Tiltable material-receiving bin having actuated dumping floor

Claim 2

A material handling assembly comprising: a support; a material receiving bin normally resting on said support; a normally horizontal floor; hinge means attaching the floor to the bin for swinging movement of the floor relative to the bin to and from an inclined position; an upstanding frame on said support; pivot means spaced above the support and mounting the bin on the frame for swinging movement of the bin away from the support to a material dumping position; and power structure coupled with said floor and disposed for actuation by the bin as the latter is swung to the dumping position for forcibly swinging the floor to said inclined position in response to swinging of the bin to said dumping position, said floor extending obliquely across the bin when the same is in said inclined position for flow of material along the floor from said bin.

Claim 3

A material handling assembly as claimed in claim 1, said bin having a pair of opposed walLs, said hinge means being disposed adjacent the normally lower end of one of said walls, said pivot means being disposed adjacent the normally upper end of the other of said walls.

Claim 4

A material handling assembly as claimed in claim 2, said hinge means being at one end of the floor; and means guiding the opposite end of the floor along said other wall as the bin is swung to and from said dumping position.

Claim 5

A material handling assembly as claimed in claim 3, said floor being extensible between the hinge means and said guiding means as the floor swings to said inclined position.

Claim 6

A material handling assembly as claimed in claim 3, said floor having a pair of interconnected sections extensible between the hinge means and said guiding means as the floor swings to said inclined position.

Claim 7

A material handling assembly as claimed in claim 5, said sections being provided with articulating means interconnecting the same for relative swinging movement about an axis parallel with the axis of the hinge means.

Claim 8

A material handling assembly as claimed in claim 5, said sections being relatively telescoped.

Claim 9

A material handling assembly comprising: a support; a material receiving bin normally resting on said support, said bin having a pair of spaced, normally upright sidewalls and a normally horizontal wall; an upstanding frame on said support along one of said sidewalls; pivot means at the upper ends of the frame and said one sidewall and mounting the bin on the frame for swinging movement of the bin away from the support to a material dumping position with said sidewalls generally horizontal and overlying said support; hinge means at the normally lowermost end of the other of said sidewalls attaching the horizontal wall to the bin for swinging movement to and from an inclined position extending from said hinge means toward said upper end of said one sidewall when the bin is in said dumping position; and structure coupled with said horizontal wall for swinging the latter to said inclined position in response to swinging of the bin to said dumping position.

Claim 10

A material handling assembly comprising: a support; a material receiving bin normally resting on said support, said bin having a pair of spaced, normally upright sidewalls and a normally horizontal wall; an upstanding frame on said support along one of said sidewalls; pivot means at the upper ends of the frame and said one sidewall and mounting the bin on the frame for swinging movement of the bin away from the support to a material dumping position with said sidewalls generally horizontal and overlying said support; hinge means at the normally lowermost end of the other of said sidewalls attaching the horizontal wall to the bin for swinging movement to and from an inclined position extending from said hinge means toward said upper end of said one sidewall when the bin is in said dumping position; and structure coupled with said horizontal wall for swinging the latter to said inclined position in response to swinging of the bin to said dumping position.

Claim 11

A material handling assembly as claimed in claim 8, said structure including cable and pulley means interconnecting the bin, the horizontal wall and the support.

Claim 12

A material handling assembly as claimed in claim 9, said structure including pulley means on the bin and a cable having one end thereof attached to the horizontal wall and the opposite end thereof attached to said support with the cable trained over the pulley means intermediate said ends thereof.

Claim 13

A material handling assembly as claimed in claim 8; a normally upright panel within the bin across said one sidewall adjacent the lower end of the latter; an articulated joint between the floor and the panel; and means for guiding the panel toward said pivot means as the horizontal wall swings to said inclined position whereby the panel serves as an inclined floor extension for flow of material from the bin.

Claim 14

A material handling assembly as claimed in claim 8, said bin having a pair of spaced normally upright end walls interconnecting the sidewalls, the sidewalls and the end walls being normally perpendicular to the horizontal wall.

Claim 15

A material handling assembly as claimed in claim 8, said structure being provided with lost motion means for delaying the swinging of the horizontal wall about said hinge means as the bin swings away from the support.

Claim 16

A material handling assembly as claimed in claim 13, said lost motion means being interposed in the cable; and yieldable means maintaining the cable taut during said delay.
