According to a ?rst form of embodiment of the pres
ent invention applied to cover panels and hatches or like
openings the construction of which is of the character
described hereinabove, a hatch-cover (not shown) is
adapted to roll on the hatch-coaming surrounding the 25
hatchway. Either on the hatch-coaming proper, or on a
built-up member provided laterally thereto, the device de
scribed hereafter is provided.v
It may be assumed that this device is contiguous to
the hatch-coaming designated diagrammatically by the 30
reference numeral 200. In this hatch-coarning an ori?ce
201 is formed through which a bearing element 202 ex
Similarly,
the upper link 205 may be partly dispensed with, for it
is only suf?cient that the movement of link 209 allows
the upward and downward motion of the bearing element
by causing same to accomplish a certain rotation and to
hold same against motion when it bears on the stud 204.
As previously indicated, a crank handle 210a acting upon
the lower pivot 210 of link 209 may be provided for oper

member or element 202 is formed with a platform-like
209* having its opposite end pivoted on a ?xed point.
The operation of the device described hereinabove is
extremely simple. When the panels are in their open
position and must therefore be able to roll freely along
the edges of the hatchway, it is desirable that the stud
or roller 204 be raised or’at'least able to slide along the
guideway provided to this end on the hatch-coaming 200'.
By the way, it may be noted that the panels may be
carried by the same studs 204 since their sliding move
ments on the guideway can be promoted by lining the
latter with synthetic or other material 200'.
