2 Claims.
This invention relates to Venetian blinds and
it is one object of the invention to provide blinds
of this character having an improved form of
upper head bar and arrangement of ropes or
cords for raising or lowering the blinds and angu
larly adjusting slats thereof.
Another object of the invention is to so form
the head bar that slots are provided longitudi
nally therein and guide pulleys are mounted‘ in‘

Having thus described the invention, what is
claimed is:
