Abstract
Abstract An assembly for the manual movement of relatively heavy material in a thin walled, handleless, and stackable drum without damage to the drum. The assembly includes a thin walled drum having an upper chine, a cover mounted on the chine and closing the drum, the cover having an annular downwardly extending groove located adjacent the chine and a v-type toggle clamp assembly connecting the cover to the drum along with a pair of spaced, detachable handle assemblies. Each handle assembly has a bracket having a pair of spaced abutments to engage the under side of the drum chine, a handle means pivotally mounted on the bracket to extend into the cover groove to secure the handle assembly to the drum and cover and a bracket strap to prevent rotation of the handle assembly about the drum chine during the lifting of the drum.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A detachable handles and drum assembly comprising: (a) an open top drum for the transport of material, said drum having an upper chine surrounding said open top; (b) a cover enclosing said open top of said drum and extending over said chine, said cover having an annular groove extending below the top of said cover and located adjacent said chine; (c) a pair of detachable handle assemblies detachably connected to said drum and said cover at spaced intervals, each handle assembly comprising: a bracket having a pair of spaced supports engaging the underside of said chine, said bracket also having an upper elongated portion contacting and extending over the top of said cover, a handle pivotally mounted on said bracket and a plunger movably mounted on said bracket and extending into said groove between said supports to secure the handle assembly to said drum and cover, said elongated portion preventing rotation of said handle assembly about said chine during lifting of said drum.
Claim 2
Dependent Claim
163 words
A detachable handles and drum assembly comprising: (a) an open top drum for the transport of material, said drum having an upper chine surrounding said open top; (b) a cover enclosing said open top of said drum and extending over said chine, said cover having an annular groove extending below the top of said cover and located adjacent said chine; (c) a pair of detachable handle assemblies detachably connected to said drum and said cover at spaced intervals, each handle assembly comprising: a bracket having a pair of spaced supports engaging the underside of said chine, said bracket also having an upper elongated portion contacting and extending over the top of said cover, a handle pivotally mounted on said bracket and a plunger movably mounted on said bracket and extending into said groove between said supports to secure the handle assembly to said drum and cover, said elongated portion preventing rotation of said handle assembly about said chine during lifting of said drum.
Claim 3
Dependent Claim
21 words
The assembly of claim 1 in which said handle has a head at its distal end in contact with said plunger.
Claim 4
Dependent Claim
32 words
The assembly of claim 2 further comprising stop means for said handle and spring means for biasing said plunger and said handle away from said cover for detachment of said handle assembly.
Claim 5
Dependent Claim
28 words
The assembly of claim 3 in which said elongated portion is located midway between said supports and has an opening therethrough and said plunger extends through said opening.
Claim 6
Dependent Claim
19 words
The assembly of claim 4 further comprising clamp means for clamping said cover to said drum about said chine.
Claim 7
Dependent Claim
16 words
The assembly of claim 5 in which said clamp means is a toggle, v-type clamp assembly.
Claim 8
Dependent Claim
131 words
A detachable handle assembly adapted for connection to a drum having a chine and a cover attached to the chine and closing the drum, the cover having an annular downwardly extending groove adjacent the chine, said handle assembly comprising: (a) a bracket having a pair of spaced supports adapted for engaging the underside of the chine, said bracket also having an upper, elongated portion adapted to contact and extend along the upper surface of the cover; (b) a handle pivotally mounted on said bracket; and (c) a plunger movably mounted on said bracket and adapted to travel into the cover groove between said supports to secure the handle assembly to the drum and cover, said elongated portion preventing rotation of the handle assembly about the chine during lifting of the drum.
Claim 9
Dependent Claim
131 words
A detachable handle assembly adapted for connection to a drum having a chine and a cover attached to the chine and closing the drum, the cover having an annular downwardly extending groove adjacent the chine, said handle assembly comprising: (a) a bracket having a pair of spaced supports adapted for engaging the underside of the chine, said bracket also having an upper, elongated portion adapted to contact and extend along the upper surface of the cover; (b) a handle pivotally mounted on said bracket; and (c) a plunger movably mounted on said bracket and adapted to travel into the cover groove between said supports to secure the handle assembly to the drum and cover, said elongated portion preventing rotation of the handle assembly about the chine during lifting of the drum.
Claim 10
Dependent Claim
22 words
