First and second beams are pivotally supported on the first and second frame member ends and are generally parallel to the cross frame member. First and second scraper blades are pivotally supported, respectively, by the first and second beams, the blades being pivotal from a vertical orientation adapted for scraping a floor surface during advancement of the blade assembly in a first direction and pivotal to elevated, non-scraping orientation for retraction of the assembly in a direction opposite from the scraping direction. Preferably, a pair of end scrapers are supported by the outer ends of each of the two beams and hingedly connected thereto by a vertical hinge.

Abstract: A MIG welding torch reconditioning apparatus has a pneumatic supply line, vent means and a mechanical transmission shaft. The pneumatic supply line supplies air to the vent means for venting a directed debris-scattering air-flow against the transmission shaft proximal to exposed seals thereon. In another aspect, the apparatus has an in-line, direct-drive arrangement of a motor, a mechanical transmission shaft, and chuck means for receiving a reaming tool. Pneumatic lift means lifts the direct-drive arrangement into reaming tool engagement with the gas shield of a torch wherein the tool is operable to remove at least some of any back-splash deposits laid down on interior surfaces of the gas shield. A clamp is also provided for engaging a cylindrical body, such as a torch. The clamp includes a pair of generally orthogonally-offset faces of a “V”-block and respective gripping surfaces on gripping surface members of a pair of opposed jaws.

Abstract: An apparatus and method for removing floor covering. The apparatus includes a frame that attaches to the front end of a loader type vehicle. An arm connects to and extends forward from the frame, and has a tapered end portion with a terminal end to which a sharp blade attaches and extends forward for separating floor covering from a floor as the vehicle is driven forward pressing the blade against the floor. A deflector extends upward from on top of the tapered portion to deflect removed materials off of the top of the tapered portion. At least one resilient sweep extends downward from the frame to the floor and is vertically slidable relative to the frame to accommodate variations in the floor and vertical motion of the apparatus while maintaining contact with the floor to collect removed floor covering material ahead of the loader as floor covering is removed so that removed floor covering is not run over by the loader.

Abstract: The present invention is directed to improved apparatus' for dislodging and abrading cryolite encrustations from carbon anodes spent during aluminum smelting. Both the plow blade and flailing elements of the present invention are constructed and arranged to substantially conform to the shape of the spent carbon butts to facilitate rapid and efficient cleaning of the spent carbon anodes' surfaces. Systems and methods employing the substantially V-shaped plow blade extension and dual directional rotating flailing assemblies are also disclosed.

Abstract: A method and apparatus for reconditioning a MIG welding torch of the type having a gas shield through which gas is exhausted from the torch comprises inserting a reaming tool within an opening of the gas shield. The reaming tool is moved relative to the gas shield within the opening into contact with deposits adhered to the gas shield within the opening. An impact force is applied through the reaming tool against the deposits in the event that movement of the reaming tool relative to the gas shield is substantially inhibited by any of the deposits.

Abstract: This soldering iron cleaning apparatus comprises a main body having an introduction hole, a motor, a sensor mechanism which detects the insertion of the soldering head to the introduction hole and drives the motor, a cleaning member which removes solder remaining on the soldering head, a power transmission mechanism which drives the cleaning member by the driving force from the motor. The power transmission mechanism rotates the cleaning member, by the driving force of the motor, in such a way that the cleaning member scrapes the external surface of the soldering head from the base side to the tip side of the soldering head while turning the cleaning member around the soldering head.

Abstract: A snow removing device for removing snow and ice from the roof of semi-trailers, vans and similar vehicles. The snow removing device includes; a scraping blade slidably mounted for vertical movement between spaced apart vertical frame posts. A mechanism is provided for automatically adjusting the position of the scraping blade relative to the vehicle's roof so as to maintain a predetermined blade spacing between the blade lower peripheral edge and the vehicle's roof in order to prevent the scraping blade from damaging structures protruding from the vehicle's roof.

Abstract: To be able to easily and quickly remove adhering dirt, for example rendering mortar, from the pipes of the tubular frame of scaffolding both with the scaffold assembled and disassembled, a device is proposed which has scraper elements (2-5) which are attached to a frame (1) and which when used with a corresponding recess (6) encompasses a scaffold pipe to be cleaned over roughly half its periphery.

Abstract: The apparatus includes a water tight vehicular body of a low profile. A user controls the vehicle from a forward cockpit. The cleaning apparatus further includes both forward and rearward booms. The forward boom has a slurry trap interconnected to its forward extent. Additionally, a brush is secured to the rearward boom. Both the booms can be elevated and lowered to selectively bring the trap and brush into contact with the ground. Thus, the cleaning apparatus is adapted to be driven into the interior of a drain pipe. Thereafter, the booms are lowered such that the trap and bush come into contact with the surface to be cleaned. The vehicle can then be driven rearwardly. During the rearward travel, the brush serves to agitate floor contaminates into a slurry. Further rearward travel causes the slurry to become contained within the trap. Through this method, floor contaminates can be removed from an enclosed region such as a storm drain.
