PROVISIONAL SPECIFICATION.
An Improved Device for Connecting the Parts of Scaffolding and
other like Structures.
I, FRANCIS WELDON, of Erlimount, Earley, in the County of Berks, Colonel
in the Indian Staff Corps, do hereby declare the nature of this invention to be as
follows:-
:-
+
The main object of my invention is the construction of a device to be employed
in erecting scaffolding, in place of the rope lashings ordinarily used.
My said device consists of a short length of wire rope, or chain, furnished with
a loop or eye at each end. To one of the said loops I attach a double hook, the
ends of the hooks being bent downwards and sharpened to form spikes.
To connect a horizontal pole to a vertical pole in scaffolding, or other like
structure, the rope is placed round the vertical pole below the horizontal pole,
then brought round the latter and crossed on the vertical pole, the ends being then
brought round the said pole and united by entering the aforesaid double hook in
the loop, so that the spikes are .against the pole. These spikes entering the wood
are sufficient to retain the device in place, and the arrangement is such that the
greater the weight brought to bear upon the horizontal pole, the more rigid the
attachment becomes, as any downward strain increases the grip of the rope, and
slipping is impossible. At the same time the position of the horizontal pole can
be instantly adjusted by pressing up the lowermost part of the rope. This slackens
the whole arrangement and the short spikes being pulled out of the wood the
said horizontal pole and rope can be moved up and down as required, while
directly the weight is allowed to bear on the rope, the device again becomes
rigidly attached.
Although described in connection with a horizontal and vertical pole, it is
equally applicable for securing a diagonal to a vertical pole.
I do not confine myself to the use of the double hook above-described, as a
plate furnished with spikes and hooks for attachment to the loop, or other similar
device, may be employed, if preferred. Again in place of the said plate, or the
aforesaid double hook, I may connect the looped ends of the wire rope by means of
one or more thinner and consequently more flexible ropes or cords. The said
cord or cords are attached to the loops and wound tightly round the.upright post
or pole, to prevent any possibility of slipping, and are tied together or to the loops,
either before or after being wound round the post..

1, FRANCIS WELDON, of Erlimount, Earley, in the County of Berks, Colonel
in the Indian Staff Corps, 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:-

In the accompanying sheet of drawings :—
Fig. 1 is a view of my said improved device, and
Figs. 2 and 3 are views of modified forms of the same.
Figs. 4, 5 and 6 are elevations, from three different points of view, shewing the
application of the device to the erection of scaffolding.
Similar letters of reference denote similar parts throughout the drawing.
The device, as shewn in Figs. 1,.4, 5 and 6, consists of a short length of wire
rope A, furnished with a loop or eye B at each end. To one of the said loops,
I attach a double hook C, the ends of the hooks being bent downwards, and
sharpened to form spikes D.
To connect a horizontal pole E, to a vertical pole F, in scaffolding and other
like structure, by means of this device, the rope A is placed round the vertical
pole F, below the horizontal pole E, then brought round the latter, and crossed
on the back of the vertical pole at H, the ends being then brought round to the
front of the said pole, and united by entering the double hook Č, in the loop, so
that the spikes D, are against the pole. These spikes entering the wood are
sufficient to retain the device in place, and, as will be seen, the arrangement is
such, that the greater the weight brought to bear upon the horizontal pole, the
more rigid the attachment becomes, as any downward strain increases the grip of
the rope A, and slipping is impossible.
At the same time the position of the horizontal pole can be instantly adjusted by
pressing up the lowermost part of the rope. This slackens the whole arrangement,
and the short spikes D, being pulled out of the wood, the said horizontal pole and
rope can be moved up and down as required, while directly the weight is allowed
to bear on the rope, the device again becomes rigidly attached.
Although described and shown in connection with a horizontal and vertical
pole, the device is equally applicable for securing a diagonal to a vertical pole.
I do not confine myself to the use of the double hook C, above described, as a
plate J, Fig. 2, or other similar device furnished with spikes K, and hooks LL
for attachment to the loops B may be employed if preferred.
Again in place of the said plate J, or the aforesaid double hook C, I 'may
connect the looped ends B of the wire rope by means of one or more thinner, and
consequently more flexible ropes or cords M, Fig. 3. The said cord or the cords
are attached to the loops B and wound tightly round the upright post or pole, to
prevent any possibility of slipping, and are tied together on to the loops, either
before or after being wound round the post.
In place of wire rope, the main part A of the dévice may be formed of chain
if desired.
"
The strain of supporting the horizontal pole is not borne in any way by the
spikes in the hook or plate, or by the thin cords M, their object being merely to
prevent the slipping of the rope A on the vertical pole.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:-
1. A device for attaching the parts of scaffolding and other like structures
consisting of the combination of a short wire rope or chain having a loop or eye
at each end, and a spiked hook, spiked plate or small cords, substantially as set
forth.
2. A device for attaching the parts of scaffolding or other like structures con-
sisting of the combination of a short wire rope or chain A, having a loop or
eye B at each end, and a double hook C, with spiked ends D, substantially as set
.forth.
3. A device for attaching the parts of scaffolding or other like structures,
consisting of the combination of a short wire rope, or chain A, having a loop or
eye B at each end, and a plate J with hooks.L.L and spikes K, substantially as
