A NEW OR IMPROVED BINDING FOR PROVISIONALFICATION
Year: 1882

page_text: LETTERS PATENT to James Rottie of Hatton Garden in the County of
Middlesex Engineer for an Invention of "A NEW OR IMPROVED BINDING FOR
PROVISIONAL SPECIFICATION left by the said James Rettie at the Office
of the Commissioners of Patents on the 20th March 1882,
JAMES RETTIE of Hatton Garden in the County of Middlesex Engineer;
"A NEW OR IMPROVED BINDING FOR SCAFFOLDING
"
This invention relates to a new or improved binding for scaffolding
According to my invention I employ a chain to bind together scaffold poles and
such like articles in lieu of rope as heretofore used, and in order to allow of the
tightening wedge being driven in between the chain and the poles to be bound I
enclose a small portion of the chain with a small length of tubing just large enough
to slip round on the chain which is provided at one end with a hook which can be
hooked into any one of the links of the chain. The cliain when to be used is
passed round the poles to be bound together and made as tight as possible by
hooking the hook at its end into one of the links and leaving the said piece of
tubing opposite the line of junction of the poles. The wedge suitably formed for
the purpose is then driven in between the poles and the piece of tubing. The
wedge in the ordinary case of round poles is formed somewhat as a triangle in
cross section one side bearing against the tubing and one side against each of the
two poles.

by the said James Rettie in the Great Seal Patent Office on the 20th September
1882.
JAMES RETTIE of Hatton Garden in the County of Middlesex Engineer
"A NEW OR IMPROVED BINDING FOR SCAFFOLDING"
This invention relates to a new or improved binding for scaffolding.
And in order that my Invention may be clearly understood and readily carried
into effect I will now proceed to describe same with the aid of the accompanying
drawings reference being had to the letters and figures marked thereon and in
which Fig 1 is a sectional plan of two scaffold poles bound together according to
my invention and Figs 2 & 3 are vertical front and back elevations respectively of
the same drawn to a smaller scale.
According to my invention I employ a chain A to bind together scaffold poles
and such like articles B and C in lieu of rope as heretofore used and in order to
allow of the tightening wedge D being driven in between the chain and the poles
to be bound together I enclose a portion of the chain with a small length of
.tubing E just large enough in diameter to slip round on the chain. This Chain is
provided at one end with a hook G which can be hooked into any one of the links
of the chain, and at the other end with a ring or enlarged link to prevent the
tube E slipping off. The chain when to be used is passed round the poles to be
bound together and made as tight as possible by hooking the hook at its end into
one of the links and leaving the said piece of tubing E opposite the line of
junction of the peles The wedge D suitably formed for the purpose and made of
wood or other suitable material is then driven in between the poles and the piece
of tubing on the chain thus tightening the chain round the poles. The wedge in
the ordinary case of round poles is formed somewhat of triangular form on cross
section one side of it bearing against the tubing and one side against each of the
two poles. Tube E is shewn in end view below Fig 1 as is also side view of
wedge D.
I claim as iny invention to be secured by the herein before in part recited Letters
Patent the combination of chain A, tube E, and wedge D substantially as and for
the purpose or purposes herein before set forth and described and illustrated in the
accompanying drawings.
In witness whereof I the said James Rettie have hereunto set my hand and
seal this nineteenth day of September Que thousand eight hundred and
eighty two.
