As is generally known, piers, and particularly
those for large ocean-going steamships, are
equipped with large doors along their‘sides, the
arrangement being such that as many may be
5 ~' opened as desired for the loading and unloading
of the cargo, and likewise for passengers. Prac- '
tically all the piers of larger size are of double
deck or two-story construction, the passengers
ordinarily passing between the ship and piers on
10 the upper floor. It is also a fact that upon the
departure or arrival of a. steamer there is a large
assemblyof friends and relatives so that means
must be provided to keep such persons within
certain safety zones.
Heretofore it has been the practice to have
wooden guards or fences that are placed across
the door openings after the doors have been
opened. These fences are removable and there
l fore require storage-space, which is an important
20 item on piers.
'I'he object of the present invention is to pro
vide a door structure which in its specific char
views diagrammatic in their nature, showing the
different relations the door elements may be
caused to assume.v
The door structure and its operating means in its
general make-up, and save for the modifications 6
hereinafter explained in detail, correspond to the
disclosure in Letters Patent of the United States
granted to David H. Morgan, No. 1,789,189, Jan
uary 13, 1931, and therefore reference may be
had to that patent fo'r a more specific disclosure,
particularly'of the operating mechanism.
Using the same reference letters as appear in
that patent toÀ designate generally correspond
ing parts, the lower leaf ofv the door is shown at
A, and is adapted to register with theupper door
leaf B by a sliding movement accomplished
through the movement of the leaf A upwardly
behind the leaf B and guided by the members C
carried at opposite _sides of the leaf B. The up
per leaf B has a, hinge `mounting at D at the
top or lintel portion of the doorway, so that

25 of the door structure, thus making it possible
to open the door and yet leave'a guard that will
prevent persons passing'beyond a certain zone
and being in danger of falling through or from
the open doorway.V
Considering now generally the operating mech
anism, the same includes a pair ofglifting levers

n‘iay be in the form of a channel bar, and in the
channel thereof, is secured by screws 31 or other
suitable devices, a hand rail “that projects above
the bar I9. The lower bar 28 of the upper secfull "tion I6 may be a channel bar also, and when the
upper section is lowered, it will enclose this hand
fective one in that there is no dßIlger of its dis
placement by lateral pressure when it is‘in place

From the foregoing, it is thought that the con
struction, operation and many advantages of the
herein described invention will be apparent to
those skilled in the art without further descrip
tion, and it will be understood that various
changes in the size, shape, proportion and minor
details of construction may be resorted to with
out departing from the spirit or sacrificing any of
the advantages of the invention.
