Improvements in Devices for Preventing the Rattling and Shaking
of Sliding Window Sashes.
We, WILLIAM BALMER ATKIN, of 99, Tiber Street, Lodge Lane, Liverpool, in
the County of Lancaster, Joiner, and WILLIAM ARTHUR EVANS, of 99, Tiber
Street aforesaid, Engineer, do hereby declare the nature of this invention to be
as follows:-
1
This invention relates to devices for preventing rattling and shaking of sliding
window sashes, and has for its object certain improvements which will now be
described.
In carrying our invention into effect, we secure to the side of each window
sash near its meeting rail a plate, having a wedge shaped projection, and in close
proximity thereto we secure to the window frame a plate with a stationary abut-
ment projecting therefrom. These plates are so arranged that when the sashes
are closed the wedge shaped projections come in contact with the stationary
abutments and press the sashes forcibly against the parting bead, thus jamming
them and preventing any possibility of rattling. When however the sashes are
raised the plates carrying the wedge shaped projections instantly move away
from the stationary abutments, thus releasing the sashes and enabling them to
be moved freely. Similar plates with wedge shaped projections are provided at
the bottom and top of the sash, which engage in plates having holes made in
them, against one side of which the wedge shaped projections press when the
sashes are closed, thus producing the same result as the projecting abutments
aforesaid.
It is obvious that the invention besides preventing rattling also prevents
draught. The invention may be applied to almost any kind of sliding sashes, not
only where there are two sashes with meeting rails, but to single sliding sashea
such as are used in vehicles. It is obvious moreover that the plates with the
wedge shaped projections and the stationary abutments may be fixed respectively
on the sashes and on the window frame or vice versa whichever is preferred, one
arrangement answering almost equally well as the other. When the plates with
the wedge shaped projections are fixed on a sloping sill, the wedge shaped pro-
jection is formed accordingly so as to allow for the slope.

We, WILLIAM BALMER ATKIN, of 99, Tiber Street, Lodge Lane, Liverpool, in
the County of Lancaster, Joiner, and WILLIAM ARTHUR EVANS, of 99, Tiber
Street aforesaid, Engineer, 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 devices for preventing rattling and shaking of window
sashes, and has for its object certain improvements which will be understood
from the following description, reference being had to the accompanying draw-
ings, in which,
Figure 1 is a front view of a part of the upper sash (open) and frame of a
window.
Figure 2 a similar elevation showing a part of the two sashes at their meeting
rails (closed).
Figure 3 an elevation showing a part of the lower window sash partly open,
Figure 4 detail views of the stationary abutment and wedge shaped projection,
Figure 5 detail views of the plates H and J,
Figure 6 a cross section showing the two sashes at their meeting rails.
Referring to these figures, we secure to the side of each window sash near its
meeting rail A a plate B, having a wedge shaped projection C, and in close
proximity thereto we secure to the window frame E a plate D with a stationary
abutment projecting therefrom. These plates are so arranged that when the
sashes are closed the wedge shaped projections C come in contact with the
stationary abutments F and press the sashes forcibly against the parting bead G,
thus jamming them and preventing any possibility of rattling. When however
the sashes are raised the plates carrying the wedge shaped projections C instantly
move away from the stationary abutments F thus releasing the sashes and
enabling them to be moved freely. Similar plates H with wedge shaped 'pro-
jections I are provided at the bottom and top of the sash, which engage in
plates J having holes K made in them, against one side of which the wedge
shaped projections press when the sashes are closed, thus producing the same
result as the projecting abutments aforesaid. L is the glass of the sashes and M
the cords for the counterweights.
It is obvious that the invention besides preventing rattling, also prevents
draught. The invention may be applied to almost any kind of sliding sashes,
not only where there are two sashes with meeting rails, but to single sliding
sashes such as are used in vehicles. It is obvious moreover that the plates with
the wedge shaped projections and the stationary abutments may be fixed respec-
tively on the sashes and on the window frame or vice versa whichever is preferred,
one arrangement answering almost equally well as the other. When the plates
with the wedge shaped projections are fixed on a sloping sill, the wedge shaped
projection is formed accordingly so as to allow for the slope.
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. The improvements in devices for preventing the rattling and shaking of
sliding window sashes, which consists in securing to each window sash at the
sides a wedge shaped projection, and in close proximity thereto on the window

page_text: frame a stationary abutment projecting therefrom, said wedge and abutment
being so arranged relatively, that when the sashes are closed the wedge shaped
projection will come into contact with the stationary abutment and press the
sashes forcibly against the parting bead, while when the sashes are raised, the
wedges instantly move away from the stationary abutments, thus releasing the
sashes, and enabling them to be moved freely, substantially as described.
2. In devices for preventing rattling and shaking of sliding window sashes,
plates such as H having wedge shaped projections J located at the bottom and
top of sash, and plates having holes K against one side of which the wedge
shaped projections press when the sashes are closed, thus forcibly pressing the
sashes against the parting bead and preventing any possibility of rattling, sub-
stantially as described.
3. The devices for preventing rattling and shaking of sliding window sashes,
substantially as set forth.
