Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
Material-handling apparatus for lifting barrels, cans, or the like comprising a frame, a power lift mechanism including a boom and can-engaging means connected to one end of said boom, means supporting said boom from said frame for universal directional movement, said support means comprising a support plate fixed to said frame, a turntable pivotally mounted on said plate, guide means comprising spaced tracks mounted on said turntable, extension means comprising spaced members mounted within said tracks for longitudinal movement relative thereto, said boom being pivotally supported between said spaced members, a first hydraulic cylinder having one end connected to said guide means and its other end connected to said extension means for moving said extension means in said guide means, a second hydraulic cylinder connected between said extension means and said boom to pivot said boom vertically, means supporting said second hydraulic cylinder from said spaced members including a pair of upright plates between which said second hydraulic cylinder is positioned, a pair of bars extending from the forward end of said members upwardly to said upright plates, whereby said bars and said upright plates form a guide channel for said boom as it is pivoted vertically upon actuation of said second cylinder, and actuating means connected to said turntable for pivoting said turntable on said plate whereby said boom may be extended and moved vertically and laterally relative to said frame.
Claim 2
Dependent Claim
232 words
Material-handling apparatus for lifting barrels, cans, or the like comprising a frame, a power lift mechanism including a boom and can-engaging means connected to one end of said boom, means supporting said boom from said frame for universal directional movement, said support means comprising a support plate fixed to said frame, a turntable pivotally mounted on said plate, guide means comprising spaced tracks mounted on said turntable, extension means comprising spaced members mounted within said tracks for longitudinal movement relative thereto, said boom being pivotally supported between said spaced members, a first hydraulic cylinder having one end connected to said guide means and its other end connected to said extension means for moving said extension means in said guide means, a second hydraulic cylinder connected between said extension means and said boom to pivot said boom vertically, means supporting said second hydraulic cylinder from said spaced members including a pair of upright plates between which said second hydraulic cylinder is positioned, a pair of bars extending from the forward end of said members upwardly to said upright plates, whereby said bars and said upright plates form a guide channel for said boom as it is pivoted vertically upon actuation of said second cylinder, and actuating means connected to said turntable for pivoting said turntable on said plate whereby said boom may be extended and moved vertically and laterally relative to said frame.
Claim 3
Dependent Claim
34 words
Material-handling apparatus as defined in claim 1 comprising a pair of lugs mounted on the forward end of said boom, said lugs engaging said guide bars to limit vertical pivotal movement of said boom.
Claim 4
Dependent Claim
209 words
Material-handling apparatus for lifting barrels, cans, or the like, comprising a frame, a power lift mechanism including a boom and can-engaging means connected at one end to said boom, means supporting said boom from said frame for universal directional movement, said support means comprising a support plate fixed to said frame, a turntable pivotally mounted on said plate, guide means comprising spaced tracks mounted on said turntable, extension means comprising spaced members mounted within said tracks for longitudinal movement relative thereto, said boom being pivotally supported on said spaced members, a first fluid motor having one end connected to said guide means and its other end connected to said extension means for moving said extension means in said guide means, a second fluid motor connected between said extension means and said boom to pivot said boom vertically, means carried by said spaced members forming an upwardly open narrow guide channel for said boom as it is pivoted vertically upon actuation of said second motor, cooperating means on said boom and said guide channels for limiting pivotal movement of said boom, and actuating means connected to said turntable for pivoting said turntable on said plate whereby said boom may be extended and move vertically and laterally relative to said frame.
Claim 5
Dependent Claim
209 words
Material-handling apparatus for lifting barrels, cans, or the like, comprising a frame, a power lift mechanism including a boom and can-engaging means connected at one end to said boom, means supporting said boom from said frame for universal directional movement, said support means comprising a support plate fixed to said frame, a turntable pivotally mounted on said plate, guide means comprising spaced tracks mounted on said turntable, extension means comprising spaced members mounted within said tracks for longitudinal movement relative thereto, said boom being pivotally supported on said spaced members, a first fluid motor having one end connected to said guide means and its other end connected to said extension means for moving said extension means in said guide means, a second fluid motor connected between said extension means and said boom to pivot said boom vertically, means carried by said spaced members forming an upwardly open narrow guide channel for said boom as it is pivoted vertically upon actuation of said second motor, cooperating means on said boom and said guide channels for limiting pivotal movement of said boom, and actuating means connected to said turntable for pivoting said turntable on said plate whereby said boom may be extended and move vertically and laterally relative to said frame.
