Portable metal drum openers allow the use of a cutting head with a relatively small diameter so that most metal drum covers can be removed without having to beat down or remove bungs in the cover. The cutting head is spring mounted so that the small diameter cutting head will not slip or stall when encountering a kink in the chime. The cutting head is tilted downward in the direction of cutting so that the cutting head would tend to move downward along the chime when making the cut, however, the cutting head is physically restrained from moving downward past a selected chime cutting height. The selected chime cutting height is preferably adjusted by adjusting the position of a shaft collar along threads on a cutting shaft that projects perpendicularly from the cutting head. It is preferred that the drum opener be driven either manually, or by an electric DC motor.

Portable metal drum opening apparatus

A fuse recloser for placing a fuse in a vertically oriented fuse holder includes a channel-shaped fuse shoe pivotally mounted within a channel-shaped support. The side arms of the shoe and support flex and the shoe releasably grips a fuse. The exterior of the fuse shoe includes cam surfaces which engage with the outer ends of the support which serve to collapse the shoe onto the fuse while permitting a forced release of the fuse shoe from the support. A release lever is provided for initial separation of the fuse shoe and support, after which the shoe is readily removed from the fuse. A U-shaped handle extends from the support outwardly and then rearwardly in offset relation to the support. A flexible line is secured to the outer end of the offset handle member with a fuse in the shoe and the shoe within the support. The one end of the fuse is placed in lower pivotal mount on the fuse holder and depends downwardly therefrom with the offset handle member extending upwardly. The lineman demounts from the pole, moves from the base of the pole and then pulls on the end of the line to snap the fuse into place. The lineman may then return to the fuse location, and use a switch pole to activate the release lever to release the shoe from the support and then remove the recloser from the fuse by pivoting the recloser on the upper end of the fuse holder.
