Improvements in Venetian Window Blinds.
I, DAVID CLARKE, of 21, Langley Road Small Heath Birmingham, in the-
County of Warwick, Engineer, and I ARTHUR GEORGE JOINER, of 330, Coventry
Road Small Heath, Birmingham in the County of Warwick, Manufacturer, do-
hereby declare the nature of this invention to be as follows:-
The manufacture, preperation, and substitution of corrugated paper, or cloth and
paper in combination for the thin laths of Venetian blinds, now made of wood,.
and also of metal according to a previous Patent granted' to the said David Clarke
in the year 1864, No. 1097.
For this purpose we use sheets of paper cemented together, or paper manu-
factured in one thickness, or paper combined with cloth manufactured from cotton,
linen or other fibreous material, according to the length and strength of the lath
required. The laths when cut into strips of the necessary width are corrugated.
longitudinally with a series of small corrugations, plain or ornamental, for the
purpose of giving strength and rigidity to the same. By this means we secure
an exceedingly light durable, cheap, and cool blind as a protector from the heat
and rays of the sun.
