Improvements in Apparatus for Suspending and Preventing the
Rattling of Window Sashes or Frames and Blinds, More Espe-
cially those of Railway, Tram, and other Cars and Vehicles.
I, NEWNHAM BROWNE, of 73, Cheapside, in the City of London, Fellow of the
Institute of Patent Agents do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SUSPENDING AND PREVENTING THE RATTLING
OF WINDOW SASHES OR FRAMES AND BLINDS MORE ESPECIALLY THOSE OF RAILWAY,
TRAM AND OTHER CARS AND VEHICLES," which Invention has been communicated
to me from abroad by James Seed, of Southbrook, in the Provincial District of
Canterbury, in the Colony of New Zealand, Manufacturer, and Henry Abel Flatman,
of Southbrook, aforesaid, Engineer, to be as follows
The Invention relates to an apparatus intended to be fixed to the movable frames or
sashes of the windows of Railway Carriages, Tram Cars, and the like, and to the
frames of the blinds and shutters with which such windows are fitted, and consists of
an arrangement of parts by which the sash is held firmly against the fixed frame in
such manner as to prevent its rattling.
It will be obvious that this Invention adınits of considerable variation in the shape
and arrangement of its various parts and I therefore proceed to describe the form
which has been found most advantageous but without restricting the Invention to the
exact construction set forth.
According to this Invention there is fastened to the side and top edges of the
window sash, blind frame, or the like a bracket in the front edge of which is a groove
in which works a spring which is attached to the bracket and which serves to force
forward a tongue against the window frame thus cramping one side of the sash
with the frame the whole length of the sash, and the other side, the whole length of
the tongue.

page_text: For the purpose of releasing the sash and allowing it to move freely up and down
a lever is connected with the tongue by a pin or other suitable joint and pivoted in
the groove of the bracket and to the long end of this lover is attached a connecting
rod which passes along the inside of the top of the bracket and is turned at right
angles through a curved slot in the same, and is connected to a raising handle which
is by preference pivoted on a boss on the bracket.
Thus on lifting or lowering the sashes, by the movement of the handle, motion is
given to the lever, and the tongue is drawn back into the groove in the bracket, but
on the handle being released the tongue is repelled by the spring and the sash
effectually suspended and rattling prevented.
A cap covers the top of the bracket and prevents the entrance of dust and rain and
may be dovetailed to the bracket.
The handle by which the sash is released may be fixed to work in any position
along the top of the sash by making of appropriate length the connecting rod already
mentioned.

I, NEWNHAM BROWNE, of 73 Cheapside, in the City of London, Fellow of the
Institute of Patent Agents do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SUSPENDING AND PREVENTING THE BATTLING
OF WINDOW-SASHES OR FRAMES AND BLINDS MORE ESPECIALLY THOSE OF RAILWAY,
TRAM, AND OTHER CARS AND VEHICLES," which Invention has been communicated
to me from abroad by James Seed, of Southbrook, in the Provincial District of
Canterbury, in the Colony of New Zealand, Manufacturer, and Henry Abel Flatman,
of Southbrook aforesaid, Engineer, and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement
reference being had to the accompanying sheet of drawings and to the letter and
figures marked thereon :-
This Invention relates to an apparatus intended to be fixed to the movable frames
or sashes of the windows of Railway Carriagos, Tram Cars, and the like, and to the
frames of the blinds and shutters with which such windows are fitted, and consists of
an arrangement of parts by which the sash is held firmly against the fixed frame in
such manner as to provent its rattling.
It will be obvious that this Invention admits of considerable variation in the shape
and arrangement of its various parts and I therefore proceed to describe the form
which has been found most advantageous but without restricting the Invention to the
exact construction set forth.
According to this Invention there is fastened to the side and top edges of the window
sash-blind frame, or the like a bracket in the front edge of which is a groove in which
works a spring which is attached to the bracket and which serves to force forward a
tongue against the window-frame thus cramping one side of the sash with the
frame the whole length of the sash, and the other side, the whole length of the
tongue.
For the purpose of releasing the sash and allowing it to move freely up and down
a lever is connected with the tongue by a pin or other suitable joint and pivoted in
the groove of the bracket, and, to the long end of this lever is attached a connecting-
rod which passes along the inside of the top of the bracket and is turned at right
angles through a curved slot in the same, and is connected to a raising handle which
is, by preference, pivoted on a boss on the bracket.
Thus on lifting or lowering the sashes by the movement of the handle motion is
given to the lever, and the tongue is drawn back into the groove in the bracket, but
on the handle being released the tongue is repelled by the spring and the sash
effectually suspended and rattling prevented.
A cap covers the top of the bracket and prevents the entrance of dust and rain and
may be dovetailed to the bracket.

page_text: The handle, by which the sash is released, may be fixed to work in any position
along the top of the sash by making of appropriate length the connecting rod already
mentioned.
In the accompanying sheet of drawings Fig. 1, is an elevation of my invention
applied to a carriage window. Fig. 2, represents the same partly in section with the
front plate partly removed. Fig. 3, is a side elevation. Fig. 4, is a plan, Fig. 5,
an elevation of a modified form of the cap-piece and the remainder of the drawings
represent various parts separately.
A, indicates the window-frame; B, the sash; D, a bracket screwed or otherwise
fastened to the sash; C, is the tongue by which the sash is held when the apparatus
is in action and which is forced outwards by the spring F. To the tongue C is
jointed the lever E, to the other end of which is attached to the connecting-rod G,
which rod is formed with the end turned at right angles to pass through a curved
slot in the bracket and is thus connected with the handle Ef which is pivoted on a
boss which forms part of the bracket D. A cap I covers the upper edge of the
bracket to which it may be, conveniently, dove-tailed as shown in Fig. 3.
The handle H may be placed either in the centre or in such other position at the
top of the sash as may be desired, the connecting-rod G being made of corresponding
length, and if such position requires that the boss be beyond the end of the
bracket D such boss may be attached to or made to form part of an extension of
the cap I through which the curved slot for the connecting-rod G must in such case
he made as shown in Fig. 5.
In lifting or lowering the sash the handle H is raised, which pressing the
connecting-rod G against the upper end of the lever E draws back the tongue-
piece and allows the sash to be raised or lowered as required.
On the handle H being released the tongue C is pushed forward by the spring F
and its whole length pressed against the frame A of the window, thereby cramping
the other side of the window sash B throughout its entire length with the frame
with sufficient force to suspend the sash and effectually prevent the same from
rattling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my Foreign Correspondents 1 declare that what I claim is :
Constructing apparatus for susponding and preventing the rattling of window
sashes or frames and blinds more especially those of railway, tram and other cars
and vehicles substantially in the manner and for the purposes loreinbefore described
and set forth.
In fasteners for railway and other carriage-windows and the like the combination
in the bracket D, of the tongue C, the spring F, the lever E, the connecting rod I
and the handle H.
