Improvement in Window Fittings.
I, THOMAS KAY, of Moorfield, Stockport, Manufacturing Chemist, do hereby
declare the nature of this invention to be as follows:-
My invention has reference to the mode of holding in position or sustaining
sliding windows, and at the same time, to provide an effectual means of pre-
venting the rattle or vibration of the same. I take an ordinary frame in which
is fitted a window sash and I affix to the former a moveable shutter of wood
or metal upon hinges and so inclined that at any obtuse angle it shall fall upon
the window sash, or I may make the shutter to fall upon the window itself if
At the point of
the glass be strong enough to resist the necessary pressure.
contact between the outer edges of the shutter and the sash or window I affix
to the shutter pieces of india rubber or other material which resist friction.
To the shutter above described, I also attach a spring or by other means keep
it in position. When the window sash is raised, the shutter simultaneously
lifts, and allows the window to pass upwards. But on its release or on its descent,
the shutter presses against the window sash and the rubber by its resistance to
friction, assisted by the downward pressure of the window stays the descent and
confines it to the elevation desired. The shutter also prevents vibration by the
side pressure exercised.

THOMAS KAY, Moorfield, Stockport, Manufacturing Chemist, 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 and accompanying drawings:-
Figure 1 is a representation of the casing of a carriage window. I affix the
garnish rail A at a suitable angle to the glass frame B, by means of trunnion
side plates C (Figure 2) and screws at each side of the casement, and in these
side plates I place springs E (Figure 1) which exercise a downward pressure
of the garnish rail towards the glass frame B. On the under side of the garnish
rail A, and near each end, I insert a block or pad D of india rubber or other
suitable material. In the centre of the garnish rail A a plate is fixed F having
a rebate G, which coincides with the plafe H on the glass frame B. On pulling
the garnish rail A, it assumes an ever increasing angle, so that when almost

page_text: perpendicular the plate H on the glass frame falls away from the rebate G down
the run of the door. The plate on the garnish rail A forms an inclined
plane L with the glass frame B when in its normal position. Slightly to the
side of the plate on the garnish rail is affixed a pull K (Figs. 1 and 3). I
shall now proceed to explain the mode of action. When the pull K is brought
forward, lifting the garnish rail A, the glass frame pulls away and drops, but
on letting go the pull K the garnish rail presses downwards, and the rubber
blocks or pads D underneath come into contact with the frame B, and by this
means the glass frame can be arrested' and held in its descent at any place. To
raise the glass frame when it is down the run of the door, it is only necessary
to lift the frame by means of a strap. carried over the centre plate F. On
releasing the strap, the frame falls back upon the rubber blocks or pads which
are inclined at such an angle against it as to form a brake and hold it in position.
By lifting the glass frame up to the top, the plate H falls in position in the
garnish plate, the springs of which hold it tightly against the fence rail, so
as to effectually exclude wind and rain, and prevent vibration.
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
1. The insertion of blocks or pads of india rubber or other suitable material
in the garnish rails of railway or other carriage windows, for the purpose of
holding the windows in any required position and for the purpose of preventing
the vibration of the same.
2. The insertion of a plate in the centre of garnish rails of railway or other
carriage windows. The plate having an inclined plane and a rebate therein for
the purpose of guiding the glass frame in and out and securing it in position
when the window is closed.
3. The insertion of blocks or pads of india rubber or other suitable material
in the garnish rails of railway or other carriage windows arranged in com-
bination substantially as for the purposes herein before set forth and illustrated
in the drawings hereunto annexed.
