Claim 3

The apparatus of claim 1 further comprising means for engaging and centering said drum with respect to said frame member.

Claim 4

The apparatus of claim 1 wherein said latch extends downwardly and is adapted to engage the inner surface of the upstanding upper rim of a drum.

Claim 5

The apparatus of claim 1 further comprising locking means on the lower end of said frame member for engaging the lower rim of a drum to substantially prevent movement thereof laterally with respect to said frame member.

Claim 6

The apparatus of claim 1 wherein said base support means comprises a base plate extending outwardly in substantially transverse relation to said frame member, and further comprising upstanding locking means on said base plate spaced from said frame member and being of height sufficient to engage the inside surface of the lower rim of a drum when said rim is resting on said base plate to limit lateral movement of the drum with respect to said frame member.

Claim 7

The apparatus of claim 5 wherein said base plate extends outwardly a distance less than the radius of the drum to be handled.

Claim 8

The apparatus of claim 5 further comprising centering means on said base plate for engaging and centering the drum with respect to said frame member.

Claim 9

The apparatus of claim 1 wherein said latch means further comprises slide means mounted on the outer portion of said latch arm and having an inclined surface engageable with the upper surface of a drum as the apparatus is being moved toward the drum, whereby said latch arm is maintained in a release position by said slide means so that said latch moves over the upper rim of the drum before engaging the inner surface thereof.

Claim 10

The apparatus of claim 8 further comprising means for limiting the downward pivotal movement of said latch arm so that said inclined surface of said slide means is in alignment with the upper surface of a drum to be handled by said apparatus.

Claim 11

Apparatus for handling drums or the like having an upper rim and a lower rim, comprising: an elongated frame member having an upper end and a lower end, means for attaching said frame member to a lift mechanism on a vehicle, a base plate attached to the lower end of said frame member and extending generally laterally outwardly therefrom, drum centering means mounted on said base plate for substantially aligning and centering a drum to be handled with respect to said frame member and said base plate, raised stop means on said base plate and spaced laterally from said frame member so as to be disposed in juxtaposition to and radially inwardly of the lower rim of a drum when the drum is seated upon said base plate surface, a latch arm pivotally mounted on said upper end of said frame member and extending generally laterally outwardly therefrom, a latch extending downwardly from said latch arm and spaced laterally from said frame member a distance sufficient to enable said latch to engage the inside of the upper rim of a drum when the upper rim is in close proximity to said frame member, said latch arm being movable between a lower engaged position wherein said latch is in engagement with the upper rim of a drum and an upper release position wherein said latch is removed from said upper rim, an upwardly and outwardly extending slide member on and spaced laterally outwardly of said latch, said slide member being positioned to engage the upper surface of a drum in advance of said latch as said frame member is being moved toward the drum so that said latch arm is lifted and said latch is moved over the upper surface of the drum during the loading of the drum, and release means on said latch arm for selectively pivoting said latch arm to said release position.

Claim 12

Apparatus for handling drums or the like having an upper rim and a lower rim, comprising: an elongated frame member having an upper end and a lower end, means for attaching said frame member to a lift mechanism on a vehicle, a base plate attached to the lower end of said frame member and extending generally laterally outwardly therefrom, drum centering means mounted on said base plate for substantially aligning and centering a drum to be handled with respect to said frame member and said base plate, raised stop means on said base plate and spaced laterally from said frame member so as to be disposed in juxtaposition to and radially inwardly of the lower rim of a drum when the drum is seated upon said base plate surface, a latch arm pivotally mounted on said upper end of said frame member and extending generally laterally outwardly therefrom, a latch extending downwardly from said latch arm and spaced laterally from said frame member a distance sufficient to enable said latch to engage the inside of the upper rim of a drum when the upper rim is in close proximity to said frame member, said latch arm being movable between a lower engaged position wherein said latch is in engagement with the upper rim of a drum and an upper release position wherein said latch is removed from said upper rim, an upwardly and outwardly extending slide member on and spaced laterally outwardly of said latch, said slide member being positioned to engage the upper surface of a drum in advance of said latch as said frame member is being moved toward the drum so that said latch arm is lifted and said latch is moved over the upper surface of the drum during the loading of the drum, and release means on said latch arm for selectively pivoting said latch arm to said release position.

Claim 13

Apparatus for handling a drum or the like, comprising: a frame member having an upper end and a lower end, said frame member having a drum contact surface on the upper end thereof for engaging the upper portion of a drum when it is moved into contact with an upstanding drum to tilt said drum, base support means attached to the lower end of said frame member and extending generally laterally outwardly therefrom a distance sufficient to engage and support a portion of the bottom of a drum, said base support means comprising a base plate extending outwardly in substantially transverse relation to said frame member, and upstanding locking means on said base plate spaced from said frame member and being of a height sufficient to engage the inside surface of the lower rim of a drum when said rim is resting on said base plate to limit lateral movement of the drum with respect to said frame member, latch means movably secured to the upper end of said frame member and extending generally laterally outwardly therefrom, saId latch means comprising a latch engageable with the upper portion of a drum when the drum is engaged by said contact surface and said latch means is in a locking position. means for moving said latch means to a release position wherein said latch is out of engagement with the upper drum portion, attaching means on said frame member for permitting attachment of said apparatus to a lift mechanism, and centering means on said base plate for engaging and centering the drum with respect to said frame member, said centering means comprising upstanding members mounted on said base plate and engagable with the lower portion of the drum.

Claim 14

Apparatus for handling a drum or the like, comprising: a frame member having an upper end and a lower end, said frame member having a drum contact surface on the upper end thereof for engaging the upper portion of a drum when it is moved into contact with an upstanding drum to tilt said drum, base support means attached to the lower end of said frame member and extending generally laterally outwardly therefrom a distance sufficient to engage and support a portion of the bottom of a drum, said base support means comprising a base plate extending outwardly in substantially transverse relation to said frame member, and upstanding locking means on said base plate spaced from said frame member and being of a height sufficient to engage the inside surface of the lower rim of a drum when said rim is resting on said base plate to limit lateral movement of the drum with respect to said frame member, latch means movably secured to the upper end of said frame member and extending generally laterally outwardly therefrom, saId latch means comprising a latch engageable with the upper portion of a drum when the drum is engaged by said contact surface and said latch means is in a locking position. means for moving said latch means to a release position wherein said latch is out of engagement with the upper drum portion, attaching means on said frame member for permitting attachment of said apparatus to a lift mechanism, and centering means on said base plate for engaging and centering the drum with respect to said frame member, said centering means comprising upstanding members mounted on said base plate and engagable with the lower portion of the drum.
