Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 421 words
A container and vehicle in combination comprising: (a) a lower U shaped body; (b) a plurality of wheels supporting said body; (c) a plurality of conventional hydraulic cylinders attached to said body in a vertically disposed position; (d) a first upper U shaped member supported by said hydraulic cylinders such that only vertical motion of said first upper U shaped member is possible for raising and lowering the same; (e) a second upper U shaped member rotatably attached at the ends opposite the bight of the U to said first upper U shaped member; (f) a telescopic hydraulic cylinder attached between the bights of the upper "U" shaped members such that the bight of said second upper U shaped member may be urged away from the bight of said first upper U shaped member when said telescopic hydraulic cylinder is expanded for tilting the same; (g) a pair of stops attached to the top of said second upper U shaped member at a point near the end of the arms thereof and remote from the bight; (h) a container having an (1) upper U shaped frame having a width greater than the distance between the arms of said second upper U shaped member and diposed above the same when said upper "U" shaped members are in a lowered position, (2) a lower box structure attached to said frame having sidewalls, the outer sides of which are spaced apart a distance less than the distance between the arms of said U shaped member, and a bottom, open at one end and slanted at the other, and (3) a hinged door hanging within said open end for opening at the bottom when said container is tilted; (i) a first locking bar for insertion through rear registry holes in said body and said container transverse thereto holding said door closed, and (j) a second locking bar for insertion through front registry holes in said body and the front of said container, transverse thereto, Whereby said upper U shaped members may be lowered, said body may be backed toward said container such that said U shaped members receive said container with the hinged door facing outward, and said upper members may then be raised thereby supporting said container for transport and whereby when dumping is required said telescopic cylinder may be expanded while said upper members are in contact with said container causing tilting of the same and whereby said locking bars lock said container integral with said body lending ridigity to the entire structure.
Claim 2
Dependent Claim 421 words
A container and vehicle in combination comprising: (a) a lower U shaped body; (b) a plurality of wheels supporting said body; (c) a plurality of conventional hydraulic cylinders attached to said body in a vertically disposed position; (d) a first upper U shaped member supported by said hydraulic cylinders such that only vertical motion of said first upper U shaped member is possible for raising and lowering the same; (e) a second upper U shaped member rotatably attached at the ends opposite the bight of the U to said first upper U shaped member; (f) a telescopic hydraulic cylinder attached between the bights of the upper "U" shaped members such that the bight of said second upper U shaped member may be urged away from the bight of said first upper U shaped member when said telescopic hydraulic cylinder is expanded for tilting the same; (g) a pair of stops attached to the top of said second upper U shaped member at a point near the end of the arms thereof and remote from the bight; (h) a container having an (1) upper U shaped frame having a width greater than the distance between the arms of said second upper U shaped member and diposed above the same when said upper "U" shaped members are in a lowered position, (2) a lower box structure attached to said frame having sidewalls, the outer sides of which are spaced apart a distance less than the distance between the arms of said U shaped member, and a bottom, open at one end and slanted at the other, and (3) a hinged door hanging within said open end for opening at the bottom when said container is tilted; (i) a first locking bar for insertion through rear registry holes in said body and said container transverse thereto holding said door closed, and (j) a second locking bar for insertion through front registry holes in said body and the front of said container, transverse thereto, Whereby said upper U shaped members may be lowered, said body may be backed toward said container such that said U shaped members receive said container with the hinged door facing outward, and said upper members may then be raised thereby supporting said container for transport and whereby when dumping is required said telescopic cylinder may be expanded while said upper members are in contact with said container causing tilting of the same and whereby said locking bars lock said container integral with said body lending ridigity to the entire structure.
