PROVISIONAL SPECIFICATION.
A New or Improved Device for Securing Scaffolding or the like.
I JOHN WILLIAM SHERING, of Fordingbridge, Hants, Builder and Contractor,
do hereby declare the nature of this invention to be as follows :-
My invention relates to a new or improved device for securing scaffolding or
the like, and has for its object to dispense with the use of rope lashings or
fastenings heretofore employed and to provide means for fastening the scaffold-
poles or the like together, in a more secure and ready manner than formerly.
According to my invention, I provide a curved iron or other plate to one end of
which is secured a twisted linked chain of suitable length.
Near the other end of the said curved plate I form an opening through which
passes the hooked end of a rod, which rod is screw-threaded at its other end, and
provided with a tapped winged, or other handle, so that same can be screwed up
or down upon the screw-threaded end of the hooked rod as desired.
In operation the curved plate, which is provided on its under or concave side,
with downwardly projecting teeth or spikes, is placed against the scaffold-poles or
the like, where two join or cross one another, and the chain is brought over and
around the joint and one of the links placed over the hooked end of the rod.
The tapped handle is then screwed up along the screw-threaded end of the rod,
by which means the chain is made taut around the crossed scaffold-poles or the
like.

COMPLETE SPECIFICATION.
A New or Improved Device for Securing Scaffolding or the like.
I JOHN WILLIAM SHERING, of Fordingbridge, Hants, Builder and Contractor,
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 :―
My invention relates to a new or improved device for securing scaffolding or the
like, and has for its object to dispense with the use of rope lashings or fastenings
heretofore employed and to provide means for fastening the scaffold-poles or the
like together, in a more secure and ready manner than formerly.
According to my invention, I provide a curved iron or other plate to one end of
which is secured a twisted linked chain of suitable length.
Near the other end of the said curved plate I form an opening through which
passes the hooked end of a rod, which rod is screw-threaded at its other end, and
provided with a tapped winged or other handle, so that same can be screwed
up or down upon the screw-threaded end of the hooked rod as desired.
In operation the curved plate,--which is provided on its under or concave side,
with downwardly projecting teeth or spikes, is placed against the scaffold-poles or
the like, where two join or cross one another, and the chain is brought over and
around the joint and one of the links placed over the hooked end of the rod.

page_text: The tapped handle is then screwed up along the screw-threaded end of the rod,
by which means the chain is made taut around the crossed scaffold-poles or the
like.
And in order that the said invention may be the more readily understood, I
have shewn the same upon the accompanying sheet of illustrative drawings,
wherein :
Fig. 1 is a side view of the device.
Fig. 2 being an end view thereof, whilst
Fig. 3 is a view of a portion of scaffolding with my invention applied thereto.
Referring to the drawings a is a cast iron or other plate, centrally curved as
shown in Fig. 1 and provided with downwardly projecting teeth or spikes a¹ one its
inner or concave side. To one end of this said curved plate is secured a suitable
length of chain 6, while through an opening in the other end of the plate, is passed
a rod c screw-threaded at one end and fashioned in the form of a hook at the
other end c².
Upon the screw-threaded end c¹ of the rod c, is provided a tapped handle d,
adapted to work upon such screw-threaded end c¹ in order to increase or diminish
the length of rod projecting through the opposite side of the plate a. Referring
to Fig. 3 where I have shewn a front and rear view of the invention in operation,
the curved plate a is placed transversely upon the vertical scaffold-pole e
immediately below the horizontal pole f which crosses the vertical one, with the
concave and spiked face against the said pole, and the chain b is passed under or
behind the horizontal pole f, around the vertical pole e and then behind the
horizontal pole again to the hooked end c² of the rod c to which it is attached by
any suitable link. The handled is then screwed up along the threaded rod, by
which means the chain is rendered taut around the crossed scaffold-poles or the
like, and the plate a bears firmly against same.
The will be obvious that the device can be arranged upon the scaffolding or the
like, in other ways, as for instance where two scaffold-poles or the like cross one
another in an oblique direction.
I preferably form the chain of twisted links, though I have shewn plain ones in
the drawings for convenience, so that they may lie closer against the object or
objects which they surround.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-.
The improved device for securing scaffolding or the like, consisting of a
centrally curved plate having downwardly projecting teeth on its concave side,
and a twisted linked or other chain secured to one end, a hooked and screw-
threaded rod passing through the other end and being provided with a tapped
tightening handle, substantially as and for the purpose described and illustrated by
the drawings.
