Improvements in venetian
il JOHN MANTTAN, of the City of Wellington, in the Colony of New Zealan
Merchant do hereby declare the nature of this invention to be as follows:-
In my invention I combine lightness, cheapness, and beauty and avoid the
inconvenience of weight of blind, and the difficulties connected with pully cords, us
applied to blinds at present in use. For this purpose the lathes, with the exception
of the top and bottom lathes, are made of pulp corrugated longitudinally, and
either decorated or in monochrome. The top and bottom lathes are made of wood
or metal or à combination of wood, metal, and pulp, or of two of these materials.
The lathes are supported by ladder tapes or other suitable materials.
The lathes are raised or lowered by the action of a spring roller placed along
the top of the blind with cords working round or from the spring roller and running
through the lathes of the blind.
The blind can be stopped at any height, can be hung by eyelets or brackets to
the window frame and removed at will. Wooden lathes may be used throughout the
blind, with strong roller springs, but pulp lathes are preferred.

Improvements in Venetian Blinds.
I, JOHN MANTTAN of the City of Wellington in the Colony of New Zealand,
Merchant, do hereby declare the nature of my invention for "Improvements
in Venetian Blinds," and in what manner the samo is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention consists in combining tho Venetian louvre and roller type of
blind in such a way as to obtain the advantages of both of them. It consists
essentially in providing spring barrels, rollers, spools or drums constructed and
acting in the same manuer as the roller in a spring blind and operating the
supporting cords of the Venetian blind. These barrels, rollers, spools or drums
are by preference placed over the Venetian blind, but they may be placed in the
side of the window casement or in any other position whore the supporting cords
could be conveniently led to them. Thus arranged the Venetian blind can be run
up or down and fixed in any position as easily and in the same manner as an
ordinary spring blind.
In the annexed sheet of explanatory drawings, Fig. 1. is a front elevation of a
"roller Vonetian" blind according to the present invention, and Fig. 2. is a
sectional end elevation of same. "A" is an ordinary spring roller monnted in
a box B. which may be ornamented externally. This roller has fastened to it the

page_text: supporting cords C. of the Venetian louvre blind by means of which it supports
the blind and controls its position.
In order to reduce the weight of the blind and thereby fit it to be operated by
an ordinary spring roller which would be too weak to work an ordinary wooden
slat blind of any considerable size, the slats are made of thin papier mache,
Willesden paper, indurated fibre, or similar substance, corrugated along the length
to obtain the necessary stiffness; the appearance is also improved by the corruga-
tions. I do not restrict myself to the special construction of blind heroin
described and shown in the accompanying drawings, so long as the nature of the
invention is retained.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
The employment of a spring roller, barrel, spool or drum for carrying and
operating the supporting cords of a Venetian louvre blind substantially as
specified.
