Cover assembly for receptacle transporting vehicle

In combination:

• (A) an open top receptacle;
• (B) a mobile main frame having a supporting frame assembly for said receptacle associated therewith;
• said receptacle supporting frame assembly being swingable through a vertically disposed arc relative to the mobile main frame so as to rotate said receptacle from a transport position to a dumping position for discharging contents of the receptacle;
• and
• (C) a cover assembly associated with said receptacle comprising:
• (1) a lid member for selectively closing the top of said receptacle;
• (2) support means mounted on said supporting frame assembly for positioning said lid adjacent the top of said receptacle during said swingable frame movement;
• said support means comprising:
• (i) at least one elongated support arm having first and second ends with said first end of each support arm combined with said supporting frame assembly to provide for rotation of each arm about a common horizontal axis relative to said supporting frame assembly;
• and
• (ii) means for connecting said lid member to said second end of said arm whereby rotation of said arm provides for said independent rotatable movement of said lid;
• said connecting means comprising:
• (a) a collar member having a configuration corresponding to a portion of the perimeter of said lid member;
• (b) means for combining said collar member to said second end of said support arm;
• and
• (c) means for retaining said lid member portion in said collar whereby said collar is concurrently rotatable with said support arm to provide for said swingable movement to said lid;
• (3) pivot means for presenting rotatable movement to said lid, independent of said supporting frame assembly movement, from a receptacle closure position to an open position displaced from the top of said receptacle;
• and
• (4) drive means for controlling said rotatable movement of said lid whereby said lid is selectively rotatable between said closure and open positions.

A receptacle transporting vehicle comprising:

• (a) an open top receptacle;
• (b) a mobile main frame;
• (c) a dumping frame mounted for first pivotal movement with respect to said main frame;
• (d) first extensible means between said main frame and said dumping frame for effecting said first pivotal movement;
• (e) a scull frame having means thereon for supporting said receptacle during transport, said scull frame mounted for second pivotal movement relative to said dumping frame;
• (f) second extensible means between said scull frame and said dumping frame for effecting said second pivotal movement therebetween, said first and second pivotal movements presenting a range of positions to said receptacle from a normal transport through a vertically disposed arc to a dumping position for dumping the contents of said receptacle;
• (g) a lid member for selectively closing the top of said receptacle;
• (h) support means mounted to said scull frame for positioning said lid adjacent the top of said receptacle during said scull frame movement;
• (i) pivot means for presenting rotatable movement to said lid, independent of said scull frame movement, from a receptacle closure position to an open position displaced from the top of said receptacle;
• and
• (j) drive means movable with said scull frame for controlling said rotatable movement of said lid whereby said lid is selectively rotatable between said closure and open positions.

In a receptacle transporting vehicle adapted to selectively engage and retain a removable and open top receptacle for transporting and discharging material retained therein, the vehicle including a pivotal frame adapted to rotate said receptacle between a material transporting position and a material discharging position, the improvement comprising:

• (a) a lid member independent from said receptacle and mounted on said frame;
• said lid member being selectively positionable for covering relationship relative to said receptacle;
• and
• (b) drive means mounted on said frame and engageable with said lid member for selectively urging said lid member between a first position wherein said receptacle is covered and a second position wherein said lid is displaced from said receptacle allowing discharge of said material.
