Improvements in Securing the Blind Cords of Venetian, Roller, and
other Blinds to Retain the Blind at any Desired Height.
We WILLIAM BENN of 52 North Road, Lancaster, Carpet Fitter and RICHARD
CAPSTICK of 18 Bulk Street, Lancaster, Tin Plate Worker, do hereby declare the
nature of our said invention to be as follows:-
This invention relates to the construction of a simple and reliable self-acting catch
through which the cord or cords of a venetian or roller blind may pass and so be
firmly held and yet capable of being easily released.
This improved catcli consists of a metallic bracket or casing in which is mounted a
pivoted plate the edge of this plate at a suitable angle presses constantly against the
one side of the bracket or casing under the influence of a suitable spring and so
as to firmly grip the cord or cords which are passed between the two. A knob
projecting through the opposite side of the box enables the blade (by pressing
such knob) to be turned partially upon its pivot and thus to release the cords at will.
This improved catch is entirely independent of the blind roller and is also suitable.
for the double cords of venetian blinds for which purpose it dispenses with the
ordinary tumblers and additional releasing cord necessitated thereby.

We WILLIAM BENN of 52 North Road, Lancaster, Carpet Fitter and RICHARD
CAPSTICK of 18 Bulk Street, Lancaster Tin Plate Worker do hereby declare the
nature of our said 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 the construction of a simple and reliable self-acting catch
through which the cord or cords of a venetian or roller blind may pass and so be firmly
held and yet capable of being instantly and easily released.
On the accompanying drawing we illustrate in Fig. 1 a front view and in Fig. 2 a
side sectional view of a window frame and blind roller having our improved self-acting
catch applied théroto. Fig. 3 is a side sectional view (full size) of my improved
catch alone and Fig. 4 a front view (full size) of the bracket or casing (with the front
removed) disclosing our improved catch and its spring secured therein.
In Figs. 1 and 2 a represents the window frame-work and a roller blind applied
thereto in the ordinary manner.
Our improved self-acting catch consists of a metallic bracket or casing c affixed
upon the window frame and in or between the sides of which is mounted a pivoted
plate d. The bottom edge of this pivoted plate is constantly pressed against the back
of the bracket e under the influence of a blade-spring e (secured in the sides of such
bracket) and thus firmly and self-actingly grips the blind cord g which is passed
between the two. A knob affixed to the plate d and projecting through the opposite
or front of the casing enables the pivoted plate d (by simply pressing such knob) to
be turned partially upon its pivots to the position indicated in dotted lines in Fig. 3-
and thus to release the cord g at will.
This improved self-acting catch it will be observed is entirely independent of the
blind roller and is also suitable for securing the double cords of venetian blinds for
which purpose it dispenses with the ordinary tumblers and additional releasing cord
necessitated thereby.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we hereby declare that
what we claim is
1st. The improvements in apparatus for securing the cords of venetian, roller and
other blinds substantially as and for the purpose herein before described.
2nd. In a self-acting catch for securing the cords of blinds the employment of a
pivoted plate in combination with a spring and actuating knob, all mounted and
operating substantially as hereinbefore described and illustrated on the accompanying
drawing.
