  • Patent number: 11246402
    Abstract: A frayed cable scaling tool is made by fraying the end of a cable so that it forms a wire brush. A collar or other way of keeping the cable from unraveling too much is necessary. When powered by a pneumatic saw power tool, the scaling tool is very effective at removing scale, rust, carbon, or other debris. The flexibility of the cable allows the frayed end of the cable to move vigorously in a random motion, which is effective for scrubbing. For some applications, it is preferred to enclose the cable and/or the collar in a guide tube.

  • Patent number: 8661609
    Abstract: Portable devices for dislodging and/or capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices include a body segment and a nose segment extending away therefrom. A high-pressure assembly generates a high-pressure airflow that is directed to a nozzle assembly in the nose segment. From the nozzle assembly, the high-pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface from which the particulate matter is being dislodged. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, is selected to impart the desired particulate matter dislodging characteristics to the device, and the device may incorporate a vacuum airflow to remove the particulate matter after such matter has been dislodged.

The present invention is comprised of a drum which is rotated at a high rate of speed by the prime mover of the grass trimming tool. The drum has a plurality of flexible bristles extending from its circumferential surface. The centrifugal force of the rotating drum extends the flexible bristles away from the surface of the drum. The extended bristles are then brought into contact with a desired surface, removing any paint, rust or other unwanted material from the surface with a minimal or surface damage to that surface. The rate at which the present invention is rotated is controlled by the motor governing device of the grass trimming tool.

  • Patent number: 4662044
    Abstract: A descaler for removing scale from steel billet before rolling of the steel billet. The descaler has a plurality of steel wire brush units each being constituted by an elongated supporting member and a multiplicity of steel wires arranged densely along the length of the supporting member and attached to the same. The steel wire brush units are loosely mounted on a rotary drum with their supporting members extending in parallel with the axis of the drum for limited radial movement and circumferential rocking movement with respect to the rotary drum. In operation of the descaler, the steel wire brush units are projected radially outwardly by the action of the centrifugal force to strongly strike and hit the billet surface to promote the removal of the scale. Since the flexing of each wire is resisted by the bundle of densely arranged steel wires, the breakage of the steel wires is suppresed to ensure a longer life of the descaler.
