IMPROVED DEVICE FOR SIMULTANEOUSLY OPENING THE LIGHTS OR SASHES OF GARDEN FRAMES
Year: 1884

page_text: I DUNCAN MCKELLAR N° 28 Ladbroke Grove Road, Kensington in the County
of Middlesex, Florist, do hereby declare the nature of my Invention for "IMPROVED
DEVICE FOR SIMULTANEOUSLY OPENING THE LIGHTS OR SASHES OF GARDEN
FRAMES, to be as follows:-
This Invention provides for the simultaneous opening of the 'lights or sashes of
long or short lengths of Garden frames which may be made in the usual way and
fixed on wood brick or other enclosure.
The sash has placed on each side two open hinges which fit and turns in the
sockets fixed to the bars between the sashes and at both ends.
The sash is strengthened in the usual way with a flat iron bar fixed across
the Centre underneath with the ends turned up at the sides of the sash and
terminating with eyelets or holes to receive the lower ends of the lifting Chains
or Cords.
In the Centre of each of the cross bars and ends are fixed strong iron uprights
with socket joint at top to receive the lower end of Quadrant.
The said Quadrants are made light or heavy according to the weight of the
sash to be lifted, they are fixed by bolt and nut to the uprights and turn
freely.
Each Quadrant has two arms with holes for upper ends of the lifting Chains or
Cords and a bolt hole at top for fixing the Connecting rod which may be of
ordinary Iron bar, Gas or Steam barrel heavy or light according to the weight
of the Sashes.
The Connecting rod has a Crosshole opposite every upright for bolt and nut to
connect all the Quadrants used along the whole length of the frame.
A strong handle or lever is fixed to one or both of the end Quadrants for the
opening and shutting of the lights to any extent requisite or desired.
When the Chains or Cords are fixed to the lights and arms of the Quadrants
and the lights are shut the Quadrants stand perpendicular and are kept in that

page_text: position by a Semi Circular iron racket or Stop with holes fixed to the end of
frame and alongside of the handle which has a hole and pin.
When the handle is moved the Quadrants are thrown off the perpendicular and
have with the connecting rod a tendency to fall over which assists or acts as a
Counterpoise to the weight of the sashes to be opened so that all the lights on long
or short frames may be simultaneously opened either to the right or left to avoid
Cutting Winds by this Invention.
This system will apply to all existing lights and frames.

of Middlesex, Florist do hereby declare the nature of my invention for "IMPROVED
DEVICE FOR SIMULTANEOUSLY OPENING THE LIGHTS OR SASHES OF GARDEN
FRAMES" to be as follows and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
This Invention provides for the simultaneous opening of the Lights or Sashes of
long or short lengths of Garden frames which may be made in the usual way and
fixed on wood, brick or other enclosure.
The Sash has placed on each side two open hinges which fit and turns in the
Sockets fixed in the bars between the Sashes and at both ends.
The Sash is strengthened in the usual way with a flat iron bar fixed across the
Centre underneath with the ends turned up at the sides of the Sash and terminating
with eyelets or holes to receive the Lower ends of the lifting Chains or Cords.
In the Centre of the Cross bars and ends are fixed strong iron uprights with
socket joint at top to receive the lower end of Quadrant.
The said Quadrants are made light or heavy according to the weight of the Sash
to be lifted they are fixed by bolt and nut to the uprights and turn freely.
Each Quadrant has two Arms with Holes for upper ends of the lifting Chains
or cords and a bolt hole at top for fixing the connecting rod which may be of
ordinary iron bar, Gas or Steam barrel heavy or light according to the weight
of the Sashes.
The Connecting rod has a Crosshole opposite every upright for bolt and nut to
connect all the Quadrants used along the whole length of the Frame.
A strong handle or lever is fixed to one or both of the end Quadrants for the
opening or shutting of the lights to any extent requisite or desired.
When the Chains or Cords are fixed to the lights and arms of the Quadrants
and the lights are shut the two Quadrants stand perpendicular and are kept in
that position by a Semi-Circular iron racket or stop with holes fixed to the end
of frame and alongside of the handle which has a hole and pin.
When the handle is moved the Quadrants are thrown off the perpendicular and
have with the Connecting rod a tendency to fall over which assists or acts as a
Counterpoise to the weight of the Sashes to be opened so that all the lights on long
or short frames may be simultaneously opened either to the right or left to avoid
Cutting Winds by this Invention.
This system will apply to all existing lights and frames.
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
The Quadrant and lever to be fixed at each end of a length of new or old Garden
frames and the lifting Chains and uprights over each Sash and by simply lowering

page_text: the lever at either end, which lever works in the Quadrant the whole of the lights
can be lifted to any particular height and any of the lights can be left closed by
merely disconnecting the lifting Chains from those Sashes, which Chains would
hang loose while the other Sashes are being raised or lowered.
