A multidisc floor grinder is constructed as a wheeled device that may be moved about the floor by means of a handle. The chassis of the floor grinder supports a bearing housing on gimbals that allow the bearing housing to vary in orientation as the device is moved across an uneven floor. The gimbals are aligned to allow rotation of the bearing housing about a bearing housing axis that is parallel to the floor. The bearing housing supports a main drive shaft which extends downwardly from the bearing housing. The main drive shaft is rotatable relative to the bearing housing within its bearings. A grinder mounting frame is rotatably mounted about the main drive shaft and is supported therefrom. The grinder mounting frame is driven in rotation about the main drive shaft at a greatly reduced speed relative to the rotation of the main drive shaft. The grinder mounting frame carries a plurality of grinding elements which are also driven from the main drive shaft, but at a substantially increased speed of rotation relative thereto. The grinding elements thereby rotate not only about their own axes, but also about the axis of the main drive shaft so as to cover a relatively large floor area with relatively small grinding elements. This arrangement substantially reduces the time required to grind paint or other matter from a floor surface.

An improved vacuum shroud is provided for a grinding tool. The vacuum shroud employs a resilient bonnet with a central, axial opening therein for receiving a rotary grinder shaft therethrough. The bonnet is formed of a resilient, flexible, plastic material having a roof with a skirt at the periphery of the roof that laterally surrounds the grinder disk. A reinforcement plate at the undersurface of the roof protects the roof of the vacuum shroud when the grinder body is tilted at an incline toward a work surface so as to exert a greater pressure on one portion of the grinding face of the grinding disk than another. The peripheral region of the roof of the bonnet is flexible enough to permit orientation of the grinder tool body at various angles of inclination relative to the work surface while still maintaining contact between the work surface and the lower edge of the bonnet skirt throughout its entire length. The improved vacuum shroud thereby maintains substantially complete contact between the skirt of the vacuum shroud bonnet and the work surface regardless of the angle of orientation of the grinder tool body relative to the work surface. This aids in confining airborne particles within the plenum located beneath the vacuum shroud and above the work surface, while at the same time preserving a high degree of suction within the plenum.

A bed rail cover for removable placement over a bed side rail comprises two spaced, opposed side panels joined along their side and top edges to a border strip, the panels and border strip being composed of an elastomeric material. A flap of elastomeric material attaches the cover to the bed, preventing bed occupants from placing their appendages through the gap between the mattress and the rail. Use of elastomeric material allows the cover to accommodate changes in the relative positions of the mattress and rails and between rail segments when the mattress position is adjusted.

A modular portable handrail system employs cantilever arm/counter-weight anchor assemblies. Bases attach to opposing ends of the cantilever arms. A pail-like receptacle is receivable on one of the bases and interlockable with the base. The receptacle is filled with water, sand or other material to provide the counter-weight mass.

A lifeline safety system for a pitched roof employs a frame for mounting a lifeline system above the peak of the roof. Shoulders extend from the frame and engage opposing sides of the roof. An anchor comprising a generally J-shaped bolt secures the bracket assembly to the roof. The bolt has a hook which engages the underside of the rafter. A nut has a pair of arms for torquing the nut to the bolt. In one embodiment, two roof mounting pods are pivotally mounted to a shoe which receives a retractable lifeline housing.

A pile cutter support comprises a pair of sections which engage opposing faces of a pile. Platforms integrally extend from the engagement portions in a generally perpendicular relationship so as to form a guide and a support for a cutter. The sections are pivotal between a deployed position wherein the sections are engageable against adjacent faces of the pile and a folded compact carrying mode. A ratchet belt is employed to secure the support at a fixed vertical position of the pile.

An attachment is provided for a saw or other power tool having a rotary shaft and a circular blade mounted on the shaft. A substitute saw blade guard is fastened on the saw housing to define a dust confining channel about the periphery of a portion of the circular rotary saw blade. A shaft extension is fastened to the exposed tip of the shaft and an impeller is fastened to the shaft extension outside of the dust confining channel. A bonnet with an internal dust transfer passageway is secured relative to the dust guard to confine the impeller within an impeller enclosure. Operation of the rotary blade causes the impeller to rotate to create a suction, thereby drawing air and dust from the channel about the periphery of the rotary blade and into the vortex created at the axial center of the impeller. The impeller discharges air laden with dust from a discharge outlet in the impeller bonnet.

A lifeline safety system for a pitched roof employs a frame for mounting a lifeline system above the peak of the roof. Shoulders extend from the frame and engage opposing sides of the roof. An anchor comprising a generally J-shaped bolt secures the bracket assembly to the roof. The bolt has a hook which engages the underside of the rafter. A nut has a pair of arms for torquing the nut to the bolt.

A debris barrier for a high rise construction structure comprises a woven flexible mesh netting. A cord longitudinally extends along the top of the netting to form a reinforced border. The top of the netting is clipped to a safety cable so as to vertically suspend a portion of the netting. An anchoring strip is fastened to the netting. The netting is anchored to the floor slab by driving fasteners through the anchoring strip.
