The upper channel frames 4t include
upwardly-extending flanges 45 and downwardly
extending flanges 45 which define oppositely fac

downwardly-extending flanges 48 and 43.
An overhead track 50 carried by the ship super
structure by means of suitable hangers 5| sup
ports the folding door structures in suspended
relation by means of trolleys 52, 53, and 54, which
travel upon inwardly turned and spaced flanges

,
The second trolley 53 (Figs. 1 and 6) is located
immediately above the junction of the door units
35 and 31, >the latter of which arespaced along
their adjacent edges. A vertical post |02 is dis
posed between these adjacent edges. This post
which is somewhat similar to the post 80 is bolted
rigidly as indicated at |03 to the lower mid por
tion of the yoke plate 18 of the second or central
trolley 53 and is thus suspended from the latter.
Upper stud shafts |04 having lower heads |05
are rigidly mounted by screw-threading or other
wise in spaced relation in the plate 'i8 of the
second or central trolley 53, and they have bearing
relation respectively with blocks |05, the latter

The inner or first trolley 52 directly suspending
the door unit 35 has its yoke 14 connected to an
upright post 80 (Fig. 5) in which a plug 8| is
Welded for the purpose of carrying an upright
bolt 82 rigidly secured thereon and which rigidly
secures the yoke 14 to the post 80.
An upper stud shaft 04 having a lower head
85 is rigidly mounted by screw-threading or
otherwise in the yoke _plate 18 of the end trolley
52, and has a bearing mounting in a block 85,
the latter being rigidly secured by means of
screws 09 in the frame member 45 between its
flanges 45. This block is located at the upper
inner corner of the door unit 35.
The lower portion of the post 80 has a metal
bar 90 rigidly mounted thereon by means of suit
able fasteners 9| and projects horizontally below
and parallel to the plate 18. A stud shaft 02 of
screw form is threaded through the bar 90 in
axial vertical alignment with the upper stud shaft
84 and has an upper unthreaded bearing portion
94 which rotatably receives a lowerv block 95
mounted rigidly by means of screws 95between
the downwardly-extending flanges 40 of the lower
channel member 4|. The door unit 35 is thus
hinged'adiacent its rear edge upon the stud shafts
84 and 02 for pivotal movement relative to the
post 80 and about a vertical axis.

The lower end of the stud shaft 32 has a roller

displacement therefrom by means of a lower head.
tute a unitary support for the adjacent door units
and all of these are suspended primarily from the
trolley 53. Linear spacing of the upper rollers
10 and like spacing of the lower rollers |20 is
such thatthis unitary support is maintained in
predetermined relationship and held against
turning about a vertical axis while carrying the
hinge connections |04 and ||4 for pivotal action
of the door units 35 and 31 about vertical axes
adjacent their opposing edges.
The third or inner end trolley 54 (Fig. l0) is
constructed in substantially the same manner as
those previously described with the exception that
one horizontal endl portion of the yoke plate 13
is omitted, Therefore, reference characters em
ployed in defining corresponding elements of the
trolleys 52 and 53 are applied in the same man
ner to the trolley 54.
In this, arrangement an
upright support |30 for the opposed marginal
- portions of the door units 38 and 39 is sectional
and includes upright post sections |3| and |32
which are joined by a so-called piano hinge |34
along one side of the post for pivotal action about
a vertical axis. The hinge |34 is secured to the
sections |3| and |32 by means of bolts |33 pass
ing therethrough.
The yoke plate 18 of the trolley 54 is provided
with an integral downwardly-extending arm |35
