Improvements in Scaffolding Binders or Lashings.
I DENZIL JOIN JARVIS of 42 Humberstone Road Leicester in the County of
Leicestershire Builder do hereby declare the nature of this invention to be as
follows:-
$3
The object of my invention is for securing Scaffolding and Scaffold Poles by
means of a Chain and Screw instead of the usual "Scaffold Cord' or binder and
wedges so as to clamp or bind two or more Poles or pieces of wood or planks
together quickly and securely. Ropes being effected by the weather often become
unsafe and require some time and skill to fix.
My invention consists of a chain (preferably twisted or harness chain) with a
long screw and two shackles one is plain and the other screwed. The Screw has
a large head with one or more tommy holes for turning. The chain is fixed at one
The
end to one shackle and hooked into the nearest link to the other Shackle.
chain is then tightened by turning the screw with a loose or fixed tommy bar.
I sometimes substitute for the chain a wire rope with two spliced eyes one at
each end.
These binders may be used for other purposes the length of chain being made
suitable.

Improvements in Scaffolding Binders or Lashings.
I DENZIL JOHN JARVIS of 42 Humberstone Road Leicester in the County of
Leicestershire Builder 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:―
The object of my invention is for securing Scaffolding and Scaffold Poles by
means of a Chain and Screw instead of the usual Scaffold Cord or Lashing and
wedges so as to clamp or bind two or more Poles together or to bind any two or
more Beams, Scantlings, Planks or Poles together as the case may be, quickly and
securely. Ropes or Cords and wedges being effected by the weather become loose
unsafe and require much time and skill to fix.
My invention consists of a Chain either open link flat or twisted with a long
Screw and two Shackles, one Shackle has a plain hole and a fixed washer to keep
it in place. The other Shackle is screwed so as to travel on the Screw. The Screw

page_text: has a large head with one or more holes for turning with a Tommy-bar or the head
of the Screw may be fitted with a sliding handle.
Two Stirrups are attached to the Shackles one with a hook and the other with
an eye one end of the Chain is attached to the eye of the Stirrup and after being
passed round the Poles the nearest link is hooked on to the open hook of the other
Stirrup and the Screw tightened.
In the accompanying Drawing Fig. 1. is a Plan and Fig. 2. is an elevation
shewing my invention as applied to two crossed Scaffold Poles. A is an upright
Pole and B another at right angles to it. C, is the Screw. D, is the fixed Shackle.
E, is the travelling Shackle. F is the eye Stirrup. G is the hook Stirrup. H is
the Chain made various lengths to suit different requirements. I do not bind
myself to the arrangement of the Chain and Screw as shewn in the drawing. In
some cases the Screw may be more conveniently placed in the straight part of the
Chain (say at H) and the Chain may be sometimes crossed or passed round more
than once.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
A combined Chain and Screw with hook and Shackles etc. for binding or clamp-
ing Scaffolding and other purposes substantially as described and set forth.
