[Communicated from abroad by AXEL SABROE, of Hadersleben, Sleswick, in the
Empire of Germany.]
An Improved Device for Securing and Releasing Ropes or Cords.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a device for securing and releasing ropes or cords, which
is very suitable for use in cases where the rope or cord is to be instantly released
with certainty, for example for sheets of sails in sailing boats.
The improved device comprises a casing of cast metal wherein two toothed
sectors are provided each of which has a più or spike extending to the outside of
the said casing. To the rotary axis of one toothed sector is secured a handle while
in the interior of the casing is a spring adapted to press against the under side of
one toothed sector and which prevents the sectors being turned by their own
weight.
The rope or cord is secured by being wound round or over the casing behind the
pins or spikes; if it is to be released the toothed sectors are turned by operating
the handle, thus causing the pins or spikes to move into the interior of the casing so
that the rope or cord is set free.
In a modified arrangement the aforesaid toothed sectors are replaced by two
toothed wheels and the pins or spikes are provided at the ends of two racks which
engage with these toothed wheels.
In a further modification the aforesaid toothed sectors and wheels are dispensed
with. The handle turns upon a pivot in the interior of the casing, and the pins or
spikes are connected with the handle in such a manner that they will be drawn into
the casing when the handle is turned.

An Improved Device for Securing and Releasing Ropes or Cords.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 device for securing and releasing ropes or cords,
which is very suitable for use in cases where the rope or cord is to be instantly
released with certainty, for example for sheets of sails in sailing boats.
In the accompanying drawing,
Figures 1 to 3 show one form of the apparatus.
Figures 4 to 6 show a modification, and

page_text: Referring to Figures 1 to 3, the improved apparatus comprises a casing K of cast
metal wherein two toothed sectors are provided, each of which has a pin or spike T
extending to the outside of the said casing. To the rotary axis of one toothed
sector is secured a handle V, while in the interior of the casing is a spring F
adapted to press against the underside of one toothed sector and which prevents
the sectors being turned by their own weight.
The rope or cord is secured by being wound round or over the casing behind the
pins or spikes T; if it is to be released the toothed sectors are turned by operating
the handle V thus causing the pins or spikes T to move into the interior of the
casing so that the rope or cord is set free.
In the modified arrangement represented in Figures 4 to 6 the aforesaid toothed
sectors are replaced by two toothed wheels and the pins or spikes F are provided at
the ends of two racks which engage with these toothed wheels.
In the modification shown in Figures 7 to 9 the aforesaid toothed sectors and
wheels are dispensed with. The handle V turns upon a pivot V' in the interior of
the casing, and the pins or spikes T are connected with the handle in such a manner
that they will be drawn into the casing when the handle is operated in one direction
and forced out when the said handle is operated in the other direction.
If desired one of the pins T may be fixed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
A device for rapidly securing and releasing ropes and the like, characterized by
the feature that one or more pins, projecting from the casing and round which the
rope is fastened, can be drawn into the said casing by any suitable mechanism by
the movement of a lever arm or the like so that the rope may slip off and may thus
be released
