Improvements in Apparatus for Holding and Gripping Cords and
other like Substances,
We FRIEDRICH ZAHN, Machinist of Fohrbellinerstrasse 6, Spandau and
OTTO GAERTIG, Merchant of Mendelsohn Strasse 11, Berlin both in the Empire
of Germany, 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 primarily to an arrangement for holding and securing the
cords of roller blinds, but it may be used for other cords, ropes, bands etc.
Referring to the annexed drawing which will sorve to illustrate a mode of
performing the invention, Fig. 1 shows side view and section, Fig. 2 side view, and
Fig. 3 front view of the apparatus for holding cords or straps of rolling blinds,
clothes lines, and which can also be used for other purposos, in which the cord or
strap is automatically caught and kept in place; but the arrangement in question
has, above other arrangements of that kind, the advantage, that it cannot be
loosened by accidentally touching it, or by incompetent persons, as this depends on
the actuation of a simply operating mechanism.
The frame A, which, by means of two wooden screws, is fastened to the window
posts etc., has two shoulders B to receive the spindle of the lever C. These spindle
ends rest in grooves of B, and, by means of set screws cc, the axis of the lever C
can be brought nearer the face of A, just as the thickness of the cord or strap
requires. The lever C, the upper end of which is broadened and has a rasplike
inner face (ie., the side which is turned towards the cord or strap), always tends to
press this rasplike face against the strap.
Of great importance and a new feature of the arrangement in question is the
bolt D, which, running longitudinally through the lever C, terminates at one end in
a round button, whereas it has on its upper part a notch which is continued at
its lower end in the shape of an annular groove. In this groove a set screw 6 is
loosely fitted. As represented in the drawing, the upper end of the bolt D is held
in such a position that it is rendered impossible to raise the levor C, as the end
of D is pressed against the strip f. The lever can be disengaged, if the button
of D is turned so that the notch a has the opposite position, whereby D slides down
as far as the upper end of a will permit it, ie, the bolt D entirely disappears in C.
This arrangement therefore represents a safety catch which can as easily be
disengaged as it is to set it in operation.
In place of the notch and the part a which is slightly marked with a file, two
annular grooves connected with each other by a half thread could be employed.
The bolt D could also be represented as a sorow, with C as corresponding out.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
The cord or strap holder for rolling blinds, ropes and such like, which consists
of a lover C with bolt d, hinged in shoulders B on to the frame A, and the one side
of which lever can be pressed against the cord, thereby holding it; the safety catch
in said lever. consisting in a bolt D. which can be moved therein, and which, if

page_text: moved forward renders impossible the motion for turning and disengaging the
holding arrangement, all substantially as illustrated and described.
Dated this 7th day of March 1895.
