This invention relates to a ?oating wall or
partition, that is, a wall not rigidly connected to
other walls and/or a ceiling and/or a ?oor, but
.on the contrary one in which slight relative
5 movement between the Wall and one or more sur
faces adjacent thereto is permitted.
Experience has demonstrated that with modern
buildings, storms involving wind pressures set up
vibration which is transmitted to all parts of
10 the structure. This is true likewise in buildings
having moving machinery or located above sub
ways, train sheds or the like. As a result of this
a great extent serve to mask their otherwise ap
parent purpose.
The invention further consists in the novel ar

which are in turn rigidly attached to the build
rangement, combination and construction of
parts more fully hereinafter described and shown
in the drawings.
In the drawings

The invention further contemplates that the
?oating wall shall be resiliently supported on the
floor or the like to permit dissipation of any
shocks which might otherwise be transmitted to
the wall.
The invention further contemplates the use of
decorative molding or angle irons which will to 10

The invention is not particularly concerned
with the material of which the wall or partition
is made. This may be of metal or wood lath
covered with plaster, partition tile of gypsum or
35 the like. wall board. gypsum lumber or Plank or
in'fact any material which is subject to cracking

A preferred embodiment of the invention con
sists in the use of angle irons or the like between
the rigid wall and/or ?oor and/or ceiling and the
floating wall or partition. It is desirable, of
course. that one dimension of the ?oating wall
be rigidly attached to something. and this rigid
dimension is usually the floor, that is, the ?oat
ing wall or partition may be rigidly connected to
the ?oor of the room. The sides and top of such
wall or partition are preferably enclosed between
such angle irons, which in turn are rigidly at
tached to rigid walls and/or the ceiling, the sides
and top of the floating wall or partition being
spaced from the other walls. This permits of a
sliding movement between the ?oating wall and
the rigid walls so that in case of building vibra
a wall 3 extends.
These walls for the purpose of illustration may
consist of elongated precast slabs of gypsum or
the like 5, the opposite edges of which are pro
vided with metal members 6 and 1 respectively,
tongued and grooved to provide a mating inter
lock.- This material is known in the trade as
Gypsum Plank. This construction material is as
made in varying lengths and may be out, sawed
and spliced together to ?t any desired space.
As shown in Fig. 5, it is desirable that the hori
zontal joints between units be staggered with re
gard to each other, that is, that the horizontal 45
joints between adjacent rows of units be out of
register with each other. This makes for a
stronger construction. While this form of ma
terial is shown as constituting a wall, yet obvi
ously the invention is not limited thereto as any 50
desired material may be used.
It will be apparent that the columns I and
their encasing material 2 constitute the rigid
portion of the building which will sway with the
building. It is desirable according to this inven
tion to permit relative movement between the
wall 3 and the encasing material 2 of the col

Reference to Fig. 4 will‘ show that the wall 3
is supported in a saddle 9 having lower flanges

'I claim:
1. In combination, a ?oating wall extending
between two side walls, a ceiling and a ?oor,
said wall being removably held by retaining
means rigidly connected to said ?oor, retaining
means rigidly secured to, the side walls and the
ceiling, the retaining means slidingly engaging 20
the ?oating wall, said ?oating wall consisting of
individual, building units, some of which'are of
less height than the height of the ?oating wall
and interlocked together along their ' vertical
edges by means oftongues and grooves, the hori- ,
?brous or rubbery nature and in fact of any
zontal joints between adjacent units being out of
material which will readily support the weight of
the wall 3 in a resilient manner.
As thus described the wall~3 is 'to all intents
30 and
purposes rigidly attached to the floor
although resiliently supported thereon.
the wall 3 is swung into the position shown
in the dotted lines and against angle. iron l6
attached to the ceiling H, a second angle iron I8
35 is af?xed to the ceiling, the irons l6 and I8
holding the top of the wall 3 in a ?oating man
ner between the two. It is to be noted that the
top of the wall 3 terminates short of the ceiling
ll so as to permit relative movement therebe
4.9 tween without disruption of the wall.
As shown in Fig. 4, the irons l6 and i8 may
be of an ornamental nature and provided with
a portion I9 which may be used as a picture
molding or the like. This overcomes any tend
ency of the use of such angle irons to destroy the
aesthetic effect in rooms in Which they'occur.
As shown. in Fig. 2>the saddle 9 may take vari
ous forms and another modi?cation is illustrated
there conforming substantially to the principle
recited in connection with Fig; 4.
In Fig. 2 a modi?ed form of angle iron for re
taining the top of the wall 3 in place is shown
to consist of a single piece of metal 20 having
deformed downwardly projecting portions 2| be
tween which the wall 3 is secured and outwardly
projecting ?anges 22 ‘secured to the ceiling as
by’ nails 23. Such a retaining means'is placed
upon the wall before erection, the wall pushed
into place and then the nails'23 driven into the
to be restricted only by the scope of the claims.
2. The combination of claim 1 in which the
tongues and grooves of the individual units are
of metal.
3. In combination, a ?oating wall extending
between two side walls, a ?oor and a ceiling, re
taining means rigidly?xed to the side walls/and
extending a substantial distance there along, re
taining means engaging said. ?oor, said» ?oating 2'
well being carried by said means, retaining
means between said ceiling and saidl?oating
wall, said ?oating wall being spaced from‘ the
side walls and ceiling, whereby said wall'is per
mitted movement relative tothe side walls, ?oor
and ceiling by sliding within the retaining means “
in which the wall consists of individual building
units tongued and grooved together along their
adjacent vertical edges. '
4. In combination,’ a ?oating wall extending
between. two vertical plane surfaces and two
horizontal plane surfaces, all substantially at
right‘ angles to the plane of the wall, the wall
terminating short of and being relatively mov
able with respect to three of said-plane surfaces,
retaining means attached to three of said planes,
the wall slidingly engaging said means, said wall
consisting of individual units interlocked to
gether along their vertical edges by means of
tongues and grooves, sov that when the four
planes are distorted with relation to'each other,
the distortion will not be communicated to the
?oating wall by reason of the sliding engage~
ment between the wall and the retaining‘means.
