Abstract

Abstract A barrel handling and dumping device for use with a fork lift truck comprises a barrel support plate and a pair of laterally spaced rearwardly extending bracket arms hinged to their front edges to the underface of the support plate and overlying the fork tongues and anchored thereto by pairs of longitudinally spaced collars affixed to the underfaces of the bracket arms and slidably engaging the torques, the arms being locked in position by set screws. Front and rear chains attached to the support plate carry hooks engaging the barrel rim, one of the chains having a chain tightener toggle member and an upwardly propelling stop member is located at the support plate front border, actuating arm projects forwardly medially from the support plate. To dump a barrel carried by the support plate the truck is advanced to bring the actuating arm beneath a rearwardly projecting tripping projection on the upper part of a receiver, and the fork raised to bring the actuating member into enagement with the trip and then advanced and raised to invert the barrel.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 218 words
A receptacle handling and dumping device for use with a fork lift truck including a motor driven vertically movable longitudinally forwardly projecting lift member and a receiver container having a top opening and an outwardly projecting trip defining upper member, said device comprising: coupling means releasably engaging said lift member and extending at least to the forward end of said lift member; a receptacle supporting tilt member positioned above and connected to the forward portion of said coupling means for swinging about a transverse axis between a retracted upright and an inverted position; an actuating member positioned at the forward end of said tilt member and movable therewith; and means for releasably anchoring to said tilt member an upright receptacle located thereon, such that the center of gravity of said receptacle is rearwardly displaced from said transverse axis, whereby upon the movement of said lift truck to bring said actuating member to a position underlying said trip and the raising of said lift member, the rising of said actuating member is restricted to thereby swing said tilt member forwardly about said transverse axis so that the center of gravity of said receptacle moves forwardly of said transverse axis such that said receptacle pivots about said transverse axis and freely rotates to an inverted position below said lift member.
Claim 2
Dependent Claim 218 words
A receptacle handling and dumping device for use with a fork lift truck including a motor driven vertically movable longitudinally forwardly projecting lift member and a receiver container having a top opening and an outwardly projecting trip defining upper member, said device comprising: coupling means releasably engaging said lift member and extending at least to the forward end of said lift member; a receptacle supporting tilt member positioned above and connected to the forward portion of said coupling means for swinging about a transverse axis between a retracted upright and an inverted position; an actuating member positioned at the forward end of said tilt member and movable therewith; and means for releasably anchoring to said tilt member an upright receptacle located thereon, such that the center of gravity of said receptacle is rearwardly displaced from said transverse axis, whereby upon the movement of said lift truck to bring said actuating member to a position underlying said trip and the raising of said lift member, the rising of said actuating member is restricted to thereby swing said tilt member forwardly about said transverse axis so that the center of gravity of said receptacle moves forwardly of said transverse axis such that said receptacle pivots about said transverse axis and freely rotates to an inverted position below said lift member.
Claim 3
Dependent Claim 55 words
The device of claim 1 wherein said lift member comprises a forwardly projecting fork including a pair of transversely spaced forwardly projecting prongs and said bracket comprises a pair of correspondingly transversely spaced arms superimposed on and projecting forwardly of said prongs, and hinged at their forward ends to the underface of said tilt member.
Claim 4
Dependent Claim 25 words
The device of claim 2 wherein each of said bracket arms includes a pair of longitudinally spaced depending collars tightly slideably engaging a respective prong.
Claim 5
Dependent Claim 22 words
The device of claim 3 including means for releasing locking each of said bracket arms against longitudinal movement along a respective prong.
Claim 6
Dependent Claim 17 words
The device of claim 1 including means for releasably locking said tilt member in its retracted position.
Claim 7
Dependent Claim 29 words
The device of claim 1 wherein said tilt member comprises a receptacle supporting plate and said actuating member comprises a finger member projecting longitudinally medially forwardly from said plate.
Claim 8
Dependent Claim 22 words
The device of claim 6 comprising an upright receptacle locating peripheral wall positioned on the top face of said tilt member plate.
Claim 9
Dependent Claim 46 words
The device of claim 6 comprising means for limiting the forward movement of said receptacle along said tilt member plate including an upright projecting upwardly from the forward portion of said plate and transversely extending receptacle engaging wings affixed to the upper part of said upright.
Claim 10
Dependent Claim 48 words
The device of claim 1 wherein said anchoring means comprises a pair of anchoring cables anchored at their lower ends to front and rear positions on said tilt member plate and hooks affixed to the upper ends of said cables and releasably engaging the rim of said receptacle.
Claim 11
Dependent Claim 38 words
The device of claim 9 including a toggle member connected to at least one of said cables between the ends thereof for contracting said cable to a tightened condition and releasably locking the cable in said tightened condition.
