We, JOSHUA GEORGE MILLS, of Grange Road, West Kirby, Builder, and PETER
CAMPBELL, of 6, Montgomery Terrace, Hoylake, Joiner, both in the County of
Chester, do hereby declare the nature of this invention to be as follows:-
This invention has for its object an apparatus or appliance to be used in place
of rope for lashing scaffolding poles, and (or) supporting the ledgers on which
rest the planks, with a view to doing away with the accidents which so fre-
quently occur through faulty lashing, and through lashing ropes breaking, which
they are so liable to do when they get rotten through being left out in all
weathers.
One way of carrying our invention into effect is as follows:-
We provide a clip or its equivalent preferably roughened inside or provided
with teeth, and made in two halves so as to grasp the pole by the two ends of
the clip being drawn forcibly together by nuts and bolts. Pivoted to this clip
is another clip of similar construction, adapted to grasp another pole when it is
required to superimpose scaffold poles one above the other, or to grasp a hori-
zontal or cross pole. The two clips being pivoted enable the poles to be bound
together at any required angle, the pivot permitting of this being done.
In another arrangement we provide a hinged clip or its equivalent, preferably
roughened inside, and adapted to grasp the pole and be secured thereto by the
two ends of the clip being drawn forcibly together by a screw with lever at end,
or a bolt and nut or otherwise. This clip is provided at one side with a socket,
adapted to hold one end of the ledger, and fitted with a tightening device to
tighten the ledger in the socket. This socket may also be made to receive the
bottom of another pole when it is required to superimpose scaffolding poles one
above the other, and underneath the socket is a bracket or arm adapted to bear
against the side of the pole and strengthen the socket.
In action, a hinged clip is placed round each pole and closed, and fastened
thereto by screwing up the screw. When this is completed the ends of the
ledgers are placed in the sockets, also the ends of the superimposed poles if such
are required to be used, and the tightening device screwed up to keep them
tight. In this position the bracket rests against the pole and resists the strain on
the socket. Planks are then placed on the ledgers in the ordinary way.
In this manner an admirable substitute is provided for the ordinary rope lash-
ing. The device can be fixed to the poles before rearing them in their places,
in fact remaining permanently thereon if desired, and they can be made strong
enough to resist the weight of a second or third pole if such are used. Further-
more the device can be easily fixed by any ordinary labourer.
There is no

Improvements in Apparatus or Appliances to be used in Place of
Rope for Lashing Scaffolding Poles, Ledgers or the like.
We, JOSHUA GEORGE MILLS, of Grange Road, West Kirby, Builder, and PETER
CAMPBELL, of 6, Montgomery Terrace, Hoylake, Joiner, both in the County of
Chester, 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 :-
This invention has for its object an apparatus or appliance to be used in
place of rope for lashing scaffolding poles, ledgers, put logs, or for lashing any
two articles together in scaffolding, with a view to doing away with the accidents
which so frequently occur through faulty lashing, and through lashing ropes
breaking, which they are so liable to do when they get rotten through being left
out in all weathers.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Figure 1 is a general view of our device showing a scaffolding pole and ledger
secured together,
Figure 2 a view of the same device in elevation with the cross ledger in
section,
Figure 3 a view of the device for securing a pole and a plank together.
Referring to these figures, we provide a clip A or its equivalent, preferably
roughened inside or provided with teeth, and made in two halves so as to grasp
the pole B by the two ends of the clip being drawn forcibly together by nuts
and bolts. Pivoted to this clip A is another clip C of similar construction
adapted to grasp another pole, when it is required to superimpose scaffolding
poles one above the other, or to grasp a horizontal pole or ledger D. The two
clips being pivoted at E, enables the poles to be bound together at any required
angle, the pivot permitting this to be done.
It is obvious that instead of using a clip C it may take the form of a socket
adapted to hold one end of the ledger and fitted with a tightening device to
tighten the ledger in the socket. This socket may also be used to receive the
bottom of another pole when it is required to superimpose scaffolding poles one
above the other, and underneath the socket is a bracket or arm adapted to bear
against the side of the pole and strengthen the socket.
In action, a hinged clip is placed round each pole and closed, and fastened
thereto by screwing up the screw. When this is completed the ends of the
ledgers are placed in the sockets, also the ends of the superimposed poles if such
are required to be used, and the tightening device screwed up to keep them
tight. In this position the bracket rests against the pole and resists the strain on
the socket. Planks are then placed on the ledgers in the ordinary way.
Figure 3 shows the shape the device will take when articles of round and rectan-
gular shape in cross section have to be secured together.

special experience required, as there is in the case of erecting scaffolding with
rope lashing.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. An apparatus or appliance to be used in place of rope for lashing scaffolding
poles, ledgers or the like, which consists in a clip or its equivalent adapted to
grasp a scaffolding pole at any point in its length, and a second clip or socket
pivoted to the first clip and adapted to grasp another pole when it is required to
superimpose one or more scaffolding poles one above the other, or to grasp a hori-
zontal cross pole ledger, plank or other article, whereby two or more poles can be
securely bound together (either in parallel planes or at any required angle, sub-
stantially as described.
2. The improved apparatus or appliance for use in place of rope for lashing
scaffolding poles, ledgers put logs or the like, constructed, arranged and operat-
ing substantially as set forth.
