and
occupy such a position below the window as to close the upper part (but not necessarily,
the top) of the box, chamber or caso in which it slides and from which the window
has been raised, and prevent the passage of draught and dust there-through.
In an arrangement of apparatus according to this invention the bar or support is
carried from two spring barrels or drums by metal strips or bands and is arranged to
slide in and be guided by the box, chamber or case which receives the window when
lowered. The spring barrels or drums are carried by and partly enclosed within the
garnish rail of the door, which is provided with an inwardly projecting part or strip
that serves to limit the upward movement of the bar or support and assist it in
excluding draught and dust from the room or space closed by the window.
Referring to the accompanying sheet of drawings Fig. 1 shews a railway carriage
door (with the front panel removed) fitted with apparatus according to this invention
for raising and lowering the window and for excluding draught and dust.
Fig. 2 is a section to a larger scale through the garnish bar and other parts.
Fig. 3 is a detail view of one of the springs and pulleys, and shows the method of
its connexion to the draught excluder.
A is the bar or support sliding in the chamber B into which the window C is received
when lowered. The bar A is connected by two metal tapes D D with two pulleys
E E running on fixed spindles. Each pulley is connected to its spindle by a coiled
spring F which is wound up when the pulley is rotated in the direction to pay off the
tape D, and is relaxed when the pulley rotates in the opposite direction. The initial
tension of this spring can be adjusted by turning the spindle.
The pulleys E E run in cases or frames G G let into the garnish rail H. Each

page_text: metal tape D is fastened at one end to its pulley and at the other end to a bracket J
projecting from the face of the bar A, which is of sufficient depth to reach to the
mouth of the case, which it closes, when the window is raised to the full extent, by a
bead or moulding on its upper edge. With apparatus as described as will be evident
the spring or springs can be adjusted to suit the weight of the window or the like
and the raising of the window or the like will be facilitated owing to the support
afforded by the springs acting through the bar A which will also prevent the sudden
dropping of the window or the like thus likewise facilitating the lowering.
Having now particularly described and ascertained the nature of the said invention
and in what manner it is to be performed we declare that what we claim is :-
I. A dust and draught excluder for a railway carriage or other window or the like
comprising a sliding piece or bar moveable in the window box or case and carried by
one or more wires, bands, cords or chains from a spring barrel or drum (or barrels or
drums) in such a way that when the window or the like is raised or lowered the piece
or bar moves with it, substantially as described.
II. The improved combined apparatus for facilitating the raising and lowering of
railway carriage windows and the like, and for excluding draught and dust, constructed
arranged and operating substantially as described with reference to the drawings.
