STAGING
Arístides Kakides, Haverhill, Mass.
Application May 24, 1938, Serial No. 209,688
3 Claims. (Cl. 304-11)
This invention relates to a form of staging brackets I0 each of which comprises a building
which is primarily designed for use by painters engaging portion II and a platform supporting
while painting the sides of a building, but which portion I2 which extends at right angles there
is adapted for use for other purposes. .
In Massachusetts, and possibly other States,
strict laws are in force as the use of stagings
and strict inspection is required before permits to
use are granted, the use of certain types of sus
pended stagings being prohibited. Stagings which
are built up from the ground are permitted but
are usually expensive.
The objects of my invention are to provide a
form. of staging which may be easily erected, is
rigidly supported on the ground without in any
- way being attached to the building in connection
from and is rigidly connected thereto by fasten
ing means (notshown) at the junction thereof' Ul
and by two pairs of braces I3 and I4 which ex
tend obliquely from one to the other. While
these braces may be secured to the side edges of
the portions II and I2, ribs I5 and I6 are pref
erably secured to the middle portions thereof and
the ends of said braces are secured to said ribs,
said braces being thereby spaced apart to pro
vide a socket between said braces and between
the surfaces of said ribs I5, IIì, which meet at
right angles in a transverse line, and in which
with which it is used, which is readily adjustable . an end of a brace I8 is adapted to be inserted, as
in height within the limits of an ordinary dwelling will be explained. A transversely extending foot
house, which is comparatively inexpensive to con
piece 20 is secured to the engaging portion I5 at
struct, which provides a rigid and perfectly safe the junction thereof with portion I2, and a simi
support for men who may work on it, and which lar foot piece 2l is secured to portion I I adjacent 20
will pass inspection so that its use will be per
mitted under the law.
I accomplish these objects by providing a pair
of right angular shaped brackets, each of which
is supported against the side of a building by an
adjustable brace which at one end engages the
bracket at the apex of the angle between a plat
form supporting portion and a building engaging
portion of the bracket, and, at the opposite end,
is fixed in the ground, and by providing a rigid
platform which is adapted to be supported on the
supporting portions of the brackets and to be
clamped thereto, and means being provided
whereby the platform may be raised and lowered
while suspended from a pair of ladders.
For a more complete disclosure of my invention
reference is now made to the following specifica
tion, in connection with accompanying drawings
in which
Fig. 1 is a front elevation showing the appli
cation of a staging embodying my invention to a
building.
-
Figs. 2 and 3 are detail front and side views of
one of the brackets which I employ.
Fig. 4 is a side elevation of the construction
shown in Fig. l.

Fig. 5 is a detail top plan view of a portion of
one of the brackets.
Fig. 6 is a detail view of a portion of one of
the braces.
Y
Fig. 7 is a detail view of a portion of the plat

Fig. 8 is a detail view of the ground engaging
end of one of the braces.
According to my invention I provide a pair of
55
its opposite end, the piece 2|> preferably having
a pair of friction rolls 22 mounted thereon.
Each brace I8 has at one end a somewhat
wedge shaped portion I9 of substantial width,
which is adapted to engage the bottom of the 25
socket along the transversepline at the apex of
the angle between the ribs I5, I6, and the op
posite end ofthe brace has' a sharp metal exten
sion 24 secured thereto, which is adapted to be
inserted in the ground to hold the brace securely
in position. The brace I8 is also preferably made
adjustable in length by any suitable means, the
means shown comprising a pair of clips 25 which
permit the two sections of which the brace is
composed to be telescoped and a bolt 25 to hold 35
them in adjusted position. The braces I8 are
straight and rigid, so that they will not buckle
1n use.
A platform 28, which preferably consists of
a single stout plank, is provided, which is adapted 40
to be placed on the portions I2 of the brackets
and to be clamped thereon by clips 29 and 30, the
clip 29 being fixed at the outer end of portion I2
and the clip 3û being adjustable, so that, after
the platform has been placed in position on the
brackets with one edge against the clips 2S, the
clips 30 may be adjusted against the opposite
edge, and as the ends of the clips have a right
angulariend portion which engage the top side
of the platform, the latter will be Securely held
on the brackets.
To provide a convenient means for placing the
platform in position and for supporting it while
adjustments are being made, two ladders 32 are
placed against the building close to the positions

in which the brackets are held, as shown in Fig.
1. A pulley 33 is attached to the top portion of
each ladder and a rope 34 is passed over each
pulley and provided with two end portions 35 to
which hooks 36 are attached. Staples 31 are
secured in each edge of the platform with which
the hooks 36 are engaged, as shown in Fig. '1, so
that the platform may be suspended from the
rope 34 and may be readily raised and lowered
untied to permit this, or, if desired, the clips 30
may be disengaged from the platform, so that the
latter will be supported by the ropes, while the
brackets are lowered and then it may be lowered
into position. If greater adjustment is desired
the braces I8 may be lengthened or shortenedas
will be obvious. As all the strain on the braces
I8 is lengthwise, they do not need to be par
ticularly heavy, as it is only necessary that they
be strong enough to prevent buckling.
