Abstract
Abstract The drum retainer includes a platform for supporting a plurality of drums thereon in an upright condition. A hold-down mechanism extends upright from the platform with the drums arranged circumferentially relative thereto. The hold-down mechanism engages the tops of the drums and provides for their securement between the hold-down mechanism and the platform. The platform is spaced above the floor by floor contacting members having teeth that penetrate the floor by virtue of the weight of the drum laden retainer to generally restrain the drum retainer against movement.

Claim 4
Dependent Claim
68 words
The structure as set forth in claim 1 wherein the floor piercing means are teeth provided at the respective ends of the runners, with said teeth at the forward end of the runners projecting downwardly and forwardly and the teeth at the rear end of the runners projecting downwardly and rearwardly to generally resist movement due to forces imposed from either the forward direction or the rear direction.
Claim 5
Dependent Claim
19 words

Claim 6
Dependent Claim
140 words
The structure as set forth in claim 1 wherein the means associated with the threaded member to impose a hold-down pressure on the plate member includes a handle member which is pivotally attached adjacent to the upper end of the threaded member, said handle member being pivotal between a position generally axially aligned with the threaded member and a position generally normal to the threaded member, and cam means on the handle member adjacent to the handle member pivot axis, said cam means providing an increasing radius relative to the pivot axis when the handle member is pivoted from the axially aligned position toward the normal position thereof to impose an added increment of hold-down pressure on the plate member and terminating with a flat to generally lock the handle member in the position generally normal to the threaded member.
Claim 7
Dependent Claim
33 words
The structure as set forth in claim 1 wherein the tubular member section comprises a regular polygon and the nut engaged upon the threaded member has sides corresponding to the tubular member section.
Claim 8
Dependent Claim
53 words
The structure as set forth in claim 1 wherein the tubular member telescopically receives the threaded member and is pivotally connected to the platform means, said tubular member with telescoped threaded member being pivotal to a generally horizontal position at rest on the platform means when the drum retainer is not in use.
Claim 9
Dependent Claim
27 words
The structure as set forth in claim 1 wherein the hold-down means are vertically extendible and adapted to exert a pressure on the top of the drums.
Claim 10
Dependent Claim
51 words
The structure as set forth in claim 1 wherein the hold-down means are pivotally connected to the platform means for movement between the upright position and a generally horizontal position, said generally horizontal position for the hold-down means providing for stacking and nesting of the drum retainer when not in use.
Claim 11
Dependent Claim
218 words
In a retainer for a plurality of drums, platform means for supporting drums thereon disposed upright on end, said platform means having a forward edge and a rear edge and being generally symmetrical relative to a fore-and-aft extending centerline, hold-down means extending upright from the platform means, said drums being arranged circumferentially relative to the hold-down means and being engaged at their top by the hold-down means to provide for their securement between the hold-down means and the platform means, and a pair of fore-and-aft extending, transversely spaced runners disposed a given distance on opposite sides of said centerline and beneath the platform means to space the platform means above the floor, said runners having floor piercing means projecting downwardly therefrom to engage and pierce the floor and thereby generally restrain the drum retainer against movement, wherein the platform means has a capacity for supporting three drums arranged triangularly and in contact with each other, one of said drums being disposed forwardly with its centerline generally intersecting said centerline of the platform means and the other two drums being disposed rearwardly and generally symmetrically with respect to said centerline of the platform means, and with said runners generally extending beneath the centerlines of the rearwardly disposed drums and beneath the opposed outer portions of the forwardly disposed drum.
