Abstract: A bifurcated hose junction is provided for a pole mounted abrading device with vacuum assisted particulate removal. The junction is actuated by the movement of the sanding pad assembly. When a. short side of the rectangular sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction is displaced laterally in relation to the linear axis of the handle. When a long side of the sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction rotates in place, thereby allowing the sanding pad a comprehensive range of motion, in relation to the handle. The range of motion enables the operator to close the angle between sanding pad and the handle, and maintain planar contact between the sanding screen and the work surface, when working in constricted areas.

Abstract: The orbital sander of the present invention eliminates many of the disadvantages of the prior art sanders by providing a compact, lightweight, and economical sander having a body and shroud formed from an injection-molded synthetic polymeric material. The head is replaced using a built-in plunger which engages notches in the spindle, without the need for tools. The built-in plunger enables the flexible shroud of the prior art to be replaced with a rigid polymeric shroud positioned with a minimal gap between the shroud and the head or shoe. The polymeric shroud is attached to the rest of the polymeric body structure by three screws and two pins. The pins project upwardly from the polymeric shroud and into precise engagement with the polymeric body structure, thus reducing the required drilling and tapping, providing rotational stability, and increasing the strength of the connection between the two parts.

Abstract: A bifurcated hose junction is provided for a pole mounted abrading device with vacuum assisted particulate removal. The junction is actuated by the movement of the sanding pad assembly. When a short side of the rectangular sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction is displaced laterally in relation to the linear axis of the handle. When a long side of the sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction rotates in place, thereby allowing the sanding pad a comprehensive range of motion, in relation to the handle. The range of motion enables the operator to close the angle between sanding pad and the handle, and maintain planar contact between the sanding screen and the work surface, when working in constricted areas.

Abstract: A lens pad is provided for use on a lens clamp. The lens pad comprises a lens-engaging surface which, in turn, has a lens-facing recess located substantially centrally thereon. The lens-engaging surface thus is annular. Alternatively, the lens-engaging surface is more resilient toward a center thereof than toward a periphery thereof. Forces exerted by the lens pad against a surface of a lens when the lens pad is pressed against the surface therefore are less concentrated than such forces would be if the lens-engaging surface had no recess or variation in resiliency. Also provided is a clamp pad assembly. The clamp pad assembly includes a lens pad and a rotatable body for rotatably connecting the lens pad, at least indirectly, to a clamp arm. The clamp pad assembly also may include a swivel member which is pivotally mounted to the rotatable body for rotation therewith and for pivoting with respect thereto, in which case, the lens pad is mounted to the swivel member for rotation and pivoting therewith.

The reclaim duct receives particulate material, together with debris produced by the action of the material on the surface which rebounds from the surface, and feeds the debris and particulate material to the reclaim hopper. The central axis of the reclaim duct follows a three-dimensionally curved path which describes an upward turn through approximately 90.degree. and also an arc of about 145.degree. in an imaginary horizontal plane perpendicular to the vertical surface. The upper end of the reclaim duct is connected to the reclaim hopper.

Abstract: About a rigid longitudinal extension a sleeve is frictionally suspended such that the extension may reciprocate freely within the sleeve while remaining relatively stationary longitudinally. The rear end of the extension is attachable to a reciprocating portable power tool and the forward end is attached to a tool head. In operation, the extension and the tool head reciprocate while the sleeve, grasped in one hand, is frictionally isolated from the reciprocation and consequently insulated from the vibration associated with the operation of a portable reciprocating portable power tool. A coupling upon the forward end of the extension facilitates the attachment of a variety of different tool ends. Frictional suspension of the sleeve about the extension by using a pair of springs or by using bearings between the sleeve and the extension is suggested.

Abstract: Current pole mounted vacuum sanders have universal connections between the pole and sander which permit the sanding pad to lift off the sanding surface when pressure is applied. The present invention provides a universal connection between the pole and base of the vacuum hand sanding device which allows the head to be semi-locked into position when the pole is angled to the working surface to prevent the pad lifting from the surface.

Abstract: A vibration stabilizer is provided for a power tool such as a sander or the like which has a pivotally oscillating driveshaft for supporting a tool head. The tool is provided with an elongate body having an internal cavity aligned along a longitudinal axis for receiving a drive motor therein. A driveshaft is pivotally supported upon the elongate body rotatable about a pivot axis. The drive motor operatively engages the driveshaft to cause the driveshaft to pivotally oscillate within a limited angular range when the drive motor is energized. Relative vibration between the tool head and the elongate body is minimized by an elastic ring which extends about the driveshaft and is interposed between the tool head and the elongate body. The elastic ring is loaded in compression axially biasing the tool head and the attached driveshaft in a direction away from the elongate body.

Abstract: A device that is intended as a snap on attachment for an existing pole-mounted sander. Snap-fit receiving elements are attached to the poleward side of the generally rectangular and planar abrasive receiving surface and the pole itself is slid through and retained against lateral movement by a central rigid collar. This then brings a substantially rigid mouth portion that is configured to extend about the periphery of the receiving surface, and that also carries upon it the protruding snap members, into a proximal relationship with the abrasive receiving surface whereby the mutually engageable snap members hold the present invention in place to form a continuous intake port. A flexible collar portion lies between the mouth portion and the rigid collar portion to allow for tilting of the abrasive surface during use, as is common on the pole mounted sanders currently in use.
