page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex for an
Invention of A NEW OR IMPROVED CORD-FASTENER FOR WINDOW BLINDS,
ALSO APPLICABLE GENERALLY FOR FASTENING STRINGS, ROPES, CHAINS OR
TAPES communicated to him from abroad by D. W. Ernsting, of Bremen, in
the German empire
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 13th July 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "A NEW OR IMPROVED
CORD-FASTENER FOR WINDOW BLINDS, ALSO APPLICABLE GENERALLY FOR FASTENING
STRINGS, ROPES, CHAINS OR TAPES," a communication to me from abroad by
D. W. Ernsting, of Bremen, in the German Empire,
This invention relates to cord fasteners, for window blinds and other purposes
and has for its object to stop and secure strings, ropes, chains or tapes in the
required position by simply drawing the cord side-ways.
For this purpose I fix to the side-post of the window-frame or to any analogous
support a bracket to which is,pivoted a vertically movable lever forming a channel
or guide for the cord. To the said lever is pivoted another lever, also movable in
a vertical plane and provided with a guide or channel for the cord.
If the cord is pulled vertically the two levers are also placed vertical and allow
the cord to pass without hindrance, the guide of the first lover being turned
towards the bracket or post, while the guide of the second lever is turned
outward,
For securing the cord, the latter need only be pulled sideways (in a plane
perpendicular to the axes of the pivots of the levers), thereby causing the levers to
turn sideways and clip the cord between them.

the said Herbert John Haddan in the Patent Office on the 11th January
1884.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "A NEW OR IMPROVED
CORD-FASTENER FOR WINDOW BLINDS, ALSO APPLICABLE GENERALLY FOR FASTENING
STRINGS, ROPES, CHAINS OR TAPES," a communication to me from abroad by
D. W. Ernsting, of Bremen, in the German Empire.
This invention relates to apparatus for stopping and securing strings, ropes,
chains or tapes, at the required moment. The peculiar advantage of the appliance
consists in enabling a person to fasten and secure the string or chain in the
required position by simply drawing the same side ways and then releasing it,
the arrangement on the other hand permitting to move the cord easily up and
down.
In the following description reference will be made to the accompanying
drawings Figs. 1 to 3, which illustrate the invention.
The apparatus comprises a bracket A fixed by means of screws to the window
.frame, scaffolding or any analogous support, and the two levers B and C pivoted
on the pins D and E and forming channels or guides.
The cord or chain, connected with the blind or with any other appliance or load
to be drawn by the same means, passes between the levers B and C and may easily
be moved up and down when the levers are in the position represented by Fig. 2,
so as to permit the raising or lowering of the blind or load into any required
position.
If the lower end of the cord is pulled sideways in the direction of the arrow,
the lever B is turned round the pin D, so as to close the mouth formed by the
edges and g of the levers B and C, whereby the cord or chain is clipped and
secured. If subsequently the cord or chain is released, the levers B and C assume
the position shown by Fig. 3 owing to the friction of the cord or chain in the
mouth, in which position the mouth of the levers B and C still more firmly secures
.and maintains the cord.
CLAIM
An appliance for automatically securing cords (strings, ropes, chains or tapes)
which comprises the channelled levers or open sleeves B and C pivoted on the
pins. D and E and secured to a bracket A, the said levers or sleeves.being adapted
to guide and grip the cord in the manner substantially as described.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 11th day of January A.D. 1884.
HJ HADDAN (L.S.)
