Abstract
An apparatus for securing a hinged lid which covers an opening in the top of a rail wagon when it is in a closed position. The apparatus includes a rod rotatably mounted to the top of the wagon along at least part of a free side of the lid opposite or adjacent a hinged side of the lid. An arm is mounted to such rod which bears on the lid and thereby secures the lid in such closed position. There is a rotation device for rotating the rod. The rotation device is operable to rotate the rod and thereby rotate the arm away from the lid so that the lid may be opened.
Claims37
An apparatus for securing a hinged lid which covers an opening in the top of a rail wagon when in a closed position, said apparatus including:
- a rod rotatably mounted to the top of the wagon along at least part of a free side of said lid opposite or adjacent a hinged side of said lid;
- an arm mounted to said rod, said arm bearing on said lid to secure said lid in said closed position;
- and
- rotation means for rotating said rod, wherein said rotation means is operable to rotate said rod to thereby rotate said arm away from said lid whereafter said lid may be opened.
An apparatus for opening a hinged lid from a closed position in which said lid covers an opening in a top of a rail wagon, said apparatus including:
- a cam attached to said lid, said cam having an cut-out section;
- and
- an opening cylinder having a piston, the free end of the piston being mounted to the cam so that it can move within the cut-out section of said cam, the opening cylinder being operable to open said lid, during initial opening of the lid, the free end of the piston abutting the end of the cut-out section nearest the cylinder whereby operation of the cylinder pulls the lid up so that it rotates around the hinge until said lid reaches a point at which gravity causes further opening of said lid, whereafter said cut-out section of said cam allows said cam to move relative to said free end to a fully opened position.
An Apparatus for opening a hinged lid from a closed position and securing said hinged lid in said closed position in which said lid covers an opening in a top of a rail wagon,
- said apparatus including:
- a rod rotatable mounted to the top of the wagon along at least part of a free side of said lid opposite or adjacent a hinged side of said lid;
- an arm mounted to said rod, said arm bearing on said lid to secure said lid in said closed position;
- rotation means for rotating said rod, wherein said rotation means is operable to rotate said rod to thereby rotate said arm away from said lid whereafter said lid may be opened;
- a cam attached to said lid, said cam having a cut-out section;
- and
- an opening cylinder having a piston, the free end of the piston being mounted to the cam so that it can move within the cut-out section of said cam, the opening cylinder being operable to open said lid, during initial opening of the lid, the free end of the piston abutting the end of the cut-out section nearest the cylinder whereby operation of the cylinder pulls the lid up so that it rotates around the hinge until said lid reaches a point at which gravity causes further opening of said lid, whereafter said cut-out section of said cam allows said cam to move relative to said free end to a fully opened position.
An apparatus for opening a door slidably mounted to cover an opening at a bottom of a rail wagon when said door is in a closed position, the apparatus including,
- an opening cylinder having a piston, the free end of the piston being connected to the door so that operation of the opening cylinder can slide the door from said closed position to an open position.
An automatic system for opening a hinged lid and a slidable door from a closed position in which said hinged lid covers an opening in a top of a rail wagon and said door covers an opening located at a bottom of the rail wagon, said system including:
- (a) a first apparatus having a first opening cylinder with a piston, the free end of the first piston being connected to said door;
- and
- (c) a second apparatus including:
- a cam attached to said lid, said cam having a cut-out section;
- and
- an opening cylinder having a piston, the free end of the piston being mounted to the cam so that it can move within the cut out section of said cam;
- and
- the system being characterised in that during initial opening of the lid, the free end of the piston abuts the end of the cut-out section nearest the opening cylinder such that operation of the cylinder pulls the lid up so that it rotates about a hinge until said lid reaches a point at which gravity causes further opening of said lid, whereafter said cut-out section of said cam allows said cam to move relative to said free end of the opening piston so that the lid moves to a fully opened position, and the system being further characterised in that said first and second opening cylinders are operable to open said door and lid respectively.
