SLIDABLE PARTITION
Herbert H. Stevens, Jr., Lynn, Mass.
Application May 29, 1937, Serial No. 145,471
6 Claims.
This invention relates to building constructions
and more particularly to a movable wall structure
for dividing space in any building, such as a
dwelling, o?ice building, or factory, and may in
5 fact be used to divide space horizontally as well
as vertically.
It is an object of the present invention to pro
vide a movable wall structure which may be
quickly and conveniently moved into a position to
l0 divide a space, such as a floor space and form
a neat appearing continuous wall. The wall
structure may be made of any suitable material,
metal, wood, glass or otherwise, and may be
painted, decorated, or even insulated, as desired.
15 My construction is particularly adaptable to
modern dwellings in providing great ?exibility
cally from the floor I0 and is de?ned by a lower
substantially rectangular frame I2 and an upper
substantially rectangular frame I3. The lower
frame I2 is preferably imbedded in and substan
tially‘?ush with the surface of the floor II], but I
may be disposed on top of the floor, if desired.
Magazine I I may also be journaled in the ?oor and
ceiling to pivot in any direction, with correspond
ing channels or guideways for the wall panels.
Likewise magazine II may be made movable 10
laterally in any direction to enlarge or decrease
room size, by the use of suitable fastenings. The
upper frame I3 is suitably secured to the ceiling
(not shown) of the room. The lowerframe I2 is
provided with a groove or passage I6 communi
cating with a guideway or channel I1, the upper
of floor space and of room arrangement, and the
wall structure may be kept out of the way in at
tractive magazines when not in use. Thus addi
tional“ rooms may be provided, and the size of
existing rooms changed, as desired, at very little

‘turned ?anges I8 lying flush with and secured to
