Improvements in or in connection with Blind Rollers.
I WILHELM HEITKAMP of Wehdem, Westphalia, in the Empire of Germany,
Merchant do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to a blind roller in which the material forming the blind
need not be nailed to the roller but is fastened thereto as hereinafter set forth.
The new blind roller is illustrated in the accompanying drawings in which
Fig. 1 shows the same in the closed state, and Fig. 2 shows the blind roller with
clamping bar in vertical section.
In the arrangement heretofore usually employed for fastening the blind
material to the roller the material has usually been nailed to the roller. But
this method very soon damaged the material besides affecting the appearance of
the blind.
Now this drawback is obviated according to the present invention by making
the roller of two longitudinal parts i.e. a thick or larger part a and a thin or
smaller part b.
The last mentioned bar b serves to hold the material by clamping the said
material against the bar a.
For this purpose the bar bis provided with a row of pins which fit into
corresponding recesses e in the bar a.
In the case of wooden rods a the holes c are advantageously lined with brass.
The barb is connected to the bar a at one end by means of the hinge d and at
the other end by means of a ring e or a collar clasp or other fastening of any
suitable character.
Instead of making the bar b with separate pins and making the bar a with holes c
corresponding therewith the bar b may be provided with a tongue or longitudinal
projection or projections (spring mounted or otherwise) which engages in a groove
in the bar a or the material may be held in between the bar b and the bar a in any
other suitable manner as desired.
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 :-
:-
1. A blind roller constructed of two bars or parts which together form the
complete roller a hinge permanently connecting said two parts together at one end
means to clasp or secure the opposite ends together and means provided on the
respective proximate faces of said two parts adapted to grip and firmly hold the
blind material placed there between combined arranged and acting substantially in
the manner and for the purposes herein before described.
2. A blind roller formed of two parts one of which such as 6 serves to clamp
the material against the other part such as a to which it is connected by a hinge
such as d said bars band a on their proximate faces being either provided with
pins or otherwise suitably formed or arranged for holding the blind material the
other ends of the bars being fastened together by means of a ring such as e all

herein before described and illustrated in the accompanying drawings.
