A latching arrangement is provided which comprises an engagement portion on the container and a latch element displaceably mounted on a cover element for co-operating latching engagement with the engagement portion. The latch element is displaceable in response to said pulling force prior to movement of the cover elements to permit release of engagement between the latch element and engagement portion.Type: GrantFiled: March 14, 1978Date of Patent: November 18, 1980Assignee: MacGregor International S.A.Inventor: George J. Leitch

Patent number: 4073239Abstract: A hatch cover having a locking mechanism comprising a single hand wheel with a shaft threaded to the cover for limited up and down movement as the hand wheel is turned. A locking strap is hinged on one side of the hatch cover, releasably locked on the other side and has an opening through which the shaft extends. The locking strap is confined between the hand wheel and a thrust washer attached to the shaft in such a fashion that rotation of the hand wheel in one direction produces contact between the locking strap and thrust washer to force the cover downwardly. Rotation in the other direction lifts the hatch cover to permit unlatching of the locking strap and access to the hopper.Type: GrantFiled: September 20, 1976Date of Patent: February 14, 1978Assignee: Apex Railway Products Co.Inventor: Franklin P. Adler

Patent number: 4022232Abstract: For protecting cargo in a ship's hold an inverted hatch tent is mounted between a cargo hatch cover and the hatch coaming to thereby define a concave liner below the hatch cover. The inverted hatch tent accoding to the instant invention therefore protects cargo from inevitable water leakage even with the hatch cover in place. Th instant liner further accommodates various hatch opening sizes through a plurality of gripper lines on the underside of a single liner. A further advantageous feature on the instant invention is the provision of a drain line at the apex of the inverted cover to communicate with a drain line which is passed within the hatch along the side wall and down to the ship's bilge.Type: GrantFiled: January 26, 1976Date of Patent: May 10, 1977Assignee: Retla Steamship CompanyInventors: David G. Ross, Jack Wybenga

Patent number: 4020778Abstract: A hatch cover for closing and sealing a hatch opening has radial latching arms connected at their inner ends to a rotatable arm-actuating hub on the bottom side of the cover at ball-and-socket connections and loosely connected to the cover near their outer ends. In one rotational position of the hub the arms overlap and apply clamping pressure to the rim of the hatch opening and in a second rotational position of the hub the arm-clamping pressure is released and the arms are retracted from the rim to enable removal of the cover from the opening. The hub rides on camming surfaces of the cover which are shaped so that as the hub rotates in a hatch-closing direction, the arms first extend over the rim of the opening and then pivot into clamping engagement with the rim about their loose connections to the cover, urging the cover through such connections into tight seated engagement with the rim.Type: GrantFiled: February 13, 1976Date of Patent: May 3, 1977Inventor: Robert W. Sutton

Patent number: 4021073Abstract: A lid for a vehicle roof opening has linkage hinging it to the roof structure accommodating tilting the lid upwardly in either of two directions, or elevating it bodily, for use of the opening to ventilate the vehicle, including provision for separating parts of the hinging linkage to permit swinging the lid fully open for use of the roof opening as an escape hatch. In a modification, the lid is hinged for tilting in only one direction to a ventilating position or swinging to the full open position in the same direction.Type: GrantFiled: March 18, 1976Date of Patent: May 3, 1977Inventor: Donald L. Manning

Patent number: RE29816Abstract: A lock hinge preferably, but not exclusively, for use with a hatch cover structure for a transportation vehicle. The lock hinge comprises a latch bracket and a base bracket. The base bracket is provided with a pivot bar. The latch bracket has a saddle member defining a hinge seat with a mouth opening for receiving at least a portion of the pivot bar therein. The latch bracket further is provided with a latch member having a lever end and a gate end. The latch member is interconnected to the saddle member by a flexible plate whereby the gate end is displaceably positioned adjacent the mouth opening of the hinge seat to retain the pivot bar captive in the hinge seat to interconnect both the latch and base brackets. When secured to a hatch cover, which normally closes the hatch opening in a wall of the vehicle, at least one lock hinge is secured on a respective one of a pair of opposed sides of the cover.Type: GrantFiled: November 21, 1977Date of Patent: October 31, 1978Assignee: IEC-Holden Ltd.Inventors: Robert B. Winsor, George Thomson
