Figure 5 is a detail perspective view, showing
portions of the elements constituting the walls,
ceiling, ?oor and roof, in assembled relation.
65 Figure-6 is a detail perspective view of the
walls of the building.
The walls, roof, ceiling, and partition elements
are of substantially the same construction, and
are formed of sheet metal comprising a body por
tion 24 of any desired length, one of the lateral
0
edges of the body being shaped to form an in
wardly opening substantially V shaped portion
25. A portion of the material constituting the
other lateral edge of the element is also shaped 55
2
2,109,655
to form an outwardly opening substantially V
shaped portion 26, and projecting from the outer
,
shaped portion 49, and in this manner the entire
wall face may be formed (see also Figure 2).
Within the hollow wall construction thus pro
vided, the uprights 22 ‘are arranged as shown
more clearly in Figure 4. The lower edge of the
edge of the portion 26 is a ?ange 21, which is dis
posed in substantial alinement with the lateral
edge 28 of the element 24. This portion 21 is
arranged at substantially right angles to the lowermost element 38 (see‘particularly Figures 1
portion 24 and is of any desired width, and the and 11) terminates short of the upper surface
free edge thereof is bent inwardly as at 29 to of the ?oor formed by the elements 24, and a
form a ?ange of any desired width.
‘ ?ller member 4| is provided which is itself formed
10
In constructing the ?oor and ceiling, a, series with an outwardly opening V shaped portion 42
of these elements are joined together, and a sec
ond series of the elements are inverted'and co
operate with the ?rst series to form the hollow
structure. In thus arranging the parts (see par
15 ticularly Figure 5) the ?ange 29 on one of the
elements rests against the under face of the por
tion 24 of another element, while the substan
tially V shaped portion 25 is seated within the
V shaped portion 26 of another of the elements,
and the parts are supported, to constitute the
?oor of the room or building, by means of an
angle iron 3ll_which is secured to the uprights 22.
Similarly, the structure which forms the ceiling
or root‘ is supported by means of an angle iron 3|
25 also secured to the uprights 22.
'
The upright walls are formed of similarly con
structed elements 24 which are arranged on the
outside of the building, and in this event the
elements are arranged on end, with the interlock
30 ing or interengaging portions 25-26 running
along one edge that engages over one of the
?ngers 43 on the ?ange 29 of the portion 21 of
the element 24, so as to substantially ?ll the
space between the lower edge of the element 38
and the floor. The lower edge of the element 4|
is bent backwardly and preferably upwardly as at
44 and then downwardly as at 45, the free edge
of the downwardly bent portion 45 being bent
back upon itself as at 46, and extends down below
the upper surface of the ?oor and between the 20
?oor element and the ?ange 29 of the element 24.
A molding member 41 provided along one edge
with a rearwardly and upwardly projecting ?ange
48, serves to provide a ?nish for the structure
at the ?oor line, the ?anged portion 48 extend
ing beneath the upwardly inclined portion 44' of
the element 4|. The upper edge of the element
41 may be bent back upon itself as at 49.
Thus it will be seen that with this structure
there will be provided a ?nish for the walls at 30
the ?oor line.
The corners of the building preferably encom
pass uprights 22, and are formed of a hollow

of is formed an ‘inwardly opening substantially
V shaped portion 42. These elements 38 consti
tute what might be termed a liner or the inner
face of the wall structure, and are arranged
60 so as to extend transversely of the uprights 22.
The upright elements 24 constituting the outer
face of the walls are provided along the ?anged
portion 29 with inwardly projecting lips or ?ngers
43 formed by cutting out portions of the ?ange
65 29 and de?ecting the cut out portions laterally,
thereby providing upwardly opening, seats or
hook shaped portions. Y
,
In assembling the elements 38, the outwardly
opening V shaped portion 40 is hooked over the
70 ?ngers 43 so as to enter the seats or pockets
formed by these ?ngers. This will cause the face
of the free edge of the V shaped portion 40 to
contact the face of the ?ange 29. The next ad
jacent element 39 is then placed in position by
75 seating the V shaped portion 42 into the V
an open space for a radiator or heating app»
ratus, and the wall 59 of which space is formed
by an upright member having a laterally project
ing ?ange 60 at its lower edge, the upper surface
of which ?ange is substantially ?ush with the
upper surface of the elements 24 forming a part
of the ?oor structure. The upper edge of the
member 59 is bent forwardly and preferably
slightly upwardly as at 6|, and the edge of the
portion 6| is bent to form an upwardly project
ing ?ange 62 which passes behind a downwardly
projecting ?ange 63 on the stool member 53. The 65
ends 64 of the member 59 are shaped in a similar
manner to form an open recess for a heating I
apparatus.
'
A ?ller member 65 is provided to ?ll the space
between the angle iron 39 and the rear wall 59 70
of the opening or space. This filler member 65
rests upon the ?ange 69 and is provided with a
downwardly projecting ?ange 66 which is adapted
to be inserted between the ?ange 30 and the
proximate portion of the adjacent ?oor element.

Arranged to slide within the window opening
are sashes 81-88, one preferably constituting a
storm sash, and intermediate the sashes 81-88,
may be provided a screen 88. The sashes 81-88
are guided in the open seats 5| of the adjacent
upright members, and spacers 10 shaped to form
a guideway ‘II intermediate its ends are provided
with laterally projecting ?anges 12-13 that co
operate respectively with the walls 14-15 of the
10 members 5| to guide the sashes 81—88 while the
intermediate member or screen 88 is adapted to
be moved in the seat or portion 1|.
Weight cords 18 are provided which pass over
suitable pulleys (not shown) and are connected
15 to the respective sashes and also to suitable
weights for ,counterbalancing the sashes, and
which weights move within the hollow wall
construction.
-

At the upper end of the wall, and adjacent the
20 ceiling there is provided a molding, provided with
a portion 11 of any desired width. One edge of
this portion is shaped to form a laterally‘ pro
jecting ?ange 18 that is adapted to engage over
a portion of the angle iron 3| and beneath the
25 adjacent surface of the elements constituting the
ceiling. The other edge of the element 11 is
being formed in the same manner as the wall
structure, maybe placed into position by insert
ing the ends of the partition into the space be
tween the adjacent elements 38. Tie or anchor
plates 98 may be provided, for securing the parti
tion in position.
If desired, suitable anchor clips 91 may be pro
vided for the uprights wherever necessary.
In the form of the invention shown in Figure 1,
the window sashes 81-48 and the screen 89 are
adapted to be raisedso as to slideinto the hollow
portion 98 (see Figure l) and the sashes being
counterbalanced, this movement may be readily
accomplished. Furthermore, suitable locking and
holding means for the window sashes (not shown)
may be provided.

In this form of the invention the window
sashes are provided with cross bars IOI between
which the window glass is arranged.
Provision is also made so that the window 25
sashes themselves may not only be raised but
shaped to form a downwardly inclined portion 19 ' lowered beyond the con?nes of the window frame
and a laterally projecting portion 80, the free opening, so as not only to provide a ventilating
edge of-which latter is bent downwardly asat means but to also provide a means whereby the
sashes may be lowered to facilitate cleaning the 30

face of the wall and overhangs the outer face of
the wall as at 88, the overhanging portion being
corrugated or suitably shaped to form a molding
or ?nish for the top of the wall.
‘
The walls of the building are preferably formed
of separate sections designated generally by the
reference numerals 89 and 90 in Figure 8, so that
55 the sections may be fabricated at the factory and
then shipped to the place where the building is
to be erected. To that end, the angle irons 3|
extend beyond the proximate edges of the ele
ments 38 as well as beyond the lateral edges of
60 the upright members 24 so as to form‘ a space 9|.
When the adjacent sections are secured together,
angle irons 92 are provided, and these angle irons
are supported in any suitable manner and ex
tend across the structure as shown more clearly
65 in Figure 4, upright channel irons 93 being pro
vided to support the angle irons 92, and to which
uprights the angle irons 92 are secured in any
I09 and III are adapted to be lowered.
_
The outer sash H1 is adapted to be moved
through an opening I I8 and the lower edge of the ,
sash H1 is‘ adapted to engage and rest against
the ?ange II2 to hold the lower sash closed.
When it is desired to lower either of the sashes
I09--I I1, the former is moved laterally outward
to disengage the shoulder IIO, and the latter is
moved laterally inwardly to disengage the ?ange
“2.
These sashes I09 and H1 move upon suitable
guides II9—I20, and the screen I2I also moves
on guides I22 so that they may be raised. The
screen I2I, however, is not adapted to be lowered
‘below the window sill.
Obviously, the sashes are counterbalanced by
weights I23 which move in a suitable casing I24
formed in the sides of’the window frame I02.
The casing into which thesashes are adapted
to be lowered is hollow, and outlet openings. I25
are provided as a means for draining the casing
erally by the reference numeral 95 in Figure 4,
in the event that water should ?nd its way there
into from the outside of the building.
The inner wall ill of the casing H8 is shaped
to form the stool I28 of the window sill and the
edge of this member I28 is bent downwardly as
are inserted so as to divide the structure into
rooms. Wherever a partition is to be employed
a ?nish adjacent the face of the adjacent ele
suitable manner.

~
The space 94 thus provided constitutes a space
70 in which the ends of a partition designated gen
the proximate ends of adjacent elements 38 ter
75 minate short of each other and the partitions,
at I21 and then back upon itself as at I28 to form ment 38.
_
.
In the form of the invention shown in Figures
4
2,109,865
12 and 13, there is disclosed a means whereby
the wall structures may be formed so that the
wall sections will not only be superposed but will
break joint with each other to simulate a stone
or brick surface, and in that event the elements
themselves are constructed of a smaller size.
The inner and outer surfaces of these elements
in this construction are formed of sections simi
lar in construction to the sections 38 so that
10 sections in both the inner and outer faces of the
wall run in the same direction. That is, the
length of each of the elements is disposed hori
zontally.
.
To that end there is provided any suitable
number of uprights I28 of channel formation se
cured together in any suitable manner, prefer
ably “at their tops and bottoms by connecting
members I30, and the channel uprights I29 areso
arranged that the outer faces of the side mem
20 bers of the channels will be disposed adjacent the
inner and outer faces of the wall structure.
Each of the side walls of the channels I29 is pro
vided with cut out portions I3I-I32 that are
between the wall sections may be dispensed with.
To that end an angle iron 3|” may be secured to
the ?ange 29 of the portion 21 of the element
24, in any suitable manner such as by means
of bolts, rivets, or may be spot welded, and the
?ange portion 40 of the sections” constituting
the inner wall may engage and rest thereupon.
This structure also serves as a means for rein
forcing and bracing the elements 24. Obviously,
any number of these angle irons II" may be em
ployed and arranged in any suitable position with
respect to each other.
In Figure 17 the numeral I39 designates col
umns or uprights corresponding to the uprights
22, and to one face of the uprights I33 angle irons 15
3Ib may be secured by suitable fastening devices
such as bolts or rivets 3|”. A molding “I is
shaped to engage and rest upon the ?ange of the
angleiron and is shaped to form an upwardly
opening channel or hook shaped portion I42 for 20
the reception of the picture hook.
The molding III is shaped to form an offset
portion providing a space I43 and the back of the
hook shaped portion I 42 overhangs and is spaced
