PROVISIONAL SPECIFICATION.
Improvements in Windows chiefly designed for Railway Carriages
and the like.
We, ALBERT RAUSCHER, Workshop Foreman, and JOHANN SCHILHAN, Heating-
house Foreman, both of the Railway Station, Székesfehérvar, in the Kingdom of
Hungary, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to a tightly closing window which when employed in
railway trains causes no shaking or noise when the train is in motion, whether
such window is closed or partially or completely open, that is to say lowered.
In a closed, that is to say, a completely raised, position the window-frame of a
single window is held by pressing under it the ledge, which is rotatably mounted
upon pivots.
If the rotatable ledge is caused to turn upon its pivot until it no longer sup-
ports the window this latter can be lowered without removing the window frame
from the plane which it occupied when the window was closed, that is to say, the
window may always be moved between two fixed parallel ledges which exactly fit
the window frame, and which may likewise be lined with cloth, plush or the
like for the purpose of further increasing the tightness of closing and preventing
rattle. Lateral play is also provided against in one of the following manners, viz.,
by the employment of felt or plush, the indented ledge, the ledge and plush, or
the metal ledge. Above, the window is tightly closed also by the use of cloth,
felt or plush.
The closing of the under part of the window is effected by the rotatable ledge
to the shape of which the lower edge of the window frame corresponds, it is like-
wise covered with plush, cloth or the like.
As the window frame has a very broad bearing upon the rotatable ledge, there
will still be sufficient tightness of closing even should the window frame become
distorted.
The rotatable ledge turns as already stated, upon the pins or pivots provided at
each end which pins rest in bearings.
A second pin of the rotatable ledge which enters the bearing through a slot in
the form of an arc of a circle, is constantly pressed against the window frame by
means of the spring.
When the window is completely raised, the spring therefore presses the ledge
beneath the frame. When the window occupies intermediate positions however,
the noses or projections on the ledge are pressed into the notches formed in the
side of the window frame by the spring by which means the window may be
firmly held at various heights.
This device serves for single windows and for the inner sash of double windows.
In double windows a lever is employed to open the outer window, this lever is
capable of vertical displacement in the mullion of the window between the two
sashes and with it engages a pin upon the rotatable ledge which is similar to the
ונםימ

ledge may be caused to turn upon the pins as soon as the said lever becomes acces-
sible by the opening of the inner window.

Improvements in Windows chiefly designed for Railway Carriages
and the like.
We, ALBERT RAUSCHER, Workshop Foreman, and JOHANN SCHILHAN, Heating-
house Foreman, both of the Railway Station, Székesfehérvar, in the Kingdom of
Hungary, 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 relates to a tightly closing window which when employed in
railway trains causes no shaking or noise when the train is in motion, whether
such window is closed or partially or completely open, that is to say lowered.
The invention is illustrated in the accompanying drawing in which
Figure 1 is a longitudinal section through a single window.
Figure 2 is a longitudinal section through a double window.
Figures 3-7 are sectional views of various constructional forms of our invention.
Figure 8 shews the lever for opening the outer window of a double window, and
Figure 9 represents a portion of the movable ledge with its nose or projection
which serves to hold the window at the different heights at which it is placed.
In a closed, that is to say a completely raised position the window frame A of
a single window is held by pressing under it the ledge B, which is rotatably
mounted upon pivots b, as shewn in Figure 1.
If the rotatable ledge B is caused to turn upon its pivot b by means of the
handle C until it is disengaged from the window A, the latter can be lowered
without removing the window frame from the plane which it occupied when the
window was closed, that is to say, the window may always be moved between two
fixed parallel ledges which exactly fit the window frame, and which may likewise
be lined with cloth, plush or the like as shown at & Figures 3-7 for the purpose
of further increasing the tightness of closing and preventing rattling.
Lateral
play is also provided against in one of the following manners, viz.: by the em-
ployment of felt or plush as shewn in Figure 3, the indented ledge D, shewn in
Figure 4, the ledge and plush in Figure 5, or the metal ledge T shewn in
Figures 6 and 7. The window is tightly closed above also by the use of cloth, felt
or plush (see Figures 1 and 2).
The closing of the under part of the window is effected by the rotatable
ledge B, to the shape of which the lower edge of the window frame corresponds;
it is likewise covered with plush, cloth or the like as indicated by d³ in Figures 1
and 2.
As the window frame has a very broad bearing upon the rotatable ledge, there
will still be sufficient tightness of closing even should the window frame become
distorted.
The rotatable ledge B turns, as already stated, upon the pins or pivots 6 pro-
vided at each end (Figures 1 2, 8 and 9) which pins rest in bearings S (Figures 1,
2. and 8). A second pin Z of the rotatable ledge B (Figures 1, 2, 8 and 9) which

page_text: enters the bearing S through a slot in the form of an arc of a circle, is con-
stantly pressed against the window frame by means of the spring F (Figures 1, 2
and 8).
When the window is completely raised, the spring F therefore presses the ledge
beneath the frame A. When the window occupies intermediate positions however,
the noses or projections n on the ledge B (one of which is shewn in Figures 1, 2
and 9) are pressed into the notches k formed in the sides of the window frame
(Figures 1 and 2) by the spring F, by which means the window may be firmly
held at various heights.
This device serves for single windows and for the inner sash of double windows.
In double windows a lever H (Figures 2 and 8) is employed to open the outer
window, this lever is capable of vertical displacement in the mullion of the
window between the two sashes and with it engages a pin 71 upon the rotatable
ledge B which is similar to the ledge B of the inner sash of the window. By
depressing the slide or lever H. the ledge B may he caused to turn upon the
pins as soon as the said lever becomes accessible by the opening of the inner
window.
Having now particularly described and ascertained the nature of our said
invention. and in what manner the same is to be performed, we declare that what
we claim is:
1. A sash window with a ledge (B) capable of being pushed beneath it, which
ledge turns upon pins (b) working in bearings (S) at each end and is provided
with pins (2) which engage in the bearings and remain there under the action
of springs (F) which have a tendency to press the ledge either against or beneath
the window, in such manner that by drawing back the ledge by means of a
handle (C) the window is left free in order that it may be pushed down and
opened without interfering with its vertical guiding, noses or projections (n) being
provided upon the ledge (B) for entering notches (k) in the window frame in order
to firmly hold the window at various intermediate heights.
2. A double window in which the inner window is arranged in accordance with
Claim 1, and the outer window provided with a ledge (B) capable of being pushed
beneath it and which is similar to the ledge (B) of the inner window but is
operated by means of pins (2³) engaging in the bearings (S) and with a slide or
lever (H) working vertically and arranged in the mullion of the window, in such
a manner that upon depressing the lever the ledge (B) is rotated so as to release
the outer window and leave it free to slide down without leaving its vertical
guides.
3. In windows in accordance with Claims 1 and 2, packing (Œ, ď³, №³) of felt,
cloth or plush on the edges of the window frame in order both to ensure tight
fitting of the window and to prevent it from rattling.
