similarly secured to the outer sides of the
front bars of the side panels, as described.
The plates 15 have their outer portions
bent outwardly or off-set to a slight degree
5 from the portion which engages the side pan-
els, as shown at 16, thereby preventing the
ends of the upper movable panels of the sec-
tions from binding against the inner sides of
the plates. Secured to the inner surface of
1o the end pieces of the upper movable panels 7
are right angular guide plates 17 which en-
gage the inner surface of the front end bars
of the side panels, as shown in Fig. 7 of the.
drawings, and in the plates 17 adjacent to
15 their outer edges is pivotally mounted one or
more guide rollers 18 which are preferably
provided with V-shaped bearing edges which
are adapted to fit and to travel in similarly
shaped grooves 19 formed in the inner edges
20 of the outer end bars of the side panels.
In addition to the rollers 18 there is also
preferably provided additional guide rollers
20 which are arranged in suitable recesses or
grooves 21 formed in the inner side of the
25 end bars of the movable panels 7 and said
rollers are revolubly mounted on suitable
bearing screws 22 which are arranged in the
end bars of the panels. The rollers 20 are
adapted to bear against the outer edge of the
30 front end bars of the side panels 3, as is
clearly shown in Fig. 7 of the drawings. By
means of the rollers 18 and 20, the ends of
the movable panels are held in position and
have a free sliding or anti frictional engage-
35 ment with the front end bars of the side pan-
els. The V-shaped edges of the rollers 18
which engage the V-shaped grooves in the
end bars of the side panels prevents any pos-
sible lateral or endwise movement of the
40 front movable panels 7.
In Figs. 8 and 9 of the drawings, is shown
a modified construction of sliding engage-
ment between the movable panels 7 and the
outer ends of the side panels 3. In the form
45 shown in Fig. 8, the ends of the movable
panels 7 have secured to their inner sides
guide plates 23. one edge of each of which is
bent at. right angles in one direction to form
panel attaching members 24, while the op-
50 polite edges of the plates 23 are bent at right
angles in the opposite direction to form
guide flanges 25 which are adapted to engage
the inner edges of the end bars of the side
panels whereby said upper movable front
5 panels are slidably held in engagemient wils
the ends of the side panels.
In Fig. 9 of the drawings, is shown a sec-
tional view through the adjacent front end
bars of the inner side panels of the sections.
60 The adjacent side panels of the two sections
of the case, when brought together to form
a double case, are spaced a suitable distance
apart by a spacing strip 26 and said side
panels of the sections are preferably se-
65 cured together by suitable screws or bolts27 which are inserted through the inner por-
tions of the bars forming the frame of the
side panels and through the spacing strip
2t, as shown in Fig. 9.
The stationary top panels of the sections 70
of the case are secured to the upper bars of
the end panels by spacing plates 28 which
are constructed and arranged in the same
manner as the plates 15 to provide a space
between said stationary top panels and the 75
upper edges of the side panels to receive the
movable panels 1.4 when the latter are drawn
back to open the case. The movable panels
14 are provided with guide plates 20 which
engage the zipper bars of the side panels of so
the sections and may be provided with upper
and lower guide rollers 30 and 31 arranged.
in the same manner as the rollers 1 and
20 of the front movable panels 7. or said
tipper movable panels may be provided sim- s5
ply with the angularly bent guide plates,
as shown in Figs. S aid 0 of the drawings.
In order to open or close the top and front
movable panels of the sections, we prefer-
ably provide a. suitable operating mechanism 90
comprising bell-crank operating levers 32
which are pivotally mounted on the inner
sides of the vertical parting strips of the
side panels of the sections adjacent to the
underside of the partition or shelf 11 and 95
the upper member of the levers projects up-
warcdly through suitable slots or notches 33
formed in the ends of the partition and are
pivotally connected at their upper ends to
push bars 34, which are pivotally connected 100
at their outer ends to the guide plates 209 of
the upper movable panels of the sections
whereby said panels are moved to an open
or closed position. The push bars 34 are
preferably formed in adjistai)le sections, 105
'the inner sections to which the upper ends
of the bell crank levers are connected, being
il the f(1111 of bolts 35 which have screw
threaded engagement with right angularly
formed lus 3 on the innuer ends of the 11.0
outer sections of the bars whereby the bars
may be lengthened or shortened to compen-
sate for the wear or sagging of the parts, 5(
that the panels may always be brought to
the proper position. The inner ends af the 115
bolt 35 are preferably provided with hifur-
cated heads 37 in which are pivotally se-
cured the upper ends of the bell crank le-
vers. On each of the bolts 35 is arranoged a
jam nut 38 which, when the bolts are in 120
proper adjusted position, are screwed into
tight engagement with the lug 30. thus se-
curing the bolt.
Pivotally connected at their upper ends
to the guide plates 17 or 2) of the front 125
movable panels of the sections are push
bars 30 which are constructed in the same
manner as te push bars 34 and are pivot-
a1ly connected at their lower ends to operat-
ing levers 40, the rear ends of which are 1300i
