摘要： The handle comprises two elongated structural elements slidably engaged to move relative to each other parallel to their longitudinal axes with mechanical power transmission apparatus attached to the handle and also comprising two elongated elements engaged such that they are moveable relative to each other parallel to their longitudinal axes. The length of the power transmission apparatus adjusts automatically to match adjustment of the length of the handle. A rotary power transmission apparatus is disclosed.

摘要： The subject handle comprises basic structure in the form of two tubes, one telescoped into the other, fitted with mechanism to clamp them together at any adjusted length. The clamp mechanism is well known in the art, being used in tent poles, boat hooks and the like and is operable by rotating the tubes relative to each other. The handle further comprises mechanism for interconnecting a lever at one end with clamping mechanism at the other. This mechanism disengages during handle length adjustment and automatically engages once the length adjustment is made and locked and the interconnecting mechanism is operated.

摘要： The flat finishing box has attachable/detachable heads each of which comprises a structural part incorporating a mouth and to which an edge assembly and edge assembly adjustment apparatus are attached. Heads are provided for dispensing mud in each of the three standard swath widths, 7", 10" and 12", so that any swath width can be dispensed from one box by interchanging heads attached to the box. The box cover is one extrusion and the bottom and back are another. The hinged edge of the cover has a cylindrical segment along the edge which fits into a partial cylindrical groove in the back, providing a leak proof hinge. Channels are provided to enhance mud flow from portions of the box beyond the width of the mouth of the head being used to the portion within the mouth width.
