PROVISIONAL SPECIFICATION.
Improvements in and relating to Scaffolding.
We, JOHN WALTER FLOWER and ROBERT JOHN COUSINS, trading as
Flower & Cousins, of Spring Head Works, Fontmell Magna, Shaftesbury, in the
County of Dorsetshire, Engineers, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to an improved device for fixing together the poles for
scaffolding and the like, and it consists of a chain adapted to be passed around the
poles after the manner of the ropes now generally used and provided with a device
whereby it can be drawn up taut, the object being to facilitate the fixing together
of scaffold poles and the like and to render their fixture more perfect and less
liable to work loose.
Our device consists of a length of any suitable type of chain to one end of which
is connected a single bar link the other end of which is pivotted to a small drum
near the periphery thereof, the said drum being provided with a slot for the said
link to work in. This drum has central bosses on each side forming bearing studs
on which it rotates the said studs taking a bearing on a slotted plate suitably
shaped to take a bearing aganist one of the scaffold poles. This slotted plate is
also provided with a hole or recess for the other end of the chain to pass through
and also with a transverse hole to receive a pin for locking the chain to the said
plate.
The drum has a series of transverse holes near its periphery which coincide with
a hole in the slotted plate which receives a pin adapted to lock the drum to the
said plate in any position.
In use the chain is passed around the poles of the scaffold after the manner of
the ropes now generally used, the slotted plate being held up against one of the
said poles. The free end of the chain is then passed through the hole or recess in
the slotted plate adapted to receive it and after being drawn up as tight as possible
is made fast thereto by means of the transverse pin hereinbefore referred to. The
drum is then operated by means of a suitably shaped lever carrying a pin adapted
to engage with one of the transverse holes in it until the chain is drawn up as taut
as possible when it is made fast to the slotted plate carrying it by means of the
transverse pin hereinhefore referred to.

COMPLETE SPECIFICATION.
Improvements in and relating to Scaffolding.
We, JOHN WALTER FLOWER and ROBERT JOHN COUSINS, trading as
Flower & Cousins, of Spring Head Works Fontmell Magna, Shaftesbury, in the
O County of Dorsetshire, Engineers, 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 :-
Our invention relates to an improved device for fixing together the poles for

page_text: scaffolding and the like, and it consists of a chain adapted to be passed around the
poles after the manner of the ropes now generally used and provided with a device
whereby it can be drawn up taut, the object being to facilitate the fixing together
of scaffold poles and the like and to render their fixture more perfect and less
liable to work loose.
We attain this end in the manner shown by the accompanying drawing in
which :-
Figure 1 is a view in side elevation showing the application of our inventio 1.
Figures 2 & 3 are views in side elevation and plan respectively-on an enlarged
scale of the tightening device, and
Figures 4 & 5 are broken views of the lever for actuating the tightening device.
Throughout the views similar parts are marked with like letters of reference.
Our device consists essentially of a length of any suitable type of chain A to
one end of which is connected a single bar link B which is pivotted at its other
end to a small drum C near the periphery thereof, the said drum being provided
with a circumferential slot e for the said link to work in. The drum C has central
bosses c', c', on each side forming bearing studs on which it rotates, the said studs
taking a bearing in a recess d in a slotted plate D suitably shaped to take a
bearing against one of the scaffold poles X. The slotted plate D is also provided
with a hole or recess d' for the other end of the chain A to pass through and also with
a transverse hole to receive a pin E for locking the chain to the said plate.
The drum C has a series of transverse holes c³, 3, etc. near its periphery which
coincide with a hole in the plate D which carries a pin F adapted to lock the drum
to the said plate.
In use the chain A is passed around the poles X, X, of the scaffold after the
manner of the ropes now generally used, the plate D being held up against one of
the said poles. The free end of the chain is then passed through the hole or recess d
in the plate D and after being drawn up as tight as possible is made fast thereto
by means of the transverse pin E. The drum C is then operated by means of a
suitably shaped lever such as Z which carries a pin z adapted to engage with one
of the transverse holes ², c², etc. in it until the chain is drawn up as taut as possible,
when the drum is locked to the plate D by means of the transverse pin F.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the accom-
panying drawing, but that we hold ourselves at liberty to make such changes and
alterations as fairly fall within the spirit and scope of our invention.
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. The improvements in and relating to scaffolding substantially as hereinbefore
described and illustrated by the accompanying drawing.
2. A device for fixing together scaffold poles consisting essentially of the chain A
and link B, of the drum C, of the plate D and of the locking pins E and F, as
set forth.
