US 6,645,054 B2 · Portable drum sander

Abstract

A portable drum sander, including a base, a drum mounted for rotation on the base for carrying at least one grade of sand paper on a peripheral surface thereof, a feed table carried on the base and having a slot therein through which the drum is exposed for rotating contact with a workpiece to be sanded. The feed table includes an infeed table segment upstream of the slot and an outfeed table segment downstream of the slot for supporting the workpiece during passage over the slot in contact with the drum, and a pivot mounting the feed table adjacent a downstream end of the outfeed table segment for pivotal movement of the feed table to a desired height with reference to the drum. A height adjustment lock cooperates with the infeed table segment for locking the feed table into a locked position at the desired height with reference to the drum.

Dependent claims

A portable drum sander, comprising:

(a) a base;
(b) a drum mounted for rotation on the base and adapted for receiving and simultaneously carrying at least two different grades of sandpaper side-by-side on a peripheral surface thereof;
(c) a feed table carried on the base and having a slot therein through which the drum is exposed for rotating contact with a workpiece to be sanded, said feed table including an infeed table segment upstream of the slot and an outfeed table segment downstream of the slot for supporting the workpiece during passage over the slot in contact with the drum;
(d) a pivot mounting the feed table adjacent a downstream end of the outfeed table segment for pivotal movement of the feed table to a desired height with reference to the drum;
and
(e) a height adjustment lock cooperating with the infeed table segment for locking the feed table into a locked position at the desired height with reference to the drum.

A portable drum sander comprising:

(a) a base having interconnected front, rear and left and right side plates forming a frame;
(b) a drum mounted for rotation on the base for carrying at least one grade of sandpaper on a peripheral surface thereof, said drum extending across said frame;
(c) a feed table carried on the base and having a slot therein through which the drum is exposed for rotating contact with a workpiece to be sanded, said feed table including an infeed table segment upstream of the slot and an outfeed table segment downstream of the slot for supporting the workpiece during passage over the slot in contact with the drum;
(d) a pivot mounting the feed table adjacent a downstream end of the outfeed table segment for pivotal movement of the feed table to a desired height with reference to the drum;
and
(e) a height adjustment lock cooperating with the infeed table segment for locking the feed table into a locked position at the desired height with reference to the drum, said height adjustment lock comprising:
(i) a lifter plate supporting the feed table and mounted for vertical movement relative to the front plate of the base for varying the height of the feed table within a range of vertical motion relative to the drum;
and
(ii) at least one locking device carried by said front plate for locking the lifter plate into a desired position within the range of motion.
