Abstract: The invention is directed to a hand tool for cutting shavings from the surface of a workpiece of wood (or other workable material) to shape and make smooth any three-dimensional surface having concave, flat, and/or convex contours. The thickness of the shavings is modulated by the angular relationship and distance between a blade and a regulating post. An embodiment comprises a combination body and handle holding a protruding cutting blade at an angle of about 30° to the surface of the workpiece, and an adjustable protruding post in front of the cutting edge to limit the effective exposure of the cutting edge as the tool is moved into contact with the workpiece. The embodiments provide a full view of the cutting zone and unrestricted one-hand use on surfaces of any contour.

Abstract: A multi-purpose bracket which clamps across both gunwales of a canoe and presents a standardized pad at each side of the hull to align precisely and mount rigidly a variety of accessories. These accessories include multi-hull catamaran coupling bars, portaging wheels, and any other equipment requiring a temporary but strong and secure means of attachment. The very large forces and moment loadings generated by such accessory equipment are borne directly by the bracket's strong tubular beam and then transmitted safely to the hull by distributing them through both gunwales as simple direct tension and compression forces. The standardized mounting pads provide a common basis for future development of many accessory devices that can enhance both the utility and enjoyment of canoes, while enabling such equipment to be shared and used interchangeably by any canoe equipped with a bracket according to the invention.

Abstract: A tool head for moving a tool to a workpiece and applying an axial force thereto includes a grooved tubular spindle mounted on a fixed shaft for relative axial and rotational movement. The spindle is rotated by a timing belt transmitting power from a driver timing pulley. The timing belt is fitted around the timing pulley and grooved spindle with a pair of 90.degree. twists in the loaded and unloaded sections between the two pulleys. As power is applied to the timing pulley, the belt migrates toward the end of the pulley and the spindle closest to the unloaded section of the belt; and when a resistant torque is applied to the spindle the timing belt migrates to a stable position with respect to both the timing pulley and the grooved spindle and transmits torque and an axial force to the spindle.

Abstract: The invention is a drive for transducing rotation of a motor shaft having a multiple eccentric journal having a hollow sized to fit over the motor shaft and at least one pair of journals, each member of a pair being concentric with an axis parallel to the axis of the hollow and spaced apart from its mate an equal distance on opposite sides of and coplanar with a hollow axis. The eccentric journal is secured to the motor shaft and a rotational bearing is attached to each journal. Associated with each bearing is a transmission wheel having means for mounting the wheel to the bearing eccentrically with respect to the transmission wheel an equal radial amount from the axis of rotational symmetry of each transmission wheel as compared to the other transmission wheel. The invention provides a high ratio, single stage transmission with few moving parts, and without complicated case, lubrication or torque arms.

Abstract: An actuator including a housing having an internal cavity, a flexible but inextensible belt mounted so as to form an open-ended loop within the cavity, and a seal/port assembly closing the open end of the loop and providing for fluid flow into the loop. One end of the loop is fixed. Fluid flow into the loop moves the belt and causes the area enclosed by (and in preferred embodiments the length of the periphery of) the loop to increase.

Abstract: Disclosed is a shaper cutterhead utilizing an assembly that locates, captivates and firmly clamps two standard cutter bits that each include a hole designed to be engaged by solid lugs of a hub. Tee-slotted clamping collars that surround the hub slide laterally into place by engaging grooves in both bits and lock the bits rigidly when the machine spindle is tightened.

Abstract: A rotor comprises two rotor sections mounted coaxially on a shaft for limited axial movement relative to each other. The two sections are slightly spaced axially from each other and one defines a peripheral porting surface engaging a second porting surface defined by a porting member. The rotor has a plurality of bores each carrying a piston and including a first portion defined by one of the rotor sections, a second portion defined by the other of the rotor sections, and an intermediate portion extending between the rotor sections. The pistons engage a cam comprising a sheet pressed into a configuration including a plurality of coaxial annular sheet portions. One sheet portion defines the undulating cam surface; two other sheet portions extend parallel to each other and perpendicular to the one portion from the opposite sides of the one portion.
