Abstract: A contoured surface planing apparatus for removing proud-standing material from a contoured surface without damaging the surface. The apparatus may include a tool comprising a motor-driven rotary cutter supported by a main body for rotation about a cutter axis, and orientation contact points spaced around the cutter and defining an orientation contact plane disposed parallel to the cutter axis.

Abstract: An apparatus for smoothing a workpiece has a housing that is displaced relative to the workpiece in a direction and that carries a pair of augers provided with respective screwthreads having outer edges in contact with the workpiece. These augers are rotated on the housing about respective generally parallel axes transverse to the direction so as to scrape the workpiece with the screwthreads. Furthermore the augers are of such a hand and the are rotated in such a direction that the augers exert on the workpiece opposite axially directed forces.

Abstract: A portable wood sander comprising retractable interim fences to support the tool, while sanding, on the surface of an independent supporting structure, other than the surface of the work piece being sanded, and other straddling fences to stop the abrasive cut of the work piece by the sander when a predetermined angle and depth of cut of the top surface of the work piece has been obtained and the straddling fences contact the surface of the said independent supporting structure. The support, control and stop means or fences may be an integral part of the sander or be attachable to said tool or to a previously manufactured sander and may contain means for the fences to be adjustable vertically, horizontally or on an angle, independently or together, in order to obtain a predetermined angle and depth of cut of a work piece by mechanical means.

Abstract: Rolls of paper are converted by unwinding, cutting and stacking into a relatively high stack of paper sheets of a predetermined uniform size. At least one of the vertical corners of the stack is removed by running an electrically driven manual planer down the corner so as to leave each sheet with one or more corners having a notch for use in orienting the sheet such as in feeding it into a copy machine. The planer is equipped with guide means so that the corner notches all have the same predetermined size and shape. The planer is preferably equipped with a vacuum hose which removes the debris as it is formed and conveys it to a vacuumized collection chamber. Preferably, the stacks of paper sheets are accumulated onto the deck of a pallet having on the underside a support integrally formed from a sheet of material so as to have parallel channel formations adjacent to and inset from opposite sides of the deck. It is also desired to provide a center-post or pedestal.

Abstract: In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.
