Abstract
An adaptor mounting a drill stand on an I-beam comprises a base plate which is clamped to a flange of the beam by clamping arrangements. A table of the drill stand is then bolted to cross-members slidably mounted on the base plate. In another arrangement, the pillar of the drill stand 11 is fitted in a collar housing which is slidably mounted on a base plate. In yet another arrangement, the pillar of the drill stand is mounted on the flange of an I-beam by opposed jaws which are slidable along the pillar and locked in position by screws.
Claims8
A combination drill stand comprising a pillar and a slide mounted on said pillar for carrying an electric drill, said slide being movable along said pillar under the action of a lever, and an adapter comprising a base plate, means for attaching said base plate to a support, and means for mounting said pillar on said base plate, said means for attaching said base plate adapted to grip an edge of a flange of said support, and markings to position a drill receiving aperture in said base plate at a predetermined distance from said flange edge.
A combination drill stand comprising a pillar and a slide mounted on said pillar for carrying an electric drill, said slide movable along said pillar under the actions of a lever, and an adapter for mounting said pillar on a support, said adapter comprising a pair of opposed jaws slidable relative to one another along said pillar to grip opposite edges of a flange of said support, means for locking said jaws in position on said pillar, and means for drawing said jaws together to grip said flange, said drawing means comprises a threaded rod, rotation of said rod in one direction urging said jaws toward each other.
A combination drill stand and adaptor for mounting the drill stand on an I-beam, the drill stand comprising:
- a pillar;
- a slide mounted on the pillar and slidable along the pillar under the action of a lever, the slide being adapted to carry an electric drill;
- a table having the pillar being mounted on the table;
- the adaptor further comprising:
- a base plate;
- means for attaching the table to the base plate;
- and
- means for mounting the base plate on a flange of the I-beam, the mounting means further comprising:
- opposed jaws mounted on the base plate and slidable towards each other to grip opposed edges of the flange and fixable in position on the base plate.
