JOSEPH SCHALHAS, of 119, Charlotte Street, Fitzroy Square, London, native of
Kendl, Lower Austria. "IMPROVEMENTS IN VENETIAN BLINDS."
They are constructed on a new system, and are a considerable improvement on all
blinds hitherto in use, are superior, more comfortable, of greater durability, and
materially enhance the value of a house.
As the accompanying Drawing will show, nothing of the blinds is to be seen
when drawn up, and no dimunition of light or disfigurment of the windows is
suffered.
Considering this Invention to deserve to be patented, I subjoin a Specification.
The superiority consists in resisting every kind of weather, and if either merely
drawn up or let down slantingly outside the window, neither sun, rain, or wind can
cause damage.
The blinds may be safely let down in a room of which the upper part of the
window are open, and if unoccupied for any length of time, being thus properly
ventilated, will be effectually protected against the weather; and the injuries done
to curtains, carpets, and other kind of furniture are thereby obviated. These
blinds are more durable, having, instead of bands, chains to hold them together,
and protecting likewise the cord, by which the blinds are moved, from external
influences.
In order that the cord, division III., No. 9, is thus protected, it moves in running
ledges (see No. 7), and, as may be noticed in division III., across two rollers into
the room, thus enabling to either let down or draw up the blinds in the left corner
of the window without opening it.
In the right corner of the window is the cord (see div. II., No. 6,) for the drawing
up of the upper window, which is however concealed, as also the blinds, by the
curtains of the window. This system offers a special advantage to cultivators of
Howers, as the blinds can be let down without touching the plants.
Division I., view of the window from the outside; No. 7, the running ledge,
n which the cord and the pegs of the blind board move; No. 10, chain to unite
he blind boards.
