Improved Means or Appliances for Preventing or Mitigating the
Rattling of Windows and the like, as well as Draught, and, if
desired, Giving an Alarm during the Opening of a Window or
the like.
I, HUBERT STUART MOORE, of 6, Kings Bench Walk, Temple, London E.C.
Student at Law, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to obviate or mitigate by simple means the rattling
of windows and the like, for examples shutters and doors (hereinafter included in
the expression "window") as well as draught and if desired giving an alarm should
a window be improperly opened.
To prevent rattling the window is in an automatic manner jammed against the
frame in which it slides by means of an eccentric device (or there may be more
than one) able to turn on a suitable pin or pivot. The eccentric device has formed
in it a recess of suitable shape into which as the window is being closed there enters
a suitably curved finger or projection that is attached to the window and which
during the completion of the closing movement causes the eccentric device to make
a partial rotation and to press the window against its frame.
A suitable stop arrests the eccentric device when the window is opened, and
retains the said device in a position such that the finger or projection before
mentioned will again engage with it when the window is being closed. When it is
desired that an alarm should be sounded on the opening of the window electrical
apparatus is arranged in connection with the said stop, and this may be so con-
structed that the re-closing of the window will not break the electric circuit the
current passing through which operates the alarm.
When the eccentric device is applied to a window that moves horizontally or
approximately so, suitable means such as a spring are employed to ensure the
return of the eccentric device into position against its stop.
When applying my invention to windows such as those of railway and other
carriages, I adapt it to prevent the rattling of windows when partly open. For
this purpose according to one plan the eccentric device or devices is or are suitably
connected with the button that holds the window strap, and which is pivoted or
otherwise made capable of movement in such a way that when through the strap
the weight of the window is cast upon the button, the consequent movement of the
button will through the intervening connection or connections, move the eccentric
device or devices into a position in which it or they will press against and prevent
or mitigate the rattling of the window.

Improved Means or Appliances for Preventing or Mitigating the
Rattling of Windows and the like, as well as Draught, and, if
desired, Giving an Alarm during the Opening of a Window or
the like.
I, HUBERT STUART Moore, of 6, Kings Bench Walk, Temple, London E.C.,
Student at Law, 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:-
The object of this invention is to obviate or mitigate by simple means the
rattling of windows and the like, for example sliding shutters and doors (hereinafter
included in the expression "window") as well as draught.
To prevent rattling, the window is in an automatic manner jammed against the
frame in which it slides by means of an eccentric device (or there may be more
than one) able to turn on a suitable pin or pivot. The eccentric device has
formed in it a recess of suitable shape into which as the window is being closed
there enters a suitably curved finger or projection that is attached to the window
and which during the completion of the closing movement causes the eccentric
device to make a partial rotation and to press the window against its frame.
A suitable stop arrests the eccentric device when the window is open, and
retains the said device in a position such that the finger or projection before
mentioned will again engage with it when the window is being closed.
If it be desired that an alarm should be sounded on the opening of the window
or when the window is negligently left open, electrical apparatus may be arranged
in connection with the said stop, and this may be so constructed that the re-closing
of the window will not break the electric circuit the current passing through which
operates the alarm.
When the eccentric device is applied to a window that slides horizontally or
approximately so, suitable means such as a spring are employed to ensure the
return of the eccentric device into position against its stop.
When applying my invention to windows such as those of railway and other
carriages, I adapt it to prevent the rattling of windows when partly open and when
closed. For this purpose the eccentric device or devices is or are suitably connected
with the button that holds the window strap, and which is pivoted or otherwise
made capable of movement in such a way that when through the strap the weight
of the window is cast upon the button, the consequent movement of the button will,
through the intervening connection or connections, move the eccentric device or
devices into a position in which it or they will press against and prevent or mitigate
the rattling of the window.
In the accompanying drawings,
Fig. 1 shews in side elevation an eccentric device applied in accordance with
my invention so as to be operated by the closing of an upper vertically sliding
sash.
Fig. 2 is a like view adapted to be operated by a lower vertically sliding
sash.
Fig. 3 shews part of a carriage window having my invention applied to it.
Fig. 4 is a sectional view at right angles to Fig. 3.
Referring to Figs. 1 and 2; A A' represent portions of the stationary frame of
the window; B a portion of the upper sliding part or sash of the window; B¹ a
portion of the lower sliding part or sash; C C₁ the respective eccentric devices;
C² C³ the recesses therein; C₁ C³ the pins studs or pivots on which the eccentric
devices are able to turn; D D¹ the plates that carry these pins studs or pivots, and
which are adapted to be readily secured to the window frame. E E¹ are the
peculiarly curved fingers or projections attached to the sliding sashes or parts of

page_text: the window. FF1 are the stops for limiting the movement of the eccentric
devices in one direction.
The pins studs or pivots C4 C³ can be formed with screw threads, and be each
furnished with a tightening device such as a nut or a pair of lock nuts by
adjusting which more or less resistance to turning can be imparted to the eccentric
device.
When the window is open the finger or projection E or E' causes the eccentric
device C or C¹ to turn and fall against the stop F or F as indicated in dotted lines
in which position the finger or projection will clear the eccentric device. As the
window is closed the finger or projection will re-enter the recess and turn the
eccentric device into the position shewn in full lines in the figures so that its part
of greatest radius will bear against the window as shewn in full lines thus jamming
the window securely in the frame.
If it be desired that an alarm should be given on the opening of the window or
on its being left open negligently the contact between the eccentric device C or C¹
and the stop For F' (which will in such a case be insulated from the plate D or D¹)
may be caused to complete an electric circuit as will be readily understood, a
suitable alarum being included in said circuit. Such an arrangement is indicated
in dotted lines in Fig. 1; H H¹ being conductors, I battery, and K an alarum such
as an electric bell.
In Figs. 3 and 4 A represents the window frame of a carriage, B the window and
C an eccentric device mounted in said frame and adapted when partly rotated by a
finger or projection E (which operates whilst the window is being pushed down into
the groove B2) to jam the said window in its frame. C" is another eccentric device
which is mounted in the window frame with its axis of rotation at right angles to
that of the eccentric device C. When on opening the window the finger or
projection E is removed from the recess in the eccentric device the eccentric device
is brought into position against the stop F by means of a small spiral spring C*.
L is a button or stud for the window strap; it is fixed to a lever M pivoted at M';
N is a link connecting the said lever to the eccentric device C". The button or
stud L is fixed to the free end of the lever and projects through a slot in the
frame A, the lever and link being as I prefer located inside the said frame.
A spring O tends to keep the button or stud L (when not supporting the window)
in a position in which the eccentric device C₁ will be clear of the window. The
parts being arranged as shewn, when the window strap is passed on to the button
or stud the latter is moved upward by the weight of the window and through the
medium of the lever and link causes the eccentric device C" to make a
partial rotation and to jam the window against the opposite side of the window
frame.
It will be seen that this arrangement enables the window to be secured against
rattling when partly open.
When I adapt my invention to a horizontally sliding window or door I use an
eccentric device and finger or projection similar and in analogous positions to those
shewn at C and E Figs. 3 and 4.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
-
1. For preventing or mitigating the rattling of windows and the like an eccentric
device adapted to turn about a pin or pivot attached to a part of the window frame
and to be operated through the moving part of the window the arrangement being
such that by movement imparted to it during the closing movement of the window
the said eccentric device will be caused substantially as hereinbefore described with
reference to Figs. 1, 2, 3 and 4 to assume a position in which it will jam the window
as here set forth so as to prevent or mitigate rattling and draught and during the
early part of the opening movement of the window the eccentric device will be
released and will assume a position in which whilst no longer pressing against the

page_text: window it will be ready to be acted upon as before during the closing movement of
the window for the purpose specified.
2. For a carriage window an eccentric device able to turn on a pin or pivot
applied to the window frame and so. arranged that when the window is fixed partly
open the eccentric device is operated by a pivotted lever connected with the button
or stud in such a manner that by the weight of the window the eccentric device is
caused to assume a position in which it will jam the window in its frame substantially
as described with reference to Figs. 3 and 4.
3. The combinations of parts constructed arranged and operating as shewn and
described with reference respectively to Figs. 1, 2, 3 and 4 of the drawings; for the
purposes specified.
