Abstract: An improved flash dryer oven is disclosed which operates in a self-cleaning manner that continuously removes dust and debris from the oven, thereby preventing dust and debris from interfering with the hot air flow through the oven. A self-cleaning function is provided to the flash dryer oven by routing the conveyor belt through the lower supply duct on its return path to continuously clean out lead oxide dust and particles that are located within the lower supply duct. In addition, the lower supply duct has a gabled top that will direct some of the lead oxide dust and particles off of the lower supply duct instead of the lead oxide dust and particles falling through nozzles in the top of the lower supply duct and into the lower supply duct.

Abstract: A wood planing machine includes a support carriage mounted movably on a mounting frame, a motor unit and a cutter member mounted on the support carriage, and a shield member mounted on the support carriage and pivotable between covering and uncovering positions. When the shield member is disposed at the covering position, a motor shielding portion of the shield member is disposed to cover an upper housing part of the motor unit, whereas a cutter shielding portion, which extends from the motor shielding portion, is disposed to shield a top side of the cutter member.

Abstract: An apparatus for securely positioning thin work pieces for accurate joining of edges using a standard woodworker's bench plane. The plane slides on its side surface on a lower platen surface, and the blade is guided in a very straight path for the cut by a vertical surface which contacts the portion of the sole of the plane lateral to the blade. Work pieces are secured against an upper platen surface by a clamping bar, which is attached by screws at its ends to the platen. Between the clamping bar and the work piece there is a clamping caul, which applies adjustable spaced clamping forces to the work piece by means of individual screws through the clamping bar.Attachable planing fence and miter gage accessories are also disclosed, which permit accurate repeat positioning for taper, cross-grain, and length cuts at selectable angles.
