Improved Means or Apparatus for Supporting Sliding Windows,
such as those of Railway Carriages, Excluding Draught, Dust,
and Rain.
I, HENRY ALFRED IVATT of St. John's, Island Bridge, Dublin, Ireland, Locomotive
Engineer. Great Southern & Western Railway, do hereby declare the nature of
this invention to be as follows:-
:-
My invention has reference to means or apparatus for supporting sliding windows
such as those of railway carriages excluding draught dust and rain, and the arrange-
ment is such as will also prevent rattling of the window.
I provide a hinged garnish rail or flap which by means of a spring or springs is
kept normally vertical or approximately so. It is provided with what I call a
weathering strip or projection which when the window is closed and supported by the
garnish rail or flap takes over the fence rail and serves to exclude draught, dust, and
rain. The weathering strip can be made to serve also as a means of engagement
between the garnish rail or flap and the window supporting the latter at different
elevations. Or the garnish rail or flap is provided with projections to engage with
slots or holes in plates at the respective sides of the sliding window sash.
If the sash be closed and the garnish rail or flap pushed outward (i.e., towards the
outer side of the door) the sash being lowered on to the garnish rail or flap will be
supported. If the sash be then slightly raised, the garnish rail or flap will be
automatically returned to the vertical attitude in which it will not bear against the
sash. If the sash be partially lowered, and during the lowering thereof the garnish
rail or flap be pressed towards the sash, the weathering strip will engage with
suitable parts on the window, or where projections are provided the projections will
engage with one or other of the sets of slots, or holes, so that the sash will be arrested
and held in the position into which it has been lowered, that is, more or less open

page_text: according to the particular hole or holes with which the projections of the garnish rail
or flap may have engaged. If, now, the sash be raised, the garnish rail or flap will
immediately resume a vertical attitude clear of the sash.
The window may be fitted with a strap for raising and lowering it, or not; if so
provided, the weathering strip must be formed to suit.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Supporting Sliding Windows,
such as those of Railway Carriages, Excluding Draught, Dust,
and Rain.
I HENRY ALFRED IVATT of St. John's, Island Bridge, Dublin, Ireland, Locomotive
Engineer Great Southern & Western Railway 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 :-
My invention has reference to means or apparatus for supporting sliding windows
such as those of railway carriages excluding draught, dust, and rain, and the arrange-
ment is such as will also prevent rattling of the window.
I provide a hinged garnish rail or flap which by means of a spring or springs is
kept normally vertical or approximately so. It is provided with what I call a
weathering strip or projection, which, when the window is closed and supported by
the garnish rail or flap takes over the fence rail and serves to exclude draught, dust,
and rain. The weathering strip can be made to serve also as a means of engagement
between the garnish rail or flap and the window supporting the latter at different
elevations. Or the garnish rail or flap is provided with projections to engage with
stops or holes in plates at the respective sides of the sliding window sash.
If the sash be closed and the garnish rail or flap pushed outward (i.e. towards the
outer side of the door) the sash being lowered on to the garnish rail or flap will be
supported. If the sash be then slightly raised the garnish rail or flap will be auto-
matically returned to the vertical attitude in which it will not bear against the sash.
If the sush be partially lowered, and during the lowering thereof the garnish rail or
flap be pressed towards the sash, the weathering strip will engage with suitable parts
on the window, or where projections are provided, the projections will engage with

page_text: one or other of the sets of slots or holes, so that the sash will be arrested and held in
the position into which it has been lowered, that is, more or less open according to
the particular hole or holes with which the projections of the garnish rail or flap may
have engaged. If, now, the sash be raised, the garnish rail or flap will immediately
resume a vertical attitude clear of the sash.
The window may be fitted with a strap for raising and lowering it, or not; if so
provided, the weathering strip must be formed to suit.
In the accompanying sheet of drawings Fig. 1 shews in elevation part of a railway
carriage door with my invention applied to it.
Fig. 2 is a vertical section on the line A, B, of Fig. 1 showing the window closed
and supported by the garnish rail.
Fig. 3 is a vertical section on the line C, D, of Fig. 1 shewing the window supported
partly open.
Fig. 4 is a similar view to Fig. 2 shewing the window wide open.
Figs. 5 and 6 are detail views.
1 is a garnish rail or flap hinged at 2 and normally held in the vertical or
approximately vertical position shewn in Fig. 4 by means of one or more springs 3.
4 is a weathering strip secured to and extending along the upper part of the garnish
rail or flap the overhanging or projecting portion 5 is adapted to fit over a fence
rail 6 and to form a close joint therewith to exclude draught, dust and rain, after the
window 7 has been closed by fully raising it, then pushing the garnish rail or flap
outward, and lowering the window on to it as shewn in Fig. 2.
The weathering strip 4 is provided with a pair of projections 8 adapted to enter
one or other of the pairs of holes or recesses 9 at the sides of the window sash 10.
In the example shewn these holes or recesses extend through plates 11 that are
secured to the window sash, and into recesses formed in the sash itself as shewn. By
raising or lowering the said window sash and pressing the garnish rail or flap against
it, in opposition to the action of the spring or springs 3, the projections
caused to enter one or other of the pairs of holes or recesses 9 and the window
will then be held partly open as shown in Fig. 3.
may be
Although the projections whereby the garnish rail is made to engage with and
support the window are shewn as forming part of the weathering strip they might
be separate therefrom-also such projections might be dispensed with if racks or
horizontal notches were provided on or in the window frame at suitable heights with
which the edge of the weathering strip might engage.
The arrangement of the apparatus is such that assuming that the garnish rail is
supporting the window, if now the window be raised slightly the said rail will
automatically assume the vertical or approximately vertical attitude shewn in Fig. 4
in which position it leaves the window free to be raised or lowered as desired.
To prevent the garnish rail or flap 1 being forced too far inward and away from
the window by the action of the spring or springs 3, a pin or projection 12 (Figs. 5
and 6) is fixed to one of the side frames of the window and arranged to extend into a
slot or recess 13 formed at one end of the garnish rail or flap and closed at its outer
end by a plate 14.
It will be evident that means or apparatus constructed according to this invention
for supporting sliding windows and excluding draught, dust and rain, may be applied
to windows other than those of railway carriages; thus it may be applied to the
sliding windows of tramcars and steamboats.
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 I'do not
claim broadly the nse of a hinged or pivotted garnish rail or flap for supporting a
window when closed, or the use of a bar or support provided with means for holding
a window partly open, but what I claim is :-
1. In apparatus for supporting sliding windows such as those of railway carriages,
the use of a hinged or pivotted garnish rail or flap that is normally kept vertical or
approximately vertical by a spring or springs and is provided with a weathering strip

page_text: or projection, the arrangement being such that if the window be closed, the garnish
rail or flap pushed outward and caused to support the window, the said garnish rail or
flap will at the same time close the box or chamber out of which the window has been
raised and the weathering strip or projection will take over a fence rail thereby
excluding draught, dust and rain, and if when supported by the garnish rail or flap
the window be raised clear of it, the garnish rail or flap will be automatically
returned to the vertical attitude leaving the window free, substantially as heroinabove
described.
2. Providing the garnish rail or flap, or the weathering strip or projection referred
to in the preceding claim with means for engagement with the sliding window for the
purpose of supporting the same in a partly opened or closed position, substantially as
hereinabove described.
3. My improved apparatus for supporting sliding windows and excluding draught,
dust and rain, constructed, arranged and operating substantially as hereinabove
described and shewn in the drawings annexed.
Dated this 9th day of October 1888.
