I, GORDON DONALDSON PETERS, of Moorgate Works, Moorfields, in the City of
London, Manufacturer do hereby declare the nature of my invention for
IMPROVED MEANS FOR SUPPORTING AND PREVENTING THE RATTLING OF RAILWAY-
CARRIAGE AND SIMILAR WINDOW-SASHES" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improved means for supporting, and preventing the
rattling of, sliding window-sashes, such as are used in railway-carriages, tramway-
cars, and omnibuses, and is applicable to these and other windows in which there
is a vertically sliding sash that may require to be supported in different positions,
in a similar manner to that hereinafter described.
My said invention, when applied to a railway or other carriage, consists
essentially in constructing and arranging what is commonly known as the garnish-
rail (that is to say, the rail or bar across the door immediately below the opening
of the window) in such a manner that it will either support the sliding window-
sash or press against the same and prevent the rattling thereof which usually takes
place when the ordinary means for supporting the sash are employed.
For this purpose, I make the said garnish-rail movable upon hinges, pivots or
trunnions in such a manner that it will, by its own weight, or by the action of one
or more springs or counter-weights, either press against the sliding sash or fall
beneath the same, according to the position of the said sash as hereinafter
explained.
My improvements, as applied to a railway carriage, are illustrated in the
accompanying drawing, in which
Figure 1 is an elevation of the inner side of a railway-carriage-door, and
Figure 2 is a central vertical transverse section of the same.
a indicates the door, and b the window sash, which is fitted to slide up and
down in the ordinary manner in grooves al in the said door. These grooves are
made with parallel sides, and in these respect differ from those ordinarily employed,
which are made wider at the lower than at the upper end to permit the sash to be
moved outward in order that it may be supported in its closed position. c is the

page_text: garnish-rail, which is fitted with a roller c' and a stud c² for holding the window-
strap in the usual manner. The said garnish-rail is carried by the pivots or
trunnions e so that its weight acts to cause it to fall automatically beneath the
sash b, when the window is completely closed, or to press against the said sash,
when the latter is partially raised and the window-strap d is held by the stud c².
When the sash is thus supported by the strap, its weight tends, through the
medium of the said strap, to force the top of the garnish-rail against the said sash,
thus preventing any rattling thereof when the train is in motion. The said
garnish-rail, moreover, when in this position, prevents the entrance into the door-
framing of various kinds of rubbish or foreign bodies, many of which may become
very offensive.
When the sash is raised to completely close the window, and the
garnish-rail falls beneath the same, the said garnish-rail forms an efficient rest or
support for the sash, and, at the same time, not only prevents the entrance of
rubbish into the door-framing, but also prevents the passage through the same of
any draught, dust, or moisture, which is a source of considerable inconvenience
and discomfort to passengers in carriages provided with doors having the garnish-
rails constructed in the ordinary manner.
In cases where no garnish-rail is ordinarily used, I employ, as a substitute
therefor, a pivotted or hinged rail of wood or other suitable material.
Although the above description refers more especially to the windows of railway-
carriages, it is obvious that only very slight modifications would be required in
adapting my invention to other windows.
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 what
I claim is
The improved means substantially as above described for supporting, and
preventing the rattling of, window-sashes as above specified.
