Abstract:
1. In combination: a wheeled frame having a forward end, a rearward end, a first side and a second side; a side dump body movably mounted on said wheeled frame and having a rearward end, a forward end, a first side, a second side and an open upper end; said side dump body including a bottom wall portion, first and second side wall portions extending upwardly from said bottom wall portion, a forward end wall, and a rearward end wall; each of said first and second side wall portions of said side dump body having forward and rearward ends and an upper end; each of said forward and rearward end walls of said side dump body having first and second ends and an upper end; said side dump body being pivotally movable with respect to said wheeled frame so as to be able to dump contents thereof towards said first side or said second side of said wheeled frame; a wall extension apparatus movably positioned on said upper ends of said walls of said side dump body; said wall extension apparatus including: (a) an upstanding first side wall member having an upper end, a lower end, a forward end and a rearward end, (b) an upstanding second side wall member having an upper end, a lower end, a forward end and a rearward end, (c) a first upstanding forward wall member having an upper end, a lower end, an outer end and an inner end, (d) a second upstanding forward wall member having an upper end, a lower end, an outer end and an inner end, (e) a first upstanding rearward wall member having an upper end, a lower end, an outer end and an inner end, and (f) a second upstanding rearward wall member having an upper end, a lower end, an outer end and inner end; said first and second forward wall members of said wall extension apparatus extending inwardly towards one another from said forward ends of said first and second side wall members respectively with the inner ends thereof overlapping one another; said first and second rearward wall members of said wall extension apparatus extending inwardly towards one another from said rearward ends of said first and second side wall members respectively with the inner ends thereof overlapping one another; said lower inner ends of said first forward wall member and said second forward wall members of said wall extension apparatus being hingedly secured to said forward end wall of said side dump body about a horizontal axis; said lower inner ends of said first rearward wall member and said second rearward wall member of said wall extension apparatus being hingedly secured to said rearward end wall of said side dump body about a horizontal axis; said upper outer ends of said first and second forward wall members of said wall extension apparatus being hingedly secured to said upper forward ends of said first and second side wall members respectively; said upper outer ends of said first and second rearward wall members of said wall extension apparatus being hingedly secured to said upper rearward ends of said first and second side wall members respectively; said first forward wall member, said first side wall member and said first rearward wall member of said wall extension apparatus being selectively movable with respect to said side dump body between a transport position and a first side dumping position; said lower ends of said first forward wall member, said first side wall member and said first rearward wall member of said wall extension apparatus being in engagement with said upper ends of said forward end wall, said first side wall portion and said rearward end wall of said side dump body when said wall members are in their transport position; said lower end of said first side wall member of said wall extension apparatus being spaced from said upper end of said first side wall portion of said side dump body when said wall members are in their first side dumping position; said second forward wall member, said second side wall member and said second rearward wall member of said wall extension apparatus being selectively movable with respect to said side dump body between a transport position and a second side dumping position; said lower ends of said second forward wall member, said second side wall member and said second rearward wall member of said wall extension apparatus being in engagement with said upper ends of said forward end wall, said second side wall and said rearward wall of said side dump body when said wall members are in their transport position; said lower end of second side wall member of said wall extension apparatus being spaced from said upper end of said second side wall of said side dump body when said wall members are in their second side dumping position; said lower outer ends of said first forward wall member, said second forward wall member; said first rearward wall member and said second rearward wall member being selectively removably secured to said forward wall and said rearward wall of said side dump body respectively; said wall extension apparatus including structure which causes said lower end of said first side wall member of said wall extension apparatus to move out of engagement with said upper end of said first side wall portion of said side dump body when said wall extension apparatus is moved from its said transport position to its said first side dumping position and said side dump body is pivotally moved to dump the contents thereof from said first side of said wheeled frame and which causes said lower end of said second side wall member of said wall extension apparatus to move out of engagement with said upper end of said second side wall portion of said side dump body when said wall extension apparatus is moved from its said transport position to its said second side dumping position and said side dump body is pivotally moved to dump the contents thereof from said second side of said wheeled frame.
