A NEW OR IMPROVED SCAFFOLD FASTENER
Year: 1885

page_text: I WILLIAM PARRY of N° 12 Caelleppa Bangor, North Wales Builders Engineer
do hereby declare the nature of my invention for A NEW OR IMPROVED SCAFFOLD
FASTENER to be as follows:-
The object of this invention is to afford a safe ready and effectual method of
securing scaffolding.
My improved scaffold fastner consists of a rigid or flexible clamp or collar either
hinged jointed or plain provided with two perforated tongues through which a
screw bolt having a suitable collar thereon is inserted-The perforation in one
tongue is screw threaded on the inside while that on the other is plain thus
allowing the clamp or collar to be readily adjusted to fit the pole or poles and
when so adjusted to be tightened up to any requisite pitch.
1. To provide for the pole or poles being kept rigid and upright a bracket is affixed
to the clamp or collar such bracket consists of a centre bar formed at bottom with
a curved arm terminating in a shoe that takes its bearing against the pole and; thus
assists in keeping the latter upright-The top of the bracket consists of two
uprights connected at the top by a cross bar secured by nuts having a screw
threaded hole therein The outer vertical arm has also a screw threaded hole
formed therein.
-
The two vertical arms together with the centre and cross bars form a recess to
receive the put lock which when placed therein is secured by a second screw bolt
which is inserted either in the outer vertical arm or in the cross bar or if preferred
two screw bolts may be employed one being inserted in the cross bar and the other
in the outer vertical arm thus giving greater security.

If desired the bracket may be dispensed with and only the clamp or collar
employed.

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:
The object of this invention is to afford a safe ready and effectual method of
securing scaffolding.
My improved scaffold fastener consists of a rigid or flexible clamp or collar. (1)
either hinged jointed or plain provided with two perforated tongues (2-2) through
which. a screw bolt (3) having a suitable collar (3x) thereon is inserted-The per-
foration in one tongue is screw threaded on the inside while that on the other is
plain thus allowing the clamp or collar to be readily adjusted to fit the pole or
poles and when so adjusted to be tightened up to any requisite pitch.
To provide for the pole or poles being kept rigid and upright a bracket (4) is
affixed to the clamp or collar such bracket consists of a centre bar (5) furnished at
bottom with a curved arm (6) terminating in a shoe (7) that takes its bearing
against the pole and thus assists in keeping the latter upright The top of the
bracket consists of two uprights (8) connected at the top by a cross bar (9) secured
by nuts (10) having a screw threaded hole therein-The outer vertical arm has
also a screw threaded hole formed therein.
The two vertical arms together with the centre and cross bars form a recess to
receive the put lock which when placed therein is secured by a second screw bolt (11)
which is inserted either in the outer vertical arm or in the cross bar or if preferred
two screw bolts may be employed one being inserted in the cross bar and the other
in the outer vertical arm thus giving greater security.
If desired the bracket may be dispensed with and only the clamp or collar
employed..
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A scaffold fastner constructed fitted and arranged substantially in the manner
herein before specified and shewn.
2. Dispensing with the bracket, and using the clamp or collar alone as herein-
before specified.
