A NEW OR IMPROVED BINDING FOR SCAFFOLDING AND OTHER PURPOSES
Year: 1881

page_text: LETTERS PATENT to James Rettie, of Hatton Garden, in the County of
Middlesex, Engineer, for an Invention of "A NEW OR IMPROVED BINDING
FOR SCAFFOLDING AND OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said James Rettie at, the Office
of the Commissioners of Patents on the 23rd March 1881.
JAMES RETTIE, of Hatton Garden, in the County of Middlesex, Engineer.
"A NEW OR IMPROVED BINDING FOR SCAFFOLDING AND OTHER PURPOSES."
This Invention relates to a new or improved binding for scaffolding and other
purposes.
According to my Invention I employ a chain, having at one end a tongue and at
the other a loop to slip over same. The tongue is, say, from four to six inches in
length, and is provided with a row of rectangular slots or several rows not exactly
opposite one another, but graduated into position to give varifying dimentions from
either of its extremities. The size of the loop at the other end of the chain is of
similar size and shape to the cross section of said tongue, so that it may be easily
slipped on to same. The chain is passed round the two or more articles to be
bound (say, scaffold poles) and the loop is slipped over the tongue until the chain
is nearly tight. A flat wedge is then inserted at the back of the loop into one of
the slots in the tongue and driven down, so as to force the loop further over and so
tighten the chain. It may happen that the wedge will go right home and not
sufficiently tighten the chain, in which case another wedge (or the same removed) is
inserted into the next slot and the process is repeated. To make the chain adjustable
to greatly varying dimentions of the articles to be bound I construct it in two
pieces. One inner end is provided with a hook and the other with such shaped
links that this hook will enter, and as the hook may be inserted into any one of
these links; the chain may at once be made of the length required.

"A NEW OR IMPROVED BINDING FOR SCAFFOLDING AND OTHER PURPOSES.”
This Invention relates to a new or improved binding for scaffolding and other
purposes.
In the accompanying Drawings Fig. 1 is a sectional plan view of two scaffold
poles, shewing my Invention applied as a binding for same; Fig. 2 is an elevation
of part of the binding; and Fig. 3 is a plan view of a modification.
According to my Invention I employ a chain A, having at one end a tongue
piece B and at the other a loop C to slip over same. The tongue piece B is pro-
vided with rectangular slots 6 overlapping in the different rows, as shown, so as
to give varying dimensions from the extremities of the tongue piece. The eye
of the loop C at the other end of the chain is of similar sizo and shape to the cross
section of said tongue piece B, so that it may be easily slipped over same. The
chain is passed round the two or more articles D to be bound (say, scaffold poles)
and the loop is slipped onto the tongue until the chain is nearly tight. A wedge É
is then inserted at the back of the loop into one of the slots 6 in the tongue piece
and driven down, so as to force the loop further onto the tongue piece and so
tighten the chain. It may happen that the wedge will go right home and not
sufficiently tighten the chain, in which case another wedge (or the same removed)
is inserted into the next slot and the process is repeated. To make the chain
adjustable to varying dimensions of the articles to be bound I construct it in two
or more pieces. In the Drawings it is shown constructed in two pieces. One inner
end is provided with a hook G, the chain being of such shaped links that this hook
will enter same, and as the hook may be inserted into any one of these links desired
the chain may at once be made of the length required. In the modification seen
at Fig. 3 the book is shown as constructed in one-piece with the loop C, the length
of chain required being all attached to tongue piece B. Tongue piece B may be set
up at the edge, as shown at H, Fig. 3, to prevent loop C coming off or being lost.
When desired an intermediate length of chain may be used for varying the length
of the binding. This length would have a hook at one end.
In using this binder for scaffolding it is wrapped in the same direction over the
joints as rope would be.
When desired, a rope or band may be used instead of chain, but I prefer-chain,
especially for scaffolding.
I claim as my Invention to be secured by the herein before in part recited Letters
Patent, the improved binding for scaffolding and other purposes, substantially as.
shown and described.
In witness whereof, I, the said James Rettie, have hereunto set my hand
and seal, this Twenty third day of September, in the year of our Lord One
thousand eight hundred and eighty-one
