We JOSEPH JAMES DAY and THOMAS ISAAC DAY both of 2ª Prince of Wales Road
Kentish Town Middlesex Sanitary Engineers 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 :-
Our invention has for its object the more simple and quickly fastening or unfasten-
ing of cords ropes and such like and is more especially applicable for securely holding
the sheet lines of tarpaulings used on railway goods trucks and similar purposes and
consists in casting or otherwise forming a back plate with a pivot or bearing in the
centre cast to a suitable shape to prevent the front plate from moving round, the front
plate is so placed on the pivot or bearing that it works loosely thereon, and is secured
on the pivot by a split or solid pin or otherwise. When the cord or rope is simply
twisted a half or more turns round between the two plates the plates form a firm hold
or clutch, and is also capable of holding one or more cords and can be placed in any
position that may be required on the trucks. Our apparatus is also applicable for
fastening the cordage for window blinds and other similar purposes.
In order that our invention may be more fully understood we have appended hereto
a sheet of drawings in which Fig. 1 is a sectional view having a movable head and
Fig. 2. is a plan of same.
Referring more particularly to Fig. 1 A is a loose plate fitting loosely over the
pivot or bearing B the top which is formed square or other suitable shape to prevent
the plate turning, having cars or projections or other convenient means of fixing the
back plate to the trucks or any other object for which our invention is applicable, the
loose plate A is secured in position by the pin or split cotter D. the cord is passed a
half turn or more round the pivot or bearing B and on being pulled tight the plate A
gives and clips the cord tightly against the sides of the pivot or bearing B. It will
then be found that by this means the cord is held firmly in position and that it is
impossible to slip or give until the end of the cord is pulled from over the pivot B by
the person in charge.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed, we declare that what we claim is-
The plate A fitting loosely on the pivot B and securely held in position by means
of the cotter or pin D or other means for the purposes described in the Specification
and Drawings.
