Telescopic chute

An improved telescopic chute of the type comprising a plurality of chute segments, including an uppermost chute segment adapted to be attached to a discharge end of a bulk material handling machine, a lowermost chute segment and at least one intermediate chute segment located between said uppermost and lowermost chute segments, said chute segments having progressively increasing diameters from said uppermost to said lowermost segments to permit nesting of a superjacent segment within a subjacent segment wherein the improvement comprises:

• a yoke member surrounding said lowermost chute segment;
• sheave means associated with the yoke member adapted to be attached to a hoist mechanism of the material handling machine;
• attachment means for securing said yoke member to said lowermost chute segment whereby a bearing weight of the nested chute segments is carried by said yoke member;
• and
• wherein the lowermost chute segment includes a flange outwardly extending around an upper periphery thereof and positioned on an upper surface of said yoke member to transfer a bearing weight of said nested segments to said yoke member;
• said yoke member including a pair of sheave support posts upwardly extending on opposed sides of said yoke member, each of said support posts carrying a rotatable sheave wheel thereon adapted to operably engage a wire rope of the hoist mechanism of said material handling machine, said sheave wheels spaced a distance above the yoke member whereby a center of gravity of a nested plurality of chute segments is spaced below the sheave wheels.

• said lowermost chute segment having a peripheral flange outwardly extending at an upper end thereof;
• a yoke member surrounding said lowermost chute segment and attached to the peripheral flange thereof;
• and
• a pair of sheave support posts upwardly extending on opposed sides of said yoke member, each of said support posts carrying a rotatable sheave wheel thereon at a distance spaced above the yoke member, said sheave wheels adapted to operably engage a wire rope carried by a hoist mechanism on said material handling machine.
